Abstract
The utility model relates to a fixing device of anchor bolt, comprising a locating device and at least two anchor bolts. The anchor bolt fixing device is characterized in that the locating device comprises at least one group of symmetrical steel plates which comprises more than two and are arranged from top to bottom; the side surfaces of the steel plates are connected by a reinforcing steel bar; holes are arranged at the corresponding positions of the steel plates; the diameter of the holes is 1-5mm larger than that of the anchor bolts; and the anchor bolts pass through the holes and are fixedly connected with the steel plates. When the anchor bolts are installed, the precision can meet the standard requirements easily, and the firmness and the stability are better after the installation.
Description
Technical field
The utility model relates to the building machinery field, particularly the fastening devices of stone bolt.
Background technology
One end of stone bolt need be embedded in the concrete body, is unlikely to be pulled out in order to be connected with the concrete body securely, and the lower end of common stone bolt is rived into herringbone or is annular or for L shaped.Because the special construction of stone bolt self and pre-buried mounting method, to be 5mm at the axis shift allowable variation always be a difficult problem with interior to the Positioning Precision Control that makes stone bolt.And GB 50205-2001 " code for acceptance of construction quality of steel structures " regulation steel work fundamentally foot bolt axis shift allowable variation be 5mm, belong to the master control project.In practice of construction, also there is employing control template to be set on stone bolt top, the stone bolt that control template positions is equipped with in this upper end, though when installing and locating, make moderate progress on the precision, but it is after this stone bolt installs, firm inadequately, easily loosening, and for the bigger large foundation bolt of buried depth, requirement of strength to control template is also higher, and when single column foundation when not being very big, is easy to cause off normal during the vibration concrete.
The utility model content
Precision can reach standard-required with comparalive ease when the technical problems to be solved in the utility model provided a kind of installation, and installed back firmness and the stability fastening devices of stone bolt preferably.
For solving this technical problem, the technical solution adopted in the utility model is as follows:
The stone bolt fastening devices, comprise positioner and at least two stone bolt, it is characterized in that described positioner comprises the steel plate of the symmetry of at least one group of two upper and lower settings, the side of two block plates connects with reinforcing bar, corresponding position is provided with the hole on two block plates, the diameter in hole is than the big 1 ~ 5mm of diameter of stone bolt, and stone bolt passes from the hole and be affixed with steel plate.
Described fastening devices also comprises a cross yoke and is arranged at the template of two symmetries on the cross yoke positive and negative, the hole that two corresponding positions of template are provided with on the described steel plate that Kong Bingyu is positioned at its below is corresponding, the diameter in hole is than the big 1 ~ 5mm of diameter of stone bolt on the template, and stone bolt passes from the hole of two wooden forms.
Be provided with fixedly reinforcing bar of right-angled intersection between the described stone bolt.
The top of described stone bolt be provided with screw thread and with the nut of threads engaged.
Adopt the fastening devices of the stone bolt of technique scheme, because the template with steel plate and band cross positions bolt simultaneously on bolt, and on the steel plate and the aperture of the locating hole of establishing on the template is than the big 1 ~ 5mm of diameter of bolt, can guarantee that like this bolt shaft linear displacement allowable variation is in the 5mm, reaches the national regulation requirement.Because be welded with steel plate on the bolt, the upper end is fixed form again, welds fixedly reinforcing bar of right-angled intersection between the stone bolt again, adopt this to be cast in the concrete body with the fixing stone bolt of structure after, stone bolt can not become flexible, its firmness and stable very good.
