Technical Field

[0001] This utility model relates to the field of engineering technology, and in particular to an adjustable building formwork support frame. Background Technology

[0002] Construction formwork support frames are indispensable temporary load-bearing structures in construction. Their main function is to support the formwork system during the concrete pouring process, ensuring that the formwork remains stable under the weight of the concrete, construction loads, and vibrations, and ultimately ensuring that the concrete components are formed according to the design dimensions and shape.

[0003] Currently, there are still some shortcomings in the construction formwork support frame. The height of the construction formwork support frame is fixed, which cannot be used for construction formwork of different heights. When facing changes in height, different specifications of support frames need to be replaced, which results in the need to keep a large number of different models of support frames on the construction site, which is quite inconvenient. Summary of the Invention

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] like Figures 1 to 4 As shown, an adjustable building formwork support frame of this utility model includes a base plate 1, a bidirectional screw 2 rotatably connected to the inner surface of the base plate 1, a slide block 3 threadedly connected to the outer surface of the bidirectional screw 2, a fixed column 4 fixedly connected to the inner surface of the slide block 3, a long strip plate 5 rotatably connected to the outer surface of the fixed column 4, a connecting column 6 rotatably connected to the inner surface of the long strip plate 5, a connecting seat 7 fixedly connected to the outer surface of the connecting column 6, a U-shaped frame 8 fixedly connected to the outer surface of the connecting seat 7, and a support plate 9 fixedly connected to the upper surface of the U-shaped frame 8.

[0022] In this utility model, an adjusting seat 10 is fixedly connected to the upper surface of the base plate 1. A through groove 11 is provided on the outer surface of the adjusting seat 10. A guide rod 12 is fixedly connected to the inner surface of the through groove 11. A sliding groove 23 is provided on the upper surface of the base plate 1. The inner surface of the sliding groove 23 is slidably connected to the slide 3 to limit the movement of the slide 3. There are two long strips 5, which are symmetrically distributed and used to adjust the height of the support plate 9. The outer surface of the adjusting seat 10 is slidably connected to the U-shaped frame 8. The outer surface of the guide rod 12 is slidably connected to the U-shaped frame 8. The inner surface of the through groove 11 is slidably connected to the U-shaped frame 8 to limit the movement of the U-shaped frame 8.

[0023] In this utility model, an L-shaped fixing plate 13 is fixedly connected to the upper surface of the base plate 1, a first conical tooth 14 is fixedly connected to the outer surface of the bidirectional lead screw 2, a transmission shaft 15 is rotatably connected to the inner surface of the L-shaped fixing plate 13, a second conical tooth 16 is fixedly connected to the outer surface of the transmission shaft 15, and a turntable 17 is fixedly connected to the outer surface of the transmission shaft 15. The first conical tooth 14 and the second conical tooth 16 mesh with each other.

[0024] In this utility model, a pin 18 is slidably connected to the inner surface of the turntable 17, a limiting ring 19 is fixedly connected to the outer surface of the pin 18, a spring 20 is provided on the outer surface of the pin 18, a handle 21 is fixedly connected to the upper end of the pin 18, a limiting groove 22 is provided on the upper surface of the L-shaped fixing plate 13, the inner surface of the limiting groove 22 is adapted to the pin 18, and there are multiple limiting grooves 22 arranged in a circular array to facilitate limiting the rotation of the bidirectional lead screw 2. The outer surface of the limiting ring 19 is slidably connected to the turntable 17, the upper end of the spring 20 is in contact with the turntable 17, and the lower end of the spring 20 is in contact with the limiting ring 19.

[0025] In this invention, during operation, pulling the handle column 21 upwards causes the pin column 18 to disengage from the corresponding limiting groove 22. Under the action of the limiting ring 19, the spring 20 is compressed. Then, with the transmission shaft 15 as the axis, the handle column 21 drives the turntable 17 to rotate. This, in turn, drives the bidirectional screw 2 to rotate under the meshing action of the second conical tooth 16 and the first conical tooth 14. This then drives the slide seats 3 on both sides to move towards each other along the interior of the slide groove 23. Under the hinge action between the slide seats 3, the fixed column 4, the long strip plate 5, the connecting column 6, and the connecting seat 7, the U-shaped frame 8 moves up and down along the adjusting seat 10 inside the through groove 11, thereby adjusting the support height of the support plate 9 to accommodate building templates of different heights. After the height of the support plate 9 is adjusted, simply releasing the handle column 21 causes the pin column 18 to insert into the corresponding limiting groove 22 under the rebound force of the spring 20, thereby limiting the rotation of the bidirectional screw 2 and improving the support stability of the entire device.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
