Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a support frame for cone-shaped hopper construction. Background Technology

[0002] With the development of the construction industry, storage buildings have become increasingly diverse, such as grain silos, coal silos, and iron ore silos. These buildings typically have conical hoppers at the bottom for discharging materials. Materials are stored inside the silo and then unloaded onto vehicles, ships, or other transport vehicles for use in various regions. Generally, these conical hoppers are integrated with the main silo body. A horizontal structural layer is installed at the bottom of the silo to connect the conical hoppers to the main silo body. To ensure airtightness, the conical hoppers are usually made of reinforced concrete. To facilitate material discharge, the conical hoppers are often designed as inverted cones, which is more conducive to the pouring of materials. However, the inverted cone shape of reinforced concrete is quite special and brings considerable difficulties to its construction, which can easily slow down the construction schedule of the silo.

[0003] One of the difficulties in the construction process is how to ensure the stability of the accuracy during the construction of the cone bucket, that is, how to ensure the consistency of the tilt angle of the cone bucket sidewall and the stability of the construction process. Summary of the Invention

[0004] The technical problem this invention aims to solve is: how to improve the construction accuracy and stability of concrete silo cone buckets. To address this problem, this invention provides a cone bucket construction support for use with a formwork system. The support includes multiple concentrically arranged support frames in a ring structure. Each support frame includes multiple uprights, circumferential rods, and an adjustable top support. The uprights are evenly distributed circumferentially, with their tops connected to the formwork system to provide support for the inclined formwork system. The bottoms of the uprights are connected to the adjustable top support, which is grounded and height-adjustable, and supports the uprights. A circumferential rod is provided between two adjacent uprights within the same support frame, with both ends of the circumferential rod rotatably connected to two adjacent uprights within the same support frame.

[0005] The spacing between adjacent support frames is equal; the number of uprights in each support frame is the same and they are arranged sequentially in the radial direction, and the extension lines of the lines connecting corresponding uprights in adjacent support frames all point towards the axis of the support frame;

[0006] In the adjacent support frame, multiple radial rods are evenly distributed in the vertical direction between two adjacent uprights in the radial direction, and the two ends of the radial rods are respectively rotatably connected to the two adjacent uprights in the radial direction in the vertical plane.

[0007] Preferably, the upright has a plurality of first rotating parts corresponding to the radial rod in the vertical direction, and each first rotating part includes two rotating hinge supports symmetrically arranged in the radial direction of the support frame; one end of the radial rod is fixedly connected to a first snap-fit ​​device, which is rotatably connected to the rotating hinge support on the upright in the vertical plane, and the other end of the radial rod is rotatably connected to the corresponding rotating hinge support on the corresponding upright in the adjacent support frame in the vertical plane.

[0008] Preferably, the rotating hinge support includes a limiting body, which has a limiting groove with an opening facing the radial direction of the support frame. The limiting groove passes through the upper and lower ends of the limiting body in a vertical direction. The first snap-fit ​​device and one end of the radial rod are each provided with a plug-in short plate corresponding to the limiting groove. The rotating hinge support also includes a horizontally arranged limiting round rod, which passes through the limiting body and the plug-in short plate located in the limiting groove in sequence.

[0009] Preferably, the first snap-fit ​​device includes a snap-fit ​​body, the snap-fit ​​body is provided with a snap-fit ​​slot, the inner wall of the snap-fit ​​slot is provided with an internal thread, one end of the radial rod is provided with an external thread corresponding to the internal thread, and the radial rod is threadedly connected to the snap-fit ​​body.

[0010] Preferably, the snap-fit ​​slot is a semi-circular slot with an opening on one side. The snap-fit ​​body has symmetrically arranged protruding plates on one side of the snap-fit ​​slot opening. Multiple snap-fit ​​rods are arranged side by side on the protruding plates. The snap-fit ​​rods are used to limit the radial rods to prevent the ends of the radial rods from disengaging from the snap-fit ​​slot. One end of the snap-fit ​​rod is connected to a connecting plate that abuts against the protruding plate, and the other end of the snap-fit ​​rod is connected to a snap-fit ​​bolt that abuts against the protruding plate.

[0011] Preferably, the upright has a plurality of second rotating parts in the vertical direction corresponding to the circumferential rod, and each second rotating part includes two rotating balls symmetrically arranged with the axis of the upright as the line of symmetry.

