The installation node and installation method of the hinged concrete prefabricated component of the support

Abstract

The invention discloses an installing joint and an installing method for a support hinge concrete prefabricated part, and belongs to the technical field of constructional engineering. An embedded ironpiece is arranged at the bottom of the support end of the support hinge concrete prefabricated part, a hole is formed in the center of the embedded iron piece, and an inverted-frustum-shaped prefabricated hole is formed in the upper side of the hole; mortar is flatly laid on the top face, except a connecting hole, on the support position, for containing the concrete prefabricated part, of a support concrete part; a hoisting rod is adopted for hoisting the concrete prefabricated part and inserted in the connecting hole, and after a lifting hook is removed, the hoisting rod is rotated and adjusted to the installing height of the concrete prefabricated part, and after the mortar strength reaches 2MPa, the hoisting rod is removed; and connecting steel bars are inserted in the inverted-frustum-shaped hole and the connecting hole, and after concrete grouting materials are poured, the surface is subjected to sleeking. The hoisting rod capable of being repeatedly utilized is adopted in the installing joint and the installing method, the hoisting rod can be used as a hoisting ring and can also be used for adjusting the installing height and the installing precision of the concrete prefabricated part, steel consumption can be reduced, the installing work intensity is lowered, the installing efficiency, precision and quality are improved, and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a prefabricated concrete structure construction engineering, in particular to an installation method of a support hinged concrete prefabricated component. Background technique [0002] Concrete prefabricated components hinged by bearings, such as prefabricated concrete stair slabs, prefabricated concrete stadium slabs, etc., for the convenience of demoulding, lifting and installation, a variety of lifting rings or hanging nails and installation holes are designed. Low production efficiency, low installation accuracy, difficult quality assurance, and high construction costs. [0003] The prefabricated slab concrete stair sections of the National Standard Atlas "Prefabricated Reinforced Concrete Slab Stairs" 15G367-1; two vertical through holes are reserved at the hidden beams at each side slab end for installation; the second or third at each end Two hooks are pre-...

AI Technical Summary

Problems solved by technology

The method of this invention has the following problems: (1) only the vertical elevation of one side of the stand beam can be adjusted, and the side without the beam cannot be adjusted, and the vertical installation accuracy cannot be guaranteed; (2) the adjusting nut is pressed under the beam, and the upper left There are protruding steps to cover the side, the side operation space is small, and the adjustment operation is extremely inconvenient, especially when the viewing platform at the other end is installed, the operation is more difficult; (3) The stroke of the adjustment nut is small, and the adjustment of the adjustment bolt The installation accuracy requirements are extremely high, and a small error will cause the adjustment function to fail; (4) The adjustment bolts, nuts, and support pad iron embedded parts are only used to adjust the installation accuracy, and have no other purpose, which wastes material resources; (5) Drilling holes on the support of the concrete stand beams, and fixing the adjusting bolts in the holes requires a lot of work, arduous work, labor-intensive, and increased construction costs

[0006] In order to solve the problems of low production efficiency, low installation accuracy, difficult production and installation quality and high construction cost of the hinged concrete prefabricated components of the support, the number of demoulding hooks, lifting and lifting nails and installation holes should be reduced to achieve One thing is multi-purpose, and at the same time can significantly improve the installation efficiency and installation accuracy, so a new technical solution is urgently needed to solve these problems
