Description

Technical Field

[0001] The invention belongs to the technical field of building wall materials, and in particular relates to an assembled wall formwork-free shell and an assembled lightweight concrete wall. Background Art

[0002] In the traditional technology of concrete wall pouring construction, in order to ensure the shape stability and bearing capacity of concrete during the pouring process, it is usually necessary to use a formwork with a certain structural strength to support and shape it. These formworks mainly include wooden formworks, steel formworks and aluminum formworks, each of which has specific advantages, but also comes with some disadvantages that cannot be ignored. Although the cost of wooden formworks is relatively low, its service life is limited and it is susceptible to moisture, deformation and corrosion; steel formworks and aluminum formworks have higher strength and durability, but the cost is higher, and a lot of lifting and transportation work is required during the construction process. More importantly, no matter which type of formwork is used, it needs to be dismantled after the building is completed, which not only increases the construction cost, but also prolongs the construction period. At the same time, the waste generated during the dismantling process may also pollute the environment.

[0003] In order to overcome these limitations of traditional formwork technology, some non-removal formwork technologies have emerged on the market. These technologies aim to simplify the construction process, reduce costs and improve efficiency by omitting the process of removing the formwork at a later stage. However, the existing non-removal formwork technology still exposes many shortcomings in practical applications. For example, the installation efficiency is low, and a lot of manpower and time are required for assembly and fixation; the fixing effect is poor, and the connection between the formworks or between the formworks and the wall is not firm, which easily leads to leakage or shape distortion of concrete during the pouring process; in addition, the strength and durability of some non-removal formworks do not meet the requirements of long-term use.

[0004] Under this environment, the construction industry has an increasingly urgent need for a new wall material that combines multiple advantages such as high strength, environmental protection, heat preservation, light weight, durability, and waste recycling. Therefore, the present invention proposes an innovative assembled wall formwork-free assembly and an assembled lightweight concrete wall. Summary of the invention

[0010] Preferably, the first truss connector or the second truss connector is a steel truss single-chord support connector, and the steel truss single-chord support connector is provided with a connecting portion for inserting a connecting bolt and a self-locking clamping portion for clamping the upper chord of the steel truss.

[0011] Preferably, the self-locking clamping portion includes a V-shaped bayonet, in which symmetrically arranged elastic locking portions are provided, the two elastic locking portions are arranged in a V-shape, and the bottom is a disconnected structure, the distance at the disconnection point is smaller than the outer diameter of the upper chord steel bar of the steel truss, and a deformation space is provided between the elastic locking portion and the side wall of the V-shaped bayonet.

[0012] Preferably, the bottom of the V-shaped buckle is an arc-shaped structure, and the radius of the arc-shaped structure is equal to the radius of the upper chord steel bar of the reinforcement truss;

[0013] Preferably, the surfaces of the inner and outer formwork are compounded with an anti-cracking mortar layer, and a 3-10 mm edge sealing groove is left on the surface of the anti-cracking mortar layer away from the edge of the formwork.

[0014] Preferably, it also includes an insulation board arranged on the inner side of the outer formwork to form an assembled exterior wall insulation formwork that does not need to be disassembled.

[0015] Preferably, a hollow support bracket is provided at each mounting hole position corresponding to each outer template, and the support bracket forms casting cavities with equal spacing between the insulation board and the outer template.

[0016] The present invention also relates to an assembled lightweight concrete wall, comprising a non-disassembly formwork, wherein the non-disassembly formwork adopts the above-mentioned non-disassembly formwork, lightweight concrete is poured in the non-disassembly formwork to form a lightweight wall module, and adjacent lightweight wall modules are spliced ​​to form a lightweight wall.

[0017] The present invention also relates to an assembled lightweight concrete wall which is an assembled lightweight thermal insulation wall, comprising a non-disassembly formwork and an insulation board. The non-disassembly formwork adopts the above-mentioned non-disassembly formwork, and lightweight concrete is poured in a pouring cavity formed between an inner formwork component and an outer formwork component of the insulation board to form a lightweight wall module. Adjacent lightweight thermal insulation wall modules are spliced ​​to form a lightweight thermal insulation wall.

[0018] The advantages and technical effects of the present invention are as follows: a prefabricated wall without dismantling the formwork and a prefabricated lightweight concrete wall, which exhibits a number of significant technical advantages and practical application values. The following is a detailed summary of its advantages:

[0019] First of all, the non-dismantling formwork realizes effective support and shaping of concrete during the pouring process through the ingenious design of the internal and external formwork components. The internal and external formwork components together constitute the main structure of the non-dismantling formwork, ensuring the shape stability and bearing capacity of the concrete during the pouring process, thereby greatly improving the construction quality and efficiency of the building wall. This design not only simplifies the construction process, but also reduces the construction cost, which is in line with the pursuit of modern buildings for efficient and environmentally friendly construction concepts.

