Abstract
The utility model provides a section closure was with rear -mounted strength nature skeleton concrete arch rib festival, including concrete arch rib festival section (1), skeleton bearing plate (4), spacing shoulder pole reinforcing bar (3), the inside of concrete arch rib festival section (1) is along being equipped with uniformly all around of cross -section many reinforcing bars (2), 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, 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), skeleton curb plate (6) vertical welding is equipped with skeleton roof (5) between the upper end of two skeleton curb plate (6) on skeleton bearing plate (4), the higher authority of skeleton roof (5) is equipped with square slotted hole. This skeleton not only has traditional box skeleton texture and bears the weight of dynamic height, the good characteristics of stability, and is convenient for according to preparation of the on -the -spot circumstances and installation.
Description
Technical field
The utility model belongs to technical field of bridge engineering, is specifically related to the closure of a kind of concrete arch rib sections and uses rear-mounted 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 truss-like or case structure.The feature of truss-like skeleton compares saving steel, but easily local buckling occurs when stressed; The feature of case structure is that bearing capacity is high, good stability.Often stiff skeleton during closure is designed to pre-buried type in prefabricated reinforced concrete arch rib assembling construction, the skeleton pre-plugged being about to process is in concrete arch rib sections.The stiff skeleton size of pre-buried type is fixed, and carrys out adjust size, waste time and energy, seriously reduce efficiency of construction when error appears in construction at the scene often through the mode being welded with skeleton or cutting skeleton.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of concrete arch rib sections to join the two sections of a bridge, etc and uses rear-mounted stiff skeleton, and this stiff skeleton bearing capacity is high, good stability, making and installation are simple, is convenient to make according to field condition and install.
To achieve these goals, the utility model provides a kind of concrete arch rib sections to join the two sections of a bridge, etc and uses rear-mounted stiff skeleton, comprise concrete arch rib sections, skeleton bearing plate, spacing shoulder pole reinforcing bar, skeleton top board and skeleton side plate, the inside of concrete arch rib sections is provided with many reinforcing bars equably along the surrounding in 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, the middle part that each skeleton bearing plate deviates from the one side of concrete arch rib sections is equipped with a skeleton side plate, described skeleton side plate is vertically welded on skeleton bearing plate, skeleton top board is provided with between the upper end of two skeleton side plates, square slotted eye is provided with above skeleton top board.
The two ends up and down of two described skeleton bearing plates are fixedly installed a spacing shoulder pole reinforcing bar respectively, and the two ends of described spacing shoulder pole reinforcing bar are fixedly connected with the reinforcing bar of nearest with spacing shoulder pole reinforcing bar on concrete arch rib sections.
In this skeleton, two skeleton side plates and a skeleton top board and skeleton bearing plate constitute one in inverted U-shaped case structure, and this box skeleton can be pre-processed, behind scene, be then fixed in the termination of concrete arch rib sections again.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.

Fig. 3 is top view of the present utility model.
In figure: 1, concrete arch rib sections, 2, reinforcing bar, 3, spacing shoulder pole reinforcing bar, 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, rear-mounted stiff skeleton is used in a kind of concrete arch rib sections closure, comprise concrete arch rib sections 1, skeleton bearing plate 4, spacing shoulder pole reinforcing bar 3, skeleton top board 5 and skeleton side plate 6, the inside of concrete arch rib sections 1 is provided with many reinforcing bars 2 equably along the surrounding in 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, the middle part that each skeleton bearing plate 4 deviates from the one side of concrete arch rib sections 1 is equipped with a skeleton side plate 6, described skeleton side plate 6 is vertically welded on skeleton bearing plate 4, skeleton top board 5 is provided with between the upper end of two skeleton side plates 6, square slotted eye is provided with above skeleton top board 5, concrete perfusion can be facilitated like this.
The two ends up and down of two described skeleton bearing plates 4 are fixedly installed a spacing shoulder pole reinforcing bar 3 respectively, and the two ends of described spacing shoulder pole reinforcing bar 3 are fixedly connected with the reinforcing bar 2 of nearest with spacing shoulder pole reinforcing bar 3 on concrete arch rib sections 1.
Two skeleton side plates 6 and a skeleton top board 5 constitute one in inverted U-shaped case structure with skeleton bearing plate 4, and this box skeleton can be pre-processed, behind scene, be then fixed in the termination of concrete arch rib sections 1 again.Arrange a spacing shoulder pole reinforcing bar 3 of horizontal direction respectively particular by the upper and lower side at skeleton bearing plate 4, spacing shoulder pole reinforcing bar 3 welds with reinforcing bar 2 nearest on concrete arch rib sections 1 cross section, is fixed by the stiff skeleton of 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.
