Abstract

The invention belongs to a light, fireproof and low-heat-conducting-property integrated disassembly-free composite heat preservation formwork and a preparation process thereof. The light, fireproof and low-heat-conducting-property integrated disassembly-free composite heat preservation formwork comprises an inner protective layer connected with a concrete pouring wall, wherein a heat preservation material layer, an inorganic material protective layer and an outer anti-cracking layer are sequentially arranged outside the inner protective layer; the inner protective layer and the heat preservation material layer are connected in a reinforced mode through a mortise and tenon joint reinforcing structure, and the inorganic material protective layer and the outer anti-cracking layer are connected in a reinforced mode through a mortise and tenon joint reinforcing structure; and the outer anti-cracking layer, the inorganic material protective layer, the heat preservation material layer and the inner protective layer are fixedly connected with the concrete pouring wall through connecting anchor bolts. The light, fireproof and low-heat-conducting-property integrated disassembly-free composite heat preservation formwork has the advantages of being reasonable in structural design, small in heat conductivity coefficient, low in weight, convenient to construct and good in fireproof performance.

Description

technical field [0001] The invention belongs to the technical field of building energy-saving wall thermal insulation, and specifically relates to a light-weight, fire-resistant, low-thermal-conductivity integrated non-dismantling composite thermal insulation formwork and a preparation process thereof. Background technique [0002] my country is the largest construction country in the world. The huge construction scale causes the energy consumption of buildings in my country to account for more than one-third of the total energy consumption of the national economy. Therefore, there is a huge space for energy saving in buildings. Building energy saving is first of all the energy saving of its walls. The research and development, promotion and application of integrated building wall thermal insulation and energy saving technology products have become an effective solution to building energy saving, improving the quality of building energy saving and thermal insulation projects,...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the thermal insulation technology measures for the walls of newly-built buildings in my country adopt the traditional "rear-mounted external thermal insulation layer" method. These "external thermal insulation layer" technologies often have a long construction period, and the external thermal insulation wall is prone to cracking, falling off, and damage. People; organic insulation materials are easy to burn, and there are fatal defects such as public safety hazards; at the same time, the insulation layer is difficult to last the same life as the main body of the building; Disadvantages such as expensive decoration

[0004] In the prior art, inorganic lightweight slurry materials or inorganic cotton are compounded with organic thermal insulation materials, and the slurry is applied on both sides, and used as thermal insulation templates. The production process of this thermal insulation template is complicated, the production efficiency is low, and the thermal insulation and energy saving performance is poor. It takes 28 days for the cement to cure and solidify before leaving the factory, which leads to a long production cycle, occupies a large factory area, low industrialization level, high investment and production costs, and the externally applied mortar layer is thick in application, and there is a safety hazard of falling off under load; there are also grid panels The integrated thermal insulation technology adopts B1 or B2 grade as the thermal insulation material, and concrete with a thickness of not less than 5 cm must be poured on the outside as the protective layer of the thermal insulation material to meet the fire protection requirements. The 5 cm thick mortar has a self-weight of 125kg per square meter, which greatly increases The load of the project is increased, resulting in the increase of the steel and concrete content of the column base, the main beam column, etc., the construction period is long, the construction is difficult, and the cost is high

Application publication number CN104110082A discloses the integrated wall structure of cast-in-place concrete with built-in composite thermal insulation board in the external mold and its manufacturing method. The built-in composite thermal insulation boards all use organic thermal insulation materials, which cannot meet the requirements of the "Code for Fire Protection of Building Design" GB50016-2014 non-standard requirements, thus limiting its scope of use

In addition, the commonly used building formwork in the construction process of our country can only be used three or four times, and the best skilled workers can only use it six or seven times, resulting in huge waste of materials.
