[0001] The invention relates to the technical field of building construction, in particular to a building construction supporting device. Background Art

[0002] Building construction refers to production activities during the implementation phase of engineering construction, and is the construction process of various types of buildings. When it is necessary to support the template for cantilever panels (such as balcony panels, awnings, eaves panels, bay windows, etc.) during building construction, such components are cantilever components, and the thickness of the panels is mostly thin at the cantilever end and thick at the support end, so the template support generally has a certain inclination angle. At present, there are two situations for the installation and support of the cantilever panel template. One is when there is no supporting structure at the bottom, and a tripod with an inclined structure is generally used. The tripod frame is assembled and fixed to the wall with bolts; the other is when there is a supporting structure at the bottom, and the template is supported on the lower supporting structure. The inclination angle of the template is adjusted by adjusting the length of the template pillar, which is time-consuming and labor-intensive, and it is not convenient to adjust according to the angle requirements of the cantilever panel template. It is also not convenient for later demoulding and bracket disassembly and recycling.

[0017] Specifically, two second hinge seats 31 are provided at the lower end of the mounting plate 3, and the upper end of the first hinge rod 210 and the upper end of the second hinge rod 44 are both hinged to the second hinge seats 31 through the corresponding axes.

[0018] Specifically, the mounting plate 3 is provided with a plurality of threaded holes 32. The plurality of threaded holes 32 provided on the mounting plate 3 facilitate the installation of the cantilever plate template and the disassembly and recycling of the template.

[0019] Specifically, two third hinge seats 12 are further provided on the base 1, and the transmission shaft 22 passes through the third hinge seats 12 in sequence. The two third hinge seats 12 are used to stably support the rotation of the two third hinge seats 12.

[0020] Specifically, a plurality of positioning holes 13 are equidistantly arranged at the edge of the base 1. The stability of the support device is ensured by driving pins into the positioning holes 13 on the base 1 and fixing it to the support structure or assembling it to the tripod on the wall through bolts, thereby ensuring the stability of the entire support device.

[0021] Specifically, the inner part of the telescopic outer tube 26 is symmetrically provided with guide grooves 261, and the two ends of the telescopic inner tube 27 are symmetrically provided with guide bars 272, and the guide bars 272 are correspondingly clamped in the guide grooves 261. The telescopic outer tube 26 and the telescopic inner tube 27 are limited by the guide grooves 261 and the guide bars 272, so that the telescopic inner tube 27 can be driven to rotate synchronously during the rotation of the telescopic outer tube 26.

[0022] Specifically, the second bevel gear 25 and the third bevel gear 271 are of the same model, and the first bevel gear 24 and the fourth bevel gear 291 are of the same model. It is ensured that the second bevel gear 25 rotates around the first bevel gear 24, which is different from the fixed one, and drives the fourth bevel gear 291 to rotate at the same angle when rotating synchronously with the third bevel gear 271, and the second bevel gear 25 connecting shaft drives the connecting rod 231 and the telescopic outer rod 23 to flip in the opposite direction of the fourth bevel gear 291 rotating through the first hinge rod 210 and the cross groove 2111, so as to ensure that the mounting surface of the mounting plate 3 is in a square state, and the flipping process ensures that the mounting plate 3 is installed in an inclined square state, so that it is more convenient for the hydraulic cylinder 28 to lift and lower according to the height requirement of the lifting plate.

[0023] When using, first Figure 7As shown, it is the vertical state of the supporting device. The first step is to install the pick plate template, place the pick plate template on the mounting plate 3, and install the pick plate template on the mounting plate 3 through a plurality of locking bolts. Then, the handle 431 is turned to drive the screw rod 43 to rotate, thereby driving the cross moving block 41 to move along the cross groove 2111, and the mounting plate 3 is lifted by the second hinged rod 44 hinged on the cross moving block 41, so as to adjust the inclination angle of the mounting plate 3. Then the power supply is connected to turn on the stepper motor 21, and the stepper motor 21 drives the transmission shaft 22 to rotate 90 degrees counterclockwise. At the same time, the transmission shaft 22 drives the fixedly connected telescopic outer rod 23 to rotate counterclockwise, and synchronously drives the connecting shaft 251 and the second bevel gear 25 to rotate counterclockwise through the fixedly connected connecting rod 231. At this time, the second bevel gear 25 rotates around the first bevel gear 24 which is fixed differently, and the rotation direction is counterclockwise from the tooth surface direction. The rotation of the second bevel gear 25 drives the telescopic outer tube 26 and the telescopic inner tube 27 to rotate synchronously, thereby realizing the counterclockwise rotation of the third bevel gear 271 at the upper end of the telescopic inner tube 27, which in turn drives The fourth bevel gear 291 that is in dynamic meshing connection synchronously rotates 90 degrees clockwise. Since the second bevel gear 25 and the third bevel gear 271 are of the same model, and the first bevel gear 24 and the fourth bevel gear 291 are of the same model, the second bevel gear 25 flips counterclockwise, causing the mounting plate 3 to deviate at an angle. The third bevel gear 271 drives the fourth bevel gear 291 to rotate clockwise, and the fourth bevel gear 291 rotates through the rotating shaft 29 to drive the first hinge rod 210 and the upper L-shaped frame 211 to rotate clockwise, thereby achieving the angle compensation of the synchronous clockwise rotation process of the mounting plate 3, and always ensuring that the mounting plate 3 and the pick plate template thereon are in an inclined square state. Then, the hydraulic cylinder 28 is started to lift the lower L-shaped frame 2321, and the telescopic inner rod 232 and the telescopic inner tube 27 are simultaneously extended until the cantilever plate template is raised to the required height, and the template can be poured; After casting and forming, the hydraulic cylinder 28 drives the piston rod to shrink and demould, and then the stepper motor 21 is started to rotate in the opposite direction to retract the entire supporting device. The operation is simple and convenient for recycling.
