[0023] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] See also Figures 1 to 6The utility model provides a pipeline threading auxiliary structure including a first pipe sleeve 10 and a second pipe sleeve 20 that are cross-connected. Specifically, the first pipe sleeve 10 and the second pipe sleeve 20 are connected by a connecting piece 30, and the first pipe sleeve 10 and the second pipe sleeve 20 can rotate around the connecting piece 30; the first pipe sleeve 10 and the second pipe sleeve 20 are both used to limit the threading pipe; specifically, the first pipe sleeve 10 is used to be sleeved on the first threading pipe 40, and the second pipe sleeve 20 is used to be sleeved on the second threading pipe 50, and the first threading pipe 40 and the second threading pipe 50 are cross-arranged, and the crossing angle of the first pipe sleeve 10 and the second pipe sleeve 20 is consistent with the crossing angle of the first threading pipe 40 and the second threading pipe 50; wherein, the first threading pipe 40 and the second threading pipe 50 are respectively arranged in the tied steel bar structure.

[0027] When the first pipe sleeve 10 is sleeved on the first threading tube 40, the second pipe sleeve 20 is synchronously adjusted according to the placement angle between the second threading tube 50 and the first threading tube 40 in the tied steel bar structure, so that the second threading tube 50 can pass through the second pipe sleeve 20 stably. At this time, the second threading tube 50 can only rotate around the position of the second pipe sleeve 20 as the center, and will not slide on the extension path of the first threading tube 40, effectively improving the stability of the mutually crossed threading tubes in the tied steel bar structure, thereby preventing the threading tubes from being damaged by construction workers due to arbitrary displacement, thereby improving the installation quality and service life of the threading tubes; in this embodiment, since the threading tubes have a large length, there is a great obstacle when performing the rotation operation around the position of the second pipe sleeve 20 as the center, that is, after the second threading tube 50 passes through the second pipe sleeve 20, the intersection angle of the first pipe sleeve 10 and the second pipe sleeve 20 of the pipeline threading auxiliary structure will no longer change significantly.

[0028] During the construction process, when traditional PVC pipes are arranged crosswise and overlapped, large gaps will appear between the PVC pipes. When the steel bars are tied, the distance between the upper and lower layers of steel bars will increase due to the gaps between the PVC pipes, resulting in the steel bar protective layer becoming smaller when the concrete is poured, exceeding the standard value range allowed by the specification. The present invention adopts the above method to solve this problem.

[0029] That is, the first threading tube 40 is passed through the first pipe sleeve 10, and the second threading tube 50 is passed through the second pipe sleeve 20. Since the first pipe sleeve 10 and the second pipe sleeve 20 are fitted together by the connecting piece 30, during the construction process, the first threading tube 10 and the second threading tube 20 will also be closely set when they cross and overlap, effectively avoiding the first threading tube 10 and the second threading tube 20 not being limited by the first pipe sleeve 10 and the second pipe sleeve 20, resulting in a large gap between the first threading tube 10 and the second threading tube 20, thereby avoiding the spacing between the upper and lower layers of steel bars from increasing due to the increase in the gap between the first threading tube 10 and the second threading tube 20 when the steel bars are tied. Finally, the steel bar protective layer formed by the tied steel bars during concrete pouring will be within the standard value range allowed by the specification, effectively improving the quality of construction.

[0030] Furthermore, when there is a third wire threading tube arranged in the tied steel bar structure, at this time, it is necessary to add at least one pipe threading auxiliary structure of the utility model. The specific operation is: when a pipe threading auxiliary structure is added, the second pipe threading auxiliary structure is placed at the intersection of the second wire threading tube 50 and the third wire threading tube (not shown in the figure), and the first pipe sleeve 10 of the second pipe threading auxiliary structure is sleeved on the second wire threading tube 50 as needed, and the third wire threading tube passes through the second pipe sleeve 20 of the second pipe threading auxiliary structure, thereby completing the stable arrangement of the third wire threading tube in the tied steel bar structure. At this time, the third wire threading tube can only rotate around the position of the second pipe sleeve 20 as the center, and will not slide on the extension path of the second wire threading tube 50, effectively improving the stability of the mutually crossed wire threading tubes in the tied steel bar structure, thereby avoiding the wire threading tubes from being damaged by construction workers due to arbitrary displacement, thereby improving the installation quality and service life of the wire threading tubes.

