Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Construction of the present invention steel column sectional shelf-unit used is formed primarily of steel strut 2, the bottom of every root steel strut 2 is connected with bracket basis 1 and is vertically fixed on bracket basis 1, connects the resistance to overturning ensureing steel column supporting structure between steel strut 2 by bearing diagonal 6.Steel strut 2 top can arrange distribution beam 3.Sandbox 5 or jack are directly or indirectly placed in distribution beam 3, the bridge superstructure deadweight and the working load that comprise steel girder box 7 (see Fig. 2) are delivered in distribution beam 3 by sandbox 5 or jack, then by distribution beam 3, load are distributed to each steel strut 2.
Apply steel column sectional shelf-unit construction provided by the invention when constructing, crossed over the both sides of road and/or as required in the road between set up steel column sectional shelf-unit respectively, Specific construction flow process mainly comprises: preparation of construction; Bracket basis process; Assembling steel column support; Distribution beam is set; Sandbox or jack are installed.
First, according to the establishment such as construction drawing design, site contour, pouring plan and appointed condition constructure scheme, and according to the intensity of the different construction stage support of construction stage load capacity calculation, rigidity and stability.According to working drawing, according to the strong point, measurement and positioning is carried out to the installation site of steel strut 2, guarantee the accurate of steel strut 2 position.
After preparation of construction work completes, bracket basis 1 is processed.Bracket basis 1 needs to be placed in meet on the ground of requirement for bearing capacity.In order to prevent basis in bridge construction process from occurring moderate finite deformation, can be clean by substrate eliminating impurities, substrate also can be avoided to be subject to water soaking and to endure cold.
After treating that bracket basis 1 process reaches the requirement of setting, namely can start to assemble steel column support.First, check that steel strut component used is to ensure that they do not have gross distortion and cross section to weaken.Then, accurate setting-out is carried out with the mounting plane control point of total powerstation to steel strut 2.Each steel strut 2 can be formed by connecting by multiple steel strut component.During assembling, adopt the form of merogenesis lifting steel strut component, first head is saved steel strut component to be connected with bracket basis 1 by basic built-in fitting such as pre-embedded bolt, then respectively connect with flange high-strength bolt between joint steel strut component at all the other, steel column top also can adopt flange high-strength bolt connected mode to be connected with top rail simultaneously, make the easy installation and removal of steel strut 2 quick like this, drastically increase operating efficiency.For increasing rigidity and quality of connection bottom steel strut 2, bottom steel strut 2, can be welded with triangular steel plate of putting more energy in surrounding and basic built-in fitting junction, such as, be four pieces.Remain during installation that steel strut 2 is vertical.For ensureing the stability of construction period support, bearing diagonal 6 is set between steel strut 2 in order to ensure the resistance to overturning of supporting structure.Steel strut component can adopt external diameter 609 millimeters, the pipe steel column of wall thickness 16 millimeters.
After steel column bracket assembled completes, steel strut 2 arranges distribution beam 3.First i iron can be set on every root steel strut 2 top or Bailey beam makes distribution beam 3, and distribution beam 3 is welded on steel strut 2 top.Distribution beam 3 can be arranged to semi girder.Sandbox 5 or jack are placed in distribution beam 3, as illustrated in fig. 1 and 2.Distribution beam 3 also can be arranged to simply supported beam, and now can weld spandrel girder again in distribution beam 3, sandbox 5 or jack are placed on spandrel girder.Alternatively, also distribution beam 3 can not be set, but load-bearing is carried out on top sandbox 5 or jack being directly placed on steel strut 2, as shown in Figure 3.Such as i iron can also be used multiple distribution beam 3 to be coupled together, thus formation working platform carry out load-bearing.
Structure and the making of the composite steel column support that construction of the present invention is used are simple, easy accessibility, and material can select pipe steel column and i iron, and these are all be easy to lease the material obtained, and significantly reduce use cost.
