Description

Technical Field

[0001] This utility model belongs to the field of precast concrete component technology, and more specifically, it relates to a rapid assembly mold for precast concrete components with a grout leakage prevention structure. Background Technology

[0002] In the production of precast concrete components, molds are key equipment for ensuring the dimensional accuracy and appearance quality of the components. A rapid assembly mold for precast concrete components is needed during the prefabrication process. Existing rapid assembly molds for precast concrete components mainly consist of a base plate and side plates. The assembly method typically involves fixing four side plates to the upper perimeter of the base plate with bolts to form a square structure. The four side plates are then secured with bolts to ensure the overall stability of the mold.

[0003] Existing application number CN202122659898.1 discloses a precast concrete component mold, including a mold body, a first reinforcing frame connected to the top outer side of the mold body, a second reinforcing frame connected to the outer side of the mold body, a reinforcing seat connected to the bottom end of the mold body, and several reinforcing columns connected to the outer side of the mold body, with equal spacing between the reinforcing columns. A base plate is connected to the inner side of the mold body, and a fixing seat is installed at the bottom end of the mold body. A first threaded rod is connected to the inner side of the fixing seat, a bearing is fitted at one end of the first threaded rod, a bearing seat is fitted on the outer side of the bearing, one side of the bearing seat is connected to the bottom end of the base plate, and a second threaded rod is connected to the other end of the first threaded rod, with a knob connected to one end of the second threaded rod. This precast concrete component mold has a simple and reasonable structure, novel design, and is easy and convenient to operate. It can effectively facilitate demolding by workers, improve production efficiency, and has high mold strength, thus possessing high practical value.

[0004] Based on the above, existing rapid assembly molds for precast concrete components mostly rely on bolts for fastening the connections between parts. If these bolts become loose, gaps will form between the components, easily leading to grout leakage. Furthermore, after the concrete component is formed, it is prone to sticking to the side panels, making demolding extremely inconvenient. In actual production, demolding often requires using a sledgehammer to strike the side panels, a process that can easily damage the concrete component and affect the quality of the finished product. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a rapid assembly mold for precast concrete components with an anti-grout leakage structure. This solves the problem that existing rapid assembly molds for precast concrete components often rely on bolts for connection between components. If these bolts loosen, gaps will form between components, easily leading to grout leakage. Furthermore, after molding, the concrete component is prone to sticking to the side panels, making demolding extremely inconvenient. In actual production, demolding often requires striking the side panels with a sledgehammer, a process that can easily damage the concrete component and affect the quality of the finished product.

[0006] The purpose and effectiveness of this utility model's rapid assembly mold for precast concrete components with anti-grout leakage structure are achieved through the following specific technical means:

[0007] A rapid assembly mold for precast concrete components with a grout leakage prevention structure includes a base plate, right-angle fixing plates, guide cylinders, mold side plates, snap-fit ​​blocks, a leak-proof component, and a demolding component. Four sets of right-angle fixing plates are bolted to the four corners of the base plate. Multiple sets of guide cylinders are fixedly installed on the outside of the four sets of right-angle fixing plates. Four sets of mold side plates are provided, each set snapping into the middle of two adjacent sets of right-angle fixing plates. Eight sets of snap-fit ​​blocks are provided, with each pair of snap-fit ​​blocks fixedly connected to the left and right sides of one set of mold side plates. The leak-proof component is located on the upper part of the base plate. The demolding component is located inside the right-angle fixing plates.

[0008] Furthermore, the leak-proof component includes: a first annular groove and a first sealing strip, wherein the first annular groove is formed inside the base plate; and the first sealing strip is embedded inside the first annular groove.

[0009] Furthermore, the leak-proof component also includes: a snap-fit ​​groove, a second annular groove, and a second sealing strip. The snap-fit ​​groove is provided in eight sets, with each pair of snap-fit ​​grooves being opened at the two right-angled apex positions of a set of right-angled fixing plates. The second annular groove is provided in eight sets, with each pair of second annular grooves being opened at the two right-angled apex positions of a set of right-angled fixing plates. The second sealing strip is provided in eight sets, with the eight sets of second sealing strips embedded inside the eight sets of second annular grooves.

[0010] Furthermore, the leak-proof component also includes: a third annular groove and a third sealing strip. The third annular groove is provided in eight sets, and the eight sets of the third annular groove are respectively opened inside the eight sets of snap-fit ​​blocks. The third sealing strip is provided in eight sets, and the eight sets of the third sealing strip are respectively embedded inside the eight sets of snap-fit ​​blocks.

[0011] Furthermore, the leak-proof component also includes: a first connecting hole and a second connecting hole, wherein multiple sets of the first connecting holes are provided, and multiple sets of the first connecting holes are opened on the two outer sides of the right angle fixing plate; multiple sets of the second connecting holes are provided, and multiple sets of the second connecting holes are opened inside the eight sets of snap-fit ​​blocks.

