Accompanying drawing explanation
Fig. 1 is vertical structure schematic diagram of the present invention;
Fig. 2 is transversary schematic diagram of the present invention.
Detailed description of the invention
Now the present invention is further described with specific embodiment by reference to the accompanying drawings.
With reference to the accompanying drawings the specific embodiment of the present invention is described.
See figures.1.and.2, the supporting shelf bracket of a kind of cantilever bridge No. 0 block, comprises two groups of bracing frames 10.The left and right sides of bridge pier pier shaft 11 is located at by these two groups of bracing frames 10.Often organize bracing frame 10 to comprise and be installed in horizontal girder 12 on bridge pier pier shaft 11 and raker beam 13.The top of this raker beam 13 is connected with horizontal shore 12, and the bottom of this raker beam 13 is connected with strengthens steel plate 22, and the bottom surface of this reinforcement steel plate 22 is connected with crossbeam 17, and the bottom of crossbeam 17 is connected with latch rod, and this latch rod inserts in the preformed hole of bridge pier pier shaft 11.Latch rod is latch rod iron 14, thus strengthens the intensity of latch rod, avoids fracture.The below of latch rod iron 14 is also provided with the supporting steel plate 16 for supporting latch rod iron, this supporting steel plate 16 shape triangular in shape.
With reference to Fig. 1, bracing frame 10 also comprises oblique reinforcement web member 15.One end of this oblique reinforcement web member 15 is connected with the head of horizontal girder 12, and the other end of this oblique reinforcement web member 15 is connected with the middle part of raker beam 13.The setting of oblique reinforcement web member 15, can improve the bearing capacity of raker beam 13 greatly.Oblique reinforcement web member 15 is 90 ° with the angle of raker beam 13, thus raker beam 13 can be made to have larger bearing capacity.
See figures.1.and.2, horizontal girder 12 has complex root, and this complex root horizontal girder 12 be arranged in parallel.Raker beam 13 has complex root, and this complex root raker beam 13 be arranged in parallel.Oblique reinforcement web member 15 has complex root, and the oblique reinforcement web member 15 of this complex root be arranged in parallel.Latch rod iron 14 also has complex root.Described crossbeam 17 is connected on this plurality of latch rod iron 14.The bottom of raker beam 13 welds together with reinforcement steel plate 22.The cross section strengthening steel plate 22 is L-shaped, makes reinforcement steel plate 22 larger with the bonding area of raker beam 13, more firmly.The oblique reinforcement web member 15 of complex root utilizes a connecting rod 18 to connect, thus improves the resistance to overturning of gusseted bracket.
See figures.1.and.2, the horizontal girder 12 of two groups of bracing frames 10 utilizes the pull bar 19 of high strength to connect, and the two ends of this pull bar 19 are provided with screw thread, and the two ends of this pull bar 19 are equipped with nut 20, and this pull bar 19 is through the pull bar preformed hole of bridge pier pier shaft 11.Thus the horizontal girder 12 of these two groups of bracing frames 10 can be made to link together firmly, make this supporting shelf bracket more firm.The two ends of the reinforcement steel seat 17 of two groups of bracing frames 10 are respectively equipped with tie rod hole 21, thus the screwed pull bar in two ends and nut can be utilized to fix this two crossbeams 17, make the supporting shelf bracket of these bridge pier pier shaft 11 both sides form entirety.
It should be noted that: in order to adapt to the use of product of the present invention herein, bridge pier pier shaft 11 above-mentioned needing be reserved with the preformed hole of a plurality of latch rod and a plurality of pull bar preformed hole in advance.Preformed hole adopts and buries pvc pipe or steel pipe underground, buries the readily removable film shutoff removed in pipe two ends underground, prevents concrete from entering in pipe.Bury effective reinforcing bar location underground, prevent positioning.
With reference to Fig. 1, the support system that the present invention only need will can complete in the preformed hole of the latch rod of latch rod insertion bridge pier pier shaft 11 below crossbeam 17, simple to operate.Load on supporting shelf bracket can be reached latch rod iron 14 by raker beam 13 by the present invention, then by latch rod iron 14 power transmission on the bridge pier completed, simply stressed, power transmission is clear and definite.The present invention supports shelf bracket owing to adopting unsettled installation, avoids the special requirement in the basic ring border over the ground of console mode installation bracket in prior art.Present invention, avoiding pre-embedded steel slab or shaped steel in prior art need cut off, clear up weldering spot, rust cleaning, painting rustproof paint, smear the complex operations such as high grade mortar.Weld the impact that warm welding can cause the intensity of pier shaft concrete when avoiding former welding simultaneously.The present invention can process various accessory on ground, in-site installation, and mechanical one-shift is few, reduces amount of high-altitude operation, shortens the high-altitude application time.The present invention is easy for installation, and operation work post is less, reduces cross-operation and interferes with each other, alleviating personnel labor intensity.Mounting technique difficulty of the present invention is little, and common work post does not need extraordinary work, optimizes the configuration of manpower.In sum, the present invention effectively cost-saving, raise the efficiency, safety more secure.
Above are only the specific embodiment of the present invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
