Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a ring beam formwork shell and building structure that does not require disassembly. Background Technology
[0002] Ring beams are used to prevent the adverse effects of uneven settlement of the foundation or large vibration loads on the building. Generally, reinforced concrete ring beams or reinforced brick ring beams should be set in the wall to enhance the overall rigidity of the brick and stone structure.
[0003] Traditionally, the construction of ring beams in masonry walls involves first erecting formwork, then tying reinforcing bars and pouring concrete. This method is cumbersome, time-consuming, and labor-intensive, and the quality of the ring beam may not meet construction requirements. Precast ring beam formwork has emerged as a solution. This formwork is directly connected to the wall, and concrete is poured inside after connection, eliminating the need for disassembly. Current ring beam formwork is precast U-shaped, with the horizontal bottom of the U-shape connecting to the wall below, and concrete poured into the resulting groove. However, aligning the flat bottom of the U-shaped formwork with the wall below is difficult. This requires numerous tools, significant time and manpower, and still often results in inaccurate alignment, affecting the quality and aesthetics of the finished product.
[0004] In view of the above, this utility model is hereby proposed. Utility Model Content
[0005] To solve one of the above-mentioned technical problems, this utility model provides a ring beam without dismantling the formwork and a building structure.
[0006] The primary objective of this application is to provide a ring beam without the need for formwork removal and a building structure, providing the following technical solution:
[0007] A ring beam non-removable mold shell includes a strip-shaped mold shell body. A bottom groove is formed on one side of the mold shell body, extending along the length direction of the mold shell body and penetrating the mold shell body. A top groove is formed on the other side of the mold shell body, extending along the length direction of the mold shell body and penetrating the mold shell body. The bottom groove and the top groove are located on opposite sides of the mold shell body. The depth of the top groove is greater than the depth of the bottom groove, and the ratio of the depth of the top groove to the depth of the bottom groove is (3~10):1.
[0008] Optionally, the ring beam non-removable formwork shell includes two side plates and a connecting plate located between the two side plates and connecting the two side plates respectively;

[0014] A building structure, comprising:
[0015] Exterior wall panels;
[0016] As described above, the ring beam non-removable formwork shell is fitted onto the upper edge of the outer wall panel through a bottom groove;
[0017] The ring beam concrete is filled in the top groove of the ring beam formwork shell that does not require demolding.
[0018] Optionally, the exterior wall panel has a main wall and a protruding strip located at the top of the main wall;

[0022] Optionally, one end of the fastener passes through the connecting plate of the ring beam's non-removable formwork and is connected to the outer wall panel, while the other end of the fastener is confined to the side of the connecting plate near the top groove.
[0023] Optionally, the building structure includes reinforcing ring beams;
[0024] The reinforcing bars of the ring beam are housed in the top groove, and the ring beam concrete covers the reinforcing bars of the ring beam.
[0025] Optionally, the exterior wall panel includes a foamed cement insulation layer and an outer protective layer;

[0039] Example 1
[0040] like Figures 1 to 4 As shown, this embodiment provides a ring beam non-removable mold shell, including a strip-shaped mold shell body. A bottom groove 101 is formed on one side of the mold shell body, extending along the length direction of the mold shell body and penetrating the mold shell body. A top groove 102 is formed on the other side of the mold shell body, extending along the length direction of the mold shell body and penetrating the mold shell body. The bottom groove 101 and the top groove 102 are located on opposite sides of the mold shell body. The groove depth of the top groove 102 is greater than the groove depth of the bottom groove 101, and the ratio of the groove depth of the top groove 102 to the groove depth of the bottom groove 101 is (3~10):1.
[0041] The ring beam formwork shell provided in this application consists of two parts: a bottom groove 101 for connecting the upper edge of the wall panel, and a top groove serving as the ring beam template for casting the ring beam. The overall length of the formwork shell is unlimited and can be cut to the required length according to structural needs. The formwork shell and wall panel are connected with bolts and sealed with grout. The depth ratio of the upper groove to the lower groove is (3-10):1, with the top groove being deeper than the bottom groove, ensuring a reliable and secure connection between the formwork shell and the wall panel. This ring beam formwork shell design saves manpower, resources, and time, and improves the quality and aesthetics of the finished ring beam.
