Abstract
The utility model relates to the steel structure technological field, specifically to a truss-type steel support, solving the problem of small safety factor due to the application of long thin poles to form enclosure protective frames of subway ground pits or large deep ground pits. The truss-type steel support comprises a cuboid composed of four rectangular side plates, and is characterized in that two ends of the cuboid are equipped with parallel flanges, four sides of bores of the flanges are respectively connected with ends of the four side plates, four small cuboids which are formed by oppositely buckling notches of two channel steels are arranged in the cuboid constituted by the side plates, and the small cuboids are respectively located at four inner corners of the cuboid constituted by the side plates. The small cuboids which, in the inner hollow part of the cuboid, are formed by buckling and welding the channel steels significantly enhance the anti-compression, anti-bending and anti-torsion ability of the integral support. In addition, outer surfaces of the side plates are equally divided according to the length of the steel support, and are equipped with central horizontal cleats and diagonal cleats, achieving excellent strength and rigidity. Two ends of the steel support adopt multiple flexible connection modes such as flanges and Bailey pins, making the installation convenient.

Summary of the invention
The objective of the invention is to use long thin bar to cause the little problem of safety factor for the support of going along with sb. to guard him that solves subway foundation pit or large-scale deep foundation ditch, provide a kind of truss shaped steel of reasonable in design to support, it is a kind of space truss type structure, can increase resistance to compression and anti-intensity, the rigidity of turning round, structure fabrication is simple, and is easy for installation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of truss shaped steel supports, comprise the cuboid of forming by the square side plate of four block lengths, it is characterized in that described cuboid two ends are provided with the flange that is parallel to each other, the endoporus of flange is a quadrangle, endoporus four limits of flange are connected with the end of four side plates respectively, be provided with four by the relative little cuboid that forms that fastens of two channel-section steel notches in the rectangular formula body that side plate is formed, little cuboid lays respectively at four angles of the cuboid inside of side plate composition.The trussed construction of hollow, its horizontal combination cross section is a bearing surface, hollow inside fastens resistance to compression, bending resistance, the anti-twisting property that the little cuboid that is welded into has been strengthened integrated support greatly by channel-section steel, and carry out five equilibrium at the side plate external surface by the steel bearing length and install middle rail, diagonal cleat additional, make simple, strength rigid is good, and steel supports two ends and adopts multiple types of attachment such as flange, Bei Lei pin flexible and changeable, brings convenience for on-the-spot the installation.
As preferably, the length of described channel-section steel equates with distance between two flanges.The length of a weld seam of end indentation flange face of channel-section steel length during actual fabrication, flange is provided with connecting hole.
As preferably, described side plate surface is divided into several five equilibrium length along its length, at interval first diagonal cleat, second diagonal cleat is set in each five equilibrium length, is provided with middle rail between first diagonal cleat and second diagonal cleat.First diagonal cleat, second diagonal cleat and middle rail all adopt angle steel to make.
As preferably, described first diagonal cleat, second diagonal cleat are separately positioned in the rectangular planes of being made up of adjacent two middle rails, and are provided with along the rectangle diagonal.This diagonal setting i.e. first diagonal cleat becomes circular array with second diagonal cleat, and adjacent diagonal cleat becomes circular array successively continuously.
As preferably, described middle rail is axially vertical with side plate, and first diagonal cleat is connected with an end of middle rail with an end of second diagonal cleat, and first diagonal cleat and the second diagonal cleat other end are connected with adjacent middle rail respectively.All weld at first diagonal cleat, second diagonal cleat and middle rail handing-over position, increases overall construction intensity.
As preferably, several connecting holes evenly distribute on the described flange.Flange cooperates with flange during a plurality of steel support and connection, and steel supports when two ends cooperate and can exchange.
As preferably, a described end flanges is provided with male joint, and other end flange is provided with female joint, and described male joint and female joint cooperatively interact.By this male joint and the female joint mode that is connected, use the bearing pin socket, the efficient height during support and connection of more piece steel.
Effective effect of the present utility model is: increases the resistance to compression of going along with sb. to guard him supporting, anti-ly turned round ability, and simple in structure, easily make, easy for installation.
