[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] As mentioned in the background technology, the traditional hollow slab beam construction method has some problems, such as complex template installation, difficult template removal, and material waste.

[0036] In order to improve the above-mentioned problems, the present application proposes an inner mold for a hollow slab beam for a highway bridge, which adopts a design in which a support tube is arranged on the outer surface of the support assembly, so that the support assembly can be easily pulled out after the concrete dries. At the same time, multiple support tubes can be made to fall off by gently hitting with a hammer, so that the support tubes can be reused. This design not only simplifies the installation and disassembly process of the formwork, but also improves the utilization rate of materials and reduces construction costs. The support assembly of the mold consists of four support bodies, which are easy to assemble and can be disassembled and assembled according to the actual length. This modular design enables the mold to adapt to the construction requirements of hollow slab beams of different lengths and widths, and improves the flexibility and adaptability of the construction.

[0037] See also Figure 1-5 As shown, according to an embodiment of the present application, an inner mold die for a hollow slab beam for a highway bridge comprises:

[0038] A support assembly 1, wherein a plurality of support assemblies 1 are provided, wherein the plurality of support assemblies 1 are arranged in a straight line, and corresponding ends of two adjacent support assemblies 1 among the plurality of support assemblies 1 are fixedly connected;

[0039] The support tubes 2 are arranged in a ring array with the transverse axis of the multiple support components 1 as the axis, and two adjacent support tubes 2 are arranged in close proximity to each other. The multiple support tubes 2 form a protective sleeve to sleeve the multiple support components 1 inside the multiple support tubes 2.

[0040] Specifically, by arranging the support tube 2 on the outer surface of the support assembly 1, the support assembly 1 can be easily pulled out after the concrete dries. At the same time, a plurality of support tubes 2 can be dropped by a light hit with a hammer, so that the support tubes 2 can be reused. This design simplifies the installation and disassembly process of the template and improves the construction efficiency. The support assembly 1 is composed of four support bodies 6, which are easy to assemble and can be disassembled and assembled according to the actual length. This modular design enables the mold to adapt to the construction requirements of hollow slab beams of different lengths and widths, and improves the flexibility and adaptability of the construction.

[0041] Since the support tube 2 can be reused, the waste of disposable materials is reduced, and the construction cost is reduced. The precisely designed support assembly 1 and support tube 2 ensure the dimensional accuracy and surface quality of the hollow slab beam, thereby improving the overall project quality. The simplified installation and disassembly process reduces the time workers spend working at heights and reduces safety risks. Due to the reduced use and waste of materials, the mold has less impact on the environment and conforms to the concept of green building. Although the initial investment may be high, due to its reusability and saved labor costs, it has good economic benefits in the long run. The mold is suitable for various types of highway bridge construction and has broad application prospects. The inner mold mold for hollow slab beams for highway bridges of this application provides an efficient, economical, safe and environmentally friendly solution, which helps to promote the development of highway bridge construction technology.

[0042] In some specific embodiments, the support assembly 1 includes:

[0043] Square tube 3, the inner diameter of the right end of square tube 3 is larger than the inner diameter of the left end of square tube 3, and the left end of square tube 3 can be inserted into the right end of the adjacent square tube 3, and the inner diameter of the right end of square tube 3 matches the outer diameter of the left end of square tube 3;

[0044] The frame assembly 4 is provided with two frame assemblies 4 on one square tube 3 , and the two frame assemblies 4 are arranged at intervals along the two ends of the square tube 3 .

[0045] Specifically, the square tube 3 has a rectangular cross-section. The design of the square tube 3 allows the inner diameter of the right end to be larger than the inner diameter of the left end. This tapered structure allows adjacent square tubes to be easily inserted and fixed together. This design simplifies the assembly process of the mold, allowing construction workers to quickly connect multiple square tubes 3 to form the required support structure. At the same time, this structure is also easy to disassemble after the construction is completed. Simply pull the square tube out from the other end, which greatly improves construction efficiency and saves valuable time and human resources.

[0046] The frame components 4 are arranged at intervals along the two ends of the square tube 3. This design increases the stability of the entire support structure. During the pouring and curing of concrete, the mold may be deformed or displaced due to the influence of gravity and external forces. However, by arranging two frame components 4 on the square tube and arranging them at intervals along the two ends of the square tube, these forces can be effectively resisted to ensure that the mold maintains its original shape and position, thereby ensuring the quality of the project; since the square tubes 3 can be inserted into each other, this design allows the length of the support component 1 to be adjusted according to the actual required beam length. Whether it is a shorter beam or a longer beam, the demand can be met by increasing or decreasing the number of square tubes 3. This flexibility makes the mold suitable for a variety of different engineering projects and has strong adaptability.

[0047] The structural design of the square tube 3 and the frame assembly 4 is easy to disassemble and reassemble, which allows the mold to be reused in multiple projects. Compared with traditional disposable molds, this reusable mold can not only reduce long-term cost investment, but also reduce the waste of resources. After each use, the square tube 3 and the frame assembly 4 only need to be cleaned and maintained before they can be put into use again, thereby maximizing economic benefits; the simplified assembly and disassembly process reduces the time of aerial work. In traditional construction methods, workers need to perform complex assembly and disassembly work at high altitudes, which is not only time-consuming and labor-intensive, but also poses great safety risks. However, after adopting this new design of support assembly 1, workers can complete most of the work on the ground and only perform simple aerial work when necessary, thereby greatly reducing the safety risks of workers.

