Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a tall formwork support frame. Background Art

[0002] With the acceleration of urbanization and industrialization, construction projects with larger spaces, spans, and loads have emerged. The formwork support systems are also more complex than those of ordinary projects, which are also known as tall formwork projects. Support frames are usually set up during construction to facilitate the construction team's construction operations.

[0003] Existing Figure 1 A tall formwork support frame is shown, including several vertical rods 2 arranged in an array and a working platform 1 installed at the upper end of the vertical rods 2. Adjacent vertical rods 2 are connected by horizontal rods 3. Buckles 4 are installed between the vertical rods 2 and the horizontal rods 3. Several installing diagonal rods 5 are installed between adjacent vertical rods 2. The installing diagonal rods 5 are inclined to fix the adjacent vertical rods 2 together. Buckles 4 are also installed between the installing diagonal rods 5 and the vertical rods 2. The fixed connection between the vertical rods 2 and the installing diagonal rods 5 is completed by the buckles 4.

[0004] During the installation of the support frame, after setting up the vertical rod 2, it is necessary to sequentially fix multiple diagonal rods 5 on the vertical rod 2 through the buckles 4. Since there are a large number of diagonal rods 5 to be installed, a lot of time and energy are required during the installation process, and the installation process is troublesome. Summary of the Invention

[0005] In order to facilitate the installation of the support frame, the present application provides a tall template support frame.

[0008] The mounting rod is provided with a plurality of abutment plates along the vertical direction for the first connecting rod to abut, the abutment plates having a storage state in which they are received in the mounting rod and an abutment state in which they are extended out of the mounting rod, and the abutment plates are provided with abutment components for controlling the abutment plates at adjacent upper ends to change from the storage state to the abutment state when the first connecting rod abuts on the abutment plates and the second connecting rod abuts on the first connecting rod;

[0009] The mounting rod is provided with a plurality of stabilizing rods, a control rod is slidably mounted on the mounting rod, and a plug-in assembly is provided on the mounting rod to control the stabilizing rod to be inserted into the first connecting rod or the second connecting rod when the control rod slides.

[0010] By adopting the above technical solution, the base is fixedly installed on the ground, the mounting rod is fixedly installed on the base through the mounting assembly, and then several first connecting rods are lowered along the mounting rod. When the first connecting rod abuts against the abutting plate at the lower end, the second connecting rod is lowered along the mounting rod until the second connecting rod abuts against the first connecting rod. Under the action of the abutting assembly, the abutting plates at the adjacent upper ends are in an abutting state, which is convenient for the next round of lowering of the first connecting rod and the second connecting rod. When all the first connecting rods and the second connecting rods are installed, the stabilizing rod on the mounting rod can be inserted into the first connecting rod or the second connecting rod through the sliding control rod. Finally, the working platform is installed at the upper end of the mounting rod to complete the installation of the support frame, thereby achieving the effect of facilitating the installation of the bracket mold.

[0011] The cam is provided with a second guide inclined surface for abutting and controlling the connecting plate to slide in the horizontal direction of the mounting rod, and the side panel is provided with a second guide inclined surface for abutting and controlling the connecting plate to slide in the horizontal direction of the mounting rod.

[0012] By adopting the above technical solution, when the second connecting plate abuts against the abutting plate in the abutting state, the abutting block drops, and under the action of the first guide inclined surface, the pushing block slides toward the direction close to the mounting rod until the pushing block abuts against the connecting plate. At this time, under the action of the second guide inclined surface, the limiting block no longer abuts against the abutting plate at the adjacent upper end. At this time, under the action of the elastic block, the abutting plate rotates toward the direction away from the mounting rod until the abutting plate is in the abutting state, thereby achieving the effect of the abutting assembly changing the abutting plate from the storage state to the abutting state.

[0013] Optionally, the stabilizing rod includes a rotating portion and a sliding portion, the rotating portion is provided with an elastic member for controlling the sliding portion to slide in a direction away from a rotation center point of the rotating portion, the first connecting rod is provided with a first plug-in slot for the sliding portion to be snapped into, and the second connecting rod is provided with a second plug-in slot for the sliding portion to be snapped into;

The stabilizing rod is rotatably connected to the mounting rod, and the plug-in gears are arranged at the rotation center of the stabilizing rod.

