Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a floor deformation joint structure of a steel structure and a concrete structure of an indoor ski resort. Background Art

[0002] Indoor ski resorts are generally buildings with extra-long plane dimensions. In order to avoid irreversible damage to the structure caused by uneven foundation settlement and temperature expansion stress, structural designers usually set expansion joints to disconnect the extra-long structure.

[0003] The traditional ski slope structure is a unified reinforced concrete floor. The linear expansion coefficients of the materials on both sides of the deformation joint are almost the same, and they change synchronously due to the temperature effect. Accordingly, the deformation joints are mostly sealed by filling the middle of the deformation joint with flexible materials, and the steel plate is fixed on the floor surface to bear the load. With people's pursuit of skiing experience, the ski slopes are designed to be longer and longer, and the height difference is getting bigger and bigger. The highest point of the ski slope can reach about 100 meters. In order to shorten the construction period, the high area of ​​the ski slope generally adopts steel structure, the ski slope structural surface adopts steel structure floor slab, and the low area adopts frame structure reinforced concrete floor. The waterproof insulation at the deformation joint is originally a weak point. In addition, the two ends of the deformation joint are different structures, the linear expansion coefficients are different, and the stress deformation is inconsistent, which leads to the frequent cracking of the insulation and waterproof materials at the deformation joint. Then the heat from the lower warm area is transmitted to the upper cold area, causing the snow layer to melt. The melted snow water invades the insulation layer of the deformation joint, reducing the insulation performance, causing a vicious cycle, seriously affecting the experience of tourists and increasing safety hazards.

[0004] Therefore, how to design a deformation joint structure that can adapt to the inconsistency of deformation between different structures and have good thermal insulation and waterproof functions is the key to solving the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a floor deformation joint structure of the steel structure and the concrete structure of an indoor ski resort, which reduces the easy melting snow leakage in the deformation joints between different structures, increases the service life of the sealing structure, and optimizes the skiing experience.

[0006] To achieve the above-mentioned purpose, the utility model provides a floor deformation joint structure of the steel structure and the concrete structure of an indoor ski resort, comprising a supporting structure fixed between a steel structure floor slab and a reinforced concrete structure floor slab, an insulation layer located above the supporting structure, a waterproof layer located above the insulation layer, a drainage structure located above the waterproof layer, and a load-bearing structure located above the drainage structure and used to bear a snow layer; the drainage structure is a water collecting trough steel plate embedded in the middle of the concrete of the refrigerant layer on both sides of the deformation joint, the middle part of the water collecting trough steel plate is concave to form a drainage trough for draining melted snow water from the snow layer above; the cavity between the water collecting trough steel plate and the waterproof layer is filled with rubber-plastic sponge; the load-bearing structure is a load-bearing steel plate, and the cavities of the water collecting trough steel plate and the load-bearing steel plate are poured with non-solidified asphalt.

[0007] Preferably, the water collecting trough steel plate extends to both sides of the outer wall in the same direction as the deformation joint, and a drainage ditch is provided on the outer wall side of the ski resort. When it reaches the outer wall end, the concave part of the water collecting trough steel plate is connected to a rainwater gutter to drain the snow water to the drainage ditch through a vertical drainage pipe.

[0008] Furthermore, the supporting structure is a U-shaped stainless steel plate, the straight section at the top of the U-shaped stainless steel plate is fitted with the upper surface of the steel structure floor slab and the reinforced concrete structure floor slab, and is fixed with expansion bolts, and the height of the U-shaped stainless steel plate is consistent with the thickness of the reinforced concrete structure floor slab.

[0009] Preferably, the U-shaped stainless steel plate is filled with glass wool, and the glass wool is filled to the lower surface of the thermal insulation layer.

[0010] Furthermore, the waterproof layer is a waterproof coiled material, and the waterproof coiled material is concave in the middle of the deformation joint, leaving a margin for expansion and contraction.

[0011] Furthermore, the upper surface of the load-bearing steel plate is arranged flush with the floor surfaces on both sides, and the contact surface between the load-bearing steel plate and the cold coal layer is fully adhered with butyl waterproof tape.

[0012] Preferably, the two sides of the deformation joint are, from bottom to top, a structural layer, a first leveling layer, a vapor barrier layer, a thermal insulation layer, a second leveling layer, a waterproof layer, a protective layer, a refrigerant layer and a snow layer.

[0013] Preferably, the thermal insulation layer is an extruded polystyrene board of 200 mm thickness, two layers are spliced ​​with staggered seams and bonded with a two-component polyurethane adhesive, and the seams between adjacent extruded polystyrene boards of the same layer are filled with a flexible rubber-plastic sponge.

[0014] From the above, compared with the prior art, the floor deformation joint structure of the indoor ski resort steel structure and concrete structure of the utility model has at least the following beneficial effects:

[0015] 1. The load-bearing steel plate is flush with the concrete surface of the refrigerant layer, which reduces the resistance of the snowplow walking on it, reduces the loss of the load-bearing steel plate, and increases the service life.

