The utility model discloses a kind of joist steel upright base in cable testing bridge field, comprise horizontal base plate, substrate fixes through four expansion bolts and body of wall, on substrate, corresponding expansion bolt is respectively arranged with the first connecting hole, two pieces of vertical supporting brackets parallel to each other are symmetrically arranged with on the downside of substrate, the gap that can hold joist steel upright and insert is left between two pieces of supporting brackets, the both sides of supporting bracket are equipped with the side plate perpendicular with supporting bracket, and supporting bracket is provided with second connecting hole that can hold connecting bolt and pass.Four the first connecting holes on substrate are symmetrical arranged between two.First connecting hole and the second connecting hole are mounting hole.In the utility model, the pulling force of joist steel upright acts on joist steel upright base, joist steel upright is avoided directly to contact with body of wall, be subject to the reaction force of body of wall, extend the useful life of joist steel upright, the stabilized structure of joist steel upright base, makes joist steel upright can more stably carrying cable crane span structure.
Description
Technical field
The utility model belongs to cable testing bridge field, is specifically related to a kind of joist steel upright base.
Background technology
Cable testing bridge is divided into the structures such as slot type, pellet type, ladder-type and grid type, is made up of support, trailing arm and installation accessories etc.Building inner cable crane span structure can independently set up, and also can be attached on various building and piping lane support, and be arranged on the outer outdoor crane span structure of building, whole part all needs to carry out zinc-plated process.I-steel is the critical piece of carrying cable crane span structure, is specially adapted to the occasion that cable is many, load heavy, crane span structure span is large, can be mounted to suspension type, vertical type and side arm-type as required.And joist steel upright normally adopts underslung method to be supported on body of wall, in prior art, adopt the welded top fixed head at joist steel upright, with securing member, fixed head is fixedly connected with body of wall, its weak point is: adopt the mode be welded and fixed between fixed head and joist steel upright, and fixed head is the place that stress is concentrated, weld easily ruptures, structural instability.
Utility model content
The purpose of this utility model is to provide a kind of joist steel upright base, can stably support and connection joist steel upright, and make Stability Analysis of Structures, fail safe is better.
The purpose of this utility model is achieved in that a kind of joist steel upright base, comprise horizontal base plate, described substrate fixes through four expansion bolts and body of wall, on substrate, corresponding expansion bolt is respectively arranged with the first connecting hole, two pieces of vertical supporting brackets parallel to each other are symmetrically arranged with on the downside of substrate, the gap that can hold joist steel upright and insert is left between two pieces of supporting brackets, the both sides of described supporting bracket are equipped with the side plate perpendicular with supporting bracket, and described supporting bracket is provided with second connecting hole that can hold connecting bolt and pass.
The utility model in use, first with expansion bolt, substrate and body of wall are fixed, to wait that the web hanging joist steel upright inserts between two pieces of supporting brackets again, make the second connecting hole in supporting bracket corresponding with the installing hole on joist steel upright, connecting bolt is each passed through the installing hole of the second connecting hole, joist steel upright, fixes joist steel upright and supporting bracket.Compared with prior art, the beneficial effects of the utility model are: by being fixedly connected with joist steel upright base by joist steel upright, joist steel upright and body of wall are fixed, the pulling force of whole joist steel upright acts on joist steel upright base, joist steel upright is avoided directly to contact with body of wall, be subject to the reaction force of body of wall, extend the useful life of joist steel upright, the stabilized structure of joist steel upright base, make joist steel upright can more stably carrying cable crane span structure, it is better that the laying of cable testing bridge connects operational security.
As further improvement of the utility model, four the first connecting holes on described substrate are symmetrical arranged between two.By being symmetrical arranged between two by the first connecting hole, substrate can more stably be fixedly connected with body of wall by expansion bolt.
As further improvement of the utility model, described first connecting hole and the second connecting hole are mounting hole.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Fig. 3 is the schematic diagram that the utility model comes into operation.
Fig. 4 is the enlarged drawing at A place in Fig. 3.
Wherein, 1 substrate, 2 expansion bolts, 3 first connecting holes, 4 supporting brackets, 5 side plates, 6 second connecting holes, 7 connecting bolts, 8 joist steel uprights, 9 installing holes, 10 bodies of wall.
Embodiment
As Figure 1-4, for a kind of joist steel upright base, comprise horizontal base plate 1, substrate 1 fixes through four expansion bolts 2 and body of wall 10, on substrate 1, corresponding expansion bolt 2 is respectively arranged with the first connecting hole 3, two pieces of vertical supporting brackets 4 parallel to each other are symmetrically arranged with on the downside of substrate 1, the gap that can hold joist steel upright 8 and insert is left between two pieces of supporting brackets 4, the both sides of supporting bracket 4 are equipped with the side plate 5 perpendicular with supporting bracket 4, and supporting bracket 4 is provided with second connecting hole 6 that can hold connecting bolt 7 and pass.In order to make substrate 1 more firmly be connected with body of wall 10, four the first connecting holes 3 on substrate 1 are symmetrical arranged between two.First connecting hole 3 and the second connecting hole 6 are mounting hole.
During use, first with expansion bolt 2, substrate 1 and body of wall 10 are fixed, to wait that the web hanging joist steel upright 8 inserts between two pieces of supporting brackets 4 again, make the second connecting hole 6 in supporting bracket 4 corresponding with the installing hole 9 on joist steel upright 8, connecting bolt 7 is each passed through the installing hole 9 of the second connecting hole 6, joist steel upright 8, fixes joist steel upright 8 and supporting bracket 4.By joist steel upright 8 is fixedly connected with joist steel upright base, joist steel upright 8 is fixed with body of wall 10, the pulling force of whole joist steel upright 8 acts on joist steel upright base, joist steel upright 8 is avoided directly to contact with body of wall 10, be subject to the reaction force of body of wall 10, extend the useful life of joist steel upright, the stabilized structure of joist steel upright base, make joist steel upright can more stably carrying cable crane span structure, it is better that the laying of cable testing bridge connects operational security.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection range of the present utility model.
