Description

  The present invention relates to a base supporting a temporary fence.

  Conventionally, when installing a temporary fence at a construction site or the like, a base having an insertion hole into which the legs of the temporary fence can be inserted is used. In addition, in order to stabilize the installation state of the temporary fence, for example, there is a technology such as forming a concrete layer inside the base or filling water or sand inside the hollow base (for example, , Patent Documents 1 and 2, etc.).

Japanese Utility Model 7-30841 JP-A-8-199865

  By the way, when a concrete layer is formed inside the base at the installation site of the temporary fence, the preparation of the base takes a relatively long time and effort when installing the temporary fence, and after the concrete layer is formed, the base There is a concern that the weight of the equipment will be heavy and the removal work etc. will be relatively difficult. In addition, when the inside of the base is filled with water or sand, there is a concern that the filling operation at the time of installation and the discharging operation at the time of removal will be relatively difficult.

  The present invention has been made to solve the problems and the like exemplified above, and an object thereof is to provide a temporary fence base which can improve the installation and removal workability. It is.

  In the following, each means suitable for solving the above object and the like will be described by item. In addition, specific effects and the like are added to the corresponding means as needed.

Means 1. A base for supporting in a posture in which a temporary fence is erected, comprising a fence main body and a plurality of legs for separating the fence main body upward from the installation surface,
Base body grounded to the installation surface,
An insertion support portion configured to be insertable into the leg portion of the temporary fence in an upright posture, and supporting the inserted leg portion;
A restriction which is provided on the upper surface side of the base main body and configured to be capable of supporting the rod-like body in a laid posture, and restricts displacement of the rod-like body in a direction intersecting with the longitudinal direction of the supported rod-like body. And a support portion,
A rod-like body extends from the restriction support of the base supporting the first leg of the predetermined temporary fence to the restriction support of the base supporting the second leg of the predetermined temporary fence. A base that is configured to be supported.

  According to the means 1, the rod-like body can be used as a weight of the base, and the installation state of the base and hence the temporary fence can be stabilized. In addition, the work for increasing the weight of the base (structure for supporting the temporary fence) is basically only to lay the rod-like body on the regulation supporting portion of the base, and furthermore, the rod-like body is plurally mounted. Since it is configured to be installed to the base, for example, the workability at the time of installing the temporary fence can be dramatically improved as compared with the case where the weight of the base is increased one by one.

  In addition, by setting the rod-like bodies over a plurality of bases, the plurality of bases can be aligned, and the workability in the work of attaching the temporary fence to the bases can be improved. In places where temporary fences are to be installed (for example, construction sites etc.), there are many cases where rod-like bodies such as single pipe pipes are used (for example, cases used for installing temporary scaffolds). The body can be used to increase the weight of the base. Moreover, if it is a single pipe pipe, storage and transportation are relatively easy, and can be used for relative ease.

  When removing the temporary fence, it is possible to remove the rod-shaped body from the plurality of bases at once by lifting the rod-shaped body. Furthermore, by removing the rod-like body, the weight of the base can be reduced and the base can be recovered. Therefore, removal work of the temporary fence can be performed relatively smoothly and quickly.

  In addition, in the case where a gap is formed between the fence main body supported in the standing posture and the installation surface, empty cans, dust, etc. are illegal in the area partitioned by the temporary fence via the gap. There is a concern that it will be dumped in On the other hand, by installing the rod-like body over a plurality of bases of the temporary fence, the rod-like body extends in the gap, and the configuration only for closing the gap is not separately installed. Concern can be suppressed.

Means 2. It is a base which supports the temporary fence which the side parts of a pair of temporary fences were comprised so that connection was possible via a joint member,
At least in use of the base, the plurality of insertion support parts by one or more bases are matched with the distance between the connected side legs of the pair of temporary fences connected by the joint member. The base according to the means 1, characterized in that it is arranged so as to be arranged at an interval which is not relative to each other.

  According to the means 2, the pair of temporary fences can be connected not only by the joint members but also by the base. Therefore, a plurality of temporary fences can be connected suitably, using a joint member and a base together, preventing an inclination etc. of a temporary fence.

  Further, for example, in the use state of the base, the connection portion with the joint member in the temporary fence and the insertion support portion of the base may be located on the same straight line extending in the substantially vertical direction. In this case, the temporary fence can be pivotally displaced like a door, and the joint member and the base are used in combination, regardless of the angle between the pair of temporary fences connected to each other. The convenience can be improved.