[0015] By adopting the above technical solution, when the control rod slides in the vertical direction, the rotating part starts to rotate under the action of the plug-in rack and the plug-in gear, and at the same time, the sliding part slides away from the rotating part under the action of the elastic member until the sliding part is inserted into the first plug-in slot or the second plug-in slot.

[0016] Optionally, the elastic member is an abutment spring, and a sliding groove is provided on the rotating part for the sliding part to slide toward or away from the rotation center of the rotating part. One end of the abutment spring abuts against the sliding part, and the other end of the abutment spring abuts against the bottom of the sliding groove.

[0017] By adopting the above technical solution, under the action of the elastic force of the abutting spring, the sliding portion is always subjected to the elastic force from the rotation center, which controls the sliding portion to slide in a direction away from the rotating portion.

[0018] Optionally, a first plug-in rod is provided on the first connecting rod, a second plug-in rod is provided on the second connecting rod, the sliding portion is provided with a mounting slot for inserting the first plug-in rod or the second plug-in rod, and the mounting rod is provided with a pushing member for controlling the first plug-in rod or the second plug-in rod to slide toward the mounting slot when the control rod slides.

[0019] By adopting the above technical solution, when the control rod slides, under the action of the pusher, the first plug rod or the second plug rod can be inserted into the installation slot, thereby enhancing the stability of the sliding part on the first connecting rod or the second connecting rod.

[0020] Optionally, the pushing member is a push block that slides on the mounting rod, and the control rod is provided with a guide surface for the push block to abut and control the push block to slide away from the mounting rod. When the abutment plate is in the abutment state, the first plug-in rod and the second plug-in rod are aligned with the corresponding push blocks.

[0021] By adopting the above technical solution, when the control rod descends, the guide surface drives the push block to slide away from the middle of the installation rod, and the push block pushes the first plug rod or the second plug rod to insert the first plug rod or the second plug rod into the plug slot.

[0022] Optionally, the first connecting rod is provided with a first stabilizing groove for inserting the push block, and the second connecting rod is provided with a second stabilizing groove for inserting the push block. The first stabilizing groove is adapted to the push block, and the second stabilizing groove is adapted to the push block. The side of the push block away from the control rod is provided with a chamfer.

[0023] By adopting the above technical solution, when the first connecting rod or the second connecting rod does not fall completely and correctly into the specified position, the position of the first connecting rod can be adjusted by chamfering and the first stabilizing groove, and the position of the second connecting rod can be adjusted by chamfering and the second stabilizing groove.

[0024] Optionally, the lower groove wall of the rotating groove is an unlocking block, and the unlocking block slides horizontally on the mounting rod. The control rod is provided with an unlocking member that controls the unlocking block to slide toward the mounting rod when the push block extends out of the mounting rod. A receiving groove for receiving the abutment plate is provided at the lower end of the rotating groove, and a reset surface for the mounting rod to abut and control the sliding part to slide toward the rotating part is provided on the sliding part.

[0025] By adopting the above technical solution, when the formwork needs to be dismantled, after the control rod continues to move, under the action of the unlocking member, the unlocking block no longer abuts against the abutment plate. At this time, the first connecting rod and the second connecting rod can drive the abutment plate to continue rotating, and the abutment plate is retracted into the installation rod. At the same time, the stabilizing rod can also be pushed into the storage groove of the second connecting rod at the adjacent upper end. The first connecting rod and the second connecting rod both descend, making it convenient to dismantle the first connecting rod and the second connecting rod.

[0026] Optionally, the unlocking member is an unlocking rope, one end of the unlocking rope is arranged on the control rod, and the other end of the unlocking rope is arranged on the unlocking block.

[0027] By adopting the above technical solution, when the control rod rises, the control rod pulls the unlocking rope to make the unlocking block slide toward the inside of the mounting rod until the unlocking block no longer abuts against the abutting plate.

