Problems solved by technology

[0007] The purpose of the present invention is to provide a horizontal connection structure and construction method of double T-plate prefabricated components, to solve the technical problems that the existing horizontal connection structure has holes in the roof to weaken the local bearing capacity, and subsequent sealing construction is likely to cause hidden dangers; And solve the technical problem of poor lateral rigidity of the rib beam and unreliable connection when the connection position is located at the position of the rib beam, which limits the application range of the plate body

Embodiment 1

[0041] Example 1 see figure 1 , 3 As shown in -6, when the required horizontal support force is small:

[0042] The horizontal connection structure of this prefabricated concrete double T-slab comprises a double T-slab and a vertical component located below the double T-slab and fixedly connected to it, the vertical component 1 is a column or a wall, and the double T-slab includes The upper horizontal top plate 2 and the lower two rib beams form a π shape with the top plate and the two rib beams.

[0043] The two rib beams include a proximal rib beam 31 close to the vertical member and a distal rib beam 32 away from the vertical member, and the vertical member 1 is located directly below the proximal rib beam 31 .

[0044]A horizontal beam bottom connecting rod 6 is fixedly connected between the bottoms of the two rib beams. The beam bottom connecting rod 6 is vertical to the vertical member 1 in space. The two ends of the beam bottom connecting rod 6 include vertical The p...

Embodiment 2

[0048] Example 2 see Figure 2-6 As shown, when the required horizontal support force is large:

[0049] The difference from Embodiment 1 is that the partially closed space truss structure also includes a diagonally braced steel rod 7 arranged along the diagonal in the closed space, and the top of the diagonally braced steel rod 7 is fixed to the distal rib beam 32 Connect, the bottom of the diagonally braced steel rod 7 is fixedly connected with the connecting rod 6 at the bottom of the beam.

[0050] The top of the distal rib beam 32 and the side located in the closed space are pre-embedded with a beam side top embedded part 8, the beam side top embedded part 8 is a vertical steel plate, and the diagonally braced steel rod 7 The top of the beam is fixedly connected to the top embedded part 8 on the beam side, and the bottom of the diagonal bracing steel rod 7 is fixedly connected to the upper side of the proximal end of the connecting rod 6 at the bottom of the beam.

Abstract

The invention discloses a horizontal connection structure for prefabricated concrete double-T plates and a construction method of the horizontal connection structure. The horizontal connection structure comprises the double-T plates and a vertical component, a pi shape is formed by top plates of the double-T plates and two ribbed beams, a beam bottom connecting rod is fixedly connected between thebottoms of the two ribbed beams, a sealed space is defined by the middles of the top plates and the two ribbed beams at the position through the beam bottom connecting rod, a locally-closed space truss structure is formed by the double-T plates, a component top pre-buried part is pre-buried at the top of the vertical component, and a horizontal connecting part is connected between the beam bottomconnecting rod and the component top pre-buried part. By arranging the beam bottom connecting rod connected between the bottoms of the two ribbed beams of the double-T plates, the double-T plates aretransformed into the locally-closed space structure with the large lateral-stiffness resisting performance, the ability to resist horizontal force of the local part of the component is improved, thehorizontal force transmitted from a lower structure is transmitted to the plane of a plate surface with large plane stiffness, and thus the purposes of providing an effective lateral supporting pointfor the lower structure and effectively transmitting the horizontal force are achieved.

Description

technical field [0001] The invention relates to the field of structural connection of prefabricated components, in particular to a horizontal connection structure of concrete prefabricated double T-slabs and a construction method thereof. Background technique [0002] Prestressed concrete double T-slab is a prefabricated load-bearing member with beam and slab integrated. It uses high-strength steel wire or steel strand and high-performance concrete to optimize the design of beam height and slab thickness. To the simple and beautiful components. In order to achieve the purpose of cost-effectiveness, the thickness of the double T plate is very thin. At present, the total height of the double T plate commonly used in China is 350mm-900mm, and the width of the rib beam is 80mm-100mm. π-shaped structure, the horizontal stiffness of the bottom of the rib beam is relatively poor. In structural buildings with double T-plate roofs, the tops of vertical components such as gable wind...
