Description

The special structural section of earthquake proof construction

Affiliated technical field:

The utility model relates to a kind of structural steel, especially structure more science, more advanced, use steel still less, the load-bearing support force is stronger, pressures is not bad, indeformable, volume is little, in light weight, construction period short, lower, firmer, the longer service life of cost, have quakeproof and quake-resistant and resist other natural calamity and resist the novel earthquake-resistant building spy structural section that the terrorist destroys attack.

Background technology:

Building is in the world all generally used reinforcing bar (screw-thread steel) concrete structure at present, reinforced concrete structure is the progress that leap has been arranged than ancient brick wood building structure, and cost is low, sturdy and durable, long service life, but blemish in an otherwise perfect thing is: the reinforcing steel bar cage that is bundled into reinforcing bar, even its reinforcing bar is slightly many more again, cage is big again, there is not independently load-bearing support force yet, the fatal shortcoming of Here it is reinforced concrete structure, so its only reliable casting cement, yellow ground, after the concrete setting of stone, just have very strong load-bearing support force, so that gain in strength, so often need to use a large amount of steel concrete, cause bulky, not only stupid but also heavy, but the concrete after solidifying is not only hard but also crisp, can not be out of shape, in case impacted or collision deformation, concrete will be broken or be come off, and reinforcing bar also causes building collapsing with regard to losing the load-bearing support force.For example: " World Trade Organization's mansion " of the U.S. flies behind the bump owing to be subjected to the terrorist in 911 incidents, makes not only hard but also crisp concrete deformation broken or come off, and reinforcing bar causes mansion to collapse with regard to having lost the load-bearing support force.So in strong earthquake, often owing to strong vibrations with repeatedly rock and cause building deformation, make concrete broken or come off, reinforcing bar causes building collapsing with regard to having lost the load-bearing support force, has caused heavy losses for people's lives and properties.Present natural natural environment and climate changes abominable; also caused the frequent generation of earthquake and other natural calamity, so the destruction attack that people protect the lives and properties of oneself and carry out quakeproof and quake-resistant and resist other natural calamity and resist the terrorist with regard to the superpower building structure that needs the special structural section of employing novel earthquake-resistant building.

Summary of the invention:

Exist reinforcing bar to be bundled into the destruction attack that reinforcing steel bar cage does not have independently load-bearing support shortcoming and strengthens the quakeproof and quake-resistant of modern building and resist other natural calamity and resist the terrorist in order to solve existing reinforced concrete structure, I am according to modern house, the factory building structure and the viaduct of high buildings and large mansions and large-scale large span, the tunnel, subway, the highway bridge of large-scale large span and the building structure of railway bridge, and the use of the use of " I " shaped steel tendon concrete structure crossbeam and " I " shaped steel bone structure crossbeam, all adopted the load-bearing principle of " column supports very heavy ", through comprehensive study analysis and test of many times, invented more science of a kind of structure, more advanced, use steel still less, the load-bearing support force is stronger, press not bad, indeformable, volume is little, in light weight, construction period is short, cost is lower, firmer, longer service life, have quakeproof and quake-resistant and resist other natural calamity and resist the special structural section of novel earthquake-resistant building that the terrorist destroys attack and do the steel reinforced concrete structure support.

The technical scheme that its technical problem that solves the utility model adopts is: also do not have slim now on the market, small-sized, ready-made, end face becomes the special structural section supply of vertical bar shape " Shu " or " L " or " U " or " T " or " I " or " II " or "+" or vertical bar shapes such as " # ", we make with regard to the steel sheet of 2～3mm ourselves, also can select for use thicker steel plate to make according to the carrying weight load of building and the needs of support force, we are cut into plurality of specifications " wide " to steel sheet earlier, the steel plate bar of " narrow ", need to cut off by length again, length can be welded inadequately, if length is quite long, span is quite big, and we can cut off the alignment making with band steel plate bar, and the connecting hole that is used for leading to mutually when on the steel plate bar, being provided with a plurality of fluid concrete, we are according to the load-bearing principle of " column supports very heavy ", dexterously the steel sheet bar is stood vertically use, make its end face become vertical bar shape " Shu " shape, " Shu " shape steel plate bar that stands vertically like this, load-bearing and support force are all very strong, also can be pressed into the steel sheet bar or be welded into and make its end face become " L " shape or " U " shape, make such reinforcing bar structure, load-bearing and support force are just stronger, can also be on " Shu " shape steel plate bar that stands vertically or below again in the downhand welding steel sheet bar of " narrow " make its end face "T"-shaped, or on " Shu " shape steel plate bar that stands vertically and below steel plate bars of " narrow " in the downhand welding all, make its end face one-tenth " I " shape or make other shape as required again, make such reinforcing bar structure and just can carry quite heavy weight load and have quite great support force.Such reinforcing bar structure is applicable to the load-bearing support crossbeam of the bridge construction of house and high buildings and large mansions and large-scale large span factory building and viaduct and tunnel and subway and large-scale large span, is applicable to that also sewer, electric wire, gas flue and other the ground well on the highway supports crossbeam with the load-bearing of lid.If length, span and carrying weight load are all special big, we can form with a plurality of " I " shape, make its end face become " II " shape or " III " shape.Can also mix use with the reinforcing bar structure of other shape, intersect in length and breadth and be welded into nettedly, the reinforcing bar structure of making such combination is applicable to that the highway bridge of skyscraper and especially big building of other extra-high-speed and super-huge super-large span and the load-bearing of railway bridge building support crossbeam.，

