Abstract
The utility model relates to a novel connection node suitable for an elliptical long hole of a positioning assembly plate, which comprises a cantilever truss component, peripheral components connectedwith the cantilever truss component and two connecting plates, and is characterized in that the positioning assembly plate is welded on the cantilever truss component and the peripheral components connected with the cantilever truss component, and is provided with a bolt hole of standard circle. The bolt hole of the standard circle and the elliptical long hole are respectively arranged at both ends of each connecting plate. When being fixed, the two connecting plates are respectively installed at both sides of the positioning assembly plate, and connected with the positioning assembly plate through bolts. The diameter of the bolt hole of the standard circle arranged on the positioning assembly plate is matched with the diameter of the bolts, and the length of the elliptical long hole is bigger than the displacement amount which can occur on the structure. The utility model has the advantage of satisfying the requirements for deformation, thereby reducing the additional stress of a structural member bar. In addition, a node mode does not need changing and secondary processing on an original structure, and has simple operation, just as connection between every two ordinary components.
Description
Technical field
The utility model relates to a kind of semi-girder truss truss member is connected with peripheral structure when installing node, particularly a kind of suitable " locating buck plate ellipse slotted hole " novel connected node.
Background technology
In the semi-girder truss construction of super-high building structure, owing to exist structure vertical deformation difference, thereby can cause that the distortion of semi-girder truss member, subsidiary stress increase the problem that causes trussed construction reliability and safety to descend.Therefore need design a kind of interim connected node that allows rod member to slide or rotate in the construction period of whole super-high building structure, final fixing semi-girder truss again after the different basic realization of the vertical variation of structure has also been eliminated subsidiary stress thus substantially.The general at present form of bearing pin node that adopts solves appeal construction difficult problem (see figure 1).In actual applications, bearing pin processing acquires a certain degree of difficulty, and bearing pin itself is longer, and the material of bearing pin is had particular requirement, so cost is very high.Installation aspect, bearing pin and pin-and-hole gap only are 0.5mm, belong to accurate the connection, thereby require very high to installation accuracy.Aspect the duration, when decision finally, need expend time in and again the junction plate of high-strength bolt connection be processed and drilling fixedly the time the semi-girder truss.
Summary of the invention:
The purpose of this utility model is the problem that there is structure vertical deformation difference in the semi-girder truss in the solution super highrise building semi-girder truss construction, and a kind of suitable " the oval slotted hole of location buck plate " novel connected node is provided.A kind of novel connected node that is applicable to the semi-girder trussed construction of the utility model design, comprise semi-girder trussmember, the surrounding member that is connected with the semi-girder trussmember, it is characterized in that: will locate buck plate be welded on the semi-girder trussmember with surrounding member that the semi-girder trussmember is connected on, offer the bolt hole of standard circular on this location buck plate.Other has two junction plates, and the two ends of every junction plate offer standard circular bolt hole and oval slotted hole respectively.In the time of fixedly, two junction plates are installed in the both sides of location buck plate respectively, and connect with bolt.The standard circular diameter of bolt hole and the diameter of bolt offered on the buck plate of location are complementary, and the length of oval slotted hole is greater than the contingent displacement of structure.Advantage of the present utility model is, because the existence of oval slotted hole so can make the semi-girder trussed construction can produce less displacement in construction period by oval slotted hole, is satisfied the requirement of distortion, thereby reduces the subsidiary stress of structural member.And this node mode must not change and reprocesses original structure, operates simple and easyly to have simplified difficulty of construction as the connection between the member, has saved a large amount of expenses.
Description of drawings:
Fig. 1 is the bearing pin node schematic diagram of prior art,
Fig. 2 is a structural representation of the present utility model,
Fig. 3 is a node schematic diagram of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment:
Comprise semi-girder trussmember 1, the surrounding member 2 that is connected with the semi-girder trussmember among the figure, it is characterized in that: will locate buck plate 3 be welded on semi-girder trussmember 1 with surrounding member 2 that the semi-girder trussmember is connected on, offer the bolt hole 4 of standard circular on this location buck plate 3.Other has two junction plates 5, and the two ends of every junction plate 5 offer standard circular bolt hole 6 and oval slotted hole 7 respectively.In the time of fixedly, two junction plates 5 are installed in the both sides of locating buck plate 3 respectively, and connect with bolt (drawing among the figure).Standard circular bolt hole 4 diameters and the diameter of bolt offered on the buck plate 3 of location are complementary, and the length of oval slotted hole 7 can make connecting bolt do certain slide displacement along oval slotted hole 7 greater than the contingent displacement of structure.When structure is interim connect after, along with the basic elimination of vertical deformation difference, final fixing semi-girder truss member again.
During construction, processing factory will locate earlier buck plate with semi-girder trussmember 1 and the surrounding member 2 that is connected with the semi-girder trussmember together make and welded and installed to the precalculated position.When semi-girder trussmember 1 (diagonal brace) with promptly will locate buck plate after the surrounding member 2 (bracket) that is connected with the semi-girder trussmember is alignd and fix with two junction plates 5, after dropping into bolt, an end of standard circular hole just twists then, regulate the joint gap of semi-girder trussmember 1 (diagonal brace) and the surrounding member 2 (bracket) that is connected with the semi-girder trussmember again, drop into bolt at oval slotted hole 7 places of the other end at last and carry out temporary fixed.
Claims (3)
