Abstract
The utility model discloses a carbon cloth reinforced wooden beam, which comprises a wooden beam(1) and carbon cloth(2); wherein one or two layers of carbon cloth(2) is affixed on the bottom of the wooden beam(1). The utility model enhances the flexural capacity of the wooden beam via the carbon cloth affixed on the bottom of the wooden beam, thereby resulting in that wooden beams of a timberwork in an ancient architecture can be used continuously without elements replaced, thus value of cultural relics of the ancient architecture is preserved.
Description
Technical field
The utility model relates to a kind of wooden frame, particularly a kind of carbon cloth reinforced wooden frame.
Background technology
Chinese ancient architecture with the timber buildings is main growing up, and is also more with timber buildings in the existing ancient architecture, accounts for more than 50% of whole ancient architectures.Wooden construction has caused worldwide attracting attention with its construction process and remarkable anti-seismic performance cleverly.She is the important component part of the Chinese nation and even world culture, is the valuable cultural heritage that ancestors leave us for, has high history, historical relic, art and scientific value.Therefore must take measures these historic building structures are carried out strengthening by reparative method and protection.
Beam in the historic building structure, a tree, used in making timber for boats, purlin are the main members in the whole timber frame.From the angle of mechanics analysis, belong to flexural member.Because the wood property defective (knot, crackle etc.) of timber self and the influence (rainwater, insect pest etc.) of surrounding environment, add long neglected and in disrepairly, cause these bearing of component to reduce, even crooked splitting occurs, the bottom fractures and be pickled with grains or in wine rotten phenomenon such as fracture.External a lot of ancient wooden bridge, the Qi Qiao purlin also belongs to flexural member.Even and these its bearing capacities of bridge purlin do not reduce, because the increase of top vehicular load also needs to reinforce facing to the Xiu Qiao purlin.But owing to the restriction and the even more important reason of timber resources is in order to protect the value of historical relic self; make that the maintenance and reinforcement of historic building structure can not large-area replacement green wood; simultaneously traditional reinforcing restorative procedure tends to destroy the building original appearance or brings problem such as corrosion; therefore; not having suitable maintenance and reinforcement material and method, is the subject matter that the historic building structure maintenance and reinforcement faces.
And carbon cloth is as a kind of novel reinforced material; obtained extensive use in a lot of fields that comprise space flight; it is introduced in the reinforcing of wooden construction has the advantage that a lot of conventional methods do not have; thereby solved the material and the method problem of historic building structure maintenance and reinforcement, made these extremely important buildings can obtain better protection.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of carbon cloth reinforced wooden frame is provided, and this wooden frame has higher anti-bending bearing capacity, can satisfy the principle of ancient building " restoring the old as the old ", " not changing the building original appearance " simultaneously.
For solving the problems of the technologies described above, the technical scheme of technical solution problem of the present invention is: comprise wooden frame (1), carbon cloth (2), be pasted with carbon cloth (2) in described wooden frame (1) bottom surface.
The number of plies of the carbon cloth (2) that paste described wooden frame (1) bottom surface is 1～2 layer.
Length and the width with wooden frame (1) is identical respectively with width for the length of the carbon cloth (2) that paste described wooden frame (1) bottom surface.
The end of the carbon cloth (2) that paste described wooden frame (1) bottom surface uses the carbon cloth hoop (3) perpendicular to the beam length direction to carry out anchoring.
There are 2～3 carbon cloth hoops (4) at described wooden frame (1) middle part.
The width of described carbon cloth hoop (2,4) is 40～60mm, and length is determined by the wooden frame size, need be left the lap length greater than 100mm.
Spacing between the described carbon cloth hoop (4) is 100～200mm.
Description of drawings
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the profile of Fig. 1.
The specific embodiment
As shown in Figure 1, carbon cloth 2 is sticked on wooden frame 1 bottom surface, use carbon cloth hoop 3 anchorings perpendicular to the beam length direction in this carbon cloth end, there are 2～3 carbon cloth hoops 4 at wooden frame 1 middle part.
In order to reach the purpose that improves the wooden frame anti-bending bearing capacity, the used in amounts of carbon cloth satisfies certain requirement, otherwise will not reach the purpose of reinforcing.Length and the width with wooden frame 1 is identical respectively with width for the length of the carbon cloth 2 that paste wooden frame 1 bottom surface; The width of carbon cloth hoop 3,4 is 40～60mm, and length is determined by the wooden frame size, need be left the lap length greater than 100mm.We are by experimental study, obtained the bearing capacity (seeing Table 1) of unguyed and 1 layer and 2 layers carbon cloth reinforced wooden frame, the result shows that anti-bending bearing capacity improved 15% approximately when the carbon cloth 1 of wooden frame bottom surface was one deck, when carbon cloth 1 was two layers, anti-bending bearing capacity improved 20% approximately.
Unguyed and the carbon cloth reinforced wooden frame bearing capacity ratio of table 1
Carbon cloth improves the construction technology of wooden frame anti-bending bearing capacity:
Taking measures earlier wooden frame is unloaded, afterwards wooden frame is carried out surfacing, then paste the carbon cloth of wooden frame bottom surface, is the carbon cloth hoop then, removes discharge mechanism etc. adhesive glue after doing.The technology that carbon cloth is pasted will meet relevant code requirement.
