Embodiment Construction
[0023] In order to explain the technical content, constructive features of the present invention, the embodiments, the following combined embodiments are described below, and the accompanying drawings will be described in detail.
[0024] reference figure 1 As shown, the preform member of the present invention includes two screw rapid splicing members including two bolt rods 1, two nuts 2, two links 3, two tutorial positioning cards 4 and a link reinforcing rib. 5, where:
[0025] The two links 3 are disposed in parallel, and the two end portions of the two links 3 provided in parallel are respectively provided with a nut body 2.
[0026] The bolt rod 1 is screwed onto the nut body 2 to screw the nut 6.1 reserved on the preform member 6; the bolt rod 1 is relatively loose to the screw bodies 2, so that it can be adaptable to it. And the positional deviation at the time of the buffer installation, since it is loose screw, in order to ensure the intensity of the connection, it can b...

The invention relates to a double-screw rapid splicing piece for a reinforced connecting rod between prefabricated concrete components, which includes a bolt rod, a nut body, a connecting rod, a supporting screw positioning card and a connecting rod reinforcing rib; Nut bodies are provided respectively; the bolt rods are screwed on the nut bodies, one end of the bolt rods is provided with a protruding operating head, and the other end of the bolt rods is provided with a concave operation slot; The group card on the root connecting rod, the middle part of the two group cards is provided with a concave bracket, and a compression spring is also arranged between the concave bracket and the convex operating head of the bolt rod; a spring is arranged between the two connecting rods. or a plurality of connecting rod reinforcing ribs, and the two ends of the connecting rod reinforcing ribs are provided with locking grooves for clamping the connecting rods. The invention can not only realize the reliable butt joint of the reserved nut cylinder on the prefabricated reinforced concrete member, but also can screw in quickly. Multi-directional splicing requirements.
Description
Technical field [0001] The present invention relates to the field of architecture, and specific relates to a prefabricated concrete structural reinforced link double snail fast splice. Background technique [0002] The assembled concrete member is divided into several components into several components in the factory. After the site, the assembly structure is assembled into a whole, and the assembled structure can achieve the same construction support quality. Due to the prefabricated process of assembled concrete components, its force steel can be set to be set. When assembling on-site, the neighbor assembled ingredients can be connected by the steel joint structure, which can be securely connected, reliable, and the construction is convenient and fast. At the same time, the connection between the connecting parts can also bear the load generated by the installation process before the pouring of the concrete, and the construction is safe and reliable. [0003] After the assembly...
