[0023] The present invention is described clearly and completely below in conjunction with the accompanying drawings. A person skilled in the art will be able to implement the present invention based on these descriptions.

[0025] The embodiments of the present invention involved in the following description are generally only a part of the embodiments rather than all the embodiments. Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of patent protection.

[0027] Aluminum alloy formwork is mainly composed of wall main formwork (such as Figure 1 As shown in the figure), floor formwork, supporting reinforcement parts, etc., can realize the overall construction of the building structure and effectively improve the construction quality and efficiency. However, in actual application, the joints between the bottom of the main wall formwork and the floor often have problems such as poor sealing and insufficient sealing, which leads to concrete slurry leakage, honeycombs, holes and other quality defects at the root of the wall, forming the so-called "rotten root" phenomenon (see Figure 2As shown in the figure, a lot of manpower and material resources are needed for later repair, which significantly increases the project cost and construction period. For the problem of "root rot", the current solution is mainly to adopt "mortar plugging", that is, to use mortar to seal the joints between the bottom of the main wall formwork and the floor. However, this method has many problems: the sealing effect is unreliable; the mortar plugging operation process is cumbersome and requires a lot of manual operation, which not only has low construction efficiency, but also makes it difficult to ensure the construction quality, and new leakage points are often generated due to local poor sealing; additional construction processes are added, resulting in material waste and increased labor costs, and the rework rate is high, which seriously affects the construction progress and project quality.

[0028] Figure 3 This is a schematic diagram of a concrete engineering aluminum alloy formwork wall root anti-leakage structure of the present invention. Figure 3 As shown, the anti-leakage structure of the wall root of the aluminum alloy formwork for concrete engineering includes: a wall root forming formwork 2, which is detachably installed at the bottom of the wall main formwork 1 and is used to seal the bottom of the wall main formwork 1 so that a regular inner angle line is formed at the wall root after forming; and a wall root forming formwork positioning structure, which is connected between the wall root forming formwork 2 and the wall main formwork 1, and is used to keep the wall root forming formwork 2 at the set position at the bottom of the wall main formwork 1 and apply a preset pressure downward and into the wall to the wall root forming formwork 2.

[0029] Specifically, a first horizontal flange 11 is provided at the bottom of the main wall formwork 1, and a second horizontal flange 21 is provided at the top of the wall root forming formwork 2. A nut 12 is provided on the first horizontal flange 11. The second horizontal flange 21 is stacked on the lower surface of the first horizontal flange 11 and is detachably connected by a bolt 3 passing through the first horizontal flange 11 and the second horizontal flange 21 and through the nut 12, so that the inner side surface of the wall root forming formwork 2 is flush with the inner side surface of the main wall formwork 1; a first pressing block 4 is provided at the lower end of the bolt 3, and the first pressing block 4 contacts with the outer side surface of the wall root forming formwork 2 to apply a preset pressure downward and inward to the wall to the wall root forming formwork 2, and a screw hole is provided in the first pressing block 4 (the screw hole is located in the rotary seat 41), and the lower end of the bolt 3 is threadedly adapted to the corresponding screw hole in the first pressing block 4.

[0030] The bottom surface of the first pressing block 4 and the part of the first pressing block 4 that contacts the outer side surface of the wall base forming template 2 are paved with a rubber cushion layer 42. The first pressing block 4 is made of aluminum alloy profiles. There are multiple bolts 3 and the bolts 3 are spaced apart along the length direction of the first horizontal flange 11 and the second horizontal flange 21, and the lower ends of the bolts 3 are respectively matched with the corresponding screw holes in the first pressing block.

[0031] Figure 3 The working principle of the concrete engineering aluminum alloy formwork wall root anti-leakage structure shown is: the second horizontal flange 21 at the top of the wall root forming formwork 2 is matched with the first horizontal flange 11 at the bottom of the wall main formwork 1 in a stacked manner, and a reliable connection is achieved by a plurality of bolts 3 and nuts 12 arranged at intervals along the length direction of the first horizontal flange 11 and the second horizontal flange 21, especially through the action mechanism of the first pressing block 4, the screw hole therein is adapted to the threaded connection of the bolt 3, and when tightened, a preset pressure is simultaneously generated downward and inward on the wall to the wall root forming formwork 2, ensuring that the wall root forming formwork 2 is tightly fitted with the wall main formwork 1, and the inner side surface of the wall root forming formwork 2 is kept flush with the inner side surface of the wall main formwork 1; at the same time, the rubber pad 42 arranged on the bottom surface of the first pressing block 4 and the contact part with the outer side surface of the wall root forming formwork 2 further enhances the sealing effect. The connection method between the first pressure block 4 made of aluminum alloy profile and the bolt 3 makes installation and disassembly convenient, without the need for special tools and professional techniques, simplifies the construction process, and eliminates the traditional mortar caulking step; the spaced arrangement of multiple bolts 3 ensures uniform force, and the elastic seal provided by the rubber cushion layer 42 effectively prevents local leakage.

