Description

Technical Field

[0001] This utility model relates to the field of prefabrication mold technology, specifically to a prefabrication block mold for a post-construction wall distribution box. Background Technology

[0002] Post-construction walls, a common secondary structure construction technique in modern architecture, refer to non-load-bearing walls that are built after the main frame structure is completed. They are usually constructed using materials such as aerated concrete blocks and lightweight partition boards. In building electrical engineering, distribution boxes are important nodes for power distribution. When installing distribution boxes on post-construction walls, it is often necessary to reserve an opening for the distribution box to be installed in the later wall.

[0003] Traditional construction methods typically involve on-site cutting and grooving or pre-drilling holes, which can lead to low construction efficiency, poor positioning accuracy, and damage to masonry structures. Furthermore, manually drilled holes can have large size deviations, which can easily cause quality issues such as hollow areas and cracks around the distribution box after installation.

A release template is detachably connected to the perimeter of the stop block. The bottom surface of the stop block is spaced apart from the upper surface of the base plate.

[0008] The stop block is located in the middle of the rectangular frame to form a precast concrete chamber for the distribution box between the rectangular frame and the stop block.

[0009] Optionally, the fixing mechanism includes a fixing plate, threaded rods, and a push plate. The fixing plate is fixedly connected to the upper surface of the base plate. There are four threaded rods, which are respectively threaded to the middle of the fixing plate and the support frame. The push plate is rotatably disposed at one end of the threaded rods and fits against the outer surface of the enclosure.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a precast block mold for a post-construction wall distribution box, including a base plate 1 and a surrounding plate 2. The surrounding plate 2 is provided on the upper surface of the base plate 1 and there are four of them. The four surrounding plates 2 and the base plate 1 together form a rectangular frame with an opening at the top.

[0024] The upper surface of the base plate 1 is provided with a fixing mechanism to fix the position of the enclosure 2;

[0025] A support frame 3 is fixedly connected to the upper surface of the base plate 1. An adjusting rod 4 is threadedly connected to the top of the support frame 3. A connecting seat 5 is rotatably connected to the bottom of the adjusting rod 4. A stop block 6 is connected to the lower surface of the connecting seat 5 through a snap-fit ​​mechanism. A stripping template 7 is detachably connected around the stop block 6. The bottom surface of the stop block 6 is spaced apart from the upper surface of the base plate 1.

[0026] The stop block 6 is located in the middle of the rectangular frame to form a precast concrete chamber for the distribution box between the rectangular frame and the stop block 6.

[0027] The base plate 1 is placed on the ground, and the base plate 1 and four surrounding plates 2 form a rectangle. The position of the surrounding plates 2 can be adjusted by adjusting the fixing mechanism, thereby adjusting the size of the rectangle enclosed by the surrounding plates 2. During pouring, it can be adjusted according to the size of the bricks used for the post-construction wall. The pouring operation can be carried out in the factory, shortening the time required for the post-construction wall. The adjusting rod 4 adjusts the height of the stop block 6. The stop block 6 is located in the middle of the surrounding plate 2. During pouring, the position covered by the stop block 6 can form a cavity, thereby installing the distribution box. The stop block 6 is detachably set at the bottom of the adjusting rod 4 and can be replaced for different needs to pour cavities of different sizes for installing the distribution box. The demolding formwork 7 is detachably set around the stop block 6. During demolding, the stop block 6 can be pulled out first, and then the demolding formwork 7 can be removed from the poured post-construction wall bricks for easy demolding. The horizontal bar at the top of the support frame 3 is fixed to the vertical bar with bolts. When the pouring size is large, the horizontal bar can be removed to prevent the horizontal bar from blocking the pouring block from being removed.

[0028] In this embodiment, as a preferred solution, the fixing mechanism includes a fixing plate 8, threaded rods 9, and a push plate 10. The fixing plate 8 is fixedly connected to the upper surface of the base plate 1. There are four threaded rods 9, which are respectively threadedly connected to the middle of the fixing plate 8 and the support frame 3. The push plate 10 is rotatably disposed at one end of the threaded rods 9 and fits against the outer surface of the enclosure 2. One end of the enclosure 2 is detachably connected to a connecting plate 11 for connecting adjacent enclosures 2. The upper surface of the base plate 1 is provided with multiple scales 12 for adjusting the position of the enclosure 2.

