Abstract

The utility model provides a regularization elevator entrance to a cave faces limit protector, faces limit protector including the entrance to a cave, and surrounds the U-shaped component of elevartor shaft wall body end, the first parallel limit of U-shaped component with the entrance to a cave faces limit protector fixed connection, and the second parallel limit has the screw, install the nut that passes the screw on the screw. Adopt regularization elevator entrance to a cave face limit protector, fix the guard plate at the elevartor shaft outer wall temporarily through the bolt extrusion, need not to go into the wall body with the bolt nail when playing the guard action, do not have the destruction to the wall body, increased the shaping quality, the installation is dismantled conveniently moreover, saves artifically, reduce cost has improved work efficiency.

Description

Edge protection device for shaped elevator entrance

Technical Field

The utility model belongs to the building field relates to the construction protection technology, concretely relates to regularization elevator entrance to a cave faces limit protection device.

Background

In the construction of high-rise buildings, an elevator shaft is an early finished project, after the construction of the elevator shaft is finished, when construction equipment and materials are carried by the elevator shaft in the construction and decoration process, temporary shielding protection is needed to be carried out on the wall body of the elevator shaft, materials such as steel pipes, steel bars and the like are prevented from falling through the elevator opening, personnel are prevented from falling due to insufficient conditions, and avoids damaging the wall body in the carrying process, the elevator shaft protection in the prior art adopts expansion screws which penetrate through the protection plate and are nailed on the wall body, the screws must be inserted into the wall body, has certain destructive effect on the wall body of the elevator shaft, is not beneficial to the subsequent elevator shaft external assembly operation, because the protective railing falls on the ground at first, so need raise it to the terrace elevation when the terrace stage, expansion bolts need beat again, and it can also cause the secondary damage to the elevartor shaft to extract the screw in the dismantlement process, damages wall body and troublesome poeration.

SUMMERY OF THE UTILITY MODEL

For overcoming the technical defect that prior art exists, the utility model discloses a regularization elevator entrance to a cave faces limit protector.

Stereotyped elevator entrance to a cave faces limit protector, face the limit including the entrance to a cave and prevent the backplate, and surround the U-shaped component of elevartor shaft wall body end, the first parallel limit of U-shaped component with the entrance to a cave faces limit and prevents backplate fixed connection, and the second parallel limit has the screw, install the bolt that passes the screw on the screw.

Specifically, the second parallel edge is welded with a nut.

Preferably, the corners of the U-shaped member are right angles.

Specifically, the U-shaped member is a steel bar.

Adopt regularization elevator entrance to a cave face limit protector, fix the guard plate at the elevartor shaft outer wall temporarily through the bolt extrusion, need not to go into the wall body with the bolt nail when playing the guard action, do not have the destruction to the wall body, increased the shaping quality, the installation is dismantled conveniently moreover, saves artifically, reduce cost has improved work efficiency.

Drawings

Fig. 1 is a schematic view of a specific embodiment of the shaped elevator entrance edge protection device of the present invention;

the reference numbers in the figures refer to: 1-an end of an elevator shaft wall, 2-U-shaped members, 3-a hole edge protection plate, 4-bolts and 5-screw holes.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

Stereotyped elevator entrance to a cave faces limit protector, face the limit backplate including the entrance to a cave, and surround U-shaped component 2 of elevartor shaft wall body end 1, the first parallel limit of U-shaped component with the entrance to a cave faces 3 fixed connection of limit backplate, and the second parallel limit has screw 5, install the bolt 4 that passes the screw on the screw.

The utility model is used for elevartor shaft temporary protection in the work progress, as shown in fig. 1, elevator entrance to a cave both sides have the wall body that stretches out in the work progress, in the construction decoration process, when utilizing elevator shaft transport construction equipment and material, need shelter from the protection to the elevartor shaft wall body temporarily, prevent that materials such as steel pipe reinforcing bar from dropping and preventing personnel from losing sufficient and dropping through the elevator entrance to avoid damaging the wall body in the handling.

Install during facing limit protector, can earlier regard as the steel sheet welding that faces the limit protector on U-shaped member 2's first parallel limit, then with U-shaped member 2 shown the card in figure 1 on the wall body port, first parallel limit and second parallel limit are located two parallel walls of wall body respectively, pass the screw with the bolt afterwards, precession bolt 4 makes the bolt push up tightly on the wall body wall inwards, utilize the bolt to fix whole protector on the wall body.

The U-shaped member is typically formed by bending steel bar at the site and the threaded hole may be formed by welding a nut to the end of the second parallel edge. The corners of the U-shaped members are generally complete into right angles, and the U-shaped members can be tightly attached to the ends of the wall body, so that the phenomenon that the bent parts extend outwards to cause the elevator opening to be blocked by the bent parts is avoided.

Specifically, the second parallel edge is welded with a nut.

Preferably, the corners of the U-shaped member are right angles.

Specifically, the U-shaped member is a steel bar.

In the foregoing, the preferred embodiments of the present invention, if not obviously contradictory or based on a certain preferred embodiment, can be combined and used by any superposition, the specific parameters in the embodiments and examples are only for clearly expressing the utility model verification process of the utility model, and are not used for limiting the patent protection scope of the present invention, the patent protection scope of the present invention is still based on the claims, and all the equivalent structural changes made by the contents of the specification and the drawings of the present invention should be included in the protection scope of the present invention.
