Tangshan, Hebei Province in 2012 builds high level 24 floor (H=96.8m) large bay, and to divide room flexibly multi-functional
Application office building building, the structural system of this building be in-situ casting concrete orthogonal spatial space lattice boxlike cylinder in cylinder
Structure.This building design the earliest is the cast-in-place concrete framework Core Walls Structure system of 18 layers, system of this area Areas of High Earthquake Intensity ground
District's (8 degree), its underground two-layer uses raft lamination foundation, only 18 layers on the ground, and owing to dead load is big, foundation bearing capacity is inadequate, need to beat
Stake improves foundation bearing capacity, after using concrete orthogonal spatial space lattice boxlike tube-in-tube structure, is increased by 6 by former 18 layers on the ground
Layer reaches 24 layers, and owing to dead load significantly declines, foundation bearing capacity also meets design in the case of not driving piles and requires, work
Journey practice the most fully proves the superiority of this type of structural system.Along with the development of economic construction, architectural engineering develops to assembled
It is industrialized needs.
And " Super High concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure and the making side the most declared
Method " and " assembly concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure and manufacture method ", in the two patent application
The former mainly introduces the building function advantage of this type of new concrete structure high-rise building, divides room flexibly such as large bay,
Each floor is all free stern layer to be easy to pipeline to install, reach the Architecture Policies of " be suitable for, economic, green, attractive in appearance ", and the latter is introduction
How this type of new concrete structure uses assembled integral construction method, i.e. its superstructure and the grid type framework of periphery to tie
Structure, how precasting yard press grid cell prefabricated after, install at the construction field (site), reach work by the construction technology of assembled integral
The requirement of industry.
Summary of the invention
The technical problem to be solved in the present invention is for the weak point existing for prior art, it is provided that assemble III type coagulation
Soil orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure and preparation method thereof.
A kind of assembling III type concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure and preparation method thereof is hereinafter referred to as
Assemble III type and assembling III type manufacture method, Super High concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure, mixing of it
Solidifying soil orthogonal-diagonal lattice hollow floor system, uses prefabricated mesh unit, transports job site assembly to and form entirety after precasting yard makes,
The construction method of this prefabrication and assembly construction, not only Prefabricated hollow grid cell few (3 kinds), maximum prefabricated unit reduces than traditional approach
50 ~ 70%, prefabricated component deadweight reduces the most accordingly, thus facilitates prefabrication and assembly construction construction to carry out smoothly.

Change into prefabricated.
The beneficial effect of employing the technical program:
Executive information systems, uses assembling III type concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure, both can subtract
The type of few concrete prefabricated unit of superstructure, can reduce again developed area and the deadweight of unit, the transport of favourable prefabricated unit with
Install.
The concrete empty stomach grid cell that precasting yard makes transports building site to, and after installing by construction drawing, at prefabricated list
Unit winds up and shelves steel bar truss floor support plate in grid, and will wind up while the splicing of upper and lower for stitching position string reinforcing bar being connected layer
Longitudinal reinforcement colligation is in the stirrup losing that winds up, and under without template premise, secondary casts high one-level concrete (has at splicing seams
Very small amount template).
The prefabricated mesh unit small-sized of superstructure, is not only easy to making transport but also can reduce heavy mechanical equipment accordingly, make this
Class new structural systen, without carrying out assembled integral construction under the conditions of increasing plant equipment, promotes architectural engineering industrialization
Development.
The prefabricated mesh minimum unit (C cell) of assembling type III, is the most single in orthogonal-diagonal lattice on an empty stomach grid cell
Unit, wherein A unit is C cell 4 times, and unit B is C cell 3 times, the division of superstructure precast concrete unit on an empty stomach, with C cell is
Elementary cell, thus prefabricated unit miniaturization, promote that this kind of concrete novel structural system is to assembled integral industrialization direction
Development.
In Super High and Tall Office Building are built, apply this type of new structural systen, its construction costs will float downward 20% with
On.
