Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of structure simple, and easy to install, structure fastness is good, intensity large, can reduce traffic cost, can the assembly type standard knot of dismounting easily.
The purpose of this utility model has been come by following technical solution, described a kind of assembly type standard knot, it is connected in sequence mutually primarily of four standard nodal plates, described standard nodal plate comprises a main swing arm, one side in the upper, middle and lower portion of this main swing arm is connected to respectively upper brace, middle cross bar and a lower brace, and the other end of described upper brace, middle cross bar and lower brace is connected to the connecting strap of a slice and main swing arm horizontal simultaneously; Main swing arm another with install brace, middle cross bar and the side of lower brace and become 90 degree of sides are welded a slice and to match with described connecting strap and the fixed plate that is fixedly connected with connecting strap of available bolt.
Main swing arm described in the utility model is a square tube, and its one end is provided with the connector of evagination, and the other end is provided with can for the connecting bore of connector grafting; The top of described main swing arm or a side of bottom are connected to the secondary bar of a level, the other end of the secondary bar of this level is connected to one piece and connects square piece, be connected to a vertical joint bar between this connection square piece and described connecting strap, and be in described fixed plate on described main swing arm and same side be welded a slice and match and available bolt and the fixing square piece being connected square piece and being fixedly connected with the described square piece that is connected.
Connecting strap described in the utility model is oblong connecting strap, the other end of upper brace, middle cross bar and lower brace is connected to one side of described oblong connecting strap from top to bottom in turn, described connecting strap and fixed plate, is connected square piece with being connected in square piece and offers bolt hole accordingly respectively; The secondary bar of described level is fixedly connected at the top of main swing arm; The upper end of described main swing arm is provided with connector, and is provided with connecting bore in its lower end, and laterally starts accordingly to have on described connector and connecting bore and wear the fixed bolt fixing hole of fixed.
Described connecting strap and fixed plate, be connected square piece and be connected square piece, respectively by bolt, adjacent standard nodal plate connected to form standard knot, the upper end of two main swing arms positioned opposite, the relative arm of angle are welded with the connecting panel of an evagination respectively wherein, be configured with between two pieces of connecting panels one can from embed two pieces be in same straight line upper junction plate be embedded plate, and fixing with bolt after two pieces of connecting panels are fixed together.
The utility model belongs to and improves the one of prior art, and it is simple that it has structure, and easy to install, structure fastness is good, intensity large, can reduce traffic cost, can the feature such as dismounting easily.
