Description

Technical Field

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. In the process of prefabrication of wall modules of buildings, formwork casting is mostly used. Existing formworks are mostly made of wooden formworks, but they are not convenient for recycling and reuse, and wooden structures are prone to damage. Some formworks are made of steel structure materials. Since the steel structure formworks are heavy, the hoisting and assembly and disassembly processes are relatively inconvenient.

The invention provides a mold for a wall panel body assembled from multiple mold plates. When in use, bases of different lengths are used in conjunction with columns of appropriate lengths, and an appropriate number of mold plates are used to form a wall casting mold. Then, a steel skeleton is placed, and the steel bars used for assembly and connection are limited in position using a steel bar guide device. After casting, the module plate and other plates are pulled out and disassembled after the casting is completed and finalized, and a qualified prefabricated building wall component is obtained, which effectively solves the problem that the existing aluminum alloy mold plate structure is troublesome in the assembly process and the bottom of the mold plate is prone to bulging and causing deformation of the plate.

When walls of different lengths need to be cast, a plugging plate 901 of appropriate thickness is installed on the outer wall of the fixed side plate 904 according to the actual required wall length, so that the length of the casting space enclosed by the fixed side plate 904, the movable side baffle 8, the overlapping side plate 1 and the mobile frame 2 can be adjusted.

[0044] Example 4

[0045] See also Figure 1 and Figure 2 A removal mechanism 7 is provided on the upper side of the base 6 for unloading the cast formwork from the base 6 .

[0046] Specifically, the removal mechanism 7 includes a screw rod 705 rotatably connected to the inside of the pull-out groove 602 , the screw rod 705 extends out of the side wall of the base 6 and is fixedly connected to the shaft rod 703 , and an insertion rod 704 for rotating the shaft rod 703 is inserted inside the shaft rod 703 .

[0047] Furthermore, the removal mechanism 7 also includes a movable base plate 701 slidably mounted on the inner side of the pull-out groove 602, a screw rod 705 extends into the interior of the movable base plate 701 and is threadedly connected thereto, and a movable wheel 702 is provided at the bottom end of the movable base plate 701 away from the base 6, and the movable wheel 702 is flush with the bottom end of the base 6.

[0048] Working principle of this embodiment: after demoulding is completed, the shaft 703 is rotated by the insertion rod 704, and the shaft 703 drives the screw 705 to rotate, so that the movable bottom plate 701 slides out of the pull-out groove 602, so that the wall is separated from the plugging plate 901 and the material is removed from the upper side of the base 6. It should be noted that the contact area between the movable bottom plate 701 and the bottom end of the wall is larger than the contact area between the plugging plate 901 and the side end of the wall. Therefore, the plugging plate 901 is easier to separate from the side end of the wall. If necessary, a gap can be reserved between the overlapping side plate 1 and the wall, and the wall can be slightly shaken to separate it from the plugging plate 901. As for the separation of the movable bottom plate 701 from the bottom end of the wall, the separation can be carried out during the transportation process after the wall is moved out from the upper side of the base 6, or when the wall is on the upper side of the base 6, the wall is clamped by the overlapping side plates 1 on both sides, and then the movable bottom plate 701 is pulled out, so that the movable bottom plate 701 is separated from the bottom end of the wall.

[0049] Working principle and use process of this application: When pouring the wall, first, according to the size of the building wall to be poured, the opening and closing template structure of this device is adjusted accordingly. Specifically, according to the height of the wall to be poured, an appropriate number of overlapping side panels 1 are set up in the plug-in cavity 202 opened on the inner side of each mobile frame 2, so that it can meet the height of the wall to be poured. The spacing between two adjacent mobile frames 2 is adjusted by the opening and closing mechanism 5, and the two-way screw rod 503 is rotated by the turntable 502. Under the guidance limit of the two guide rods 501, the two mobile frames 2 can approach or move away from each other, so as to meet the needs of pouring walls of different thicknesses (widths). Under the action of the movable side baffle 8 and the fixed side panel 904, the two sides of the pouring space are blocked, so that a complete pouring space can be enclosed between the fixed side panel 904, the movable side baffle 8, the overlapping side panel 1 and the mobile frame 2.

[0050] Afterwards, the U-shaped frame 402 is installed between the two mobile frames 2 by tightening the bolts 401, and the movable side baffle 8 is squeezed and limited by the abutment block 403 on the outer wall of the U-shaped frame 402. When it is necessary to cast walls of different lengths, a plugging plate 901 of appropriate thickness is installed on the outer wall of the fixed side plate 904 according to the actual required wall length, so that the length of the casting space surrounded by the fixed side plate 904, the movable side baffle 8, the overlapping side plate 1 and the mobile frame 2 can be adjusted. In addition, before casting, the disc 302 is rotated to adjust the position of the connecting plate 304, and then the screw 305 is rotated so that the extrusion block 303 at the bottom of the screw 305 can squeeze the top of the overlapping side plate 1 at the top, so that the multiple overlapping side plates 1 vertically overlapped together can have good stability during casting.

[0051] After pouring is completed and the wall is formed, the screw 305 is rotated upward to remove the extrusion of the extrusion block 303 on the top of the overlapping side plate 1. After that, the bidirectional screw 503 is rotated by the turntable 502, and the two movable frames 2 can be moved away from each other under the guide limit of the two guide rods 501, so that the overlapping side plates 1 on the two movable frames 2 can automatically move away from each other, and the simultaneous demoulding of the two sides of the wall is completed. After that, the fastening bolts 401 are screwed out, the U-shaped frame 402 is disassembled, and the movable side baffle 8 is separated from the poured wall. Next, the shaft rod 703 is rotated by the insertion rod 704, and the shaft rod 703 drives the screw rod 705 to rotate, so that the movable bottom plate 701 slides out of the pull-out groove 602, so that the wall is separated from the plugging plate 901 and the material is removed from the upper side of the base 6.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
