Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a connection node of wall square tube purlins used in steel structure buildings. Background Art

[0002] Steel structure buildings are increasingly widely used in various industries and fields. Compared with concrete structures, steel plates or steel sections are used instead of reinforced concrete, which have higher strength and better earthquake resistance. The components can be processed in factories and installed on site, which greatly shortens the construction period, reduces on-site labor, and is more energy-saving, green and environmentally friendly.

[0003] However, due to the different process requirements of various industries, more and more industrial plants have parapets, and internal gutters are set inside the parapets. The existing parapet inner panels of the existing eaves wall are generally fixed by setting wall beams on the parapet columns. The cross-section of the wall beam is selected according to the span of the plant. It is generally C-shaped steel or double-hugging C-shaped steel, and the C-shaped steel or double-hugging C-shaped steel is connected to the parapet columns by bolts. When the distance between the upper wall beam and the gutter is close, a wall beam is usually set. However, this construction method not only wastes materials, but also is inconvenient for on-site installation. A tie rod system needs to be set between the two wall beams, and the flatness is not easy to control. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

[0005] Connection nodes for square tube purlins on the walls of steel structure buildings, including inner gutters, auxiliary bending parts, self-tapping screws, parapet inner panels, parapet columns and wall beams;

[0006] The top surface of the inner gutter has an inner flange near the parapet column, the self-tapping screws connect the horizontal part of the auxiliary bending part with the inner flange, the self-tapping screws connect the vertical part of the auxiliary bending part, the lower end of the parapet inner plate and the parapet column, and the wall beam is located at the top of the parapet column.

[0007] As an improvement of the above technical solution, the vertical distance between the wall beam and the inner gutter is less than 1m.

[0008] As an improvement of the above technical solution, the thickness of the auxiliary bending part is ≥2mm, the surface of the auxiliary bending part is galvanized, and the material and the amount of galvanizing are the same as the wall beam.

[0009] As an improvement of the above technical solution, the spacing between the self-tapping screws is ≤250mm.

[0010] As an improvement of the above technical solution, the thickness of the inner gutter is ≥2mm.

[0011] Beneficial effects of the utility model:

[0012] 1. In order to replace the wall beam at the lower end of the existing parapet inner plate, an inner flange is set on the top surface of the inner gutter near the parapet column, and then the horizontal part of the auxiliary bending part, which is easy to process and has easy-to-obtain materials, is fixed to the inner flange through self-tapping screws, while the vertical part of the auxiliary bending part is integrally fixedly connected to the parapet inner plate and the parapet column through self-tapping screws, thereby realizing the integral connection of the lower end of the parapet inner plate, the parapet column and the inner gutter.

[0013] 2. Compared with the solution of increasing structural stability by setting a wall beam, this solution is relatively more time-saving and material-saving, and is convenient and efficient to install. In addition, the auxiliary bending parts are fixed on the inner turning edge, and the flatness of this solution is easier to control than the bracing system required for setting the wall beam.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0017] The existing parapet wall inner plate is usually fixed by setting a wall beam on the parapet wall column. The cross section of the wall beam is selected according to the span of the factory building. It is usually C-shaped steel or double-hugging C-shaped steel. The C-shaped steel or double-hugging C-shaped steel is connected to the parapet wall column by bolts. When the upper wall beam is close to the gutter, a wall beam is also set. However, this construction method not only wastes materials, but also is inconvenient to install on site. A brace system needs to be set between the two wall beams.

[0018] See also Figure 1 As shown, the utility model provides a technical solution for connecting nodes of square tube purlins on the wall of a steel structure building:

[0019] A connection node for wall square tube purlins of a steel structure building, comprising an inner gutter 1, an auxiliary bending piece 2, a self-tapping screw 3, a parapet inner plate 4, a parapet column 5 and a wall beam 6;

[0020] The top surface of the inner gutter 1 has an inner flange 7 near the parapet column 5. The self-tapping screws 3 connect the horizontal part of the auxiliary bending part 2 with the inner flange 7. The self-tapping screws 3 connect the vertical part of the auxiliary bending part 2, the lower end of the parapet inner plate 4 and the parapet column 5. The wall beam 6 is located at the top of the parapet column 5.

[0021] In order to replace the wall beam 6 at the lower end of the existing parapet inner plate 4, this scheme sets an inner flange 7 on the top surface of the inner gutter near the parapet column 5. Preferably, the width of the inner flange 7 is 30 mm. The horizontal part of the auxiliary bending part 2, which is easy to process and has readily available materials, is fixed to the inner flange 7 by self-tapping screws 3, and the vertical part of the auxiliary bending part 2 is integrally fixedly connected to the parapet inner plate 4 and the parapet column 5 by self-tapping screws 3, thereby realizing the integral connection between the lower end of the parapet inner plate 4, the parapet column 5 and the inner gutter 1.

[0022] Compared with the solution of increasing the structural stability by setting a wall beam 6, this solution is relatively more time-saving and material-saving, and is convenient and efficient to install. In addition, the auxiliary bending member 2 is fixed on the inner flange 7, and compared with the bracing system required for setting the wall beam 6, the flatness of this solution is easier to control.

[0023] Since this solution is for the case where the distance between the upper wall beam and the gutter is relatively close, the effect of this solution is best when the vertical distance between the wall beam 6 and the inner gutter 1 is less than 1m, that is, when L≤1. In addition, the plate thickness of the inner gutter 1 is ≥2mm to provide better structural strength. Preferably, the plate thickness of the inner gutter 1 is 2mm.

[0024] In one embodiment, the auxiliary bending member 2 has a thickness of ≥2 mm, the surface of the auxiliary bending member 2 is galvanized, and the material and the amount of galvanization are the same as those of the wall beam 6. Preferably, the thickness of the auxiliary bending member 2 and the wall beam 6 are both 2 mm.

[0025] The surface galvanizing is to improve the anti-corrosion performance, and the same amount of galvanizing is achieved by galvanizing the auxiliary bending member 2 and the wall beam 6 simultaneously, which reduces the time spent on galvanizing separately. Preferably, the auxiliary bending member 2 and the wall beam 6 are made of steel.

[0026] The actual installation process of this solution is as follows:

[0027] Step 1: an inner flange 7 is provided at the inner gutter 1 near the parapet column 5, and the width of the inner flange 7 is ≥30 mm;

[0028] Step 2: The self-tapping screws 3 fix the horizontal part of the auxiliary bending part 2 on the inner flange 7, and the distance between two adjacent self-tapping screws 3 is ≤250mm;

[0029] Step three: The self-tapping screws 3 fix the vertical part of the auxiliary bending part 2, the parapet inner plate 4 and the parapet column 5 as a whole, and the distance between two adjacent self-tapping screws 3 is ≤250mm.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
