Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a connection structure between new and old brick walls. Background Technology
[0002] In buildings, room partition walls are mostly made of brick, such as perforated bricks or hollow bricks. During the use of a building, the original layout often fails to meet the new needs of the owner, leading to a redesign of the interior space and the construction of new partition walls. To prevent cracking at the joint between the old and new walls and to improve the tightness of the connection, it is common practice to drill holes in the old wall and install reinforcing bars to connect the old and new walls. However, if the old wall is constructed of hollow bricks, it is impossible to effectively install reinforcing bars, affecting the connection between the old and new walls. Utility Model Content
[0003] This utility model addresses the problem that when connecting old and new walls, it is impossible to install rebar in the old wall constructed with hollow bricks, thus affecting the connection between the old and new walls. The specific technical solution adopted is: a connection structure for connecting two walls in a T-shape, including: a connector and a connecting body. The connector is composed of an end plate and a rod connected in a T-shape. The end plate of the connector is located on the outside of the wall, and the rod of the connector passes through one wall and is placed inside the other wall. The connecting body is located in the gap between the two walls.
[0004] A further improvement is that at least two rods are connected to the end plate.
[0005] A further improvement is that each of the rod ends is provided with a separate end plate, and at least two of the end plates are provided with a common pad between them and the wall.
[0006] A further improvement is that the connector is convex.
[0007] A further improvement is that the connecting body is made of plain concrete.
[0008] A further improvement is that the gap between the connector and the wall, as well as the outside of the end plate, are covered with wire mesh.
[0009] A further improvement is that the outer surface of the wire mesh is covered with a cement mortar plaster layer.
[0010] The beneficial effects of this utility model are:
[0011] The new and old brick wall connection structure provided by this utility model ensures the tightness of the connection between the new and old walls by combining the connector and the connecting body. It effectively solves the problem that it is inconvenient to use conventional tie bars to connect the new and old walls when the old wall is a hollow brick. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0017] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of a utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0019] In utility models, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.
[0020] Example 1
[0021] like Figure 1 and Figure 2 As shown, this utility model provides a connection structure for old and new brick walls, used for connecting two walls (old wall 10 and new wall 20) in a T-shape. It includes a connector 30 and a connecting body 40. The connector 30 consists of a T-shaped end plate and a rod 301. The end plate is preferably a steel plate, and the rod 301 is preferably a reinforcing bar. One end of the rod 301 is welded to the end plate. In use, the old wall 10 has pre-drilled holes. The rod 301 of the connector 30 passes through the outside of the old wall and then through the connecting body 40, with the end of the rod 301 remaining inside the new wall 20. The connecting body 40 fills the gap between the two walls. The connectors 30 are arranged horizontally, with multiple connectors arranged according to the wall thickness, forming connector groups. Each group of connectors is spaced apart along the height of the new wall from bottom to top.
[0022] A gap is left between the old wall and the new wall (the gap is filled with a connector 40) to improve the construction efficiency of the new wall. The use of the connector 40 and the connectors together increases the integrity of the old and new walls.
[0023] The new and old brick wall connection structure provided by this utility model ensures the tightness of the connection between the new and old walls by combining the connector and the connecting body. It effectively solves the problem that it is inconvenient to use conventional tie bars to connect the new and old walls when the old wall is a hollow brick.
[0024] A further improvement is made to include an end plate in each connection structure, on which at least two parallel rods 301 are welded and fixed. This structure requires high precision in the openings in the wall; otherwise, the connectors may not be able to be inserted, or may require enlarging the holes, leading to a complex construction process.
[0025] A further improvement is that the connector 40 is convex-shaped to facilitate its connection with the end of the new wall 20 and to improve the connection strength.
[0026] A further improvement is that the connecting body 40 is made of plain concrete to reduce construction costs and improve construction efficiency.
[0027] like Figure 3 As shown, in order to further improve the connection strength at the wall connection gap, the technical solution is further improved by covering the outside of the connection gap between the connector 40 and the wall and the outside of the end plate with wire mesh 50.
[0028] A further improvement is that the outer surface of the wire mesh 50 is covered with a cement mortar plaster layer 60.
[0029] Example 2
[0030] like Figure 1 and Figure 2As shown, this utility model provides a connection structure for old and new brick walls, used for connecting two walls (old wall 10 and new wall 20) in a T-shape. It includes a connector 30 and a connecting body 40. The connector 30 consists of a T-shaped end plate and a rod 301. The end plate is preferably a steel plate, and the rod 301 is preferably a reinforcing bar. One end of the rod 301 is welded to the end plate. In use, the old wall 10 has pre-drilled holes. The rod 301 of the connector 30 passes through the outside of the old wall and then through the connecting body 40, with the end of the rod 301 remaining inside the new wall 20. The connecting body 40 fills the gap between the two walls. The connectors 30 are arranged horizontally, with multiple connectors arranged according to the wall thickness, forming connector groups. Each group of connectors is spaced apart along the height of the new wall from bottom to top.
[0031] A gap is left between the old wall and the new wall (the gap is filled with a connector 40) to improve the construction efficiency of the new wall. The use of the connector 40 and the connectors together increases the integrity of the old and new walls.
[0032] The new and old brick wall connection structure provided by this utility model ensures the tightness of the connection between the new and old walls by combining the connector and the connecting body. It effectively solves the problem that it is inconvenient to use conventional tie bars to connect the new and old walls when the old wall is a hollow brick.
[0033] A further improvement is that each of the rods 301 is provided with a separate end plate at its end, and at least two of the end plates are provided with a common pad 31 between themselves and the wall (the old wall 10).
[0034] A further improvement is that the connector 40 is convex-shaped to facilitate its connection with the end of the new wall 20 and to improve the connection strength.
[0035] A further improvement is that the connecting body 40 is made of plain concrete to reduce construction costs and improve construction efficiency.
[0036] like Figure 3 As shown, in order to further improve the connection strength at the wall connection gap, the technical solution is further improved by covering the outside of the connection gap between the connector 40 and the wall and the outside of the end plate with wire mesh 50.
[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
