Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Referring to Fig. 1, in the present embodiment, foundation ditch adopts inner supporting structure, inner support is the steel structure girder 1 to support, steel structure girder 1 two ends by tool-type connector with enclose purlin and be connected, steel structure girder 1 is made up of side by side many root type steel, be that three root type steel form steel structure girder side by side in the present embodiment, three root type steel interfix laterally across junction plate, are longitudinally bolted and reach length extension.The shaped steel radical that steel structure girder 1 includes, chooses according to actual loading situation.The end of steel structure girder 1 is provided with combined type structural steel connecting member, and combined type structural steel connecting member is combined by three triangle steel components, and purlin is enclosed in the connection of combined type structural steel connecting member, the both sides of combined type connector is provided with fish belly sill and encloses purlin.
Referring to Fig. 2 and Fig. 3, the end of steel structure girder 1 is provided with a triangle steel component 33, triangle steel component 33 is isosceles right triangle, its hypotenuse connects steel structure girder 1, its right-angle side is then distributed in both sides, is connected with the right-angle side of two other triangle steel component 32, and two other triangle steel component 32 is also isosceles right triangle, three triangle steel components form an isosceles trapezoid key, and purlin 2 is enclosed in the bottom hypotenuse connection of isosceles trapezoid key.Triangle steel component 32 inside on both sides is provided with the anchor lock for locking fish belly sill steel strand.The triangle steel component 32 on both sides is locked, so be hollow structure in it because inside needs to place anchor.
The triangle steel component 33 of steel structure girder 1 end is following structure, and referring to Fig. 3, its inside comprises the support bar 31 had for structural strengthening, makes overall Macintosh have very high structural stability and structural strength and reclaims and reuse.
Again referring to Fig. 3, triangle steel component 32 and triangle steel component 33 are formed by shaped steel combination, because shaped steel itself has certain width, so the outline of triangle steel component 32 and triangle steel component 33 is not proper right angled isosceles triangle, the outside of their bottom hypotenuse has chamfering, but its shaped steel inner side edge then forms the right angled isosceles triangle of standard.
Referring to Fig. 4,
The both sides of the both sides triangle steel component 32 of Macintosh extend laterally, for connecting other components, and the bottom hypotenuse of both sides triangle steel component 32 are provided with the plug 34 of antiskid and increase resistance.All the other are with embodiment 1.
Superposition triangle steel component can reduce the axial compression of enclosing purlin, especially can reduce fish belly sill and enclose purlin axial compression nearly 50%.
In the present embodiment, the tool-type connector of described pattern foundation pit supporting structure bracing members and enclosure wall has the following advantages:
Three or multiple triangle steel component are carried out assembling combination, forms a new connector, different needs can be met.
Install with remove convenient, recyclablely to recycle, reduction of erection time, reduction construction costs, economize on resources object.
By the combination of tool-type connector, can increase the rigidity of support, what can make to be connected with Macintosh can effective power transmission to supportting and enclosing purlin, and by self rigidity, equilibrium of forces in regulating.
Referring to Fig. 5, the hypotenuse of three triangle steel components is some or all of connection non-standard 4, and described non-standard is shaped piece, and shaped piece is quadrangle, can extend the transmission of power or change the direction of transfer of power, meeting the demand of difformity foundation ditch.
Referring to Fig. 6, the hypotenuse of three triangle steel components is some or all of connection non-standard 41, and described non-standard is shaped piece, and shaped piece extends to both sides, widens the bearing surface of triangle steel component 33.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not by the restriction of above-mentioned example; what describe in above-mentioned example and manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
