Further, above-mentioned support plate is placed on above installed anchoring piece.
Specifically, when above-mentioned support plate is selected as steel plate 112, the size model number of steel plate 112 selects 200*200*
14mm。
Further, when above-mentioned support plate is selected as angle steel 111, the size model number of angle steel 111 selects L90*90*
8。
Further, after above-mentioned support plate being placed on anchoring piece, it is also necessary to according to the elevation line popped up on wall into
After row correction, then reinforced.
It should be noted that when above-mentioned support plate is selected as angle steel 111, after should being corrected using horizon rule again
It is fixed.
Further, girder steel ontology 120 is H profile steel 121 or channel steel 122.Girder steel ontology 120 is welded on support element.
It is not only easy for construction by the way that girder steel ontology 120 to be welded on support element, and good integrity, entire interlayer knot
The stability of structure combined system is high.
Specifically, by girder steel ontology 120 according to the installation of wall upper control line it is in place after, the end of girder steel ontology 120 into
The measurement of two vertical direction of row influences the flatness of follow-up ALC floors 130 to prevent girder steel ontology 120 from installing out-of-flatness；
It is welded again after determining 120 position exact level of girder steel ontology.
Further, in the present embodiment, it is measured using 1m horizon rules.
In other alternative-embodiments, the above-mentioned measurement whether horizontal to 120 installation site of girder steel ontology can also be selected
Select other tools applicatory of this field.
By installing above-mentioned girder steel component so that multiple girder steel components form the frame for installing floor construction, and
Multiple girder steel components are located at preset elevation line, help to ensure that the entirety for the frame structure that entire girder steel component is formed is flat
Whole property improves advantageous guarantee for subsequent installation ALC floors 130.
Further, when being connected between girder steel ontology 120, by two ends cuttings at angle, it is two-sided full to carry out angle
Weldering.Please refer to Fig. 7, when selecting H profile steel 121, connected two H profile steels 121 use the two-sided full welds of angle, weld horizontal away from
It is equal to 2000mm from d.
Further, floor construction is mounted in the frame that steel construction is formed.Floor construction includes multiple ALC floors 130
And multiple fixing pieces.Multiple ALC floors 130 are mounted in frame.
ALC floors 130 are autoclaved lightweight concrete board, are one kind of high-performance steam-pressing aero-concrete.ALC plates
It is with flyash or silica sand, cement, lime etc. for main material, is molded by more aerocretes made of autoclave curing
Plank (includes treated reinforcing bar enhancing).ALC plates can not only do materials for wall, but also can do roof boarding, be a kind of superior performance
Building material.
In the present embodiment, above-mentioned ALC floors 130 select width for 600mm planks.
In the present embodiment, by selecting ALC floors 130, the matter of entire sandwich combined system can not only be met
Amount requires, and environment protecting and power-saving, can reduce the cost of entire sandwich combined system.
Further, the both sides of each girder steel ontology 120 are respectively provided with groove, each ALC floor 130 is fixedly mounted on
In groove.Notch is provided on girder steel ontology 120, ALC floors 130 are entered by notch in groove.The filling of multiple fixing pieces in
In groove, to ensure that ALC floors 130 are horizontal with top of steel.Wherein, fixed structure includes cement pressure plate 131 and fills out
Seam portion.Further, when ALC floors 130 are installed, ALC floors 130 need to cut 121 wall thickness of H profile steel.According to practical standard width of a room in an old-style house ruler
Very little interception corresponding length H profile steel 121.A part is cut off on the unilateral edge of a wing of 121 one end of H profile steel.It is after H profile steel 121 is in place and pre-
Steel plate 112 is buried to weld.It is caught in from 121 indentation, there of H profile steel in ALC floors 130.Continue next ALC floors 130 from H profile steel
121 indentation, theres are caught in, and each ALC floor 130 is drawn close naturally, are left no gaps.Reasonable Arrangement plank, cuts when insufficient
Except other planks, until being paved with.It is firm that 121 edge of a wing of H profile steel of excision is welded again, using special caulking agent joint filling.
Specifically, 121 side top flange of same span H profile steel is cut off into 700mm, notch is formed, so as to width 600mm
Plank is sequentially placed into from this notch in H profile steel 121.Since plank both ends are anchored at the groove position of H profile steel 121, plank peace
The tongue and groove (end needs three-sided cut) along two 7 × 60mm of lateral incision of plank using cutting machine is needed before dress, to ensure its surface and steel knot
Structure is concordant.After on board suspending to the steel construction that installation is complete, plank is sequentially placed into H profile steel at the position for cutting off the edge of a wing
In 121 notch, and ensure to put it is straight, it is seamless.The surrounding that every block of plank is filled in using timber wedge is used in plank top surface
Guiding ruler measures, and adjusts the wooden contract height, it is ensured that plank and (flatness≤3mm) after top of steel level, then use and cut
Cement pressure plate 131 clogged, finally use special jointing agent joint filling, reach and remove timber wedge after intensity, carry out last
Repairing and 121 edge of a wing of H shaped steel cut off early period welded again.
Compared to monolithic reinforced concrete structure, which can effectively shorten the construction period, reduce item
Mesh cost.Compared to traditional full steel structure, which can significantly reduce and construction technology quality is easily controllable.
While reaching interlayer ground and exempt from levelling, ALC plates itself are a kind of to have many advantages, such as lightweight, high-strength, green, energy saving new
Type construction material.Therefore, which passes through using so that green for New Building Materials while meeting quality objective
Colour circle is protected ideas of energy-saving and is carried out and implemented, and can significantly shorten construction period reduction project cost, has good warp
Ji property, generalization and social benefit.
