Description

Technical Field

[0001] This utility model relates to the field of grouting technology, specifically to a ductile iron grouting sleeve. Background Technology

[0002] As connecting components, grouting sleeves have become increasingly diverse in models and varieties with the promotion and application of prefabricated buildings, resulting in varying performance levels among different types.

[0003] To ensure that the inner wall of the ductile iron grouting sleeve can stably maintain the stress of the cement inside the sleeve, protrusions are usually installed inside the sleeve. However, these protrusions can affect the smoothness of grouting, the grouting speed, and the fullness of the grouting.

[0004] Chinese patent CN221168399U discloses a grouting sleeve, comprising a sleeve, pre-installed reinforcing bars, and post-inserted reinforcing bars. An anchor plate is welded to one end of each of the pre-installed and post-inserted reinforcing bars, and this end extends into the sleeve. Several internal threads are engraved on the inner wall of the sleeve. While welding the anchor plate to one end of the reinforcing bar increases the interaction between the reinforcing bar and the grout, it also results in high material costs, reduced strength, and reduced grouting speed. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a ductile iron grouting sleeve. This ductile iron grouting sleeve can quickly fill the sleeve, making the grouting uniform and full, and has the advantage of stable stress dispersion.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ductile iron grouting sleeve is provided, comprising:

[0008] The cylinder has a grouting port and a grout outlet. The inner wall of the cylinder is a straight cylinder wall. The outer circumference of the outer wall of the cylinder is provided with anchoring rings and reinforcing ribs. The anchoring rings are distributed along the circumference of the outer wall. The reinforcing ribs pass through the anchoring rings and are distributed along the length of the cylinder.

[0009] The grouting inlet is used for grouting, and the grout outlet is used for grout discharge. The circumferential anchors reinforce the strength of the cylinder. The reinforcing ribs not only strengthen the cylinder itself but also the circumferential anchors, significantly increasing the overall strength of the outer cylinder wall. Therefore, even with an inner straight cylinder wall, grouting can be performed effectively, achieving rapid and full grouting, thus strengthening the sleeve's body. This solves the problems of slow and incomplete grouting during construction. Furthermore, through innovative structural modifications, it strengthens the cylinder structure and improves the performance of the grouting sleeve.

[0010] In some embodiments, a plurality of anchoring rings are provided, and the plurality of anchoring rings are distributed along the length direction of the outer cylinder wall.

[0011] Setting multiple fixed anchors can enhance the reinforcing effect, thus strengthening the entire outer cylinder wall.

[0012] In some embodiments, six anchoring rings are provided, with three anchoring rings near the grouting port and three anchoring rings near the grout outlet.

[0013] Since both the grouting port and the grout outlet require grout to enter and exit, they are subjected to greater stress. Therefore, anchoring rings are installed at the grouting port and the grout outlet to achieve a better reinforcement effect.

[0014] In some embodiments, the anchoring ring near the grouting port is the first anchoring ring, and the anchoring ring near the grout outlet is the second anchoring ring. The distance between adjacent first anchoring rings is equal, and the distance between adjacent second anchoring rings is equal.

[0015] The anchoring ring located at the grouting port is the first anchoring ring, and the anchoring ring located at the grouting outlet is the second anchoring ring. This arrangement ensures that the first anchoring rings at the grouting port and the second anchoring rings at the grouting outlet are evenly spaced, thereby improving the uniformity of stress distribution.

[0016] In some embodiments, the reinforcing ribs run in a straight line through each anchoring ring.

[0017] Straight-lined stiffeners can better distribute stress.

[0018] In some embodiments, the reinforcing rib extends in the same direction as the axis of the cylinder.

[0019] Straight-lined reinforcing ribs offer better connectivity.

[0020] In some embodiments, the thickness of the anchoring ring is 2 to 5 mm, and the width of the bottom surface of the anchoring ring is 3 to 5 mm.

[0021] Anchor rings of this size can save on materials while ensuring strength.

[0022] In some embodiments, the anchoring ring has a thickness of 2 mm and a bottom width of 5 mm.

[0023] In some embodiments, the anchoring ring has a thickness of 2 mm and a bottom width of 3 mm.

[0024] This size of reinforcing rib saves on material while ensuring strength.

[0025] In some embodiments, the thickness of the reinforcing rib is 2-5 mm, and the width of the bottom surface of the reinforcing rib is 3-5 mm.

