Detailed Description

The present application is described in further detail below in conjunction with figures 1-4.

The embodiment of the application discloses a face limit guard bar in building outer wall entrance to a cave.

Referring to fig. 1 and 2, a border guard bar for an opening of an outer wall of a building includes an extension steel frame 1 and a guard bar body 2 fixed to the extension steel frame 1. When the scaffold outside the building outer wall is built, the extending steel frames 1 are pre-installed on the scaffold at the position of the building edge hole, the extending steel frames 1 are round tubes, the number of the extending steel frames 1 is multiple, the extending steel frames are horizontally arranged on the scaffold at intervals, and the extending steel frames are arranged on the scaffold in an upper layer and a lower layer. One end of the extension steel frame 1 is fixed on the scaffold, and the other end extends to the position of the building edge opening. The guardrail body 2 is fixed at one end of the extended steel frame 1 far away from the scaffold and is positioned at the position of the building edge opening.

Referring to fig. 2, the guardrail body 2 includes two horizontally disposed cross bars 21 and a plurality of vertically disposed vertical bars 22. Wherein, horizontal pole 21 and montant 22 are hollow metal side's pipe, have the cavity in the inside. The length of the cross bar 21 is slightly less than the width of the building at the edge opening. The vertical bars 22 are used for connecting the two cross bars 21, and the vertical bars 22 are arranged at intervals along the length direction of the cross bars 21. The cross bar 21 and the vertical bar 22 are fixed in a manner of being welded or connected through a hoop, and a welded mode is adopted here, so that the structural strength of the guardrail body 2 is higher. The height of the guardrail body 2 is 500 mm-1000 mm, preferably 800mm here, so that the guardrail body 2 can play a protective role and the guardrail body 2 is light in weight.

Referring to fig. 2 and 3, the fence body 2 is fixed to the extension steel frame 1 by a locking member 3. The locking member 3 includes a mounting plate 31, a locking ring 32, and a pressing block 33. The mounting plate 31 is a square plate, and is arranged between the extension steel frame 1 and the cross bar 21. The locking ring 32 is fitted over the outer side of the extension steel frame 1 and fixed to the bottom surface of the mounting plate 31. The locking ring 32 includes an upper ring portion 321 and a lower ring portion 322. The upper ring portion 321 and the lower ring portion 322 are each semi-circular in cross section. The upper ring portion 321 is fixed on the mounting plate 31 by a screw, one end of the lower ring portion 322 is hinged to one end of the upper ring portion 321, and the other end of the lower ring portion 322 is fixedly connected with the other end of the upper ring portion 321 by a fixing bolt. The locking ring 32 is tightened on the extension steel frame 1 by tightening the fixing bolt. In this embodiment, the number of the locking rings 32 is two, and the locking rings are arranged at intervals along the length direction of the extension steel frame 1, so that the locking rings are more firmly installed on the extension steel frame 1 and are not easy to slide along the extension steel frame 1. The pressing block 33 has a C-shaped cross section and is provided with an arrangement groove 331 for arranging the cross bar 21 and adapting to the cross-sectional shape of the cross bar 21. The length of the press block 33 is equal to the width of the mounting plate 31. The pressing block 33 is fixed to the upper surface of the mounting plate 31 by screws, and the pressing block 33 presses the cross bar 21 against the mounting plate 31 after the cross bar 21 is disposed in the disposition groove 331.

Referring to fig. 2 and 4, in order to further secure the fence body 2 at the building edge opening location, the four corners of the fence body 2 are provided with support assemblies 4. The support assembly 4 comprises a tightening screw 41, a fixed block 42 and a driving member 43. Wherein, the fixed block 42 is a square block which is matched with the inner cavity of the cross rod 21. The fixed block 42 is slidably mounted in the interior cavity of the cross bar 21. The tightening screw 41 is disposed in the inner cavity of the cross bar 21, one end of the tightening screw 41 is in threaded connection with the fixed block 42, and the other end extends out of the inner cavity of the cross bar 21. The driving member 43 is capable of driving the tightening screw 41 to move horizontally in the cavity of the cross bar 21 and enabling the end of the tightening screw 41 away from the cross bar 21 to be tightened against the wall at the position of the building edge opening. The driving member 43 includes a fixing sleeve 431 fixed to an end of the cross bar 21 and a driving nut 432. The fixing sleeve 431 includes a fixing portion 4311 sleeved on the cross bar 21 and adapted to the cross section of the cross bar 21, and a cylindrical rotating portion 4312 welded to the fixing portion 4311. One end of the drive nut 432 is rotatably connected to the rotating portion 4312, and the other end is screwed to the tightening screw 41. The drive nut 432 has a polygonal cross section such that the drive nut 432 can be rotated by a tool such as a wrench. Since the tightening screw 41 is restrained by the fixed block 42 and cannot rotate, the tightening screw 41 can slide horizontally along the longitudinal direction of the cross bar 21 by rotating the drive nut 432.

Referring to fig. 2 and 4, one end of the abutment screw 41, which is far from the cross bar 21, is tapered, and is screwed with an abutment piece 44, and a rubber gasket 45 is glued to the end surface of the abutment piece 44, which is far from the cross bar 21. When the abutting screw 41 abuts against the wall at the position of the building edge opening, the tip of the abutting screw 41 can be inserted into the wall, and the rubber gasket 45 can be tightly attached to the wall, so that the abutting screw 41 is tightly pressed on the wall more firmly.

Referring to fig. 2 and 4, when the support assemblies 4 are mounted at the four corners of the guardrail body 2, and the support assemblies 4 are abutted against the wall of the adjacent side of the building, the guardrail body 2 can be further fixed at the opening of the adjacent side of the building.

Referring to fig. 2, a layer of support plate 5 is further laid on the upper surface of the extension steel frame 1, and the support plate 5 is fixed on the extension steel frame 1 through screws, so that the safety of the guardrail body 2 is improved, and if a constructor falls down to the outer side of a building edge at the guardrail body 2, the support plate 5 can catch the constructor, so that the safety of the constructor is ensured; and the backup pad 5 can supply constructor to stand, and constructor can stand on backup pad 5 and construct the building and face limit entrance to a cave position.

Referring to fig. 1 to 4, the installation steps of the edge protection fence of the building outer wall hole in the embodiment of the application are as follows:

1. pre-installing the extension steel frame 1 on a scaffold;

2. tightening the locking ring 32 of the locking piece 3 on the extension steel frame 1; the cross bar 21 of the guardrail body 2 is pressed on the mounting plate 31 through the pressing block 33;

3. the support assemblies 4 are installed at the four corners of the guardrail body 2, and the tightening screw 41 is pressed on the wall at the position of the building edge opening by rotating the driving nuts 432.
