Abstract
Description
Technical Field
[0001] This invention relates to the field of reinforcement technology for window spans in masonry structures, and in particular to a top-to-bottom binding reinforcement structure and method for the inner side of a window span in masonry structures. 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 binding the inner side of the masonry window span wall with upper and lower binding, which can restrain the masonry wall, enhance the vertical and horizontal bearing capacity of the window span wall structure, effectively improve the integrity and anti-falling and collapse ability of the window span wall structure, and effectively improve the overall stability and safety of the window span wall structure. Summary of the Invention
[0004] The purpose of this invention is to provide a top-to-bottom binding reinforcement structure and method for the inner side of a masonry window pier wall, in order to solve the problems existing in the prior art. This invention can restrain the masonry wall, enhance the vertical and horizontal bearing capacity of the window pier wall structure, effectively improve the integrity and anti-falling / collapse ability of the window pier wall structure, and effectively improve the overall stability and safety of the window pier wall structure.
[0005] To achieve the above objectives, the present invention provides the following solution:
[0006] This invention provides a masonry structure with an inner wall reinforcement structure consisting of a window span, comprising: a window span body, an annular placement station, an annular carbon fiber cloth, an adhesive layer, a first filler, and a second filler. The window span body is positioned between two adjacent windows on a wall. The annular placement station includes a first replacement groove, a second replacement groove, and a first sidewall and a second sidewall on both sides of the window span body. The first replacement groove is a groove formed by removing a first depth of mortar joint from the top inner side of the window span body, and the second replacement groove is a groove formed by removing a first depth of mortar joint from the bottom inner side of the window span body. The annular carbon fiber cloth is sequentially fixed in the placement station to form a closed constraint on the inner side of the window span body. The adhesive layer is disposed between the annular carbon fiber cloth and the annular placement station to bond and fix the annular carbon fiber cloth to the annular placement station. The first filler is used to fill the first replacement groove, and the second filler is used to fill the second replacement groove.
[0007] Preferably, the depth of the first depth is the same as the width of the annular carbon fiber cloth.
[0008] Preferably, the width of the annular carbon fiber cloth is 95mm to 105mm.
[0009] Preferably, the adhesive layer is formed by uniformly applying structural adhesive to the annular placement station.
[0010] Preferably, the first filler is formed by filling the first replacement groove with high-strength cement mortar.
[0011] Preferably, the second filler is formed by filling the second replacement groove with high-strength cement mortar.
[0012] The present invention also provides a method for reinforcing a masonry structure with an upper and lower binding reinforcement structure on the inner side of the window pier as described in any of the preceding claims, characterized by comprising the following steps:
[0013] S1: The first replacement groove is formed by removing a first depth of mortar joint at the top of the window wall body, and the second replacement groove is formed by removing a first depth of mortar joint at the bottom of the window wall body.

[0015] S3: Apply an adhesive layer to the annular placement station;
[0016] S4: Bond and fix the annular carbon fiber cloth to the adhesive layer to fix the annular carbon fiber cloth on the annular placement position;
[0017] S5: The first displacement groove is filled to form the first filler, and the second displacement groove is filled to form the second filler;
[0018] S6: Curing the first filler and the second filler.
[0019] The present invention achieves the following technical effects compared to the prior art:
[0020] This invention provides a binding reinforcement structure and method for the inner side of a masonry window span wall. A first replacement groove is formed by removing mortar to a first depth from the top joint of the window span wall body, and a second replacement groove is formed by removing mortar to a first depth from the bottom joint of the window span wall body. The first and second replacement grooves, along with the first and second sidewalls on both sides of the window span wall body, form a ring-shaped placement position. A ring-shaped carbon fiber cloth is bonded and fixed to the ring-shaped placement position using an adhesive layer to create a closed constraint on the inner side of the window span wall body. Then, a first filler is used to fill the first replacement groove, and a second filler is used to fill the second replacement groove. The ring-shaped carbon fiber cloth is adhered top, bottom, left, and right, forming a closed structure that constrains the window span wall, enhancing the vertical and horizontal load-bearing capacity of the window span wall structure. Under earthquake action, window span walls are prone to X-shaped cracks and localized wall collapse. By adding the ring-shaped carbon fiber cloth for binding reinforcement, the integrity and anti-collapse ability of the window span wall structure are effectively improved, effectively enhancing the overall stability and safety of the window span wall structure.

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.
[0027] The purpose of this invention is to provide a top-to-bottom binding reinforcement structure and method for the inner side of a masonry window pier wall, in order to solve the problems existing in the prior art. This invention can restrain the masonry wall, enhance the vertical and horizontal bearing capacity of the window pier wall structure, effectively improve the integrity and anti-falling / collapse ability of the window pier wall structure, and effectively improve the overall stability and safety of the window pier wall structure.
[0028] 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

The window sill body 1 is positioned between two adjacent windows on a wall. The annular placement station 5 includes a first replacement groove, a second replacement groove, and first and second sidewalls on both sides of the window sill body 1. The first replacement groove is a groove formed by removing a first depth of mortar joint from the top inner side of the window sill body 1, and the second replacement groove is a groove formed by removing a first depth of mortar joint from the bottom inner side of the window sill body 1. The annular carbon fiber cloth 2 is sequentially fixed in the placement station to form a closed constraint on the inner side of the window sill body 1. The adhesive layer 3 is used to be placed between the annular carbon fiber cloth 2 and the annular placement station 5 to bond and fix the annular carbon fiber cloth 2 to the annular placement station 5. The first filler 4 is used to fill the first replacement groove. The second filler is used to fill the second replacement groove. The first replacement groove is formed by removing a first depth of mortar from the top mortar joint of the window sill body 1, and the first depth of mortar is removed from the bottom mortar joint of the window sill body 1. A second replacement groove is formed. The first replacement groove, the second replacement groove, and the first and second sidewalls on both sides of the window wall body 1 form an annular placement station 5. The annular carbon fiber cloth 2 is bonded and fixed to the annular placement station 5 through the adhesive layer 3 to form a closed constraint on the inner side of the window wall body 1. Then, the first replacement groove is filled by the first filler 4, and the second replacement groove is filled by the second filler. The annular carbon fiber cloth 2 is pasted up, down, left, and right to form a closed constraint on the window wall, which enhances the vertical and horizontal bearing capacity of the window wall structure.

[0033] In a preferred embodiment, the width of the adhesive layer 3 is the same as the width of the annular carbon fiber cloth 2. Making the width of the adhesive layer 3 the same as the width of the annular carbon fiber cloth 2 can firmly bond the annular carbon fiber cloth 2.
[0034] In a preferred embodiment, the first filler 4 is made by filling the first replacement groove with high-strength cement mortar, which is easy to obtain and has high material strength, and can effectively enhance the constraint ability of the annular carbon fiber cloth 2.
[0035] In a preferred embodiment, the second filler is made by filling the second replacement groove with high-strength cement mortar, which is easy to obtain and has high material strength, and can effectively enhance the constraint ability of the annular carbon fiber cloth 2.
