[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1:

[0038] See also Figure 1-2 and Figure 4A temporary protection device for cast-in-place column corners at a construction site includes a base 1, and also includes: a corner guard plate 2, which is arranged above the base 1 and is composed of two plates hinged to each other, and is used to support and protect the column corner; a fixing mechanism 4, one end of which is arranged on the outer wall of the corner guard plate 2, and the other end is connected to the base 1, and is used to support and limit the movement of the corner guard plate 2; an installation mechanism 5, which is arranged above the base 1, and is used to connect with the fixing mechanism 4 and adjust the position of the fixing mechanism 4 on the base 1. A plurality of mounting holes 17 are provided on the base 1, and the base 1 can be fixed to the ground by bolts and the mounting holes 17. The fixing mechanism 4 includes multiple groups of fixing components, each group of fixing components includes an inner column 41, an outer column 42 and a fixed support seat 43. The two ends of the inner column 41 are respectively connected to the fixed support seat 43 and the outer column 42, and the fixed support seat 43 supports and limits the corner guard plate 2 through the cooperation of the inner column 41 and the outer column 42.

[0039] When used to protect column corners, four devices can be placed, one for each of the four corners of the column. First, base 1 is placed against the column corner, and then base 1 is fixed to the ground using mounting holes 17 and bolts. Next, corner guard 2 is placed against the column corner. By attaching the fixing brackets 43 of fixing mechanism 4 to the outer wall of corner guard 2, corner guard 2 is supported and protected, achieving effective protection. When protecting column corners at different angles, after rotating both sides of corner guard 2 to the corresponding angle, fixing mechanism 4 can be used to adjust the support angle of corner guard 2 by fixing brackets 43. This adjustment can be tailored to the specific usage, offering a wide range of applications, meeting diverse needs, and providing high flexibility and practicality.

[0040] The mounting mechanism 5 can then be used to change the fixed position of the fixing bracket 43 on the base 1. This allows the position of the fixing mechanism 4 to be adjusted according to different column angles and the different mounting heights of the fixing bracket 43 on the corner guard 2. This not only improves the fixing and supporting effect of the fixing mechanism 4 and subsequent fixing bracket 43 on the corner guard 2, thereby improving the support and protection performance of the column corner. Furthermore, by changing the shape of the triangle formed by the corner guard 2, the fixing bracket 43, the fixing mechanism 4, and the mounting mechanism 5, the support and protection performance of the column corner can be adjusted according to different situations, significantly improving the protection effect and quality of the column corner. Finally, the fixed support 43 can be firmly fixed on the corner guard plate 2, thereby stably supporting and protecting the corner guard plate 2, avoiding the current situation that the protection of the column corner by the rubber strip is not stable enough and easy to fall off, and also avoiding the current situation that the protective plate and the column corner are fixed by screws. Not only can this method avoid structural damage to the column corner, but the device also has a stable protection effect on the column corner. By having an external stable and continuous support force for the corner guard plate 2, the protection effect of the column corner is significantly improved, thereby greatly improving the construction quality of the column.

[0041] After use, the device can be disassembled and stored, and then reused to protect other column corners. It can be recycled and reused, which not only avoids waste and saves costs, but also greatly improves the practicality of the device and meets the needs of construction. At the same time, the device is very convenient to transport, move and store, greatly reducing the space occupied, and can be widely used in construction sites and production.

[0042] In this embodiment, preferably, please refer to Figure 4-6 The interior of the base 1 is provided with mutually symmetrical arc-shaped cavities 6, and the inner wall of the arc-shaped cavity 6 is slidably connected to an arc-shaped support rod 7. The end of the arc-shaped support rod 7 away from the arc-shaped cavity 6 is rotatably connected to a support plate 8. When the corner guard 2 is attached to the outer wall of the column corner, after the base 1 is placed, the arc-shaped support rod 7 can be slid along the inner wall of the arc-shaped cavity 6, which will drive the support plate 8 to move. The support plate 8 can rotate around the rotation point with the arc-shaped support rod 7, and finally the support plate 8 is attached to the outer wall of the corner guard 2, which can pre-fix and restrict the outer wall of the corner guard 2 to prevent the corner guard 2 from moving during subsequent operations, and at the same time, it can better limit and support the corner guard 2. External screw holes are opened through the front and rear walls of the support plate 8, and internal screw holes corresponding to the external screw holes are opened on the outer wall of the corner guard 2. The support plate 8 and the corner guard 2 can be fixed together by bolts, which can improve the support stability of the corner guard 2.