[0016] 2. Compared with the traditional snow track floor deformation joint structure, the drainage function of melted snow water is added. The middle part of the water collecting trough steel plate is concave similar to a drainage trough. There are generally wall drainage ditches on both sides of the snow track near the outer wall. The melted snow water is collected at the end through the water collecting trough. A drainage riser is installed at the end to drain the water to the wall drainage ditch to prevent snow water from invading the insulation layer and reducing the insulation effect.

[0017] 3. The waterproof material at the bottom of the load-bearing steel plate is non-solidified asphalt. Compared with traditional rubber waterstop, non-solidified asphalt has better ductility and plasticity, and can better adapt to the uneven expansion and contraction changes in different structures.

[0018] 4. The lower side of the expansion joint is supported by a U-shaped stainless steel plate. The outer surface of the U-shaped stainless steel plate is sprayed with fire-retardant paint, and the inside of the U-shaped stainless steel plate is filled with glass wool with excellent fire-retardant performance. Compared with the traditional expansion joint structure, redundant facilities such as fire-blocking belts and vapor barrier membranes are eliminated, making construction more convenient.

[0019] 5. Convenient construction. Construction workers can complete all the construction contents of blocking on the upper part of the floor surface without having to work on the lower part, which reduces the safety risks of high-altitude operations, saves the cost of safety measures, and improves construction efficiency.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See below Figure 1 to Figure 4 The floor deformation joint structure of the steel structure and concrete structure of the indoor ski resort of the utility model is described in detail.

[0028] The floor deformation joint structure of the steel structure and concrete structure of the indoor ski resort of the utility model includes a supporting structure fixed between the steel structure floor slab 9 and the reinforced concrete structure floor slab 8, an insulation layer 15 located above the supporting structure, a waterproof layer 17 located above the insulation layer 15, a drainage structure located above the waterproof layer 17, and a load-bearing structure located above the drainage structure and used to bear the snow layer 20.

[0029] The drainage structure is a water collecting tank steel plate 4 embedded in the middle of the concrete of the refrigerant layer on both sides of the deformation joint. The water collecting tank steel plate 4 is made of stainless steel, and the middle part is concave to form a drainage groove to drain the melted snow water of the snow layer above. The cavity between the water collecting tank steel plate 4 and the waterproof layer 17 is filled with rubber-plastic sponge 5. The waterproof layer 17 adopts a 4mm thick modified waterproof roll specially used for bridges. The waterproof roll is concave in the middle of the deformation joint, leaving a margin for expansion and contraction.

[0030] The load-bearing structure is a load-bearing steel plate 1, which is a 12mm thick stainless steel plate. The upper surface of the load-bearing steel plate 1 is flush with the floor surfaces on both sides and does not rise. The contact surface between the load-bearing steel plate 1 and the cold coal layer 19 is fully adhered with butyl waterproof tape 11. The cavity between the water collection tank steel plate 4 and the load-bearing steel plate 1 is poured with non-solidified asphalt 3, and the non-solidified asphalt 3 is poured until it is flush with the upper surface of the concrete of the cold medium layer 19.

[0031] The supporting structure is a 3mm thick U-shaped stainless steel plate 7, which has the same fire resistance as the structural floor slab and is used to support the deformation joint structure on the upper part. The straight section on the top of the U-shaped stainless steel plate 7 fits the upper surface of the steel structure floor slab 9 and the reinforced concrete structure floor slab 8 and is fixed with expansion bolts 2. The height of the U-shaped stainless steel plate 7 is consistent with the thickness of the reinforced concrete structure floor slab 8.

[0032] The U-shaped stainless steel plate 7 is filled with glass wool 6, with high-strength moisture-proof veneer on both sides, and the glass wool 6 is filled to the lower surface of the insulation layer 15. The glass wool 6 has excellent insulation and fireproof properties, and increases the insulation performance of the deformation joint.

[0033] The floor ski slope (both sides of the deformation joint) of the utility model is constructed from bottom to top as follows: a structural layer 12 (in this example, the left side of the deformation joint is a steel structure floor slab 9, and the right side of the deformation joint is a reinforced concrete structure floor slab 8), a leveling layer 13 (20mm thick 1:3 cement mortar), a vapor barrier 14 (using 1.5mm type II single-component polyurethane waterproof coating), an insulation layer 15 (200mm thick extruded polystyrene board, two layers of staggered joints, bonded with a two-component polyurethane adhesive, and the same The gaps between adjacent extruded polystyrene boards are filled with flexible rubber-plastic sponge 5), the second leveling layer 16 (40mm thick fine stone concrete, with Φ4@200 steel mesh inside, 3m×3m cut and divided into seams, and the seams are filled with weather-resistant sealant), a waterproof layer 17 (4mm thick modified asphalt waterproof membrane specially used for bridges and sanded on both sides), a protective layer 18 (20mm thick 1:3 cement mortar), a refrigerant layer 19 (120mm thick C30 frost-resistant concrete), and a 400mm thick snow layer 20.

