Building fully-prefabricated heat-preservation composite reinforced outer formwork and construction method thereof

Abstract

The invention provides a building full-prefabricated heat-preservation composite reinforced outer formwork and a construction method thereof, and belongs to the technical field of buildings. The formwork aims to solve the problems that an existing building heat-preservation formwork is low in precision, low in overall energy-saving efficiency and complex in construction. Cold-rolled thin steel is used as a framework, a cold-drawn steel wire mesh is integrally laid, a fireproof accessory is used as a fixing part, composite thermal insulation mortar with the thickness of 50 mm is poured, and a thermal insulation core material is further included. The fireproof accessory comprises a fixing part I-shaped connecting part, a fixing part II-shaped connecting part, a fixing part III-shaped connecting part and an L-shaped fixing steel clamp. A product is high in precision and strong in bending resistance, the construction precision is ensured, and the building assembly rate is improved; and the overall use scheme of the product can meet the national 75 energy-saving standard or above, the large-area leveling procedure is omitted, and the product is suitable for various building types and parts.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a fully prefabricated building thermal insulation composite reinforced external formwork and a construction method thereof. Background technique [0002] The whole country requires all industries to achieve carbon neutrality. In the construction industry, the construction of green buildings and passive houses is imperative, and building energy-saving technologies will be vigorously promoted. All localities require buildings to meet 75 energy-saving standards. In the external wall thermal insulation technology at home and abroad, most of them adopt thin plaster external wall external thermal insulation system, external wall thermal insulation and decoration integrated system fixed only by pasting and anchoring, and external wall smearing polystyrene particle thermal insulation mortar technology. Safety accidents such as falling off and catching fire have been banned in various p...

AI Technical Summary

Problems solved by technology

In the external wall thermal insulation technology at home and abroad, most of them adopt thin plaster external wall external thermal insulation system, external wall thermal insulation and decoration integrated system fixed only by pasting and anchoring, and external wall smearing polystyrene particle thermal insulation mortar technology. Safety accidents such as falling off and igniting, various policies have been issued to prohibit the use of the latter, the latter has the problem of insufficient energy saving efficiency and long-term falling off

Therefore, in recent years, the thermal insulation structure integration technology has emerged, and the thermal insulation board and the structure are constructed at the same time to achieve the purpose of the same life. At the same time, the construction process is relatively complicated, requiring large-scale leveling of the external wall and large-scale waterproofing of all holes. The construction quality is not high, and it is not suitable for other building parts and building types.
