The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Consult Fig. 1～shown in Figure 11, assembled-type house PC prefabricated units fabrication and installation structure of the present invention mainly supports fixed system, a demoulding Lift-on/Lift-off System, a template by a mounting limit system, and installs and ties link system, a leveling system and " I " type are hung nail consist of.
According to the prefabricated units working drawing, drawing is carried out Deepen Design, determine profile, size, the thickness of slab of member; Determine title, numbering and the quantity of member; Determine the thin section node way of prefabricated units;
According to each Components Shape characteristics, determine the assembling and mounting scheme of each member.Select to determine that lifting component and installation are with hanging nail, embedded sleeve barrel kind, position, quantity; And the contents such as the quantity of other reserving holes, built-in fitting, position.According to design scheme lifting component and installation process stress and matching used component and fitting are carried out mechanics check computation.
1) embedded sleeve barrel that utilizes different size is as linking connector, to prefabricated units lift, fix, mounting limit etc.For satisfying prefabricated part hanging and installing and using needs, pre-buried different size model straight screw sleeve in prefabricated units uses as lifting and installation drawknot.
The embedded sleeve barrel model mainly contains three kinds: M16 * 50mm, M14 * 50mm, M20 * 150mm, wall thickness 4mm.2 φ 10HPB300 Bar Anchorages of embedded sleeve barrel bottom welding, anchorage length 25d.
Wherein embedded sleeve barrel type selecting and function are as follows:
As shown in Figures 2 and 3, the first sleeve 11 in the mounting limit system: mounting limit sleeve, model is M16 * 50mm, be embedded in advance the top side facade of prefabricated units 101, use bolt and the first sleeve 11 that a spacing angle steel 110 is fixed on lower floor's prefabricated units 101 tops, itself and lower floor's prefabricated units 101 are adjacent to; When upper strata prefabricated units 102 are installed, itself and spacing angle steel 110 are close to, make upper strata prefabricated units 102 and lower floor's prefabricated units 101 plate faces on same plane, improve installation accuracy and speed.
As shown in Figure 4, support the second sleeve 12 of fixed system: member is installed and is fixedly connected with sleeve, model is M16 * 50mm, be embedded in advance respectively prefabricated units 101 bottoms and top, the second sleeve 12 of prefabricated units 101 bottoms is bolted complex number type steel bracket 121, fixedly PC prefabricated units 101 bottoms; Second sleeve 12 on prefabricated units 101 tops is bolted plural adjustable diagonal bracing 122, regulates prefabricated units 101 verticality, and carries out temporary fixed.
The 3rd sleeve 13 of demoulding Lift-on/Lift-off System: demoulding lifting sleeve, model is M20 * 150mm, uses bolt and the 3rd sleeve 13 will lift the steel plate connector and is fixed on the prefabricated units, is used for the prefabricated units demoulding and lifting.
Template is installed the quadruplet cylinder 14 to ties link system: template is installed pull bar is linked sleeve, model is M14 * 50mm, in PC prefabricated units and cast-in-place structural junction, when installing the cast-in-place structural template, Screw arbor with nut at both-ends and quadruplet cylinder 14 are connect, fixedly the drawknot template.
2) in conjunction with Fig. 5 and shown in Figure 6, adopt pre-buried special use " I " type to hang the mode of nail 15, be equipped with special hanger and carry out vertical handling installation exercise.Hanging nail 15 models is M20 * 240mm, and each hangs nail and adds 150 anchorings of 2 " U " type φ 10HPB300 reinforcing bars, anchorage length 30d 15 times.Hang nail 15 pre-buried installations and adopt supporting special glue ripple.
Hang nail 15 arrangement principle: because the prefabricated units size is larger, according to the profile characteristics, 3～4 suspension centres are set at the prefabricated units top.Generally at prefabricated units middle part inner side, according to the principle of hoisting point position symmetry, suspension centre is arranged at two ends, prefabricated units top to the prefabricated units center of gravity, and being arranged on has preferably position of sleeper or stressing conditions in the wallboard.
3) utilize built-in bolt sleeve to use as mounting limit.
Consult Fig. 2 and shown in Figure 3,2～3 of the pre-buried steel bolt sleeves of lower floor's prefabricated units 101 top side facades, when upper strata prefabricated units 102 are installed, straight spacing angle steel 110 is fixed by bolts to lower floor's prefabricated units 101 tops, and exceeds top 150mm.Install concordantly when upper strata prefabricated units 102 are installed along spacing angle steel 110 and lower floor prefabricated units 101 plate faces, the location is installed soon, efficient is high, has overcome the shortcoming that common field measurement efficient is low, error is large.
4) cooperate Fig. 7～shown in Figure 11, at the pre-buried steel bolt sleeve in lower floor's prefabricated units 101 tops: the 5th sleeve 16, adjusting bolt 160 is installed, as upper strata prefabricated units 102 leveling are installed and support.
According to the Components Shape rule, push up 3～4 of pre-buried M20 steel bolt sleeves at prefabricated units 101 plates, should locate the relevant position in upper strata prefabricated units 102 bottoms, the plate bottom surface is designed and produced into the plane.
When prefabricated units 102 are installed, at first install lower floor's prefabricated units 101, M20 standard bolt 160 is screwed in the 5th sleeve 16 on lower floor's prefabricated units 101 plates top, according to installed height mark at the bottom of upper strata prefabricated units 102 plates, that bolt 160 end face absolute altitude leveling are consistent.When upper strata prefabricated units 102 are installed, directly upper strata prefabricated units 102 are installed in bolt 160 tops, check again and detect upper strata prefabricated units 102 absolute altitudes, for the absolute altitude deviation, come adjusting elevation by heightening or turn down bolt 160 again.For bearing capacity at the bottom of prefabricated units 102 plates of enhancing upper strata, can establish 10mm steel plate 161 at upper strata prefabricated units 102 plate heelpieces during installation.
After cast-in-place structural concreting is finished, after cast-in-place structural can bear the member load, bolt 160 is unscrewed, shed the load of 102 pairs of lower floor's prefabricated units 101 of upper strata prefabricated units.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not consist of limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
