Description

Technical Field

[0001] The invention belongs to the technical field of building engineering connection structures, and in particular relates to an integrated steel bar locking full-grouting sleeve with a clamping groove. Background Art

[0002] With the booming prefabricated construction industry, the innovation of connector technology has become the key to improving construction quality and efficiency. Among them, the grouting sleeve connection technology, with its high efficiency and reliability, has played an increasingly important role in the connection of prefabricated components. The traditional full grouting sleeve design achieves a fast connection with the steel bars by grouting at both ends simultaneously. Although it effectively promotes assembly efficiency, it still faces many challenges in actual operation.

[0003] When the existing full grouting sleeve guides the two sides of the steel bar to connect, the steel bar axis often deviates due to improper operation or material differences, making it difficult to ensure accurate straight line alignment, which in turn affects the mechanical properties of the grouting connection and the stability of the overall structure. In addition, during the grouting process, the slight movement of the steel bar or the difference in the fluidity of the grouting material can easily cause position deviation, posing a potential threat to the construction quality. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an integrated steel bar locking full-grouting sleeve with a slot.

[0005] In order to achieve the purpose, the technical solution adopted by the present invention is as follows:

[0006] An integrated steel bar locking full grouting sleeve with a slot is used to connect adjacent steel bar members, and is characterized in that it includes a grouting sleeve body, an upper sealing plug, a lower sealing plug, an upper slot locator and a lower slot locator.

[0007] The upper end of the grouting sleeve body is provided with an upper opening and a grouting outlet, and the lower end is provided with a lower opening and a grouting outlet; the grouting outlet and the grouting outlet are connected to the interior of the grouting sleeve body; the upper opening and the lower opening are axially arranged; the grouting outlet and the grouting outlet are horizontally arranged relative to the grouting sleeve body; the diameter of the grouting outlet is smaller than the diameter of the grouting outlet.

[0008] The upper sealing plug and the lower sealing plug are respectively arranged in the upper opening and the lower opening. Holes are left inside the upper sealing plug and the lower sealing plug, and the diameter of the holes is the same as the diameter of the steel bar body. The steel bar body passes through the holes, and the angle between the upper sealing plug, the lower sealing plug and the steel bar body is 90°.

[0009] The diameter cross section of one end of the steel bar body is welded with the diameter cross section of the upper hemispherical small iron ball to form an upper connector; the diameter cross section of one end of the steel bar body is welded with the diameter cross section of the lower hemispherical small iron ball to form a lower connector. The center of the cross section of the upper hemispherical small iron ball coincides with the center of the cross section of the steel bar body diameter; the center of the cross section of the lower hemispherical small iron ball coincides with the center of the cross section of the steel bar body diameter.

[0010] The upper card slot locator and the lower card slot locator are respectively inserted and connected with the adjacent upper connector and the lower connector.

[0011] The grouting sleeve body is provided with an upper slot locator and a lower slot locator for connecting the upper connector and the lower connector. The opening width of the upper slot locator is larger than the diameter of the upper hemispherical small iron ball and the diameter of the steel bar body; the opening width of the lower slot locator is larger than the diameter of the lower hemispherical small iron ball and the diameter of the steel bar body.

[0012] The upper and lower slot locators are vertically arranged relative to the inner wall of the grouting sleeve body, and four edges of the upper and lower slot locators bases parallel to the inner wall of the grouting sleeve body are welded to the inner wall of the grouting sleeve body.

[0013] The angle between the central axis of the upper slot locator and the lower slot locator and the grouting sleeve body is 45°.

[0014] The upper slot locator is composed of a base with a hole in the middle and two symmetrical arc-shaped elastic steel sheets. The upper slot locator is connected to the upper connector by insertion, and the angle between the upper slot locator and the upper connector is 90°.

[0015] The lower card slot locator is composed of a base with a hole in the middle and two symmetrical arc-shaped elastic steel sheets. The lower card slot locator is connected to the lower connector by insertion, and the angle between the lower card slot locator and the lower connector is 90°.

[0016] The grout outlet and the grouting port are horizontally arranged relative to the grouting sleeve body, and the angle between the grout outlet and the grouting port and the central axis of the grouting sleeve body is 90°. The grout outlet and the grouting port are located on the side wall of the grouting sleeve body and are arranged on the same side. The diameter of the grout outlet is smaller than that of the grouting port.

[0017] Compared with existing products, the present invention has the following beneficial effects:

[0018] Compared with the existing full grouting sleeve structure and practice, the breakthrough design of this invention cleverly combines the automatic centering positioning and stable locking mechanism of the sleeve steel bar, fundamentally solving the problem of easy displacement of the steel bar in the sleeve, thereby significantly reducing the probability of potential defects during the grouting process. This innovation not only ensures the uniform distribution and tight filling of the grouting material, but also strengthens the overall performance of the grouting sleeve connection at the structural level.

