Abstract
The utility model discloses a kind of prestress steel clark beam, including steel and wood composite beam main body, presstressed reinforcing steel, anchorage, anchor plate, tapping screw, bolt or structure adhesive.The steel and wood composite beam main body is the combination of shaped steel and wood materials, is glued using metal connecting piece connection or adhesive.The presstressed reinforcing steel both ends are anchored at beam-ends by anchorage and anchor plate, and combination beam main body is reinforced with anchor plate contact position using tapping screw.Component described in this patent can give full play to wood materials and the respective superior function of steel, improve the bearing capacity and stiffness of beam, reduce creep, reduce the area of section of large span timber structure beam, while have the naturally comfortable outward appearance of wood materials.In addition the simple process, factory prefabricating production can be achieved, there is higher feasibility.
Description
Technical field：
A kind of prestress steel clark beam is the utility model is related to, is mainly used in timber engineering technical field.
Background technology：
In modern wood structure system, wooden frame by it is curved when brittle break typically occurs at the defective place of tension side, timber resists
Pressure performance is not fully utilized.Steel strength is high, tension or can both be pressurized, but easily overall collapse or local buckling occur
Phenomenon, unstability causes the geometry of component or structure to undergo mutation and completely loses bearing capacity.And the group of steel wood component
Close collaboration and easily form rationally efficient new structural form, the superior function of timber resistance to compression and steel tension can be given full play to, had
The shortcomings that bearing capacity reduces caused by effect avoids steel local buckling.
At present, there are certain research, Ke Yiti in terms of strengthening using reinforcing bar or steel wire for wooden frame both at home and abroad
The bearing capacity of high wooden frame, but can not effectively reduce the mid-span deflection of wooden frame.Across in timber structure, having passing through both at home and abroad greatly
To the example to the external prestressed reinforcement of tensioning of wooden frame or steel strand wires, timber can be greatly lowered because position caused by creep
Move, deformation of member ability and ultimate bearing capacity can be significantly improved, but the problem of reinforcing bar or chain mark be present, break and change
Timber structural system naturally comfortable Wood environment and visual experience.
Utility model content：
The utility model proposes a kind of prestress steel clark beam, and its object is to overcome the deficiencies in the prior art, leads to
Introducing prestressing technique is crossed, with reference to shaped steel and the respective advantageous characteristic of wooden engineering material, improves the bearing capacity and just of beam
Degree, creep is reduced, reduce the area of section of large span timber structure beam, while there is the naturally comfortable outward appearance of wood materials.In addition
The simple process, factory prefabricating production can be achieved.
The technical solution adopted in the utility model is：A kind of prestress steel clark beam, including：Steel and wood composite beam main body,
Presstressed reinforcing steel, anchorage, anchor plate, tapping screw, bolt or structure adhesive.The steel and wood composite beam main body is shaped steel and wood
The combination of material, it is glued using connector connection or adhesive.The deformed bar both ends pass through anchorage and anchor plate anchor
Gu in beam-ends, combination beam main body is provided with the tapping screw of enhancing with anchor plate contact position.
The steel and wood composite beam main body is that shaped steel and wood materials combine, and shaped steel is I-shaped, H profile steel, cold-formed thin-walled C steel
One kind.Wood materials are sawn timber, integrated timber, laminated veneer lumber, one kind of parallel strand laminated wood.
It is described the web of two C-type steels mutually to be leaned on using during cold-formed thin-walled C steel, connected by connector or adhesive
Connect, form the I-shaped section shaped steel for thickening web.
The steel and wood composite beam main body wood materials are connected on shaped steel at lower flange, and consistent with shaped steel length.
The shaped steel of the steel and wood composite beam main body can be connected with wood materials by metal connecting piece, it is possible to use adhesive
It is glued.
The presstressed reinforcing steel is one kind in steel strand wires, screw-thread steel, steel wire rope.
The anchorage is steel strand wires, steel wire rope, screw-thread steel or reinforcing pull rod anchorage.
Compared with prior art, having the beneficial effect that acquired by the utility model：
By wooden engineering material and shaped steel combination, the superior function of timber resistance to compression and steel tension is given full play to, avoids wood
The shortcomings that bearing capacity caused by brittle break and steel local buckling occur for material tensile capacity deficiency reduces.Introduce prestressing force skill
Art, the deformation of beam can be effectively reduced, improve the long term structural performance of component.It can be applied in large span timber structure, there is provided good
Good bearing capacity, reduce beam section area, save material.It is simultaneously easy to process, prefabrication can be achieved.
