Description

Technical Field

[0001] This application relates to the field of prefabricated building construction technology, and in particular to a prefabricated wall casting module frame. Background Technology

[0002] With the continuous improvement of the level of industrialization in the construction industry, precast wall panels are widely used in various construction projects due to their advantages such as high construction efficiency, energy saving and environmental protection, and controllable quality. The formwork system is the core link to ensure the quality of precast wall panel casting and control the construction progress, directly determining the overall efficiency of construction. Currently, the traditional formwork commonly used in construction projects is mainly wooden formwork and steel formwork, which have many unavoidable defects in actual construction applications.

[0003] Traditional formwork installation is cumbersome, requiring a large amount of manual labor for on-site erection, splicing, and reinforcement. The complex construction process significantly prolongs the overall construction cycle. After pouring, formwork removal is also necessary, leading to high labor costs, frequent damage and deformation of the formwork, and extremely high material wastage rates, failing to meet energy-saving and environmentally friendly construction requirements. Furthermore, traditional formwork is heavy, making transportation, hoisting, and handling difficult, resulting in low reuse efficiency and further increasing construction costs and complexity. Therefore, to address the numerous drawbacks of traditional formwork, there is an urgent need to develop a new, convenient, and efficient formwork system adapted to prefabricated assembly construction to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] In view of the problems of high material loss rate, high construction cost and high construction difficulty in existing technologies, this application mainly provides a prefabricated wall casting module frame.

[0005] To achieve the above objectives, the first technical solution adopted in this application is: a prefabricated wall casting module frame, comprising: a non-removable reinforced expanded mesh, which is connected to the end precast concrete skeleton to form a casting cavity that is closed on the left and right sides and open on the top and bottom; an end precast concrete skeleton, which is symmetrically arranged at the ends of the non-removable reinforced expanded mesh, and has pre-embedded stirrups and longitudinal steel bars inside; and an outer insulation board, which is fitted and installed on the outside of the non-removable reinforced expanded mesh, and the outer insulation board is fixedly connected to the non-removable reinforced expanded mesh and the end precast concrete skeleton.

[0006] Optionally, the external insulation panel is made of magnesium oxide board.

[0007] Optionally, the magnesium oxide board is fixedly connected to the non-removable reinforced expanded mesh and the precast concrete frame at the ends using dovetail nails and expansion plugs.

[0008] Optionally, expansion plugs are pre-placed inside the magnesium oxide board, and dovetail nails penetrate the magnesium oxide board and the non-removable reinforced expanded mesh, with their ends embedded inside the precast concrete frame at the end, so as to fix the magnesium oxide board, the non-removable reinforced expanded mesh and the precast concrete frame at the end into one unit.

[0009] Optionally, the magnesium oxide board completely covers the outer surface of the non-removable reinforced expanded mesh and is flush with the outer surface of the precast concrete frame at the end, forming a flat outer surface of the module.

[0010] Optionally, the compressive strength of the hoop system formed by the reinforcing expanded mesh and stirrups without removal is 1.2-1.5 times that of the hoop system without the reinforcing expanded mesh without removal.

[0011] Optionally, the non-removable reinforced expanded metal mesh is galvanized reinforced expanded metal mesh.

[0012] Optionally, the galvanized reinforced expanded metal mesh is made of galvanized steel sheet, and the surface of the galvanized reinforced expanded metal mesh is galvanized.

[0013] Optionally, the rib spacing of the galvanized reinforced expanded metal mesh is 10cm, and the rib height is 1-8cm.

[0014] Optionally, the end dimensions of the precast concrete frame are 60-200mm.

[0015] The beneficial effects of the technical solution of this application are as follows: When applied, the non-removable reinforced expanded mesh serves as a non-removable formwork, eliminating the need for subsequent dismantling operations. This completely eliminates the cumbersome process of dismantling traditional formwork after pouring, significantly reducing labor input and costs. It also avoids material damage and deformation during formwork dismantling, reducing material waste and significantly shortening the construction cycle while improving construction efficiency. Furthermore, by placing the precast concrete skeleton at only the left and right ends of the module, and using a lightweight non-removable reinforced expanded mesh to enclose the middle to form the pouring cavity, instead of the traditional integral pouring structure, the overall weight of the module is significantly reduced. This greatly reduces the difficulty of transporting, hoisting, and handling the module, facilitating rapid on-site transfer and assembly, and meeting the convenience requirements of prefabricated assembly construction.