[0031] When two pipeline threading auxiliary structures are added, since the first pipeline threading auxiliary structure is already provided at the intersection of the first threading tube 40 and the second threading tube 50, the second pipeline threading auxiliary structure is provided at the intersection of the second threading tube 50 and the third threading tube, and the third pipeline threading auxiliary structure is provided at the intersection of the first threading tube 40 and the third threading tube; wherein, the first pipe sleeve 10 of the second pipeline threading auxiliary structure is sleeved on the second threading tube 50 as needed, and the third threading tube passes through the second pipe sleeve 20 of the second pipeline threading auxiliary structure, thereby completing the stable arrangement of the third threading tube in the tied steel bar structure; the first pipe sleeve 10 of the third pipeline threading auxiliary structure is sleeved on the first threading tube as needed On the wire pipe 40, the third wire pipe passes through the second pipe sleeve 20 of the third pipe wire threading auxiliary structure, thereby further completing the stable arrangement of the third wire pipe in the tied steel bar structure; at this time, the first pipe wire threading auxiliary structure, the second pipe wire threading auxiliary structure and the third pipe wire threading auxiliary structure form a triangular arrangement relationship. Based on the stability of the triangle, the positions and extension directions of the first wire pipe 40, the second wire pipe 50 and the third wire pipe will no longer change, further effectively improving the stability of the crossed wire pipes in the tied steel bar structure, thereby avoiding the wire pipes from being damaged by construction workers due to arbitrary displacement, thereby improving the installation quality and service life of the wire pipes.

[0032] During the construction process, after the first threading tube 40 is placed horizontally in the tied steel bar structure, when the second threading tube 50 needs to be placed vertically or obliquely in the tied steel bar structure, the first threading tube 40 and the second threading tube 50 are in different planes, that is, the second threading tube 50 needs to be placed above the first threading tube 40 to complete the arrangement requirements of the second threading tube 50 in the tied steel bar structure; at this time, if the second threading tube 50 is directly placed above the first threading tube 40, the movement of the second threading tube 50 is not restricted. During the placement of the second threading tube 50, the second threading tube 50 can move in a larger space range above the first threading tube 40, causing the placement of the second threading tube 50 to be inconsistent with expectations, and the disorderly placement of the threading tubes is more likely to be stepped on and damaged by construction workers; for this reason, in order to improve the stability of the placement of the crossed threading tubes in the tied steel bar structure, the present invention adopts the following method to solve the problem.

[0033] The pipeline threading auxiliary structure of the present invention is placed at the intersection of the first threading tube 40 and the second threading tube 50 . The first pipe sleeve 10 is sleeved on the first threading tube 40 , and the second pipe sleeve 20 is sleeved on the second threading tube 50 .

[0034] When the first pipe sleeve 10 is sleeved on the first wire tube 40, the rotation angle of the second pipe sleeve 20 is adjusted according to the intersection angle between the second wire tube 50 and the first wire tube 40, so that the second wire tube 50 is set through the second pipe sleeve 20. The second wire tube 50 can only rotate around the position of the second pipe sleeve 20 and will not slide on the extension path of the first wire tube 40, effectively improving the stability of the crossed wire tubes in the tied steel bar structure, thereby preventing the wire tubes from being damaged by construction workers due to arbitrary displacement, thereby improving the installation quality and service life of the wire tubes.

[0035] In one embodiment, the first pipe sleeve 10 and the second pipe sleeve 20 are both semi-cylindrical in structure, which facilitates the limiting of the wire threading tube; and the first pipe sleeve 10 is designed to be semi-cylindrical in structure, which helps to ensure the stability of the placement of the first pipe sleeve 10 and facilitates the formation of a stable support effect for the second pipe sleeve 20.

[0036] In order to further improve the limiting effect of the wire threading tube, the present invention also adopts the following structure to solve the problem.

[0037] In one embodiment, a limiting band 60 is provided on the second pipe sleeve 20 , and the limiting band 60 is used to limit the second threading tube 50 in the second pipe sleeve 20 .

[0038] Specifically, the limiting belt 60 is respectively arranged at the two ends of the second pipe sleeve 20. Through the limiting effect of the two ends of the second pipe sleeve 20, the second wire threading tube 50 is effectively and firmly limited in the second pipe sleeve 20; when in use, the limiting belt 60 can be bent into a semicircular ring structure, so that the limiting belt 60 and the second pipe sleeve 20 are connected together through a locking structure.

[0039] Alternatively, the limiting belt 60 can also be set in the middle of the second pipe sleeve 20 as needed. When in use, the limiting belt 60 can be bent into a semicircular ring structure, so that the limiting belt 60 and the second pipe sleeve 20 are connected together through a locking structure; this design has a slightly smaller limiting effect on the second wire threading tube 50 than the limiting effect on the second wire threading tube 50 when the limiting belt 60 is respectively set at the two ends of the second pipe sleeve 20.

