Description

Technical Field

[0001] The utility model relates to the technical field of concrete prefabrication, in particular to a modular mould for concrete prefabricated components. Background Art

[0002] Precast concrete components are building components made in advance in factories using concrete as the basic material, including beams, slabs, columns and building decoration accessories. When prefabricating such precast concrete components, precast formwork is usually used to support the concrete so that it can be formed in the formwork. After forming, it can be demoulded to obtain a complete precast component. With the development of the modern construction industry, the use of precast concrete components has become increasingly widespread, and the types of formwork used for precast components are also increasing.

[0003] In response to this, Chinese patent number CN220864293U proposes a modular mold for concrete prefabricated components that is easy to assemble and disassemble. This utility model has the advantages of simple structure, easy mold disassembly and assembly, and high construction efficiency.

[0004] However, after the prefabricated components in the template are formed, the above technology requires the staff to loosen the bolts and then pry apart the side templates to achieve demoulding, which requires a lot of effort from the staff. In addition, the production batch of prefabricated components is large. Long-term use of such molds requires a lot of time in the demoulding process, which reduces production efficiency and reduces the convenience of using the device. In this regard, this design proposes a modular mold for concrete prefabricated components. Utility Model Content

[0005] In order to solve the above problems, the purpose of the present invention is to provide a modular mold for precast concrete components to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model proposes a modular mold for precast concrete components, comprising a mold base plate and a quick demoulding mechanism and an auxiliary support mechanism both mounted on the top of the mold base plate;

[0007] The quick demoulding mechanism includes a fixed enclosure fixed to one side of the top of the mold base plate, and movable enclosures are hingedly provided at both ends of the top of the fixed enclosure. A connecting groove is opened at one end of the top of the movable enclosure, and a first spring is fixedly provided on the inner wall of the connecting groove. Two fixed blocks are fixedly provided at the middle position of one side of the outer wall of the movable enclosure, a grip rod is rotatably provided between the two fixed blocks, and one end of the first spring is fixedly connected to one side of the grip rod, a retaining ring is rotatably provided at the lower end of the outer wall of the grip rod, and a limiting shaft is fixedly provided at the middle position of one side of the outer wall of the mold base plate.

[0008] In one example, a plurality of second springs are fixedly provided at equal distances on one side of the inner wall of the movable enclosure, and a side plate is fixedly provided at one end of each of the second springs.

[0009] In one example, a sealing gasket is fixedly provided at the bottom of the movable enclosure, and rollers are rotatably provided at the four corners of the bottom of the mold base.

[0010] In one example, the auxiliary support mechanism includes a slot provided in the middle of one side of the inner wall of the fixed enclosure, and a support pad is rotatably provided at the edge of the other side of the top of the mold bottom plate.

[0011] In one example, the outer wall of one end of the support pad contacts the inner wall of the fixed enclosure, and a clamping block is fixedly provided at the edge of one side of the support pad.

[0012] In one example, the outer wall of the card block is interlaced with the inner wall of the card slot, and an arc-shaped pull ring is fixedly provided on one side of the top of the card block.

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-4 A modular mold for precast concrete components shown includes a mold base plate 1 and a quick demoulding mechanism 2 and an auxiliary support mechanism 5 both mounted on the top of the mold base plate 1;

[0024] The quick demoulding mechanism 2 includes a fixed panel 201 fixed to one side of the top of the mold base plate 1, and movable panels 202 are hinged at both ends of the top of the fixed panel 201. A connecting groove 203 is opened at one end of the top of the movable panel 202, and a first spring 204 is fixed on the inner wall of the connecting groove 203. Two fixed blocks 205 are fixed in the middle position of one side of the outer wall of the movable panel 202. A gripping rod 206 is rotatably provided between the two fixed blocks 205, and one end of the first spring 204 is connected to one end of the gripping rod 206. The side is fixedly connected, and a retaining ring 207 is rotatably provided at the lower end of the outer wall of the grip rod 206. A limiting shaft 208 is fixedly provided in the middle position of one side of the outer wall of the mold base plate 1, and the elastic pulling force of the first spring 204 on the grip rod 206 is sufficient to pull it and clamp the retaining ring 207 on the limiting shaft 208, thereby fixing the movable enclosure 202 on the mold base plate 1 and flush with the fixed enclosure 201. At the same time, the mold is provided with the mold base plate 1 to ensure that the molding bottom surface is flat, and there is no need to select a smooth and flat ground for placing the mold.

