Abstract
Description
Technical Field
[0001] This utility model relates to the field of expansion joint reinforcement structure technology, and in particular to an adjustable aluminum template expansion joint adaptation reinforcement structure. Background Technology
[0002] Expansion joints are structural joints installed in building construction to accommodate deformations caused by factors such as temperature changes, uneven foundation settlement, and earthquakes. This prevents cracks and damage, ensuring the building's safety and stability. Functionally, they can be categorized into expansion joints, settlement joints, and seismic joints. Expansion joints primarily prevent cracking due to thermal expansion and contraction. They are typically installed horizontally in long buildings, dividing the building into units. The joint width is usually 20-30 mm, and it is filled with deformable sealing material. Settlement joints, on the other hand, prevent damage to different parts of the building due to uneven foundation settlement. They are installed where there are significant differences in building height, structural form, foundation depth, or soil compressibility. They completely separate the building from the foundation to the roof. The joint width depends on the foundation conditions and building height, generally ranging from 30-70 mm. Seismic joints are designed to improve the earthquake resistance of buildings. In earthquake-prone areas, they are installed when a building has a complex floor plan, significant height differences, or changes in structural type. They divide the building into relatively independent units, reducing damage caused by collisions between different parts under seismic forces. The joint width is generally 50-100 mm, with the specific value determined based on the seismic fortification intensity and building height.
[0003] Expansion joints in aluminum formwork are special structures installed in building structures using aluminum formwork. Aluminum formwork is widely used in construction due to its high strength, light weight, and reusability. The presence of expansion joints is crucial for accommodating deformations caused by factors such as temperature changes, foundation settlement, and earthquakes. They are typically composed of specific aluminum alloy profiles and matching rubber strips. The aluminum alloy profiles possess good strength and corrosion resistance, ensuring structural stability, while the rubber strips are elastic and effectively absorb deformation energy, preventing structural damage caused by deformation.
[0004] However, some existing aluminum formwork cannot achieve a tight fit and effective adaptation when facing expansion joints of different widths and forms. This not only makes it difficult to guarantee the construction quality at the expansion joint, but also easily leads to problems such as grout leakage and misalignment, which in turn affects the overall appearance and waterproof performance of the building. Furthermore, the inability to effectively absorb and buffer the stress generated by structural deformation poses a potential threat to the stability and durability of the building structure. Therefore, in order to address the above shortcomings, an adjustable aluminum formwork expansion joint adaptation and reinforcement structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides an adjustable aluminum formwork expansion joint adaptation and reinforcement structure, which aims to improve the problem that some aluminum formworks in the prior art cannot achieve adaptation and effective adjustment to expansion joints.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An adjustable aluminum formwork expansion joint adaptation and reinforcement structure includes a right wall and a left wall. Aluminum formwork is installed at the top of both the right and left walls. Positioning components are installed at the top of the two aluminum formworks. Two connecting plates are fixedly connected to adjacent sides of the two aluminum formworks. Elastic elements are fixedly connected to adjacent sides of multiple connecting plates. Connecting plates are fixedly connected to the front and rear sides of multiple elastic elements. Two sliding rods are slidably connected to both aluminum formworks. Limiting plates are fixedly connected to the left and right sides of multiple sliding rods. Springs are sleeved on the outer left and right sides of multiple sliding rods. Multiple limiting grooves are opened inside both aluminum formworks.
[0008] Through the above technical solution: when the wall is displaced due to deformation, the aluminum formwork can slide within a certain range through the sliding rod. The spring on the sliding rod can provide elastic buffering and limit the sliding range of the sliding rod. The elastic element can also deform under the connection of connecting plate one and connecting plate two, further buffering the displacement of the wall. Through the positioning components and limiting grooves, the deformation joint can be adapted and reinforced, thereby enhancing the stability and adaptability of the structure.
[0009] As a further description of the above technical solution:
[0010] The positioning component includes a cover, the bottom of which is disposed on top of the two aluminum templates, and the cover is internally threaded with a plurality of fastening bolts;
[0011] The above technical solution involves using rotating fastening bolts to firmly fix the cover onto the aluminum template, thereby positioning the aluminum template and effectively preventing displacement at the top, thus ensuring the stability of the entire adjustable aluminum template expansion joint reinforcement structure.
[0012] As a further description of the above technical solution:
[0013] Both aluminum templates are fixedly connected to a waterproof board at their bottom, the bottom of the cover is fixedly connected to two sealing strips, the left side of the right wall is fixedly connected to an extrusion plate, and the bottom of the extrusion plate is fixedly connected to a foam board.
