Problems solved by technology

At present, the roofs of civil buildings have waterproof and thermal insulation measures. The surface layer is mostly made of fine stone concrete and separated. During the construction process, due to improper construction methods, the roof surface layer cracks seriously, resulting in serious maintenance burden and economic losses.

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] As shown in the figure, an anti-cracking construction process for a waterproof and thermal insulation roof surface layer of a building body slope roof structure includes the following steps:

[0025] 1. Insulation layer construction:

[0026] (1) Before paving, determine the position of the water dividing line, and find the slope according to the slope direction, and the slope faces the cornice or the cornice outlet.

[0027] (2) Use standard polymer mortar to fully glue the paving, the paving joints are staggered from each other, no error platform should appear between adjacent plates, and the joints of the plates are filled with mortar.

[0028] (3), the insulation layer must be equipped with vent holes and exhaust pipes according to requirements to avoid drumming of the coiled material.

[0029] (4), after the insulation board is ...

Abstract

The invention relates to the technical field of roof cracking prevention, in particular to an anti-cracking construction technology for the surface layer of a waterproof and thermal insulating roof ofa building slope top structure. The anti-cracking construction technology comprises steps of surveying and setting out; slope finding; insulation board laying and board joint grouting; mortar levelling; waterproof layer construction; setting out for dividing joints; embedding of the dividing joints; reinforcing mesh laying; concrete pouring; surface finishing; maintenance. Tensile stress caused by shrinkage and expansion of concrete due to temperature change, non-even sinking and the like can be resisted effectively, a good effect is realized in controlling concrete cracks, surface layer cracks of the roof are reduced greatly, hidden danger of leakage is reduced, maintenance cost is reduced, one-time construction qualification rate of the surface layer of the roof is increased, construction period is shortened, and the technology has remarkable economic benefit.

Description

technical field [0001] The invention relates to the technical field of roof crack prevention, in particular to a construction technique for crack prevention construction of a waterproof and thermal insulation roof surface layer of a building body slope roof structure. Background technique [0002] As a key part of project acceptance and creation of cups and awards, the roof has always been the top priority of engineering construction. In recent years, the cracking of the roof surface has attracted more and more attention. Improving the quality of the roof surface has become the key to creating high-quality projects. key items. At present, the roofs of civil buildings have waterproof and thermal insulation measures, and the surface layer is mostly made of fine stone concrete with separation measures. During the construction process, due to improper construction methods, the roof surface layer cracks seriously, causing serious maintenance burden and economic losses. In orde...
