Description

Technical Field

[0001] This invention relates to the field of building construction safety protection technology, specifically to a device and construction method for installing safety belts and ropes on structural columns without damaging them. Background Technology

[0002] During the construction of buildings or structures, construction workers inevitably need to perform tasks such as masonry, formwork, door and window installation, plastering, and other miscellaneous work near the structural edges. For example, when working at heights indoors, such as building infill walls between structural columns, safety belts must be worn to prevent workers from falling and ensure their safety. The safety belts must be securely and reliably fixed. However, when using embedded hooks in interior wall construction, there are problems such as difficulty in setting up safety belt hooks or anchor points, limited placement after installation, and the need for pre-embedding or creating openings in the structure. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a device and construction method for installing safety belt ropes on structural columns without damaging them.

[0004] The specific technical solution is as follows:

[0005] A device for installing a safety belt lanyard on a structural column without damage includes two clamping components, one of which is disposed on a structural column and the other of which is disposed on a opposite structural column, with the safety belt lanyard disposed between the two clamping components.

[0006] The clamping assembly includes a support plate and a first clamping plate, a second clamping plate, a first adjusting component, and a second adjusting component disposed on the support plate;

[0007] The bearing plate is arranged across one side of the structural column, and the first clamping plate abuts against the side of the structural column where the two structural columns are close to each other, and the second clamping plate abuts against the side of the structural column where the two structural columns are far apart.

[0008] The first adjusting component is used to adjust the position of the first clamping plate. When the safety belt rope is under tension, the second adjusting component generates a force that brings the second clamping plate closer to the structural column.

[0009] Optionally, the first adjusting component includes a threaded rod and two nuts. The bearing plate has a first elongated groove aligned with the length direction of the bearing plate. The first clamping plate has a through hole. The threaded rod passes through the through hole and the first elongated groove. The two nuts are threaded onto the threaded rod to fix the first clamping plate.

[0010] Optionally, a second elongated groove is provided on the support plate, which is aligned with the length direction of the support plate, and the push rod and pull rod are rotatably connected to both sides of the second elongated groove;

[0011] The push rod is rotatably connected to the bearing plate at its midpoint. The push rod has a buffer groove for one end to slide in the second elongated groove. The other end of the push rod is close to the structural column and fixedly connected to the second clamping plate. The pull rod is rotatably connected to the bearing plate at its midpoint. The pull rod has a sliding groove for one end to slide in the second elongated groove. The other end of the pull rod is connected to the safety belt rope.

[0012] The fastener passes through the sliding groove, the buffer groove, and the second elongated groove, and the fastener connects the push rod, the pull rod, and the bearing plate together.

[0013] Optionally, the tie rod can be configured as a straight rod.

[0014] Optionally, the push rod includes a first rod and a second rod fixedly connected to the first rod, and the angle between the first rod and the second rod is an obtuse angle.

[0015] Optionally, the end of the pull rod is provided with a pull ring, and the safety belt rope is fixed to the pull ring.

[0016] Optionally, a rubber pad is provided on the side of the second clamping plate near the structural column.

[0017] A construction method for a device for installing safety belt ropes on structural columns without damaging them includes the following steps:

[0018] S1. The first clamping plate and the bearing plate are connected and assembled through the first elongated groove;

[0019] S2. On the structural columns on both sides of the wall to be built at the construction site, the initial installation height can be set at 3 meters. Adjust the position of the first clamping plate and nut through the first long slot so that the size of the device is consistent with the structural column. Then tighten the nut. At this time, the device is initially attached to the three sides of the structural column and is suspended on the structural column under the action of friction.

[0020] S3. After the height of the clamping components on the two structural columns is adjusted, the safety belt rope is hung through the hole on the pull ring. Turnbuckles can be installed to adjust the tightness of the rope.

[0021] S4. Tighten the safety belt rope using turnbuckles. After the rope is under tension, it will pull the pull ring. Under the pull of the pull ring, the pull rod will rotate around the center of the pull rod, thereby pushing the fixing part. After the fixing part moves, it will pull the end of the push rod. After the end of the push rod is under tension, it will rotate around the center of the push rod, causing the second clamping plate to squeeze against the structural column once, thereby clamping the structural column.

[0022] After the wall construction at S5 and 3 meters is completed, this device can be installed at heights of 5 meters, 7 meters, etc., in sequence according to S1 to S4, so as to meet the construction safety requirements for installation.

