Description

TECHNICAL FIELD

[0001] The utility model relates to prefabricated building technical field, concretely relates to a wall connecting piece suitable for prefabricated building. BACKGROUND

[0002] In the vigorous development process of modern construction industry, prefabricated building gradually becomes an important development direction in the field of construction with its unique advantages. Prefabricated building is prefabricated in the factory, then transported to the construction site for assembly. This construction mode greatly improves the construction speed, effectively shortens the project period, better controls the building quality, reduces the environmental pollution of the construction site, meets the needs of energy saving and environmental protection, and therefore is more and more widely used.

[0003] Among the many key technical links of prefabricated building, the connection technology between walls is crucial, which directly relates to the stability, safety and use function of the whole building. However, the existing wall connecting pieces on the market have many problems that cannot be ignored, which seriously restricts the further development and promotion of prefabricated building.

[0004] Firstly, the traditional wall connecting piece mostly adopts simple bolt connection or welding method. Bolt connection faces many challenges in actual use. Because the building will be affected by various factors in the long-term use process, such as slight vibration, temperature change, etc. These factors will cause the bolt to gradually loosen. Once the bolt is loose, the stability of the wall connection will be greatly reduced, which will affect the reliability of the building structure. Moreover, the loose bolt will rub and collide with other parts of the connecting piece when the wind blows or the temperature changes, producing loud noise, which seriously affects the living comfort of the residents. Although the welding method can ensure the connection strength to a certain extent, it requires high technical level of the construction personnel. The high temperature generated in the welding process may damage the wall material and change the physical and chemical properties of the wall material, thereby affecting the overall performance of the wall. In addition, the detection and control of welding quality is difficult, and it is difficult to accurately evaluate whether the quality of the welded part meets the standard, which also poses a hidden danger to the safety of the building structure.

[0005] In addition, the existing connectors generally lack effective waterproof design. Due to construction errors, material shrinkage, and other reasons, gaps will inevitably appear at the spliced joints of the wall. Rainwater can easily penetrate through these gaps into the building, causing a series of problems. The penetration of rainwater can cause the wall to mildew, not only affecting the appearance of the wall, but also breeding bacteria, endangering the health of the occupants; the decorative layer will gradually fall off after being eroded by rainwater for a long time, affecting the indoor and outdoor decoration effect of the building; more seriously, long-term penetration of rainwater can erode the building structure, reducing the durability of the building structure and threatening the overall safety of the building. Especially in some rainy areas or high-rise buildings, the waterproofing problem is more prominent and the harm to the building is greater.

[0006] With the continuous improvement of people's living standards, the demand for building functions is increasingly diversified and refined. Single connection function has long been unable to meet the requirements of modern buildings. The sound insulation and thermal insulation performance of buildings are crucial to the comfort of the indoor environment. However, the existing connectors rarely consider these factors, cannot improve the overall performance of the building while connecting the wall, and cannot meet people's demand for high-quality buildings.

[0007] During the construction process of prefabricated buildings, construction convenience is a key issue. Some complex connectors have a cumbersome installation process that requires professional construction equipment and technical personnel to operate, which not only increases construction time and cost, but also reduces construction efficiency. For large prefabricated building projects, improving construction efficiency can bring significant economic and social benefits. The extension of construction time means an increase in project costs, including labor costs, equipment rental costs, etc.; at the same time, it will also affect the delivery time of the project and reduce the market competitiveness of the enterprise. Therefore, the deficiencies of the existing connectors in terms of construction convenience need to be addressed.

[0008] In summary, the existing prefabricated building wall connectors have many problems that seriously affect the development and application effect of prefabricated buildings. Developing a new type of wall connector that can overcome these problems has become an important issue in the current construction field. Practical new type content

[0009] The present utility model aims to solve the various problems existing in the existing prefabricated building wall connectors. For example, the connection stability is insufficient, the bolts are prone to looseness, and the welding quality is difficult to control; the waterproof design is lacking, rainwater is easy to penetrate; the function is single, and it cannot meet the demand for sound insulation and thermal insulation; the construction convenience is poor, and the installation is complex and time-consuming. It strives to provide a multifunctional connector to improve the performance of the building and the construction efficiency.