  In addition, as a mode example regarding arrangement | positioning of the some insertion support part arrange | positioned non-relatively displaceable, in the direction where a predetermined insertion support part and a regulation support part are located in a line, the said predetermined insertion support part and another A first mode in which the insertion support portion is arranged side by side, the predetermined insertion support portion in a direction (a direction orthogonal to the predetermined direction) in which the predetermined insertion support portion and the restriction support portion are arranged; A second mode in which another insertion support portion is disposed side by side, and a third mode in which the first mode and the second mode are combined are mentioned. As a third aspect, for example, “in the use state of at least a base, a plurality of the insertion support portions by one or more bases are connected side portions among a pair of temporary fences connected by a joint member. It is configured to be arranged in a state in which relative displacement is not possible such that they are aligned in the vertical direction and in the horizontal direction in plan view at an interval that matches the interval between the side legs. It can be mentioned. In this case, when connecting a plurality of temporary fences, it is possible to increase the variation of the combination of relative positions of the legs. For example, by arranging the temporary fences adjacent to each other in a staggered manner, it becomes possible to arrange a signboard or the like without projecting it in the passage.

  Means 3. The base according to the means 1 or 2, characterized in that on the upper surface of the base main body, there is provided an inclined portion which is positioned higher than the restriction support portion and inclined downward toward the restriction support portion. Stand.

  According to the means 3, when installing the rod-like body on the base, the rod-like body is guided to the side of the regulation support portion if the rod-like body is placed on the inclined portion without being accurately placed on the regulation support portion. And will be installed in the regulatory support. Therefore, the workability at the time of installation of the rod-like body can be improved. In addition, even if the width of the regulation support portion is substantially the same as the outer diameter of the rod-like body, the reduction in the installation workability of the rod-like body can be avoided. It is possible to achieve stabilization of the installation state of the rod-like body (for more reliably preventing positional deviation of the rod-like body supported by a plurality of bases, making the direction of the rod-like body constant, etc.) . The inclined portion may be provided only on one side of the regulation support, or may be provided on both sides.

Means 4. The upper surface of the base body is provided with a projecting portion that protrudes upward from the upper side of the inclined portion,
The base described in the means 3 is provided with the insertion support portion which opens upward and can insert the leg portion of the temporary fence inside the projection.

  According to the means 4, it is possible to prevent the situation where the rod-like body drops out from the inclined portion side due to the predetermined contact with the rod-like body installed on the base. Further, by providing the insertion support portion in the projecting portion, the insertion length of the leg portion into the insertion support portion can be increased, and the leg portion can be supported more stably.

  In the configuration in which the sloped portion is provided only on one side of the regulation support portion, “in the upper surface of the base main body, a projection projecting upward also to the opposite side of the sloped portion across the regulation support portion And the insertion support portion may be provided on the inside of the protrusion. In this case, it is possible to prevent a situation in which the rod-like body guided to the inclined portion is forcefully detached from the base. Furthermore, the choice of the insertion support part which inserts a leg part increases, and the variation of installation of a temporary installation fence can be made to increase.

  Means 5. The base according to any one of the means 1 to 4, characterized in that a connecting means is provided on the side surface of the base main body for connecting the bases.

  According to the means 5, the bases can be connected to each other, and even if the single base is configured as a simple single-purpose base, diversification of the installation of temporary fences (arrangement of a plurality of temporary fences) can be achieved. be able to. Further, since the connecting means is provided on the side surface of the base main body, the configuration relating to the placement of the rod-like body in the base main body (regulation support portion of means 1 and insertion support portion, inclined portion of means 3 etc.) It is possible to avoid the situation where the connection means interferes with the

  Means 6. In the base main body, an accommodation hole which penetrates in the vertical direction and is capable of inserting an anchor pin, and a hook portion of the anchor pin which is inserted in the insertion hole can be accommodated below the forming surface of the insertion hole The base according to any one of the means 1 to 5, wherein a recess is provided.

  According to the means 6, in the case of installing a temporary fence on a non-paved ground (for example, a relatively loose ground), the anchor pin can be used to fix the base to the ground. Furthermore, even when the anchor pin is used, the hook portion of the anchor pin (the hooked portion provided by folding the upper end in a substantially L shape or the like) is accommodated in the accommodation recess and from the upper surface of the base body Even does not protrude upwards. For this reason, the rod-like body can be installed on the base without any trouble, and the anchor pin and the rod-like body can be used in combination.

