Description

Technical Field

[0001] The present application relates to the field of support devices, and in particular, to a support column formwork fixing device. Background Art

[0002] With the rapid development of my country's industry, the demand and scale of industrial plant construction are getting larger and larger. The plant building structure design often adopts a frame structure with large span and large space. At the same time, the air tightness and vibration resistance requirements put forward more stringent requirements on the flatness and verticality of the concrete structure surface. The dust-free requirements during the use of clean plants have cancelled the practice of concrete structure plastering. Generally, epoxy paint is directly applied on the concrete base surface. Therefore, while the clean plant is constructed quickly, the concrete structure must be excellent in one go.

[0003] In existing clean workshops, considering the existence of technical mezzanines, the height of support columns is generally around 6-12 meters. The flatness deviation needs to be kept within 8mm, and the verticality deviation needs to be kept within 10mm. Therefore, it is necessary to use formwork support devices to stably support the support column formwork during construction. However, the existing formwork support devices are difficult to adjust the support height and cannot adapt to the stable support operation of the formwork of support columns of different heights.

[0026] The features and performance of the support column formwork fixing device of the present application are further described in detail below in conjunction with the embodiments.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a support column formwork fixing device for supporting and fixing the formwork 410 on the four outer walls of the support column 400, which includes a bottom frame 100 sleeved on the outside of the bottom of the support column 400 and connected to the ground, four formwork reinforcement plates 200 respectively pressing against the outer walls of the formwork 410 on the four sides of the support column 400, twenty-four formwork support corrugated plates 230 provided between the formwork 410 and the formwork reinforcement plates 200, and four bracket structures 300 corresponding to the formwork reinforcement plates 200;

[0029] The bottom frame 100 includes four frame plates 110 and four connecting plates 120 arranged at intervals along the circumference. A connecting plate 120 is provided between the ends of each two adjacent frame plates 110. The frame plates 110 are provided with telescopic grooves 111 running through both ends thereof. Both ends of the telescopic groove 111 of each frame plate 110 are respectively connected to retractable telescopic plates 130. The adjacent two sides of each connecting plate 120 are respectively provided with connecting grooves 140 for clamping the telescopic plates 130 of two adjacent frame plates 110. The connecting plate 120 is connected to two connecting bolts that pass through the connecting grooves 140 and then connect the telescopic plates 130 of two adjacent frame plates 110. 150, each frame plate 110 is connected to eight fixing bolts 160 for connecting to the ground; twenty-four formwork support ribs 230 are arranged at intervals along the circumference of the support column 400, and the two ends of each formwork support rib 230 respectively press against the inner wall of the formwork reinforcement plate 200 and the outer wall of the formwork 410. The outer wall of each formwork reinforcement plate 200 is provided with twelve fixing columns 210 arranged at intervals along the height direction; a formwork connecting column 240 is provided between the ends of two adjacent formwork reinforcement plates 200, and the formwork connecting column 240 is connected to the two corresponding formwork reinforcement plates 200 by eight reinforcement bolts 250 arranged at intervals along the height direction;

[0030] The four support structures 300 are arranged at intervals along the circumference of the bottom frame 100. The support structure 300 includes an oblique support rod 310 whose bottom is hinged to the bottom frame 100 by a pin shaft and can be rotated along a vertical plane. The top of the oblique support rod 310 is hinged with a support plate 320 that can be rotated along a vertical plane through a rotating shaft. The support plate 320 is connected to the support bolt 330 through a thread. The fixing column 210 is provided with a support hole 220 for connecting the support bolt 330. After the oblique support rod 310 is rotated along the vertical plane, the support plate 320 is arranged horizontally and is detachably connected to a support hole 220 on a fixing column 210 on the corresponding template reinforcement plate 200 through the support bolt 330.

[0031] When the support column template fixing device provided by the embodiment of the present application is used, the bottom frame 100 is first placed on the outside of the bottom of the support column 400 and connected to the ground. Specifically, the four frame plates 110 are respectively placed on the outside of the four sides of the bottom of the support column 400, and a connecting plate 120 is set between the ends of every two adjacent frame plates 110. Then, the telescopic plates 130 connected to the two ends of each frame plate 110 are pulled out and connected to the connecting grooves 140 opened on the corresponding connecting plates 120, and the two connecting bolts 150 are respectively tightened. After passing through the connecting plate 120, connect the telescopic plates 130 in the two adjacent frame plates 110, connect the four frame plates 110 and the four connecting plates 120 into a whole to form the bottom frame 100, then pass the fixing bolts 160 through each frame plate 110 to connect to the ground, and sequentially hang the four formwork reinforcement plates 200 on the outside of the formwork 410 of the four outer walls of the support column 400, and respectively set the twenty-four formwork support corrugated plates 230 between the outer wall of the formwork 410 and the inner wall of the formwork reinforcement plate 200, so that each formwork support corrugated plate 230 is fixed to the outer wall of the formwork 410. The two ends of the plate 230 are respectively pressed against the inner wall of the template reinforcement plate 200 and the outer wall of the template 410, and then the four support structures 300 are used to respectively press and support the four template reinforcement plates 200. Specifically, the oblique support rods 310 of the four support structures 300 are rotated to move the support plates 320 hinged at the top of each oblique support rod 310 to a preset position, and then the support plates 320 are rotated to a horizontal arrangement so that the support bolts 330 connected to the support plates 320 are aligned with the upper support bolts of a fixing column 210 on the corresponding template reinforcement plate 200. The support hole 220 is then rotated to move the support bolt 330 axially to connect to the support hole 220 on the fixing column 210, thereby connecting the support plate 320 and the fixing column 210 into a whole using the support bolt 330, and the four support structures 300 connected by the bottom frame 100 support the four template reinforcement plates 200 to press and support the templates 410 of the four outer walls of the fixed support column 400 through the twenty-four template support corrugated plates 230, thereby ensuring the stability of the template 410 of the outer wall of the support column 400.

