Description

Technical Field

[0001] The utility model relates to the technical field of assembled formwork, and more specifically, to an assembled beam-column node formwork. Background Art

[0002] In prefabricated buildings, the treatment of connection nodes after beams and columns are in place is crucial for ensuring structural stability. Prefabricated building components, such as beams and columns, are often prefabricated and assembled on-site. To ensure these prefabricated components form a stable and well-performing structure, the connection nodes are often joined with cast-in-place concrete. This connection method significantly improves the load-bearing capacity and seismic performance of the nodes by connecting and anchoring steel bars, combined with the strength and toughness of cast-in-place concrete.

[0003] However, during cast-in-place joint construction, the formwork at these joints becomes a crucial factor, impacting both construction speed and quality. Traditionally, wooden formwork frames are widely used for these joints due to their readily available materials and ease of construction. However, wooden formwork construction presents several challenges. First, wooden formwork is relatively complex to manufacture, particularly when working with complex shapes like arcs, requiring precise cutting and splicing. Second, wooden formwork is not easily reusable, requiring repair or replacement after each use, increasing construction costs.

[0004] The above shortcomings need to be improved. Summary of the Invention

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 and Figure 2 As shown, an assembled beam-column node formwork described in one embodiment of the utility model includes a formwork body 1, the model surface of the formwork body 1 includes an arc-shaped surface, and connecting parts 101 are respectively provided on the left and right sides of the outer facade of the formwork body 1, and the connecting parts 101 are detachably connected to the beam 2.

[0031] During construction, the template body 1 of appropriate size is selected according to the specific size and shape of the beam-column node, and the model surface of the prefabricated template body 1 matches the required curved surface to ensure the accuracy of the node casting. At the construction site, the template body 1 is quickly docked with the beam 2 through the connection part 101 on its facade, and fastened with bolts or other detachable connectors to ensure that the template is stable and does not shake. Subsequently, the steel bars are tied and then the concrete is poured. After the pouring is completed, when the concrete reaches a certain strength, the template can be easily removed and the construction of the next node can be carried out. The entire construction process does not require complicated on-site production and adjustment, which greatly improves the construction speed and accuracy.

[0032] In this embodiment, the formwork body 1 is prefabricated, with the mold surface matching the curved surface of the node. This effectively solves the problems of traditional wooden formwork, which is cumbersome to manufacture and difficult to produce curved formwork, thereby improving construction efficiency and the quality of node formation. Furthermore, the formwork is quickly connected to the crossbeam 2 via a detachable connection 101, making installation and removal simple and quick, reducing labor intensity and improving construction safety. Furthermore, the formwork material is highly reusable, reducing resource waste and lowering construction costs.

[0033] In practical applications, the model surface of the template body 1 can be a segment of an arc surface, or a combination of an arc surface and a plane, or a combination of multiple segments of an arc surface. The template body 1 can be spliced together to construct the required model surface as needed.

[0034] like Figure 1 and Figure 2 As shown, in a preferred embodiment, support portions 102 are respectively provided on the upper and lower sides of the facade of the template body 1 .

[0035] In this embodiment, the support portions 102 facilitate securing the upper and lower sides of the formwork, thereby improving the stability of the formwork during construction, effectively preventing deformation or displacement of the formwork during concrete pouring, and ensuring the accuracy of node formation. Furthermore, the support portions 102 enhance the structural strength of the formwork body 1, increasing its load-bearing capacity and extending its service life. Furthermore, the support portions 102 on the formwork body reduce the workload of constructing temporary support structures on-site, further improving construction efficiency and reducing construction costs.

[0036] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the outer facade of the formwork body 1 is provided with ribs 103 .

[0037] The ribs 103 include vertical ribs extending from the bottom to the top of the formwork body 1 .

[0038] The ribs 103 include transverse ribs, which extend from the left side to the right side of the template body 1 .

