Problems solved by technology

[0002] According to the "National Building Construction Safety Inspection Standard" JGJ59-2011, two protective railings should be built with steel pipes or moso bamboo around the floors without walls. The existing projects under construction basically use steel pipes for protection, but how about steel pipe protective railings? Fixing, how to make it beautiful has always been the subject of everyone's research. At this stage, the root of the protective railing is often fixed on the concrete floor with expansion screws. Because the expansion needs to be drilled first, and drilling requires machinery and electricity, the cost is high. , the construction is cumbersome and time-consuming, resulting in many units cutting corners and posing potential safety hazards

Embodiment 1

[0017] See figure 1 with figure 2 , The present invention provides an edge hole protection device, including a steel pipe body 1, a protective steel pipe 2 is inserted into the steel pipe body 1, and a locking mechanism for fixing the protective steel pipe 2 is provided on the middle side of the steel pipe body 1. The locking mechanism includes a fixing nut 3 welded to the steel pipe body 1, the screw hole of the fixing nut 3 is communicated with the pipe hole of the steel pipe body 1, and the screw hole of the fixing nut 3 is provided with a locking nut 3 Bolt 4; opposite to the other end of the locking mechanism on the steel pipe body 1 welded with a screw 5, the screw 5 is perpendicular to the steel pipe body 1, and the screw 5 away from the steel pipe body 1 is provided with a lock nut 51.

[0018] In order to make the fixation of the present invention more reliable, it is preferable that the screw 5 in this embodiment is arranged in the middle of the steel pipe body 1, and t...

Embodiment 2

[0022] See figure 2 , Example 2 is an improvement on the method of fixing the protective device on the basis of Example 1.

[0023] In actual use, the entire device is vertically fixed on the screw hole of the shear wall 11, that is, the screw 5 is vertically inserted into the screw hole of the shear wall 11, and the lock nut 51 is used to fix it, and then the steel pipe A protective steel pipe 2 is installed vertically on the body 1, and then fixed by a locking bolt 4. A horizontal protective steel pipe 2 is added between two adjacent protective devices. Finally, a fastener 12 is used to connect the vertical protective steel pipe to the horizontal The protective steel pipe is fixedly connected.

[0024] The invention reduces the construction cost, saves materials, and the protective device has a simple manufacturing method, can be freely disassembled during installation and disassembly, is convenient to operate, greatly improves the efficiency of civilized construction work, and ...

Abstract

The invention discloses a critical edge and cave entrance protective device and a fixing method of the critical edge and cave entrance protective device. The critical edge and cave entrance protective device and the fixing method of the critical edge and cave entrance protective device comprise a steel pipe body. A protective steel pipe penetrates through the steel pipe body. A locking mechanism used for fixing the protective steel pipe is placed on one side of the middle of the steel pipe body, and comprises a fixing nut welded on the steel pipe body. A threaded hole of the fixing nut is communicated with a pipe hole of the steel pipe body. A locking bolt with a nut is placed in the threaded hole of the fixing nut. A screw is welded, relative to the other end of the locking mechanism, on the steel pipe body. The screw is placed perpendicular to the steel pipe body. A locking nut is placed at the end, away from the steel pipe body, of the screw. When in construction, the screw is inserted in a screw hole of a shear wall, and is locked by the locking nut. The critical edge and cave entrance protective device is simple in structure, convenient to fix, capable of being repeatedly used and low in cost.

Description

Technical field [0001] The invention relates to auxiliary safety facilities for building construction, in particular to a protective device for a side opening and a fixing method thereof. Background technique [0002] According to the "National Construction Safety Inspection Standard" JGJ59-2011, steel pipes or bamboos should be used to build two protective railings around the floors without protective walls. The existing projects under construction basically use steel pipes for protection, but how about steel pipe protective railings? Fixing, how to make it beautiful has always been the subject of everyone’s research. At this stage, it is often done to fix the root of the protective railing to the concrete floor with expansion screws. Because of expansion, it needs to drill first, and drilling requires machinery and electricity, which is costly. , The construction is more troublesome and time-consuming, leading to many units cutting corners and posing safety risks. Summary of t...