[0011] A connecting component comprising:

[0012] A central connecting body in a rectangular block structure, wherein two opposite sides of the rectangular block structure are respectively provided with a slot, and the bottom of the slot is provided with an elastic buffer pad;

[0020] ​The utility model focuses on a series of problems existing in the assembled building wall connecting piece. The traditional wall connecting piece is poor in stability, and is easy to be loosened by building vibration and temperature change, and the loosening reduces the connection stability and produces noise, and welding requires high technical requirements for construction personnel, and quality detection and control are difficult. In terms of waterproof, the existing connecting piece lacks effective waterproof design, and the wall splicing gap is easy to let rainwater penetrate, and causes wall mildew, decorative layer falling off and other conditions, and affects the durability of building structure. Moreover, its function is single, and it is difficult to meet the demand of modern building on sound insulation, heat preservation and other functions. In addition, the complex installation process increases the construction time and cost, and reduces the construction efficiency. The utility model is dedicated to overcoming these problems, and creating a multifunctional wall connecting piece, improving the connection stability, waterproofness, increasing the functional diversity, improving the construction convenience, and promoting the better development of the assembled building.

[0021] According to one aspect of the present application, a wall connecting piece suitable for assembled building is provided, comprising:

[0022] The connecting part comprises:

[0023] The central connecting body is a rectangular block structure, wherein two opposite sides of the rectangular block structure are respectively provided with a slot, and the bottom of the slot is provided with an elastic buffer pad;

[0024] Four connecting arms, one end of each of the four connecting arms is inserted into one slot of the connecting body and in contact with the elastic buffer pad, and the other end extends outward from the central connecting body and is provided with a mounting plate, and the mounting plate is provided with a plurality of mounting holes;

[0025] A polytetrafluoroethylene layer covers the entire connecting part.

[0026] Figure 1 A top perspective view of the wall connecting piece 100 according to one embodiment of the utility model is shown. Figure 2 A planar perspective view of the connecting part 1 covered by the polytetrafluoroethylene layer in the wall connecting piece 100 according to one embodiment of the utility model is shown. Figure 3 A cross-sectional view of the connecting part 1 along the line L shown in FIG. Figure 2

[0027] ​Specifically, the wall connecting piece 100 comprises a connecting component 1, which comprises a center connecting body 2 in a rectangular block structure, wherein two opposite sides of the rectangular block structure are respectively provided with a slot 3, and the bottom of the slot 3 is provided with an elastic buffer pad 4; four connecting arms 5, one end of each of the four connecting arms 5 is inserted into one slot 3 of the connecting body 2 and in contact with the elastic buffer pad 4, and the other end extends outward from the center connecting body 2 and is provided with a mounting plate 6 provided with a plurality of mounting holes 7; and a polytetrafluoroethylene layer 8 covering the entire connecting component 2.

[0028] As shown in Figure 2 In the plane direction of the wall connecting piece 100, A, B, C and D are divided into four areas by the dotted lines L1 and L2 perpendicular to each other. When the wall connecting piece is applied to connect the walls, the above-mentioned A, B, C and D are respectively fixedly connected with four walls through the mounting holes 7.

[0029] The wall connecting piece of the utility model mainly comprises a connecting component and a polytetrafluoroethylene layer covering the outside of the connecting component. The connecting component comprises a center connecting body and four connecting arms, and each part cooperates to play a key role.

