Description

Technical Field

[0001] This utility model relates to the field of prefabricated fiber concrete exterior wall panels, specifically to a lightweight prefabricated fiber concrete exterior wall panel. Background Technology

[0002] Currently, the exterior wall panel market is showing a diversified trend, with various materials, specifications and styles of exterior wall panels emerging one after another. Among them, fiber concrete exterior wall panels are gradually gaining market favor due to their advantages such as lightweight and high strength, convenient construction and environmental protection and energy saving.

[0003] The lightweight, prefabricated fiber-reinforced concrete exterior wall panels utilize advanced fiber-reinforced concrete materials. Through factory prefabrication and on-site assembly, the construction cycle is significantly shortened, and construction efficiency is improved. These wall panels not only possess excellent physical properties and decorative effects but also meet the requirements of modern architecture for lightweighting, high strength, and energy conservation and environmental protection.

[0004] However, despite the numerous advantages of lightweight prefabricated fiber-reinforced concrete exterior wall panels in the market, some problems still exist. For example, exterior wall panels are typically flat and made of lightweight concrete materials. While these materials ensure a certain level of strength, their load-bearing capacity is relatively low, affecting the load-bearing capacity of the exterior wall panels. Directly increasing the thickness of the exterior wall panels would increase their self-weight, leading to increased material costs, as well as affecting transportation and installation costs. Utility Model Content

[0005] The present invention aims to provide a lightweight and thin prefabricated fiber concrete exterior wall panel to solve the problem of low load-bearing capacity of current exterior wall panels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight prefabricated fiber concrete external wall panel, comprising: a wall panel, ribs, and connectors, wherein the ribs are fixedly connected to the wall panel, the ribs are evenly distributed on the wall panel, the ribs are located at the inner surface end of the wall panel, the wall panel and the ribs are both made of fiber concrete and steel bars, the connectors are fixed to the wall panel, and the connectors are used to connect the wall panel and the building's support system.

[0007] The principle of this scheme is as follows: First, a model is made in the prefabrication plant using PVC or steel plates, the reinforcing bars are tied, the connectors are placed in the corresponding positions of the model, and fiber-reinforced concrete is poured into the model to complete the fabrication of the wall panels, ribs, and connectors; then, at the installation site, the external wall panels are installed onto the building's support system using the connectors to complete the installation of the external wall panels, and the ribs are connected to the building's support system.

[0008] Advantages of this solution: By adding ribs to the wall panels, the rigidity of the wall panels can be increased, effectively enhancing their bending resistance; the ribs also increase the shear strength of the wall panels; the hollow design of the ribs reduces the density and weight of the panels by creating hollow areas, without affecting their structural strength; this prefabricated wall panel and rib design facilitates rapid installation of the external wall panels, greatly improving construction speed; the connectors facilitate the installation of the external wall panels onto the building's support system, reducing construction difficulty; and the steel reinforcement further strengthens the sleeve structure, while increasing the contact area between the sleeve and the fiber-reinforced concrete, thus increasing the connection stability between the sleeve and the wall panel.

[0009] Furthermore, the wall panel and ribs are integrally formed, and the wall panel and ribs are double-T shaped. The T-shaped structure generally offers a better balance between weight and size, making transportation and hoisting more convenient. At the same time, due to its unique structure, the T-shaped wall panel can reduce overall weight while maintaining the strength and stability of the wall panel.

[0010] Furthermore, the sleeve is perpendicular to the wall panel.

[0011] Furthermore, the outer wall of the sleeve is provided with burrs. The burrs can increase the contact area between the sleeve and the concrete, which can help the sleeve to evenly distribute the external load in the concrete, thus helping to improve the load-bearing capacity of the object and thereby increase the load-bearing capacity of the object. The burrs can be effectively embedded in the concrete surface, enhancing the adhesion between the sleeve and the concrete and reducing the possibility of the sleeve slipping or loosening.

[0012] Furthermore, the reinforcing bars in the screw sleeve are fixedly connected to the reinforcing bars in the wall panel. This further increases the connection stability between the sleeve and the wall panel.