[0012] One end of the circumferential rod is fixedly connected to a second snap-fit ​​device, which is rotatably connected to the rotating ball on the upright. The other end of the circumferential rod is rotatably connected to the corresponding rotating ball on the adjacent upright in the same support frame.

[0013] Preferably, the included angle between the two rotating spheres in the same second rotating component is less than 180 degrees; both the second snap-fit ​​device and the circumferential rod can rotate freely around the rotating spheres at multiple angles. Preferably, the bottom of the upright is provided with a short steel pipe, and the short steel pipe is fixedly connected to multiple uprights in the adjacent support frame through a snap-fit ​​structure.

[0014] Preferably, the radial rod is inclined, and the inclination angle of the radial rod is the same as the inclination angle of the inclined surface of the cone to be constructed.

[0015] Preferably, the inner side of the bracket is provided with a supporting body, and the outer side of the bracket is provided with a flat formwork support frame. The supporting body and the flat formwork support frame are respectively used to support the inner and outer parts of the formwork system. The flat formwork support frame is fixedly connected to the outermost support frame of the bracket, and the supporting body is rotatably connected to the formwork system to adjust the construction tilt angle of the formwork system.

[0016] Compared with the prior art, the cone-shaped construction support provided in this embodiment of the invention has the following advantages:

[0017] This invention employs multiple annular support frames based on the tilt angle and height of the cone-shaped formwork. The spacing between adjacent support frames is equal, and the tops of the uprights within each support frame are connected to the formwork system to provide support for the tilted system. The bottoms of the uprights are connected to adjustable top supports, ensuring stable support between the bottom of the upright and the ground. Multiple support frames provide more comprehensive and stable support for the formwork system, enabling more stable casting of the cone-shaped formwork with higher precision. This avoids issues such as uneven local stress distribution within the formwork system, which can lead to variations in the tilt angle of the cast cone or instability in the casting angle. Furthermore, the circumferential and radial rods better connect the uprights within the entire support system into a unified whole, resulting in better and more stable overall stress distribution and improved support for the formwork system.

[0024] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] It should be noted that in this article, "circumferential direction" refers to the circumferential direction of the bottom surface of the construction target cone; "radial direction" refers to the direction of the diameter extension of the bottom surface of the construction target cone.

[0026] like Figure 1 and Figure 2 As shown, a preferred embodiment of the present invention provides a support frame for cone bucket construction, which is used to cooperate with the formwork system 2 to construct cone buckets. It includes multiple support frames 11 arranged concentrically in a ring structure. Each support frame 11 includes multiple uprights 111, circumferential rods 112, and adjustable top supports 113. The multiple uprights 111 are evenly distributed in sequence along the circumference. The top of the uprights 111 is connected to the formwork system 2 to provide support for the inclined formwork system 2. The bottom of the uprights 111 is connected to the adjustable top supports 113. The adjustable top supports 113 are set on the ground and their height is adjustable. The adjustable top supports 113 are used to support the uprights 111. A circumferential rod 112 is provided between two adjacent uprights 111 in the same support frame 11. The two ends of the circumferential rod 112 are respectively rotatably connected to two adjacent uprights 111 in the same support frame 11.

[0027] The spacing between adjacent support frames 11 is equal; the number of uprights 111 in each support frame 11 is the same and they are arranged in the radial direction in sequence, and the extension lines of the lines connecting the corresponding uprights 111 in adjacent support frames 11 all face the axis of the support frame 11.

[0028] In the adjacent support frame 11, a plurality of radial rods 12 are evenly distributed in the vertical direction between two adjacent uprights 111 in the radial direction. The two ends of the radial rods 12 are respectively rotatably connected to the two adjacent uprights 111 in the radial direction in the vertical plane.

