Description

Technical Field

[0001] The utility model relates to the technical field of ground construction, in particular to an indoor ground geothermal floor construction structure. Background Art

[0002] Geothermal pipe heating systems are becoming more and more mature and are being adopted by more and more families; however, in the actual use of floor heating equipment, since the floor is laid on the ground radiation heating system and is subjected to temperatures above 40°C for a long time, the construction structure of the geothermal floor will directly affect the service life of the geothermal floor. Currently, the design of the geothermal floor construction structure is still imperfect.

[0003] The waterproof performance of geothermal floor construction structure should be considered. The better the waterproof performance of geothermal floor construction structure, the smaller the expansion and contraction of the floor will be, and the less the phenomenon of seam pulling and arching will be in geothermal environment.

[0004] In addition, ordinary foam plastic mats cannot be used as floor mats between the ground and the floor. Special paper mats for geothermal heating must be used because these mats conduct heat quickly and do not deform. Ordinary foam mats conduct heat slowly and are prone to produce harmful gases when exposed to high temperatures for a long time, endangering the health of users.

[0005] For this purpose, the utility model proposes an indoor ground geothermal floor construction structure. Utility Model Content

[0006] In order to solve the problems existing in the prior art, the utility model provides an indoor ground geothermal floor construction structure with reasonable structural design.

[0007] The technical solution of the utility model is as follows:

[0008] An indoor ground geothermal floor construction structure comprises a bathroom floor construction structure, a bedroom floor construction structure and a bathroom-bedroom floor construction structure arranged between the bathroom and the bedroom; the bathroom floor construction structure, the bedroom floor construction structure and the bathroom-bedroom floor construction structure all comprise a JS waterproof layer A arranged on a structural floor slab, a protective extruded board arranged on the JS waterproof layer, a fine stone concrete layer arranged on the protective extruded board, and a JS waterproof layer B arranged on the fine stone concrete layer; the bathroom-bedroom floor construction structure also comprises a water stop sill arranged on the structural floor slab and located at the junction of the bathroom and the bedroom, and the JS waterproof layer A is coated on the water stop sill; the fine stone concrete layer at the bathroom-bedroom floor construction structure is provided with a step surface, and the side close to the bedroom is higher than the side close to the bathroom.

[0009] Furthermore, the bathroom floor construction structure and the bathroom-bedroom floor construction structure also include an adhesive layer, which is arranged above the JS waterproof layer B, and a stone decorative panel 1 is laid on the adhesive layer within the bathroom area, and a stone decorative panel 2 is laid on the adhesive layer at the junction of the bathroom and the bedroom, one end of the stone decorative panel 2 is pressed on the stone decorative panel 1, and a waterproof sealant is filled at the junction of the stone decorative panel 1 and the stone decorative panel 2.

[0010] Furthermore, the bathroom floor construction structure, bedroom floor construction structure and bathroom and bedroom floor construction structure also include floor heating pipe installation components, and the floor heating pipe installation components include floor heating pipes and plastic staples. A group of the floor heating pipes are respectively arranged on the protective extruded board through plastic staples.

[0011] Furthermore, the fine stone concrete layer of the bedroom floor construction structure is flush with the adhesive layer of the bathroom floor construction structure, a geothermal floor mat is laid on the fine stone concrete layer of the bedroom floor construction structure, and a geothermal floor is laid on the geothermal floor mat.

[0012] Furthermore, the geothermal floor is located close to the wall and is fixed to the geothermal floor mat by PVC clips.

[0013] Furthermore, a steel mesh is provided in the fine stone concrete layer, which can enhance the strength of the fine stone concrete layer and prevent cracking; a radiation film is laid on the protective extruded board to prevent heat from losing downwards.

[0014] Furthermore, the fine stone concrete layer of the bathroom and bedroom floor construction structure is reserved with expansion joints. Since the temperature rises when the geothermal system is running and returns to room temperature when it is shut down, thermal expansion and contraction are prone to occur. The expansion joints can effectively prevent the fine stone concrete layer from deformation and cracking.

[0015] Furthermore, the cross-section of the waterstop is a triangular structure. During on-site construction, there is an embedded stainless steel waterstop plate at the bottom of the waterstop. At the interface with the wall and the floor, waterproof mortar is used to make bevels along both sides of the waterstop plate to form a triangle.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1) By setting a water stop on the structural floor, it is possible to prevent water from seeping from the bathroom into the bedroom through the fine stone concrete layer and prevent the geothermal floor from getting damp.

[0018] 2) By applying JS waterproof coating on the structural floor and fine stone concrete layer, water can be prevented from seeping into the fine stone concrete layer and the structural floor on the bathroom floor.

[0019] 3) By setting a step surface on the fine stone concrete layer at the junction of the bathroom and the bedroom, it can effectively prevent water from accumulating in the bathroom from entering the bedroom.

[0020] 4) Use a special geothermal floor mat under the geothermal floor to prevent the mat from deforming and affecting the service life of the geothermal floor.

