Description

Technical Field

[0001] This utility model belongs to the field of cement mold technology, specifically, it relates to a cement precast mold. Background Technology

[0002] Cement precast products, also known as cement components, are short for precast concrete structures. They mainly include cement colored bricks, cement pipe fittings, cement covers, irregularly shaped cement components, curb stones, and retaining wall manhole covers. Using cement components can shorten the construction cycle of construction projects and save project costs. They are widely used in municipal road construction, water supply and drainage construction, or civil engineering construction.

[0003] Chinese utility model patent CN221850598U discloses a cement precast product mold, comprising: a base, with pillars at all four ends of the top of the base, and a base plate connected to the top of the four pillars; and a mold frame, comprising two first side plates and two second side plates staggered on the four sides of the base plate. This utility model, by setting up a mold frame and a base plate to form a mold container, and with the cooperation of a clamping arm, a fixing component, a first movable plate, and a second movable plate, can stably splice the first and second side plates onto the four sides of the base plate, thereby forming a sturdy mold container. Furthermore, after the cement precast product has solidified, the first and second side plates can be rotated and separated to disassemble the entire mold frame, allowing workers to directly remove the cement precast product from the base plate. The operation is simple and convenient, saving time and effort, and greatly improving the effectiveness of the device.

[0004] Although the mold can be fixed between the two side plates by clamping arms, this fixing method cannot provide a large fixing force between the two adjacent side plates. As a result, during the subsequent pouring process, concrete is prone to leaking out and affecting the cement forming effect. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that although the mold can be fixed between the two side plates by clamping arms, this fixing method cannot provide a large fixing force between the two adjacent side plates, which can easily lead to concrete leakage during subsequent pouring and affect the cement forming effect, the present invention adopts the following technical solution.

[0007] A precast concrete mold includes a mold base plate, with rotating shafts rotatably connected to the outer walls of the mold base plate. Each rotating shaft has an installation side plate fixedly connected to its outer wall, and a fixed lifting lug is fixedly connected to the upper end of each installation side plate. A fixed bracket is provided at the bottom of the mold base plate, and a clamping assembly is installed on the outer wall of the fixed bracket. The clamping assembly can clamp the installation side plate in a vertical position.

[0008] Preferably, an adjustment component is installed between the clamping component and the fixed bracket, the adjustment component being able to adjust the distance between the clamping component and the fixed bracket.

[0009] Preferably, a fixing component is installed between adjacent mounting side panels, which can fix the mounting side panels after they are attached.

[0010] Preferably, the clamping assembly includes a second U-shaped frame, an internally threaded sleeve, a hexagonal head, a threaded rod, a plug pin, a first U-shaped frame, and a rotating block. The second U-shaped frame is rotatably connected to a mounting base, and the internally threaded sleeve is rotatably connected to the mounting base. A hexagonal head is fixedly connected to the outer wall of the end of the internally threaded sleeve, and a threaded rod is threadedly connected to the internal thread of the internally threaded sleeve. The outer wall of the mounting side plate near the upper end is detachably connected to a first U-shaped frame with an outward opening. The first U-shaped frame is rotatably connected to a rotating block, and the threaded rod is plugged into the rotating block. A plug pin is plugged into the rotating block, and the plug pin fixes the threaded rod.

[0011] Preferably, the adjustment components include, but are not limited to, fastening bolts and sliding rods. The outer wall of the fixed bracket is slidably connected to the sliding rods, the ends of which are detachably connected to the second U-shaped frame. One end of each sliding rod inserted into the fixed bracket is fixedly connected to a limiting plate. The upper end of the fixed bracket is threadedly connected to a fastening bolt, and the threaded end of the fastening bolt contacts the outer wall of the sliding rod.

[0012] Preferably, the bottom of the mold base plate is fixedly connected to multiple support columns, which are inserted into a fixed bracket. The outer wall of the fixed bracket is fixedly connected to a fixed angle iron, and the fixed angle iron is fixed to the ground by anchor bolts.

[0013] Preferably, the fixing assembly includes an angle iron plate, a limiting sealing plate, and a connecting top plate. The outer walls of two adjacent mounting side plates are provided with insertion limiting grooves. The limiting sealing plate is inserted into the inside of the insertion limiting groove. The top plate is fixedly connected to the top of the limiting sealing plate, and the angle iron plate is fixedly connected to the bottom of the connecting top plate. The angle iron plate is attached to the outer edge of the adjacent mounting side plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By using the clamping assembly, rotating the hexagonal head causes the internal threaded sleeve to rotate, which in turn allows the threaded rod to extend outward. This, combined with the rotation of the rotating block and the internal threaded sleeve, causes each mounting side plate to rotate to a vertical position. This ensures that there is a tight fit between the mounting side plate and the adjacent mounting side plate, preventing leakage during concrete pouring.

[0016] 2. Through the adjustment component, the sliding connection between the sliding rod and the fixed bracket allows the second U-shaped frame to move outward to adjust its position. By rotating the fastening bolt, the position of the second U-shaped frame can be fixed. When not in use, each second U-shaped frame is pressed against the outer wall of the fixed bracket, thereby reducing the footprint of the clamping component.