[0039] In this embodiment, the vertical ribs extend from the bottom to the top of the formwork, significantly enhancing the longitudinal stiffness of the formwork, effectively resisting the longitudinal pressure generated during the concrete pouring process, and ensuring the stability of the formwork in the vertical direction; at the same time, the arrangement of the transverse ribs from left to right strengthens the lateral strength of the formwork, further improving the overall structural strength of the formwork, and the criss-cross layout of the ribs 103 enables the formwork to maintain a stable shape when subjected to complex stresses, reducing the risk of deformation.

[0040] In addition, the ribs 103 optimize the stress distribution of the formwork, allowing the formwork to transfer and disperse the load more evenly, thereby improving the bearing capacity and safety of the formwork. This not only extends the service life of the formwork, but also reduces construction quality problems caused by formwork deformation.

[0041] In actual application, vertical ribs and transverse ribs can be set selectively, and the most appropriate template configuration can be selected according to the actual situation of the project to reduce unnecessary material consumption and cost expenditure.

[0042] like Figures 1 to 3 As shown, in a preferred embodiment, a connecting hole is opened on the connecting portion 101 , a screw 3 passing through the connecting hole is provided on the beam 2 , a nut is threadedly connected on the screw 3 , and a gasket 4 is provided between the nut and the connecting portion 101 .

[0043] The screw rod 3 is embedded in the cross beam 2 , and the embedded section of the screw rod 3 is provided with a bend, which forms an angle with the axis of the connecting section of the screw rod 3 .

[0044] In this embodiment, by embedding the screw 3 in the beam 2 and providing a bend in the embedded section, the connection point's pullout resistance and stability are enhanced. The angle between the bend and the axis of the screw 3's connecting section increases friction between the screw 3 and the beam 2 when subjected to force, preventing the screw 3 from loosening or being pulled out, thereby ensuring the stability and security of the connection between the formwork and the beam 2. Furthermore, the provision of a gasket 4 disperses pressure, protects the connection 101, and further extends the service life of the connection 101.

[0045] In practical applications, the screw rods 3 can be installed after the crossbeam 2 is formed. For example, if there are tension holes on the crossbeam 2, the screw rods 3 can be inserted into the tension holes, and washers 4 and nuts can be placed at both ends of the screw rods 3 to secure the module. Alternatively, the screw rods 3 can be expansion bolts, and holes can be drilled at the corresponding positions of the connection holes and the expansion bolts can be installed therein.

[0046] In a preferred embodiment, a sealing member is provided between the connecting portion 101 and the crossbeam 2 .

[0047] Specifically, the sealing member is double-sided foam adhesive.

[0048] In this embodiment, the double-sided foam adhesive has excellent sealing and adhesion properties, effectively filling the small gap between the connection portion 101 and the crossbeam 2, preventing concrete slurry or other liquids from seeping into the connection area during the pouring process, thereby keeping the connection portion 101 clean and dry. The seal prevents corrosion or failure of the connection caused by the intrusion of impurities, ensuring the quality of the concrete pour and the safety of the pouring process. In addition, the elasticity of the double-sided foam adhesive can also absorb and alleviate minor deformation caused by temperature changes or structural stress to a certain extent, further enhancing the stability and durability of the connection.

[0049] In actual application, a mounting groove may be provided on the connecting portion 101 , and a sealing member may be provided in the mounting groove. In this case, the sealing member may be a rubber sealing strip or a water-swelling waterstop strip.

[0050] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the template body 1 is an integrated structure.

[0051] The template body 1 is made of metal.

[0052] The template body 1 can be formed by machining, or by powder metallurgy, casting, 3D printing, etc.

[0053] In this embodiment, the integrated structure not only simplifies the formwork construction, reducing assembly components and connection points, thereby reducing complexity and error rates during construction, but also enhances the formwork's overall rigidity and stability, helping to withstand the tremendous pressure generated during concrete pouring. Furthermore, the choice of metal material gives the formwork excellent mechanical properties and durability, enabling it to withstand harsh construction environments and repeated use.

[0054] In addition, the template body 1 can be manufactured through a variety of molding technologies, such as machining, powder metallurgy, casting, 3D printing, etc. These molding technologies have high manufacturing accuracy and surface quality, and can also achieve precise molding of complex shapes and structures to meet the production needs of templates of different shapes.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
