DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the specific implementation of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation of the utility model.

[0029] A template support structure includes a support portion, such as Figure 1 As shown, the support part includes: a first support plate 1 and a second support plate 2. A plurality of adjustment parts are symmetrically arranged between the two support plates to adjust the height of the support part; the adjustment part includes a bracket and a power member providing power to the bracket, and the adjustment part includes a load-bearing bracket 12, a load-bearing beam 11 and an adjustment frame 3 from bottom to top; the adjustment frame 3 is sleeved on the outside of the load-bearing bracket 12 and the load-bearing beam 11.

[0030] Specifically, the template support structure in this embodiment includes a support part and an adjustment part located therein, a first support plate 1 is provided above the adjustment part, and a second support plate 2 is provided below the adjustment part, and the adjustment part makes the two support plates separated by a certain distance, that is, the template support structure can support a certain height. The support plate is a rectangular plane plate, and there are multiple adjustment parts, which are symmetrically distributed between the two support plates, so that the first and second support plates are evenly stressed, balanced, and the support is more stable. In this embodiment, two adjustment parts are symmetrically provided at both ends of the edge of the support part, which can more effectively disperse and bear the weight on the support plate. Being arranged at the edge of the support part can disperse stress, reduce stress concentration, increase the stability of the support template, and make it more sturdy and durable.

[0031] In addition, the shape of the support plate and the number of adjustment parts can also be adjusted according to actual conditions: for example, the support plate can be circular, which can better disperse the pressure while adapting to the shape of the supported building; or more than three adjustment parts can be symmetrically arranged at both ends and the center of the support part, and the adjustment parts at both ends can fine-tune different heights, and the adjustment parts in the middle can provide more support, so that the first support plate 1 is tilted to cope with the situation where some buildings are tilted. Different structures or shapes are all to meet specific engineering needs.

[0032] Furthermore, if Figure 2 As shown, the load-bearing beam 11 is fixedly installed on the top of the load-bearing bracket 12, and the bottom end is fixedly connected to the second support plate 2. Specifically in this embodiment, the load-bearing bracket 12 is a U-shaped structure, and the brackets on both sides are parallel to each other and are vertically arranged on the base of the load-bearing bracket, and the base is fixed on the second support plate 2. The upper end of the load-bearing bracket 12 is vertically fixed to the load-bearing beam 11, and the length of the load-bearing beam 11 is greater than the opening width of the load-bearing bracket 12. Since the structures are perpendicular to each other, the load-bearing beam 11 and the second support plate 2 remain horizontal. The load-bearing beam 11, the load-bearing bracket 12 and the second support plate 2 are connected as a whole. The midpoints of the three are in a straight line, that is, the connected whole is a symmetrical structure, so that the load-bearing bracket 12 and the load-bearing beam 11 can be evenly stressed, and the same pressure is distributed to the supporting part on both sides, and the structure is more solid and durable.

[0033] Furthermore, the adjustment frame 3 is a hollow tubular structure, including a crossbeam 31 and two parallel tubes 32 vertically arranged at both ends of the crossbeam; a strip hole 13 is opened on the opposite side of the parallel tubes. Specifically in the present embodiment, the adjustment frame 3 is a U-shaped tubular structure with an opening downward, and the interior is hollow, in which parts can be installed. The two parallel tubes 32 are respectively fixed vertically at the edges of the two ends of the crossbeam 31. The distance between the two parallel tubes 32 is greater than the length of the load-bearing beam 11, so that the load-bearing beam 11 together with the load-bearing bracket 12 connected as one can move up and down in the adjustment frame 3. The inner sides of the two parallel tubes 32 opposite to each other are both provided with a strip hole 13, such as Figure 1As shown, the interior of the parallel tubes 32 can be accessed through the strip-shaped holes 13 .

[0034] Furthermore, the adjustment frame 3 also includes a first ball screw 5 and a second ball screw 7 which are respectively arranged in two parallel tubes 32 and spirally connected to the inner wall thereof. The ball screw is a transmission element with low friction loss and high transmission efficiency. There are many balls that perform rolling motion between the screw shaft and the screw nut of the ball screw, which can convert the rolling motion into linear motion. The up and down linear motion of the ball screw has high precision and stable motion, and can be transmitted in the forward or reverse direction. As an element for adjusting the height of the adjustment part, the high-precision and stable motion in the forward and reverse directions is more convenient for repeated debugging of the template height without repeatedly disassembling and assembling the screws. The two ball screws are respectively fixed to the two parallel tubes. In this embodiment, the inner bottom end of the parallel tube 32 is provided with a thread matching the ball screw. The ball screw is embedded in the thread and spirally tightened, so that it is firmly fixed inside the parallel tube 32 without shaking or falling off. In some embodiments, other fixing methods may also be used, such as spirally linking the ball screw with the top of the parallel tube and then using a cable tie to tighten the connection with the crossbeam 31, so that the ball screw and the adjustment frame 3 are fixed more firmly and used more reliably, and can cope with some extreme occasions.

