In order to readjust the force direction of the support frame back to vertical, it is necessary to add auxiliary devices to the bottom support piles of the support frame. Utility Model Content

[0005] The purpose of the present application is to provide a support frame for a formwork of an ultra-high and large-span roof structure on a soft soil foundation in order to solve the above-mentioned problem of the skewed support frame.

[0006] The technical solution adopted in the present application is as follows: a support frame for a formwork of an ultra-high and large-span roof structure with a soft soil foundation, wherein the side surfaces of the support piles are fixedly connected with a plurality of connecting splints, the side surfaces of the connecting splints are fixedly plugged with connecting shafts, the side surfaces of the connecting shafts are rotatably plugged with connecting rotating blocks, the side surfaces of the connecting rotating blocks are fixedly connected with connecting rods, the connecting rods are rotatably connected with an angle adjustment center axis relative to the side surface of one end of the connecting rotating block, the side surface of the angle adjustment center axis is provided with angle fixing bolts, the angle adjustment center axis is fixedly connected with a sliding intermediate rod relative to the side surface of one end of the connecting rod, the sliding intermediate rod is slidably plugged with an extension sliding rod relative to the side surface of one end of the angle adjustment center axis, and the side surface of one end of the extension sliding rod is fixedly connected with a ground contact pad.

[0007] By adopting the above technical solution, the operator uses multiple connecting splints and connecting shafts on the supporting piles to plug into the connecting rotating blocks, and uses the connecting rotating blocks to connect the connecting rods, the angle adjustment center axis, and the sliding intermediate rod, so that the extended sliding rod and the ground contact pad on the sliding intermediate rod can contact the ground, wherein the angle fixing bolts are used to fix the rotation angle of the angle adjustment center axis, thereby achieving auxiliary support for the supporting piles in other directions.

[0008] The supporting piles serve as the main support structure, and the connecting splints are used as the connecting structure. The connecting shafts thereon serve as connecting components to connect the connecting rotating blocks and the connecting rods. Due to the rotatability between the connecting rotating blocks and the connecting shafts, the operator can adjust the support angle to adapt to the stress conditions of the soft ground.

[0009] The angle adjustment center axis serves as a component connecting the sliding intermediate rod and the connecting rod, and also plays a role in adjusting the angle. However, since the sliding intermediate rod is a component on which the extended sliding rod is inserted, the sliding intermediate rod needs to be adjusted to an angle parallel to the ground. Therefore, the angle adjustment center axis needs to be adjusted. After adjustment, the angle is fixed with the angle fixing bolts to keep the auxiliary support stable.

[0010] The sliding between the extended sliding rod and the sliding intermediate rod can adjust the distance of contact with the ground, and make the ground contact pad contact with the ground, and use the large surface area of ​​the ground contact pad to reduce the pressure and will not sink into the soft soil layer.

[0014] By adopting the above technical solution, the fixed plug-in shaft is driven to be plugged into the fixed hole by using the translation cross bar, so that the extension length of the extended sliding rod is fixed at a certain length, which helps to use the extended sliding rod and the ground contact pad to achieve the support effect after adjustment.

[0015] In a preferred embodiment, a supporting base plate is fixedly connected to the bottom surface of the supporting pile, and a plurality of mounting through holes are formed on the side surface of the supporting base plate.

[0016] By adopting the above technical solution, the supporting base plate is used as the component of the supporting pile that directly contacts the ground surface, wherein the large area of ​​the supporting pile is conducive to reducing the pressure and preventing the supporting pile from sinking into the ground, and the installation through hole is used as the hole for installation.

[0017] In a preferred embodiment, a soil nail is inserted through the hole opened in the installation through hole.

[0018] By adopting the above technical solution, the soil nails are deeply driven into the soil layer, so that the supporting base plate is tightly fixed on the ground surface.

[0019] In a preferred embodiment, a plurality of serial through grooves are fixedly connected to the side surfaces of the support piles, and serial rods are connected to the side surfaces of the serial through grooves.