[0026] This size of reinforcing rib saves on material while ensuring strength.

[0027] In some embodiments, the thickness of the reinforcing rib is 2 mm, and the bottom width of the reinforcing rib is 5 mm.

[0028] The beneficial effects of this utility model of a ductile iron grouting sleeve are as follows:

[0029] This utility model relates to a ductile iron grouting sleeve, which features a straight inner wall surface. This smooth, straight wall surface allows for efficient and complete grouting, ensuring the sleeve is filled completely. Furthermore, anchoring rings and reinforcing ribs are incorporated into the outer wall surface, effectively strengthening the sleeve and preventing stress concentration issues that could compromise its strength due to the straight inner wall surface.

[0039] Example 1

[0040] As connecting components, grouting sleeves have become increasingly diverse in model and variety with the promotion and application of prefabricated buildings, with varying performance levels among different types.

[0041] To ensure that the inner wall of the ductile iron grouting sleeve can stably maintain the stress of the cement inside the sleeve, protrusions are usually installed inside the sleeve. However, these protrusions can affect the smoothness of grouting, the grouting speed, and the fullness of the grouting.

[0042] Chinese patent CN221168399U discloses a grouting sleeve, comprising a sleeve, pre-installed reinforcing bars, and post-inserted reinforcing bars. An anchor plate is welded to one end of each of the pre-installed and post-inserted reinforcing bars, and this end extends into the sleeve. Several internal threads are engraved on the inner wall of the sleeve. While welding the anchor plate to one end of the reinforcing bar increases the interaction between the reinforcing bar and the grout, it also results in high material costs, reduced strength, and reduced grouting speed.

[0043] Therefore, in the field of grouting sleeve technology, there is currently no ductile iron grouting sleeve that can achieve rapid and full grouting while also strengthening the sleeve body in structural design. This embodiment aims to overcome the problems in existing grouting sleeves where prefabrication of components and on-site grouting are not smooth, and the grout cannot quickly and fully fill the sleeve body. It provides a reinforced ductile iron grouting sleeve that facilitates grouting, enabling rapid filling of the sleeve body with grout, uniform and compact filling of the inner sleeve wall, and improving connection strength and performance.

[0044] This embodiment discloses a ductile iron grouting sleeve. Please refer to [link / reference]. Figures 1-2 ,include:

[0045] The cylinder 1 has a grouting port 2 and a grout outlet 3. The inner wall 4 of the cylinder 1 is a straight wall. The outer wall 9 of the cylinder 1 is provided with an anchoring ring 5 and a reinforcing rib 6. The anchoring ring 5 is distributed along the circumference of the outer wall 9. The reinforcing rib 6 passes through the anchoring ring 5 and is distributed along the length of the cylinder 1.

[0046] Grouting port 2 is used for grouting, and grout outlet 3 is used for grout discharge. The circumferential anchor strengthens the strength of cylinder 1. The reinforcing rib 6 not only strengthens the cylinder 1 but also the circumferential anchor, significantly increasing the strength of the outer wall of the entire cylinder 1. Therefore, even with an inner straight cylinder wall, grouting can be carried out effectively, achieving rapid and full grouting, thus strengthening the sleeve body. This solves the problems of slow and incomplete grouting during construction. Simultaneously, through innovative structural modifications, it strengthens the cylinder structure and improves the performance of the grouting sleeve.

[0047] Specifically,

[0048] Functions of grouting port 2 and grout outlet 3: Grouting port 2 is used for grouting, and grout outlet 3 is used for grout discharge. The grouting sleeve is equipped with a grouting hole and a grout outlet 3. The grouting hole is the inlet for adding grout, and the grout outlet 3 is the outlet for venting air during grouting and for discharging excess grout after filling.

[0049] Anchor rings 5 ​​are distributed along the circumference of the cylinder 1, and reinforcing ribs 6 penetrate the anchor rings 5 ​​and are distributed along the length of the cylinder 1. This structural design not only strengthens the cylinder 1 but also the anchor rings 5, thereby greatly improving the strength of the outer wall of the entire cylinder 1.

[0050] By using an inner straight cylinder wall, grouting can be carried out effectively, achieving rapid and full grouting, which strengthens the sleeve body. This design solves the problems of slow and incomplete grouting during construction. At the same time, through innovative structural modification, it strengthens the cylinder body structure and improves the performance of the grouting sleeve.

