Insulating board for composite insulating block and method for making same

Abstract

The thermal insulation board used for composite thermal insulation blocks and the manufacturing method thereof are provided with dovetail grooves on both sides of the thermal insulation board, transverse concave grooves on the upper and lower surfaces, and longitudinal concave grooves and longitudinal convex grooves on both ends. The longitudinal concave groove and the longitudinal convex groove are respectively provided with exhaust grooves, which are characterized in that the upper surfaces of the lateral sides of the thermal insulation board are respectively made into inclined drainage surfaces inclined in the direction of the lateral concave grooves on the upper surface, and the upper surface is laterally concave. The bottom surface of the groove is made of the inclined bottom surface of the drainage groove whose middle is inclined to the direction of the two end surfaces of the insulation board respectively. The various composite thermal insulation blocks made of the thermal insulation board of the present invention can solve the problems of removing water and gas such as moisture in the wall, indoor humidity, long hair on the wall, etc., and improve the life and quality of the building. It has the advantages of simple and reasonable structure, convenient processing, low cost, good performance, good thermal insulation and drainage of masonry walls, and wide application range.

Description

technical field [0001] The invention relates to the improvement of a thermal insulation board for making a composite thermal insulation block, and belongs to the field of construction engineering. Background technique [0002] At present, in the load-bearing or non-load-bearing walls of industrial and civil buildings, a large number of composite thermal insulation blocks are used. This composite thermal insulation block is composed of concrete load-bearing layer, thermal insulation board, concrete surface layer, etc., and has dual functions of load-bearing and thermal insulation. For example: The composite energy-saving block given in the invention patent No. 200310110002.8 "Composite energy-saving block and its manufacturing method" is composed of load-bearing blocks, insulation boards, surface layers, etc., and the upper and lower surfaces of the insulation board are respectively There is a transverse concave groove, a longitudinal concave groove is opened on one end surf...

AI Technical Summary

Problems solved by technology

[0004] However, after a period of engineering practice investigations, it was found that the walls built with this composite thermal insulation block still have moisture in the grooves of the thermal insulation boards in the wall, moisture in the inner wall of the outer wall, and hairy walls, etc. Eliminate long-term difficult-to-solve problems in water and air, which will affect the life and quality of the overall building

[0005] The main reason why these deficiencies still exist in anatomical analysis is that during construction, especially in the rainy season, after the composite thermal insulation block is wet by rain, the concave groove of the thermal insulation board is filled with water, and the construction personnel did not put the concave groove Remove the water in the wall, and it is not easy to discharge the water in the wall; in addition, when the water in the indoor air is distributed to the inside of the wall, the water is absorbed into the concrete of the inner wall, because the insulation board in the block The water absorption rate is very low, so that this part of the water cannot be dissipated from the inner wall. Over time, the phenomenon of dampness and hair growth will appear on the inner wall of the outer wall, and in severe cases, water droplets will form.

[0006] In addition, most of the thermal insulation boards used for composite thermal insulation blocks are cut from purchased benzene boards with resistance wires. In addition to the difficulty in achieving accurate structural shapes and specific dimensions, the polymer materials of benzene boards are heated by cutting resistance wires. , a closed electric fusion film is formed on the cutting surface, which hinders the evaporation of water in the insulation board, prolongs the self-shrinkage period, and reduces the performance of the composite insulation block

[0007] These deficiencies all bring hidden dangers to building construction, affect the life and quality of buildings, and seriously limit the popularization and application of such products.