[0019] Compared with the traditional full grouting sleeve process, this innovative design only adds one welding step and slightly increases the working hours, but significantly reduces the risk of grouting defects, completely eliminates the problem of steel bar offset, greatly reduces rework, and effectively improves construction efficiency and cost control. This invention not only optimizes the operation process, but also shows outstanding advantages in resource conservation and environmental protection, achieving a dual improvement in economic and ecological benefits.

The use of these terms in this article and the specification of the present invention is purely for the purpose of elaborating on specific implementation cases, and is not intended to constitute any form of limitation on the scope or connotation of the present invention.

[0034] Reference Figures 1 to 9 The present invention provides an integrated steel bar locking full grouting sleeve with a slot, which is used to connect adjacent steel bars, and is characterized in that it includes a grouting sleeve body 1, an upper sealing plug 10, a lower sealing plug 12, an upper slot locator 5 and a lower slot locator 7;

[0035] The upper end of the grouting sleeve body 1 is provided with an upper opening 9 and a grouting port 3, and the lower end is provided with a lower opening 11 and a grouting port 2; the grouting port 3 and the grouting port 2 are connected to the interior of the grouting sleeve body 1; the upper opening 9 and the lower opening 11 are axially arranged; the grouting port 3 and the grouting port 2 are horizontally arranged relative to the grouting sleeve body 1;

[0036] The upper sealing plug 10 and the lower sealing plug 12 are respectively disposed in the upper opening 9 and the lower opening 11;

[0037] The upper clamping groove positioner 5 and the lower clamping groove positioner 7 are respectively connected to one end of the adjacent steel bar connector.

[0038] In this embodiment, adjacent reinforcement members are respectively set as upper reinforcement member a and lower reinforcement member b, wherein the upper slot locator 5 is connected to one end of the upper connector 13 , and the lower slot locator 7 is connected to one end of the lower connector 14 .

[0039] The grouting port 2 and the grouting outlet 3 of this embodiment are arranged horizontally relative to the grouting sleeve body 1. At the same time, because the upper slot locator 5 and the lower slot locator 7 are arranged, adjacent steel bars can be positioned and supported to ensure that adjacent steel bars remain in a straight line without deviation during the grouting process.

[0040] Specifically, an upper slot locator 5 for inserting the upper connector 13 is provided in the grouting sleeve body 1 , and four edges of the base of the upper slot locator 5 parallel to the grouting sleeve body 1 are welded to the inner wall surface of the grouting sleeve body 1 .

[0041] The angle between the upper slot locator 5 and the central axis of the grouting sleeve body 1 is 90°;

[0042] Specifically, a lower slot locator 7 for inserting the lower connector 14 is provided in the grouting sleeve body 1 , and four edges of the base of the lower slot locator 7 parallel to the grouting sleeve body 1 are welded to the inner wall surface of the grouting sleeve body 1 .

[0043] The included angle between the lower slot locator 7 and the central axis of the grouting sleeve body 1 is 90°;

[0044] The structural design of the upper slot locator 5 and the holes in the base can increase the bonding force between the grouting sleeve body 1 and the grouting material 4, and ensure that the upper connector 13 is stuck in the middle of the upper slot locator 5. The two arc-shaped elastic steel sheets of the upper slot locator 5 are more conducive to the flow of the grouting material 4 inside the grouting sleeve.

[0045] The structural design of the lower slot locator 7 and the hole in the base can increase the bonding force between the grouting sleeve body 1 and the grouting material 4, and ensure that the lower connector 14 is stuck in the middle of the lower slot locator 7. The two arc-shaped elastic steel sheets of the lower slot locator 7 are more conducive to the flow of the grouting material 4 inside the grouting sleeve.

[0046] In this embodiment, the distance between the position of the upper slot locator 5 and the upper opening 9 is greater than the diameter of the steel bar, generally greater than eight times or more; the distance between the position of the lower slot locator 7 and the lower opening 11 is greater than the diameter of the steel bar, generally greater than eight times or more; this can ensure the anchoring length of the steel bar and the grouting sleeve body 1, so as to improve the bearing capacity of the connection between the steel bar and the grouting sleeve body 1.

[0047] Specifically, the grouting port 3 is horizontally arranged relative to the grouting sleeve body 1, the angle between the grouting port 3 and the central axis of the grouting sleeve body 1 is 90°, the lower end of the grouting port 3 is located on the side wall of the grouting sleeve body 1 and is arranged on the same side as the grouting port 2, and the caliber of the grouting port 3 is smaller than the caliber of the grouting port 2. The above arrangement can improve the grouting efficiency and further improve the grouting fullness.

[0048] Specifically, the upper connector 13 includes an upper steel bar body a and an upper hemispherical small iron ball 6, and the diameter cross section of the upper steel bar body a and the diameter cross section of the upper hemispherical small iron ball 6 are welded together with the center of the circle coinciding with each other;

[0049] Specifically, the lower connector 14 includes a lower steel bar body b and a lower hemispherical small iron ball 8, and the diameter cross section of the lower steel bar body b and the diameter cross section of the lower hemispherical small iron ball 8 are welded together with the center of the circle coinciding with each other;

[0050] The above structural arrangement can ensure that the upper slot locator 5 and the lower slot locator 7 are better connected to the steel bar as a whole, and the formation of the upper connector 13 and the lower connector 14 is more convenient for the combination of the upper slot locator 5 and the lower slot locator 7.

