[0015] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.
[0016] Reference Figures 1 to 3The utility model discloses an adjustable steel-concrete composite floor bottom formwork support device, comprising two parallel vertical columns 2, a horizontal square tube support is arranged between the two vertical columns 2, the length of the horizontal square tube support can be adjusted, so that the distance between the two vertical columns 2 can be adjusted, and a clamping plate 1 is arranged on the two vertical columns 2, and the clamping plate 1 can move up and down on the surface of the vertical column 2. The clamping plate 1 is used to fix the lower flange plate of the frame steel beam, and the upper flange plate of the frame steel beam is fixedly connected to the floor bottom formwork by a fastening screw 7. In the utility model, the length of the horizontal square tube support is adjustable so that the distance between the two vertical columns 2 can be adjusted. The distance between the two columns is adjustable, so the horizontal distance between the steel frame beams on the two columns is adjustable, so that when the steel frame beams support the floor bottom formwork, more or fewer steel frame beams can be selected according to actual conditions, as long as the required supporting strength is reached, it is suitable for floor decking support systems of various spans. In addition, a clamping plate 1 that moves up and down is arranged on the vertical column 2. The position of the clamping plate 1 is variable, so that the clamping plate 1 can clamp steel frame beams of different heights at different positions, so that the steel frame beam is suitable for floor steel beams of various heights. At the same time, the clamping plate 1 is fixedly designed, so that the lower support frame system can be cancelled, saving a lot of steel.
[0017] The horizontal square tube support in the utility model includes a horizontal inner rod 3 and a horizontal outer rod 4, one end of the horizontal inner rod 3 and the horizontal outer rod 4 are respectively fixedly connected to the vertical column 2, and the other end of the horizontal inner rod 3 can be inserted into the horizontal outer rod 4 so that the overlapping area of the horizontal inner rod 3 and the horizontal outer rod 4 becomes larger or smaller, and the horizontal inner rod 3, the horizontal outer rod 4 and the vertical column 2 are connected and fixed by fixing screws 6. When the horizontal square tube support of the utility model is assembled, the horizontal inner rod 3 is first installed and fixed to the top side of one vertical column 2 by fixing screws 6, and then the horizontal outer rod 4 is installed and fixed to the top side of another vertical column 2 by fixing screws 6. The horizontal outer rod 4 is hollow, so that the horizontal inner rod 3 can be inserted into the horizontal outer rod 4 to complete the length adjustment of the horizontal square tube support. Therefore, the horizontal distance of the steel frame beams located on the two vertical columns 2 is adjustable, so that when the steel frame beams support the floor bottom formwork, more or fewer steel frame beams can be selected according to actual conditions.