[0020] Secondly, the design of the mounting holes and fixing nuts on the non-dismantling formwork provides a secure mounting position for the inner and outer formwork connecting bolts. This design not only enhances the stability and load-bearing capacity of the formwork, but also makes the removal and reinstallation of the formwork more convenient and quick. At the same time, the steel truss between the first truss connector and the second truss connector serves as a supporting structure, further enhancing the overall strength and stability of the non-dismantling formwork, so that the inner and outer formwork components form a solid whole that can withstand greater pouring pressure and load.

[0021] In addition, the non-removable formwork also adopts innovative designs such as anti-crack mortar layer and insulation board. The application of anti-crack mortar layer effectively resists the cracking caused by temperature changes, shrinkage and other factors during the hardening process of concrete, and improves the overall crack resistance and durability of the wall. The setting of insulation board significantly enhances the thermal insulation performance of the wall, reduces the energy consumption of the building, and improves energy efficiency. These designs not only improve the performance of the wall, but also meet the high requirements of modern architecture for aesthetics and details.

[0022] When the non-dismantling formwork is applied to assembled lightweight concrete walls, its advantages are more prominent. The pouring of lightweight concrete reduces the weight of the wall module, making it easier to carry and install, and reducing the load requirements on the foundation structure. At the same time, lightweight concrete has good thermal insulation and heat insulation properties, which, together with the non-dismantling formwork and insulation board, further improves the energy-saving effect of the wall. Adjacent lightweight wall modules are spliced ​​together to form a complete lightweight wall, and the joints are tight and firm, ensuring the integrity and stability of the wall. This assembled lightweight concrete wall technology, with its high efficiency, environmental protection, energy saving and stability, provides a new and high-quality wall solution for modern buildings.

[0023] In summary, a prefabricated wall without formwork removal and prefabricated lightweight concrete wall have shown significant technical advantages and practical application value in many aspects. It not only simplifies the construction process, improves construction efficiency and quality, but also reduces energy consumption and costs, and meets the needs of modern buildings for high efficiency, environmental protection, energy saving, and aesthetics. Therefore, this technology has broad application prospects and promotion value in the construction industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Example 1, please refer to Figures 1 to 6 , an assembled wall formwork that does not require disassembly, includes an inner formwork component 1 and an outer formwork component 2, the inner formwork component and the outer formwork component together constitute the main structure of the formwork that does not require disassembly, and are used to support and shape the concrete during the pouring process. Through the combination of the inner and outer formworks, the shape stability and bearing capacity of the concrete during the pouring process are ensured. The inner formwork component 1 includes an inner formwork 1-1, and the inner formwork is provided with a plurality of mounting holes 1-2 along the laying direction of the steel bar truss, and an inner formwork truss fixing nut 1-3 is fixedly installed in the mounting hole; one side of the inner formwork is fixedly connected to a first truss connector 1-5 through an inner formwork connecting bolt 1-4, and the mounting hole is used to fix the inner formwork truss fixing nut, providing an installation position for the inner formwork connecting bolt, so that the inner formwork connecting bolt can be firmly fixed on the inner formwork, thereby enhancing the stability and bearing capacity of the formwork; the inner formwork connecting bolt is threadedly connected to the inner formwork truss fixing nut; the first truss connector is firmly fixed to the inner formwork through a threaded connection, thereby ensuring a tight connection between the first truss connector and the inner formwork, thereby improving the strength and stability of the overall structure.

[0037] The outer formwork assembly 2 includes an outer formwork 2-1, on which a plurality of mounting holes 2-2 are provided along the laying direction of the steel trusses, and outer formwork truss fixing nuts 2-3 are installed and fixed in the mounting holes. Similar to the outer formwork assembly, an installation position is provided for the outer formwork connecting bolts, and the outer formwork truss fixing nuts are fixed, so that the outer formwork connecting bolts 2-4 can be firmly fixed on the outer formwork, thereby enhancing the stability and bearing capacity of the outer formwork; a second truss connector 2-5 is fixedly installed on the inner side of the outer formwork by the outer formwork connecting bolts, and the outer formwork connecting bolts are threadedly connected to the outer formwork truss fixing nuts; the second truss connector is firmly fixed to the outer formwork through the threaded connection, thereby ensuring the tight connection between the second truss connector and the outer formwork, thereby improving the strength and stability of the overall structure.

