Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a mold for making the plastering around the pre-embedded bottom box in the wall neat and orderly. Background Technology

[0002] In electrical and plumbing installation projects, the conventional construction sequence for switch and socket junction boxes falls into two categories. The first is in concrete structures, where PVC boxes are first fixed to the reinforcing steel structure. Foam boards are then filled inside the PVC boxes, and the outer opening of the PVC box is tightly fixed to the formwork. After the concrete is poured and the formwork is removed, the outer opening of the PVC box protrudes from the concrete surface. Later, after plastering, the PVC box will be recessed into the plaster layer. The second is after the masonry work is completed, where grooves need to be cut into the masonry to fix the PVC boxes. Due to time constraints or other reasons, the height of the PVC box protruding from the wall is difficult to determine when the plaster layer thickness is uncertain. The common practice is to minimize the protrusion to avoid the PVC box sticking out of the plaster layer later. However, this also results in the PVC box being recessed into the plaster layer after plastering.

[0003] If the PVC boxes for switches and sockets are embedded in the plaster layer, or if the plaster finish around the PVC boxes is irregular or there is no finish even when the wall is plastered over a large area, it will be difficult to repair the area around the PVC boxes with putty or other materials during the finishing stage. Alternatively, the PVC cover plate may not be able to completely cover the gaps around the boxes when it is installed, resulting in secondary repairs or quality defects. Utility Model Content

[0004] The purpose of this utility model is to provide a mold that makes the plastering around the PVC box embedded in the wall neat and orderly. By setting up a frustum, extension plate, screw rod and nut, it solves the problems of the PVC box of the switch and socket sinking into the plaster layer, the irregular shape of the plastering end around the PVC box when the wall is plastered over a large area, or the lack of plastering end at a distance from the PVC box. This will make it difficult to repair the PVC box with putty or other materials during the fine decoration stage, or the cover plate cannot completely cover the gap around the box when installing the PVC cover plate, resulting in secondary repairs or quality defects.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mold for making the plastering around the pre-embedded bottom box in the wall neat, comprising two truncated pyramids, a slot is provided between the two truncated pyramids, an extension plate is engaged inside the slot, a threaded rod is welded to one side of the inner wall of the truncated pyramids, a nut is threaded onto the surface of the threaded rod, and a sleeve is welded to one side of the nut.

[0006] Preferably, the two ends of the extension plate are fixedly connected with locking blocks, and the corners of the inner wall of the frustum are welded with reinforcing blocks.

[0007] Preferably, a groove is provided at the bottom of one side of the frustum, and a screw sleeve is welded to the inner wall of the frustum above the groove.

[0008] Preferably, a fastening screw is inserted into the inside of the screw socket, and a locking nut is threaded onto the surface of the fastening screw.

[0009] Preferably, a handle is welded to the surface of the sleeve.

[0010] This utility model provides a mold for neatly plastering around the pre-embedded base box in a wall, which has the following features:

[0011] Beneficial effects:

[0012] In use, this equipment is inserted into the PVC base box during the plastering stage, allowing the plastering mortar to adhere firmly to the perimeter of the PVC base box. The mortar at the perimeter of the PVC base box is square and the same size as the PVC base box. When used with double base boxes, the drive frustum can be moved to both sides by rotating the sleeve, so that the frustum on both sides abuts against the two ends of the double base box. The plastering mortar is blocked in the middle by the extension plate. After the mortar sets, the mold is removed and can be reused. This equipment ensures that the plastering perimeter of the PVC base box is neat and tidy, which facilitates the installation of subsequent cover plates and other components, and reduces the time spent on subsequent repairs.

[0021] 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.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a mold for making the plastering around the pre-embedded bottom box in the wall neat and orderly. It includes two frustums 1. The two frustums 1 can be directly inserted into the PVC bottom box after being combined. The top size of the two frustums 1 after being combined is 75mm*75mm, the bottom size is 65mm*65mm, and the height is 70mm. A slot 2 is opened between the two frustums 1. An extension plate 3 is engaged inside the slot 2. A threaded rod 4 is welded to one side of the inner wall of the frustum 1. A nut 5 is threaded on the surface of the threaded rod 4. A sleeve 6 is welded to one side of the nut 5. The inner diameters of the two nuts 5 are the same, and the helical directions of the threads in the two nuts 5 are opposite. When the sleeve 6 rotates, it drives the two threaded rods 4 to rotate outward, thereby achieving the effect of pushing the frustums 1 to both ends, achieving the effect of using a double bottom box.

[0023] The two ends of the extension plate 3 are fixedly connected with the locking blocks 7, and the corner of the inner wall of the frustum 1 is welded with the reinforcing block 8. The extension plate 3 can block the middle part when the two frustums 1 are extended, thereby preventing mortar from entering. The locking blocks 7 can prevent the extension plate 3 from falling out and causing mortar to enter. Under the action of the reinforcing block 8, excessive force is prevented when the equipment is inserted into the bottom box, which may cause deformation at the corner of the frustum 1.

[0024] A groove 9 is provided at the bottom of one side of the frustum 1. A screw sleeve 10 is welded to the inner wall of the frustum 1 above the groove 9. A fastening screw 11 is inserted into the screw sleeve 10. A locking nut 12 is threaded onto the surface of the fastening screw 11. In use, the fastening screw 11 is inserted into the screw sleeve 10 and the locking nut 12 is screwed in. Then the fastening screw 11 is screwed into the base box, thereby fixing the frustum 1 in the base box and preventing the equipment from falling off when the mortar is smoothed.

[0025] A handle 13 is welded to the surface of the sleeve 6.

[0026] Specifically, this mold for neatly plastering around the pre-embedded wall base box works as follows: During use, the equipment is inserted into the PVC base box during the plastering stage, allowing the plastering mortar to adhere firmly to the perimeter of the PVC base box. The mortar around the perimeter of the PVC base box is square and the same size as the PVC base box. When used for double base boxes, the sleeve 6 can be rotated to move the driving frustum 1 to both sides, so that the frustum 1 on both sides abuts against the two ends of the double base box. The extension plate 3 blocks the plastering mortar in the middle. After the mortar sets, the mold is removed and can be reused. This equipment makes the plastering around the PVC base box neat and tidy, which facilitates the installation of subsequent cover plates and other components, and reduces the time spent on subsequent repairs.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
