Description

Technical Field

[0001] This invention relates to the field of reinforcement technology for window spans in masonry structures, and in particular to a reinforcement structure and method for cross-bonding carbon fiber cloth on the inner side of a window span. Background Technology

[0002] In masonry structures, the spandrel wall is a primary vertical support component used to support the superstructure. Due to the openings in the wall, it becomes a weak point in the structure under horizontal forces such as earthquakes, easily suffering earthquake damage that can lead to X-shaped intersecting cracks or even partial collapse, resulting in overall structural failure. To enhance the load-bearing capacity of the spandrel wall, the masonry structure is often reinforced as a whole, such as by using a reinforced concrete mesh surface layer or shotcrete. These reinforcement methods are effective, but they can easily damage the cultural relics and historical buildings, causing irreversible damage. Therefore, the use of these conventional solutions in the reinforcement of cultural relics and historical buildings is often not permitted.

[0003] Therefore, there is an urgent need for a reinforcement structure and method for cross-bonding carbon fiber cloth on the inner side of the window sill wall, which can effectively improve the horizontal bearing capacity of the structure, the seismic performance of the structure, and the overall stability and safety, while avoiding damage to the cultural relics and the building facade. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following solution:

[0006] This invention provides a cross-bonded carbon fiber cloth reinforcement structure for the inner side of a window sill, comprising: a window sill body, a cleanroom layer, cross-bonded carbon fiber cloth layers, a first adhesive layer, and a restraint layer. The window sill body is disposed between two windows on a wall. The cleanroom layer is formed by cleaning, repairing, and leveling the inner and outer sides of the window sill body. The cross-bonded carbon fiber cloth layers include a first carbon fiber cloth and a second carbon fiber cloth. The first carbon fiber cloth layer is disposed along one diagonal of the inner side of the window sill body and extends upward and downward beyond the window sill body. The second carbon fiber cloth layer is disposed along the other diagonal of the inner side of the window sill body. The window wall body is set at an angle and extends upward and downward. The first carbon fiber cloth and the second carbon fiber cloth are arranged crosswise. The first adhesive layer is used to be disposed between the cross carbon fiber cloth layer and the window wall body to bond and fix the cross carbon fiber cloth layer to the window wall body. The constraint layer is used to be horizontally disposed on the side of the cross carbon fiber cloth layer away from the window wall body to constrain the cross carbon fiber cloth layer. The constraint layer is fixedly connected to the window wall body, and the two ends of the constraint layer extend to both sides of the window wall body and are fixedly connected to both sides of the window wall body.

[0007] Preferably, the constraint layer includes a third carbon fiber cloth and a fourth carbon fiber cloth. The third carbon fiber cloth is fixedly disposed on the top of the window spandrel wall body and on the side of the intersecting carbon fiber cloth layer away from the window spandrel wall body. The third carbon fiber cloth is fixedly connected to the window spandrel wall body, and both ends of the third carbon fiber cloth extend to both sides of the window spandrel wall body and are fixedly connected to both sides of the window spandrel wall body. The fourth carbon fiber cloth is fixedly disposed on the bottom of the window spandrel wall body and on the side of the intersecting carbon fiber cloth layer away from the window spandrel wall body. The fourth carbon fiber cloth is fixedly connected to the window spandrel wall body, and both ends of the fourth carbon fiber cloth extend to both sides of the window spandrel wall body and are fixedly connected to both sides of the window spandrel wall body.

[0008] Preferably, the constraint layer further includes a second adhesive layer, which is adhesively disposed on the side of the constraint layer near the window wall body, and the second adhesive layer is bonded and fixed to the window wall body.

[0009] Preferably, the width of the third carbon fiber cloth is 100~200mm, and the width of the fourth carbon fiber cloth is the same as that of the third carbon fiber cloth.

[0010] Preferably, the width of the second adhesive layer is the same as the width of the constraint layer, and the second adhesive layer is formed by uniformly applying structural adhesive.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The purpose of this invention is to provide a cross-bonded carbon fiber cloth reinforcement structure and method for the inner side of the window sill wall, so as to solve the problems existing in the prior art, avoid damage to the cultural relics and the building facade, effectively improve the horizontal bearing capacity of the structure, effectively improve the seismic performance of the structure, and effectively improve the overall stability and safety.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0027] This invention provides a cross-bonded carbon fiber cloth reinforcement structure for the inner side of a window sill wall, such as... Figures 1-2As shown, the structure includes: a window sill body, a cleanroom layer, a cross-linked carbon fiber cloth layer, a first adhesive layer, and a restraining layer. The window sill body is disposed between two windows on a wall. The cleanroom layer is formed by cleaning, repairing, and leveling the inner and outer sides of the window sill body. The cross-linked carbon fiber cloth layer includes a first carbon fiber cloth and a second carbon fiber cloth. The first carbon fiber cloth layer is disposed along one diagonal of the inner side of the window sill body and extends upward and downward beyond the window sill body. The second carbon fiber cloth is disposed along another diagonal of the inner side of the window sill body and extends upward and downward beyond the window sill body. The first carbon fiber cloth and the second carbon fiber cloth are arranged cross-linkedly. The first adhesive layer is disposed between the cross-linked carbon fiber cloth layer and the window sill body to bond and fix the cross-linked carbon fiber cloth layer to the window sill body. The restraining layer is horizontally disposed away from the cross-linked carbon fiber cloth layer. One side of the body is used to constrain the cross-carbon fiber cloth layer. The constraining layer is fixedly connected to the main body of the window spandrel wall, and both ends of the constraining layer extend to both sides of the main body of the window spandrel wall and are fixedly connected to both sides of the main body of the window spandrel wall. By setting the cross-carbon fiber cloth layer and bonding it to the main body of the window spandrel wall through the first adhesive layer, the force direction of the carbon fiber cloth is basically the same as the horizontal force direction, which enhances the horizontal bearing capacity of the window spandrel wall, avoids the formation of X-shaped cracks in the window spandrel wall under earthquake action, reduces the risk of local wall collapse, and greatly improves the horizontal bearing capacity of the structure due to the addition of cross-carbon fiber cloth, improves the seismic performance of the structure, and improves the overall stability and safety. In addition, by setting a clean layer, the bonding effect between the first adhesive layer and the main body of the window spandrel wall is effectively guaranteed. By setting a constraining layer to further constrain the cross-carbon fiber cloth layer, the stability of the connection between the cross-carbon fiber cloth layer and the main body of the window spandrel wall is guaranteed.

