A kind of crossbeam embedded type clamp
Technical field
The utility model relates to a kind of light section steel structure link technique field, is specifically related to a kind of crossbeam embedded type clamp.
Background technology
Light section steel structure is in building of today, few with its material usage, energy-conserving and environment-protective, and anti-seismic performance is good, lightweight, and the advantages such as convenient construction are progressively used widely.In the use of steel work, be that section combination some length is shorter, small volume is stitched together and forms a supporting frame with steel structure that volume is larger, the supporting frame with steel structure larger with this volume supports other structures.
In light section steel structure, generally adopt section bar thin-walled, opening or that remain silent, because section bar wall thickness is thinner, do not allow welding, so general, adopt and be threaded or rivet.Adopt these two kinds of connected modes all can have destruction to a certain degree to section bar, and this destruction generally is the breach of through hole or wedge angle, so the mechanical property of junction section bar significantly reduces in steel work, become the dangerous spot of whole steel work, and, because the Surface of profile topping of junction is destroyed, so the section bar of junction is easily by corrosion, so after each section bar connects, need to eliminate rust to the section bar of junction, brushing maintenance, then, after installing, every one-period, also need junction to safeguard, make follow-up construction complicated.
So, need at present a kind of section bar of can avoiding damaging badly, the light section steel structure jointing clip being easy for installation and removal.
Utility model content
The purpose of this utility model is: for existing light section steel structure connector above shortcomings, provide a kind of crossbeam embedded type clamp.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of crossbeam embedded type clamp, comprise at least two clip bodies and dismountable connecting portion being arranged between described clip body, on described clip body, be provided with the holding tank matching with crossbeam, described clip body comprises the first clip and the second clip arranging in opposite directions, described the first clip and described dismountable connection of the second clip, on described the first clip, be provided with the first holding tank, on described the second clip, be provided with the second holding tank, described the first holding tank and described the second holding tank form described holding tank.When mounted, clip body is arranged on different crossbeams, and then by connecting portion jointing clip body, realize the connection between crossbeam, because clip body is to be clamped on crossbeam by holding tank, when installation and removal, can not damage crossbeam, and owing to passing through the dismountable connection of connecting portion between clip body, after clip body is removed, clip body can be separated and takes in connecting portion, facilitated taking in and carrying of clip.
As preferred version of the present utility model, described the first clip and described the second clip are bolted, and the degree of depth of described holding tank is less than the thickness of described crossbeam.By controlling the degree of tightening of bolt, control the degree that clip body clamps crossbeam.
As preferred version of the present utility model, the bottom of described the first holding tank and the second holding tank is arranged at intervals with some projections on corresponding described the first clip and the second clip respectively.After clip body is clamped on crossbeam, by further tighting a bolt, due to the projection that arranges on clip body, projection withstands on crossbeam, make the distortion of crossbeam generating portion, each projection is absorbed in each self-corresponding depression, when avoiding clip body under shock conditions or being subject to along axial force in crossbeam direction, is shifted.
Further, corresponding with the described projection depression that is provided with on described crossbeam.After clip body is clamped on crossbeam, in the depression on the protruding stemple on clip body, when avoiding clip body under shock conditions or being subject to along axial force in crossbeam direction, be shifted.
As another preferred version of the present utility model, on described crossbeam, on the face corresponding with described holding tank two bottom surfaces, be arranged at intervals with some projections.After clip body is clamped on crossbeam, by further tighting a bolt, due to the projection that arranges on crossbeam, projection withstands on clip body, make the distortion of clip body generating portion, each projection is absorbed in each self-corresponding depression, when avoiding clip body under shock conditions or being subject to along axial force in crossbeam direction, is shifted.
Further, on holding tank two bottom surfaces on described clip body, be arranged at intervals with the depression matching with projection on described crossbeam.After clip body is clamped on crossbeam, projection on crossbeam embeds in the depression on clip body, when avoiding clip body under shock conditions or being subject to along axial force in crossbeam direction, is shifted.
As another preferred version of the present utility model, described the first clip and described the second clip are arranged symmetrically with along mounting plane.The first clip and the second clip are set to symmetrical structure, facilitate the processing and manufacturing of clip body.
As preferred version of the present utility model, described connecting portion two ends become tabular.Connecting portion two ends are set to tabular, after some clip bodies are connected as one by some connecting portions, can become high-intensity girder truss by rapid-assembling.
As preferred version of the present utility model, described connecting portion is shoulder pole shape.Connecting portion is set to shoulder pole shape, after some clip bodies are connected as one by some connecting portions, because shoulder pole shape is slight curving structure, when crossbeam is impacted, connecting portion can produce certain distortion and impact-absorbing, avoid impacting crossbeam when excessive and the device that is arranged on crossbeam damaged.
As preferred version of the present utility model, the projection of adjacent two described connecting portions in the plane of vertical and described crossbeam is symmetrical along installed surface.Guarantee adjacent two connecting portion stress balances.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1,, when avoiding section bar to be damaged, prevent that clip is due to the factors such as pressure, the vibrations potential safety hazard that sliding transfer brings on crossbeam.
2, facilitate clip installing/dismounting and carrying.
