Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a steel structure H-shaped steel column beam-column connection node device. Background Art

[0002] Steel structures are widely used in the construction industry, and H-shaped steel structures refer to steel structures with an "H"-shaped cross-section. Therefore, this type of steel structure has high strength, flexibility, high stability, and increases the effective use area, which can effectively increase the construction speed. When installing and using H-shaped steel columns and beams, it is usually necessary to use a connection node device to connect and fix them.

[0003] At present, the patent with publication number CN107489197A discloses a prefabricated steel structure H-shaped steel column beam-column node connection device with diagonal braces, which includes column A, beam and diagonal brace C. The column A includes an H-shaped steel column 1, a support plate 2 and a reinforced rib Ⅰ3. The length of the H-shaped steel 1 is equal to the floor height, and the support plate 2 is welded at both ends of the middle flange of the H-shaped steel column 1, and the support plate 2 is ensured to be horizontal. The reinforced rib Ⅰ3 is welded between the flange and the web of the H-shaped steel column 1, and the height of the reinforced rib Ⅰ3 is equal to the distance between the upper flange and the lower flange of the support plate H-shaped steel beam 4. The beam B includes an H-shaped steel beam 4, an end plate 5 and four reinforced ribs Ⅱ6. The end plate 5 is vertically welded to one end of the H-shaped steel beam 4 close to the column A, and the outer surface of the end plate 5 is ensured to be in the same plane as the beam end plane. The reinforced rib Ⅱ6 is welded at the intersection of the H-shaped steel beam 4 and the diagonal brace 7 to prevent the local buckling of the reinforced rib Ⅱ6. The beam-column node is a rigid node connected by on-site bolts. At the same time, the setting of the diagonal brace can significantly improve the stiffness and bearing capacity of the node, reduce the amount of bolts, and effectively realize the outward movement of the plastic hinge, so that the location of node failure is located on the beam outside the diagonal brace, which plays a role in protecting the node and meets the design requirements of "strong node, weak component".

[0004] However, the following problems still exist during the use of the current node connection device:

[0005] The above-mentioned device is directly installed on the steel structure by screws when in use, and the steel structure has too few connection points, that is, it is installed only by two upper and lower screws. In actual use, the two screws at the lower end become loose, which will make it difficult to achieve the purpose of connecting the steel structure. All forces are directly applied to the diagonal brace, and the side of the steel structure at the connection is thin. As the use time increases, the side of the steel structure connection is easily deformed due to the pulling of the screws, which affects the service life of the steel structure. Utility Model Content

[0008] Furthermore, two first fixing plates are symmetrically arranged about the center of the second fixing plate, and both the first fixing plate and the second fixing plate are arranged as square plate structures made of steel. Through the above structure, the side of the steel structure can be connected and fixed under the action of the first fixing plate and the second fixing plate.

[0009] Furthermore, the guide assembly also includes a receiving rail plate, a first slider and a second slider, and the receiving rail plate and the steel structure are in contact with each other, the first slider is slidably connected to the receiving rail plate through a slide groove opened at the upper end of the receiving rail plate, and the second slider is slidably connected to the receiving rail plate through a slide groove opened at the lower end of the receiving rail plate. Through the above structure, it is convenient to limit the moving range of the first slider and the second slider under the action of the receiving rail plate.

[0010] Furthermore, the first slider and the second slider are both configured as "T"-shaped plate structures, and the outer surfaces of the first slider and the second slider are both configured to be smooth, and the first slider and the second slider are both connected to each other with the second mounting screws through threaded limiting holes opened on their sides. Through the above structure, the friction between the first slider and the second slider and the receiving rail plate can be effectively reduced.

[0011] Furthermore, the positioning assembly includes an upper supporting plate and a lower supporting plate, and the first slider is fixedly connected to the upper supporting plate, and the lower supporting plate is fixedly connected to the second slider, and the upper supporting plate and the lower supporting plate are both in contact with the steel structure.

[0012] Furthermore, the positioning assembly also includes a fastening screw, and the fastening screw is arranged through the upper supporting plate, and the upper supporting plate is connected to the lower supporting plate through a threaded connection hole opened on the lower supporting plate. Through the above structure, it is convenient to ensure the clamping effect of the supporting plate and the lower supporting plate on the steel structure under the action of the fastening screw, and achieve the purpose of installing and fixing the steel structure.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The H-shaped steel column beam-column connection node device of the steel structure can support the connection of the steel structure by adding a receiving rail plate, an upper receiving plate and a lower receiving plate, thereby avoiding the side deformation of the steel structure caused by the pulling of the screws, and can achieve a stable installation of the node between the two steel structures through the first fixing plate and the second fixing plate, and can achieve the purpose of re-limiting the two steel structures under the action of the upper receiving plate, the lower receiving plate and the fastening screws, thereby increasing the stability of the connection between the two steel structures, and can effectively share the connection force by installing and fixing with multiple screws, thereby avoiding the breakage and deformation of the screws caused by excessive force at the connection.

[0023] When two steel structures in vertical distribution need to be connected (H-shaped steel column beam column connection), the horizontal steel structure is placed between the upper receiving plate 601 and the lower receiving plate 602, and then the fastening screws 603 are passed through the upper receiving plate 601 and the horizontal steel structure. At this time, the upper receiving plate 601 passes through the limiting groove opened on the left side of the horizontal steel structure, and then the fastening screws 603 are rotated. At this time, the fastening screws 603 begin to connect with the threaded connection holes opened on the lower receiving plate 602. Therefore, as the fastening screws 603 are rotated, the upper receiving plate 601 and the lower receiving plate 602 begin to connect. The upper and lower receiving plates 601 and 602 start to move in the direction of approaching each other until they are tightly fitted with the "H"-shaped grooves on the horizontal steel structure. During this process, as the upper and lower receiving plates 601 and 602 move, the first slider 502 installed on the side of the upper receiving plate 601 and the second slider 503 installed on the side of the lower receiving plate 602 start to slide in the slide grooves provided on the receiving rail plate 501. At this time, the receiving rail plate 501 and the horizontal steel structure can be installed and fixed, and then the receiving rail plate 501 is placed in the "H"-shaped groove on the vertical steel structure.
