Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a fixed nut system for steel structures which does not require on-site installation. Background Art

[0002] With the continuous development of the domestic construction industry, prefabricated steel structure building systems have become increasingly important in the industry. The construction process of steel structure building systems is mainly divided into two parts: one is the factory integrated processing of steel structures; the other is the on-site assembly and installation of steel structures. Bolting is a type of steel structure installation process. During the on-site installation of steel structures, workers usually work at high altitudes where there is a lack of fulcrums. Therefore, the workers insert the bolts into the reserved holes on one side of the steel structure, and then go to the other side of the steel structure to screw the nuts into the bolts for connection and installation. The traditional installation process is very difficult and risky in high-altitude construction where there is a lack of fulcrums. Utility Model Content

[0003] The purpose of the utility model is to address the deficiencies of the existing technology and provide a fixed nut system for steel structures that does not require on-site installation. The system comprises a nut and a fixed steel plate, wherein the nut is fixed to the fixed steel plate, wherein a circular hole is opened in the middle of the fixed steel plate, the diameter of the circular hole is larger than the outer diameter of the nut, the nut is installed on one side of the fixed steel plate with the end portion located in the circular hole, and the nut and the fixed steel plate are fixed by welding.

[0004] Preferably, the fixing steel plate has a specification of 50*80*5mm.

[0005] Preferably, the circular hole is formed by cutting, and the diameter of the circular hole is 5 mm larger than the outer diameter of the nut.

[0006] Preferably, the nut on the fixed steel plate is fixed to the steel structure through a fixed round steel provided at the other end of the fixed steel plate, and the fixed round steel allows the center of the steel plate and nut formed as a whole to be aligned and fixed on one side of the reserved bolt hole in the steel structure.

[0007] Preferably, the fixed round steel and the steel structure are fixed by welding.

[0008] Compared with the existing technology, the beneficial effects of the present invention are: the present invention fixes the nut in advance on one side of the reserved hole of the steel structure bolt during the integrated processing process of the steel structure factory through an innovative nut form. When the steel structure is transported to the construction site for installation, the high-altitude workers only need to turn the bolt on one side of the steel structure to firmly install the bolt. While meeting the steel structure installation requirements, it effectively reduces the safety risks of high-altitude workers, simplifies the installation and disassembly process of the steel structure, and shortens the installation and disassembly cycle of the steel structure.

[0013] The technical solution of the present invention is described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0014] Reference Figure 1 and Figure 2 The utility model provides a fixed nut system for steel structure that does not require on-site installation, including a nut 1 and a fixing steel plate 2, wherein the nut 1 is fixed on the fixing steel plate 2, wherein a circular hole is opened in the middle of the fixing steel plate 2, the diameter of the circular hole is larger than the outer diameter of the nut 1, the nut 1 is installed on one side of the fixing steel plate 2 and the end is located in the circular hole, and the nut 1 and the fixing steel plate 2 are fixed by welding. The utility model fixes the nut 1 in advance on one side of the bolt reserved hole of the steel structure 4 during the integrated processing of the steel structure 4 factory through an innovative nut 1 form. When the steel structure 4 is transported to the construction site for installation, the high-altitude workers only need to rotate the bolt on one side of the steel structure 4 to firmly install the bolt, which meets the installation requirements of the steel structure 4 while effectively reducing the safety risks of high-altitude workers.

[0015] In the present invention, firstly, the number of bolts is counted in advance according to the drawings, and 5mm thick steel plates are selected to cut out 2 equal numbers of 50*80mm fixed steel plates, and then a circular hole 5mm larger than the diameter of the nut 1 is cut out at the center position of each fixed steel plate 2, and the nut 1 and its matching gasket are spot welded along the circular hole of the fixed steel plate 2 to form a whole; two φ6 fixed round steels 3 are used to align the center of the steel plate nut 1 that forms the whole and fix it on one side of the reserved bolt hole of the steel structure 4, and welding is adopted between the φ6 fixed round steel 3 and the steel structure 4; the steel structure 4 is transported to the construction site, and the operating personnel insert the bolts into the reserved holes of the steel structure 4 and screw them into the fixed construction nuts 1, and tighten them in place as required; if the steel structure 4 needs to be dismantled after the construction is completed, the operating personnel only need to unscrew the bolts on one side to complete the dismantling operation.

[0016] During the high-altitude installation and disassembly process of the steel structure 4, the utility model adopts a fixed nut 1 system to effectively simplify the installation and disassembly process of the steel structure 4 by prefabricating the nut 1, shortens the installation and disassembly cycle of the steel structure 4, greatly reduces the safety risk of the operators, and has obvious economic, technical and safety benefits.
