Description

Technical Field

[0001] The utility model relates to the technical field of building wall processing, in particular to a building wall structure. Background Art

[0002] In modern construction, some new buildings utilize cast-in-place load-bearing exterior walls. Reinforcing the mold is a critical step in ensuring the quality of the wall's finished form. Whether using permanent or temporary molds, through-wall bolts are commonly used to prevent the mold from expanding due to concrete pressure during pouring. While through-wall bolts effectively enhance mold stability, removing these temporary reinforcements after pouring leaves holes in the wall.

[0003] These filling holes need to be sealed with waterproof plugging materials to ensure the overall waterproof performance of the wall is not affected. Traditional methods often require plugging first, then connecting the exterior wall to the outer cladding after the material solidifies. During this process, additional holes need to be drilled in the exterior wall, and then the outer cladding and exterior wall need to be connected using connecting components. This connection method is time-consuming and reduces construction efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a building wall structure, which simplifies the construction steps, reduces the construction time, reduces the labor cost and improves the construction efficiency by improving the building wall structure.

[0005] To achieve the above-mentioned objectives, the present invention provides a building wall structure, comprising a wall, an outer covering, and a connecting assembly, wherein the wall has a filling hole, which penetrates the wall in the thickness direction of the wall, a fastener is provided at one end of the connecting assembly, the fastener is fixed to the filling hole, and the other end of the connecting assembly is fixed to the outer covering.

[0006] By adopting the technical solution in the present application, the filling holes in the wall are used as connection holes for connecting to the outer covering, which not only avoids the need for additional holes in the outer wall to install the outer covering, but also can simultaneously achieve the sealing of the filling holes and the installation of the outer covering, thereby simplifying the construction steps, reducing construction time, reducing labor costs, and improving construction efficiency.

[0007] Optionally, the fastener includes a screw, a nut, and a sealing gasket. The end of the screw closest to the outer covering is defined as a connection end, located outside the filling hole and connected to the nut. The sealing gasket is sleeved over the connection end and located between the nut and the wall. The provision of the sealing gasket can seal the filling hole, improving its waterproof sealing performance.

[0008] Optionally, the connection assembly further includes an adapter and a wall connection member for connecting to the outer covering, the adapter including an adapter plate, a portion of which is sleeved over the connection end and positioned between the nut and the sealing gasket; and a portion of which is threadedly connected to the wall connection member, at least a portion of which is sleeved over the connection end. The adapter and the wall connection member are provided to connect the fastener to the wall connection member, thereby securely connecting the wall to the outer covering.

[0009] Optionally, in one embodiment, the adapter further includes two opposing support plates, the adapter plate being perpendicular to the support plate and connected to one end of the support plate, with the other ends of the support plates each being configured to abut against the wall; the sealing gasket is positioned between the other ends of the support plates and the wall. The support plates of the connector press the sealing gasket against the wall, thereby enhancing the sealing performance of the sealing gasket.

[0010] Alternatively, in another embodiment, the portion of the adapter plate that is sleeved over the connection end is defined as the first plate portion, and the first plate portion is in contact with the surface of the sealing gasket away from the wall. Thus, the first plate portion is pressed against the wall and in contact with the sealing gasket, thereby increasing the contact area between the sealing gasket and the wall.

[0011] Optionally, the portion of the adapter plate threadedly connected to the wall connector is defined as a second plate portion, the second plate portion being spaced apart from the wall, and a support plate being provided at one end of the second plate portion remote from the first plate portion, the support plate being configured to abut against the wall; the sealing gasket being positioned between the support plate and the wall. The support plate of the connector presses the sealing gasket against the wall, thereby enhancing the sealing performance of the sealing gasket.

[0012] Optionally, the filling hole includes a first hole segment and a second hole segment, wherein the second hole segment is further away from the outer cover than the first hole segment; the fastener is connected to the first hole segment, and the second hole segment is filled with a plugging member. By providing the plugging member, the waterproof performance of the filling hole can be further enhanced.

[0013] Optionally, a mesh is disposed within the first hole segment, surrounding the inner wall of the filling hole. In a radial direction of the filling hole, the mesh is positioned between the wall of the filling hole and the fastener. Structural adhesive is then filled between the fastener and the wall of the filling hole. Thus, during construction, placing the mesh within the filling hole, then filling it with adhesive, and then installing the fastener increases connection stability, prevents loosening, and improves sealing.

[0014] Optionally, the grid piece is in a cylindrical structure. The connection strength between the fastener and the filling hole is increased by providing the grid piece in a cylindrical structure.

[0015] Optionally, in the axial direction of the filling hole, one end of the grid member exceeds the end of the corresponding side of the fastener to abut against the blocking member.

