Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of hard horizontal beam inverted column installs bracing frame, as shown in figs. 1 to 6, innovation of the present utility model is: comprise base 11, long stent 5 and short support 7, the middle part of base is provided with one for the supported hole 18 of supporting traverse collapsible 1, two relative sides of base fill short support by bolt 10 symmetry hinge, another two relative sides of base are by bolt symmetry hinge dress long stent, and the upper end of the upper end of two long stents and two short supports installs the standing screw 4 for fixed cross beam collapsible respectively.
The structure of base is as shown in Figure 4: comprise trapezoidal crossbeam 14 and trapezoidal longeron 16, trapezoidal crossbeam and trapezoidal longeron to be interfixed composition by connecting panel 17 by two angle steel be parallel to each other, trapezoidal crossbeam and trapezoidal longeron are mutually fixedly mounted with and form a cross bar, trapezoidal crossbeam is an entirety, trapezoidal longeron is that the welding of polylith angle steel is made, in order to improve the stable connection between trapezoidal crossbeam and trapezoidal longeron, the position connected at trapezoidal longeron and trapezoidal crossbeam is provided with Angle connection plate 20, and reinforced rib 15 is all fixedly mounted with between trapezoidal crossbeam and adjacent trapezoidal vertical beam, formed the supported hole being used for supporting traverse collapsible by the split of polylith angle clip 19 in the center of cross bar.
Length due to horizontal beam inverted column has a variety of, so the commonality in order to strengthen bracing frame, long stent is made up of trapezoidal long frame 23 and two angle steel chutes 22, the dual-side lower end spacing angle steel chute that is slidably installed respectively of trapezoidal long frame, the lower end hinge of two angle steel chutes fills the end of trapezoidal crossbeam in the base, above-mentionedly spacingly be slidably installed structure specifically: a sidewall of angle steel chute is shaped with long through-hole 9, another sidewall is shaped with from top to bottom multiple round tube hole 8, the lock bolt 21 installed in long through-hole and round tube hole also makes trapezoidal long frame and angle steel chute fix.
Short support is made up of trapezoidal short frame 24 and two angle steel chutes, the dual-side lower end spacing angle steel chute that is slidably installed respectively of trapezoidal short frame, the end of the lower end hinge dress trapezoidal longeron in the base of two angle steel chutes, the structure in the spacing slide construction of trapezoidal short frame and angle steel chute and long stent is identical.
In the upper end of trapezoidal long frame and trapezoidal short frame, horizontal gird 12 is all installed, each horizontal gird is all shaped with screw vent 6, when after the supported hole that the lower end of collapsible is positioned in the middle part of base, trapezoidal long frame and trapezoidal short frame are to horizontal beam inverted column rotation, after four supports contact with horizontal beam inverted column outer wall, in the water balance beam of relative trapezoidal long frame and trapezoidal short frame upper end, multiple screw rod is installed with the upper end of fixed cross beam collapsible, such horizontal beam inverted column entirety is supported, load such as bracket 3 grade on horizontal beam inverted column need not be dismantled, stretcher 13 on trapezoidal long frame is demountable.
When constructing, the bracing frame fixing horizontal beam inverted column being placed on the lifting table of rail vehicle, slowly rising, then make horizontal beam inverted column and hard crossbeam 2 precisely contraposition, as long as the two fixes by workman, very convenient.
When horizontal depth of beam or position need adjustment, only need unclamp crossbeam, after height crossbeam being adjusted to needs on horizontal beam inverted column by the cooperation of groove and ball and level attitude, then crossbeam is locked on cross beam and upright post.
The utility model structure is simple, with low cost, use the lower end of base fixed cross beam collapsible, long and short support is used to cooperatively interact the upper end of fixed cross beam collapsible, energy safety, the stable whole collapsible of support, and the load such as bracket on horizontal beam inverted column need not be dismantled, no matter that installation or the dismounting of horizontal beam inverted column all can complete by bracing frame is disposable, several workmans are only needed in whole process, and the labour intensity of each workman reduces greatly, the installation of horizontal beam inverted column simultaneously can realize locating accurately.
