Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to an ultra-thin same-layer drainage floor drain steel frame structure and a construction method. Background Art

[0002] Same-floor drainage refers to the drainage pipes (including sewage horizontal pipes and drainage branches) of sanitary appliances in the bathroom do not pass through the floor slab to enter the lower space, but are laid on the same floor as the sanitary appliances and connected to the drainage riser in the suite of this floor. The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important component of the drainage system in the house, it is also widely used in the same-floor drainage system.

[0003] At present, when constructing the floor slab, it is necessary to support the formwork first, then tie the steel bars, pour the concrete, and finally install the floor drain. The floor slab constructed by this method is thicker overall. Especially for some lofts, because the height of the loft is fixed, when the floor slab is thicker, it will affect the height of the upper space. Therefore, in order to reduce the overall thickness of the floor slab, the floor drain is generally designed to be sunken. Since the steel bars are generally located at the bottom of the floor slab, in order not to affect the strength of the floor slab, in general, the sinking and embedding size of the floor drain should be smaller than the total thickness of the floor slab minus the thickness from the top of the steel bars to the bottom of the floor slab, that is, the bottom surface of the floor drain cannot be lower than the steel bar layer. The thickness of the floor slab constructed by this method is basically above 20cm. Therefore, how to reduce the overall thickness of the floor slab is a problem that has been under study. Summary of the invention

At the same time, the waterproof protective layer also protects the waterproof membrane. The laying of the expanded clay area around the floor drain can strengthen the support around the floor drain and avoid the situation where water seepage around the floor drain causes depression.

[0019] By adopting the above technical solution, the waterproof membrane and the floor drain can be connected through the seal, so that the sealing between the two is better, and water is prevented from leaking from between the waterproof membrane and the floor drain into the supporting structure.

[0020] Optionally, the sealing member includes a sealing ring and fixing bolts connecting the sealing ring, the waterproof membrane and the main body as a whole, and the sealing ring is located on a side of the waterproof membrane away from the main body.

[0021] By adopting the above technical solution, the sealing ring, the waterproof membrane and the main body can be connected as one through the fixing bolts, which makes the installation very convenient.

The mounting plate 12 can be made of a steel plate, and the fixed connection between the steel plate and the steel structure frame 11 can be achieved by welding the steel plate and the steel structure frame 11 together. The support member 4 includes two support rods, which are parallel to each other and fixedly connected to the mounting plate 12.

When in use, the floor drain 3 is directly placed on two support rods, and the limiting portion 34 is embedded between the two support rods, so that the floor drain 3 can be limited. In addition, the setting of the support rods can also strengthen the supporting strength of the floor drain 3.

[0052] During installation, the mounting plate 12 is directly fixed to the steel structure frame 11, and then the drain pipe 5 is placed inside the steel structure frame 11 from the gap of the steel structure frame 11, the floor drain 3 is placed on the two support rods and the limiter 34 is embedded between the two support rods, and the water outlet of the floor drain 3 is connected to the drain pipe 5. Finally, concrete is poured in the steel structure frame 11, and the concrete can connect the drain pipe 5, the floor drain 3 and the steel structure frame 11 as a whole, and the installation is more stable.

[0053] At the same time, in order to strengthen the overall support strength of the floor slab, a load-bearing plate 14 is also provided on the steel structure frame 11. The load-bearing plate 14 can be directly placed on the steel structure frame 11, and the load-bearing plate 14 and the steel structure frame 11 are connected as a whole by pouring a concrete layer 13.

[0055] The waterproofing coiled material 21 is sleeved on the floor drain 3 and laid on the concrete layer 13 above the load-bearing plate 14. The waterproofing coiled material 21 is bent from the direction away from the floor drain 3 to the direction where the floor drain 3 is located and finally fixed to the main body 31, so that a depression is formed at one end of the waterproofing coiled material 21 close to the floor drain 3, so as to prevent the water leaking from the side wall of the floor drain 3 to the space between the floor slab and the floor drain 3 from spreading along the waterproofing coiled material 21 and causing excessive damage to the floor slab. The waterproofing coiled material 21 is sleeved on the connecting pipe 33 and its lower surface is fixed to the upper surface of the main body 31.

The arrangement of the sealing ring 61 can make the sealing between the waterproof coiled material 21 and the main body 31 better, and avoid the situation where the sealing between the waterproof coiled material 21 and the main body 31 is not tight between two adjacent fixing bolts 62.

[0057] The waterproof protective layer 22 is laid on the waterproof coiled material 21 and on the upper surface of the sealing ring 61. The waterproof protective layer 22 can be made of fine stone concrete material, which can play a role of isolating and protecting the waterproof coiled material 21. At the same time, a ceramsite area 25 is laid around the floor drain 3. The ceramsite area 25 is laid above the end of the waterproof protective layer 22 close to the floor drain 3. The ceramsite has a high strength and can support the floor slab to prevent water from seeping from the side wall of the floor drain 3 and causing depressions around the floor drain 3.

[0058] The adhesive 23 is laid on the waterproof protective layer 22 and is laid around the floor drain 3. The decorative layer 24 is laid on the adhesive 23. The adhesive 23 can fix the decorative layer 24, making the decorative layer 24 more stable. The decorative layer 24 can be made of ceramic tiles or other products as needed.
