Description
Technical Field
[0001] The utility model belongs to the technical field of hollow wall panels, and particularly relates to a precast hollow wall panel convenient for butt joint. Background Art
[0002] Precast hollow wall panels are lightweight, high-strength, heat-insulating, sound-insulating, and fireproof building components produced in factories using special equipment and processes. Precast hollow wall panels generally consist of two layers of steel mesh and one layer of heat-insulating material, with a hollow in the middle. This hollow structure makes the wall panels lightweight and also provides good heat-insulating and sound-insulating properties. Precast hollow wall panels are widely used in residential buildings, public buildings, factories and other buildings, and are suitable for interior and exterior walls and partition walls.
[0003] After retrieval, the "hollow precast wall panel with sound insulation effect" disclosed in the application number "CN202321633848.9" belongs to the same technical field as the present technical solution. In this utility model, first, the wall panel main body is cast in a mold, then the heat-insulating layer is installed on one side of the wall panel main body, and then concrete is used to fixedly connect the heat-insulating layer to the wall panel main body. After that, the middle layer is cast on the heat-insulating layer, and a waterproof layer is installed on the middle layer. The waterproof layer selected is a geomembrane, which needs to be manually hot-melt welded to the middle layer. After welding is completed, the outer shell is cast with concrete. After the concrete solidifies, a damping sheet is installed on the other side of the wall panel main body, and then a sound-absorbing board is installed on the damping sheet. Glue can be used to first install the damping sheet and the sound-absorbing board in place, and then concrete is used for casting. Finally, the outer shell is cast with concrete, and after waiting for the concrete to solidify, it can be transported to the installation site for installation. During installation, the side with the sound-insulating layer faces the interior of the room. When installing two wall panels, they can be connected through a connecting block and a connecting groove, and then the positioning rod is inserted into the positioning groove, and at the same time, the connecting block is also correspondingly installed into the connecting groove; a waterproof layer is installed in the wall panel to prevent rainwater from penetrating into the room when it rains, resulting in the wall panel becoming moldy or damaged after a period of time. At the same time, in summer or winter, the room is prone to overheating or overcooling, or the temperature loss is too fast when the air conditioner is turned on in summer or winter. Therefore, a heat-insulating layer is installed in the wall panel to prevent overheating in summer and overcooling in winter. Due to neighbors upstairs and downstairs or on the left and right, or other events such as road construction around, the surrounding sound is too loud, resulting in some slight vibrations of the wall panel. Installing a damping sheet can absorb some vibrations, and at the same time, a sound-absorbing sponge is installed to absorb the sound that the remaining damping sheet cannot absorb.
[0004] When installing existing precast hollow wall panels, they are usually only positioned between the top and the bottom, and only connected by simple card slots between two horizontally adjacent precast hollow wall panels. This leads to an unstable connection between horizontally adjacent precast hollow wall panels, resulting in cracks in the precast hollow wall panels easily occurring after a period of time. Summary of the Utility Model
[0005] The purpose of the present utility model is to provide a precast hollow wall panel that is convenient for docking, aiming to solve the problem in the prior art that the existing precast hollow wall panels are usually positioned only between the top and the bottom during installation, and the connection between two laterally adjacent precast hollow wall panels is only through a simple card slot, resulting in an unstable connection between the laterally adjacent precast hollow wall panels, and thus the precast hollow wall panels are prone to cracks after a period of time.
[0006] To achieve the above purpose, the present utility model provides the following technical solution: a precast hollow wall panel that is convenient for docking, including a wall panel main body and a hollow groove. A hollow groove is provided inside the wall panel main body. A docking convex block is connected to the end of the wall panel main body. A first threaded tube is connected through the inside of the docking convex block. A second threaded tube is connected through the other end of the wall panel main body. A fixing threaded rod is penetrated through the inside of the second threaded tube.
[0007] To facilitate the mutual clamping of two laterally adjacent wall panel main bodies, preferably, as a precast hollow wall panel that is convenient for docking in the present utility model, a groove matching the docking convex block is provided at the end of the wall panel main body close to the second threaded tube.
[0008] To facilitate the fixed connection of two laterally adjacent wall panel main bodies, preferably, as a precast hollow wall panel that is convenient for docking in the present utility model, the first threaded tube and the second threaded tube have the same size, and the second threaded tube and the fixing threaded rod are in threaded connection.
[0009] To facilitate the connection of the installation shell to the surface of the wall panel main body, preferably, as a precast hollow wall panel that is convenient for docking in the present utility model, an installation shell is fitted and connected to the side surface of the wall panel main body, and a limiting card strip is connected to the inner wall of the installation shell.
[0010] Preferably, as a precast hollow wall panel that is convenient for docking in the present utility model, a metal panel is provided at the opening of the installation shell. A limiting card slot is connected to the inner side of the metal panel. A threaded sleeve is connected through the surface of the metal panel.
[0011] Preferably, as a precast hollow wall panel that is convenient for docking in the present utility model, the metal panel forms a sliding connection with the limiting card strip through the limiting card slot.
[0012] Compared with the prior art, the beneficial effects of the present utility model are:
[0013] In this utility model, after the first wall panel main body is fixed, the docking convex block of the other wall panel main body is inserted into the groove of the first wall panel main body, and the first threaded pipe is aligned with the second threaded pipe. Then, the fixing threaded rod is inserted into the end of the second threaded pipe from the middle and rotated. While the fixing threaded rod rotates inside the second threaded pipe, it can move longitudinally. When the fixing threaded rod moves upward, it can be inserted into the first threaded pipe. When the fixing threaded rod is completely inserted into the first threaded pipe and the second threaded pipe, the two horizontally adjacent wall panel main bodies can be fixedly connected at this time. This makes the docking of two horizontally adjacent wall panel main bodies fast and convenient, and the docked wall panel main bodies are very stable.
[0014] Before installing the wall panel main body, the metal panel drives the limit card slot to slide on the surface of the limit card strip first, so that the metal panel can be installed on the surface of the wall panel main body. After the wall panel main body is installed, the connecting piece required for the installation of the decorative wall panel can be connected through the threaded sleeve inside the metal panel, avoiding directly drilling holes on the surface of the wall panel main body, which may affect the fire prevention and moisture-proof effects of the wall panel main body.
