The rectangle connector is spliced by a plurality of little rectangular-shaped pieces.
The rectangle connector is spliced by steel.
The rectangle connector is processed by steel concrete
Fish belly sill comprises, lower edge beam, web member and the muscle that winds up; The lower edge Liangping is straight, and the muscle that winds up is an arc, and the lower edge beam joins with two ends of the muscle that winds up, and the web member lower end that a plurality of length are different is fixed on the lower edge beam, and the web member upper end contacts with the muscle that winds up, and forms a fish belly shape structure, and the muscle that winds up is applied with prestressing force.
Beneficial effect; Pattern foundation pit supporting structure according to the invention is used interior support connecting piece; Be applied in the pattern foundation pit supporting structure that supports in having, have power transmission direct, stressed evenly, connect reliable, install and remove convenient, recyclable advantage such as recycle, reach raising foundation ditch purpose of safety.
Description of drawings
Specify the present invention below in conjunction with the accompanying drawing and the specific embodiment;
Fig. 1 is the pattern foundation pit supporting structure partial schematic diagram.
Fig. 2 is a pattern foundation pit supporting structure partial points enlarged drawing.
Fig. 3 is a rectangle connector sketch map.
Fig. 4 is a rectangular-shaped piece arrangement sketch map under the another kind of situation.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1; Foundation ditch adopts inner supporting structure in the present embodiment, in be supported for steel structure girder 1 to support, steel structure girder 1 two ends are supported on through the rectangle connector encloses on the purlin; Steel structure girder 1 is made up of many shaped steel side by side; Support side by side for six roots of sensation shaped steel in the present embodiment, six roots of sensation shaped steel laterally interfixes through junction plate, vertically connects through bolt to reach the length extension.The shaped steel radical that steel structure girder 1 includes is chosen according to the actual loading situation.
Referring to Fig. 2 or 3; The end of steel structure girder 1 is connected with rectangle connector 2; Steel structure girder 1 and rectangle connector 2 are connected through bolt; Rectangle connector 2 another sides are connected and enclose on the purlin 3, and said rectangle connector four limits are made up of the steel splicing, and rectangle connector inside is provided with the diagonal angle support bar 21 that increases stability.Also be provided with one or more ground tackles 22 in rectangle connector inside in addition.Ground tackle 22 is used to connect the steel strand on the fish belly sill.
Rectangle connector 2 can be spliced by a plurality of little rectangular-shaped pieces.Adjacent little rectangular-shaped piece is connected to form a bigger rectangular-shaped piece through bolt each other,
The rectangle connector is spliced by steel.Also can be to interconnect by many shaped steel to form.
The rectangle connector is processed by steel concrete.Generally make rectangular framework earlier, build then.
Referring to Fig. 2, be provided with fish belly sill in the both sides of rectangle connector 2 and enclose purlin 4, fish belly sill encloses purlin 4 and comprises a lower edge beam 41, steel strand 42, web member 43.
Its lower edge beam 41 is assembled by the shaped steel material; Its steel strand 42 are made up of many high-strength underrelaxation steel wires, can adopt the plastic cement pipe box to play and irritate grease protection and isolation between the every steel strand.
Its web member 43 assembles wooden font or yi word pattern by the shaped steel material; Web member 43 is provided with on the string beam 41, and the two ends of steel strand 42 connect lower edge beam 41 two ends, and the middle part of steel strand 42 is supported by web member 43 and is the fish belly shape.Shaped steel and steel strand are assembled into the purlin that encloses of a fish belly shape structure, steel strand are applied prestressing force, this encloses the purlin span to reach increase, increases to enclose purlin rigidity the purpose of the horizontal distortion of control foundation ditch.
The material of lower edge beam 41 and web member 43 can be high-strength shaped steel, connects through welding or bolt between the shaped steel.Be separate between the many web members 43 or link together with tie rod.The two ends of enclosing purlin 4 at this fish belly sill need be provided with the strong point.Rectangle connector 2 is arranged on this strong point, plays the effect of this strong point of compacting.
Referring to Fig. 4, in some cases, a side of rectangle connector 2 (left side or right side) is provided with fish belly sill and encloses purlin 4, and steel structure girder 1 also has only one or more shaped steel to form.
Pattern foundation pit supporting structure according to the invention is used interior support connecting piece, is applied in the pattern foundation pit supporting structure that supports in having, have power transmission direct, stressed evenly, connect reliable, install and remove convenient, recyclable advantage such as recycle, reach raising foundation ditch purpose of safety.
Square key can be adjusted the stress point position of steel strand; Make stress point be positioned at waist rail section scope; Make the horizontal component of steel strand act directly on the waist rail section, utilize the cross section compressive strength of waist rail to bear most of horizontal component, so can significantly reduce the quantity of shearing bolt; Simultaneously, the steel strand stress point is placed in the waist rail section scope, avoided rectangle connecting key place to form couple, the stressed pattern of structure is more reasonable.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; The present invention does not receive the restriction of above-mentioned instance; That describes in above-mentioned instance and the manual just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