[0014] Through the above technical solution: when water seeps into the bottom of the aluminum formwork, the waterproof membrane can prevent the water from seeping further down, thus achieving a waterproof effect. The two sealing strips fixed at the bottom of the cover will tightly adhere to the surface of the aluminum formwork after the cover is installed on top. During movement, as the cover's position is fixed, the sealing strips maintain a continuous seal, effectively preventing external moisture, dust, and other impurities from entering through the connection between the cover and the aluminum formwork.
[0015] As a further description of the above technical solution:
[0016] The limiting disc is externally slidably connected to the inside of the limiting groove, and the slide rod is externally slidably connected to the inside of the connecting plate 2;
[0017] Through the above technical solution: when the elastic element deforms due to the displacement of the wall, the connecting plate 2 moves accordingly, and the slide rod slides smoothly inside it. With the expansion and contraction of the elastic element, the aluminum template is guaranteed to adapt to displacement within a certain range, so that the entire structure can flexibly cope with the deformation of the wall and maintain the reinforcement effect.
[0018] As a further description of the above technical solution:
[0019] One end of the spring is fixedly connected to the inside of the aluminum template, and the other end of the spring is fixedly connected to the outside of the limiting plate;
[0020] Through the above technical solution: when the aluminum formwork moves due to the displacement of the wall, it drives the sliding rod and the limiting plate to move synchronously, and the spring will extend and retract according to the relative displacement of the aluminum formwork and the limiting plate.
[0021] As a further description of the above technical solution:
[0022] Both the front and rear sides of the elastic element are arc-shaped, and the external thread of the fastening bolt is connected to the inside of the aluminum template.
[0023] Through the above technical solution: the elastic component will deform due to the displacement of the aluminum template. Its arc structure can better adapt to the force in different directions. Compared with the straight structure, the arc design makes the elastic component more uniformly stressed during the deformation process. It can absorb and buffer the stress brought by the displacement of the wall through its own elastic deformation, effectively avoiding structural damage caused by stress concentration.
[0024] As a further description of the above technical solution:
[0025] Both the right wall and the left wall have sealing grooves inside, and the sealing strip is slidably connected to the inside of the sealing groove.
[0026] Through the above technical solution, the sealing strip prevents external water, air, dust and other impurities from entering the interior of the wall through the gaps, achieving waterproof, dustproof and soundproof effects, and improving the overall performance and durability of the building.
[0027] As a further description of the above technical solution:
[0028] The elastic element is made of spring steel, the extrusion plate is made of hard rubber, and the foam board is made of polyurethane.
[0029] The above technical solution works as follows: when the right wall shifts, the extrusion plate moves with it and comes into contact with the left wall for compression. The hard rubber has a certain hardness to transmit the extrusion force and is also elastic, which can disperse the pressure during the compression process and avoid damage to the wall due to concentrated stress. At the same time, it can also adapt to a certain degree of wall deformation. The foam board is made of polyurethane and is installed at the bottom of the extrusion plate. During the compression process of the relative movement of the wall, the polyurethane foam board is soft and porous, which can further absorb the extrusion energy and play a role in buffering and shock absorption.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, when the building deformation causes the right wall and left wall to shift, the elastic element deforms, driving the second connecting plate to move. The sliding rod slides within the second connecting plate, and at the same time, the spring compresses or stretches according to the displacement of the sliding rod, providing a reverse force to the sliding rod, thereby realizing the dynamic adjustment of the deformation joint. This allows the entire structure to adapt well to the building deformation, ensuring the safety of the building structure and ensuring the stability and reliability of the entire adjustment process. It further enhances the adaptability of the structure to building deformation.
[0032] 2. In this utility model, the bottom of the waterproof board fits tightly with the sealing groove inside the wall to form an effective waterproof barrier, effectively preventing rainwater or other liquids from seeping into the building through the expansion joint. This plays a key role in ensuring the waterproof performance of the building. The sealing strip fits tightly with the sealing groove inside the wall, further enhancing the waterproof sealing effect of the expansion joint and preventing water from seeping in from the top. Together with the waterproof board, it comprehensively protects the waterproof performance of the building. Attached Figure Description

[0039] 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.
[0040] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides an adjustable aluminum formwork expansion joint adaptation and reinforcement structure, including a right wall 1 and a left wall 2. The left wall 2 and the right wall 1 together form the support structure on both sides of the expansion joint in the building. Aluminum formwork 3 is provided on the top of both the right wall 1 and the left wall 2. The aluminum formwork 3 is installed on the top of the right wall 1 and the left wall 2. A positioning component is provided on the top of the two aluminum formwork 3. The positioning component includes a cover 4. The bottom of the cover 4 is set on the top of the two aluminum formwork 3. The shape and size of the cover 4 are designed according to the structure of the top of the aluminum formwork 3. It can completely cover the connection part of the top of the aluminum formwork 3, and play a protective and decorative role. Multiple fastening bolts 5 are connected to the internal thread of the cover 4. The external thread of the fastening bolts 5 is connected to the inside of the aluminum formwork 3. Two connecting plates 6 are fixedly connected to the adjacent side of the two aluminum formwork 3. Elastic elements 7 are fixedly connected to the adjacent side of the multiple connecting plates 6. The connecting plates 6 play the role of a bridge connecting the aluminum formwork 3 and the elastic elements 7.
