Abstract
The utility model provides a putting forth one's strength nature of concrete arch rib festival section closure construction skeleton, including concrete arch rib festival section (1), skeleton bearing plate (4), skeleton roof (5) and skeleton curb plate (6), the inside of concrete arch rib festival section (1) is being equipped with all around of edge many reinforcing bars (2) along the cross -section outside, two skeleton bearing plate (4) are vertical to parallel ground, it is regional at the middle part of concrete arch rib festival section (1) terminal surface to control the closely connected setting in ground of looks interval, up end that every skeleton bearing plate (4) are close to concrete arch rib festival section (1) and terminal surface down respectively are provided with skeleton dowel (3) that are L shape of an embedding in concrete arch rib festival section (1), the middle part that every skeleton bearing plate (4) deviate from the one side of concrete arch rib festival section (1) all is equipped with one skeleton curb plate (6) perpendicularily, be equipped with skeleton roof (5) between the upper end of two skeleton curb plate (6). This strength nature skeleton bears the weight of the dynamic height, stability is good.
Description
Technical field
The utility model belongs to technical field of bridge engineering, is specifically related to a kind of concrete arch rib sections closing construction stiff skeleton.
Background technology
Arch Bridge Construction many employings prefabrication and assembly construction construction method.Arch rib is prefabricated in advance in prefabricated component field, and the scene of being transported to is assembled.Rib-lifting section needs when being interconnected closure by stiff skeleton, two segment to be carried out temporary locking in advance, finally builds the concrete between sections.Stiff skeleton bears compressive stress when constructing, and ensures that the power transmission of arch rib is continuous, makes rib-lifting section become closed arch ring temporarily, complete bridge system transform.
Stiff skeleton between rib-lifting section is generally designed to lattice steel truss, is welded into space truss as adopted channel-section steel, i iron etc.The advantage of lattice steel truss compares saving steel, and be easy to vibrate when concreting, therefore welcomes by unit in charge of construction very much.The facilities such as the interim skeleton of site operation are often by unit in charge of construction's designed, designed, unit in charge of construction's design analysis technical capability own is on the weak side, but this lattice steel truss requires high to designing and calculating, once it is inadequate to design stressed safety stock, skeleton is easy to produce local buckling when temporary locking is stressed, the lighter affects the linear quality of arch ring, and serious also engineering accident can occur.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of concrete arch rib sections closing construction stiff skeleton, and this stiff skeleton bearing capacity is high, good stability, safety are high, and can meet easily the vibrating property of concreting.
To achieve these goals, the utility model provides a kind of concrete arch rib sections closing construction stiff skeleton, comprise concrete arch rib sections, skeleton bearing plate, skeleton top board and skeleton side plate, the inside of concrete arch rib sections is provided with many reinforcing bars along the surrounding of outer, cross section, two skeleton bearing plates vertically parallel ground, the left and right closely connected central region being arranged on concrete arch rib segment at intervals, each skeleton bearing plate is respectively provided with a L-shaped skeleton dowel be embedded in concrete arch rib sections near the upper surface of concrete arch rib sections and lower surface, the middle part that each skeleton bearing plate deviates from the one side of concrete arch rib sections is all vertically provided with a skeleton side plate, skeleton top board is provided with between the upper end of two skeleton side plates.
For convenience of concrete perfusion, above skeleton top board, be provided with square slotted eye.
For improving bearing capacity intensity, described skeleton dowel is arranged relative to concrete arch rib segment level.
In this skeleton, two skeleton side plates and a skeleton top board and skeleton bearing plate constitute one in inverted U-shaped case structure, this skeleton not only has that traditional box cage construction bearing capacity is high, the feature of good stability, and is convenient to make according to field condition and install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side of the present utility model elevation;
Fig. 3 is top view of the present utility model.
In figure: 1, concrete arch rib sections, 2, reinforcing bar, 3, skeleton dowel, 4, skeleton bearing plate, 5, skeleton top board, 6. skeleton side plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of concrete arch rib sections closing construction stiff skeleton, comprise concrete arch rib sections 1, skeleton bearing plate 4, skeleton top board 5 and skeleton side plate 6, the inside of concrete arch rib sections 1 is provided with many reinforcing bars 2 along the surrounding of outer, cross section, two skeleton bearing plates 4 vertically parallel ground, the left and right closely connected central region being arranged on concrete arch rib sections 1 end face at intervals, each skeleton bearing plate 4 is respectively provided with a L-shaped skeleton dowel 3 be embedded in concrete arch rib sections 1 near the upper surface of concrete arch rib sections 1 and lower surface, the middle part that each skeleton bearing plate 4 deviates from the one side of concrete arch rib sections 1 is all vertically provided with a skeleton side plate 6, skeleton top board 5 is provided with between the upper end of two skeleton side plates 6.
For convenience of concrete perfusion, above skeleton top board 5, be provided with square slotted eye.
Described skeleton dowel 3 is flatly arranged relative to concrete arch rib sections 1.
By skeleton dowel 3 pre-plugged in concrete arch rib sections 1, and itself and skeleton bearing plate 4 are fixed together, the tensile strength of this skeleton entirety can be improved, the bearing capacity of case structure skeleton can be strengthened.Skeleton top board 5 is provided with between the upper end of two skeleton side plates 6.Two skeleton side plates 6 and skeleton top board 5 constitute one in inverted U-shaped case structure with skeleton bearing plate 4, and this skeleton not only has that traditional box cage construction bearing capacity is high, the feature of good stability, and is convenient to make according to field condition and install.