[0042] When installing the ring beam membrane shell 1 onto the wall panel and pouring the ring beam, apply adhesive mortar to the upper part of the wall panel, place the ring beam membrane shell 1 on the wall panel, so that the upper part of the wall panel is embedded in the bottom groove 101 of the ring beam membrane shell 1, connect the ring beam membrane shell 1 to the wall panel using connectors, and finally inject ring beam concrete into the top groove 102. After the ring beam concrete solidifies, a complete ring beam is formed.
[0043] The bottom groove 101 of the ring beam formwork shell provided in this application has a groove width that matches the width of the wall to which it is installed. When the ring beam formwork shell 1 is installed onto the wall panel, the top of the wall panel is embedded in the bottom groove 101, which acts as a limit, allowing the ring beam formwork shell 1 to be quickly installed onto the wall panel without the need for calibration tools, and ensuring accurate alignment between the ring beam formwork shell 1 and the wall panel. This significantly saves manpower, resources, and time, and improves the quality and aesthetics of the finished ring beam.
[0044] The bottom groove 101 primarily serves to limit the movement between itself and the wall panel, while the top groove 102 is mainly used for pouring concrete to form the main body of the ring beam. The bottom groove 101 does not require a large depth, but the top groove 102 does. Therefore, the depth of the top groove 102 is greater than that of the bottom groove 101. Furthermore, the top groove 102 needs to be reinforced internally to ensure the strength of the finished ring beam. The bottom groove 101 also requires different depths depending on the thickness of the wall panel to ensure optimal performance. Extensive testing has shown that a ratio of (3-10):1 between the depths of the top groove 102 and the bottom groove 101 achieves good results for both. Preferably, the ratio of the depths of the top groove 102 to the bottom groove 101 is (5-8):1.
[0045] In some possible implementations, the ring beam formwork shell includes two side plates 11 and a connecting plate 12 located between and connecting the two side plates 11 respectively. The two side plates 11 form a top groove 102 and a bottom groove 101 on opposite sides of the connecting plate 12 along its thickness direction. This structure is simple, the manufacturing process is simple, and the positioning effect is good. Furthermore, the ring beam formwork shell can be integrally cast, with the two side plates 11 and the connecting plate 12 being integral, further enhancing the overall structural strength and reducing manufacturing difficulty.
[0046] In some possible implementations, the connecting plate 12 is provided with a plurality of fixing holes 121, which are spaced apart sequentially along the length of the connecting plate 12. The fixing holes 121 allow fasteners to easily pass through the connecting plate 12 and connect to the wall panel. The fasteners can be one of expansion bolts, cement bolts, or wire rope clips. One end of the fastener passes through the fixing hole 121 and is fixedly connected to the wall panel, while the other end of the fastener is confined to the side of the connecting plate 12 away from the wall panel.
[0047] In some possible implementations, the width of the bottom groove 101 gradually increases from the bottom to the opening, thus guiding the installation of the ring beam membrane shell 1 onto the wall panel and providing a certain degree of automatic calibration and positioning, making the installation of the ring beam membrane shell 1 more convenient and the position more accurate. Similarly, the width of the top groove 102 gradually increases from the bottom to the opening, making it less likely for voids to form when concrete is injected into the top groove 102.
[0048] Example 1
[0049] like Figures 2 to 4 As shown, this embodiment provides a building structure, including an exterior wall panel 4, a ring beam formwork shell as described in Embodiment 1, and ring beam concrete. The ring beam formwork shell is fitted onto the upper edge of the exterior wall panel 4 through a bottom groove 101, and the ring beam concrete is filled in the top groove 102 of the ring beam formwork shell.
