Description
Technical field
A kind of design scheme of precast concrete hollow beam improves assembly efficiency, saves coagulation to reduce building self weight
Native dosage, and then Antiseismic building performance, external wall waterproof performance, a kind of constructure body structure system for building economy can be improved
System, and in particular to a kind of technology of the precast concrete hollow beam of efficient material-saving.
Background technique
In the situation that country widelys popularize assembled architecture, assembly concrete beam column is a kind of important skill in popularization
Art.However in development process, various precast beams expose varied problem, bring to assembled architecture development very much
The factor of puzzlement.Wherein, distinct issues are the most: the complex manufacturing technology of various composite beams, the self weight of itself is larger, and raw
Low efficiency is produced, is not only difficult to large-scale production, but also beam-column node is complicated, processing cost is high and final effect is not fully up to expectations.
And the precast beam of current most domestic, it is designed to solid beam body, most of composite beam has required out that muscle designs, not only not
Conducive to batch production, and concrete amount is big, and from great, transporting and hoisting is costly, and being unfavorable for saving material reduces cost.It is real
In the production of border, handwork is more, and is combined with precast concrete hollow beam each other and to fully rely on reserved steel bar and cast-in-place mix
Solidifying soil connection, usually occurs between precast concrete hollow beam and column, wall, reinforcing bar processing is very difficult, and then is difficult to protect
Construction quality is demonstrate,proved, is ensured enough so that integrally-built anti-seismic performance lacks, and user is caused to perplex.
It is exactly the connection type between precast beam and wall, column and precast beam that another, which perplexs many human factors,.Mesh
Preceding mainstream is connected with grout sleeve, is fixedly connected with reinforcing bar by grouting, to achieve the effect that assembled architecture is integrated up and down.
However, dosage is big since grout sleeve cost is higher, complex process is not easy to carry out many factors such as quality inspection, leads to construction cost
It is constantly promoted, it is difficult to obtain the approval of more users.And nationwide interior other connection types of application is less, therefore causes to fill
Overall cost with formula building is higher, it is difficult to Rapid Popularization, it is difficult to energy-saving and environment-friendly desired effect is played in national large area.
So invent it is a kind of can the technology of prefabricated hollow concrete beam commonly used in various engineerings throughout the country be that have very much must
It wants.
The beam column quality of building is not only that arrangement of reinforcement and thickness are determined, node and structure design also play a crucial role,
So in order to improve the component strength of beam column, and material utilization amount can be reduced, so design hollowcore precast beam is that construction wall is set
The method achieved many things at one stroke in meter.However domestic really fewer and fewer for the hollowcore precast beam technology of building construction, some products
Although hollow beam is all mainly used on large bridge, there is huge difference with precast beam used is built, therefore cannot claim
The hollowcore precast beams of concrete technology for house.Therefore in numerous building elements, standardization level is improved, saves material and province
Work is a huge problem, is objectively generally existing.
Summary of the invention
The present invention devises a kind of precast concrete hollow beam, and the precast concrete hollow beam technology is first by long line platform
The method of opening configures main reinforcement, replaces stirrup by the booster action of high grade fiber concrete, forms by interior vibration mold, can save big
Dimension material, concrete and artificial.The application of deformed bar and fiber concrete, so that precast concrete hollow beam becomes one
It can be with high efficiency production, high-strength light, the building construction member of materials saving.
The house of precast concrete hollow beam assembling, face wall the top for every standard room, by one piece of concrete
Native hollow beam 1 is to keep inner horizontal hole horizontal state to build, uppermost prefabricated after the completion of the building wall
There are " the horizontal elongated hollow hole between every two top column 12 " multiple tracks lateral apertures 3 inside beam.It can
In a manner of through rear drawing steel stranded wire, reinforce the anti-seismic performance of building.This precast concrete hollow beam that we develops, no
Address only solid beam from it is great, heat preservation it is poor, at high cost, hang it is motionless, draw lack the problems such as, and hollow structure reduce it is mixed
The heat transfer coefficient of solidifying cob wall body, reduces building lot load and based process expense.
As a kind of precast concrete hollow beam of the invention core product, apparent size is that height is a 0.3-0.8 meters of left sides
The right side, it is 1-7 meters long, 0.2-0.3 meters of thickness.The large scale prefabricated concrete hollow beam is led to based on the Basic Design of lateral aperture itself
Cross in lateral aperture increase posttensioned tendons mainly in combination with means, to increase the whole anti-seismic performance of collar tie beam, column and wall,
On the basis of increase overall cost is lesser, the larger promotion of house integral structure anti-seismic performance is realized.
The present invention does template in the design of precast concrete hollow-pole charge structure, according to concrete rib on the outer side of the wall, can be with
The outer formwork project amount of a large amount of roof overlapping layers is reduced, while more easily making exterior finish, reaches and exempts from effect of plastering.With setting
It is lifted in the lifting notch at precast concrete hollow beam both ends, using column concrete in precast concrete hollow beam water
The concrete interposing outbound formed in flat hole enhances the connection between precast concrete hollow beam, passes through dark collar tie beam and column is added
Reinforcing bar enhances, and pours overlapping layers after with the waterproof tongue on precast concrete hollow beam top and combines waterproof groove with bottom
In conjunction with wallboard, reaches and preferably combine effect and waterproof, shock resistance.
Present invention trial for the first time is up to long 7 meters wide 0.2-0.3 meters of monolith hollowcore precast concrete hollow beam with size,
Its hollow rate can be up to 45% or so, compare with the solid precast concrete hollow beam of area, from heavy and light half or so.Not only save
About nearly half concrete, saves half freight charges, also reduces a part of lifting expense and basic expense.
The thickness of 20-30 centimetres or so of precast concrete hollow beam itself is incorporated in filling in precast concrete hollow beam
Insulation system supplemented by thermal insulation material and column collar tie beam outer patch insulation board is breach, can prevent the beam column cold bridge generally occurred
Condensate problem, and reached good heat preservation and energy conservation effects.
The technical solution of the present invention is as follows: the invention realizes it to increase lateral aperture inside precast concrete hollow beam
Save the purpose of material loss of weight.3 He of lateral aperture that multiple tracks is arranged successively is preset in a kind of inside of precast concrete hollow beam 1
