Description

Technical Field

[0001] This utility model belongs to the field of steel pipe arch bridge construction technology, specifically relating to a steel pipe arch rib installation positioning and adjustment device. Background Technology

[0002] The arch rib is the skeleton of the main arch ring of an arch bridge. Steel pipe arch ribs are widely used in steel-concrete composite arch bridges. A steel pipe arch rib is composed of multiple segments spliced ​​together. During installation, construction workers connect these segments sequentially. An arched temporary support is set up below the steel pipe arch rib to provide support for the segments. The segments are hoisted and moved above the support. The arch rib moves along the outside of the support, making it difficult to effectively clamp, position, and adjust the segments from the outside of the support. This makes it easy for workers to cause the arch rib to shift position when manually splicing the segments, affecting subsequent connection and fixation, and impacting work efficiency.

[0020] In this embodiment: the support assembly 1 is used to connect the material support adjustment assembly 2 and the fastening assembly 3. The support assembly 1 consists of a support arch 11, a base 12 and a connecting plate 13. There are two bases 12, which are located at the two ends of the support arch 11 respectively. The rear end of the support arch 11 is fixedly connected to the top of the rear base 12. The connecting plate 13 is fixedly connected to the top of the front base 12. The vertical section of the connecting plate 13 is fixedly connected to the front end of the support arch 11. The support arch 11, the base 12 and the connecting plate 13 are stably combined, and the support arch 11 is stably connected between the two bases 12 through the connecting plate 13.

[0021] The material support adjustment assembly 2 is located inside the support arch 11. The front end of the support arch 11 is an open structure, located inside the connecting plate 13, to facilitate the connection of the material support adjustment assembly 2 to the inside of the support arch 11. The material support adjustment assembly 2 consists of a crossbar 21, a connecting rod 22, and a stop block 23. There are two connecting rods 22 and two stop blocks 23. The two connecting rods 22 are symmetrically fixed to both ends of the crossbar 21. The connecting rods 22 can enter the corresponding guide groove on the side of the support arch 11 through the open area at the front end of the support arch 11, so that the two connecting rods 22 are stably inserted into the corresponding side of the support arch 11, positioning the crossbar 21 inside the support arch 11. The connecting rods 22 can move along the groove inside the corresponding side of the support arch 11. The wall moves, so that the crossbar 21 is stably slidably connected to the inner side of the supporting arch 11 through two connecting rods 22, so as to adjust the position of the crossbar 21 on the inner side of the supporting arch 11. The stop block 23 is slidably connected to the outer side of the crossbar 21. The bottom of the stop block 23 is screwed with a fixing rod 24. The top of the fixing rod 24 abuts against the surface of the crossbar 21. The stop block 23 can move along the surface of the crossbar 21 on the outer side. By operating the fixing rod 24, the stop block 23 can be fixed on the crossbar 21, so as to facilitate the position adjustment and fixing of the stop block 23.

[0022] Each material support adjustment assembly 2 is provided with a fastening assembly 3 below it. The fastening assembly 3 consists of a connecting seat 31 and a side plate 32.

By operating the fastening rod 33, the side plate 32 can be tightly fixed in the inner side of the support arch 11, thereby fixing the material support adjustment assembly 2 as a whole in the designated position inside the support arch 11, so as to facilitate the position fixing operation of the material support adjustment assembly 2 as a whole inside the support arch 11. The connecting seat 31 is provided with a through groove 311 corresponding to the fixing rod 24. The fixing rod 24 is located inside the through groove 311, which can ensure that the fixing rod 24 can rotate smoothly.

[0023] The support assembly 1 can connect multiple material support adjustment assemblies 2 and fastening assemblies 3 according to the number of steel pipe arch rib segments. These three components work together as a bracket to provide support for the steel pipe arch rib segments. The crossbar 21 moves along the arc edge of the support arch frame 11 inside the support arch frame 11 to adjust its position. The position of the crossbar 21 is fixed by screwing the side plate 32 and connecting seat 31 to the bottom of the support arch frame 11, facilitating the adjustment and fixation of the positions of adjacent crossbars 21. The crossbar 21 supports the arch rib segment from below. Two stops 23 move outside the crossbar 21, and after being adjusted to a designated position, their positions are fixed by the fixing rod 24, facilitating the adjustment and fixation of the corresponding stops 23. The stop block 23 can move closer to the arch rib segment by moving outside the crossbar 21, so that after the stop block 23 is fixed, it can clamp the arch rib segment from the outside. This can effectively perform the clamping and fixing of the arch rib segment above the supporting arch frame 11. The operation is simple and can effectively perform the clamping, positioning and adjustment of the steel pipe arch rib segment outside the supporting arch frame 11. This avoids the positional displacement of the steel pipe arch rib when the construction personnel manually splice each segment, improves the stability of the subsequent connection and fixing of the steel pipe arch rib, and improves the work efficiency.