[0035] Further, the outer wall of the first ball screw 5 can be connected with a first screw nut 6 in a spiral sliding manner; the outer wall of the second ball screw 7 can be connected with a second screw nut 8 in a spiral sliding manner; the two ends of the load-bearing beam 11 pass through the strip holes 13 on both sides and are fixedly connected with the first screw nut 6 and the second screw nut 8. Specifically, the length of the load-bearing beam 11 is longer than the opening width of the load-bearing bracket 12, and the two ends can enter the interior of the parallel tubes 32 on both sides through the strip holes 13, and are fixedly connected with the screw nuts fixed on the internal ball screw. The screw nuts move back and forth on the screw shaft of the ball screw, driving the load-bearing beam 11 and the load-bearing bracket 12 and the second support plate 2 connected thereto to move together. Relatively speaking, if the load-bearing beam 11 remains stationary, the screw nuts 6 and 8 connected thereto also remain relatively stationary, and the ball screw can be adjusted up and down in height, driving the adjustment frame 3 and the first support plate 1 connected thereto to change in height. In general, the back-and-forth transmission of the screw nut on the screw shaft enables the adjustment part to change the height of the support back and forth, thereby playing an adjustment role. When the lead screw nut moves to the top end of the ball screw, the load-bearing beam 11 together with the load-bearing bracket 12 are received into the adjustment frame 3 to realize the storage function.

[0036] Furthermore, if Figure 3As shown, the power member includes a stepper controller 14 and a brake stepper motor 4, both of which are arranged at the bottom end of the first support plate 1; the brake stepper motor 4 is fixedly connected to the top of the first ball screw 5. The stepper controller 14 is electrically connected to the brake stepper motor 4. The stepper controller 14 can be electrically connected to multiple brake stepper motors 4 to control the connected brake stepper motors 4 to be turned on or off at the same time. Specifically, the stepper controller 14 is a microprocessor and can be remotely controlled manually. The brake stepper motor is a motor with a brake (brake) device installed at the tail of the motor. When the motor is powered on, the motor operates normally; when the motor is powered off, the brake is released to hold the motor shaft, which plays a role in fixing the motor shaft, and can achieve power-off self-locking. In this embodiment, the brake stepper motor 4 is suitable for the vertical lifting movement of the adjustment part. The motor drives the rolling of the ball screw, thereby driving the load-bearing beam 11 to lift and lower, and can remain in its position when adjusted to any height, and can stay stably without screw fixation.

[0037] Furthermore, a synchronous wheel 9 is provided at the top end of any ball screw; a synchronous belt 10 is provided on the outer wall of the synchronous wheel 9 in the same adjustment frame 3, and the synchronous wheels 9 on both sides are connected by the synchronous belt 10.

[0038] Specifically, the synchronous wheel 9 is arranged at the top of the ball screw, and when the ball screw rolls, it can drive the synchronous wheel 9 to rotate together. The synchronous wheel 9 in the same adjustment part is connected to the synchronous belt 10, so that the two synchronous wheels 9 rotate at the same pace, and the ball screws on both sides can also keep the same speed and start or end the movement at the same time. The synchronous belt 10 reduces the vibration generated by the motor drive and the movement of the adjustment frame 3, and the lifting operation is more stable.

[0039] Furthermore, anti-skid pads are provided at the upper end of the first support plate 1 and the lower end of the second support plate 2. In some embodiments, rubber material can be used, or anti-skid protrusion structures can be added to the surfaces of the first and second support plates to improve the stability of the template support.

[0040] The beneficial effects that this embodiment may produce include:

[0041] 1. The motor can be used to drive the support structure to rise and fall, avoiding direct manual operation and ensuring construction safety; the structure adopts a ball screw with high sensitivity and high transmission efficiency, saving manpower.

[0042] 2. The overall structure can be adjusted in angle and height without removing screws, which greatly improves the efficiency of disassembly and assembly.

[0043] 3. The structure is symmetrical and stable, and the support is reliable. After use, the load-bearing bracket can be stored in the adjustment frame, which is convenient for transportation. It is suitable for supporting temporary building formwork and can be put into large-scale application.
