Problems solved by technology
The lap joint connection method can no longer be used for the connection of large-scale steel bars, and welding has many shortcomings, (such as unstable steel material, poor weldability, etc.; unstable power supply or poor welder level; construction period tightness and insufficient electric capacity; and climate influences such as wind, rain and cold; and construction plans for places with high fire protection requirements; the quality and speed of on-site connection of horizontal steel bars
) Welding quality cannot be guaranteed
The steel bars of existing prefabricated buildings are generally connected by sleeve grouting. The disadvantages of this connection method are as follows: 1. The cost of the sleeve is high; 2. The grouting process is complicated; 3. The construction accuracy is high

Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] Such as Figure 1-Figure 3 As shown, a butt joint sleeve according to the present invention includes a sleeve wall body 1 and a sleeve connector 2, the inside of the sleeve wall body 1 is machined with an internal thread 4, and the outside of the sleeve connector 2 is machined. The external thread 3 is processed, and the sleeve wall body 1 and the sleeve connector 2 are connected and fixed through internal and external threads; the left and right ends of the sleeve connector 2 are fixedly provided with chucks 5, and the sleeve connector 2 is opened There are reinforcing bar holes 7, the two...

The invention relates to the technical field of building assembling, in particular to a butt muff, which comprises a muff wall body and a muff connector, wherein the muff wall body is fixedly connected with the muff connector through internal and external threads; chucks are fixedly arranged on the left and right end parts of the muff connector; a steel bar hole is formed in the muff; flared openings are formed in the two ends of the steel bar hole; a steel bar is arranged in the steel bar hole; a steel bar heading is fixedly connected to the part, in the muff wall body, of the steel bar; the muff connector is formed by splicing two semicircular connector segments. The butt muff has the beneficial effects that the muff wall body and the muff connector are arranged, and the steel bar is embedded into the muff connector to be connected; the threads are arranged inside the muff wall body and outside the connector for matching connection, so that fixation is facilitated; the flared openings and the segmental connector are formed arranged, so that the steel bar heading can be well arranged, fixed and clamped, and can be prevented from sliding out under excessive tensile force, and simplicity and practicability are achieved.
Description
technical field [0001] The invention relates to the technical field of building assembly, in particular to a butt joint sleeve. Background technique [0002] In the construction industry, traditional steel bar connection methods such as lap joints and welding cannot meet the needs of the rapid development of the construction industry in terms of connection quality, efficiency or operability. The continuous updating of steel bar connecting sleeve technology has led to further innovation and continuous technological advancement of the entire industry. Therefore, the steel bar connection technology is quite successful in a certain sense, and has its own characteristics, so that it can adapt to the continuously developing industry and social trends. The lap joint connection method can no longer be used for the connection of large-scale steel bars, and welding has many shortcomings, (such as unstable steel material, poor weldability, etc.; unstable power supply or poor welder le...