[0012] Furthermore, the demolding assembly includes: guide rods and buffer pads, wherein multiple sets of guide rods are provided and the multiple sets of guide rods are slidably connected inside multiple sets of guide cylinders; multiple sets of buffer pads are provided and the multiple sets of buffer pads are fixedly installed on the top of the multiple sets of guide rods.

[0013] Furthermore, the demolding assembly also includes: a separation plate and connecting rods. The separation plate is provided in multiple sets, and the multiple sets of separation plates are slidably connected in the horizontal direction inside eight sets of snap-fit ​​grooves. The connecting rod is provided in multiple sets, with one end of the multiple sets of connecting rods hinged to the end of the guide rod, and the other end of the multiple sets of connecting rods hinged inside the separation plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this invention features a leak-proof component. A first annular groove is created inside the base plate, and a first sealing strip is embedded within it, forming a basic seal at the joint between the base plate and the mold side plate. Simultaneously, a snap-fit ​​groove and a second annular groove are created at the right-angle apex of the right-angle fixing plate, respectively cooperating with a snap-fit ​​block and a second sealing strip. This constructs multiple lines of sealing from the joint between the mold side plate and the right-angle fixing plate, and from the engagement of the snap-fit ​​block and the snap-fit ​​groove. Furthermore, bolts are used to tighten the components through the first and second connecting holes, ensuring a tighter fit. This multi-layered sealing structure significantly reduces the risk of grout leakage, ensuring the quality of the precast components and minimizing material waste and subsequent repair costs caused by grout leakage.

[0016] Secondly, this invention features a demolding assembly. A guide rod slides within a guide cylinder, and a buffer pad cushions the impact force. A connecting rod drives the separation plate to slide horizontally within the snap-fit ​​groove, precisely ejecting the snap-fit ​​block and achieving rapid separation of the right-angle fixing plate from the mold side plate. Furthermore, multiple separation plates within each snap-fit ​​groove apply force in stages, first pushing the center and then the sides, ensuring even force distribution on the snap-fit ​​block and preventing damage to the mold or components due to uneven force. This eliminates the need for violent hammering, resulting in high efficiency and no damage, improving demolding convenience and component yield.

[0017] This invention has the advantages of preventing grout leakage, facilitating demolding, and reducing component damage. The multiple sealing structures work together to significantly reduce the risk of grout leakage. Moreover, demolding can be completed without directly striking the mold or component with a sledgehammer, ensuring both demolding convenience and component safety. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] This utility model provides a quick assembly mold for precast concrete components with a grout leakage prevention structure, including a base plate 1, right-angle fixing plates 2, guide cylinders 3, mold side plates 4, snap-fit ​​blocks 5, and a leak-proof component. Four sets of right-angle fixing plates 2 are bolted to the four corners of the base plate 1. Multiple sets of guide cylinders 3 are fixedly installed on the outside of the four sets of right-angle fixing plates 2. Four sets of mold side plates 4 are provided, each set snapping into the middle of two adjacent sets of right-angle fixing plates 2. Eight sets of snap-fit ​​blocks 5 are provided, with each pair of snap-fit ​​blocks 5 fixedly connected to the left and right sides of a set of mold side plates 4. The leak-proof component is located on the upper part of the base plate 1.

[0028] The leak-proof component includes a first annular groove 101 and a first sealing strip 102. The first annular groove 101 is formed inside the base plate 1, and the first sealing strip 102 is embedded inside the first annular groove 101.

[0029] The leak-proof component also includes: a snap-fit ​​groove 201, a second annular groove 202, and a second sealing strip 203. The snap-fit ​​groove 201 is provided in eight sets, with each pair of snap-fit ​​grooves 201 being opened at the two right-angled tops of a set of right-angled fixing plates 2. The second annular groove 202 is provided in eight sets, with each pair of second annular grooves 202 being opened at the two right-angled tops of a set of right-angled fixing plates 2. The second sealing strip 203 is provided in eight sets, with the eight sets of second sealing strips 203 embedded inside the eight sets of second annular grooves 202.

[0030] The leak-proof component also includes: a third annular groove 502 and a third sealing strip 503. The third annular groove 502 is provided in eight sets, and the eight sets of third annular grooves 502 are respectively opened inside the eight sets of snap-fit ​​blocks 5; the third sealing strip 503 is provided in eight sets, and the eight sets of third sealing strips 503 are respectively embedded inside the eight sets of snap-fit ​​blocks 5.

