Description

Technical Field

[0001] The invention relates to the technical field of steel structure connection, and in particular to an assembled steel structure node and an assembled steel structure column. Background Art

[0002] Steel structure is a natural prefabricated structure. At present, the column connection nodes of prefabricated steel structure are mainly welded or bolted. The node area is about 500mm-1200mm. If the system of bolts and node plates is used, the column node area will be large, the appearance will be unsightly, and it will affect the later decoration. If welding is used, the welds on site are prone to corrosion, which will affect the strength of the steel structure. In summary, whether it is welding or bolting, the construction efficiency is low and the construction cost is high. Summary of the invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the steel structure connection structure in the prior art, such as low construction efficiency and structural strength, and inconvenience for later decoration, thereby providing an assembled steel structure node and assembled steel structure column with high construction efficiency and structural strength, and convenient for later decoration.

[0004] In order to solve the above technical problems, the present invention provides a prefabricated steel structure node, comprising:

[0005] A first mounting member and a second mounting member spliced ​​to each other, wherein the first mounting member and the second mounting member are spliced ​​along the assembly direction of the steel structure column, and the first mounting member and the second mounting member are used to be fixedly mounted on two steel structure columns to be assembled respectively;

[0006] The first connecting member and the second connecting member are respectively arranged at predetermined positions of the first mounting member and the second mounting member, and are plugged and fixed along the assembly direction of the steel structure column through the first plug-in portion and the second plug-in portion.

[0007] In the fabricated steel structure node, the predetermined position is a groove body provided on the outer side walls of the first mounting member and the second mounting member, and the first connecting member and the second connecting member are embedded in the groove body.

[0008] The fabricated steel structure node, the first connecting member includes at least one first conical portion and a first plug-in portion connected to the first conical portion, the second connecting member includes at least one second conical portion and a second plug-in portion formed on the second conical portion, and the large ends of the first conical portion and the second conical portion are arranged close to each other.

[0009] In the fabricated steel structure node, the first plug-in portion is a tenon, and the second plug-in portion is a mortise.

[0010] In the fabricated steel structure node, the trough is circumferentially opened on the outer side walls of the first mounting member and the second mounting member.

[0011] In the fabricated steel structure node, the shape of the trough body is consistent with the shapes of the corresponding first connecting member and the second connecting member.

[0012] The fabricated steel structure node further includes a first fastener penetrating the first connecting member and fixed in the first mounting member, and a second fastener penetrating the second connecting member and fixed in the second mounting member.

[0013] In the fabricated steel structure node, the first fastener and the second fastener are both bolts.

[0014] The present invention also provides a prefabricated steel structure column, comprising the prefabricated steel structure node.

[0015] The technical solution of the present invention has the following advantages:

[0016] 1. The assembled steel structure node provided by the present invention realizes connection and fixation by means of the first mounting member and the second mounting member fixedly mounted on the two steel structure columns to be assembled through the plug-in cooperation of the first plug-in part of the first connecting member and the second plug-in part of the second connecting member arranged thereon, and has high assembly efficiency and reduces the probability of corrosion. At the same time, the surface is flat, which is conducive to later decoration.

[0017] 2. In the assembled steel structure node provided by the present invention, the first connecting member and the second connecting member are embedded in the groove body of the outer side wall of the first mounting member and the second mounting member. In this way, the first connecting member and the second connecting member are not exposed, ensuring the flatness of the surface; and facilitating the installation and removal of the first connecting member and the second connecting member.

[0018] 3. In the assembled steel structure node provided by the present invention, the arrangement of the first conical portion and the second conical portion makes the forces of the first connecting member and the second connecting member consistent with the forces of the steel structure column itself, thereby ensuring the supporting strength of the steel structure column. At the same time, the unstressed portion is arranged as a mortise and tenon joint structure, thereby saving materials and reducing costs.

