Description

[Detailed description of the invention]

0001

[Industrial Application Field] When constructing a building structure, the present invention performs the work of sequentially forming structural units for each floor starting from the top floor, and the work of connecting structural units formed previously, on the ground. The present invention relates to a method of constructing a building structure and a method of connecting column members, which eliminates the need for installation of work scaffolding or protective nets, by simultaneously pushing up the formed structural unit vertically upward.

0002

[Background Art] In recent years, with the economic development of society, commercial functions have been concentrated in urban areas, leading to soaring underground prices, and the social situation has become such that even narrow land with narrow frontage has to be used effectively. Architectural structures such as office buildings and multi-level parking lots are being constructed on such land. Conventionally, when constructing such a building structure, a mobile crane is used to assemble a small span into a staircase shape, and the construction is proceeded by receding. A horizontal stacking method is used in which each block is stacked over the entire surface. In both of the above methods, only the framework is built by sequentially stacking multiple column members, beam members, braces, etc. from the lower floor to the upper floor, and then the wall members are attached and finishing work such as painting is performed. This is a construction method that performs the work. Since the above construction method is used, it is important to ensure that people can move to the installation location of wall components or finishing work such as painting, and to perform the work efficiently, and to ensure the safety of the work. In order to ensure safety, it is essential to install sturdy work scaffolding around the entire perimeter of buildings or at appropriate locations, as well as protective nets to prevent accidents caused by falling construction materials.

0003

However, in the above-mentioned prior art, a large number of skilled workers must be engaged in setting up the work scaffolding and protective net, which requires a great deal of labor and construction cost, and The construction period to complete the structure will be longer. In addition, it is necessary to secure space for installing work scaffolding on a narrow site with a narrow frontage, and it is necessary to place lifting equipment such as a tower crane or mobile crane within or around the site. This was a difficult problem during construction.

The present invention has been devised in view of the above-mentioned circumstances, and it is possible to form a structural unit for each floor by carrying out on the ground, from constructing the frame to finishing work such as installing and painting wall members. At the same time as completion, connection with previously formed structural units shall also be carried out on the ground. Furthermore, it is an object of the present invention to provide a construction method in which the structural units are sequentially formed starting from the structural unit for the top floor, and the formed structural units are pushed vertically upward.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the following solutions are taken by the present invention. In the invention of claim (1), a pushing means for pushing up the formed structural unit vertically upward is disposed near the foundation, and for the structural unit formed subsequently, the column member is made to stand upright directly above the foundation. After that, the pillar members of the previously formed structural unit are connected with the column members that make up the column parts, and then the formation is carried out. Once the formation of the structural unit is completed, the column members are laid horizontally and transported into the building site. Construction is carried out by pushing the formed structural unit vertically upward as much as possible. Specifically, step 1 involves vertically arranging a plurality of lifting means at appropriate intervals near the foundation installation position, and step 1 of vertically arranging a plurality of lifting means at appropriate intervals in the vicinity of the foundation installation position, and
After each column member is made to stand upright directly above the foundation, the beam member is connected to the A-column member, other beam members, or brace members to construct a frame, and then the wall members are attached to the frame. Step 2 of performing finishing work such as painting to form a structural unit for the top floor, and activating the pushing means to press the structural unit for the top floor vertically upward to form the next structural unit. A step 3 of pushing up the top floor structural unit vertically upward as much as possible by horizontally installing a plurality of B column members each having a length of one section on the site; After each column member is laid horizontally on the site, the B column member is pulled up to stand upright on each of the plurality of foundations, and after being connected to the A column member, the beam member is placed on the B column member.
Step 4 of constructing a frame by joining with column members, other beam members, or bracing members, and then attaching wall members to the frame, and then performing finishing work such as painting to form a structural unit for the next floor. Thereafter, if necessary, steps 3 and 4 are repeated to form the structural units for each floor sequentially from the upper floor until the formation of the structural unit for the lowest floor is completed, and step 5 is performed. The building structure is constructed using a construction procedure consisting of Step 6, in which the column members constituting the structural unit are fixed on the foundation.