[0040] Alternatively, the limiting belt 60 can also be set at the two ends and the middle of the second pipe sleeve 20 as needed. When in use, the limiting belt 60 can be bent into a semicircular ring structure, so that the limiting belt 60 and the second pipe sleeve 20 are connected together through a locking structure; this design further enhances the limiting effect of the second wire threading tube 50.

[0041] Furthermore, undercuts 21 are respectively provided on both sides of the two ends of the second pipe sleeve 20, and buckle grooves 61 are respectively provided at both ends of the limiting belt 60. The undercuts 21 are clamped in the buckle grooves 61, thereby completing the stable connection effect between the limiting belt 60 and the second pipe sleeve 20, and then effectively limiting the second threading tube 50 firmly in the second pipe sleeve 20; in this embodiment, the limiting belt 60 is a plastic sheet structure with a certain cross-sectional width, so that the fitting area with the threading tube in the second pipe sleeve 20 is larger, and the second threading tube 50 can be limited in the second pipe sleeve 20 without causing cutting-type damage to the second threading tube 50; in addition, the locking structure is a combination of the undercut structure provided at both ends of the second pipe sleeve 20 and the buckle groove structure provided on the limiting belt 60.

[0042] In this embodiment, the undercut 21 structures provided at both ends of the second pipe sleeve 20 are block structures with an "L"-shaped cross-section formed by bending and extending from both sides of the two ends of the second pipe sleeve 20, wherein the limiting belt 60 has a certain elastic property, and the second pipe sleeve 20 is sleeved on the second wire threading tube 50. When the two ends of the limiting belt 60 are locked on the second pipe sleeve 20, the limiting belt 60 completes the connection effect with the second pipe sleeve 20 in a stretched state; the opening of the undercut 21 structure of the second pipe sleeve 20 is designed to face downward, so that the buckle groove 61 structure opened at both ends of the limiting belt 60 is difficult to detach from the undercut 21 structure on the second pipe sleeve 20, thereby ensuring the stable connection effect between the limiting belt 60 and the second pipe sleeve 20.

[0043] Alternatively, buckle grooves are respectively provided on both sides of the two ends of the second pipe sleeve 20, and undercuts are respectively provided at both ends of the limiting belt 60, which are clamped in the buckle grooves, thereby completing the stable connection effect between the limiting belt 60 and the second pipe sleeve 20, and then effectively limiting the second threading tube 50 firmly in the second pipe sleeve 20; in this embodiment, the limiting belt 60 is a plastic sheet structure with a certain cross-sectional width, so that the fitting area with the threading tube in the second pipe sleeve 20 is larger, and the second threading tube 50 can be limited in the second pipe sleeve 20 without causing cutting-type damage to the second threading tube 50; in addition, the locking structure is a combination of the buckle groove structure provided at both ends of the second pipe sleeve 20 and the undercut structure provided on the limiting belt 60.

[0044] In this embodiment, the inverted structures provided at both ends of the limiting belt 60 are block structures with an "L"-shaped cross-section formed by bending and extending from both sides of the two ends of the limiting belt 60, wherein the limiting belt 60 has a certain elastic property, and the second pipe sleeve 20 is placed on the second wire threading tube 50. When the two ends of the limiting belt 60 are locked on the second pipe sleeve 20, the limiting belt 60 completes the connection effect with the second pipe sleeve 20 in a stretched state; the opening of the inverted structure of the limiting belt 60 is designed to face upward, so that the inverted structures protruding at both ends of the limiting belt 60 are difficult to detach from the buckle groove structure on the second pipe sleeve 20, thereby ensuring the stable connection effect between the limiting belt 60 and the second pipe sleeve 20.

[0045] In other embodiments, alternatively, the limiting belt 60 can be designed as an elastic ring belt such as a rubber belt, and the limiting belt 60 is arranged around the second pipe sleeve 20 to limit the second threading tube 50 in the second pipe sleeve 20.

[0046] In one embodiment, an arc-shaped opening 70 is opened in the middle of both sides of the first pipe sleeve 10 and the second pipe sleeve 20, so that most of the structures of the first threading tube 40 and the second threading tube 50 passed through the first pipe sleeve 10 and the second pipe sleeve 20 can be exposed outside the pipeline threading auxiliary structure of the utility model, so that the structural status of the threading tube at the intersection of the first threading tube 40 and the second threading tube 50 can be checked more efficiently, so as to find out whether the threading tube is damaged in the first time and facilitate the repair and maintenance of the threading tube.

