Description

Technical Field

[0001] The present application relates to the field of construction engineering, and in particular to a conveniently assembled embedded channel. Background Art

[0002] Embedded channel is a prefabricated component widely used in the field of construction and engineering, mainly used in concrete structures. It is a steel or plastic trough-shaped component pre-installed in the formwork before concrete pouring, and is used to fix various structural components in the later stage, such as pipes, cables, steel bars, etc. The use of embedded channel can improve the integrity and durability of the structure, while simplifying the construction process and reducing the later excavation and drilling work.

[0003] The embedded channel usually includes a channel body and an anchor rod. The channel body is provided with a slot along the length direction and has a C-shaped cross-section. The anchor rod is fixedly connected to the channel body. The anchor rod and the channel body are cast in concrete together. The anchor rod is anchored in the concrete structure to fix the channel body. Bolts are usually provided in the slot of the channel body. The screw head of the bolt is located in the slot, and the screw rod of the bolt extends from the slot for connecting other components.

[0004] During on-site construction, it is usually necessary to weld multiple anchor rods to the channel body one by one to form an anchoring effect on the channel body. However, welding anchor rods one by one is very cumbersome, which makes the implementation process inconvenient and slows down the on-site construction process. Some construction processes will pre-weld the channel body and anchor rods before transporting them to the construction site. However, the pre-fixed anchor rods may conflict with the steel bars in the concrete structure, causing inconvenience in implementation. Utility Model Content

[0005] In order to improve the convenience of implementing the embedded groove, the present application provides a convenient assembled embedded groove, which has the advantages of convenient installation, adjustable anchor position and strong applicability.

[0006] The present application provides a convenient assembled embedded channel adopting the following technical solution:

[0007] A convenient assembled embedded channel comprises a channel body, a plurality of anchor rods and a plurality of bolts, wherein the plurality of bolts are arranged in a slot of the channel body, a mounting track is formed on a side of the channel body away from the slot, the anchor rods have a sliding end and an anchoring end, the sliding ends of the plurality of anchor rods are slidably arranged in the mounting track, a clamping structure is arranged between the sliding ends of the plurality of anchor rods and the mounting track, and the clamping structure is used to fix the position of the anchor rods in the mounting track.

[0008] By adopting the above technical solution, multiple anchor rods can be quickly installed and fixed by using the installation track and the clamping structure, which effectively improves the implementation efficiency compared to welding the anchor rods and the channel body. Moreover, the position of the anchor rod on the channel body can be adjusted. In the subsequent construction process, if the position of the anchor rod needs to be adjusted, the position of the anchor rod can be changed by sliding the anchor rod in the installation track, thereby further improving the convenience and applicability of the implementation of the embedded channel.

[0009] Optionally, the snap-fit ​​structure includes a sphere, an elastic member and a limit groove, wherein the limit groove is provided on the side wall of the embedded groove away from the groove opening, and a plurality of the limit grooves are provided, and the plurality of limit grooves are distributed along the length direction of the embedded groove, the elastic member is passed through the sliding end of the anchor rod, the sphere is fixed to one end of the elastic member close to the groove body, the sphere extends from the surface of the anchor rod under the elastic force of the elastic member, and the sphere is snap-fitted with the limit groove.

[0010] By adopting the above technical solution, the sphere is always in contact with the groove body under the elastic force of the elastic member. When the position of the anchor rod makes the sphere align with the limiting groove, the sphere extends into the limiting groove under the elastic force of the elastic member. The side wall of the limiting groove forms a limiting effect on the sphere along the circumference of the sphere, thereby limiting the position of the anchor rod, improving the stability of the anchor rod on the installation track before pouring concrete, improving the pouring accuracy, and thereby improving the strength and stability of the embedded groove.

[0011] Optionally, the anchor rod is an I-shaped structure, and the mounting rail includes two limit plates, which are arranged along the length direction of the channel body and are located on the side wall of the channel body away from the slot. The two limit plates are bent in a direction close to each other away from the channel body to form a sliding groove, and the cross-section of the sliding groove is C-shaped. The sliding end of the anchor rod is slidably arranged in the sliding groove.

[0012] By adopting the above technical solution, the anchor rod adopts an I-shaped structure and cooperates with two limit plates, so that the anchor rod cannot be separated from the channel body and can only slide in the sliding groove, thereby improving the stability of the anchor rod in the sliding groove. At the same time, the position of the anchor rod can be easily adjusted and fixed in conjunction with the snap-on structure.

[0013] Optionally, the slot of the slot body is configured to be dovetail shaped.

[0014] By adopting the above technical solution, the dovetail groove design can further improve the bolt fixing effect and further improve the stability of the overall structure.

[0015] Optionally, a first limiting tooth is provided on the inner side wall of the channel body at the notch, and a second limiting tooth is provided on the side of the screw head of the bolt close to the screw rod, and the first limiting tooth is meshed with the second limiting tooth.

