Description
Technical Field
[0001] The utility model belongs to the technical field of concrete embedded channels, and particularly relates to a device for installing and fixing embedded channels in cast-in-place concrete structures. Background Technique
[0002] As an important part of modern urban infrastructure, the underground urban utility tunnel integrates various pipelines such as power, communication, water supply, and drainage, and is the "lifeline" to ensure the normal operation of the city. In such a utility tunnel, the embedded channel is the core component of the pipeline support inside the tunnel, and its installation quality is directly related to the stability and safety of the entire tunnel system.
[0003] An effective installation method is crucial for ensuring the quality of the embedded channel. Professional installation tools and techniques are required to ensure the horizontal and verticality of the channel and avoid deviations. The fixing method of the channel can ensure that the channel will not shift or deform during the concrete pouring process.
[0004] At present, for the embedded channel in the cast-in-place concrete structure, in the traditional construction process, the embedded channel is fixed to the structural steel bars for the cast-in-place structure. During the concrete pouring process, there are problems such as the embedded channel not being closely attached to the side wall formwork, resulting in too large a concrete cover for the embedded part; the impact of the concrete pouring on the concrete causes deformation and displacement of the embedded channel. Before installing the pipeline support, artificial chiseling is required due to too large a concrete cover or re-embedding is required due to the deviation of the embedded channel. Content of the Utility Model
[0005] The purpose of the utility model is to overcome the problems existing in the existing concrete pouring process, such as the embedded channel not being closely attached to the side wall formwork, resulting in too large a concrete cover for the embedded part; the impact of the concrete pouring on the concrete causes deformation and displacement of the embedded channel, and provides a device for installing and fixing the embedded channel in the cast-in-place concrete structure.
[0006] The utility model is applicable to various types of construction projects, especially for projects that require high-precision embedded channels, and has significant advantages. By simplifying the construction process and improving the construction quality, the utility model is expected to be widely applied and promoted in the construction industry.
[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0008] A device for installing and fixing an embedded channel in a cast-in-place concrete structure includes a side wall formwork, an embedded channel component, and a U-shaped buckle. The embedded channel component is fixed on the facade of the main structure, the U-shaped buckle covers the outer side of the embedded channel component, and the side wall formwork is installed in contact with the embedded channel component and the U-shaped buckle.
[0009] The embedded channel component is of a T-shaped structure.
[0010] Pour cast-in-place concrete into the interior of the facade of the main body structure and outside the U-shaped buckle to form a cast-in-place concrete structure.
[0011] The U-shaped buckle covers the channel embedded part, forming a hollow structure inside the channel embedded part.
[0012] When the side wall formwork is installed, it maintains verticality.
[0013] First reserved holes are provided on the two horizontal sides of the U-shaped buckle, and second reserved holes are provided at both ends of the side wall formwork.
[0014] The positions of the reserved holes on the U-shaped buckle and the side wall formwork correspond, and the hole diameters are the same.
[0015] It includes bolts. The bolts are located outside the side wall formwork and pass through the first reserved hole and the second.
[0016] It includes nuts, and the nuts fix the bolts.
[0017] The bolts are driven into the interior of the cast-in-place concrete structure.
[0018] Compared with the prior art, the utility model has the following beneficial effects:
[0019] The utility model provides a device for installing and fixing embedded channels in a cast-in-place concrete structure, including a side wall formwork, a channel embedded part, and a U-shaped buckle. The channel embedded part is fixed on the facade of the main body structure, the U-shaped buckle covers the outer side of the channel embedded part, and the side wall formwork is installed in contact with the channel embedded part and the U-shaped buckle. Using the principle of complementary shapes, the shape of the U-shaped buckle can form a tight fit with the channel embedded part, forming a hollow structure between the channel embedded part and the side wall formwork, which can ensure that the embedded part will not be displaced due to the impact force during the concrete pouring process, enhancing stability. This device has the advantages of simple structure, convenient installation, stable fixation, etc., can effectively improve the construction quality and efficiency, reduce the construction cost, and has strong practical value at the same time.
