Description

Technical Field

[0001] This utility model relates to the field of building mold technology, specifically a concrete box culvert forming mold. Background Technology

[0002] Concrete box culverts are key drainage and passage structures in highway, municipal, and water conservancy projects. Their cross-sectional curvature needs to be flexibly designed according to geological conditions, drainage flow, and other requirements. With the promotion of prefabricated buildings and the deepening development of underground space, box culvert molds need to meet the requirements of multi-specification adaptability, high-precision molding, and efficient construction.

[0003] Traditional box culvert molds often have an integrated fixed structure for the inner arc section. If box culverts with different arcs need to be processed, the entire arc template needs to be replaced, resulting in insufficient mold versatility. Although some improved molds attempt to adjust the arc, they often use a complex structure of multi-segment splicing and bolt installation and disassembly. The adjustment process is time-consuming and laborious, and lacks temporary positioning and precise locking mechanisms, which can easily lead to arc deviations and thus make it difficult to guarantee the molding quality to a certain extent. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete box culvert molding mold, which solves the problems described in the background section above.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a concrete box culvert forming mold, including a base and a sliding component installed on the surface of the base, and also including an outer mold component, wherein the outer mold component is symmetrically installed on the sliding component, and an inner mold component is provided on the inner side of the outer mold component on the sliding component; A support component is disposed inside the inner mold assembly, and the inner mold assembly and the support component form a triangular structure to support the inner curvature of the inner mold assembly, thereby further improving the stability and applicability of the device.

[0006] As a preferred technical solution of this utility model, the sliding component includes a sliding groove formed on the surface of the base, a sliding rod fixedly installed in the sliding groove, and four sets of sliding blocks slidably installed on the sliding rod.

[0007] As a preferred embodiment of this utility model, an outer mold assembly is installed on the two sets of sliding blocks on the outer side, and an inner mold assembly is installed on the two sets of sliding blocks on the inner side.

[0008] As a preferred technical solution of this utility model, the outer mold assembly includes a column mold mounted on the sliding block, a corresponding groove is provided at one top end of the column mold, and a horizontal plate mold is installed inside the corresponding groove.

[0009] As a preferred technical solution of this utility model, the horizontal plate mold is provided with fixing holes at equal intervals, and a fixing component is provided on the corresponding groove at the position corresponding to the fixing hole.

[0010] As a preferred embodiment of the present invention, the fixing component includes a placement groove formed on one side of the corresponding groove, a fixing rod installed in the placement groove, and a spring fitted on the fixing rod in the placement groove.

[0011] As a preferred technical solution of this utility model, the inner mold assembly includes an inner mold plate installed on the inner sliding block, an arc plate one installed on the top of the inner mold plate, an arc plate two slidably installed on the outer side of the arc plate one, and a horizontal plate fixedly installed on one side of the arc plate two.

[0012] As a preferred technical solution of this utility model, the support component includes telescopic mounting rods symmetrically installed on the inner side of the inner mold plate, a fixing plate fixedly installed on the inner side of the horizontal plate, and fixing grooves evenly spaced on the fixing plate. The telescopic mounting rods are inserted into the fixing grooves and form a triangular structure with the telescopic mounting rods.

[0013] As a preferred technical solution of this utility model, a slot is provided on the inner side of the horizontal plate, and a top plate is engaged and installed inside the slot.

[0014] As a preferred technical solution of this utility model, bolt holes are equally spaced on both sides of the slide groove on the surface of the base, and a telescopic rod is fixedly connected to the outside of the column mold by rotating the bolt on the base.

[0015] This utility model has the following beneficial effects: 1. By setting an inner mold assembly on the sliding component, the relative overlap distance between the two can be changed by pushing the first arc plate to slide in the inner groove of the second arc plate. The arc contour between the inner mold plate and the horizontal plate can be quickly adjusted to perfectly match the design curvature of the inner wall of the box culvert to be formed. The sliding is stopped and the relative position of the first arc plate and the second arc plate is temporarily fixed. Then, the first arc plate and the second arc plate are fixed together with bolts. This can meet the different needs of personnel for the curvature of the box culvert, thereby further improving the applicability of the device.

[0021] The following is based on Figure 1 - Figure 5 This invention describes the concrete box culvert forming mold provided in an embodiment of the present invention.

