A type of earthquake-resistant steel structure house connection node

Abstract

This utility model relates to a seismically resistant steel structure building connection node, including a steel structure column, with mounting holes on the side wall of the steel structure column and a horizontally arranged steel structure beam installed thereon, the steel structure column and the steel structure beam being perpendicular to each other; and a shear-resistant support assembly installed on the steel structure column. The shear-resistant support assembly is used to improve the stability between the steel structure column and the steel structure beam. Through the use of the shear-resistant support assembly and the limiting assembly, the bolts at the node can be better protected against shear. When the steel structure beam is subjected to a large downward pressure, it can prevent the bolts at the node between the steel structure column and the steel structure beam from being compressed and broken by shear force, which is beneficial to improving the protection of the bolts and thus improving the stability between the steel structure column and the steel structure beam. At the same time, it can quickly limit and fix multiple bolts, greatly improving the installation efficiency and making it convenient to use.

Description

Technical Field

[0001] This utility model relates to the field of steel structure housing technology, and in particular to a connection node for earthquake-resistant steel structure housing. Background Technology

[0002] A house is a building constructed by humans for living and storing things. It can shelter from wind and rain and provide space for living, working and storage. With the development of architecture, the types of building materials have increased, including concrete structure houses, steel structure houses, brick houses and wooden houses. A house has a fixed foundation, a roof and walls. In steel structure houses, steel structure columns and steel structure beams are needed to support the roof. The connection parts of steel structure columns and steel structure beams are called connection nodes. In order to improve the seismic performance of steel structure houses, seismic-resistant steel structure connection nodes are needed.

[0003] A search revealed Chinese patent CN212026629U, which discloses a steel structure node component for energy-saving and environmentally friendly housing construction. The steel structure column has a horizontally mounted steel beam on its side. Right-angle irons are installed at the corners connecting the steel structure column and the steel beams, and these right-angle irons are connected together by fixing bolts. A set of buffer springs is connected to the middle of the steel structure column via spring-limiting pads, and an anti-seismic connecting rod is inserted through the middle of the buffer springs. The right end of the anti-seismic connecting rod passes through the steel structure column and connects to a reinforcing connecting seat on the side of the steel beam, and is fixed with a protective nut. The buffer springs at the connection between the steel structure column and the steel beam absorb and buffer the vibration of the steel structure, reducing vibration damage to the bolts at the connection and preventing the bolts from loosening due to vibration.

[0004] This patent only provides protection against bolt loosening, but it cannot provide better shear protection for bolts at joints. When the steel structure beam is subjected to a large downward pressure, the transverse bolts at the joint between the steel structure column and the steel structure beam are prone to breakage due to shear force. This is not conducive to improving bolt protection or the stability between the steel structure column and the steel structure beam. At the same time, it cannot quickly limit and fix multiple bolts, which is not conducive to improving installation efficiency. Utility Model Content

[0005] In view of the technical problems in existing patents, which can only protect bolts from falling off but cannot provide better shear protection for bolts at joints, when the steel structure beam is subjected to a large downward pressure, the transverse bolts at the joint between the steel structure column and the steel structure beam are prone to breakage due to shear force. This is not conducive to improving bolt protection and stability between the steel structure column and the steel structure beam. At the same time, it cannot quickly limit and fix multiple bolts, which is not conducive to improving installation efficiency. Therefore, this utility model provides a seismic-resistant steel structure building connection node.

[0006] The technical solution adopted in this utility model is: a connection node for earthquake-resistant steel structure houses, comprising:

[0007] A steel structure column, wherein the side wall of the steel structure column is provided with mounting holes and is equipped with a horizontally arranged steel structure beam, and the steel structure column and the steel structure beam are perpendicular to each other.

[0008] A shear-resistant support assembly is installed on the steel structure column to improve the stability between the steel structure column and the steel structure beam. The shear-resistant support assembly includes a fixed plate, a first side plate, and a second side plate. The fixed plate is installed between the steel structure column and the steel structure beam. The first side plate is located on the side of the fixed plate away from the steel structure column. The second side plate is located inside the steel structure column. The side wall of the steel structure column and the side wall of the fixed plate are located between the first side plate and the second side plate. Both the first side plate and the second side plate have screw holes. A first bolt passes through the screw hole and is threaded into the mounting hole and the side wall of the fixed plate. The threaded end of the first bolt is inclined downward.

