Description
本发明属于建筑锚栓的技术领域,特别涉及一种抗震型锚栓。 The invention belongs to the technical field of building anchors, in particular to an earthquake-resistant anchor bolt.
传统的建筑锚栓如图1所示,由螺母100、螺杆200及膨胀件300组成,螺杆200的里端具有楔形头201,膨胀件300呈管状且里端具有齿片301,膨胀件300套在螺杆200上,其齿片301抵在楔形头201上,螺母100螺套在螺杆200的外端。As shown in FIG. 1 , the conventional anchor bolt is composed of a nut 100, a screw 200 and an expansion member 300. The inner end of the screw 200 has a wedge-shaped head 201. The expansion member 300 has a tubular shape and has a tooth piece 301 at the inner end and 300 sets of the expansion member. On the screw 200, the tooth piece 301 abuts against the wedge head 201, and the nut 100 is screwed over the outer end of the screw 200.
安装时,将套有膨胀件300的螺杆200插入钻好的墙孔中,再将外挂物挂置在螺杆200的外端,然后,将螺母100螺套在螺杆200上,通过旋拧螺母100向墙孔内推挤膨胀件300,使膨胀件300的里端齿片301在楔形头201的导引下胀开,紧紧抓住墙孔的内壁,而令整个锚栓固定在墙孔中,达到将外挂物固定在建筑上的目的。During installation, the screw 200 sleeved with the expansion member 300 is inserted into the drilled wall hole, and the external object is hung on the outer end of the screw 200. Then, the nut 100 is screwed onto the screw 200, and the nut 100 is screwed. Pushing the expansion member 300 into the wall hole, so that the inner end tooth piece 301 of the expansion member 300 is expanded under the guidance of the wedge head 201, and firmly grasps the inner wall of the wall hole, so that the entire anchor bolt is fixed in the wall hole. To achieve the purpose of fixing the external objects on the building.
经分析,上述锚栓存在诸多缺陷:因为膨胀件300的齿片301个数少,与墙孔的接触面小,抓紧力不足;而且,膨胀件300的齿片301是由螺杆200里端的楔形头201导引而胀开,胀开慢,胀开后的角度小,也导致抓紧力不足。所以,现有建筑锚栓的抓紧力不足,锚固功效差,抗震性差。After analysis, the anchor bolt has many defects: because the number of the teeth 301 of the expansion member 300 is small, the contact surface with the wall hole is small, and the gripping force is insufficient; moreover, the tooth piece 301 of the expansion member 300 is wedge-shaped at the inner end of the screw 200. The head 201 is guided to expand, and the expansion is slow, and the angle after the expansion is small, which also leads to insufficient grasping force. Therefore, the existing building anchor bolt has insufficient gripping force, poor anchoring effect, and poor earthquake resistance.
有鉴于此,本发明人对建筑锚栓的结构加以改进,遂有本案产生。In view of this, the inventors have improved the structure of the building anchor, and the present invention has been produced.
本发明的目的在于提供一种抗震型锚栓,其抓紧力强,具有良好的锚固功效,抗震性强,且结构简单,加工制作方便。The object of the present invention is to provide an anti-vibration type anchor bolt, which has strong gripping force, good anchoring effect, strong earthquake resistance, simple structure and convenient processing and manufacture.
为了达成上述目的,本发明的解决方案是:In order to achieve the above object, the solution of the present invention is:
一种抗震型锚栓,由螺母、螺杆及至少二个膨胀件组成;螺杆的外端具有螺纹段而里端具有螺栓头;数个膨胀件逐一套置在螺杆的螺纹段上;螺母旋拧在螺杆的螺纹段上;其中,膨胀件是由一片材冲压后卷曲而成的管件,相邻两个膨胀件的相对端形成相互交叉的长齿片和短齿片,且长齿片的端部向外折弯。An anti-vibration type anchor bolt consists of a nut, a screw and at least two expansion members; the outer end of the screw has a threaded section and the inner end has a bolt head; a plurality of expansion parts are placed one by one on the threaded section of the screw; the nut is screwed On the threaded section of the screw; wherein the expansion member is a tubular member which is formed by rolling a sheet of material, and the opposite ends of the adjacent two expansion members form long and short teeth which intersect each other, and the long teeth The ends are bent outwards.
所述靠螺栓头的膨胀件里端延伸形成定位条,定位条弯折形成定位钩,此定位钩勾在螺杆的螺栓头上。The inner end of the expansion member of the bolt head extends to form a positioning bar, and the positioning bar is bent to form a positioning hook, and the positioning hook is hooked on the bolt head of the screw.
