The first two are mainly used for connecting vertical prefabricated components, the principle is similar, the pre-connecting steel bars are inserted into preset sleeves or round holes, grouting materials are poured or injected (hereinafter, the grouting materials are used for 'pouring' instead of 'pouring') into the sleeves or the round holes, and the connection is completed after the grouting materials are solidified. The grouting compactness and strength in the sleeve or the round hole cannot be detected in a non-destructive manner at present, and bad hidden danger is caused to engineering safety, so that the method is extremely controversial in industry, difficult to be unquestionable, and the connection mode has higher cost, has larger influence on the overall manufacturing cost of the fabricated building, and becomes a main adverse factor of popularization and popularization of the fabricated building; the bolt connection in the mechanical connection is difficult to be popularized generally due to high cost and the like; and other modes in mechanical connection, welding connection, binding connection and the like are mainly used for cast-in-place concrete. Thus, research and development of new connection technologies for concrete elements that are both safe and convenient to save are also a necessary trend.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide the annular pin connecting structure of the concrete member and the construction method thereof, which can effectively improve the safety of the connecting structure, reduce the cost and facilitate the construction.
In order to achieve the above purpose, the annular pin connection structure of the concrete member and the construction method thereof provided by the invention adopt the following technical scheme:
the ring pin connecting structure consists of a ring of a concrete member, a pin bolt and caulking slurry, wherein the ring is exposed outside the concrete member or in a reserved space outside the concrete member, the pin bolt penetrates through the ring and is positioned in the ring, and the caulking slurry is formed by filling bonding slurry in the reserved space of the concrete member and then solidifying.
The ring is a ring rib or a ring sleeve, the ring rib is a U-shaped steel bar ring exposed in a reserved space of the concrete member, the ring sleeve is a closed ring member connected with the steel bar end in the concrete member, and the ring is made of steel and alloy materials.
The ring reinforcement is characterized in that two identical reinforcing steel bars in symmetrical positions in a concrete member are replaced by one identical reinforcing steel bar, the replaced reinforcing steel bar can be processed into a U-shaped ring or a closed ring (mainly rectangular), the replaced reinforcing steel bar is embedded in the concrete member, one end or two ends of the replaced reinforcing steel bar are exposed out of the concrete member, and the exposed ends are reinforcing steel bar rings and are called as ring reinforcement; the exposed end is the non-communication end of the U-shaped reinforcing steel bar, and the two reinforcing steel bar ends are respectively connected with a ring sleeve to form a ring in the second form. The steel bar and the center of the ring sleeve can be on the same line, and also can deviate from the center of the ring sleeve to form an eccentric ring sleeve, and the eccentric ring sleeve can be selected according to engineering conditions. The ring sleeve is mainly made of steel, other alloy materials can be adopted, and the ring sleeve is generally round, oblong, elliptic, rectangular, diamond-shaped and the like. The connection between the ring sleeve and the steel bars can be in the forms of welding, mechanical connection and the like.
Alternatively, a single or a plurality of steel bars in the concrete member are respectively connected with the annular sleeves at two ends of the steel bars, so that the annular pin connection structure is another form.
Optionally, the ring rib and the ring rib, the ring rib and the ring sleeve, and the ring sleeve can be respectively connected by bolts, and can be reasonably selected according to the type of the concrete member and the specific engineering condition.
Optionally, the pin bolt is a steel bar, a steel pipe, a flat steel or a section steel, or can be a combination form of the steel bar, the steel pipe, the flat steel or the section steel; alternatively, other alloy materials may be used for the pin. The pins extend through the rings and are located within the rings to connect the pre-connected rings together. The pre-connected rings are close to each other in parallel, and the bolts are inserted into the two rings to complete the connection of the concrete members in a mechanical connection mode, so that a plurality of pairs of rings can be connected simultaneously by one bolt.
Optionally, the reserved space is a reserved groove and a reserved pin hole in the concrete member, and the reserved pin hole penetrates through the reserved groove and is located in the ring. Concrete slab elements (elements such as plates, e.g. plates and walls) and part of strip elements (elongated elements such as columns and beams) are suitable for this method, if the grooves take the form of unequal widths, inner widths and outer widths, the adhesive slurry in the grooves will form a firm tongue connection after solidification, and double insurance will be achieved when used in conjunction with a pin connection. The term "inner width and outer width" means that the width of a groove varies, and the width is near the inner part of the member and the width is near the edge of the member.
Alternatively, the said void may be a void in the concrete member located at the end of the concrete member, around the member or inside the member, which void may be filled with the bonding slurry and then completed.

The clamping plates are strip-shaped plates clamped on the side surfaces of the concrete members and used for blocking crack pouring slurry in the reserved space, and can be wood plates, steel plates, aluminum plates, alloy plates or plastic plates.
Compared with the similar technology (sleeve grouting connection), the ring pin connection structure has the following advantages:
1. the safety performance is better and more reliable, the pin connection method is equivalent to mechanical connection, and the operation is intuitive and reliable;
2. the construction cost is reduced, and the cost of the sleeve of the current common sleeve grouting connection method can be saved by adopting the annular pin connection structure;
