DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0036] Please refer to Figures 1 to 12 The present embodiment proposes a building template support device applied to a building template, wherein the building template comprises a bottom template 1 and two groups of first side templates 3 and second side templates 4 standing on the bottom template 1, and the two groups of first side templates 3 and second side templates 4 are connected in an interleaved manner to form a rectangular frame structure, as shown in Figure 5 The bottom template 1 further forms limit slots 36 for the insertion of the two first side templates 3 and second side templates 4. When the two first side templates 3 and second side templates 4 are inserted into the limit slots 36, the two first side templates 3 can be kept stable under the action of the second side templates 4, because stop protrusions are formed on the two sides of the second side templates 4 and extend towards each other, and the two second side templates 4 can be firmly supported on the two ends of the first side templates 3 through the support device arranged on the periphery.

[0037] The support device in the application comprises a first inclined strut 7 and a second inclined strut 10 arranged on the outer wall of each second side formwork 4, the first inclined strut 7 and the second inclined strut 10 are respectively distributed on the two sides of the second side formwork 4 and are connected to form an integral component through a connecting rod 8. The top of the first inclined strut 7 and the second inclined strut 10 is slidably connected with a guide rail 6 fixed in the vertical direction on the outer wall of the second side formwork 4, under the action of the guide rail 6, the first inclined strut 7 and the second inclined strut 10 can be lifted and lowered in the vertical direction, and the first inclined strut 7 and the second inclined strut 10 in the application are directly installed outside the building formwork, which is different from the traditional support device and the building formwork in the split design, and personnel can simultaneously manage and store the first inclined strut 7 and the second inclined strut 10, and the first inclined strut 7 and the second inclined strut 10 can be folded, and the overall space occupied during storage is small.

[0038] Two swing rods 17 are also hinged on the outer wall of the second side formwork 4, and the extension ends of the two swing rods 17 are respectively hinged and connected with the middle parts of the first inclined strut 7 and the second inclined strut 10. When the above scheme is implemented, the rotation of the two swing rods 17 is driven by external force, and the bottom of the first inclined strut 7 and the second inclined strut 10 rotates towards the side away from the second side formwork 4 with the top as the center while the first inclined strut 7 and the second inclined strut 10 move downward in the vertical direction on the guide rail 6, so as to form support for the second side formwork 4.

[0039] When the first inclined strut 7 and the second inclined strut 10 perform the above action, the first sliding support plate 9 and the second sliding support plate 11 inside the bottom formwork 1 synchronously slide to the outside, and finally form a state as shown in Figure 8 In this state, one end of the first inclined strut 7 and the second inclined strut 10 abuts against the outer wall of the second side formwork 4, and the other end abuts against the first sliding support plate 9 and the second sliding support plate 11, the first sliding support plate 9, the first inclined strut 7 and the second side formwork 4 form a triangular structure, so that the second side formwork 4 is in a stable support state. The support device in the application is directly attached to the building formwork, when it is necessary to use the support device to support the building formwork, the first inclined strut 7 and the second inclined strut 10 act, and cooperate with the first sliding support plate 9 and the second sliding support plate 11, so that the support device forms support for the building formwork in a fixed posture each time it is opened. Especially in the scene where the height of the building formwork needs to be adjusted, the support device of the application has more obvious advantages, without the need to increase additional consumables to build the support device, and without the need to adjust the angle of the support device each time. Further, the support device and the building formwork are integrated together, which is convenient to operate when in use, and the first sliding support plate 9 and the second sliding support plate 11 are hidden inside the bottom formwork 1, and the first inclined strut 7 and the second inclined strut 10 are closely attached to the outer wall of the second side formwork 4, which maximally reduces the floor area occupied by the whole device.

[0040] The power source of the first inclined support rod 7 and the second inclined support rod 10 is derived from the swing of the swing rod 17. In order to enable the four swing rods 17 to swing synchronously, two fixed seats 12 are symmetrically bolted on the outer wall of the second side formwork 4 in the horizontal direction, and a gap is reserved between the end faces of the two fixed seats 12 facing each other, and a worm 14 is arranged in the gap. The two ends of the worm 14 are in the shape of a round rod, and small chain wheels 16 are fixedly sleeved on the two ends respectively after penetrating through the fixed seats 12. The worm 14 is rotatably connected with the fixed seats 12 when penetrating through the fixed seats 12. Two lining plates 18 are fixed below the outer wall of the second side formwork 4 corresponding to the small chain wheels 16, and large chain wheels 13 are rotatably installed on the opposite end faces of the two lining plates 18. The transmission connection between the small chain wheels 16 and the corresponding large chain wheels 13 is established through chains 15. The shaft of each large chain wheel 13 is fixedly connected with the corresponding swing rod 17 after penetrating through the lining plate 18. The rotation of the worm 14 drives the small chain wheels 16 at both ends to rotate, and the small chain wheels 16 drive the two large chain wheels 13 on the lining plate 18 to rotate through the chains 15, thereby driving the swing rod 17 to swing around the large chain wheel 13 as the center. When the swing rod 17 swings away from the second side formwork 4, an acting force is applied to the middle part of the first inclined support rod 7 and the second inclined support rod 10, so that the two rods rotate around the top as the center and slide downward relative to the guide rail 6. The first inclined support rod 7 and the second inclined support rod 10 finally move to the state shown in the figure. Figure 8

