Technical Field

The present application relates to connection and welding technology, and in particular, to a connection structure.

Background

At present, the connection between prefabricated building components is mainly realized by three modes of steel bar bundling, welding and steel bar grouting sleeve. However, the three connection modes are complex or high in required precision in the construction process, so that the efficiency of site construction is limited and high labor cost is brought.

According to a first aspect of embodiments of the present application, there is provided a connection structure, including: an outer sleeve and an inner leg, respectively located in different parts, the inner leg being insertable into the outer sleeve to form a connecting cavity for filling a connecting material to connect the different parts; the outer sleeve being elongate and having a closed cross-sectional profile, the outer sleeve being formed by welding at least two sleeve members; any of the sleeve members has at least in part an open cross-sectional profile, with the inner wall of the sleeve member welded with an inner shear structure.

By adopting the concept of 'using the sleeve to replace the steel bar to bind or the grouting sleeve to complete the part connection' in the embodiment of the application, the complex construction process and labor cost of steel bar binding and steel bar welding and the higher butt joint precision requirement of the steel bar grouting sleeve are avoided. In order to improve the shear strength of the connecting structure, the embodiment of the application further adopts the concept of forming an outer sleeve with a closed cross-section profile through the combination of sleeve components with an open cross-section profile, and does not directly try to weld the inner shear structure in the barrel of the outer sleeve, but firstly welds the inner wall of the sleeve component with the open cross-section profile, and as the cross-section profile is open, a welding gun does not need to go deep into the barrel as the outer sleeve in the welding process and is difficult to finish welding, and the welding work is directly finished in an open space; and then, the sleeve part welded with the shearing structure is welded to form an outer sleeve, and the two-wheel welding is not limited by the structure, so that the welding can be successfully completed.

Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of exemplary embodiments of the present application is given with reference to the accompanying drawings, and it is apparent that the described embodiments are only some of the embodiments of the present application and not exhaustive of all the embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.

As a first aspect of the present application, fig. 1, 2 and 3 illustrate an exemplary connection structure. The connection structure includes:

an outer sleeve 1 and an inner leg 2, respectively located in different parts, the inner leg 2 being insertable into the outer sleeve 1 to form a connecting cavity for filling a connecting material to connect the different parts;

the outer sleeve 1 is elongated and has a closed cross-sectional profile, the outer sleeve 1 being formed by welding at least two sleeve parts 11;

any sleeve member has an open cross-sectional profile, at least in part, and an inner shear structure is welded to the inner wall of the sleeve member.

By adopting the concept of 'using the sleeve to replace the steel bar to bind or the grouting sleeve to complete the part connection' in the embodiment of the application, the complex construction process of steel bar binding and steel bar welding is avoided, and the requirement on labor cost and the higher butt joint precision of the steel bar grouting sleeve is avoided. In order to improve the shear strength of the connecting structure, the embodiment of the application further adopts the concept of forming an outer sleeve with a closed cross-section profile through the combination of sleeve components with an open cross-section profile, and does not directly try to weld the inner shear structure in the barrel of the outer sleeve, but firstly welds the inner wall of the sleeve component with the open cross-section profile, and as the cross-section profile is open, a welding gun does not need to go deep into the barrel as the outer sleeve in the welding process and is difficult to finish welding, and the welding work is directly finished in an open space; and then, the sleeve part welded with the shearing structure is welded to form an outer sleeve, and the two-wheel welding cannot be completed due to the fact that the two-wheel welding is not limited by the structure. The problem that different parts are hoped to be connected in a sleeving manner, but the inner wall of the outer sleeve cannot be welded with a shearing structure, so that the problem cannot be solved is further solved.

It should be noted that the outer sleeve 1 and the inner leg 2 are located in different components, and the present application is not limited to the specific types of the components. By way of example, the different components herein may be building components, such as steel columns within walls, or mechanical equipment components, such as robotic arms, etc.

Under the condition that different parts are steel columns in the wall body, the steel columns which are located in the wall body at the positions corresponding to adjacent floors and used for connection can be particularly used for being connected, and the requirements of connection between the upper layer steel columns and the lower layer steel columns exist, so that the connection structure can be used for connection. As an implementation manner, the outer sleeve 1 may be located at the bottom end of the upper steel column, and the corresponding inner leg 2 is located at the top end of the lower steel column, so as to implement a socket joint fit between the two. Of course, the two positions can be interchanged, the outer sleeve 1 is positioned at the top end of the lower steel column, and the inner column 2 is positioned at the bottom end of the upper steel column. These two implementations do not affect the achievement of this objective of the connection.

When the connection structure provided by the application is specifically applied to other types of components except the steel column in the wall, a person skilled in the art can select the setting position according to the specific situation by referring to the setting mode, and the details are not repeated here.

