Abstract

Disclosed is a permanent shuttering member, which comprises an upper board (1), the peripheral side panels (2) and a lower bottom board (3), the upper board (1), the peripheral side panels (2) and the lower bottom (3) enclose a confined polyhedral hollow shuttering member, characterized in that at least a junction box (5) is fixed on at least one position of the upper board (1) and the peripheral panels (2), 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 the filing date of October 27, 2003 and the application number 200310104269.6 titled "A Permanent Formwork Component". (1) Technical field [0002] The present invention relates to a permanent formwork member. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. 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 polyhedral cavity. Another example is that the application numbe...
