Description

Technical Field

[0001] The utility model belongs to the technical field of building structures, and in particular relates to a square steel tube concrete beam-column component based on a double T-plate type node form. Background Art

[0002] In the current construction industry, the requirements for the degree of assembly of projects are getting higher and higher; and the proportion of composite structures in existing building forms is gradually increasing due to their high degree of assembly, simple construction, and durability. The beam-column node form of composite structures has also gradually developed, and more and more beam-column node forms are applied in actual projects. At present, beam-column nodes are mainly connected by welding, relying on welds to transmit the force between beams and columns, which will produce a series of defects such as high welding quality requirements, complex construction, welding quality is greatly affected by human factors, large residual stress in welds and around welds, and seismic performance is greatly affected by welds. If the beam does not penetrate the column, the size of the reinforcement ring for auxiliary node force transmission is large; if the beam penetrates the column, the root of the column needs to be welded to the beam, and the seismic performance of the node is poor. In view of this, Chinese patent announcements such as "CN215253823U" and "CN112832371B" have utilized traditional mortise and tenon technology, and adopted node mortise and tenon assembly to achieve the connection effect at the nodes of beam-column components; however, considering the structural strength, this type of structure still has problems of complex construction and high cost, resulting in poor actual application effects; therefore, it is urgent to solve this problem. Summary of the invention

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a square steel tube concrete beam-column component based on a double T-plate type node form, which has the advantages of compact and reasonable structure and convenient and quick construction, good stress in the core area of ​​the node, and labor costs and time costs can also be effectively reduced.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The square steel tube concrete beam-column component based on the double T-plate type node form is characterized by: comprising a cross connector that is in the shape of a "well" in a top view, and an upper column and a lower column that are coaxially arranged with the axis of the cross connector; slots are arranged at the adjacent ends of the upper column and the lower column, and the two columns can move toward each other and use the slots to insert the top and bottom of the cross connector respectively until the adjacent ends are adjacent to or fit each other; the part of the cross connector that extends out of the column sides of the upper column and the lower column constitutes a socket for the horizontal beam to be inserted laterally.

[0006] Preferably, node plates are arranged at the top and bottom of the wellhead of the "well"-shaped cross connector, and the shape of the node plate is consistent with the shape of the inner cavity cross-section of the upper column and the lower column, so that the corresponding column can be inserted into the cross connector through the slot after being inserted into the node plate; a pouring hole for concrete pouring connected to the inside of the wellhead is opened at the node plate, and an arc opening is recessed at the edge of the node plate, which encloses the inner cavity wall of the upper column or the lower column to form a release hole for gas to pass through.

[0007] Preferably, the arc openings are opened at four corner ends of the square plate-shaped node plate.

[0008] Preferably, the injection hole and the axis of the cross connector are coaxial with each other.

[0009] Preferably, the "well"-shaped cross connector includes a transverse plate group consisting of two first vertical plates parallel to each other and a longitudinal plate group consisting of two second vertical plates parallel to each other. The adjacent ends of the transverse plate group and the longitudinal plate group are provided with card grooves so that the two plate groups with perpendicular plate surfaces can move toward each other and be plugged into each other to form a "well"-shaped structure.

[0010] Preferably, the bottom of the slot is located at 1 / 2 of the height of the corresponding vertical plate.

[0011] Preferably, four beam bottom plates are arranged at the bottom of the cross connector, and the beam bottom plates cooperate with the node plates located at the bottom of the wellhead to form a cross plate-shaped structure that closes the bottom of the cross connector.

[0012] Preferably, the upper column and the lower column are both in the shape of square tubes, and two slots parallel to each other are provided on each surface of each column, with a total of eight slots on each column, so as to be respectively inserted into the corresponding vertical plates of the cross connector.

[0013] Preferably, there are four horizontal beams, all of which are in the shape of square tubes. The end faces of the four horizontal beams are fitted to the side walls of each column and then welded to each other.

[0014] Preferably, the horizontal beam body is provided with through holes communicating with the tube cavity, and the through holes are arranged in sequence along the length direction of the horizontal beam body.

