Embodiment Construction
[0071] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0072] As shown in the accompanying drawings, the present invention includes a hollow carcass 1, which is formed by an outer wall 2, with a cavity 3 in it, and is characterized in that the upper or lower outer wall 2 of the hollow carcass 1 is a prefabricated panel wall 4 and The slurry embryo body 5 is made of soft and hard superimposed cementation and hard solidification. The prefabricated board wall 4 and the slurry embryo body 5 are made of inner hard outer soft superimposed cementation and hard solidification. The upper or lower outer wall 2 has reinforcements 6 and the cavity 3 There are no reinforcements 18 inside. In the drawings, 1 is a hollow body, 2 is an outer wall, 3 is a cavity, 4 is a prefabricated wall, and 5 is a slurry embryo. In the following drawings, the numbers are the same, and the descriptions are the same. like figure 1 As shown...

The invention discloses a hollow matrix used for filling field casting concrete, which comprises the hollow matrix (1) which is formed by the enclosing of an outer wall (2) and internally provided with a cavity (3); the matrix is characterized in that: the upper part or the lower part of the outer wall (2) of the hollow matrix (1) is made by the soft and hard superposition, cementation and hardening of a precast board wall (4) and a slurry green body (5); the precast board wall (4) and the slurry green body (5) are formed through superposition, cementation and hardening with hard interior and soft exterior; the upper part or the lower part of the outer wall (2) is provided with a reinforcement (6) and the cavity (3) is internally provided with no stiffener (18). The hollow matrix is applicable to field casting reinforced concrete or prestressed reinforced concrete hollow slabs, floors, roofs, walls, foundation base plates and bridges and being particularly applicable to hollow girderless floors.
Description
[0001] This application is a divisional application of an invention patent application with an application date of August 11, 2004, an application number of 200410155218.0, and the title of "a hollow carcass for filling cast-in-place concrete". (1) Technical field [0002] The invention relates to a hollow carcass for filling cast-in-place concrete. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used form of floor structure. The lightweight permanent molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent number ZL99249798.1 filed by the applicant on November 29, 1999 and the utility model patent titled "Fiber-reinforced thin-walled member for reinforced concrete filling" discloses a thin-walled formwork member, including an upper plate, The surrounding side wall, the lower bottom, the upper plate, the surrounding side wall and the lower bottom form a polyhedral ...
