Description
Technical Field
The invention relates to the technical field of assembly type buildings, in particular to a prefabricated wall high-strength concrete connection node and a construction method.
Background
The fabricated building is a building with the main parts of a structure system, an outer protection system, equipment, a pipeline system and an inner installation system integrated by prefabricated parts. In the fabricated concrete building, part or all of the components of the structural system are produced in a component prefabrication factory and then transported to a construction site in a corresponding transportation mode, and the components are assembled by adopting a reliable connection technology by adopting a reliable installation mode and an installation machine, so that the building with the use function is formed.
The integral performance of the structure is similar to that of a cast-in-place structure when the stressed steel bars are connected in a safe and reliable mode and the joint parts of the prefabricated components and cast-in-place and post-cast concrete are joint positions, namely joints, rough surfaces, key grooves and other construction measures are adopted between new concrete and old concrete at the joints. Under the condition, the assembled integral structure can be used for analyzing various structural design conditions by adopting the same method as a cast-in-place concrete structure, namely, the design concept of the same cast-in-place structure is adopted, and meanwhile, the key components are treated by reinforcement measures. Therefore, the connection of the joint of the prefabricated part and the cast-in-place concrete of the prefabricated part is of great importance to the structural safety and becomes a key technology for judging whether the integral performance of the fabricated building can meet the integral performance. The node design of the connecting part of the prefabricated parts needs to fully consider the production and construction convenience of the prefabricated parts, and meanwhile, a proper connecting technology needs to be adopted to ensure the effective stress transfer of the connecting part.
The pressure at the joint is directly transmitted through post-cast concrete, grouting material or sitting slurry; the tension is transmitted through the steel bars and the embedded parts which are connected in various modes, which is called as steel bar connection technology; the shearing force is borne by the bonding strength of the concrete of the bonding surface, the friction and shearing action of the key groove or the rough surface, the reinforcing steel bar and the pin bolt and shearing action; static friction can take up a portion of the shear force when the joint is under compression, a technique known as joint connection.
The connection technology of the steel bars is a key technology for transmitting tensile force in an assembled concrete structure, and the connection part firstly ensures that internal force can be smoothly transmitted under the action of load and secondly requires that the connection part has enough rigidity and good restoring force characteristic. At present, the sleeve grouting connection is mainly adopted, a single ribbed steel bar is inserted into a metal sleeve, grouting mixture is injected into the metal sleeve, and the mixture is hardened to form a whole body and realize the force transmission steel bar butt joint connection, namely the sleeve grouting connection for short.

The main reasons are: foreign matters exist in the sleeve, so that grouting is difficult; slurry leakage and defects caused by irregular operation in grouting; the accuracy of the component or the installation accuracy is poor, and the reinforcing steel bars are cut off and cut short when the component is forced to be in place. Once a construction defect occurs, it is very difficult to repair. Therefore, the construction defects are reduced by means of strict supervision, research and development of novel grouting equipment, optimization of construction process and the like.
