Light structural component for filling concrete

Abstract

A lightweight component for concrete filling, comprising a lightweight component (1), characterized in that the lightweight component (1) has at least one pouring hole (2) running vertically up and down, and the lightweight component (1) There is at least one groove (3) intersecting and communicating with at least one end of the pouring hole (2) on the surface, and there is at least one groove (3) parallel to the pouring hole (2) on the lightweight component (1), and the reinforcing rib (10) It is arranged on the upper wall and the lower wall inside the lightweight component, and the superimposed layer (8) is superimposed on at least one surface of the lightweight component (1). It is suitable for hollow floors, roofs, walls, foundation slabs and hollow bridges of cast-in-place reinforced concrete or prestressed reinforced concrete.

Description

[0001] This application is a divisional application for an invention patent application whose application date is November 2, 2003, the application number is 200310103956.6, and the name is "a lightweight component for concrete filling". (1) Technical field [0002] The invention relates to a lightweight component for concrete filling. (2) Background technology [0003] The beamless floor is the most widely used floor structure of cast-in-place concrete floor at present. It has the advantages of fast construction speed, small structure height, flexible division of indoor areas and no ceiling decoration, etc. The light components filled inside have various This kind of hollow tube and box, the box can be hollow or solid. For example, the patent number applied for by the applicant on March 10, 1999 is ZL99232921.3, the utility model patent named "Thin-walled tube for in-situ reinforced concrete filling", which consists of a hard thin-walled tube and two plugs. Used as a lightweight ...

AI Technical Summary

Problems solved by technology

After this type of lightweight component is applied to the floor, it can form a one-way cast-in-place concrete rib hollow floor or a two-way cast-in-place concrete dense rib hollow floor, but it cannot form a shear bond type two-way hollow floor. Although Guizhou University of Technology Applied for the patent No. ZL97200102.6, named "reinforced concrete shear key type two-way hollow slab" utility model patent, which discloses a shear key type two-way hollow floor, which has light weight, mechanical performance, and earthquake resistance Good performance, flexible division of building space, etc., but its construction is very difficult, time-consuming and laborious
