Abstract
The invention provides an arch crown house building technology specific to the defect of short service life of a current building. Through analytic demonstration, a conclusion that a major factor leading to too short service life of the building is the structure of the building instead of building materials. The decisive factor restricting the service lives of all the current buildings is that top plates are of flat tops. The top plates of the buildings are designed to be arch-shaped by using the load carrying principle of an arch crown in order to fulfill the aim of prolonging the service life. The top plates of the buildings are designed into double-layer steel ribs of which the lower sides are arc-shaped and the upper sides are planar. The arching height is 50-60 centimeters, and concrete is cast in situ. According to prediction, the service lives of arch-shaped buildings are prolonged by at least three times in comparison to flat-top buildings, being over 200 years. In existing buildings, arch-shaped steel frame support top plates are still designed by using the principle of arch top load bearing, thereby reducing the load of top plates, preventing the top plates from sinking, and fulfilling the aim of prolonging the service lives of the buildings. According to prediction, the service lives of the buildings can be prolonged to 200 years or more after support of arch-shaped steel frames.
Description
Technical field:
Field of house buildings
Background technology:
At present, building constructions is divided into highrise building and non-highrise building substantially.Structure has frame construction, also has brick mix structure.Top board has reinforced concrete cast-in-situ top board, also has precast floor slab.Highrise building is pure frame structure, casting top slab, but not the situation of highrise building is just more diversified, has frame construction, also has brick mix structure, have casting top slab, also have precast floor slab.But the top board in all houses has a common feature---flat-top, house section is rectangle.
At present, the design life of highrise building, substantially between 70 years-100 years, but not the service life of highrise building is but between 50 years-70 years.
Summary of the invention:
At present, the room rate in China one class city, every square meter more than 20,000 yuan of RMB, this just illustrates: the crowd of general middle and low income, and all one's life will be house and painstaking busy, be in debt even throughout one's life and be difficult to repay.Make great efforts the house of gained with lifetime, but only 70 years its service life, children will be house and throughout one's life painstaking again afterwards, be house and living exactly as people.
The author can also have ability to change room rate, to alleviate the economic pressures that people bring because of house-purchase.But problem to be solved by this invention is: the structure of transformation building, changes the moulding in house in other words, thus reaches the object extending building service life, extenuates the financial burden that people bring because of house.
Get off, we first analyze the principal element affecting the building life-span.We know, the primary building material of building is: steel, concrete and brick (because door and window, powder painting, decoration etc. can not affect its life-span, so do not consider).As everyone knows, steel are rolled in concrete, lose wind and rain, can not be corroded, so steel are not the principal elements affecting its life-span.Cement and goods thereof---concrete characteristic is: firm durable, is the best material choosing of civil construction and hydraulic engineering.Although the invention time of cement is not very long, also there is the history of nearly two a century, also do not have material to prove cement and goods---concrete thereof so far, will weathering after the several years, concrete loses its firm durability, so neither affect the principal element in building life-span.As for brick, we know, Qin brick and Han tile still has preservation, and the Xi'an Great Wild Goose Pagoda built before more than 1,000 year also stands intact so far, and this is enough to illustrate, brick is not also the principal element affecting its life-span.Moreover the skeleton of highrise building is not brick, but the beam and column poured into a mould by steel concrete, brick is only for short covering and partition wall.
As can be seen here: all building materials of building all can not restrict its too short service life.What does is the restraining factors that so the building life-span is too short on earth? the author is through long-term observation, analyze, through proving the conclusion that draws be: building life-span too short restraining factors are not at building materials, but the structure of building, problem goes out at top board in shape---flat-top.We know, no matter are precast floor slab or casting top slab, by steel concrete gelling, all roofs are flat-top, and house section is rectangle.
We know, certain weight had by oneself by top board, and nature will place some article within doors, and people must be movable in doors, and nature can produce some vibrations.Above-mentioned all weight and vibrations jointly apply pressure to top board downwards, cause top board to sink year by year, although sinking watching and slowly, amplitude is very small, is not easily discovered, and its sinking is inevitable.Passing in time, the amplitude of crushing must increase, when it sinks to acquiring a certain degree, top board just there will be crackle, and continuation is in time passed, the further increase of amplitude of crushing, crack also will be increasing, and when it exceedes certain limit, top board will can't bear the heavy load, there is the possibility rupturing and drop at any time, so the life-span of building terminates at this point.
