Description
Technical field
The utility model belongs to field of bridge construction, and in particular to a kind of construction bracket of continuous beam cantilever 0# blocks.
Background technology
With the fast development of China's infrastructure, continuous beam cantilever pouring construction method is superior because its ripe uniqueness
Property, it is increasingly used for the region of the support cast-in-place constructional difficulties such as cross a river stream, mountain valley, road.Poured in continuous beam cantilever
During construction, basis that 0# blocks are constructed as cantilever pouring, because of its size and quality is larger and its surrounding enviroment is complicated and changeable, easily
Cause safety and quality problems.
When cantilever pouring continuous beam 0# blocks are constructed, construction condition is typically poor, need to be complete in narrow and small high dummy section
Poured into prevention of mass concrete, and construction site geological conditions typically changes greatly.If using conventional construction support, it is necessary to 0# blocks
Neighbouring place is handled on a large scale, could strictly control the sedimentation of 0# blocks.Also, this method is using material is more, constructing accounts for
Ground is larger, and in the environment of geological condition complexity, narrow space, the diagonally disposed construction safety risk of steel pipe is larger, and branch be present
The problem of frame sedimentation is uneven, construction safety hidden danger is larger.
Utility model content
Purpose of utility model：The utility model purpose is in view of the shortcomings of the prior art, there is provided a kind of continuous beam cantilever
The construction bracket of 0# blocks.The utility model, which makes, implements safety simple, easy for construction, has saved construction cost, has improved construction
Quality and efficiency.
Technical scheme：The construction bracket of continuous beam cantilever 0# blocks described in the utility model, bridge pier along its length two
Side is separately installed with two temporary supports, and the bottom of temporary support is fixed on cushion cap；The top of temporary support set one with
The vertical equity bar of bridge pier connection, vertical equity bar are connected with pier shaft built-in fitting；Some height are provided with vertical equity bar
Gradual increased vertical supporting bar from inside to outside；Transverse horizontal bar, the both ends point of transverse horizontal bar are set above vertical supporting bar
It is not fixed on the corresponding vertical supporting bar of two temporary supports of bridge pier homonymy；Longitudinal brace master is set above transverse horizontal bar
It is stupefied, transverse horizontal bar and longitudinal brace master it is stupefied between connected by voussoir.
Further, it is fixed with shelf bracket between the temporary support and vertical equity bar.
Further, the bottom of the temporary support is welded and fixed by pre-embedded steel slab on cushion cap.
Further, the transverse horizontal bar at longitudinal stupefied contact position of brace master using U-bolt with being fixed.
Beneficial effect：（1）The utility model is less using material installation, Neng Gou less demanding to construction site condition
Narrow space carries out crossed construction, has saved cost, has shortened the engineering time, has improved efficiency of construction；
（2）Due to eliminating original primary load bearing steel pipe support, by temporary support, load is transferred to pier cap
On, avoid the support caused by Geological condition difference and settle non-uniform phenomenon, enhance working security；
（3）Because being not provided with rigid temporary support between pier coping portion and 0# block box beams, it is possible to achieve the lotus that bearing is born
It is loaded in the propulsion of cantilever casting construction progress and increases, avoids to greatest extent after beam body is closed up when contacting temporary support because of branch
Seat depression and the problem of produce larger structure second inner force.

Technical solutions of the utility model are described in detail below by accompanying drawing, but the scope of protection of the utility model
It is not limited to the embodiment.
Embodiment 1：A kind of construction bracket of continuous beam cantilever 0# blocks, as shown in figure 1, bridge pier 2 along its length two
Side is separately installed with two temporary supports 3, and the bottom of temporary support 3 is fixed on cushion cap 1；The top of temporary support 3 sets one
The vertical equity bar 5 that root is connected with bridge pier 2, vertical equity bar 5 are connected with pier shaft built-in fitting；Temporary support 3 and vertical equity bar 5
Between be fixed with shelf bracket 4；Some height gradual increased vertical supporting bar from inside to outside is provided with vertical equity bar 5
6；The top of vertical supporting bar 6 sets transverse horizontal bar 7, and the both ends of transverse horizontal bar 7 are separately fixed at 2 homonymy of bridge pier two temporarily
On the corresponding vertical supporting bar 6 of support 3；The top of transverse horizontal bar 7 sets longitudinal brace master stupefied 9, and transverse horizontal bar 7 and longitudinal direction are tiltedly
Connected between bar master stupefied 9 by voussoir 8.
The construction bracket of continuous beam cantilever 0# blocks described in the utility model be by it is lower from the upper vertical equity bar of consolidation in advance 5,
Shelf bracket 4, vertical supporting bar 6, transverse horizontal bar 7 and longitudinal brace master stupefied 9 are then placed, then on longitudinal brace master stupefied 9
The lumps of wood, bed die and Bian Mo are laid, so as to form complete 0# block construction supports and template system.