In the invention of claim (2), a commonly used cylinder is employed as the pushing up means, and after the previously formed structural unit is pushed up to a certain height by the cylinder, the structural unit is lifted up. While being supported by the receiving member, the cylinder is moved away from the pushing up action position and the pushing up action is temporarily interrupted. After that, the cylinder is used to push up the structural unit formed later to a certain height again, and this process is repeated thereafter, making it possible to construct a building structure of considerable height even with a cylinder whose stroke is not long. This is what was done. Specifically, step 1 involves vertically arranging a plurality of push-up cylinders at appropriate intervals near the foundation installation position, and each of a plurality of A-column members each having a length of one section is made to stand upright directly above the foundation. After that, the beam members are connected to the A-column members, other beam members, or bracing members to construct a frame, and then, after attaching the wall members to the frame, finishing work such as painting is performed to complete the construction for the top floor. Step 2 of forming a structural unit; activating the push-up cylinder to press the top floor structural unit vertically upward; forming a plurality of joint lengths constituting the column parts of the structural unit to be formed next; Step 3 of pushing the top floor structural unit vertically upward as far as the B pillar members can be horizontally installed on the site.
After each of the above-mentioned plurality of one-section length B-column members is laid horizontally on the site, the B-column members are pulled up to stand upright directly above each of the plurality of foundations, and connected to the A-column members. After that, the beam members are connected to the B column members, other beam members, or bracing members to construct a frame, and then, after attaching the wall members to the frame, finishing work such as painting is performed to prepare for the next floor. Step 4 of forming a structural unit;
The push-up cylinder is operated again, and the structural unit for the top floor is further pressed in the vertically upward direction, so that a plurality of column members each having a length of one section constituting the column member of the structural unit for the third floor from the top, Step 5 of pushing up the top floor structural unit and the next floor structural unit vertically upward as far as they can be horizontally installed on the site, and supporting the beam members constituting the next floor structural unit with receiving members, and then , step 6 of temporarily interrupting the pushing up action of the pushing up cylinder, and setting the pushing up action position to the lower position;
Step 7 restarts the pushing up operation for the top floor structural unit and the next floor structural unit, and constructs the frame, installs wall members, and performs finishing work such as painting in the same manner as described above, and 3 from the top
step 8 to complete the formation of the structural unit for the lowest floor, and then, if necessary, repeat steps 5 through 8 for each floor until the formation of the structural unit for the lowest floor is completed. It was decided that the building structure would be constructed using a construction procedure consisting of Step 9, in which structural units are sequentially formed starting from the upper floor, and Step 10, in which column members constituting the structural units for the lowest floor are fixed on the foundation. It is something.

In the invention of claim (3), the lifting means causes the column member to stand upright on the foundation in conjunction with the vertical upward movement of the previously formed structural unit. This facilitates connection with the pillar members that are the constituent members of the structural unit formed by the above construction. Specifically, step 1 involves horizontally installing the B pillar member at a position below the previously formed structural unit, and then inserting the B guide piece into the B pillar member; A step 2 of inserting another A guide piece into the A pillar member constituting the pillar part of the unit from a direction substantially perpendicular to the axis of the B pillar member under the sliding movement of the pin, and operating the pushing up means to advance the A pillar member. Step 3: By pushing up the structural unit formed by the above vertically upward, the pillar member is gradually moved to the foundation installation position while standing up under the tension guidance of the pin, and finally stands upright directly above the foundation. , by retracting the push-up means and lowering the pillar member slightly vertically downward under the guidance of the pin,
After bringing the A pillar member and the B pillar member closer to each other, the pillar members are connected to each other by a step 4 of connecting the A pillar member and the B pillar member by tightening means such as bolts. It was decided that they would be connected.

[0008]

[Operation] The operation of the present invention with the above structure is as follows. According to the invention of claim (1), a plurality of push-up means are arranged at appropriate intervals in the vicinity of the foundation. next,
After each of the A-column members each having a plurality of lengths, each of which will be the column part of the structural unit for the top floor to be formed, is stood upright directly above the foundation, the beam members are attached to the A-column members, other beam members, or After joining with the bracing members to construct a frame and then attaching wall members to the frame, finishing work such as painting is performed to complete the work of forming the top floor structural unit on the ground. Then, the pushing up means is activated to push the top floor structural unit vertically upward and push it up slightly. Then, a slight space will be created between the site and the lower part of the structural unit for the top floor, so in that space, a plurality of B-column members with a length of one section are installed, which will become the column parts of the structural unit for the next floor that will be formed next. It must be installed horizontally. Thereafter, under the operation of the pushing up means, the top floor structural unit is further pushed up to a height at which the top floor structural unit and the next floor structural unit can be connected vertically upward. Then, the plurality of B pillar members each having one section length are pulled up and made to stand upright directly above each of the plurality of foundations. Thereafter, the construction and finishing work of the frame is carried out in the same manner as described above to complete the work of forming the structural unit for the next floor on the ground and the connection with the structural unit for the top floor. Next, after repeating the same steps as described above to form structural units for each floor from the upper floor to the lowest floor in sequence, the column members constituting the lowest floor structural unit are fixed on the foundation. , the desired architectural structure will be completed on the site.