[0030] The center connecting body is in a rectangular block structure, which facilitates cooperation with the connecting arms and other building components while ensuring structural stability. The four opposite sides are each provided with a slot, and the bottom of the slot is provided with an elastic buffer pad. The slot provides precise positioning for the installation of the connecting arm, ensuring the accuracy of the connection; the elastic buffer pad is a key link for improving the stability of the connection, which can effectively cope with adverse factors such as vibration and temperature change during building use, prevent the connection from loosening and reduce noise.

[0031] The four connecting arms are respectively inserted into the slots of the center connecting body, one end is in close contact with the elastic buffer pad, and the other end extends out and is provided with a mounting plate. The mounting plate is provided with a plurality of mounting holes for fixedly connecting with the walls. This multi-arm connecting structure greatly enhances the connection strength between the connecting piece and the walls, disperses the force between the walls, so that the connecting piece can better withstand forces in different directions, and the stability is significantly improved compared with the traditional connecting method.

[0032] The polytetrafluoroethylene layer fully covers the entire connecting component, and with its excellent water resistance, corrosion resistance, low friction coefficient, chemical stability and thermal stability, etc. characteristics, not only effectively solves the waterproof problem, but also brings additional functional advantages to the connecting piece, and improves the overall performance of the building.

[0033] According to certain preferred embodiments of the present application, the rectangular block structure of the center connecting body is carefully planned in size, with a length range of 20-50 cm, a width range of 10-30 cm, and a height range of 5-15 cm. This size interval takes into account various factors to ensure that the connecting piece is applicable in different scale prefabricated building projects. Smaller size is suitable for small buildings or indoor partition wall connection, facilitating installation and saving materials; larger size meets the requirements of higher connection strength and stability in large buildings, high-rise residences and other scenarios, ensuring firm and reliable wall connection.

[0034] Preferably, the slot is provided on the four sides of the center connecting body, and its depth is closely related to the length of the insertion end of the connecting arm. Reasonable slot depth can ensure stable and reliable insertion of the connecting arm, avoiding the risk of shaking or falling off. The inner wall of the slot is provided with anti-skid lines, which further enhances the friction between the connecting arm and the center connecting body, preventing displacement of the connecting arm during use. Even when the building is subjected to a large external force, it can maintain a good connection state and improve the overall structural stability.

[0035] Preferably, the elastic buffer pad is made of ethylene propylene diene rubber material, which has excellent weather resistance, chemical corrosion resistance and elasticity. In daily use of buildings, it can play a good buffering role in the face of vibration, temperature change and other situations. For example, when the building slightly shakes due to wind, the elastic buffer pad can absorb vibration energy to avoid rigid collision between connecting parts and prevent connection from loosening; when the material expands and contracts due to temperature changes, the buffer pad can provide a certain expansion space to reduce the problem of bolt loosening caused by stress concentration, thereby effectively reducing the noise generated by wind or temperature changes and improving the comfort of living. Some elastic buffer pads are provided with a honeycomb shock-absorbing structure, which further optimizes the shock-absorbing effect. The honeycomb hole design increases the elastic deformation capacity of the buffer pad, which can more efficiently absorb and disperse vibration energy to ensure connection stability. The thickness of the elastic buffer pad is controlled between 0.5-2 cm, which ensures sufficient buffering performance without affecting the overall structural compactness of the connecting piece. Optionally, some elastic buffer pads are embedded with metal spring sheets, which enhance the compression resistance of the buffer pad, allowing it to maintain good elasticity even under high pressure, effectively extending the service life of the buffer pad and ensuring long-term stable connection effect. In addition, the compression resilience rate of the elastic buffer pad is greater than 80%, which means that after being compressed by external force, it can quickly recover to its original state and continuously exert its buffering effect, ensuring that the connecting piece is always in good working condition.