[0025] A plurality of second springs 209 are fixedly provided at equal intervals on one side of the inner wall of the movable enclosure 202. A side plate 210 is fixedly provided at one end of each second spring 209. When the movable enclosure 202 is being demoulded, the precast concrete member will squeeze the side plate 210 when the movable enclosure 202 rotates, thereby compressing the second spring 209, causing the side plate 210 to shrink a certain distance. The concrete will not squeeze the movable enclosure 202, making it impossible to demould.

[0026] Furthermore, a sealing gasket 3 is fixedly provided at the bottom of the movable enclosure 202, and rollers 4 are rotatably provided at the four corners of the bottom of the mold base plate 1. When pouring concrete, the sealing gasket 3 is provided at the bottom of the movable enclosure 202 to achieve sealing at the gap to prevent concrete from seeping out, and the rollers 4 are installed on the mold base plate 1 to facilitate pulling the mold base plate 1 to change its position;

[0027] Furthermore, the auxiliary support mechanism 5 includes a card slot 501 opened in the middle position of one side of the inner wall of the fixed enclosure 201, and a support pad 502 is rotatably provided at the edge of the other side of the top of the mold base plate 1. The support pad 502 is rotatably installed on the mold base plate 1. When some prefabricated components are adhered and fixed to the fixed enclosure 201, the rotating support pad 502 makes demoulding more convenient and quick, and plays a role in assisting demoulding.

[0028] The outer wall of one end of the support pad 502 contacts the inner wall of the fixed enclosure 201, and a clamping block 503 is fixed at the edge of one side of the support pad 502. When the clamping block 503 is inserted into the clamping slot 501, its outer side is flush with the inner wall of the fixed enclosure 201.

[0029] The outer wall of the block 503 is connected to the inner wall of the slot 501 through an interlaced connection, and an arc-shaped pull ring 504 is fixed on one side of the top of the block 503. The arc-shaped pull ring 504 is provided so that it has a force point when the rotating support plate 502 is demoulded, making it more convenient to rotate it upright.

[0030] Working principle: When using the modular mold for precast concrete components in this design, first rotate the movable panel 202 on the fixed panel 201 so that it is placed horizontally on the mold base 1, and rotate the grip 206 to rotate the clamping ring 207 at the lower end and sleeve it on the outer wall of the limiting shaft 208. Then, release the grip 206. Under the elastic action of the first spring 204 in the connecting groove 203, the grip 206 rebounds and clamps the clamping ring 207 on the limiting shaft 208. The movable panel 202 is pulled to be fixed by the pushed-out part at the bottom of the limiting shaft 208. After the concrete is injected into the mold base 1 and solidified, rotate it again. The gripping rod 206 allows the retaining ring 207 to fall off from the limiting shaft 208, thereby releasing the fixation of the movable enclosure 202. The movable enclosure 202 can be rotated open to perform demoulding. The staff does not need to bend over during the entire operation process, which makes it easier to demould large quantities of molds and reduces the workload. If one side of the prefabricated concrete component is stuck to the inner wall of the fixed enclosure 201 after the movable enclosure 202 is opened, the arc-shaped pull ring 504 can be pulled to pull the block 503 out of the slot 501, thereby causing the support pad 502 to rotate and tilt, causing the prefabricated component at the upper end to slide automatically, which can assist in supporting the prefabricated component and demoulding it.

[0031] The various embodiments in this specification are described in a progressive manner. Similar parts between the various embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are generally similar to the method embodiments, so the description is relatively simple. For relevant parts, refer to the description of the method embodiments.

[0032] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