[0009] Furthermore, the fixing plate is equipped with a limiting component, which is used to limit the bolt.

[0010] Furthermore, the limiting component includes a slide rail, a clamping plate, and a pressing plate. The slide rail and the clamping plate are fixedly connected, and both the slide rail and the clamping plate are fixedly connected to the fixing plate. The pressing plate is slidably connected within the slide rail and the clamping plate.

[0011] Furthermore, the height of the end of the slide rail near the clamp is lower than the height of the end away from the clamp.

[0012] Furthermore, an inclined plate is fixedly installed in the middle part of the fixing plate.

[0013] Furthermore, a second bolt is provided on the fixing plate, and the second bolt is provided on the steel structure beam. The second bolt is threadedly connected to both the fixing plate and the steel structure beam.

[0014] The beneficial effects of this utility model are:

[0015] This invention, through the setting of shear-resistant support components, can achieve better shear protection for bolts at the joints. When the steel structure beam is subjected to a large downward pressure, it can prevent the bolts at the connection joint between the steel structure column and the steel structure beam from being compressed and broken by shear force, greatly improving the protection effect of the bolts at the connection joint, thereby improving the stability between the steel structure column and the steel structure beam.

[0016] Secondly, by setting up a limiting component, this utility model can achieve the effect of quickly limiting and fixing multiple bolts, preventing the bolts from slipping out due to vibration, and greatly improving the installation efficiency. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0025] To address the problems existing in the background technology, this application proposes the following technical solution: a steel structure house connection node with earthquake resistance.

[0026] The specific technical solution includes steel structure column 1 and shear-resistant support component 4;

[0027] like Figure 1-4 As shown, the steel structure column 1 has mounting holes 2 on its side wall and is fitted with a horizontally arranged steel structure beam 3. The mounting holes 2 facilitate the installation of bolts 404. The steel structure beam 3 supports the roof of the building. The steel structure column 1 and the steel structure beam 3 are perpendicular to each other. A shear support assembly 4 is installed on the steel structure column 1. The shear support assembly 4 is used to improve the stability between the steel structure column 1 and the steel structure beam 3. The shear support assembly 4 includes a fixing plate 401, a side plate 402, and a side plate 403. The fixing plate 401 facilitates the connection between the steel structure column 1 and the steel structure beam 3. The side plates 402 and 403 can be clamped on both sides of the steel structure column 1 and the fixing plate 401. The fixing plate 401 can fix the steel structure column 1 to the side wall of the fixing plate 401. Between the steel structure column 1 and the steel structure beam 3, side plate 1 402 is located on the side of the fixing plate 401 away from the steel structure column 1, and side plate 2 403 is located inside the steel structure column 1. The side wall of the steel structure column 1 and the side wall of the fixing plate 401 are located between side plate 1 402 and side plate 2 403. Both side plates 1 402 and side plate 2 403 have screw holes 5. The screw holes 5 can easily install bolt 1 404. Bolt 1 404 passes through the screw holes 5 and is inserted into the mounting hole 2 and the side wall of the fixing plate 401. Bolt 1 404 can fix the steel structure column 1, fixing plate 401, side plate 1 402 and side plate 2 403 through the mounting hole 2 and screw hole 5. Bolt 1 404 is threadedly connected to screw hole 5, and the threaded end of bolt 1 404 is inclined downward.

