Abstract
The utility model discloses a kind of pipe tie-rod, for connecting two columns of steel work, comprise that pipe, two junction plates and one end are connected with the excircle of pipe, the connecting portion that the other end is connected with one end of junction plate; Pipe and junction plate all seamlessly transit with the junction of connecting portion, and the plate face of junction plate is parallel with the axis of pipe, offers the through hole for connecting column on junction plate.Due to the bearing part that adopts hollow pipe to connect as two columns, the warp resistance moment that hollow pipe under equal in quality has, the ability of torsional moment are greater than solid hopkinson bar, be that its rigidity is greater than solid hopkinson bar, therefore, pipe tie-rod of the present utility model is unlikely to again the support load of too much increase column in can increasing by two column integral rigidities; In addition, because the junction of connecting portion and junction plate, pipe all seamlessly transits, in the time being subject to various load, this place can not concentrate and rupture because producing stress, thereby has increased the intensity of whole pipe tie-rod.
Description
Technical field
The utility model relates to a kind of steel structure connecting member, relates in particular to a kind of pipe tie-rod.
Background technology
In steel construction, have a lot for supporting the column of whole building, that every root post is subject to is conventionally very large, acting in conjunction in multiple directions, complex load, under the effect of load, single upright column does not have the distortion of enough large rigidity to stop column to produce conventionally.In prior art, conventionally connect two root posts to increase the integral rigidity of two root posts with some solid rod members, thereby make the whole building of the more stable support of column.But because solid hopkinson bar quality is very large, but increase the support load of column in increasing column rigidity, if select thinner solid hopkinson bar cannot meet again its rigidity requirement.
Utility model content
For the above-mentioned defect existing in prior art, the utility model discloses a kind of pipe tie-rod, this pipe tie-rod is unlikely to again the support load of too much increase column when can increasing by two column integral rigidities.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of pipe tie-rod, for connecting two columns of steel work, two junction plates and one end of comprise pipe, being symmetricly set on described pipe both sides are connected with the excircle of described pipe, the connecting portion that the other end is connected with one end of described junction plate; The junction of described pipe and described connecting portion seamlessly transits, and the junction of described junction plate and described connecting portion seamlessly transits, and the plate face of described junction plate is parallel with the axis of described pipe, offers the through hole for connecting column on described junction plate.
Preferably, all offer two described through holes on every described junction plate, two described through holes are arranged symmetrically with about the axis of described pipe.
Preferably, described pipe tie-rod integrated punching moulding.
Preferably, described pipe is coating steel pipe.
Compared with prior art, the beneficial effect of pipe tie-rod of the present utility model is: due to the bearing part that adopts hollow pipe to connect as two columns, according to theory of mechanics of materials, the warp resistance moment that hollow pipe under equal in quality has, the ability of torsional moment is greater than solid hopkinson bar, be that its rigidity is greater than solid hopkinson bar, in other words, in the situation that meeting same stiffness, the quality of hollow circular-tube is less than the quality of solid hopkinson bar, therefore, pipe tie-rod of the present utility model is unlikely to again the support load of too much increase column in can increasing by two column integral rigidities, in addition, because the junction of connecting portion and junction plate, connecting portion and pipe all seamlessly transits, in the time being subject to various load, this place can not concentrate and rupture because of generation stress, thereby has increased the intensity of whole pipe tie-rod.

Detailed description of the invention
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As Figure 1-3, an embodiment of the present utility model provides a kind of pipe tie-rod 10, for connecting two columns of steel work, comprise pipe 1, two junction plates 3 and one end of being symmetricly set on pipe 1 both sides are connected with the excircle of pipe 1, the connecting portion 2 that the other end is connected with one end of junction plate 3; Pipe 1 seamlessly transits with the junction of connecting portion 2, and junction plate 3 seamlessly transits with the junction of connecting portion 2, and the plate face of described junction plate 3 is parallel with the axis of described pipe 1, offers the through hole 31 for connecting column 5 on junction plate 3.Particularly, pipe tie-rod 10 of the present utility model can utilize the moulding of punching machine integrated punching, utilize punch forming so that junction plate 3 is connected more reliable with connecting portion 2, pipe 1 with connecting portion 2, junction transition is more level and smooth, be conducive to increase the intensity of pipe tie-rod 10 of the present utility model, and the stress of minimizing junction is concentrated.
As shown in Figure 4, pipe tie-rod 10 of the present utility model is connected between two columns 5 of steel construction, on column 5, be provided with the contiguous block (not shown) being connected with the junction plate 3 of pipe tie-rod 10, this contiguous block correspondence is offered through hole, junction plate 3 and contiguous block are connected and fixed by bolt.For making connection more firm, junction plate offers two and is arranged symmetrically with about the axis of pipe 1 for 31, two through holes 31 of through hole that connect, and accordingly, contiguous block is also offered two through holes for connecting.
Due to the bearing part that adopts hollow pipe 1 to connect as two columns, according to theory of mechanics of materials, the warp resistance moment M1 that hollow pipe 1 under equal in quality has, the ability of torsional moment M2 are greater than solid hopkinson bar, be that its rigidity is greater than solid hopkinson bar, in other words, in the situation that meeting same stiffness, the quality of hollow circular-tube 1 is less than the quality of solid hopkinson bar, therefore, pipe tie-rod 10 of the present utility model is unlikely to again the support load of too much increase column 5 in can increasing by two column 5 integral rigidities; In addition, because connecting portion 2 and junction plate 3, connecting portion 2 all seamlessly transit with the junction of pipe 1, in the time being subject to various load, this place can not concentrate and rupture because of generation stress, thereby has increased the intensity of whole bar.