[0036] According to certain preferred embodiments of the present application, the length of the connecting arm is in the range of 30-80 cm, which takes into account the spacing between different walls and the requirements of the building structure. Shorter connecting arms are suitable for smaller wall spacing, are convenient to install and have lower cost. Longer connecting arms can meet the connection requirements of larger wall spacing in large buildings, ensuring stable wall connection. The cross-sectional shape of the connecting arm is rectangular, and the length ratio of the long side to the short side is controlled between 2:1 and 3:1. This rectangular cross-sectional design ensures the strength of the connecting arm while taking into account the material usage efficiency and processing convenience. Compared with circular or other shapes, the rectangular cross-section can better resist bending and torsional forces, making the connecting arm more stable and reliable when transmitting the inter-wall forces.

[0037] Preferably, reinforcing ribs are provided at the connection between the connecting arm and the mounting plate, and the number of reinforcing ribs is 2-4, and the height is 0.3-0.5 times the thickness of the connecting arm. The presence of reinforcing ribs significantly enhances the connection strength between the connecting arm and the mounting plate, effectively disperses the stress concentration at the connection, avoids the problem of fracture or deformation during long-term stress, and ensures the overall structural integrity and stability of the connecting piece.

[0038] Preferably, a limiting protrusion is provided at one end of the connecting arm inserted into the slot, and a limiting groove is provided at the corresponding position of the slot. This limiting design precisely limits the insertion depth and position of the connecting arm, preventing excessive insertion or disengagement of the connecting arm, and ensuring the accuracy and reliability of the connection. During installation, the limiting structure facilitates quick and accurate connection operations for construction personnel, improving construction efficiency; during use, it effectively prevents displacement of the connecting arm due to external forces, ensuring the stability of the wall connection.

[0039] According to certain preferred embodiments of the present application, the length of the mounting plate is in the range of 15-30 cm, and the width is in the range of 10-20 cm, which ensures that the mounting plate can be well adapted to common wall materials and is convenient for construction personnel to operate. The mounting holes on the mounting plate are circular, with a diameter in the range of 8-12 mm and a number of 2-8. The circular mounting holes facilitate the use of standard bolts or screws for fixed connection, ensuring the connection strength; the reasonable hole diameter and number setting can meet the different wall fixing requirements and ensure that the mounting plate is evenly stressed during fixing, avoiding the problem of local stress being too large, which causes the mounting plate to deform or the wall to be damaged.

[0040] Preferably, a sealing strip mounting groove is arranged on the mounting plate and surrounds the mounting hole. The sealing strip mounting groove has a depth of 0.3-0.5 cm and is used to mount a sealing strip. The sealing strip is made of silicone rubber and has good waterproof and sealing properties. During installation, the sealing strip fills the gap between the mounting hole and the bolt or screw, effectively preventing liquid such as rainwater from penetrating, improving the waterproof performance of the connecting piece, and avoiding problems such as mold growth and decorative layer peeling caused by rainwater leakage, thereby prolonging the service life of the building. The edge of the mounting plate is provided with a pre-positioning protrusion, which can be aligned with the wall embedded part during installation, providing accurate positioning for installation, facilitating quick and accurate installation of the connecting piece by construction personnel, improving construction efficiency, and reducing installation errors. Stress dispersion grooves are provided around the mounting hole, which can effectively disperse the stress concentration generated by the mounting hole when subjected to external forces, avoid cracks or damage around the mounting hole, and improve the overall strength and reliability of the mounting plate and connecting piece.

[0041] Optionally, the back of the mounting plate is provided with a magnetic adsorption layer, which can be adsorbed on the metal embedded part or other magnetic materials of the wall during construction, achieving temporary fixation of the connecting piece. This design facilitates the adjustment of the position of the connecting piece by construction personnel during installation, reduces the operational burden of construction personnel, improves construction convenience, and effectively reduces construction difficulty and safety risk, especially in high-altitude operations or complex construction environments.

[0042] According to certain preferred embodiments of the present application, the polytetrafluoroethylene layer fully covers the entire connecting component, forming an efficient waterproof barrier. Polytetrafluoroethylene has excellent waterproof performance and can effectively prevent rainwater from penetrating into the building through the gap at the wall joint. This feature is particularly important in rainy areas or high-rise buildings, as it can prevent rainwater from eroding and damaging the wall connecting piece and wall structure, avoid problems such as mold growth and decorative layer peeling, and significantly improve the durability and safety of the building structure.

