Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and more specifically, it relates to a prefabricated double-T slab. Background Technology

[0002] Precast concrete double-T slabs that meet national standards typically have a limited number of embedded steel reinforcement meshes. While ensuring the double-T slab meets strength and other performance requirements, the number of steel reinforcement meshes is minimized. Traditionally, a single horizontal steel reinforcement mesh is often placed within a double-T slab. To ensure it is embedded in the middle of the vertical direction, a support assembly is needed to elevate the mesh; otherwise, the finished double-T slab will be unusable due to exposed reinforcement mesh. Therefore, this invention proposes a precast double-T slab. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a precast double-T slab with high structural strength and convenient casting construction.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to a prefabricated double-T slab, comprising a double-T slab body, with integrally formed wing plates on the left and right sides of the double-T slab body. A support plate extending downwards and symmetrically arranged on the left and right sides is provided at the bottom of the double-T slab body, also integrally formed with the double-T slab body. A first and second rib mesh arranged horizontally are embedded within the double-T slab body, with the second rib mesh located below the first rib mesh. Both the left and right sides of the first and second rib mesh extend into the wing plates. A third rib mesh arranged vertically is embedded within the support plate, with its upper end extending into the interior of the double-T slab body.

[0005] The present invention is further configured such that: the first reinforcing mesh, the second reinforcing mesh and the third reinforcing mesh are each composed of several transverse reinforcing bars arranged in parallel with each other and several longitudinal reinforcing bars arranged in parallel with each other;

[0006] Any transverse steel bar on the first reinforcing mesh is tied to all longitudinal steel bars with steel wire; any longitudinal steel bar on the first reinforcing mesh is tied to all transverse steel bars with steel wire.

[0007] Any transverse reinforcement bar on the second reinforcement mesh is tied to all longitudinal reinforcement bars with steel wire; any longitudinal reinforcement bar on the second reinforcement mesh is tied to all transverse reinforcement bars with steel wire.

[0008] Any transverse reinforcing bar on the third reinforcing mesh is tied to all longitudinal reinforcing bars with steel wire, and any longitudinal reinforcing bar on the third reinforcing mesh is tied to all transverse reinforcing bars with steel wire.

[0009] The present invention is further configured such that: a first bundle block is provided between the first reinforcing mesh and the second reinforcing mesh to control the distance between them; the top of the first bundle block has a first positioning groove for embedding a transverse or longitudinal reinforcing bar on the first reinforcing mesh; and the bottom of the first bundle block has a second positioning groove for embedding a transverse or longitudinal reinforcing bar on the second reinforcing mesh.

[0010] The present invention is further configured such that: a second bundle block is provided between the first reinforcing mesh and the second reinforcing mesh to control the distance between them, and a binding opening is opened on the side of the second bundle block for a transverse or longitudinal reinforcing bar on the first reinforcing mesh and a transverse or longitudinal reinforcing bar on the second reinforcing mesh to be laterally embedded.

[0011] The present invention is further configured such that: the first bundle block is provided with a positioning groove, and the second bundle block is provided with a positioning protrusion, the positioning protrusion being fitted into the positioning groove.

[0012] The present invention is further configured such that both the first bundle block and the second bundle block are made of concrete.

[0013] The present invention is further configured such that the third reinforcing mesh is connected to the first reinforcing mesh and the second reinforcing mesh.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. Arrange a double-layer steel reinforcement mesh within the double-T slab body to improve the strength and other performance indicators of the precast double-T slab.

[0016] 2.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0022] Example 1

[0023] See Figure 1 As shown, this embodiment involves a prefabricated double-T slab, including a double-T slab body 100. Wing plates 101 are integrally formed on the left and right sides of the double-T slab body 100. A support plate 102 extends downwards and is symmetrically arranged at the bottom of the double-T slab body 100, also integrally formed with the double-T slab body 100. A first rib mesh 1 and a second rib mesh 2 are horizontally arranged within the double-T slab body 100, with the second rib mesh 2 located below the first rib mesh 1. Both the left and right sides of the first rib mesh 1 and the second rib mesh 2 extend into the interior of the wing plates 101. A third rib mesh 3 is vertically arranged within the support plate 102, with its upper end extending into the interior of the double-T slab body 100.