  For this reason, for example, as shown in FIG. 1 etc., when arranging a pair of temporary fences 1 in the same direction and arranging them horizontally, the legs 3 of one temporary fence 1 of the temporary fences 1 adjacent to each other are connected to each other Inserting the first insertion support 15a of one base 11 of the pair of bases 11 and inserting the leg 3 of the other temporary fence 1 into the first insertion support 15a of the other base 11 The lower ends of the temporary fences 1 adjacent to each other are connected by a pair of bases 11 connected to each other. Furthermore, since the distance between the insertion recesses 6 on the side connected by the base 11 of the temporary fences 1 adjacent to each other matches the distance between the pair of insertion protrusions 25 of the joint member 23, they are adjacent to each other The joint member 23 is attached between the insertion recesses 6 of the temporary fence 1. Thereby, the upper ends of the temporary fences 1 adjacent to each other are connected by the joint member 23.

  Moreover, in this embodiment, as shown to FIG. 8, FIG. 9, when arranging a pair of temporary installation fence 1 in the same direction and arranging horizontally, the leg part of one temporary installation fence 1 among temporary installation fences 1 mutually adjacent 3 is inserted into the first insertion support 15a, and the legs 3 of the other temporary fence 1 are inserted into the second insertion support 15b, thereby connecting the lower ends of the temporary fences 1 adjacent to each other. It is also possible to select a pattern in which the base 11 is used alone. Of course, also in this case, the upper ends of the temporary fences 1 adjacent to each other can be connected by the joint member 23. In addition, illustration of the single pipe 21 is abbreviate | omitted in FIG. 8, FIG.

  In addition, the second insertion support portion 15b of one base 11 of the pair of bases 11 connected to each other as a pattern enabling connection between the upper ends of the temporary fences 1 adjacent to each other by the joint member 23 and the other The patterns for inserting the legs 3 of the temporary fence 1 adjacent to each other with respect to the second insertion support 15b of the base 11 and the second base of the one base 11 of the pair of bases 11 connected to each other It is also possible to select a pattern in which the legs 3 of the temporary fence 1 adjacent to each other are inserted into the third insertion support 15 c and the third insertion support 15 c of the other base 11.

  In addition, as installation work of the temporary installation fence 1 in this embodiment, the single pipe | tube 21 is put in order and installed along the line which the temporary installation fence 1 is scheduled to install, for example. Subsequently, the base 11 is installed so as to support each single pipe pipe 21. Furthermore, the legs 3 of the temporary fence 1 are inserted into the base 11, and the temporary fence 1 is erected. Then, the temporary fences 1 are installed by connecting the temporary fences 1 adjacent to each other by the joint member 23.

  Further, in the present embodiment, the central axis of the leg 3 (insertion support portion 15) and the central axis of the insertion recess 6 (the insertion projection 25 of the joint member 23) extend on the same straight line. As shown in 12, the temporary fence 1 can be rotationally displaced around one side of the temporary fence 1 supported by the base 11 and the joint member 23. Thereby, the simple gate (gate) which enables it to enter and exit to the field divided by temporary fence 1 can be formed. In addition, illustration of the joint member 23 is abbreviate | omitted in FIG. Further, in the case where the temporarily movable temporary fence 1 is provided as a left / right pair, as shown in FIG. 12, the pair of temporary fences 1 is closed (the free ends of the pair of temporary fences 1 are butted It is also possible to perform a simple lock by providing the joint member 23 between the insertion recesses 6 on the free end side of the pair of temporary fences 1).

  In addition, it is also possible to connect the pair of temporary fences 1 in directions orthogonal to each other. Even in such a case, as shown in FIG. 1, the leg 3 of one temporary fence 1 is inserted into the first insertion support 15a, and the leg 3 of the other temporary fence 1 is inserted into the second insertion support 15b. As shown in FIG. 13, one base 11 of the pair of bases 11 connected to each other is the pattern of using the base 11 alone and the legs 3 of one temporary fence 1 as shown in FIG. 13. Pattern in which the base 11 is connected and used in such a manner that the leg portion 3 of the other temporary fence 1 is inserted into the first insertion support portion 15a of the other base 11 by being inserted into the first insertion support 15a of And can be selected.