[0016] This provides a certain redundancy for the installation of the fastener and ensures the connection strength between the fastener and the filling hole.

[0023] The utility model provides a building wall structure, which simplifies construction steps, reduces construction time, reduces labor costs, and improves construction efficiency by improving the building wall structure.

[0024] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Relational terms such as “first” and “second” are used merely to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.

[0026] Please refer to Figure 1 and Figure 2 , Figure 1 This is a partial structural diagram of a building wall structure in an embodiment of the present utility model; Figure 2 yes Figure 1 A local enlarged schematic diagram in .

[0027] When constructing exterior walls of new buildings using cast-in-place load-bearing wall construction, mold reinforcement is a critical step in ensuring the quality of the wall. Whether using permanent or temporary molds, through-wall bolts are commonly used to prevent the mold from expanding due to concrete pressure during pouring. While through-wall bolts effectively enhance mold stability, they also leave holes in the wall when these temporary reinforcements are removed after pouring.

[0028] As shown in the figure, the present invention provides a building wall structure, including a wall 1, an outer covering 4, and a connecting assembly. The wall 1 has a filling hole 13, which penetrates the wall 1 in the thickness direction of the wall 1. The outer covering 4 covers the outside of the wall 1. The wall 1 has an inner surface 12 and an outer surface 11. The inner surface 12 is used to enclose an indoor space. The outer surface 11 is opposite to the inner surface 12 in the thickness direction. The outer surface 11 is covered with the outer covering 4. A fastener 2 is provided at one end of the connecting assembly, and the fastener 2 is fixed to the filling hole 13. The other end of the connecting assembly is fixed to the outer covering 4. The outer covering 4 can be an insulation board, a decorative board, or other component covering the outer surface 11 of the wall 1. The covering includes the outer covering 4 being attached to the wall 1, or the outer covering 4 being spaced apart from the wall 1. The outer covering 4 only needs to wrap around the outer surface 11 of the wall 1.

[0029] Specifically, the connection assembly also includes an adapter 52 and a wall connection member 51 for connecting to the outer covering 4. One end of the wall connection member 51 can be fixedly connected, plugged into, or threaded to the outer covering 4. The other end of the wall connection member 51 is secured to the fastener 2 via the adapter 52, thereby achieving a fixed connection between the wall 1 and the outer covering 4. The fastener 2 can be an anchor such as an expansion bolt or a tension rod. The wall connection member 51 can adopt a conventional connection structure and is not a major improvement of the present invention and will not be described in detail here.

[0030] By adopting the technical solution of the present application, the filling hole 13 of the wall 1 is used as a connection hole connected to the outer covering 4, which not only avoids the need for additional drilling on the outer wall to install the outer covering 4, but also can simultaneously achieve the sealing of the filling hole 13 and the installation of the outer covering 4, thereby simplifying the construction steps, reducing construction time, reducing labor costs, and improving construction efficiency.

[0031] In a specific embodiment, the filling hole 13 includes a first hole segment 131 and a second hole segment 132, which are connected along the thickness direction of the wall 1. The apertures of the first hole segment 131 and the second hole segment 132 can be the same or different, and are not specifically limited here. The second hole segment 132 is farther away from the outer covering 4 than the first hole segment 131. That is, the first hole segment 131 penetrates the outer surface 11 of the wall 1 to form an opening 111 on the outer surface 11, and the second hole segment 132 penetrates the inner surface 12 of the wall 1 to form an opening 121 on the inner surface 12. The fastener 2 enters through the opening 111 on the outer surface 11 and connects to the first hole segment 131. The second hole segment 132 is filled with a sealing member 7, which separates the opening 121 on the inner surface 12 from the opening 111 on the outer surface 11. By providing the sealing member 7, the waterproof performance of the filling hole 13 can be further enhanced. The sealing member 7 may be a polyurethane foam material, a cement-based permeable crystallization waterproof material, a waterproof mortar, a waterproof concrete, or the like.

[0032] In the above embodiment, a mesh member 6 is provided in the first hole section 131. The mesh member 6 is provided around the inner wall of the filling hole 13. In the radial direction of the filling hole 13, the mesh member 6 is located between the hole wall of the filling hole 13 and the fastener 2. Structural adhesive is filled between the fastener 2 and the hole wall of the filling hole 13. Therefore, during the construction process, the mesh member 6 is placed in the filling hole 13, the adhesive is re-filled, and the fastener 2 is re-installed to increase the connection stability, prevent loosening, and improve the sealing. The mesh member 6 can form a complete closed cylindrical shape around the inner wall of the filling hole 13, or it can partially surround the inner wall of the filling hole 13 to form an arc-shaped structure. In addition, the mesh member 6 can surround the filling hole 13 in one layer, or it can be a multi-layer structure around the filling hole 13.