[0023] S6. After the subsequent construction processes such as wall and plastering are completed, when it is necessary to remove this device, loosen the taut safety belt rope. After the pulling force of the pull ring disappears, the pushing force on the second clamping plate will also disappear. This device is suspended on the structural column by the friction between the second clamping plate and the first clamping plate. After releasing the second long slot, this device can be removed.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] During wall construction, after the safety belt rope is tightened, the pull ring on the pull rod is pulled, causing the pull rod to rotate around the second pivot, pushing the fixing part to move within the second groove. Since both the push rod and the end of the pull rod are fixed to the fixing part, the push rod is also pulled while the fixing part is moving. Under the action of the buffer groove, the push rod rotates around the first pivot. At this time, the second clamping plate generates a thrust towards the structural column, squeezing the rubber pad. Thus, the entire device is clamped to the structural column by the cooperation of the second clamping plate and the first clamping plate under the thrust of the push rod. This solves the problem of pre-embedding the safety belt hanging point or damaging the structural opening during conventional wall construction. It can also be set before wall construction, without the need for pre-embedding or damaging pre-embedding on the structure. In addition, the safety belt rope can be flexibly pulled at different heights of the structural column according to the construction progress. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0033] The device for installing safety belt ropes on non-destructive structural columns provided in this invention is described in reference to... Figure 1-3 ,include:

[0034] Two clamping components, one clamping component is located on a structural column, and the other clamping component is located on another opposite structural column. The safety belt lanyard 1 is located between the two clamping components.

[0035] The clamping assembly includes a support plate 2 and a first clamping plate 3, a second clamping plate 4, a first adjusting component 5, and a second adjusting component 6 disposed on the support plate 2;

[0036] The bearing plate 2 is set across one side of the structural column, and the first clamping plate 3 abuts against the side of the structural column where the two structural columns are close to each other, and the second clamping plate 4 abuts against the side of the structural column where the two structural columns are far apart.

[0037] The first adjusting component 5 is used to adjust the position of the first clamping plate 3. When the safety belt rope 1 is under tension, the second adjusting component 6 generates a force that brings the second clamping plate 4 closer to the structural column.

[0038] During wall construction, the bearing plate 2 is first placed against the structural column. The position of the first clamping plate 3 is adjusted using the first adjusting component 5 according to the column dimensions, ensuring a tight fit. The friction between the first clamping plate 3 and the structural column is adjusted using the second adjusting component 6, allowing the device to be suspended above the column. After installing and adjusting the devices on the two structural columns to suitable heights using the above method, the safety belt rope 1 is pulled. When the safety belt rope 1 is tightened, the second clamping plate 4 experiences a pushing force towards the structural column, causing the entire device to clamp the structural column under the action of the first clamping plate 3 and the second clamping plate 4. Compared to conventional methods of hanging safety belts, where the hanging height and position are limited by the location of the hanging point, this device allows for flexible installation of the safety belt rope 1 at different heights of the structural column according to the construction progress. Theoretically, within the height of the structural column, the safety belt rope 1 can be adjusted at will to meet the needs of different construction stages.

[0039] The first adjusting component 5 includes a threaded rod and two nuts. The bearing plate 2 has a first elongated groove 20 that is aligned with the length direction of the bearing plate 2. The first clamping plate 3 has a through hole 30. The threaded rod passes through the through hole 30 and the first elongated groove 20. The two nuts are threaded onto the threaded rod to fix the first clamping plate 3. In this way, the threaded rod can slide within the first elongated groove 20 to adjust the structure column of different sizes, and it is also convenient to carry out construction under actual working conditions.

[0040] Specifically, the second adjustment component 6 includes a push rod 61, a pull rod 62, and a fixing component 63; a second elongated groove 21 with the same length direction as the support plate 2 is provided on the support plate 2, and the push rod 61 and the pull rod 62 are respectively rotatably connected to both sides of the second elongated groove 21;

[0041] A first rotating shaft 611 is rotatably connected at the midpoint of the push rod 61. The first rotating shaft 611 is fixedly connected to the bearing plate 2. The push rod 61 has a buffer groove 610 for one end of the push rod 61 to slide in the second elongated groove 21. The other end of the push rod 61 is close to the structural column and fixedly connected to the second clamping plate 4. A second rotating shaft 621 is rotatably connected at the midpoint of the pull rod 62. The second rotating shaft 621 is fixedly connected to the bearing plate 2. The pull rod 62 has a sliding groove 620 for one end of the pull rod 62 to slide in the second elongated groove 21. The other end of the pull rod 62 is connected to the safety belt rope 1.