[0032] In addition, it is also necessary to emphasize that the first pressing block 4 not only has a sealing function in the aluminum alloy formwork system, but also plays a supporting role: the first pressing block 4 is in close contact with the outer side of the wall root forming formwork 2, applying a preset pressure downward and inward to the wall. This two-way force not only ensures the stable connection between the wall root forming formwork 2 and the wall main formwork 1, but also provides reliable supporting force, effectively resisting the lateral pressure and upward lifting force generated during the concrete pouring process; in addition, through the threaded adaptation connection between the bolt 3 and the screw hole in the first pressing block 4, a stable mechanical connection structure is formed, which can bear the dead weight of the aluminum alloy formwork system and effectively prevent the root forming formwork 2 from being deformed by force.

[0033] Figure 4 This is another schematic diagram of the anti-leakage structure of the aluminum alloy formwork wall base of the concrete engineering of the present invention. Figure 4 As shown, the anti-leakage structure of the wall root of the aluminum alloy formwork for concrete engineering includes: a wall root forming formwork 2, which is detachably installed at the bottom of the wall main formwork 1 and is used to seal the bottom of the wall main formwork 1 so that a regular inner angle line is formed at the wall root after forming; and a wall root forming formwork positioning structure, which is connected between the wall root forming formwork 2 and the wall main formwork 1, and is used to keep the wall root forming formwork 2 at the set position at the bottom of the wall main formwork 1 and apply a preset pressure downward and into the wall to the wall root forming formwork 2.

[0034] Specifically, the wall base forming template 2 is composed of a second pressing block 5; the second pressing block 5 has a side plate 51, a bottom plate 52 and a force-bearing structure 53 (using connecting ribs or connecting plates) connected between the side plate 51 and the bottom plate 52, the side plate 51 serves as the wall base forming template 2, the bottom plate 52 is placed on the ground, and the force-bearing structure 53 is used to receive the preset downward and inward pressure applied to the second pressing block 5 by the wall base forming template positioning structure.

[0035] The wall base forming template positioning structure includes a cantilever 13 arranged on the outer side of the wall main template 1 and an oblique screw hole opened on the cantilever 13, a screw rod 6 is threadedly installed in the oblique screw hole, the screw rod 6 is inclinedly arranged and the head of the screw rod 6 is pressed on the force-bearing structure 53, and the screw rod 6 applies a preset downward and inward pressure to the second pressing block. In addition, the number of the cantilever 13 and the screw rod 6 is multiple and these screw rods 6 are arranged at intervals along the length direction of the second pressing block 5, and the lower ends of these screw rods 6 are pressed on the corresponding force-bearing structures 53 respectively.

[0036] In this embodiment, the side panel 51 directly serves as the wall base forming template 2, and provides stable support through the contact with the ground by the bottom plate 52, and the force-bearing structure 53 cleverly connects the side panel 51 and the bottom plate 52 to form an overall force-bearing system; in particular, the wall base forming template positioning structure adopts a combination of multiple cantilevers 13 and screws 6 arranged at intervals along the length direction. Through the inclined setting of the screw 6 in the oblique screw hole, when the head of the screw 6 is pressed on the force-bearing structure 53, it can simultaneously generate a preset pressure downward and toward the wall. This structure not only simplifies the installation process, but also ensures the reliability of the sealing effect through multi-point force; at the same time, the integral design of the second pressing block 5 avoids the installation difficulty caused by too many parts, and the setting of the bottom plate 52 provides a reliable support foundation.

[0037] Figure 5 For Figure 4 Schematic diagram of the improved wall base forming template. Figure 5 As shown, through the well, the side plate 51 has a step structure, which is composed of a first side wall 51a, a second side wall 51b and a horizontal plane connected between the first side wall 51a and the second side wall 51b. The first side wall 51a is in contact with the outer side wall of the main wall formwork 1, and the second side wall 51b is flush with the inner side surface of the main wall formwork 1.

[0038] Among them, the first side wall 51a is in contact with the outer wall of the main wall formwork 1, providing reliable support and positioning reference to ensure installation accuracy; the second side wall 51b is flush with the inner side of the main wall formwork 1, which not only ensures the flatness of the wall after forming, but also forms a regular inner corner line; and the horizontal plane between the two side walls forms a transfer transition zone. This stepped design increases the structural strength and provides better anti-deformation ability. At the same time, it can more effectively withstand and transmit the preset pressure applied downward and inward by the screw 6, further improving the sealing performance and stability of the entire system.

[0039] The above is a description of the relevant contents of the present invention. A person skilled in the art will be able to implement the present invention based on these descriptions. Based on the above contents of this specification, all other embodiments obtained by a person skilled in the art without making any creative work shall fall within the scope of patent protection.
