Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a prefabricated prestressed double-T slab frame structure. Background Technology

[0002] In the field of building construction, prefabricated buildings are increasingly widely used due to their advantages such as high construction efficiency and stable quality. Double-T slabs, as a common prefabricated component, have the characteristics of large span and high load-bearing capacity, and are widely used in the floor and roof structures of multi-story and high-rise buildings.

[0003] However, existing prefabricated double-T slab frame structures have some problems in practical applications. Due to the large volume and weight of the double-T slabs, the positioning of the double-T slabs is not accurate enough when using equipment to hoist them onto the precast beams, which can easily lead to large gaps at the joints of the double-T slabs. This not only affects the integrity and stability of the structure, but may also cause problems such as leakage. Therefore, this application proposes a prefabricated prestressed double-T slab frame structure. Utility Model Content

The bottom ends of the two ribs in the double T plate are respectively fitted into the positioning grooves on the corresponding support bases. Triangular plate-shaped reinforcing plates are installed between the two sides of the vertical part of the support base and the top of the horizontal part, and the bottom end of the inclined surface of the reinforcing plate extends to the positioning groove.

[0007] Optionally, the distance between the two sides of the inner wall of the first connecting groove gradually decreases from top to bottom. The top of the support plate is provided with a second connecting groove, and the two ends of the second connecting groove are respectively connected to the first connecting groove on the corresponding support seat. The cross-sectional shape of the second connecting groove is the same as that of the first connecting groove. The connecting plates at the bottom of the two panel docking ends are fitted into the first connecting groove at the top of the two support seats and the second connecting groove at the top of the support plate. The side wall of the connecting plate is in contact with the inner wall of the first connecting groove and the second connecting groove.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1-6 This utility model provides a technical solution: a prefabricated prestressed double-T slab frame structure, including a precast beam 1 and double-T slabs. Multiple stud assemblies are equidistantly installed on the top of the precast beam 1, and each stud assembly is fitted with a support seat 4 that fits against the top of the precast beam 1. The support seat 4 is an inverted T-shaped structure, and a first connecting groove 8 is provided at the top of the vertical part of the support seat 4. Multiple double-T slabs are arranged in a parallel configuration, and each double-T slab includes a horizontal panel 21 and two vertical ribs 22 at its bottom ends. Each panel... Both sides of the bottom of panel 21 are provided with downward protruding connecting plates 23, and the connecting plates 23 at the joint of each pair of adjacent panels 21 are fitted into the first connecting grooves 8 at the top of the corresponding two support seats 4. A support plate 10 is installed between the two support seats 4 at the corresponding positions. The support plate 10 is located at the bottom of the joint of the two panels 21. The fitting design of the support seat 4 and the connecting plate 23 realizes the positioning and support of the double T plate, improves the assembly accuracy, and the support plate 10 enhances the support rigidity at the joint of the panels 21, reduces the splicing gap, and improves the overall structure.

[0027] like Figure 1 and Figure 2 As shown, positioning grooves 7 are provided at the top of both ends of the horizontal part of the support base 4, and the shape and size of the positioning grooves 7 are adapted to the bottom end of the rib plate 22. The bottom ends of the two rib plates 22 in the double T plate are respectively fitted into the positioning grooves 7 on the corresponding support base 4. Triangular plate-shaped reinforcing plates 41 are installed between the two sides of the vertical part of the support base 4 and the top of the horizontal part. The bottom end of the inclined surface of the reinforcing plate 41 extends to the positioning groove 7. The fitting of the positioning groove 7 and the rib plate 22 can assist in the accurate positioning of the double T plate installation and avoid installation offset. The triangular reinforcing plate 41 can enhance the structural strength of the support base 4, improve the shear resistance, and ensure the stability of load transfer. At the same time, the reinforcing plate 41 can also guide the docking of the rib plate 22 and the positioning groove 7. Under the guidance of the inclined surface of the reinforcing plate 41, it is easy for the two rib plates 22 at the bottom of the double T plate to be accurately embedded into the corresponding positioning grooves 7.

[0028] like Figure 3 and Figure 4As shown, the distance between the two sides of the inner wall of the first connecting groove 8 gradually decreases from top to bottom. The top of the support plate 10 is provided with a second connecting groove 11, and the two ends of the second connecting groove 11 are respectively connected to the first connecting groove 8 on the corresponding support base 4.

The connecting plate 23 at the bottom of the two panel 21 is fitted into the first connecting groove 8 at the top of the two support bases 4 and the second connecting groove 11 at the top of the support plate 10. The side wall of the connecting plate 23 is in close contact with the inner wall of the first connecting groove 8 and the second connecting groove 11. The trapezoidal cross-section of the first connecting groove 8 and the second connecting groove 11 forms a "wedge" effect, which enhances the reliability of the connection between the connecting plate 23 and the support base 4 and the support plate 10, thereby improving the tightness of the panel 21 joint.

[0029] like Figure 3 and Figure 4 As shown, the top of the support base 4 and both sides of the first connecting groove 8 are provided with first sealing grooves 9 at equal intervals. The top of the support plate 10 and both sides of the second connecting groove 11 are provided with second sealing grooves 12 at equal intervals. The bottom of both sides of the panel 21 and the sides of the connecting plate 23 are provided with sealing strips 24. The shape of the sealing strips 24 is adapted to the shape of the first sealing grooves 9 and the second sealing grooves 12, and the sealing strips 24 can be tightly connected with the first sealing grooves 9 and the second sealing grooves 12. The cooperation of the sealing strips 24 with the first sealing grooves 9 and the second sealing grooves 12 forms a waterproof sealing system, which can increase the sealing effect at the joint between the panel 21 and the support plate 10 and the support base 4, thereby preventing rainwater leakage.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown, connecting components 13 are provided between the bottom of both ends of the support plate 10 and the corresponding support base 4. The connecting component 13 includes a support block 131, a connecting post 134, a screw 135, and a second nut 136. The support block 131 is fixedly installed on the side wall of the vertical part of the support base 4 and located directly below the end of the support plate 10. A square groove 132 is opened on the top of the support block 131, and a through hole 133 communicating with the square groove 132 is opened on the bottom of the support block 131. The connecting post 134 is fixedly installed on the bottom of both ends of the support plate 10, and the connecting post 134... The screw 135 is fixedly installed at the bottom of the connecting post 134 and inserted into the square groove 132 at the top of the support block 131. The screw 135 is also inserted through the through hole 133. The second nut 136 is threaded onto the screw 135 and abuts against the bottom of the support block 131. The support plate 10 can be installed between the two support seats 4 through the connecting assembly 13, so that the second connecting groove 11 on the support plate 10 is precisely connected with the first connecting groove 8 at the top of the vertical part of the support seat 4, thereby allowing the support plate 10 to provide support and sealing at the joint of the panel 21.

[0031] like Figure 1 and Figure 2 As shown, each stud group consists of four studs 3. Each of the four corners of the horizontal part of the support base 4 has a through-hole 5, and the four through-holes 5 on the horizontal part of the support base 4 are respectively fitted onto the four studs 3. A first nut 6 is threaded onto the top of each stud 3 and abuts against the top of the horizontal part of the support base 4. The studs 3 can realize the installation and positioning of the support base 4, enhance the connection reliability between the support base 4 and the precast beam 1, and prevent loosening.

[0032] like Figure 1 As shown, four rectangular lifting rings 211 are installed at both ends of the top of the panel 21, and the lifting rings 211 are set as inverted U-shapes. The double T-plates can be easily lifted by the lifting rings 211 at both ends of the panel 21.
