Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, specifically to a post-cast strip structure for beams. Background Technology

[0002] Currently, in the construction industry, in order to ensure the integrity and durability of buildings, especially in ultra-long structures or large-volume concrete structures, expansion joints, settlement joints and temperature joints are usually set in different parts of the structure. These gaps are finally sealed by reserving post-pouring strips during the construction stage.

[0003] For example, Chinese patent (publication number: CN206205200U) discloses a post-cast strip structure for an exterior wall, including a left wall, a right wall, and a post-cast strip. A precast wall panel is provided on the outer side of the post-cast strip. A tie rod is provided on the side of the precast wall panel facing the post-cast strip. A strip-shaped connecting block is provided at the position corresponding to each tie rod on the side of the post-cast strip away from the precast wall panel. The end of the tie rod away from the precast wall panel passes through the strip-shaped connecting block and extends out of the strip-shaped connecting block. A locking nut is threaded onto the end of the tie rod away from the precast wall panel. A waterproof coating layer is applied to the side of the precast wall panel facing away from the post-cast strip. A strip-shaped through groove is opened at both ends of the side of the precast wall panel facing the post-cast strip. A sealing strip is embedded in the inner edge of the strip-shaped through groove. The top surface of the sealing strip extends out of the groove opening. This utility model has a simple structure, is easy to construct, has better sealing performance for the wall, better waterproof effect, can avoid the adverse effects of water seepage on the post-cast strip, and improves the quality of post-cast strip pouring.

[0004] However, this structure is not very adaptable. Because it uses precast wall panels and lock nuts for installation, the size of the post-cast strip may vary on actual construction sites, making it difficult to guarantee the best sealing effect on each post-cast strip. Therefore, a beam post-cast strip structure is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a beam post-cast strip structure, which has the advantage of strong adaptability and solves the problem of poor adaptability of post-cast strip structures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a post-cast strip structure for beams, including a base layer, on which two crossbeams penetrating the base layer are fixed, a buffer groove is provided on the top of the base layer, and two stabilizing grooves are provided on the top of the base layer, the two crossbeams penetrating the base layer through the two stabilizing grooves respectively, the buffer groove being connected to the two stabilizing grooves, a stabilizing layer for improving overall stability is provided on the inner bottom wall of the buffer groove, a reinforcing layer for adapting to different sizes is provided on the top of the stabilizing layer, and a surface layer for effectively protecting the interior is provided on the top of the reinforcing layer, the surface layer being flush with the top of the base layer;

[0007] The reinforcing layer includes multiple connecting components that interlock with each other. Each connecting component has two connecting slots on its outer side and two connecting blocks that are adapted to the connecting slots are fixed on its outer side. The multiple connecting components are interlocked with each other through the connecting slots and connecting blocks.

[0008] By adopting this technical solution, the reinforcement layer has good adaptability, and multiple connecting components can freely expand and contract, thereby further improving the overall adaptability to different environments.

[0009] Furthermore, the stabilizing layer includes a support layer and a filling layer, the filling layer being fixed to the bottom wall of the buffer groove, and the support layer being embedded within the filling layer.

[0010] By adopting this technical solution, the stabilizing layer can effectively improve the overall stability, providing a stable and reliable environment for the laying of the reinforcing layer and the surface layer.

[0011] Furthermore, the filling layer is concrete, and the supporting layer is a steel reinforcement skeleton.

[0012] By adopting this technical solution, the steel reinforcement cage is made of HRB400 grade threaded steel with a diameter of 16mm and the spacing is kept at about 15cm to meet the stress requirements. The steel reinforcement cage and concrete work together to fully improve the overall strength.

[0013] Furthermore, each of the connecting components includes a stabilizing block, four stabilizing rods, four telescopic springs, and four moving rods. The outer side of the stabilizing block is fixed to the four stabilizing rods, the inner walls of the four stabilizing rods are respectively fixed to the four telescopic springs, and the opposite sides of the four telescopic springs are respectively fixed to the four moving rods. Each moving rod extends to the outer side of the stabilizing rod.