[0013] Furthermore, the length of the sleeve is greater than the thickness of the wall panel, which facilitates the installation of screws.

[0014] Furthermore, multiple screw sleeves are provided, and the screw sleeves are evenly distributed on the wall panel. The provision of multiple screw sleeves enhances the connection stability between the wall panel and the building's support system.

[0015] Furthermore, the steel bars in the plate ribs are arranged at an angle. By arranging the steel bars at an angle, the plate ribs can distribute the bending moment and shear force more evenly, thereby improving the stability of the entire structure and reducing the risk of local plastic deformation and failure.

[0016] Furthermore, the outer surface of the wall panel is provided with a water guiding groove, which improves the waterproof performance and durability of the wall panel.

[0017] Furthermore, the water guide channel is herringbone shaped. The V-shaped cross-section of the herringbone water guide channel can effectively guide the water flow to the bottom of the channel and flow along the channel surface. The flow of water in the channel is not easily obstructed, which can reduce water accumulation. At the same time, since the water flow can naturally carry away debris, it reduces the accumulation in the channel and reduces the frequency and cost of cleaning and maintenance. The shape of the herringbone water guide channel gives the channel wall strong compressive strength, especially when subjected to external loads (such as water accumulation, snow weight, etc.), it can effectively disperse pressure and reduce the deformation or cracking of the channel body.

[0019] Figure 2 This is an embodiment of the present utility model. Figure 1 A cross-sectional view along the AA direction. Detailed Implementation

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: wall panel 1, panel rib 2, sleeve 3, and panel connecting strip 4.

[0022] Example:

[0023] A lightweight, prefabricated fiber-reinforced concrete exterior wall panel, as shown in the attached... Figure 1 and attached Figure 2 As shown, the structure includes: wall panel 1, ribs 2, and connectors. Ribs 2 are fixedly connected to wall panel 1 and are evenly distributed on wall panel 1, located at the inner surface end of wall panel 1. By setting ribs 2 on wall panel 1, the stiffness of wall panel 1 can be increased, effectively enhancing its bending resistance; ribs 2 can increase the shear strength of wall panel 1, especially when encountering lateral forces (such as wind force and earthquake force), ribs 2 can help wall panel 1 more effectively transfer shear force, thereby improving its shear resistance; the hollow design of ribs 2 reduces the density and weight of the panel by forming hollow areas, without affecting its structural strength.

[0024] Both wall panel 1 and rib 2 are made of fiber reinforced concrete and steel bars. Specifically, wall panel 1 and rib 2 use concrete with a concrete grade of C60 or higher. In this embodiment, existing concrete is used, and the concrete mix ratio is not adjusted in this scheme.

[0025] The outer surface of wall panel 1 is provided with a water guiding channel (not shown in the figure). By setting the water guiding channel, the waterproof performance and durability of wall panel 1 are improved. The water guiding channel is herringbone shaped. The V-shaped cross-section of the herringbone water guiding channel can effectively guide the water flow to the bottom of the channel and flow along the channel surface. The flow of water in the channel is not easily obstructed, which can reduce water accumulation. At the same time, since the water flow can naturally carry away debris, it reduces the accumulation in the channel and reduces the frequency and cost of cleaning and maintenance. The shape of the herringbone water guiding channel gives the channel wall strong compressive strength, especially when bearing external loads (such as water accumulation, snow weight, etc.), it can effectively disperse pressure and reduce the deformation or cracking of the channel.

[0026] The reinforcing bars in rib 2 are arranged at an angle. By arranging the reinforcing bars at an angle, rib 2 can more evenly distribute bending moment and shear force, thereby improving the stability of the entire structure and reducing the risk of local plastic deformation and failure. The reinforcing bars in rib 2 are welded and fixed to the reinforcing bars in wall panel 1.