[0043] The upper wall of the base 1 is provided with a limiting groove 22 which is communicated with the arc cavity 6, and the upper wall of the arc support rod 7 is threadedly connected with a stud 23, which is used to fix and limit the arc support rod 7 in cooperation with the limiting groove 22, thereby improving the supporting and stabilizing effect of the arc support rod 7 and the support plate 8 on the corner guard plate 2.

[0044] In this embodiment, preferably, please refer to Figure 2 and Figure 4The fixed support 43 includes a support 431, a transmission cavity 432, multiple support plates 433, and multiple transmission assemblies. The outer wall of the support 431 is hinged to one end of the inner column 41. The transmission cavity 432 is opened inside the support 431. The support plates 433 are connected to the transmission assembly to support and protect the corner guard 2. The transmission assembly is located in the transmission cavity 432 and is used to drive the support plates 433 to rotate to adapt to the angle of different column angles. The outer wall of the corner guard 2 is fixedly connected to multiple equidistant stops 21 to limit the movement of the support plates 433. By attaching the support 431 of the fixed support 43 to the outer wall of the corner guard 2, the support 431 can rotate around the hinge of the inner column 41 and be located between adjacent stops 21 on the corner guard 2. The fixed support 43 is then limited by the inner column 41 and the outer column 42, so that the corner guard 2 can be supported and protected, with good protection effect. When protecting column corners at different angles, after the two sides of the corner guard plate 2 are rotated to the corresponding angles, the support plate 433 can be driven to rotate by the transmission component, and then the angle of the support plate 433 can be adjusted. It can be adjusted according to specific usage conditions, has a wide range of applications, meets different needs, has strong flexibility and high practicality.

[0045] In this embodiment, preferably, please refer to Figure 7 The transmission assembly includes a rotating shaft 11, a rotating rod 18, a worm gear 19, and a worm 20. The rotating shaft 11 and the rotating rod 18 are rotatably connected to the upper and lower walls and the front and rear walls of the transmission chamber 432, respectively. The worm gear 19 and the worm 20 are fixedly connected to the outer walls of the rotating shaft 11 and the rotating rod 18, respectively, and the worm gear 19 and the worm 20 are meshed. When protecting column corners of different angles, the rotating rod 18 can be rotated to drive the worm 20 to rotate. The worm 20 will then drive the worm gear 19 meshed with it to rotate, thereby causing the rotating shaft 11 and the support plate 433 to rotate, thereby adjusting the angle of the support plate 433. Since the worm gear 19 and the worm 20 have a self-locking effect, the support plate 433 can be stably protected and can be adjusted according to specific usage conditions.

[0046] The outer wall of the inner column 41 is slidably connected to the inner wall of the outer column 42. The outer wall of the inner column 41 is provided with a plurality of adjustment holes, and the outer wall of the outer column 42 is equipped with fixing bolts that match the adjustment holes. When the fixing bracket 43 moves, it drives the inner column 41 to slide along the inner wall of the outer column 42, causing the inner column 41 to extend outward or retract inward relative to the outer column 42. This ensures that the fixing bracket 43 is always in the optimal support position for the corner guard 2. After adjustment, the fixing bolts and the adjustment holes can be used to secure the inner column 41.

