Description
Technical Field
The invention belongs to the technical field of building construction, in particular to a casting mould system of a cast-in-place concrete sandwich partition wall with an extrusion molding heat insulation plate and a construction method for casting.
Background
In high-rise buildings, the cast-in-place concrete sandwich partition wall (outer wall) not only can meet the heat insulation performance of the building partition wall, but also can meet the requirements of no plastering even due to the fact that the wall body, floor beam plates and wall columns are simultaneously supported by a formwork and simultaneously poured and molded at one time, and the wall body performance is excellent in overall performance, high in dampproof and seepage-proof performance and good in appearance flatness and appearance quality compared with a block wall; in the construction process, the cast-in-place concrete sandwich partition wall (outer wall) is adopted, so that the usage amount and the construction time of building blocks and mortar are greatly reduced, the loss amount of the building blocks and the mortar is greatly reduced, and the construction period is shortened. Therefore, in high-rise buildings, cast-in-place concrete sandwich partition walls (outer walls) are widely used.
The heat preservation function of the cast-in-place concrete sandwich partition wall (outer wall) is realized by an extruded polystyrene foam board (hereinafter referred to as an extruded board) in the middle of the wall, and an anti-cracking reinforcing steel bar net is arranged on the outer side of the wall to prevent the cracking of the concrete wall; in the construction process, how to ensure that the extruded sheet in the middle of the wall body is not impacted and displaced by concrete and even broken in the wall body when the concrete is poured is a key for guaranteeing the quality of the cast-in-place concrete sandwich partition wall (outer wall).
The existing method is that iron wires penetrate through an extruded sheet, fine stone concrete blocks (strips) are bound on two sides of the extruded sheet, and the outer anti-cracking steel bars are propped against, so that the extruded sheet is fixed in the middle of a wall body; in addition, other plastic or metal fixing pieces penetrating through the extruded sheet are adopted to fix the extruded sheet on the anti-cracking reinforcing steel bars, and the fixing mode is common at present. But the following problems are prevalent:
1. the fixed mode in the past is used and needs to pass the extruded sheet, because damaged the extruded sheet, causes extruded sheet intensity, rigidity to descend, when concrete placement, the extruded sheet is fragile.
2. Fine stone concrete blocks (strips) or fixing pieces bound on the middle part and the upper part of the extruded sheet are carried by the strength of the extruded sheet; when concrete is poured, fine stone concrete blocks (strips) or fixing pieces at the middle part and the upper part block the concrete from falling, and the falling pressure of the concrete is transmitted to the extruded sheet; the extruded sheet is distorted, crushed and crushed due to insufficient strength; the extruded sheet is misplaced, cracked and unevenly distributed in the wall body, so that the wall body loses heat preservation performance; meanwhile, due to dislocation of the extruded sheet and uneven fragment distribution, the thickness of the wallboard concrete is irregular and inconsistent, and thus the quality problems of wall cracking and the like often occur.
3. Because extruded sheets are easy to distort, fracture and crack, more fixing parts are often used for reinforcing and fixing the extruded sheets to ensure quality, and the fixing parts cannot be taken out after being embedded into concrete, so that the consumption is large and the material saving is not facilitated.
Therefore, innovatively improving the extruded insulation board fixing device of the cast-in-place concrete sandwich partition wall (outer wall) is necessary.
