Light carcass for cast-in-situ concrete stuffing

Abstract

The invention provides a light carcass used for filling cast-in-situ concrete, comprising a light carcass (1) with the bulk density lighter than that of the concrete. The light carcass is characterized in that the light carcass (1) is provided with a locking part (2) which comprises a self-locking hole (3) and a self-locking strip or a self-locking belt (4). The locking part (2) is anchored inside the light carcass (1) by an anchor component (5); alternatively, the locking part (2) is connected with the anchor component (5) which is anchored inside the light carcass (1); the self-locking hole (3) passes through the self-locking strip or the self-locking belt (4) movably; the locking part (2) passes through the light carcass (1) and extends out of the light carcass for exposal (1). The light carcass used for filling cast-in-situ concrete is applicable for the hollow floor plates, floors, walls, foundation soleplates and hollow bridges of cast-in-situ reinforced concrete or pre-stress reinforced concrete, especially for the hollow no-beam floors.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 26, 2004, an application number of 200410155258.5, and a title of "a lightweight carcass for filling cast-in-place concrete". (1) Technical field [0002] The invention relates to a lightweight carcass for filling cast-in-place concrete. (2) Background technology [0003] At present, the cast-in-place concrete floor is a widely used floor structure. The lightweight permanent tire mold filled in it has 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 formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a p...

Problems solved by technology

However, this kind of building components is inconvenient in design and construction. When it is applied to the cast-in-place concrete floor, it is prone to misalignment in the horizontal or vertical direction of the building components, which affects the construction quality of the floor and affects the construction efficiency.