[0041] The elastic element 7 has an arc-shaped design on both its front and rear sides. This arc design can better adapt to the displacement in different directions that may occur during building deformation. The elastic element 7 is made of spring steel. When the building deforms due to external factors and the right wall 1 and left wall 2 experience relative displacement, the elastic element 7 can absorb and buffer part of the deformation force through its own elastic deformation. Connecting plates 2 8 are fixedly connected to the front and rear sides of multiple elastic elements 7. Two sliding rods 9 are slidably connected to the two aluminum templates 3. The external parts of the sliding rods 9 are slidably connected to the inside of the connecting plates 2 8. Limiting discs 10 are fixedly connected to the left and right sides of multiple sliding rods 9. The limiting discs 10 limit the sliding range of the sliding rods 9 and also cooperate with the springs 11 to achieve elastic constraint on the sliding rods 9. Springs 11 are fitted on the external left and right sides of multiple sliding rods 9. One end of the spring 11 is fixedly connected to the inside of the aluminum template 3, and the other end of the spring 11 is fixed... The limiting plate 10 is fixedly connected to the outside of the limiting plate 10. When the building deforms and the sliding rod 9 slides in the connecting plate 2 8, the spring 11 will compress or stretch according to the displacement of the sliding rod 9. With the help of the elastic force of the spring 11, a reverse force is provided to the sliding rod 9, so that the structure can maintain a certain elastic recovery force during the deformation process and better adapt to the deformation of the building. Multiple limiting grooves 12 are opened inside the two aluminum templates 3. The outside of the limiting plate 10 is slidably connected to the inside of the limiting groove 12. The limiting groove 12 is used to limit the sliding range of the limiting plate 10.
[0042] Reference Figures 1 to 2 Both aluminum formwork 3 have waterproof boards 13 fixedly connected to their bottoms. The bottom of the waterproof boards 13 can fit tightly with the sealing groove inside the wall, forming an effective waterproof barrier to prevent rainwater or other liquids from seeping into the building through the expansion joint, thus ensuring the building's waterproof performance. The bottom of the cover 4 has two sealing strips 14 fixedly connected. Sealing grooves are provided inside both the right wall 1 and the left wall 2. The outer surface of the sealing strips 14 slides inside the sealing grooves. When the cover 4 is installed on top of the aluminum formwork 3, the sealing strips 14 can fit tightly with the sealing groove inside the wall, further enhancing the waterproof sealing effect of the expansion joint and preventing water penetration. The left side of the right wall 1... A compression plate 15 is fixedly connected. The compression plate 15 is made of hard rubber. Hard rubber has a certain degree of hardness and elasticity, and can deform to a certain extent when subjected to greater pressure, thereby absorbing and buffering the impact force generated by building deformation. A foam board 16 is fixedly connected to the bottom of the compression plate 15. The foam board 16 is made of polyurethane. When the building deforms, when the compression plate 15 comes into contact with structural components such as the left wall 2 and is squeezed, the foam board 16 can be further compressed and deformed, absorbing more energy and enhancing the buffering effect. This comprehensively ensures the stable operation of the adjustable aluminum formwork expansion joint adaptation and reinforcement structure during building deformation.
[0043] Working principle: When the building deforms due to external factors, i.e., the right wall 1 and the left wall 2 undergo relative displacement, the elastic design of the spring steel of the elastic element 7, in conjunction with the sliding of the slide rod 9 within the connecting plate 8, and the elastic force of the spring 11, enables the adaptation and adjustment of the expansion joint to accommodate the building's deformation. In terms of sealing and buffering, the waterproof plate 13 at the bottom of the aluminum formwork 3 and the sealing strip 14 at the bottom of the cover 4 can respectively cooperate with the sealing groove inside the wall to achieve waterproof sealing. The extrusion plate 15 on the left side of the right wall 1, due to its hard rubber material, has a certain buffering performance, and the polyurethane foam board 16 at the bottom can also assist in buffering. Together, they achieve effective buffering, comprehensively ensuring the stable operation of the adjustable aluminum formwork expansion joint adaptation and reinforcement structure during building deformation, ensuring the safety of the building structure and good waterproof performance.