[0014] By adopting this technical solution, the stabilizing rod can freely extend and retract, thereby enabling the connecting components to be freely adjusted.

[0015] Furthermore, each of the connecting components is cross-shaped, and the two opposite sides of the two moving rods on each connecting component are fixed to the connecting block, and the two connecting slots are respectively located on the opposite sides of the other two moving rods.

[0016] By adopting this technical solution, the connection blocks and connection slots work together to facilitate the installation of multiple connection components. The installation method is simple and can effectively improve construction efficiency.

[0017] Furthermore, the surface layer includes two connecting layers and a protective layer. The opposite sides of the two connecting layers are respectively fixed to two crossbeams, and the two connecting layers are fixed to the protective layer.

[0018] By adopting this technical solution, the connecting layer plays a certain sealing role, and the protective layer, together with the connecting layer, can play a good protective role, reducing the intrusion of moisture into the interior.

[0019] Furthermore, each of the connecting layers is an elastic sealing tape, and the protective layer is cement.

[0020] By adopting this technical solution, the elastic sealing tape is made of EPDM, which has good elasticity and weather resistance, and is about 30cm wide to ensure sufficient sealing area.

[0021] Furthermore, the top nozzle of the cement has a waterproof layer, which is flush with the top of the base layer.

[0022] By adopting this technical solution, the waterproof layer plays a waterproof role. Through the combination of the waterproof layer and the protective layer, relatively good waterproof and protective properties can be achieved.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 In this embodiment, a post-cast strip structure for a beam includes a base layer 1. Two crossbeams 2 are fixed on the base layer 1, penetrating the base layer 1. The base layer 1 provides connection stability for the crossbeams 2 and provides the necessary environment for the stabilizing layer 3, the reinforcing layer 4, and the surface layer 5. A buffer groove is provided on the top of the base layer 1, and two stabilizing grooves are provided on the top of the base layer 1. The two crossbeams 2 penetrate the base layer 1 through the two stabilizing grooves respectively. The buffer groove is connected to the two stabilizing grooves. The inner bottom wall of the buffer groove is provided with a stabilizing layer 3 to improve overall stability. The top of the stabilizing layer 3 is provided with a reinforcing layer 4 that can adapt to different sizes. The top of the reinforcing layer 4 is provided with a surface layer 5 that effectively protects the interior. The surface layer 5 is flush with the top of the base layer 1. The top nozzle of the cement has a waterproof layer, which is flush with the top of the base layer 1.

[0031] In addition, the stabilizing layer 3 includes a support layer 301 and a filling layer 302. The filling layer 302 is fixed to the bottom wall of the buffer groove. The support layer 301 is embedded in the filling layer 302. During installation, the support layer 301 needs to be installed on the bottom wall of the installation groove first, then the reinforcing layer 4 is welded to the support layer 301, and finally the filling layer 302 is poured. The filling layer 302 flows to the support layer 301 through the gaps in the reinforcing layer 4.

[0032] It should be further explained that the infill layer 302 is concrete, and the support layer 301 is a steel reinforcement cage. Concrete itself has high compressive strength and can withstand pressure from all directions well, while steel reinforcement has excellent tensile strength. When the structure is subjected to tensile force, the steel reinforcement can bear the tensile force and prevent the structure from being pulled apart or deformed excessively. When the steel reinforcement cage and concrete are combined, they can complement each other. When bearing load, the concrete bears the compressive force and the steel reinforcement bears the tensile force. Together, they greatly improve the load-bearing capacity of the entire structure. At the same time, the concrete wraps around the steel reinforcement cage, forming a relatively dense protective structure that can prevent moisture, oxygen, corrosive chemicals and other substances in the external environment from directly contacting the steel reinforcement. The steel reinforcement cage can enhance the overall stability of the concrete structure and reduce the occurrence of concrete cracking and spalling caused by factors such as temperature changes and alternating wet and dry conditions, thereby better maintaining the integrity of the structure and ensuring its long-term normal use.

