Special tool for foam concrete sandwich compound insulation building block subjected to post foaming forming

Abstract

The invention discloses a special tool for a foam concrete sandwich compound insulation building block subjected to post foaming forming. The special tool is characterized by comprising U-shaped outer blocking supporting plates 1, U-shaped inner blocking supporting plates 5 and connecting rods 6, wherein each U-shaped outer blocking supporting plate 1 is provided with a plurality of vertical grooves 3 and a plurality of vertical supporting plates 2 as well as connecting posts 4; each U-shaped inner blocking supporting plate 5 is provided with a plurality of vertical supporting plates 2 as well as connecting posts 4; each connecting rod 6 is provided with strip-shaped connection ports 7; each U-shaped outer blocking supporting plate 1 provided with the plurality of the vertical grooves 3 and the plurality of the vertical supporting plates 2 as well as the connecting posts 4 and each U-shaped inner blocking supporting plate 5 provided with the plurality of vertical supporting plates 2 as well as the connecting posts 4 are symmetrically arranged at two ends of each prefabricated concrete outer block body 8 and two ends of each prefabricated concrete inner block body 9; the connecting rods 6 are buckled onto the connecting posts 4, so that the U-shaped outer blocking supporting plates 1 and the U-shaped inner blocking supporting plate 5 are closely connected with the outer block bodies 8 and the inner block bodies 9; the tool and a supporting plate 11 form a die cavity 10 with a sealed bottom and a sealed periphery, and the die cavity is used for pouring foamed concrete liquid slurry 14, and a foam concrete insulation fire-proof plate 12 is manufactured.

Description

technical field [0001] The invention relates to a post-foaming molding foam concrete sandwich composite thermal insulation block special tooling, specifically a kind of prefabricated solid concrete outer leaf block 8 and inner leaf block on the sandwich composite thermal insulation block production line Body 9 is molded with the prepared foam concrete liquid slurry at one time to produce a special tooling for post-foaming foam concrete sandwich composite thermal insulation fireproof blocks. Background technique [0002] In order to achieve sustainable development, the country enforces the energy-saving building, which has increased energy-saving from 50% to 65%. Ordinary concrete blocks can no longer meet the energy-saving requirement of 65%.

Problems solved by technology

[0002] In order to achieve sustainable development, the state enforces energy-saving buildings, which have increased energy-saving from 50% to 65%. Ordinary concrete blocks can no longer meet the energy-saving requirements of 65%.

The existing polystyrene board thin plaster exterior wall insulation system has many problems: (1) the external insulation layer of the exterior wall is cracked; (2) the external insulation layer falls off; (3) the insulation layer has poor impact resistance; (4) the insulation layer Materials and buildings have different life spans; (5) prone to major fires, etc.

Basically, it is a sandwich composite insulation block composed of concrete perforated block 1, concrete surface layer block 3 and polystyrene insulation board 2. Although the cold bridge formed by concrete ribs, walls and bottom is cancelled, there are still fatal The technical defect: the polystyrene board with flammability of B2 grade is still used as the sandwich core, instead of the A-grade inorganic thermal insulation and fireproof material with fire resistance and heat preservation performance