[0043] Preferably, the polytetrafluoroethylene layer not only has a waterproof function, but also has low friction coefficient, good chemical stability and thermal stability, etc. The low friction coefficient allows the wall to slide smoothly between the connecting piece and the wall when there is a slight displacement due to temperature changes, reducing wear and tear and prolonging the service life of the connecting piece; good chemical stability can effectively prevent the connecting piece from being corroded, even in harsh chemical environments, the performance remains stable; thermal stability helps the connecting piece to work normally in different temperature environments, ensuring that the overall performance of the building is not affected by temperature fluctuations, and improving the adaptability of the building.

[0044] Preferably, the polytetrafluoroethylene layer has a thickness of 1-5 mm, which can ensure the functions of the polytetrafluoroethylene layer and will not affect the overall structural performance of the connecting piece due to excessive thickness. In terms of construction, the surface of the connecting component is sandblasted before being coated with the polytetrafluoroethylene layer. The sandblasting treatment can roughen the surface of the connecting component, increase the adhesion between the polytetrafluoroethylene layer and the connecting component, and ensure that the polytetrafluoroethylene layer is firmly attached to the surface of the connecting component and is not easily detached, thereby ensuring long-term stable protection effect. The surface of the polytetrafluoroethylene layer has a positioning portion at a position corresponding to the mounting hole on the mounting plate. The positioning portion is a positioning hole that penetrates from one surface of the mounting plate to the other surface of the mounting plate through the mounting hole. During installation, the installer can quickly and accurately find the position of the mounting hole through the positioning hole, which facilitates bolt or screw installation operation, improves construction efficiency, and reduces installation errors.

[0045] The elastic buffer pad and the multi-arm connecting structure cooperate to effectively solve the problem of insufficient stability of the traditional connecting piece. The elastic buffer pad plays an excellent buffering and stress adjusting role when responding to building vibration and temperature changes, preventing connection loosening and noise generation. The multi-arm connecting mode in which four connecting arms are inserted into the center connection main body slot disperses the force between the walls, improves the overall connection strength and stability, makes the wall connection more firm and reliable, and ensures the safety of the building structure.

[0046] In addition, the overall coating of the polytetrafluoroethylene layer provides excellent waterproof performance for the connecting piece, effectively prevents rainwater penetration, and solves the problem of insufficient waterproof performance of the existing connecting piece. In combination with the sealing strip on the mounting plate, the waterproof effect is further enhanced to avoid the erosion of rainwater on the wall and the building structure, reduce the problems such as mold on the wall surface and peeling of the decorative layer, prolong the service life of the building, and improve the quality of the building. The various excellent properties of the polytetrafluoroethylene layer bring additional functions to the connecting piece, such as low friction coefficient to reduce wear, chemical stability to prevent corrosion, and thermal stability to adapt to different temperature environments, thereby improving the overall performance of the building. At the same time, the structure design of the connecting piece provides convenience for adding soundproofing and heat preservation functional modules. Glass wool and other soundproofing materials can be added between the connecting component and the polytetrafluoroethylene layer to meet the demand of the building for soundproofing and heat preservation functions, realize functional diversification, and improve the living comfort.

[0047] Preferably, the design of multiple mounting holes on the mounting plate allows the installer to quickly fix the connecting piece on the wall through simple operation without the need for complex technology and equipment, thereby reducing the construction difficulty. The pre-positioning protrusions, magnetic adsorption layer of the mounting plate, and positioning holes on the polytetrafluoroethylene layer further improve the construction efficiency, reduce the construction time and cost, and are especially suitable for large prefabricated building projects, thereby improving the economic benefits and market competitiveness of the enterprise.