[0022] Please see Figure 1 - Figure 5The present invention provides a technical solution: a concrete box culvert forming mold, including a base 1 and a sliding component 2 installed on the surface of the base 1, and also including an outer mold component 5, the outer mold component 5 being symmetrically installed on the sliding component 2, and an inner mold component 8 being provided on the inner side of the outer mold component 5 on the sliding component 2. Support component 9 is located inside the inner mold assembly 8. The inner mold assembly 8 and support component 9 form a triangular structure to support the inner curvature of the inner mold assembly 8, thereby further improving the stability and applicability of the device. The inner mold assembly 8 includes an inner mold plate 801 installed on the inner sliding block 203. An arc plate 1 802 is installed on the top of the inner mold plate 801. An arc plate 2 803 is slidably installed on the outer side of the arc plate 1 802. A horizontal plate 804 is fixedly installed on one side of the arc plate 2 803. Support component 9 includes telescopic mounting rods 901 symmetrically installed inside the inner mold plate 801. A fixing plate 902 is fixedly installed inside the horizontal plate 804. Fixing grooves 903 are evenly spaced on the fixing plate 902. The telescopic mounting rods 901 are inserted into the fixing grooves 903, forming a triangular structure with the telescopic mounting rods 901. A slot 10 is opened inside the horizontal plate 804. A top plate 11 is engaged inside the slot 10. In this embodiment, after the outer mold assembly 5 is installed onto the outer sliding block 203, the two sets of inner mold plates 801 are then fixed onto the two sets of inner sliding blocks 203 respectively. At this time, the curvature of the arc plate 1 802 and arc plate 2 803 between the inner mold plate 801 and the horizontal plate 804 can be adjusted according to the curvature inside the box culvert. Since the bottom of arc plate 1 802 is fixedly connected to the top of the inner mold plate 801, and one side of arc plate 2 803 is fixedly connected to the horizontal plate 804, the relative curvature of the two can be changed by pushing arc plate 1 802 to slide in the inner cavity of arc plate 2 803. The overlap distance is adjusted as follows: when arc-shaped plate 802 slides towards one end of arc-shaped plate 803, the overlap area increases, and the curvature of the arc-shaped connecting section between the inner mold plate 801 and the horizontal plate 804 decreases. When arc-shaped plate 802 slides towards the other end of arc-shaped plate 803, the overlap area decreases, and the curvature of the arc-shaped connecting section between the inner mold plate 801 and the horizontal plate 804 increases. This adjustment continues until the arc-shaped contour between the inner mold plate 801 and the horizontal plate 804 perfectly matches the designed curvature of the inner wall of the box culvert to be formed. At this point, the sliding stops, and the relative positions of arc-shaped plate 802 and arc-shaped plate 803 are temporarily fixed. Then, the arc-shaped plate 802 and the arc-shaped plate 803 are fixed together with bolts to meet the different requirements of personnel for the curvature of the box culvert, thereby further improving the applicability of the device. At the same time, the length of the telescopic mounting rod 901 on the inner side of the inner mold plate 801 in the support assembly 9 is adjusted, and the free end of the telescopic mounting rod 901 is inserted into the corresponding fixing groove 903 on the fixing plate 902 on the inner side of the horizontal plate 804. At this time, the inner mold plate 801, the telescopic mounting rod 901, and the fixing plate 902 form a triangular structure. This structure can directly support the inner mold plate 801, the arc-shaped plate 802, and the arc-shaped plate 803. The shaped arc formed by 803 and the horizontal plate 804 provides rigid support, offsetting the lateral pressure during subsequent concrete pouring, preventing the arc plate assembly from shifting due to stress, ensuring the accuracy of the arc of the inner wall of the box culvert, and improving the quality of the equipment in processing the concrete box culvert. At the same time, the top plate 11 is aligned with the slot 10 on the inner side of the horizontal plate 804 and inserted into the top plate 11 along the slot 10, so that the top plate 11, together with the two sets of horizontal plates 804 and the two sets of inner mold plates 801, constitutes the inner mold closed structure. At this time, the arc section of the pouring cavity between the outer mold assembly 5 and the inner mold assembly 8 fully conforms to the modified and adjusted inner wall design dimensions of the box culvert.

