Description
Technical field
The utility model relates to the reinforcing steel bar connecting device used on buildings, is a kind of tubular spiral space network reinforcing bar connector.
Background technology
Existing reinforcing bar connector is commonly called as grout sleeve, and it adopts thicker barrel to increase the intensity of grout sleeve.But, when barrel is thicker, what then the diameter of sleeve must do is larger, and larger-diameter grout sleeve in use cannot meet the concrete thickness requirement of stirrup outward between span building outer wall outside the building unit of national regulation, this thickness is referred to as topping, for plate, the topping of wall requires to be at least 15 millimeters, the protective layer thickness of building girder or post at least 20 millimeters, the deficiency of this grout sleeve is: due to the limited space in prefabricated units, when longitudinal reinforcement invariant position, the requirement that protective layer thickness outside grout sleeve and on building unit between stirrup can not be up to state standards, for this reason, longitudinal reinforcement in the concrete of prefabricated units must internally movement between two parties, to reach the thickness requirement of the topping increased between reinforcing bar connector and building unit stirrup, but, this will cause longitudinal reinforcement far from the outer wall of prefabricated component, therefore the ability that result in the resist torque of body of wall also diminishes, thus the stress performance of prefabricated units is reduced, meanwhile, when the topping in prefabricated units reaches thicker requirement, then longitudinal reinforcement can be caused to move to centre, affect the ability of the resist torque of prefabricated units, when prefabricated structure reinforcing bar moves inward, the ability of resist torque diminishes, therefore, the longitudinal reinforcement of prefabricated units is uniform in the both sides of component, can not concentrate mobile to centre, this just requires that the diameter of grout sleeve diminishes, little as far as possible to the middle displacement of precast wall body to meet the longitudinal reinforcement that grout sleeve connects.But, the aperture of grout sleeve is less, grouting amount is lower, bonding strength is caused to reduce, and require that shear wall first horizontal distribution reinforcing bar is 50 millimeters bottom wall according to national standard, but, the height of grout sleeve is generally greater than 100 millimeters, outside the grout sleeve being positioned at body of wall edge member part or shear wall coupling part, must one horizontal hoop be at least set, in this case, when transverse reinforcement is established at grout sleeve position again, then transverse reinforcement distance prefabricated units outer wall is narrower, the requirement of thickness of concrete cover cannot be met, sometimes there is reinforcing steel bars exposed phenomenon, cause reinforcing bar easy-to-rust, and reinforcing bar and concrete cannot be made jointly stressed, have a strong impact on construction quality, in addition, existing grout sleeve in use, in order to the requirement that is up to state standards, need add cracking resistance reinforcing bar in body of wall, prevents the stressed rear generation crack of concrete component, causes construction cost to increase, and difficulty of construction increases, the trapezoidal projection of ring-type on grout sleeve inwall easily produces fracture, causes its intensity significantly to reduce.
