Description

Technical Field

[0001] This utility model relates to the field of concrete partition wall technology, and in particular to a modular structure of a lightweight concrete partition wall. Background Technology

[0002] Lightweight concrete partition walls, widely used in modern architecture, offer significant construction convenience due to their modular design. Currently, most lightweight concrete partition wall modules are assembled using precisely designed male and female tenons. During construction, only a small amount of mortar needs to be applied to the joints to complete the rapid assembly of the wall. This construction method, due to its simplicity and ease of operation, greatly shortens the construction cycle and reduces labor costs, making it a widely adopted splicing technology in the industry.

[0003] The modular connections in lightweight concrete partition walls rely excessively on the hard contact of tenons and mortises, lacking effective flexible connection designs. Because the hard contact of the tenons and mortises lacks a buffer mechanism, stress easily concentrates at the joints when the wall is subjected to external forces or temperature changes, making the joint area a weak point. Furthermore, lightweight concrete itself has poor crack resistance; over long-term use, uneven stress at the wall joints easily leads to cracking, affecting the wall's integrity and durability. Utility Model Content

[0004] In view of this, the embodiments of this utility model provide a modular structure for a lightweight concrete partition wall, which solves the technical problem of the lack of a flexible connection structure at the modular joint of the lightweight concrete partition wall.

[0005] An embodiment of this utility model provides a modular structure for a lightweight concrete partition wall, comprising: At least two partition wall bodies, each with a male tenon and a female tenon that fit together on both sides, and a splicing groove on both sides of each partition wall body; At least one connecting structure is provided at the two interlocking slots of two adjacent partition wall bodies, the connecting structure including a flexible connecting structure and a pad; The flexible connection structure includes a steel mesh and two positioning blocks. The steel mesh is connected between the two positioning blocks. The two positioning blocks position the steel mesh perpendicular to the splicing groove on the surface of the partition wall body, so that the steel mesh and the splicing groove are arranged in a vertical cross. The pad is placed in the two adjacent splicing grooves of the two partition wall bodies. The pad hides the flexible connection structure and covers the splicing grooves, thus filling the gap between the two partition wall bodies.

[0006] Furthermore, the surface of the partition wall body is provided with tie grooves on both sides thereon, and the steel mesh is attached to the inner wall surface of the tie grooves.

[0007] Furthermore, one end of the pull groove is connected to the splicing groove to form a T-shape, and the end of the pull groove away from the splicing groove is connected to a positioning groove; The positioning block corresponds to and fits the positioning groove, and the width of the positioning groove is greater than that of the pull groove.

[0008] Furthermore, the positioning block and the positioning groove are rectangular in shape.

[0009] Furthermore, the pad includes a fixing layer, a concrete layer, and a putty layer. The fixing layer is attached to the steel mesh, and the thicknesses of the concrete layer and the putty layer are configured to fill the splicing groove and make the putty layer flush with the surface of the partition wall body.

[0010] Furthermore, the shape of the fixing layer corresponds to the cross shape formed by the splicing groove and the two pull grooves, and the fixing layer is provided with an avoidance groove on the side facing the steel mesh, the avoidance groove allowing the vertical section of the fixing layer to fit into the splicing groove.

[0011] Furthermore, a jointing mortar is provided between the fixing layer and the matching groove to eliminate the gap between the pad and the matching groove.

[0012] Furthermore, the cross-shaped shape of the pad is divided into a vertical long section and a horizontal short section. The length of the vertical long section of the pad is configured to be the same as that of the splicing groove, and the length of the horizontal short section of the pad is configured to be the same as that of the steel mesh.

[0013] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: The modular structure of the lightweight concrete partition wall of this utility model achieves tight splicing of adjacent partition walls through a soft connection structure. At the same time, the T-shaped structure design of the splicing groove and the tie groove provides a stable space for the embedding of the steel mesh and positioning blocks, further enhancing the connection strength of the wall. The cross-shaped design of the pad block, combined with the multi-layer structure of the fixing layer, concrete layer and putty layer, not only achieves seamless filling of the splicing groove, but also eliminates splicing gaps through the filling of joint mortar, ensuring the flatness and aesthetics of the wall surface. Through the above-mentioned optimized design, the modular partition wall has significant advantages in terms of overall performance and aesthetics, and is suitable for scenarios in modern buildings where the functionality and aesthetics of partition walls are highly demanding.

[0020] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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 this utility model based on the specific circumstances.

[0021] Please refer to Figures 1 to 3 The present invention provides a modular structure for a lightweight concrete partition wall, including a partition wall body 1, a flexible connection structure and a pad block 9. The partition wall body 1 has male tenons 2 and female tenons 3 that fit together on both sides. The design of the male tenons 2 and female tenons 3 allows adjacent partition wall bodies 1 to be tightly spliced.

