Description

Technical Field

[0001] The utility model relates to the technical field of pre-buried grooves, in particular to a pre-buried groove with an anti-deformation effect. Background Art

[0002] Embedded channels, also known as trough-type embedded parts, are connectors that are fixed in concrete by embedding. Compared with traditional concrete embedding and anchoring technology, embedded troughs can avoid structural damage to the pipe segments caused by drilling, and can also improve the installation quality and installation, and improve the working environment of electromechanical installation.

[0003] When casting in situ or prefabricated concrete subway walls, embedded grooves are often used as bearing anchor points on the subway tunnel walls. When making subway walls, the concrete is usually poured after the steel mesh is filled in the prefabricated wall formwork. The embedded grooves are usually attached to the inside of the formwork, so that the embedded grooves are wrapped when the concrete is poured again. After solidification, the formwork is removed, and the embedded grooves are fixed in the concrete. Since the embedded grooves themselves will produce certain deformations, when pouring concrete, it is not only easy to cause deformation of the embedded grooves, but also a certain impact force will be generated, causing the embedded grooves to shift in position, thus affecting subsequent use. Utility Model Content

[0004] The purpose of the utility model is to provide a pre-buried channel with an anti-deformation effect to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: an embedded channel with anti-deformation effect, comprising an embedded channel body and a plurality of anchor bolts welded on the back thereof, and also comprising:

[0006] A plurality of support blocks movably connected to the interior of the embedded channel body, wherein the surfaces of the support blocks are fixedly connected with fixing rods;

[0007] A concave plate is fixed on both sides of the bottom of the embedded channel body, and the inner side of the concave plate is rotatably connected to a support plate, the other end of the support plate is internally movably connected to a movable plate, the other end of the movable plate is fixedly connected to an arc plate, and the bottom of one end of the support plate is threadedly connected to a fixing bolt for fastening the movable plate and the support plate.

[0008] Preferably, a slide groove is provided on one side of the support plate, a sliding block is fixedly connected to the top of the movable plate, and a surface of the sliding block is slidably connected to the inside of the slide groove.

[0009] Preferably, a middle position of the bottom of the embedded channel body is rotatably connected to a limit cam, and the tops of both ends of the limit cam fit with the inner side of the arc plate.

[0010] Preferably, the surface of the movable plate is provided with scale markings, and the length of the scale markings is the same as the length of the movable plate.

[0011] Preferably, fastening holes are provided on both sides of the back side of the embedded channel body.

[0012] Preferably, the other end of the fixing rod is fixedly connected to a force applying rod, and the surface of the force applying rod is surrounded by a plurality of anti-slip patterns.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model is provided with a plurality of support blocks through the internal movable connection of the embedded channel body. When the embedded channel body is cast, the inner side of the embedded channel body can be supported to prevent the notch inside the embedded channel body from being deformed. At the same time, through the rotation connection between the support plate and the concave plate, the arc plate can be clamped on the steel bars on the steel mesh, thereby facilitating the support of the embedded channel body and preventing the deviation during casting.

The surface of the slider 13 is slidably connected to the inside of the slide groove 12, so that the moving distance of the movable plate 8 inside the support plate 7 can be limited to prevent it from falling off from the inside of the support plate 7.

[0023] The middle position at the bottom of the embedded channel body 1 is rotatably connected to the limit cam 15, and the tops of the two ends of the limit cam 15 are in contact with the inner side of the arc plate 9, so that the support plate 7, the movable plate 8 and the arc plate 9 closed on the bottom surface of the embedded channel body 1 can be limited to prevent them from being rotated at will when not in use.
