Abstract

The invention relates to a pre-installed recycled aggregate grouting concrete energy-saving heat-preservation block and a wall system. The thermal insulation block is made of broken bricks and tiles as recycled aggregate and cement slurry with certain strength as cementing material.

The invention makes full use of the thermal insulation performance of building waste such as bricks and tiles, improves the bearing capacity and integrity of the wall structure, and at the same time facilitates the semi-industrialization of masonry structure construction and significantly improves construction efficiency.

Description

A method for making a pre-installed recycled aggregate grouted concrete energy-saving and heat-insulating block and a wall system

Technical field

The invention relates to a new type of energy-saving thermal insulation block and a wall system made of the block, which has the advantages of energy saving, heat preservation, and improvement of the wall bearing capacity and integrity, and is beneficial to realize the semi-autonomous construction of the masonry structure wall. industrialization. the

Background technique

With the deepening of wall reform, clay bricks gradually withdraw from the construction market. Due to the unprecedented increase of broken bricks and tiles waste generated by house demolition, it is estimated that it will reach 30%-50% of the total construction waste. With a large amount of construction investment such as land acquisition, and the resulting problems of scattering and dust, it also aggravates the pollution of the environment. If it is recycled as a resource, it will be of great significance. In addition, concrete small hollow blocks have been widely used as the main material of walls, but they have problems such as poor thermal insulation performance, poor integrity, and low labor productivity. However, the existing lightweight thermal insulation materials have complex production processes and high costs. the

The invention makes full use of the broken brick and tile waste, on the one hand, it can solve the problems such as the difficulty in handling a large amount of broken brick and tile waste and the negative impact on the environment, reduce the mining of natural sand and stone, and protect the ecological environment; on the other hand, it can use brick and tile Excellent thermal insulation production blocks, environmental protection, energy saving and waste utilization. In addition, the present invention improves the bearing capacity and integrity of the wall by using the clamping steel mesh and the horseshoe-shaped reinforced masonry block to form a reticulated reinforced block wall. the

Contents of the invention

The purpose of the present invention is to make full use of the thermal insulation performance of construction waste such as broken bricks and tiles, overcome the complexity of the existing thermal insulation block manufacturing process, reduce costs, and provide a thermal insulation block with simple manufacturing process and low cost and high bearing capacity. A highly integrated energy-saving wall system. the

The technical scheme adopted by the present invention to solve the technical problem is: to make energy-saving and heat-preserving blocks by pre-installing recycled aggregate grouting concrete; At the ribs and structural columns, the well-shaped steel mesh is used to build thermal insulation blocks to form a network reinforced block wall system. the

The thermal insulation blocks are made of waste broken bricks and tiles, cement slurry as cementing material, and special molds and preset recycled aggregate grouting methods are used to make blocks. The aggregates can also be light bone such as gravel or slag. The cement slurry can be foamed cement slurry prepared by physical foaming method, ordinary cement slurry mixed with fly ash and other admixtures, or other cementing material slurry. When the anti-seismic requirements are high, a steel cage is installed inside the block to improve the integrity of the block, and horseshoe-shaped reinforcement is provided on both sides of the block for the horizontal connection between the blocks. When the block is prefabricated, the arc-shaped end of the reinforcement can be bent upward Fold it 90° so that it just fits against the mold. the

The special mold mentioned above is a combined mold made of steel or other materials with sufficient strength for easy installation and disassembly. The lower part of the mold is provided with drainage holes. If it is necessary to prefabricate blocks at the site of construction waste, handle and lifting points. the

The production process of the thermal insulation block is as follows: Assemble the surrounding side molds on the bottom mold, put in the steel cage, put the aggregate into the mold at the crushing site of the recycled aggregate, wash the aggregate with clean water after transporting it back to the prefabrication plant, and prevent the blockage Sewage hole, pour cement slurry and vibrate the mold, remove the side form after reaching the strength of side form removal, lift the component from the bottom form after reaching the lifting strength. the

When the above-mentioned reticulated reinforced block wall is built, the clamped steel mesh is used to tie the blocks in the horizontal mortar joints, and the longitudinal reinforcement of the reinforcement mesh is placed at the lower part of the horizontal reinforcement, that is, each block In the upper groove, a vertical bar is inserted in the middle of the horseshoe-shaped reinforcement between the blocks in the vertical mortar joint. The horseshoe-shaped reinforcement can also be used for hoisting blocks, and the well-shaped welded reinforcement is used for the structural column The mesh and stirrup are used to fix the insulation board of the structural column with a comb. the

The beneficial effect of the present invention is that on the one hand, the thermal insulation blocks make full use of the thermal insulation properties of construction waste such as bricks and tiles, the manufacturing process is simple, and the cost is low. The technology is simple and easy, and on the other hand, it can significantly improve construction efficiency, reduce building energy consumption, and improve the bearing capacity and integrity of the wall structure.

Detailed ways

The implementation steps of the present invention are as follows: firstly make heat-insulating blocks, assemble the surrounding side molds on the bottom mold, put them into steel cages, put the aggregates into molds at the broken site of recycled aggregates, and wash the aggregates with clean water after transporting them back to the prefabrication plant , Block the sewage hole, pour cement slurry and vibrate the mold, remove the side form after reaching the removal strength of the side form, lift the component from the bottom form after reaching the lifting strength, and form a recycled aggregate insulation block. Then build the thermal insulation block wall, place the welded clamping steel mesh in the horizontal mortar joint, insert a vertical bar in the middle of the horseshoe-shaped set of bars between the blocks in the vertical mortar joint, After the masonry of the wall is completed, vertical steel bars and well-shaped welded steel mesh pieces are bound at the positions of the structural columns, and the insulation layer is fixed with comb boards, and finally concrete is poured. A pre-installed recycled aggregate grouting concrete energy-saving and thermal insulation block wall is formed. the
