Problems solved by technology

[0004] The present invention designs a splicing and installation method between laminated slabs at local lowering slabs. By improving the splicing relationship between laminated slabs with height differences, it can effectively solve the problems of easy cracking of dense joints and difficulty in construction of pouring belts after setting height differences. While satisfying the assembly rate, ensuring modular production of laminated slabs, and high-efficiency installation, the structural stress mode at the slab surface with height difference is optimized to effectively solve the problem of cracking and water seepage of the slab surface with height difference under long-term load; at the same time, avoid New laminated slab formwork is added, which reduces the formwork cost of the prefabricated component factory

Embodiment 1

[0033] Such as figure 1 As shown, a prefabricated kitchen and bathroom laminated board splicing structure is divided into a normal area and a lowered board area by the lowered board boundary line 6 under the four-sided support conditions of the wall support 4 and the beam support 5, wherein the height of the lowered board is not greater than 50mm , set the receiving body 3 between the normal area and the lower plate area to strengthen the connection.

[0034] Such as image 3 As shown: the receiving body 3 includes the receiving body longitudinal reinforcement 31, the Z-shaped plate gluten 32 and the receiving body stirrup 33, the receiving body stirrup 33 is located in the middle of the receiving body 3, and the two ends of the Z-shaped plate gluten 32 extend to the bottom of the receiving body 3 outside. Among them, the diameter of the reinforcement bar 32 of the Z-shaped plate and the stirrup bar of the receiving body 33 shall not be less than 8 mm, and the horizontal arr...

Embodiment 2

[0040] Such as figure 1 As shown, a prefabricated kitchen and bathroom laminated board splicing structure is divided into a normal area and a lowered board area by the lowered board boundary line 6 under the four-sided support conditions of the wall support 4 and the beam support 5, wherein the height of the lowered board is not less than 100mm , not more than 300mm, set the receiving body 3 between the normal area and the lower plate area to strengthen the connection.

[0041] Such as Figure 6 and Figure 7 As shown, the structure of this embodiment is roughly the same as that of Embodiment 1, the difference is that the positions of the reserved holes 34 for bottom ribs on the receiving body 3 are different. The reserved hole for the bottom reinforcement of the middle laminated slab is located in the middle of the Z-shaped receiving body 3 (that is, the section where the stirrup of the receiving body is located), below the overlapping section of the receiving body 3 and th...

Abstract

The invention relates to a prefabricated kitchen and toilet composite slab splicing structure and a splicing method, and belongs to the field of prefabricated building components. The structure and the method are characterized in that a post-cast strip between two composite slabs is replaced by a bearing body, a Z-shaped slab reinforcing bar, a bearing body longitudinal bar and a bearing body stirrup in the bearing body are combined into an invisible support similar to a hidden beam, a special structure model is designed so that a reinforcing bar in a bottom slab body of the composite slab can penetrate through the bearing body and is anchored on the bearing body by prestress tensioning, and meanwhile, an elastic anti-cracking material is embedded at a splicing slab seam between the bearing body and the composite slab. According to the structure and the method, the assembling rate is guaranteed, and meanwhile the problems that after the composite slab is disassembled, a slab joint is reinforced, and the slab is prone to cracking and being leaked due to local slab descending are solved.

Description

technical field [0001] The invention belongs to the field of prefabricated building components, and in particular relates to a splicing structure and splicing method of laminated boards of a prefabricated kitchen and bathroom. Background technique [0002] In the design of traditional residential or public toilets, the general scheme is the local lowering slab mode, and it is difficult to meet the prefabrication rate of horizontal components in civil residential buildings without laminated slabs in the bathroom, especially in the bathroom. In the case of many unit-type bathrooms, it is necessary to split the lower panel area of ​​the bathroom to meet the calculation requirements of the assembly rate, and to ensure the functional requirements of crack resistance and waterproof of the bathroom. Therefore, an effective splicing method of laminated panels is urgently needed to ensure the assembly of the bathroom. Reliability in laminated panel applications. [0003] Application...