[0051] In this embodiment, there are several anchor rings 5, and the several anchor rings 5 ​​are distributed along the length direction of the outer cylinder wall 9.

[0052] Setting multiple fixed anchors can enhance the reinforcing effect, thus strengthening the entire outer cylinder wall 9.

[0053] Specifically, by setting multiple anchoring rings 5 ​​along the length of the cylinder 1, it can be ensured that the outer wall of the entire cylinder 1 is uniformly reinforced. This uniformly distributed reinforcement helps to improve the overall stability and load-bearing capacity of the cylinder 1.

[0054] The anchoring ring 5 helps to improve the bending resistance of the cylinder 1. When subjected to external loads, especially bending loads, the anchoring ring 5 can effectively disperse stress and reduce local stress concentration, thereby improving the bending resistance of the cylinder 1.

[0055] The presence of the anchoring ring 5 enhances the shear resistance of the cylinder 1. When subjected to shear force, the anchoring ring 5 can provide additional shear resistance, reducing the deformation or damage to the cylinder 1 caused by excessive shear force.

[0056] During the grouting process, multiple anchor rings 5 ​​can provide more grouting points, making the grouting more uniform and faster, thereby improving construction efficiency. Due to the reinforcing effect of the anchor rings 5, the durability and service life of the cylinder 1 can be extended. Under long-term load and environmental influences, multiple anchor rings 5 ​​can reduce fatigue damage to the cylinder 1 and extend its service life.

[0057] In this embodiment, six anchoring rings 5 ​​are provided, three of which are close to the grouting port 2 and three of which are close to the grout outlet 3.

[0058] Since both the grouting port 2 and the grouting outlet 3 require grout to enter and exit, they are subjected to greater stress. Therefore, anchoring rings 5 ​​are installed at the grouting port 2 and the grouting outlet 3 to achieve better reinforcement.

[0059] Specifically,

[0060] The anchoring rings 5 ​​can specifically reinforce these areas to cope with the large stresses that may be generated during grouting. Setting anchoring rings 5 ​​near the grouting port 2 and the grout outlet 3 helps to disperse stress in these areas. The grouting material may exert pressure on the sleeve wall during entry and exit; the anchoring rings 5 ​​can effectively disperse this pressure and reduce local stress concentration. Because the stress near the grouting port 2 and the grout outlet 3 is relatively high, these areas are more prone to cracking. Setting anchoring rings 5 ​​can improve the crack resistance of these areas, reduce crack formation, and thus improve the overall durability of the sleeve. The anchoring rings 5 ​​not only strengthen local areas but also enhance the overall integrity of the structure. The anchoring rings 5 ​​can connect different parts of the cylinder 1 together, forming a more robust integrated structure. Setting anchoring rings 5 ​​near the grouting port 2 and the grout outlet 3 ensures that the grouting material fills the sleeve better, improving the fullness and uniformity of the grouting, thereby improving the grouting quality.

[0061] In this embodiment, the anchoring ring 5 near the grouting port 2 is the first anchoring ring 5, and the anchoring ring 5 near the grout outlet 3 is the second anchoring ring 5. The spacing between adjacent first anchoring rings 5 ​​is equal, and the spacing between adjacent second anchoring rings 5 ​​is equal.

[0062] The anchoring ring 5 located at the grouting port 2 is the first anchoring ring 5, and the anchoring ring 5 located at the grout outlet 3 is the second anchoring ring 5. This arrangement ensures that the first anchoring rings 5 ​​at the grouting port 2 are evenly spaced, and the second anchoring rings 5 ​​at the grout outlet 3 are evenly spaced, thereby improving the uniformity of stress distribution.

