Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a grouting sleeve for connecting steel bars. Background Art

[0002] In the field of construction, grouting sleeves for steel bar connections play a vital role. At present, when performing steel bar connection grouting operations, the commonly used grouting sleeves have major problems in the way they are sealed after grouting is completed.

[0003] In the existing technical solutions, the staff usually holds the sealing plug and then uses a hammer to knock the sealing plug into the connecting pipe for sealing. This method has many disadvantages: first, the operation process is cumbersome, and the staff needs to spend more time and energy on the sealing operation, resulting in low construction efficiency. Secondly, there are certain safety hazards in using a hammer for sealing, which may cause harm to the staff. Moreover, the sealing of this sealing method is difficult to ensure, and leakage problems are prone to occur, affecting the construction quality and progress. For this reason, we proposed a grouting sleeve for steel bar connection. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a grouting sleeve for connecting steel bars, and solve the above-mentioned problem.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A grouting sleeve for connecting steel bars comprises a sleeve body and two connecting tubes fixedly connected to the sleeve body, the interiors of the two connecting tubes are fixedly connected to a limiting plate, two first flow holes are symmetrically provided on the limiting plate, a slidable sealing plate is provided inside the connecting tube at the rear side of the limiting plate, two sealing blocks are fixedly installed on a side wall of the sealing plate close to the limiting plate at positions corresponding to the two first flow holes, the two sealing blocks can respectively block the two first flow holes, two second flow holes are provided on the sealing plate, the two second flow holes are staggered with the two sealing blocks, a connecting groove is provided on a side wall of the sealing plate close to the limiting plate, a traction rope for driving the sealing plate to slide is fixedly connected inside the connecting groove, and the traction rope slides through the limiting plate.

[0007] A connecting block is fixedly mounted on a side wall of the limiting plate close to the sealing plate at a position corresponding to the connecting groove, and the shape and size of the connecting block are adapted to the internal shape and size of the connecting groove.

[0008] The connecting block is provided with a connecting hole, which passes through the interior of the limiting plate. One end of the traction rope away from the connecting groove passes through the connecting hole and extends to the outside of the connecting pipe.

[0009] The two first circulation holes are both arc-shaped through holes, the two sealing blocks are both arc-shaped blocks, and the shape and size of the sealing blocks are matched with the shape and size of the inside of the first circulation holes.

[0010] A sealing gasket is fixedly connected to the outer wall surface of the sealing block. The sealing gasket is an arc-shaped elastic block, and the cross section of the sealing gasket is a triangle.

[0011] A sliding groove is provided on the inner wall surface of the connecting pipe, and a sliding block is fixedly connected to the outer wall surface of the sealing plate at a position corresponding to the sliding groove, and the sliding block is slidably arranged inside the sliding groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting a traction rope to pull the matching structure of the sealing plate, the limit plate and the sealing block, the effect of efficiently and conveniently blocking the opening of the connecting pipe is achieved. When in use, the inside of the sleeve body is grouted through the lower connecting pipe. After the grouting is completed, the connecting hole is pulled outward to drive the sealing plate to slide forward inside the connecting pipe until the sealing plate contacts the limit plate. At this time, the sealing block on the sealing plate will block the first flow hole on the limit plate, and the second flow hole will also be blocked by the limit plate, thereby quickly and effectively blocking the opening of the connecting pipe. Compared with the existing method of sealing with a hammer by the staff holding the sealing plug, this structural design is faster and more effective, greatly improving the construction efficiency.

[0014] 2. By setting a sealing gasket, the sealing effect is improved. The sealing gasket is fixedly connected to the outer wall of the sealing block. The sealing gasket is an arc-shaped elastic block with a triangular cross section. When the sealing block and the first flow hole are closed, the sealing gasket can further fill the gap, improve the sealing, avoid leakage, and ensure construction efficiency.

[0015] 3. By setting the connection groove and the connection block, the effect of positioning and guiding to improve work efficiency is achieved. The connection groove installed on the limit plate cooperates with the connection block to play a role in positioning and guiding the sealing plate, so that it can quickly and accurately close with the limit plate during the sliding process, reducing the adjustment time and improving work efficiency.

[0023] Figure 1~Figure 5 It is the best embodiment of the utility model, and the following Figure 1 ~Attached Figure 5 The utility model is further described.

[0024] A grouting sleeve for steel bar connection includes a sleeve body 1 and two connecting pipes 2 fixedly connected to the sleeve body 1. The two connecting pipes 2 are arranged up and down and are respectively perpendicular to the sleeve body 1. The interior of the sleeve body 1 can be grouted through the connecting pipes 2. The lower connecting pipe 2 is used for feeding, and the upper connecting pipe 2 is used for discharging. During the grouting process, covers can be set at the upper and lower ends of the sleeve body 1 for sealing.

