Description

Technical Field

[0001] This invention relates to the field of floor insulation and moisture-proofing technology in cold regions, and particularly to a floor insulation and moisture-proofing structural board and its construction method. Background Technology

[0002] In cold regions, existing floor insulation and moisture-proofing typically employs partial insulation. The process involves first constructing a crushed stone grouting subbase. After the subbase is formed, insulation boards are installed on top of it, at a certain distance from the inner side of the exterior wall. Finally, a cast-in-place concrete slab is placed on top of the insulation boards and the uninsulated crushed stone grouting subbase. This construction method has limited insulation effectiveness and is relatively slow.

[0003] During construction, the lack of insulation board fixing and gap treatment between boards results in limited air tightness. When there is a large temperature difference between indoors and outdoors and a large indoor humidity, thermal bridging effect is likely to occur, leading to condensation, mold, or even water accumulation on the indoor floor and wall base, resulting in poor insulation performance.

[0004] Existing construction methods generally do not have a waterproof layer and use cast-in-place concrete slabs for moisture and water protection. In actual construction, if the concrete is not vibrated and compacted sufficiently, cracks and siphoning phenomena are likely to occur, resulting in indoor dampness and groundwater, causing damp floors, damp damage to furniture, and mold or peeling of wall decorations, resulting in poor moisture protection. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the background art, and to provide a floor insulation and moisture-proof structural board and a floor insulation and moisture-proof construction method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A type of floor insulation and moisture-proof structural panel includes a rectangular floor insulation and moisture-proof structural panel. The upper and lower surfaces of the floor insulation and moisture-proof structural panel are precast waterproof concrete panels and precast waterproof concrete base plates arranged horizontally opposite each other. Waterproof coating and foamed insulation material pouring ports are provided around the perimeter of the precast waterproof concrete panels. Waterproof concrete edge ribs are provided around the perimeter between the precast waterproof concrete panels and the precast waterproof concrete base plates. A support and reinforcement plate and an insulation plate are provided from top to bottom inside the space between the precast waterproof concrete panels and the precast waterproof concrete base plates. Support and reinforcement pins are inserted into the insulation plate, and the upper ends of the support and reinforcement pins are embedded in the support and reinforcement plate.

[0007] The insulation board has pre-drilled through holes, and the supporting and reinforcing pins are inserted into the through holes.

[0008] The supporting and reinforcing pins are made of PVC.

[0009] The supporting and reinforcing plate is a prefabricated PVC skin board or cement fiber board.

[0010] The precast waterproof concrete base slab and precast waterproof concrete panel protrude horizontally, while the waterproof concrete side ribs are recessed, forming an opening seam structure.

[0011] Beneficial technical effects of a floor insulation and moisture-proof structural panel: 1. The floor insulation and moisture-proof structural board of the present invention is surrounded by waterproof concrete: precast waterproof concrete base plate, waterproof concrete edge ribs and precast waterproof concrete panel, which has better strength and moisture and water resistance; the insulation board is wrapped inside, which has better waterproof, moisture-proof and fire protection, which can effectively avoid damage during construction and later use, and has better durability; at the same time, because the concrete protects the insulation board, the selection of insulation and fireproof materials is better.

[0012] 2. The internal support and reinforcement plates and support and reinforcement pins of the floor insulation and moisture-proof structural board of the present invention can effectively prevent the waterproof concrete panel from undergoing excessive bending deformation due to overload; at the same time, they protect the internal insulation board and prevent it from being compressed due to overload, resulting in better overall integrity, strength and durability.

[0013] 3. The floor insulation and moisture-proof structural board of the present invention is prefabricated as an integrated unit, consisting of insulation board, precast waterproof concrete base plate, waterproof concrete side ribs, and precast waterproof concrete panel. It is prefabricated in the factory, avoiding wet work on site, making it easier to control quality. The construction speed is faster than traditional construction processes, and the overall safety is better.

[0014] 4. The floor insulation and moisture-proof structural board of the present invention has an opening joint structure formed by a precast waterproof concrete base plate, a precast waterproof concrete panel and waterproof concrete edge ribs around its perimeter. At the same time, the waterproof and insulation materials filled in the joint interlock with each other, increasing air tightness and integrity, and making the insulation and moisture-proof capabilities better. Example

[0015] A construction method for a floor insulation and moisture-proof structural panel, the construction steps of which are as follows: First, the subgrade soil is compacted before the cast-in-place concrete subbase is constructed, and the surface is leveled and smoothed as it is poured. On the concrete subbase, waterproof membrane or waterproof coating is applied in two coats to create a two-way waterproof layer. On the waterproof membrane or coating, a floating layer of fine sand or low-grade mortar is constructed. A floor insulation and moisture-proof structural board is laid on the mortar floating layer, and the joints of the boards are made uniform with prefabricated plastic cross joint clips. Waterproof coating for the precast waterproof concrete base slab of the floor insulation and moisture-proof structural board is poured into the joints through the pouring ports for waterproof coating and foamed insulation material. Foamed insulation material for the board joints is poured into the joints of the waterproof concrete side ribs through the pouring ports for waterproof coating and foamed insulation material. During construction, the adjacent pouring ports for waterproof coating and foamed insulation material can also serve as vents to ensure full filling. Waterproof coating for the joints of the precast waterproof concrete panels is poured into the joints through the pouring ports for waterproof coating and foamed insulation material.

[0016] The above-mentioned floor insulation and moisture-proof structural slab is used for the construction of a decorative floor surface layer.

[0017] Beneficial technical effects of a construction method for a floor insulation and moisture-proof structural panel: 1. Excellent reinforcement performance: The cast-in-place concrete subfloor can improve the flatness of the floor insulation and moisture-proof structural slab, speed up the construction process, and is better at preventing uneven settlement and improving the overall strength and moisture-proof and insulation effect of the ground.

[0018] 2. Excellent moisture and water resistance: Waterproof membrane or waterproof coating is pasted on the concrete subfloor, forming two layers of waterproof layer in both directions, which improves the current situation of no waterproof layer on the construction ground. It also forms a double waterproof layer with the floor insulation and moisture-proof structural board, making the indoor ground moisture and water resistance better.

[0019] 3. Excellent protective performance: The fine sand or low-grade mortar floating layer reduces the impact load on the waterproof layer during the construction of the floor insulation and moisture-proof structural board, reduces damage to the waterproof layer, and provides better protection for waterproof membranes or waterproof coatings.

[0020] 4. Excellent quality control methods: The joints of the floor insulation and moisture-proof structural panels are made of prefabricated plastic cross joint clips to ensure uniform gaps, which facilitates the construction of waterproof coatings and foamed insulation materials in the later stage. This avoids gaps that are too small, resulting in incomplete filling of insulation and waterproof coatings, and better construction quality of moisture-proof and insulation materials in the panel joints.

[0021] 5. Excellent overall airtightness: The joints of the floor insulation and moisture-proof structural panels are filled with waterproof coatings for the bottom slab joints, foamed insulation materials for the board joints, and waterproof coatings for the panel joints on site. This makes the multiple insulation and moisture-proof floor panels tightly connected, with stronger overall integrity, improved joint insulation, airtightness, and waterproofness, avoids thermal bridging, and provides better waterproof, moisture-proof, and insulation performance of the floor.

[0022] Beneficial technical effects of the present invention: The connection between the floor insulation and moisture-proof structural board and the floor sub-layer of the present invention is tight, resulting in better moisture-proof and heat-insulating effects and faster construction speed.
