Description

A kind of assembling III type concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure and Manufacture method
Technical field
The present invention relates to technical field of buildings, particularly relate to a kind of concrete orthogonal-diagonal lattice space lattice, specifically refer to one Plant assembling III type concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure and preparation method thereof.
Background technology
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.
The technical solution of the present invention is to provide in following a kind of assembling III type concrete orthogonal-diagonal lattice space lattice boxlike cylinder Barrel structure, including tri-unit of A, B, C.
As preferably, wherein A unit is maximum unit, and C cell is minimum unit, and C cell is decussate texture, B Unit is made up of 3 C cell linear sequence, the groined type that A unit is made up of 4 C cell rectangular arrays.
As preferably, A unit is groined type shape structure, including winding up and lower edge.
As preferably, lower edge is groined type, and its cross section 250 × 150 is the most prefabricated, shear connector cubic block in the middle part of each node 250 × 250 × 100 is also prefabricated, and top reserves shear connector reinforcing bar.
As preferably, design section of winding up is 250 × 150, and prefabricated component top chord section is 250 × 70, winds up and highly subtracts Little by 80, its bottom reinforcement bars that winds up is prefabricated, and it is good that colligation reserved by top of winding up (at the most cast-in-place 8cm thickness) reinforcing bar, and the stirrup that winds up is the most pre- Stay colligation good.
As preferably, after A, B, C cell are respectively mounted, in each grid, shelve steel bar truss floor support plate, and The reinforcing bar that reserved by stitching position uses sleeve connection, and by upper reinforcement colligation of winding up in the stirrup reserved that winds up, Second time cast is more higher leveled concrete than Prefabricated hollow grid cell, i.e. forms assembling III type orthogonal-diagonal lattice space networks after maintenance Lattice boxlike tube-in-tube structure novel tall and slender structure system.
A kind of manufacture method of assembling II type concrete orthogonal-diagonal lattice space lattice boxlike tube-in-tube structure:
(1) prefabricated concrete orthogonal grid A, B, C cell are installed in place at the scene;
(2) in each concrete orthogonal grid, shelve steel bar truss floor support plate, and colligation top chord section internal upper part reinforcing bar and with set Cylinder splice bar;
(3) whole building second time casts concrete, i.e. forms superstructure and box structure is overall.
Described concrete orthogonal grid A, B, C cell make at precasting yard, and i.e. whole nodes of superstructure are by in-situ casting 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.