[0015] The beneficial effects of the utility model are:

[0016] 1) Through the above scheme, the utility model uses a "well"-shaped cross connector to provide an installation carrier for the upper column, the lower column and the horizontal beam, and uses the mortise and tenon plug-in function of the upper column and the lower column relative to the cross connector to achieve the purpose of simplification, practicality and convenient operation of its structure; at the same time, the four ends of the cross connector extend out of the side walls of each column to form a socket for the horizontal beam to be inserted laterally, so as to further use the plug-in effect to ensure assembly efficiency. Finally, the connection gaps and other areas of each can be tightened later by welding and other methods, which has extremely high construction efficiency, further saves construction time and construction costs, and the force effect of the core area of ​​the node can also be effectively guaranteed.

[0017] 2) As a further preferred solution of the above solution: the node plate is not only used to position the upper and lower columns, but also to effectively tie the columns together to prevent the buckling of the column wall on the side of the square steel tube concrete column, thereby further ensuring the force effect of the node core area. In addition, the pouring holes and arcs arranged at the node plate facilitate the pouring of concrete, achieving multiple goals at one stroke and with significant results.

[0018] 3) Furthermore, the vertical plates, which are the main components of the cross connector, can not only be quickly assembled on site by plugging and matching each other, but also rely on the beam bottom gusset plate to ensure the fastening effect of the cross connector and ensure the structural stability of the cross connector during construction. Of course, if necessary, a gusset plate can also be arranged on the top of the cross connector, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, a horizontal beam 30 is arranged at the front, rear, left and right respectively. After the four horizontal beams 30 are connected in pairs, they are combined to form a square steel tube concrete composite beam in two directions; a through hole 31 connecting the tube cavity is opened on the horizontal beam 30 to improve the overall strength of the composite beam during the later pouring. Figure 5 The structure shown in the figure is composed of four vertical plates, two node plates 40 and four beam bottom plates 50 to form an integral part. Figure 1 The connection structure shown is suitable for rapid connection and forming of steel tube concrete beam-column nodes.

[0032] Further, see Figure 5 The cross connector 10 shown is the core. Figure 2-Figure 3 As shown, it includes a transverse plate group consisting of two mutually parallel first vertical plates 11 and a longitudinal plate group consisting of two mutually parallel second vertical plates 12. Each vertical plate is provided with a 1 / 2 height slot 13 for splicing each other, and welding reinforcement can be considered later. Figure 5 In the cross connector 10, two parallel vertical plates are connected to each other through the beam bottom plate 50 to form a C-shaped connection; at the same time, the top and bottom of the wellhead area of ​​the cross connector 10 are covered and fixed with a node plate 40. A circular hole 41 is provided in the middle of the node plate 40 for concrete pouring; the four corners of the node plate 40 are provided with a quarter-circular hole-shaped arc 42 for passing gas during the above concrete pouring; of course, the arc 42 can also be used for pouring.

[0033] Reference Figure 2-Figure 3 It can be seen that the square steel tube concrete column 20 is broken at the center of the composite beam height to form an upper column 21 and a lower column 22; slots 23 are provided at the adjacent ends of the two columns to facilitate Figure 4 The plug-in structure is formed as shown. Figure 4 After the forming is completed, the four ends of the cross connector 10 extend out of the column side and are connected to the square steel tube concrete composite beam, finally forming Figure 1 Combination status shown.

[0034] So far, the technical advantages of the utility model include:

[0035] 1. Construction and installation are quick and convenient.

[0036] The beams and columns are connected by a C-shaped connecting portion extending out of the column side, and the internal vertical plates are connected by a slot 13, which is simple and practical, and can effectively improve the construction efficiency, save construction time and construction cost.

[0037] 2. The core area of ​​the node is well stressed.

[0038] The vertical plates in two directions are connected through the wellhead to form a "well"-shaped structure; at the same time, node plates 40 are arranged at the top and bottom of the cross connector 10, so as to further enhance the mechanical properties of the node core area on the basis of facilitating concrete pouring, and more effectively prevent the square steel tube concrete composite beam from causing the column wall buckling phenomenon on the side of the square steel tube concrete column.
