Description

Technical Field

[0001] The utility model relates to the technical field of architectural design, and particularly relates to a concealed steel structure connection node. Background Technique

[0002] The connection node between the beam and the column in a building is a key component to ensure that the beam and the column form an integral building. During the installation process of many high-rise steel structure frames, as a connecting piece, the steel structure connection node is generally installed simultaneously with the beam or the column.

[0003] Currently, when installing and connecting steel structures, a large number of bolts are required for fixation. Since the bolts are exposed after installation, when encountering rainy weather, rainwater is likely to directly erode the bolts, causing the bolts to rust, thereby affecting the structural stability. Based on this, we propose an improvement on a concealed steel structure connection node. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a concealed steel structure connection node, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A concealed steel structure connection node includes a connecting column, a connecting steel, an angle steel, and two protective plates. A plurality of reinforcing plates are welded on the connecting column, and a partition plate is welded on the connecting steel. An installation column is fixedly connected to each of the two protective plates, and an installation rod is rotatably sleeved thereon. An installation groove is formed in the installation column, and the installation rod is movably sleeved in the installation groove. A through hole is formed in the angle steel, and the installation column is slidably sleeved through the through hole.

[0007] As a further solution of the utility model, an installation part is movably sleeved on the outer end of the connecting column, and the angle steel is welded to the installation part.

[0008] As a further solution of the utility model, a plurality of first threaded holes are formed in the connecting column and the installation part, and the installation part is fixedly connected to the connecting column by bolts threadedly sleeved in the plurality of first threaded holes.

[0009] As a further solution of the utility model, a plurality of second threaded holes are formed in the bottom plate of the angle steel and the connecting steel, and the angle steel is fixedly connected to the connecting steel by bolts threadedly sleeved in the plurality of second threaded holes.

[0010] As a further solution of the utility model, clamping plates are fixedly connected to the opposite sides of the two protective plates, and a plurality of notches are formed in the clamping plates.

[0011] As a further solution of the present utility model, the widths of multiple said notches are all greater than the diameter of the nut, the clamping plate is made of a triangular structure, and the clamping plate is arranged to match the inner side of the angle steel.

[0012] As a further solution of the present utility model, one end of the mounting rod penetrates through the protection plate and is provided with a slotted head, and the protruding part of the mounting rod is parallel to the opening direction of the slotted head.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By setting the protection plate, mounting posts and mounting rod structures, after the angle steel is installed, the protection plate is pressed at the front and rear ends of the angle steel to conceal and protect multiple bolts for installation, preventing the bolts from being corroded and rusted. When installing, the mounting rod is sleeved with the mounting post and the mounting post is rotated by a certain angle, then the two protection plates can be tightened on the outer wall of the angle steel to prevent loosening. One end of the mounting post is provided with a slotted head, and the position of the protruding part of the mounting post is distinguished along the notch direction. In the later stage, a screwdriver can be used to rotate the mounting post so that its protruding part matches the recessed part of the mounting groove, and then the two protection plates can be disassembled;

[0015] By fixedly arranging clamping plates on the inner walls of the two protection plates, it can assist in guiding during the installation of the protection plates, and at the same time strengthen the structural strength of the angle steel, which has practicality.

Specific implementation manner

[0023] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0024] As Figure 1-6 shown, a concealed steel structure connection node includes a connecting column 1, a connecting steel 2, an angle steel 3 and two protection plates 10. A plurality of reinforcing plates 6 are welded on the connecting column 1, a partition plate 7 is welded on the connecting steel 2, a mounting column 13 is fixedly connected to each of the two protection plates 10, and a mounting rod 14 is rotatably sleeved thereon. An installation groove 15 is formed in the installation column 13, the installation rod 14 is movably sleeved in the installation groove 15, a through hole 4 is formed in the angle steel 3, and the installation column 13 is slidably sleeved through the through hole 4.

[0025] In this embodiment, a mounting piece 5 is movably sleeved on the outer end of the connecting column 1, the angle steel 3 is welded to the mounting piece 5, and the outer wall of the reinforcing plate 6 is attached to the inner wall of the mounting piece 5.

[0026] In this embodiment, a plurality of first threaded holes 8 are formed in the connecting column 1 and the mounting piece 5, and the mounting piece 5 is fixedly connected to the connecting column 1 by screwing bolts into the plurality of first threaded holes 8. A plurality of second threaded holes 9 are formed in the bottom plate of the angle steel 3 and the connecting steel 2, and the angle steel 3 is fixedly connected to the connecting steel 2 by screwing bolts into the plurality of second threaded holes 9.

[0027] In this embodiment, clamping plates 11 are fixedly connected to opposite sides of the two protection plates 10, and a plurality of notches 12 are formed in the clamping plates 11 to prevent the nuts from blocking the clamping plates 11 when the clamping plates 11 are pushed into the angle steel 3.

[0028] In this embodiment, the widths of the plurality of notches 12 are all greater than the diameter of the nut. The clamping plates 11 are made of a triangular structure, and the clamping plates 11 are matched with the inner side of the angle steel 3. The clamping plates 11 can guide the installation of the protection plates 10.

[0029] In this embodiment, one end of the mounting rod 14 penetrates through the protection plate 10 and is provided with a flat slot, and the protruding part of the mounting rod 14 is parallel to the opening direction of the flat slot, which is convenient to judge the position of the protruding part of the mounting rod 14 from the outside and facilitates the disassembly of the protection plate 10 in the later stage.

[0030] It should be noted that the present utility model is a concealed steel structure connection node. When in use, first weld the reinforcing plate 6 at a preset position on the connecting column 1, then weld the partition plate 7 at a preset position on the connecting steel 2, then sleeve the mounting member 5 on the connecting column 1 and install and fix it with bolts, then weld one side of the angle steel 3 on the outer wall of the mounting member 5 and install the other side on the connecting steel 2 with bolts, then guide the two protective plates 10 through the clamping plates 11 and press them on both ends of the angle steel 3 respectively.