[0041] In addition, a motor 41 is installed on the outer wall of the second side formwork 4. Since the inside of the entire building formwork contains concrete, in order to avoid the concrete flowing from the edge of the second side formwork 4 to the motor 41 and causing pollution to the motor 41, the motor 41 is covered with a protective shell, and the protective shell is integrally formed with the second side formwork 4. A power shaft 38 is drivingly connected to the output end of the motor 41, and a turbine 43 meshing with the worm 14 is fixedly sleeved on the power shaft 38. The rotation of the power shaft 38 is driven by the motor 41, thereby driving the turbine 43 on the power shaft 38 to rotate. The turbine 43 and the worm 14 mesh to drive the worm 14 to rotate. In the present application, a motor 41 and a turbine 43 can be provided on the outer wall of the second side formwork 4 at the position corresponding to each worm 14 to drive the worm 14 to rotate, but preferably a motor 41 and a turbine 43 are installed on one of the second side formworks 4, and the action of the other group of first inclined support rods 7 and second inclined support rods 10 is realized through a linkage structure, which will be described in detail later.

[0042] Figures 10 to 12 The schematic view of the bottom formwork 1 after being cut three times from top to bottom. First, refer to the attached Figure 10 ​The first big gear disc 46 is rotatably installed on the inner top wall of the bottom template 1, two first sliding support plates 9 are symmetrically distributed with the first big gear disc 46 as the center and are slidably assembled with the bottom template 1, and the side of the two first sliding support plates 9 facing each other is provided with first meshing teeth along the length direction of the first sliding support plates 9, the first meshing teeth being engaged with the first big gear disc 46, and when the first big gear disc 46 rotates, the two first sliding support plates 9 can synchronously slide relative to the bottom template 1. The first big gear disc 46 is engaged with the pinion disc 40 which is symmetrically arranged inside the bottom template 1, and each pinion disc 40 is rotatably connected with the bottom template 1.

[0043] When one of the pinion discs 40 rotates, the first big gear disc 46 can be driven to rotate, in order to realize the synchronous action of the first inclined support rods 7 and the second inclined support rods 10 on both sides of the second side template 4, the two pinion discs 40 in the application are coaxially arranged with the corresponding power shafts 38, the center of the pinion disc 40 is formed with a spline groove 42, and the bottom of the power shaft 38 extends into the spline groove 42 and is connected with the spline 39 matched with the spline groove 42. When the two groups of first side templates 3 and second side templates 4 are inserted into the bottom template 1, the spline 39 at the bottom of the power shaft 38 is inserted into the spline groove 42, when the motor 41 drives the power shaft 38 to rotate, the pinion disc 40 coaxially arranged with the power shaft 38 also synchronously rotates, the pinion disc 40 is engaged with the first big gear disc 46 inside the bottom template 1, the rotation of the first big gear disc 46 not only drives the two first sliding support plates 9 to slide, but also drives the pinion disc 40 on the other side to rotate, the rotation of the power shaft 38 corresponding to the pinion disc 40 drives the worm 14 corresponding to the power shaft 38 to rotate, but since the first inclined support rods 7 and the second inclined support rods 10 on both sides of the building template need to rotate in opposite directions to realize the support of the second side template 4, the rotation direction of the power shaft 38 and the worm 14 on the side without the motor 41 is opposite to the rotation direction of the power shaft 38 and the worm 14 on the side with the motor 41. The above structure constitutes a linkage structure for the synchronous action of the two first inclined support rods 7 and the second inclined support rods 10, by adopting such linkage structure, not only the support operation of the building template can be realized, but also the manufacturing cost and maintenance cost of the device can be reduced, and the trouble of adjusting the starting time and the rotating speed of the two motors 41 is avoided.

[0044] Similarly, in order to realize the synchronous sliding of the two second sliding support plates 11 relative to the bottom template 1, as shown in Figure 12As shown, the second gear plate 52 is rotatably installed on the bottom wall inside the bottom template 1, and two second sliding support plates 11 are centrally symmetrically distributed with the second gear plate 52 as the center and are slidingly guided and assembled with the bottom template 1, and the side of the two second sliding support plates 11 facing each other is provided with second meshing teeth along the length direction of the second sliding support plates 11, which are engaged with the second gear plate 52. By driving the second gear plate 52 to rotate, the two second sliding support plates 11 can be synchronously slid out of the bottom template 1. It should be noted that the first sliding support plate 9 and the second sliding support plate 11 in the present application are all in T-shaped structure, which can maximize the degree of freedom of the two in the bottom template 1, and ensure that they always make linear motion inside the bottom template 1.

