Embodiment Construction

[0043] A kind of thermal insulation system of cast-in-place concrete without demolition compound formwork, refer to figure 1 and figure 2 , which includes double rows of light steel keels 1, double rows of light steel keels 1 are fixed on both sides of the steel beam as the wall skeleton, double rows of light steel keels 1 are connected by braces 2, two light steel keels 1 A supporting block 5 is arranged between them, and both ends of the bottom wall of the supporting block 5 are provided with limiting grooves 51, and the limiting grooves 51 are engaged with two corresponding light steel keels 1 on the same horizontal plane. There are multiple support blocks 5 distributed in a rectangular array. The thermal insulation formwork 3 is fixed on the outer side of the light steel keel 1 by the connecting member 4 to form the thermal insulation decorative surface of the outer wall, and the filler 6 is poured between the thermal insulation templates 3, and foamed polyurethane is us...

Abstract

The invention discloses a cast-in-place concrete non-dismantling composite formwork heat insulation system and a construction process thereof, and relates to the technical field of heat insulation ofbuildings, aiming at solving the problem of water leakage hidden in the joint part of a traditional outer wall retaining body method of a steel structure building. According to the technical scheme, the system comprises double rows of light steel keels and two layers of heat insulation formworks, wherein connecting members are arranged on the heat insulation formworks, supporting blocks are arranged between the two light steel keels, two limiting slots matching the corresponding light steel keels in a clamping manner are arranged at two ends of the bottom walls of the supporting blocks close to the corresponding light steel keels, and a filling material is poured between the two heat insulation formworks; and each heat insulation formwork comprises an inner bonding reinforcing layer, a graphite extruded plate, a mortar interface layer, a heat insulation transition layer and an outer bonding reinforcement layer which are sequentially arranged along the thickness direction, and a polyurethane foam for sealing gaps is arranged between the heat insulation formworks. The cast-in-place concrete non-dismantling composite formwork heat insulation system and the construction process thereofachieve the effect of solving the problem of water leakage hidden in the joint part of the traditional outer wall retaining body method of the steel structure building.

Description

technical field [0001] The invention relates to the technical field of building heat preservation, in particular to a heat preservation system of cast-in-place concrete without dismantling composite formwork and a construction process thereof. Background technique [0002] PC components (concrete sandwich wall panels) are prefabricated in the factory and hoisted on site. The concrete wall panels are fixed with steel beams using steel corner brackets. After the components are hoisted, the interior and exterior finishes will be constructed. [0003] The above method has the following problems: the wall panel is fixed by using steel corner brackets to suspend and fix the PC components. In order to avoid excessive manufacturing deviation of the PC components produced by the factory, a width of 20 mm is deliberately reserved between components and beams and columns, and between components. The seam is used as a component deviation adjustment space, and the cement mortar material ...
