SU968233A1 - Butt joint of girder with twin-branch column - Google Patents

Description

The invention relates to the builder, the structure and can be used in the construction of shelves of the main buildings; Sov CHP ..

It is known to joint a beam with a column in which the beam is supported on the column console and rigidly connected to it by welding horizontal outlets of the reinforcement from the ends of the beam with the horizontal outlets of the reinforcement from the columns ijl}.

The disadvantage of this joint is the appearance of an additional moment in the column from the eccentric application of the vertical load from the beam to the column.

When the beam is supported on a two-legged column, this disadvantage is aggravated by the fact that the load is transmitted to one of its branches.

The closest technical solution to the invention is a butt joint of a beam with a two-leg COLUMN, comprising a column supporting element and a bore part of a 1 / 2J beam.

The disadvantage of the known joint is the high intensity and material intensity, which is necessary to ensure the joint operation of the two branches of the column as a whole section.

The aim of the invention is to simplify the connection while reducing material consumption.

This goal is achieved by the fact that in the butt joint of a beam with a two-leg column, including the column support element and the beam support part, the column support element is made in the form of a jumper in a two-leg column, and the support part of the beam is in the form of a fork, which wraps around the column and is attached to the jumper In addition, the cable is connected to the branches by 20 columns of the column with the help of overlays.

FIG. 1 depicts x; a detached connection of a bolt with column I in FIG. 2, section A-A in FIG. 1. longitudinal

incision; in fig. 3 is a section BB in FIG. 1, a longitudinal section, in FIG. Section B-B in FIG. 1, a cross-section.

Beam 1 is installed so that it wraps around the fork 2 with a two-legged column 3. The beam is supported on the column centrally and pivotally through the tables k, which are symmetrically attached to the bridge 5 of the column 3. Through these tables, the vertical load is transmitted from the beam to the column. The walls of the beam are made in the form of a fork and are pruned for a long time. possibility of installing tables ,.

Opposite the upper and lower beams, lining 6 is installed, which transmits the reference moment — from (ak to the column as a pair of forces. The plates 6 are attached to the beam itself and to the mortgages in the branches of the column,

The joint is carried out as follows.

First, a beam is installed on the column, hinging it on the tables welded to the column. Then install the plates, weld them to the branches of the column,

/ | This butt joint facilitates the construction of the frameworks of the main buildings of CHP plants, designed, for example, from squared structures, as it allows, on the one hand, to centrally transfer the vertical load on the squared columns from the bolts, and on the other hand, allows the shelf to work as rigid multi-storey frame from the influence of horizontal forces (wind and cranes).

The use of this joint allows up to 15% reduction in the consumption of materials for the skeleton of the main building of the CHP.

invention formula

The butt joint of a beam with a two-legged column, including a column supporting element and a beam supporting part, is characterized in that, in order to simplify the connection while simultaneously reducing material consumption, the supporting element of the column is made as a jumper in a two-legged column, and the supporting part of the beam is in the form of a fork spanning the column and reversed to the lintel, and from the beam to it is connected to the branches of the column with the help of overlays.