[0031] The leak-proof component also includes: a first connecting hole 204 and a second connecting hole 501. The first connecting hole 204 is provided in multiple sets, and the multiple sets of first connecting holes 204 are opened on the two outer sides of the right angle fixing plate 2. The second connecting hole 501 is provided in multiple sets, and the multiple sets of second connecting holes 501 are opened inside the eight sets of snap-fit ​​blocks 5.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In practical applications, the snap-fit ​​block 5 of the mold side plate 4 is first precisely inserted into the snap-fit ​​groove 201 of the right-angle fixing plate 2. The matching snap-fit ​​structure between the snap-fit ​​block 5 and the snap-fit ​​groove 201 quickly achieves initial positioning and enhances the sealing of the joint through physical fitting. At this time, the first connecting hole 204 on the right-angle fixing plate 2 and the second connecting hole 501 in the snap-fit ​​block 5 automatically align. By inserting bolts into the aligned holes and tightening them, the rapid assembly of the mold side plate 4 and the right-angle fixing plate 2 can be completed.

[0034] In this manner, four sets of right-angle fixing plates 2 are sequentially spliced ​​with four sets of mold side plates 4 to form a four-sided mold structure. Subsequently, the four-sided mold is fixed to the upper part of the base plate 1 using bolts to construct the complete mold body.

[0035] In this assembled state, the first sealing strip 102 embedded in the first annular groove 101 inside the base plate 1 can form a continuous seal at the joint between the base plate 1 and the four molds, preventing concrete slurry from seeping down; the second sealing strip 203 in the second annular groove 202 inside the right-angle fixing plate 2 further enhances the sealing effect of the joint surface between the right-angle fixing plate 2 and the mold side plate 4, avoiding lateral slurry leakage; the third sealing strip 503 configured in the third annular groove 502 on the snap-fit ​​block 5 seals and reinforces the key joint position where the snap-fit ​​block 5 snaps into the snap-fit ​​groove 201. The triple sealing structure works together to build a multi-dimensional anti-leakage system. Example

[0036] Based on Example 1, such as Figures 1 to 5 As shown, it also includes: a demolding assembly, which is disposed inside the right-angle fixing plate 2.

[0037] The demolding assembly includes: guide rods 301 and buffer pads 302. Multiple sets of guide rods 301 are provided, and multiple sets of guide rods 301 are slidably connected inside multiple sets of guide cylinders 3. Multiple sets of buffer pads 302 are provided, and multiple sets of buffer pads 302 are fixedly installed on the top of multiple sets of guide rods 301.

[0038] The demolding assembly also includes: a separation plate 304 and a connecting rod 303. Multiple sets of separation plates 304 are provided, and the multiple sets of separation plates 304 are slidably connected in the horizontal direction inside the eight sets of snap-fit ​​grooves 201. Multiple sets of connecting rods 303 are provided, with one end of the multiple sets of connecting rods 303 hinged to the end of the guide rod 301, and the other end of the multiple sets of connecting rods 303 hinged inside the separation plate 304.

[0039] The specific usage and function of this embodiment are as follows:

[0040] When precast concrete components are formed and the right-angle fixing plate 2 needs to be separated from the mold side plate 4 to complete demolding, the following procedure should be followed: First, remove the fastening bolts at each joint of the mold to release the connection constraints of the mold body. Second, use a blunt object to gently tap the buffer pad 302. Utilize the elastic buffering characteristics of the buffer pad 302 to smoothly transmit the impact force to the guide rod 301. Under the action of external force, the guide rod 301 slides precisely along the axial channel of the guide cylinder 3. The guide cylinder 3 provides stable guidance for the guide rod 301, ensuring its linear motion trajectory. Third, during the sliding process of the guide rod 301, the separation plate 304 is driven by the hinged connecting rod 303, allowing the separation plate 304 to slide smoothly along the horizontal slide of the locking groove 201. The groove structure of the locking groove 201 provides guidance for the separation plate 304, ensuring its accurate displacement direction. As the separation plate 304 moves, it gradually pushes out the locking block 5 embedded in the locking groove 201, achieving rapid and non-destructive separation of the right-angle fixing plate 2 from the mold side plate 4.

[0041] For each set of snap-fit ​​slots 201, at least three sets of separation plates 304 are configured. To avoid uneven force on the snap-fit ​​block 5, the separation plate 304 in the middle position inside the snap-fit ​​slot 201 is driven first to break the central constraint of the snap-fit ​​block 5. Then, the separation plates 304 on the upper and lower sides of the snap-fit ​​slot 201 are driven in sequence. By applying force at multiple points and in steps, the snap-fit ​​block 5 is evenly disengaged from the snap-fit ​​slot 201. This ensures demolding efficiency and avoids damage to the snap-fit ​​block 5 or the mold side plate 4 due to concentrated force. It achieves efficient and stable separation between the right-angle fixing plate 2 and the mold side plate 4, and helps the precast components to be completely demolded.
