Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, and more specifically, to a protective device for exposed ends at a construction site. Background Art

[0002] Many exposed ends of tied steel bars and scaffolding steel pipes at construction sites pose great safety hazards to construction workers, so they need to be protected. The Chinese patent with announcement number CN218752194U discloses a steel bar end protection device, which is provided with a protective cover, a template and steel bars. A clamping mechanism is installed inside the protective cover, and the clamping mechanism is clamped by an adjustment rod and a clamping plate. When in use, the first adjustment rod is used to bring the two clamps closer to each other, and then the device is tightened on the side of the template, and at the same time, the steel bars on the template are inserted into the protective cover to protect the steel bars and the construction workers. When the structure of the device is relatively complex, when in use, the side of the template needs to be clamped by the clamping mechanism, the operation is not convenient enough, and it relies on the template for clamping support. It is not suitable for steel bar ends or scaffolding steel pipe ends that are far away from the template or have no template. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a construction site exposed end protection device which has a simple structure, is easy to use, and can be directly used in conjunction with the ends of tied steel bars, threaded steel bars, and scaffolding steel pipes.

[0004] In order to achieve these purposes of the utility model, the utility model provides a construction site exposed end protection device, comprising:

[0005] A conical sleeve sleeved with the exposed end, the conical sleeve having a hollow sleeve portion with a diameter that changes from large to small, for adapting to exposed ends of different diameters;

[0006] The buffer body is provided with a sleeve hole which is sleeved and matched with an end of the tapered sleeve with a smaller diameter.

[0007] Preferably, the buffer body is a cone, a sphere, an ellipsoid or a cylinder with spherical ends, and can be sleeved on the outside of the conical sleeve to form buffer protection.

[0008] Preferably, in the construction site exposed end protection device, the sleeve depth of the small diameter end of the conical sleeve is greater than or equal to half the length or diameter of the buffer body, and less than the length or diameter of the buffer body. On the one hand, it ensures that the conical sleeve and the buffer body are sleeved stably, and on the other hand, it prevents the small end of the conical sleeve from passing through the buffer body and affecting the protection effect.

[0009] Preferably, in the construction site exposed end protection device, the sleeve hole is set as a non-through sleeve hole, or is set as a through hole and one end is blocked with a rubber plug. In the event of an accidental impact, the small end of the conical sleeve can be prevented from penetrating one end of the buffer body to cause harm to the human body.

[0010] Preferably, the sleeve hole is a tapered sleeve hole, so that the tapered sleeve and the tapered sleeve hole are more compatible.

[0011] Preferably, in the construction site exposed end protection device, the end of the tapered sleeve with a small diameter is sealed with a plastic cap. The small end of the tapered sleeve is sealed with a cap to prevent puncturing of the buffer body and accidental injury to the human body.

[0012] Preferably, in the construction site exposed end protection device, the tapered sleeve is threadedly matched with the sleeve hole and fixed by bonding, so that the buffer body can be separated from the tapered sleeve in an effective manner.

[0013] Preferably, in the construction site exposed end protection device, the end of the hollow sleeve with a smaller diameter is also filled with a filler, which is hard plastic, sand or sawdust. Hard plastic, sand and sawdust can effectively prevent the exposed end from penetrating the conical sleeve and the buffer body.

[0014] Preferably, in the construction site exposed end protection device, the conical sleeve is a hard plastic conical sleeve, and the buffer body is a sponge foam float.

[0015] Preferably, in the construction site exposed end protection device, reflective tape is pasted on the surface of the conical sleeve and the buffer body.

[0016] The utility model at least has the following beneficial effects:

[0017] The utility model's exposed end protection device for construction sites is composed of a conical sleeve and a buffer body. The conical sleeve can be sleeved with exposed ends of different diameters, such as steel bar ends, bolt ends, threaded steel ends, scaffolding steel pipe ends, etc., so that it is suitable for end scenes with different diameters, which improves applicability; and the buffer body is sleeved on one end of the conical sleeve to play a role of buffer protection, which not only has good protection but also is easy to assemble and disassemble. Compared with the Chinese patent with announcement number CN218752194U that discloses a steel bar end protection device, the utility model's device does not need to rely on a template as the basis for clamping support, so it has a wide range of applications; compared with traditional rubber buffer sleeves, the utility model's device can adapt to exposed ends of different diameters, has higher applicability, and the spherical buffer body has better buffering and protection performance.

[0018] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

[0023] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0024] like Figures 1 to 3 As shown, a construction site exposed end protection device comprises:

[0025] The tapered sleeve 20 sleeved with the exposed end 30 has a hollow sleeve portion 206 with a diameter that gradually decreases, so as to accommodate exposed ends 30 of different diameters.

[0026] The buffer body 10 is provided with a sleeve hole 101 which is sleeved and matched with the end of the tapered sleeve 20 with a smaller diameter.

[0027] In the figure, the conical sleeve has a large end 201 and a small end 202, and the interior is a hollow sleeve portion 206. The buffer body 10 has a sleeve hole 101. The buffer body can be a sponge or rubber body with elastic buffering effect. The structure is very simple. The buffer body can be set to a sphere or cone or ellipsoid or cylinder. In the figure, the buffer body is a cylindrical structure with spherical ends. The sleeve hole is set in the center of the cylinder, which can be directly put on the outside of the conical sleeve to form a buffer protection.

[0028] When in use, the sleeve hole 101 of the buffer body 10 is sleeved and fixed with the small end 202 of the conical sleeve 20, and then the large end 201 of the conical sleeve is inserted into the exposed end 30, such as a bolt end, a threaded steel end, a scaffolding steel pipe end, etc., to perform end protection, which is very convenient to use.

