The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
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 the tool-type connector with enclose purlin and be connected, steel structure girder 1 consists of side by side many shaped steel, in the present embodiment, be that three shaped steel form steel structure girder side by side, three shaped steel laterally interfix by junction plate, vertically are bolted and reach the length extension.The shaped steel radical that steel structure girder 1 includes, choose according to the actual loading situation.The end of steel structure girder 1 is provided with the combined type structural steel connecting member, and the combined type structural steel connecting member is combined by three triangle steel members, and purlin is enclosed in the connection of combined type structural steel connecting member, is provided with fish belly sill in the both sides of combined type connector and encloses purlin.
Referring to Fig. 2 and Fig. 3, the end of steel structure girder 1 is provided with a triangle steel member 33, triangle steel member 33 is isosceles right triangle, its hypotenuse connects steel structure girder 1, its right-angle side is distributed in both sides, with the right-angle side of two other triangle steel member 32, is connected, and two other triangle steel member 32 is also isosceles right triangle, three triangle steel members form an isosceles trapezoid key, and purlin 2 is enclosed in the bottom hypotenuse connection of isosceles trapezoid key.Triangle steel member 32 inside on both sides are provided with for locking the anchor lock of fish belly sill steel strand.The triangle steel member 32 on both sides is because the anchor lock need to be placed in inside, so be hollow structure in it.
The triangle steel member 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 whole Macintosh have very high structural stability and structural strength and reclaims and reuse.
Again referring to Fig. 3, triangle steel member 32 and triangle steel member 33 are formed by shaped steel combination, because shaped steel itself has certain width, so the outline of triangle steel member 32 and triangle steel member 33 is not proper right angled isosceles triangle, the outside of their bottom hypotenuse has chamfering, but its shaped steel inner side edge forms the right angled isosceles triangle of standard.
Referring to Fig. 4,
Extend laterally the both sides of the both sides triangle steel member 32 of Macintosh, for connecting other members, and is provided with antiskid and the plug 34 that increases resistance on the bottom hypotenuse of both sides triangle steel member 32.All the other are with embodiment 1.
Stack triangle steel member 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, described pattern foundation pit supporting structure supports with the tool-type connector of enclosure wall and has the following advantages with steel:
Three or a plurality of triangle steel member are carried out to assembling combination, form a new connector, can meet different needs.
Install with remove conveniently, recyclable recycle, reduction of erection time, reduction construction costs, purpose economizes on resources.
By the combination of tool-type connector, can increase the rigidity of support, can make to be connected with Macintosh to support and enclose effectively power transmission of purlin, and by the rigidity of self, equilibrium of forces in regulating.
Referring to Fig. 5, the hypotenuse of three triangle steel members is some or all of the non-standard 4 of connection, 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, meets the demand of difformity foundation ditch.
Referring to Fig. 6, the hypotenuse of three triangle steel members is some or all of the non-standard 41 of connection, and described non-standard is shaped piece, and shaped piece extends to both sides, widens the bearing surface of triangle steel member 33.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not subject to the restriction of above-mentioned example; that in above-mentioned example and manual, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
