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:
the outer sleeve 1 and the inner leg 2 are respectively positioned on different parts, the inner leg 2 is inserted into the outer sleeve 1 to form a connecting cavity, and the connecting cavity is used for filling connecting materials so as to connect the different parts; and
the inner shear structure 3 comprises a plurality of mounting rods 31 which are arranged at intervals and shear ribs 32 which are connected to the same side ends of the mounting rods;
the lateral wall of outer sleeve 1 has offered a plurality of mounting holes 11 that link up, and mounting rod 31 wears to locate mounting hole 11 so that shearing rib 32 sets up in the inside of outer sleeve 1.
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. For improving connection structure's shear strength, this application embodiment further adopts "through opening the fixed rib that shears of through-hole cooperation installation pole" this conception, need not to use welding process again with the rib that shears at the outer sleeve inner wall, avoids the structure welding deformation problem that leads to the fact because of the welding brings structural stress to solve simultaneously because of the outer sleeve opening is relatively narrow and small, the welder is difficult to stretch into and the inner wall welding efficiency who brings is low and the problem that welding qualification rate is low. Compared with the welding of the shearing rib on the inner wall, the method has the advantages of maintaining the structural shape and improving the manufacturing efficiency, and the method is simple in tapping process, and can flexibly adjust the tapping position according to actual requirements to change the setting position of the stiffening rib, so that the welding process cannot be realized, and the method has obvious advantages in structural flexibility.
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 can be particularly positioned in the wall body at the corresponding positions of adjacent floors and used for connection, and the requirements of connection between the upper layer steel columns and the lower layer steel columns exist, so that the steel columns can be connected through the connection structure of the proposal. 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 in whole or in part.
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.
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 connection structure's shear strength, this application has further set up interior shear structure 3 on outer sleeve 1, through interior shear structure 3 and filling material matched with, can promote connection structure's shear strength.
To avoid welding work in the barrel of the outer sleeve 1, the inner shear structure 3 illustratively comprises a plurality of mounting bars 31 arranged at intervals and shear ribs 32 connected to the same side ends of the plurality of mounting bars. Meanwhile, in order to match the structure of the inner shearing structure 3, a plurality of through mounting holes 11 are formed in the side wall of the outer sleeve 1, and the mounting rod 31 is arranged in the mounting holes 11 in a penetrating manner so that the shearing rib 32 is arranged inside the outer sleeve 1. The welding process is replaced by the connection achieved through the matching of the mounting holes 11 and the mounting rods 31, and the problem that welding gun is difficult to extend into due to the fact that the inside of the outer sleeve is narrow can be solved.
The spacing width, number and length of the shear ribs 32 provided by the mounting bars 31 may be specifically set according to the width of the outer sleeve side or the shear strength required for the connection structure. For example, when the width of the outer sleeve side is wider or the required shear strength of the connection structure is higher, relatively more mounting bars 31 and longer shear ribs 32 are required; conversely, relatively few mounting bars 31 and shorter shear ribs 32 are required. As to how to select the interval width, the number of the mounting bars 31 and the length of the shear ribs 32 when the present application is carried out, this is not particularly limited in the present application.
The shear rib 32 may be formed of one strip or a plurality of strips, for example. For example, when the shear rib 32 is linear, a strip may be optionally used as the shear rib 32. When the shear rib 32 is in a non-linear shape such as a zigzag, wavy, V-shaped, etc., a plurality of strips may be optionally bonded or welded to form the shear rib. Likewise, the strip itself may be linear, zigzag, wavy, V-shaped, or the like. The specific shape of the shear rib 32 may be determined according to practical application requirements, which is not particularly limited in this application. When the shear rib 32 is composed of a plurality of strips, at least one strip is connected to one side end of the mounting bar 31. That is, only one bar may be connected to one side end portion of all the mounting bars 31, or a plurality of bars may be connected to one side end portion of different mounting bars 31, respectively.
In carrying out the present application, the cross-sectional profile of the mounting bar 31 may be circular, quadrangular, pentagonal, etc., as long as it can be fitted with the mounting hole 11; meanwhile, the cross-sectional profile of the shear rib 32 may be circular, quadrangular, pentagonal, etc., as long as it can be connected with the mounting bar 31. There are various ways of implementing the connection between the mounting bar 31 and the shear rib 32, for example, welding connection, or adhesive connection, etc., which are not particularly limited in this application.
In the present embodiment, at least one mounting rod 31 is provided with threads at one end to which the shear rib 32 is not attached, and the mounting rod 31 passes through the mounting hole 11 and is coupled with a nut.
For example, to further enhance the connection strength between the inner shear structure 3 and the outer sleeve 1, an adhesive material may be coated on the outer wall of the outer sleeve 1 after the mounting rod 31 is inserted into the mounting hole 11, so that the mounting rod 31 is adhered to the mounting hole 11; alternatively, to facilitate the assembly and disassembly of the inner shear structure 3 from the outer sleeve 1, a screw thread may be provided at the end of the mounting rod 31 extending beyond the outer sleeve 1 for connection with a nut. In this way, the inner shear structure 3 can be firmly fixed on the outer sleeve 1 by the nut.
When the outer sleeve 1 is longer along the length of the sleeve in the direction of the inner leg 2, the inner shear structures 3 may be arranged at intervals along the insertion direction of the inner leg 2, so as to enhance the shear strength of the connection structure. However, how many inner shear structures 3 are specifically disposed and how to dispose the spacing distance between the inner shear structures 3 can be determined according to the shear strength requirement in the actual environment, which is not specifically limited in this application.
The inner shearing resistant structure 3 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 4 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 manner and the material of the outer shear structure 4 may be flexibly selected according to the specific shear strength requirement or the cost requirement, which is not specifically 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 4, 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 4.
In order to further strengthen the shear strength of the connection structure, the outer shear structure 4 of the outer wall of the inner leg 2 is staggered with the inner shear structure 3 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.
