Reinforced concrete lightweight board

Abstract

The invention discloses a reinforced concrete lightweight board, which comprises reinforced concrete (1) and solid lightweight components (2), wherein the solid lightweight components (2) are wrapped in the reinforced concrete (1) and are arranged at intervals, and cast-in-place reinforced concrete ribs (3) are arranged among the solid lightweight components. The reinforced concrete lightweight board is characterized in that: a cantilever slab (6) protrudes outwards along a bottom surface (5) on the circumferential lateral surface of at least one of the solid lightweight components (2); the bottom surface (5) is leveled with the bottom surface of the reinforced concrete lightweight board; the cantilever slab (6) is formed by setting and connecting the solid lightweight components (2) to a cement mortar or a cement concrete bottom plate (8); and the solid lightweight components (2) are foamed plastic blocks, expanded perlite blocks, expanded vermiculite blocks, foamed or aerated concrete blocks, haydite concrete blocks, straw husk cementing material blocks, charcoal concrete blocks or cement-cemented foam grain blocks. The reinforced concrete lightweight board is suitable for cast-in-place reinforced concrete or prestressing force reinforced concrete lightweight boards, floor systems, roofs, wall bodies, foundation slabs and bridges, and is particularly suitable for flat slabs.

Description

[0001] This application is a divisional application of an invention patent application with an application date of January 14, 2005, an application number of 20051000697948, and a title of "a light-weight slab for cast-in-place reinforced concrete". (1) Technical field [0002] The invention relates to a light-weight board of cast-in-place reinforced concrete. (2) Background technology [0003] At present, the cast-in-place reinforced concrete lightweight slab is a widely used floor structure, and the lightweight permanent tire mold filled in it includes various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled solid lightweight member, including The upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity surrou...

AI Technical Summary

Problems solved by technology

However, after this solid lightweight component is applied to the cast-in-place reinforced concrete lightweight slab, it still needs to support the construction formwork, which reduces the construction speed and increases the construction cost. Therefore, it is urgently needed to develop a new type of reinforced concrete lightweight slab.
