Description

Technical Field

[0001] This utility model belongs to the field of pipeline installation technology in municipal pipeline engineering, specifically relating to standardized templates used in the construction of concrete foundations for municipal pipelines. Background Technology

[0002] In municipal pipeline engineering, concrete foundations are commonly used for concrete pipes and reinforced concrete pipes, with 120° concrete foundations being particularly prevalent. Currently, during the construction of such foundations, the formwork erection process mostly uses wooden formwork as side formwork. The formwork is fixed by adding ground nails on the outside, and square timber is used to tighten the side formwork at one end and support the ground or trench sidewall at the other end to resist the lateral pressure during concrete pouring. Although some projects use steel formwork as side formwork, the method of fixing the side formwork is basically the same as that of wooden formwork.

[0003] However, the existing process has obvious defects: both the ground nails and the square timber only bear lateral pressure on the outside of the formwork, and the inside of the formwork cannot be effectively tied due to the obstruction of pipes; the square timber needs to be assembled and fixed in multiple ways, and in narrow areas, it also needs to be directly supported against the sidewall of the trench. If the ground or the sidewall of the trench is soil, it is easy to cause the formwork to run away due to unreliable fixing; at the same time, the square timber support process consumes a lot of manpower, and the operation is time-consuming and labor-intensive, which seriously affects the construction efficiency and the quality of foundation construction. Therefore, there is an urgent need for a formwork solution that can solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a standardized template for concrete foundations of municipal pipelines to solve the problems existing in the prior art. This template can be quickly positioned without complicated measurements, is easy to assemble and disassemble, is reusable and adaptable to various pipe diameters, can improve the quality of concrete pouring, and save labor and time costs. It is suitable for the construction of concrete foundations for municipal pipeline projects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a standardized formwork for concrete foundations of municipal pipelines, comprising: Side formwork symmetrically placed on both sides of the pipe is used to limit the forming range of the concrete foundation; Pipe connectors adapted to pipes, wherein the pipe connectors are snapped onto the outer periphery of the pipes and are detachably connected to the side templates on both sides; Fastening components are used to lock the relative position of the pipe connector and the side formwork to provide a tethering force to prevent the side formwork from overturning under the pouring load; And fasteners, which are inserted into the bottom of the side template, are used to fix the side template to the ground to achieve overall stability.

[0006] To further optimize this utility model, the following technical solutions may be preferred: Preferably, the side formwork is made of metal, and the height of the side formwork is adapted to the construction requirements of concrete foundations for pipes with the largest pipe diameter and below commonly used pipe diameters.

[0007] Preferably, each pipe section is equipped with at least two pipe connectors, which are spaced apart along the pipe axis.

[0008] Preferably, the pipe connector includes a curved section that fits against the outer periphery of the pipe, and an extended section that extends to both sides, wherein the extended section is provided with a connection structure that cooperates with the fastening assembly.

[0009] Preferably, the fastening assembly includes a screw and a nut. The screw is located on the extended section of the pipe connector. The side template has a screw hole adapted to the screw. The screw passes through the screw hole and is locked and fixed by the nut.

[0010] Preferably, the fixing element is a ground nail, and the bottom of the side template has nail holes for the ground nail to pass through, and the ground nail is driven into the ground to fix the side template.

[0011] Preferably, the length of the extended section of the pipe connector is customized according to the design width of the concrete foundation corresponding to different pipe diameters, so as to adapt to the construction needs of pipes of various diameters.

[0012] Preferably, each pipe section is equipped with three pipe connectors, and the three pipe connectors are evenly distributed along the pipe axis.

[0013] This utility model addresses the shortcomings of existing municipal pipeline concrete foundation formwork erection processes by providing a standardized formwork for municipal pipeline concrete foundations, which has the following significant advantages: (1) Solve the problem of unstable fixing of existing templates: By connecting the pipe connectors to the side templates in a detachable manner, and using fastening components to provide tension, the side templates are fixed to the ground with the fasteners, forming a stable structure with internal and external coordination. This effectively avoids the phenomenon of template running away due to only external support in soil layers or narrow areas, and ensures the quality of foundation construction.

