Description

Technical Field

[0001] This utility model relates to the field of cement pouring equipment technology, specifically to a sealing edge structure for a cement precast foundation mold that prevents grout leakage. Background Technology

[0002] Precast concrete components are cement concrete structures pre-cast in a factory environment. Their core characteristics are standardized production, controllable quality, and efficient construction. Manufactured under controlled factory conditions, precast components ensure higher precision, strength, and durability, while significantly reducing on-site wet work, shortening construction time, reducing noise and dust pollution, and saving material waste. The precast component manufacturing process involves injecting cement slurry into standard molds, curing it to achieve the required strength, unmolding the cast component, and then transporting it to the construction site for rapid installation. Traditional precast component molds are typically open-type for easy casting. While simple to use, these molds limit the structure of the precast components produced. When complex shapes are required, assembled molds must be used for casting. After the precast component solidifies, the molds are disassembled and the component is cast again. However, these molds are prone to grout leakage at the parting line during casting, which can cause contamination and affect the quality of the final product. A sealed structure is needed to solve these problems. Utility Model Content

[0003] To solve the above problems, this utility model proposes a sealing edge structure for a cement precast foundation mold that prevents grout leakage. It includes a semi-clip seat, with a wing plate at the head of the semi-cylindrical seat and a semi-circular disc connected to the tail. The end face of the semi-clip seat has a through hole, through which a tapping bolt is inserted to install the semi-clip seat on the perimeter of the mold closing opening. When the mold is closed, two corresponding semi-clip seats are assembled into a snap-fit ​​seat. The head shape of the snap-fit ​​seat matches the groove of the snap-fit. A sealing groove is opened on the inner side of the mold closing opening, and a sealing strip is embedded in the sealing groove. The slope surfaces of the sealing strips on both sides of the mold closing opening are matched.

[0004] Furthermore, the contact surface between the sealing strip and the sealing groove is provided with a protruding insert, which is embedded in the groove wall of the sealing groove.

[0005] Furthermore, the arch of the semi-cylindrical seat of the semi-locking seat is interference-fitted with the center circle of the groove.

[0006] Furthermore, the buckle has ear plates on both sides, and a rotating handle is connected to the ear plates. The groove ring has a thickened convex edge.

[0007] Furthermore, the mold's closing surface is equipped with mutually cooperating positioning and engaging rings.

[0008] Furthermore, double-sided adhesive tape is provided on the back of the semi-circular disc.

[0009] The beneficial effects of this utility model are as follows: The buckle in this utility model can rotate and lock the buckle seat assembled into a whole, thereby pressing the sealing strip in the sealing groove to achieve the sealing and mold closing of the mold. The sealing strip is inserted into the groove through the protruding insert, which can be quickly disassembled and assembled. The sealing strip is further improved by the bevel cooperation between the sealing strips. The two half buckles that make up the buckle seat are installed by tapping bolts. They can be quickly arranged on the edge as needed, which is convenient for addition, modification and maintenance. It has the characteristics of simple structure and strong applicability.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 3As shown, a sealing edge structure for a precast concrete foundation mold designed to prevent grout leakage includes a semi-locking seat 1. The semi-cylindrical seat 1 has a wing plate 101 at its head and a semi-circular disc 102 connected to its tail. Double-sided adhesive tape 104 is provided on the back of the semi-circular disc 102. A through hole 103 is opened on the end face of the semi-locking seat 1. A tapping bolt 2 passes through the through hole 103 to install the semi-locking seat 1 onto the perimeter 301 of the mold's closing opening. The mold's closing surface has mutually cooperating positioning and engaging rings 304. When the mold 3 is closed, two corresponding semi-locking seats 1 are assembled into a snap-fit ​​seat. The head shape of the snap-fit ​​seat matches the groove 401 of the snap-fit ​​seat 4. Ear plates are provided on both sides of the snap-fit ​​seat 4. 402, the ear plate 402 is connected to the rotating handle 403, the groove 401 is provided with a thickened protruding edge, the arch of the semi-cylindrical seat of the half buckle 1 is interference-fitted with the center circle of the groove 401, that is, the arch is more protruding than the other circumferences, so that the buckle 4 can press the mold 3 more tightly after locking. The mold 3 has a sealing groove 302 on the inner side of the mold opening, and a sealing strip 5 is embedded in the sealing groove 302. The contact surface between the sealing strip 5 and the sealing groove 302 is provided with a protruding insert 501. The protruding insert 501 is embedded in the groove channel 303 of the sealing groove 302. The protruding insert 501 and the groove 303 are interference-fitted, and the slope surfaces of the sealing strip 5 on both sides of the mold opening are matched.

[0015] The working principle of this utility model is as follows: The upper and lower molds 3 are precisely closed by the interlocking ring 304. The double-sided tape 104 is torn off, and several half-buckles 1 are to be bonded to the upper and lower edges 301 as needed. If it is to be installed at the corner or rounded corner of the mold, the edge 301 at that location is chamfered. After positioning, each half-buckle 1 is locked by the tapping bolt 2. When it is necessary to pour the mold 3, the buckle 4 is to be snapped into the buckle seat through the groove 401. The buckle 4 is rotated 90 degrees to make the sealing strip 5 seal and lock the mold closure line inside the mold 3. Cement slurry is poured through the riser on the mold 3. After the cement dries, the buckle 4 is unscrewed, the upper and lower molds 3 are separated and the mold is poured. When it is necessary to replace the sealing strip 5, it is directly pulled out from the sealing groove 302.

[0016] The buckle 4 in this utility model can rotate and lock the buckle seat assembled into a whole, thereby pressing the sealing strip 5 in the sealing groove 302 to achieve the sealing and mold closing of the mold 3. The sealing strip 5 is inserted into the groove 303 through the protruding insert 501, which can be quickly disassembled and assembled. The sealing strip 5 is further improved by the bevel fit between them. The two half buckle seats 1 that make up the buckle seat are installed by the tapping bolts 2. They can be quickly arranged on the edge 301 as needed, which is convenient for addition, modification and maintenance. It has the characteristics of simple structure and strong applicability.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
