Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a prefabricated wall and its connection structure for low-rise residential self-built houses. Background Technology

[0002] With the development of the construction industry, precast walls have been widely used in self-built houses to improve construction efficiency. Currently, when splicing existing precast wall panels, it is necessary to tie stirrups and longitudinal steel bars on site to connect adjacent precast wall panels, which is not only inefficient but also has high material costs.

[0003] Therefore, it is necessary to design a prefabricated wall system and its connection structure for low-rise residential self-built houses to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a prefabricated wall structure and its connection structure for low-rise residential self-built houses.

[0005] The technical solution of this utility model is: a precast wall for low-rise residential self-built houses, including a precast wall body; both ends of the precast wall body are provided with a first connection notch; and a number of transverse steel bars extending from the connection notches at both ends of the precast wall body are evenly distributed from top to bottom in the precast wall body.

[0006] The top of the precast wall body is provided with several upper connecting sleeves evenly distributed along its length; the bottom of the precast wall body is provided with lower connecting sleeves that correspond one-to-one with the upper connecting sleeves.

[0007] The precast wall body has several main reinforcement bars evenly distributed along its length; the top of the main reinforcement bars is fixed to the upper connecting sleeve, and the bottom extends into the lower connecting sleeve corresponding to the upper connecting sleeve.

[0008] The top of the precast wall body is provided with a second connection notch for connection with the floor slab; a number of structural reinforcement bars are evenly distributed along the length direction inside the precast wall body; the top of the structural reinforcement bars is bent laterally at the second connection notch.

[0009] The bottom inner side of the precast wall body is provided with a positioning step for positioning with the floor slab.

[0010] The precast wall is an integrated precast wall with reverse-laid stone.

[0011] A connection structure for prefabricated walls used in low-rise self-built residential houses, as described above, includes a transverse connection structure; the transverse connection structure includes transverse connecting steel bars; a cast-in-place groove is formed between the first connection notches at the transverse ends of two adjacent prefabricated wall bodies, and the transverse steel bars between the two adjacent prefabricated wall bodies are welded together by the transverse connecting steel bars; concrete is poured into the cast-in-place groove.

[0012] It also includes a vertical connection structure; the vertical connection structure includes vertical connecting steel bars; one end of the vertical connecting steel bar extends into the lower connecting sleeve at the bottom of the upper precast wall body, and the other end extends into the upper connecting sleeve at the top of the lower precast wall body; the connecting sleeve is filled with concrete.

[0013] The joints at the horizontal ends of two adjacent precast wall panels are filled with building sealant.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects: First connecting notches are provided at both ends of the transverse ends of the precast wall body. Several transverse reinforcing bars extending from the connecting notches at both ends of the precast wall body are evenly distributed from top to bottom within the precast wall body. When two precast wall bodies are joined at their transverse ends, the two first notches form a pouring groove. After connecting the corresponding two transverse reinforcing bars with transverse connecting reinforcing bars, concrete is poured into the pouring groove on-site to complete the transverse connection of the precast wall body. This not only reduces the amount of on-site formwork and reinforcing bars, but also eliminates the need for on-site tying of stirrups and longitudinal reinforcing bars, greatly reducing the amount of reinforcing bars and labor costs, thereby reducing material and labor costs, while improving construction efficiency and shortening the construction cycle.

[0025] Furthermore, in order to facilitate the vertical connection of two adjacent precast wall bodies 1, a number of upper connecting sleeves 4 are evenly distributed along the length direction on the top of the precast wall body 1; and a lower connecting sleeve 5 corresponding to the upper connecting sleeves 4 is provided at the bottom of the precast wall body 1.

[0026] Furthermore, in order to improve the overall structural stability of the precast wall body 1, a number of main reinforcing bars 6 are evenly distributed along the length direction inside the precast wall body 1; the top of the main reinforcing bars 6 is fixed to the upper connecting sleeve 4, and the bottom extends into the lower connecting sleeve 5 corresponding to the upper connecting sleeve 4.

[0027] Furthermore, in order to facilitate the connection between the precast wall body 1 and the floor slab, the top of the precast wall body 1 is provided with a second connection notch 7 for connection with the floor slab; a number of structural reinforcement bars are evenly distributed along the length direction inside the precast wall body 1; the top of the structural reinforcement bars is bent laterally at the second connection notch 7 so as to anchor the structural reinforcement bars into the floor slab and ensure the integrity.

[0028] Furthermore, in order to facilitate the positioning between the precast wall body 1 and the floor slab, the bottom inner side of the precast wall body 1 is provided with a positioning step 8 for positioning with the floor slab.

[0029] Furthermore, in order to further improve construction efficiency, the precast wall is an integrated precast wall with reverse-engineered stone.

[0030] A connection structure for prefabricated walls used in low-rise self-built residential houses, as described above, includes a transverse connection structure; the transverse connection structure includes transverse connecting steel bars 9; a cast-in-place groove is formed between the first connection notches 2 at the transverse ends of two adjacent prefabricated wall bodies 1, and the transverse steel bars 3 between the two adjacent prefabricated wall bodies 1 are welded together by the transverse connecting steel bars 9; concrete is poured into the cast-in-place groove.

[0031] The connection structure of the precast wall for low-rise self-built residential buildings in this embodiment also includes a vertical connection structure; the vertical connection structure includes vertical connecting steel bars 10; one end of the vertical connecting steel bar 10 extends into the lower connecting sleeve 5 at the bottom of the upper precast wall body 1, and the other end extends into the upper connecting sleeve 4 at the top of the lower precast wall body 1; the connecting sleeve is filled with concrete. In this embodiment, the precast wall body 1 is connected vertically to the upper connecting sleeve 4 and the lower connecting sleeve 5 using vertical connecting steel bars 10, which can reduce the amount of steel bars and connecting sleeves used, and can use composite slab components without steel bars, thereby saving the formwork cost of precast slab components produced by the precast factory and reducing production costs.

[0032] Furthermore, the joints at the transverse ends of two adjacent precast wall bodies 1 are filled with building sealant to ensure the airtightness between the two adjacent precast wall bodies 1.

[0033] In this embodiment, the horizontal assembly nodes of the prefabricated walls and their connecting structures for low-rise self-built residential buildings are assembled and connected using a beveled keyway method. The connection is achieved by welding the horizontal connecting steel bars on-site, which reduces the amount of on-site formwork and steel bars. This node method eliminates the need for on-site tying of stirrups and longitudinal steel bars, greatly reducing the amount of steel bars and labor, thereby saving costs.

[0034] In this embodiment, the prefabricated wall and its connecting structure for low-rise self-built residential buildings are connected in the vertical direction by connecting the vertical connecting steel bars 10 with the upper connecting sleeve 4 and the lower connecting sleeve 5. The structural steel bars can be anchored into the floor slab to ensure the integrity. This method of node construction reduces the amount of steel bars and connecting sleeves used, and can use composite slab components without steel bars, thereby saving the formwork cost of prefabrication plants for producing composite slab components and reducing production costs.
