DETAILED DESCRIPTION

[0031] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] See also Figure 1-6A pre-embedded adjustable wall base anti-leakage and water return device includes right-angle fixing frames 1 arranged symmetrically along both sides of the wall surface. The bottom surface of the right-angle fixing frame 1 is attached to the ground, and a hydrophobic plate 2 is attached to the inner side of the facade. A plurality of grounding bolt holes 11 are provided at intervals on the bottom surface of the right-angle fixing frame 1 for use in bolting the right-angle fixing frame 1. The right-angle fixing frame 1 and the hydrophobic plate 2 are detachable, which facilitates separation during demoulding, allowing the hydrophobic plate 2 to be pre-embedded at the base of the building wall, thereby achieving the function of waterproofing and preventing slurry leakage.

[0033] The vertical surfaces of the right-angle fixing frames 1 on the left and right sides are clamped and fastened by passing through tension bolts 3. There are multiple groups of tension bolts 3, which are spaced apart along the length direction of the right-angle fixing frame 1. A wall formwork 8 is connected to the top of the hydrophobic plate 2. The outer wall of the hydrophobic plate 2 is flush with the inner wall of the wall formwork 8. A formwork fixing plate 5 is provided on the top of the vertical surface of the right-angle fixing frame 1. The formwork fixing plate 5 is attached to the outside of the wall formwork 8 for positioning and assisting in fixing the wall formwork 8.

[0034] A receiving groove 4 is provided at the top of the vertical surface of the right-angle fixing frame 1 along its length direction. A template fixing plate 5 is inserted into the receiving groove 4. The template fixing plate 5 can be lifted and moved in the receiving groove 4. When supporting the formwork, the template fixing plate 5 can be pulled out of the receiving groove 4 to be used for positioning and auxiliary fixing of the wall formwork 8. When removing the formwork after use, the template fixing plate 5 is lowered and retracted into the receiving groove 4, thereby realizing the integrity of the device, avoiding the dispersion of components, and facilitating the transfer and storage of the device.

[0035] Furthermore, it also includes a lifting linkage mechanism for supporting the template fixing plate 5 to move up and down in the accommodating groove 4. Specifically, the linkage mechanism includes a fixed waist circular groove 41 and a movable waist circular groove 51 respectively provided on the side wall of the accommodating groove 4 and the template fixing plate 5. The front and rear positions of the fixed waist circular groove 41 and the movable waist circular groove 51 are consistent, but the upper and lower relative positions can be staggered. A fixed gear 6 is provided in the fixed waist circular groove 41 and the movable waist circular groove 51. The fixed gear 6 is rotatably installed on the inner wall of the accommodating groove 4 through the gear shaft 61. A fixed groove rack 42 and a movable groove rack 42 meshing with the fixed gear 6 are respectively provided on different side walls of the fixed waist circular groove 41 and the movable waist circular groove 51. When the template fixing plate 5 is lifted or lowered, the fixed slot rack 42 and the movable slot rack 52 are simultaneously meshed with the fixed gear 6 on both sides for transmission. The fixed gear 6 plays a linkage role between the template fixing plate 5 and the receiving groove 4, and limits the template fixing plate 5 to only be able to move vertically in the receiving groove 4, thereby improving the reliability of the device. This embodiment does not show the fixing scheme after the template fixing plate 5 is lifted. The fixing scheme is given in this case because the template fixing plate 5 mainly plays the role of constraining the lower end position of the wall template 8. The wall template 8 itself can give the template fixing plate 5 a reaction force, and the use of two contact friction forces can also meet the fixing requirements. In actual use, if it cannot be fixed well due to special reasons, holes can be opened at the corresponding positions of the receiving groove 4 and the template fixing plate 5 in the rising state and positioning pins can be inserted to achieve effective fixation.

[0036] Since the device is overmolded, the bolt holes on the hydrophobic plate 2 and the tension bolts 3 cannot achieve an absolute waterproof seal. If seepage occurs at the double holes, in severe cases, the nuts and screws of the tension bolts 3 may rust, which will affect the connection strength of the bolts over time, posing a certain risk of damage. Therefore, another embodiment is provided below:

[0037] A glue-filled seal 7 is provided between the two ends of the tension bolt 3 and the outer wall of the hydrophobic plate 2. Specifically, the glue-filled seal 7 includes a seat body 71, and a cavity 72 for injecting sealant is provided inside the seat body 71. Tension bolt holes 73 are provided through the left and right side walls of the glue-filled seal 7, and injection holes 74 are provided on the upper and lower or front and rear side walls of the glue-filled seal 7. After demolding, the glue-filled seal 7 device is embedded between the nut of the tension bolt 3 and the outer wall of the hydrophobic plate 2, and the internal cavity 72 of the glue-filled seal 7 can be used to inject sealant. The sealant can effectively cover the screw of the tension bolt 3 and fill each bolt hole, thereby preventing internal water from overflowing and contacting the thread at the connection between the nut and the screw, thereby causing rust.

[0038] Based on the above-mentioned pre-buried adjustable wall root anti-leakage slurry and water return device, the following construction method is provided:

[0039] Positioning: Locate and locate the wall construction position;

[0040] Formwork: Set up right-angle fixing frames 1 on both sides of the wall. Use tension bolts 3 to clamp and fasten the right-angle fixing frames 1 on both sides. Attach a hydrophobic plate 2 to the inner wall of the right-angle fixing frame 1. Set up a wall formwork 8 on the top of the right-angle fixing frame 1 and lift the formwork fixing plate 5 to attach it to the outside of the wall formwork 8. At the same time, seal both ends of the mold cavity.

[0041] Pouring: Lay a layer of cement mortar on the bottom of the mold cavity, then continue to pour the wall on the cement mortar and wait for the wall to solidify;

[0042] Dismantling the formwork: except for the tension bolts 3 and the hydrophobic plate 2, remove the remaining components;

[0043] Sealing: Install glue-potting sealants 7 at both ends of the tension bolt 3 to perform thread sealing; the specific installation steps of the glue-potting sealant 7 are: first remove the nuts and gaskets at both ends of the tension bolt 3, then fit the tension bolt hole 73 of the glue-potting sealant 7 with the screw end of the tension bolt 3, and then re-lock the nut and gasket and tighten them; finally, inject sealant through the pouring hole 74 of the glue-potting sealant 7 until the sealant overflows from the other pouring hole 74, and then use tape to temporarily wrap and seal at least one of the pouring holes 74, and remove the tape after the sealant solidifies.

[0044] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
