Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, a construction method for cast-in-place of a infill wall and structure combination includes the following steps:
the method comprises the following steps: installing a light steel framework 4 and binding structural wall column 2 steel bars on a foundation or lower layer beam slab 1 by using bolts 6, placing a wall column partition plate 7 between the light steel framework 4 and the structural wall column 2 steel bars and close to one side of the light steel framework 4, connecting the light steel framework 4 and the structural wall column 2 steel bars by using the bolts 6, installing wall column templates 11 on two sides of a filling wall and the structural wall column 2, pouring structural concrete in a cavity of the structural wall column 2, pouring light concrete 5 in the cavity of the filling wall, and pressing and paving a wall beam partition plate 8 on the light concrete 5;
step two: after the lightweight concrete 5 is hardened, binding reinforcing steel bars of the structural beam 3 on the wall beam partition plate 8, connecting the lightweight steel framework 4 by using bolts, installing beam templates 12 on two sides of the structural beam 3, and then pouring the structural concrete;
step three: and after the wall column template 11 and the beam template 12 are dismantled, the glass fiber net anti-crack mortar protective layer 10 is integrally plastered on the surfaces of the structural wall column 2, the structural beam 3, the lightweight concrete 5, the wall column partition plate 7 and the wall beam partition plate 8.
The construction method is greatly improved in that the structural wall column reinforcing steel bars, the light steel framework 4, the wall column partition plates 7 and the connecting bolts 6 are synchronously installed, the concrete of the structural wall column 2 and the light concrete 5 share a set of templates for pouring, the wall beam partition plates 8 supported by the filling wall are used as the disassembly-free bottom molds of the structural beams 3, and the anti-crack mortar is synchronously plastered on the structural system and the filling wall, so that the organic combination and synchronous construction of the structural system and the filling wall are realized, the working procedures can be greatly simplified, the construction period can be shortened, the template consumables can be obviously reduced, and the construction cost can be reduced.
Preferably, the structural wall column 2 and the structural beam 3 form a reinforced concrete structural system, the light steel framework 4 and the light concrete 5 form a filler wall, the filler wall and the structural system are flexibly connected and elastically sealed, and the glass fiber net anti-crack mortar protective layer 10 is integrally adhered to the two side surfaces of the filler wall and the structural system.
The structure formed by the construction method meets the requirements of relevant specifications on the basic performances of structural stress, earthquake resistance, crack resistance, water tightness, air tightness and the like. Moreover, the filler wall of the invention can meet the requirement of 75% of energy conservation of buildings in various places when the thickness is 200-300mm, and the wall body is thinned by 50-100mm compared with the masonry external heat-insulation filler wall, thereby obviously improving the utilization rate of houses. The density of the wall surface to be filled is 80-120kg/m2The wall is only 25-50% of the masonry infilled wall, which is not only beneficial to improving the earthquake resistance of the building, but also can improve the earthquake resistance of the building through the cooperative designGreatly reducing the material configuration and the manufacturing cost of the building foundation and the main structure.
Preferably, the light steel framework 4 is formed by combining C-shaped or U-shaped thin-wall steel ribs in a ribbed mode, and is connected with the foundation or lower layer beam plate 1, the structural wall column 2 and the structural beam 3 through bolts 6, and the interval between the bolts 6 is not more than 1.2 m.

Preferably, the lightweight concrete 5 is polystyrene particle foam concrete or aggregate-free foam concrete, and the dry density is 200-.
The light concrete is adopted as the main material of the filler wall, sufficient heat preservation, sound insulation, fire prevention and compactness can be provided by a single material, the heat insulation bridge is cut off by wrapping the light steel framework 4, the fire resistance limit is improved, and other structures such as a wall heat preservation layer and the like do not need to be arranged independently. Moreover, the polystyrene particle foam concrete is foamed on site, processed and cast by pumping, the transportation volume of the material can be reduced by more than 50 percent, and the large-scale popularization and application are facilitated.
Preferably, the wall column partition plates 7 and the wall beam partition plates 8 are made of flame-retardant polystyrene boards, the thickness of the fire-retardant polystyrene boards is 20-40mm, and the width of the fire-retardant polystyrene boards is consistent with the thickness of the structural wall columns 2 and the structural beams 3.
The flame-retardant polystyrene board is used as an elastic partition board between the filling wall and the structural wall column 2 and the structural beam 3, good sealing effect can be realized by cast-in-place extrusion and tight bonding of two kinds of concrete, the deformation stress of the structure and the filling wall can be digested by the characteristics of the elastomer, and the problems of joint cracking, water permeation and air leakage are avoided.
Preferably, the structural heat-insulation plate 9 is arranged on one outdoor side of the structural wall column 2 and the structural beam 3 which need to be subjected to external heat insulation, and the structural heat-insulation plate 9 is installed on the steel bars of the structural wall column 2 or the structural beam 3 by using a tie piece before the structural concrete is poured and clamped in the wall column formwork 11 or the beam formwork 12.
The external heat-insulating layer of the structural system is synchronously finished during concrete pouring, so that the process of independently and externally sticking the heat-insulating plates is simplified, harmful gaps among the wallboards are eliminated, and favorable conditions are created for sharing a set of templates by the wall columns.