[0028] Both mounting holes 2 and screw holes 5 are inclined downwards. A fixing plate 401 is placed on one side of the lower mounting hole 2 on the steel structure column 1, with the horizontal surface of the fixing plate 401 facing upwards and its sidewall facing the steel structure column 1. Side plate 402 is placed inside the fixing plate 401, and then bolt 404 is screwed into the screw hole 5 on side plate 402. Bolt 404 is then tightened, causing it to enter the sidewall of the fixing plate 401 and then into mounting hole 2. Side plate 403 is then placed inside the steel structure column 1, and bolt 404 is tightened again to... Bolt 404, protruding from mounting hole 2 on steel structure column 1, is screwed into screw hole 5 on side plate 403. At this time, side plate 402 and side plate 403 are clamped on both sides of steel structure column 1 and fixing plate 401. Bolt 404 is first fixed to side plate 402 through screw hole 5, then inserted into the side wall of fixing plate 401 and fixed to fixing plate 401, then inserted into mounting hole 2 on side wall of steel structure column 1 and fixed to steel structure column 1, and finally fixed to side plate 403 through screw hole 5. 04 can vertically fix the steel structure column 1, fixing plate 401, side plate one 402, and side plate two 403. Tightening bolt one 404 can cause side plate one 402 and side plate two 403 to press against the steel structure column 1 and fixing plate 401 through the screw holes 5 on both sides, thus fixing the fixing plate 401 to the steel structure column 1. By placing another fixing plate 401 on one side of the steel structure column 1 and on one side of the mounting hole 2 at the upper end of the steel structure column 1, with the side wall of the upper fixing plate 401 facing the steel structure column 1 and the horizontal plane facing downward, according to the above... The steps involve fixing two fixing plates 401 to the steel structure column 1, placing one end of the steel structure beam 3 against the side wall of the steel structure column 1, with the steel structure column 1 placed vertically and the steel structure beam 3 placed horizontally, the steel structure beam 3 passing between the two fixing plates 401. When the steel structure beam 3 applies pressure to the fixing plate 401 below, the fixing plate 401 applies pressure to the bolt 404. Since the threaded end of the bolt 404 is set downward, the force on the bolt 404 can be decomposed into a downward pressure, which can reduce the shear force on the bolt 404.

[0029] like Figure 1 and Figure 4As shown, a limiting component 6 is installed on the fixing plate 401. The limiting component 6 is used to limit the bolt 404. The limiting component 6 includes a slide rail 601, a clamping plate 602 and a pressing plate 603. The slide rail 601 can limit the pressing plate 603, and the clamping plate 602 can clamp and limit the side wall of the pressing plate 603. The pressing plate 603 can abut against the upper hexagonal end of the bolt 404. The slide rail 601 and the clamping plate 602 are fixedly connected. The slide rail 601 and the clamping plate 602 are both fixedly connected to the fixing plate 401. The pressing plate 603 is slidably connected in the slide rail 601 and the clamping plate 602. The height of the end of the slide rail 601 near the clamping plate 602 is lower than the height of the end away from the clamping plate 602.

[0030] After bolt 404 is installed, the pressing plate 603 is inserted into the slide rail 601 and the clamping plate 602. Since the end of the slide rail 601 away from the clamping plate 602 is higher than the end near the clamping plate 602, the pressing plate 603 slides downward at an angle when it is inserted into the slide rail 601. The end of the pressing plate 603 that is near the clamping plate 602 in the structure inside the slide rail 601 is lower than the end that is away from the clamping plate 602, which can prevent the pressing plate 603 from falling out of the slide rail 601. After the pressing plate 603 is fixed, it can fix the upper hexagonal end of bolt 404, which can prevent bolt 404 from sliding out of the mounting hole 2 and the screw hole 5.

[0031] like Figure 1 and Figure 3 As shown, a ramp 7 is fixedly installed in the middle part of the fixed plate 401. The triangular structure of the ramp 7 can provide tilt support for the fixed plate 401, thereby improving the stability of the fixed plate 401.

[0032] like Figure 1 As shown, a bolt 28 is inserted through the fixing plate 401. The bolt 28 is inserted into the fixing plate 401 and then into the steel structure beam 3. The bolt 28 is fixed to the fixing plate 401 and then to the steel structure beam 3, which can drive the fixing plate 401 and the steel structure beam 3 to be fixed together. The bolt 28 is inserted on the steel structure beam 3, and the bolt 28 is threadedly connected to both the fixing plate 401 and the steel structure beam 3.