[0051] In this embodiment, one end of the upper connector 13 is connected to the upper slot locator 5, and the other end is connected through the upper sealing plug 10. One end of the lower connector 14 is connected to the lower slot locator 7, and the other end is connected through the lower sealing plug 12.

[0052] Specifically, a hole is left in the middle of the upper sealing plug 10, and the diameter of the hole is the same as the diameter of the upper steel bar body a; a hole is left in the middle of the lower sealing plug 12, and the diameter of the hole is the same as the diameter of the lower steel bar body b.

[0053] With such a configuration, the upper steel bar body a can better pass through the upper sealing plug 10 and fit in exactly, because the hole size limit cannot continue to move downward and will not move upward due to the grouting process, thereby achieving the purpose of fixing the upper steel bar body a together. The lower steel bar body b can better pass through the lower sealing plug 12 and fit in exactly, because the hole size limit cannot continue to move downward and will not move upward due to the grouting process, thereby achieving the purpose of fixing the lower steel bar body b together.

[0054] When assembling the integrated steel bar locking full grouting sleeve with a slot of the present scheme, firstly, four edges of the base of the upper slot locator 5 parallel to the grouting sleeve body 1 are welded to the inner wall surface of the grouting sleeve body 1, and then the diameter section of the upper steel bar body a and the diameter section of the upper hemispherical small iron ball 6 are welded together to form an upper connector 13, and then the other end of the upper steel bar body a is passed through the upper sealing plug 10, and finally the upper connector 13 is inserted into the upper slot locator 5 until the upper connector 13 is stuck in the upper slot locator 5 and cannot continue to move downward due to the elastic limit and is just stuck inside; then the four edges of the base of the lower slot locator 7 parallel to the grouting sleeve body are welded together to form an upper connector 13, and then the other end of the upper steel bar body a is passed through the upper sealing plug 10, and finally the upper connector 13 is inserted into the upper slot locator 5 until the upper connector 13 is stuck in the upper slot locator 5 and cannot continue to move downward due to the elastic limit; then 1 is welded to the inner wall surface of the grouting sleeve body 1, and then the diameter section of the lower steel bar body b and the diameter section of the lower hemispherical small iron ball 8 are welded together to form a lower connector 14, and then the other end of the lower steel bar body b is passed through the lower sealing plug 12, and finally the lower connector 14 is inserted into the lower card slot locator 7 until the lower connector 14 is stuck in the lower card slot locator 7 and cannot continue to move downward due to the elastic limit and is just stuck inside; then the upper sealing plug 10 and the lower sealing plug 12 are just inserted into the upper opening 9 and the lower opening 11 to complete the assembly; of course, the actual construction can appropriately adjust the installation steps according to the on-site conditions, and only the above cooperation needs to be achieved.

[0055] When grouting, the integrated steel bar locking full grouting sleeve with a slot of the present invention pours the grouting material 4 into the grouting sleeve body 1 from the grouting port 2, and the holes left inside the base of the lower slot locator 7 are more conducive to the upward flow of the grouting material 4, and the two arc-shaped elastic steel sheet structural design of the lower slot locator 7 is more conducive to the passage of the grouting material 4; the holes left inside the base of the upper slot locator 5 are more conducive to the upward flow of the grouting material 4, and the two arc-shaped elastic steel sheet structural design of the upper slot locator 5 is more conducive to the passage of the grouting material 4;

[0056] The beneficial effects of the integrated steel bar locking full grouting sleeve with a slot of this solution are as follows:

[0057] 1. The grouting fullness is improved, and the diameter of the grouting outlet 3 is smaller than the diameter of the grouting outlet 12, so as to solve the problem of grouting defects in the internal cavity of the grouting sleeve body 1 above the grouting outlet 3.

[0058] 2. The holes in the base of the upper slot locator 5 and the lower slot locator 7 further improve the density and grouting efficiency of the grouting material 4. The upper connector 13 and the lower connector 14 are arranged in conjunction with the slot locator to position and support the steel bars, ensuring that the steel bars remain in a straight line without deviation during the grouting process.

[0059] 3. The positions of the upper slot locator 5 and the lower slot locator 7 can determine the anchoring length of the steel bar and the grouting sleeve body 1, greatly improving the bearing capacity of the connection between the steel bar and the grouting sleeve body 1.

[0060] 4. The arc-shaped elastic steel sheet structure of the upper slot locator 5 and the lower slot locator 7 is more conducive to the passage of the grouting material 4.

[0061] 5. The structural design with holes inside the upper sealing plug 10 and the lower sealing plug 12 is more conducive to the passage of the steel bar body and can ensure that the steel bar is kept in a straight line without deviation during the grouting process.
