Problems solved by technology
However, after being applied to the hollow floor, the cast-in-place concrete ribs formed between the cavity formwork members are all rectangular cast-in-place concrete ribs, and their mechanical performance is not very reasonable, so it is often necessary to increase the cross-sectional size of the cast-in-place concrete ribs , increase the amount of steel bars and concrete, and increase the cost of the floor. At the same time, there is no force-bearing and force-transmitting member of the floor in this cavity formwork member, especially when the cavity formwork member is larger in size, it will be more obvious

Embodiment Construction
[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0055] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and lower bottom 3, and the upper plate 1, surrounding side walls 2, and lower bottom 3 form a polyhedral cavity formwork member, which is characterized in that the cavity formwork At least one transverse corner of the lower bottom of the component is a female corner 4, and there is at least one vertical hole 5 for pouring in-situ concrete on the cavity formwork component, which runs through the surface of the upper plate 1 of the cavity formwork component, and the other end is connected Go to bottom 3. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is the upper plate, 2 is the surrounding side wall, 3 is the bottom, 4 is the inner corner, and 5 is the vertical ...

The present invention provides an evacuated shuttering member including upper plate (1), a peripheral lateral wall (2), a bottom (3), the upper plate (1), the peripheral lateral wall (2), the bottom (3) compose the polyhedron evacuated shuttering member, which is characterized in that at least a lateral direction angle on bottom of the evacuated shuttering member is a hidden angle (4), a least a vertical hole (5) for cast-in-situ concrete pronging the upper plate (1) surface of the evacuated shuttering member on the evacuated shuttering member, and the other end connects to the bottom (3). Thus after the evacuated shuttering member is used for cast-in-situ building cover, the cast-in-situ bar between the evacuated shuttering member is inverse T shape, meantime, cast-in-situ concrete enters the hole shuttering cavity to form a cast-in-situ concrete column or bar, such that a stress and transmission member is formed in the evacuated shuttering member, which is suitable for cast-in-situ concrete or pretension steel bar concrete building, building cover, wall body, base bottom plate and open web bridge.
Description
(1) Technical field [0001] The present invention relates to a cavity formwork member. (2) Background technology [0002] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. 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 the patent No. ZL00203695.9 applied by Liang Jun, Shijiazhuang City, Hebei Province on February 23, 2000, and the name is called "combined concrete hidden rib floor cover plate" utility model patent, which discloses a formwo...
