Problems solved by technology

But this kind of formwork member is in the cast-in-place concrete hollow slab, and the formed cast-in-place concrete hollow slab must be equipped with components such as fire detectors, such as temperature detectors, infrared detectors, etc., to improve the cast-in-place concrete hollow slab. The fire alarm performance of the slab, but this is often drilled on the newly repaired cast-in-place concrete hollow slab, and then installed, and it is very troublesome to repair the bottom of the cast-in-place concrete hollow slab after installation

Abstract

A concrete hollow board casting on-site comprises an inner hollow mold and an outer reinforcement concrete. The molds are arrayed side by side with cross gap in between. At casting concrete forms reinforcing bars in cross gaps. The mold includes upper board, side boards and bottom board / bottom board with an extruded part. At least one fire sensor is fixed on the bottom board or the extruded part. The bottom board is of the same surface with the concrete board.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, the cast-in-place concrete hollow slab 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 number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is called "a kind of cavity structure formwork for cast-in-place reinforced concrete floor slab" pat...
