Abstract
The invention discloses an integral-structure type rear upper separator of a diamond cradle, which comprises an upper beam and a lower beam arranged between two diamond trusses, wherein two ends of the upper beam are fixed at the upper ends of two diamond truss web members, the lower beam is fixed at the middle lower parts of the two diamond truss web members, two ends of the lower beam respectively extend to the outer sides of the web members, the lower beam is provided with a prepared hole through which a hanging rod can pass, the upper beam is connected with the lower beam through a plurality of inclined channel steel. The rear upper separator has high rigidity, can bear higher load acting force, and has smaller deflection; and a hoisting point acts on the rear upper separator, thus the risk of crushing wing plates is avoided. Relative to the cradle of the first type, the integral-structure rear upper separator reduces the using amount of materials, and simultaneously reduces the self-weight of the cradle and saves the cost.
Description
Technical field
The invention belongs to bridge engineering construction equipment field, be specifically related to the back top rail on a kind of Diamond-Shape Form Traveler.
Background technology
Diamond-Shape Form Traveler is widely used in the segmentation cantilever casting construction of large-span continuous girder bridges and continuous rigid frame bridge, and it mainly partly is made up of load bearing system, walking system, inside and outside modular system, suspension system, five of anchor devices.As shown in Figure 5 and Figure 6, wherein the load bearing system main member is made up of rhombus truss 1, preceding top rail, back top rail 3, preceding lower transverse beam, back lower transverse beam 5, bottom girder 6, outer nose girder 7, suspension rod 8, interior nose girder 9 etc., is provided with section bracing 10 between two rhombus truss 1.
At present, the form of the back top rail of Diamond-Shape Form Traveler mainly contains Two bors d's oeuveres large size shaped steel and directly is erected at rhombus truss top (first kind of form in engineering circle, see Fig. 5 for details) and cancellation back top rail, suspension centre acts directly on (second kind of form sees Fig. 6 for details) two kinds of forms on the top board and wing plate that waters the beam piece.The major defect of first kind of form is in the Hanging Basket reach process, back top rail only is subjected to the load action power (all the other suspension centres are removed) of two suspension centres of outermost end when reach, back top rail stress point span is big (fulcrum is two rhombus main truss sheets), be again cantilever force simultaneously, therefore the back top rail produce amount of deflection and flexural tensile stress all very big.The shortcoming of second kind of form is in the Hanging Basket cantilever process, and it is bigger to act on the wing plate point load of hanging oneself, and case beam wing plate is again a cantilever force simultaneously, thereby is easy to damage wing plate by pressure.
Summary of the invention
The present invention is directed to the deficiency of two kinds of back top rails commonly used of present engineering circle Diamond-Shape Form Traveler, a kind of back top rail that original section bracing forms to two ends expansion extension between the rhombus truss that utilizes is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: top rail after the Diamond-Shape Form Traveler overall structure formula, form by being located at two upper beam and underbeams between the rhombus truss, the two ends of putting the beams in place are fixed on the upper end of two rhombus truss web, underbeam is fixed on the middle and lower part of two rhombus truss web, the two ends of underbeam extend to the outside of web member respectively, but underbeam is provided with the preformed hole of tying up bar, connect by some oblique channel-section steels between upper beam and the underbeam.
Described oblique channel-section steel is the six roots of sensation, and the center is connected between upper beam and the underbeam symmetrically.
Described upper beam is connected by vertical channel-section steel with the underbeam middle part.
Described upper beam is made up of two channel-section steels, and the both sides that two channel-section steels are attached to web member are back-to-back fixed.
Described underbeam is made up of two channel-section steels, and the both sides that two channel-section steels are attached to web member are back-to-back fixed.
Because the back top rail of first kind of form of Diamond-Shape Form Traveler in present engineering circle and the section bracing between the sheet of rhombus purlin are integrated in the present invention, form the system that overall structure is stressed, first kind of form not only saved material in engineering circle relatively at present, section bracing between truss is integrated with the back top rail, by the back top rail with force transmission to the rhombus purlin sheet of Hanging Basket, so just both can make rhombus truss and back top rail form the monolithic force structure, strengthened the overall structure stress-bearing capability of Hanging Basket, reduce the position of suspension centre in addition, helped strengthening the stability against overturning of Hanging Basket; Second kind of form not only reduced the stressed of various suspension centres in engineering circle relatively at present, avoided damaging by pressure the risk of wing plate simultaneously.
In sum, the present invention compares with existing Diamond-Shape Form Traveler design, and its advantage is:
1, back top rail rigidity is big, can bear bigger load action power, and amount of deflection is less;
2, suspension centre acts on the top rail of back, the risk of having avoided damaging by pressure wing plate.
3, after the overall structure formula top rail with respect to the Hanging Basket of first kind of form, the consumption of the material of minimizing, cost has been saved in the deadweight that has simultaneously also alleviated Hanging Basket.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further details, these embodiment only are used for illustrating the present invention, do not limit the scope of the invention.
As shown in Figures 1 to 4, the load bearing system main member of Diamond-Shape Form Traveler is made up of rhombus truss 1, preceding top rail 2, back top rail 3, preceding lower transverse beam 4, back lower transverse beam 5, bottom girder 6, outer nose girder 7, suspension rod 8, interior nose girder 9 etc.Top rail after the Diamond-Shape Form Traveler overall structure formula of the present invention, form by being located at two upper beam 12 and underbeams 13 between the rhombus truss 1, the two ends of upper beam 12 are fixed on the upper end of two rhombus truss web 11, described upper beam 12 is made up of two channel-section steels, and the both sides that two channel-section steels are attached to web member 11 are back-to-back fixed.Described underbeam 13 is fixed on the middle and lower part of two rhombus truss web 11, and the two ends of underbeam 13 extend to the outside of web member respectively, and about 50 centimetres of case beam wing plate edge is stretched out at the underbeam two ends.Underbeam 13 is made up of two channel-section steels, and the both sides that two channel-section steels are attached to web member are back-to-back fixed, and above-mentioned channel-section steel is locking solid with rhombus truss contact position with iron.Connect by some oblique channel-section steels 14 between upper beam 12 and the underbeam 13, connected mode is oblique plug and socket connection, and described oblique channel-section steel 14 is the six roots of sensation, and the center is connected between upper beam and the underbeam symmetrically.Described upper beam 12 is connected by two vertical channel-section steels 15 with underbeam 13 middle parts.In addition, in the underbeam 13 that constitutes by channel beam, reserve the hole of respective numbers, as the preformed hole of tying up bar.
