Embodiment Construction
[0070] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0071] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and a lower bottom plate 3; , At least one of the lower bottom plate 3 is provided with a reinforcing rib 4, which is characterized in that at least one end of at least one hollow rod mold 5 intersects with at least one reinforcing rib 4 in the closed cavity and is connected into one body, at least one of the hollow rod mold 5 One end communicates with the outside of the formwork member. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is an upper plate, 2 is a surrounding side wall, 3 is a lower base plate, 4 is a reinforcing rib, and 5 is a hollow rod formwork. In the following accompanying drawings, those with the same number have the same description. Such as...

A permanent shuttering used in armored concrete filling comprises upper board, side walls, and lower board, which form a closed cavity shuttering device. There is the reinforcing bar on at least one of the upper board, side walls, and lower board. Its feature lies in: there is at least one hollow bar mould in the closed cavity, at least one of whose ends crosses and connects with at least one reinforcing bar and is interconnected with the outer of shuttering device. Thus, the intensity and rigidity of permanent shuttering are strengthened; its abilities of bearing stress and passing stress are increased greatly and especially its ability of bearing concentrated load is reinforced greatly. Used in hollow roofs of field laying armored concrete, the field laying armored concrete enters the cavity of the hollow bar mould and forms composite reinforcing bar, which further increases its mechanical property. The permanent shuttering device is adaptable to the hollow roofs, walls, soleplates and hollow bridge of field laying armored concrete or prestressing force armored concrete.
Description
(1) Technical field [0001] The invention relates to a permanent formwork for concrete filling. (2) Background technology [0002] 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 plate, the upper plate, the surrounding side walls and the lower bottom plate form a polyhedron 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 f...
