Formwork is a key step in independent column construction, and the performance of the formwork device has a decisive impact on the independent column's molding quality, construction efficiency, and construction safety.

[0003] During the construction of existing wine-making workshop columns, most independent columns are constructed using traditional formwork devices, which have a relatively simple and crude connection structure for adjacent formwork frames. It is common to directly connect adjacent formwork frames through bolts. Although this connection method can fix the formwork frames to a certain extent, in actual construction, the bolt connection method requires the use of tools such as wrenches during installation and disassembly, which is cumbersome and reduces construction efficiency.

The sizes of independent columns in different projects vary, and traditional connection structures are difficult to quickly adapt to size changes. It is often necessary to prepare formwork components of various specifications, which increases material management costs and construction difficulty. In view of this, we propose a formwork protection device for independent column construction. Summary of the Invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The specific embodiments of the present invention are described in detail below in conjunction with the drawings in the specification.

[0036] like Figure 1 、 Figure 4 and Figure 6 As shown, a formwork protection device for independent column construction includes multiple vertically stacked formwork frames 1, a limit assembly, multiple installation sleeves 7, and two locking assemblies fixedly connected to the inner walls of the installation sleeves 7;

[0037] The limiting assembly is arranged between the butt ends of two adjacent mold frames 1, and the limiting assembly includes two symmetrically arranged transverse support plates 4, two symmetrically arranged longitudinal support plates 5, and an adjusting tooth plate 11 fixedly connected to the outer walls of the transverse support plates 4 and the longitudinal support plates 5. The longitudinal support plates 5 are located below the transverse support plates 4 and are arranged perpendicularly to the transverse support plates 4.

[0038] Multiple mounting sleeves 7 are arranged at the intersection of the transverse support plate 4 and the longitudinal support plate 5. Sliding holes 8 are respectively opened at both ends of the mounting sleeves 7. The ends of the transverse support plate 4 and the longitudinal support plate 5 pass through the sliding holes 8 and are slidably connected thereto. The adjusting tooth plates 11 respectively pass through the sliding holes 8 and are slidably connected thereto. The inner walls of the sliding holes 8 are each provided with an extension hole 9.

[0039] The locking assembly is used to fasten the transverse support plate 4 and the longitudinal support plate 5 to the mounting sleeve 7 .

[0040] By sliding the transverse support plate 4 and the longitudinal support plate 5 in the sliding hole 8 of the mounting sleeve 7 and cooperating with the engagement of the adjusting tooth plate 11 and the adjusting gear 13, the coverage range of the stepless adjustment limit assembly is realized to adapt to independent columns of different cross-sectional sizes. This design can match the changes in column size without replacing parts, reducing spare parts inventory.

[0041] The crisscross structure formed by the combination of the two transverse support plates 4 and the two longitudinal support plates 5 and the design of the mounting sleeve 7, the locking assembly and the limiting assembly replace the traditional integral steel hoop to achieve continuous adjustment.

[0042] In this embodiment, Figure 1-Figure 3 As shown, each mold frame 1 has a first flange 2 protruding outward near the top on two opposite first side surfaces, and a second flange 3 protruding outward near the bottom on two opposite second side surfaces; the outer walls of the horizontal support plate 4 and the longitudinal support plate 5 are both provided with a first card groove 6, and the longitudinal support plate 5 is snap-fitted with the corresponding first flange 2 through the first card groove 6, and the horizontal support plate 4 is snap-fitted with the corresponding second flange 3 through the first card groove 6.

[0043] The first flange 2 and the second flange 3 of the mold frame 1 provide a positioning structure for connecting adjacent mold frames 1. When the mold frames 1 are stacked, the first flange 2 and the second flange 3 cooperate with each other to quickly align the mold frames 1, reducing the alignment time during installation. At the same time, it enhances the stability of the connection between adjacent mold frames 1 and prevents the mold frames 1 from being misaligned during the construction process such as pouring concrete.