[0029] The push plate 10 rests against the outside of the enclosure plate 2. The threaded rod 9 can be rotated to adjust the extension length of the threaded rod 9 from the fixed plate 8, thereby adjusting the size of the frame enclosed by the four enclosure plates 2. The connecting plate 11 is triangular and fixes two adjacent enclosure plates 2 together, preventing the enclosure plates 2 from tilting during the pouring process. The relative position of the four enclosure plates 2 can be adjusted by the scale 12, making it easier to adjust the stop block 6 to the center position, resulting in more accurate dimensions during pouring.

[0030] In this embodiment, as a preferred solution, the snap-fit ​​mechanism includes an arc-shaped groove 13 and a connecting buckle 14. The arc-shaped groove 13 is formed on the upper surface of the stop block 6, and the connecting buckle 14 is fixedly connected to the lower surface of the connecting seat 5. The connecting buckle 14 and the arc-shaped groove 13 snap-fit ​​together to fix the connecting seat 5 and the stop block 6.

[0031] A large opening is provided on one side of the arc-shaped groove 13, allowing the connecting buckle 14 to be inserted into the arc-shaped groove 13 from the side with the larger opening. By rotating, the connecting buckle 14 can be rotated into the arc-shaped groove 13, so that the connecting buckle 14 and the arc-shaped groove 13 are limited in the vertical direction, thereby fixing the connecting buckle 14 in the arc-shaped groove 13. During use, the stop block 6 can be quickly disassembled and installed, and the size of the stop block 6 can be flexibly adjusted during use. The connecting seat 5 can be rotated to easily adjust the stop block 6 to a horizontal and vertical position.

[0032] In this embodiment, as a preferred option, the bottom of the stop block 6 is provided with a positioning groove 15, and the bottom of the stripping template 7 near the stop block 6 is provided with a positioning block 16 that matches the positioning groove 15. The positioning block 16 is engaged with the positioning groove 15 to fix the stripping template 7 to the outer wall of the stop block 6. A lever 17 is rotatably connected to the upper surface of the stripping template 7, and one side of the lever 17 is attached to the upper surface of the stop block 6 to fix the stripping template 7.

[0033] The positioning block 16 on the stripping template 7 can be locked in the positioning groove 15 from bottom to top, thereby splicing the stripping template 7 and the stop block 6 together. When the lever 17 is rotated, the lever 17 can rotate above the stop block 6, thereby preventing the stripping template 7 from falling and fixing the stripping template 7 stably on the stop block 6.

[0034] In this invention, the working steps of the device are as follows:

[0035] 1. Rotate the four external threaded rods 9 to adjust the enclosure 2 to the required size for pouring and fix the position of the enclosure 2 with the connecting plate 11. Select the corresponding size of the stop block 6, fix the demolding template 7 around the stop block 6 and fix it with the pry bar 17. After fixing it, fix the stop block 6 to the bottom of the adjusting rod 4. Rotate the adjusting rod 4 to insert the stop block 6 into the cavity in the middle of the enclosure 2. Adjust the moving distance of the stop block 6 to the depth consistent with the size of the distribution box.

[0036] 2. After the position is adjusted, pour concrete into the cavity inside the enclosure 2. After the concrete has solidified, remove the connecting plate 11 and loosen the threaded rod 9. Remove the enclosure 2 around the perimeter and pry open the pry bar 17 at the top of the formwork 7. After the formwork 7 is separated from the stop block 6, rotate the adjusting rod 4 to raise the stop block 6. If the size is large, disassemble the support frame 3 and then remove the stop block 6.

[0037] 3. After removing the stop block 6, remove the formwork 7 in the cavity one by one, and then take out the poured concrete block.

[0038] 4. During construction, masonry is carried out directly. When the masonry reaches the lower edge of the distribution box, the poured concrete block is installed on the back wall. The poured cavity is adjusted to face outwards to install the distribution box. Then masonry is continued until the back wall is completed.