By way of example, fig. 1 shows a specific structure of an inner leg 2. The inner leg 2 is elongated and may extend wholly or partially into the outer sleeve 1. As an implementation manner, after the inner leg 2 extends into the outer sleeve 1, a connection cavity is formed between the inner wall of the outer sleeve 1 and the outer wall of the inner leg 2, and a filling material such as concrete or glue is poured into the connection cavity to connect the inner leg 2 and the outer sleeve 1. The pouring glue can be epoxy pouring glue or organic silicon pouring glue according to the connection strength requirement, and the application is not particularly limited. As another implementation manner, after the inner leg 2 extends into the outer sleeve 1, besides filling materials such as concrete or glue, a connecting piece, such as a bolt, a self-tapping screw, or the like, may be used to further fix the inner leg 2 and the outer sleeve 1.

The inner leg 2 may be obtained by cutting a section bar or by welding a plurality of steel plates, and the present application is not limited to a specific manufacturing method and a specific structural style of the inner leg 2, and may extend into the outer sleeve 1 entirely or partially.

Fig. 1, 2 and 3 also show a specific construction of the outer sleeve 1, by way of example. The outer sleeve 1 is elongated and may accommodate all or part of the inner leg 2.

It should be noted that the outer sleeve 1 has a closed cross-sectional profile, and a polygonal profile such as a rectangle, a hexagon, a heptagon, etc. may be selected according to practical situations, and the specific style of the cross-sectional profile is not limited in the present application. Unlike the outer sleeve 1, the inner leg 2 may have a closed cross-sectional profile or an open cross-sectional profile, and the cross-sectional profile of the inner leg 2 is not particularly limited herein, and may be rectangular, hexagonal, heptagonal, or the like.

There is a need to improve the shear strength of the connection structure due to insufficient bonding strength of the filling material or large shearing force applied to the connection structure in use. In order to improve the shear strength of the connecting structure, the inner wall of the outer sleeve 1 is further provided with the inner shear structure 12, and the shear strength of the connecting structure can be improved through the cooperation of the inner shear structure 12 and the filling material.

It should be noted that, the arrangement manner and the metal material of the inner shear structure 12 may be flexibly selected according to the specific shear strength requirement or cost requirement, which is not limited in this application. For example, steel bars that are disposed at intervals along the insertion direction of the inner leg 2 and are parallel to each other may be selected as the inner shear structure 12, or iron bars that are disposed at intervals along the insertion direction of the inner leg 2 but are staggered with each other may be selected as the inner shear structure 12.

The inner shear structure 12 is connected with the outer sleeve 1 by welding, which is a connection mode capable of meeting the use strength, but the welding gun is difficult to extend into the inner portion of the outer sleeve 1 and the welding position is difficult to observe. For this purpose, the present application further adopts a manner of forming the outer sleeve 1 by welding the sleeve member 11, avoiding directly welding the inner shear structure 12 inside the outer sleeve 1, but firstly completing the welding of the inner shear structure 12 on the inner wall of the sleeve member 11, and then welding the sleeve member 11 having the inner shear structure 12 welded thereto to form the outer sleeve 1.

It should be noted that, the number of the sleeve members 11 to be welded to form the outer sleeve 1 may be determined according to the actual use environment. For convenience of description, the present application will be described below by taking only two sleeve members 11 as an example of forming the outer sleeve 1 by welding, and not as a limitation on the implementation of the present application. Further, in order to distinguish between the two sleeve members 11, one of them is named sleeve member 11a and the other is named sleeve member 11b.

Since the outer sleeve 1 is elongated, the welding area between the sleeve member 11a and the sleeve member 11b is relatively long, which is susceptible to structural deformation due to welding during the welding process. In order to prevent the deformation of the structure, the present application further welds the deformation-resistant structure 13 at the welding position between the barrels of the inner walls of the sleeve member 11a and the sleeve member 11b, respectively. The inter-cylinder welding position refers to a position where the sleeve member 11a is used to weld with the sleeve member 11b or a position where the sleeve member 11b is used to weld with the sleeve member 11 a. Further, in order to distinguish the deformation-resistant structure 13 of the inner wall of the sleeve member 11a from the inner wall of the sleeve member 11b, one of them is named as deformation-resistant structure 13a, and the other one is named as deformation-resistant structure 13b.

Here, the welding of the deformation-resistant structure 13a of the inner wall of the sleeve member 11a will be described as an example: firstly, welding one part of the deformation-resistant structure 13a on the inner wall of the sleeve part 11a, and exposing the other part of the deformation-resistant structure outside; then, the exposed portion of the deformation preventing structure 13a is welded to the inner wall of the sleeve member 11b, so that the deformation preventing structure 13a is welded to the sleeve member 11a and the sleeve member 11b. Since the deformation-resistant structure 13a is welded to the welding position of the sleeve member 11a and the sleeve member 11b, the structural strength of the welding position is enhanced, and when the sleeve member 11a and the sleeve member 11b are welded, the stress generated during the welding can be canceled.

