Description

[Detailed explanation of the idea] Currently, at construction work sites, the work area is surrounded by protective plates, nets, etc., and simple opening/closing doors ( A gate (hereinafter referred to as a gate) has been installed. The actual situation is that the width of the gate is the same depending on the work location or scale of work, so when installing the gate,
There is an inconvenience that the beam must be manufactured to match the width of the entrance/exit each time. The gate materials currently in use are fixed by directly bolting the beams to the pillars, so it is necessary to prepare gate materials with several different beam lengths, and at the work site A. Considering the reality that it is not necessarily possible that the gate materials used can be used directly at the work site of B, the reality is that there are various inconveniences in the gate installation work, as well as the disadvantage of wasting materials. be.

The inventor did not directly fix the beam to the support by bolting, but instead positioned the beam freely according to the width of the support, and if the width of the entrance was extremely wide, the beam could be joined. The purpose is to provide gate materials that save materials and facilitate work by making the gate materials used at work site A usable directly at work site B.

Next, the structure will be explained in detail based on the drawings.

(A) A slide box 2 having a U-shaped cross section is constructed with appropriate length and width on the top side of the column 1, and is welded and fixed to the column 1 with the opening facing down.

(B) Insert the leg of the suspension wheel 3 into the center of one side of the metal column with a □-shaped cross section, form a groove 4 that allows it to move freely from side to side, and insert it into the slide rail 5.
shall be.

The center part of one side of the beam 6 that is inserted into the slide box 2 of the support column 1 on both sides is parallel to the center part of the side of the slide rail 5 on the opposite side of the groove 4,
It is welded and fixed via the spacer fitting 7.

(C) Insert the beam 6 and slide rail 5 integrally formed from below the slide boxes 2 of the pillars 1 on both sides with the slide rails 5 facing downward,
Bolts 8 are passed through the side wall of the slide box 2 on the support 1 side from the outside of the support 1 so that the bottom side of the beam 6 is supported at a position where the upper side of the beam 6 is fully in contact with the upper inner wall of the slide box 2. The lower side of the beam 6 is supported and passed through so that it faces the opposite side wall of the slide box 2, and the beam 6 is fixed to the support 1 by tightening with a nut.

(D) The suspension wheel 3 is designed to be able to be inserted into the slide rail 5, the leg of the suspension wheel 3 penetrates the groove 4 and projects downward, and the lower end of the leg is an L-shaped stopper with a running rod 9 suspended therefrom. The upper side of 10 is clamped with a nut, one end of the running rod 9 is screwed 12 to the tip of the vertical side of the other end, and a gold ring 11 is welded to the other end. After the work is completed, a wire rope is passed through it and both sides are secured. It is tensilely tied to the leg of the support column 1, and the running rod 9 is gripped at the top and bottom.

(E) The suspension wheel 3 with the running rod 9 attached is inserted through the opening of the slide rail 5, a sheet is pasted between the running rods 9, and the passage can be opened by pulling left and right or to one side from the center of the gate. Do as you like.

This is the structure above. Next, examples will be described in detail.

Once the location of the gate is determined at the construction site,
A concrete seat is provided at the location where the pillar 1 is to be erected, and the slide box 2 provided on the top side of the pillar 1 is erected with an anchor bolt on the outside (road side), and the distance between the beam 6 and the slide rail 5 is maintained. With the slide rail 5 facing downward, the beam 6 is inserted from below the slide box 2 of the support 1 on both sides, and the bolt 8 is inserted into the support of the slide box 2 from the outside of the support 1. Pass through the side wall on one side, pass through the lower side of the beam 6, face the side wall on the opposite side, and tighten and fix with a nut. Running rod 9 on hanging wheel 3
Insert the hanging wheel 3 from the opening of the slide rail 5 with the running rod 9 facing down, and
When opening the gate, move the running rod 9 to the left and right from the center, or pull it to one side to open the passage, and when closing the gate, move the running rod 9 from both sides to the center. Either move the rod 9, or if it is pulled to one side, move the running rod 9 to the other side. After the work is completed, wire rope is passed through the ring 11 at the lower end of the running rod 9 and both ends are tied to the support 1 by tension.

As described above, according to the present invention, (a) If the height of the pillar is 4m50 and the length is about 7m30, it can be used at most construction sites and the production cost is very low. becomes.

(b) If the distance between the pillars is less than 7m30, the beams can be attached to the slide box by protruding to the left and right.
There is no need to cut beams, and the height is 4m50.
Because of this, vehicles carrying materials in and out can easily pass through, and the projecting beams on the left and right sides of the top have no bearing on the work.

(c) The running rod is connected at the top by a hanging wheel and at the bottom by a metal ring, so it is perfect as it can withstand wind pressure.

(d) The gate of the present invention can be used at workplace B immediately after the use of workplace A is finished.
There is no need to prepare a large number of different gate materials between gate openings.

It has various advantages as mentioned above.