Detailed Implementation

[0019] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this application can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this application.

[0020] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0021] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. The specific embodiments described below can be combined with each other to form new embodiments. The same or similar ideas or processes described in one embodiment may not be repeated in other embodiments.

[0022] Figure 1 This is a structural schematic diagram of a specific embodiment of a prefabricated wall casting module frame according to this application. Figure 1 It includes a non-removable reinforced expanded mesh 101 and an end precast concrete frame 102.

[0023] Figure 2 This is a structural schematic diagram of the assembly process of a prefabricated wall casting module frame according to this application. Figure 2 It includes a non-removable reinforced expanded metal mesh 101, an end precast concrete frame 102, an outer insulation board 103, dovetail nails 104, and expansion plugs 105.

[0024] like Figure 1As shown, in a specific embodiment of a prefabricated wall casting module frame of this application, the prefabricated wall casting module frame includes: a non-removable reinforced expanded mesh 101, which is connected to the end precast concrete skeleton to form a casting cavity that is closed from left to right and open from top to bottom.

[0025] In one specific embodiment of this application, the cavity formed by the non-removable reinforced expanded mesh and the precast concrete skeleton at the end can be used for pouring cement slurry.

[0026] In one specific embodiment of this application, the mesh size of the reinforced expanded metal mesh is designed to match the concrete particle size. During concrete pouring, cement slurry fills the mesh openings and quickly sets, creating a "cement slurry sealing the mesh openings" effect, preventing subsequent concrete slurry leakage. Furthermore, it eliminates the need for the traditional formwork removal process after pouring, significantly reducing labor input and costs. Simultaneously, it avoids damage and deformation of the formwork during removal, reducing material waste, significantly shortening the construction cycle, and improving construction efficiency.

[0027] In one specific embodiment of this application, the reinforced expanded metal mesh is not removed, and after pouring, it can become an integral load-bearing structure with the concrete.

[0028] In one specific embodiment of this application, the end concrete frame can be a rectangular body precast in a factory.

[0029] In one specific embodiment of this application, the compressive strength of the hoop system formed by the non-removable reinforced expanded mesh and the stirrups can be 1.2-1.5 times that of the hoop system without the non-removable reinforced expanded mesh.

[0030] As an example, the stirrups inside the precast concrete skeleton at the end can form a longitudinal confinement around the concrete inside the skeleton, limiting the lateral expansion deformation of the concrete under pressure.

[0031] As an example, the reinforced expanded mesh that can be attached to the middle can be used to pour concrete on both sides, forming a transverse hoop constraint that wraps the entire pouring area. Together with the stirrups, it forms a "longitudinal + transverse" double hoop system. The two work together to significantly improve the overall resistance to lateral pressure and compression.

[0032] As an example, reinforced expanded metal mesh can bond deeply with cast-in-place concrete. For instance, the concrete can penetrate the mesh openings and set, making the expanded metal mesh and concrete become one.

[0033] As an example, the stirrups can be tied with the longitudinal bars to form a steel cage, which is then embedded in the precast concrete skeleton at the end. Together with the centrally poured concrete and the expanded mesh, they form a complete stress system, avoiding uneven local stress and further improving compressive strength.

[0034] As an example, stirrups, for instance, in rigid steel reinforcement structures, can provide core compressive support.

[0035] As an example, reinforced expanded metal mesh, such as metal mesh with reinforcing ribs, can combine rigidity with a certain degree of toughness. It can disperse the pressure during concrete pouring and subsequent use, and avoid the strength reduction caused by local stress concentration. The two complement each other and significantly improve the overall compressive strength of the hoop system.

[0036] This can improve the overall compressive strength of the module, resist the lateral pressure during concrete pouring, prevent the module from deforming and expanding during the pouring process, and ensure that the wall panel can withstand the load of the upper part of the building and its own weight after it is formed, thus avoiding problems such as cracking and collapse of the wall panel and ensuring structural safety.