所述螺杆的螺栓头侧壁上对应膨胀件的定位条和定位钩开有定位槽,定位条和定位钩处于定位槽中。A positioning groove corresponding to the expansion member and a positioning hook are formed on the side wall of the bolt head of the screw, and the positioning bar and the positioning hook are located in the positioning groove.
所述螺杆的螺纹段上先套置一个垫圈再旋拧螺母。A threaded washer is placed on the threaded section of the screw and the nut is screwed.
所述螺栓头一体成型在螺杆上。The bolt head is integrally formed on the screw.
所述螺栓头与螺杆分体成型,螺栓头固定在螺杆上。The bolt head and the screw are separately formed, and the bolt head is fixed on the screw.
采用上述结构后,本发明安装时,在墙体上钻孔,将膨胀件套在螺杆上,再将螺杆的螺栓头朝里插在预先钻好的墙孔中,然后,将外挂物挂置在螺杆上,最后,将螺母旋在螺杆的螺纹段上,使数膨胀件受挤,沿螺杆轴线方向的间距压缩,导致长齿片在短齿片面上滑动,滑动过程中产生两种位移,一是沿螺杆轴线方向的位移,使得相邻膨胀件之间的间距压缩,二是沿螺杆径线方向的位移,使得长齿片的曲面外径不断加大,长齿片不断地切入墙体中,因为相邻的膨胀件的长齿片和短齿片交叉对插,所以就形成了相对切底的效果,使得锚栓沿螺杆的轴线双向受力,抗震性能大大提高。After the above structure is used, when the invention is installed, the wall is drilled, the expansion member is placed on the screw, and the bolt head of the screw is inserted into the pre-drilled wall hole, and then the external object is hung on the wall. On the screw, finally, the nut is screwed on the threaded section of the screw, so that the plurality of expansion members are squeezed and compressed along the pitch of the screw axis, causing the long toothed piece to slide on the short toothed surface, and two displacements are generated during the sliding process. It is the displacement along the axis of the screw, so that the spacing between adjacent expansion members is compressed, and the second is the displacement along the direction of the screw diameter, so that the outer diameter of the curved surface of the long tooth piece is continuously increased, and the long tooth piece is continuously cut into the wall. Because the long and short teeth of the adjacent expansion members are interdigitated, the effect of the opposite cutting is formed, so that the anchor is subjected to the bidirectional force along the axis of the screw, and the seismic performance is greatly improved.
本发明因为有至少两个膨胀件,每个膨胀件都有长齿片,使膨胀件与墙孔的接触面倍增,抓紧力大大提高,所以,固定效果好。而且,本发明结构简单,加工生产时膨胀件由一片材冲压后卷曲而成,十分方便。The invention has at least two expansion members, each of which has a long tooth piece, so that the contact surface of the expansion member and the wall hole is doubled, and the gripping force is greatly improved, so the fixing effect is good. Moreover, the structure of the invention is simple, and the expansion member is formed by curling a sheet of material after processing, which is very convenient.

The opposite ends of the adjacent two expansion members 3 form long teeth 31 and short teeth 32 which intersect each other, and the ends of the long teeth 31 are bent outward. In order to allow the expansion member 3 to be rapidly expanded after being squeezed, and to prevent the expansion member 3 from rotating relative to the screw 2, the inner end of the expansion member 3 shown in Figs. 5 and 6 is further extended to form a positioning strip 33, and the positioning strip 33 is bent to form a positioning. A hook 34 is hooked on the bolt head 22 of the screw 2. In this embodiment, the positioning bar 33 and the positioning hook 34 of the expansion member 3 on the side wall of the bolt head 22 of the screw 2 are further provided with a positioning groove 23, and the positioning bar 33 and the positioning hook 34 are located in the positioning groove 23, so that the expansion member 3 The inner end is fixed with the bolt head 22 of the screw 2, and the expansion effect is better.
螺母1旋拧在螺杆2的螺纹段21上,且抵在图7和图8所示膨胀件3的外端上。为了组装更可靠,此实施例在螺纹段21上先套置垫圈4再旋拧螺母1。The nut 1 is screwed onto the threaded section 21 of the screw 2 and abuts against the outer end of the expansion member 3 shown in Figs. In order to make the assembly more reliable, this embodiment first sleeves the washer 4 on the threaded section 21 and then screws the nut 1.
