Description

Technical Field

[0001] The utility model relates to the technical field of building profiles, in particular to a prefabricated arc-shaped concrete prefabricated component mould. Background Art

[0002] Precast curved concrete components are a special type of precast concrete component that combines elements of precast panels and curved designs, offering specific advantages and applications. These curved precast components are typically manufactured and processed in a precast plant, then transported directly to the construction site for installation. Compared to traditional precast components, precast curved components offer greater flexibility in design and use, adapting to diverse building requirements, particularly when a curved design is required.

[0003] Precast curved concrete component molds are tools used to produce curved precast components. They are manufactured using either plastic injection molding or steel molds. These molds are commonly used in road and bridge construction to produce slope protection or curbstones to meet specific shape requirements. Precast curved component molds can be made of either plastic or steel, depending on design requirements and production processes.

[0004] When using steel molds, the construction process of first supporting the mold and then installing the steel frame or the construction process of first installing the steel frame and then supporting the mold is often adopted; in the construction process of first installing the steel frame and then supporting the mold, the formwork process will inevitably collide with the steel frame, causing the position of the steel frame to shift, resulting in a decrease in the strength of the formed prefabricated components; while in the construction process of first supporting the mold and then installing the steel frame, after the mold is erected, the operating space for installing the steel frame will be very small, which may cause the steel frame to be positioned inaccurately, resulting in the strength of the finished prefabricated components not meeting the design requirements.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figures 1 to 7 As an embodiment of the present invention, the prefabricated arc-shaped concrete prefabricated component mold includes an inner wall 1 and side walls 101 fixedly installed on both sides of the inner wall 1. The inner wall 1 is also fixedly mounted with a base 102 fixedly connected to the side walls 101.

[0029] A rotating structure is provided on one of the side walls 101 , and the rotating structure is connected to the outer wall 2 ; the outer wall 2 can rotate on the side wall 101 through the rotating structure.

[0030] The base 102 is provided with a locking structure, and the locking structure can limit the outer wall 2 when the outer wall 2 rotates to interfere with the other side wall 101 .

[0031] The side wall 101 is also provided with a hoisting structure for transferring the mold.

[0032] In this embodiment, when in use, the outer wall 2 is rotated by the rotating structure to open the mold, and then the prefabricated steel frame is installed at the designed position and fixed to the base 102 and the side wall 101.

[0033] Then, the outer wall 2 is rotated by the rotating structure so that the outer wall 2 gradually approaches the inner wall 1 to close the mold; when the outer wall 2 conflicts with the side wall 101, the locking structure will automatically limit the outer wall 2 to prevent the outer wall 2 from being out of conflict with the side wall 101, thereby avoiding leakage or mold explosion during concrete pouring, thereby improving the practicality of the mold.

[0034] After the locking structure limits the outer wall 2, the mold is hoisted to the casting area through the hoisting structure using a hoisting device for casting and curing.

[0035] After the concrete strength reaches the design requirement, an external force is applied to the locking structure to make it contact the limit of the outer wall 2, thereby performing the mold-turning of the prefabricated part.

[0036] By cooperating with the rotating structure and the locking structure, the operating space in the mold is increased, thereby improving the production efficiency of the entire prefabricated curved floor slab. The locking structure can enhance the anti-seepage performance and strength of the mold, thereby avoiding leakage or mold explosion during concrete pouring, thereby improving the practicality of the mold. In the process of closing the mold, there will be no direct contact with the steel skeleton, thereby avoiding the situation where the position of the steel skeleton is offset and the strength of the finished floor slab does not meet the design requirements.

[0037] As a further solution of the present invention, the rotating structure includes a first connecting member 106 fixedly mounted on one of the side walls 101 , and a second connecting member 202 fixedly connected to the outer wall 2 is rotatably mounted on the first connecting member 106 .

[0038] In this embodiment, when in use, the locking structure is first released to limit the outer wall 2, and then an external force is applied to the outer wall 2 to rotate it away from the side wall 101. At this time, the second connecting member 202 will rotate with the first connecting member 106; the first connecting member 106 and the second connecting member 202 can support the outer wall 2 so that the position of the outer wall 2 will not shift during the rotation process, so that when the outer wall 2 is rotated to contact the side wall 101 again, the anti-permeability performance of the mold can be maintained to avoid the formation of gaps.

[0039] As a further solution of the present invention, the locking structure includes a fixed column 201 fixedly mounted on the outer wall 2, and a connecting rod 3 is rotatably mounted on the fixed column 201; a telescopic sleeve 4 is rotatably mounted on the base 102, and an engaging block 401 is slidably engaged in the telescopic sleeve 4, and a spring 402 fixedly connected to the telescopic sleeve 4 is fixedly connected to the engaging block 401; a telescopic column 5 that interferes with the engaging block 401 is slidably engaged in the telescopic sleeve 4; a slider 6 rotatably connected to the connecting rod 3 is rotatably mounted on the telescopic column 5; and a sliding groove 103 and a locking groove 104 that are slidably engaged with the slider 6 are provided on the base 102.