[0024] Furthermore, the first reinforcing mesh 1, the second reinforcing mesh 2, and the third reinforcing mesh 3 are all composed of several parallel transverse reinforcing bars (not shown) and several parallel longitudinal reinforcing bars (not shown).

[0025] Any transverse steel bar on the first reinforcing mesh 1 is tied to all longitudinal steel bars with steel wire, and any longitudinal steel bar on the first reinforcing mesh 1 is tied to all transverse steel bars with steel wire.

[0026] Any transverse reinforcing bar on the second reinforcing mesh 2 is tied to all longitudinal reinforcing bars with steel wire, and any longitudinal reinforcing bar on the second reinforcing mesh 2 is tied to all transverse reinforcing bars with steel wire.

[0027] Any transverse reinforcing bar on the third reinforcing mesh 3 is tied to all longitudinal reinforcing bars with steel wire, and any longitudinal reinforcing bar on the third reinforcing mesh 3 is tied to all transverse reinforcing bars with steel wire.

[0028] Example 2

[0029] See Figures 1 to 3As shown, the precast double-T slab involved in this embodiment is further configured based on embodiment 1, wherein a first bundle block 4 is provided between the first reinforcing mesh 1 and the second reinforcing mesh 2 to control the distance between them. The top of the first bundle block 4 has a first positioning groove 401 for embedding a transverse or longitudinal reinforcing bar on the first reinforcing mesh, and the bottom of the first bundle block 4 has a second positioning groove 402 for embedding a transverse or longitudinal reinforcing bar on the second reinforcing mesh.

[0030] Furthermore, a second bundle block 5 is provided between the first reinforcing mesh 1 and the second reinforcing mesh 2 to control the distance between them. A binding opening 501 is opened on the side of the second bundle block 5, and the binding opening 501 allows a transverse or longitudinal reinforcing bar on the first reinforcing mesh 1 and a transverse or longitudinal reinforcing bar on the second reinforcing mesh 2 to be laterally embedded.

[0031] Furthermore, the first bundle 4 is provided with a positioning groove 403, and the second bundle 5 is provided with a positioning protrusion 502, which is matched and embedded in the positioning groove 403.

[0032] Furthermore, both the first bundle 4 and the second bundle 5 are made of concrete.

[0033] In this embodiment, the first bundle block 4 restricts the downward movement of the reinforcing bar inserted into the first positioning groove 401 and restricts the upward movement of the reinforcing bar inserted into the second positioning groove 402. The second bundle block 5 restricts the upward movement of the reinforcing bar inserted into the first positioning groove 401 and restricts the downward movement of the reinforcing bar inserted into the second positioning groove 402.

[0034] The positioning groove 403, in conjunction with the positioning protrusion 502, serves to position the first bundle 4 and the second bundle 5 during assembly.

[0035] Example 3

[0036] See Figures 1 to 3 As shown, the prefabricated double-T slab involved in this embodiment is further configured, based on embodiments 1 and 2, such that the third rib mesh 3 is connected to the first rib mesh 1 and the second rib mesh 2.

[0037] In this implementation scheme, by setting the third reinforcing mesh 3 to be connected to the first reinforcing mesh 1 and the second reinforcing mesh 2, the third reinforcing mesh 3 will not shift within the formwork during the pouring construction, thus achieving a mutual limiting effect.

[0038] The precast double-T slab involved in this utility model improves the strength and other performance indicators of the precast double-T slab by arranging a double-layer steel reinforcement mesh within the slab body. Furthermore, by using a first bundle block and a second bundle block that are combined with each other, the two horizontally arranged steel reinforcement meshes can be separated vertically, thereby controlling the spacing between the two steel reinforcement meshes, ensuring smooth casting of the precast double-T slab, making the casting construction more convenient, and providing complete overall functionality and strong practicality.
