Abstract
Description
Technical Field
[0001] This application relates to the field of building application technology, and in particular to a one-time forming device for multi-level drop sills and inverted sills in multi-water rooms and its construction method. Background Technology
[0002] During the construction process, the floors are equipped with lowered slabs or multiple lowered slabs in areas with high water content, such as toilets and bathrooms. In addition, 200mm high plain concrete water-stopping curbs are set around the perimeter. The conventional practice is to use a suspended formwork process for one-time molding or a secondary pouring process after the main structure is completed.
[0003] In existing technologies, the formwork used for one-time molding lacks fixed points within the area, and the small height difference of the lowered slab makes it impossible to install tie rods for reinforcement. After molding, the deviation of the lowered slab and the water-stop curb is large, failing to meet quality requirements and necessitating secondary repairs, which increases labor and time costs significantly. However, after the main structure is completed, a secondary formwork and pouring process is required, which poses a significant risk of leakage at the floor slab and water-stop curb. Furthermore, the labor cost of secondary construction is far higher than that of the primary pouring. Therefore, improvements are needed. Summary of the Invention

[0010] In one embodiment, a PVC sleeve that can separate the floor slab support surface is provided on the positioning screw.
[0011] In one embodiment, the limiting component includes: a limiter, a limiting screw, and a plurality of second adjusting nuts corresponding to and adapted to the limiting screw; the limiting screw is disposed on the transverse square tube; one end of the limiter is connected to the vertical square tube, and the other end of the limiter is connected to the limiting screw; the plurality of second adjusting nuts are all movably disposed on the limiting screw.
[0012] In one embodiment, a second reinforcing timber is provided on the limiter; a limiting wooden template is provided on the second reinforcing timber; the limiting wooden template connects to the multi-level drop area of the floor slab.
[0013] In one embodiment, the limiting screw is adapted to the length of the vertical square tube.

