Embodiment 1

[0020] Plug-in grouting reinforcement connection sleeve, which consists of: sleeve body 1, with a through hole 2 inside the sleeve body 1, elastic rubber sealing rings 3 are installed at both ends of the through hole 2 in the sleeve body, The size of the two ends of the through hole in the sleeve body is different, one end is small and the other end is large, and a group of limit blocks 4 distributed along the inner wall are arranged in the middle of the sleeve body, and the limit block 4 is inserted toward the steel bar There is a slope in the direction, the top of the sleeve body 1 is provided with a grouting hole 5 and an exhaust hole 6 communicating with the inside, the inside ends of the sleeve body have tapered threads, and the sleeve body has a small size The end is connected with the pre-embedded steel bar 8, and the large-size end of the sleeve body is connected and inserted into the steel bar 9.

Embodiment 2

[0022] For the plug-in grouting steel bar connection sleeve described in Example 1, the diameters in the sleeve body are different, the small-sized end is equipped with a small-sized tapered thread, and the large-sized end is equipped with a large-sized tapered thread. Tapered thread, the positions of the limit blocks in the sleeve body are spaced at 120°, and the limit blocks and the sleeve body are integrally cast.

Embodiment 3

[0024] As for the plug-in grouting steel bar connecting sleeve, the circumferential thickness of the elastic rubber sealing ring is larger than the gap between the sleeve and the steel bar, and the inner diameter of the elastic rubber sealing ring is smaller than the outer diameter of the steel bar.

Abstract

The invention discloses an insertion grouted reinforcing steel bar connecting sleeve and a construction method thereof. In the conventional cast-in-place concrete structure, the reinforcing steel bars are connected by mechanical connection methods, such as lap joint connection, welded connection, or sleeve extrusion and the like, the construction of the reinforcing steel bar connection is complex, and the connection of the reinforcing steel bars is finished before concrete is deposited, and fabricated construction cannot be performed. The insertion grouted reinforcing steel bar connecting sleeve comprises a sleeve body (1); a through hole (2) is formed in the sleeve body; elastic rubber seal rings (3) are arranged at two ends of the through hole of the sleeve body; one end of the through hole in the sleeve body is large and the other end of the through hole in the sleeve body is small; a group of limited blocks (4) distributed along an inner wall are arranged in the middle in the sleeve body; slopes are formed on the limited blocks toward the insertion direction of the reinforcing steel bars; a grouting hole (5) and a vent hole (6) which are communicated with the interior are formed above the sleeve body; tapered threads are formed at two ends on the inner side of the sleeve body; the small-sized end of the sleeve body is connected with embedded bars (8); and the large-sized end of the sleeve body is connected with rear insertion reinforcing steel bars (9). The insertion grouted reinforcing steel bar connecting sleeve and the construction method thereof are used for fabricated connection of the reinforcing steel bars.

Description

Technical field: [0001] The invention relates to a method for assembling connection between concrete components by using reinforced concrete components, in particular to a method for assembling and connecting reinforced concrete components realized by a special connecting sleeve for plug-in grouting steel bars. Background technique: [0002] In traditional cast-in-place concrete structures, mechanical connection methods such as lap joints, welded connections, or extruded sleeves are often used for the connection of steel bars. The construction of steel bar connections is relatively complicated, and the connection of steel bars must be completed before pouring concrete. Prefabricated construction. Invention content: [0003] The purpose of the present invention is to provide a method for assembling and connecting reinforced concrete members realized by plug-in grouting reinforcing bar connecting sleeves which is simple in operation, reliable in performance and suitable for ...
