Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a floor edge protection device for a facade without an external frame for protection. Background Art

[0002] In the field of construction technology, edge protection is a commonly used facility in housing construction, especially in high-rise buildings that currently use attached lifting external scaffolding. The quality of edge protection is particularly important for safety. Traditional floor edge protection methods include using steel pipes to directly install and fix with expansion bolts and ferrules, using expansion hooks and steel ropes for protection, and using fixed protective nets and expansion bolts for fixation. However, the above protection methods all have great limitations. In addition, using expansion bolts to fix on the wall will damage the structural wall and affect plastering and subsequent decoration. The bolts need to be ground and removed, which is very labor-intensive. The method of using expansion bolts to fix the fixed protective net requires drilling holes in the structural plate surface to implant bolts, which also affects the structural plate and increases the risk of leakage. The protection method using expansion hooks and steel ropes has insufficient rigidity of the steel rope, which affects the protection effect. In addition, since the tools such as expansion bolts are disposable intervention devices, they cannot be reused, and the material cost is increased. Summary of the Invention

[0003] In response to the deficiencies of the prior art, the present invention provides an edge protection clamp, which improves the edge clamp in the prior art and avoids the damage to the building wall and the high labor cost caused by the expansion bolt fixing method in the prior art.

[0008] Furthermore, the telescopic threaded rod has telescopic adjustment knobs at both ends, and the telescopic range of the telescopic threaded rod can be adjusted by rotating the adjustment knobs;

[0009] Furthermore, the retractable threaded rod is a tension screw rod with a diameter of 14 mm;

[0010] Furthermore, the fixing plate is made of equilateral angle iron, and the area size of the fixing plate is 50mm×50mm;

[0011] Furthermore, the fixing plate is made of equilateral angle iron, and the thickness of the fixing plate is 3 mm;

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the drawings in the embodiments of the present invention, different types of section lines are not marked according to national standards, nor are there any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the figures.

[0026] Figure 1 This is a front view of the installation and use of the device of the present invention. A temporary protective fixture is installed on the wall 1a. The temporary protective fixture has a retractable threaded rod 1b, and fixed plates 1c are provided at both ends of the retractable threaded rod 1b. The retractable threaded rod 1b has one or more steel pipe connecting members 1e, which can fix one end of the horizontal steel pipe 1d. When the temporary protective fixture needs to be installed, it is adjusted through the retractable threaded rod 1b. Since the fixed plates 1c are welded to both ends of the retractable threaded rod 1b, when the retractable threaded rod 1b is extended or retracted, the fixed plates 1c are clamped to the wall 1a, thereby fixing the retractable threaded rod 1b and the wall 1a. In addition, the retractable threaded rod is a 14mm diameter tension screw, and the fixed plates are made of equilateral angle iron with an area size of 50mm×50mm. The fixed plates are also made of equilateral angle iron with a thickness of 3mm.

[0027] Figure 2 This is a schematic diagram of an embodiment of the present invention. A temporary protective fixture is installed on the side wall 2a, which has a retractable threaded rod 2b and fixed plates 2c at both ends near the retractable threaded rod 2b. The retractable threaded rod 2b has one or more steel pipe connecting members 2e. The steel pipe connecting member 2e can fix one end of the horizontal steel pipe 2d. When the temporary protective fixture needs to be installed, it is adjusted through the retractable threaded rod 2b. Since the fixed plates 2c are welded to both ends of the retractable threaded rod 2b, when the retractable threaded rod 2b is extended or retracted, the fixed plates 2c are clamped to the wall 2a, thereby fixing the retractable threaded rod 2b and the wall 2a. The steel pipe connecting member 2e is fixed to the sliding member 2f. When the horizontal steel pipe 2d needs to be moved horizontally, this can be achieved by moving the sliding member 2f. When the position is determined, the position is fixed using the locking device on the sliding member 2f. In addition, the retractable threaded rod is a tension screw rod with a diameter of 14 mm, the fixing plate is made of equilateral angle iron, the area size of the fixing plate is 50 mm × 50 mm, and the fixing plate is made of equilateral angle iron, and the thickness of the fixing plate is 3 mm.

[0028] Figure 3This is a schematic diagram of an embodiment of the present invention. A temporary protective fixture is installed on the side wall 3a. It has a retractable threaded rod 3b and fixed plates 3c at both ends near the retractable threaded rod 3b. The retractable threaded rod 3b has one or more steel pipe connecting members 3e, which can fix one end of the horizontal steel pipe 3d. When the temporary protective fixture needs to be installed, it is adjusted through the retractable threaded rod 3b. Because the fixed plates 3c are welded to both ends of the retractable threaded rod 3b, when the retractable threaded rod 2b is extended or retracted, the fixed plates 3c clamp against the wall 3a, thereby fixing the retractable threaded rod 3b and the wall 3a. The steel pipe connecting member 3e is directly attached to one or more fixed plates 2c and is directly used to fix the horizontal steel pipe 3d. In addition, the retractable threaded rod is a 14mm diameter tension screw, and the fixed plates are made of equilateral angle iron. The fixed plates have an area size of 50mm×50mm and a thickness of 3mm. In addition, the fixed plates are made of equilateral angle iron.

[0029] Figure 4 This is a schematic diagram of the retractable threaded rod of the present invention. By adjusting the adjusting knob 4c, the external sleeve 4b and the external internal threaded rod 4d move in parallel to achieve movement toward or away from each other, and drive the fixed plate 4a to clamp the wall. The sliding member 4e is fixed in position by its accompanying locking device, and the external sleeve 4b and the internal threaded rod 4d are coupled by threaded nesting.
