Abstract
A steel structured sliding tree like support. The body of a sliding shoe takes the shape of a regular four edges pyramid, the prisms of which are four steel bars, the upper ends of which gather around the central steel bar and the four lower ends of which are connected with the upper parts of four supporting legs under the quadrilateral frame. The lower end of the long side of the quadrilateral frame is fixed and connected with a top plate of a hydraulic jack; the outer side face of the short side is fixed and connected with a pulling bar; and the front of the quadrilateral frame is articulated with a supporting bar, the upper end of which is connected with the extension board of a top supporting board which is the body of the sliding shoe. The utility model enhances the stability and stiffness of the structure, which makes the truss sliding system more stable and better load transferring stress. The main load transfers from the sliding system to the sliding shoe, and the stress of a roof truss structure reduces. The number of welds that are connected with the down chord of the truss greatly reduces, which is favorable for the recover of the structure appearance and the structure welding operation. Placing the pulling bar between every group of sliding shoes of a treelike supporting reduces the load transfer height, moment and the stress of the truss chord bars.
Description
(1) technical field
The utility model relates to a kind of construction steel structure supporting member, and particularly steel work supports.
(2) background technology
In the steel building work progress, steel roof truss can adopt high-altitude accumulation slippage method to install.When truss span is big, need set up together interim slideway and support thereof at span centre, this slideway generally is a level.When the lower edge of steel roof truss is not level, need between steel roof truss and interim slideway, the support piston shoes be set, with the levelling absolute altitude.The main body of the general support piston shoes of using always is the vertebral body shape, this support piston shoes are for the slippage of large-scale degree of uprising bidirectional stress steel roofing truss, because it is highly bigger, the distortion of propeller root structure is relatively large, the stationarity that is unfavorable for slippage, also have Load Transfer stressed also not good enough, the defective that the weld seam quantity that is connected with the truss lower edge is too many, welding capacity is quite big, be unfavorable for structure recovery.For example, in the engineering of the Wukesong Indoor Stadium of one of main venue of Beijing Olympic Games, the steel roofing truss is two-way quadrature truss stress system, and two-way span is 120 meters, and truss space is 12 meters, has 26 Pin.This truss cross section is fish-bellied type degree of uprising a bidirectional stress truss, and the truss cross section has seven kinds of forms, and bearing place height is 6.3m, and the span centre height does not wait from 6.3m～9.3m.For realizing the installation of Wu Ke Song steel roof system, adopted three slideway high-altitude accumulation slippage methods, transmeridional span centre sets up the interim slideway support system of being made up of 11 lattice columns and intercolumniation truss to need in the sports palace for this reason.Because steel roofing truss lower edge is the fish belly shape, height changes to 9.3 meters by 6.3 meters, and sliding rail must be a level, thus need between steel roofing and interim slideway, the support piston shoes be set, with the levelling absolute altitude.As adopt the tree-shaped support piston shoes of the back taper bodily form, then the normal pressure in preceding two groups of tree-shaped supports is not enough to tree-shaped support is pushed down in progradation, may be that hinge rotates with the tie point of top and truss.Therefore, the tree-shaped interim support piston shoes of the back taper bodily form can not be fit to needs.
(3) utility model content
The purpose of this utility model provides the tree-shaped support of a kind of steel work slippage, solves the problem that structural stability is not enough, the stressed weld seam quantity not good enough, that be connected with the truss lower edge of Load Transfer too many, welding is inconvenient.
The technical solution of the utility model: the tree-shaped support of this steel work slippage, be welded into the piston shoes main body by steel rod elements, top bracing plate| is arranged at piston shoes main body top, the piston shoes lower body part has leg, it is characterized in that: the piston shoes main body be shaped as positive four rib centrums, constitute four prisms of positive four rib centrums by four steel poles, the upper end of four prisms comes together in around the center steel column at top, four lower ends of four prisms are connected to four leg tops of quadrilateral frame bottom, be fixed with the hydraulic jack top board below the long limit of quadrilateral frame, the minor face lateral surface of the quadrilateral frame pull bar that is connected, the hinged supporting rod of the front end of quadrilateral frame, the upper end of supporting rod is connected with the extension plate of piston shoes main body top bracing plate|.
Be connected backing plate between four lower ends of above-mentioned four prisms and four legs of quadrilateral frame, between backing plate and the leg, be connected with stiffener between backing plate and the prism.
Be connected by riser between the long limit of above-mentioned hydraulic jack top board and quadrilateral frame.
Be connected floor between the top bracing plate| at above-mentioned center steel column and top.
The utility model is compared the beneficial effect that has with existing conventional art: structural stability strengthens, and the rigidity of structure increases, and steel roofing truss slippage system is more tended towards stability; Load Transfer is stressed better, and primary load is by slippage measure system-piston shoes transmission, and roof truss structure is stressed to be reduced; The weld seam quantity that is connected with the truss lower edge reduces significantly, both has been convenient to the recovery of structure outward appearance, also makes things convenient for the structure welding operation.Cylinder lever connecting rod between every group of tree-shaped support piston shoes has reduced the Load Transfer height, has reduced moment, and it is stressed to have reduced chord member of truss.The hydraulic jack top board that is connected below the long limit of quadrilateral frame is convenient to support as interim with hydraulic jack when the steel roofing unloads.In addition, the front end increase supporting rod every group of tree-shaped support rotates to prevent tree-shaped support.