[0029] Compared with the Chinese patent with announcement number CN218752194U, which discloses a steel bar end protection device, it does not require a clamping support foundation, and each exposed end can be sleeved, so it has a wide range of applications in construction sites. Compared with some rubber sleeves, the buffer body of this embodiment is larger and rounder, the buffer surface is larger, the buffer effect is better, and it is more conspicuous. The diameter of the tapered sleeve ranges from large to small, and can be adapted to exposed ends of different diameters. It has higher applicability and is just as simple and easy to use. The diameter of the hollow sleeve portion is set according to the diameter of the exposed end to be sleeved. Taking the scaffolding steel pipe as an example, the maximum diameter is usually about 48mm, and the maximum can reach 60mm. The diameter of the steel bar is 6 to 32mm, so the maximum diameter of the hollow sleeve portion is set to 70mm, and the minimum diameter is set to 5mm.

[0030] Preferably, Figure 2 As shown, the buffer body is a conical or cylindrical structure, and both ends of the cylindrical structure are set to be spherical, with a large buffer area, fewer edges and corners, and good protection effect.

[0031] Further, in another embodiment, Figure 2 and 3 As shown, the sleeve depth of the end with a smaller diameter of the conical sleeve 20 is greater than or equal to half the length or diameter of the buffer body 10, and is less than the length or diameter of the buffer body. In the legend, the depth of the sleeve hole is greater than half the length of the buffer body 10, and is less than the length of the buffer body 10, so that the conical sleeve 20 can be fully inserted into the sleeve hole. This embodiment sets the sleeve depth to ensure that the conical sleeve and the buffer body are sleeved stably to prevent accidental detachment. At the same time, the conical sleeve does not extend beyond the other end of the sleeve hole of the buffer body, which can prevent the small end of the conical sleeve from passing through the buffer body to form a convex portion and affect the protection effect.

[0032] Further, in another embodiment, Figure 2 As shown, the sleeve hole 101 is preferably set as a non-through sleeve hole. When it is set as a through hole, a rubber plug is needed to plug one end of the sleeve hole. The through hole structure can be inserted into the conical sleeve from one end at will, which is convenient for installation. The rubber plug can be a rubber plug. Figure 2 The structure of the non-through hole is described. The depth of the non-through hole only needs to be greater than half the length of the buffer body and less than the length of the buffer body. When an accidental impact occurs, the small end of the conical sleeve can be prevented from penetrating the buffer body and causing harm to the human body.

[0033] Further, in another embodiment, the sleeve hole 101 is a tapered sleeve hole. Figure 2 As shown, the conical sleeve hole is arranged at the center of the buffer body, and is a non-penetrating conical sleeve hole, which is tightly combined and fixed with the conical sleeve, and effectively prevents the conical sleeve from further penetrating the sleeve hole.

[0034] Preferably, a blocking block 102 is further provided in the conical sleeve hole. In the figure, the blocking block is a hard plastic conical block, which is inserted into the deepest part of the conical sleeve hole to prevent the conical sleeve from penetrating the sleeve hole.

[0035] Further, in another embodiment, Figure 3 As shown, the end of the tapered sleeve 20 with a small diameter is sealed with a plastic cap 205. Preferably, the plastic cap 205 is inserted into the small end of the tapered sleeve and fits tightly with the small end of the tapered sleeve. The plastic cap 205 of this embodiment increases the contact area and resistance, preventing the small end 202 of the tapered sleeve from piercing the buffer body and preventing accidental injury to the human body.

[0036] Further, in another embodiment, Figure 3 As shown, the tapered sleeve 20 is threadedly matched or adhesively fixed to the sleeve hole 101 of the buffer body. In the figure, the outer wall of the small end 202 of the tapered sleeve is provided with a threaded section 203, and the length of the threaded section can be set as needed, and the entire outer wall of the tapered sleeve is also provided with a threaded section. After the tapered sleeve is screwed into the sleeve hole 101, the friction force can be increased, and the bonding strength between the small end 202 of the tapered sleeve and the buffer body 10 can be improved to prevent separation during impact.

[0037] Further, in another embodiment, Figure 3 As shown, the end of the hollow sleeve 206 with a smaller diameter is also filled with a filler 204, which can be a hard plastic block, sand or wood chips. In the figure, a conical hard plastic block is used as the filler. Before inserting the leaking end, first insert the hard plastic block, sand or wood chips into the hollow sleeve 206 from the large end, and then insert the exposed end. The hard plastic block, sand or wood chips can provide resistance or buffer to the exposed end, thereby effectively preventing the leaking end from penetrating the conical sleeve and the buffer body.

[0038] Further, in another embodiment, Figure 1 As shown, the conical sleeve 20 is a hard plastic conical sleeve, and the buffer body 10 is a sponge foam float. For example, the plastic conical wall sleeve is a commonly used material in construction, and the sponge foam float is often used as a float. The combination of the two is simple and easy to use, low cost, and practical.

[0039] Further, in another embodiment, Figure 1 As shown, reflective tape 40 is attached to the surface of the conical sleeve 20 and the buffer body 10, so as to remind construction workers to pay attention and reduce collision accidents.

[0040] The device of the utility model has a simple structure. When in use, the plastic pipe cap 205 is inserted into the small end 202 of the tapered sleeve, and the buffer body is sleeved on the small end of the tapered sleeve to fix the buffer body to the tapered sleeve. After the tapered hard plastic block or sand or wood chips are inserted into the interior of the tapered sleeve as a filler 204, the tapered sleeve is sleeved on the exposed end. The use is very convenient. One product can adapt to exposed ends of different diameters such as bolts, threaded steel bars, steel pipes, etc. It has a wide range of applications and is very practical.

[0041] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
