Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to a roof parapet galvanized square steel water retaining edge structure and a construction method thereof. Background Art

[0002] The waterproof edge of the parapet wall on the roof is to prevent the roll material from falling off and rainwater from penetrating. The traditional method is to reserve grooves or pressure strips on the parapet wall to fix and seal with glue. This method is difficult to construct. It cannot ensure horizontal and vertical alignment during the concrete pouring process. The part covered by the concrete needs to be chiseled off, and the molding effect is not beautiful. The roll material in the groove is exposed to the wind and rain all year round, and it is easy to age and crack, causing roof leakage. Summary of the invention

[0003] The purpose of the present invention is to provide a roof parapet galvanized square steel water retaining edge structure and a construction method thereof to solve the above-mentioned problems.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] The present invention discloses a roof parapet galvanized square steel water retaining edge structure and a construction method thereof, comprising the following steps:

[0006] S1. Set up a level, mark the elevation of the lower end of the galvanized square steel on the parapet, unify the elevation of the entire roof, and pop out the ink line;

[0007] S2, plant 8-11cm long steel bars with a spacing of 1.2-2cm close to the lower part of the ink line, and extend 2cm into the parapet;

[0008] S3. Place the galvanized square steel on the steel bar, weld the lower part to the steel bar and fix it, and apply anti-rust paint;

[0009] S4. Use infrared rays to calibrate the elevation of the galvanized square steel. Keep the edge of the galvanized square steel 8-11cm away from the inner side of the parapet so that the outer side of the galvanized square steel is in line.

[0010] S5. After welding, the aluminum alloy eagle beak is anchored on the lower part of the galvanized square steel edge, and the aluminum alloy eagle beak is fixed with rivets every 500mm to form a complete roll waterproofing device;

[0011] S6. After all installation is completed, the upper part of the galvanized square steel is sloped inward at an angle of 8-12%. After the ink line is popped out, the surface is plastered with anti-cracking mortar to keep the overall slope of the water retaining wall smooth.

[0012] Furthermore, the length of the steel bar is 8cm, and the steel bar is implanted close to the lower part of the ink line with a spacing of 1.2cm, extending into the parapet 2cm, and the 30*60mm galvanized square steel is placed on the steel bar, the lower part is welded and fixed to the steel bar, and anti-rust paint is applied. The elevation of the galvanized square steel is corrected by infrared rays, and the edge of the galvanized square steel is kept 8cm away from the inner side of the parapet so that the outer side of the galvanized square steel is kept in line. After all the installation is completed, the upper part of the galvanized square steel is sloped inward at an 8% slope.

[0013] Furthermore, the length of the steel bar is 9cm, and the steel bar is implanted close to the lower part of the ink line with a spacing of 1.5cm, extending into the parapet 2cm, and the 40*70mm galvanized square steel is placed on the steel bar, the lower part is welded and fixed to the steel bar, and anti-rust paint is applied. The elevation of the galvanized square steel is corrected by infrared rays, and the edge of the galvanized square steel is kept 9cm away from the inner side of the parapet so that the outer side of the galvanized square steel is kept in line. After all the installation is completed, the upper part of the galvanized square steel is sloped inward at a slope of 10%.

[0014] Furthermore, the length of the steel bar is 10cm, and the steel bar is implanted close to the lower part of the ink line with a spacing of 1.8cm, extending into the parapet 2cm, and the 50*80mm galvanized square steel is placed on the steel bar, the lower part is welded and fixed to the steel bar, and anti-rust paint is applied. The elevation of the galvanized square steel is corrected by infrared rays, and the edge of the galvanized square steel is kept 10cm away from the inner width of the parapet so that the outer side of the galvanized square steel is kept in line. After all the installation is completed, the upper part of the galvanized square steel is sloped inward at an 11% slope.

[0015] The galvanized square steel water retaining edge structure of the roof parapet is manufactured according to the above method.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are:

[0017] The invention can be constructed quickly, can ensure horizontal and vertical alignment during the concrete pouring process, has a beautiful molding effect, can effectively prevent the coiled material from being exposed to the outside and being eroded by wind and rain, and prevents roof leakage.
