Description
Technical field
The utility model relates to the steel element structure of building, relates in particular to the truss-like roof truss structure of Collapsible building steel roofing.
Background technology
Existing roof truss mainly can be divided into two kinds of real abdomen formula and lattices, and wherein lattice adopts one or more materials such as formed channel steel, angle steel, square tube, garden pipe to be welded more.A kind of triangular truss formula roof truss in the prior art, its upper chord and lower chord all adopt the shaped steel in C type cross section, and its web member then adopts angle steel, and during making, web member can only monolaterally be welded on upper chord and the lower chord.The triangular roof truss of this structure is asymmetric because of web member and solder side thereof, and web member is not in the roof truss principal plane, causes unbalance stress, and profile is not attractive in appearance yet, and more because of the section bar kind in addition, material can not make full use of, and causes steel using amount big, and cost is higher.In addition, as shown in Figure 1, the two ends of this roof truss are respectively to weld a junction plate 7 by front and back will go up lower edge 81 and 82 and be fixed together, and when being connected with column 9, need angle sign indicating number 91 of welding on column 9, and be fixed on this angle sign indicating number 91 by the lower edge 82 of bolt with roof truss, below, roof truss end, needs at the bight of partition wall gap when below roof truss partition wall being installed with regard to out-of-flatness like this, construction is inconvenient, has not only increased man-hour but also not attractive in appearance.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of stressed even, lightweight triangular truss formula roof truss.
Another technical problem to be solved in the utility model is to provide a kind of and the smooth triangular truss formula roof truss in bottom surface, column junction.
The technical scheme in the invention for solving the above technical problem is, manufactures and designs a kind of triangular truss formula roof truss, is linked to be triangular roof truss by the connection web member between two C shaped steel upper chords and C shaped steel lower chord and upper chord and the lower chord; The both ends of described triangular roof truss are provided with the connector that is connected with column; It is characterized in that: the notch of described upper chord and lower chord is relative, and described web member adopts the C shaped steel of width less than described upper chord and lower chord notch, and the upper and lower end parts of described web member is inserted respectively and is weldingly fixed in the groove of described upper chord and lower chord.Web member can be welded on symmetrically the lower chord both sides thus.
Described connector comprises U type clamping plate and vertical junction plate, the opening of described U type clamping plate is trapped among in its groove inwardly and with the end clips of described upper chord and lower chord, the outside that described junction plate is fixed in U type clamping plate be used for column on vertical junction plate be connected by bolt.
Described junction plate is vertically fixed on the lateral surface middle part of described U type clamping plate, and the bottom of this junction plate is higher than the bottom surface of described lower chord.Roof truss and column junction below does not have protruding member like this, does not influence the installation of partition wall.
In order to make roof truss and column junction more attractive in appearance, the bottom of described vertical junction plate is provided with opening U-shaped supporting plate up, and its bottom surface is concordant with the bottom surface of described lower chord.
The top equidistant placement of described upper chord is useful on the fixedly angle steel purlin holder of purlin.
Compare with prior art, the web member of triangular truss formula roof truss of the present utility model adopts C shaped steel, and both sides all can be welded on the lower edge, thereby make force structure evenly reasonable, and profile is more attractive in appearance; The connector at roof truss two ends adopts U-shaped clamping plate and last lower edge to weld together, and makes lower edge keep same plane, and makes welded construction more reasonable.Being connected by being connected with bolt with junction plate on being fixed on column at the junction plate of U-shaped clamping plate external welding of roof truss and column, dismounting is all very convenient; The bottom of roof truss and column junction does not have protruding member, need not gap when partition wall is installed, and convenient and quick construction and wall leveling are attractive in appearance; In addition, because the single section bar that the roof truss each several part adopts, thereby can make full use of raw material, and help the batch production batch process.
Description of drawings
Fig. 1 is the structural representation of prior art intermediate cam shape truss-like roof truss and column junction;
Fig. 2 is the structural representation of triangular truss formula of the present utility model roof truss end and column junction;
Fig. 3 is the stereogram of triangular truss formula roof truss of the present utility model.
The specific embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
As shown in Figure 3, triangular truss formula roof truss of the present utility model connects into triangular roof truss by two upper chords 1 and a lower chord 2, connect some web members 3 between described upper chord 1 and the lower chord 2, upper chord 2 top equidistant placement are used for fixing the angle steel purlin holder 6 of purlin, and the both ends of described triangular roof truss also are provided with the connector 5 that is used to connect column.C shaped steel is all adopted in above-mentioned upward lower chord 1 and 2, web member 3 and purlin holder 6.Wherein: described upper chord 1 is relative with the notch of lower chord 2, and the width of described web member 3 is less than or equal to the width of rebate of described upper chord 1 and lower chord 2, and its upper and lower end parts is inserted in respectively in the groove of described upper chord 1 and lower chord 2.
As shown in Figure 2, described connector 5 comprises U type clamping plate 51 and vertical junction plate 52, the opening of described U type clamping plate 51 inwardly and with the end clips of described upper chord 1 and lower chord 2 in its groove and welding fixing, 52 welding of described junction plate are fixed in the lateral surface middle part of U type clamping plate 51, have on it a plurality of bolts hole be used for be fixed on column 4 on vertical junction plate 41 be connected by bolt, and the bottom of this junction plate 52 is higher than the bottom surface of described lower chord 2.Smooth attractive in appearance for the bottom that makes roof truss and column 4 junctions, the bottom of described vertical junction plate 52 is provided with opening U-shaped supporting plate 53 up, and makes the bottom surface of this U-shaped supporting plate 53 concordant with the bottom surface of described lower chord 2.Described U-shaped supporting plate 53 both can be fixed on vertical junction plate 52 bottoms of roof truss, also can be fixed on vertical junction plate 41 bottoms of column 4, when U-shaped supporting plate 53 is fixed on the bottom of junction plate 41 of column 4, the time marquis that roof truss is installed, this U-shaped supporting plate 53 can play the effect of temporary transient rest roof truss, is convenient to the operations such as contraposition calibration of two vertical junction plates 52 and 41 upper bolt holes.
As shown in Figure 2, when roof truss is connected with column 4, the vertical junction plate 41 in welding one strap bolt hole on column 4 gets final product vertical junction plate 52 overlap joints and both the bolt hole contraposition calibration back of this vertical junction plate 41 with roof truss with bolt in advance, and no matter dismounting is all very convenient, another important benefit is exactly, the roof truss bottom is smooth, and no protruding member need not gap on wallboard when under roof truss partition board being installed, the body of wall flat appearance is attractive in appearance, and can shorten man-hour.
Go up lower chord 1 and 2 among the utility model embodiment and all adopt C80 shaped steel, and web member 3 adopts C50 shaped steel.
