Abstract
The utility model relates to a component for a building formwork, in particular to a quickly-disassembled self-sealing crossing bolt, which comprises a crossing bolt main body and nuts arranged at the two ends of the bolt, wherein the circumcircle diameter of the nut is smaller than the aperture of a bolt hole in the formwork; a U-shaped handle is clamped on the nut; the gap of the handle forms a T-shaped cylinder, the wide gap distance is equal to the opposite side interval of the nut, and the narrow gap is greater than the outer diameter of the bolt and smaller than the opposite side interval of the nut; a rubber layer is arranged on the side, connected with the formwork, of the handle. The crossing bolt provided by adopting the technical scheme of the utility model can be quickly disassembled, and can also seal the gap at the mounting hole.
Description
Technical field
The utility model relates to a kind of construction formwork member, is specifically related to a kind of self sealss through-wall bolt of quickly dismantled.
Background technology
In order to guarantee the safety of high buildings and large mansions, present building body adopts the frame construction of steel concrete more, and the construction of building frame usually needs to use template, and through-wall bolt is exactly a kind of instrument that guarantees its size for fixed form.
Conventionally for form removal time, can reclaim through-wall bolt, in the time of installation form, can on through-wall bolt, overlap upper bush, then set up nut at through-wall bolt two ends, when each installation and removal bolt, all need nut all to screw down, this has increased workman's workload greatly, and while cast in addition, part concrete can flow out along space from the template on nut side, last dry and hard on nut, thus the dismounting difficulty of nut caused.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fast demountable, can also seal the through-wall bolt in gap, installing hole place simultaneously.
In order to solve the problems of the technologies described above, the utility model provides a kind of self sealss through-wall bolt of quickly dismantled, include screw rod main body through walls, and be arranged on the nut at the two ends of screw rod, the circumscribed circle diameter of described nut is less than the aperture of template upper bolt hole, on described nut, be connected with the handle of U-shaped, the gap of handle becomes T shape post, wider clearance distance equals nut opposite side spacing, narrower gap is greater than screw rod external diameter and is less than nut opposite side spacing, and the side that handle and template are joined is provided with rubber layer.
Adopt the self sealss through-wall bolt of quickly dismantled of technique scheme to have the following advantages: because the nut circumscribed circle diameter at the two ends of screw rod is less than the aperture of template upper bolt hole, therefore can quick insertion bolt hole while use, and owing to being also provided with the U-shaped handle of clamping nut, the gap of handle becomes T shape post, wider clearance distance equals nut opposite side spacing, handle can substitute spanner Quick fastening nut like this, because being greater than screw rod external diameter, narrower gap is less than nut opposite side spacing, handle can also substitute the function of pad like this, the side that last handle and template are joined is provided with rubber layer, gap that can well shutoff bolt hole place in the process that handle is tightened like this, prevent that concrete from spilling.
As preferred version, in order better to stop up the gap at bolt hole place, reduce costs simultaneously, the thickness of described rubber layer is 2mm.
Accompanying drawing explanation
Fig. 1 is the structural representation of the self sealss through-wall bolt of the utility model embodiment quickly dismantled.
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 self sealss through-wall bolt of quickly dismantled as shown in Figure 1, include screw rod 1 main body through walls, and be arranged on the nut 2 at the two ends of screw rod 1, the circumscribed circle diameter of described nut 2 is less than the aperture of template upper bolt hole, on described nut 2, be connected with the handle 3 of U-shaped, the gap of handle 3 becomes T shape post, wider clearance distance equals nut 2 opposite side spacing, narrower gap is greater than screw rod 1 external diameter and is less than nut 2 opposite side spacing, handle 3 is provided with rubber layer 4 with the side that template is joined, in order better to stop up the gap at bolt hole place, reduce costs simultaneously, the thickness of described rubber layer 4 is 2mm.
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. the self sealss through-wall bolt of a quickly dismantled, include screw rod main body through walls, and be arranged on the nut at the two ends of screw rod, it is characterized in that: the circumscribed circle diameter of described nut is less than the aperture of template upper bolt hole, on described nut, be connected with the handle of U-shaped, the gap of handle becomes T shape post, and wider clearance distance equals nut opposite side spacing, narrower gap is greater than screw rod external diameter and is less than nut opposite side spacing, and the side that handle and template are joined is provided with rubber layer.
2. the self sealss through-wall bolt of quickly dismantled according to claim 1, is characterized in that: the thickness of described rubber layer is 2mm.
