Particle diameter selecting pouring procedure of concrete aggregate for thermal insulation wall

Abstract

The present invention discloses a heat preserving wall concrete aggregate grain diameter selecting and pouring method, which comprises the following steps: a, preparing a concrete with separable aggregate grain diameters, wherein, the aggregate grain diameters of the concrete adopt subsection continue preparation, the pebble with grain diameter of 5 to 10 mm is 30 to 35% of the total amount of the pebble, and the pebble with grain diameter of 10 to 30 mm is 65 to 70% of the total amount of the pebble; b, conveying the concrete with separable aggregate grain diameter to a pouring working surface by a set of concrete conveying equipment, separating the concrete by using a concrete aggregate grain diameter selecting and separating device, conveying the concrete with small grain diameter aggregate to a shuttering with small thickness and pouring the concrete to a protection wall, and conveying the concrete with big grain diameter aggregate to a shuttering with large thickness and pouring the concrete to a shear wall, and the two pouring processes are carried out at the same time; c, vibrating the concrete at the two sides to guarantee that the concrete is compact. The invention has convenient construction, easy operation, low cost and excellent pouring effect, is suitable for the construction of the home building and office building in various forms in the town, and has good society and economic benefits.

Description

1. Technical field: [0001] The invention relates to a building construction method, in particular to a selective pouring method of concrete aggregate particle size for a thermal insulation wall. 2. Background technology: [0002] Exterior wall insulation technology is widely used in current construction projects, but because the insulation layer is placed outside the structural surface, and it is mostly connected to the wall by bonding, due to the influence of natural conditions such as wind and sun, the insulation layer cannot It has the same service life as the wall structure layer, and quality problems such as cracking and peeling of the outer surface of the building often occur within the design service life, which does not achieve a good thermal insulation effect and affects the appearance. [0003] In response to this situation, people have developed a built-in thermal insulation concrete structure (see figure 1 ), the built-in thermal insulation concrete structure pu...

AI Technical Summary

Problems solved by technology

Two kinds of concrete are poured on the same pouring surface at the same time, and the height difference between the two sides of the concrete is required to exceed 400mm (to prevent the insulation material from being squeezed and displaced), so two sets of concrete conveying equipment have to be used. In actual work, two sets of concrete conveying Equipment is difficult to coordinate and is difficult to achieve