[0044] The first slots 6 of the transverse support plate 4 and the longitudinal support plate 5 are engaged with the first flange 2 and the second flange 3 of the mold frame 1, further strengthening the connection stability between the limit assembly and the mold frame 1. The clamping method is fast to install and can ensure the relative position of the transverse support plate 4, the longitudinal support plate 5 and the mold frame 1 is stable when adjusting the limit assembly, facilitating subsequent adjustment and tightening operations.

[0045] The stepped nesting design of the first flange 2, the second flange 3, the transverse support plate 4, the longitudinal support plate 5 and the first slot 6 on the flange of the mold frame 1 ensures automatic alignment of the upper and lower mold frames 1 when stacked, avoids casting defects caused by misalignment, and can reduce verticality deviation.

[0046] In this embodiment, Figures 4-10 As shown, the locking assembly includes a shaft support plate 10, the end of which is fixedly connected to the outer wall of the mounting sleeve 7, the inner wall of the shaft support plate 10 is rotatably connected to a support sleeve 12, the outer wall of the support sleeve 12 is fixedly connected to an adjusting gear 13, the adjusting gear 13 passes through the outer hole 9 and extends into the sliding hole 8, and the adjusting gear 13 is engaged with the corresponding adjusting tooth plate 11.

[0047] A limiting tooth groove 14 is provided at the top of the support sleeve 12, and the locking assembly also includes a fixed plate 30, the end of which is fixedly connected to the outer wall of the mounting sleeve 7, and the inner wall of the fixed plate 30 is rotatably connected to the connecting shaft 15, and the inner wall of the connecting shaft 15 is threadedly connected to the adjusting screw 16.

[0048] A movable hole 20 is provided on the outer wall of the connecting shaft 15, and two second slots 21 are provided on the top of the inner wall of the movable hole 20. A slide plate 22 is slidably connected to the inner wall of the movable hole 20, and blocks 23 are fixedly connected at both ends of the slide plate 22. The blocks 23 are slidably connected to the corresponding second slots 21 respectively, and the top of the adjusting screw 16 extends into the movable hole 20.

[0049] The outer wall of the connecting shaft 15 is sleeved with a sliding limit gear 19 , the inner wall of the limit gear 19 is fixedly connected to the two clamping blocks 23 , and the limit gear 19 is engaged with the limit tooth groove 14 and can slide along the inner wall of the limit tooth groove 14 .

[0050] The outer wall of the connecting shaft 15 is fixedly connected to a supporting ring 18, and two sliding rods 24 are fixedly connected to the top of the supporting ring 18. The outer walls of the sliding rods 24 are fixedly connected to the limiting rings 26. The tops of the sliding rods 24 pass through the corresponding blocking blocks 23 and are slidably connected thereto. The outer walls of the sliding rods 24 are sleeved with springs 25, and the inner walls of the two second card grooves 21 are fixedly connected to fixing blocks 27. The bottoms of the fixing blocks 27 are fixedly connected to the corresponding sliding rods 24, respectively. One end of the spring 25 is fixedly connected to the blocking block 23, and the other end of the spring 25 is fixedly connected to the supporting ring 18.

[0051] The meshing pre-tightening of the adjusting gear 13 and the adjusting tooth plate 11 forms a primary locking mechanism; the spring 25 drives the limiting gear 19 to automatically engage and lock with the limiting tooth groove 14, combined with the fine-tuning alignment of the worm wheel 17 and the worm 29, to form a secondary locking mechanism. This structural design can achieve a double anti-loosening effect and improve anti-vibration performance.

[0052] The locking assembly also includes a worm wheel 17 and a worm 29. The worm wheel 17 is sleeved on the connecting shaft 15 and fixedly connected thereto. Both ends of the worm 29 are rotatably connected to two support blocks 28. The ends of the support blocks 28 are respectively fixedly connected to the mounting sleeve 7, and the worm 29 is engaged with the worm wheel 17.

[0053] The locking assembly uses an adjusting tooth plate 11, an adjusting gear 13, a limiting gear 19, a limiting tooth groove 14, a worm wheel 17 and a worm 29, which can achieve fine-tuning and positioning, and is convenient for quick locking with one hand. This design can improve construction efficiency and reduce the time of high-altitude operations.