[0019] 4. The provision of the first fastener and the second fastener on the first connecting member and the second connecting member of the assembled steel structure node provided by the present invention can effectively reduce the loosening of the first connecting member and the second connecting member due to long-term use, thereby ensuring the reliability of the entire structure.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1 and 2A specific implementation of the assembled steel structure node shown in the figure includes a first mounting member 1 and a second mounting member 2 spliced ​​to each other, and a first connecting member 3 and a second connecting member 4 for connecting the first mounting member 1 and the second mounting member 2. The first mounting member 1, the second mounting member 2, the first connecting member 3 and the second connecting member 4 are all steel structural members, and are prefabricated members. After being transported to the construction site, they only need to be spliced ​​and installed. The first mounting member 1 and the second mounting member 2 are spliced ​​along the assembly direction of the steel structure column 5, generally vertically or horizontally, and the first mounting member 1 and the second mounting member 2 are used to be fixedly installed with two steel structure columns 5 to be assembled, respectively, and the connection and fixation of the mounting members and the steel structure columns 5 can be achieved by welding. The first connecting member 3 and the second connecting member 4 are respectively embedded in the groove body 6 of the outer side wall of the first mounting member 1 and the second mounting member 2, and are plugged and fixed along the assembly direction of the steel structure column 5 through the first plug-in portion 8 and the second plug-in portion 10, so as to connect and fix the two steel structure columns 5 to be assembled.

[0030] In order to make the force of the connecting piece consistent with the force of the steel structure column 5 and save raw materials at the same time, the first connecting piece 3 includes two first conical parts 7 and a first plug-in part 8 connected to the first conical part 7 located below, the two first conical parts 7 are connected by a connecting rod to form a fishbone structure, and the small end faces upward; the second connecting piece 4 includes two second conical parts 9 and a second plug-in part 10 formed on the second conical part 9 located above, the two second conical parts 9 are connected by a connecting rod to form a fishbone structure, and the small end faces downward, the large ends of the first conical part 7 and the second conical part 9 are arranged close to each other, and are arranged with the first plug-in part 8 as the axis of symmetry.

[0031] Specifically, the first plug-in portion 8 is a tenon, and the second plug-in portion 10 is a mortise. Of course, the first plug-in portion 8 can also be a mortise, and correspondingly, the second plug-in portion 10 is a tenon. The tenon-mortise and tenon matching method is simple, and has certain structural strength and supporting stability. The first plug-in portion 8 can also be a protrusion, and the second plug-in portion 10 is a groove, or the first plug-in portion 8 is a groove, and the second plug-in portion 10 is a protrusion.

[0032] In order to further improve the strength and stability of the connection, the groove body 6 is circumferentially opened on the outer side walls of the first mounting member 1 and the second mounting member 2. Two groove bodies 6 are arranged on each outer side wall, and the shape of the groove body 6 is consistent with the shape of the corresponding first connecting member 3 and the second connecting member 4.

[0033] In order to prevent the first connecting member 3 and the second connecting member 4 from falling off after long-term use, a first fastener 11 is also provided through the first connecting member 3, and one end of the first fastener 11 is fixed in the first mounting member 1; similarly, a second fastener 12 is provided through the second connecting member 4, and one end of the second fastener 12 is fixed in the second mounting member 2. Specifically, both the first fastener 11 and the second fastener 12 are bolts. Two bolt holes are formed in parallel at the corresponding positions of the first mounting member 1 and the second mounting member 2, and the bolts are passed through the bolt holes to achieve fixation.

[0034] As an alternative embodiment, the first connecting member 3 and the second connecting member 4 can also be respectively fixed on the two end surfaces where the first mounting member 1 and the second mounting member 2 are spliced ​​with each other, and embedded inside the mounting members. When the first mounting member 1 and the second mounting member 2 are spliced ​​together, the first connecting member 3 and the second connecting member 4 are completely hidden inside and not exposed.

[0035] An assembled steel structure column, such as Figure 3 and 4 As shown, it includes the assembled steel structure node, and the first mounting member 1 and the second mounting member 2 are fixed to two steel structure columns 5 to be assembled by welding.

[0036] The use of prefabricated rigid structure nodes can reduce the node area to 300mm while keeping the size of the steel structure building node unchanged, which has a higher degree of industrialization and reduces the difficulty of installation. The outer surface is flat and beautiful, and does not affect the subsequent decoration. Through the effective connection of the connectors, the prefabricated rigid structure nodes can transmit forces in all directions. At the same time, it has good economic benefits and market competitiveness.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