Since the cause of disease finds, remaining issues is suited the remedy to the case exactly, seeks the scheme solved.As everyone knows, The Zhaozhou Bridge is built between Sui great Ye, about 605 years Christian eras, apart from the history of modern existing more than 1400 year, goes through big flood many times and earthquake, also stands intact so far.So why like this is The Zhaozhou Bridge firm durable? I wants the design science except bridge, builds rationally, and the vault factor that to be it important.May well ask, can it adhere to today as if not vault?
Vault is as Changhong, and in inside and outside two arcs, inner arc is little and outer arc is large.The weight of carriage, pedestrian and the vibrations produced thereof, add the deadweight of bridge, jointly applies pressure to bridge downwards.Those vibrations and Action of Gravity Field, when bridge, are squeezed into just as chock, are made vault press tighter and tighter.I thinks, does not is not this that vault can the principle of load-carrying even if larger pressure can not make bridge breaking subside?
Since vault can load-carrying, why not the top board of building is designed to vault, thus solves building life-span too short defect?
Does the measure that some can be taked to remedy, extend its application life about built existing building? be fine.The principle of vault load-carrying can be utilized equally, at top design one group of arch-shaped steel frame in house, roof supporting.
Detailed description of the invention:
Building is built, and top board should be designed to vault.Springing height can select 50-60 centimetre, and cloth double steel bar answered by top board, and lower floor is arc, and upper strata is plane, and each layer steel are crisscross to be reticulated, and muscle distance should between 18-20 centimetre.Allocation of steel: arch muscle 12, other muscle 10, the thickness of top concrete should select 12 cm, and arch punching block can be selected during building to support, and because punching block can repeatedly use, saves building costs.
Prediction, the application life of vault building at least extends more than three times than flat-topped building, should more than 200 years.
The shortcoming of this building is: the weight of building significantly increases, so in the design, basis and beam column should rationally be strengthened.
About built existing building, still utilize the principle of vault load-carrying, design one group of arch-shaped steel frame on roof, play roof supporting, decompose top board load-bearing, stop the effect of crushing, thus reach the object extending building service life.
On two leg tops, room, at interval of about 30 centimetres, spile and insert the suitable reinforcing bar a of model, paste the wall reinforcing bar b that the model of welding one about 50-60 centimetre is moderate respectively at the two ends of reinforcing bar a downwards, then weld the angle steel of a suitable types and length in the lower end level of reinforcing bar b, at interval of about 30 centimetres on two corner steel, the arch channel-section steel that corresponding welding one row model is suitable, building top board must be close in the top of arch form channel-section steel, forms one group of arch-shaped steel frame, to the upwards support that top board is powerful.In addition, arch channel-section steel can suitably weld several lacing wires, play stable steelframe.
Need to illustrate a bit, all steel should carry out antirust treatment, can prop ups if desired and be molded as cavity, with foam-filled, form a reinforced foam body in the chamber under arch-shaped steel frame, protect steelframe, do not make the effect of corrosion.
Certainly, also can according to the architectural feature of building, joint bar aperture can cloth about 50-60 centimeters under leg top, room, and such horizontal corner steel just directly can weld with horizontal slotting reinforcing bar a; Optionally also can save horizontal corner steel, arch channel-section steel, directly be welded on horizontal slotting reinforcing bar a, so not only saving of labor but also save material.
Can also, according to the hobby of people, be designed to by arch-shaped steel frame trapezoidal, herringbone or other shapes, can play roof supporting equally, decomposes top board load-bearing, stop the effect that it sinks.
There is the technology of arch-shaped steel frame roof supporting, the gravity originally independently born by top board and vibrations, can steelframe have been passed through, its gravity and vibrations are passed to room leg, plays roof supporting, alleviate top board load, stop the effect that it sinks, thus reach the object extending the building life-span.
After arch-shaped steel frame supports, be equivalent to set up a leg in the middle of house, reduce by half just as house span, reduce by half so house top board is stressed, and weight arm also reduces by half, because weight arm reduces by half, so the weight capacity multiplication of top board.Comprehensive various factors prediction, after arch-shaped steel frame supports, the service life of building should extend to 200 years or more.
