Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mounting stand for a gate-shaped barricade for a construction site.

[Prior Art] Conventional barricades for construction sites are constructed by fixing the lower part of the leg frame rod forming an inverted V shape with a connecting rod, or fixing the lower part of the leg frame rod forming an inverted V shape with an upper frame between the upper ends of the left and right leg frames which are foldable. Commonly called A-type barricades connected by rods, and gate-type barricades in which pipes are formed into a substantially inverted U-shape are used.

[Problems to be solved by the invention] However, the A-type barricade has bulky leg frame rods, making it inconvenient to transport and move, and is unstable against shocks and wind pressure caused by contact and vibration during use. in,
It is easy to shift from the installed position or fall over, so in order to prevent this, it is necessary to bind the legs with a single pipe and wire, or use weights such as burr stones or sandbags filled with sand. Foldable devices have had problems such as if the tip of the device is stepped on by a car or the like, it becomes impossible to fold and has to be discarded. In addition, with gate-type barricades, a support such as a stake is erected at the installation location, and the left and right leg rods are tied and fixed to this with wire, etc., but it is troublesome to install and remove, and the fixed state is not stable. There were problems such as stability and weakness against external forces.

In order to solve these problems,
There is a technique published in Publication No. 58615.

This publication discloses that a pair of partition plates projecting upward from the frame are disposed within a short cylindrical frame at a certain distance from opposing side walls of the frame, and the partition plates and the side walls A stand for a barricade, in which a guide groove for inserting and supporting a barricade pillar with little rattling is formed between the partition plates, and a bar serving as a handle and reinforcing rod is provided between the opposing partition plates. is disclosed.

However, the stand for this kind of barricade is
Even if the barricade pillars are inserted and supported with little rattling, the short cylindrical frame will rotate if an external force such as vibration, impact or wind pressure is applied because it can tilt in a specific direction. You will move and fall. In addition, the number of parts is large and it cannot be manufactured at a low cost. Further, although the directionality of the external force can be almost determined, it is not possible to deal with the directionality because the short cylindrical frame is square or cylindrical.

Therefore, the object of the present invention is to provide a mounting stand for gate-type barricades for construction sites that can stably stand up the gate-type barricade against external forces and can be manufactured at low cost by reducing the number of parts. It is.

[Means for Solving the Problems] The mounting stand for the gate-type barricade for construction sites according to the present invention has an approximately rectangular parallelepiped shape with one side longer than the other side of the lower surface of the outside, and the inside of the stand main body is hollow. A hollow portion that is continuously opened to the top and bottom surfaces, a plurality of insertion holes provided at the corners of the stand main body so that the leg rods of the gate-shaped barricade can be inserted vertically, and the overlapping of the stand main body. an upper surface periphery having a predetermined wall thickness that allows a narrow opening area on the upper surface; a protrusion formed on the upper side of the upper surface periphery of the base body; and a protrusion formed on the lower surface side of the base body; and a fitting portion that fits together so that the stand bodies do not move in a direction perpendicular to the stacking direction when the stand bodies are stacked together.

[Function] In the present invention, the entire body is made of casting, and the outer shape is a substantially rectangular parallelepiped, and the legs of the gate-shaped barricade are inserted into the plurality of insertion holes provided at the corners of the body. It is installed by inserting a rod vertically. Therefore, since the approximately rectangular parallelepiped stand body is long in the horizontal direction when placed, a large couple acts on the inclination of the leg rods of the gate-type barricade, causing the leg rods of the gate-type barricade to stand vertically. This state is maintained stably.

Further, the protrusion formed on the upper side of the upper peripheral edge of the stand body and the fitting part formed on the lower side of the stand body are overlapped, so that the stand bodies are perpendicular to the stacking direction. Since it is designed so that it does not move in any direction, it will not easily fall over even if a large number of stacks are stacked. Furthermore, since the upper surface periphery has a predetermined wall thickness that allows the base bodies to be overlapped and the opening area of the upper surface is narrowed, the overlapping area is wide and stable stacking is possible.

The stand main body 1 is entirely made of cast metal, and its outer shape is a substantially rectangular parallelepiped in which one side of the lower surface is longer than the other side, as shown in FIGS. 1 and 2 in the mounted state. That is, the stand main body 1 when the present invention is implemented is:
It is sufficient that the entire device is made of a cast metal, and its outer shape is a substantially rectangular parallelepiped that is elongated in the lateral direction, as shown in FIGS. 1 and 2 in the placed state. It is desirable that the cast iron stand body 1 has an appropriate weight of about 7 kg.

