Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular, to a reusable edge protection railing clamp. Background Technology

[0002] With the development of construction engineering, high-rise and super high-rise buildings are becoming increasingly common, and the safety issues of vertical openings and edges at construction sites are becoming more and more prominent. Safety protection for edge openings must be arranged in sync with the building floors, but the sides of openings or edges are often smooth vertical walls or columns, without specific locations for installing guardrails.

[0003] Traditionally, expansion bolts are used to directly fix the guardrails to the concrete. However, drilling holes to embed the bolts and installing the guardrails often requires multiple people working together; moreover, expansion bolts are a one-time material and cannot be reused, and subsequent removal is difficult. In addition, secondary repairs are required on the holes in the concrete wall, making the operation cumbersome and consuming a lot of materials and labor. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a reusable edge protection railing clamp.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A reusable edge protection railing clamp includes a connecting rod, on which a fixed clamping plate and a movable clamping plate are provided along the axial direction. A driving member is provided on the connecting rod, which can drive the movable clamping plate to move along the axial direction. A connecting sleeve for the railing to pass through is also provided on the connecting rod.

[0007] Preferably, the connecting rod is a screw, and the driving component includes a hand-tightening nut screwed onto the connecting rod.

[0008] Preferably, both the fixed clamping plate and the movable clamping plate are L-shaped plates, and the openings of the fixed clamping plate and the movable clamping plate face each other.

[0009] Preferably, the connecting sleeve has a connecting hole, and a clamping rod is screwed into the connecting hole.

[0010] Preferably, the end of the clamping rod is provided with a gripping rod.

[0011] Preferably, the connecting sleeve is disposed on the side wall of the fixed clamping plate opposite to the movable clamping plate.

[0012] Preferably, a nut is coaxially welded to the connecting hole, and the clamping rod is screwed to the nut.

[0013] Preferably, the movable clamping plate includes a plate body and a cylinder disposed on the plate body, the cylinder being slidably sleeved on the connecting rod.

[0014] Preferably, a latch is hinged to the cylinder, a spring is connected between the latch and the cylinder, a guide slope is provided at the end of the latch, and the latch can engage with the threaded groove of the screw.

[0015] The beneficial effects of this utility model are as follows: the driving component can drive the movable clamping plate close to the fixed clamping plate, thereby clamping the adjacent wall between the two. Then, railings can be inserted into the connecting sleeves of the two clamps on both sides to protect the adjacent opening. Compared with the prior art, this utility model eliminates the need for fasteners to be driven into the adjacent wall. After construction is completed, the clamps can be disassembled for subsequent construction and reuse, making it convenient and reliable to use. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 3As shown, a reusable edge protection railing clamp includes a connecting rod 1 with two clamping plates. One clamping plate is adapted to move along the axial direction of the connecting rod 1, and can therefore be defined as a movable clamping plate 3; the other clamping plate is fixed to the connecting rod 1, for example, by welding, and can therefore be defined as a fixed clamping plate 2. Furthermore, the connecting rod 1 is also provided with a driving member 4 for driving the movable clamping plate 3 to move axially as desired, that is, the movable clamping plate 3 can move closer to or further away from the fixed clamping plate 2 under the drive of the driving member 4. Additionally, the connecting rod 1 is also provided with a connecting sleeve 5 for inserting a railing 17.

[0022] When installing the edge protection railing, first attach the fixed clamping plate 2 to the edge wall 16, then use the driving component 4 to drive the moving clamping plate 3 closer to the fixed clamping plate 2 until the two clamping plates clamp the edge wall 16. Then, insert the railing 17 into the connecting sleeves 5 of the two clamps on both sides of the edge opening to complete the installation.

[0023] After construction is completed, the clamping plate 3 can be moved in the opposite direction to detach the clamp from the wall 16 for subsequent construction and turnover.

[0024] In some embodiments, the connecting rod 1 may be a screw rod sourced locally at the construction site, and the driving component 4 includes a hand-tightening nut 6 screwed onto the connecting rod 1. The movable clamping plate 3 may specifically include a plate body 11 and a cylinder 12 disposed on the plate body 11, and the axial sliding of the movable clamping plate 3 is achieved by the sliding sleeve of the cylinder 12 and the connecting rod 1.

[0025] By turning the hand-tightening nut 6, the movable clamping plate 3 can be pushed to move closer to or further away from the fixed clamping plate 2, as described above.

[0026] For example, both clamping plates 11 are L-shaped, which makes it easier for the clamping plates to fit against the corners of the adjacent wall 16, increasing the clamping area between the clamping plates and the wall 16 and making the clamping effect more reliable. Correspondingly, the openings of the two clamping plates are set facing each other, thereby achieving clamping at the two corners of the wall 16.

[0027] In a preferred embodiment, the connecting sleeve 5 is positioned on the side wall of the fixed clamping plate 2 away from the movable clamping plate 3, which allows the longer railing 17 to be inserted between the two connecting sleeves 5 without interfering with the wall 16. It is understood that in a possible embodiment, the connecting sleeve 5 may be positioned in the middle of the screw (not shown), in which case the length of the railing 17 is not only limited to the width of the adjacent opening, but also makes insertion of the railing 17 into the two connecting sleeves 5 inconvenient.

[0028] In some embodiments, the connecting sleeve 5 is further provided with a connecting hole 7, and a nut 10 is coaxially welded to the connecting hole 7. A clamping rod 8, which passes through the connecting rod 1, is screwed into the nut 10. When the railing 17 is inserted into the connecting sleeve 5, the clamping rod 8 can be turned to drive the clamping rod 8 to clamp the railing 17 into the connecting sleeve 5, which makes the railing 17 less likely to move freely. Preferably, the end of the clamping rod 8 can be provided with a gripping rod 9 for easy handling by construction personnel.

[0029] In other embodiments, a latch 13 is hinged to the cylindrical body 12 of the movable clamping plate 3, and a spring 14 is connected between the latch 13 and the cylindrical body 12. Under the elastic force of the spring 14, the latch 13 will remain in contact with the screw, especially its end will engage in the threaded groove of the screw. However, the end of the latch 13 is also provided with a guide ramp 15. During the process of the hand-tightening nut 6 pushing the movable clamping plate 3 to clamp the wall 16, the end of the latch 13 will bounce due to the guiding effect of the guide ramp 15, thus making it less likely to interfere with the movement of the movable clamping plate 3 towards the side of the fixed clamping plate 2; after clamping is completed, since the latch 13 is engaged in the threaded groove, the movement of the movable clamping plate 3 away from the side of the fixed clamping plate 2 can be restricted, which makes the clamping state between the clamp and the wall 16 more stable and reliable.

[0030] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
