Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of installation and fixation of light steel canopies, in particular to a double-U-shaped simple support for small-span canopies. Background Technique
[0002] In the prior art, generally, light steel canopies are usually fabricated and constructed secondly after the main building construction is completed, and light steel canopies may also be newly added after the building function is transformed. The conventional practice of such canopy structures is to use adhesive chemical anchor bolts to implant into the original main structure. After the structural adhesive hardens, the steel structure canopy beam is installed. This method has relatively high construction requirements. First, the hardening of the structural adhesive requires a process, which prolongs the construction period. Second, drilling is required in the original structure, and the original structural steel bars may be damaged during the drilling process. Third, strict requirements are imposed on the performance of the structural adhesive, and its durability, aging resistance, etc. need to be strictly guaranteed. The structural adhesives on the market are uneven and of mixed quality, and there is an abuse phenomenon, which brings potential safety hazards to the project. In view of this, in-depth research on the above problems has led to the generation of this case. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the utility model provides a double-U-shaped simple support for small-span canopies, which solves the problems raised in the background technique.
[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A double-U-shaped simple support for small-span canopies includes a long-leg U-shaped connecting piece and a short-leg U-shaped connecting piece. The long-leg U-shaped connecting piece and the short-leg U-shaped connecting piece are arranged above the structural beam slab and surround the structural column, and the side wall of the short-leg U-shaped connecting piece is welded and fixed to the canopy beam.
[0005] The above-mentioned long-leg U-shaped connecting piece and the short-leg U-shaped connecting piece are connected and fixed by high-strength bolts, and the connection position of the high-strength bolts is located within the building enclosure wall.
[0006] The above-mentioned long-leg U-shaped connecting piece and the short-leg U-shaped connecting piece are both made of Q235B grade steel.
[0007] The number of the above-mentioned high-strength bolts is not less than four groups.
[0008] The surface of the connection position of the above-mentioned high-strength bolts is poured with a cement mortar surface layer.
[0009] The utility model provides a double-U-shaped simple support for a small-span canopy, which has the following beneficial effects: the double-U-shaped simple support for the small-span canopy adopts two U-shaped connectors with long limbs and short limbs, which are placed on the structural beam slab and surround the structural column, and the support connection can be completed by tightening with high-strength bolts. The construction is simple and the method is reliable; the connector is placed on the structural beam slab, and the structural beam slab can be used as the anti-slip carrier of the support to resist the bending moment of the canopy beam; the U-shaped connector is designed with long and short limbs to make the connection position of the high-strength bolt inside the building enclosure wall without being exposed; the U-shaped connector surrounding the column can effectively prevent the support from slipping down; the high-strength bolt bears the tensile and compressive forces, and the surface is plastered with a cement mortar layer; the construction is simple and fast, only need to prefabricate the U-shaped connector and install it on site, which greatly saves the construction period; in addition, drilling and implanting anchor bolts in the original structure are avoided, the damage to the original structure is avoided, and the bearing capacity of the base concrete does not need to be repeatedly checked.
