Description

Reinforcing steel bar bending sleeve

Technical Field

The application relates to the technical field of constructional engineering, in particular to a steel bar bending sleeve.

Background

The building engineering is an engineering entity which performs various technical works and completions such as planning, surveying, designing, constructing, completing and the like for newly building, reconstructing or extending building buildings and affiliated structures and installation engineering of lines, pipelines and equipment matched with the engineering entity. Also refers to the construction of various houses and buildings, also known as the construction workload. The investment amount of the part can be realized only by the construction activities with the need of carrying out the work and the material movement.

The construction project of the house building comprises factory buildings, theaters, hotels, shops, schools, hospitals, houses and the like, and the new construction, reconstruction or extension of the house building can be realized only by construction activities with materials required; the 'auxiliary structure facilities' refer to water towers, bicycle sheds, pools and the like which are matched with the house building. The 'installation of lines, pipelines and equipment' refers to the installation activities of the lines, pipelines and equipment such as electricity, water supply and drainage, heating and ventilation, communication, intellectualization and elevators which are matched with the house building and the auxiliary facilities thereof.

The steel bar is steel for reinforced concrete and prestressed reinforced concrete, and the cross section of the steel bar is circular or square with round corners. Comprises plain round steel bars, ribbed steel bars and twisted steel bars. The reinforcing steel bar for reinforced concrete is straight bar or wire rod steel for reinforcing steel bar for reinforced concrete, and has two shapes, i.e. plain steel bar and deformed steel bar, and two kinds, i.e. straight bar and wire rod, in delivery state. The plain round steel bars are actually small round steel and wire coils of ordinary low-carbon steel. Deformed bars are surface ribbed bars, usually with 2 longitudinal ribs and transverse ribs distributed uniformly along the length. The cross ribs are 3 types of spiral, herringbone and crescent shapes. Expressed in millimeters of nominal diameter. The nominal diameter of the deformed steel bar is equivalent to the nominal diameter of the smooth steel bar with the same cross section. The nominal diameter of the steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40 mm. Steel grade: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Steel reinforcement is primarily subjected to tensile stresses in concrete. The deformed reinforcing steel bar has great binding capacity with concrete and thus can bear outer force well. Reinforcing bars are widely used in various building structures. Especially large, heavy, light-duty thin-walled and high-rise building structures.

To the above-mentioned correlation technique, the inventor thinks that need use the sleeve of bending in the reinforcing bar bending process, will bend the sleeve cover and establish behind the reinforcing bar bundle, through pulling the reinforcing bar of tip, make the reinforcing bar bend at the sleeve portion of bending, however traditional sleeve of bending is established and is restrainted the effect poorly after the reinforcing bar bundle surface, still can remove, causes the situation that the sleeve of bending appears the skew easily, and then leads to the reinforcing bar to bend and appear the deviation, leads to the sleeve to drop easily when bending simultaneously, greatly reduced the convenience when bending the reinforcing bar.
