Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model provides an assembled wall body of built-in cast in situ concrete outer wall in composite rock wool board vat, it includes by outer prefabricated heat preservation board 1, the body of casting 2 and the template 3 that sets gradually in to, prefabricated heat preservation board 1 and template 3 are located the both sides of the body of casting 2 respectively. The form of forming the casting body 2 through the cast-in-place links together heated board 1 and template 3, owing to saved the step of pasting the heated board to the concrete outer wall among the prior art, consequently makes construction process simpler, can also greatly reduced cost, and per square meter can save the expense of about 50 yuan.
Further, still be provided with connecting piece 4 on prefabricated heated board 1, the one end of connecting piece 4 stretches into in the body of casting 2 to make prefabricated heated board 1 more firm with the body of casting 2 combination.
In one embodiment, the connecting member 4 is a screw, as shown in fig. 2, the length of the connecting member 4 is 40-60cm longer than the thickness of the prefabricated heat-insulation board 1, that is, the connecting member 4 penetrates through the prefabricated heat-insulation board in the thickness direction and extends out of the prefabricated heat-insulation board 1 by about 40-60cm, after the casting body 2 is formed, one part of the connecting member 4 is in the prefabricated heat-insulation board 1, and the other part is in the casting body 2, so that the firmness of the combination of the prefabricated heat-insulation board 1 and the casting body 2 can be improved.
In one embodiment, as shown in fig. 3, 6-10 mounting holes 11 are formed on the prefabricated heat-insulation board 1, and the connecting member 4 is disposed in the mounting hole 11. Preferably, the mounting holes 11 are symmetrically arranged about the center of the prefabricated heat-insulating board 1.
In one embodiment, the prefabricated insulation board 1 is a composite rock wool board. Specifically, prefabricated heated board 1 is vertical silk composite rock wool board. The composite rock wool board has high strength, so that the strength of the outer wall is improved; and the composite rock wool board has no stimulation to the human body, and can avoid causing injury to constructors.
In one embodiment, the prefabricated insulation panels 1 are 120cm, 60cm and 10cm in length, width and thickness, respectively. In addition, prefabricated heated board 1 is still according to the various dysmorphism composite rock wool boards of design drawing preparation.
In one embodiment, the form 3 is a knock-out form, for example, the form 3 is a knock-out bamboo veneer. Since the bamboo plywood is damaged when the concrete is poured, the removable form needs to be removed after the cast body 2 is formed.
Furthermore, after the template 3 is removed, a leveling layer is arranged on the inner side of the pouring body 2. Wherein the thickness of the leveling layer is 5-20 cm. The leveling layer 5 is a rubber powder polyphenyl particle leveling layer.
In one embodiment, the form 3 is a demolition-free wood wool cement board. Because the strength and the toughness of the wood-wool cement board are superior to the performance of the removable templates such as the bamboo plywood and the like, the removal-free template does not need to be removed after the pouring body 2 is formed.
In one embodiment, the inside of the formwork 3 and/or the outside of the prefabricated heat-insulating board 1 is provided with a finishing layer. So as to improve the integral aesthetic effect of the building and unify the design style of the building group. Wherein, the material of the veneer layer 14 should meet the requirements of the building industry standard of 'glue powder polyphenyl granule exterior wall external thermal insulation system' (JG 158).
In one embodiment, the casting 2 is an organic light mortar or an inorganic light mortar. Wherein, the organic light mortar is provided with polyphenyl particles; the inorganic light mortar is provided with vermiculite particles, perlite particles, waste rock cotton residues or wheat straws.
In addition, the organic light mortar or the inorganic light mortar can be poured on the construction site by adopting cement or gypsum.
In one embodiment, the wood-wool cement board is composed of wood wool and cement, a plurality of wood wool in straight line sections are arranged in the wood-wool cement board, the plurality of wood wool mutually enclose a non-through mesh, and the plane figure of the mesh is triangular, quadrilateral or polygonal. The length of the wood wire is 60-300mm, the wood wire is kept in a straight line section state and cannot form a coil (twist) shape, and the rigidity of each wood wire can be fully displayed. Because all wood filaments are straight (theoretical concept, a small amount of wood filaments are slightly arc-shaped when actually paved, but the side forming meshes is also a straight line section side), a plane figure of the non-through meshes formed by the straight line section wood filaments in the vertical and horizontal staggered mode is necessarily triangular, quadrangular and polygonal, and from the three-dimensional concept, the triangular, quadrangular and polygonal are cooperatively built up in the vertical and horizontal staggered mode to form a frame type mesh structure, so that the overall strength of the mesh structure is higher.
As shown in fig. 4, the construction process of the assembled wall according to the present invention will be described in detail.
Firstly, the prefabricated heat-insulation board 1 with the connecting piece 4 is fixed with the steel bars of the building in a bundling mode.
Secondly, the formworks 3 are arranged on the inner sides of the prefabricated heat-insulation boards 1, and a concrete pouring cavity is formed between the prefabricated heat-insulation boards 1 and the formworks 3.
Thirdly, concrete is poured in the cavity, a casting body 2 is formed after the concrete is solidified, and one end of the connecting member 4 is cured in the casting body 2.
Fourthly, the formwork 3 is removed and the inside of the casting body 2 is coated with glue powder polyphenyl granules for leveling (if a non-removable formwork is used, this step can be omitted).
Finally, a finishing coat is arranged on the inner side of the template 3 and/or the outer side of the prefabricated heat-insulation board 1.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict.