[0038] A steel truss 3 is connected between the first truss connector and the second truss connector; the steel truss serves as a supporting structure, connecting the first truss connector and the second truss connector to enhance the overall strength and stability of the non-removal formwork. Through the connection of the steel truss, the inner and outer formwork components form a solid whole that can withstand greater casting pressure and load, thereby ensuring the shape stability and bearing capacity of the non-removal formwork during the casting process.

[0039] The present invention proposes an innovative assembled wall formwork that does not require disassembly, which has significant technical effects, which are specifically reflected in the following aspects:

[0040] First of all, the non-dismantling formwork is cleverly designed with internal and external formwork components. Both the internal and external formworks use pressure limit plates or calcium silicate boards and other formworks with a certain strength, which effectively supports and shapes the concrete during the pouring process. The internal and external formwork components together constitute the main structure of the non-dismantling formwork, ensuring the shape stability and bearing capacity of the concrete during the pouring process, thereby greatly improving the construction quality and efficiency of the building wall.

[0041] Secondly, the design of the mounting holes and fixing nuts on the inner and outer formwork assemblies provides a secure mounting position for the inner and outer formwork connecting bolts. This design not only enhances the stability and load-bearing capacity of the formwork, but also makes the removal and reinstallation of the formwork more convenient and quick, reducing construction costs.

[0042] In addition, the steel truss between the first truss connector and the second truss connector serves as a supporting structure, further enhancing the overall strength and stability of the non-removal formwork. The connection of the steel truss allows the inner and outer formwork components to form a solid whole that can withstand greater pouring pressure and load, thereby ensuring the shape stability and load-bearing capacity of the non-removal formwork during the pouring process.

[0043] Preferably, see Figure 4a, the first truss connector or the second truss connector is a steel truss double-chord support connector, and the steel truss double-chord support connector is provided with a connecting portion 1-50 for inserting a connecting bolt and a self-locking clamping portion 1-51 for clamping the lower chord of the steel truss; the connecting portion is provided with one or two connecting bolt mounting holes 1-52; the self-locking clamping portion is arranged on both sides of the double-chord support connection member, and the self-locking clamping portion includes a steel truss lower chord guide surface 1-510 located above, and the lower dead point of the lower chord guide surface is provided with a U-shaped clamping groove 1-53 recessed toward the center of the support connection member; the center distance between the two U-shaped clamping grooves is not greater than the center distance between the two lower chords of the steel truss in the natural state. The steel truss double-chord support connector plays an important role in the prefabricated wall formwork, and its effects and advantages are remarkable. Specifically, the connector, through its unique structural design, not only provides a stable installation position for the connecting bolts, but also realizes the firm clamping of the lower chord of the steel truss through the self-locking clamping portion. This design ensures a tight connection between the steel truss and the inner and outer formwork components, further enhancing the overall strength and stability of the non-dismantling formwork. At the same time, the U-shaped clamping groove design of the self-locking clamping part can effectively adapt to and fix the lower chord of the steel truss to prevent it from displacement or deformation during the pouring process, thereby ensuring the shape stability and bearing capacity of the non-dismantling formwork during the pouring process. Overall, the application of the steel truss double-chord support connector has greatly improved the construction quality and efficiency of the non-dismantling formwork, providing a more reliable and efficient construction method for modern buildings.

[0044] Preferably, see Figure 4b A hollow structure is provided on the double-chord support connector of the steel truss, and the hollow space content can form slurry holes, so that the pouring of lightweight concrete is uninterrupted and its strength is guaranteed.

[0045] Preferably, the first truss connector or the second truss connector is a steel truss single-chord support connector, which is L-shaped and is provided with a connecting portion 2-50 for inserting a connecting bolt and a self-locking clamping portion 2-51 for clamping the upper chord of the steel truss.

[0046] Preferably, the self-locking clamping portion includes a V-shaped bayonet 2-52, in which a symmetrically arranged elastic locking portion 2-53 is provided, the two elastic locking portions are arranged in a V shape, and the bottom is a disconnected structure, the distance at the disconnection point is smaller than the outer diameter of the upper chord steel bar of the steel truss, and a deformation space is provided between the elastic locking portion and the side wall of the V-shaped bayonet.

[0047] Preferably, the bottom of the V-shaped buckle is an arc-shaped structure, and the radius of the arc-shaped structure is equal to the radius of the upper chord steel bar of the reinforcement truss.

