Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Consult shown in Fig. 1 ~ Figure 11, assembled-type house PC prefabricated units fabrication and installation structure of the present invention is hung nail to ties link system, a leveling system and " I " type form primarily of a mounting limit system, a support fixed system, a demoulding Lift-on/Lift-off System, a model sheetinstallat.
According to prefabricated units working drawing, Deepen Design is carried out to drawing, determine the profile of component, size, thickness of slab; Determine the title of component, numbering and quantity; Determine the detail treatment way of prefabricated units;
According to each Components Shape feature, determine the assembling and mounting scheme of each component.Selection is determined lifting component and is installed with hanging nail, embedded sleeve barrel kind, position, quantity; And other reserving holes, built-in fitting the content such as quantity, position.According to design scheme, mechanics check computation is carried out to lifting component and installation process stress and matching used component and fitting.
1) utilize the embedded sleeve barrel of different size as link connector, prefabricated units lifted, fixes, mounting limit etc.For meeting prefabricated part hanging and installing and using needs, pre-buried different size model straight screw sleeve in prefabricated units, is used as lifting and installs drawknot to use.
Embedded sleeve barrel model mainly contains three kinds: M16 × 50mm, M14 × 50mm, M20 × 150mm, wall thickness 4mm.Embedded sleeve barrel lower weld 2 φ 10HPB300 Bar Anchorages, anchorage length 25d.
Wherein embedded sleeve barrel type selecting and function as follows:
As shown in Figures 2 and 3, the first sleeve 11 in mounting limit system: mounting limit sleeve, model is M16 × 50mm, be embedded in the top side facade of prefabricated units 101 in advance, use bolt and the first sleeve 11 that a spacing angle steel 110 is fixed on lower floor's prefabricated units 101 top, 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 face in same plane, improve installation accuracy and speed.
As shown in Figure 4, support the second sleeve 12 of fixed system: Components installation is fixedly connected with sleeve, model is M16 × 50mm, be embedded in prefabricated units 101 bottom and top in advance respectively, second sleeve 12 of prefabricated units 101 bottom is bolted complex number type steel bracket 121, fixing PC prefabricated units 101 bottom; Second sleeve 12 on prefabricated units 101 top is bolted plural adjustable diagonal bracing 122, regulates prefabricated units 101 verticality, and carries out temporary fixed.
3rd sleeve 13 of demoulding Lift-on/Lift-off System: demoulding lifting sleeve, model is M20 × 150mm, uses bolt and the 3rd sleeve 13 to be fixed on prefabricated units by lifting steel plate connector, for the prefabricated units demoulding and lifting.
Model sheetinstallat is to the 4th sleeve 14 of ties link system: model sheetinstallat links sleeve to pull bar, model is M14 × 50mm, in PC prefabricated units and cast-in-place structural junction, when installing cast-in-place structural template, Screw arbor with nut at both-ends and the 4th sleeve 14 are connect, fixing drawknot template.
2), shown in composition graphs 5 and Fig. 6, adopt pre-buried special " I " type to hang the mode of nail 15, be equipped with special hanger and carry out vertical handling installation exercise.Hanging nail 15 model is M20 × 240mm, and each nail that hangs adds the anchoring of 2 " U " type φ 10HPB300 reinforcing bars 150 for 15 times, anchorage length 30d.Hang pre-buried installation of nail 15 and adopt supporting special glue ripple.
Hang nail 15 arrangement principle: because prefabricated units size is comparatively large, according to profile feature, 3 ~ 4 suspension centres are set at prefabricated units top.Prefabricated units center of gravity is generally in prefabricated units inside middle portion position, and according to the principle of hoisting point position symmetry, suspension centre is arranged at two ends, prefabricated units top, is arranged in wallboard and has sleeper or the good position of stressing conditions.
3) built-in bolt sleeve is utilized to use as mounting limit.
Consult shown in Fig. 2 and Fig. 3, the pre-buried steel bolt sleeve of lower floor's prefabricated units 101 top side facade 2 ~ 3, when upper strata prefabricated units 102 are installed, straight spacing angle steel 110 is fixed by bolts to lower floor's prefabricated units 101 top, and exceeds top 150mm.Install concordant along spacing angle steel 110 with lower floor's prefabricated units 101 plate face when upper strata prefabricated units 102 are installed, install location soon, efficiency is high, overcomes the shortcoming that usual field measurement efficiency is low, error is large.
4) coordinate shown in Fig. 7 ~ Figure 11, at the pre-buried steel bolt sleeve in lower floor's prefabricated units 101 top: the 5th sleeve 16, adjusting bolt 160 is installed, as upper strata prefabricated units 102, leveling is installed and supports.
According to Components Shape rule, prefabricated units 101 plate top pre-buried M20 steel bolt sleeve 3 ~ 4, bottom upper strata prefabricated units 102, this relevant position, place, is made into plane by plate floor design.
When prefabricated units 102 are installed, 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 plate top, according to installed height mark at the bottom of upper strata prefabricated units 102 plate, by consistent for the leveling of bolt 160 end face absolute altitude.When upper strata prefabricated units 102 are installed, directly upper strata prefabricated units 102 are arranged on bolt 160 top, then check detection upper strata prefabricated units 102 absolute altitude, for absolute altitude deviation, then carry out adjusting elevation by heightening or turn down bolt 160.For strengthening bearing capacity at the bottom of prefabricated units 102 plate of upper strata, during installation, 10mm steel plate 161 can be established at upper strata prefabricated units 102 plate heelpiece.
After cast-in-place structural concreting completes, after cast-in-place structural can bear component load, bolt 160 is unscrewed, shed the load of upper strata prefabricated units 102 pairs of lower floor's prefabricated units 101.
Below embodiment is to invention has been detailed description by reference to the accompanying drawings, and those skilled in the art can make many variations example to the present invention according to the above description.Thus, some details in embodiment should not form limitation of the invention, the present invention by the scope that defines using appended claims as protection scope of the present invention.
