Description
Technical field
The utility model relates to a kind of combined member bar.More specifically, a kind of combined member bar of changeable function is related to.
Background technology
Current, the support in engineering is common in the temporary structure in construction with colony's column form, and the construction bracket that China commonly uses has fastener type, gate-type, bowl fastening type, button disc type (the sub-support of thunder), dish button etc.But in now all cantilever type, all could not resolve the inclined member connectivity problem of overturning or slip resistance analysis, what have does not even simply just establish brace, and take to beat bridging method with extra rotary buckle and steel pipe and solve overturning or slip resistance analysis problem, but add the work of bridging in length and breadth separately, make the assembling of support become very complicated.
The plane that truss is made up of straight-bar triangle or space structures, under gravity, truss member mainly bears axial tension or pressure, thus takes full advantage of the intensity of material, reach the object alleviating deadweight and increase rigidity, be therefore widely used in the load-carrying members compared with large span.The node of truss generally adopts the rigid joint of welding, and the truss welded is very heavy, and transport, installation must use corresponding facility.Even if the assembling of Bailey truss is also like this.
Rack be by many rod members by certain grid configuration, by node, rod member is connected to space structures.Rack has the advantages such as space performance is good, lightweight, rigidity is large, anti-seismic performance is good.The shortcoming of rack is that to intersect at the rod member of same node numerous, and the making of node, the connection of rod member and node is all very complicated.Grid node type mainly contains three kinds, i.e. bolted spherical node, welded spherical node, Welded Plate joint.The requirement on machining accuracy of bolted spherical node is higher, and need arrange the angle of rod member, otherwise bolt sphere will be increased, and overweight bolt sphere is installed very difficult.Welded spherical node is welding fabrication at the construction field (site), and therefore, welder level, welding surroundings shaping to rod member blanking, spherical shell all have higher requirements, otherwise difficult quality guarantee.Welded Plate joint welding requirements with solder sphere rack, but will consider the Influence from Eccentric such as shaped steel, weld seam.
At existing engineering medium-height trestle, rack, truss with respective performance applications at different aspect, be generally according to the stressed least favorable Load Combination of engineering, select according to the operating characteristic of support, rack and truss.And according to the stressed change of engineering, support, rack and truss cannot be used flexibly, this will increase engineering construction cost greatly.
Utility model content
For the defect that above-mentioned prior art exists, technical problem to be solved by this invention is, a kind of novel compositions rod member of convertible support body function is provided, it can form separately support, rack, truss, again can according to the support body characteristic of support, rack, truss three, according to stressed change in same engineering, the support body type of seamless transitions support, rack, truss, thus given full play to the features of support, rack, truss.And overcome the ubiquitous inclined member of support and connect a difficult problem, difficulty is installed in the transport solving truss, created rack without node part assembled formation, avoid the bolt operation of rapid wear, eliminate the loose mail smallclothes of easily loss.
For solving the problems of the technologies described above, the utility model adopts following technical proposals:
A kind of combined member bar of changeable function, this combined member bar is cube structure, comprise cross bar, the first montant, oblique rod, diagonally opposing corner bar, cross latch, described oblique rod is separately positioned on four facades of cube structure, and described diagonally opposing corner bar is arranged along the diagonal of cube structure; Described cross bar is positioned at end face and the bottom surface of support body unit, and described first montant is positioned at the facade of support body unit, described cross latch and described first montant grafting, and cross bar is fixed on bottom and the top layer of cube structure;
Described cross bar comprises cross-bar body and L-type connector, one end of described L-type connector is connected with an end of cross-bar body, and the other end is cross plug, and described cross plug is provided with locked groove and inclined-plane, the corner of described L-type junction plate is provided with circular hole, and is provided with faulting of slab ends at described circular hole place; The other end of described cross-bar body is provided with the cross bar lock dog matched with locked groove, and described cross bar lock dog is connected with cross-bar body by cross bar lock dog spring leaf, and embeds in cross-bar body;
Described cross latch is made up of base and cross plug, and the diameter of described base is greater than the Circularhole diameter on L-type junction plate;
The both ends of described first montant are equipped with montant lock dog, and the montant lock dog of described first montant and the locked groove of cross latch match, and described montant lock dog is connected with montant body by montant lock dog spring leaf, and embeds in the first montant;
The upper and lower end of described first montant is equipped with the brace cross plug connecting described oblique rod and diagonally opposing corner bar, the both ends of described oblique rod, diagonally opposing corner bar are respectively equipped with the oblique rod lock dog and diagonally opposing corner lock dog that mate with brace cross plug, described oblique rod lock dog is connected with oblique rod by oblique rod lock dog spring leaf, and embed in oblique rod, described diagonally opposing corner lever lock block is connected with diagonally opposing corner bar by diagonally opposing corner lever lock block spring leaf, and embed in diagonally opposing corner bar, described oblique rod lock dog and diagonally opposing corner lever lock block respectively with the grafting of brace cross plug.
Preferably, this combined member bar also comprises the second montant, and described second montant comprises montant body and cross plug, and one end of described montant body is connected with cross plug, is provided with described montant lock dog near the other end of described montant body; The upper and lower end of described montant body is equipped with the brace cross plug connecting described oblique rod and diagonally opposing corner bar.
The beneficial effects of the utility model are as follows:
The present invention makes simply compared with existing support, rack, truss, and processing and fabricating technical threshold is low, therefore significantly can reduce cost.And it can form separately support, rack or truss, also in use according to engineering stressing conditions seamless transitions support, form between rack and truss three, thus the respective characteristic of support, rack, truss can be given full play to.And overcome the ubiquitous inclined member of support and connect a difficult problem, difficulty is installed in the transport solving truss, created rack without node part assembled formation, avoid the bolt operation of rapid wear, eliminate the loose mail smallclothes of easily loss.The present invention not only possesses the repertoire of support, rack, truss three kinds of technical schemes, eliminate again the defect of three, create simultaneously one according to stressing conditions can seamless transitions support, rack, trass-spar type structure, be therefore a kind of combined member bar of novelty.