According to the invention of claim (2), claim (1)
In the same manner as in the invention, under the operation of the push-up cylinder, the work of forming the structural unit for the top floor is first completed, and then the push-up action of the push-up cylinder is continued to form the structural unit for the top floor and the structure unit for the next floor as much as possible. While further pushing up the top floor structural unit to a height at which the structural unit can be vertically connected to the structural unit, the work of forming the next floor structural unit and the work of connecting this structural unit and the top floor structural unit are performed. complete it. Then, the push-up cylinder is further pushed up, and the top floor structural unit is pushed vertically upwards to push it up a little further. As a result, a small space will be created between the site and the bottom of the structural unit for the next floor, and in that space, the lengths of multiple joints that will become the column parts of the structural unit for the third floor from the top that will be formed next will be created. The third pillar member is installed horizontally. After that, the beam member constituting the structural unit for the next floor is supported by the receiving member, and then the rod of the push-up cylinder is retracted to remove it from the push-up position. The floor structural unit is supported only by the receiving member, and the pushing up operation of the pushing up cylinder is temporarily suspended. Thereafter, with the rod in contact with the member located below the pushing up action position, the pushing up action of the pushing up cylinder is resumed, and the third floor from the top is moved in the same manner as described above. Form a structural unit. and,
If the structural unit for the third floor from the top is not for the bottom floor, repeat the same procedure as described above to sequentially form structural units for each floor from the upper floor to the bottom floor. When the column members that make up the lowest floor structural unit are fixed on the foundation, the desired architectural structure is completed on the site.

[0010] According to the invention of claim (3), after the B pillar member is placed horizontally at a position below the previously formed structural unit, one B guide piece is inserted into the B pillar member. Next, the other A guide piece is inserted into the A pillar member that constitutes the pillar part of the structural unit formed previously, and the other A guide piece is rotated through the B guide piece and the pin. Since they are movably connected, the other pillar member A, which is in a positional relationship substantially perpendicular to the pillar member B, is connected to the other pillar member A.
The guide piece is inserted smoothly. Then, when the pushing-up means is operated to push up the previously formed structural unit vertically upward, a pushing-up force is transmitted to the pillar member via the pin, and the pin is guided in tension. As a result of the action, the pillar member is gradually moved to the foundation installation position while being erected, and finally stands upright directly above the foundation. Thereafter, when the pushing-up means is retracted and the A-post member is slightly lowered, the A-post member and the B-post member come very close to each other under the guidance of the pin. As a result, the mounting holes for tightening means such as bolts drilled in the A column member and the B column member come very close to each other, and the positions of the mounting holes almost coincide, so that the two column members can be easily connected. It will be done.

After installing, as shown in FIG. 4, step 1 is performed in which four lifting means 9 are provided at equal intervals at four locations inside the foundation 7 installation position. Next, as shown in FIG. 1, four first column members 13 each having a length of one section, which will serve as the column parts of the top floor structural unit 11 to be formed first, are made to stand upright directly above the foundation 7. After that, the four first pillar members 13
An upper beam member 1 which also serves as a roof is placed on the top surface 13a of the

Step 2 is then carried out to complete the work of forming the top floor structural unit 11 on the ground as shown in FIG. Next, the four lifting means 9 are operated in synchronization, and the lower surface 16a of the upper beam member 16 is vertically lifted simultaneously and with the same force in order to enable the horizontal installation of the pillar member of one section length on the site 5. By pressing in the direction, step 3 is executed in which the top floor structural unit 11 is pushed up vertically to create some space between the site 5 and the lower part of the top floor structural unit 11. Thereafter, in that space, four second pillar members 21 having a length of one section each constitute a pillar part of the structural unit 19 for the next floor to be formed, and are each provided with a connector for connecting to the first pillar member 13. For example, as shown in FIG. 3, the foundations 7 are installed horizontally on a line 20 between the installation positions of the foundations 7. Then, the pushing up means 9
Under the operation, the lower surface 16a of the upper beam member 16 of the top floor structural unit 11 is pressed vertically upward, so that the top floor structural unit 11 can be connected to the next floor structural unit 19 in the vertical upward direction. Push it up even higher. Then, the four second pillar members 21 each having the same length as described above are connected to the first pillar member 13 via the connector by the arrow 201 shown in FIG.

