Description
Technical field
The present invention relates to building engineering fields, and in particular to a kind of building structure.
Background technique
Current building has common two kinds of shear wall systems, and one kind is concrete shear force wall, and one kind is steel plate concrete group
Combination shearing wall；
Concrete shear force wall be generally mostly it is cast-in-place after scene is wire-tie, site operation precision is low, speed slowly and not environmentally.
After structure reaches certain height, thickness of wall body is partially thick.Blocked up shear wall is not only constructed complexity, wasting space, and is led
Self weight is caused to increase, geological process increases；Furthermore the increase of shear wall's thickness, so that the rigidity of Core Walls Structure greatly improves, in order to full
Sufficient exterior frame column undertakes the requirement of story shearing force ratio, the rigidity that the section of outline border beam column will also increase therewith to realize inner cylinder and outline border
Matching, the overall cost of structure and scale are difficult to control at this time.
As country widelys popularize assembled architecture, steel plate combined shear wall is more and more widely used, steel plate combination
Shear wall is a kind of wall body construction as made of steel and Combined concrete, while having the excellent of steel member and concrete component
Point, the rigidity of concrete is big, fire resistance is good, the expense of initial cost and later maintenance is all lower, steel plate and Combined concrete
Resistance to compression, tension and the shear-carrying capacity that wall can be effectively increased make shear wall meet wanting for axial compression ratio with lesser wall thickness
It asks, wall thickness and dead load is effectively reduced, save space, reduce earthquake effect.Furthermore its fire prevention, heat preservation, soundproof effect and resistance to
Long property is good.Steel-concrete compound shear wall is maximized favourable factors and minimized unfavourable ones by giving full play to the respective advantage of steel Yu two kinds of materials of concrete；
But conventional steel plate concrete combined shear wall, concrete need cast in situs, are easy to produce hollowing, and scene
The problems such as that there are precision is not high for splicing, welding capacity is big, difficulty of construction is big.It is specific as follows:
1, it embeds steel plate and unilateral steel plate combined shear wall is applied to super-high building structure and is primarily present following deficiency: 1)
Since concrete is located on the outside of steel plate, in the case where large deformation, concrete slab may occur cracking and peel off, to the pact of steel plate
Shu Zuoyong weakens significantly, and ductility energy dissipation capacity of the shear wall under big shake effect is greatly reduced；2) shearing wall construction is more multiple
Miscellaneous, steel plate transport installation difficulty is larger, and scene needs formwork supporting plate, ties up the processes such as reinforcing bar, and construction is relatively difficult；3) concrete is opened
Split more difficult to control, crack is exposed to be difficult to avoid that, to influence normal use and durability.
2. the existing thin about 4mm of some type of steel plate shear force wall wall thickness, steel plate reinforcing rib, factory are utilized between two-sided steel plate
When processing, steel plate and reinforcing rib welding capacity are big, and due to that can deform after the thin welding of wall, it is difficult to guarantee flatness and dimensional accuracy；
When component conveying is to in-site installation, due to component precision problem, dislocation is relatively more when docking up and down, and separately plus steel plate need to be assisted upper
Lower wall welds, and the circle of whole cross section one need to weld entirely, and welding capacity is difficult to ensure greatly welding quality, is also easy to produce rosin joint, solder skip
Phenomena such as there are security risks, and since the thin site welding of wall can generate secondary deformation, influence the flatness of wall.
3. existing some type of steel plate shear force wall needs wallboard splicing at the scene to carry out a large amount of concrete after the completion and pours
It builds, site operation environment, safety and dust are unable to get good control, and environmental requirement is not achieved.On the other hand, due to wall
It is relatively thin, general 150mm of thickness or so, but depth commonly reaches 3-9m, therefore be not easy to vibrate in grouting, concrete casting
Afterwards, exhaust is insufficient easily there is the phenomenon that hollowing, causes grouting quality that cannot reach design requirement, influences safety, and scene fills
Slurry greatly relies on extraneous weather conditions, in case of sleet or extreme weather will be unable to carry out operation.
4. traditional steel plate shear force wall splices node up and down following two mode, and 1) welding manner；2) post-grouting anchors
Formula connection.The shortcomings that the first welding manner, is to need to be consolidated upper wainscot sheathing with additional connecting plate when in-site installation
It is fixed, infinite place device is docked up and down without dedicated, is positioned manually that precision is low, and low efficiency carries out a large amount of site welding after docking
It connects, finally also remove connecting plate, process is cumbersome and welding quality is difficult to ensure；Second of connection type, which only relies on, holds
The cohesive force and frictional force of tap position grouting material ensure the stress continuity of upper wainscot sheathing, and splicing node can not accomplish and wall
The equal strength of plate itself, and the node can not be suitable for skyscraper；Although additionally some steel plate shear force walls use spiral shell
The mode connect is tethered, but prefabricated positioning device, the connecting plate of docking need to be located by connecting wall at the scene not in factory up and down,
It is low that precision is positioned manually, low efficiency carries out grouting without grout hole after docking and guarantees the continuous proof strength of mixed mud.
The connection of steel plate combined shear wall and floor at present is a construction problem, since steel plate combined shear wall two is outer
Side is made of steel plate, and the rigid connection with concrete floor is difficult to realize, and the globality of floor not can guarantee.
