The concrete of inside filling.The steel plate concrete prefabricated board includes that board bottom steel plate, T-steel, board bottom one-way reinforcement, plate top are double
The concrete that oblique reinforcing bar, top are filled into reinforcing bar, plate.When contignation system is constructed, first by steel plate concrete precast beam
It is fixed on bracket bearing, then steel plate concrete prefabricated board is chosen mounted on precast beam on ear, finally in precast beam and in advance
Casting concrete overlapping layers in making sheet.
Invention content
The utility model mesh by being fabricated to the curved plate of certain radius, curved plate be placed on bearing top and its
He is built up temporary support by steel plate together.
The above-mentioned technical purpose of the utility model technical scheme is that：Ramp bridge scaffold curved plate
Bearing, including several horizontal stacked steel plate layers are overlapped, the steel plate layer has top layer, and there are one upwards for the topsheet surface tool
Cambered surface, the cambered surface r, 30 ° of 60 ° of ＜ r ＜ with an angle.
Preferably, the horizontal area of the steel plate layer is in descending arrangement from top to bottom.
Preferably, the horizontal area of the steel plate layer is 1 from top to bottom:3/4:1/2:1/4.
Preferably, freely placing or being fixedly connected between the steel plate layer.
Preferably, the top layer is high-strength abrasion-proof steel.
Preferably, the top layer uses No. 45 steel.
Preferably, the steel plate layer uses 235 steel plate of common Q.
The advantageous effects of the utility model are：
The present apparatus is to be fabricated to the curved plate of certain radius, curved plate is placed on using the relatively high steel of wearability
The top of bearing and other steel plates are built up temporary support together, have adaptation range of grade wide, uniform force, no thrust,
Steel plate can be increased or decreased as needed come the advantages that adjusting height of support.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model；
1- steel plate layers, 11- top layers, 12- cambered surfaces.
Specific implementation mode
Embodiment one, Ramp bridge scaffold curved plate as shown in Figure 1 overlap bearing, including several horizontal stacked steel plate layers
1, steel plate layer 1 has top layer 11, and there are one upward cambered surfaces 12 for 11 surface of top layer tool, and there are one 30 ° of angle r for the tool of cambered surface 12.
The horizontal area of steel plate layer 1 is in descending arrangement from top to bottom, and the horizontal area of steel plate layer 1 is 1 from top to bottom:3/4:1/2:
1/4.It is welded between steel plate layer 1.Top layer 11 is adopted using high-strength abrasion-proof steels material, the steel plate layers 1 in addition to top layer 11 such as No. 45 steel
With common（Q235）Steel plate makes.This device is applied in the construction of cast-in-place binder scaffold, and the bridge location is on vertical curve, by this
Device solves the problems, such as the uneven and resulting bracket stable of the continually changing holder Bearing Seat Force of Beam Elevation.
Embodiment two, Ramp bridge scaffold curved plate as shown in Figure 1 overlap bearing, including several horizontal stacked steel plate layers
1, steel plate layer 1 has top layer 11, and there are one upward cambered surfaces 12 for 11 surface of top layer tool, and there are one 45 ° of angle r for the tool of cambered surface 12.
The horizontal area of steel plate layer 1 is in descending arrangement from top to bottom, and the horizontal area of steel plate layer 1 is 1 from top to bottom:3/4:1/2:
1/4.It is welded between steel plate layer 1.Top layer 11 is adopted using high-strength abrasion-proof steels material, the steel plate layers 1 in addition to top layer 11 such as No. 45 steel
With common（Q235）Steel plate makes.
Embodiment three, Ramp bridge scaffold curved plate as shown in Figure 1 overlap bearing, including several horizontal stacked steel plate layers
1, steel plate layer 1 has top layer 11, and there are one upward cambered surfaces 12 for 11 surface of top layer tool, and there are one 60 ° of angle r for the tool of cambered surface 12.
