Description
Technical field
This utility model belongs to pattern foundation pit supporting structure and side slope protection field, particularly relates to a kind of connecting plate for special-shaped double-row pile.
Background technology
Along with the fast development of Process of Urbanization Construction and carrying forward vigorously of cities and towns My Perspective On The Co-building, the underground installation construction such as underground parking, underground commerce square, underground railway is required for carrying out pattern foundation pit supporting structure.Urban architecture foundation ditch the tightliest leads Urban Buried Pipeline Network facility (such as foggara, gas pipeline, communication cable etc.) and existing building, and level of ground water is higher.Due to the restriction of neighboring buildings environment, often cannot use surmount the soil nailing of property line, anchor pole carries out pattern foundation pit supporting structure, and cantilever pile is limited due to stiffness by itself, the supporting degree of depth is shallower, when combining inner support and using, substantial amounts of inner support not only affects operation in earthwork construction and hole, is also difficult to remove.And owing to level of ground water is higher, in addition it is also necessary to water-stop curtain wall of individually constructing, accordingly, there exist long in time limit, the shortcoming that cost is high.
And traditional double-row pile keeps at a certain distance away due to forward and backward campshed, and be attached by rigid frame mode, form the cantilevered portal frame structure with stronger rigidity, gradually popularization and application in the urban architecture foundation ditch of complex building environment, when needs carry out foundation ditch sealing, water-stop curtain wall of often constructing between forward and backward campshed or on rear side of rear campshed carries out foundation ditch sealing.Although traditional double campshed solves the support technology problem of city foundation ditch under complex building environment, and combine water-stop curtain wall and solve foundation ditch sealing problem, there is two significant drawbacks: typically little than front campshed many of the rear campshed stress of (1) double-row pile, rear campshed still uses deposited reinforced concrete pile to be greatly increased construction costs on but；(2) Double-row Piles Support foundation ditch needs individually construction when using waterproof of man wall sealing, and normally only considers its effect of intercepting water, and does not consider its gear soil effect, not only wastes material, increases cost, also extend the duration.
And use special-shaped double-row pile, i.e. front-seat employing bored concrete pile forms front campshed, heel row uses Soil-cement Wall interpolation shaped steel to form heel row wall, front campshed and heel row wall use rigit-frame beam or connecting plate to be attached the Novel double bank pilework formed, not only optimize acting on when native of heel row wall, also also serve as water-stop curtain wall, it is achieved gear soil unites two into one with water stopping function, both construction costs, again reduction of erection time had been saved.
Owing to the special-shaped front campshed of double-row pile and the connected mode of heel row wall directly affect its supporting effect, therefore, the connected mode of front campshed and heel row wall becomes the important component part of special-shaped Retaining Structure with Double-row Piles.
Utility model content
In order in campshed and the problem that is rigidly connected of heel row wall and connecting plate before solving special-shaped double-row pile, reinforcing bar inserts the difficult problem of passing through at shaped steel within the walls in heel row, this utility model provides a kind of connecting plate for special-shaped double-row pile.Use this connecting plate, both can avoid causing the main muscle of connecting plate cannot pass through a heel row wall hat beam difficult problem, the problem that simultaneously can solve to cause connecting plate and the shear-carrying capacity of heel row wall Guan Liang intersection and anti-bending bearing capacity to seriously undermine after shaped steel runs through connecting plate owing to shaped steel runs through connecting plate.
In order to solve above-mentioned technical problem, adopted the technical scheme that:
A kind of connecting plate for special-shaped double-row pile, including front-seat dowel crown beam, heel row wall Guan Liang, for connecting front campshed and the connecting plate of heel row wall and being built in heel row and be positioned at described heel row wall Guan Liang and the shaped steel of described connecting plate junction within the walls, it is provided with multiple first in described heel row wall hat beam and indulges muscle, ring muscle, big stirrup and little stirrup, described first indulges in the muscle length direction colligation respectively along the described heel row wall Guan Liang heel row wall hat beam in described shaped steel both sides, described ring muscle is set in outside described shaped steel, described big stirrup colligation is indulged muscle described first and is positioned in the extraneous part of flange width of described shaped steel, described little stirrup colligation is indulged in the part in the range of muscle is positioned at the flange width of described shaped steel described first, described little stirrup is pulled on described ring muscle near the side of described shaped steel set；It is provided with multiple second in described connecting plate and indulges muscle, little U-shaped main muscle and the main muscle of large U type, in the range of described little U-shaped main muscle is arranged on the flange width of described shaped steel, the main muscle of described large U type is arranged on outside the flange width scope of described shaped steel, the opening of described little U-shaped main muscle is anchored in described front-seat dowel crown beam, the closed end set of described little U-shaped main muscle is pulled on described ring muscle, the opening of the main muscle of described large U type is anchored in described front-seat dowel crown beam, and the closed end of the main muscle of described large U type is arranged in described heel row wall hat beam.
Described first indulges muscle is distributed in the both sides of described shaped steel, it is positioned at described the first of described shaped steel the same side to indulge muscle and be respectively arranged with multiple, this multiple described first indulges muscle and is divided into multiple row and arranges along the width of described heel row wall Guan Liang, and first indulges muscle and be divided into multilamellar to arrange along described heel row wall hat depth of beam direction described in each column.
The height of described little stirrup is the first maximum crust distance indulging between muscle described in same column, and the width of described little stirrup is the first maximum crust distance indulging between muscle described in homonymy.
Each ring muscle described is arranged along the short transverse of described shaped steel.
It is banded with the 3rd in described front-seat dowel crown beam and indulges muscle.
Due to the application of above-mentioned technology, successfully solve two hang-ups:
(1) a connecting plate shear-carrying capacity difficult problem is solved: owing to shaped steel penetrates the coupling part of connecting plate and heel row wall Guan Liang, the connecting plate of shaped steel both sides shear resistance in this place is significantly weakened, by the both sides of the shaped steel in heel row wall hat beam, little stirrup is set, solve connecting plate shear-carrying capacity problem in this place, by arranging big stirrup inside heel row wall hat beam, enhance connecting plate shearing resistance bearing strength in this place.
(2) a connecting plate anti-bending bearing capacity difficult problem is solved: owing to shaped steel penetrates the coupling part of connecting plate and heel row wall Guan Liang, main muscle in connecting plate is inevitably disconnected at shaped steel, largely reducing connecting plate anti-bending bearing capacity in this place, by arranging little U-shaped main muscle and little stirrup, and use ring muscle to carry out set to draw, ensure that the seriality of stress, solve a connecting plate anti-bending bearing capacity difficult problem in this place, the large U type through connecting plate of main muscle is set simultaneously, also enhances the bending bearing capacity of connecting plate.
