The solution that can meet the construction progress requirements is secondary pouring, that is, the first pouring of the lower part of the track beam, and the second pouring of the grooved part of the upper part of the track beam. Disadvantages: secondary support formwork is required, which increases the process and wastes resources.

[0008] As a further technical solution, it also includes

[0009] a base mold, the base mold having a grouting cavity,

[0010] A hanging frame, wherein the hanging frame is arranged on the basic mold and is located above the grouting cavity, and the inner mold bottom template is arranged on the hanging frame,

[0011] The inner mold is arranged on the hanging frame and is located in the grouting cavity. The inner mold has the mounting hole, and the mounting hole is used to install the embedded parts. The inner mold also has the mounting space. The mounting space and the grouting cavity are respectively located on both sides of the inner mold.

[0012] As a further technical solution, there are exhaust gaps on both sides of the bottom of the inner mold, and the exhaust gaps connect the grouting cavity and the installation space. The exhaust gaps are formed on the inner mold bottom template, or between the inner mold bottom template and the inner mold side template.

[0013] As a further technical solution, the inner mold bottom template has first arc-shaped portions on both sides, and the lower end of the inner mold side template has a second arc-shaped portion, and the first arc-shaped portion and the second arc-shaped portion overlap each other to form the exhaust gap.

[0014] As a further technical solution, the inner mold side template is raised or lowered relative to the inner mold bottom template, and after the inner mold side template is raised or lowered, the exhaust gap is expanded or reduced.

[0015] As a further technical solution, the inner mold bottom template has a plurality of high-pressure air holes arranged in sequence, and the high-pressure air holes connect the grouting cavity and the installation space, and also include

[0016] A sealing film is arranged on the inner mold bottom template and the inner mold side template facing the grouting cavity.

[0017] As a further technical solution, the inner mold bottom template has a first guide surface, which gradually tilts upward to the exhaust gap.

[0019] A conical nut is placed upside down in a conical hole, and the embedded part is threadedly connected to the conical nut.

[0020] The working principle and beneficial effects of the utility model are:

[0021] The inner mold in the utility model is used to open the groove part of the casting part, and the inner mold bottom template is the basic part of the inner mold, which has a mounting hole for installing the embedded parts. The design and size of the bottom template directly determine the shape of the bottom of the prefabricated component and the precise position of the embedded parts. The inner mold side template is used to cooperate with the inner mold bottom template to enclose the installation space together. The side template is set on the inner mold bottom template. The main function of the side template is to limit the boundary of concrete pouring and ensure that the side shape and size of the prefabricated component meet the design requirements. The installation space is enclosed by the inner mold bottom template and the inner mold side template. This space is used to place the embedded parts and pour concrete. By controlling the position and shape of the inner mold bottom template and the inner mold side template, the position of the embedded parts in the concrete can be ensured to be accurate, and the required closed environment is provided for the curing of the concrete. Through the cooperation of the inner mold bottom template and the inner mold side template, the fixing device for integrated construction of the track beam can realize the precise control of the shape and size of the prefabricated component and the accurate installation of the embedded parts, which is crucial to improving the construction quality and efficiency of the track beam. By quickly installing the embedded parts on the inner mold bottom template, the fixing device for integrated construction of the track beam can firmly install the embedded parts in the predetermined position, especially the installation of special-shaped embedded parts. The protruding ends of the special-shaped embedded parts pass through the installation holes and are firmly fixed on the installation holes, so that the special-shaped embedded parts can be firmly installed on the inner mold bottom template. Compared with conventional linear embedded parts, the special-shaped embedded parts can realize multi-point positioning by fixing multiple protruding ends on the inner mold bottom template at the same time, thereby improving the position accuracy of the embedded parts and the accuracy of the protruding angles of the embedded parts, making the finished product structure more accurate. At the same time, the embedded sections of the special-shaped embedded parts are longer and the structure is more stable. The inner mold can speed up the construction efficiency during the casting of special-shaped casting parts, especially the prefabricated parts that need to have grooves. At this time, if you want to speed up the construction efficiency, most of the methods are secondary casting. The method is to cast once, and then cast the second time when the lower concrete is about to set but has not yet set. However, the construction plan of this situation itself violates the concrete construction specifications and is likely to cause the lower concrete to arch. When pouring the upper part, the concrete pressure acts on the lower concrete in a semi-solidified state, and there is no formwork to provide support, which causes safety hazards. The use of the inner mold and the base mold can complete the concrete pouring construction in one time, which speeds up the construction efficiency and improves the construction quality and construction progress.

