Description

Inclined arch rib supporting and mounting device
Technical Field
The utility model relates to a well formula steel arch bridge construction technical field, in particular to slope arch rib supports and installation device.
Background
The half-through bridge is used for large bridgeSpanThe rib arch bridge of (2) is generally considered when the building height of the bridge is strictly controlled. The arch rib isArch bridgeSkeleton of main arch ring. The arch rib is in the buildingArch waveIn the process, the self-weight, the transverse connection component, the arch wave and the corresponding construction load are borne.
At present, a half-through steel arch bridge is generally fabricated by a construction process of sectional fabrication and field assembly, temporary supports are erected by steel pipes, and lifting equipment is adopted for sectional lifting. The bracket design and buttress design of the inclined arch rib and the conventional arch rib hoisting have the related problems of bracket stability, buttress angle and the like.
Disclosure of Invention
In order to solve the problem of the prior art, the utility model provides a slope arch rib supports and installation device, it can realize arch rib installation and accurate location.
The utility model discloses the technical scheme who adopts as follows:
the utility model provides an incline arch rib and support and installation device, includes the bored concrete pile of concrete strip foundation below, bored concrete pile top be connected with steel pipe support, steel pipe support's top connect the two-way slope buttress through horizontal distribution beam, two-way slope buttress top installation arch rib, the two-way slope buttress's on the horizontal distribution beam both sides be provided with work platform.
An oblique support is arranged between the arch rib and the working platform.
And channel steel cross braces are arranged between the steel pipe brackets.
And a pedestrian ladder is arranged on one side of the steel pipe support.
The utility model provides a beneficial effect that technical scheme brought is:
adopt the utility model discloses a support installation device utilizes the bearing capacity of bored concrete pile, through the platform of steel pipe support as slope arch rib installation, the key technology lies in the preparation and the installation of two-way slope buttress. The technology can solve the problem of accurate installation of various arch ribs in an extending way.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a front view of the inclined arch rib supporting and mounting device of the present invention;
fig. 2 is a left side view of the structure of the oblique arch rib supporting and mounting device of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Example one
As shown in the attached drawing 1, the inclined arch rib supporting and mounting device comprises a cast-in-place pile 1 below a concrete strip foundation 2, a steel pipe support 4 is connected above the cast-in-place pile 1, the top end of the steel pipe support 4 is connected with a bidirectional inclined buttress 6 through a transverse distribution beam 5, an arch rib 10 is mounted at the top of the bidirectional inclined buttress 6, and working platforms 7 are arranged on two sides of the bidirectional inclined buttress 6 on the transverse distribution beam 5.
An oblique support 8 is arranged between the arch rib 10 and the working platform 7.
And channel steel cross braces 3 are arranged between the steel pipe brackets 4.
A pedestrian ladder 9 is arranged on one side of the steel pipe bracket 4.
The method comprises the steps of firstly, calculating the total load according to the weight of an arch rib segment to determine the pile length of a cast-in-place pile 1, facilitating steel pipe support installation for enhancing the integrity and stability of a foundation, pouring a concrete strip foundation 2, installing a steel pipe support 4 according to the height of an arch rib splicing port, and welding a pedestrian ladder 9 on the side face of one steel pipe during steel pipe support installation to facilitate the upper and lower supports of a constructor. Because the steel pipe support is high, adopt channel-section steel bridging 3 to connect between every group support, strengthen the overall stability of support body. And double-spliced 36b I-shaped steel 5 is arranged on the top surface of the steel pipe and serves as a distribution beam and a foundation of a temporary buttress and a construction operation platform. And manufacturing a bidirectional inclined buttress 6 matched with the bottom surface of the arch rib according to the three-dimensional structure of the arch rib, and installing the bidirectional inclined buttress on the transverse distribution beam according to a theoretical position, so that the installation precision of the arch rib is ensured, and the horizontal thrust during installation of the arch rib is eliminated. Meanwhile, a temporary operating platform 7 is erected on the distribution beam by adopting square timber to provide safety guarantee for installation, measurement and positioning. After the arch rib 10 is installed, the inclined support 8 is arranged at the joint position, so that the joint is prevented from displacing before welding.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