[0034] The floor deformation joint between the steel structure and the concrete structure of the indoor ski resort of the present invention is constructed between the reinforced concrete structure floor slab 8 and the steel structure floor slab 9, which is constructed from bottom to top. The steel structure floor slab 9 is supported by an I-beam 10.

[0035] like Figure 1As shown, the utility model first installs a U-shaped stainless steel plate 7 between the deformation joints to support the upper insulation and waterproof structure. The straight part of the concave part of the U-shaped stainless steel plate 7 is flush with the side surface of the reinforced concrete structure floor 8 and the steel structure floor slab 9. The bottom end of the U-shaped stainless steel plate 7 is a curved concave shape with enough expansion margin to prevent uneven expansion and contraction changes from damaging the supporting steel plate. The U-shaped stainless steel plate 7 is fixed to the steel structure floor slab 9 and the reinforced concrete structure floor slab 8 with M12 expansion bolts 2, and the close-fitting parts of the reinforced concrete structure floor slab 8 and the steel structure floor slab 9 are fully adhered with butyl waterproof tape 11 to prevent the lower water vapor from invading the deformation joint. The lower surface of the U-shaped stainless steel plate 7 is sprayed with fire retardant paint, and the fire resistance limit after treatment is the same as that of the structural floor slab.

[0036] In addition, the interior of the U-shaped stainless steel plate 7 is filled with glass wool 6, which has excellent heat preservation, heat insulation and waterproof properties. A high-strength moisture-proof veneer is used between the contact surface of the glass wool 6 and the U-shaped stainless steel plate 7 to ensure that the glass wool 6 does not sag and improve the heat preservation performance of the deformation joint.

[0037] The upper part of the glass wool 6 is the extruded polystyrene board of the insulation layer 15. The insulation board at the deformation joint and the extruded polystyrene boards on both sides of the deformation joint are laid at the same time. The overlap seams of the two layers of extruded polystyrene boards are staggered. The adjacent extruded polystyrene boards of the same layer are filled with flexible rubber and plastic sponge 5 to adapt to the expansion and contraction changes at the deformation joint. The lower plate and the lower structure, the upper plate and the lower plate are bonded with a two-component polyurethane adhesive to ensure that the extruded polystyrene board is flat and does not bulge.

[0038] After the insulation layer 15 is constructed, the second leveling layer 16 is constructed. The second leveling layer 16 is in a basin shape with high sides and low in the middle at the deformation joint, and the lowest point in the middle is the surface of the extruded polystyrene board. The second leveling layer 16 is above the waterproof layer 17. The waterproof membrane of the waterproof layer 17 at the deformation joint is concave at the deformation joint, leaving a stretch margin to prevent uneven expansion and contraction changes from tearing the waterproof membrane.

[0039] After the waterproof layer 17 is constructed, the rubber and plastic sponge 5 is filled on the top to half the height of the refrigerant layer 19. When pouring the concrete of the refrigerant layer on both sides of the deformation joint, the water collecting trough steel plate 4 is pre-buried at the middle height position of the concrete of the refrigerant layer. The middle of the water collecting trough steel plate 4 is concave to form a drainage trough to drain the melted snow water of the upper snow layer. The water collecting trough steel plate 4 extends to both sides of the outer wall in the same direction as the floor deformation joint. The ski resort is provided with a drainage ditch on the side close to the outer wall. When it reaches the outer wall port, the concave part of the water collecting trough steel plate 4 is connected to the rain bucket, and the snow water is drained to the drainage ditch by a vertical drainage pipe. The middle part of the water collecting trough steel plate 4 is designed to be concave and also leaves a telescopic margin to prevent the telescopic deformation of the steel plate. With the long-term use of the ski resort, the upper snow layer 20 will inevitably melt. This structure has a good drainage effect on the upper melted snow water, preventing water vapor from invading the lower insulation layer 15 and destroying the insulation effect of the warm zone.

[0040] The non-solidified asphalt 3 is poured into the cavity of the water collecting trough steel plate 4 and the load-bearing steel plate 1. The non-solidified asphalt 3 is a flexible waterproof material, which can adapt to the expansion and contraction changes at the deformation joint and has good waterproof and weather resistance, thereby enhancing the waterproof effect here.

[0041] When pouring the concrete of the refrigerant layer 19 on both sides of the expansion joint, a tongue and groove is reserved on the upper part of each side of the expansion joint extending 300mm, and the height of the tongue and groove is just the thickness of the load-bearing steel plate 1. After the concrete of the refrigerant layer reaches a certain strength, the load-bearing steel plate 1 is installed and fixed with M12 expansion bolts 2. After installation, the upper surface of the load-bearing steel plate 1 is just flush with the upper surface of the refrigerant layer 19. This structure changes the defect that the steel plate of the traditional floor expansion joint is located on the upper part of the refrigerant layer, ensures the convenience and safety of the snowplow walking on it, and increases the service life of the expansion joint. The concrete overlap between the load-bearing steel plate 1 and the refrigerant layer 19 is fully adhered with butyl waterproof tape 11 to prevent water vapor from invading.

[0042] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