[0037] In one specific embodiment of this application, the non-removable reinforced expanded metal mesh can be galvanized reinforced expanded metal mesh.

[0038] In one specific embodiment of this application, the material of the galvanized reinforced expanded metal mesh can be galvanized steel sheet.

[0039] As an example, the surface of galvanized expanded metal mesh can be galvanized.

[0040] In one specific embodiment of this application, the spacing between the ribs of the galvanized reinforced expanded metal mesh can be 10 cm.

[0041] As an example, the height of the reinforcing bar can be 1-8cm.

[0042] like Figure 1 As shown, in a specific embodiment of a prefabricated wall casting module frame of this application, the prefabricated wall casting module frame includes: an end precast concrete skeleton 102, which is symmetrically arranged at the end of the non-removable reinforced expansion mesh, and has stirrups and longitudinal steel bars embedded inside.

[0043] Therefore, by setting the precast concrete skeleton at the left and right ends of the module and using a lightweight, non-removable reinforced expanded mesh to enclose the middle to form a casting cavity, instead of the traditional integral casting structure, the overall weight of the module is greatly reduced, which greatly reduces the difficulty of transporting, hoisting and handling the module, facilitates rapid on-site transfer and assembly, and meets the convenience requirements of precast assembly construction.

[0044] In one specific embodiment of this application, the end dimensions of the precast concrete frame are 60-200mm. Lightweight and easy to hoist. like Figure 1 As shown, in a specific embodiment of a prefabricated wall casting module frame of this application, the prefabricated wall casting module frame includes: an outer insulation board 103, which is attached to the outside of the non-removable reinforced expanded mesh, and the outer insulation board is fixedly connected to the non-removable reinforced expanded mesh and the end precast concrete skeleton.

[0045] Therefore, the outer insulation board is directly connected to the cast-in-place wall, saving the outer formwork while improving the connection strength by 20%.

[0046] In one specific embodiment of this application, the external insulation panel can be a magnesium oxide board.

[0047] In one specific embodiment of this application, such as Figure 2 As shown, the magnesium oxide board, the non-removable reinforced expanded metal mesh, and the precast concrete frame at the ends can be fixedly connected by dovetail nails 104 and expansion plugs 105.

[0048] In one specific embodiment of this application, such as Figure 2 As shown, the expansion plug 105 can be pre-placed inside the magnesium oxide board, and the dovetail nail 104 can penetrate the magnesium oxide board and the reinforcing mesh that does not need to be removed.

[0049] As an example, the dovetail nail 104 can be embedded in the interior of the precast concrete frame at the end to fix the magnesium oxide board, the non-removable reinforced expanded mesh, and the precast concrete frame at the end into one unit.

[0050] In one specific embodiment of this application, the magnesium oxide board can completely cover the outer surface of the ribbed expanded mesh without the need for removal.

[0051] As an example, the magnesium oxide board can be flush with the outer surface of the precast concrete frame at the end, forming a flat outer surface of the module.

[0052] Therefore, by utilizing the characteristic of the reinforced expanded metal mesh after concrete pouring, the magnesium oxide board is effectively bonded to the concrete without any hollow areas, thus eliminating the need for secondary interior decoration. In one specific embodiment of this application, during construction, connectors can be used to fix the magnesium oxide board, the steel reinforcement frame, and the outer insulation together.

[0053] In one specific embodiment of this application, the connector can be pulled out and reused after the concrete is poured and formed.

[0054] The beneficial effects of the technical solution of this application are as follows: When applied, the non-removable reinforced expanded mesh serves as a non-removable formwork, eliminating the need for subsequent dismantling operations. This completely eliminates the cumbersome process of dismantling traditional formwork after pouring, significantly reducing labor input and costs. It also avoids material damage and deformation during formwork dismantling, reducing material waste and significantly shortening the construction cycle while improving construction efficiency. Furthermore, by placing the precast concrete skeleton at only the left and right ends of the module, and using a lightweight non-removable reinforced expanded mesh to enclose the middle to form the pouring cavity, instead of the traditional integral pouring structure, the overall weight of the module is significantly reduced. This greatly reduces the difficulty of transporting, hoisting, and handling the module, facilitating rapid on-site transfer and assembly, and meeting the convenience requirements of prefabricated assembly construction.