[0028] In a preferred embodiment, the constraint layer includes a third carbon fiber cloth and a fourth carbon fiber cloth. The third carbon fiber cloth is fixedly disposed on the top of the window spandrel wall body and on the side of the intersecting carbon fiber cloth layer away from the window spandrel wall body. The third carbon fiber cloth is fixedly connected to the window spandrel wall body, and its two ends extend to both sides of the window spandrel wall body and are fixedly connected to both sides of the window spandrel wall body. The fourth carbon fiber cloth is fixedly disposed on the bottom of the window spandrel wall body and on the side of the intersecting carbon fiber cloth layer away from the window spandrel wall body. The fourth carbon fiber cloth is fixedly connected to the window spandrel wall body, and its two ends extend to both sides of the window spandrel wall body and are fixedly connected to both sides of the window spandrel wall body. By constraining the top of the intersecting carbon fiber cloth layer with the third carbon fiber cloth and constraining the bottom of the intersecting carbon fiber cloth layer with the fourth carbon fiber cloth, the connection between the intersecting carbon fiber cloth layer and the window spandrel wall body can be strengthened, ensuring that the carbon fiber cloth of the intersecting carbon fiber cloth layer and the window spandrel wall body together bear the force in the horizontal direction.

[0029] In a preferred embodiment, the constraint layer further includes a second adhesive layer, which is bonded to the side of the constraint layer near the window wall body. The second adhesive layer is bonded and fixed to the window wall body. This bonding and fixing method is simple in structure, convenient in construction, and can avoid structural damage to the window wall body.

[0030] In a preferred embodiment, the width of the third carbon fiber cloth is 100-200mm, and the width of the fourth carbon fiber cloth is the same as that of the third carbon fiber cloth. Preferably, both the third and fourth carbon fiber cloths are 100mm wide.

[0031] In a preferred embodiment of this invention, the width of the second adhesive layer is the same as the width of the constraint layer. The second adhesive layer is formed by uniformly applying structural adhesive, which is readily available and can be firmly bonded to the window sill body. Making the width of the second adhesive layer the same as the width of the constraint layer ensures that the constraint layer is firmly bonded.

[0032] In a preferred embodiment, the width of the first carbon fiber cloth is 150~200mm, preferably 200mm, and the width of the first carbon fiber cloth is the same as the width of the second carbon fiber cloth.

[0033] In a preferred embodiment, the width of the first adhesive layer is the same as the width of the cross-carbon fiber cloth layer, and the first adhesive layer is formed by uniformly applying structural adhesive. Structural adhesive is readily available and can be firmly bonded to the window sill body. Making the width of the first adhesive layer the same as the width of the constraint layer can firmly bond the cross-carbon fiber cloth layer. Example 2

[0034] This embodiment also provides a reinforcement method for a cross-bonded carbon fiber cloth reinforcement structure on the inner side of a window sill wall, as in Embodiment 1, including the following steps:

[0035] S1: Clean, repair, level, and remove stains from the inner and outer sides of the window wall body;

[0036] S2: Apply structural adhesive to the fixed position of the cross carbon fiber cloth layer on the window wall body to form the first adhesive layer;

[0037] S3: The first carbon fiber cloth is set along one diagonal of the inner side of the window wall body and extends upward and downward out of the window wall body and is bonded and fixed to the first adhesive layer. The second carbon fiber cloth is set along the other diagonal of the inner side of the window wall body and extends upward and downward out of the window wall body and is bonded and fixed to the first adhesive layer.

[0038] Apply structural adhesive evenly to the top and bottom of the window sill wall to form a second bonding layer;

[0039] S4: Bond and fix the third carbon fiber cloth to the second adhesive layer at the top of the window wall body, and extend both ends of the third carbon fiber cloth to both sides of the window wall body and bond and fix them to both sides of the window wall body. Bond and fix the fourth carbon fiber cloth to the second adhesive layer at the bottom of the window wall body, and extend both ends of the fourth carbon fiber cloth to both sides of the window wall body and bond and fix them to both sides of the window wall body.

[0040] Under horizontal force, the horizontal load-bearing capacity of the spandrel wall can be increased by about 20% due to the reinforcement effect of the cross-fiber carbon fiber cloth layers on the spandrel wall body.

[0041] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
