The utility model discloses a kind of large-span steel and support multidirectional connector, it comprises steel cylinder, joint and rod member, described joint is arc, the middle part of described joint is welded with rod member, described joint both sides have at least three radially-arranged first bolts hole, the surrounding of described steel cylinder is provided with at least one group of second bolt hole corresponding with the first bolt hole, and the surrounding of described steel cylinder is connected by bolt is at least vertical with joint, and described steel cylinder is enclosed within steel post.The utility model can realize multi-direction, multi-angle and regulate Distance geometry height between rod member, the size of specification connector, make to exchange between all parts and general, urban district large-span deep foundation pit and irregular deep foundation ditch can be applied to, thus raising technology, make foundation pit support construction more simple, quick.

Description

Large-span steel supports multidirectional connector
Technical field
The utility model relates to Geotechnical Engineering field, refers to that a kind of large-span steel supports multidirectional connector particularly.
Background technology
In pattern foundation pit supporting structure, bracing members because of its speed of application fast, easy to use, and excellent anti-seismic performance, has obtained general application.But steel support structure needs Shi Hanzhang cannot be used for large area large span mostly, and single direction also makes design can not reach the most effective form of structure in irregular foundation pit support.Although and traditional steel concrete supporting can have the form of structure of science, construction speed can not accomplish with digging with propping up slowly, and can not reuse, not only wasting material but also in dismounting, extreme difficulties being brought to engineering.The connected mode of traditional steel support structure has: riveted joint, welding, flange etc., because the steel support structure that adopts at present is mainly using single shaped steel or steel pipe as brace summer, and can not reach between every root type steel or steel pipe and connect at any angle, therefore, often cannot use as combining structure, formed like this the force limited that can bear of bracing members, thus limit the scope of application, particularly for the foundation ditch that span is larger
Summary of the invention
The purpose of this utility model will provide a kind of large-span steel to support multidirectional connector exactly, multi-direction, multi-angle can be realized according to the needs of design at work progress and regulate Distance geometry height between rod member, the size of specification connector, make to exchange between all parts and general, ensure construction quality, operation is easier to for conventional steel bar concrete supporting, time saving and energy saving, improve efficiency of construction and can reuse; For the stressed more science of existing bracing members, be applicable to irregular large-area pattern foundation pit supporting structure.
For realizing this object, a kind of large-span steel designed by the utility model supports multidirectional connector, it is characterized in that: comprise steel cylinder, joint and rod member, described joint is arc, the middle part of described joint is welded with rod member, described joint both sides have at least three radially-arranged first bolts hole, the surrounding of described steel cylinder is provided with at least one group of second bolt hole corresponding with the first bolt hole, the surrounding of described steel cylinder is connected by bolt is at least vertical with joint, and described steel cylinder is enclosed within column.
Further, described first bolt hole and the arrangement of the second bolt hole indentation.
Further, described steel cylinder is identical with the radius of joint.
Further, described rod member is steel cylindrical tube.
Further, described steel cylinder is connected with 2 ~ 8 rod members are vertical.
The beneficial effects of the utility model: use arc-shaped joint by adopting and realize the Distance geometry height multi-direction, multi-angle adjustment rod member through the steel cylinder of column, the size of specification connector, make to exchange between all parts and general, and between steel cylinder and column, concreting realizes the connection of steel cylinder and column.Can be applicable to urban district large-span deep foundation pit and irregular deep foundation ditch, thus improve technology, make foundation pit support construction more simple, quick.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
A kind of large-span steel as Figure 1-4 supports multidirectional connector, comprise steel cylinder 1, joint 2 and rod member 3, described joint 2 is arc, the middle part of described joint 2 is welded with rod member 3, described joint 2 both sides have at least three radially-arranged first bolts hole 4, the surrounding of described steel cylinder 1 is provided with at least one group of second bolt hole 5 corresponding with the first bolt hole 4, and the surrounding of described steel cylinder 1 is connected by bolt is at least vertical with joint 2, and described steel cylinder 1 is enclosed within column 6.In Excavation Process, by the arc-shaped joint 1 of multiple different angles and the connection of the steel cylinder 2 through column, connect with multidirectional, the multi-angle that realize rod member 3, concreting in steel cylinder 2, thus the reliable structure forming concrete filled steel tube.Column can overlap multiple steel cylinder 1 to realize the multilayer supporting of deep foundation ditch, be applied to urban district large-span deep foundation pit and irregular deep foundation ditch, improve technology, make foundation pit support construction more simple, quick.
In such scheme, described first bolt hole 4 and the arrangement of the second bolt hole 5 engrail.According to different supporting type erection bolt, worn outward by interior during erection bolt, make nuts outside, then concreting in steel cylinder 1, removes connector after waiting supporting to be done, backs out the bolt outside steel cylinder 1, take off connector head, reject other parts, complete supporting.
In such scheme, described steel cylinder 1 is identical with the radius of joint 2, and joint 2 and steel cylinder 1 can be fitted tightly.
In such scheme, described rod member is steel cylindrical tube.
In such scheme, described steel cylinder is connected with 2 ~ 8 rod members are vertical, can realize multi-direction, multi-angle and regulate Distance geometry height between rod member.
The above; be only detailed description of the invention of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
