Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a post fixing device for an assembly gate.

(Prior Art) Conventionally, this type of assembled gate has had an integral structure including a foundation part buried underground, a roof built on the foundation part, and a gate post part of a pillar. For this reason, during transportation and packaging,
It required a lot of effort and careful transportation. Also, because of this integral structure, skilled skills were required to maintain balance between the supports and level them with the ground surface during installation. Therefore, it has become common practice to separate the underground foundation and the gatepost structure built thereon into two parts, as disclosed in Japanese Utility Model Application Publication No. 53-75930. However, the foundation that supports the gateposts, which are divided and therefore subject to considerable weight, requires splints such as buttresses (reinforcing braces), which requires unnecessary work and space for installing the buttresses. did.

(Problems that the invention aims to solve) Since this type of gate is symbolically located at the front of the house, construction work can be done in a short time, and there should be no unnecessary features around the gateposts. Furthermore, it is necessary to easily prevent corrosion of the buried foundation.

(Means for solving the problem) The pillar fixing device, which is the foundation of the gate according to the present invention, is composed of an auxiliary formwork 2, a connecting plate 4 for fixing the side of the pillar, and a base 1. More specifically, the left and right pillars 10 supporting the gate,
In a foundation structure in which the lower part of the frame 10 is horizontally supported and buried, a plurality of bolt holes 41 are pre-drilled on the outside of the auxiliary formwork 2, which is arranged parallel to the front and back direction facing the front of the gate. The connecting plate 4 is erected vertically upward, and a base 1 having an E-shaped cross section on which the lower end surface of the support column 10 is placed inside is provided, so that the auxiliary formwork 2, the connecting plate 4, and the base 1 are connected to each other. A pair of fixtures A, A, which are fixed integrally and have a substantially inverted T-shape in appearance, receive the lower part of each pillar, and connect the outer surface of the lower part of the pillar with a connecting plate 4 interposed therebetween. This is a column fixing device that is characterized in that it is used by connecting and fixing it.

(Example) The pillar fixing device A disclosed in the present invention consists of an auxiliary formwork 2 made of steel material with a C-shaped cross section, a belt-shaped connecting plate 4 for the pillar in which a plurality of bolt holes 41 are pre-drilled, and an E-shaped cross-section. This fixture A consists of a base 1 and is welded in a substantially inverted T-shape as a whole.

As disclosed in the section of the above-mentioned constituent means, the fixing devices A and A are placed opposite each other so that the lower part of each column is placed horizontally on the base, and the connecting plate is placed along the lower outer surface of the column. 4 through the bolt 51
After tightening, the entire gate G is safely fixed and used.

Therefore, the auxiliary formwork 2 must be installed in advance at the gate installation site.
Until the groove of dimension 1 and the height of the base 1 are buried,
Keep digging. If the area is soft, it is a good idea to pour concrete or other material into the trench to solidify the ground.

Next, the foundation fixing device constructed as described above is driven and fixed at a predetermined position within the excavation using anchor bolts or the like. Of course, they are fixed parallel to each other and horizontally at appropriate intervals depending on the width of the gateposts.

Then, place the left and right pillars 10, 10 of the gate G on the base 1.
Each column is mounted horizontally on the column receiving portion 1a of the column, and is connected to each column using a plurality of fastening bolts 51, 51 via a connecting plate 4 that protrudes from the auxiliary formwork 2 along the lower outer surface of each column. Link.

The foundation of the gate installed in this way is buried and hardened with concrete or the like up to the top surface of the base.

On the other hand, depending on the weight of the gate or the ground of the installation location, the contact portion between the auxiliary formwork 2 and the supporting column connecting plate 4 may be further reinforced by welding with a reinforcing connecting plate 3.

In such assembly gates, a wall W such as an earthen wall or block wall is often installed continuously on the left and right outer sides of the support, and the close contact between the support and the fence may cause them to separate over a long period of time and create a gap. It is something that occurs. However, if a construction method is adopted in which the head of the bolt fastened to the connecting plate 4 is slightly protruded outward (in the direction of the wall) and installed in the wall, for example, concrete is hardened, gaps can be prevented. . If you use a special fastener with the head of this bolt shaped like a key, you will be able to completely prevent gaps.

(Effects) With this kind of configuration, both the main body of the gatepost and the base (fixing device) can be manufactured in the factory, so
It is also easy to transport and pack. Additionally, installation work can be completed in a short time. In addition,
If the foundation is made of steel, there is less worry about corrosion, and all you need to do is apply preventative treatment to the bottom of the gateposts each time using insect repellent. Furthermore, the connection between the gate and the fence can be maintained in an airtight state using a plurality of fastening bolts that also serve as support connecting plates.

Assembled gates using this post fixing device do not require reinforcements for gates such as buttresses, and are extremely stable, even in narrow site spaces or entrances with stairs or slopes. This has the advantage that the construction of the assembled gate can be carried out with
