Abstract
The utility model discloses a connection structure of a roofing upper lever in acid corrosive environment, which comprises a mansard reinforced concrete roof truss (1) and two or more supporting rods (2), wherein a roofing upper lever (3) is arranged below the mansard reinforced concrete roof truss (1), and the position of the reinforced concrete roof truss (1) on which the roofing upper lever (3) is arranged is connected with two main connection gusset plates (4), and each main connection gusset plate (4) is connected with one or two supporting rods (2), and besides the supporting rods (2) which is connected with the main connection gusset plates (4), the rest supporting rods (2) are connected with the main connection gusset plates (4) through a connection gusset plate (5). The connection structure can solve the problems of the prior art such as difficult installation, time wasting, non-economical and the like caused by adopting a single connection gusset plate; the roofing upper lever and the supporting rods adopt a steel tube supporting component, thus ensuring the completeness of the joints of the components and the corrosion prevention requirements of the components.
Description
Technical field:
The utility model patent relate to a kind of under the sour corrosion environment syndeton of roofing horizontal support, belong to the roof support structure technical field of construction.
Technical background:
In the structure design of titanium industrial premises, because the product of being produced can produce the medium of sour corrosion in process of production, as gases such as hydrogen chloride, chlorine.According to the requirement of industrial construction anti-corrosion code, should not adopt existing roofing horizontal support structure, promptly can not adopt the angle steel by welding back-to-back is primary structure member.For satisfying the sour corrosion environment, now steel pipes that adopt are replaced the existing angle steel of welding back-to-back more, but because support bar is aerial work with being connected of broken line shape steel concrete roof truss, adopt existing direct welding manner to connect the support bar of tubulose, then have shortcomings such as on-the-spot splicing installation is difficult, uneconomical, unreasonable, long construction period.
The content of invention:
The technical problems to be solved in the utility model provide a kind of construct simple, save the short syndeton of roofing horizontal support under the sour corrosion environment of construction costs, construction period, can overcome the deficiencies in the prior art.
The technical solution of the utility model: it comprises broken line shape steel concrete roof truss, support bar more than two or two, be arranged with the roofing horizontal support at broken line shape steel concrete roof truss, be connected with two blocks of main connected node plates at the reinforced concrete roof truss place that is provided with roofing horizontal support position, on every block of main connected node plate, be connected with 1 or 2 support bars, the support bar on being connected main connected node plate, all the other support bars are connected with main connected node plate by time connected node plate.
The roofing horizontal support is the steel pipe supporting member.
The support bar steel tube component.
Offer bayonet slot at support bar with the position that main connected node plate or inferior connected node plate are connected, bayonet slot is connected on main connected node plate or the inferior connected node plate.
Be connected with the thick steel plate of 6～8mm in the support bar end.
Be connected with angle steel on broken line shape steel concrete roof truss, main connected node plate is connected on the angle steel.
Support bar is that first bolt is connected welding again with main connected node plate or inferior connected node plate connected mode.
Compared with prior art, the utility model is by being connected with two blocks of main connected node plates at the steel concrete roof truss place that is provided with roofing horizontal support position, on every block of main connected node plate, be connected with 1 or 2 support bars, the support bar on being connected main connected node plate, all the other support bars are connected with main connected node plate by time connected node plate.Such syndeton can be connected with main connected node plate a support bar earlier when construction on ground, connect the back lifting, second support bar aloft connects, when connecting the 3rd support bar, can on the 3rd support bar, connect one time the connected node plate earlier, be connected with main connected node plate by inferior connected node plate, so just can avoid installation difficulty that the single connected node strip of available technology adopting comes, time-consuming problem such as uneconomical; The support bar of roofing horizontal support adopts the steel pipe supporting member, can guarantee the integrality of component node and the requirement for anticorrosion of member like this.Offer bayonet slot with main connected node plate with the position that time connected node plate is connected at support bar, bayonet slot is connected on main connected node plate and time connected node plate; This connected mode can make syndeton of the present utility model more stable; Be connected with the thick steel plate of 6～8mm in the support bar end, can further improve anti-corrosive properties of the present utility model like this.Be connected with angle steel on broken line shape steel concrete roof truss, main connected node plate is connected on the angle steel, and such design can make installation oversimplify more; The utility model also can be saved construction investment in a large number, reduces construction volume, shorten the duration of a project simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment: as shown in Figure 1, for the strong of acid medium effect arranged, the workshop of middle corrosion class, adopt broken line shape steel concrete roof truss 1, with tubular supporting bar 2, be arranged with roofing horizontal support 3 at broken line shape steel concrete roof truss 1, roofing horizontal support 3 is the steel pipe supporting member, on ground main connected node plate 4 is welded on earlier on first support bar 2, then first support bar 2 is lifted on the reinforced concrete roof truss 1 that is provided with roofing horizontal support 3 positions, on broken line shape steel concrete roof truss 1, be connected with angle steel 6, main connected node plate 4 is bearing on the angle steel 6, fixes with erection bolt; When support bar 2 is connected with time connected node plate 5 with main connected node plate 4, offer a bayonet slot earlier in the end of support bar 2, then bayonet slot is connected on main connected node plate 4 and time connected node plate 5, clamping back is well welded with the bolt connection earlier again; After fixing main connected node plate 4, second support bar 2 also is connected on the main connected node plate 4, connected mode is identical with first support bar; On being connected main connected node plate 4 first, second support bar 2, the connected mode of remaining support bar is, on all the other support bars 2, connect time connected node plate 5 earlier, to be connected with the support bar lifting of time connected node plate 5 then, inferior connected node plate 5 is bearing on the main connected node plate 4, welding again after with erection bolt main connected node plate 4 and time connected node plate 5 being fixed; After connecting support bar 2, the thick steel plate of welding 6～8mm carries out shutoff with the steel pipe mouth in support bar 2 ends, can improve antiacid rotten performance like this.