[0048] This design helps to reduce the overall construction cost by reducing material waste and labor costs. Traditional disposable molds not only consume a lot of material resources, but also require a lot of manpower for installation and disassembly. After adopting this new support component 1 design, due to its reusability and rapid assembly characteristics, the use of materials and labor can be significantly reduced, thereby reducing construction costs; reusable design and reduced material consumption are in line with the concept of sustainable development. In the context of increasingly serious global environmental problems, the use of environmentally friendly construction methods and materials has become an inevitable trend. This new support component 1 design is developed based on this concept. It not only reduces the consumption of natural resources, but also reduces the generation and disposal of waste, and has less impact on the environment; precise structure and component matching ensure the dimensional accuracy and surface quality of the hollow slab beam. In bridge construction, the dimensional accuracy and surface quality of the hollow slab beam are crucial to the quality of the entire project. After adopting this new support component 1 design, due to its precise structure and component matching relationship and stable support effect, it can effectively ensure that the dimensional accuracy and surface quality of the hollow slab beam meet the design requirements. This can not only improve the overall quality level of the project, but also extend the service life and maintenance cycle of the bridge.

[0049] In some specific embodiments, through holes 5 for connecting pins to pass through are provided at both ends of the square tube 3 , and the corresponding ends of two adjacent square tubes 3 are sleeved on each other and fixedly connected by connecting pins passing through the through holes 5 .

[0050] Specifically, by providing through holes 5 for connecting pins to pass through at both ends of the square tubes 3, the corresponding ends of two adjacent square tubes 3 can be sleeved together and fixedly connected by connecting pins. This design can ensure that the connection between the square tubes is more firm and stable, and prevent loosening or falling off during use. At the same time, the use of connecting pins can also increase the number of connection points, further improve the stability of the overall structure, and facilitate assembly and disassembly.

[0051] Since the design of the connecting pin is simple and easy to operate, construction workers can quickly connect or disassemble the square tubes 3 together. This design simplifies the assembly and disassembly process and improves construction efficiency. In addition, the use of connecting pins can also reduce damage to the square tubes and extend their service life; Enhance structural strength: The use of connecting pins can not only improve the connection stability between the square tubes, but also enhance the bearing capacity of the entire structure. During the pouring and curing of concrete, the mold may be deformed or displaced due to the influence of gravity and external forces. However, by using connecting pins to tightly connect the square tubes together, the effects of these forces can be effectively resisted, ensuring that the mold maintains its original shape and position, thereby ensuring the quality of the project; Adapting to different length requirements.

[0052] Since the square tubes can be inserted into each other and fixedly connected by connecting pins, this design allows the length of the support assembly to be adjusted according to the actual required beam length. Whether it is a shorter beam or a longer beam, the demand can be met by increasing or decreasing the number of square tubes and connecting them with connecting pins. This flexibility makes the mold suitable for a variety of different engineering projects and has strong adaptability; the simplified assembly and disassembly process reduces the time of high-altitude work. In traditional construction methods, workers need to perform complex assembly and disassembly work at high altitudes, which is not only time-consuming and labor-intensive, but also poses great safety risks. However, after adopting this new support assembly design, workers can complete most of the work on the ground and only perform simple high-altitude work when necessary, thereby greatly reducing the safety risks of workers; the reusable design and reduced material consumption are in line with the concept of sustainable development. In the context of the current increasingly serious global environmental problems, the use of environmentally friendly construction methods and materials has become an inevitable trend. This new support assembly 1 design is developed based on this concept. It not only reduces the consumption of natural resources, but also reduces the generation and disposal of waste, and has less impact on the environment.

[0053] In some specific embodiments, the two frame components 4 coincide with the axis of the square tube 3 .

[0054] In some specific embodiments, the square tube 3 is arranged horizontally.

[0055] In some specific embodiments, the square tube 3 is a hollow structure.

[0056] Specifically, the square tube 3 adopts a hollow structure design, which can significantly reduce the overall weight compared to a solid structure. This lightweight design is not only easy to transport and install, reduces logistics costs and labor intensity, but also reduces the burden on the construction site. In large-scale engineering projects such as bridge construction, the lightness of materials is particularly important because it is directly related to construction efficiency and safety; the square tube 3 with a hollow structure reduces the amount of material used while maintaining sufficient strength. This design is in line with the principle of saving resources, helps to reduce production costs, and also embodies the concept of sustainable development. By optimizing the material structure, a balance between performance and economy is achieved; although the square tube 3 is hollow, its structure has been carefully designed to still provide good support and stability.

[0057] The stability of this structure comes from its geometric shape, wall thickness distribution and possible internal reinforcement rib design, which ensures that it is not easy to deform or damage when bearing loads; for some application scenarios that require internal wiring or pipeline installation, the square tube 3 with a hollow structure provides convenience. Construction personnel can easily arrange wires, cables or other facilities inside the square tube without worrying about insufficient space or installation difficulties; in some specific applications, such as HVAC systems or industrial pipelines, the square tube 3 with a hollow structure helps to improve the heat exchange efficiency. Since air or other media can flow inside the square tube, the transfer and dissipation of heat is promoted, and the energy efficiency of the system is improved; through holes 5 for connecting pins to pass through are provided at both ends of the square tube 3, and two adjacent square tubes can be fixedly connected through these through holes. This design allows multiple square tubes to be connected at different angles and configurations, meeting the diverse needs of complex engineering structures for square tube connection methods. Whether it is a straight line arrangement or a curved combination, it can be easily achieved; the square tube 3 adopts a hollow structure design, which brings many benefits. It not only reduces weight, improves material utilization efficiency, and enhances structural stability, but also facilitates internal wiring or pipeline installation, improves thermal efficiency, adapts to diverse connection requirements, improves aesthetics, and is easy to maintain and clean. These advantages make square tube 3 widely used and recognized in various engineering projects.