[0017] 3. By using the fixed components, after each mounting side plate is clamped by the clamping components, a limiting sealing plate is inserted into the insertion limiting groove between every two mounting side plates, thereby fixing multiple mounting side plates together. Then, the mold is poured, and after there is no leakage, the mold can be removed. The clamping components can clamp the mounting side plates on the next mold, which can reduce production costs.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1 As shown, this is a schematic diagram of a preferred embodiment of the present invention for a cement precast mold. The cement precast mold of this embodiment includes a mold base plate 100. Rotating shafts 101 are rotatably connected to the outer wall of the mold base plate 100. An installation side plate 102 is fixedly connected to the outer wall of each rotating shaft 101. A fixing lug 103 is fixedly connected to the upper end of each installation side plate 102. In this embodiment, each installation side plate 102 rotates and fits against the adjacent installation side plate 102, so that concrete is poured onto the upper end of the mold base plate 100, thereby forming the cement.

[0030] like Figure 2As shown, this is a schematic diagram of the clamping assembly structure in this embodiment. A fixed bracket 200 is provided at the bottom of the mold base plate 100. A sliding rod 201 is provided on the outer wall of the fixed bracket 200. A second U-shaped frame 202 with an opening facing the mounting side plate 102 is detachably connected to the end of the sliding rod 201. A mounting seat is rotatably connected inside the second U-shaped frame 202. An internally threaded sleeve 203 is rotatably connected to the mounting seat. A hexagonal head 204 is fixedly connected to the outer wall of the end of the internally threaded sleeve 203. A threaded rod 205 is threadedly connected inside the internally threaded sleeve 203. A first U-shaped frame 104 with an outward opening is detachably connected to the outer wall of the mounting side plate 102 near the upper end. The first U-shaped frame 104 has a rotating block 105 internally connected to it. The threaded rod 205 is inserted into the rotating block 105. The rotating block 105 has a pin 206 inserted into it, which fixes the threaded rod 205. In this embodiment, by rotating the hexagonal head 204, the internal threaded sleeve 203 is rotated, which allows the threaded rod 205 to extend outward. With the rotation of the rotating block 105 and the rotation of the internal threaded sleeve 203, each mounting side plate 102 is rotated to a vertical state. This ensures that there is a tight fit between the mounting side plate 102 and the adjacent mounting side plate 102, preventing leakage during concrete pouring.

[0031] It is worth noting that the second U-shaped frame 202, the internal threaded sleeve 203, the hexagonal head 204, the threaded rod 205, the plug pin 206, the first U-shaped frame 104, and the rotating block 105 mentioned above are clamping components in this embodiment. The clamping components include, but are not limited to, the second U-shaped frame 202, the internal threaded sleeve 203, the hexagonal head 204, the threaded rod 205, the plug pin 206, the first U-shaped frame 104, and the rotating block 105. Any component that can make multiple mounting side plates 102 fit together tightly can be used in this embodiment.

[0032] like Figure 3 As shown, this is a schematic diagram of the adjustment component structure in this embodiment. The sliding rod 201 is slidably connected to the outer wall of the fixed bracket 200. One end of each sliding rod 201 inserted into the fixed bracket 200 is fixedly connected to a limiting plate 207. The upper end of the fixed bracket 200 is threaded with a fastening bolt 208. The threaded end of the fastening bolt 208 contacts the outer wall of the sliding rod 201. In this embodiment, the sliding connection between the sliding rod 201 and the fixed bracket 200 allows the second U-shaped frame 202 to move outward to adjust its position. By rotating the fastening bolt 208, the position of the second U-shaped frame 202 can be fixed. When not in use, each second U-shaped frame 202 is pressed against the outer wall of the fixed bracket 200, thereby reducing the floor space occupied by the clamping component.

[0033] It is worth noting that the fastening bolt 208 and sliding rod 201 mentioned above are adjustment components in this embodiment. Adjustment components include, but are not limited to, fastening bolt 208 and sliding rod 201. Any component that can adjust the position of the second U-shaped frame 202 can be applied to this embodiment.

[0034] like Figure 3 As shown, a plurality of support columns 106 are fixedly connected to the bottom of the mold base plate 100. The support columns 106 are inserted into the fixed bracket 200. The outer wall of the fixed bracket 200 is fixedly connected to the fixed angle iron 209. Anchor bolts pass through the fixed angle iron 209 and fix it to the ground. In this embodiment, the fixed bracket 200 is installed between the mold base plate 100 and the support columns 106 are inserted into the fixed bracket 200. The fixed bracket 200 can be fixed to the ground by the anchor bolts.

[0035] like Figure 4 As shown, this is a schematic diagram of the fixing component structure in this embodiment. Two adjacent mounting side plates 102 have insertion limiting grooves 107 on their outer walls. A limiting sealing plate 301 is inserted into the insertion limiting groove 107. A connecting top plate 302 is fixedly connected to the top of the limiting sealing plate 301, and an angle iron plate 300 is fixedly connected to the bottom of the connecting top plate 302. The angle iron plate 300 fits against the outer edge of the adjacent mounting side plates 102. In this embodiment, after the clamping component clamps each mounting side plate 102, a limiting sealing plate 301 is inserted into the insertion limiting groove 107 between every two mounting side plates 102, thereby fixing multiple mounting side plates 102 together. Then, the mold is poured, and after there is no leakage, the mold can be removed. The clamping component can then clamp the mounting side plate 102 on the next mold, reducing production costs.

[0036] It is worth noting that the aforementioned angle iron plate 300, limiting sealing plate 301, and connecting top plate 302 are fixing components in this embodiment. Fixing components include, but are not limited to, angle iron plate 300, limiting sealing plate 301, and connecting top plate 302. Any component that can fix two adjacent mounting side plates 102 can be applied to this embodiment.
