Embodiment 1

[0026] Example 1, such as figure 1 , figure 2 , image 3 As shown, this embodiment aims to provide a splicing joint of precast concrete shear walls that is convenient for on-site connection. Therefore, the splicing joints of precast concrete shear walls provided by this embodiment include precast concrete walls and The double-layer reinforced mesh inside the wall, the size of the prefabricated concrete wall is the same as the existing shear wall, generally the height of the first floor. The double-layer steel mesh is the steel mesh set at the front and back, and it is also composed of horizontal steel bars set horizontally and vertical steel bars set vertically to form a grid mesh structure.

[0027] Different from the existing integrated steel plate, the key improvement of this embodiment is that the upper and lower ends of the precast concrete wall are pre-embedded with spliced ​​steel plates for connecting the upper and lower precast concrete shear walls, and the spliced...

Embodiment 2

[0036] Embodiment 2, this embodiment provides the construction method of the splicing joint of the precast concrete shear wall provided by embodiment 1

[0037] Firstly, the splicing steel plate at the lower part of the splicing node of a prefabricated precast concrete shear wall is fixed to the constructed lower wall by welding or bolting (the lower wall can be the foundation wall or the first floor that has been implemented. The splicing node of the prefabricated concrete shear wall, the foundation wall is the foundation poured at the construction site, and the splicing steel plates required for the connection are pre-embedded on the foundation), the welding and bolt fixing methods are mainly splicing the upper and lower pieces Adding a steel plate to one side of the steel plate to connect the upper and lower steel plates is a common method in existing prefabricated buildings, so it will not be described in detail in this embodiment.

[0038] Then start from the splicing nod...

Abstract

The invention belongs to the field of prefabricated building structures, and particularly relates to a spliced joint of prefabricated concrete shear walls and a construction method thereof. The spliced joint comprises a prefabricated concrete wall body and a double-layer reinforcing mesh arranged in the prefabricated concrete wall body; and splicing steel plates used for connecting an upper prefabricated concrete shear wall and a lower prefabricated concrete shear wall are pre-buried in the upper end and the lower end of the prefabricated concrete wall body and extend out of the prefabricatedconcrete shear walls to be arranged. According to the spliced joint and the construction method thereof, the prefabricated concrete shear walls connected by adopting the steel plates are manufacturedin a workshop, the upper shear wall and the lower shear wall can be spliced on site just in a bolted connection mode or a welded mode, the advantage that steel structures are convenient to connect andthe advantage of the strength of concrete are well combined, and therefore the traditional site wet construction amount can be greatly decreased, the defect that site construction is difficult due tothe fact that the prefabricated concrete shear walls are connected by adopting a grouting sleeve can be overcome, the prefabrication rate and the construction speed can be increased, and the splicedjoint and the construction method thereof are particularly suitable for prefabricated buildings.

Description

technical field [0001] The invention belongs to the field of prefabricated building structures, and in particular relates to a splicing node of a prefabricated concrete shear wall and a construction method thereof. Background technique [0002] With the continuous promotion of prefabricated building policies and the improvement of market acceptance, the development of prefabricated buildings is currently in full swing. Enterprises in various regions are scrambling to develop prefabricated buildings. Various prefabricated building structural systems have emerged, showing a hundred schools of thought. trend. [0003] In prefabricated buildings with shear wall structures, prefabricated concrete shear walls and prefabricated concrete-steel plate composite shear walls are mostly used. For precast concrete shear walls, the vertical connection technology of shear walls has always attracted much attention. At present, the main connection method is grouting sleeve connection. As a ...