[0022] Both sides of the partition wall body 1 are provided with matching grooves 4. The depth of the matching grooves 4 is designed so that they do not contact the positions of the male tenon 2 and the female tenon 3. In actual construction, after the male tenon 2 and the female tenon 3 are aligned and spliced ​​together, the matching groove 4 located at the male tenon 2 of one partition wall body 1 and the matching groove 4 located at the female tenon 3 of the other partition wall body 1 are connected to each other to form a complete vertical groove. The surface of the matching groove 4 can be coated with caulking mortar so that there are no gaps at the joint of the male tenon 2 and the female tenon 3.

[0023] In this embodiment, the surface of the partition wall body 1 is also provided with a tie groove 5, which is used to embed a flexible connection structure to enhance the integrity of the wall. One end of the tie groove 5 is connected to the splicing groove 4 to form a T shape, and the end of the tie groove 5 away from the splicing groove 4 is connected to a positioning groove 6, the width of which is greater than that of the tie groove 5.

[0024] Furthermore, the flexible connection structure includes a steel mesh 7 and two positioning blocks 8. The two ends of the steel mesh 7 are respectively connected to the two positioning blocks 8 and embedded into the surface of the partition wall body 1 through the interlocking grooves 5. The arrangement direction of the steel mesh 7 is perpendicular to the interlocking grooves 4, forming a cross-shaped structure. Since the gap formed by the interlocking of the two partition wall bodies 1 is consistent with the length direction of the interlocking grooves 4, the steel mesh 7, perpendicular to the interlocking grooves 4, connects with the two partition wall bodies 1, thus providing reinforcement within the wall.

[0025] To ensure the connection strength between the steel mesh 7 and the positioning block 8, the ends of the steel mesh 7 can be pre-welded to the positioning block 8, and then the entire flexible connection structure is embedded and fixed in the tie groove 5. Simultaneously, a positioning groove 6 is designed at the far end of the tie groove 5, and the shape of the positioning groove 6 matches that of the positioning block 8. By inserting the positioning block 8 into the positioning groove 6, displacement of the flexible connection structure in the horizontal direction of the wall can be further prevented.

[0026] In an optional embodiment, the positioning block 8 and the positioning groove 6 are rectangular in shape, but they can also be set to easily processed shapes such as circles.

[0027] The spacer block 9 consists of a fixing layer 91, a concrete layer 92, and a putty layer 93. The fixing layer 91 is adhered to the steel mesh 7 and fixed within the interlocking groove 4 using adhesive or caulking mortar. To accommodate the cross-shaped structure, the fixing layer 91 is designed as a cross with a long vertical section and a short horizontal section. It can be made of high-strength, lightweight building materials, such as fiber-reinforced polymer (FRP) or high-density polyethylene (HDPE), providing sufficient tensile and compressive strength while reducing the weight of the wall.

[0028] It should be noted that the cross shape of the pad 9 is divided into a long vertical section and a short horizontal section. The length of the long vertical section of the pad 9 is the same as that of the matching groove 4, and the length of the short horizontal section of the pad 9 is the same as that of the steel mesh 7. The shape of the fixing layer 91 corresponds to the cross shape formed by the matching groove 4 and the two pairs of pull grooves 5. The side of the fixing layer 91 facing the steel mesh 7 is provided with an avoidance groove 911. The space of the avoidance groove 911 is sufficient to accommodate the steel mesh 7, and the surface of the steel mesh 7 is in close contact with the avoidance groove 911 to stabilize the position of the steel mesh 7. In this way, the vertical section of the fixing layer 91 can fit into the matching groove 4. In addition, the space between the fixing layer 91 and the matching groove 4 is filled with joint mortar to eliminate gaps and ensure the integrity and aesthetics of the wall.

[0029] A concrete layer 92 is filled outside the fixing layer 91 to ensure a stable connection between the fixing layer 91 and the sidewall of the joint 4. A putty layer 93 is then applied over the surface of the concrete layer 92 to make it flush with the surface of the partition wall body 1.

[0030] In this embodiment, the putty layer 93, in addition to smoothing the surface, can also integrate multiple functions such as waterproofing, fireproofing, and sound insulation. For example, polymer-modified putty can be selected, which has better adhesion and water resistance, and is also compatible with subsequent wall decoration materials (such as latex paint, wallpaper, etc.).

[0031] In actual construction, the partition wall body 1 is first spliced ​​together with the male tenon 2 and the female tenon 3, while a flexible connection structure consisting of steel mesh 7 and positioning blocks 8 is inserted. Then, spacers 9 are embedded into the splicing grooves 4 and fixed in place. After the entire structure is assembled, the spliced ​​parts of the wall, filled by the flexible connection structure and spacers 9, possess good rigidity and integrity, while avoiding the wall gap problems caused by traditional splicing methods.

[0032] In this document, the directional terms such as front, back, top, and bottom are defined based on the position of the components in the accompanying drawings and their relative positions to each other, solely for the purpose of clarity and convenience in expressing the technical solution. It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0033] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