[0014] (2) Significantly improve construction efficiency: The pipe connectors are compatible with the pipe design, and the side formwork can be quickly positioned without complicated measurement and layout. The fastening components and fasteners are easy to operate, simplifying the traditional multi-stage assembly process, significantly shortening the formwork support and dismantling time, and reducing labor consumption.

[0015] (3) Strong versatility and economy: The side formwork is compatible with the most common pipe diameter and below. With special pipe connectors for different pipe diameters, it can meet the construction needs of various pipe diameters. The formwork can be reused, reducing material consumption and saving project costs. It is suitable for large-scale municipal pipeline network projects. Attached Figure Description

[0026] As a preferred implementation, the length of the pipe connector's extension is customized according to the design width of the concrete foundation corresponding to different pipe diameters, in order to adapt to the construction needs of pipes of various diameters.

[0027] As a preferred embodiment, each pipe section is equipped with three pipe connectors, which are evenly distributed along the pipe axis.

[0028] This utility model is applicable to the construction of concrete foundations for concrete pipes and reinforced concrete pipes (especially suitable for 120° concrete foundations) in municipal pipeline network projects. The following describes the municipal pipeline concrete foundation template of this utility model in detail with specific construction scenarios.

[0029] In this embodiment, a U-shaped cement pad is designed below the reinforced concrete pipe, and the side formwork is made of steel side plate (i.e., steel side plate). Its height is determined with reference to the maximum pipe diameter among commonly used pipe diameters and the corresponding concrete foundation design requirements, which can adapt to the construction needs of all medium and small pipe diameters below the maximum pipe diameter; the pipe connector is a steel pipe clamp adapted to the pipe diameter, and each standard pipe section is equipped with 3 steel pipe clamps, which are evenly spaced along the pipe axis; the fastening component includes a screw rod integrated on the extended section of the steel pipe clamp, and a nut adapted to the screw rod, and a screw hole matching the screw rod is opened on the steel side plate; the fixing component is a steel fixing nail, and a nail hole for the fixing nail to pass through is opened at the bottom of the steel side plate.

[0030] The specific construction steps are as follows: 1. Pipe fitting installation: After the pipe (such as a reinforced concrete pipe) is installed in place, select the appropriate steel pipe clamp according to the current pipe diameter, and clamp the three steel pipe clamps to the preset axial position on the outer circumference of the pipe respectively, ensuring that the bent section of the steel pipe clamp fits tightly against the outer wall of the pipe.

[0031] 2. Assembly of side formwork and fastening components: Place the two steel side plates on both sides of the pipe respectively, adjust the position of the steel side plates so that the screw holes on the steel side plates correspond one-to-one with the screws on the extended section of the steel pipe clamp, push the steel side plates so that the 6 screws (3 on each side of the steel pipe clamp) pass through the corresponding screw holes, and then put a nut on the end of each screw and tighten the nut with a tool to fix the steel side plate to the steel pipe clamp. At this time, the nut and the screw provide a tensile force for the steel side plate to prevent it from turning over under the subsequent pouring load.

[0032] 3. Side formwork fixing: Take the fixing nails, align them with the nail holes at the bottom of the steel side plate, and hammer the top of the fixing nails to drive them vertically into the ground. Fixing nails are set at intervals along the length of each steel side plate to ensure the overall stability of the steel side plate. The formwork installation is now complete.

[0033] 4. After the concrete pouring in the concrete pouring area 6 is completed and the strength meets the design requirements, first remove all the fixing nails with tools, then unscrew the nuts, separate the bolts from the steel side plates, and finally remove the steel side plates and steel pipe clamps, and transfer them to the next construction section for reuse.

[0034] This specific embodiment is only a preferred embodiment of the present utility model and is not a limitation on the protection scope of the present utility model. Any improvement or replacement by conventional technical means under the design concept of the present utility model shall fall within the protection scope of the present utility model.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
