Detailed Description

The present application is described in further detail below with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant content and not limiting of the application. It should be further noted that, for convenience of description, only the portions relevant to the present application are shown in the drawings.

In addition, embodiments and features of embodiments in the present application may be combined with each other without conflict. The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in combination with embodiments.

Unless otherwise indicated, the exemplary implementations/embodiments shown are to be understood as providing exemplary features of various details of some of the ways in which the technical concepts of the present application may be practiced. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present application.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present application may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., as in "sidewall"), etc., to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when the terms "comprises" and/or "comprising," and variations thereof, are used in the present specification, the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof is described, but the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof is not precluded. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximation terms and not as degree terms, and as such, are used to explain the inherent deviations of measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

After the center reinforced type space steel structure is assembled, the steel bars can be inserted into the sleeve, the shear resistant member is convenient to install, the shear resistant member penetrates through the whole inner space, the strength of concrete is improved, and therefore the strength of the whole center reinforced type space steel structure is also improved.

Through the welding among the components and the fixing effect of the shearing resistant part and the concrete, the stability of the central reinforced space steel structure node is enhanced, the rapid assembly on the construction site can be realized, and most time and energy are not required; has the advantages of reasonable and stable structure, simple operation, high efficiency and practicability.

Compared with the prior art, the beneficial effects of the application are as follows:

1. the central reinforced type space steel structure mainly comprises main beam and secondary beam nodes, wherein the traditional beam through type node is mainly subjected to shearing deformation of a beam web of a core area along the diagonal direction in a failure mode under reciprocating loading, and the core area of the node is always the weakest part of the structure. The utility model relates to the technical field of joint connection of central reinforced spatial steel structures, and solves the problem of low strength of the central reinforced spatial steel structure.

2. After the grouting treatment, the bending resistance and the shearing resistance of the joint point can be greatly improved with the help of grouting materials. Because there are four independent parts in this node, through the through-hole of web (first connecting plate, second connecting plate and third connecting plate) realized the circulation between four cavities (accommodation space), only need carry out the grout in one of them part during the grout, can realize the packing of whole node. The joint strength of the concrete and the central reinforced space steel structure can be improved due to the existence of the through long bolts and the shearing resistant pieces. And compare convenient and fast more in traditional grout mode, the construction of being convenient for.

3. The shear member is more convenient to install, better in contact with concrete, better in reliability and connection performance between the shear member and the web plate and the steel plate, and capable of enhancing the bearing capacity and the shock resistance of the concrete, so that the comprehensive strength of the node is improved.