[0018] At the proposed construction site of the water-filled room, a multi-stage lowering formwork system is assembled using limiting wooden formwork and second reinforcing wooden blocks. Limiting screws are installed and pass through the multi-stage lowering formwork system. The lowering and positioning of the formwork system is achieved by tightening the second adjusting nut to ensure the accurate horizontal position of the device.
[0019] By welding the limiter to the support frame, and connecting the limiter and the limit screw to form a whole through the second adjusting nut, the vertical positioning of the multi-stage drop plate template system is accurately ensured, and the rigidity of the template is increased.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] Example 1
[0036] like Figures 1 to 3As shown, this embodiment provides a one-time forming device for a multi-level drop sill in a multi-water room, including: a support frame 1; a positioning component 2 for positioning the support frame 1; one end of the positioning component 2 is disposed on the support frame, and the other end of the positioning component 2 is connected to the floor support surface 4; a limiting component 3 for multi-level vertical limiting of the support frame 1; one end of the limiting component 3 is disposed on the support frame, and the other end of the limiting component 3 is connected to the multi-level drop sill area of the floor.
[0037] In this embodiment, a floor slab support surface 4 area and a multi-level drop slab area are provided on the floor slab, wherein the floor slab support surface 4 area is located on both sides of the floor slab, and the multi-level drop slab area is located in the middle part sandwiched between the two sides of the floor slab support surface 4 area (see...). Figure 1 Positioning components 2 are set on both sides of the support frame 1 and connected to the floor support surface 4 area, solving the problem of no fixed points in the area of suspended formwork; multiple limiting components 3 are set on the support frame 1 and connected to the multi-level drop slab area of the floor slab. The multiple limiting components 3 are used to vertically position the multi-level drop slab area at different heights on the corresponding floor slab. The support frame 1 can be formed in one go after determining the design shape according to the position of the drop slab and the countersill, which greatly reduces the probability of secondary repair after casting and reduces construction costs; after the drop slab position to be constructed is completed, the one-time forming device can be removed by loosening the nuts in each area, which is convenient for disassembly and assembly.
[0038] Furthermore, the support frame 1 includes: a horizontal square tube 11, and a plurality of vertical square tubes 12 corresponding to the multi-level drop slab areas of the floor slab; the plurality of vertical square tubes 12 are all disposed on the horizontal square tubes 11. The vertical square tubes 12 are disposed on the horizontal square tubes 11 by welding and / or bolting.
[0039] In this embodiment, the support frame 1 is formed by connecting horizontal square tubes 11 and multiple vertical square tubes 12. The multiple vertical square tubes 12 can be fixed to the horizontal square tubes 11 by welding or bolting. The support frame 1 is designed according to the position of the drop plate and the curb, and is easy to adjust. The two ends of the horizontal square tubes 11 are fixed to the anchoring position of the floor support surface 4 by positioning components 2.
[0040] Furthermore, the positioning component 2 includes: a positioning screw 21 and a plurality of first adjusting nuts 22 corresponding to and adapted to the positioning screw 21; one end of the positioning screw 21 is disposed on the support frame, and the other end of the positioning screw 21 is connected to the floor support surface 4; the plurality of first adjusting nuts 22 are movably disposed on the positioning screw 21.
[0041] In this embodiment, the positioning screw 21 is made by threading the entire length of the screw. The upper end passes through the anchor position of the transverse square tube 11 through a drilled hole, and the lower end passes through the floor support surface 4 through a drilled hole in the template support system. The first adjusting nut 22 is movably mounted on the positioning screw 21 and abuts against the transverse square tube 11. Then, the positioning screw 21 is positioned by tightening the nut. The positioning screw 21 adjusts the overall positioning and elevation of the device through the first adjusting nut 22.
[0042] Furthermore, a positioning wooden template 23 and a first reinforcing wooden block 24 corresponding to and adapted to the positioning wooden template 23 are provided at the connection between the positioning screw 21 and the floor support surface 4.
[0043] In this embodiment, a matching positioning wooden template 23 and a first reinforcing wooden block 24 are provided at the connection between the positioning screw 21 and the floor slab support surface 4 (the wooden template 23 and the first reinforcing wooden block 24 constitute a wooden template system). The lower end of the positioning screw 21 passes through the wooden template 23 and the first reinforcing wooden block 24, and the wooden template system is lowered and positioned by tightening the nut to ensure the accurate horizontal position of the device.
[0044] Furthermore, a PVC sleeve 6 is provided on the positioning screw 21 to separate the floor support surface 4.
[0045] In this embodiment, a PVC sleeve 6 is provided at the position where the positioning screw 21 connects to the floor slab support surface 4. In order to prevent the positioning screw 21 from being unable to be removed from the floor slab support surface 4 after the concrete is poured and solidified, the PVC sleeve 6 can separate the positioning screw 21 and the floor slab support surface 4, which facilitates the turnover construction after the positioning screw 21 is removed.
[0046] Furthermore, the limiting component 3 includes: a limiter 31, a limiting screw 32, and a plurality of second adjusting nuts 33 corresponding to and adapted to the limiting screw 32; the limiting screw 32 is disposed on the transverse square tube 11; one end of the limiter 31 is connected to the vertical square tube 12, and the other end of the limiter 31 is connected to the limiting screw 32; the plurality of second adjusting nuts 33 are all movably disposed on the limiting screw 32.
[0047] In this embodiment, the limiting screw 32 is made by threading the entire length of the screw. The upper end passes through the horizontal square tube 11 through a drilled hole, and the lower end is connected to the vertical square tube 12 of the support frame 1 through the limiting device 31 and the second adjusting nut 33. The limiting device 31 is welded to the vertical square tube 12, and the limiting device 31 and the limiting screw 32 are connected as a whole through the second adjusting nut 33, thereby ensuring the vertical positioning of the multi-stage dropping plate template system and increasing the rigidity of the template, thus ensuring the molding quality.
[0048] Furthermore, a second reinforcing timber 51 is provided on the limiter 31; a limiting timber template 52 is provided on the second reinforcing timber 51; the limiting timber template 52 connects to the multi-level drop area of the floor slab.
[0049] In this embodiment, the second reinforcing timber 51 and the limiting timber template 52 constitute a timber template system. The limiting screw 32 is connected to the multi-level lowering template system on the floor through the limiter 31 and the timber template system, so that the entire multi-level lowering template system can be hung on the support frame 1.
[0050] Furthermore, the length of the limiting screw 32 is adapted to that of the vertical square tube 12.
[0051] In this embodiment, the lengths of the limiting screw 32 and the vertical square tube 12 correspond, thereby matching the connection relationship between the limiting screw 32 and the vertical square tube 12.
[0052] Furthermore, the cross-sectional shape of the limiter 31 is L-shaped.
[0053] In this embodiment, the cross-sectional shape of the limiter 31 is L-shaped (see...). Figure 3 This allows the limiter 31 to have space to accommodate the second adjusting nut 33.

[0062] In this embodiment, the support frame 1 is composed of multiple sections of square tubing welded or bolted together. The two ends of the support frame 1 are fixed, positioned and their elevation controlled at the anchoring positions on the floor slab by tightening the first adjusting nut 22 on the positioning screw 21 and the lower end is connected to the floor slab of the template support system.
[0063] Assemble a multi-stage drop slab formwork system at the proposed drop slab location. Install a limiting screw 32 through the multi-stage drop slab formwork system and use a second adjusting nut 33 to hang and position the formwork system.
