The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figure 1, 2, the present embodiment provides a kind of assembling beam type sliding support hollow stair, and these hollow stair mainly comprise by 1 staristep forming of marking time, and specifically, this staristep is by a plurality of coherent complete integral structures of marking time and forming.The utility model has mainly been done to improve to staristep:
One, lightening grooves 2 is set on marking time.The effect of lightening grooves is, is subject to, on the basis of force intensity, to alleviate mark time concrete and amount of reinforcement, and then alleviates stair weight satisfied marking time.Lightening grooves arranges along tread run direction, and the structure of its setting has two kinds: a kind of is that the two ends, left and right of marking time are run through respectively at two ends, lightening grooves left and right; Another kind is that lightening grooves two ends are enclosed construction.The cross sectional shape of lightening grooves is triangular in shape, circular, square, rectangle or polygon; user can need to select the cross sectional shape of lightening grooves according to actual construction; the cross sectional shape that it should be noted in the discussion above that lightening grooves in Figure of description should not limit protection domain of the present utility model.In order further to improve the intensity of marking time, the present embodiment is at each interior steel hoop that is all embedded with of marking time.In order to improve aesthetic, the present embodiment is also provided with decorative pattern on 1 the left and right sides end face of marking time.
Two, staristep lower end is designed to sliding hinge seat structure.The lower end of the present embodiment staristep is set to the form of sliding hinge bearing, first it need to be provided with a right-angle steel bar 7 in building basic unit, these right-angle steel bar 7 upper surfaces are building coats structure, and the effect that right-angle steel bar is set is also to prevent from marking time the oblique sideslip of generation.The present embodiment is arranging on the basis of right-angle steel bar, and the mode that staristep lower end is designed to sliding hinge bearing has two kinds:
One
As shown in Figure 3, in staristep lower end, the last lower surface of 1 of marking time is provided with the steel plate 4 of the structure that is fixed as one with it, and these steel plate 4 width are identical with 1 width of marking time, at right-angle steel bar 7, with respect to the position of this steel plate 4, be provided with equally between steel plate 4, two block plates 4 and be equipped with graphite bisque.
They are two years old
As shown in Figure 4, in staristep lower end, the last is marked time and is provided with polyfluortetraethylene plate 5 between 1 lower surface and right-angle steel bar 7.
Further, staristep lower end the last mark time 1 lower surface and link position of right-angle steel bar are positioned under building coats, and building coats and staristep lower end the last mark time and between 1, there is gap 6 and be provided with polyphenyl plate in this gap.
Three, at the back of staristep (back to the one side of marking time), arrange and strengthen muscle 3.Strengthen muscle and have three at least, two both sides that lay respectively at staristep wherein, all the other strengthen muscle 3 and are arranged at these two and strengthen between muscle 3, and the gap between adjacent enhancing muscle 3 is equidistant.Strengthening muscle not only can provide the force intensity that is subject to of marking time, and has reduced span, has alleviated both sides load bearing beam power.
Manufacturing process of the present utility model is as follows: 1, cleaning is bought oil; 2, template is installed; 3, mounting framework built-in fitting; 4, concreting; 5, rest; 6, flour milling; 7, stream curing; 8, the demoulding; 9, check and repair, complete after above-mentioned technique, qualified products warehouse-in, defective superseded.Wherein, skeleton built-in fitting needs successively through reinforcing bar processing and cage of reinforcement moulding two step process preparations.
During the utility model entrucking transportation, should meet:
While 1. loading and unloading member, should consider car body balance; While 2. transporting, should take colligation fixation, prevent that member from moving or toppling over.3. the concrete to member corner portion or chain cable contact position, should adopt pad protected.4. in the process of stockyard and transportation, make stair keep flat as far as possible, in order to avoid local pressure is excessive, cause structural permanent damage; While 5. lifting upper transport vehicle, forbid producing any collision except inevitably colliding; 6. according to the practical experience of my company, in transportation, the speed of a motor vehicle should not surpass 60Km/h; While being 7. lifted into construction plant, accomplish to arrive i.e. use as far as possible, in order to avoid be exposed in air and rainwater, reinforcing bar is caused to corrosion.
The utility model mounting means is as follows:
Lifting location
(1) first check drawing, see that member is produced numbering, whether production model is corresponding with corresponding diagram;
(2) check whether member occurs phenomenon, especially the stair edges such as damaged;
(3) observe stair direction, result is according to the observation adjusted the direction of stair lifting;
(4) in the process of location, note the position of anchor bar, suitably adjust distance and make reinforcing bar not produce the situation of fighting;
(5) be lifted into relevant position, with expansion screw, probably locate.
Fixed calibration
(1) utilize the surveying and mapping tools such as transit, level gauge to observe the indices such as verticality, levelness, and finely tuned;
(2) record observed result, and guarantee that error is in 2 ';
(3) adjust the position of stair upper end preformed hole, make error drop to minimum.
According to above-described embodiment, just can realize well the utility model.What deserves to be explained is; under prerequisite based on above-mentioned design principle; for solving same technical problem; even if some that make on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme adopting is still the same with the utility model, therefore it also should be in protection domain of the present utility model.
