Description

Steel beam construction safety protection device

technical field

The utility model relates to the field of building construction, in particular to a steel beam construction safety protection device.

Background technique

In the construction of steel structures in construction projects, there are a large number of steel girder structures that need to be hoisted and installed. When the beam is at the edge of the building, workers at the edge are prone to safety accidents such as falling. Generally, protective fences are used for safety protection. However, it is difficult to fix the protective fence and steel beams. Direct welding is time-consuming and laborious, and it will be damaged. Steel beam members.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art and provide a safety protection device for steel beam construction. The device uses a base clamp to fix the column on the I-shaped steel beam, and uses a metal backing plate and an anti-skid rubber pad to limit The uprights move for added safety and prevent construction workers from falling.

In order to solve the above technical problems, the utility model provides a safety protection device for beam construction, which includes at least two parallel columns and at least two steel wire ropes for connecting adjacent columns. The columns are composed of steel pipes, base clamps and at least It consists of two sets of round steel anchors. The steel pipe is welded on the base fixture. The round steel anchor is detachably installed on the steel pipe. The first end of the wire rope is connected with the round steel anchor and fixed at the end with a rope clip. , the second end of the steel wire rope is connected with the turnbuckle bolt, and the turnbuckle bolt is connected with the round steel tie. The base fixture is in the shape of "匚" and is surrounded by the upper top plate, the lower bottom plate and the vertical plate. Two threaded through holes, fastening bolts are arranged in the threaded through holes, a metal backing plate is fixed on the lower surface of the upper top plate, and a threaded counterbore is opened on the metal backing plate, and the threaded counterbore is connected with the threaded through hole of the upper top plate Correspondingly, a non-slip rubber pad is fixed on the upper surface of the lower bottom plate.

When in use, clamp the base clamp on the edge flange of the steel beam, and tighten the fastening bolts. With the tightening of the fastening bolts, the anti-skid rubber pad will move up relatively, and the gap between the anti-skid rubber pad and the steel beam flange will Gradually decrease, the friction force gradually increases, which can firmly fix the base clamp on the steel beam wing, prevent the relative movement between the base clamp and the steel beam, and prevent the column from falling down. Then adjust the turnbuckle bolts to straighten the wire rope to play a role of safety protection. The utility model has small structure and simple installation, better solves the connection problem between the protective fence and the steel beam, eliminates potential safety hazards on site, and can be freely disassembled and reused repeatedly.

Further, the round steel anchor is composed of a sleeve and two symmetrical U-shaped claws welded on the side wall of the sleeve, and two mutually symmetrical threaded holes are opened on the sleeve, and the locking bolts are installed In the threaded hole; there are two symmetrical vertical grooves on the steel pipe, and the end of the locking bolt is against the vertical grooves. When installing, put the sleeve on the steel pipe at a suitable position, and then tighten and lock it Bolt, so that the end of the locking bolt is firmly against the bottom wall of the vertical groove. This detachable structure not only expands the scope of use of the column, but also can remove the wire rope and apply the column to other fields. According to the protection needs, several steel wire ropes are arranged on the same column to reduce the distance between the steel wire ropes and improve the protection effect.

detailed description

Below by accompanying drawing and specific embodiment, utility model is described further. The specific embodiments described here are only used to explain the utility model, and are not intended to limit the protection scope of the utility model.

The safety protection device for steel beam construction, as shown in Figures 1 to 3, includes uprights 100 parallel to each other and two steel wire ropes 300 for connecting two adjacent uprights 100, uprights 100 are tied by steel pipes 10 and two sets of round steel The steel pipe 10 has two symmetrical vertical grooves 11, the steel pipe 10 is welded on the base fixture 30, and there are four reinforcement plates 12 between the steel pipe 10 and the base fixture 30 for reinforcement; The joint 20 is composed of a sleeve 21 and two symmetrical U-shaped claws 22 welded on the side wall of the sleeve 21. There are also two mutually symmetrical threaded holes on the sleeve 21, and the locking bolt 23 is installed in the threaded holes. Among them, the end of the locking bolt 23 is against the vertical groove 11; the first end of the wire rope 300 goes around the U-shaped claw 22 and is fixed at the end with a rope clamp 400, and the second end of the wire rope 300 is connected with the turnbuckle bolt 200 , the turnbuckle bolt 200 is connected with the round steel anchor 20; the base fixture 30 is in the shape of "匚", surrounded by an upper top plate 31, a lower bottom plate 33 and a vertical plate 32, and two threaded through holes are opened on the upper top plate 31, A fastening bolt 34 is arranged in the threaded through hole, and the length of the fastening bolt 34 is greater than the depth of the threaded through hole. A metal backing plate 35 is fixed on the lower surface of the upper top plate 31, and a threaded counterbore is provided on the metal backing plate 35. The described The threaded counterbore corresponds to the threaded through hole of the upper top plate 31, and a non-slip rubber pad 36 is fixed on the upper surface of the lower bottom plate 33.

During use, the base clamp 30 is clamped on the edge flange M of the steel beam, and the fastening bolt 34 is tightened. As the fastening bolt 34 is tightened, the anti-skid rubber pad 36 moves upward relatively, and the anti-skid rubber pad 36 and the steel beam The gap between the wing plates M gradually decreases, and the frictional force gradually increases, which can firmly fix the base fixture 30 on the steel beam wing plate M, prevent relative movement between the base fixture 30 and the steel beam wing plate M, and prevent The upright column 100 falls down, as described in Figures 4-6. After the upright column 100 is installed, adjust the turnbuckle bolt 200 to straighten the steel wire rope 300, which plays a role of safety protection. The utility model has small structure and simple installation, better solves the connection problem between the protective fence and the steel beam, eliminates potential safety hazards on site, and can be freely disassembled and reused repeatedly.

What has been described above is only an embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, some modifications and improvements can also be made without departing from the principle of the utility model, and these should also be Be deemed to belong to the protection scope of the present utility model.
