Accompanying drawing explanation
Fig. 1 is the scheme of installation of the tower beam consolidation mechanism of one embodiment of the present of invention；
Fig. 2 is the top view of the tower beam consolidation mechanism of one embodiment of the present of invention.
Detailed description of the invention
The tower beam consolidation mechanism of the present invention is for consolidating Sarasota and girder in cable-stayed bridge, and this mechanism includes
Cushion block and fastening bolt.Cushion block is arranged between Sarasota and girder, for filling between Sarasota and girder
Gap, fastening bolt then sequentially passes through Sarasota, cushion block and girder, and can be to Sarasota, cushion block and girder
Apply pretightning force, thus the formation consolidation between Sarasota and girder constructs, and constrains all directions freely
Degree.
When installing the consolidation mechanism of the present invention, only cushion block need to be placed between Sarasota and girder, install
Fastening bolt also makes fastening bolt stretch-draw pretension；During dismounting, only need to loosen fastening bolt and remove box pad
Block.
The cushion block of the present invention can be used aloned, it is also possible to multiple cushion blocks are stacked to be used, each cushion block
Arrange in pairs or groups at least one fastening bolt.
The fastening bolt of described mechanism can be any workpiece that can apply pretightning force, such as bolt and spiral shell
Female combination.When using bolt, preferably use high-strength bolt.The specification of bolt, number and pre-
The parameters such as clamp force are the most adjustable, are adapted to different size of temporary consolidation force request.
Described cushion block is the filling workpiece of rigidity, and it is formed and size is the most unrestricted, but
It is that preferably there is given shape, so that can be fitted to each other when multiple cushion block is superposed, such as
There is rectangular shape or be similar to the shape of cuboid.Each cushion block shape or size can be identical,
Can also be different, to adapt to gap between different tower beam construction, shape etc..
This cushion block can be i.e. solid, it is also possible to is hollow, but the most hollow, i.e. case
Shape.Meanwhile, in order to pass for fastening bolt, this cushion block has at least one perforation, and this perforation is the most permissible
It is smooth hole, it is also possible to be screw.
The material of cushion block is typically steel, and it can make in factory process, exists at bridge location in-site installation
Between Sarasota and girder.
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with concrete real
Execute example, and referring to the drawings, the present invention is described in further detail.
Fig. 1 is the scheme of installation of the tower beam consolidation mechanism of one embodiment of the present of invention.Such as Fig. 1 institute
Showing, the tower beam consolidation mechanism of this embodiment is installed in single column formula cable-stayed bridge.Construction at cable-stayed bridge
Cheng Zhong, by first building Sarasota, then installs girder, and girder extends from the two of Sarasota lateral span centres and
Closing up eventually, in the installation process of girder, the tower beam consolidation mechanism that can use the present invention temporarily will not
The girder completing to close up is fixed with Sarasota.This tower beam consolidation mechanism is arranged at the friendship of girder and Sarasota
Meet place, generally install with the in-plane of girder.
For the single column formula cable-stayed bridge of this embodiment, Sarasota passes the medium position of girder at vertical direction,
Therefore, the peripheral regions at Sarasota Yu the junction of girder all can arrange the tower beam consolidation mechanism of the present invention.
It is the schematic diagram in the vertical section in the longitudinal extension direction (direction of traffic) at girder due to Fig. 1, therefore
Illustrate only the tower beam consolidation mechanism of both sides across girder direction (shipping agency direction).
Fig. 2 is the top view of the tower beam consolidation mechanism of above-described embodiment, this figure illustrate only Sarasota with
The tower beam consolidation mechanism that the side of the junction of girder is installed.As in figure 2 it is shown, this tower beam consolidation machine
Structure includes box-shaped cushion block and high-strength bolt, and box-shaped cushion block is respectively aforementioned pad with the combination of high-strength bolt
Block and the detailed description of the invention of fastening bolt.
Described box-shaped cushion block is the hollow cuboid component using Steel material to make, and its size can be according to handing over
The size in space, the place of connecing and specifically adjust, and have through multiple perforation in two relative sides,
Penetrating for high-strength bolt.
Additionally, in order to make the combination between cushion block and Sarasota, girder more tight, the tower beam of the present invention
Consolidation mechanism can also include adjusting backing plate, and this adjustment backing plate is arranged between cushion block and Sarasota, or
Between cushion block and girder, for making up the gap between cushion block and Sarasota, girder.This backing plate generally may be used
Being plate shape Steel material, and also have the perforation can passed through for fastening bolt.The thickness of backing plate can not
With, by arranging different adjusting pad plate thickness to adapt to the actual gap between tower beam.
In this embodiment, the size of box-shaped cushion block is 1.6m × 1.3m × 0.6m, adjusts the chi of backing plate
Very little for 1.7m × 1.3m × 0.06m, each box-shaped cushion block and adjust and have 70 equably on backing plate and open
Hole, the model of the high-strength bolt used can be M30-10.9S.
When mounted, first wear at the interstitial site between Sarasota and girder from the hollow space of Sarasota
Enter each high-strength bolt, make high-strength bolt sequentially pass through adjustment backing plate, box cushion block, adjust backing plate and
Girder, arrives the middle vacancy of girder, then at the other end stretch-draw high-strength bolt of high-strength bolt, and overlaps
Enter nut, tighten, finally remove stretching force, make the high-strength bolt of tower beam consolidation mechanism be pressed on girder
With on Sarasota, thus girder, Sarasota are firmly consolidated.
When the interstitial site of the junction between Sarasota and girder has been respectively mounted the tower beam of the present invention admittedly
After knot mechanism, tower beam consolidation mechanism installs.Afterwards, the cantilever of cable-stayed bridge main-beam or outstanding can be carried out
Spelling is installed, and after closing up to full-bridge, can remove tower beam temporary fixed construction.
From above-described embodiment it can be seen that consolidating of being applicable between the Sarasota of cable-stayed bridge and girder of the present invention
Knot, particularly consolidates Sarasota and girder in construction or maintenance process provisionally, such as, is using cantilever
Pour or during erection method construction cable-stayed bridge main-beam.
But, it should also be appreciated that the present invention be readily adaptable for use in engineering construction other building elements it
Between need consolidation field.Install due to the present invention and remove the most more convenient, being therefore more suitable for needing
Want the occasion of temporary consolidation.
Particular embodiments described above, is carried out the purpose of the present invention, technical scheme and beneficial effect
Further describe it should be understood that the foregoing is only the specific embodiment of the present invention,
Be not limited to the present invention, all within the spirit and principles in the present invention, any amendment of being made,
Equivalent, improvement etc., should be included within the scope of the present invention.
