Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of prefabricated building construction, and in particular to a connection structure of a prefabricated floor slab and a beam. Background Art

[0002] In existing traditional reinforced concrete buildings, beams and floor slabs are cast on site. The on-site casting construction is cumbersome, resulting in a large number of traditional construction workers, and a large amount of supporting accessories and consumables are required during construction. In recent years, prefabricated buildings have developed rapidly, allowing house construction to be manufactured in batches and sets like machine production. Prefabricated buildings are divided into block buildings, plate buildings, and box buildings according to the form of prefabricated parts and construction methods, and are widely used in residential and other fields.

[0003] For example, the dry connection structure of an assembled prefabricated beam and a prefabricated floor slab disclosed in Chinese patent application number CN201720057392.4 is as follows: the first embedded steel plate is spliced ​​with the second embedded steel plate, that is, the steel plug plate on the first embedded steel plate is aligned and inserted into the second reserved channel, and the upper end surface and the lower end surface of the first embedded steel plate and the second embedded steel plate are welded respectively. There are the following technical problems:

[0004] When splicing the first embedded steel plate and the second embedded steel plate, it is necessary to weld the upper end surface and the lower end surface of the first embedded steel plate and the second embedded steel plate respectively one by one. The common welding process is relatively slow, which makes the splicing operation of the first embedded steel plate and the second embedded steel plate relatively cumbersome. Utility Model Content

[0005] To this end, an embodiment of the utility model provides a connection structure between an assembled floor slab and a beam to solve the problem in the prior art that the splicing operation of the first embedded steel plate and the second embedded steel plate is relatively complicated.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0007] A connection structure of assembled floor slabs and beams comprises a connection beam and a prefabricated floor slab.

[0008] A connection assembly for limiting the position of the connection beam and the prefabricated floor slab is installed between the connection beam and the prefabricated floor slab.

[0009] The connection beam is provided with a first limiting hole and a second limiting hole on both sides, and threaded steel bars for limiting the connection assembly are inserted into the cavities of the first limiting hole and the second limiting hole.

[0010] The connection assembly comprises an I-beam, and connection plates for supporting the prefabricated floor slabs are installed in the middle of both ends of the I-beam.

[0011] The two ends of the I-beam are provided with limiting holes five for inserting the threaded steel bars, and the middle part of the connecting plate is provided with limiting holes six and seven for inserting the threaded steel bars.

[0012] Furthermore, concrete is poured into the cavities of the limiting hole one, the limiting hole two, the limiting hole five, the limiting hole six and the limiting hole seven.

[0013] Furthermore, beam-column fixing seats are installed at the upper and lower ends of the connecting beam, and the beam-column fixing seats are installed at the middle part of the beam-column fixing seats.

[0014] Furthermore, a limiting groove 1 and a limiting groove 2 for limiting the I-beam are provided at the left and right ends of the connecting beam, and a slot 1 for inserting the connecting plate is provided at both sides of the connecting beam.

[0015] Furthermore, two sides of the prefabricated floor slab are provided with limiting grooves three for cooperating with a pair of limiting grooves to limit the I-beams, and the side edge of the prefabricated floor slab is provided with slots two for inserting the connecting plates.

[0016] Furthermore, the side of the prefabricated floor slab is provided with a limiting hole three and a limiting hole four for placing threaded steel bars.

[0017] The utility model embodiment has the following advantages:

[0018] 1. Splice the connecting beam and the prefabricated floor slab through the connecting assembly, insert the threaded steel bar into the cavities of the limiting holes 5 and 6 through the cavity of the limiting hole 1, and insert the threaded steel bar into the cavity of the limiting hole 7 through the cavity of the limiting hole 2, so that the I-beam and the connecting plate are firmly fixed on one side of the connecting beam, and then concrete is injected into the cavities of the limiting holes 1 and 2 to increase the stability of the connection between the connecting beam and the connecting assembly.

[0019] 2. After the connection beam and prefabricated floor slab are installed, the connection assembly and the prefabricated floor slab are spliced. After the connection plate is inserted into the hole of slot two, the upper horizontal plate of the I-beam is in the slot of limit slot three, the lower horizontal plate of the I-beam is at the bottom of the prefabricated floor slab, and the vertical plate of the I-beam is close to the side wall of the prefabricated floor slab. Limit holes four, five and six are aligned to facilitate the insertion of threaded steel bars. Limit hole three is aligned with the connection plate to facilitate the insertion of threaded steel bars. Finally, concrete is filled into the holes of limit holes three and four to increase the stability of the connection between the prefabricated floor slab and the connection assembly.

[0032] See also Figure 1-Figure 4 The utility model provides a connection structure of an assembled floor slab and a beam, including a connection beam 100, a prefabricated floor slab 200 and a connection assembly 300. The connection beam 100 and the prefabricated floor slab 200 are spliced ​​by the connection assembly 300, and the connection plate 320 is used to increase stability. The arrangement of the threaded steel bar 10 and the concrete 20 further stabilizes the connection assembly 300.

[0033] The upper and lower ends of the connecting beam 100 are fixedly installed with beam-column fixing seats 110 , and the middle part of the beam-column fixing seats 110 is installed with beam-column 111 .

[0038] The two sides of the prefabricated floor 200 are provided with limiting grooves 3 210 for cooperating with limiting grooves 1 120 to limit the I-beam 310, the upper transverse plate of the I-beam 310 is placed in the groove cavity of the limiting grooves 3 210, and the lower transverse plate of the I-beam 310 is at the bottom of the prefabricated floor 200.