  Further, as shown in FIG. 14, in the support main body 12, the support main body 12 is vertically penetrated through the support main body 12 in the support recess 14, and the insertion pin 19 is inserted through the insertion hole 19 and the insertion hole 19. An accommodation recess 20 is provided which can accommodate the hook portion 28 (a hooked portion provided by folding the upper end portion in a substantially L shape or the like) below the support recess 14. ing. For example, in the case where the temporary fence 1 is installed on a ground that is not paved and where the ground is relatively loose, the anchor pin 27 may be driven into the ground via the insertion hole 19 to fix the base 11. It is possible. Further, since the hook portion 28 of the anchor pin 27 is accommodated in the accommodation recess 20, the hook portion 28 does not protrude above the support surface of the support recess 14 in the support recess 14. For this reason, it is also possible to mount the single tube pipe 21 in the support recess 14 of the base 11 fixed by the anchor pin 27. The distal end of the hook portion 28 protrudes sideways more than the base main body 12 so that a tool or the like can be easily hooked on the hook portion 28 when the anchor pin 27 is removed.

  As described above in detail, according to the present embodiment, the single pipe pipe 21 can be used as a weight of the base 11, and the installation state of the base 11, and hence the temporary fence 1, can be stabilized. . Moreover, the work for increasing the weight of the base 11 (configuration for supporting the temporary fence 1) is basically only to lay the single pipe 21 on the supporting recess 14 of the base 11 and put it on, Since the single-pipe pipe 21 is installed across a plurality of bases 11, the workability at the time of installation of the temporary fence 1 compared to, for example, the case where the weight of the bases 11 is increased one by one. Can be dramatically improved.

  In addition, by setting the single pipe pipe 21 to the plurality of bases 11, the plurality of bases 11 can be aligned, and the workability in the work of attaching the temporary fence 1 to the base 11 is improved. Can be In places where temporary fences 1 are installed (for example, construction sites etc.), there are many cases where rod-like bodies such as single pipe 21 are used (for example, cases used for installation of temporary scaffolds), The weight of the base 11 can be increased by using the single pipe pipe 21 (other steel materials are also possible). Moreover, if it is the single pipe 21, storage and transportation are relatively easy, and can be used relatively easily.

  When removing the temporary installation fence 1, the single pipe pipe 21 can be removed at once from the plurality of bases 11 only by lifting the single pipe pipe 21. Furthermore, by removing the single pipe pipe 21, the weight of the base 11 can be reduced and the collection work of the base 11 can be performed. Therefore, the removal operation of the temporary fence 1 can be performed relatively smoothly and quickly.

  In addition, when a gap is formed between the fence main body 2 supported in the standing posture and the installation surface, empty cans, dust, etc. can be formed in the area partitioned by the temporary fence 1 via the gap. May be illegally dumped. On the other hand, by installing the single pipe pipe 21 over the plurality of bases 11 of the temporary fence 1, the single pipe pipe 21 extends in the gap, and a configuration only for closing the gap is separately installed. Even if it does not, the said concern can be suppressed.

  Further, in the present embodiment, the distance between the first insertion support portion 15a of each base 11 and the second insertion support portion 15b, and between the first insertion support portions 15a of the pair of bases 11 connected to each other. Between the pair of temporary fences 1 in which the spacing, the spacing between the second insertion support portions 15b, and the spacing between the third insertion support portions 15c are connected by the joint member 23, the side leg portions connected to each other are connected It is configured to match the distance between the two. Therefore, the pair of temporary fences 1 can be connected not only by the joint member 23 but also by the base 11. Therefore, the joint members 23 and the base 11 are used in combination to prevent inclination of the temporary fence 1 and to preferably connect the plurality of temporary fences 1 (at the upper end and the lower end of the temporary fence 1) can do.

  Also, for example, in the use state of the base 11, the insertion recess 6 which is a connection portion with the joint member 23 in the temporary fence 1, and the insertion support portion 15 of the base 11 extend on the same straight line extending in the substantially vertical direction. It is supposed to be located in For this reason, as shown in FIG. 10, the temporary fence 1 can be rotationally displaced like a door, and the joint member 23 and the pair of temporary fences 1 connected to each other are at any angle. The base 11 can be used in combination, and convenience can be improved.