[0033] Optionally, the mesh member 6 is a circumferentially closed cylindrical structure. The mesh of the mesh member 6 is a quadrilateral structure, so that the radial dimension of the cylindrical structure can increase or decrease as the quadrilateral structure deforms. In this embodiment, the radial dimension of the mesh member 6 must be larger than the radial dimension of the fastener 2. Furthermore, the radial dimension of the mesh member 6 can also be consistent with the diameter of the filling hole 13, or smaller than the diameter of the filling hole 13.

[0034] During the actual installation process, the mesh member 6 is inserted into the filling hole 13, and the gun head of the structural glue is inserted into the filling hole 13 through the opening 111 of the outer surface 11, and then into the interior of the cylindrical mesh member 6, and the glue is poured into the interior of the mesh member 6. While pouring the glue, the gun head of the glue gun is gradually moved outward, so that the structural glue is gradually injected into the mesh member 6 in the axial direction of the filling hole 13, and then the glue gun is pulled out from the opening 111 of the outer surface 11, and then the expansion bolt is inserted into the mesh member 6, and the expansion bolt is expanded. In the process of radial expansion of the expansion bolt, part of the structural glue in the mesh member 6 will be squeezed to the outside of the mesh member 6 through the mesh hole, thereby evenly squeezing the structural glue to the inner peripheral wall of the filling hole 13. The cylindrical mesh member 6 is provided to increase the connection strength between the fastener 2 and the filling hole 13.

[0035] Specifically, when the expansion bolt is inserted into the interior of the mesh member 6, a gap is formed between the outer wall of the expansion bolt and the inner wall of the filling hole 13. The mesh member 6 is arranged in the gap and is also filled with structural adhesive. That is, after installation, the mesh member 6 is buried in the structural adhesive.

[0036] In the above-described embodiment, in the axial direction of the filling hole 13, one end of the mesh member 6 extends beyond the corresponding end of the fastener 2 to abut against the plugging member 7. This creates redundancy, ensuring that the portion of the expansion bolt within the filling hole 13 is securely connected to the wall of the filling hole 13 through the mesh member 6, thereby ensuring the connection strength between the fastener 2 and the filling hole 13. The same operation is employed when the fastener 2 is a tension rod or other anchor. This allows the mesh member 6 and structural adhesive to fill the gap between the outer peripheral wall of the fastener 2 and the inner wall of the filling hole 13, thereby improving the tensile strength of the wall structure in this application.

[0037] In other embodiments of the present application, the fastener 2 includes a screw, a nut, and a sealing gasket 3. The end of the screw near the outer covering 4 is defined as a connection end. The connection end is located outside the filling hole 13, and the rest of the screw, excluding the connection end, is located inside the filling hole 13. The connection end is connected to the nut. The sealing gasket 3 is sleeved on the connection end, located between the nut and the wall 1, and attached to the outer surface 11 of the wall 1. The provision of the sealing gasket 3 can seal the filling hole 13, improving the waterproof sealing performance of the filling hole 13. The sealing gasket 3 is made of rubber, silicone, plastic, or metal.

[0038] The screw is passed through the sealing gasket 3, which is an annular structure, and its inner ring side is tightly against the screw; the gap between the screw and the opening 111 of the outer surface 11 is covered by the sealing gasket 3, thereby sealing the opening 111 of the outer surface 11 of the filling hole 13, thereby preventing water vapor from entering the filling hole 13 through the gap.

[0039] In the above embodiment, adapter 52 includes an adapter plate 521, which is positioned parallel to wall 1. A portion of adapter plate 521 is positioned over the connection end and located between the nut and sealing gasket 3. A portion of adapter plate 521 is threadedly connected to wall connection member 51, with at least a portion of wall connection member 51 positioned over the connection end. The adapter 52 and wall connection member 51 are connected to each other, thereby securing wall 1 to outer covering 4. This embodiment will be described in detail below using two specific implementations. Example 1

[0040] In this embodiment, the adapter 52 has an approximately Z-shaped structure, and the portion of the adapter plate 521 that is sleeved on the connection end is defined as the first plate portion 521a, and the portion of the adapter plate 521 that is threadedly connected to the wall connecting member 51 is defined as the second plate portion 521b. In the height direction, the distances between the first plate portion 521a and the second plate portion 521b and the outer surface 11 of the wall 1 are different. In the height direction of the wall 1, the first plate portion 521a is located on the upper side of the second plate portion 521b; the end where the first plate portion 521a and the second plate portion 521b are close to each other is connected by a connecting plate 523, and the adapter plate 521 is arranged perpendicular to the first plate portion 521a and the second plate portion 521b, and a support plate is also provided at the end of the second plate portion 521b away from the first plate portion 521a, which is defined as the first support plate 522, and the first support plate 522 is arranged perpendicular to the second plate portion 521b, and the first support plate 522 is arranged parallel to the connecting plate 523.

