The pre-buried base of description of reference numerals: 1-, 2-K shape I steel composite structure, 3-i iron girder, 4-angle steel secondary beam, 5-steel plate panel, 6-guard rail, 7-parapet, 8-concrete floor, 9-square plate, 10-crotch, 11-embedded bar.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, first, protection canopy of the present utility model forms rectangular frame primarily of i iron girder 3 and angle steel secondary beam 4, and laying steel plate panel 5 forms protection canopy structure thereon.
As shown in Figure 2, the support mainly K shape I steel composite structure 2 of protection canopy structure of the present utility model, this K shape I steel composite structure 2 is fixedly connected on pre-buried base plate 1, and pre-buried base plate 1 is fixed on concrete floor 8.The section of encorbelmenting of protection canopy to be positioned at above parapet 7 and not to contact with parapet 7.
K shape I steel composite structure 2 is welded into K shape by 3 I16 i iron, a vertical i iron, two oblique i iron; Vertical i iron is vertically fixed on the square plate 9 of pre-buried base 1, and its top connects the i iron girder 3 of perpendicular layout; Wherein first oblique i iron one end is connected to vertical i iron middle and lower part, and the other end obliquely (be 40 ~ 50 ° with vertical i iron angle) is connected on concrete floor 8; Second oblique i iron one end is connected on first oblique i iron, and the other end obliquely (be 30 ~ 40 ° with vertical i iron angle) is connected to bottom i iron girder 3.
As shown in Figure 3, wherein, pre-buried base 1 comprises square plate 9 and embedded bar 11.Square plate 9 length and width 200X100mm, thickness 10mm, direction steel plate 9 welds a vertical i iron of I16 of K shape I steel composite structure 2, pre-buried 11 reinforcing bars of square plate 9 lower weld two Ф 16, reinforcing bar pre-buried 11 is in concrete floor 8 and arrange crotch 10 in end.
An embodiment of the present utility model: as shown in Figure 2, steel plate panel adopts 1.5mm thick cold rolled steel sheet, and steel plate panel lower berth L70*4 angle steel secondary beam 4, spacing 3mX0.75m, i iron girder 3 adopts I16 i iron, spacing 3m.The termination of i iron girder 3 is welded with the vertical i iron bottom of K shape I steel composite structure 2, i iron girder 3 bottom is welded with the oblique i iron of K shape I steel composite structure 2, the monolithic construction that i iron girder 3 can be designed to as Fig. 2 with the vertical i iron of K shape I steel composite structure 2.Arranging guard rail 6 apart from 100mm place, the section of encorbelmenting end (namely inside contracting 100mm), guard rail 6 adopts steel pipe to set up, scaffolding height 1.2m, and horizontal steel tube is respectively 0.6m, 1.2m apart from bottom.Vertical steel pipe spacing is not more than 2m.Inner face completely hangs Dense mesh screen.
