Description
Technical field
The utility model belongs to building structure field, and in particular to a kind of connection structure of large span steel truss and frame column
It makes.It is particularly suitable for span and load is larger, truss support chord member stress is larger and requires steel truss and feelings that frame column has just connect
Condition.
Background technique
Steel truss vertical rigidity is very big, bearing capacity is high, and can be used as equipment installation arrangement space between top-bottom chord, thus
Using more universal in building structure.When common large span steel truss and frame column just connect, column side top-bottom chord is whole in truss
Biggish local bending moment can be generated under the influence of body vertical deformation, thus top-bottom chord is respectively stretch bending and bending component.Steel truss
In order to increase structure rise as far as possible, top-bottom chord depth of section is usually smaller, therefore will also lead under the effect of lesser local bending moment
Cause section edges bending stress very big.Common steel truss support top-bottom chord, suffered moment of flexure and axle power are larger, according to side
Edge yield criterion winds up top flange under axle power and the effect of moment of flexure Stress superposition and lower edge lower flange is surrendered first, and material cannot fill
Divide and utilizes.
The utility model reinforces connecting plate by increasing between common steel truss support chord member, makes former truss top-bottom chord
It is linked together, common stress, so that the ability that steel truss end resists local bending moment is greatly strengthened, so that former stretch bending and press-bending
Chord member becomes simple bending girder steel (axle power very little), and flange stress is equal in magnitude up and down under Moment, and material use is more abundant,
It can solve the problems, such as common steel truss support chord member overstressing.
Summary of the invention
The purpose of this utility model is to provide the large span steel truss that a kind of support chord member is reinforced, with conventional steel truss phase
Than the reinforced steel panel point simple structure, truss end bearing capacity greatly reinforces.
The utility model adopts the following technical solutions: a kind of large-span steel that the support chord member just connect with frame column is reinforced
Truss, including frame column and steel truss, the end of steel truss are fixedly connected with frame column；The steel truss include top boom, under
Chord member, web member and the reinforcement connecting plate for connecting top boom and lower boom reinforce the top boom that steel truss end is arranged in connecting plate
Between lower boom, the upper surface and lower end surface for reinforcing connecting plate are aligned and use with top boom web and bottom chord web respectively
The pre-buried fashioned iron abdomen in frame column side and frame column outside steel pipe or frame column column of connecting plate is reinforced in full penetration connection
The connection of plate full penetration.
The support chord member reinforces connecting plate along the length of steel truss horizontal direction and is not less than steel truss height.
Increased reinforcement connection plate thickness needs to meet Steel Structural Design standard in the utility model reinforced steel truss
Section ratio of height to thickness requires (i.e. the 6.3.2 articles section ratio of height to thickness requirement of satisfaction " Steel Structural Design standard " GB50017-2017), from
Column side extension elongation takes two web members place length of support edges and not less than truss depth.
Length range where reinforcing connecting plate in the utility model reinforced steel truss should ensure that steel truss top-bottom chord passes through
It is logical.
Increasing after reinforcing connecting plate in the utility model reinforced steel truss, the former diagonal web member being overlapped with connecting plate is cancelled,
Simplify structure construction.
The utility model technology is advantageous in that: this support chord member reinforced steel truss makes to prop up because adding reinforcement connecting plate
Seat top-bottom chord is linked together, common stress, so that the ability that steel truss end resists local bending moment is greatly strengthened, so that former
Stretch bending and press-bending chord member become simple bending girder steel, and flange stress is equal in magnitude up and down under Moment, and material use is more abundant,
It can solve the problems, such as common steel truss support chord member overstressing.
Detailed description of the invention
Fig. 1 is the utility model organigram；
Fig. 2 is the A-A view of Fig. 1.
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
As shown in Figure 1 and 2, the utility model includes frame column 1 and steel truss, and the end of steel truss and frame column 1, which are fixed, to be connected
Connect (such as by steel truss wind up 2, truss lower edge 3 respectively with 1 full penetration strong weld of frame column).The steel truss includes winding up
Bar 2, lower boom 3, web member 4 and the reinforcement connecting plate 5 for connecting top boom 2 and lower boom 3 are reinforced connecting plate 5 and are arranged in steel truss
Between the top boom 2 and lower boom 3 of end, reinforce connecting plate 5 upper surface and lower end surface respectively with top boom web 2.1 and under
Chord member web 3.1 is aligned and is connected using full penetration, and that reinforces connecting plate 5 leans on 1 side of frame column and 1 Covered with Angles of frame column
Pre-buried shape steel web full penetration connection in pipe or frame column column.Connecting plate 5 is aligned and uses with truss top-bottom chord web
Full penetration, with frame column outside steel pipe full penetration.Reinforcing in connecting plate range (Fig. 1 center pillar side L range) above and below
Chord member perforation, the former web member at this are cancelled, and upper and lower chord member edge of a wing corresponding position is preferably provided stiffener 6 in frame column.
The support chord member reinforces connecting plate along the length of steel truss horizontal direction and is not less than steel truss height.
Increased reinforcement connection plate thickness needs to meet Steel Structural Design standard in the utility model reinforced steel truss
Section ratio of height to thickness requires (i.e. the 6.3.2 articles section ratio of height to thickness requirement of satisfaction " Steel Structural Design standard " GB50017-2017), from
Column side extension elongation takes two web members place length of support edges and not less than truss depth.
Length range where reinforcing connecting plate in the utility model reinforced steel truss should ensure that steel truss top-bottom chord passes through
It is logical.
Increasing after reinforcing connecting plate in the utility model reinforced steel truss, the former diagonal web member being overlapped with connecting plate is cancelled,
Simplify structure construction.
The utility model is linked together support top-bottom chord because adding reinforcement connecting plate, common stress, to increase
Strong steel truss end resists the ability of local bending moment, so that former stretch bending and bend chord member and become simple bending girder steel (axle power very little),
Flange stress is equal in magnitude up and down under Moment, and material use is more abundant, can solve common steel truss support chord member and answer
Power overrun issues.
The reinforced lattice construction is simple, only increases junction steel plate between conventional truss support chord member, but can cancel with
The diagonal web member that connecting plate is overlapped can be widely applied to just connect with frame column and load be larger to simplify support node construction
Large span steel truss structure in.
The utility model is that i shaped cross section is equally applicable for top-bottom chord so that top-bottom chord is box section as an example.
