Abstract
The utility model relates to a conversion support for a large-span space crossed truss. The conversion support is characterized by consisting of a lattice temporary support and a top pitch point, wherein the lattice temporary support is formed by connecting a horizontal rod and a diagonal web member which respectively consist of a vertical circular pipe and double channel steel; and the top pitch point on the top of the lattice temporary support consists of a cutting plate welded on the top surface of the vertical circular pipe. The conversion support is characterized in that the cutting plate on the top surface of the vertical circular pipe is formed by welding a transverse erect thickened steel plate and four reinforcing steel plates which are perpendicular to the transverse erect thickened steel plate. The conversion support has the advantages that the problem that a main truss is installed after a secondary truss is installed due to the limit of fields and the problem of predeformation in truss span are solved; and the conversion support is safe, reliable and convenient to disassemble.
Description
Technical field
The utility model relates to a kind of conversion that is used for large span space intersection truss to be supported.
Background technology
Large span space intersection truss, main couple and jack truss square crossing form the monolithic stability system.When structure was installed, adopt installed main couple earlier more, and the method for jack truss is installed in the back.Because truss span is big, in the main couple installation process, occur easily that the distortion of main couple span centre is excessive, stress surpasses problems such as design load.The engineering that has, because the place restriction can only be installed jack truss earlier, main couple is installed in the back, makes the problem of truss distortion, the ultra design load of stress highlight more.Therefore demand urgently the installation of large span space intersection truss is improved, to solve the truss distortion that in carrying out the installation of large span space intersection truss, is produced at present, the problem of the ultra design load of stress.
Summary of the invention
The purpose of the utility model is to solve in the prior art to intersect at large span space that truss is existing when installing the problem that the distortion of main couple span centre is excessive, stress surpasses design load to occur, provides a kind of large span space that is used for to intersect the conversion of truss and support.A kind of conversion that is used for large span space intersection truss of the utility model design is supported; It is characterized in that: described conversion is supported by interim support of lattice and top node and is formed; Interim horizon bar, the diagonal web member be made up of vertical pipe and Two bors d's oeuveres channel-section steel of supporting of lattice connects to form, and is made up of the knife plate that is welded on the vertical pipe end face in the top node of the interim support, top of lattice.It is characterized in that: the knife plate on vertical pipe end face by one laterally erect add steel plate and four perpendicular reinforcement steel plates welding constitute.The utility model has the advantages that to have solved because of the place restriction that the essential jack truss of installation earlier is the problem of main couple again, solved the problem of truss span centre predeformation, this support pattern is safe and reliable, unloads carried convenient.
Description of drawings
Fig. 1 is the user mode sketch map of the utility model.
Fig. 2 is the top node structural representation of the utility model, and Fig. 3 is the vertical view of Fig. 2.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment
Conversion described in the figure is supported by the interim support 1 of lattice and is formed with top node 2; Interim horizon bar, the diagonal web member be made up of vertical pipe 3 and Two bors d's oeuveres channel-section steel 4 of supporting of lattice connects to form, and is made up of the knife plate 5 that is welded on the vertical pipe end face in the top node of the interim support, top of lattice.It is characterized in that: the knife plate on vertical pipe end face is welded with four blocks of perpendicular reinforcement steel plates 7 and is constituted by a steel plate of laterally erectting 6 that adds.
Operating principle is through the span centre at truss 8 at least one interim support to be set, and converts truss into the multispan continuous trusse by the truss of two ends freely-supported.The minimizing truss is installed distortion and is difficult to control, the ultra design load of stress because of span is excessive.In the conversion support top end knife plate of controlling absolute altitude is set, truss is carried out predeformation control.
During practical implementation, when truss is installed, earlier the truss two ends are shelved structurally, span centre is shelved on conversion and supports.After treating the structural system installation, carry out the unloading that the span centre conversion is supported again.During unloading, progressively cut off the top knife plate, make the final free downwarp of truss span centre, structural stress converts.
Through the method for interim support is set at the truss span centre, reduce the span of main couple or jack truss, span centre distortion of control truss and stress.This support pattern is safe and effective to distortion of control truss and stress, has also reduced the segmentation of truss, practices thrift duration and construction cost.
Claims (2)
1. a conversion that is used for large span space intersection truss is supported; It is characterized in that: described conversion is supported by interim support of lattice and top node and is formed; Interim horizon bar, the diagonal web member be made up of vertical pipe and Two bors d's oeuveres channel-section steel of supporting of lattice connects to form, and is made up of the knife plate that is welded on the vertical pipe end face in the top node of the interim support, top of lattice.
2. intersect the conversion of truss and support by the described a kind of large span space that is used for of claim 1, it is characterized in that: the knife plate on vertical pipe end face by one laterally erect add steel plate and four perpendicular reinforcement steel plates welding constitute.
