Abstract
The invention provides a precast beam unit construction technology, with which the precast can be made in advance, and the time for one-piece casting on a construction site can be greatly saved, a beam shell can be a light and thin precast unit which can be served as a formwork, can be directly used as a ribbed formwork, and can be produced in large scale at a factory, the beam shell is concreted after being transported to the construction site to be assembled, and then forms a combined structural unit. The construction speed is fast, and the formwork is free from being supported on site. Building-in reinforcement stirrup in the beam shell can ensure the structural stability of the whole precast beam unit during the transportation and the like, which is suitable for second casting on site, and the reinforcement stirrup still can play its original role after the beam shell is installed in a building and the construction is completed.
Description
Technical field
The present invention relates to a kind of construction technology of prefabricated units of building, be specifically related to a kind of precast beam unit construction technology that is used for building.
Background technology
At present, building adopts reinforced concrete structure mostly, post, beam.Connected node globality between wall and the plate is strong, has good shock resistance.But the building of reinforced concrete structure needs on-the-spot reinforcing bar and the concreting arranged, needs the construction of a large amount of workmans and device context.In addition, before the concreting, need set up template; Need to wait for the regular hour after building, treating that concrete reaches after the enough intensity could stripping, just can adhere to construction equipments such as scaffold.
Prefabricated units can centralized production, and overall package is carried out at the scene of transporting to again, has saved the time of solidifying of poured in place concrete, improves construction speed, and can reduce field worker and amount of equipment, saves cost.Normally used precast beam unit waters and builds up an integral body, and the scene transported to again is connected with other structural element.Such precast beam unit and other structural element jointing place intensity are lower, and the whole shock resistance of building is relatively poor.
The inventor has proposed a kind of follow-on precast beam unit through studying for a long period of time, and this member adopts semi-closed structure, and internal fixation has reinforcing bar, can have good seismic resistance through all the other the structural element monobloc casts with building of building at scene.
Summary of the invention
The object of the present invention is to provide a kind of precast beam unit construction technology, adopt a concrete prefabricated semiclosed hollow housing and an on-the-spot structural element monobloc cast that has reinforcing bar, take into account prefabricated and advantages antidetonation two aspects.
For achieving the above object, technical scheme of the present invention is: a kind of precast beam unit construction technology, may further comprise the steps,
The first step is made precast beam unit in batches at manufacturing field;
Said precast beam comprises beam housing and stirrup, and said beam housing is semiclosed housing, and said stirrup is imbedded in the beam housing, and said stirrup not inlet part protrudes in the opening surface of beam housing;
In second step, precast beam unit is transported to the job site;
The 3rd step is with the precast beam unit location and installation;
The 4th step, main muscle is installed in precast beam unit, be connected with main muscle with the reinforcing bar of the structural element of precast beam unit joint;
In the 5th step, in the beam housing, carry out the concrete spouting construction.
When adopting technique scheme, the beam housing be can the double as template frivolous prefabricated component, can directly use as non-dismantling formwork, can be by plant layout production, transport to on-site consolidation concreting more later on, form the fabricated structure member.Speed of application soon, does not need on-the-spot supporting template.In the beam housing, bury stirrup underground and can guarantee the structural stability of whole precast beam unit in processes such as transportation, be fit to on-the-spot secondary and build, after installation and construction finished in building, described stirrup was still brought into play its due effect.
Further, stirrup is provided with the sealing outer ring in the said first step.
Further, the cross section of said beam housing is " U " shape, and said sealing outer ring is square.
Further, comprise through connecting the plural precast beam unit that draw-in groove connects in the 3rd step.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is the sketch map of a kind of precast beam unit construction technology of the present invention embodiment.
The specific embodiment
As shown in Figure 1, a kind of precast beam unit construction technology of the present invention may further comprise the steps,
The first step is made precast beam unit in batches at manufacturing field;
Said precast beam comprises beam housing 1 and stirrup 2, and said beam housing 1 is semiclosed housing, and said stirrup 2 is imbedded in the beam housing 1, and said stirrup 2 not inlet part protrudes in the opening surface of beam housing 1;
In second step, precast beam unit is transported to the job site;
The 3rd step is with the precast beam unit location and installation;
The 4th step, main muscle is installed in precast beam unit, be connected with main muscle with the reinforcing bar of the structural element of precast beam unit joint;
In the 5th step, in beam housing 1, carry out the concrete spouting construction.
The cross section of above-mentioned hoop beam housing is " U " shape, and said stirrup is provided with square sealing outer ring.
During use, in advance that this precast beam unit is concentrated prefabricated, form a semiclosed housing that has stirrup 2.Wherein stirrup 2 plays and supports and the effect of antitorque tension after 1 moulding of beam housing.When transporting, lifting, build, play the effect of brace summer housing 1.But whole beam housing 1 also double as beam forms uses, and need not to take mould and form removal, also need not the metope maintenance.Directly beam housing 1 is connected with on-the-spot construction member and fixes, concreting in beam housing 1 again, obtain with the construction member of building for example: post, plate etc. connects into " precast beam " of an integral body, has overcome the relatively poor weakness of traditional precast beam shock resistance.
Above-described only is preferred implementation of the present invention; Should be understood that; For a person skilled in the art, not breaking away under the prerequisite of the present invention, can also make some distortion and improvement; These also should be regarded as protection scope of the present invention, and these can not influence effect and practical applicability that the present invention implements.
