Summary of the invention
The purpose of this utility model is in order to solve the existing problem that support site assembly workload is big, number of fitting parts is many that is used for the concrete cast-in-situ mould bases of high ferro and overhead road of city, a kind of high ferro mould bases brace summer rational in infrastructure is provided, it is by type design plurality of specifications length, joint with quick connection, can be arbitrarily made with Len req, the bearing capacity of single beam is big, assembles easy for installation efficient.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of high ferro mould bases brace summer, comprise by two and go up plane steel I-beam in the same plane, it is characterized in that described steel I-beam on, be respectively equipped with cover plate on the lower plane, one end of steel I-beam is provided with first joint, the other end of steel I-beam is provided with second joint, first joint, second joint constitutes by two plates that are parallel to each other, interior Ullage between first joint, two plates is from greater than the outer lateral extent between second joint, two plates, first joint, second joint is provided with the connection pin-and-hole.This device is formed main framing by two i iron, cover plate is spliced into one to two i iron up and down, the size of first joint and second joint is a pair of size that cooperatively interacts, in many brace summer connection procedures, as long as second joint of a brace summer is plugged in first joint of another root brace summer, get final product with bearing pin or bolt connection.The length of single brace summer can design some kinds of length specifications from 1 meter to tens meters, and is required with the length that satisfies combination arbitrarily.
As preferably, the width of described cover plate equates with the width sum of two i iron wing plates.The both sides of cover plate and i iron welding, generally speaking, the width of cover plate is less than the width of two weld seams of i iron.
As preferably, two i iron webs that constitute in plate and the steel I-beam of described first joint be arranged in parallel; Two two of constituting the plate and first joint of second joint constitute the equidirectional setting of plate.When two I-shaped girder steels connect, connect bearing pin from side interts the hole of first joint and second joint, two planes of steel I-beam are provided with along the vertical direction.
As preferably, the position, two terminations of described steel I-beam is provided with end-plate, and first joint, second joint are connected with steel I-beam by end-plate respectively.First joint and second joint adopt sheet material system, all forms by two steel plates that are parallel to each other, the end of i iron can't be directly and flat-form material weld, end-plate must be housed.
As preferably, the web position, both sides of described steel I-beam is provided with some gussets.The length of steel I-beam does not wait from 1 meter to 12 meters, and gusset has been strengthened the curved intensity of doing of whole piece steel I-beam greatly, and gusset adds weldering in both sides again after two i iron splicings.
As preferably, described steel I-beam web position is provided with several hollow-out parts, and hollow-out parts is arranged between two adjacent gussets.Hollow-out parts can be removed the web that the steel I-beam anti-shearing force is not had influence, and hollow-out parts is made as circle or ellipse.
Effective effect of the present utility model is: a beam can replace double-deck a plurality of shellfish thunders, and installation, transportation, easy to assembly significantly reduce the site assembly workload.