[0016] By adopting the above technical solution, the mutual limiting effect formed by the engagement of the first limit tooth and the second limit tooth can effectively prevent the bolt from sliding in the slot of the slot body, thereby improving the stability of the bolt in the slot and further improving the stability of other components connected to the bolt.

[0017] Optionally, a washer and a locking nut are sleeved on the bolt, and the washer is located on a side of the locking nut close to the embedded groove.

[0018] By adopting the above technical solution, the bolt can be fixed or released by turning the locking nut, the bolt position adjustment is very convenient, and the gasket can effectively prevent the locking nut from loosening, further improving the stability of the connection.

[0019] Optionally, the slot of the slot body is filled with a filler.

[0020] By adopting the above technical solution, the filler fills the slot of the channel body, thereby preventing concrete slurry from flowing into the slot during the pouring process and affecting the subsequent use of the embedded channel.

[0021] Optionally, the channel body is arranged in an arc shape as a whole.

[0022] By adopting the above technical solution, the arc-shaped setting can make the channel body match the arc-shaped concrete structure, thereby improving the applicability of the implementation of the embedded channel.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The installation track and the clamping structure can realize the quick installation and fixation of multiple anchor rods. Compared with welding the anchor rods and the channel body, the implementation efficiency is effectively improved. In addition, the position of the anchor rod on the channel body can be adjusted. In the subsequent construction process, if the position of the anchor rod needs to be adjusted, the position of the anchor rod can be changed by sliding the anchor rod in the installation track, which further improves the convenience and applicability of the implementation of the embedded channel;

[0025] 2. The ball always abuts against the groove body under the elastic force of the elastic member. When the anchor rod is located so that the ball is aligned with the limiting groove, the ball extends into the limiting groove under the elastic force of the elastic member. The side wall of the limiting groove forms a limiting effect on the ball along the circumference of the ball, thereby limiting the position of the anchor rod, improving the stability of the anchor rod on the installation track before pouring concrete, improving the pouring accuracy, and thus improving the strength and stability of the embedded groove;

[0026] 3. The mutual limiting effect formed by the engagement of the first limiting tooth and the second limiting tooth can effectively prevent the bolt from sliding in the slot of the channel body, thereby improving the stability of the bolt in the slot and further improving the stability of other components connected to the bolt.

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a convenient assembled embedded groove, referring to Figure 1 and Figure 2 , including a channel body 1, a plurality of anchor rods 2 and a plurality of bolts 3. The channel body 1 is provided with a notch with a C-shaped cross section for the passage of cables, pipes, etc., and a plurality of bolts 3 are installed in the notch, and one end of the bolt 3 away from the screw head extends out of the notch for connecting other components. At the same time, a mounting track 4 is formed on the side wall of the channel body 1 away from the notch, and the anchor rod 2 has a sliding end and an anchoring end. The sliding end of each anchor rod 2 is slidably arranged in the mounting track 4, and the anchoring end of each anchor rod 2 is cast in concrete to fix the channel body 1, and a clamping structure is provided between the sliding end of each anchor rod 2 and the mounting track 4 to facilitate fixing the position of the anchor rod 2 in the mounting track 4.

[0036] During the specific construction, the sliding ends of the plurality of anchor rods 2 are first slid into the installation track 4, and the position of the anchor rods 2 is fixed by the clamping structure. After the installation is completed, the concrete can be poured, and then the bolts 3 can be installed as needed. By setting the anchor rods 2 on the installation track 4 and fixing the position of the anchor rods 2 with the clamping structure, the installation speed of the anchor rods 2 is improved, and the construction efficiency is greatly improved compared with welding. Moreover, the position of the anchor rods 2 can be adjusted by the clamping structure, thereby avoiding the steel bars in the concrete structure, further improving the convenience of the implementation of the embedded channel.

[0037] Specifically, refer to Figure 2 and Figure 3 The mounting track 4 includes two limit plates 41, which are arranged along the length direction of the channel body 1 and are located on the side wall of the channel body 1 away from the slot. The two limit plates 41 are close to the side edge of the channel body 1 and bent toward the center position to cooperate with the channel body 1 to form a sliding groove 42, and the cross-section of the sliding groove 42 is C-shaped, and the sliding end of the anchor rod 2 is arranged in the sliding groove 42.

[0038] Further, refer to Figure 1 and Figure 3 The anchor rod 2 is an I-shaped structure, and the two wide ends of the I-shaped structure of the anchor rod 2 are respectively a sliding end and an anchoring end. The sliding end of the anchor rod 2 is slidably arranged in the sliding groove 42, and the cross-sectional shape of the sliding end is adapted to the cross-sectional shape of the sliding groove 42. The two limit plates 41 limit the sliding end of the anchor rod 2 to prevent the anchor rod 2 from moving away from the channel body 1 to produce an anchoring effect.

