Description
Technical field
The utility model relates to the protruding internal thread hole interconnection system of a kind of pre-buried tyre tension rib assembly, and it is applicable to that frame-shear wall building structure need carry out the pre-buried building wall field of tension rib, belongs to building operations apparatus field.
Background technology
Tension rib is building operations a kind of building materials commonly used, is used for many different environment and position, bears bigger pulling force.Traditional tension rib uses way to have two kinds: a kind of be adopt directly pre-buried; Promptly before concreting, on the template of concrete casting building structure, punch; Then with in the cutting back reinforcing bar patchhole and suitably be fixed, drop preventing, treat after the form removal again with the spreading of electric welding by root.Its shortcoming is when boring is reserved, template to be damaged, and the later stage is faced the time-consuming expense material of sky electric welding.Second kind is the mode that adopts the boring bar planting; Promptly on concrete column, wall, press the punching of brick skin number; Inject the good anchoring agent of allotment behind the clear hole; Insert reinforcing bar then and get final product, there is following shortcoming in this mode: can the concrete wall of finished product be damaged during (1) boring, influence the concrete wall presentation quality; Ratio is difficult for controlling when (2) preparing burden, and causes quality unstable easily, and because the anchoring agent after disposing was promptly solidified in a few minutes, if misoperation very easily causes waste, other also very easily causes the anchoring failure like problems such as moist, clear hole are unclean; (3) the anchoring agent can be aging after using certain time limit, and the tension rib stress performance is reduced, and buries potential safety hazard for the masonry anti-seismic performance.
Summary of the invention
In order to solve existing in prior technology the problems referred to above; The utility model provides the protruding internal thread hole interconnection system of a kind of pre-buried tyre tension rib assembly; It can install tension rib quickly and easily on the concrete casting building structure, have simple in structure, easy construction, a remarkable advantage such as connection is reliable, cost is low.
The utility model technical scheme is to constitute like this; The protruding internal thread hole interconnection system of a kind of pre-buried tyre tension rib assembly is characterized in that: it comprises that the template that can be buckled on the concrete casting building structure is inboard and realizes the dismantled and assembled preburied component that is connected and can realize the dismantled and assembled steel tie member that is connected with preburied component with template is inboard.
Said preburied component comprises a bowl formula fixture, pre-buried interior dentition formula bolt and countersunk head screw; The periphery wall of said pre-buried interior dentition formula bolt is provided with convexity; The bowl end that is provided with the said bowl of internal thread hole formula fixture in pre-buried in the outer end body of dentition formula bolt, be provided with perforation; The aperture of perforation is greater than the screw rod bar footpath of countersunk head screw, less than the outer end end face diameter of dentition formula bolt in pre-buried and the spiral shell head diameter of countersunk head screw; Internal thread hole in the screw rod of said countersunk head screw passes perforation and is located at pre-buried interior dentition formula bolt outer end body is connected; The bowl mouth end of bowl formula fixture is provided with concordant with bowl mouth end and outward extending connected positioning plate, and connected positioning plate is provided with and is used for the screw connecting hole that is connected through the screw realization with template.
In order further to strengthen the connection reliability of pre-buried interior dentition formula bolt and concrete casting building structure; Said convexity is made up of the annular projection around dentition formula bolt periphery wall setting in pre-buried, and the periphery wall of said pre-buried interior dentition formula bolt is provided with the convexity that multiple tracks is positioned at different axial locations.
Said steel tie member is made up of the reinforcing bar rod member, the inner of reinforcing bar rod member be provided with can be located at pre-buried in the external screw thread that is connected of internal thread hole in the dentition formula bolt outer end body.
The operating principle of the utility model technique scheme is explained as follows: during installation; In template (like post, the wall form) manufacturing process of concrete casting building structure; In post, wall form and the concrete surface position that needs are installed tension rib, at the bottom of beam aperture or plate, carry out unwrapping wire, location by the masonry modulus downwards; Dentition formula bolt in pre-buried is fixed on the template inboard through bowl formula fixture with screw (short iron nail); Erection column, wall form afterwards, when built-in fitting is run into reinforcing bar, available hammer rap pre-buried in the dentition formula bolt it is put in a small amount leave, kept away reinforcing bar, closed template is referring to Fig. 1.After having built concrete casting building structure and stripping; Screw according to fixing finds a bowl formula fixture, and a small amount of mortar that infiltrates when removing disturbing concrete unloads countersunk head screw then; The male end of steel tie member is stretched into perforation; Through spanner and pre-buried in the internal thread hole of dentition formula bolt screw and connect, form whole, referring to Fig. 3.
Compared to prior art, the utlity model has following advantage:
(1) the utility model can solve the pre-buried difficult problem of tension rib, avoids on template, holing, and reduces the loss of template; Also without bar planting, directly adopt bolt, nut to connect, not only easy construction, connect reliable, construction cost is low, and work progress do not produce dust, need not the job site weld job, the technology environmental protection.
(2) countersunk head screw that the internal thread hole of dentition formula bolt is fixedly connected usefulness in interim and pre-buried can reuse the reduction use cost.
(3) the utility model is simple in structure, cost of manufacture is low, can entrust factory's batch process or job site to purchase the semiproduct assembling, and processing and fabricating is convenient.
