Description

Technical Field

[0001] This application relates to the field of building structure engineering technology, and in particular to a prefabricated teaching building corridor structure. Background Technology

[0002] Prefabricated building technology is now widely used in various public buildings such as schools, hospitals, and commercial complexes. Among them, the standardization of connecting corridors, as transitional spaces connecting different functional areas, directly affects construction efficiency. Traditional cast-in-place concrete connecting corridors have problems such as long curing cycles and large consumption of formwork. Existing prefabricated connecting corridors mostly adopt steel frame or precast concrete slab combination structures, which greatly shortens on-site operation time.

[0003] The existing precast concrete box-type corridors are constructed by casting ribbed box-type components as a whole, which are then transported to the site and spliced ​​using post-tensioned prestressing. However, due to the large weight of each component, large hoisting equipment is required, which leads to a surge in transportation and hoisting costs.

[0004] Therefore, this application provides a prefabricated teaching building corridor structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a prefabricated teaching building corridor structure that overcomes the deficiencies of existing technologies. It aims to solve the problem that existing precast concrete box-type corridors, which are integrally cast into ribbed box-type components and then transported to the site for post-tensioning and splicing, suffer from the problem of soaring transportation and hoisting costs due to the large weight of each component and the need for large hoisting equipment.

[0006] To achieve the above objectives, this application provides the following technical solution: a prefabricated teaching building corridor structure, comprising two sets of beams, with two sets of far-away positioning mechanisms at the bottom of the beams, and a limiting groove at the top of the beams. Several sets of prefabricated slab mechanisms are arranged above the two sets of beams, with two sets of limiting blocks fixedly installed at the bottom of each prefabricated slab mechanism. The two sets of limiting blocks are respectively inserted into the corresponding limiting grooves. Two sets of through holes are provided inside each prefabricated slab mechanism, and the two sets of through holes in adjacent sets of prefabricated slab mechanisms are connected. Prestressed steel strands are threaded through several sets of connected through holes in the same row. End sealing plates are provided at both ends of each set of prefabricated slab mechanisms, and several sets of high-strength bolts are installed at the bottom of the end sealing plates. Steel sleeves are fixedly installed at both ends of the prestressed steel strands through the two sets of end sealing plates.

[0007] By adopting the above technical solution, both sets of beams are connected to the teaching building structure through two sets of positioning mechanisms at the bottom. Then, several sets of precast slab structures are hoisted in sequence, and the corresponding limiting slots of the two sets of limiting blocks at the bottom of the precast slab structures are aligned and inserted to form a mechanical engagement. Then, two sets of prestressed steel strands are passed through the perforations in the precast slab structures to connect the precast slab structures, forming a continuous force-bearing system. Two sets of end sealing plates are used to seal both ends of the precast slab structures. The end sealing plates are connected to the teaching building structure through several sets of high-strength bolts. Then, the two ends of the prestressed steel strands are fixed by steel sleeves. This application greatly reduces the single-piece transportation weight of the large-span corridor components, thereby reducing the component transportation cost.

[0008] As a preferred technical solution of this application, the top of the beam is provided with two sets of channels, and two sets of steel beams are welded to the channels, with a curtain wall inserted between the two sets of steel beams.

[0009] By adopting the above technical solution, rapid assembly can be achieved by installing two sets of steel beams in the channel and then installing the curtain wall between the two sets of symmetrically arranged steel beams.

[0010] As a preferred technical solution of this application, the positioning mechanism includes a bracket, which is fixedly installed at the bottom end of the beam. A fixing plate is fixedly installed at the bottom of the bracket, and a number of sets of high-strength bolts are threadedly connected to the outer circumference of the fixing plate.

[0011] By adopting the above technical solution, both ends of the beam extend into the interior of the teaching building, and the beam is supported by two sets of corbels. It is directly connected to the main building structure by high-strength bolts, which improves the support strength.

[0012] As a preferred technical solution of this application, the precast panel mechanism includes a panel, which is fixedly installed on the top of two sets of limiting blocks. A lower side protrusion is provided on one side of the panel, and an upper side protrusion is provided on the side of the panel away from the lower side protrusion. Two adjacent sets of panels are connected by the lower side protrusion and the upper side protrusion, and an anti-slip layer is fixedly connected to the top of the lower side protrusion.

[0013] By adopting the above technical solution, the two adjacent sets of plates are connected by the side lower convex plate and the side upper convex plate, which increases the contact area when the two sets of plates are connected. With the anti-slip layer, the stability of the two sets of plates when connected is improved.

[0014] As a preferred technical solution of this application, a sealing strip is fixedly installed at the installation end of the channel, and the sealing strip covers the bottom of the steel beam and the curtain wall.

[0015] By adopting the above technical solution, using EPDM rubber for the sealing strip, and using a hot-melt welding process to cover the joint between the steel beam and the bottom of the curtain wall, the tightness of the steel beam and curtain wall installed in the channel is improved.

[0016] As a preferred technical solution of this application, a shock-absorbing pad is fixedly installed at the bottom end of the fixing plate, and the shock-absorbing pad has a rubber layer.

[0017] By adopting the above technical solution, the shock-absorbing pads buffer the shear force, thereby enhancing the seismic resistance of the positioning mechanism.

[0018] As a preferred technical solution of this application, the curtain wall adopts lightweight ALC wall panels.

[0019] By adopting the above technical solutions, ALC wall panels have a better ability to bear structural loads, and the structural self-weight is reduced, further reducing transportation and hoisting costs.

[0020] The beneficial effects of this application are: 1. Both sets of beams are connected to the teaching building structure through two sets of positioning mechanisms at the bottom. Then, several sets of precast slab structures are hoisted in sequence. The corresponding limiting slots of the two sets of limiting blocks at the bottom of the precast slab structures are aligned and inserted to form a mechanical engagement. Then, two sets of prestressed steel strands are passed through the perforations in the precast slab structures to connect the precast slab structures and form a continuous force-bearing system. Two sets of end sealing plates are used to close the two ends of the precast slab structures. The end sealing plates are connected to the teaching building structure through several sets of high-strength bolts. Then, the two ends of the prestressed steel strands are fixed by steel sleeves. This application greatly reduces the single-piece transportation weight of the large-span corridor components, thereby reducing the component transportation cost.

[0021] 2. Rapid assembly is achieved by installing two sets of steel beams in the channel and then installing the curtain wall between the two symmetrically arranged steel beams. Attached Figure Description
