Abstract

The utility model relates to a bolt with an arc-shaped steel plate nut, and belongs to the technical field of construction engineering. The bolt comprises the arc-shaped steel plate nut, a screw rod, a gasket and a nut, wherein the lower end part of the screw rod is connected and fixed with the inner cambered surface of the arc-shaped steel plate nut, the upper end head of the screw rod is a thread structure which cooperates with the nut, the gasket is sleeved on the screw rod through a through hole in the center of the gasket, the nut is screwed on a threaded section at the upper end of the screw rod, the gasket is an arc-shaped steel plate gasket, and a soft gasket is also sleeved between the arc-shaped steel plate nut on the screw rod and the gasket. The bolt with the arc-shaped steel plate nut solves the problem that the small contact area between an ordinary bolt and the wall of raw bamboo intends to cause stress concentration on the wall of the raw bamboo. At the same time, the bolt with the arc-shaped steel plate nut improves the reliability of the connection between raw bamboo rod piece nodes, and can be widely applied in connecting and fixing round rod pieces.

Description

A kind of bolt with the curved plate nut
Technical field
The utility model relates to a kind of bolt with the curved plate nut, belongs to construction engineering technical field.
Background technique
The former bamboo rod member of bamboo The building; The bolted method of normal employing between the former bamboo rod member; But the nut developed area of existing bolt is little and be the plane, when being used for the former bamboo surface of circular arc, is easy to generate the stress concentration phenomenon; Even the use rubber sheet gasket also is difficult to avoid Yuan Zhubi to deform and even destroy.Similarly situation exists in the connection of other circular rod member is fixing equally.
Summary of the invention
The utility model provides a kind of bolt with the curved plate nut, adopts the arc nut, makes bolt in the process that tightens, and other circular rod member wall of former bamboo bamboo wall is in the uniform-compression state all the time, improves the rod member stressing conditions, improves the node connection reliability.
The technological scheme of the utility model is: the bolt of band curved plate nut; Comprise curved plate nut 1, screw rod 3, pad 8 and nut 7; Screw rod 3 underparts connect solid, the worm structure of upper tip for cooperating with nut 7 with curved plate nut 1 intrados; Pad 8 is placed on the screw rod 3 through the through hole at its center, and nut 7 is twisted in screw rod 3 upper end thread sections.Screw rod 3 underparts and curved plate nut 1 intrados connect solid through common modes such as welding.
Said pad 8 is pads of curved plate pad or other form, and there is the through hole that cooperates with screw rod 3 at its center.
Also be with soft pad 6 on the said screw rod 3 between curved plate nut 1 and the pad 8, adopt ordinary soft materials such as rubber, soft plastic to process, the reliability when strengthening the bolt use.
The shape of said soft pad 6 is consistent with pad 8, and there is the through hole that cooperates with screw rod 3 at its center.
During use, the screw rod that the end is welded with the curved plate nut is interspersed on former bamboo or other the circular rod member, and screw rod penetrates former bamboo or other circular rod member, and the place of appearing lays the soft pad of rubber, curved plate pad successively, gets final product with nut is fixing then.
The beneficial effect of the utility model is: can improve plain bolt and former bamboo or other circular rod member wall area of contact is little, stress take place easily concentrate, cause the phenomenon of cleavage fracture, improve the reliability that former bamboo or other circular rod node connect.
Description of drawings
Fig. 1 is the utility model curved plate nut and screw portion structural representation;
Fig. 2 is the practical view of the utility model.
Among the figure: 1-curved plate nut, the 2-weld seam, the 3-screw rod, the former bamboo bamboo of 4-wall, 5-fills out core material, the soft pad of 6-, 7-nut, 8-pad.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, but the protection domain of the utility model is not limited to said content.
Embodiment 1: like Fig. 1, shown in 2; The bolt of this band curved plate nut comprises curved plate nut 1, screw rod 3, curved plate pad 8 and nut 7; Screw rod 3 underparts connect solid, the worm structure of upper tip for cooperating with nut 7 with curved plate nut 1 intrados; Curved plate pad 8 is placed on the screw rod 3 through the through hole at its center, and nut 7 is twisted in screw rod 3 upper end thread sections.Screw rod 3 underparts and curved plate nut 1 intrados connect solid (forming weld seam 2) through welding manner.There is the through hole that cooperates with screw rod 3 at the center of curved plate pad 8; Also be with the soft pad 6 of rubber on the screw rod 3 between curved plate nut 1 and the pad 8, the shape of the soft pad 6 of rubber is consistent with pad 8, and there is the through hole that cooperates with screw rod 3 at its center.
Curved plate is welded on the end of screw rod 3, forms curved plate nut 1; Again the soft pad 6 of rubber is placed on the curved plate nut 1; The former bamboo bamboo wall 4 of then screw rod 3 being filled out core material 5 from injection passes; The place of appearing in screw rod 3 ends lays the soft pad of rubber 6, curved plate pad 8 successively; At last, tighten nut 7, so far, the bolt of band curved plate nut completes.