[0020] By adopting the above technical solution, the series through grooves are used as the main components for connecting the supporting series rods, wherein the series rods connect multiple support piles in series, so that the support piles can be connected in series when supporting soft surfaces, thereby preventing uneven force caused by soft collapse of the surface, thereby causing unstable support.

[0021] In a preferred embodiment, a fastening screw is inserted through a threaded hole opened on the side surface of the serial through groove.

[0022] By adopting the above technical solution, the rod-shaped components connected in series are fastened to the supporting piles by means of fastening screws to prevent loosening.

[0023] In a preferred embodiment, a supporting top plate is fixedly connected to the upper surface of the supporting pile.

[0024] By adopting the above technical solution, the operator uses the supporting top plate as a component that contacts and supports the roof structure.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0026] In this application, the support piles serve as the main support structure, and the connecting splints are used as the connecting structure. The connecting shafts thereon serve as connecting components to connect the connecting rotating blocks and the connecting rods. Due to the rotatability between the connecting rotating blocks and the connecting shafts, the operator can adjust the support angle to adapt to the stress conditions of the soft ground.

[0027] The angle adjustment center axis serves as a component connecting the sliding intermediate rod and the connecting rod, and also plays a role in adjusting the angle. However, since the sliding intermediate rod is a component on which the extended sliding rod is inserted, the sliding intermediate rod needs to be adjusted to an angle parallel to the ground. Therefore, the angle adjustment center axis needs to be adjusted. After adjustment, the angle is fixed with the angle fixing bolts to keep the auxiliary support stable.

[0028] The sliding between the extended sliding rod and the sliding intermediate rod can adjust the distance of contact with the ground, and make the ground contact pad contact with the ground, and use the large surface area of ​​the ground contact pad to reduce the pressure and will not sink into the soft soil layer.

[0037] The operator uses multiple connecting splints 2 and connecting shafts 3 on the supporting pile 1 to plug and connect the rotating block 4, and uses the connecting rotating block 4 to connect the connecting rod 5, the angle adjustment center axis 6, and the sliding intermediate rod 8, so that the extended sliding rod 9 and the ground contact pad 10 on the sliding intermediate rod 8 can contact the ground, and the angle fixing bolt 7 is used to fix the rotation angle of the angle adjustment center axis 6, so as to achieve auxiliary support for the supporting pile 1 in other directions.

[0038] The supporting pile 1 is used as the main supporting structure, and the connecting splint 2 is used as the connecting structure. The connecting shaft 3 thereon is used as a connecting component to connect the connecting rotating block 4 and the connecting rod 5. Due to the rotatability between the connecting rotating block 4 and the connecting shaft 3, the operator can adjust the supporting angle to adapt to the stress conditions of the soft ground.

[0039] Among them, the angle adjustment center axis 6 serves as a component connecting the sliding intermediate rod 8 and the connecting rod 5, and also plays a role in adjusting the angle. However, since the sliding intermediate rod 8 is a component on which the extended sliding rod 9 is inserted, the sliding intermediate rod 8 needs to be adjusted to an angle parallel to the ground. Therefore, the angle adjustment center axis 6 needs to be adjusted. After adjustment, the angle is fixed with the angle fixing bolt 7, so that the auxiliary support remains stable.

[0040] The sliding between the extended sliding rod 9 and the sliding intermediate rod 8 can adjust the distance of contact with the ground, and make the ground contact pad 10 contact with the ground, and use the large surface area of ​​the ground contact pad 10 to reduce the pressure and will not sink into the soft soil layer.

[0041] The side surface of the sliding intermediate rod 8 is fixedly connected with a plurality of bearing upright plates 11, and the side surface of the bearing upright plates 11 is provided with sliding transverse grooves 12. The bearing upright plates 11 and the sliding transverse grooves 12 are used to carry and connect the sliding components, and the sliding components are used to drive the plug-in components.