[0040] In this embodiment, during use, an external force is applied to the slider 6 to cause it to move from the locking groove 104 into the sliding groove 103. When the slider 6 moves from the locking groove 104 into the sliding groove 103, the slider 6 drives the telescopic column 5 to slide inward within the telescopic sleeve 4, thereby driving the engaging block 401 to slide inward within the telescopic sleeve 4, causing the spring 402 to be compressed. Then, when the outer wall 2 is rotated, the connecting rod 3 rotates on the fixed column 201, and at the same time, the connecting rod 3 drives the slider 6 to slide in the sliding groove 103 away from the locking groove 104, and the slider 6 and the connecting rod 3 rotate in coordination. As the slider 6 slides, it drives the telescopic column 5 to slide outward within the telescopic sleeve 4. At this time, the spring 402 gradually resets, driving the engaging block 401 to slide outward within the telescopic sleeve 4 until the elastic force of the spring 402 disappears. Thereafter, the telescopic column 5 continues to slide outward until the outer wall 2 rotates to its maximum angle.

[0041] After the steel frame is positioned and installed, an external force is applied to the outer wall 2 to rotate toward the side wall 101, and the outer wall 2 rotates toward the side wall 101. During the rotation, the outer wall 2 will drive the slider 6 to slide in the slide groove 103 toward the locking groove 104 through the connecting rod 3 (the external force acts on the slider 6 through the connecting rod 3, and the slide groove 103 and the slider 6 decompose the force so that the force pushing the slider 6 to slide is not in line with the connecting rod 3). During the sliding process, the slider 6 will drive the telescopic column 5 to slide inward in the telescopic sleeve 4, and will re-collide with the chimeric block 401. When the slider 6 slides to the connecting port of the slide groove 103 and the locking groove 104, the outer wall 2 and the side wall 101 are in close contact. At the same time, the elastic force of the spring 402 drives the mosaic block 401 to slide outward in the telescopic sleeve 4 and drives the telescopic column 5 to move synchronously. At this time, the slider 6 will be pushed into the locking groove 104. Through the mutual contact between the locking groove 104 and the slider 6, the outer wall 2 will be firmly restricted to the position of contact with the side wall 101.

[0042] By cooperating with the rotating structure and the locking structure, the operating space in the mold is increased, thereby improving the production efficiency of the entire prefabricated curved floor slab. The locking structure can enhance the anti-seepage performance and strength of the mold, thereby avoiding leakage or mold explosion during concrete pouring, thereby improving the practicality of the mold.

[0043] As a further solution of the present invention, the locking groove 104 is an arc groove, and the radius of its outer arc is the length of the outer arc wall from the axis of the fixing column 201 along the connecting rod 3 to the slider 6 away from the fixing column 201.

[0044] In this embodiment, when the slider 6 slides in the locking groove 104, the connecting rod 3 rotates on the fixed column 201; at this time, an external force is applied to the outer wall 2 to slide away from the side wall 101, and the external force acts on the slider 6 through the connecting rod 3. Due to the action of the locking groove 104 and the slider 6, the force acting on the slider 6 is always collinear with the connecting rod 3, and the slider 6 is limited by the inner groove wall of the locking groove 104, so that the outer wall 2 always remains in a state of conflict with the side wall 101.

[0045] As a further solution of the present invention, the lifting structure includes a fixing block 107 fixed on the side wall 101 , and a lifting ring 7 is rotatably mounted on the fixing block 107 .

[0046] In this embodiment, after the outer wall 2 is in close contact with the side wall 101, the lifting ring 7 is hooked with the hook of the lifting device to move the mold. During the lifting process, the lifting ring 7 will rotate and cooperate with the fixed block 107; the lifting structure can reduce the difficulty of moving the mold and improve production efficiency.

[0047] As a further solution of the present invention, a sealing block is fixed on the inner side of the side wall 101 for enhancing the sealing performance.

[0048] In this embodiment, the sealing block can increase the contact area between the side wall 101 and the outer wall 2, thereby improving the sealing after the outer wall 2 and the side wall 101 collide with each other, thereby preventing concrete leakage or even mold explosion during pouring and curing, and improving the practicality of the mold.

[0049] As a further solution of the present invention, ribs for increasing strength are fixedly installed on the inner arc wall of the inner wall 1 and the outer arc wall of the outer wall 2.

[0050] In this embodiment, the ribs can enhance the strength of the outer wall 2 and the inner wall 1, preventing deformation of the outer wall 2 and the inner wall 1 during concrete pouring, which would cause the formed curved floor slab to be unable to meet construction requirements, thereby improving the molding effect of the mold.

[0051] As a further solution of the present invention, a notch 105 is provided on the base 102 .

[0052] In this embodiment, when the outer wall 2 is in tight contact with the side wall 101 , the fixing column 201 will be located in the notch 105 , thereby improving the aesthetics of the mold.

[0053] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
