Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a waterproof detail construction method for a portion where a steel column is higher than a metal roof. Background Art

[0002] There are more and more steel structure projects such as high-rise residential buildings, shopping malls, sports stadiums, landmark exhibition halls, etc., and the quality problems that come with them are also increasing. Among them, roof leakage is one of the common problems. The steel columns that pass through the metal roof are the weak points of waterproofing. The existing patent CN116838038A - a waterproofing method for metal roofs, provides a waterproof structure for the column part of the metal roof, which is to fix a water retaining plate on the column. The water retaining plate is located above the metal roof, and sealing rings, sealants, etc. are set in the space between the water retaining plate, the column and the metal roof to achieve waterproofing. However, as the building structure settles in the later stage, it is easy to cause the position of the water retaining plate, the column and the metal roof to be misaligned, causing the waterproof part to crack and leak. Summary of the Invention

[0003] In response to the above problems, an embodiment of the present invention provides a method for constructing waterproof details in which steel columns protrude above a metal roof.

[0004] An embodiment of the present invention provides a method for constructing waterproof details in a portion where a steel column protrudes above a metal roof, comprising: fabricating a first waterproof structure and a second waterproof structure according to the size of the steel column, wherein the first waterproof structure comprises a semicircular arc plate adapted to the outer circumference of the steel column, wherein one arc-shaped side of the semicircular arc plate is sloped gradually from the bottom of the arc toward the opening, and a supporting plate conforming to the shape of the semicircular arc plate is provided on the arc-shaped side, and a lap plate is provided on the supporting plate along the extension line of the end of the semicircular arc plate; the second waterproof structure is identical to the first waterproof structure, except that the slope of the second waterproof structure is gradually sloped from the opening toward the bottom of the arc;

[0005] The first waterproof structure and the second waterproof structure are butted together at the junction of the steel column and the metal roof. During the butt jointing process, the lap plate of the first waterproof structure is overlapped with the lap plate of the second waterproof structure. After butt jointing, the slope direction of the two bearing plates is the same as the downstream direction of the metal roof.

[0006] Waterproof rubber gaskets are arranged between the first waterproof structure and the steel column, and between the second waterproof structure and the steel column, and the first waterproof structure and the second waterproof structure are fixed on the steel column;

[0007] The metal roof is constructed in the direction of water flow as designed. For the two metal roof panels at the steel column position, one metal roof panel is overlapped on the upper surface of the bearing plate of the first waterproof structure, and the other metal roof panel is overlapped on the lower surface of the bearing plate of the second waterproof structure, thereby completing the waterproof detail construction.

[0008] Compared with the prior art, the beneficial effects of the present invention are: the waterproof details of the present invention are simple in structure, and the manufacturing method and construction are convenient; in addition, the first waterproof structure, the second waterproof structure and the steel column are fixed as one, and the metal roof panel here adopts an overlapping method, which can better adapt to the later settlement deformation, ensure the waterproof performance, and effectively solve the problem of weak waterproofing at the intersection of the metal roof and the steel column.

[0009] Optionally, the overlapping length of the first waterproof structure and the second waterproof structure is not less than 50 mm.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0021] An embodiment of the present invention provides a method for constructing waterproof details where a steel column protrudes above a metal roof, comprising:

[0022] Step 1: Make the first waterproof structure 2 and the second waterproof structure 3 according to the size of the steel column 1, wherein, see Figure 1 and Figure 2 The first waterproof structure 2 includes a semicircular arc plate adapted to the outer periphery of the steel column 1, and an arc-shaped side of the semicircular arc plate is in a slope shape that gradually decreases from the bottom of the arc to the opening, and a supporting plate that matches its shape is provided on the arc side, and a lap plate is extended on the supporting plate along the extension line of the end of the semicircular arc plate; the second waterproof structure 3 has the same structure as the first waterproof structure 2, the only difference is that the slope in the second waterproof structure 3 gradually decreases from the opening to the bottom of the arc.

[0023] During implementation, the first waterproof structure 2 and the second waterproof structure 3 can be cold-pressed as a whole using galvanized aluminum plates. The diameter of the semicircular arc plate is slightly larger than the diameter of the steel column 1, such as larger than 2 mm; the maximum height of the semicircular arc plate is about 150 mm, and the overlapping length is not less than 50 mm. In this way, when overlapping between the first waterproof structure 2 and the second waterproof structure 3, the overlapping length is not less than 50 mm.

[0024] Step 2: dock the first waterproof structure 2 and the second waterproof structure 3 at the junction of the steel column 1 and the metal roof. During the docking process, the lap plate of the first waterproof structure 2 is overlapped on the lap plate of the second waterproof structure 3. After docking, the slope direction of the two bearing plates is the same as the downstream direction of the metal roof.

[0025] Step three: arrange waterproof rubber gaskets between the first waterproof structure 2 and the steel column 1 and between the second waterproof structure 3 and the steel column 1 , and fix the first waterproof structure 2 and the second waterproof structure 3 on the steel column 1 .

[0026] During implementation, the waterproof rubber gasket can ensure the waterproof performance of the entire structure, that is, a waterproof rubber sleeve is put on the steel column, and the overall thickness is about 4mm.

[0027] When fixing, the semicircular arc plate is clamped and fixed to the steel column 1 by using a metal clamp 4, and the first waterproof structure 2 and the second waterproof structure 3 are fixed to the steel column 1. Figure 3 shown.

[0028] Step 4: Construct the metal roof in the direction of the water flow as designed. For the two metal roof panels 5 at the position of the steel column 1, one metal roof panel 5 is overlapped on the upper surface of the bearing plate of the first waterproof structure 2, and the other metal roof panel 5 is overlapped on the lower surface of the bearing plate of the second waterproof structure 3, thereby completing the construction of the waterproof detail structure. The overall effect is as follows: Figure 4 shown.

[0029] During implementation, the overlapping length of the two metal roof panels 5 at the position of the steel column 1 in the downstream direction is not less than 150 mm, that is, a lap joint structure is formed in which the two ends of the bottom of the upper metal roof panel 5 extend downward beyond the lap joint of the first waterproof structure 2, and the two ends of the upper part of the lower metal roof panel 5 extend upward beyond the lap joint of the second waterproof structure 3, thereby ensuring waterproof performance.

[0030] During implementation, each overlapping position can be fastened with self-tapping screws, and weather-resistant glue can be applied to the outside of the self-tapping screws for sealing. When fixing, self-tapping screws can be respectively set at the overlapping positions of the metal roof panel 5 and the first waterproof structure 2, the first waterproof structure 2 and the second waterproof structure 3, and the second waterproof structure 3 and the metal roof panel 5, and staggered with each other. For example, in the downstream direction, the self-tapping screws at the overlapping position of the metal roof panel 5 and the first waterproof structure 2 are at the rear side, the self-tapping screws at the first waterproof structure 2 and the second waterproof structure 3 are in the middle position, and the self-tapping screws at the second waterproof structure 3 and the metal roof panel 5 are at the front. In this way, even if leakage occurs at the self-tapping screw position above, the seepage will be guided away along the second waterproof structure 3 and the metal roof panel 5 below to ensure waterproof performance.

[0031] During implementation, weather-resistant glue can be applied to seal the joints between the first waterproof structure 2 and the steel column 1, the joints between the second waterproof structure 3 and the steel column 1, the joints between the metal roof panel 5 and the steel column 1, and the joints at each overlapping position to enhance waterproofing.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
