[0002] In order to prevent and control floor leakage in residential projects and respond to regulations on the prevention and control of common quality problems in residential projects, it is necessary to set concrete waterproof anti-edges with the same wall width and a height not less than 200mm above the relatively higher ground of adjacent rooms on the surrounding walls of rooms with water, such as bathrooms, kitchens, balconies, and equipment platforms. In order to ensure the anti-seepage effect, no horizontal construction joints should be left between the waterproof anti-edge and the floor slab, that is, the anti-edge must be formed in one go.

[0003] In accordance with regulations for preventing water leakage in rooms with water, aluminum formwork generally provides superior quality for counter-bumps than wooden formwork. However, due to difficulties in formwork positioning, the quality of the counter-bumps formed in a single pour of concrete in rooms with water is generally poor. Therefore, optimizing the fixing method for the counter-bump formwork is urgent.

[0004] Existing methods for positioning and securing aluminum formwork on floor slabs include: 1. Welding the formwork with positioning steel bars to the floor slab reinforcement; 2. Drilling holes in the formwork and securing it with screws and angle steel. These methods have the following drawbacks: 1. The floor slab reinforcement is prone to misalignment, causing the slab to expand and float, resulting in poor slab forming quality and significant positioning deviation; 2. Filling floor holes is difficult and affects the waterproofing of rooms exposed to water. Utility Model Content

[0021] The accompanying drawings in this specification are schematic diagrams that assist in illustrating the concepts of the present invention and schematically illustrate the shapes of the various components and their interrelationships. Please note that to clearly illustrate the structures of the various components of the embodiments of the present invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0022] The following describes the principles and features of the present invention in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-3 (In order to avoid obstruction of components, Figure 2 and Figure 3 (Some components are not shown), the preferred embodiment of the utility model is further described in detail:

[0023] like Figure 1-3As shown, the utility model preferably adopts a non-opening aluminum formwork anti-floating fixing system, including a supporting assembly and a tensioning assembly, the supporting assembly includes a limiting pier 13 and a positioning steel bar 14, the limiting pier 13 is arranged at intervals along the anti-ridge aluminum formwork 6, the bottom end of which is against the floor aluminum formwork 5, and the top end thereof supports the anti-ridge aluminum formwork 6. Since the floor aluminum formwork 5 has a higher stability than the plate surface steel bar 12, this measure can effectively improve the position stability of the anti-ridge aluminum formwork 6, for the convenience of production and ease of use. From the perspective of installation and improving the stability after installation, the limiting pier 13 should be a prefabricated concrete prism structure with a large bottom and a small top, and the inner side of the limiting pier 13 should be flush with the inner side of the anti-canopy aluminum form 6, and the bottom is fixed on the plate surface steel bar 12 in the form of welding or binding, and its top is against the bottom of the anti-canopy aluminum form 6 on the inner side of the anti-canopy aluminum form 6. The tensioning assembly includes a tensioning support beam 7 and a support screw 1. The tensioning support beam 7 is set on the top of the anti-canopy aluminum form 6 and is connected to the anti-canopy aluminum form 6 on both sides. The support screw 1 is fixedly connected in a detachable manner by pins and pins. The support screw 1 is vertically arranged in the anti-ridge casting space. A hook 3 is welded and fixed to the bottom end of the support screw 1, and the hook 3 hooks the tension screw 4 at the beam / wall aluminum mold 8. A fastening nut 2 is provided on the top of the support screw 1. The support screw 1 passes through the tension support beam 7 and cooperates with the fastening nut 2 at the top surface of the tension support beam 7 to press the tension support beam 7 to the top surface of the anti-ridge aluminum mold 6. The support screw 1 plays a role of tensioning and fixing in this structural system. The bottom end thereof pulls the tension screw 4 through the hook 3 to form a tension fixing point, and the top end thereof tightens and fixes the tension support beam 7 to the top surface of the anti-ridge aluminum form 6 through the fastening nut 2, thereby cooperating with the support component to achieve the fixing effect of pressing up and pushing down on the anti-ridge aluminum form 6, effectively avoiding the displacement problems such as mold expansion and floating of the anti-ridge aluminum form 6 during the pouring process. Moreover, the fastening nut 2 can adjust the length of the support screw 1 embedded in the concrete anti-ridge structure, thereby making it adaptable to different floor slab heights and anti-ridge height requirements;

