Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anchoring piece. Background Art

[0002] In concrete structures, in actual work, due to the small width of the main beam 2, when the secondary beam longitudinal reinforcement 3 is anchored into the main beam 2 or the wall, in most cases, it is difficult to increase the length of the straight anchor section of the secondary beam longitudinal reinforcement 3, resulting in a short length of the straight anchor section at the support end of the secondary beam longitudinal reinforcement 3, thereby reducing the anchoring performance.

[0003] For example: HRB400 grade steel bars, concrete strength is C35, the calculated value of the anchorage length lab of the secondary beam longitudinal steel bars 3 is 32d (d is the diameter of the longitudinal steel bars), and the calculated value of the straight anchor section length of the secondary beam longitudinal steel bars 3 at the support end is 0.6lab; when d=18mm, the calculated value of the straight anchor section length of the secondary beam longitudinal steel bars 3 is 0.6x32x18=345.6mm. For the most common 300mm wide main beam in construction projects, the actual straight anchor section of the secondary beam longitudinal steel bars 3 is only 270mm, so it cannot meet the length requirement of the straight anchor section of the secondary beam longitudinal steel bars 3. Utility Model Content

[0007] A connecting sleeve, used for connecting with the longitudinal reinforcement of the secondary beam;

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, there are at least one adjustment anchor plate and at least one pair of supporting reinforcement bars, at least one adjustment anchor plate is arranged on the connecting sleeve, at least one pair of supporting reinforcement bars, each pair of supporting reinforcement bars is symmetrical about the axis of the connecting sleeve, a pair of supporting reinforcement bars corresponds to one adjustment anchor plate, and each supporting reinforcement bar is used to be connected to the longitudinal reinforcement of the main beam.

[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0022] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0023] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise.
