Abstract
The utility model discloses a novel expansion joint of longitudinal supporting rod pieces with a steel structure, which is characterized in that an expansion link is increased between the adjacent longitudinal supporting rod pieces on both sides; both ends of the expansion link are partly overlapped with the longitudinal supporting rod pieces on the corresponding sides; and on the overlapping sections, the expansion link and the longitudinal supporting rod pieces are respectively provided with a group of slot holes of which the positions correspond mutually. The expansion joint is overlapped with the longitudinal supporting rod pieces by a connecting bolt passing through the slot holes. The material of the expansion joint is the same as that of the longitudinal supporting rod pieces, but the mechanical property of the cross section of the expansion joint is weaker than that of longitudinal supporting rods and the expansion joint has excellent expansion property. The design structure can effectively release temperature stress so as to meet free expansion amount of the steel structure under the condition of large temperature difference to protect a main rigid frame structure from being influenced.
Description
Technical field
The utility model relates to a kind of novel telescopic joint of steel work longitudinal bracing rod member.
Background technology
In the color structural steel design construction in recent years, color steel work length overall can surpass (80～100) rice mostly, big temperature difference per day because of the seasonal temperature difference or winter, summer, just cause steel work under powerful thermal stresses effect, flexible push-and-pull will cause vertical connecting rod distortion and local bolt to cut off, and is especially more general in regional this phenomenons such as the bigger Xinjiang of seasonal temperature, northeast, southwest, northwests.The Xinjiang winter summer temperature difference can reach 60 °～92 ° [summer+(35～52) ℃, the winter-(25～40) ℃], calculate as make the installation length formula by the steel work that adopts usually in the design now (by moderate-length, 15 internodes, 6 meters meters of each internode):
L＝24·N÷[(0.0921·k·ΔT)-1]
＝24×15÷[0.0921×1×(60～92)-1]
＝79m～48m
(annotate: k is a steel work environment coefficient of utilization, gets k=1.0 in the open)
Every 80m～50m the shrinkage joint will be set one like this, the junction, edge of adjacent two sections steel work will respectively be provided with a Pin main steel frame.
And the steel work longitudinal bracing rod member technology that adopts at present is to make a call to two little elliptical apertures 3 on locating the linkage section of vertical supporting bar 1 of 2 of two Pin master's rigid frames at the shrinkage joint, overlaps by the connecting bolt that penetrates, referring to shown in Figure 2; Or connect with steel plate lid; These ways are in fact very little to the push-and-pull action of alleviating thermal stresses, the big area of the temperature difference particularly, and the steel work stroke is very big, because removing measure can not follow up, tends to cause vertical supporting bar end arch sudden change shape.Still there is bigger secondary stress in the original structure and make, stressed unfavorable to entire infrastructure.
Summary of the invention
The purpose of this utility model provides a kind of novel telescopic joint of steel work longitudinal bracing rod member, and it can overcome the deficiencies in the prior art, thereby effectively takes precautions against the destruction that dilatation that thermal stresses causes steel work is limited to cause steel work.
For achieving the above object, the utility model is taked following design scheme:
A kind of novel telescopic joint of steel work longitudinal bracing rod member, it is to increase by an expansion coupling between the longitudinal bracing rod member of both sides adjacency, the longitudinal bracing rod member overlap joint of the two ends of this expansion coupling and homonymy; Overlapping section mutually, respectively having the slotted hole of one group of position correspondence on this expansion coupling and the longitudinal bracing rod member, expansion coupling and longitudinal bracing rod member are by passing the connecting bolt overlap joint of slotted hole.
Described expansion coupling material is identical with the vertical supporting bar material, but the mechanical property weakness of expansion coupling section is in vertical supporting bar, and both unanimities of telescopicing performance.
2～3 in a described group leader hole is good; Pass should be long ellipticity.
The design of the novel telescopic of the utility model steel work longitudinal bracing rod member joint, effective release temperature stress, thus satisfy the free stroke of steel work under the big temperature difference.
The utility model has the advantages that:
1, result of use is good, can reach the purpose of long-term protection.
2, protect main rigid frame freely to stretch effectively, and be not subjected to the effect of secondary stress, monolithic architecture is more firm, safer.
Description of drawings
Fig. 1 is the novel telescopic joint structural representation of the utility model steel work longitudinal bracing rod member.
Fig. 2 is the structural representation of prior art steel work vertical supporting bar.
Below in conjunction with drawings and the specific embodiments the utility model is described in further details:
The specific embodiment
Chief creating point of the present utility model is: be to increase by an expansion coupling between the longitudinal bracing rod member of both sides adjacency.
Consult shown in Figure 1ly, it is an example structure schematic diagram of the utility model novel telescopic of the steel work longitudinal bracing rod member (joint).Between the vertical supporting bar 2,3 between two adjacent Pin master's rigid frames 5 of shrinkage joint and between the wall purlin expansion coupling 1 is being set one, longitudinal bracing rod member 2,3 overlap joints of the two ends of this expansion coupling 1 and homonymy; Overlapping section mutually, respectively having the elongated hole 4 of one group of position correspondence on this expansion coupling and the longitudinal bracing rod member, expansion coupling and longitudinal bracing rod member are by passing the connecting bolt overlap joint of elongated hole.
The length of expansion coupling is decided by the length of two adjacent vertical structure segmentations and local Daji's temperature difference, is generally 300 millimeters～500 millimeters, also can be long or short.And the material of this section expansion coupling should be identical with former rigid frame, but section is thinner, more weak (the mechanical property weakness that is section is in vertical supporting bar or wall purlin), and both unanimities of telescopicing performance.And respectively offer the big elliptical aperture of a group leader and penetrate connecting bolt by correspondence position on expansion coupling and longitudinal bracing rod member the longitudinal bracing rod member of main rigid frame is linked to each other; as thermal stresses when overload appear; the weak section rod member of expansion coupling at first expands; can protect main rigid-framed structure effectively, thereby main rigid-framed structure is not subjected to the effect of secondary stress.
A described group leader hole is preferably more than two, and 2～3 is good; Pass should be long ellipticity.
The various embodiments described above can not break away under the scope of the present utility model in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit claim of the present utility model.
