Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically discloses a reusable distribution box niche mold. Background Technology

[0002] On construction sites, for non-standardized, low-turnover, or extremely limited-budget concrete molding needs, it is common to make molds by combining wooden formwork with square timber. This method takes advantage of the fact that wood is easy to process and has a low cost. First, the wooden formwork is cut according to the size of the niche, and then square timber is used as a keel for reinforcement and assembly to complete the construction. It has a certain degree of flexibility and economy.

[0003] However, the existing method of combining wooden formwork with square timber has drawbacks. Due to the low strength of the wooden formwork material, it is prone to damage and deformation after a few uses, requiring frequent replacement of the formwork, resulting in a large amount of material waste and increased construction costs. Furthermore, the existing molds are prone to deviations in the installation angle of components, and manual adjustment of the angle makes it difficult to ensure the installation accuracy of the distribution box. Moreover, the wooden formwork is prone to decay and cracking in various outdoor environments such as humidity or sun exposure, reducing the service life of the formwork, and special protection is required for its storage. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a reusable distribution box niche mold to solve the problems of wooden templates being easily damaged and deformed, having deviations in component angles, and being unable to adapt to outdoor environments such as dampness or sun exposure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The reusable distribution box niche mold includes four sets of steel templates. The four sets of steel templates are rectangular in shape. Adjacent sets of steel templates are connected by a connecting mechanism. Each of the four connecting mechanisms and the corresponding steel templates is equipped with a fine-adjustment mechanism. A base plate is fixedly installed at the bottom of the four sets of steel templates, and a PVC rigid plastic sleeve is fixedly installed at the middle of the top of the base plate.

[0007] The fine-tuning mechanism includes a fixed sleeve fixedly installed in the middle of one side of the steel template. A threaded rod is threaded through the fixed sleeve and threaded through it. An adjusting component is rotatably installed at one end of the threaded rod. The adjusting component has a conical structure and is slidably installed between the corresponding steel template and the connecting mechanism.

[0008] Furthermore, the connecting mechanism includes an angle iron disposed between two adjacent sets of steel templates, with several pins running through the angle iron, and the angle iron is fixedly connected to the two adjacent sets of steel templates by the pins.

[0009] Furthermore, the bottom surface of the adjusting component is rotatably connected to the threaded rod, and the diameter of the bottom surface of the adjusting component is greater than the distance between the corresponding steel template and the connecting mechanism.

[0010] Furthermore, sliding parts are fixedly installed on both sides of the adjusting part, and sliding grooves are opened on the opposite sides of the corresponding steel template and angle iron to cooperate with the adjusting part and the two sets of sliding parts. The two sides of the adjusting part are slidably installed in the two sets of sliding grooves, and the two sets of sliding parts are slidably installed in the two sets of sliding grooves.

[0011] Furthermore, the width of the side of the slider away from the adjusting member is greater than the width of the sliding groove opening, so that the slider can be engaged in the sliding groove.

[0012] Furthermore, the inner wall of the fixed sleeve is provided with an internal thread, and the fixed sleeve is threadedly connected to the threaded rod through the internal thread. A rotating part is fixedly provided at the end of the threaded rod away from the adjusting part.

[0013] Furthermore, the top and bottom ends of the steel formwork are each provided with a number of through holes that are evenly spaced and intermittently opened. Several fixing bolts are threaded into the through holes at the bottom end of the steel formwork, and the steel formwork and the base plate are fixedly connected by the fixing bolts.

[0014] Furthermore, several PVC sleeves are evenly and intermittently arranged on both sides of the PVC rigid plastic mold and between the corresponding two sets of steel templates, and all the PVC sleeves are arranged horizontally.

[0015] Furthermore, the end of the PVC sleeve closest to the rigid PVC mold is tightly fitted to the outer wall of the rigid PVC mold, while the end of the PVC sleeve furthest from the rigid PVC mold is tightly fitted to the side of the steel template closest to the rigid PVC mold.

[0016] Furthermore, several reinforcing rods are evenly and spacedly fixed between the inner walls of both sides of the steel formwork, and all the reinforcing rods are horizontally arranged.

[0017] The beneficial effects of this utility model are:

[0018] This invention uses a connecting mechanism to fix adjacent sets of steel formwork, a simple and reliable connection method that makes the assembly and disassembly of the formwork faster, saving construction time and labor costs. A fine-tuning mechanism allows for adjustments when the steel formwork assembly angle deviates slightly, avoiding errors caused by manual angle adjustments and ensuring accuracy in every assembly. Using steel formwork as the main material, this invention leverages the superior strength and durability of steel compared to wood, along with its excellent rigidity. Steel is not easily deformed during concrete pouring and can withstand the pressure and wear of multiple concrete pours, significantly increasing the number of reusable units, reducing the frequency of formwork replacement, lowering costs, and enabling precise control of the cross-sectional dimensions of the electrical box niche, ensuring dimensional accuracy and appearance quality of the components. The steel formwork is corrosion-resistant and highly resistant to deformation, not easily damaged in humid or sun-exposed outdoor environments, and requires no special protective measures during storage, facilitating storage and management and extending the formwork's service life.

