Description

Technical Field

[0001] The utility model belongs to the field of embedded channels, and particularly relates to an embedded channel which is convenient for installation. Background Technique

[0002] The embedded channel is a common connector in bridge and tunnel projects, and is used to connect equipment such as pipelines and lines to the surface of a concrete wall. Through the embedded process, the later installation project will not damage the concrete structure poured in the early stage, and it is a very practical construction technology and facility. At present, in the use of the embedded rod of the channel, the friction between its smooth surface and the concrete is small. Although one end has a relatively wide limiting piece, the fastening force still needs to be improved.

[0003] At present, the Chinese utility model with the publication number of CN209671004U discloses an embedded channel which is convenient for installation, and relates to the technical field of building connectors. The embedded channel which is convenient for installation includes a channel body and a T-shaped screw rod. One end of a spring piece is fixedly connected to the top of the inner wall of the channel body, and the other end of the spring piece is fixedly connected to the upper surface of a gasket. The two ends of the gasket are provided with upwardly bent flanks. A first through hole is arranged on the surface of the spring piece corresponding to the position of the gasket, a second through hole is arranged on the surface of the spring piece corresponding to the top of the inner wall of the channel body, a through hole is arranged on the gasket corresponding to the second through hole, and the screw cap of the T-shaped screw rod is movably connected to the lower surface of the gasket and the bottom of the inner wall of the channel body. The utility model solves the problems that the screw rod is easy to shake during the construction process and the moving friction of the screw rod with a rubber pad is large, resulting in inconvenient installation of equipment on the screw rod by arranging the spring piece, the gasket and the flanks.

[0004] During the use of this embedded channel, it is necessary to tighten the nut on the T-shaped screw rod. During the tightening of the nut, it is necessary to first ensure that the T-shaped screw rod does not rotate, otherwise the situation that one end of the T-shaped screw rod appears in a horizontal state and falls off the channel will occur. However, there are inconveniences in the fixation of the current T-shaped screw rod. This embedded channel can only limit the position of the T-shaped screw rod, but cannot fix the angle of the T-shaped screw rod. Content of the Utility Model

[0005] The purpose of the utility model is to provide an embedded channel which is convenient for installation, and its advantages are to effectively increase the anti-pulling effect of the embedded channel, improve the stability of subsequent use, avoid the rotation of the nut affecting the screw rod, and be more conducive to the operation and installation of the operator.

[0006] The above technical object of the utility model is achieved by the following technical solutions: a pre-embedded channel which is convenient to install, comprising a U-shaped groove, a pre-embedded rod is fixedly installed at the rear side of the U-shaped groove, a collar is fixedly sleeved on the surface of the pre-embedded rod, an end block is fixedly installed at one end of the pre-embedded rod, an outer block is fixedly installed on the surface of the end block, elastic sheets are arranged at both ends inside the U-shaped groove, a contact sheet is fixedly installed at one end of each elastic sheet, a contact plate is fixedly installed between the two contact sheets, a block is arranged on the surface of the contact plate, a screw rod penetrating through the surface of the U-shaped groove is fixedly installed on one side of the block, a first clamping convex block is fixedly installed on the surface of the contact plate, a second clamping convex block is fixedly installed on the other side of the block, the first clamping convex block and the second clamping convex block are clamped and matched with each other, and both the first clamping convex block and the second clamping convex block are horizontally arranged.

