Abstract
The invention relates to a steel support structure capable of improving structural stress, in particular to a spatial truss with obliquely arranged main chords and capable of releasing horizontal force and a mounting method. The spatial truss comprises a temporary steel structural support and buried parts which are connected with and support supporting feet of the temporary steel structural support. The spatial truss is characterized in that shelving points are arranged on the temporary steel structural support and correspond to structural connecting joints on a high-altitude steel corridor; and the mounting method for the spatial truss with the obliquely arranged main chords and capable of releasing horizontal force includes that a supporting foot in the temporary steel structural support is welded with the corresponding buried part, then the high-altitude steel corridor is hoisted on the temporary steel structural support, the structural connecting joints on the high-altitude steel corridor are connected with the corresponding shelving points on the temporary steel structural support, and after load of the high-altitude steel corridor totally acts on the temporary steel structural support, the rest supporting feet of the temporary steel structural support are fixedly welded with the corresponding buried parts. The spatial truss with the obliquely arranged main chords and capable of releasing horizontal force and the mounting method have the advantages that the size of the section of the temporary steel structural support can be greatly reduced, and consumption of steel materials is reduced.
Description
Technical field
The present invention relates to relate to a kind of steel support structure that can improve structure stress, but particularly a kind of space truss and mounting method of oblique layout main chord of emission levels power.
Background technology
High-altitude steel vestibule structure can be used as the interface channel between the different buildings, and general steel vestibule adopts the form of steel work, supports to different architectural through support style.But often there is building structure construction progress difference, some supportings can occur and carry out, and other is also underway as supporting; This makes that the permanent supporting-point of high-altitude steel vestibule is imperfect; Support high-altitude steel vestibule and some temporary structures need be set, but, can produce very big moment of flexure shelving beam because high-altitude steel vestibule is very big to the load of respectively shelving generation a little; Therefore the now set general steel that consume of temporary steel structure stand are more; And because the leg of beam is shelved in the supporting of temporary steel structure stand is oblique, so can produce certain horizontal load to bottom embedded part structure, therefore set embedded part also need carry bigger horizontal load; If it is improper to be provided with; Possibly cause toppling of high-altitude steel vestibule because embedded part can't load level and rupture, the position and the correct construction technology of shelving a little that therefore high-altitude steel vestibule is set are the keys that solution high-altitude steel vestibule is shelved temporarily.
Summary of the invention
The objective of the invention is to solve prior art high and medium steel vestibule and shelve existing the problems referred to above temporarily, but a kind of space truss and mounting method of oblique layout main chord of emission levels power are provided.But the present invention designs a kind of space truss of oblique layout main chord of emission levels power; Comprise the temporary steel structure stand, connect the embedded part that supports temporary steel structure stand leg; It is characterized in that: on the temporary steel structure stand, be provided with and shelve a little, shelve a little with high-altitude steel vestibule on the structure connected node corresponding.But a kind of space truss mounting method of oblique layout main chord of emission levels power; It is characterized in that: a leg in the temporary steel structure stand is welded with corresponding embedded part; Then high-altitude steel vestibule is lifted on the temporary steel structure stand; With the connection of shelving on the structure connected node on the steel vestibule of high-altitude and the corresponding temporary steel structure stand; After the load of treating high-altitude steel vestibule all affacts the temporary steel structure stand, weld fixing to remaining leg of temporary steel structure stand with corresponding embedded part again.Advantage of the present invention is the sectional dimension that can reduce the temporary steel structure stand greatly, reduces the consumption of steel.
Below in conjunction with instance the present invention is made detailed operation instruction.
Description of drawings
Fig. 1 is temporary steel structure stand of the present invention and high-altitude steel vestibule putting position sketch map.
Fig. 2 temporary steel structure stand of the present invention schematic cross-section.
The specific embodiment
The embedded part 2,6 that comprise temporary steel structure stand 1 among the figure, connects supporting temporary steel structure stand leg be permanent supporting-point, it is characterized in that: setting shelves a little 3 on the temporary steel structure stand, shelve a little with high-altitude steel vestibule 4 on structure connected node 5 corresponding.But a kind of space truss mounting method of oblique layout main chord of emission levels power; It is characterized in that: a leg in the temporary steel structure stand is welded with corresponding embedded part; Then high-altitude steel vestibule is lifted on the temporary steel structure stand; With the connection of shelving on the structure connected node on the steel vestibule of high-altitude and the corresponding temporary steel structure stand; After the load of treating high-altitude steel vestibule all affacts the temporary steel structure stand, weld fixing to remaining leg of temporary steel structure stand with corresponding embedded part again.
Because it is shelving a little of being provided with on the temporary steel structure stand is corresponding with structure connected node on the steel vestibule of high-altitude; Can reduce the moment of flexure that high-altitude steel vestibule that the temporary steel structure stand born produces like this; The main load that lets the temporary steel structure stand born is shearing, thereby has reduced the sectional dimension of temporary steel structure stand greatly.Simultaneously owing to earlier one of them leg of temporary steel structure stand is carried out the welding with embedded part; After the load of treating high-altitude steel vestibule all affacts the temporary steel structure stand; Weld fixing to remaining leg of temporary steel structure stand with corresponding embedded part again; This moment, high-altitude steel vestibule discharged on incomplete fixing leg the horizontal force of temporary steel structure stand, had improved the force-bearing situation of temporary steel structure stand lower leg and embedded part, made all leg sectional dimensions to reduce; And the structural requirement of embedded part also can reduce, thereby greatly reduces the steel that consumed.
