Description

Technical Field

[0001] The utility model relates to the technical field of protection, in particular to a building protection device. Background Art

[0002] Building protection refers to a technical means of protecting and enclosing construction workers and construction sites during the construction of houses and structures. There are protective nets and anti-fall nets outside the building, and inside the building, such as patios, tunnels, through-layers and other locations, due to the large drop, protection is also required. However, since these locations are located indoors and the layout of the surrounding buildings is not easy, the use of traditional scaffolding steel pipes may not necessarily provide stable support points. For example, when the top floor of the through-layer is a wall, the steel pipe cannot be fixed like around the column to obtain a force support point. It can usually only be placed or leaned against the area that needs protection, and cannot provide reliable protection. Utility Model Content

When the sleeve is accidentally rotated, the connecting pipe is more likely to rotate with the sleeve instead of being affected by the friction resistance and moving into the sleeve, thereby reducing the impact of accidental rotation of the sleeve on the fixing stability.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-4 A building protection device comprises a horizontal bar 1, wherein the horizontal bar 1 is provided with two parallel bars at upper and lower positions, a plurality of vertical bars 2 are provided between the upper and lower horizontal bars 1, the vertical bars 2 are fixed to the horizontal bar 1 by scaffolding fasteners 3, the horizontal bar 1 and the vertical bars 2 are both scaffolding steel pipes, and are hollow structures, and both ends of the horizontal bar 1 are installed with abutment plates 4;

[0027] A fixing pipe 5 is welded and installed on the side of the abutment plate 4 facing the crossbar 1, a connecting pipe 6 is provided at the end of the crossbar 1, an end plate 10 is welded and installed on the end of the connecting pipe 6 facing the crossbar 1, and a sleeve rod 11 extending into the crossbar 1 is welded and installed on the end plate 10. Sleeves 7 are provided on the outside of the fixing pipe 5 and the connecting pipe 6. The fixing pipe 5 and the connecting pipe 6 are respectively located at two ends of the sleeve 7. The sleeve 7 is threadedly connected to the fixing pipe 5 and the connecting pipe 6. The sleeve 7 is an internal thread, and the fixing pipe 5 and the connecting pipe 6 are external threads.

[0028] When in use, first assemble the horizontal rail 1 and the vertical rail 2, and then erect the guardrail close to the protection position, such as between adjacent building columns 18 in the figure, the two ends of the horizontal rail 1 are close to the building column 18 but not touching, and a gap for installing the fixed pipe 5 and the connecting pipe 6 is reserved. The sleeve rod 11 is inserted into the end of the horizontal rail 1, and then the abutment plate 4 is pressed against the surface of the building column 18, and the sleeve 7 is rotated. The threaded connection relationship between the sleeve 7 and the fixed pipe 5 and the connecting pipe 6 is used to push the connecting pipe 6 away from the fixed pipe 5, and finally the abutment plates 4 at both ends of the horizontal rail 1 are tightly pressed against the surface of the building column 18, thereby forming a fence to provide a protective effect. For the buildings at the position to be protected, whether they are walls or columns, as long as they are concrete buildings, a counter-fixing effect can be provided.

[0029] In this embodiment, the ends of the fixed tube 5 and the connecting tube 6 located inside the sleeve 7 are welded with convex rings 8, the inner diameter of the sleeve 7 is at least 3 mm larger than the outer diameter of the convex ring 8, and limiting rings 9 are welded on both ends of the sleeve 7. The limiting rings 9 are offset and offset from the convex ring 8, and the limiting rings 9 are threadedly connected to the fixed tube 5 and the connecting tube 6.

[0030] The combination of the convex ring 8 and the limiting ring 9 enables the fixing tube 5, the connecting tube 6 and the sleeve 7 to form a limiting connection relationship so that they will not fall off from each other, thereby facilitating carrying and use.

[0031] In this embodiment, a torsion block 12 is integrally formed and installed on the outer peripheral wall of the sleeve 7, and the cross section of the torsion block 12 is pentagonal.

[0032] The twist block 12 is used to facilitate the rotation of the sleeve 7, and can be rotated using a tool such as a wrench for easy operation.

[0033] In this embodiment, a plurality of lugs 14 are welded and installed on the outer peripheral wall of the connecting pipe 6 at the position of the end plate 10 , and a through hole 15 is opened on the lug 14 .

[0034] When the sleeve 7 is rotated, the connecting tube 6 may rotate with it, thereby affecting its pushing of the crossbar 1 to be tightly fixed, so a lug 14 is provided. When the connecting tube 6 is rotated, a slender tool such as a steel bar or a screwdriver is inserted into the through hole 15, and its rotation is limited by hand to ensure that the sleeve 7 drives the connecting tube 6 to move normally. Of course, a rod can also be directly welded at the position of the lug 14 to directly stabilize it by hand.

[0035] In this embodiment, a plurality of ball holes 17 are evenly formed on one side of the end plate 10 close to the end of the horizontal rail 1 , and balls 16 are installed in the ball holes 17 , and the end of the horizontal rail 1 abuts against the surface of the balls 16 .

[0036] The provision of the ball 16 reduces the frictional resistance between the connecting tube 6 and the crossbar 1. When the sleeve 7 is accidentally rotated, the connecting tube 6 is more likely to rotate with the sleeve 7 instead of being affected by the frictional resistance and moving into the sleeve 7, thereby reducing the impact of the accidental rotation of the sleeve 7 on the fixing stability.

[0037] In this embodiment, a plurality of convex cones 13 are evenly welded and installed on the front surface of the abutment plate 4 away from the fixing pipe 5 .

[0038] The convex cone 13 increases the friction resistance when the butt plate 4 hits the surface of the building column 18, reduces the displacement of the butt plate 4 on the building column 18 when colliding with the horizontal rail 1 or the vertical rail 2, ensures its position stability, and further ensures stability and reliability after fixation.