[0029] Specifically, during the concrete cone pouring process, the formwork system 2 can be tilted first. The height and tilt angle of the formwork system 2 are determined beforehand, ensuring that its tilt angle matches the designed cone tilt angle. Then, the support frame 1 is constructed to provide support for the formwork system 2. This prevents problems such as the formwork system 2 becoming unsupported and unable to bear the weight of the concrete during pouring, which could lead to bending or changes in its tilt angle. This ensures high precision and stability during the cone pouring process. Furthermore, the height and angle of the formwork system 2 must be fixed between the construction poles 111 according to the cone pouring requirements. After the height and angle of the template system 2 are fixed, all the uprights 111 are installed according to the preset positions and spacing. The top of the uprights 111 is installed with the top of the template system 2. All the uprights 111 in the same support frame 11 are connected to the template system 2 and are all on the same annular surface and at the same height. The angle of the line connecting the tops of the corresponding uprights 111 in adjacent support frames 11 is the same as the tilt angle of the template. The angle and height of the template system 2 are different depending on the position and angle of the cone to be constructed. At this time, uprights 111 of different heights can be used to meet the actual construction needs. The dimensions of the uprights 111 are designed and produced according to the same modular dimensions to adapt to the needs of different radial heights of the cone and ensure the high precision requirements of the production process. Once the tops of all uprights 111 are connected to the formwork system 2, the circumferential rods 112 and radial rods 12 can be installed. The radial rods 12 can only rotate relative to the uprights 111 in the vertical plane, and regardless of their rotation, their extension lines always point towards and intersect the center line of the cone. The radial rods 12 can connect different support frames 11 into a single unit, resulting in better and more stable force distribution. Similarly, the circumferential rods 112 are rotatably connected to the uprights 111, accommodating the need for uprights 111 of different densities within the same support frame 11. A higher density upright 111 results in a larger angle between the circumferential rods 112 and the uprights 111, and vice versa. The circumferential rods 112 can connect multiple uprights within the same support frame 11. The 111 sections are connected to form a whole, resulting in better and more stable force distribution. Furthermore, the circumferential rod 112 and the upright rod 111 are not limited to rotation within the water surface; in fact, they are freely rotatable. This structure allows the circumferential rod 112 to adapt to more complex and varied environments and meet more usage requirements. The aforementioned circumferential rod 112 and radial rod 12 configuration allows for the adjustment of the height of the outermost upright rod 111 alone to meet the construction support requirements of cones with different curvatures, tilt angles, and height positions. Adjusting the height of the outermost upright rod 111 changes the angle between the radial rod 12 and the upright rod 111, meaning that regardless of the cone's curvature, the tilt angle requirements of the cone can be better met.Once the circumferential rod 112 and radial rod 12 are connected, the height of the adjustable top support 113 at the bottom of the upright 111 can be adjusted to meet the support requirements of different uprights 111. Specifically, since all uprights 111 use the same modular dimensions, but the height of the top of the uprights 111 in different support frames 11 is different, the height difference between the bottom of the uprights 111 and the ground is also different. In this invention, by setting an adjustable top support 113 at the bottom of the uprights 111, the bottom of the uprights 111 can be more stably in contact with the ground, maintaining the stability of the top position of the uprights 111 in different support frames 11, avoiding problems such as deviation in the height position of the top of the uprights 111, and thus ensuring the stability and high precision of the formwork system 2 during the pouring of the cone. The adjustable top support 113 mainly consists of a screw and a support plate threadedly connected to the screw. The position of the support plate relative to the screw can be adjusted by rotation. The bottom of the upright 111 abuts against the support plate. By rotating the support plate, the bottom of the screw can contact the ground, providing stable support for the upright 111. This eliminates the height difference between the bottom of the upright 111 and the ground at different heights, allowing the upright 111 to adapt to more complex ground environments. This is a relatively common structure in existing technology. Furthermore, the adjustable top support 113 has removable and replaceable wooden beams at its bottom. Multiple wooden beams of varying sizes are provided and can be placed between the adjustable top support 113 and the ground. When the adjustable range of the top support 113 is limited, the diverse sizes of the wooden beams better help the top support 113 support the upright 111 on a level surface. The wooden beams also increase the contact area between the adjustable top support 113 and the ground, thereby reducing the pressure on the ground from the adjustable top support 113 and allowing for more stable support of the upright 111 on a level surface. It should also be noted that the top of the upright 111 can be rotatably connected to the formwork system 2, facilitating adjustment of the tilt angle of the formwork system 2. Even when the formwork system 2 is at different tilt angles, the upright 111 remains vertical, providing stable support for the formwork system 2.

