Abstract
The utility model discloses a reinforcing device for a timberwork girder or column. The reinforcing device for the timberwork girder or column comprises a plurality of steel belt hoops fastened around the timberwork girder or the timberwork column. Tensile stress of the steel belt hoops is from 60 percent to 80 percent of ultimate tensile strength of a steel belt. According to the device, large transverse restrain prestress to the timberwork girder or the timber work column is produced by baling of steel belt hooks, and therefore the girder and the column receives good initiative transverse restrain to a certain extent. Strength and deformability of the timberwork girder or the timberwork column are improved effectively and cracking of the timberwork girder or the timberwork column can be limited or delayed effectively. The device has the advantages of being convenient to construct, easy to operate, low in cost and high in performance.
Description
Technical field
The utility model relates to the building unit reinforcing technique, is specifically related to the bracing means of a kind of wooden construction beam or wooden construction post.
Background technology
Wooden construction occupies very consequence under construction as a kind of important form of structure, and particularly in Chinese ancient architecture, its deal more very.Domestic existing a large amount of wooden construction in ancient times, these all are the legacy of historys of our preciousness.
Because of the remote past, the destructions in various degree such as damaging by worms appears in a large amount of wooden construction beam, posts, cracking are needed repairerment badly.Reinforcement means commonly used mainly contains the steel plate leash law and pastes the carbon cloth method at present.The binding effect of its light plate leash law is relatively poor, and steel using amount is more, and difficulty of construction is larger; For pasting the carbon cloth method, only have competence exertion effect after the deformation of member arrives to a certain degree, and consolidation effect is not ideal enough.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of point of application is even, overall structure is stable wooden construction beam or the bracing means of post.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
The bracing means of wooden construction beam of the present utility model or post comprises the multiple tracks steel strap that is anchored on wooden construction beam or the wooden construction post whole body, the tension stress of described steel strap be steel band ultimate tensile strength 60%～80%.
Described steel strap is provided with the fastener for bundling articles with pneumatic Machine for packing steel band sealing, and the fastener for bundling articles on the adjacent steel strap is positioned at the not ipsilateral of wooden construction beam or wooden construction post.
Described steel strap material is blue steel strip, stainless steel band or aluminum alloy strip.
Tensile strength 〉=the 800MPa of described steel strap, the thickness of strips of steel strap are 0.5～1.5mm, and the width of steel band of steel strap is 30～100mm.
Bracing means of the present utility model relies on the packing steel strap that wooden construction beam or post are produced larger horizontal restrain prestressing force, make in beam, the post existing part be subject to good active lateral constraint, can effectively improve intensity and the deformability of beam, post, and effectively limit or delay and ftracture, and this device has easy construction, simple to operate, with low cost, the characteristics of function admirable.

Fig. 2 is the bracing means schematic diagram of the utility model wooden construction post.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
The specific embodiment
Embodiment 1:
As shown in Figure 1, follow the technical solution of the utility model, wooden construction beam 1 bracing means that this embodiment provides comprises along the beam length direction and laterally is anchored on wooden frame multiple tracks steel strap 2 with it, the tension stress of described steel strap 2 be steel band ultimate tensile strength 60%.Steel strap 2 wherein is provided with the fastener for bundling articles 3 with pneumatic Machine for packing steel band sealing, fastener for bundling articles 3 on the adjacent twice steel strap is positioned at the not ipsilateral of wooden frame, and steel strap 2 materials are blue steel strip, and the intensity of steel strap 2 is 900MPa, thickness is 1.0mm, and width is 100mm.
Before wooden frame 1 is reinforced, carry out first removing surface, then with steel strap 2 along wooden frame 1 circumferential closure, utilize pneumatic packaging machine that steel strap 2 packings are installed, fixing with fastener for bundling articles 3 permanent sealings, fastener for bundling articles 3 on the adjacent twice steel strap 2 is positioned at the not ipsilateral of wooden frame, spacing between the adjacent twice steel strap 2 is 300mm at beam-ends, span centre is 500mm, when packing was installed, it was 60% of steel band ultimate tensile strength that the packing elasticity of adjusting given atmospheric pressure value control steel strap 2 makes the steel band tension stress.
Embodiment 2:
As shown in Figure 2, follow the technical solution of the utility model, wooden construction post 1 bracing means that this embodiment provides comprises along the post short transverse and laterally is anchored on pin multiple tracks steel strap 2 with it, the tension stress of described steel strap 2 be steel band ultimate tensile strength 70%.Steel strap 2 wherein is provided with the fastener for bundling articles 3 with pneumatic Machine for packing steel band sealing, fastener for bundling articles 3 on the adjacent twice steel strap is positioned at the not ipsilateral of pin, and steel strap 2 materials are blue steel strip, and the intensity of steel strap 2 is 1000MPa, thickness is 1.0mm, and width is 80mm.
Before pin 1 is reinforced, carry out first removing surface, then with steel strap 2 along pin 1 circumferential closure, utilize pneumatic packaging machine that steel strap 2 packings are installed, fixing with fastener for bundling articles 3 permanent sealings, fastener for bundling articles 3 on the adjacent twice steel strap 2 is positioned at the not ipsilateral of pin, spacing between the adjacent twice steel strap 2 is 300mm at styletable, the middle part is 600mm, when packing was installed, it was 70% of steel band ultimate tensile strength that the packing elasticity of adjusting given atmospheric pressure value control steel strap 2 makes the steel band tension stress.
The utility model improves beyond the intensity realize increasing force-summing element (Covered with Angles strap) by pneumatic packaging technique, most important part is to rely on the packing steel strap that timber in the member is produced very large horizontal restrain prestressing force, make in institute's strenthening member existing material be subject to good active lateral constraint, can effectively improve the strength and deformation ability of the member that is tied, and effectively limit or delay the cracking of member, thereby greatly improve institute's strenthening member deformation performance and energy dissipation capacity, belong to initiatively reinforcing technique category, can improve comprehensively and reinforce rear component strength, distortion, the property indices such as power consumption and anti-seismic performance.
