Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention will be further described:
[0019] Such as figure 1 , figure 2 As shown, the present invention includes an upper prefabricated component 1, a lower prefabricated component 2, a long screw 3, a force transmission base plate 4, a thin steel pipe 5, a backing plate 6, longitudinal ribs 7 and nuts 8.
[0020] The upper prefabricated component 1 and the lower prefabricated component 2 in the present invention are common reinforced concrete anti-lateral force components, such as shear walls, columns, etc., and the connection of the present invention is applicable to vertical force transmission parts of longitudinal bars.
[0021] In the present invention, a long screw 3 is reserved at the upper part of the lower prefabricated component 2, and the long screw is welded or bound to the steel cage in the lower prefabricated component 2 to form a whole for prefabrication, so that the long screw 3 can fully an...

The invention proposes a dry-type connection device for prefabricated concrete components. The main stress-bearing longitudinal reinforcement parts of the upper prefabricated component are all welded to the force transmission base plate, and bolt holes are reserved on the upper part of the force transmission base plate to the side of the prefabricated component; the corresponding connection on the upper part of the lower prefabricated component A long screw is reserved in the position, and the long screw is welded or bound with the steel cage in the lower prefabricated component to form a whole for prefabrication; during on-site installation, the reserved long screw can pass through the upper reserved bolt hole from the side and connect with nuts. The invention adapts to the characteristics of easy industrial production of prefabricated concrete components, does not need grouting and cast-in-situ, completely avoids on-site wet work, and greatly improves the efficiency of on-site assembly and construction.
Description
technical field [0001] The invention relates to a prefabricated concrete component dry connection device, which belongs to the technical field of structural engineering. Background technique [0002] Prefabricated concrete structure refers to the standardized production of various components including prefabricated shear walls, prefabricated beams, prefabricated floors, etc. structure. The prefabricated components are industrially produced, and the manufacturing process can be more refined than ordinary cast-in-place components. It has the advantages of saving labor, fast construction progress, helping to realize building energy saving, convenient for industrial production and mechanized construction, etc., and adapts to the development direction of my country's construction industrialization. [0003] In precast concrete structures, the connection of horizontal joints between upper and lower members is a key technology in precast concrete structures. At present, the common...