[0041] In this embodiment, the first plate portion 521a is attached to the surface of the sealing gasket 3 that is away from the wall 1. That is, the first plate portion 521a defines a mounting hole, through which the screw passes and enters the filling hole 13 through the opening 111 of the mounting hole-outer surface 11. On the projection of the screw, the first plate portion 521a covers the opening 111 of the outer surface 11. The aforementioned sealing gasket 3 is disposed between the first plate portion 521a and the outer surface 11 of the wall 1. The nut is located on the side of the first plate portion 521a opposite the sealing gasket 3. When the nut is tightened, it is pressed against the sealing gasket by the first plate portion 521a. This ensures the locking force of the nut while preventing deformation of the sealing gasket 3, significantly improving the waterproof sealing performance of the filling hole 13.

[0042] Optionally, the second plate portion 521b is spaced apart from the wall 1. A first support plate 522 is provided at one end of the second plate portion 521b away from the first plate portion 521a. The first support plate 522 is used to abut against the wall 1. The first support plate 522, the connecting plate 523, and the second plate portion 521b enclose a receiving cavity. The wall connecting member 51 is connected to the second plate portion 521b by bolts. The bottom of the bolts passes through the second plate portion 521b into the receiving cavity. The sealing gasket 3 extends to a position between the first support plate 522 and the wall 1 and is located between the first support plate 522 and the wall 1. The sealing gasket 3 is pressed against the wall 1 by the first support plate 522 of the connecting member, thereby improving the sealing performance of the sealing gasket 3.

[0043] In this embodiment, the sealing gasket 3 is located in the accommodating cavity and constitutes part of the wall of the accommodating cavity. The bolts fixedly connected to the wall connecting member 51 can also abut against the sealing gasket 3, thereby further preventing the sealing gasket 3 from deforming. While ensuring the fastening strength of the fastener 2, the waterproof performance of the filling hole 13 is ensured. Example 2

[0044] In this embodiment, the adapter plate 521 is not staggered, the first plate portion 521a and the second plate portion 521b are located in the same plane, and are both spaced apart from the outer surface 11 of the wall 1; the adapter 52 also includes at least two support plates arranged opposite to each other, which are defined as second support plates in this embodiment; the two second support plates are arranged opposite to each other along the height direction, thereby forming a U-shaped structure or a box-shaped structure with one end open; the adapter plate 521 is perpendicular to the second support plate and is connected to one end of the second support plate, and the other end of the second support plate is used to abut against the wall 1; sealing The gasket 3 extends outward from the adapter 52, and part of it is located between the other end of the second support plate and the wall 1; at the same time, the opening 111 of the outer surface 11 of the wall 1 is covered by the projection range of the first plate portion 521a in the same direction as the filling hole 13 in the axial projection range. In this way, the two second support plates are pressed against the outer part of the sealing gasket 3 covering the filling hole 13. In this way, during the tightening process of the fastener 2, the sealing gasket 3 can be prevented from being concave and deformed toward the side close to the filling hole 13, thereby ensuring the sealing performance of the sealing gasket 3 while ensuring the connection strength of the fastener 2.

[0045] Compared with the existing technology, this technical solution has the following advantages:

[0046] First, by adopting the technical solution of the present application, on the one hand, the filling hole 13 reserved in the wall 1 is utilized, replacing the original step of blocking the filling hole 13, while at the same time, there is no need to open an additional installation hole in the wall 1 to connect with the outer covering 4, thereby saving production processes and improving production efficiency.

[0047] Second, during actual use, the outer covering 4 of the building's wall structure will bear wind loads, thereby generating a pulling force on the fastener 2 in a direction away from the wall 1. By providing the mesh member 6 and the structural adhesive in conjunction with the fastener 2, the connection strength between the fastener 2 and the inner wall of the filling hole 13 in its radial direction is improved, thereby improving the axial pull-out resistance of the fastener 2.

[0048] Third, in this embodiment, the different structures of the adapter 52 are adapted to the sealing gasket 3 to avoid the sealing gasket 3 from being recessed toward the filling hole 13, thereby ensuring the fastening strength of the fastener 2 while also ensuring the sealing performance of the sealing gasket 3.

[0049] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help you understand the core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
