Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated beams, and more specifically, to a combined mold for pouring prefabricated concrete parts. Background Art

[0002] Precast concrete components are manufactured in factories using standardized, mechanized processes. They eliminate the need for on-site pouring, significantly reducing dust and noise pollution. They are widely used in construction, transportation, water conservancy, and other fields.

[0003] Concrete precast parts require special molds. Chinese utility model patent application number 202420512708.4 discloses a modular mold for concrete precast components that is easy to assemble and disassemble. The transmission bolt connection is changed to a snap-on connection, which is convenient for disassembly and assembly while ensuring the joint strength. However, this connection method needs to be performed for each connection surface. When the combined mold has more connection surfaces, the number of snaps that need to be tightened increases, affecting the operation speed. In addition, when producing large precast panels, the mold may be deformed due to concrete extrusion, which ultimately causes the precast parts to deform. Utility Model Content

[0024] See also Figure 1-5 , the utility model provides the following technical solutions:

[0025] A modular mold for pouring precast concrete parts includes a bottom plate 1, on which are placed a plurality of lower vertical plates 2, which are arranged in a rectangular frame shape. Upper vertical plates 3 are placed correspondingly on the lower vertical plates 2, and a plurality of steel bar reserved holes 8 are formed at the junction of the lower vertical plates 2 and the upper vertical plates 3. A top plate 4 is placed on the upper vertical plates 3. The bottom plate 1, the lower vertical plates 2, the upper vertical plates 3 and the top plate 4 form a complete cavity for pouring concrete.

[0026] The middle gland of the top plate 4 has a pressing plate 5. The pressing plate 5 increases the strength of the middle position of the top plate 4, making the top plate 4 not easily deformed when subjected to the expansion force of concrete solidification, thus ensuring the surface quality of concrete solidification and improving the finished product quality.

[0027] A number of clamping mechanisms 7 are installed on the bottom plate 1. The clamping mechanisms 7 are clamped with the top plate 4. By pressing the top plate 4 and the bottom plate 1 against each other, the lower vertical plate 2 and the upper vertical plate 3 therebetween are also pressed against each other, and the whole mold is formed, without the need to use connecting parts to fix each connection surface. Especially in the case of a large number of mold assemblies, the disassembly and assembly operations are simplified and it is convenient to use.

[0028] The cross-sections of the lower vertical plate 2 and the upper vertical plate 3 are both in the shape of "匚". One side of the lower vertical plate 2 connected to the bottom plate 1 is the bottom contact surface 21, and one side of the upper vertical plate 3 connected to the top plate 4 is the top contact surface 31. The other end surface of the lower vertical plate 2 abuts against the corresponding end surface of the upper vertical plate 3, increasing the contact area between each connection surface and ensuring the stable placement of each structure during installation.

[0029] An installation groove 11 is provided on the bottom plate 1. The bottom contact surface 21 is correspondingly arranged in the installation groove 11. The installation groove 11 can limit the lower vertical plate 2, that is, it ensures the standardization of the enclosure structure of the lower vertical plate 2 and the stability of the placement of the lower vertical plate 2. The upper surface of the bottom contact surface 21 is flush with the upper surface of the bottom plate 1. A number of limiting mechanisms 6 are provided on the bottom plate 1. The limiting mechanisms 6 abut against the upper surface of the bottom contact surface 21.

[0030] The limiting mechanism 6 includes a slide rail 61. The slide rail 61 is fixed on the bottom plate 1. A limiting block 62 is slidably connected in the slide rail 61. The limiting block 62 can slide onto the bottom contact surface 21 and abut against the bottom contact surface 21. A push rod 63 is provided on the limiting block 62. By pushing the push rod 63, the limiting block 62 can be带动 to slide in the slide rail 61. When the limiting block 62 covers and presses on both the bottom plate 1 and the bottom contact surface 21 at the same time, the limiting mechanism 6 and the installation groove 11 cooperate to fix the lower vertical plate 2 on the bottom plate 1, thereby improving the overall connection strength of the mold.

[0031] The clamping mechanism 7 includes a mounting block 71. The mounting block 71 is fixed on the bottom plate 1. A rotating shaft 72 is connected to the mounting block 71. A connecting rod 73 is rotatably connected to the rotating shaft 72. A second clamping block 77 is provided at the free end of the connecting rod 73. A second clamping groove 75 is correspondingly arranged on the side of the top plate 4. The second clamping groove 75 is formed by an "L" - shaped plate and the top plate 4 together. The second clamping groove 75 is open on one side. When the connecting rod 73 rotates into the second clamping groove 75, the second clamping block 77 rotates above the "L" - shaped plate and is clamped with the "L" - shaped plate, thereby pressing the top plate 4 and the bottom plate 1 against each other, that is, fixing the bottom plate 1, the lower vertical plate 2, the upper vertical plate 3 and the top plate 4 together.

[0032] On the side surface of the top connection surface 31, a number of first clamping grooves 74 are provided. The first clamping grooves 74 have the same structure as the second clamping grooves 75. The number of first clamping grooves 74 and the number of second clamping grooves 75 are arranged at corresponding intervals along the same vertical direction. A first clamping block 76 is provided on the connecting rod 73. The first clamping block 76 can be correspondingly clamped with the first clamping groove 74, so that the upper vertical plate 3 is clamped with the bottom plate 1, enhancing the clamping force of the clamping mechanism 7 between the various structures and ensuring the connection strength of the various structures.

[0033] Specifically, a pressing plate 5 is provided at the middle position of the top plate 4, increasing the strength of the middle part of the top plate 4, so that the top plate 4 will not be deformed by the extrusion of the concrete solidification expansion, ensuring the surface flatness of the concrete precast member and improving the finished product quality.

[0034] The cross-sections of the lower vertical plate 2 and the upper vertical plate 3 are both in the shape of "匚". The bottom connection surface 21 of the lower vertical plate 2 is placed in the installation groove 11 of the bottom plate 1. One side of the upper vertical plate 3 abuts against the lower vertical plate 2, and the other side is connected to the top plate 4. The bottom plate 1 and the top plate 4 are directly connected through the clamping mechanism 7. The connecting rod 73 of the clamping mechanism 7 is rotatably installed on the bottom plate 1. A second clamping block 77 is provided at the free end of the connecting rod 73. A second clamping groove 75 is correspondingly provided on the top plate 4. When the connecting rod 73 is rotated so that the second clamping block 77 is clamped with the second clamping groove 75, the top plate 4 is pulled downward and pressed by the clamping mechanism 7, thus ensuring that the bottom plate 1, the lower vertical plate 2, the upper vertical plate 3 and the top plate 4 are mutually pressed, and there is no need to fix each connection surface separately, which is convenient to operate.