[0025] The interiors of the two connecting tubes 2 are fixedly connected to the limiting plate 4, the shape and size of the limiting plate 4 are adapted to the shape and size of the interior of the connecting tube 2, two first flow holes 5 are symmetrically provided on the limiting plate 4, the interior of the connecting tube 2 is provided with a slidable sealing plate 8 located on the rear side of the limiting plate 4, the shape and size of the sealing plate 8 are adapted to the shape and size of the interior of the connecting tube 2, two sealing blocks 10 are fixedly installed on the side wall of the sealing plate 8 close to the limiting plate 4 at the positions corresponding to the two first flow holes 5, the two sealing blocks 10 can respectively block the two first flow holes 5, two second flow holes 9 are provided on the sealing plate 8, a connecting groove 12 is provided on the side wall of the sealing plate 8 close to the limiting plate 4, the interior of the connecting groove 12 is fixedly connected with a traction rope 3 for driving the sealing plate 8 to slide, the traction rope 3 slides through the limiting plate 4, the traction rope 3 is the prior art and will not be elaborated here.

[0026] When grouting is performed inside the sleeve body 1 through the connecting pipe 2 , the grout can flow into the sleeve body 1 through the first flow hole 5 on the limiting plate 4 and the second flow hole 9 on the sealing plate 8 after entering the connecting pipe 2 .

[0027] A connecting block 6 is fixedly installed on the side wall of the limiting plate 4 close to the sealing plate 8 at a position corresponding to the connecting groove 12. The shape and size of the connecting block 6 are adapted to the internal shape and size of the connecting groove 12. A connecting hole 7 is opened on the connecting block 6. The connecting hole 7 passes through the interior of the limiting plate 4. The end of the traction rope 3 away from the connecting groove 12 passes through the interior of the connecting hole 7 and extends to the outside of the connecting pipe 2.

[0028] The two first flow holes 5 are both arc-shaped through holes, the two sealing blocks 10 are both arc-shaped blocks, and the shape and size of the sealing blocks 10 are adapted to the shape and size of the inside of the first flow holes 5. The two second flow holes 9 and the two sealing blocks 10 are staggered. When the limiting plate 4 and the sealing plate 8 are combined together, the sealing block 10 on the sealing plate 8 will block the first flow hole 5 on the limiting plate 4, and at the same time, the second flow hole 9 will also be blocked by the limiting plate 4, thereby achieving the effect of sealing the opening of the connecting pipe 2.

[0029] When in use, grouting is performed inside the sleeve body 1 through the lower connecting pipe 2. After grouting is completed inside the sleeve body 1, the sealing plate 8 can be driven to slide forward inside the connecting pipe 2 by pulling the traction rope 3 outward until the sealing plate 8 contacts the limit plate 4. At this time, the sealing block 10 on the sealing plate 8 will block the first flow hole 5 on the limit plate 4, and the second flow hole 9 will also be blocked by the limit plate 4, thereby achieving the effect of sealing the opening of the connecting pipe 2.

[0030] When in use, the cooperation between the connecting groove 12 and the connecting block 6 can play a role in positioning and guiding the sealing plate 8, so that it can quickly complete the closure with the limiting plate 4, thereby improving work efficiency.

[0031] The outer wall of the sealing block 10 is fixedly connected with a sealing gasket 11, which is an arc-shaped elastic block and has a triangular cross-section. The sealing gasket 11 can be set on the outer walls of the four sides of the sealing block 10 and can be installed according to actual usage.

[0032] By installing the sealing gasket 11 with a triangular cross section on the sealing block 10, the sealing performance can be further improved when the sealing block 10 and the first flow hole 5 are closed, thereby avoiding the problem of liquid leakage and ensuring the construction efficiency.

The slide groove 14 can be provided with multiple groups to improve the sliding stability of the sealing plate 8, and can be provided according to actual usage. Since the slurry is a fluid, the slider 13 can squeeze out the slurry inside the slide groove 14 when the sealing plate 8 slides, and the slurry does not hinder the movement of the slider 13.

[0034] The working principle and workflow of the utility model are as follows:

[0035] When in use, the inside of the sleeve body 1 is grouted by feeding material through the lower connecting pipe 2. After the grouting of the inside of the sleeve body 1 is completed, the sealing plate 8 can be driven to slide forward inside the connecting pipe 2 by pulling the traction rope 3 outward until the sealing plate 8 contacts the limit plate 4. At this time, the sealing block 10 on the sealing plate 8 will block the first flow hole 5 on the limit plate 4, and the second flow hole 9 will also be blocked by the limit plate 4, thereby achieving the effect of sealing the opening of the connecting pipe 2. Compared with the existing method of sealing the connecting pipe 2 with a hammer by a staff holding a sealing plug, this equipment can complete the sealing of the connecting pipe 2 more quickly and effectively, and at the same time can avoid the safety hazards caused by sealing with a hammer.