[0007] Adopting the above technical solutions: when installing the pre-embedded channel, the operator fills the U-shaped groove with foam by the current conventional technology to prevent concrete from entering the U-shaped groove during concrete pouring. The foam will be present between the contact plate and the U-shaped groove and is blocked at both ends of the U-shaped groove. During the concrete pouring and embedding, the pre-embedded rod is in the concrete. Among them, through the evenly distributed collars, the friction between the pre-embedded rod and the concrete surface is increased, and the outer block increases the surface area of the end block to facilitate increasing the anti-pulling effect in subsequent use. Through this setting, the anti-pulling effect of the pre-embedded channel can be effectively increased, and the stability of subsequent use can be improved. At the same time, during the use of the pre-embedded channel, the operator places the block in the U-shaped groove in the horizontal state. At this time, the first clamping convex block is in the horizontal state, while the second clamping convex block is in the vertical state, and the first clamping convex block and the second clamping convex block are not clamped with each other. Subsequently, the operator rotates the block and the screw rod to make the block in the vertical state, as shown in the accompanying drawings of the specification. At this time, the first clamping convex block and the second clamping convex block are clamped with each other, and the elastic sheet always squeezes the block between the contact plate and the U-shaped groove to help the block achieve fixation. When the position of the block needs to be adjusted, the operator gently pushes the screw rod towards the contact plate, so that the block squeezes the elastic sheet. After there is a gap between the block and the U-shaped groove, the block can be moved. The horizontal arrangement of the first clamping convex block and the second clamping convex block facilitates the horizontal movement of the block on one side of the contact plate. When it is necessary to install an external structure by contacting the pre-embedded channel and it is necessary to tighten a nut on the surface of the screw rod, while the elastic sheet squeezes the block, the first clamping convex block and the second clamping convex block help the block maintain the vertical state, preventing the rotation of the nut from affecting the screw rod. And this structure is different from the existing support and fixation of the screw rod during nut tightening, which is more conducive to the operator's operation and installation.

[0008] The utility model is further arranged such that the number of the collars is four, and they are evenly distributed on the surface of the pre-embedded rod at equal intervals.

[0009] Adopt the above technical solution: By means of the evenly distributed collar rings, the friction force on the surface of the embedded rod is increased.

[0010] The present utility model is further configured such that the number of the outer blocks is four, and they are evenly distributed on the surface of the end block in a circumferential manner.

[0011] Adopt the above technical solution: By means of the outer blocks, the surface area of the end block is increased, so as to increase the anti-pulling effect during subsequent use.

[0012] The present utility model is further configured such that a fixing piece is fixedly installed at the other end of the elastic piece, and the fixing piece is fixedly installed with the inner side of the U-shaped groove.

[0013] Adopt the above technical solution: The elastic piece is firmly fixed with the U-shaped groove through the fixing piece.

[0014] The present utility model is further configured such that arc-shaped ends are formed at both ends of the contact plate.

[0015] Adopt the above technical solution: The arc-shaped ends facilitate the movement of the block, and facilitate the movement of the block between the contact plates when multiple U-shaped grooves are spliced.

[0016] In summary, the present utility model has the following beneficial effects:

[0017] 1. When the present utility model installs the embedded channel, during the casting and embedding of concrete, the embedded rod is in the concrete. Among them, through the evenly distributed collar rings, the friction between the embedded rod and the concrete surface is increased, and the outer blocks increase the surface area of the end block, so as to increase the anti-pulling effect during subsequent use. Through this setting, the anti-pulling effect of the embedded channel can be effectively increased, and the stability of subsequent use can be improved;

[0018] 2. When the present utility model uses the embedded channel, the operator places the block in the U-shaped groove in the horizontal state, and then the operator rotates the block and the screw rod so that the block is in the vertical state. At this time, the first clamping convex block and the second clamping convex block are clamped with each other, and the elastic piece always squeezes the block between the contact plate and the U-shaped groove to help the block achieve fixation. When it is necessary to tighten the nut on the surface of the screw rod, while the elastic piece squeezes the block, the first clamping convex block and the second clamping convex block help the block maintain the vertical state, preventing the rotation of the nut from affecting the screw rod, and this structure is different from the existing support and fixation of the screw rod during nut tightening, which is more conducive to the operation and installation of the operator.

When the position of the block 11 needs to be adjusted, the operator gently pushes the screw 12 towards the contact plate 9, so that the block 11 squeezes the elastic piece 6. After there is a gap between the block 11 and the U-shaped groove 1, the block 11 can be moved. The horizontal arrangement of the snap bump one 13 and the snap bump two 14 facilitates the horizontal movement of the block 11 on one side of the contact plate 9.
