And the duration for setting up full framing etc. and expense can be greatlyd save, to often be used in Bridge Design construction.
But existing cantilever box girder construction Hanging Basket is suitable only for the box girder webs construction of single box single chamber structure type.Such as,
Chinese patent CN1916289A discloses a kind of Diamond-Shape Form Traveler, and main couple uses diamond structure, passes through between two Pin main couples
Frame, lower frame, front baffle and afterframe connect integral in connection.However as greatly developing for national communication, high-speed iron
Various bridge for needing to build can be encountered in the process of construction of road, and more than 100 meters of two chamber three-dimensionals are reached for main spanning diameter
The continuous cantilever box beam of pre-stress concrete variable cross-section, above-mentioned diamond shape main couple cannot be applicable in.
Utility model content
The purpose of this utility model is in view of the problems of the existing technology, to propose in a kind of cantilever box girder construction Hanging Basket
English truss, the biggish continuous cantilever box beam of main spanning diameter can be applicable in.
The purpose of this utility model is achieved through the following technical solutions:
The utility model provides the English truss in a kind of cantilever box girder construction Hanging Basket comprising:
Brace, vertical bar, stringer and transverse truss；
The brace be two, one end of two braces is fixed together, and the other end connect with stringer respectively, with indulge
Three-legged structure is formed between beam；
The vertical bar is located between two braces, and upper end is connected with two braces, and lower end is connect with the stringer；
The transverse truss is arranged between two Pin English trusses, with the connectors of vertical bar two sides with shellfish thunder pin connection one
It rises.
It is highly preferred that the three-legged structure formed between two braces and the stringer deviates the center of the stringer.
It is highly preferred that distance of the upper end of the transverse truss side apart from the vertical bar upper end is H1, the transverse truss other side
Distance H2 of the upper end apart from the vertical bar upper end, wherein H1 > H2.
It is highly preferred that be provided on the stringer three groups for anchoring through-hole, wherein first group of through-hole is close to English truss
Tail end, second group of through-hole be located at the rear middle part of English truss, and third group through-hole is close to the front end of English truss.
It is highly preferred that the transverse truss includes two cross bars disposed in parallel and is fixedly connected between two cross bars
Multiple tripods.
It is highly preferred that the brace is formed by channel steel Two bors d's oeuveres.
The utility model has the following technical effect that it can be seen from above-mentioned the technical solution of the utility model
The utility model is by way of English truss, in the case where satisfaction equally pours working area, because of suspention
The torque that template is born can be smaller, therefore can guarantee that the English truss is more firmly secured to the continuous beam poured
On, and then ensure that continuous beam does not pour the safety of the operation of part.It can be seen that the utility model can be applicable in main spanning
The biggish continuous cantilever box beam of diameter.
Detailed description of the invention
Fig. 1 is the main view of the English truss of the utility model；
Fig. 2 is the side view of the English truss of the utility model；
Fig. 3 is the utility model service condition schematic diagram.
In attached drawing:
English truss 1, anchor system 2, continuous beam 3, end template 4；Brace 11, vertical bar 12, stringer 13, transverse truss 14；
First group of through-hole, 131, second groups of through-holes 132, third group through-hole 133.
Specific embodiment
The technical solution of the utility model is described in further details below with reference to Fig. 1 to Fig. 3.
Embodiment one
The utility model provides the English truss in a kind of cantilever box girder construction Hanging Basket, structure such as Fig. 1 and Fig. 2 institute
Show, which includes: brace 11, vertical bar 12, stringer 13 and transverse truss 14.
One end of two braces 11 is fixed together, and the other end of two braces 11 is connect with stringer 13 respectively, with
The three-legged structure formed between stringer 13.Vertical bar 12 is located between two braces 11, and upper end is connected with two braces 11,
Lower end is connect with stringer 13.The connector Bei Leixiao between two Pin English trusses 1, with 12 two sides of vertical bar is arranged in transverse truss 14
It links together.
Suffered bending moment is smaller when in order to make English truss suspension hold the overarm of template, and the position of above-mentioned vertical bar 12 exists
The side at 13 center of stringer, that is to say, that the center of the position deviation stringer 13 of above-mentioned vertical bar 12 or two braces 11
The three-legged structure formed between stringer 13 deviates the center of stringer 13.
To avoid welding stress from concentrating and guaranteeing that triangle main truss 1 is more firm, transverse truss 14 is inclined at adjacent perpendicular
Between bar 12, such as: set distance of the upper end of 14 side of transverse truss apart from 12 upper end of vertical bar as H1, the upper end of the another side of transverse truss 14 away from
From 12 upper end distance H2 of vertical bar, then H1 > H2.
Above-mentioned transverse truss 14 include two cross bars disposed in parallel and be fixedly connected between two cross bars multiple three
Corner bracket.
Above-mentioned brace 11 is formed by channel steel Two bors d's oeuveres.
The end of brace 11 and vertical bar 12 is fixed with set, and the two sides of set are welded with connector obliquely, and brace 11 is logical
It crosses the connector and vertical bar 12 is fixed.
As shown in figure 3, be provided on above-mentioned stringer 13 three groups for anchoring through-hole, wherein first group of through-hole 131 is close to three
The tail end of angle truss 1, second group of through-hole 132 are located at the rear middle part of English truss 1, and third group through-hole 133 is close to English truss 1
Front end.Penetrating anchoring piece 2 by first group of through-hole 131 and second group of through-hole 132 can be fixed on one end of English truss 1 continuously
On beam 3.Penetrating anchoring piece 2 by third group through-hole 133 can be hung in the overarm for being used to hold end template 4 on English truss 1.
The vertical bar of English truss is acted on poured when in use by the utility model by way of English truss
Continuous beam on, so that template suspension partial action equally pours operation in less a part of English truss, meeting
, can be smaller using the torque that the English truss of the utility model is born in the case where area, therefore can guarantee the triangle purlin
Frame is more firmly secured on the continuous beam poured, and then ensure that continuous beam does not pour the safety of the operation of part
Property.It can be seen that the utility model can be applicable in the biggish continuous cantilever box beam of main spanning diameter.
Although the utility model has been described by way of example and in terms of the preferred embodiments, embodiment does not limit the utility model.Not
It is detached from the spirit and scope of the utility model, any equivalent change or retouch done also belongs to the guarantor of the utility model
Protect range.Therefore the protection scope of the utility model should be based on the content defined in the claims of this application.
