[0002] The main function of bathroom partition walls is to separate spaces and provide a certain degree of privacy protection, rather than bearing loads and the weight of building structures. Bathroom partition walls can be made into other structural forms, but they cannot be changed into load-bearing structural walls without authorization. If bathroom partition panels are made into load-bearing walls, it will not only increase the construction difficulty and cost, but also affect the overall structural safety of the building due to the change in its structural form, resulting in a decrease in the stability of the building and an increase in safety hazards.

[0003] Although the bathroom partition wall cannot be made into a load-bearing wall, in order to ensure the safety of the building structure, the bathroom partition wall is also required to have sufficient stability. The traditional bathroom partition wall structure includes a ground beam 1´ and a partition wall 2´. For the traditional bathroom partition wall structure, the method of first pouring the ground beam 1´ and then constructing the partition wall 2´ is adopted. The specific construction process steps of the ground beam 1´ include: first fixing the embedded steel bars 11´ on the working surface floor through the embedded steel bar process, then tying the connecting steel bars 12´ on the embedded steel bars 11´, and finally setting the template for concrete pouring; the specific construction process steps of the partition wall 2´ include: first installing a galvanized square tube 21´ on the ground beam 1´ (horizontally and longitudinally erected and fixed to form), then installing a fixing plate 22´ on both sides of the galvanized square tube 21´, and pulling a wire mesh 23´ on both sides of the fixing plate 22´, and finally painting cement mortar on the wire mesh 23´ to form the partition wall 2´.

[0026] This exemplary embodiment describes a construction method for a cast-in-place structure of a bathroom partition wall. Figure 2 The construction flow chart shows that the frame components and casting templates of the same specification bathroom partition walls are completed by modular production and installation. Figure 3-5 , the construction method of the bathroom partition wall specifically includes the following steps: Step 1: Draw a construction drawing of the frame assembly 1. Draw a layout drawing of the frame assembly 1 including the vertical bars 11 and the horizontal bars 12 according to the size of the construction site, including: Draw a plurality of vertical bars 11 arranged side by side and perpendicular to the floor of the working surface, wherein the distance between two adjacent vertical bars 11 is between 350-400 mm, preferably 400 mm; Draw a plurality of cross bars 12 connected to the vertical bars 11, and the distance between two adjacent cross bars 12 is between 350-400 mm, preferably 400 mm; Step 2: Lay out and stake out on the floor slab of the working surface; Lay out the finished surface of the bathroom partition wall and lead it to the wall; Determine the base layer line by extrapolating inwards based on the size of the surface material; Step 3, installing the frame assembly 1 within the base line, including: According to the base surface line, select the vertical rod 11 with suitable specifications. The vertical rod 11 is preferably a galvanized square tube. The specific specifications are determined according to the size of the surface material, including 20mm×20mm, 25mm×25mm, 30mm×30mm, 40mm×40mm or 50mm×50mm. The wall thickness specifications are 1.0mm, 1.2mm, 1.5mm or 2.0mm, and the specification is preferably 30mm×30mm×1.5mm; Cut the vertical rod 11 to a length close to (or equal to) the height of the bathroom partition wall, with the error controlled within 10 mm, and open a plurality of circular holes along the length direction of the vertical rod 11; Select a crossbar 12 that matches the specifications of the vertical bar 11, and cut the crossbar 12 to a length close to (or equal to) the width of the partition wall, with the error controlled within 10 mm; Drill holes on the work surface floor and fix the corner bracket 5 on the work surface floor. When fixing and installing the corner bracket 5, two adjacent corner brackets 5 are arranged relative to each other to ensure the installation stability of the frame assembly 1, thereby ensuring the stability of the bathroom partition wall formed during the pouring process; the installed corner bracket 5 adopts a three-leg corner bracket, such as Figure 6-7 As shown, it includes a main leg 51 and branch legs 52 arranged on both sides of the main leg 51, the branch legs 52 on both sides are symmetrically arranged, the main leg 51 and the branch legs 52 are an integrated structure, the main leg 51 and the branch legs 52 are both right-angled L-shaped, including a first right-angled side and a second right-angled side, the first right-angled side of the main leg 51 and the first right-angled side of the branch leg 52 are arranged on the same plane side, the first right-angled side of the main leg 51 is longer than the first right-angled side of the branch leg 52, the second right-angled side of the main leg 51 and the second right-angled side of the branch leg 52 are arranged on the other side of the same plane, and a gap is left between the second right-angled side of the main leg 51 and the second right-angled side of the branch leg 52, which can ensure that when concrete is poured later, concrete can be accommodated between the main leg 51 and the branch leg 52, so that the legs are completely embedded in the concrete, thereby increasing the structural strength of the bathroom; The vertical rod 11 is welded to the angle bracket 5. During welding, the end of the vertical rod 11 is aligned with the first right angle side of the main leg 51 and the second right angle side of the main leg 51. The welding is performed at the aligned part to remove the excess welding slag. Pass the horizontal rod 12 through the circular hole 1 on the corresponding vertical rod 11 in sequence; Step 4: Install water and electricity embedded parts; Install the pre-buried water and electricity pipelines according to the water and electricity construction drawings and protect them to prevent concrete from entering the junction box when pouring concrete layer 4; Step 5: Install the casting template 2 on both sides of the frame assembly 1; Cut out a casting template 2 corresponding to the size of the partition wall, and bolt the casting template 2 to the vertical rod 11 using dovetail bolts 6; Step 6: Install the support member 3 on the outer side of the casting template 2; Install the support member 3 on the outer side of the casting formwork 2, and fasten the support members 7 on both sides with through bolts 7; Step 7, pouring a concrete layer 4 in the spacing space between the inner side of the casting template 2 and the frame assembly 1; When pouring the concrete layer 4, adopt layered pouring to avoid bursting of the mold making the base surface uneven and affecting the subsequent construction.

[0028] The present embodiment also provides a method for installing the frame assembly 1. The frame assembly 1 is prefabricated in a factory by splicing the horizontal bars 12 and the vertical bars 11 to form an overall modular structure. The structure is then installed as a whole after the angle brackets 5 are fixed on site. This method can further improve the installation and construction efficiency of the frame assembly 1.