[0030] like Figure 1 and Figure 3 As shown, in some embodiments, the upright 111 is provided with a plurality of first rotating members corresponding to the radial rod 12 in the vertical direction. Each first rotating member includes two rotating hinge supports 114 symmetrically arranged in the radial direction of the support frame 11. One end of the radial rod 12 is fixedly connected to a first snap-fit ​​device 13, which is rotatably connected to the rotating hinge support 114 on the upright 111 in the vertical plane. The other end of the radial rod 12 is rotatably connected to the corresponding rotating hinge support 114 on the corresponding upright 111 in the adjacent support frame 11 in the vertical plane.

[0031] Specifically, the spacing between adjacent first rotating components on the upright 111 also conforms to the modular dimensions, facilitating industrialized production and installation and improving production and installation efficiency. Two rotating hinge supports 114 are symmetrically arranged on both sides of the upright 111, and the line connecting the two rotating hinge supports 114 passes through the axis of the support frame 11. One of these rotating hinge supports 114 is directly connected to the radial rod 12, while the other is connected to the radial rod 12 via the first snap-fit ​​device 13. Through the first rotating component, the radial rod 12, and the first snap-fit ​​device 13, adjacent support frames 11 can be connected as a whole to bear force, resulting in a better and more stable force-bearing structure. It is understandable that the first rotating component on the upright 111 of the innermost and outermost support frames 11 may include only one rotating hinge support 114, or it may include two, but only one of them will be used to connect to the radial rod 12. Furthermore, the radial rod 12 can rotate in the vertical plane. Compared with a fixed connection structure, when facing cones of different heights and inclination angles to be constructed, the height difference at the top of adjacent support frames 11 and the spacing between adjacent support frames 11 can be adjusted. At this time, the inclination angle of the radial rod 12, which is rotatably connected to the upright 111, can also be adjusted more conveniently according to construction needs. Its construction adjustment is more convenient, and it can also play a good role in lateral constraint on the upright 111, limiting the lateral movement of the upright 111.

[0032] like Figure 3 As shown, in some embodiments, the rotating hinge support 114 includes a limiting body 1141, the limiting body 1141 is provided with a limiting groove 1142 with an opening facing the radial direction of the support frame 11, the limiting groove 1142 passes through the upper and lower ends of the limiting body 1141 in the vertical direction, and one end of the first snap-fit ​​device 13 and the radial rod 12 are provided with a plug-in short plate corresponding to the limiting groove 1142; the rotating hinge support 114 also includes a horizontally arranged limiting round rod 1143, the limiting round rod 1143 passes through the limiting body 1141 and the plug-in short plate located in the limiting groove 1142 in sequence.

[0033] Specifically, the openings of the limiting grooves 1142 on the symmetrically arranged rotating hinge supports 114 on the same upright 111 are oriented in opposite directions, and their extension lines are both directed towards and intersect the axis of the support frame 11. This facilitates the installation of the radial rod 12 and its rotation in the vertical plane. Furthermore, the limiting grooves 1142 extend vertically through the upper and lower ends of the limiting body 1141, providing greater space for the rotation of the radial rod 12. This allows for a wider range of adjustable tilt angles for the radial rod 12, satisfying a greater variety of tilt angles. The construction requirements of the cone bucket are as follows: the limiting round rod 1143 is set as the rotation axis of the radial rod 12. The limiting round rod 1143 can limit the first locking device 13 and the radial rod 12, preventing the first locking device 13 and the radial rod 12 from disengaging from the limiting groove 1142 during rotation. The limiting round rod 1143 can also restrict the radial rod 12 to rotate only in the vertical plane and not in other inclined planes, ensuring the stability of the radial rod 12 during the rotation adjustment of the tilt angle and the stability under force.

[0034] like Figure 3 and Figure 4 As shown, in some embodiments, the first snap-fit ​​device 13 includes a snap-fit ​​body 131, the snap-fit ​​body 131 is provided with a snap-fit ​​slot 132, the inner wall of the snap-fit ​​slot 132 is provided with an internal thread 1321, one end of the radial rod 12 is provided with an external thread corresponding to the internal thread 1321, and the radial rod 12 is threadedly connected to the snap-fit ​​body 131.