[0033] In this embodiment, the base layer 1 has good stability, providing good support for the beam 2 and the stabilizing layer 3, while the reinforcing layer 4 has good deformation capacity and can adapt to different usage environments.

[0034] Please refer to it again. Figure 1 and Figures 2 to 3 To effectively improve overall adaptability, the reinforcing layer 4 in this embodiment includes multiple connecting components 401, which are interlocked with each other. Each connecting component 401 has two connecting slots on its outer side, and two connecting blocks that are compatible with the connecting slots are fixed on its outer side. The multiple connecting components 401 are interlocked with each other through the connecting slots and connecting blocks. The interlocking of the connecting slots and connecting blocks facilitates the assembly of the reinforcing layer 4 by the workers. By adopting a modular assembly method, the construction process is simplified, and labor costs and technical difficulties are reduced.

[0035] It is known that each connecting component 401 includes a stabilizing block 4011, four stabilizing rods 4012, four telescopic springs 4013, and four moving rods 4014. The outer side of the stabilizing block 4011 is fixed to the four stabilizing rods 4012, the inner walls of the four stabilizing rods 4012 are respectively fixed to the four telescopic springs 4013, and the opposite sides of the four telescopic springs 4013 are respectively fixed to the four moving rods 4014. Each moving rod 4014 extends to the outer side of the stabilizing rod 4012. The telescopic springs 4013 can deform with the moving rods 4014. When multiple connecting components 401 are assembled, the elastic force on the multiple telescopic springs 4013 can provide a certain supporting force, so that the reinforcing layer 4 has a certain supporting force around its perimeter.

[0036] It should be further explained that each connecting component 401 is cross-shaped. The cross shape can ensure that when multiple connecting components 401 are assembled, there is a relatively large gap, which facilitates the smooth flow of the filling layer 302. The two moving rods 4014 on each connecting component 401 are fixed to the connecting block on opposite sides, and the two connecting grooves are located on opposite sides of the other two moving rods 4014.

[0037] In addition, the surface layer 5 includes two connecting layers 501 and a protective layer 502. The opposite sides of the two connecting layers 501 are fixed to the two crossbeams 2 respectively, and the two connecting layers 501 are fixed to the protective layer 502. Each connecting layer 501 is an elastic sealing tape, and the protective layer 502 is cement. High-performance concrete can be further introduced to replace ordinary cement, and its excellent compressive and flexural properties can be used to improve the overall mechanical performance of the post-cast strip.

[0038] In this embodiment, the elastic sealing tape can be made of different materials, such as PVC and neoprene rubber, to adapt to specific chemical corrosion or high and low temperature conditions. The waterproof layer can play a certain waterproof role and, together with the protective layer 502, effectively protects the internal reinforcing layer 4.

[0039] Understandably, the advantages of the support layer 301, the filling layer 302, the connecting layer 501, and the multiple connecting components 401 construct a multi-layer composite system, which significantly improves the deformation capacity and load-bearing capacity of the structure. In actual construction, the connecting components 401 are easy to assemble and simple to use.

[0040] The working principle of the above embodiments is as follows:

[0041] According to the design plan, precise measurements and layout were conducted on-site to determine the position and dimensions of the post-pouring strip. Then, the support layer 301 was laid. Multiple connecting components 401 were then spliced ​​together according to the site size, and the bottom of the stabilizing block 4011 was welded to the support layer 301. After welding, the filling layer 302 was poured onto the connecting components 401. Since the connecting components 401 form a mesh after splicing, the filling layer 302 could be smoothly deposited onto the support layer 301. Then, the connecting layer 501 was used to bond the beam 2 and the reinforcing layer 4. Next, the protective layer 502 was laid. After the protective layer 502 solidified, a waterproof layer was sprayed on top of the protective layer 502 to complete the installation. Subsequent installation only requires periodic inspection to avoid quality degradation caused by wet-dry cycles. This structure is easy to install, reliable, and robust. It also simplifies the construction process, reduces labor costs and technical difficulty, and the reinforcing layer 4 has good deformation capacity, easily adapting to different shapes.