[0047] In this embodiment, preferably, please refer to Figure 2 and Figure 4The mounting mechanism 5 includes a slide rail 51, a slide seat 52, a fastener 53, and a plurality of adjustment holes 54. The slide rail 51 is fixedly connected to the upper end of the base 1, and the slide seat 52 is slidably connected to the slide rail 51. The end of the outer column 42 is hinged to the upper end of the slide seat 52. A plurality of adjustment holes 54 are provided on the side wall of the slide rail 51. The fastener 53 is mounted on the outer wall of the slide seat 52. The fastener 53 of the present invention is a bolt that secures the slide seat 52 by cooperating with the adjustment holes 54. The slide seat 52 can be slid along the slide rail 51, thereby driving the fixing mechanism 4 to move, that is, driving the fixing mechanism 4 to move toward or away from the column corner. Therefore, the position of the fixing mechanism 4 driven by the slide 52 can be adjusted according to different column angles and different installation heights of the fixing support 43 on the corner guard 2, thereby improving the support and protection performance of the column corner. After the adjustment is completed, the slide rail 51 is fixed on the slide rail 51 through the cooperation of the fastener 53 and the adjustment hole 54, so that the bottom position of the fixing mechanism 4 can be fixed. At this time, the fixing mechanism 4 and the installation mechanism 5 can be stably fixed.

[0048] Example 2:

[0049] See also Figure 1-3 Based on the first embodiment, the outer wall of the end of the corner guard 2 is fixedly connected to a connecting plate 19, which is provided with a plurality of connecting holes 10 for fixing two adjacent corner guards 2 together. When it is necessary to protect a higher column corner, if the height of one corner guard 2 is limited, an additional corner guard 2 can be added. The additional corner guard 2 can be placed above the bottom corner guard 2. Bolts can then be passed through the connecting holes 10 on the two connecting plates 19 and secured with nuts. This allows the device to adapt to different heights and other conditions for protecting column corners, further improving its effectiveness. Then, as in the first embodiment, the fixing bracket 43 on the other set of adjustment components can be fixed to the additional corner guard 2 to support the additional corner guard 2, thereby further supporting and protecting the column corner, thus achieving excellent practicality.

[0050] In this embodiment, preferably, please refer to Figure 4-5 A limiting slide groove 22 adapted to the corner guard plate 2 is provided on the upper wall of the base 1 for limiting the movement of the bottom of the corner guard plate 2. By inserting the arc-shaped support rod 7 into the limiting slide groove 22, the movement of the corner guard plate 2 can be further restricted, thereby greatly improving the protective effect of the bottom corner guard plate 2 on the column corner.

[0051] Example 3:

[0052] See also Figure 1-2 and Figure 8-10On the basis of embodiment one, the outer walls of both sides of the corner guard plate 2 are hinged with a first protective sleeve 12 and a second protective sleeve 13 respectively. The first protective sleeve 12 is slidably connected to the connecting plate 2 14. The second protective sleeve 13 is provided with a sliding groove adapted to the connecting plate 2 14. The upper end of the connecting plate 2 14 is provided with a plurality of limiting holes 15. The upper end of the second protective sleeve 13 is provided with a limiting assembly 16, which is used to cooperate with the limiting holes 15 to fix the connecting plate 2 14. The limiting assembly 16 includes a telescopic member 161, a pull block 162 and a limiting rod 163. The telescopic member 161 in the present invention adopts a spring. The two ends of the telescopic member 161 are respectively fixed between the second protective sleeve 13 and the pull block 162. One end of the limiting rod 163 is fixedly connected to the pull block 162, and the other end is movable through the second protective sleeve 13 and can limit the movement of the connecting plate 2 14 by extending into the limiting hole 15.

[0053] After fixing the corner guard 2 around the column corner, flip the first protective sleeve 12 and the second protective sleeve 13 on both sides of the corner guard 2 so that it is in a horizontal state, and then slide the connecting plate 14 along the first protective sleeve 12 and insert it into the sliding groove of the second protective sleeve 13 on the adjacent corner guard 2. When the limiting rod 163 encounters the position of the limiting hole 15, it will drop into the limiting hole 15 through the action of the telescopic member 161. After adjusting the length of the connecting plate 14 entering the second protective sleeve 13, the limiting rod 163 will enter the limiting hole 15 and then fix the connecting plate 14. The outer wall of the column can be further supported and protected by the first protective sleeve 12, the second protective sleeve 13 and the connecting plate 14, which also improves the protection of the column, ensures the quality of subsequent columns, and improves the use effect. When the connecting plate 2 14 needs to be removed, the limiting rod 163 can be driven out of the limiting hole 15 by pulling the pull block 162 upwards. At this time, the connecting plate 2 14 can be removed and separated from the second protective cover 13. The disassembly and assembly are very convenient and simple, and the use effect is good.