[0025] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1-5As shown, the reusable distribution box niche mold includes four sets of steel templates 1. The four sets of steel templates 1 are rectangular in shape. Adjacent sets of steel templates 1 are connected by a connecting mechanism 2. A fine-tuning mechanism 3 is provided between the four connecting mechanisms 2 and the corresponding steel templates 1. A base plate 4 is fixedly provided at the bottom of the four sets of steel templates 1. A PVC rigid plastic sleeve mold 5 is fixedly provided at the middle of the top of the base plate 4.

[0028] The fine-tuning mechanism 3 includes a fixed sleeve 31 fixedly installed in the middle of one side of the steel template 1. A threaded rod 32 is threaded through the fixed sleeve 31. An adjusting member 33 is rotatably installed at one end of the threaded rod 32. The adjusting member 33 has a conical structure and is slidably installed between the corresponding steel template 1 and the connecting mechanism 2.

[0029] With the above setup, the four sets of steel formwork 1 are connected into a frame structure of the mold via the connecting mechanism 2; the surface of the base plate 4 is smooth, which can reduce the friction between the concrete and the formwork, facilitating demolding; after the angles of the four sets of steel formwork 1 are adjusted and fine-tuned by the fine-tuning mechanism 3, the base plate 4 is fixedly connected to the bottom of the four sets of steel formwork 1; the PVC rigid plastic sleeve mold 5 is installed according to the outer dimensions and thickness of the on-site distribution box; the connecting mechanism 2 is used to fix adjacent sets of steel formwork 1, and the connection method is simple and reliable, making the assembly and disassembly of the steel formwork 1 faster and saving construction time and labor costs; the fine-tuning mechanism 3 can be used to fine-tune the steel formwork 1 when there is a slight deviation in the assembly, avoiding the error caused by manually adjusting the angle of the steel formwork 1, and ensuring the accuracy of each assembly.

[0030] The connecting mechanism 2 includes an angle iron 21 disposed between two adjacent sets of steel templates 1. Several pins 22 are disposed through the angle iron 21, and the angle iron 21 is fixedly connected to the two adjacent sets of steel templates 1 by the pins 22.

[0031] The bottom surface of the adjusting component 33 is rotatably connected to the threaded rod 32, and the diameter of the bottom surface of the adjusting component 33 is greater than the distance between the corresponding steel template 1 and the connecting mechanism 2.

[0032] Both sides of the adjusting member 33 are fixedly provided with sliding members 35. The corresponding steel template 1 and angle iron 21 are provided with sliding grooves on opposite sides to cooperate with the adjusting member 33 and sliding members 35. The two sides of the adjusting member 33 are respectively slidably arranged in two sets of sliding grooves, and the two sets of sliding members 35 are respectively slidably arranged in two sets of sliding grooves.

[0033] The width of the side of the slider 35 away from the adjusting member 33 is greater than the width of the sliding groove opening, so that the slider 35 can be engaged in the sliding groove.

[0034] With the above configuration, the sliding groove on the angle iron 21 penetrates the side wall of the angle iron 21. When the steel template 1 and the connecting mechanism 2 are connected, the sliding member 35 and the adjusting member 33 are first inserted into the sliding groove on the angle iron 21, and then fine-tuning is performed. After the fine-tuning is completed, the angle iron 21 and the corresponding steel template 1 are fixedly connected by passing several pins 22 through the angle iron 21 and the corresponding steel template 1.

[0035] The inner wall of the fixed sleeve 31 is provided with an internal thread. The fixed sleeve 31 is threadedly connected to the threaded rod 32 through the internal thread. The end of the threaded rod 32 away from the adjusting member 33 is fixedly provided with a rotating member 34.

[0036] With the above settings, when there is a slight deviation in the assembly of the steel template 1, causing the angle between two adjacent sets of steel template 1 to be greater than 90°, the angle iron 21 and the side of the steel template 1 closest to the angle iron 21 away from the fine-tuning mechanism 3 are fixed. Then, the rotating part 34 is turned to drive the threaded rod 32 to rotate within the fixed sleeve 31, causing the threaded rod 32 to move. The movement of the threaded rod 32 drives the adjusting part 33 to move. At this time, the two sets of sliding parts 35 slide in the two sets of sliding grooves respectively, and the adjusting part 33 also slides along the two sets of sliding grooves, causing the steel template 1 to move closer to the angle iron 21. The distance between the side of angle iron 21 closest to the fine-tuning mechanism 3 and the side of angle iron 21 closest to the fine-tuning mechanism 3 increases, thereby causing the steel template 1 to rotate and reducing the included angle between the two sets of steel templates 1. When the included angle between the two sets of steel templates 1 is 90°, the rotation of the rotating part 34 is stopped. When the angle between two adjacent sets of steel templates 1 is less than 90°, the angle iron 21 and the side of the steel template 1 closest to the angle iron 21 away from the fine-tuning mechanism 3 are fixed, and then the rotating part 34 is rotated in the opposite direction to make the included angle between the two adjacent sets of steel templates 1 90°.

