Bridge-cutoff self-insulation concrete block and fabrication technology thereof

Abstract

The invention relates to a bridge-cutoff self-insulation concrete block for building energy conservation and a fabrication technology of the block, and belongs to the technical field of building materials. The block is formed by combining a bridge-cutoff concrete hollow block provided with trapezoidal bulges and trapezoidal grooves and insulation materials, wherein the insulation materials are located in two cavities defined by the concrete hollow block; the concrete hollow block is fabricated from materials such as cement and fine stone, and provided with two bridge-cutoff connecting blocks to connect concrete; each bridge-cutoff connecting block consists of a plurality of glass fiber reinforcement ribs and polyurethane, and is fabricated in a bridge-cutoff connecting block mold; the glass fiber reinforcement ribs in the bridge-cutoff connecting blocks do not pass through the insulation materials of the block, so that the integrity of the insulation materials is kept. The block is applicable to construction of bearing and non-bearing walls, and has the advantages of high convenience in fabrication, good mechanical property, good insulation property, low cost and the like.

Description

[0001] 1. Technical field [0002] The invention relates to a broken bridge type self-insulating concrete block for building energy saving and a process for making the block, belonging to the technical field of building materials. [0003] 2. Background technology [0004] The construction industry is a field of rapid growth in energy demand. At present, my country's building energy consumption accounts for about one-third of the country's total energy consumption. There is a huge potential for building energy conservation. The construction industry has become a key industry for the country to implement energy conservation and emission reduction policies. At present, the external wall insulation technology that is mostly used in building energy conservation in my country has many problems such as cracking, hollowing, fire, and poor durability of the external wall insulation material. The external wall self-insulation technology is an integrated technology of energy saving and s...

AI Technical Summary

Problems solved by technology

The self-insulation block has the following problems: the left half block and the right half block must be connected with the insulation layer through a slot such as a dovetail groove, which causes complicated procedures when processing the block and the insulation layer, and improves the performance of the self-insulation block. Cost of production

Such a structure makes the connecting pin very long. If steel is used, it will become a path for heat transfer and affect the insulation effect.

If ordinary plastic pins are used, the connection force is weak and the overall strength of the block will be weak

Moreover, the connecting pin must pass through the insulation layer, which will inevitably cause damage to the insulation layer during block processing and affect the insulation effect of the insulation layer.
