Description
Technical field
The invention provides a kind of string wood arch structure and manufacture method thereof, belong to timber structural techniques field.
Background technology
Laminated wood is take log as main raw material(s), adopts high-performance environmentally-friendly type bonding adhesive, the composite wood that utilizes modern timber process technology to make.Owing to having, energy-conserving and environment-protective, structural performance are good, size shape is not subject to the advantages such as former size class restriction, and as far back as last century four, the fifties, the development of qlue timber structurer has spreaded all over the state such as America and Europe, Japan, in a large number for greatly across, space and bridge construction.The bending failure form of tradition gummed wood arch is mostly the stress destruction being caused by tight side defect, and strength of wood especially compressive strength can not be fully used.And wood arch, conventionally because meeting the beam section that deformation requirements needs are larger, causes the strength of materials not make full use of and wastes timber in large span wooden construction.
Beam string structure is suggested at first as being a kind of " with the pressurized strut connection self equilibrium systems that bending component and lower edge tensional element form that winds up ".The bending component that winds up generally adopts domes, lower edge tensional element adopts high strength drag-line, this combination has been given full play to the stress performance of arch form structure and has been taken full advantage of the tensile strength of rope, thereby improved the stress performance of total system, the integral rigidity of a beam string structure is mainly subject to affect from bending resistance component cross section with two aspects of geometrical body that drag-line forms.
At present, open beam string structure and be mainly used in field of steel structure.Employing steel strut connects a beam string structure of wind up girder steel and the formation of lower edge drag-line, and successful Application, in all kinds of long-span space structural steelworks, has obtained good architectural effect and economic benefit.And only rest at present conceptual phase for a string wood arch, and rare engineering application, engineering application rests on straight beam, does not occur wood arch, differs larger with the form of a beam string structure.Simultaneously being connected structure and strut and constructing the requirement that how to meet a beam string structure being connected of wood arch and rarely have and relate to of wood arch end and drag-line.
Summary of the invention
Technical problem to be solved by this invention is the deficiency existing for prior art, and provide one to open string wood arch structure and preparation method, can under the prerequisite that does not strengthen wood arch depth of section, effectively improve wood arch integral rigidity, save timber, transport, construct and be simple and convenient, and can significantly effectively improve wood arch bearing capacity.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
An a kind of string wood arch structure, is characterized in that: comprise a gummed wood arch, a prestressed cable, many struts; Be provided with the first connector at the two ends of described gummed wood arch, be provided with second connector identical with described strut number at the lower end edge length direction of described gummed wood arch; The first described connector be two by the steel fill plate of bolton, the second described connector is a junction plate with two journal stirrups, on described journal stirrup, is provided with pin-and-hole; Be provided with the 3rd connector in the upper end of described strut, be provided with the 4th connector in the lower end of described strut, the 3rd described connector comprises a head plate, on this head plate, be also provided with two journal stirrups, the 4th described connector also comprises a head plate, has been bolted a pressing plate on this head plate; Described drag-line two ends are connected with described gummed wood arch two ends by described steel fill plate; The upper end of described strut is connected with the lower end of gummed wood arch by a bolt that is plugged on head plate upper journal and junction plate upper journal; Described drag-line is fastened between the head plate and pressing plate of strut lower end.
Strut of the present invention upper end and wood arch junction are provided with connector, and every strut lower end and drag-line junction are also provided with connector.The connector of strut upper end and wood arch improves the plain radial bearing in Machine Design, this kind of connected mode can be born axial load and less plane external load, and strut can guarantee freely to rotate in model plane, so this node can be seen hinged joint in desirable face as.The connector of strut and drag-line is to adopt two blocks of steel clamp plates that drag-line is fixed, clamped, and clamping plate upper end and strut welding, and open a conduit in the middle of two block plates, and arcwall face is set in drag-line exit prevents from that drag-line from bending after stressed to cut off.
Concrete installation steps are:
1) offer conduit at wood arch two ends and wait until installation steel fill plate, conduit is pressed the setting-out of steel fill plate shape, at steel fill plate and wood arch end correspondence position auger shell keyhole, and cleaning hole road wood chip after boring;
2) junction plate of each strut and wood arch connector is close to wood arch design surface, strut positions place, cleaning hole road wood chip after the boring of junction plate periphery, installation connecting element with bolts;
3) adopt the mode of weld all around to be welded in strut and wood arch connector bottom bulkhead plate strut upper end, same strut lower end adopts the mode of weld all around and the welding of the connector of strut and rope, the center-aligned of should trying one's best when weld all around;
4) be bolted mode at wood arch both ends steel fill plate is installed, drag-line is connected with steel fill plate by cord clip, and bolt hole position welding steel is reinforced.
5) drag-line is finally connected to wood arch other end steel fill plate by the connector of each strut and rope successively from wood arch one end steel fill plate successively.
6) to start one end be stretching end to drag-line, and the other end is fixed end.When stretch-draw, by tightening/loosen nut to adjust drag-line prestressing force, reach stretching control force stretch-draw and complete.
Compared with prior art, the advantage that the present invention has is: a kind of string wood arch preparation method is provided, can under the prerequisite that does not strengthen wood arch depth of section, effectively improves wood arch integral rigidity, save timber, transport, construct and be simple and convenient, and can significantly effectively improve wood arch bearing capacity.