[0050] The building structure provided in this embodiment uses the ring beam formwork shell and the outer wall panel 4 from Embodiment 1 to construct the ring beam. Adhesive mortar is applied to the upper part of the wall panel, and the ring beam formwork shell 1 is placed on the wall panel, with its upper end embedded in the bottom groove 101 of the ring beam formwork shell 1. Connectors are then used to connect the ring beam formwork shell 1 to the wall panel, and ring beam concrete is injected into the top groove 102. The width of the bottom groove 101 of the ring beam formwork shell is adapted to the width of the wall to which it is installed. When the ring beam formwork shell 1 is installed on the wall panel, the upper part of the wall panel is embedded in the bottom groove 101, which acts as a limit, allowing for quick installation of the ring beam formwork shell 1 onto the wall panel without the need for calibration tools, and ensuring accurate alignment between the ring beam formwork shell 1 and the wall panel. This significantly saves manpower, resources, and time, and improves the quality and aesthetics of the finished ring beam.
[0051] In some possible implementations, the exterior wall panel 4 has a main wall body 41 and a protruding strip 42 located on top of the main wall body 41. The width of the protruding strip 42 is less than the thickness of the main wall body 41, and the protruding strip 42 is embedded in the bottom groove 101. With the protruding strip 42, whose thickness is less than that of the main wall body 41, provided on the top of the exterior wall panel 4, after the bottom groove 101 of the ring beam membrane shell 1 is fitted onto the protruding strip 42, the outer surfaces of the side plates 11 on both sides of the ring beam membrane shell 1 can be in the same plane as the outer surface of the exterior wall panel 4. This results in an aesthetically pleasing structure and facilitates subsequent wall decoration.
[0052] In some possible implementations, adhesive sand is filled between the protruding strip 42 and the inner wall of the bottom groove 101. The adhesive sand provides initial fixation during the initial bonding process between the ring beam membrane shell 1 and the wall panel, preventing misalignment such as tilting or sliding during the installation of the ring beam membrane shell 1. This makes the installation of the ring beam membrane shell 1 more convenient.
[0053] In some possible implementations, one end of the fastener passes through the connecting plate 12 of the ring beam's non-removable formwork and is connected to the outer wall panel 4, while the other end of the fastener is confined to the side of the connecting plate 12 near the top groove 102. After the fastener passes through the fixing hole 121, it passes through the adhesive sand before being connected to the wall panel. During the process of the fastener passing through the adhesive sand, some of the squeezed adhesive sand will be discharged from the fixing hole 121.
[0054] In some possible implementations, the building structure includes reinforcing ring beams housed within the top recess 102, with the reinforcing ring beams encased in concrete. The inclusion of reinforcing ring beams within the concrete of the ring beams enhances their strength.
[0055] In some possible implementations, the exterior wall panel 4 includes a foamed cement insulation layer 401 and an outer protective layer 402. The outer protective layer 402 is disposed on both sides of the foamed cement insulation layer 401 along its thickness direction, and a steel mesh is disposed between the outer protective layer 402 and the foamed cement insulation layer 401.
[0056] 401 foamed cement insulation layer provides thermal insulation and heat preservation. Made with foamed cement insulation boards, it has a low thermal conductivity, effectively preventing heat transfer. In summer, it blocks high outdoor temperatures from entering the room, and in winter, it reduces heat loss, maintaining a stable room temperature. Furthermore, it is fireproof and waterproof; the material itself is non-combustible and has excellent waterproof performance, making it suitable for use as a firebreak and meeting building fire safety requirements. Additionally, it reduces the load on walls; its low density allows for thinner walls, increasing usable indoor space and avoiding the heaviness of traditional brick walls.
[0057] The outer protective layer, 402, covers the outside of the insulation layer to prevent external physical damage (such as impacts and rain erosion), extending the service life of the insulation layer. It also enhances stability, improving the overall strength of the wall and reducing the risk of cracking after bonding with the insulation layer.
[0058] Steel mesh is a reinforcing structure; embedding steel mesh into the wall enhances tensile strength and load-bearing capacity, preventing deformation. It can also reduce the risk of cracking by constraining the differences in thermal expansion and contraction between different materials.
[0059] The preferred embodiments disclosed above are merely illustrative of this application. The preferred embodiments do not exhaustively describe modifications and variations. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