[0030] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, proposes a fixing device for integrated construction of track beams, including an inner mold 3, the inner mold 3 includes an inner mold bottom template 303, the inner mold bottom template 303 has an installation hole 301, and the inner mold side template 304 is arranged on the inner mold bottom template 303, and the installation space 302 is surrounded by the inner mold bottom template 303 and the inner mold side template 304.

[0031] In this embodiment, the inner mold 3 is used to open the groove part of the casting part, and the inner mold bottom template 303 is the basic part of the inner mold 3, which has a mounting hole 301 for installing the embedded part 6. The design and size of the bottom template directly determine the shape of the bottom of the prefabricated component and the precise position of the embedded part. The inner mold side template 304 is used to cooperate with the inner mold bottom template 303 to jointly enclose the installation space 302. The side template is set on the inner mold bottom template 303. The main function of the side template is to limit the boundary of concrete pouring and ensure that the side shape and size of the prefabricated component meet the design requirements. The installation space 302 is enclosed by the inner mold bottom template 303 and the inner mold side template 304. This space is used to place the embedded parts and pour concrete. By controlling the position and shape of the inner mold bottom template 303 and the inner mold side template 304, the position of the embedded parts in the concrete can be ensured to be accurate, and the required closed environment is provided for the curing of the concrete. Through the cooperation of the inner mold bottom template 303 and the inner mold side template 304, the fixing device for the integrated construction of the track beam can achieve precise control of the shape and size of the prefabricated components, as well as accurate installation of the embedded parts, which is crucial to improving the construction quality and efficiency of the track beam. Through the rapid installation of the embedded parts on the inner mold bottom template 303, the fixing device for the integrated construction of the track beam can firmly install the embedded parts in the predetermined position, especially the installation of special-shaped embedded parts. The protruding end of the special-shaped embedded part passes through the mounting hole 301 and is firmly fixed on the mounting hole 301, so that the special-shaped embedded part can be firmly installed on the inner mold bottom template 303. Compared with conventional linear embedded parts, the special-shaped embedded parts can achieve multi-point positioning by fixing multiple protruding ends on the inner mold bottom template 303 at the same time, thereby improving the position accuracy of the embedded parts and the accuracy of the protruding angle of the embedded parts, so that the finished product structure has higher accuracy. At the same time, the embedded section of the special-shaped embedded parts is longer and the structure is more stable. The inner mold 3 is more flexible, and the construction efficiency is accelerated during the casting of special-shaped castings, especially for prefabricated parts that need to have grooves. At this time, if you need to speed up the construction efficiency, most of the methods are secondary casting. The method is to cast once, and then cast the second time when the lower concrete is about to set but has not yet set. However, the construction plan of this situation violates the concrete construction specifications and is likely to cause the lower concrete to arch. When pouring the upper part, the concrete pressure acts on the lower concrete in a semi-solidified state, and there is no template to provide support, which causes a safety hazard. The use of the inner mold 3 and the basic mold 1 can complete the concrete casting construction at one time, which speeds up the construction efficiency and improves the construction quality and construction progress.

[0032] Furthermore, it also includes a basic mold 1, which has a grouting cavity 101. The hanging frame 2 is arranged on the basic mold 1 and is located above the grouting cavity 101. The inner mold 3 is arranged on the hanging frame 2 and is located in the grouting cavity 101. The inner mold 3 has a mounting hole 301, and the mounting hole 301 is used to install the embedded part 6. The inner mold 3 also has an installation space 302. The installation space 302 and the grouting cavity 101 are respectively located on both sides of the inner mold 3.

[0033] It includes a basic mold 1, which has a grouting cavity 101. The hanging frame 2 is arranged on the basic mold 1 and is located above the grouting cavity 101. The inner mold 3 is arranged on the hanging frame 2 and is located in the grouting cavity 101. The inner mold 3 has a mounting hole 301, and the mounting hole 301 is used to install the embedded part 6. The inner mold 3 also has an installation space 302. The installation space 302 and the grouting cavity 101 are respectively located on both sides of the inner mold 3.