We also make the reinforcing bar structure that end face becomes "+" shape with the steel sheet bar, make its four sides stressed evenly equal, be applicable to the load-bearing vertical support column of house and high buildings and large mansions and large-sized workshop and the pier column of viaduct and tunnel and subway and large-scale large span highway bridge and railway bridge, can also make reinforcing bar structure and other shape and structure that end face becomes " # " shape with the steel sheet bar.Be applicable to load-bearing vertical support column and the highway bridge of super-huge super-large span and the pier column of railway bridge of the especially big extra heavy building of extra-high-speed.

Can also between the reinforcing bar crossbeam, use " Shu " shape steel sheet bar that stands vertically to intersect in length and breadth as required and weld webbed structure stand, it is interconnected, support mutually, firm more solid, and the column of the crossbeam of reinforcing bar structure and reinforcing bar structure linked into an integrated entity, can weld or rivet.Make such reinforcing bar structural entity support, do not need with the weight load of concrete with regard to energy independent bearing monolithic architecture thing, and have superpower support force, the advantage of its reinforcing bar structure just here, also is the difference that is bundled into reinforcing steel bar cage with bar construction also.

Can also be at casting cement about the net-shaped steel bone structure support, yellow sand, stone, concrete are done floor or bridge floor.

In a word, the steel plate bar that stands vertically is wide more, thick more, bearing capacity and support force are just big more, reinforcing bar structure principle that we use is: crossbeam " perpendicular wide, horizontal narrow ", column is: " perpendicular, horizontal equating " is so we will select to use the thin and thick of steel plate and the shape of reinforcing bar structure according to the actual needs that building carry weight load and support force.But make so special structural section not only slow the but also quality of speed also cannot say for sure card, cost is also high, so various special structural section shape and plurality of specifications that we need above just being rolled in the time of will manufacturing in steel mill, and connecting hole that is used for leading to mutually and the screw thread that on special structural section surface, is provided with as screw-thread steel when on special structural section, being provided with a plurality of cast and mixing earth, to improve the supporting role that is connected of special structural section and mixed earth, make the reinforcing bar structure stand of earthquake proof construction of this special structural section, can play the quakeproof and quake-resistant effect effectively, length according to the building needs during building is cut off, length can be welded inadequately, the engineering construction duration can be shortened greatly, promote the engineering construction quality, increase building intensity, reduce building costs, really realize good and fast province again.

For the safety that guarantees building and quality and improve application life, we must embroider the iron on the special structural section reinforcing bar structure stand of making and thoroughly remove totally, and carry out antirust, anti-corrosive and handle, and quality comes first in our mighty construction plan.

Though existing reinforcing bar structural construction is durable in use, also has shortcoming, that will regularly eliminate rust exactly, antirust, do anticorrosion maintenance work, both pretty troublesome, and maintenance cost is also very high.

Handle properly for the intensity that strengthens special structural section reinforcing bar construction with antirust, anti-corrosive work is disposable, we can carry out prefabricated or use the template cast-in-place concrete with template, about special structural section reinforcing bar structure stand, about, front and back, inside and outside, local all fluid concretes that the space is arranged in template, and compress compacting, make the mutual jam-packed of reinforcing bar structure stand and concrete, be connected to each other the molten one that is, make a concerted effort to support, more sturdy and durable, can increase the intensity of special structural section steel reinforced concrete structure like this, again can be isolated special structural section reinforcing bar structure stand and air with concrete, play nonvolatil antirust, anti-corrosive effect, we use concrete just as auxiliary material, so materials are economized, volume is little, in light weight, the load-bearing support force is also stronger, even special structural section steel reinforced concrete structure is subjected to the sharp pounding of violent earthquake and rocks, or impacted or collision deformation causes concrete broken or come off, but special structural section reinforcing bar structure stand still has very strong bearing capacity and support force, also can only cause the local impaired distortion of building and can not collapse, can guarantee people's the security of the lives and property or suffer a loss less.

The beneficial effects of the utility model are: the reinforcing bar structure stand made from special structural section, replaced the reinforcing steel bar cage that reinforcing bar is bundled into, can be than original saving steel about 50%, save concrete about 30%, and bearing capacity and support force are all than original raising several times, and it is little to have a volume, in light weight, construction period is short, cost is lower, firm more solid, advantages such as longer service life, also save steel about 30% than present clean steel bone structure building, can also improve bearing capacity and support force, and can save the upkeep cost of antirust, anti-corrosive, really realize good and fastly economizing again.So we will be limited iron and steel resource and cement, yellow ground, stone, make full use of, build the needs that better more building satisfies modern people's life, for the mankind benefit, this also is great revolution and the innovation again on the human architectural history, has advanced international standard.
