[0002] As one of the main structural components of industrial buildings, beams usually have large spans, and their sizes, types, structures and support requirements vary. In order to meet their casting requirements, specific fixtures are needed to clamp the beam templates to prevent the beam templates from being displaced during the casting process. At present, there are many types of fixtures used in engineering, mainly including assembly type, combination type and telescopic type. Among them, the assembly type is composed of multiple small parts. When used, the relevant parts need to be installed in combination with the actual construction situation. There are many parts, poor integrity, cumbersome installation and disassembly operations, and low efficiency. The combination type is between the assembly type and the telescopic type. Its main components have been assembled into a whole, but the components used to fix the fixture and adjust the height need to be installed on site during construction. The telescopic type adopts an integrated design and can be adjusted according to the width of the beam section, but it is insufficient in adjusting the beam height. In addition, the above-mentioned fixture is limited to the integrated design of the traditional beam fixture components, focusing on the side pressure of the beam during casting, and insufficient consideration of the bottom pressure of the beam. There is a lack of design that integrates the keel that bears the bottom pressure of the beam into the beam fixture structure. Utility Model Content

It is arranged on the side wall of the bottom supporting rod and extends along the length direction of the bottom supporting rod. The lead screw is supported by an end fixing plate and a middle fixing plate. The end fixing plate and the middle fixing plate are horizontally arranged in the bottom supporting rod. The lead screw has a tail end connected to the middle fixing plate through a ball joint, and a head end extending out of the end plate of the bottom supporting rod to constitute a power input end. The side clamping vertical rod is provided with a base part and an extension part, and the extension part is composed of a plurality of standard sections, and the standard section is connected to the base part and the standard section on one side by a hinge and on the other side by a snap connection.

DETAILED DESCRIPTION

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0019] See also Figures 1 to 9 An adjustable beam formwork fixture comprises a horizontally arranged bottom supporting rod 1 and two side clamping upright rods 2, wherein the cross sections of the side clamping upright rods 2 and the bottom supporting rod 1 are both rectangular.

[0020] The bottom of the side clamping upright 2 is connected to the bottom supporting rod 1 through a sliding sleeve 3, and the sliding sleeve 3 is driven by a spiral transmission mechanism. The spiral transmission mechanism is provided with a lead screw 4-1 and a nut 4-2, and the nut 4-2 is arranged at the center of the sliding sleeve 4, and the two sides are connected to the sliding sleeve 3 through a sliding rod 4-3, and the sliding rod 4-3 passes through a guide groove 4-4, and the guide groove 4-4 is arranged on the side wall of the bottom supporting rod 1 and extends along the length direction of the bottom supporting rod 1, and the lead screw 4-1 is supported by an end fixing plate 4-5 and a middle fixing plate 4-6, and the end fixing plate 4-5 and the middle fixing plate 4-6 are horizontally arranged in the bottom supporting rod 1, and the lead screw 4-1, the tail end is connected to the middle fixing plate 4-6 through a ball joint 4-7, and the head end extends out of the end plate of the bottom supporting rod 1 to constitute a power input end.

[0021] The side clamping upright 2 is provided with a base part 2-1 and an extension part 2-2. The extension part 2-2 is composed of a plurality of standard sections 2-3. The standard sections 2-3 are connected to the base part 2-1 and the standard sections 2-3 on one side by a hinge 2-4 and on the other side by a buckle 2-5.