[0034] In this embodiment, a basic mold is designed. The basic mold is the core component of the entire equipment. It is designed with a grouting cavity for pouring concrete. The shape and size of the grouting cavity directly determine the shape and size of the final prefabricated component. The hanger is set on the basic mold and is located above the grouting cavity, including but not limited to directly above. Its function is to carry and position the inner mold to ensure that the inner mold maintains the correct position during the pouring process. The design of the hanger allows the inner mold to be installed offline before grouting. The design of the hanger makes the installation of the inner mold convenient and fast. The inner mold is set on the hanger and is located inside the grouting cavity. It has mounting holes, which are used to install embedded parts. The embedded parts are usually steel bars, bolts or other metal parts. They become part of the component after the concrete solidifies and are used to connect other structures or equipment. The inner mold is also designed with an installation space. This space and the grouting cavity are located on both sides of the inner mold. Such a design helps to ensure the correct position of the embedded parts in the concrete and provides the necessary space for concrete pouring and curing. Through the synergistic effect of the basic mold, the hanger and the inner mold, the precise forming of the prefabricated components, the accurate installation of the embedded parts, and the efficient control of the concrete pouring process are achieved. By accurately controlling the size of the prefabricated components and the position of the embedded parts, the complexity and uncertainty of the on-site construction can be significantly reduced, the progress of the project can be accelerated, and the safety and durability of the structure can be guaranteed. Compared with the concrete pouring mold of the prior art, especially the pouring of special-shaped castings, if the construction efficiency needs to be accelerated during construction, especially the prefabricated parts that need to be grooved, the method to accelerate the construction efficiency at this time is mostly one-time pouring, and the second pouring is performed when the lower concrete is about to be initially set but has not yet been initially set. However, the construction plan of this situation itself violates the concrete construction specifications, and it is easy to cause the lower concrete to arch. When pouring the upper part, the concrete pressure acts on the lower concrete in a semi-solidified state, and there is no template to provide support, thereby causing safety hazards. The use of the track beam integrated construction fixing device can complete the concrete pouring construction at one time, which speeds up the construction efficiency and improves the construction quality and construction process.

[0035] Furthermore, both sides of the bottom of the inner mold 3 have exhaust gaps 305 , which connect the grouting cavity 101 with the installation space 302 . The exhaust gaps 305 are formed on the inner mold bottom template 303 , or between the inner mold bottom template 303 and the inner mold side template 304 .

[0036] In this embodiment, exhaust gaps 305 are designed on both sides of the bottom of the inner mold 3, and these gaps directly connect the grouting cavity 101 and the installation space 302. Such a design ensures that during the concrete pouring process, air can be smoothly discharged from the installation space 302, avoiding the formation of cavities or bubbles due to air stagnation, which will seriously affect the strength and structural integrity of the concrete. The exhaust gap 305 can be a specific design on the inner mold bottom template 303, or it can be a natural gap between the inner mold bottom template 303 and the inner mold side template 304. The space of the exhaust gap 305 does not allow the discharge of cement mortar, but only allows the discharge of air. Regardless of which design method is used, its purpose is to provide a channel for air circulation to ensure that concrete can fully fill the entire grouting cavity 101 and form a dense and uniform structure. The setting of the exhaust gap 305 has a direct impact on improving the construction quality of the track beam prefabricated components. By effectively removing air, the voids inside the concrete can be significantly reduced, the density of the concrete can be improved, and the strength and durability of the structure can be enhanced. In addition, this also ensures that the concrete around the embedded parts is fully wrapped, and enhances the fixing effect of the embedded parts. By designing the exhaust gap 305 on both sides of the bottom of the inner mold 3, the fixing device for the integrated construction of the track beam can effectively solve the exhaust problem during the concrete pouring process, improve the construction quality and structural performance of the prefabricated components, and enhance the safety and service life of the cast parts. Compared with the casting mold of the prior art, the design of the exhaust gap 305 solves the problem that the gas in the concave and convex parts of the special-shaped casting parts cannot be completely discharged during the casting, thereby affecting the casting efficiency and casting effect. In summary, the exhaust gap 305 solves the problem of incomplete exhaust of bubbles during the tamping and vibration process after casting.

[0037] Furthermore, both sides of the inner mold bottom template 303 have first arc-shaped portions 306 , and the lower end of the inner mold side template 304 has a second arc-shaped portion 307 . The first arc-shaped portion 306 and the second arc-shaped portion 307 overlap with each other to form an exhaust gap 305 .