[0042] The sliding cross groove 12 is slidably plugged with a translation cross bar 13 through the hole groove, and a fixed plug-in shaft 14 is fixedly plugged with the side surface of the translation cross bar 13. A plurality of fixed holes 15 are opened on the side surface of the extended sliding rod 9. The translation cross bar 13 drives the fixed plug-in shaft 14 to be plugged with the fixed hole 15, so that the extension length of the extended sliding rod 9 is fixed at a certain length, which helps to use the extended sliding rod 9 and the ground contact pad 10 to contact the ground after adjustment to achieve the supporting effect.

[0043] The bottom surface of the support pile 1 is fixedly connected with a support base plate 16, and the side surface of the support base plate 16 is provided with a plurality of mounting holes 17. The support base plate 16 is used as a component of the support pile 1 that directly contacts the ground surface, wherein the large area of ​​the support pile 1 is conducive to reducing pressure and preventing the support pile 1 from sinking into the ground, and the mounting holes 17 are used as holes for installation.

[0044] The installation through hole 17 is plugged with a soil nail 18 through the hole provided. The soil nail 18 is deeply inserted into the soil layer so that the support base plate 16 is tightly fixed on the ground surface.

[0045] The side surface of the support pile 1 is fixedly connected with a plurality of serial through grooves 19, and the side surface of the serial through grooves 19 is connected with a serial rod 20. The serial through grooves 19 are used as the main component for connecting and supporting the serial rods 20, wherein the serial rods 20 connect the plurality of support piles 1 in series, so that the support piles 1 can be connected in series when supporting on a soft surface, thereby preventing uneven force caused by soft collapse of the surface, thereby causing unstable support.

[0046] The side surface of the series through slot 19 is inserted with a fastening screw 21 through a threaded hole. The fastening screw 21 is used to fasten the series rod-shaped components and the support pile 1 to prevent loosening.

[0047] The upper surface of the support pile 1 is fixedly connected with a support top plate 22. The operator uses the support top plate 22 as a component that contacts and supports the roof structure.

[0048] The implementation principle of an embodiment of a soft soil foundation ultra-high and large-span roof structure formwork support frame of the present application is: the operator uses multiple connecting splints 2 and connecting shafts 3 on the supporting piles 1 to plug and connect the rotating block 4, and uses the connecting rotating block 4 to connect the connecting rod 5, the angle adjustment center axis 6, and the sliding intermediate rod 8, so that the extended sliding rod 9 and the ground contact pad 10 on the sliding intermediate rod 8 can contact the ground, wherein the angle fixing bolt 7 is used to rotate the angle adjustment center axis 6 to achieve fixation, thereby achieving auxiliary support for the supporting piles 1 in other directions.

[0049] The supporting pile 1 is used as the main supporting structure, and the connecting splint 2 is used as the connecting structure. The connecting shaft 3 thereon is used as a connecting component to connect the connecting rotating block 4 and the connecting rod 5. Due to the rotatability between the connecting rotating block 4 and the connecting shaft 3, the operator can adjust the supporting angle to adapt to the stress conditions of the soft ground.

[0050] Among them, the angle adjustment center axis 6 serves as a component connecting the sliding intermediate rod 8 and the connecting rod 5, and also plays a role in adjusting the angle. However, since the sliding intermediate rod 8 is a component on which the extended sliding rod 9 is inserted, the sliding intermediate rod 8 needs to be adjusted to an angle parallel to the ground. Therefore, the angle adjustment center axis 6 needs to be adjusted. After adjustment, the angle is fixed with the angle fixing bolt 7, so that the auxiliary support remains stable.

[0051] The sliding between the extended sliding rod 9 and the sliding intermediate rod 8 can adjust the distance of contact with the ground, and make the ground contact pad 10 contact with the ground, and use the large surface area of ​​the ground contact pad 10 to reduce the pressure and will not sink into the soft soil layer.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