[0047] In one embodiment, the connecting piece 30 is passed through the middle of the bottom end of the first pipe sleeve 10 and the bottom end of the second pipe sleeve 20, so that the connection between the first pipe sleeve 10 and the second pipe sleeve 20 is more beautiful; the cross-section of the connecting piece 30 is an I-shaped structure, and the connecting piece 30 includes a connecting rod 31 and a limiting cap 32 arranged at both ends of the connecting rod 31. The connecting rod 31 passes through the first pipe sleeve 10 and the second pipe sleeve 20, and the two limiting caps 32 are respectively protruded in the cavities of the first pipe sleeve 10 and the second pipe sleeve 20, so that the connection between the first pipe sleeve 10 and the second pipe sleeve 20 is more stable. When the first pipe sleeve 10 is sleeved on the first threading tube 40, the second pipe sleeve 20 rotates around the connecting rod 31 as an axis to adapt to the arrangement direction of the second threading tube 50 in the tied steel bar structure, thereby completing the sleeve operation of the second threading tube 50; wherein, the cavity of the first pipe sleeve 10 is used for the first threading tube 40 to pass through, and the cavity of the second pipe sleeve 20 is used for the second threading tube 50 to pass through.

[0048] When the present invention is used specifically, when there are only the first threading tube 40 and the second threading tube 50 in the tied steel bar structure, at this time, it is only necessary to place the pipeline threading auxiliary structure of the present invention at the intersection of the first threading tube 40 and the second threading tube 50. The first pipe sleeve 10 of the pipeline threading auxiliary structure of the present invention is sleeved on the first threading tube 40. When the first pipe sleeve 10 is sleeved on the first threading tube 40, the rotation angle of the second pipe sleeve 20 is adjusted according to the intersection angle between the second threading tube 50 and the first threading tube 40, so that the second threading tube 50 is set through the second pipe sleeve 20. At this time, the second threading tube 50 can only be installed with the second pipe sleeve 20. The second threading tube 50 is rotated around the position of the second sleeve 20 without sliding on the extension path of the first threading tube 40. Since the second threading tube 50 has a large length, it is greatly hindered when performing the rotation operation centered on the position of the second sleeve 20. That is, after the second threading tube 50 passes through the second sleeve 20, the intersection angle of the first sleeve 10 and the second sleeve 20 of the pipeline threading auxiliary structure will no longer change significantly, effectively improving the stability of the mutually crossed threading tubes in the tied steel bar structure, thereby avoiding the threading tubes from being damaged by construction workers due to arbitrary displacement, thereby improving the installation quality and service life of the threading tubes.

[0049] When there are the first threading tube 40, the second threading tube 50 and the third threading tube in the tied steel bar structure, at this time, it is necessary to set up at least two pipe threading auxiliary structures of the present invention. In order to improve the stability of the mutually crossed threading tubes in the tied steel bar structure, taking the setting of three pipe threading auxiliary structures of the present invention as an example, they are defined as the first pipe threading auxiliary structure, the second pipe threading auxiliary structure and the third pipe threading auxiliary structure, wherein the first pipe threading auxiliary structure is set at the intersection of the first threading tube 40 and the second threading tube 50, the second pipe threading auxiliary structure is set at the intersection of the second threading tube 50 and the third threading auxiliary structure. At the intersection of the three wire threading tubes, the third pipe threading auxiliary structure is arranged at the intersection of the first wire threading tube 40 and the third wire threading tube. At this time, the first pipe threading auxiliary structure, the second pipe threading auxiliary structure and the third pipe threading auxiliary structure form a triangular arrangement relationship. Based on the stability of the triangle, the positions and extension directions of the first wire threading tube 40, the second wire threading tube 50 and the third wire threading tube will no longer change, further effectively improving the stability of the mutually intersecting wire threading tubes in the tied steel bar structure, thereby preventing the wire threading tubes from being damaged by construction workers due to arbitrary displacement, thereby improving the installation quality and service life of the wire threading tubes.

[0050] To sum up, the utility model provides a pipeline threading auxiliary structure by setting a first pipe sleeve 10 for being sleeved on the first threading tube 40, and cooperating with setting a second pipe sleeve 20 for being sleeved on the second threading tube 50. When the first pipe sleeve 10 is sleeved on the first threading tube 40, the rotation angle of the second pipe sleeve 20 is adjusted according to the intersection angle between the second threading tube 50 and the first threading tube 40, so that the second threading tube 50 is set through the second pipe sleeve 20. The second threading tube 50 can only rotate with the position of the second pipe sleeve 20 as the center, and will not slide on the extension path of the first threading tube 40, effectively improving the stability of the mutually crossed threading tubes in the tied steel bar structure, thereby preventing the threading tubes from being damaged by construction workers due to arbitrary displacement, thereby improving the installation quality and service life of the threading tubes.

[0051] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