  In addition, the distance between the first insertion support 15a and the second insertion support 15b of one base 11, the distance between the first insertion support 15a of the pair of bases 11 connected, the second insertion support Since the intervals between the 15bs and the intervals between the third insertion support portions 15c are the same, variations in the combination of the relative positions of the leg portions 3 can be increased when connecting a plurality of temporary fences 1. For example, as shown in FIG. 8 and FIG. 9, by arranging the temporary fences 1 adjacent to each other in the back and forth direction, it becomes possible to arrange a signboard or the like without projecting it into the passage. In addition, for example, the temporary fence 1 can be inserted by inserting the legs 3 into the pair of first insertion support portions 15a of the pair of connected bases 11 and the pair of third insertion support portions 15c. It is also possible to provide two rows. In this case, both sides of the temporary fence 1 can be used as a passage partition that allows passage, and the single pipe 21 can be installed at a position that does not interfere with passersby.

  Further, on the upper surface of the base main body 12, an inclined portion 16 which is inclined downward toward the support concave portion 14 is provided. For this reason, when installing the single pipe 21 on the base 11, the single pipe 21 is supported if it is mounted on the inclined portion 16 without accurately mounting the single pipe 21 on the support recess 14. It will be guided to the recessed part 14 side, and will be installed in the support recessed part 14. Therefore, the workability at the time of installation of the single pipe 21 can be improved. In addition, even if the width of the support recess 14 is substantially the same as the outer diameter of the single pipe 21, a decrease in the installation workability of the single pipe 21 can be avoided, so the width of the support recess 14 is equal to the outer diameter of the single pipe 21. In comparison with the case where the single pipe 21 is configured relatively large, the installation state of the single pipe 21 is stabilized (a position deviation of the single pipe 21 supported by the plurality of bases 11 is more reliably prevented, The direction of the pipe 21 can be made constant, etc.).

  Furthermore, a cylindrical third projecting portion 13 c is provided on the upper surface of the base body 12 so as to protrude upward from the upper side of the inclined portion 16. For this reason, it is possible to prevent the situation in which the single pipe pipe 21 falls off from the inclined portion 16 side due to the predetermined contact with the single pipe pipe 21 installed on the base 11. In addition, a second protrusion 13 b is provided on the opposite side of the inclined portion 16 with the support recess 14 interposed therebetween. For this reason, it is possible to prevent a situation in which the single pipe 21 guided to the inclined portion 16 leaves the base 11 with excessive force. In addition, by providing the insertion support portion 15 in the projecting portion 13, the insertion length of the leg portion 3 into the insertion support portion 15 can be increased, and the leg portion 3 can be supported more stably.

  Further, on the long side surface of the base main body 12, there are provided a connection projection 17 and a connection recess 18 which can connect the bases 11 with each other. Therefore, even if the base 11 alone is configured as a simple and versatile device, the bases 11 are connected to each other, etc. to diversify the variation of the installation of the temporary fence 1 (the arrangement of the temporary fences 1). Can be Furthermore, since the connection projection 17 and the connection recess 18 are provided on the side surface of the base main body 12, the configuration etc. regarding the placement of the single pipe pipe 21 in the base main body 12 (the support recess 14, the insertion support 15, and the inclination It is possible to avoid the situation in which the connection protrusion 17 and the connection recess 18 obstruct the portion 16 and the like.

Thus, the base 11 can be fixed to the ground. Furthermore, even when the anchor pin 27 is used, the hook portion 28 of the anchor pin 27 is accommodated in the accommodation recess 20 and does not protrude upward beyond the accommodation recess 20. Therefore, the single pipe pipe 21 can be installed in the support recess 14 of the base 11 without any trouble, and the anchor pin 27 and the single pipe pipe 21 can be used in combination.

  In addition, the first protrusion 13a and the third protrusion 13c are provided close to the short side surface of the base body 12, and the first protrusion 13a, the second protrusion 13b, and the third protrusion 13c are provided. Are provided close to both long side surfaces of the base body 12. Therefore, when the temporary fence 1 is supported by the base 11, it is possible to avoid the situation where the base 11 protrudes relatively largely outward of the area surrounded by the temporary fence 1 than the temporary fence 1 it can. Therefore, it is possible to prevent a situation where the base 11 becomes an obstacle to a passerby moving outside the area surrounded by the temporary fence 1.