[0021] 5) Expansion joints are set in the fine stone concrete layer to prevent cracking of the ground and effectively ensure the stability of the geothermal floor. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described below in conjunction with the accompanying drawings of the specification.

[0026] like Figure 1 As shown, an indoor ground geothermal floor construction structure includes a bathroom floor construction structure arranged within the bathroom area, a bedroom floor construction structure arranged within the bedroom area, and a bathroom-bedroom floor construction structure arranged at the junction between the bathroom and the bedroom;

[0027] The bathroom floor construction structure, the bedroom floor construction structure and the bathroom and bedroom floor construction structure all include a JS waterproof layer A2 arranged on the structural floor 1, a protective extruded board 3 arranged on the JS waterproof layer, a fine stone concrete layer 4 arranged on the protective extruded board 3, and a JS waterproof layer B6 arranged on the fine stone concrete layer 4; in this embodiment: a steel mesh 5 is provided in the fine stone concrete layer 4, and a radiation film is laid on the protective extruded board 3.

[0028] The floor construction structure of the bathroom and bedroom also includes a waterstop 13, that is, a waterstop 13 is set on the structural floor 1 at the threshold where the bedroom and the bathroom meet, and the bathroom and the waterstop are painted around and in the corners (there may be small holes around and in the corners of the bathroom that are not tight, and the waterstop steel plate is embedded in the wall and floor with grooves, so it is necessary to use the leak-stopper first and then apply the waterproof paint to enhance the effect). After drying, apply two coats of JS waterproof paint (JS waterproof layer A2) at a height of 300mm on the floor and wall, and extend it to 500mm in the bedroom and 200mm on both sides (the walls on both sides of the bedroom door); after the floor heating construction is backfilled, apply the third coat of JS waterproof paint (JS waterproof layer B6) on the backfill layer (fine stone concrete layer 4).

[0029] It should be noted that the principle of Leak-proof King is to form a highly elastic film on the surface of the building structure with water leakage to prevent water from entering the building structure. Waterproof coating uses the chemical substances contained in its coating to block the cracks in the building to prevent water from penetrating.

[0030] The fine stone concrete layer 4 at the floor construction structure of the bathroom and bedroom is provided with a step surface, and the side close to the bedroom is higher than the side close to the bathroom, so as to prevent water seepage from the bathroom from entering the bedroom along the fine stone concrete layer 4.

[0031] The bathroom floor construction structure and the bathroom-bedroom floor construction structure also include an adhesive layer 7, which is arranged above the JS waterproof layer B6, and a stone decorative panel 8 is laid on the adhesive layer 7 within the bathroom area, and a stone decorative panel 2 10 (threshold stone) is laid on the adhesive layer 7 at the junction of the bathroom and the bedroom, one end of the stone decorative panel 2 10 is pressed on the stone decorative panel 1 8, and the junction between the stone decorative panel 1 8 and the stone decorative panel 2 10 is filled with waterproof sealant 9 to prevent water from seeping into the bedroom from under the threshold stone.

[0032] The bathroom floor construction structure, bedroom floor construction structure and bathroom-bedroom floor construction structure also include floor heating pipe installation components, which include floor heating pipes 12 and plastic staples 11. A group of floor heating pipes 12 are respectively arranged on the protective extruded board 3 through plastic staples 11.

[0033] like Figure 1-2 As shown, the fine stone concrete layer 4 of the bedroom floor construction structure is flush with the adhesive layer 7 of the bathroom floor construction structure, a geothermal mat 15 is laid on the fine stone concrete layer 4 of the bedroom floor construction structure, and a geothermal floor 16 is laid on the geothermal mat 15; the geothermal floor 16 is close to the wall and is fixed to the geothermal mat 15 by PVC buckles 18 to prevent moisture from the upper part from entering the gap, and the excess part of the geothermal mat 15 is wrapped in the PVC buckles 18.

[0034] After the bedroom floor is completely dry (fine stone concrete layer 4), clean the floor and the corners, and check the flatness of the floor; after the construction conditions are met, lay the floor heating special mat on the ground and all sides should be higher than the wall surface. The mat interface needs to be overlapped and sealed with tape. When laying the floor, the cut should be coated with incision protection liquid to prevent moisture from penetrating. When laying to the connection with the wet ground (bathroom, kitchen, balcony), the mat should be turned up to cover the edge of the floor to prevent moisture from entering from the side.

[0035] The geothermal floor is attached to the ground through the geothermal floor cushion layer. The skirting is installed at one time and the excess floor cushion is cut off after the construction is completed.

[0036] The fine stone concrete layer 4 of the bathroom and bedroom floor construction structure is reserved for expansion joints 14. The setting of the expansion joint of the floor heating floor takes into account the floor area or side length. Generally, when it exceeds 30m² or the side length exceeds 6m, an expansion joint should be set, and the width of the expansion joint should not be less than 8mm. Here, the leveling thickness of the bedroom reaches 10-12 cm, so this embodiment sets two expansion joints on both sides of the length.

[0037] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