It should be noted that, the deformation-resistant structure 13 may be welded to the inner wall of each sleeve member before the sleeve members 11a and 11b are welded, or may be welded to the inner wall of one of the sleeve members before the sleeve members 11a and 11b are welded according to practical situations, which is not limited in this application.

It should be noted that the number of the deformation-resistant structures is related to the lengths of the sleeve members 11a and 11b in the insertion direction of the inner leg 2. When the length of the sleeve member 11a and the sleeve member 11b in the insertion direction of the inner leg 2 is long, a plurality of deformation-resistant structures need to be provided; conversely, fewer deformation-resistant structures may be provided. However, how many anti-deformation structures should be provided in the implementation process of the present application can be determined according to practical situations, which is not particularly limited in the present application.

As an implementation, when a plurality of deformation-resistant structures are provided, the plurality of deformation-resistant structures may be selected to be disposed at equidistant intervals along the insertion direction of the sleeve member 11a or the sleeve member 11b. As a further embodiment, a plurality of deformation-resistant structures may also be arranged at non-equidistant intervals along the insertion direction of the sleeve part 11a or the sleeve part 11b. The specific arrangement mode of the plurality of anti-deformation structures can be selected according to practical situations, and the application is not limited in particular.

Since the deformation-resistant structure is welded to the inner walls of the adjacent two sleeve members, the side of the deformation-resistant structure for welding needs to match the shape of the inner walls of the adjacent two sleeve members. For the sleeve member 11a and the sleeve member 11b, when the sleeve member 11a and the sleeve member 11b are each L-shaped in cross-sectional profile as shown in fig. 3, the deformation-resistant structure 13 may be a reinforcing rib of a triangular cross-section or a reinforcing rib of a rectangular cross-section. As for the specific cross-sectional profile shape of the deformation-resistant structure 13, it may be specifically selected according to the actual situation as long as it can achieve welding with the inner walls of the two sleeve members, which is not specifically limited in this application.

In order to facilitate welding the deformation-resistant structure 13 welded by any sleeve part with the inner wall of the adjacent sleeve part, and avoid extending the welding gun into the inner side of the cylindrical structure formed by the two sleeve parts, the application further provides a welding hole 14 for welding the deformation-resistant structure 13 on the sleeve part, wherein the welding hole 14 is a through hole penetrating the side wall of the sleeve part and corresponds to the deformation-resistant structure 13, so as to expose the side wall welding position of the corresponding deformation-resistant structure 13. By providing the welding holes 14, the welding between the deformation-resistant structure 13 and the inner wall of the adjacent sleeve member can be completed in a plug welding manner, and the welding from the outside is more convenient than the welding between the inner side of the cylindrical structure formed by extending into the two sleeve members 11.

In the case where the deformation preventing structure 13 is provided in plural, the number of the welding holes 14 may be equal to or smaller than the number of the deformation preventing structures 13. Specifically, in the case where the deformation preventing structures 13 are plural, the deformation preventing structures 13 may be disposed relatively intensively at a position near the middle of the sleeve member 11, so that the number of the welding holes 14 may be set to be identical to the number of the deformation preventing structures 13, and the welding of the deformation preventing structures 13 is completed through the welding holes 14. In addition, if there is a part of the deformation preventing structure 13 provided at the end of the sleeve member 11, where the upper end or the lower end is not distinguished, the deformation preventing structure 13 provided at either end may not be welded through the welding hole 14, since the end position is not limited by the difficulty of penetration of the welding gun, and thus the number of the welding holes 14 may be smaller than the number of the deformation preventing structures 13 in this case. As to how to design the number relationship between the welding holes 14 and the deformed structure 13, it may be set according to actual conditions, which is not particularly limited in the present application.

The inner shearing resistant structure 12 is arranged on the inner wall of the outer sleeve 1, so that the shearing strength of the connecting structure can be enhanced, and the outer shearing resistant structure 21 is arranged on the outer wall of the inner core column 2, so that the shearing strength of the connecting structure can be enhanced.

It should be noted that, the arrangement and materials of the outer shear structure 21 may be flexibly selected according to the specific shear strength requirement or cost requirement, which is not particularly limited in this application. For example, steel bars that are disposed at intervals along the insertion direction of the inner leg 2 and are parallel to each other may be selected as the outer shear structure 21, or iron bars that are disposed at intervals along the insertion direction of the inner leg 2 but are staggered with each other may be selected as the outer shear structure 21.

In order to further strengthen the shear strength of the connection structure, the outer shear structure 21 of the outer wall of the inner leg 2 is staggered with the inner shear structure 12 of the inner wall of the outer sleeve 1 when the inner leg 2 is inserted into the outer sleeve 1.

While preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the application.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit or scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims and the equivalents thereof, the present application is intended to cover such modifications and variations.