[0048] The steel truss single-chord support connector plays an important role in the prefabricated wall formwork, and its design and function have demonstrated remarkable effects. Specifically, the connector not only provides a stable installation position for the connecting bolts through its unique structural design, but also achieves a firm clamping of the upper chord of the steel truss through the self-locking clamping part. The self-locking clamping part includes a V-shaped bayonet and a symmetrically arranged elastic locking part. This design enables the connector to effectively adapt to and fix the upper chord of the steel truss to prevent displacement or deformation during the pouring process. At the same time, the arc-shaped structure at the bottom of the V-shaped buckle and the deformation space between it and the elastic locking part further enhance the firmness and adaptability of the clamping.

[0049] In practical applications, the steel truss single-chord support connector has demonstrated its flexibility and practicality. When a three-chord steel truss is selected, a steel truss single-chord support connector can be used on one side and a double-chord connector on the other side to meet different construction requirements. When a single-piece truss is selected, steel truss single-chord support connectors are used on both sides to ensure the stability of the steel truss and the strength of the overall structure. This flexible combination makes the application of steel truss single-chord support connectors in prefabricated wall formwork free of removal more extensive and efficient.

[0050] In summary, the steel truss single-chord support connector provides a more stable and reliable connection method for the prefabricated wall without dismantling the formwork through its unique design and superior performance, greatly improving the construction quality and efficiency. At the same time, its flexible combination method also enables it to play the best effect in different construction scenarios.

[0051] Preferably, the surfaces of the inner and outer templates are compounded with an anti-cracking mortar layer 1-6, and a sealing edge groove 1-7 of 3-10 mm is left on the surface of the anti-cracking mortar layer from the edge of the template.

[0052] The technical effects of this technical feature are mainly reflected in the following aspects:

[0053] 1. Enhance crack resistance

[0054] Function of anti-crack mortar layer: Anti-crack mortar layer is a material layer with excellent anti-crack performance, which can effectively resist the cracking of concrete caused by temperature changes, shrinkage and other factors during the hardening process. Compounding anti-crack mortar layer on the surface of formwork can directly act on the concrete surface, reduce the occurrence of cracks, and improve the overall crack resistance of the wall.

[0055] 2. Improve durability

[0056] Protect the edge of the formwork: The design of the edge sealing groove allows a certain distance between the anti-cracking mortar layer and the edge of the formwork, which helps to prevent the mortar layer from being damaged at the edge of the formwork due to collision, friction and other factors during construction. At the same time, the edge sealing groove can also serve as an expansion joint of the mortar layer, allowing the mortar layer to have a certain expansion space when the temperature changes, reducing cracking caused by stress concentration.

[0057] Extended service life: By enhancing crack resistance and protecting the edges of the formwork, this technical feature helps improve the durability of the wall and extend the service life of the building.

[0058] 3. Improve construction effect

[0059] Improve construction accuracy: The design of the edge sealing groove enables construction workers to more easily control the thickness and uniformity of the mortar layer when applying the anti-cracking mortar layer, thereby improving construction accuracy.

[0060] Simplify the construction process: directly compounding the anti-cracking mortar layer on the surface of the formwork can simplify the construction process, reduce construction procedures and improve construction efficiency.

[0061] 4. Improve aesthetics

[0062] Smooth and beautiful wall: The surface of the anti-crack mortar layer is smooth and beautiful, which can enhance the overall visual effect of the wall. Although the design of the edge sealing groove is small, it reflects the fineness of the construction and the pursuit of aesthetics in detail.

[0063] In summary, the technical features of the composite anti-crack mortar layer on the surface of the inner and outer formwork and the edge sealing grooves have significant technical effects in enhancing anti-crack performance, improving durability, improving construction effects and enhancing aesthetics. This design not only helps to improve the quality and service life of the building, but also meets the high requirements of modern architecture for appearance and details.

[0064] Example 2, please refer to Figure 7In this embodiment, on the basis of Example 1, an insulation board 4 is also included on the inner side of the outer formwork to form an assembled external wall insulation non-disassembly formwork with insulation. An insulation board is added on the basis of the above-mentioned formwork to form an assembled external wall insulation non-disassembly formwork with insulation. This technical improvement brings remarkable results. The setting of the insulation board effectively enhances the thermal insulation performance of the wall, reduces the energy consumption of the building, and improves the energy utilization efficiency. At the same time, since the insulation board is set on the inner side of the outer formwork and is carried out synchronously with the concrete pouring process, it will not have an additional impact on the construction progress, and maintains the efficient construction advantage of the assembled wall non-disassembly formwork. In addition, the combination of the insulation board, the formwork and the steel truss forms an integral structure, which improves the stability and bearing capacity of the wall. This assembled external wall insulation non-disassembly formwork with insulation not only meets the high requirements of modern buildings for thermal insulation performance, but also maintains the high efficiency, environmental protection and economic characteristics of assembled construction, providing a more advanced and practical construction method for the construction industry.

