Detachable connecting component for modular pavement

Abstract

The detachable connecting component comprises an upper ring sleeve and a lower ring sleeve, the upper ring sleeve is used for butt joint of round pipe fittings on the two sides of the modular pavement, the lower ring sleeve is arranged on the upper ring sleeve, an upper eccentric plummer block is eccentrically arranged on the lower ring sleeve, a lower eccentric shaft hole is eccentrically formed in the lower ring sleeve, and the upper eccentric plummer block is rotatably arranged in the lower eccentric shaft hole in a penetrating mode. The upper ring sleeve and the lower ring sleeve are staggered within 10 mm and can be adjusted in a self-adaptive mode through rotation, when the lower amplitude of a butt joint area is staggered due to construction errors during modular pavement round pipe butt joint, the upper ring sleeve and the lower ring sleeve can be adjusted in a self-adaptive mode to be in butt joint, and due to the fact that the upper limit value of the construction errors of the modular pavement is 10 mm, the butt joint area can be adjusted in a self-adaptive mode. When the upper ring sleeve and the lower ring sleeve are still not in butt joint after rotation dislocation, it shows that the construction error is large, rectification processing needs to be carried out on the area to be changed, and the connecting components synchronously play a role of a testing fixture.

Description

Technical Field

[0001] The utility model relates to the field of building accessories, in particular to a detachable connecting member for modular pavement. Background Art

[0002] Modular pavement is a pavement structure constructed by using modular components or units. Modular pavement means that the pavement is divided into multiple independent and standardized modules or units, and these modules are connected to each other through specific connection methods (such as grooves, piles, etc.) to form an overall pavement structure;

[0003] In the prior art, when the round pipes on both sides of the modular pavement are butt-jointed, they are directly sleeved and connected through a straight sleeve. Due to construction errors of the pavement, the situation where the straight sleeve cannot be accurately aligned and sleeved often occurs, and welding can only be carried out at the butt-jointed area to repair leaks. At the same time, when adjacent modular pavements are in use, there is often a settlement height difference. The round pipe butt-jointed area of the modular pavement is misaligned with the settlement, resulting in damage to the sleeved connection area. Summary of the Utility Model

[0004] The purpose of the utility model is to solve any of the above technical problems, and thus a detachable connecting member for modular pavement is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A detachable connecting member for modular pavement, including an upper ring sleeve for butt-jointing round pipe fittings on both sides of the modular pavement and a lower ring sleeve arranged thereon. An upper eccentric shaft platform is eccentrically arranged on the lower ring sleeve, and a lower eccentric shaft hole is eccentrically arranged on the lower ring sleeve. The upper eccentric shaft platform rotates through the lower eccentric shaft hole.

[0006] Further, the upper ring sleeve is cylindrical. An upper eccentric shaft platform in the shape of a T-shaped round platform is eccentrically arranged on the bottom surface of the upper ring sleeve. The offset dimension between the upper eccentric shaft platform and the center line of the upper ring sleeve is 5 mm. A side avoidance groove penetrating through to the inner wall is arranged on the circumferential side wall of the upper ring sleeve. A telescopic joint is arranged on the circumferential ring in the middle section of the side avoidance groove. A bolt hole with a countersunk head hole at one end and a threaded hole at the other end is arranged on the side of the telescopic joint. The lower ring sleeve is rotatably sleeved on the upper ring sleeve.

[0007] Further, the lower ring sleeve is cylindrical. A lower eccentric shaft hole in the shape of a T-shaped round groove is eccentrically arranged on the bottom surface of the lower ring sleeve. The offset dimension between the lower eccentric shaft hole and the center line of the lower ring sleeve is 5 mm. A side avoidance groove penetrating through to the inner wall is arranged on the circumferential side wall of the lower ring sleeve. A telescopic joint is arranged on the circumferential ring in the middle section of the side avoidance groove. A bolt hole with a countersunk head hole at one end and a threaded hole at the other end is arranged on the side of the telescopic joint. The upper eccentric shaft platform rotates through the lower eccentric shaft hole.

