Description
Technical Field
The invention belongs to the field of civil engineering, and particularly relates to a steel bar anchoring plate.
Background
The adhesion between the steel bars and the concrete is affected by the friction of the surface of the steel bars and the anchoring force of the ends of the steel bars. Bending the reinforcing steel bars can reduce the anchoring length of the reinforcing steel bars, but the larger bending inner diameter and the longer bending length can cause local reinforcing steel bar crowding and influence the concrete pouring quality. Set up the anchor board at the reinforcing bar end, not only can obviously reduce reinforcing bar anchor length, can avoid the reinforcing bar intensive moreover, guarantee that concrete placement is closely knit.
The existing anchoring plate has two common modes, one mode is that the anchoring plate is connected with a steel bar through perforation welding; the other is that the steel bars are threaded and then are connected by straight threads. The welding is influenced by the operation level of workers, the end part of the steel bar needs to be processed by the mantle fiber, and the method is not convenient enough. At present, an anchoring plate which can be used without processing the reinforcing steel bars does not exist.
Disclosure of Invention
The invention provides a clamp type steel bar anchoring plate, which aims to solve the defects of the prior art, save the processing of the end part of a steel bar, enable the connection to be used and improve the working efficiency.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a fixture-type steel bar anchoring plate:
the bolt part is provided with an external thread and is provided with a taper hole with the diameter gradually increasing from top to bottom;
the nut part is provided with a second-order shaft hole, wherein the upper hole is an inner screw hole, and the lower hole is a small-diameter hole;
a plurality of clips fixedly arranged above the annular clip hoop;
the clamping piece hoop and the clamping piece are accommodated and fixed in the inner screw hole;
the reinforcing steel bar passes through the taper hole of the bolt part and the second-order shaft hole of the nut part;
the external thread of the bolt part is screwed into the internal thread hole of the nut part, the top ends of the clamping pieces are propped against the inner wall of the taper hole, and the plurality of clamping pieces are inclined inwards to clamp the reinforcing steel bar.
There are 3 clips which are fixed circumferentially and evenly above the annular clip hoop.
The cross section of the clamping pieces from top to bottom is in a circular arc shape with the arc length gradually increasing, and a gap gradually decreasing from top to bottom is formed between the adjacent clamping pieces.
The upper end of a spring is welded below the clamping piece hoop, and the lower end of the spring is welded on the bottom end surface of the inner screw hole of the nut part.
Has the advantages that:
the invention does not need to carry out threading processing on the end part of the steel bar and welding operation, the bolt part and the nut part are in threaded connection, and the steel bar penetrating through the anchoring plate and the anchoring plate can be connected into a whole and directly used by utilizing the matching of the spring, the clamping piece and the tapered hole.

Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor. In order to facilitate an understanding of the invention, the invention is described in more detail below with reference to the accompanying drawings and specific examples.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. As used in this specification, the terms "upper," "lower," "inner," "outer," "bottom," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the invention and simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1 and 2:
the bolt part 1 is provided with a hexagonal bolt head 11 and an external thread 12, and the bolt part 1 is provided with a shaft hole 13, and the shaft hole 13 is composed of a small-diameter hole 14 of 24mm and a taper hole 15 with the diameter gradually increasing from top to bottom which are connected.
As shown in fig. 3 and 4:
the nut portion 2 has a second-step shaft hole 21, in which an upper hole is an internal screw hole 22, an internal thread of the internal screw hole 22 is engageable with the external thread 12 of the bolt portion 1, and a lower hole is a small-diameter hole 23 of 24 mm.
As shown in fig. 5 and 6:
the clip is provided with 3 clips 3, and the cross section of each clip 3 from top to bottom is in a circular arc shape with gradually increased arc length.
3 clamping pieces are welded evenly around the circumference above the annular clamping piece hoop 4, so that a gap 31 which is gradually reduced from top to bottom is formed between the adjacent clamping pieces 3.
The diameter of the outer circular surface of the 3 clamping pieces 3 is smaller than that of the lower end of the taper hole 15.
The upper end of the spring 5 is welded below the clip ferrule 4.
As shown in fig. 7, 8, and 9:
the lower end of the spring 5 is welded on the bottom end surface of the inner screw hole 22 of the nut part 2, so that the combination of the clip 3, the clip hoop 4 and the spring 5 is fixed in the inner screw hole 22.
The national standard ribbed twisted steel 6 with the diameter of 22mm passes through the shaft hole 13 of the bolt part 1 and the shaft hole 21 of the nut part 2.
The external thread 12 of the bolt portion 1 is then screwed into the internal thread hole 22 of the nut portion 2.
Since the diameter of the outer circumferential surface of the 3 clips 3 is smaller than the diameter of the lower end of the tapered hole 15, the 3 clips 3 are inserted into the tapered hole 15.
Along with the descending of the bolt part 1, the top ends of the clamping pieces 3 are pressed by the inner wall of the tapered hole 15 which is gradually reduced, the spring 5 is also compressed, the clamping pieces 3 and the clamping piece hoop 4 descend, and because a gap 31 is formed between the adjacent clamping pieces 3, the clamping pieces 3 have a space which moves obliquely inwards, the upper ends of the clamping pieces 3 are pressed by the inner wall of the tapered hole 15 which is gradually reduced to be inclined inwards, and therefore the 3 clamping pieces 3 clamp the reinforcing steel bars 6.
Therefore, when the device is used, the external thread 12 of the bolt part 1 is connected with the internal thread of the internal thread hole 22 of the nut part 2, and the 3 clamping pieces 3 can be inwards inclined to tightly clamp the steel bar 6 by extruding the 3 clamping pieces 3 through the inner wall of the taper hole 15 of the bolt part 1, so that the effective connection between the anchoring plate and the steel bar 6 is realized.
The spring 5 can give a space for descending the 3 clips 3 and the clip hoop 4, thereby increasing the contact length of the bolt part 1 and the nut part 2 and strengthening the strength of the whole anchoring plate.