[0042] The fastener 63 is inserted into the sliding groove 620, the buffer groove 610 and the second elongated groove 21. The fastener 63 can be a bolt and a nut. The bolt and nut are used together to connect the push rod 61, the pull rod 62 and the bearing plate 2 together.

[0043] In addition, a rubber pad 41 is provided on the side of the second clamping plate 4 near the structural column. The rubber pad 41 is made of elastic rubber material, which has good wear resistance and high elasticity, and can make the first clamping plate 3 clamp the structural column more firmly.

[0044] The end of the lever 62 is provided with a pull ring 622, and the safety belt rope 1 is tightened and fixed to the pull ring 622 by means of turnbuckles or the like.

[0045] While the safety belt rope 1 is tightened, the pull ring 622 on the pull rod 62 is pulled, causing the pull rod 62 to rotate about the second pivot 621, pushing the fixing member 63 to move within the second groove. Since the ends of the push rod 61 and the pull rod 62 are both fixed to the fixing member 63, the push rod 61 is also pulled while the fixing member 63 is moving. Under the action of the buffer groove 610, the push rod 61 rotates about the first pivot 611. At this time, the second clamping plate 4 generates a pushing force towards the structural column, squeezing the rubber pad 41, thereby making the entire... The device, under the thrust of the push rod 61, clamps the structural column with the cooperation of the second clamping plate 4 and the first clamping plate 3, thus achieving stable fixation of the entire device to the structural column. Theoretically, the greater the tension on the safety belt rope 1, the greater the thrust on the second clamping plate 4, and the tighter the device will self-lock with the structural column. This solves the problem of pre-embedding the safety belt hanging point or damaging the structural opening during conventional wall construction. This device can be set before wall construction, without the need for pre-embedding or damaging pre-embedding on the structure.

[0046] The pull rod 62 is designed as a straight rod, which can transfer the tension of the safety belt rope to the other end of the pull rod 62. The force at the other end of the pull rod 62 is opposite to and parallel to the tension at the end of the pull rod 62 with the safety belt rope.

[0047] The push rod 61 includes a first rod 612 and a second rod 613 fixedly connected to the first rod 612. The angle between the first rod 612 and the second rod 613 is an obtuse angle. After the force on the push rod 61 is transmitted to the second clamping plate 4, the second clamping plate 4 can be moved closer to the inside of the structural column, thereby clamping the structural column more stably.

[0048] The construction method for the device for installing safety belt ropes on non-destructive structural columns provided by the present invention includes the following steps:

[0049] S1. The first clamping plate 3 and the bearing plate 2 are connected and assembled through the first elongated groove 20;

[0050] S2. On the structural columns on both sides of the wall to be built at the construction site, the initial installation height can be set at 3 meters. By adjusting the position of the first clamping plate 3 and the nut on the first long slot 20, the size of the device is consistent with the structural column. Then tighten the nut. At this time, the device is initially attached to the three sides of the structural column and is suspended on the structural column under the action of friction.

[0051] S3. After the height of the clamping components on the two structural columns is adjusted, the safety belt rope 1 is hung through the hole on the pull ring 622. A turnbuckle can be installed to adjust the tightness of the safety belt rope 1.

[0052] S4. Tighten the safety belt rope 1 using turnbuckles. After the rope is under force, it will pull the pull ring 622. Under the pulling force of the pull ring 622, the pull rod 62 rotates around the center of the pull rod 62, thereby pushing the fixing part 63. After the fixing part 63 moves, it pulls the end of the push rod 61. After the end of the push rod 61 is under tension, it will rotate around the center of the push rod 61, causing the second clamping plate 4 to squeeze against the structural column once, thereby hugging the structural column.

[0053] After the wall construction at S5 and 3 meters is completed, this device can be installed at heights of 5 meters, 7 meters, etc., in sequence according to S1 to S4, so as to meet the construction safety requirements for installation.

[0054] S6. After the subsequent construction processes such as wall and plastering are completed, when it is necessary to remove this device, loosen the taut safety belt rope 1. After the pulling force of the pull ring 622 disappears, the pushing force on the second clamping plate 4 will also disappear. This device is suspended above the structural column by the friction between the second clamping plate 4 and the first clamping plate 3. After the second long groove 21 is released, this device can be removed.

[0055] Conventional methods of pre-embedding and drilling safety belt attachment points require cutting and repairing these points after construction. Using this method avoids the need for structural treatment and repair after construction, reducing treatment and repair costs and eliminating the safety hazard of workers having nowhere to hang their safety belts during treatment and repair.

[0056] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