[0045] As a preferred embodiment, referring again to Figure 11 and Figure 12 As shown, the inside of the bottom template 1 is divided into two areas by the partition plate 48, wherein the first gear plate 46 is located in the upper area and the second gear plate 52 is located in the lower area. A circular hole penetrating through the two areas is formed at the center of the partition plate 48, and a plurality of third meshing teeth 51 are annularly and equidistantly distributed on the top of the second gear plate 52, all of which are arranged in the vertical direction and extend into the upper area through the circular hole. The bottom of the first gear plate 46 is also annularly and equidistantly provided with a plurality of fourth meshing teeth 47, and all of the fourth meshing teeth 47 are also arranged in the vertical direction. When the first side template 3 and the second side template 4 are inserted into the bottom template 1, the motor 41 drives the pinion plate 40 to rotate, and the pinion plate 40 drives the first gear plate 46 to rotate, and the fourth meshing teeth 47 at the bottom of the first gear plate 46 also rotate synchronously. Four bearing seats 49 are annularly distributed on the partition plate 48, and each bearing seat 49 is connected with a long shaft gear 50 on the side facing the center of the partition plate 48, and the long shaft gear 50 is arranged between the fourth meshing teeth 47 and the third meshing teeth 51 and synchronously engaged with them. When the fourth meshing teeth 47 rotate, they are engaged with the long shaft gear 50, and at the same time, the long shaft gear 50 will also drive the second gear plate 52 to rotate due to the engagement with the third meshing teeth 51, and the rotation directions of the first gear plate 46 and the second gear plate 52 are opposite, so that the two second sliding support plates 11 located in the lower area and the two first sliding support plates 9 located in the upper area are synchronously extended out of the bottom template 1. Since the first sliding support plate 9 and the second sliding support plate 11 on the same side of the second side template 4 are not in the same horizontal plane, the first inclined support rod 7 and the second inclined support rod 10 in the present application are not of the same length, wherein the second inclined support rod 10 is finally supported on the second sliding support plate 11, so the length of the second inclined support rod 10 is greater than that of the first inclined support rod 7, and a avoiding slot 37 is formed on the outer wall of the bottom template 1, and when the second sliding support plate 11 is in the initial state, the bottom thereof extends into the avoiding slot 37.

[0046] Furthermore, since the movements of all the first diagonal braces 7, the first sliding support plate 9, the second diagonal braces 10, and the second sliding support plate 11 in this application are driven by a motor 41, and the motor 41 drives the power shaft 38 to rotate, the turbine 43 sleeved on the power shaft 38 and the spline 39 at its bottom rotate at the same speed. When the worm gear 14 meshes with the turbine 43, the small sprockets 16 connected to its two ends rotate at the same speed as the turbine 43. That is to say, the rotation of the two small sprockets 16 and the small gear disk 40 is consistent. In order to ensure that the first diagonal braces 7 and the second diagonal braces 10 can be smoothly supported on the corresponding first sliding support plate 9 and second sliding support plate 11, this application firstly... The sliding speed relative to the bottom template 1 is controlled, and the rotational speed of the first inclined support rod 7 and the second inclined support rod 10 are also designed. Specific control parameters are: the diameter ratio of the small sprocket 16 to the large sprocket 13 is 1:4, and the diameter ratio of the small gear disk 40 to the first large gear disk 46 is 1:3. By adopting the above structural parameter ratios, the rotational speed of the first inclined support rod 7 and the second inclined support rod 10 is less than the sliding speed of the first sliding support plate 9 and the second sliding support plate 11. Thus, when the first sliding support plate 9 and the second sliding support plate 11 slide, they are always located at the front end of the bent structure of the first inclined support rod 7 and the second inclined support rod 10, ensuring that they can ultimately support the first sliding support plate 9 and the second sliding support plate 11. It should be noted that, assuming the first inclined support rod 7 and the second inclined support rod 10 move to... Figure 8 In the shown state, the distance from the bottom bending structure to the outer wall of the second side template 4 is d. Since the sliding speed of the first sliding support plate 9 and the second sliding support plate 11 is relatively fast, the lengths of the first sliding support plate 9 and the second sliding support plate 11 in this application must be greater than d. Moreover, since the height of the second sliding support plate 11 is lower than that of the first sliding support plate 9, the length of the second diagonal support rod 10 must be greater than that of the first diagonal support rod 7. Similarly, the length of the second sliding support plate 11 must also be greater than that of the first sliding support plate 9.

[0047] Secondly, the shapes of the bottom of the first diagonal brace 7 and the second diagonal brace 10 are designed, such as... Figure 8 As shown, the bottoms of the first diagonal brace 7 and the second diagonal brace 10 are both inclined inward relative to their length direction, forming a bent shape. When the first sliding support plate 9 and the second sliding support plate 11 are fully extended, the first diagonal brace 7 and the second diagonal brace 10 rotate to their maximum angle. At this time, the bent structure at the bottom of both will remain vertical. Moreover, since both are inclined inward, the clearance between the bottom of the first diagonal brace 7 and the second diagonal brace 10 and the ends of the first sliding support plate 9 and the second sliding support plate 11 will be larger than that in a straight line, ensuring that the first diagonal brace 7 and the second sliding support plate 11 can be supported on the corresponding first sliding support plate 9 and the second sliding support plate 11.
