Description
Technical Field
The present invention relates to building prefabricated components, and in particular to a prefabricated wall panel.
Background
The precast concrete member is a concrete member that has been processed in a factory in a standardized and mechanized manner before being installed at a construction site. Common concrete prefabricated parts include a concrete prefabricated floor slab, a concrete prefabricated box girder for a bridge, a concrete prefabricated roof truss girder for an industrial factory building, a concrete prefabricated pile for foundation treatment and the like.
Compared with cast-in-place concrete, the use of concrete prefabricated parts has more advantages. First, a relatively stable work environment in a factory has a higher safety factor for construction workers than a complex worksite work environment. Secondly, the quality of the concrete prefabricated parts can be more effectively controlled in a factory through mechanized production. Moreover, the standardization of the size and characteristics of the precast concrete members can significantly accelerate the installation speed and the progress of construction works.
However, when a user wants to finish a room and change the original house type of the room, the user first needs to break the corresponding wall plate with a tool such as a hammer, and then rebuild the wall at a predetermined position to partition the room. However, in the process of dismantling the original wallboard and washing the brickwork, more building materials are consumed.
Disclosure of Invention
In view of the above, the present invention provides a prefabricated wall panel, which has the advantages of complete dismantling of the prefabricated wall panel and reduced building material consumption.
In order to solve the technical problems, the technical scheme of the invention is as follows: a prefabricated wall panel comprises a wall panel body and a wall panel connecting piece; wallboard connecting piece includes connecting reinforcement and spacing post, connecting reinforcement has a plurality ofly and establishes separately the left and right sides of wallboard body, and sets up left connecting reinforcement of wallboard body is in with the setting dislocation from top to bottom the connecting reinforcement on wallboard body right side, and the both ends of connecting reinforcement are all fixed in the wallboard body, just connecting reinforcement with wallboard body cooperation forms spacing cavity, spacing post is used for passing adjacent two wallboard body is a plurality of spacing cavity.
Through above-mentioned technical scheme, when needs splice two prefabricated wallboards, order about two prefabricated wallboards and be close to each other for a plurality of connecting reinforcement on the left of wallboard body enter into between a plurality of connecting reinforcement on another wallboard body right side, and the spacing cavity on two prefabricated wallboards communicates each other. And then the control limit column penetrates through a limit cavity between the two prefabricated wallboards to limit the two prefabricated wallboards, so that the two prefabricated wallboards can not be separated. And finally, pouring concrete at the joint of the two prefabricated wallboards so as to fixedly connect the two prefabricated wallboards.
When an owner wants to finish a room and change the original house type of the room, a hammer is used for knocking the joint of the two prefabricated wall boards. Because the junction of two prefabricated wallboards is provided with connecting reinforcement and spacing post, so the concrete of two prefabricated wallboard junctions is thinner, can comparatively conveniently knock off. After the concrete between two prefabricated wallboards is knocked off basically, can use the instrument to cut off spacing post, so can remove the limiting action of spacing post to two prefabricated wallboards. The wall panel can then be removed from the floor and moved to a designated location for changing the room configuration.