[0028] Optionally, the mounting assembly includes a mounting block, a clamping block and a clamping spring, the mounting block is arranged on the side wall of the mounting rod, the base is provided with a sliding groove for the mounting block to slide, the clamping block slides on the sliding groove wall, the mounting block is provided with a clamping groove for the clamping block to be inserted, the clamping block is provided with a guide surface for the mounting block to abut and control the clamping block to slide in the direction away from the mounting block, and the clamping spring always gives the clamping block an elastic force to slide toward the bottom of the clamping groove.

[0029] By adopting the above technical solution, the mounting rod drives the mounting block into the base, the mounting block abuts against the guide surface, and the clamping block slides away from the mounting block. When the clamping block is aligned with the clamping groove, the clamping block is inserted into the clamping groove under the action of the elastic force of the clamping spring. At this time, the mounting block is fixed on the base, completing the fixed installation of the mounting rod on the base.

[0030] In summary, this application has at least one of the following beneficial effects:

[0031] 1. When installing the support frame, fix the base on the ground, then fix the mounting rod on the base, slide the first connecting rod and the second connecting rod from top to bottom, and at the same time, the abutment plate can bear the sliding first connecting rod and the second connecting rod, and at the same time, the stabilizing rod can be inserted into the first connecting rod and the second connecting rod, and then slide the control rod to reinforce the fixed connection between the mounting rod, the first connecting rod, the second connecting rod and the stabilizing rod, and finally fix the working platform on the mounting rod to complete the installation of the support frame, so as to achieve the effect of convenient installation of the support frame;

[0032] 2. Continue to slide the control rod so that the unlocking block no longer abuts against the abutment plate.

[0046] Reference Figure 2 and Figure 3 The clamping block 92 is further provided with a guide surface 921. When the mounting block 91 slides vertically along the sliding groove 62, the mounting block 91 abuts against the guide surface 921. At this time, under the action of the guide surface 921, the clamping block 92 slides away from the mounting block 91, and the clamping block 92 can be completely received in the horizontal groove 63. The mounting block 91 continues to slide until the clamping block 92 is aligned with the clamping groove 911. At this time, under the action of the elastic force of the clamping spring 93, the clamping block 92 slides toward the bottom of the clamping groove 911 until the clamping block 92 is inserted into the clamping groove 911. At this time, the mounting block 91 is fixed to the base 6, and the mounting rod 7 is fixed to the base 6 at the same time. In this way, all the mounting rods 7 are inserted into the base 6.

When the control rod 15 descends, the guide surface 151 on the control rod 15 abuts against the pushing block 191, and the pushing block 191 can slide in the direction away from the control rod 15. The pushing block 191 can push the first plug rod 17 or the second plug rod 18 to slide in the direction away from the mounting rod 7 until the first plug rod 17 or the second plug rod 18 can be inserted into the mounting slot 1321.

[0060] Reference Figure 6 and Figure 7 The first connecting rod 81 has a first stabilizing groove 816 for inserting the push block 191, and the second connecting rod 82 has a second stabilizing groove 826 for inserting the push block 191. The first stabilizing groove 816 and the second stabilizing groove 826 mate with the push block 191, and a chamfer 1911 is provided on the side of the push block 191 away from the control rod 15. When the push block 191 slides away from the control rod 15, if the first connecting rod 81 or the second connecting rod 82 deviates and does not fall completely into the designated position, the chamfer 1911 can adjust the position of the first connecting rod 81 or the second connecting rod 82, thereby improving the stability of the bracket mold.

[0061] Reference Figure 6 and Figure 7 The lower groove wall of the rotating groove 701 is the unlocking block 20, and an unlocking groove 708 is provided on the mounting rod 7 for the unlocking block 20 to slide horizontally. A storage groove 709 is provided at the lower end of the rotating groove 701 for the abutment plate 10 to be received. An unlocking member 21 is also installed on the mounting rod 7. The unlocking member 21 is an unlocking rope 211. One end of the unlocking rope 211 is bonded to the control rod 15, and the other end of the unlocking rope 211 is bonded to the unlocking block 20. A rope groove 710 for the unlocking rope 211 to move is provided on the mounting rod 7.

