Description
Technical field
The utility model relates to a kind of pre-embedded bolt interconnection system 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 time-consuming material that takes of later stage 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 a kind of pre-embedded bolt interconnection system 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; A kind of pre-embedded bolt interconnection system 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-embedded bolt and the temporary fixed nut of using, the screw rod outer end of said pre-embedded bolt from be located at perforation at the bottom of bowl formula fixture bowl and stretch in bowl formula fixture and be located at bowl formula fixture in temporary fixedly be connected with nut thread; The bowl mouth end of said 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 to make pre-embedded bolt that certain swing space arranged and to fix the operating space that is connected with nut with nut and drawknot with temporary fixed; The aperture of said perforation is greater than the screw rod bar footpath of pre-embedded bolt.
Said steel tie member comprises and can fix the external tension rib that is fixedly connected with nut with nut and with drawknot with the drawknot that the screw rod outer end realization of pre-embedded bolt is threaded is fixing.
Said external tension rib comprises the long reinforcing bar of a bending and the bar dowel of a bending; The inner of long reinforcing bar and bar dowel is fixedly welded on the fixing sidewall of both sides up and down with nut of drawknot respectively; The middle part of long reinforcing bar and the welding of the outer end of bar dowel are fixing, and the direction extension with the link position of nut is fixed to screw rod that deviates from pre-embedded bolt and drawknot in the outer end of long reinforcing bar.The length of bar dowel satisfies fusion length, and the length of long reinforcing bar satisfies the tension rib laying length and gets final product.
Connect for ease, said temporary fixed fixing with nut and drawknot is the lengthening hex nut with nut.
Bar dowel and drawknot are fixed the fixing weld seam that forms with welding between the weld seam that welds formation between the nut and long reinforcing bar and the bar dowel of the weld seam, long reinforcing bar and the drawknot that form with welding between the nut and are two-sided full weld weld seam, and the length >=12mm of each weld seam.
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; Pre-embedded bolt is fixed on the template inboard through bowl formula fixture with screw (short iron nail); Erection column, wall form afterwards, when built-in fitting was run into reinforcing bar, available hammer rapped pre-embedded bolt and it is put in a small amount leave, kept away reinforcing bar, and 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; The a small amount of mortar that infiltrates when removing disturbing concrete unloads with nut temporary fixed then, and fixing the screwing through the screw rod of thread and pre-embedded bolt with nut of the drawknot that is welded with external tension rib connected; Form integral body, referring to Fig. 5.
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) be fixedly connected the temporary fixed of usefulness with the screw rod of pre-embedded bolt and can reuse, reduce use cost temporarily with nut.
(3) the utility model simple in structure,, cost of manufacture is low, can entrust factory to produce in batches or the semiproduct assembling is purchased in the job site, processing and fabricating is convenient.
