Abstract
Description
Technical Field
[0001] This invention relates to a protective device, and more particularly to a steel bar sleeve that can be fitted onto the top of a steel bar to protect the safety of construction workers. Prior Technology
[0002] Currently, various specifications of steel bars, steel, iron parts, aluminum parts, or other materials used in the workplace have sharp points. Without any protective measures, workers are prone to occupational accidents. Conventional protective measures include covering the sharp points with painted panels, strips, wooden boards, or other materials as a barrier. However, such protective measures are prone to falling off, shifting, or becoming ineffective due to collisions or unevenness at the sharp points.
[0003] A more common and preferable method is to install a cut-off plastic hose or a special protective sleeve at the tip. This special sleeve mainly has a axial hole through which the tip can be inserted, allowing protection to be fitted onto the material's tip. However, in practical workplace applications, due to the varying sizes, lengths, and heights of different materials, users either use a single-size sleeve on a single-size material tip as usual, or they must use different sized sleeves for different sized materials. Often, to save costs, only a single-size sleeve is used, even when the material tip is not... The use of the same size material at the sharp point can lead to inadequate protection; or the sheath may deform, fall off, or become unsuitable after repeated use. The main reason for this is that different sizes of sheaths are required for different specifications, and since sheaths are consumables, businesses are forced to use them due to legal regulations. If different sheaths are used for different sizes of materials, the cost will be relatively high. Therefore, the convenience, safety, and stability of traditional sheaths or protective measures are obviously insufficient, and construction workers are prone to accidents that can result in injuries or even loss of life. This situation is most serious in cases of disasters at construction sites.
[0004] Before the completion of the building's foundation structure, exposed rebar ends are frequently seen during each stage of construction. Given the often chaotic construction site environment and the lack of protective devices for these exposed rebar ends, construction workers are prone to falls or collisions due to human or environmental factors. If an accident occurs at a location with exposed rebar, or if workers collide with protruding rebar while moving on scaffolding or carrying materials, serious injuries from rebar piercing the body are possible. Therefore, it is essential to provide protective measures for exposed rebar ends to ensure the safety of construction workers in creating the work environment.
[0005] In view of the lack of convenience, safety and stability of traditional protective sleeves or protective measures, and the problem that they are prone to deformation after repeated use, the inventors developed a "steel reinforcement sleeve" that is sturdy, durable, simple and convenient, safe and stable, to solve the above problems.
[0006] In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty that the inventor of this case wants to solve; therefore, based on years of experience in related industries, the inventor of this case has devoted himself to research and improvement for many years, and finally successfully developed this case, thus giving birth to this invention to improve its effectiveness.

The steel bar retaining sleeve of this invention includes: a tube body 10, the tube body 10 having a first receiving hole 11 inside; to further improve the fastening ability, the tube body 10 is further provided with a second receiving hole 12 communicating with the first receiving hole 11. The diameter of the second receiving hole 12 is smaller than that of the first receiving hole 11, so that a transition tapering section 13 is formed between the first receiving hole 11 and the second receiving hole 12. The inner diameter of the end of the transition tapering section 13 connected to the first receiving hole 11 is larger than that of the end of the transition tapering section 13 connected to the second receiving hole 12, so that the cross-section of the transition tapering section 13 is inclined; in addition, the first receiving hole 11 and the second receiving hole 12 can also be continuous tapering holes or conical holes.
[0025] A first clamping unit 20 is disposed on one side of the tube body 10.
[0026] A second clamping unit 30 is disposed on the other side of the tube body 10, and the first clamping unit 20, the tube body 10 and the second clamping unit 30 are arranged side by side in sequence, so that the tube body 10 is located between the first clamping unit 20 and the second clamping unit 30.
[0027] The top surfaces of the first clamping unit 20 and the second clamping unit 30 are flush with the top surface of the tube body 10; the height of the first clamping unit 20 and the second clamping unit 30 is less than the height of the tube body 10.
[0028] Please refer to Figures 1 and 3. The first clamping unit 20 and the second clamping unit 30 each include a plurality of first clamping pieces and a plurality of second clamping pieces 31. Each of the first clamping pieces 21 is arranged opposite to each other and spaced apart. The inner side of each of the first clamping pieces 21 is arc-shaped and forms a first clamping groove 22. Each of the second clamping pieces 31 is arranged opposite to each other and spaced apart. The inner side of each of the second clamping pieces 31 is arc-shaped and forms a second clamping groove 32. In this embodiment, the size of the first clamping groove 22 is larger than that of the second clamping groove 32, but it is not limited thereto.
[0029] The first clamping unit 20 and the second clamping unit 30 each have a first open end and a second open end, and the first open end and the second open end are respectively connected to the first clamping groove 22 and the second clamping groove 32.
[0030] Each of the first clips 21 and each of the second clips 31 has a plurality of first guide pieces 23 and a plurality of second guide pieces 33 at one end. Each of the first guide pieces 23 and each of the second guide pieces 33 is obliquely arranged outward, so that a plurality of first contraction portions 24 are formed between each of the first guide pieces 23 and each of the first clips 21; and a plurality of second contraction portions 34 are formed between each of the second guide pieces 33 and each of the second clips 31.

When the first rebar A is thicker and inserted into the first receiving hole 11, the top surface of the first rebar A abuts against the transition tapering section 13 and is secured; when the first rebar A is thinner, the first rebar A passes through the first receiving hole 11 and is inserted and secured in the second receiving hole 12.
[0032] The first clamping unit 20 and the second clamping unit 30 respectively provide a predetermined position for vertically clamping a second reinforcing bar B and a third reinforcing bar C; the reinforcing bar retainer, the first reinforcing bar A, the second reinforcing bar B and the third reinforcing bar C are covered by a concrete (not shown) to form a wall or a column.
[0033] Furthermore, the top end of the first reinforcing bar A is fastened in the first receiving hole 11 and the second receiving hole 12, and the transition tapering section 13 between the first receiving hole 11 and the second receiving hole 12 makes it easier to insert the first reinforcing bar A; the second reinforcing bar B and the third reinforcing bar C are smoothly inserted into the first receiving hole 11 and the second receiving hole 12 by the first guide piece 23 and the second guide piece 33, and the first receiving hole 11 and the second receiving hole 12 use the clamping force generated by the expansion of the material to provide elastic clamping for the second reinforcing bar B and the third reinforcing bar C.
[0034] The first receiving hole 11 and the second receiving hole 12 are provided for installing the first reinforcing bar A with the number of reinforcing bar #3 and #4, which improves the flexibility of the pipe body 10; the first clamping unit 20 and the second clamping unit 30 are provided for installing the second reinforcing bar B and the third reinforcing bar C with the number of reinforcing bar #5 to #11.
