Abstract
The utility model relates to a lattice shell construction frame with curve adjustable cylindrical column surface, which is connected by lattice frames. The utility model is characterized in that the lattice frames are provided with fixed nodes and are hinged by an adjusting device; the adjusting device is hinged with the lattice frames through nodes on both ends by a length adjusting rod; an inclined rod is fixedly connected with the lattice frames; the inclined rod is hinged with a horizontal rod through connecting points; the connecting points forms a space quadrangular prism with the length adjusting rod, the horizontal rod and the inclined rod. The utility model has the advantages of simple structure, reasonable structure, equalized stress, convenient assembly and disassembly, low cost and wide adaptability; the curve of the cylindrical column surface lattice shell can be changed at will according to sites and operating requirements.
Description
The utility model relates in the building rack in the steel work, promptly adjustable curvature cylindrical reticulated shell structure.
Its curvature of the cylindrical reticulated shell structure of prior art is changeless, be applicable to permanent construction, can not adapt to provisional frame, particularly put on display, displaying or provisional when movable, the span in needed interim canopy class construction activity house often needs the requirement according to the user, the requirement of function and changing, this just needs to prepare the interim canopy class building of multiple span, thereby causes taking substantial contribution and stack the place.
The purpose of this utility model is: a kind of adjustable curvature cylindrical reticulated shell structure frame is provided, and it is simple in structure, and installation, dismounting, convenient transportation are cheap, can regulate cylindrical reticulated shell curvature arbitrarily according to place size and instructions for use, and its compliance is extensive.
The utility model is achieved in that
A kind of adjustable curvature cylindrical reticulated shell structure frame, form by the rack connection, it is characterized in that: its rack is established fixed-node, hinged by adjusting device, its adjusting device is hinged by two end nodes and rack by the length adjustment bar, and brace and rack are fixedly connected, and brace and horizon bar are hinged by contact, and contact and length adjustment bar, horizon bar, brace constitute the space four bank or ridge.
Elaborate below by embodiment and accompanying drawing:
Fig. 1: the utility model structural representation;
Fig. 2: the utility model A is to structural representation;
Fig. 3: the utility model node 2 structure enlarged diagrams;
Fig. 4: the utility model node 2B is to schematic diagram;
Fig. 5: the utility model node 5 structural representations;
Fig. 6: the utility model node 5C is to structural representation.
Its structure of the utility model is shown in Fig. 1-6: a kind of adjustable curvature cylindrical reticulated shell structure frame, form by rack (1) connection, it is characterized in that: its rack (1) is established fixed-node (17), hinged by adjusting device, its adjusting device is hinged by two end nodes (2) and rack by length adjustment bar (4), and brace (7) is fixedly connected with rack (1), brace (7) is hinged by contact (5) with horizon bar (11), and contact (2), (5) constitute the space four bank or ridge with length adjustment bar (4), horizon bar (11), brace (7).
Its length adjustment bar (4) meshes with the interior nut (6) of adjusting of bar by adjusting screw rod (3), and is fixing through locking nut (5).
Its node (2) is fixedly connected by node seat (8) and four braces (7), is fixed as one by upper boom (16) and rack, and it is hinged by bearing pin (9) and length adjustment bar (4).
Its contact (5) is fixedly connected by outer key seat (56) and horizon bar (11 '), brace (7 '), axial horizon bar (12 '); Key seat (10) is with horizon bar (11), brace (7), axially horizon bar (12) is fixedly connected in it, and outer key seat (56), interior key seat (10) and bearing pin (91) lock by locknut (13) movingly.
The brace (7) of its node (2), upper boom (16), length adjustment bar (4), the axle center of its dried bearing pin of bar center line junction (9), the horizon bar (11 ') of its node (8), (11), brace (7 '), (7), axial horizon bar (12 '), (12), the axle center of its bar center line junction bearing pin (91), the bar center line of its fixed-node (17) intersect at the node ball, the axle among the heart.
The adjustable curvature cylindrical reticulated shell structure frame that the inventor makes is made up of several unit, and the node ball of its node (2), (5), (17), axle are its junction center that connects the rod member center line, and its material is metal, engineering plastics.
Facts have proved: the utility model is simple and reasonable for structure, stress equalization, and the transportation easy installation and removal, cheap, it can change the curvature of cylindrical reticulated shell according to scene and instructions for use arbitrarily, its compliance and extensively.
