Beneficial effect, pattern foundation pit supporting structure inner support connector of the present invention, be applied in the pattern foundation pit supporting structure with inner support, have power transmission directly, uniform force, connection be reliable, install and remove convenient, the recyclable advantage such as to recycle, and reaches the object of raising deep pit monitor.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is pattern foundation pit supporting structure partial schematic diagram.
Fig. 2 is pattern foundation pit supporting structure partial points enlarged drawing.
Fig. 3 is rectangle connector schematic diagram.
Fig. 4 is rectangular-shaped piece arrangement schematic diagram in another kind of situation.
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 are supported on by rectangle connector encloses on purlin, steel structure girder 1 is made up of side by side many root type steel, support side by side for six roots of sensation shaped steel in the present embodiment, six roots of sensation shaped steel interfixes laterally across junction plate, is longitudinally bolted and reaches length extension.The shaped steel radical that steel structure girder 1 includes, chooses according to 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 bolted, rectangle connector 2 another side is connected to and encloses on purlin 3, described rectangle connector four limit is spliced by steel and is formed, and rectangle connector inside is provided with the diagonal strut bar 21 increasing stability.One or more ground tackle 22 is also provided with in addition in rectangle connector inside.Ground tackle 22 is for connecting the steel strand on fish belly sill.
Rectangle connector 2 can be spliced by multiple little rectangular-shaped piece.Adjacent little rectangular-shaped piece is bolted the larger rectangular-shaped piece of formation one mutually,
Rectangle connector is spliced by steel.Also can be interconnected by many root type steel to form.
Rectangle connector is made up of steel concrete.Generally first make rectangular framework, then build.
Referring to Fig. 2, the both sides of rectangle connector 2 are provided with fish belly sill and enclose purlin 4, fish belly sill encloses purlin 4 and comprises a lower-cord beam 41, steel strand 42, web member 43.
Its lower-cord beam 41 is assembled by section steel material; Its steel strand 42, are made up of many high-strength underrelaxation steel wires, plastic cement pipe box can be adopted to rise and fill with grease protection and isolation between every root steel strand.
Its web member 43, assembles wooden font or yi word pattern by section steel material; Web member 43 arranges on lower-cord beam 41, and the two ends of steel strand 42 connect lower-cord beam 41 two ends, and the middle part of steel strand 42 is supported in fish belly shape by web member 43.What shaped steel and steel strand are assembled into a fish belly shape structure encloses purlin, and to steel strand Shi Hanzhang, to reach increase, this encloses purlin span, increases and encloses purlin rigidity, controls the object of the horizontal distortion of foundation ditch.
Steel strand 42 are many, and steel strand 42 are made up of the reinforcing bar of many high-strength low relaxation.Smooth contact between steel strand 42 and web member 43, many steel strand 42 hierarchal arrangement.Steel strand 42 both ends are provided with Special ground tackle, adopt stretching method to steel strand Shi Hanzhang and are locked in special ground tackle 22, keeping its prestressing force.
The material of lower-cord beam 41 and web member 43 can be high-strength shaped steel, is connected between shaped steel by welding or bolt.Be separate between many web members 43 or link together with contact bar.The two ends of enclosing purlin 4 at this fish belly sill need to arrange 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, the side (left side or right side) of rectangle connector 2 is provided with fish belly sill and encloses purlin 4, and steel structure girder 1 also only has one or more shaped steel to form.
Pattern foundation pit supporting structure inner support connector of the present invention, is applied in the pattern foundation pit supporting structure with inner support, have power transmission directly, uniform force, connection be reliable, install and remove convenient, the recyclable advantage such as to recycle, and reaches the object of raising deep pit monitor.
Square key can adjust the stress point position of steel strand, stress point is made to be positioned at waist rail section scope, the horizontal component of steel strand is acted directly on waist rail section, utilizes the cross section compressive strength of waist rail to bear most of horizontal component, so can greatly reduce the quantity of shearing bolt; , be placed within the scope of waist rail section by steel strand stress point, avoid rectangle connecting key place and form couple, the stressed pattern of structure is more reasonable meanwhile.
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.
