Abstract
The utility model relates to a component for a building template, in particular to a through-wall bolt easy to disassemble, which comprises a through-wall bolt body, wherein one end of a screw rod is matched with a clamp nut. The through-wall bolt is characterized in that two bar-type grooves are symmetrically arranged on the other end of the screw rod circumferentially, and are axially parallel to the screw rod; a check block capable of being folded into each bar-type groove is hinged to one end, deviated from the nut, of each bar-type groove; the length of each check block is two thirds greater than the circumscribed circle diameter of the nut. The through-wall bolt adopting the technical scheme is convenient to use, and can be disassembled from one side by workers.
Description
Technical field
The utility model relates to a kind of construction formwork member, is specifically related to a kind of through-wall bolt.
Background technology
In order to guarantee the safety of high buildings and large mansions, the frame construction of the present building body steel concrete that adopt more, the construction of building frame usually needs to use template, and through-wall bolt is exactly in order to guarantee fixing of template and stablizing of template size.
Conventionally in the time of installation form, can on through-wall bolt, overlap upper bush, so that can reclaim through-wall bolt in form removal, because traditional through-wall bolt two ends are all provided with nut, this makes workman need to, the going back and forth between two places of template, seriously reduce operating efficiency in whens installation and removal.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use, the through-wall bolt that workman can monolaterally dismantle.
In order to solve the problems of the technologies described above, the utility model provides a kind of easy-off through-wall bolt, include screw rod main body through walls, one end of screw rod coordinates with clamp nut, the other end of screw rod is circumferentially symmetrically arranged with two bar-shaped troughs, described bar-shaped trough is parallel with screw axial, and one end that bar-shaped trough deviates from nut is hinged with the block that can fold into bar-shaped trough, and the length of block is greater than 2/3rds of nut circumscribed circle diameter.
Adopt the easy-off through-wall bolt of technique scheme to have the following advantages: because one end of screw rod coordinates with clamp nut, the other end of screw rod is circumferentially symmetrically arranged with two bar-shaped troughs, described bar-shaped trough is parallel with screw axial, one end that bar-shaped trough deviates from nut is hinged with the block that can fold into bar-shaped trough, therefore while use, template directly can be inserted in one end with nut not, block is rocked out to bar-shaped trough, then tightening nuts, when dismounting, reverse operating, in order to guarantee the length of block, the length of block is greater than 2/3rds of nut circumscribed circle diameter, block can better substitute nut and is squeezed in template like this.
As preferred version, in order better to guarantee intensity and the application life of block, the width of described block equals 1/3rd of screw diameter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment easy-off through-wall bolt.
the specific embodiment
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
The utility model provides a kind of easy-off through-wall bolt as shown in Figure 1, include screw rod 1 main body through walls, one end of screw rod 1 coordinates with clamp nut, the other end of screw rod 1 is circumferentially symmetrically arranged with two bar-shaped troughs, described bar-shaped trough and screw rod 1 axially parallel, one end that bar-shaped trough deviates from nut is hinged with the block 2 that can fold into bar-shaped trough, the length of block 2 is greater than 2/3rds of nut circumscribed circle diameter, can be connected in template 3, in order better to guarantee intensity and the application life of block 2, the width of described block 2 equals 1/3rd of screw rod 1 diameter.
Above-described is only preferred embodiment of the present utility model; should be understood that for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
1. an easy-off through-wall bolt, include screw rod main body through walls, one end of screw rod coordinates with clamp nut, it is characterized in that: the other end of screw rod is circumferentially symmetrically arranged with two bar-shaped troughs, described bar-shaped trough is parallel with screw axial, one end that bar-shaped trough deviates from nut is hinged with the block that can fold into bar-shaped trough, and the length of block is greater than 2/3rds of nut circumscribed circle diameter.
2. easy-off through-wall bolt according to claim 1, is characterized in that: the width of described block equals 1/3rd of screw diameter.
