Abstract
The invention relates to a cast-in-place light inner partition wall in the building material field and is characterized in that a lightweight insulation board (2) or a lightweight insulation board (2) and a hollow cylinder (3) are embedded in a wall body (1) which is manufactured by adopting a cast-in-place method. The cast-in-place method comprises the steps of: fixing a row of mold board at one side of the partition wall needing to be casted, later fixing the lightweight insulation board or the lightweight insulation board and the hollow cylinder in the middle of the partition wall needing to be casted, and then fixing another row of mold boards at the other side of the partition wall needing to be casted, wherein the terminals of the two rows of mold boards are connected with the existing wall body or an L-type component or a T-type component; casting inorganic cementitious slurry with self-leveling property between the two rows of mold boards, forming the cast-in-place lightweight inner partition wall by curing at normal temperature, and then dismantling the mold boards at the two sides of the partition wall. The cast-in-place lightweight inner partition wall is embedded with a lightweight insulation board, has more compact structure, no paving seams, better sound insulation effect and heat insulation effect, light wall body, simple construction and lower cost, and no need of prefabricated wall panel.
Description
Technical field:
The invention belongs to building material field, be specifically related to a kind of cast-in-place lightweight inner partition wall.
Background technology:
In existing technology, more internal partition wall adopts masonry to build by laying bricks or stones and forms, and the metope of building by laying bricks or stones is rough and uneven in surface, need spread one deck mortar levelling, complicated operation on metope again; And the surface density of body of wall is bigger, has increased load of buildings, makes building costs directly rise, and masonry easily causes metope cracking, influences result of use.As existing gypsum block and gypsum lath exist complex manufacturing technology, difficulty of construction big, need that a large amount of accumulation place, cost of transportation are too high, the large-scale production investment is excessive in producing, the shortcoming etc. of structural stability difference after the moulding.No. 200610046968.3 patent applications of China provide a kind of scheme of cast-in-place light partition wall, but this scheme still needs the dry wall panel, and not only complex process, and sound-insulating and heat-insulating effect is not fine yet.
Summary of the invention:
The objective of the invention is can not satisfy the weakness that the heavy construction group uses because of production scale is too small in order to overcome existing batten and building block, for people provide a kind of technology simple, the cast-in-place lightweight inner partition wall that sound-insulating and heat-insulating is effective.
The objective of the invention is to realize by following technical proposals.
Cast-in-place lightweight inner partition wall of the present invention is characterized in that adopting in the body of wall that cast-in-place method makes, and is inlaid with light heat-insulating plate or light heat-insulating plate and hollow cylindrical shell.
In the such scheme, described body of wall is cement based body of wall or gypsum base body of wall or cement/plaster combined wall.
In the such scheme, described light heat-insulating plate is polystyrene foam plate, lightweight concrete slab, light gypsum board, light compound material board or lightweight electromagnetic wave shielding plate.
In the such scheme, described hollow cylindrical shell is the hollow plastic barrel of hollow paper web, water permeability or impermeability, hollow thick bamboo tube or other water permeabilitys or impermeability light material hollow cylinder.
In the such scheme, before the body of wall drying, described body of wall bottom offers the ventilation dewetting hole, and the ventilation dewetting hole is communicated with hollow cylindrical shell, plays the hydrofuge effect by the natural air exhaust mode.
In the such scheme, described cast-in-place method is: the side at the partition wall of need cast is fixed row's template, then at partition wall center fixed light heat-insulating plate or the light heat-insulating plate and the hollow cylindrical shell of need cast, and then fix one at the partition wall opposite side of need cast and arrange template, terminal and the existing body of wall of two row's templates or L type member or T type member link to each other, cast has the inorganic gel slurry of self-leveling energy in the middle of two row's templates, normal temperature cure is laid down the template of partition wall both sides after forming the cast-in-place lightweight inner partition wall body of wall again.
In the such scheme, the both sides of described light heat-insulating plate or light heat-insulating plate and hollow cylindrical shell are provided with the wall thickness control member.
In the such scheme, in the middle of the described template, be provided with the thickness of wall body control member.
In the such scheme, described inorganic gel slurry with self-leveling energy can be cement based slurry or gypsum base slurry or cement/plaster composite mortar.
The present invention is that the inventor passes through long-felt, repeatedly practises the technical scheme of summing up the science practicality of coming out, compared with prior art, cast-in-place lightweight inner partition wall of the present invention, structure is tightr, does not have puzzle joint, its intensity and soundproof effect are better, be inlaid with light heat-insulating plate or light heat-insulating plate and hollow cylindrical shell in body of wall, make sound-insulating and heat-insulating effective, body of wall is light, do not need the dry wall panel, need not extract hollow cylindrical shell out, construction is simple, and cost lowers.
As gypsum material embodiment of the present invention, overcome gypsum block and gypsum lath complex manufacturing technology, difficulty of construction big, need that a large amount of accumulation place, cost of transportation are too high, the large-scale production investment is excessive in producing, the shortcoming of structural stability difference after the moulding.Simultaneously, airtight because of it is the integral wall of moulding by casting at the construction field (site), improved the sound insulation property of body of wall widely.The coefficient of thermal conductivity of body of wall is lower than 0.3[w/ (m.k) generally speaking], only the body of wall of 12cm thickness just can satisfy the requirement of Xia Redong cryogenic region party wall thermal transmittance, and its thermal transmittance of the body of wall of 9cm thickness can satisfy the requirement of the lower bound thermal resistance at " cold and hot bridge " position under the insulation situation in the Xia Redong cryogenic region.
