Abstract

本实用新型涉及钢筋连接技术领域，尤其是一种钢筋直螺纹连接单元，包括两相对设置的钢筋本体，在两所述钢筋本体的相对设置的端部外侧壁上分别加工成型有外螺纹段，两所述外螺纹段之间设置有中间连接框架，各所述外螺纹段的内端均伸至所述中间连接框架的内腔内，在所述中间连接框架的内腔中部一体成型有将内腔分隔成两个分腔的格挡部，在各分腔的内部分别安装有滑移防脱部件，在所述中间连接框架内部和外部的所述外螺纹段的外侧壁上分别旋合有端部螺母。本实用新型通过在钢筋本体端部加工外螺纹段并配合中间连接框架、以及两个配合的端部螺母的夹紧结构，实现相邻两根钢筋本体的快速连接。

Claims

1. A straight-threaded connection unit for reinforcing steel bars, characterized by: The device includes two opposing reinforcing bar bodies. External threaded sections are machined on the outer side walls of the opposing ends of the two reinforcing bar bodies. An intermediate connecting frame is provided between the two external threaded sections. The inner end of each external threaded section extends into the inner cavity of the intermediate connecting frame. A partition is integrally formed in the middle of the inner cavity of the intermediate connecting frame, dividing the inner cavity into two sub-cavities. Sliding and anti-detachment components are installed inside each sub-cavity. The outer end face of each sliding and anti-detachment component is used to abut and position the end of the corresponding external threaded section. End nuts are screwed onto the outer side walls of the external threaded sections inside and outside the intermediate connecting frame. The two end nuts cooperate to clamp the side walls of the intermediate connecting frame.

2. A straight threaded reinforcing bar connection unit according to claim 1, characterised in that: The sliding anti-detachment component includes guide grooves symmetrically and spaced apart on two opposite side walls of the cavity. A sliding plate stand is installed inside the cavity. Insertable sliders are integrally formed on the front and rear sides of the sliding plate stand. Each of the insertable sliders is inserted into the corresponding guide groove. The outer end face of the sliding plate stand abuts against the end face of the external thread section of the steel bar body at its corresponding position. An elastic clamping member is installed in the cavity between the sliding plate stand and the blocking part.

3. A straight threaded reinforcing bar connection unit according to claim 2, characterised in that: The front and rear side walls of the slide plate stand abut against the corresponding inner side walls of the cavity.

4. A straight threaded reinforcing bar connection unit according to claim 3, characterised in that: The elastic clamping member includes a horizontally arranged clamping spring, the inner end of which abuts against the corresponding end of the blocking part, and the outer end of which abuts against the inner end face of the slide plate stand.

5. A straight threaded reinforcing bar connection unit according to claim 4, characterised in that: An inner protrusion is fixedly formed at the center of both end faces of the blocking part. The inner protrusion is coaxially arranged with the pressing spring and extends into the interior of the pressing spring. An outer protrusion is fixedly formed at the center of the inner end face of the sliding plate stand. The outer protrusion is coaxially arranged with the pressing spring and extends into the interior of the pressing spring.

6. A straight threaded reinforcing bar connection unit according to claim 5, characterised in that: The outer end face of the end nut located at the outer end abuts against the shoulder end face between the steel bar body and the external threaded section.

7. A straight threaded reinforcing bar connection unit according to claim 6, characterised in that: All of the aforementioned clamping springs are rectangular cross-section springs.

8. A straight threaded reinforcing bar connection unit according to claim 7, characterised in that: All end nuts are metal lock nuts.
