Embodiment Construction
[0058] The present invention will be further described below in conjunction with the drawings and embodiments.
[0059]As shown in the drawings, the present invention includes an upper shell 1, a peripheral side shell 2, and a lower shell 3. The upper shell 1, the peripheral side shell 2, and the lower shell 3 surround each other to form a closed cavity 4, and the cavity 4 is provided with At least one bearing support 5, characterized in that at least one of the upper shell 1, the surrounding side shell 2, the lower shell 3, the bearing support 5 itself or the corner part between each other has a slurry embryo body cemented joint At least one cemented joint 6 is connected together, and the corner of the corner where the cemented joint 6 is located is a female corner 11 or an arc corner 9 or a chamfer 10 or a broken line corner 12 or a positive corner 13. Fig. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In the drawings, 1 is the upper shell, 2 is t...

The invention provides a cavity shuttering member which includes an upper shell (1), a surrounding side shell (2) and a lower shell (3) that form a closed cavity (4); at least one bearing support member (5) is arranged in the cavity (4) . The invention is characterized in that at least one of the individual or mutual corner positions of the upper shell (1), the surrounding side shell (2), the lower shell (3) and the bearing support member (5) have at least one agglutinated joint gap (6) which is bonded and jointed by slurry embryonic plant; the corner of the corner position where the agglutinated joint gap (6) is located at is an inside corner (11) or a camber corner (9) or a chamfer corner (10) or a polygonal line corner (12) or an outside corner (13). In this way, the invention is applicable to constructing a hollow building floor, a house floor, a wall, a foundation mat and a hollow bridge with cast-in-situ reinforced concrete or pre-stressed reinforced concrete, and is especially suitable for the construction of a hollow flat slab floor.
Description
[0001] This application is a divisional application for the invention patent application whose application date is May 25, 2004, the application number is 200410037062.6, and the name is "a cavity mold shell". (1) Technical field [0002] The invention relates to a cavity mold shell. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure, and the light permanent tire mold filled in it has a hollow tube and a cavity mold shell component. For example, the applicant applied for a patent number ZL99249798.1 on November 29, 1999, 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, the upper plate, the surrounding side walls, and the lower bottom enclose a polyhedral cavity. Another example is the applicant’s application number 01140106.0 and publication numbe...