[0054] Working Principle: When using this device to protect the corners of a column, four devices can be placed on the four corners of the column. First, the base 1 is placed against the column corner, and then the base 1 is fixed to the ground using the mounting holes 17 and bolts. The corner guard 2 is then placed against the column corner. At this time, the arc-shaped support rod 7 can be slid along the inner wall of the arc cavity 6, which will drive the abutment plate 8 to move. The abutment plate 8 can rotate around the rotation point with the arc-shaped support rod 7, and finally the abutment plate 8 is placed against the outer wall of the corner guard 2, thus pre-fixing and restricting the outer wall of the corner guard 2. By placing the support 431 of the fixed support 43 against the outer wall of the corner guard 2, the support 431 can rotate around the hinge of the inner column 41 and be located between the adjacent blocks 21 on the corner guard 2. The fixed support 43 is then restricted by the inner column 41 and the outer column 42, thus supporting and protecting the corner guard 2. When protecting column corners of different angles, after the two sides of the corner guard plate 2 are rotated to the corresponding angles, the rotating rod 18 can be rotated to drive the worm 20 to rotate, and the worm 20 will drive the worm wheel 19 engaged with it to rotate, thereby causing the rotating shaft 11 and the support plate 433 to rotate, and then the angle of the support plate 433 can be adjusted. Since the worm wheel 19 and the worm 20 have a self-locking effect, the support plate 433 can be stably protected and can be adjusted according to specific usage conditions.

[0055] The slide 52 can then be slid along the slide rail 51, thereby driving the fixing mechanism 4 to move, that is, driving the fixing mechanism 4 to move toward or away from the column corner, thereby adjusting the fixing position of the fixing mechanism 4 on the base 1, improving the support and protection performance of the column corner. After the adjustment is completed, the slide rail 51 is fixed to the slide rail 51 through the cooperation of the fastener 53 and the adjustment hole 54, thereby fixing the bottom position of the fixing mechanism 4. At this time, both the fixing mechanism 4 and the installation mechanism 5 are stably fixed, thereby effectively supporting and protecting the corner guard 2, and significantly improving the protection quality of the column corner. Finally, the fixing support 43 can be firmly fixed to the corner guard 2, thereby providing stable support and protection for the corner guard 2.

[0056] When protection is needed for higher column corners, if the height of one corner guard 2 is limited, an additional corner guard 2 can be added. The additional corner guard 2 can be placed above the lowest corner guard 2 and close to the column corner. Bolts are passed through the connection holes 10 on the two connecting plates 9 and fastened with nuts to secure the additional corner guard 2. Then, similar to the above steps, the fixing brackets 43 on the other set of adjustment components are fixed to the additional corner guard 2 to support the additional corner guard 2.

[0057] After fixing the corner guard 2 around the column corner, flip the first protective sleeve 12 and the second protective sleeve 13 on both sides of the corner guard 2 so that it is in a horizontal state, then slide the connecting plate 2 along the first protective sleeve 12, and then insert the end of the connecting plate 2 14 into the slide groove of the second protective sleeve 13 on the adjacent corner guard 2. When the connecting plate 2 14 contacts the limiting rod 163, it will drive it to rise and stretch the telescopic member 161 at the same time. When the limiting rod 163 encounters the position of the limiting hole 15, it will descend into the limiting hole 15 through the action of the telescopic member 161. After adjusting the length of the connecting plate 2 14 entering the second protective sleeve 13 so that the limiting hole 15 corresponds to the position of the telescopic member 161, the limiting rod 163 will enter the limiting hole 15 and then fix the connecting plate 2 14, which can further support and protect the outer wall of the column.
