Abstract
Description
Technical Field
[0001] This invention specifically relates to the field of prefabricated component technology for building engineering, and more specifically to a prefabricated component production mold assembly mold and its construction method. Background Technology
[0002] In prefabricated buildings, composite floor slabs are increasingly widely used. With the development of prefabricated buildings, the close splicing of precast components in composite slabs has gradually replaced the post-cast strips. The treatment of the joints between the closely spliced precast components has always been a problem. Often, a permanent joint is left between the slabs. Since precast components are generally thick, the permanent joint is not easy to handle. The current treatment method is mostly the downward V-shaped joint. The precast components with this joint are easier to demold, and the demolding of the components does not require demolding, resulting in higher production efficiency. However, this joint is more likely to leave a permanent joint on the bottom of the structural slab, affecting the practicality and aesthetics of the building. X-joints or inverted V-shaped flat joints are also used. This joint can better solve the problem of cracks between the joints. However, since the traditional side formwork design is an integral side formwork, the side formwork obstructs the demolding of the precast components. Each demolding requires the removal of the side formwork, and the side formwork needs to be reassembled for the next production. This seriously affects the production efficiency and increases the amount of repetitive work. Summary of the Invention
[0003] Therefore, the present invention proposes a mold assembly for precast component production and its construction method to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a mold assembly mold for prefabricated component production mold platform, comprising:
[0005] mold table;
[0006] Fixed side mold, two fixed side molds are provided, the two fixed side molds are symmetrical and fixedly set on the platform of the mold table, and a movable side mold is tightly set on one side wall of each fixed side mold facing each other. The bottom end of a connector is fixedly welded to the top surface of each movable side mold, and the top end of the connector is fixedly connected to the fixed side mold by bolts.
[0007] And a fixed middle side mold, which is fixedly set on the table surface of the mold table and located between the two fixed side molds. One or more fixed middle side molds are set according to production needs. The fixed middle side mold is matched with a movable side mold with a pressure cap. The two sides of the middle side mold can be used as side molds respectively, increasing the efficiency of the mold table.
[0008] Furthermore, as a preferred embodiment, the bottom of the side wall of the fixed side mold near the fixed middle side mold is fixedly welded with a chamfered top, and the chamfer is inclined. The bottom of the chamfer is fixedly welded to the table surface of the mold table to form a lower chamfer of the fixed side mold.
[0009] Furthermore, as a preferred embodiment, the angle between the side wall of the fixed side mold close to the fixed middle side mold and the left and right side walls of the middle side mold and the table surface of the mold platform is not less than 90°.
[0010] Furthermore, as a preferred embodiment, the angle between the lower surface of the movable side mold and the left and right side walls of the movable side mold and the table surface of the mold platform is not greater than 90°.
[0011] A construction method for assembling molds for precast component production molds includes the following steps:
[0012] S1: Fix the fixed side mold and the fixed middle side mold on the mold table respectively, wherein the fixed side mold is fixed to the mold table by welding;
[0013] S2: Fix the fixed middle side mold to the mold table with magnets according to the size of the pre-produced component;
[0014] S3: Fix the movable side mold and the movable middle side mold onto the fixed side mold and the fixed middle side mold, respectively;
[0015] S4: Apply release agent, tie steel bars and embedded parts, and pour concrete;
[0016] S5: After the concrete has completely solidified, remove the movable side formwork and the movable middle formwork;
[0017] S6: After the concrete reaches the demolding strength, lift the component off the formwork.
[0018] S7: Clean the mold table, and repeat S3 to S6 to construct the next component.
[0019] The present invention employs the above technology and has the following beneficial effects compared with the existing technology: The device of the present invention divides the side mold into two parts: a fixed side mold and a movable side mold. The fixed side mold refers to the side mold that is kept effectively fixed on the same mold platform when producing a batch of identical components. The outer surface of the fixed side mold is perpendicular to the mold platform or inclined upward. After the precast component is formed, the fixed mold platform does not need to be removed, and the precast component can be easily lifted. Moreover, the fixed side mold effectively maintains the position of the side mold, ensuring that the precast components produced are formed in a consistent manner, reducing the assembly work of the side mold, and improving production efficiency. The movable side mold refers to the side mold that is tightly attached to the fixed side mold before the concrete is poured. After each concrete pour is completed and the concrete has solidified, the movable side mold is removed. The outer surface of the movable side mold is inclined downward, and it is easy to assemble and disassemble the same side mold. Attached Figure Description
