FRP balcony thermal bridge cutoff structure and method

Abstract

The invention discloses an FRP balcony thermal bridge cutoff structure and method. The FRP balcony thermal bridge cutoff structure comprises a tension piece, a compression piece, a heat preservation material and a packaging piece and further comprises a shear-resistant piece, wherein the packaging piece is filled with the heat preservation material; the tension piece is made of FRP rib materials and located on the upper portion of the packaging piece, the two ends of the tension piece stretch out of the packaging piece, the end stretching out of the packaging piece is used for stretching intoa main floor slab, and the other end stretching out of the packaging piece is used for stretching into a balcony slab; and the compression piece is made of FRP rib materials and located on the lower portion of the packaging piece, one end of the compression piece stretches out of the packaging piece, and the end stretching out of the packaging piece is used for stretching into the balcony slab. According to the FRP balcony thermal bridge cutoff structure, the excellent mechanical property and thermal property of FRP are fully utilized, and the completeness of a load force transmission path isguaranteed while building thermal bridges are reduced. Manufacturing is easy and convenient, the stress property is good, the heat insulation property is excellent, the local heat transfer amount of the thermal bridges can be effectively reduced, the risk of structural moisture condensation and mildewing is reduced, and the living comfort of a house is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a novel FRP balcony thermal break bridge structure. Background technique [0002] With the prominence of global energy and ecological environment issues, people are paying more and more attention to the issue of building energy consumption. In response to this, some developed countries such as Europe and the United States first proposed the concept of "passive building" and put forward specific requirements for building energy conservation. Among them, reducing building thermal bridges is a key point in passive building design. Thermal bridge refers to the part where the heat flow is relatively dense when the building exchanges heat with the outside world. Since the heat transfer coefficient of some parts is significantly greater than that of other parts, the heat is transferred from these parts concentratedly, and finally the heat flow in these parts is relatively dens...

AI Technical Summary

Problems solved by technology

[0006] Scholars previously conducted research on thermal break bridges for balconies, and achieved certain technical achievements and applications, but they mostly focused on balcony slabs with a thickness of 200-350 mm. At this stage, the thickness of concrete floor slabs in my country generally ranges from 100 to 350 mm. 140mm, the slab thickness is thinner, and in the case of thinner slab thickness, the internal moment arm between the tension member and the compression member is smaller, which is more unfavorable for the control of the structural bearing capacity and deflection. The balcony thermal break bridge configuration cannot be directly applied to our country

Moreover, most of the current research on thermal breakable bridges for balconies is produced in Europe, and there is a lack of research in related fields in China. The research and development costs and cost of thermal breakable bridges are relatively high, and the quotations of existing products are also relatively high.