[0032] The support column template fixing device provided in the embodiment of the present application is formed by setting four frame plates 110 with adjustable lengths and cooperating with four connecting plates 120 to form a bottom frame 100 that can expand or contract outward to adjust the size, thereby adapting to the template 410 support of support columns 400 of different sizes. At the same time, four bottom-rotating support structures 300 are set to be connected to the bottom frame 100, and fixed columns 210 arranged at intervals along the height direction and support holes 220 provided on the fixed columns 210 are provided on the outer walls of the four template reinforcement plates 200. The support height of the support structure 300 can be easily adjusted and connected and fixed with the support holes 220 on the fixed columns 210 of different heights for support, thereby adapting to the template 410 support of support columns 400 of different heights. In addition, a template support corrugated plate 230 is arranged between the inner wall of the template reinforcement plate 200 and the outer wall of the template 410, and the two ends of each template support corrugated plate 230 respectively press against the inner wall of the template reinforcement plate 200 and the outer wall of the template 410, which can ensure that the supporting force of the template reinforcement plate 200 is evenly transmitted to the outer wall of the template 410 through each template support corrugated plate 230 for pressing and fixing.

[0033] In addition, a template connecting column 240 is provided between the ends of two adjacent template reinforcement plates 200. The template connecting column 240 is respectively connected to the two corresponding template reinforcement plates 200 through eight reinforcement bolts 250 arranged at intervals along the height direction, which can connect the four template reinforcement plates 200 into a whole, ensuring that the four template reinforcement plates 200 stably support each template supporting rib plate 230 to press and fix the outer wall of the template 410.

[0034] Example 2

[0035] like Figure 3 As shown, the embodiment of the present application also provides a support column formwork fixing device, which has roughly the same structure as the support column formwork fixing device provided in Example 1, except that, in this embodiment, each frame plate 110 is threadedly connected to a pressure sleeve 170 corresponding to the oblique support rod 310, and the pressure sleeve 170 is threadedly connected to a pressure rod 180 that presses against the outer wall of the corresponding formwork reinforcement plate 200, and an adjustment sleeve 190 that can move along the pressure rod 180 is threadedly provided on the pressure rod 180, and the top of the adjustment sleeve 190 is threadedly connected to a vertically arranged support sleeve 191, and the support sleeve 191 is threadedly connected to a support rod 192, and the bottom of the support plate 320 is provided with a support groove 321 for being threadedly connected to the support rod 192.

[0036] The support column formwork fixing device provided in the embodiment of the present application can further improve the support stability of the formwork reinforcement plate 200 by setting a pressing sleeve 170 connected to the frame plate 110 by a thread and a pressing rod 180 connected to the pressing sleeve 170 by a thread to press the outer wall of the corresponding formwork reinforcement plate 200. At the same time, the pressing rod 180 is provided with an adjusting sleeve 190 that can move along it through a threaded sleeve, and the top of the adjusting sleeve 190 is connected to a vertically arranged supporting sleeve 191 by a thread, and the supporting sleeve 191 is connected to a supporting rod 192 by a thread, and the bottom of the supporting plate 320 is provided with a supporting groove 321 for being threadedly connected to the supporting rod 192. When the pressing sleeve 170 and the pressing rod 180 press against the corresponding template reinforcement plate 200, the adjusting sleeve 190 is fixedly mounted on the pressing rod 180, and the adjusting sleeve 190 and the support plate 320 are connected to form a whole through the supporting sleeve 191 and the supporting rod 192, so that the supporting sleeve 191 and the supporting rod 192 are used to support the support plate 320, so that the oblique support rod 310, the pressing sleeve 170 and the pressing rod 180, the supporting sleeve 191 and the supporting rod 192 form a stable triangular support system to support the outer wall of the template reinforcement plate 200, ensuring that the template reinforcement plate 200 stably presses each template support corrugated plate 230 to press and fix the outer wall of the template 410.

[0037] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