[0035] Specifically, the radial rod 12 is threadedly engaged with the snap-fit ​​body 131. Rotating the radial rod 12 ensures a stable connection between it and the snap-fit ​​body 131. It also allows adjustment of the position of the radial rod 12 relative to the snap-fit ​​body 131, enabling better connection between both ends of the radial rod 12 and the uprights 111. This is particularly important when the uprights 111 are relatively tall and prone to tilting at the top. The first snap-fit ​​device 13 ensures the consistency of the position between the radial rod 12 and the snap-fit ​​body 131, effectively guaranteeing the parallelism of the uprights 111 in adjacent support frames 11. This ensures the uprights 111 are vertically aligned, making the overall structure of the bracket 1 more stable. Furthermore, the threaded structure facilitates the disassembly and installation of the radial rod 12. In other embodiments, other structures such as hooks, buckles, or teeth can be used, as long as they prevent the radial rod 12 from easily tilting to the side, ensuring consistent vertical spacing between corresponding uprights 111 in adjacent support frames 11, resulting in a more stable and rational structure.

[0036] like Figure 4As shown, in some embodiments, the snap-fit ​​slot 132 is a semi-circular slot with an opening on one side. The snap-fit ​​body 131 is symmetrically provided with a protruding plate 133 on the opening side of the snap-fit ​​slot 132. Multiple snap-fit ​​rods 1331 are arranged side by side on the protruding plate 133. The snap-fit ​​rods 1331 are used to limit the radial rod 12 to prevent the end of the radial rod 12 from disengaging from the snap-fit ​​slot 132. One end of the snap-fit ​​rod 1331 is connected to a connecting plate 1332 that abuts against the protruding plate 133, and the other end of the snap-fit ​​rod 1331 is connected to a snap-fit ​​bolt 1333 that abuts against the protruding plate 133.

[0037] Specifically, this part of the structure is a further detail of the snap-fit ​​body 131. The snap-fit ​​slot 132 has a semi-circular opening on one side, which makes it easier and more intuitive to see the position of the radial rod 12 relative to the snap-fit ​​body 131. Especially when the snap-fit ​​body 131 has a scale along the axis of the snap-fit ​​slot, the position of the radial rod 12 relative to the snap-fit ​​body 131 can be adjusted more accurately. The snap-fit ​​rod 1331 restricts the radial rod 12 within the snap-fit ​​slot 132, preventing the radial rod 12 from detaching or shifting during use. The snap-fit ​​rod 1331 and the snap-fit ​​slot 132 restrict the five degrees of freedom of the radial rod 12, so that the radial rod 12 can be stably and firmly connected to the snap-fit ​​body 131. The connecting plate 1332 and the snap-fit ​​bolt 1333 are provided to facilitate the installation and restrict the position of the snap-fit ​​rod 1331, preventing the snap-fit ​​rod 1331 from loosening.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, the upright 111 is provided with a plurality of second rotating members in the vertical direction corresponding to the circumferential rod 112, and each second rotating member includes two circumferential balls 115 symmetrically arranged with the axis of the upright 111 as the line of symmetry.

[0039] One end of the circumferential rod 112 is fixedly connected to a second snap-fit ​​device 14, which is rotatably connected to a rotating ball 115 on the upright 111. The other end of the circumferential rod 112 is rotatably connected to the corresponding rotating ball 115 on the adjacent upright 111 in the same support frame 11.

[0040] Specifically, the second snap-fit ​​device 14 and the circumferential rod 112 are provided with groove structures corresponding to the rotating ball 115. The ends of the second snap-fit ​​device 14 and the circumferential rod 112 are rotatably connected to the rotating ball 115 through the groove structures, thereby forming a ring-shaped support frame 11. The rotating ball 115 on the upright 111 is symmetrically arranged with the axis of the upright 111 as the line of symmetry to facilitate the installation of the circumferential rod 112, so that the circumferential rod 112 can be connected with the upright 111 to form a ring structure. The structure of the second snap-fit ​​device 14 is the same as that of the first snap-fit ​​device 13. The specific structure of the first snap-fit ​​device 13 can be referred to, or structures such as snap teeth and buckles can be used.

[0041] In some embodiments, the included angle between the two rotating balls 115 in the same second rotating member is less than 180 degrees; the second snap-fit ​​device 14 and the circumferential rod 112 can both rotate freely around the rotating balls 115 at multiple angles.