[0023] Specifically, the sliding component 2 includes a groove 201 formed on the surface of the base 1, a sliding rod 202 fixedly installed in the groove 201, four sets of sliding blocks 203 slidably installed on the sliding rod 202, an outer mold assembly 5 installed on the two outer sets of sliding blocks 203, and an inner mold assembly 8 installed on the two inner sets of sliding blocks 203. The outer mold assembly includes a column mold 501 installed on the sliding block 203, a corresponding groove 502 is formed at one end of the top of the column mold 501, a horizontal plate mold 503 is installed inside the corresponding groove 502, and bolt holes 3 are equally spaced on both sides of the groove 201 on the surface of the base 1. A telescopic rod 4 is rotatably installed on the base 1 and fixedly connected to the outer side of the column mold 501 by bolts. In this embodiment, two sets of outer sliding blocks 203 are fitted onto the slide rod 202 within the slide groove 201. The outer sliding blocks 203 slide axially along the slide rod 202, causing the column molds 501 mounted on the sliding blocks 203 to move synchronously until the distance between the two sets of column molds 501 matches the outer width of the box culvert. The slide rod 202 acts as a guide, ensuring the column molds 501 remain parallel during movement and preventing deviation. Simultaneously, the two sets of inner sliding blocks 203 also slide along the slide rod 202, causing the inner mold plates 801 on them to move, matching the distance between the two sets of inner mold plates 801 with the inner width of the box culvert. Through the sliding fit between the top arc plate 802 and the second arc plate 803 of the inner mold plate 801, the curvature of the inner wall of the inner mold is adjusted to meet the curvature design requirements of the inner wall of the box culvert. Then, the sliding block 203 is fixed to the bolt hole 3 by bolts, so that the outer mold assembly 5 and the inner mold assembly 8 are connected as a whole. Then, the extension length of the telescopic rod 4 is adjusted so that the free end of the telescopic rod 4 is tightly attached to and fixed to the outer wall of the column mold 501. The supporting force of the telescopic rod 4 offsets the lateral pressure on the column mold 501 during subsequent concrete pouring, further improving the overall stability of the outer mold assembly 5 and facilitating the pouring and processing of the concrete box culvert by personnel.

[0024] Specifically, the horizontal plate mold 503 has fixing holes 6 at equal intervals, and a fixing component 7 is provided on the corresponding groove 502 at the position corresponding to the fixing holes 6. The fixing component 7 includes a placement groove 701 opened on one side of the corresponding groove 502, a fixing rod 702 installed in the placement groove 701, and a spring 703 fitted on the fixing rod 702 in the placement groove 701.

[0025] In this embodiment, the horizontal plate mold 503 is aligned with the corresponding groove 502 on the top of the column mold 501, and inserted into the horizontal plate mold 503 along the corresponding groove 502 until both ends of the horizontal plate mold 503 are inserted into the corresponding grooves 502 of the two sets of column molds 501. At this time, the horizontal plate mold 503 and the two sets of column molds 501 together form the rectangular frame of the outer mold. When the horizontal plate mold 503 is inserted into the corresponding groove 502, the horizontal plate mold 503 will push the fixing rod 702 to move axially along the placement groove 701. When the fixing rod 702 corresponds to the fixing hole 6, the continuous elastic force of the spring 703 keeps the fixing rod 702 engaged with the fixing hole 6, preventing the horizontal plate mold 503 from loosening or shifting during casting. If disassembly is required, simply pull the fixing rod 702 upward to disengage the fixing rod 702 from the fixing hole 6, and the horizontal plate mold 503 can be separated from the two sets of column molds 501.

[0026] The working principle and usage process of this utility model are as follows: According to the dimensions of the box culvert, the spacing between the inner and outer molds is planned. The sliding block 203 of the sliding component 2 slides along the sliding rod 202. The outer sliding block 203 drives the column mold 501 to adjust to the outer width of the box culvert, and the inner sliding block 203 drives the inner mold plate 801 to adjust to the inner width. In the outer mold, the horizontal plate mold 503 is inserted into the corresponding groove 502 on the inner side of the column mold 501. The fixing rod 702 of the fixing component 7 is locked into the fixing hole 6. The telescopic rod 4 assists in supporting the column mold 501. In the inner mold, the arc plate one 802 slides in the arc plate two 803 to adjust to the required arc. The telescopic installation rod 901 is inserted into the fixing groove 903 to form a triangular support. The top plate 11 is inserted into the slot 10 to close the inner mold. A pouring cavity is formed between the inner and outer molds. Concrete is injected into the pouring cavity and vibrated. It is cured to the standard strength. First, the outer mold component 5 is removed, then the inner mold component 8 is removed. Finally, the sliding block 203 is reset and the mold is cleaned for later use.
