Problems solved by technology

However, after this kind of cavity component is applied to the hollow floor, due to the wall of the cavity formwork and the structural bottom plate, it is easy to be damaged in the process of handling and construction, especially when it is hit or collided by various heavy objects and falling objects. Not enough, the impact resistance is poor, and there are often damaged holes, which lead to the destruction of the cavity component, which brings inconvenience to the construction, increases the cost, and affects the construction period. Therefore, it is urgent to develop a new type of cavity component.

Embodiment Construction

[0076] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0077] As shown in the accompanying drawings, the present invention includes a cavity formwork 1 and a base plate 2, the cavity formwork 1 and the base plate 2 are connected as a whole, and at least two cavity formworks 1 are arranged alternately on the base plate 2, and its side faces and the base plate 2 Constitute at least one cast-in-place structure inner rib cavity 3, and the other outer side 4 of the cavity formwork 1 constitutes the side formwork of the cast-in-place structure outer rib or beam or wall, which is characterized in that the upper rib opening of the inner rib cavity 3 is covered with cover plate. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. Among the accompanying drawings, 1 is a cavity formwork, 2 is a base plate, 3 is an inner rib cavity, 4 is an outer surface, and 5 is a thin strip. In e...

Abstract

The invention relates to open-spandrel structural member. It includes cavity shuttering and bottom board. They are joined to entirety. The bottom board is set at least two open-spandrel forms. The surface of the open-spandrel form is formed side work. Its feature is that inner rib die cavity is covered by upper bottom board. It can be applied to hollow storey cover, room cover, wall body, foundation mat and hollow bridge of current cast reinforcement concrete or pre-stressed reinforcement concrete, especially for hollow mushroom floor.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of June 2, 2003, the application number of 03137269.4, and the title of "A Cavity Member". (1) Technical field [0002] The present invention relates to a cavity member. (2) Background technology [0003] At present, most buildings with brick-concrete structure and reinforced concrete structure use prefabricated hollow slabs as floor slabs, which have the advantages of fast construction speed and low cost. However, because there is no firm connection between two adjacent prefabricated hollow slabs, only cement mortar is used to fill the joints, so the integrity is poor, which is not conducive to earthquake resistance, and cracks and water seepage often occur in the gaps. In order to solve the above problems, many buildings adopt the method of cast-in-place concrete floor slabs (solid and hollow). Although the problems of earthquake resistance and cracking have been so...