[0065] Preferably, a hollow support bracket 5 is provided at each mounting hole position of each outer template, and the support bracket forms a casting cavity with equal spacing between the insulation board and the outer template. The technical effects are mainly reflected in the following aspects:

[0066] Ensure consistent spacing: The design of the support bracket ensures a constant spacing between the insulation board and the outer formwork, which helps to form a uniform protective layer during the pouring process and improves the overall performance and appearance quality of the wall.

[0067] Forming a protective layer: During pouring, concrete will fill the pouring cavity formed between the support bracket, the outer formwork, and the insulation board, and form a solid protective layer after solidification. This protective layer not only enhances the structural strength of the wall, but also effectively isolates the impact of the external environment on the insulation board, extending the service life of the insulation layer.

[0068] Improve construction efficiency: As prefabricated components, support brackets can be quickly installed on the construction site without additional measurement and adjustment, which greatly improves construction efficiency. At the same time, they also provide stable support for concrete pouring, ensuring the smooth progress of the construction process.

[0069] Enhanced insulation effect: Since the insulation board and the outer formwork maintain a constant distance, this helps reduce the thermal bridge effect and improve the insulation performance of the wall. The insulation layer can more effectively block the intrusion of cold and hot air from the outside and maintain a stable indoor temperature.

[0070] Improve the overall structural stability: The support bracket, insulation board, external formwork and steel truss together form an integral structure, which enhances the stability and bearing capacity of the wall. This design makes the prefabricated external wall insulation non-removal formwork more resistant to various external forces.

[0071] In summary, this technical feature not only ensures the distance between the outer formwork and the insulation board by setting a hollow support bracket, but also forms a solid protective layer after pouring, thereby improving the insulation effect, overall performance and construction efficiency of the wall.

[0072] The present invention also relates to an assembled lightweight concrete wall, see Figure 8 , including a non-disassembly formwork, the non-disassembly formwork adopts the non-disassembly formwork of the above-mentioned embodiment 1, lightweight concrete is poured in the non-disassembly formwork to form a lightweight wall module, and adjacent lightweight wall modules are spliced ​​to form a lightweight wall.

[0073] The technical effect of the assembled lightweight concrete wall is remarkable, which is mainly reflected in the following aspects: First, by adopting the non-dismantling formwork technology, the construction process is greatly simplified, the construction efficiency is improved, and the construction cost is reduced. As a permanent part of the wall, the non-dismantling formwork does not need to be removed after pouring, which reduces the generation of construction waste and conforms to the green and environmentally friendly construction concept. Secondly, the pouring of lightweight concrete reduces the weight of the wall module, facilitates transportation and installation, reduces the load requirements on the foundation structure, and improves the overall safety of the building. At the same time, lightweight concrete has good thermal insulation and heat insulation properties, which effectively improves the energy-saving effect of the wall. Finally, the adjacent lightweight wall modules are spliced ​​to form a complete lightweight wall, and the splicing is tight and firm, ensuring the integrity and stability of the wall. In summary, the assembled lightweight concrete wall technology provides a new and high-quality wall solution for modern buildings with its high efficiency, environmental protection, energy saving and stability.

[0074] See also Fig. 9 The present invention also relates to an assembled lightweight concrete wall, which is an assembled lightweight thermal insulation wall, comprising a non-disassembly formwork and an insulation board. The non-disassembly formwork adopts the non-disassembly formwork described in the above embodiment 2. A casting cavity is formed between an inner formwork component and an outer formwork component of the insulation board, and lightweight concrete is cast in the casting cavity to form a lightweight wall module. Adjacent lightweight thermal insulation wall modules are spliced ​​to form a lightweight thermal insulation wall.

[0075] The technical effect of the assembled lightweight concrete wall with insulation board is remarkable, which is mainly reflected in the following aspects: First, by adopting the design of combining the non-disassembly formwork and the insulation board, it is possible to cast lightweight concrete in the casting cavity, forming a lightweight wall module with excellent insulation performance, which greatly improves the energy-saving effect of the wall.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
