A kind of light section steel structure factory building wind-resistant column and roof girder syndeton
Technical field
The utility model belongs to the design of building structures field, is specifically related to a kind of light section steel structure factory building wind-resistant column and roof girder syndeton.
Background technology
It is more to use light section steel structure factory building such as portal-rigid frames in the nuclear power plant, because the specific (special) requirements of nuclear power plant's technology arrangement makes that the position that arranges of wind-resistant column can't be that wind-resistant column and a Pin axis of bent retreat spacing 600mm layout, the structure practice that causes wind-resistant column and roof girder can't adopt traditional spring leaf to be connected by the standard practice of general plant designing in some light section steel structure plant designings.
Because the variation of this layout, therefore to find out a kind of practice, make structure can satisfy the junction roof girder and vertically can move freely (distortion), the instructions for use of the horizontal loading that the horizontal direction wind-resistant column can be subjected to roof girder good communication wind-resistant column, effectively simple, easy construction again, operation is simple.
The utility model content
The purpose of this utility model is the particularity at existing practical problem, and the make that provides a kind of light section steel structure house wind-resistant column of practicality to be connected with roof girder satisfies the designing requirement of light section steel structure factory building.
The technical solution of the utility model is as follows: a kind of light section steel structure factory building wind-resistant column and roof girder syndeton, at roof girder bottom flange fixed-site connected node connector, Long Circle bolt hole longitudinally is set on the described node connector, and node connector is connected with the wind-resistant column web with bolt by the Long Circle bolt hole.
Further, aforesaid light section steel structure factory building wind-resistant column and roof girder syndeton, wherein, described node connector is channel-section steel.
Further, aforesaid light section steel structure factory building wind-resistant column and roof girder syndeton, wherein, described Long Circle bolt hole is symmetrical arranged along the node connector center line.
The beneficial effects of the utility model are as follows: the utility model has been broken through original traditional spring leaf connected mode, employing is provided with the channel-section steel of Long Circle bolt hole as connector, can be more convenient satisfy light section steel structure factory building wind-resistant column and can move freely (distortion) with being connected vertically of roof girder, the instructions for use of the horizontal loading that horizontal direction wind-resistant column and roof girder good communication wind-resistant column are subjected to.
Description of drawings
Fig. 1 is the front view of light section steel structure factory building wind-resistant column and roof girder syndeton;
Fig. 2 is the lateral plan of light section steel structure factory building wind-resistant column and roof girder syndeton.
Among the figure, 1. roof girder; 2. wind-resistant column; 3. bolt; 4. channel-section steel.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
The connected node of light section steel structure wind-resistant column and roof girder need provide following constraint for roof girder and wind-resistant column.At first, roof girder should be able to normally move up and down, and namely vertical direction is unfettered; Secondly, wind-resistant column will have reliable horizontal direction to support, and namely horizontal direction will have reliable constraint.
Light section steel structure factory building wind-resistant column provided by the utility model and roof girder syndeton are as shown in Figure 1 and Figure 2, at the bottom flange of roof girder 1 fixed-site connected node connector, node connector adopts channel-section steel 4(to be not limited to use channel-section steel certainly in the present embodiment, other rigid connector also can adopt), Long Circle bolt hole longitudinally is set on the channel-section steel 4, the Long Circle bolt hole can satisfy the vertical displacement of roof girder, and channel-section steel 4 is connected with the web of wind-resistant column 2 with bolt 3 by the Long Circle bolt hole.
In the present embodiment, two Long Circle bolts hole are set on the channel-section steel 4, are symmetrical arranged along the node connector center line.Erection bolt is connected wind-resistant column in the bolt hole with channel-section steel, and the upper surface of channel-section steel is welded in the roof girder bottom flange.This moment bolt can be in the Long Circle bolt hole easy on and off move the connection of satisfying roof girder and vertically can move freely (distortion), horizontal direction is limited by bolt hole to can be wind-resistant column to provide horizontal direction to retrain.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technology thereof, then the utility model also is intended to comprise these changes and modification interior.