[0038] In this embodiment, the two sides of the inner mold bottom template 303 are designed with a first arc portion 306, and the lower end of the inner mold side template 304 is provided with a second arc portion 307. The design of these two arc portions not only takes into account the aesthetics and practicality of the structure, but more importantly, they can naturally form an exhaust gap 305 when they overlap each other. When the first arc portion 306 and the second arc portion 307 overlap, the tiny gap between them constitutes the exhaust gap 305. This design ensures that during the concrete pouring process, air can be smoothly discharged from the installation space 302 through the exhaust gap 305, preventing the formation of bubbles, thereby improving the density and structural strength of the concrete. Through the ingenious design of the first arc portion 306 and the second arc portion 307, the fixture for integrated construction of the track beam can effectively solve the exhaust problem during the concrete pouring process, avoid concrete structural defects caused by air stagnation, and ensure the quality of the prefabricated components. Compared with other structures, the design of the arc portion makes the exhaust gap 305 also arc-shaped, and the arc-shaped exhaust gap 305 allows bubbles to be discharged from the exhaust gap 305 more smoothly when reaching the exhaust gap 305. In addition, this design also helps to improve construction efficiency and reduce repetitive work and material waste caused by poor exhaust. The design of the arc portion not only solves the exhaust problem, but also has a beneficial effect on the stability of the structure and construction safety. The arc edge is less prone to damage than the right-angle edge, thereby improving the service life of the inner mold 3 and the quality of the cast finished product. In addition, the arc edge also reduces the turbulence when the concrete is poured through the bottom of the inner mold 3, reduces the impact force of the concrete on the inner mold 3, and improves the safety of the construction process. By designing the first arc portion 306 and the second arc portion 307 on the inner mold bottom template 303 and the inner mold side template 304, the track beam integrated construction fixing device not only ensures the construction quality, but also improves the safety of the structure and construction.

[0039] Furthermore, the inner mold side template 304 is raised or lowered relative to the inner mold bottom template 303 , and after the inner mold side template 304 is raised or lowered, the exhaust gap 305 is expanded or reduced.

[0040] In this embodiment, the inner mold side template 304 can be raised and lowered relative to the inner mold bottom template 303, and the construction personnel can adjust the height of the side template according to the actual situation before or during the concrete pouring. This design provides higher flexibility to adapt to concrete layers of different thicknesses or specific construction requirements. As the inner mold side template 304 is raised and lowered, the size of the exhaust gap 305 will also expand or shrink accordingly. In the early stage of concrete pouring, a larger exhaust gap 305 may be required to quickly exhaust a large amount of air; while in the later stage of pouring, a smaller gap helps prevent concrete loss and ensure that the last bit of air can be effectively exhausted. This adjustable exhaust gap 305 design helps to optimize the concrete pouring process, reduce air stagnation, and improve the density and structural strength of concrete. At the same time, it can also reduce concrete waste, improve construction efficiency, and ensure the consistency of construction quality. The liftable design of the inner mold side template 304 increases the flexibility of construction, enables the same set of equipment to adapt to prefabricated components of different sizes, reduces the need for special molds, and thus reduces costs. At the same time, this design can also reduce pauses and waiting time during construction and improve overall construction efficiency. Through the lifting mechanism of the inner mold side template 304 relative to the inner mold bottom template 303, the fixing device for integrated construction of the track beam can not only effectively control the size of the exhaust gap 305, but also improve the flexibility of construction.

[0041] Furthermore, the inner mold bottom template 303 has a plurality of high-pressure air holes 308 arranged in sequence, the high-pressure air holes 308 connect the grouting cavity 101 with the installation space 302, and also include a sealing film 4, which is arranged on the inner mold bottom template 303 and the inner mold side template 304 facing the grouting cavity 101.