This truncated pyramidal base body 1 has a hollow interior and a hollow portion 2 that is continuously open to the upper and lower surfaces. That is, the upper and lower surfaces of the stand main body 1 are continuously opened by the hollow portion 2. An insertion part 3 that bulges into the hollow part 2 is provided at each corner of the base body 1, and an insertion hole 5 is formed in the center of the insertion part 3. This insertion hole 5 is formed into a cylindrical shape so that the leg rod 4 of the gate-shaped barricade B can be inserted in the vertical direction and the inclination of the leg rod 4 can be restricted. That is, this insertion hole 5 penetrates in the vertical direction, and is inserted into the leg rod 4 of the gate-shaped barricade B.
The leg rod insertion hole is slightly larger in diameter than the main part.

An upper surface peripheral portion 7 is formed on the upper surface of the table main body 1 to have a predetermined thickness and narrow the area of the upper surface. This upper surface peripheral portion 7 allows multiple overlapping. Furthermore, a protrusion 8 is formed at the upper part of the upper peripheral edge 7 of the table main body 1 so as to protrude toward the upper side of the upper peripheral edge 7. The protrusion 8 provided on the upper peripheral edge 7 of the stand main body 1
A fitting portion is provided on the lower surface side of the holder to prevent the pedestal bodies 1 from moving in a direction perpendicular to the stacking direction (horizontally when placed) when another pedestal body 1 is stacked on top of the other pedestal bodies 1. 6 is formed. That is, the spacing between the fitting parts 3 on the shorter sides of the base body 1 in the lateral direction allows them to be fitted with the projections 8 provided on the upper peripheral edge 7 of the base body 1. It is formed on the lower surface side of the main body 1 to prevent the stand main bodies 1 from moving in the direction perpendicular to the stacking direction when the stand main bodies 1 are overlapped.

As described above, the stand A of this embodiment is made entirely of cast iron, and has a stand main body 1 whose outer shape is a substantially rectangular parallelepiped that is long in the horizontal direction when placed on it, and a hollow interior of the stand main body 1.

There is.

Next, a case will be described in which the stand for the gate-type barricade for construction sites of this embodiment is used.

FIG. 3 shows a basic form in which one gate-type barricade B is installed using the installation stand for the gate-type barricade for construction sites according to this embodiment.

Corresponding to the dimensions between the left and right leg rods 4 of the gate-shaped barricade B, place the stand A in parallel on the ground, and insert the lower part of the leg rod 4 into the insertion hole 5 on the road L side of the stand A. The gate-shaped barricade B is installed vertically between the mounting bases A.

Also, depending on the situation at the barricade installation site,
Any fitting hole 5 other than the former may be used.

FIG. 6 shows a case where a plurality of gate-shaped barricades B are installed in parallel in the horizontal direction.

A required number of mounting stands A are arranged in one row in the horizontal direction at required intervals, and the lower part of each leg rod 4 of the gate-shaped barricade B is inserted into each insertion hole facing each other on the road L side of the adjacent mounting stands A. 5 and install barricade rows that continue in a straight line in the horizontal direction.

FIG. 7 shows a case where the barricade rows are continuously installed in a bent state.

A required number of mounting stands A were arranged along the barricade installation direction at predetermined intervals, and the leg rods 4 of the gate-shaped barricade B were inserted and bent into the opposing insertion holes 5 of adjacent mounting stands A. Gate-shaped barricades B are installed continuously in the state.

In addition, when transporting the mounting base of the present invention to a construction site or storing it when not in use, the mounting bases A are stacked upward one after another as shown in Fig. 4, and the mounting bases A are installed on the upper peripheral edge 7 of the lower stage A. The outer surface 9 of the protrusion 8 is brought into contact with the inner wall surface 10 of the lower end of the hollow part 2 of the upper stage A,
Or, fit close together. This prevents horizontal displacement between the upper and lower stacked stands A and the collapse of the load.