[0027] In this embodiment, wall panel 1 and rib 2 are integrally formed, and wall panel 1 and rib 2 are double-T shaped. The T-shaped structure usually has a better balance between weight and size, making transportation and hoisting more convenient. At the same time, due to its unique structure, the T-shaped wall panel 1 can reduce the overall weight while maintaining the strength and stability of wall panel 1. Rib 2 is connected to the building's support system. In this solution, a model is made in the prefabrication plant using PVC board or steel plate, the reinforcing bars are tied, the connectors are placed in the corresponding positions of the model, and fiber concrete is poured into the model to complete the fabrication of wall panel 1, rib 2, and connectors. After fabrication, ropes are used to bind them, and a 10t crane is used to hoist them onto a truck. At the installation site, a 10t crane is used for hoisting and installation. Through this prefabrication of wall panel 1 and rib 2, the installation of external wall panels can be completed quickly and easily, greatly improving the construction speed.

[0028] The connector is fixed to wall panel 1 and is used to connect wall panel 1 to the building's support system. At the installation site, the external wall panel is installed onto the building's support system using the connector, completing the installation of the external wall panel. The connector facilitates the installation of the external wall panel onto the building's support system, reducing construction difficulty.

[0029] The connector includes screw sleeves, which are used to connect bolts or screws. The screw sleeves are fixed to the wall panel 1 by concrete pouring. Multiple screw sleeves are provided and evenly distributed on the wall panel 1. The multiple screw sleeves enhance the connection stability between the wall panel 1 and the building's support system.

[0030] The screw sleeve includes a sleeve 3 and a reinforcing bar. The reinforcing bar is fixed to the outside of the sleeve 3, specifically welded to the sleeve 3. The sleeve 3 has threads that mate with bolts or screws. The reinforcing bar further strengthens the structure of the sleeve 3 and increases the contact area between the sleeve 3 and the fiber-reinforced concrete, thereby increasing the connection stability between the sleeve 3 and the wall panel 1. The length of the sleeve 3 is greater than the thickness of the wall panel 1 to facilitate screw installation.

[0031] The reinforcing bars in the screw sleeve are fixedly connected to the reinforcing bars in wall panel 1. This further increases the connection stability between sleeve 3 and wall panel 1.

[0032] The sleeve 3 is perpendicular to the wall panel 1. The outer wall of the sleeve 3 is provided with burrs. The burrs can increase the contact area between the sleeve 3 and the concrete, which can help the sleeve to evenly distribute the external load in the concrete, thus helping to improve the load-bearing capacity of the object and thus increase the load-bearing capacity of the object. The burrs can also be effectively embedded in the concrete surface, enhancing the adhesion between the sleeve 3 and the concrete and reducing the possibility of the sleeve 3 slipping or loosening.

[0033] The wall panel 1 has connecting strips 4 at both ends to connect with adjacent wall panels 1. These connecting strips 4 are formed by mixing an expanding agent and joint filler. The expanding agent is an additive used in concrete or mortar, whose main function is to cause the concrete or mortar to expand during the hardening process through a chemical reaction. This expansion effectively counteracts shrinkage caused by moisture evaporation or temperature changes, reducing cracking and deformation, and improving the density and crack resistance of the concrete or mortar. Joint filler is a material used to fill joints, gaps, and holes in prefabricated buildings. Joint filler typically has good adhesion, flowability, water resistance, and durability, providing a smooth and dense connection between prefabricated components. The use of joint filler improves the overall structural strength and sealing of prefabricated buildings.

[0034] This design utilizes rib 2 to increase the stiffness of wall panel 1, effectively enhancing its bending resistance. Ribs 2 also help wall panel 1 more effectively transfer shear force when encountering lateral forces (such as wind or seismic forces), thus improving its shear resistance. The hollow design of rib 2 reduces the density and weight of the panel by creating hollow areas, without affecting its structural strength. After prefabrication and curing at the prefabrication yard to achieve sufficient strength, the panels can be hoisted, with individual panel heights matching the floor height, eliminating the need for a frame. Wall panel 1 is connected to beams via bolts and screws, facilitating installation, accelerating construction, and providing strong wind and earthquake resistance. This design is suitable for the exterior wall construction of industrial plants, commercial buildings, and large public buildings. Connectors facilitate the installation of the external wall panels onto the building's support system, reducing construction difficulty.