[0024] In order to avoid the problem of slippage after the hook 3 hooks the tension screw 4, in some preferred embodiments, the section of the tension screw 4 where the hook 3 is hung needs to be provided with an external thread, for example, the tension screw 4 adopts a through-thread screw;

[0025] The tension support beam 7 is preferably made of angle steel, with its vertical plate facing upward and its horizontal plate placed horizontally on the top of each anti-ridge aluminum mold 6, and a number of groups of through holes for passing the support screws 1 are provided on the upper length direction of the horizontal plate at a certain module interval, so that it can adapt to anti-ridge construction of different widths. On this basis, a downward extending limit vertical rod 15 is also vertically fixed to the end of one side of the tension support beam 7. The limit vertical rod 15 made of steel pipe is against the outer facade of the anti-ridge aluminum mold 6. On the one hand, the limit vertical rod 15 can make the through holes on the tension support beam 7 more convenient to align with the through holes on the anti-ridge aluminum mold 6. On the other hand, it can also exert a certain anti-lateral displacement ability, and to a certain extent avoid the problem of mold expansion of the anti-ridge aluminum mold 6.

[0026] In the present invention, the support screw 1 and the hook 3 remain in the concrete structure after pouring, and the fastening nut 2 is removed together with the formwork. After the tension support beam 7 at the top of the counter-step is removed, the part of the support screw 1 that is higher than the counter-step structure needs to be cut off.

[0027] During construction, the reinforcement workers first tie the shear wall reinforcement, followed by the formwork workers assembling the beam / wall aluminum formwork 8. Once the beam / wall aluminum formwork 8 is in place, the formwork is initially secured with pins. The horizontal back ribs 10 are then installed. The beam / wall tensioning screws 4 are inserted through the pre-reserved tensioning holes in the beam / wall aluminum formwork 8 and anchored with independent nuts 9 at both ends. After the beam / wall aluminum formwork 8 is installed, the floor slab aluminum formwork 5 is positioned and secured. Once the lower formwork is securely installed, the formwork can be moved onto the floor slab aluminum formwork 5 to tie the protective layer pads 16, the slab reinforcement 12, and the lower beam reinforcement.

[0028] After the slab reinforcement 12 is tied, the positioning reinforcement 14 is welded at the corresponding position according to the layout and the limiting piers 13 are placed along the layout position. After that, the anti-ridge aluminum formwork 6 is in place and preliminarily fixed with pins. Before the support screw 1 enters the site, the hook 3 needs to be welded to its end in advance for use. During construction, first pass the end of the support screw 1 without the hook through the bolt hole reserved in the middle of the tension support beam 7, and pre-tighten it with the fastening nut 2. Afterwards, the tension support beam 7 together with the support screw 1 and the hook 3 is installed on the top of the anti-ridge aluminum formwork 6. Its plane position corresponds to the lower beam / wall tension screw 4. The limiting vertical rod 15 is in close contact with the vertical back rib 11 at the anti-ridge aluminum formwork 6, and the hook 3 is hooked on the beam / wall tension screw 4.

[0029] After the top tension support beam 7 of the anti-slope is firmly installed using pins, the installation construction can be completed by anchoring the fastening nut 2.

[0030] After the concrete pouring is completed, first unscrew the fastening nut 2 and remove the fixing pins between the tension support beam 7 and the anti-ridge aluminum formwork 6, remove the tension support beam 7, and then remove the anti-ridge aluminum formwork 6. After that, cut off the part of the support screw 1 that is higher than the anti-ridge surface. When removing the lower formwork, first loosen the tension nut 9 at the end of the tension screw 4, and use tools to knock out the beam / wall tension screw 4 from one side of the beam / wall aluminum formwork 8 (if it is a three-stage water-stop screw, just unscrew the water-stop screws on both sides directly with the tool), then remove the horizontal back rib 10 at the beam / wall aluminum formwork 8, the beam / wall aluminum formwork 8 and the floor slab aluminum formwork 5 in turn, and then transport the aluminum formwork to the next floor to continue construction.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
