Description

Technical Field

[0001] This utility model relates to the field of aluminum formwork construction technology, specifically to a grout sealing device for the bottom of aluminum alloy formwork used in construction to prevent grout leakage. Background Technology

[0002] In the field of modern construction, aluminum alloy formwork has been widely used due to its significant advantages such as light weight, high strength, reusability, high construction efficiency, and good forming quality. However, in actual construction, the problem of sealing the gaps at the bottom of aluminum alloy formwork has always been a difficult issue for construction workers. If not handled properly, grout leakage can easily occur, which will adversely affect the quality and progress of the construction project.

[0003] Chinese patent CN216076342U discloses a sealing device for the bottom of an aluminum alloy interior wall formwork. This sealing device utilizes the properties of soft rubber sheets to allow for the normal installation of the aluminum alloy interior wall formwork even when there are height errors in the structural floor after concrete is poured on site. It can also effectively control issues such as grout leakage, root rot, and unsanitary construction on the interior wall formwork.

[0004] When the above-mentioned patent is used, if there is a large height error in the structural floor, the fixed size of the angle aluminum will result in a large gap between the bottom of the angle aluminum and the structural floor. Since the soft rubber sheet lacks sufficient support from the angle aluminum, the force generated during the pouring process will cause the bottom of the soft rubber sheet to curl up, which will easily lead to grout leakage and adversely affect the quality and progress of the construction project. Utility Model Content

[0005] The purpose of this utility model is to provide a grout sealing device for the bottom of aluminum alloy formwork in construction, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A grout sealing device for the bottom of aluminum alloy formwork in construction includes an aluminum alloy inner wall formwork, an angle aluminum, and a soft rubber sheet. The angle aluminum is installed at the bottom of the aluminum alloy inner wall formwork, and the soft rubber sheet is installed on one side of the short side of the angle aluminum, with the soft rubber sheet flush with the inner side of the aluminum alloy inner wall formwork. A support plate is installed at the bottom of the short side of the angle aluminum via a lifting mechanism, which can adjust the height of the support plate vertically.

[0008] Therefore, by setting up the lifting mechanism, when there is a large height error in the structural floor, the height of the support plate can be adjusted accordingly, so that the support plate can provide support for the lower part of the soft rubber sheet. This avoids the situation where the bottom edge curls up and leaks grout during pouring due to lack of support at the bottom, thus ensuring the quality and progress of the construction project.

[0009] Furthermore, the lifting mechanism includes an L-shaped guide rod connected to the outer surface of the support plate. One end of the vertical rod of the L-shaped guide rod is vertical and slides through to the upper side of the long side of the angle aluminum. A lifting plate is installed at the end of the vertical rod of the L-shaped guide rod. A first bolt is rotatably connected to the upper surface of the angle aluminum. The first bolt passes through the interior of the lifting plate and is threadedly connected to it.

[0010] Furthermore, several pin holes are formed on the long side of the angle aluminum, and several through holes are formed on the short side of the angle aluminum. Connecting posts that are compatible with the through holes are installed on the outer surface of the soft rubber sheet. A screw hole is formed at the end of the connecting post, and a second bolt is installed inside the screw hole.

[0011] Furthermore, serrated grooves are evenly provided on the short side of the angle aluminum, and serrated blocks that match the serrated grooves are evenly provided on the upper surface of the support plate.

[0012] Furthermore, multiple L-shaped guide rods are provided, and the multiple L-shaped guide rods are distributed at equal intervals, with the first bolt located in the middle of the lifting plate.

[0013] Furthermore, the length of the connecting post is consistent with the thickness of the short side of the angle aluminum.

[0014] Furthermore, a diagonal brace is provided at the corner of the L-shaped guide rod.

[0015] Furthermore, the two ends of the L-shaped guide rod are connected to the support plate and the lifting plate by welding, respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. By setting up a lifting mechanism, this utility model can adjust the height of the support plate accordingly when there is a large height error in the structural floor, so that the support plate can provide support for the lower part of the soft rubber sheet, thereby avoiding the situation of grout leakage at the bottom edge during pouring due to lack of bottom support, and ensuring the quality and progress of the construction project.

[0018] 2. By setting sawtooth grooves and sawtooth blocks, this utility model provides uniform support to the support plate when the height of the support plate is lowered. This ensures that the soft rubber sheet is subjected to uniform force, avoids local deformation during casting, and improves the uniformity of the surface of the cast part.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a grout sealing device for the bottom of aluminum alloy formwork for construction, including an aluminum alloy inner wall formwork 1, an angle aluminum 2, and a soft rubber sheet 3. The angle aluminum 2 is installed at the bottom of the aluminum alloy inner wall formwork 1, and the soft rubber sheet 3 is installed on one side of the short side of the angle aluminum 2, and the soft rubber sheet 3 is flush with the inner side of the aluminum alloy inner wall formwork 1. A support plate 4 is installed at the bottom of the short side of the angle aluminum 2 through a lifting mechanism 5, and the lifting mechanism 5 can adjust the height of the support plate 4 in the vertical direction.