[0008] The beneficial effects of the utility model are:

[0009] The offset dimension between the upper eccentric shaft platform of the upper ring sleeve and the center line of the upper ring sleeve is 5 mm, and the offset dimension between the eccentric shaft hole of the lower ring sleeve and the center line of the lower ring sleeve is 5 mm. The upper eccentric shaft platform rotates and passes through the lower eccentric shaft hole. When the upper and lower ring sleeves are misaligned within 10 mm, they can be adaptively adjusted by rotation. When modular pavement round pipes are butt-jointed and there is a downward misalignment in the butt-joint area due to construction errors, the upper and lower ring sleeves can be adaptively adjusted for butt-joint. Since the upper limit value of the construction error of modular pavement is 10 mm, when the upper and lower ring sleeves still cannot be butt-jointed after rotational misalignment, it indicates that the construction error is large and the area needs to be rectified. The connecting component also serves as a gage synchronously. When the modular pavement is in use and there is slight settlement in some areas due to vehicle rolling, the upper and lower ring sleeves can be adaptively adjusted to avoid the occurrence of torsion deformation and breakage at the butt-joint of the round pipes due to slight settlement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1 to 5 ;

[0017] This embodiment provides a detachable connecting component for modular pavement, including an upper ring sleeve 1 for butt-jointing round pipe components on both sides of the modular pavement and a lower ring sleeve 2 arranged thereon. The lower ring sleeve 2 is eccentrically provided with an upper eccentric shaft platform 11, and the lower ring sleeve 2 is eccentrically provided with a lower eccentric shaft hole 21. The upper eccentric shaft platform 11 rotates and passes through the lower eccentric shaft hole 21.

[0018] Preferably, the upper ring sleeve 1 is cylindrical. An upper eccentric shaft platform 11 in the shape of a T-shaped frustum is eccentrically arranged on the bottom surface of the upper ring sleeve 1. The offset dimension between the center line of the upper eccentric shaft platform 11 and the upper ring sleeve 1 is 5 mm. A side avoidance groove 12 penetrating through to the inner wall is arranged on the circular side wall of the upper ring sleeve 1. A telescopic joint 13 is arranged on the middle section of the circular ring of the side avoidance groove 12. A bolt hole 14 with a countersunk hole at one end and a threaded hole at the other end is arranged on the side of the telescopic joint 13. The lower ring sleeve 2 is rotatably sleeved on the upper ring sleeve 1.

[0019] In a specific embodiment, the offset dimension between the center line of the upper eccentric shaft platform 11 of the upper ring sleeve 1 and the upper ring sleeve 1 is 5 mm, and the offset dimension between the center line of the eccentric shaft hole 21 of the lower ring sleeve 2 and the lower ring sleeve 2 is 5 mm. The upper eccentric shaft platform 11 is rotatably inserted into the lower eccentric shaft hole 21. The upper ring sleeve 1 and the lower ring sleeve 2 can be adaptively adjusted by rotation within a misalignment of 10 mm.

[0020] Preferably, the lower ring sleeve 2 is cylindrical. A lower eccentric shaft hole 21 in the shape of a T-shaped circular groove is eccentrically arranged on the bottom surface of the lower ring sleeve 2. The offset dimension between the center line of the lower eccentric shaft hole 21 and the lower ring sleeve 2 is 5 mm. A side avoidance groove 12 penetrating through to the inner wall is arranged on the circular side wall of the lower ring sleeve 2. A telescopic joint 13 is arranged on the middle section of the circular ring of the side avoidance groove 12. A bolt hole 14 with a countersunk hole at one end and a threaded hole at the other end is arranged on the side of the telescopic joint 13. The upper eccentric shaft platform 11 is rotatably inserted into the lower eccentric shaft hole 21.

[0021] In a specific embodiment, since the upper limit value of the modular pavement construction error is 10 mm, when the upper ring sleeve 1 and the lower ring sleeve 2 still cannot be docked after being rotated and misaligned, it indicates that the construction error is relatively large and the area needs to be rectified. The connecting member also serves as a checking tool.

[0022] In a specific embodiment, when the modular pavement is in use and some areas are slightly settled due to vehicle rolling, the upper ring sleeve 1 and the lower ring sleeve 2 can be adaptively adjusted within a reasonable range of 10 mm, avoiding the situation of torsional deformation and damage at the circular tube docking due to slight settlement.

[0023] In a specific embodiment, when the settlement misalignment difference in the vehicle rolling area exceeds the safety value of 10 mm during the use of the modular pavement, the upper ring sleeve 1 and the lower ring sleeve 2 are damaged. The inspection and maintenance personnel can directly observe the working state of the upper ring sleeve 1 and the lower ring sleeve 2 to accurately find the area of pavement settlement for targeted repair.

[0024] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
