Light moulding bed component for concrete filling

Abstract

Disclosed is a lightweight tire shuttering member for concrete filling comprising a tire body (1), wherein at least one lateral surface (2) of the tire body is in contact with the lower bottom (3) by a transverse bottom rib groove (4), and at least one lateral surface (2) is provided with a groove (6) penetrating the upper surface (5) and the transverse bottom rib groove (4), a vertical internal corner (7) is arranged on at least a vertical corner position of the same lateral surface (2) penetrating the upper surface (5) and th etransverse bottom rib groove (4), at least two tire bodies (1) are arranged at intervals, and are connected integrally by the lower bottom (3) or / and connection member (18). The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of November 2, 2003, an application number of 200310103976.3, and a title of "a lightweight tire mold member for concrete filling". (1) Technical field [0002] The invention relates to a lightweight tire mold member for concrete filling. (2) Background technology [0003] Beamless floor is currently the most widely used floor structure for cast-in-place concrete floors. It has the advantages of fast construction speed, small structural height, flexible division of indoor areas and no need for ceiling decoration. The lightweight permanent tire mold filled in it There are various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99232921.3, which the applicant applied for on March 10, 1999, is a utility model patent named "thin-walled tube for filling cast-in-place reinforced concrete", which consists of a hard thin-walled tube and t...

Problems solved by technology

However, whether it is a hollow tube or a box, after it is applied to the floor as a lightweight permanent matrix, it can form a one-way cast-in-place concrete rib hollow floor or a two-way cast-in-place concrete ribbed hollow floor, but it cannot form a shear bond type. Two-way hollow floor, although Guizhou University of Technology has applied for a utility model patent with a patent number of ZL97200102.6 named "Reinforced Concrete Shear Key Type Two-way Hollow Slab", which discloses a shear key type two-way hollow floor, It has the characteristics of light weight, mechanical performance, good seismic performance, and flexible division of building space, but its construction is very difficult, time-consuming and laborious