[0042] Specifically, the included angle between the two rotating balls 115 in the same second rotating component is related to the number of uprights 111. Specifically, the included angle α between the two rotating balls 115 is (n-2)*180°÷n, where n is the number of uprights 111 in a support frame 11. The included angle between the two rotating balls 115 is less than 180 degrees, and they are not horizontally arranged. This allows the circumferential rod 112 to better cooperate with the uprights 111 to form a ring-shaped support frame 11. In a secondary option, the second rotating component can adopt a rotating hinge support 114 as in the first rotating component. The included angle between the two rotating hinge supports in the second rotating component is also less than 180 degrees. Furthermore, in some embodiments, the first and second rotating components are staggered in height, while in other embodiments, multiple first and second rotating components are correspondingly provided, and the corresponding first and second rotating components are at the same height.

[0043] like Figure 1 As shown, in some embodiments, the bottom of the upright 111 is provided with a short steel pipe, and the short steel pipe is fixedly connected to multiple uprights 111 in the adjacent support frame 11 by a snap-fit ​​structure.

[0044] Specifically, since the radial rods 12 between the uprights 111 are all inclined, it is inevitable that the distance between the nodes connecting some uprights 111 and the radial rods 12 at the bottom of the uprights 111 and the ground is too large, which can easily cause local instability at the bottom of the uprights 111. Therefore, short steel pipes 15 are set at the bottom of the uprights 111. The short steel pipes 15 are connected to multiple uprights 111 by fasteners, making the structure of the entire support 1 more stable and reliable.

[0045] like Figure 1As shown, in some embodiments, the radial rod 12 is inclined, and the inclination angle of the radial rod 12 is the same as the inclination angle of the inclined surface of the cone to be constructed; the circumferential rod 112 is horizontal. The inclined setting of the radial rod 12 is due to the inclined setting of the top of the upright 111. The inclination angle of the radial rod 12 is also consistent with the inclination angle of the cone to be constructed. Since the upright 111 is designed with the same modular size for height, the height interval between the radial rods 12 also meets the same modular size requirement. The inclined setting of the radial rod 12 can meet the needs of industrial production and can also adapt to the construction needs of cones with more different inclination angles. That is, the inclination angle of the radial rod 12 can change with the angle of the cone to be constructed, meeting more construction needs.

[0046] like Figure 1 As shown, in some embodiments, the inner side of the support 1 is provided with a support body 3, and the outer side of the support 1 is provided with a flat formwork support 4. The support body 3 and the flat formwork support 4 are respectively used to support the inner and outer parts of the formwork system 2. The flat formwork support 4 is fixedly connected to the outermost support frame 11 of the support 1, and the support body 3 is rotatably connected to the formwork system 2 to adjust the construction tilt angle of the formwork system 2.

[0047] The flat formwork support 4 and the support body 3 are both pre-set according to the construction position of the cone bucket and the construction progress of the silo. When it is necessary to construct the cone bucket, one end of the formwork system 2 is first rotatably connected to the support body 3, and the other end is overlapped and fixed to the flat formwork support 4. The height of the end of the formwork system 2 near the support body 3 is lower than the height of the end near the flat formwork support 4. The flat formwork support 4 and the support body 3 can provide support for both ends of the formwork system 2 and adjust the tilt angle of the formwork system 2, while the middle part of the formwork system 2 is more comprehensively and stably supported by the bracket 1.

[0048] In summary, this embodiment of the invention provides a support frame 1 for cone bucket construction, which is equipped with multiple annular support frames 11 according to the tilt angle and height of the cone bucket. The spacing between adjacent support frames 11 is equal, and the top of the uprights 111 in the support frame 11 is connected to the template system 2 to provide support for the tilted template system 2. The bottom of the uprights 111 is connected to an adjustable top support 113 with adjustable height. The adjustable top support 113 allows the bottom of the uprights 111 to form a stable support with the ground. The multiple support frames 11 can achieve more comprehensive and stable support for the template system 2, so that the template system 2 can cast the cone bucket more stably and with higher casting accuracy. It avoids the problem of changes in the tilt angle of the cast cone bucket and instability of the casting angle caused by local unbalanced force on the template system 2. The setting of the circumferential rods 112 and the radial rods 12 can better connect the uprights 111 in the entire support frame 1 into a whole, and the overall force of the support frame 1 is better and more stable, which can better support the template system 2.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
