The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples are only used to explain the present invention and are not used to limit the scope of the present invention. The preferred embodiments of the present invention are further described in detail below in conjunction with Figures 1-3:

As shown in Figures 1-3, a preferred beam formwork reinforcement support tool of the utility model includes a support pole 1, a support top bracket 2 and a driving assembly 3. The support pole 1 is adjustable in length. The support pole 1 includes a fixed pole 101 at the bottom and an adjusting screw 102 at the top. The bottom of the adjusting screw 102 is inserted into the fixed pole 101 and can slide freely along the fixed pole 101. The top of the adjusting screw 102 is installed on the support top bracket 2 through a bearing to ensure that the adjusting screw 102 can rotate freely relative to the support top bracket 2. The fixed pole 101 is preferably made of steel pipe, and the bottom of the steel pipe can be installed by plugging. There is a support base 104 with a larger ground contact area or a plurality of diagonal bracing steel pipes are set up at the bottom of the fixed pole 101 through fasteners to improve the stability of the fixed pole 101. An annular slide groove 103 is opened on the top tube wall of the fixed pole 101. The cross section of the slide groove 103 is dovetail-shaped, and a driving component 3 for controlling the extension length of the adjusting screw 102 is installed between the fixed pole 101 and the adjusting screw 102. In order to facilitate the construction personnel to adjust the length of the support pole 1 through the driving component 3, the height of the fixed pole 101 is preferably set to about 1.4-1.6m to ensure that the driving component 3 is located at the chest position of the construction personnel;

As shown in FIG3 , the driving assembly 3 includes a first bevel gear 301 and a second bevel gear 303. The first bevel gear 301 is sleeved on the adjusting screw 102 and is threadedly connected to the adjusting screw 102. A dovetail-shaped slider 302 adapted to the slide groove 103 is fixed at the bottom of the first bevel gear 301, and the slider 302 is slidably embedded in the slide groove 103. The second bevel gear 303 is installed on the fixed vertical rod 101 through an adapter seat 304, and the second bevel gear 303 can rotate relative to the adapter seat 304. The second bevel gear 303 is connected to the first bevel gear 301. The bevel gears 301 are meshed and connected, and a driving handle 305 is fixed on the outside of the second bevel gear 303 to drive it to rotate. In order to prevent the adjusting screw 102 from sliding down in the working state, it is necessary to lock the adjusting screw 102 after it is adjusted into place. The locking method can be achieved by setting a ratchet pawl assembly at the driving assembly 3 to prevent reverse flow or by self-locking the adjusting screw 102 and the first bevel gear 301, that is, the lead angle of the adjusting screw 102 is designed to be less than or equal to the friction angle between the adjusting screw 102 and the first bevel gear 301;

The support bracket 2 includes a bracket 201, a mounting groove is provided on the top of the bracket 201, and an adjusting screw 203 is passed through the mounting groove. Both ends of the adjusting screw 203 are mounted on the bracket 201 through bearings to ensure that the adjusting screw 203 can rotate freely relative to the bracket 201 at both ends of the mounting groove. The threads on both sides of the adjusting screw 203 rotate in opposite directions, and a clamping plate 202 is installed on each of the rod bodies on both sides of the adjusting screw 203. The clamping plate 202 and the adjusting screw 203 form a ball screw structure, and the clamping plate 202 can slide along the mounting groove. One end of the adjusting screw 203 extends out of the bracket 2. 01 is connected to a rotating handle 204, and a non-return mechanism is also arranged between the adjusting screw 203 and the bracket 201. When the non-return mechanism is in a working state, the adjusting screw 203 can only rotate in one direction. When the non-return mechanism is in a non-working state, the adjusting screw 203 can rotate in both directions. The specific non-return mechanism can have a variety of design forms, such as achieving non-return by clamping the rotating handle 204 with a pluggable blocking bolt, or installing a ratchet at the end of the adjusting screw 203, and then correspondingly installing a pawl on the bracket 201, and achieving non-return of the adjusting screw 203 through the cooperation of the ratchet and the pawl.

During specific use, firstly, several groups of reinforcement support tools are arranged at intervals below the extension direction of the structural beam 5, and then the height of the support upright 1 is adjusted according to the design elevation and cross-sectional size of the structural beam 5 (the adjustment screw 102 is driven by rotating the driving handle 305 to achieve extension and retraction) and the distance between the two clamping plates 202 of the support top support 2 are adjusted (the distance is adjusted by rotating the rotating handle 204), and then the beam template 4 is installed on the support top support 2 and the position is fine-tuned and checked after installation. In order to improve the support stability of each reinforcement support tool, several reinforcement support tools can be connected into a whole through steel pipes to ensure the overall force.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