[0037] The top and bottom ends of the steel formwork 1 are provided with several through holes 6 evenly spaced and intermittently. Several fixing bolts are threaded inside the several through holes 6 at the bottom end of the steel formwork 1. The steel formwork 1 and the base plate 4 are fixedly connected by several fixing bolts.

[0038] Several PVC sleeves 7 are evenly and intermittently arranged on both sides of the PVC rigid plastic mold 5 and between the corresponding two sets of steel templates 1, and the several PVC sleeves 7 are all horizontally arranged.

[0039] The end of the PVC sleeve 7 closest to the PVC rigid plastic mold 5 is tightly fitted to the outer wall of the PVC rigid plastic mold 5, and the end of the PVC sleeve 7 furthest from the PVC rigid plastic mold 5 is tightly fitted to the side of the steel template 1 closest to the PVC rigid plastic mold 5.

[0040] With the above setup, several PVC sleeves 7 are pre-embedded according to the pipeline positions of the distribution box on the drawings; after demolding, several PVC sleeves 7 are left inside the mold structure.

[0041] Several reinforcing rods 8 are evenly and spacedly fixed between the inner walls of both sides of the steel formwork 1, and all reinforcing rods 8 are horizontally arranged. The reinforcing rods 8 are used to improve the stability of the steel formwork 1 structure and ensure the stability of the concrete pouring process.

[0042] Working principle and process:

[0043] Before construction, determine the specifications and dimensions of the steel formwork 1 and the PVC rigid plastic sleeve 5 based on the outer dimensions and thickness of the distribution box. Then, assemble the molds by connecting the four sets of steel formwork 1 through four sets of connecting mechanisms 2, ensuring that the included angle between adjacent sets of steel formwork 1 is 90°. Then, place the base plate 4 at the bottom of the four sets of steel formwork 1. At this point, check the included angle between adjacent sets of steel formwork 1. If the included angle is greater than 90°, fix the angle iron 21 and the side of the steel formwork 1 closest to the angle iron 21 away from the fine-tuning mechanism 3. Then, rotate the rotating part 34 to drive the threaded rod 32 to rotate within the fixed sleeve 31, causing the threaded rod 32 to move away from the rotating part 34. The movement of the threaded rod 32 drives the adjustment component 33 to move. At this time, the two sets of sliding components 35 slide in the two sets of sliding grooves respectively, and the adjustment component 33 also slides along the two sets of sliding grooves, so that the distance between the side of the steel template 1 near the angle iron 21 and the side of the angle iron 21 near the fine adjustment mechanism 3 increases, thereby causing the steel template 1 to rotate and reduce the included angle between the two sets of steel template 1. When the included angle between the two sets of steel template 1 is 90°, stop turning the rotating component 34; if the included angle is less than 90°, fix the angle iron 21 and the side of the steel template 1 near the angle iron 21 away from the fine adjustment mechanism 3, and then turn the rotating component 34 in the opposite direction so that the included angle between the two adjacent sets of steel template 1 is 90°.

[0044] After adjusting the included angle of the four sets of steel templates 1, fix the angle iron 21 and the corresponding steel template 1 by passing several pins 22 through the angle iron 21 and the corresponding steel template 1; then fix the base plate 4 and the four sets of steel templates 1 by passing several through holes 6 through the bottom of the base plate 4 and the four sets of steel templates 1; then fix the base plate 4 and the four sets of steel templates 1 by passing several fixing bolts through the bottom holes 6 through the bottom holes 6; then fix the PVC rigid plastic sleeve 5 in the middle of the top of the base plate 4 to ensure that the four sets of steel templates 1, the base plate 4 and the PVC rigid plastic sleeve 5 are installed firmly and in accurate position; then pour concrete into the assembled mold, vibrate and compact it, and then cure it; after the concrete reaches the demolding strength, first remove the PVC rigid plastic sleeve 5, then remove the base plate 4, the steel template 1 and the connecting mechanism 2 in sequence to complete the demolding; after demolding, several PVC sleeves 7 are left inside the mold structure; after the demolding is cleaned, the mold can be reused or stored.
