Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a standardized template device for the construction of bathroom micro-sloping slabs. Background Technology
[0002] With the development of building technology, the micro-sloping slab design has cleverly concealed drainage pipes, preventing them from being exposed on the bathroom floor. This not only improves aesthetics and makes efficient use of space, but also effectively reduces drainage noise affecting downstairs neighbors and facilitates future pipe maintenance. Micro-sloping slabs and in-floor drainage technology have become widely used in bathrooms. Currently, most micro-sloping slab construction projects still use traditional wooden or ordinary steel formwork, which has the following problems: wooden formwork is prone to deformation, leading to large errors in the sloping slab elevation and requiring repeated adjustments; ordinary steel formwork is prone to grout leakage at joints, resulting in poor surface flatness; and the formwork for thin-layer micro-sloping slabs is difficult to support, with traditional formwork often being unstable and prone to floating. There is a market need for a standardized formwork device specifically designed for micro-sloping slab construction. Utility Model Content
[0003] This utility model provides a standardized template device for the construction of bathroom micro-drop slabs, in order to solve the technical problems of templates being easily deformed, easily disturbed, difficult to support, and prone to floating in actual construction sites.

The cross braces are set inside the square frame, and the four ends of the cross braces are fixed to the four sides of the square frame. The square frame includes horizontal and vertical wing plates, which are galvanized angle steel. Two horizontal wing plates and two vertical wing plates are welded end to end to form the square frame. The four ends of the cross braces are welded and fixed to the two horizontal and two vertical wing plates respectively.

[0023] A standardized formwork device for the construction of bathroom micro-drop slabs, such as Figures 1 to 2 As shown, the structure includes a square frame 1, cross braces 2, and anti-buoyancy and anti-slip components. The cross braces 2 are installed inside the square frame 1, and their four ends are fixed to the four sides of the square frame 1. The square frame includes horizontal wing plates 3 and vertical wing plates 4, which are galvanized angle steel. The square frame 1 is formed by welding two horizontal wing plates 3 and two vertical wing plates 4 end to end. The four ends of the cross braces 2 are welded and fixed to the two horizontal wing plates 3 and two vertical wing plates 4, respectively. The two horizontal wing plates 3 and two vertical wing plates 4 are fixedly connected to the toilet template through the anti-buoyancy and anti-slip components.
[0024] Furthermore, the anti-buoyancy and anti-slip component consists of multiple tie bolts 5, and threaded holes are provided on the two horizontal wing plates 3 and the two vertical wing plates 4. The two horizontal wing plates 3 and the two vertical wing plates 4 are fixedly connected to the toilet template respectively through the threaded holes by the tie bolts 5.
[0025] Furthermore, laser graduation lines 8 are provided on the outer surface of the vertical wing plate 4.
[0026] Furthermore, the weld seams where the two horizontal wing plates 3 and the two vertical wing plates 4 are welded end to end are pressed with sealing strips.
[0027] This invention first involves cutting galvanized angle steel into two horizontal flanges 3 and two vertical flanges 4 according to the dimensions of the bathroom slab. The two horizontal flanges 3 and two vertical flanges 4 are then welded end-to-end to form a square frame 1, with sealing strips 8 pressed tightly at the four corner welds. Two steel bars with a diameter of not less than 20mm are cut into two steel bars according to the dimensions of the bathroom slab, and these two steel bars are vertically welded inside the square frame 1 to form a cross brace 2. The four ends of the cross brace 2 are welded to the middle positions of the two horizontal flanges 3 and the two vertical flanges 4, respectively. After placing the square frame 1 with the welded cross braces 2 inside, the horizontal flanges 3 and vertical flanges 4 are fixed to the template using tie bolts 5 to prevent slippage and deformation of the square frame 1. Next, a special positioning ruler is used to check and fine-tune the elevation. Finally, concrete is poured, and after the concrete reaches the required strength, the template is removed for reuse. Compared to traditional wooden formwork, this invention is less prone to deformation, floating, and grout leakage, resulting in smaller construction errors and better concrete forming. Compared to traditional steel formwork, this invention has less grout leakage at joints, better surface flatness, and solves the problem of difficult formwork support for thin-layer micro-sloping slabs, making it more suitable for micro-sloping slab construction. This invention offers precise elevation control with laser-etched graduations on the outer surface of the formwork for easy elevation control; it features a specialized grout leakage prevention design with sealing strips at joints; and it boasts high reusability, with galvanized material allowing for over 50 reuses, reducing construction costs.