[0042] In this embodiment, the high-pressure air holes 308 on the inner mold bottom template 303 are arranged in sequence, and these air holes directly connect the grouting cavity 101 and the installation space 302. After the concrete pouring is completed, the grouting template and the cement finished product can be quickly separated by injecting high-pressure gas into the high-pressure air holes 308. The sealing film 4 is arranged on the side of the inner mold bottom template 303 and the inner mold side template 304 facing the grouting cavity 101. Its main function is to prevent the concrete from leaking during the pouring process, and at the same time, it can also prevent external impurities from entering and keep the concrete pouring environment clean. In addition, the sealing film 4 can also play an isolating role, avoiding the sticking phenomenon caused by the direct contact between the inner mold 3 and the concrete, and facilitating demoulding. The combined use of the high-pressure air holes 308 and the sealing film 4 significantly improves the construction quality of the track beam prefabricated components. The sealing film 4 ensures the neatness and smooth progress of the concrete pouring process, reducing the material waste and post-processing work during the construction process. The sealing film 4 prevents concrete leakage, and the entire concrete pouring process is more efficient and orderly. In addition, reducing material waste and improving construction quality will also help reduce the total cost of the project and improve economic benefits in the long run. Through the arrangement of the high-pressure air holes 308 and the sealing film 4 on the inner mold bottom template 303, the track beam integrated construction fixture not only optimizes the concrete pouring process and improves the construction quality, but also reduces the labor intensity of the construction workers.

[0043] Furthermore, the inner mold bottom template 303 has a first guide surface 309, which gradually tilts upward to the exhaust gap 305. There are two first guide surfaces 309 symmetrical to each other, which are used to guide the bubbles in the grouting cavity 101 to the exhaust gaps 305 on both sides of the inner mold bottom template 303.

[0044] In this embodiment, the first guide surface 309 on the inner mold bottom template 303 is designed to gradually tilt upward to the exhaust gap 305, and there are two mutually symmetrical ones. The purpose of this design is to guide the bubbles in the grouting cavity 101 to move to the exhaust gaps 305 on both sides, and discharge through the exhaust gaps 305 to prevent the bubbles from gathering inside the concrete and affecting the structural strength and density. During the concrete pouring process, due to the stirring and pouring actions, a certain amount of air will be contained inside the concrete to form bubbles. The inclined design of the first guide surface 309 uses the fluidity of the concrete itself to guide the bubbles to the exhaust gap 305, ensuring that the bubbles can be discharged smoothly instead of being retained inside the concrete. At the same time, during the tamping process after the pouring is completed, the bubbles float to the first guide surface 309 and are guided to the exhaust gap 305 through the first guide surface 309. Through the design of the first guide surface 309, the fixing device for the integrated construction of the track beam can effectively reduce the formation of bubbles inside the concrete and improve the compactness and strength of the concrete structure. This is crucial to ensure the quality and durability of the track beam prefabricated components, especially for rail transit facilities that are subject to heavy loads and complex environmental conditions. Reducing bubbles inside concrete can not only improve the mechanical properties of the structure, but also reduce the cost of subsequent maintenance and repair. In addition, by optimizing the exhaust process, the concrete pouring time can be shortened, the construction efficiency can be improved, and the cost can be reduced overall. Through the design of the first guide surface 309 on the inner mold bottom template 303, the track beam integrated construction fixture can more effectively control the discharge of bubbles during the concrete pouring process to ensure the quality of the prefabricated components.

[0045] Furthermore, the mounting hole 301 is a tapered hole and further comprises a tapered nut 5 . The tapered nut 5 is placed upside down in the tapered hole, and the mounting embedded part 6 is threadedly connected to the tapered nut 5 .

[0046] In this embodiment, the mounting hole 301 on the inner mold bottom template 303 is designed as a tapered hole, which has better positioning and guiding functions than the traditional circular hole. The tapered hole can more accurately guide the embedded part into the hole, avoid displacement during the installation process, and ensure that the installation position of the embedded part is accurate. The tapered nut 5 is designed to be placed upside down in the tapered hole, and it is connected to the embedded part by a thread. The design of the tapered nut 5 matches the tapered hole, can fit the hole wall more closely, reduce the displacement risk of the embedded part during the concrete pouring process, and improve the fixing strength and stability of the embedded part. Through the use of the tapered hole and the tapered nut 5, the embedded part can be more accurately positioned and more firmly fixed during the installation process. This not only improves the installation accuracy of the embedded part, but also ensures the good combination of the embedded part and the concrete structure, and improves the structural integrity and safety of the track beam prefabricated component. The design of the tapered hole and the tapered nut 5 simplifies the installation process of the embedded part, reduces the installation error, and thus improves the construction efficiency. At the same time, due to the precise installation of the embedded parts, the need for later adjustment and repair is reduced, the construction cost is reduced, and the overall economic benefits of the project are improved. Through the design of the tapered hole on the inner mold bottom template 303 and the matching tapered nut 5, the track beam integrated construction fixing device can more accurately control the position of the embedded parts during the installation of the embedded parts to ensure their stability.