[0062] Reference Figure 6 and Figure 7When the control rod 15 continues to descend, the control rod 15 can pull the unlocking block 20 to slide toward the mounting rod 7 until the unlocking block 20 no longer abuts against the abutment plate 10. At this time, the first connecting rod 81 and the second connecting rod 82 can drive the abutment plate 10 to descend, and the abutment plate 10 can be stored in the storage groove 709. The first connecting rod 81 and the second connecting rod 82 pass through the abutment plate 10 and continue to descend.

[0063] Reference Figure 6 and Figure 7 A reset surface 1322 is provided on the sliding portion 132 for the mounting rod 7 to abut against and control the sliding portion 132 to slide toward the rotating portion 131. When the first connecting rod 81 and the second connecting rod 82 abut against the stabilizing rod 13, under the action of the reset surface 1322, the rotating portion 131 and the sliding portion 132 can be re-entered into the rotating groove 704, and the first connecting rod 81 and the second connecting rod 82 continue to descend through the abutment plate 10.

[0064] Reference Figure 8 A connecting rope 152 is installed on the upper end surface of the control rod 15, and a winding column 711 is installed on the wall of the control groove 705. The connecting rope 152 is wound around the winding column 711 to reduce the occurrence of the control rod 15 falling during work. A connecting groove 11 for the mounting rod 7 to be inserted is opened on the lower end surface of the working platform 1. The working platform 1 is fixed to the mounting rod 7, and a screw or a buckle 4 can be used.

[0065] The implementation principle of a tall formwork support frame in the embodiment of the present application is as follows:

[0066] When installing the support frame, the base 6 is fixed on the ground, and then the mounting rod 7 is controlled to enter the mounting groove 61. The mounting block 91 pushes the clamping block 92 into the horizontal groove 63 until the clamping block 92 is aligned with the clamping groove 911. At this time, under the action of the elastic force of the clamping spring 93, the clamping block 92 is inserted into the mounting block 91, completing the fixed connection of the mounting rod 7 on the base 6.

[0067] Then the first connecting rod 81 and the second connecting rod 82 slide down from top to bottom, and the abutment plate 10 supports the sliding first connecting rod 81, and the second connecting rod 82 abuts the upper end of the first connecting rod 81, and the abutment bar 822 pushes the abutment block 121 down. With the cooperation of the pushing block 122 and the connecting rod, the limiting block 123 no longer abuts on the abutment plate 10 at the adjacent upper end. At this time, the abutment plate 10 changes from the storage state to the abutment state under the action of the elastic block 22, and the abutment plate 10 can be abutted by the first connecting rod 81 of the next round.

[0068] When all the first connecting rods 81 and the second connecting rods 82 are installed, the control rod 15 is lowered. With the cooperation of the plug-in rack 161 and the plug-in gear 162, the stabilizing rod 13 rotates away from the installation rod 7. At the same time, under the action of the elastic force of the abutting spring 141, the sliding portion 132 can be inserted into the first plug-in slot 813 or the second plug-in slot 823.

[0069] The control rod 15 is further lowered. Under the action of the guide surface 151, the push block 191 drives the first plug rod 17 or the second plug rod 18 to be inserted into the installation slot 1321, thereby strengthening the fixed connection between the installation rod 7, the first connecting rod 81, the second connecting rod 82, and the stabilizing rod 13. Then, the connecting rope 152 is wound around the winding column 711, and finally, the work platform 1 is fixedly installed at the upper end of the installation rod 7. The installation of the support frame is completed. Since the installation process only requires moving the installation rod 7, the first connecting rod 81, the second connecting rod 82, and the lowering of the control rod 15, the effect of convenient installation of the support frame is achieved.

[0070] When the support frame needs to be disassembled, the control rod 15 is continued to be lowered so that the unlocking block 20 no longer abuts against the abutment plate 10. The first connecting rod 81 and the second connecting rod 82 can be lowered under the action of gravity, pushing the abutment plate 10 into the installation rod 7. When all the first connecting rods 81 and the second connecting rods 82 fall on the base 6, the effect of facilitating the disassembly of the support frame is achieved.

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