[0054] In this embodiment, Figure 11 and Figure 12 As shown, the mold frame 1 includes two transverse baffles 101 and two longitudinal baffles 102. The side walls of the two transverse baffles 101 and the two longitudinal baffles 102 are both provided with beveled edges 104. The transverse baffles 101 and the longitudinal baffles 102 are tightly fitted together through the beveled edges 104 and are perpendicular to each other.

[0055] The two horizontal baffles 101 are fixedly connected to the limiting clip 103 at the position near the bottom on the relatively far side, and the two longitudinal baffles 102 are also fixedly connected to the limiting clip 103 at the position near the top on the relatively far side. A right-angled bend is formed at both ends of the limiting clip 103, and docking grooves 105 are formed between the right-angled bend and the corresponding horizontal baffle 101, as well as between the right-angled bend and the longitudinal baffle 102. The two sides of the horizontal baffle 101 and the longitudinal baffle 102 are respectively engaged with the inner walls of the corresponding docking grooves 105.

[0056] In some embodiments, the adjusting screw 16 can be replaced with an extrusion rod structure provided with a spring. The two ends of the spring are fixedly connected to the end of the extrusion rod and the connecting shaft 15 respectively. The extrusion rod passes through the connecting shaft 15 and is slidably connected thereto. The end of the connecting shaft 15 extends into the movable hole 20. During the size adjustment process, the extrusion rod can be pressed to squeeze the slide plate 22 through the end of the extrusion rod, thereby moving the limit gear 19 out from the inner wall of the limit tooth groove 14.

[0057] During the installation process, after the transverse support plates 4 and the longitudinal support plates 5 fix the two transverse baffles 101, the two longitudinal baffles 102 can be inserted into the docking grooves 105 on both sides of the transverse baffles 101 from above to achieve rapid assembly of the mold frame 1.

[0058] Working principle: When supporting the formwork for independent column construction, multiple formwork frames 1 are stacked vertically from bottom to top, and the first flanges 2 and second flanges 3 on the multiple formwork frames 1 are placed on the same side to preliminarily position adjacent formwork frames 1.

[0059] A crisscross frame composed of two transverse support plates 4 and two longitudinal support plates 5 is placed on the connection between the upper and lower mold frames 1 , and the transverse support plates 4 and the longitudinal support plates 5 are respectively connected to the corresponding first flange 2 and second flange 3 through the first slots 6 .

[0060] When the spacing between adjacent mold frames 1 needs to be adjusted to accommodate independent columns of different sizes, the corresponding transverse support plates 4 and longitudinal support plates 5 are pulled to drive the installation sleeves 7 to move respectively, thereby adjusting according to the size of the column.

[0061] After the adjustment is completed, rotate the adjusting screw 16 to move the top end of the adjusting screw 16 out of the movable hole 20. At this time, when the limit gear 19 corresponds to the limit tooth groove 14 below, under the tension of the spring 25, the limit gear 19 drives the clamping block 23 to slide downward along the slide rod 24 and the second clamping groove 21, so that the limit gear 19 quickly slides into the limit tooth groove 14, and the support sleeve 12 is limited and fixed by the limit gear 19, thereby locking the mounting sleeve 7 on the corresponding horizontal support plate 4 and longitudinal support plate 5.

[0062] When the limiting gear 19 does not correspond to the limiting tooth groove 14 below, by rotating the worm 29, the worm 29 drives the worm wheel 17 to rotate, the worm wheel 17 drives the connecting shaft 15 to rotate, and the connecting shaft 15 drives the limiting gear 19 to rotate, so that the limiting gear 19 corresponds to the limiting tooth groove 14, and the two are quickly connected.

[0063] During disassembly, the screw 16 is adjusted in the reverse direction, and the adjusting screw 16 pushes the slide plate 22 upward. The slide plate 22 drives the limit gear 19 to move upward through the block 23, so that the limit gear 19 slides out of the limit tooth groove 14, thereby releasing the fixation of the mounting sleeve 7, and the horizontal support plate 4 and the longitudinal support plate 5 can be moved, and the mold frame 1 can be easily disassembled.

[0064] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