[0063] Specifically,

[0064] By ensuring that the spacing between the first anchor ring 5 (near the grouting port 2) and the second anchor ring 5 (near the grout outlet 3) is equal, a more uniform stress distribution can be achieved along the entire length of the cylinder 1. This uniform distribution helps reduce local stress concentration, thereby reducing the risk of structural damage. The equally spaced anchor rings 5 ​​also help maintain the symmetry of the structure, which is crucial for ensuring the stability and balance of the structure under load. Symmetrical structures can generally distribute loads more evenly, reducing structural deformation caused by uneven load distribution. The equally spaced anchor rings 5 ​​can improve the efficiency of structural material use. By precisely controlling the position of the anchor rings 5, it can be ensured that each anchor ring 5 plays a role in the areas most in need of reinforcement, thereby avoiding material waste. The equally spaced anchor rings 5 ​​design also facilitates construction. Construction workers can easily locate the position of each anchor ring 5 according to the preset spacing, which helps to improve construction speed and accuracy. The equally spaced anchor rings 5 ​​design also facilitates later maintenance and inspection. Since the position of the anchor rings 5 ​​is regular and predictable, maintenance personnel can more easily locate each anchor ring 5 for regular inspection and necessary maintenance.

[0065] In this embodiment, the reinforcing rib 6 runs through each anchoring ring 5 in a straight line.

[0066] The straight-lined reinforcing rib 6 can better disperse stress.

[0067] Specifically,

[0068] The straight-lined stiffeners 6 effectively disperse the stress generated in the cylinder 1 under load. This dispersion helps reduce local stress concentration, thereby lowering the risk of fatigue failure. The straight layout of the stiffeners 6 improves the bending resistance of the cylinder 1. Under bending moment, the straight stiffeners 6 provide additional bending capacity, reducing bending deformation of the cylinder 1. The straight-lined stiffeners 6 also improve the shear resistance of the cylinder 1. Under shear force, the stiffeners 6 increase the shear force transmission path, improving the shear strength of the cylinder 1. The straight, continuous stiffeners 6 help connect different parts of the cylinder 1 into a whole, enhancing the integrity and continuity of the structure, which is particularly important for improving the seismic performance of the structure. The straight-lined stiffeners 6 are easier to install and position during construction, which improves construction efficiency and reduces construction difficulty.

[0069] In this embodiment, the reinforcing rib 6 extends in the same direction as the axis of the cylinder 1.

[0070] The straight-lined reinforcing rib 6 has better connectivity.

[0071] Specifically, the stiffeners 6 are arranged along the axis of the cylinder 1, directly resisting loads along the axial direction, such as axial compression or tensile force, thereby improving the axial load-bearing capacity of the cylinder 1. The longitudinally arranged stiffeners 6 improve the overall stability of the cylinder 1, especially under compressive loads, preventing local or overall buckling. The axially arranged stiffeners 6 help distribute loads more evenly, reducing local stress concentration and improving the durability and reliability of the structure. Under horizontal loads such as earthquakes, the longitudinally arranged stiffeners 6 improve the seismic performance of the cylinder 1, reducing structural damage caused by earthquakes.

[0072] In this embodiment, the anchoring ring 5 has a thickness of 3mm and a bottom width of 4mm. This size of anchoring ring 5 can save more material while ensuring strength.

[0073] The reinforcing rib of this size 6 can save more material while ensuring strength.

[0074] In this embodiment, the thickness of the reinforcing rib 6 is 3mm and the bottom width of the reinforcing rib 6 is 4mm. The reinforcing rib 6 of this size can save more material while ensuring strength.

The reinforcing rib 6 passes through the anchoring ring 5 and is distributed along the length of the cylinder 1.

[0078] Grouting port 2 is used for grouting, and grout outlet 3 is used for grout discharge. The circumferential anchor strengthens the strength of cylinder 1. The reinforcing rib 6 not only strengthens the cylinder 1 but also the circumferential anchor, significantly increasing the strength of the outer wall of the entire cylinder 1. Therefore, even with an inner straight cylinder wall, grouting can be carried out effectively, achieving rapid and full grouting, thus strengthening the sleeve body. This solves the problems of slow and incomplete grouting during construction. Simultaneously, through innovative structural modifications, it strengthens the cylinder structure and improves the performance of the grouting sleeve.

[0079] In this embodiment, there are several anchor rings 5, and the several anchor rings 5 ​​are distributed along the length direction of the outer cylinder wall 9.

[0081] In this embodiment, six anchoring rings 5 ​​are provided, three of which are close to the grouting port 2 and three of which are close to the grout outlet 3.

[0082] Since both the grouting port 2 and the grouting outlet 3 require grout to enter and exit, they are subjected to greater stress. Therefore, anchoring rings 5 ​​are installed at the grouting port 2 and the grouting outlet 3 to achieve better reinforcement.