As a result, the top floor structural unit 11 and the next floor structural unit 19 are supported by the pushing up means 9 in a connected state and are located vertically above the site 5. Then step 3 and step 4
Step 5 is repeated to form the structural units for each floor sequentially starting from the upper floor, and repeatedly forms the structural units 23 until the formation of the structural unit 23 for the lowest floor is completed. Thereafter, the flange portions 26 of the bottom floor column members 25 constituting the column portions of the bottom floor structural unit 23 are fixed onto the four foundations 7 using tightening means such as bolts. When step 6 is executed, the desired architectural structure 1 is completed on the site 5. In addition, in the case where the structural unit for the next floor is a building structure serving as a structural unit for the lowest floor, step 5 is not necessary, and the process moves from step 4 to step 6.

Next, an embodiment of the invention according to claim (2) will be described. FIG. 5 shows the state immediately before the temporary interruption of the pushing-up operation of the pushing-up cylinder to the state in which the pushing-up operation is restarted, and (A) shows the top floor structural unit 11 and the next (B) shows the state immediately before the pushing up operation is temporarily interrupted when the building structure unit 19 is connected and positioned vertically above the site 5. (C) shows a state in which the pushing-up operation has resumed, and FIG. 6 shows the construction procedure of the building structure according to this embodiment. In this example, as the construction of the building structure progresses, the structural units that are directly pushed up by the pushing up means are sequentially changed to structural units for lower floors, and a general cylinder with a relatively short stroke is used. A case will be explained in which it can be used as a pushing up means. (1) In the same manner as in the embodiment of the present invention, steps 1 and 2 for forming the top floor structural unit 11 are executed under the synchronized operation of four push-up cylinders 27, as shown in FIG.

Step 7 of restarting the pushing up operation of the pushing up cylinder 27 is executed with the tip end of the pushing up cylinder 27 in contact with the lower beam member 17 of the top floor structural unit 11. Then, the third column member 33 having the length of one section is pulled up by the second column member 21 via the connector and is made to stand upright directly above each of the four foundations 7. Then,
The second column member 21 and the third column member 33 are connected by connecting the flange portions 22 and 34 of both members using a tightening means such as a bolt. Step 8 is then carried out to complete the formation of the structural unit 31 for the third floor from the top on the ground by constructing the framework, installing wall members, and completing finishing work such as painting in the same manner as described above. do. Next, steps 5 to 8 are repeated until the formation of the structural unit 23 for the lowest floor is completed, and step 9 is executed to sequentially form structural units for each floor starting from the upper floor. After that, when step 10 is performed in which the flange portion 26 of the bottom floor column member 25 constituting the column portion of the bottom floor structural unit 23 is fixed on the foundation 7 using a tightening means such as a bolt, The desired building will be completed on Site 5. Note that in the case where the structural unit 31 for the third floor from the top is a building structure that becomes the structural unit for the lowest floor, step 9
is unnecessary, and the process moves from step 8 to step 10.

Next, an embodiment of the invention according to claim (3) will be explained. FIG. 7 shows the process from the stage when a column member constituting a column part of a structural unit to be formed later is laid horizontally on a site using a guide means, to a structural unit formed in advance. This figure shows the process up to the stage of connecting with the pillar member, and (A) shows the horizontally installed state.

Next, the other A guide piece 39 is inserted into the A pillar member 53, which is a component of the structural unit formed previously, and the A guide piece 39 and the B guide piece 45 are connected as described above. Since they are connected, the other A guide piece 39 described above is smoothly inserted into the hollow hole 54 of the A pillar member 53 which is in a positional relationship substantially perpendicular to the B pillar member 55. Next, as shown in FIG. 2B, when the pushing up means 9 is operated to push up the previously formed structural unit vertically upward, the A pillar member 53 and the pin 51 are sequentially attached to the B pillar member 55. Since the pushing-up force is transmitted through the pillar member 55, the pillar member 55 is gradually moved to the foundation 7 installation position while being erected. Thereafter, when the pushing-up operation of the pushing-up means 9 is further continued, the pillar member 55 is erected directly above the foundation 7, as shown in FIG. 7(c). Then, the pushing up means 9 is retracted, and the pillar member 53