[0027] In use, the soft rubber sheet 3 is installed on the short side of the angle aluminum 2, and the angle aluminum 2 is installed at the bottom of the aluminum alloy inner wall formwork 1. After multiple aluminum alloy inner wall formworks 1 are assembled to form a cavity for pouring, the support plate 4 can be lowered by the lifting mechanism 5 so that its bottom contacts the structural floor surface. At this time, the support plate 4 provides support for the lower part of the soft rubber sheet 3. When pouring is carried out later, the bottom of the soft rubber sheet 3 is supported, which can prevent the bottom edge from curling up and causing grout leakage, thus ensuring the quality and progress of the construction project. Furthermore, since the height of the support plate 4 is adjustable, it can be prevented from contacting the structural floor surface when disassembling and assembling the aluminum alloy inner wall formwork 1, avoiding frictional resistance that could lead to disassembly difficulties.

[0028] Preferably, the lifting mechanism 5 includes an L-shaped guide rod 501 connected to the outer surface of the support plate 4. One end of the vertical rod of the L-shaped guide rod 501 is vertical and slides through to the upper side of the long side of the angle aluminum 2. A lifting plate 502 is installed at the end of the vertical rod of the L-shaped guide rod 501. A first bolt 503 is rotatably connected to the upper surface of the angle aluminum 2. The first bolt 503 passes through the interior of the lifting plate 502 and is threadedly connected to it.

[0029] When the height of the support plate 4 is adjusted, the first bolt 503 can be rotated. Since the lifting plate 502 is limited by the L-shaped guide rod 501, the lifting plate 502 can be driven to rise and fall vertically under the action of the threaded connection. And through the connection of the L-shaped guide rod 501, the vertical lifting of the support plate 4 can be achieved.

[0030] Preferably, the long side of the angle aluminum 2 is provided with a plurality of pin holes 6, and the short side of the angle aluminum 2 is provided with a plurality of through holes 601. A connecting post 602 adapted to the through holes 601 is installed on the outer surface of the soft rubber sheet 3. A screw hole 603 is provided at the end of the connecting post 602, and a second bolt 604 is installed inside the screw hole 603.

[0031] With the pin hole 6, the angle aluminum 2 can be fixedly installed at the bottom of the aluminum alloy inner wall template 1 using pins. When installing the soft rubber sheet 3, the connecting column 602 can be inserted into the through hole 601, and then the second bolt 604 can be screwed into the screw hole 603 to install the soft rubber sheet 3, ensuring that the surface of the soft rubber sheet 3 is smooth and flat and improving the pouring quality.

[0032] Preferably, the short side of the angle aluminum 2 is uniformly provided with serrated grooves 7, and the upper surface of the support plate 4 is uniformly provided with serrated blocks 701 that are adapted to the serrated grooves 7.

[0033] By setting the serrated grooves 7 and serrated blocks 701, when the height of the support plate 4 is lowered, the staggered serrated grooves 7 and serrated blocks 701 provide uniform support for the support plate 4, so that the soft rubber sheet 3 is subjected to uniform force, avoiding local deformation during casting and improving the uniformity of the surface of the cast part.

[0034] Preferably, there are multiple L-shaped guide rods 501, and the multiple L-shaped guide rods 501 are distributed at equal intervals, and the first bolt 503 is located in the middle of the lifting plate 502.

[0035] By setting multiple L-shaped guide rods 501, not only is the limiting effect on the lifting plate 502 improved, enabling it to rise and fall smoothly, but it also provides stronger support for the support plate 4, preventing the support plate 4 from becoming loose under the action of concrete during pouring.

[0036] Preferably, the length of the connecting post 602 is the same as the thickness of the short side of the angle aluminum 2.

[0037] Because the soft rubber sheet 3 has a certain deformation capacity, if the length of the connecting column 602 is shorter than the thickness of the short side of the angle aluminum 2, when the second bolt 604 is tightened, the end face of the connecting column 602 will abut against the end face of the second bolt 604, causing the connecting column 602 to exert a pulling effect on the soft rubber sheet 3. This results in unevenness on one side of the soft rubber sheet 3 during casting, affecting the casting quality. Therefore, by making the length of the connecting column 602 consistent with the thickness of the short side of the angle aluminum 2, the pulling effect on the soft rubber sheet 3 can be avoided, ensuring the integrity of its structure and improving the casting quality.

[0038] Preferably, a diagonal brace 8 is provided at the corner of the L-shaped guide rod 501.

[0039] By setting the diagonal brace 8, the overall structural strength of the L-shaped guide rod 501 can be enhanced, preventing it from deforming under stress.

[0040] Preferably, the two ends of the L-shaped guide rod 501 are connected to the support plate 4 and the lifting plate 502 by welding, respectively.

[0041] This ensures the reliability of the connection between the L-shaped guide rod 501, the support plate 4, and the lifting plate 502, and improves their service life.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
