Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an installation structure for a prefabricated steel arched roof for building construction. Background Technology

[0002] Arched roofs are a type of architectural roof with unique structural and aesthetic value. Their basic principle is to use the arch structure to transfer the load borne by the roof to the supporting structure on both sides through the curve of the arch. They have the characteristics of strong load-bearing capacity and beautiful appearance, and are widely used in various types of building construction.

[0003] The current installation structure for precast steel arched roofs involves fabricating steel into arched precast beams in a factory, welding arch feet to both ends of the beams, and then using expansion bolts to fix the beams to the building's roof slab. However, this fixing method is cumbersome, labor-intensive, and significantly reduces the installation efficiency of arched roofs. Furthermore, the expansion bolts driven into the building's roof slab can easily cause secondary damage, thus affecting the construction quality of the roof slab. To address these issues, this improved solution has been developed. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure for prefabricated steel arched roofs in building construction. This installation structure enables convenient installation of prefabricated steel arch beams without causing secondary damage to the roof slab of the building, thereby improving installation efficiency and ensuring construction quality.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a prefabricated steel arch roof installation structure for a building, comprising a building body, a building roof slab formed on the building body, a plurality of prefabricated steel arch beams, and arch feet set at both ends of each prefabricated steel arch beam. The plurality of prefabricated steel arch beams are arranged in a straight-line interval along the horizontal direction. The building roof slab has two pre-embedded connecting beams. The two connecting beams correspond to the two arch feet of the prefabricated steel arch beams and extend along the arrangement direction of the prefabricated steel arch beams. An assembly structure is provided between the arch feet and the connecting beams. A fastening component is provided between the arch feet and the connecting beams to fix the arch feet and the connecting beams in the assembled state.

[0006] By adopting the above technical solution, the connecting beams are pre-embedded in the building's roof slab during the pouring process. Then, an assembly structure is used to quickly assemble the precast steel arch beams and the connecting beams. Finally, fastening components are used to secure the precast steel arch beams to the connecting beams. This achieves convenient installation of the precast steel arch beams without causing secondary damage to the building's roof slab, thereby improving installation efficiency and ensuring construction quality.

[0007] The assembly structure is further configured such that: the assembly structure includes a docking slot disposed on one side wall of the two docking beams facing each other, and a docking plug fixedly disposed on the two arch feet and used for insertion into the docking slot.

[0008] By adopting the above technical solution, the docking blocks are inserted into the docking slots to form a convenient assembly of the prefabricated steel arch beam and the docking crossbeam. This setting method has a simple structure, is easy to assemble, and has low processing costs.

[0009] The further configuration is as follows: the docking slot extends along the length of the docking beam to form a long strip, and the two docking blocks are located on opposite sides of the two arch feet.

[0010] By adopting the above technical solution, this structural arrangement enables the connecting beam to better bear the downward pressure on the precast steel arch beam, thereby playing a better pressure-bearing role.

[0011] The fastening component is further configured such that: the fastening member includes a plurality of fastening components, each group of fastening components including a fastening bolt that passes sequentially through the connecting beam and the arch foot, and a fastening nut that is threadedly connected to the fastening bolt.

[0012] By adopting the above technical solution, the fastening bolts pass through the connecting beam and the arch foot in sequence and are tightened with the fastening nut thread, thereby achieving the fixation of the precast steel arch beam on the connecting beam.

[0013] A further feature is provided: a reinforcing structure is provided between the connecting beam and the arch foot.

[0014] By adopting the above technical solutions, the structural design is strengthened to further enhance the structural strength at the connection between the arch foot and the connecting beam, thereby improving the structural strength of the fixed precast steel arch beam and enabling it to bear greater loads.

[0015] The reinforcement structure is further configured to include a reinforcement hole fixedly disposed at the bottom of the docking slot and a reinforcement block fixedly disposed on the docking block and inserted into the reinforcement hole.

[0016] By adopting the above technical solution, the docking block drives the reinforcing block to be inserted into the reinforcing hole during the process of inserting into the docking slot. This structure can better bear the force of the precast steel arch beam in the horizontal direction, thereby achieving higher structural strength.

[0017] The precast steel arch beam is further configured such that: the precast steel arch beam includes a left-shaped beam having one of the arch feet and a right-shaped beam having the other arch foot, the left-shaped beam and the right-shaped beam are connected by a main beam through a fixing component, and adjacent main beams are integrally connected to form a whole.

[0018] By adopting the above technical solution, the precast steel arch beams are configured as left-shaped beams and right-shaped beams, thereby reducing the processing difficulty and requirements of the precast steel arch beams, and thus reducing processing costs. Furthermore, the main beams connect adjacent precast steel arch beams, thereby improving the overall structural strength of the precast steel arch beams.

[0019] The fixing assembly is further configured to include fixing bolts that pass sequentially through the left beam, the main beam, and the right beam, as well as fixing nuts that are threadedly connected to the fixing bolts.

[0020] By adopting the above technical solution, the fixing bolts are passed through the left beam, the main beam and the right beam in sequence and then tightened with the fixing bolt threads, thereby realizing the convenient fixing of the left beam and the right beam to the main beam.

[0021] The method is further configured such that: a drainage trough with an upward opening is formed on one side of the precast steel arch beam opposite to the connecting crossbeam, and the drainage trough extends along the length direction of the connecting crossbeam.

[0022] By adopting the above technical solution, the drainage channel is designed to receive rainwater falling from the roof, and the structure can effectively prevent rainwater from seeping into the roof slab, thereby avoiding water seepage.

[0023] In summary, this utility model has the following beneficial effects: it enables convenient installation of precast steel arch beams without causing secondary damage to the roof slab of the building, thereby improving installation efficiency and ensuring construction quality.
