Description
Technical field
It is a kind of cage reinforcing bar connector with cone cylinder the present invention relates to the reinforcing steel bar connecting device used on buildings
And its construction method.
Background technology
Existing reinforcing bar connector is commonly called as grout sleeve, and it increases the intensity of grout sleeve using thicker barrel.But
Be, when barrel is thicker, then the diameter of sleeve must do it is larger, and larger-diameter grout sleeve cannot expire in use
The concrete thickness requirement of stirrup outer wall outside the building element of sufficient national regulation away between building outer wall, this thickness is referred to as and is protected
Sheath, at least 15 millimeters of the protective layer requirement of plate, wall, at least 20 millimeters of the protective layer thickness of building girder or post is this
The deficiency of grout sleeve is：Because the space in prefabricated components is limited, when longitudinal reinforcement position is constant, grout sleeve outside with
The requirement that protective layer thickness on building element between stirrup can not be up to state standards, therefore, in the concrete of prefabricated components
Longitudinal reinforcement must be moved internally between two parties, and the thickness of the protective layer between reinforcing bar connector and building element stirrup is increased to reach
It is required that, but, also therefore this will cause longitudinal reinforcement far from the outer wall of prefabricated component, result in the ability of resist torque of wall
Diminish, so that the stress performance reduction of prefabricated components；Meanwhile, when the protective layer in prefabricated components reaches thicker requirement, then
Longitudinal reinforcement can be caused mobile to centre, the ability of the resist torque of prefabricated components is influenceed；When prefabricated structure reinforcing bar is moved inward,
The ability of resist torque diminishes, therefore, the longitudinal reinforcement of prefabricated components is uniform in the both sides of component, it is impossible to is concentrated to centre and moved
Dynamic, this requires that the diameter of grout sleeve diminishes, and is moved in the middle of precast wall body with meeting the longitudinal reinforcement connected on grout sleeve
Dynamic distance is as small as possible.However, the aperture of grout sleeve is smaller, grouting amount is lower, causes bonding strength to reduce, and according to state
Family's standard requirement first horizontal distribution reinforcing bar of shear wall is 50 millimeters away from wall bottom, but, the height of grout sleeve is typically big
In 100 millimeters, the grout sleeve outside positioned at wall edge member part or shear wall coupling part must be at least provided with together
Horizontal hoop, in this case, when grout sleeve position sets transverse steel again, then transverse steel apart from prefabricated components outer wall compared with
It is narrow, it is impossible to meet the requirement of thickness of concrete cover, occur reinforcing steel bars exposed phenomenon sometimes, cause reinforcing bar easy-to-rust, and cannot
Make reinforcing bar and the common stress of concrete, have a strong impact on construction quality；In addition, existing grout sleeve is in use, in order to reach state
Family standard requirement, need in wall additional cracking resistance reinforcing bar, produce crack after preventing concrete component stress, cause construction cost to increase
Height, difficulty of construction increase；The trapezoidal projection of ring-type on grout sleeve inwall is also easy to produce fracture, causes its intensity to be greatly reduced.
The content of the invention
It is an object of the present invention to provide a kind of cage reinforcing bar connector with cone cylinder and its construction method, it is set thoroughly to change
Become the structure of reinforcing bar connector of the prior art, so as to solve the deficiency of prior art presence.
The present invention to achieve the above object, is achieved through the following technical solutions：A kind of cage reinforcing bar connector with cone cylinder,
