Abstract

The utility model provides an assembled steel pipe support node structure installs a staple bolt in the steel-pipe pile and the junctor of tie steel pipe and bracing, and the staple bolt includes two semicircular hooping plates, welds a connecting plate respectively along the staple bolt axial in the middle of two hooping plates's the outer wall, the centre of two connecting plates respectively with tie steel pipe tip welding, the upper end and the lower extreme of connecting plate and bracing tip pass through high strength bolt and connect. The utility model discloses node department only needs bolted connection when the support is set up, need not welding operation, has improved assembly speed and quality, can not produce the damage to the component when the support is demolishd, the material later stage recycling of being convenient for.

Description

Assembled steel pipe support node structure
Technical Field
The utility model relates to a used steel-pipe pile supporting structure of bridge construction, the structure of concretely relates to steel-pipe pile support node.
Background
The upper structure of the cast-in-place beam of the bridge is usually constructed by adopting a support, and the cast-in-place beam support cannot adopt a full-space support but adopts a long-span steel pipe support structure in mountain and valley areas due to terrain and geological reasons at the bridge position. When the steel pipe support is erected, adjacent steel pipe piles are connected through cross connections and inclined struts, so that the stability of the support structure is guaranteed, and the joints of the cross connections and the inclined struts and the steel pipe piles are nodes. The traditional steel pipe bracket nodes are mostly connected by welding, the on-site welding workload is large, and the construction period is prolonged; meanwhile, as the welding area is large, large residual stress is easy to generate, and the stress performance of the joint and the overall quality of the support can be influenced. The support needs to be cut when being detached, damages are caused to the steel pipe pile, and material turnover is affected.
Disclosure of Invention
An object of the utility model is to provide an assembled steel pipe support node structure, the support is set up the scene and need not weld, need not cut during the dismantlement, improves construction speed and material turnover rate.
The technical scheme of the utility model as follows:
the utility model provides an assembled steel pipe support node structure, steel pipe support includes many steel-pipe piles, connects its characterized in that through parallel connection steel pipe and bracing between adjacent steel-pipe pile: install a staple bolt at the connected node department of steel-pipe pile and parallel connection steel pipe and bracing, the staple bolt includes two semicircular hoop boards, and two hoop boards pass through staple bolt bolted connection to be fixed on the steel-pipe pile, weld a connecting plate respectively along the staple bolt axial in the middle of the outer wall of two hoop boards, and the centre of two connecting plates welds with a parallel connection steel pipe tip respectively, and the upper end and the lower extreme of connecting plate are equipped with the screw respectively, the both ends of bracing also are equipped with the screw, and the upper end and the lower extreme of connecting plate pass through the screw with high strength bolt connection with the bracing tip.
The utility model discloses the node component can be in the processing welding completion of mill, and the field assembly only needs bolted connection, need not welding operation, and the construction is simple and convenient, has improved assembly speed and quality greatly, can not produce the damage to the component when the support is demolishd, and the material later stage of being convenient for recycles, and economic benefits is obvious.

Detailed Description
As shown in fig. 1, fig. 2, fig. 3, fig. 4, the utility model discloses install a staple bolt 4 at steel-pipe pile 1 and tie up steel pipe 2 and bracing 3's junctor node, staple bolt 4 includes two semicircular hooping plates 41, and two hooping plates 41 pass through staple bolt 42 and connect to be fixed on steel-pipe pile 1, welds a connecting plate 5 respectively along the staple bolt axial in the middle of two hooping plates 41's the outer wall, and the centre of two connecting plates 5 welds with tie up steel pipe 2 tip respectively, and the upper end and the lower extreme of connecting plate 5 are equipped with screw 6 respectively, the both ends of bracing 3 also are equipped with the screw, and the upper end and the lower extreme of connecting plate 5 pass through the screw with bracing 3 tip and are connected with high strength bolt 7.
The utility model discloses during the specific implementation, staple bolt 4 and parallel steel pipe 2 and bracing 3 all process in the workshop in advance, confirm steel pipe support node position according to bridge upper portion size and load, and the size of parallel steel pipe and bracing is confirmed according to steel pipe support's steel pipe stake interval. Notches are formed in the two end portions of the parallel steel pipe along the diameter, and the connecting plates 5 of the two hoop plates are inserted into the notches in the two ends of the parallel steel pipe 2 and are welded in advance.
When in field installation, two hoop plates of one hoop 4 are buckled at the node of the steel pipe pile 1 and fastened by hoop bolts, and the steel pipe bracket is connected with the steel pipe 2 in parallel, thus completing installation; and (3) connecting the inclined strut 3 with the connecting plate 5 on the hoop 4 through a screw hole by using a high-strength bolt 7, and finishing the installation of the inclined strut of the steel pipe bracket. In order to adjust the error of the inclined strut size caused by insufficient blanking precision, the screw holes 6 at the end parts of the connecting plate and the inclined strut are both arranged into strip-shaped slotted holes.
