Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Fig. 1-4 illustrate an embodiment of the present invention.
1-4, a mounting lifting point device for a steel stair stringer, the mounting lifting point device comprising: a clamp and a lifting lug.
The fixture comprises an L-shaped left fixture 1 and a J-shaped right fixture 2 which are detachably connected and are both made of steel plates, a first mounting plate 3 is welded at the lower end of the L-shaped left fixture 1, a second mounting plate 4 is welded at the lower end of the J-shaped right fixture 2, the first mounting plate 3 and the second mounting plate 4 are detachably connected through four groups of bolt assemblies 5, and the L-shaped left fixture 1 and the J-shaped right fixture 2 can be assembled to form an inverted T-shaped groove; a wedge groove 6 is formed in the J-shaped right clamp 2, a triangular anti-skidding wedge block 7 is arranged in the wedge groove 6, a spring 8 is arranged at the front end of the anti-skidding wedge block 7, a positioning plate 9 is connected to the outer side, located on the wedge groove 6, of the J-shaped right clamp 2, a strip-shaped clamping groove is formed in the positioning plate 9, and the spring 8 is clamped on the strip-shaped clamping groove of the positioning plate 9 to prevent the anti-skidding wedge block 7 from sliding; the upper surface of the anti-skid wedge 7 is distributed with saw teeth.
The lifting lug 10 is arranged at the lower end of the J-shaped right clamp 2, is made of Q355B and is PL20 × 120 × 100 in model, and the lifting lug 10 is provided with a groove and is welded with the J-shaped right clamp 2 to form a whole.
In the implementation of the embodiment, the clamp is arranged below the installed steel stair beam, the lower part of the I-shaped steel beam 11 is arranged in an inverted T-shaped groove formed by the L-shaped left clamp 1 and the J-shaped right clamp 2, the left clamp and the right clamp are fastened by the bolt assembly 5, the anti-skid wedge 7 is arranged in the wedge groove 6, the wedge groove 6 is provided with the spring 8, the clamp can be prevented from sliding downwards along the oblique beam under the stress state, the wedge is tighter when the stress is larger, and the sawtooth on the contact surface of the wedge and the steel beam can increase the friction force between the wedge and the steel beam, so that the clamp and the steel beam 11 are clamped under the stress state; and after the lower part component is installed in place, loosening the bolt assembly 5 on the clamp, and taking down the clamp.
This embodiment is the assembled, can used repeatedly, can reduce field weld and cutting work volume, and convenient and fast practices thrift construction cost, improves the efficiency of construction.
The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, all the same principle is within the patent protection scope of the present invention.