As described above, the installation stand for the gate-type barricade for construction sites according to the embodiment of the present invention is made entirely of cast metal, and has a stand main body 1 with an approximately rectangular external shape, and the corner corners of the stand main body 1 are A plurality of insertion holes 5 provided in
The leg rods 4 of the gate-shaped barricade B are inserted vertically into the barricade B to be erected. Therefore, since the substantially rectangular parallelepiped platform main body 1 is long in the horizontal direction when placed, a large couple acts on the inclination of the leg rods 4 of the gate-shaped barricade B, causing the leg rods 4 of the gate-shaped barricade B to tilt. The vertically installed state is stably maintained.

Further, the protrusion 8 formed on the upper side of the upper peripheral edge 7 of the stand main body 1 and the fitting part 6 formed on the lower side of the stand main body 1 are overlapped, so that the stand main body 1 is mutually connected. Since it is designed not to move in the direction perpendicular to the stacking direction, it will not easily fall over even if the number of stacks is increased. Further, since the upper surface peripheral portion 7 has a predetermined wall thickness that allows the base bodies 1 to be stacked together and has a narrow opening area on the upper surface, the overlapping area is wide and stable stacking is possible.

In this way, the installation stand A of the gate-type barricade for construction sites of this embodiment has a simple structure, is easy to handle, and has an appropriate weight (approximately 7 kg).
Because of this, it can be placed stably on the ground, and if the gate type barricade B is attached and installed at a construction site, the gate type barricade B may fall over due to external forces such as vibration, shock, wind pressure, etc. Since the gate-type barricade B does not shift, it eliminates the trouble of using weights such as burrstones or sandbags as with the conventional gate-type barricade B, and greatly saves labor and time during the installation work of the gate-type barricade B. .

Furthermore, since they can be stacked for transportation when moving to a construction site or for storage when not in use, they do not take up much space, and the upper and lower tiers A are held by protrusions 8 to prevent shifting or collapse of the load. Prevented.

Furthermore, when the gate-type barricade B is installed using the installation stand A of the gate-type barricade for construction sites of this embodiment, the width occupied by the road and the protrusion toward the road side are smaller than the conventional gate-type barricade B. This has excellent practical effects, such as being able to minimize obstacles to traffic, and also making it possible to keep the barricade rows orderly when installing continuous gate-shaped barricades.

[Effects of the invention] As described above, the installation stand for the gate-type barricade for construction sites of the invention is made entirely of cast metal, and has a stand body with an approximately rectangular external shape, and the corners of the stand body are The leg rods of the gate-shaped barricade are vertically inserted into a plurality of insertion holes provided at the corners to stand upright.

Therefore, since the stand body is long in a specific direction when placed, a large couple acts on the inclination of the leg rods of the gate type barricade, causing the leg rods of the gate type barricade to stand vertically. is maintained stably. Moreover, especially when the outward direction is separated, it is sufficient to align the long direction in the lateral direction with the stand main body in the placed state.

Therefore, since it can be formed integrally by casting, the structure is simple and easy to handle, and it has a suitable weight, so it can be placed stably on the ground, and a gate-shaped barricade can be attached.
When installed at a construction site, the gate-type barricade will not fall over or shift its installation position due to external forces such as vibrations, shocks, or wind pressure, so it cannot be used with burrstones, sandbags, etc. like conventional gate-type barricades. This eliminates the trouble of using weights, and greatly reduces the labor and time required for installing Varistone.

Further, the protrusion formed on the upper side of the upper peripheral edge of the stand body and the fitting part formed on the lower side of the stand body are overlapped, so that the stand bodies are perpendicular to the stacking direction. Since it is designed not to move in any direction, it will not easily fall over even if a large number of stacks are stacked. Furthermore, since the upper surface periphery has a predetermined wall thickness that allows the base bodies to be overlapped and the opening area of the upper surface is narrowed, the overlapping area is wide and stable stacking is possible.

Therefore, it does not take up much space when transporting to a construction site or storing when it is inconvenient because it can be stacked, and the upper and lower holders are formed on the upper side of the upper periphery of the main body. A projection part and a fitting part formed on the lower surface side of the stand body and fitted together so that the stand bodies do not move in a direction perpendicular to the stacking direction when the stand bodies are overlapped. This prevents the load from shifting or collapsing.

Furthermore, when a gate-type barricade is installed, it occupies less road width and protrudes toward the road than a conventional gate-type barricade, minimizing obstruction to traffic, and it is possible to install a continuous gate-type barricade. This has excellent effects such as making the barricade rows orderly.
