Abstract

The invention relates to open-spandrel structural member. It includes open-spandrel form and bottom board. They are joined to entirety. The bottom board is set at least two open-spandrel forms. The lateral surface of the open-spandrel form is formed side formwork. Its features are that the open-spandrel form is covered by at least two upper and lower bottom boards; 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 May 26, 2003, the application number of 03124413.0, 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...