[0039] Reference Figure 4 and Figure 5 The clamping structure includes a sphere 51, an elastic member 52 and a limiting groove 53. The limiting groove 53 is arranged on the side wall of the channel body 1 away from the groove, and a plurality of limiting grooves 53 are arranged. The plurality of limiting grooves 53 are distributed along the length direction of the channel body 1. The elastic member 52 is passed through the sliding end of the anchor rod 2 and faces the channel body 1. The sphere 51 is fixed to one end of the elastic member 52 close to the channel body 1, and the sphere 51 extends from the side of the anchor rod 2 close to the channel body 1 under the elastic force of the elastic member 52. The sphere 51 is clamped and matched with the limiting groove 53 to cooperate in limiting the anchor rod 2.

[0040] In this embodiment, the limit grooves 53 are provided corresponding to the number of anchor rods 2 actually provided, and another spare limit groove 53 may be provided near each preset limit groove 53, so as to fine-tune the position of the anchor rod 2 and avoid the steel bars and other structures in the concrete. In addition, if the anchor rod 2 is located at the preset position of the limit groove 53 and conflicts with the steel bars and other structures in the concrete, the anchor rod 2 may be slid to other positions to avoid the conflict, and at this time, the ball 51 is pressed against the channel body 1, which can also play a certain limiting role.

[0041] Preferably, the anchor rod 2 is provided with two groups of spheres 51 and elastic members 52 along the length direction of the channel body 1, and two limiting grooves 53 are correspondingly provided at each position of the channel body 1 for installing the anchor rod 2, so as to further improve the limiting effect. In addition, more numbers can be provided to further improve the limiting effect. In this embodiment, two groups are preferably used in consideration of the construction cost and other issues.

[0042] When in use, the sliding end of the anchor rod 2 is slid into the end of the sliding groove 42, and the ball 51 is squeezed into the sliding end of the anchor rod 2. After the anchor rod 2 is moved to a preset position, the ball 51 extends into the limit groove 53 under the elastic force of the elastic member 52 to fix the position of the anchor rod 2. It should be noted that when the anchor rod 2 moves, it will pass through other limit grooves 53, and the ball 51 will be stuck in the limit groove 53. At this time, the anchor rod 2 can be moved with force to force the ball 51 to shrink into the anchor rod 2 to achieve the sliding of the anchor rod 2.

[0043] Further, refer to Figure 1 and Figure 3 The inner side wall of the channel body 1 at the notch is provided with a first limiting tooth 6, and the side of the screw head of the bolt 3 close to the screw rod is provided with a second limiting tooth 7, and the first limiting tooth 6 and the second limiting tooth 7 are meshed. When installing the bolt 3, first extend the screw head of the bolt 3 into the notch and move along the length direction of the notch. After adjusting to the corresponding position, the screw head of the bolt 3 is pressed against the first limiting tooth 6, so that the first limiting tooth 6 and the second limiting tooth 7 are meshed, preventing the bolt 3 from moving and improving the stability of the connection of other components.

[0044] Further, refer to Figure 3 The screw rod of the bolt 3 is sleeved with a washer 8 and a locking nut 9, and the washer 8 is located on the side of the locking nut 9 close to the embedded channel. After adjusting the position of the bolt 3 at the notch, the locking nut 9 can be turned to make the screw head of the bolt 3 and the locking nut 9 clamp the channel body 1, fix the bolt 3 at the notch, and the washer 8 can effectively prevent the locking nut 9 from loosening, further improving the stability of the connection.

[0045] Preferably, refer to Figure 2 The notch of the channel body 1 can be set to a dovetail shape, and the screw head of the bolt 3 can be set to a corresponding shape so that the first limiting tooth 6 is meshed with the second limiting tooth 7. The dovetail notch can enhance the fixing effect of the bolt 3 and further improve the stability of the overall structure.

[0046] Preferably, refer to Figure 6 For concrete structures with arc-shaped structures, the channel body 1 can be set to an arc shape to meet the needs of special buildings and further improve the applicability of the embedded channel.

[0047] Further, refer to Figure 2The slot of the channel body 1 is filled with a filler 10, which fills the slot of the channel body 1 to prevent concrete slurry from flowing into the slot during the pouring process and affecting the subsequent use of the embedded channel. After the pouring is completed, the filler 10 is taken out and pipelines can be laid in the slot.

[0048] The implementation principle of a convenient assembled embedded channel disclosed in the embodiment of the present application is:

[0049] The channel body 1, bolts 3 and anchor rods 2 are all prefabricated parts and are transported to the construction site during construction;

[0050] First, according to the needs of the construction, a corresponding number of anchor rods 2 are sequentially slid into the installation track 4, and the spheres 51 on the anchor rods 2 are engaged with the corresponding limit grooves 53; then the slots are filled with fillers 10, and then concrete can be poured. After the concrete solidifies, the fillers 10 are taken out and the bolts 3 can be installed as needed;