[0020] Furthermore, by marking, drilling, connecting with bolts, and fastening with nuts for the U-shaped buckle, the installation of the device can be completed. This installation method not only simplifies the construction process but also improves the construction efficiency.
[0021] Furthermore, the design of this device is based on mechanical principles. Through the fastening action of bolts and nuts, sufficient friction force is generated to enable the channel embedded part to withstand the impact force from the concrete during the concrete pouring process. This design ensures the stability and firmness of the channel embedded part.
[0022] Furthermore, the design of the buckle can be processed according to the size of the channel part, and it can adapt to channel embedded parts of different sizes and shapes, improving the versatility and applicability of the product. Brief Description of the Drawings

[0026] To further understand the content of the present utility model, the following describes the present utility model in detail with reference to the drawings and specific embodiments. It should be understood that the embodiments are only for explaining the present utility model rather than limiting it.
[0027] A device for installing and fixing embedded channels in a cast-in-place concrete structure, the structure and usage process of which are as follows:
[0028] As Figures 1 - 2 shown, a device for installing and fixing embedded channels in a cast-in-place concrete structure includes a side wall formwork 1, a channel embedded part 5 and a "J"-shaped buckle 2. The channel embedded part 5 is of a T-shaped structure and is fixed on the vertical surface of the main structure. The "J"-shaped buckle 2 is placed upside down to cover the outer side surface of the channel embedded part 5. The protruding side of the "J"-shaped buckle 2 is attached to the channel embedded part 5, and the horizontal side is attached to the side wall formwork 1, fixing the channel embedded part 5 on the side wall formwork 1 and forming a hollow structure between the channel embedded part 5 and the side wall formwork 1. Second reserved holes 8 are opened at both ends of the side wall formwork 1, and first reserved holes 7 are opened on both horizontal sides of the "J"-shaped buckle 2, corresponding to the positions of the second reserved holes 8 on the side wall formwork 1 and having the same aperture size. The bolt 3 is passed through the side wall formwork 1 and driven into the cast-in-place concrete structure 6 from the reserved holes, and fixed with nuts 4. Through the cooperation with the bolt 3, the stable fixation of the channel embedded part 5 is achieved.
[0029] Furthermore, when installing the side wall formwork 1, ensure that the side wall formwork 1 is kept vertical, which can be achieved by using tools such as a spirit level and a laser distance meter.
[0030] Preferably, as another technical solution of the present utility model, by optimizing the channel, bolt holes are reserved in the channel. The bolt and the gasket pass through the channel and the formwork through the reserved holes, and then are fixed by tightening nuts and gaskets.
[0031] It should be noted that before the concrete pouring, in order to ensure the stable position of the channel in the side wall formwork 1, additional fixing measures can be adopted. For example, special fixtures or tie rods are used to tightly connect the channel with the side wall formwork or structural steel bars to prevent it from moving due to the force generated by the flowing concrete during the pouring process. At the same time, in order to ensure that the function of the channel is not affected during subsequent use, it needs to be properly protected during the concrete pouring and curing processes. This includes filling the internal chute of the channel with foaming material to prevent concrete or slurry from entering and blocking the chute of the channel.
[0032] After the concrete pouring is completed, the quality inspection of the position and state of the channel needs to be carried out. This can be achieved by using measuring tools (such as a spirit level, a tape measure, etc.) to check whether the channel meets the design requirements. If position deviation or damage is found, timely adjustment or replacement is required.
[0033] When the concrete reaches sufficient strength, the side wall formwork 1 can be removed. During the removal process, special care needs to be taken to avoid damaging the channel. After the side wall formwork is removed, then the bolt 3 is loosened, and the bolt 3 can be taken out by rotating the nut 4. The nut is a consumable and does not need to be taken out. The U-shaped buckle 2 and the nut 4 can be reused.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: modifications or equivalent replacements can still be made to the specific implementation manners of the present invention, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention shall be covered within the protection scope of the claims of the present invention.
