Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an independent supporting system of post-casting strip aluminum formwork uprights. Background Art

[0002] Post-cast strips are concrete strips set at corresponding positions of foundation slabs, walls and beams in accordance with design or construction specifications to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement. According to the "Concrete Structure Engineering Construction Code" GB50666, the formwork and support of the post-cast strips should be set independently, such as Figure 1 As shown, the current common practice is to set up full-height scaffolding in the post-casting joint, and keep it until the post-casting joint is closed and the concrete reaches the required strength and then remove it. However, for the post-casting joint location with a large basement, this method will cause a large amount of scaffolding material to be squeezed, which is not conducive to on-site turnover and difficult to carry out interspersed construction, which needs to be solved urgently. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the present application provides an independent support system of aluminum formwork uprights for post-cast strips, which is conducive to the interlaced construction of basements and reduces the backlog of basement materials.

[0007] A plurality of support plates are arranged along the length direction of the post-cast strip structure at the bottom of the formwork body, a plurality of telescopic support rods are vertically arranged at the bottom of each support plate, each telescopic support rod is respectively arranged at the bottom corner of the support plate, one end of the telescopic support rod is fixedly connected to the support plate and the other end is abutted against the ground.

[0008] By adopting the above technical scheme, under the telescopic action of the telescopic support rod, the support plate can move close to the formwork body in the vertical direction until it abuts against the formwork body, providing stable support for the formwork body, and forming an independent support system integrating the formwork body, the support plate and the telescopic support rod, completing the support of the post-cast strip structure part. Compared with the traditional post-cast strip independent support system, there is no cross bar between each component, which is convenient for the traffic organization of the basement. The basement can insert masonry, plastering and other construction processes in advance when the post-cast strip is not closed, saving time in the subsequent transportation of construction materials, and can reduce the backlog of basement materials, which is conducive to the interspersed construction of the basement.

[0009] In a preferred example, the present application can be further configured as follows: the support plate and the telescopic support rod are both made of aluminum.

[0014] By adopting the above technical solution, the telescopic function and the fixing function of the telescopic support rod can be realized through the sliding fit between the outer tube and the inner tube and the threaded connection through the fixing bolt, and the structure is simple and practical.

[0015] In a preferred example, the present application can be further configured as follows: a positioning column is provided at the bottom of the support plate at a position corresponding to the inner tube, and the positioning column is used for plugging and mating with the inner tube.

[0016] By adopting the above technical solution, a positioning column is provided, and the positioning column and the inner tube are plugged in and cooperated with each other, which can assist the staff to accurately install the telescopic support rod.

[0017] In a preferred example, the present application can be further configured as follows: a connecting piece is fixedly connected to the bottom of the support plate at a position corresponding to the telescopic support rod, and the connecting piece is fixedly connected between the telescopic support rod and the support plate.

[0018] By adopting the above technical solution and providing a connecting piece, the contact area between the telescopic support rod and the support plate can be increased, so as to further improve the supporting effect of the telescopic support rod.

[0019] In a preferred example, the present application can be further configured as follows: a mounting groove is opened at the bottom of the support plate, the mounting groove is rectangular in shape, the number of the telescopic support rods is four, and the four telescopic support rods are respectively fixedly connected to the corners of the bottom wall of the mounting groove.

[0020] By adopting the above technical solution, the telescopic support rod is arranged at the corner in the rectangular installation groove, which can wrap and store the telescopic support rod, thereby reducing the possibility of the telescopic support rod detaching from the support plate.

[0022] By adopting the above technical solution, the wooden formwork is low-cost and meets environmental protection requirements, and can be cut and processed at any time according to the size requirements of the basement project.

[0023] In a preferred example, the present application can be further configured as follows: the construction process of the template body includes:

[0024] S1. Install the formwork body, support plate and telescopic support rod at the post-casting strip to be poured;

[0025] S2, pouring the post-casting strip structure;

[0026] S3. When the concrete strength reaches the strength design value for removing the formwork, the portion of the formwork between the post-casting strip structure and several support plates is retained, and the remaining portion is removed by cutting.

[0027] By adopting the above technical solution, the construction process of the early dismantling system of the post-cast strip can be adapted, and after the dismantling turnover of the formwork body is completed, part of the formwork body, support plates and telescopic support rods can continue to serve as a support system to support the post-cast strip part until the structure expands and contracts and the building settlement stabilizes.

Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0037] It should be noted that the terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0038] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0039] The following describes an independent support system for post-cast aluminum formwork poles of the present application with reference to the accompanying drawings.

[0040] like Figure 2 As shown, the post-casting strip aluminum formwork stand independent support system includes a post-casting strip structure 1, a formwork body 2 and a plurality of support plates 3, the formwork body 2 is arranged at the bottom of the post-casting strip structure 1, wherein the support plates 3 and the telescopic support rods 4 are both made of aluminum, and the support plates 3 and the telescopic support rods 4 made of aluminum are light and easy to carry, durable and not easy to rust, and can be reused, which can greatly save construction costs and is suitable for this working condition;

[0041] In order to achieve the supporting effect on the formwork body 2, a number of support plates 3 are arranged at the bottom of the formwork body 2 along the length direction of the post-cast strip structure 1, and a number of telescopic support rods 4 are vertically arranged at the bottom of each support plate 3, and each telescopic support rod 4 is respectively arranged at the bottom corner of the support plate 3, one end of the telescopic support rod 4 is fixedly connected to the support plate 3 and the other end is abutted against the ground. Under the telescopic effect of the telescopic support rod 4, the support plate 3 can move close to the formwork body 2 in the vertical direction until it abuts against the formwork body 2, providing a stable supporting effect for the formwork body 2, and forming an independent supporting system integrating the formwork body 2, the support plate 3 and the telescopic support rod 4, completing the support of part of the post-cast strip structure 1. Compared with the traditional post-cast strip independent support system, there is no cross bar between each component, which is convenient for the basement traffic organization. The basement can be inserted into the masonry, plastering and other construction processes in advance when the post-cast strip is not closed, saving time in the subsequent transportation of construction materials, and can reduce the backlog of basement materials, which is conducive to the interspersed construction of the basement.

[0042] It should be noted that if Figure 2 and Figure 3 As shown, the post-cast strip structure 1 includes a structural beam 11 and a structural plate 12 in the beam-slab structure, and the formwork body 2 is a beam side formwork and a beam bottom formwork when corresponding to the structural beam 11, and is a plate bottom formwork when corresponding to the structural plate 12. In this embodiment, the support plates 3 at corresponding positions respectively abut against the beam bottom formwork and the plate bottom formwork.

[0043] Among them, the size of the support plate 3 is 65*250*400mm. For the support of the bottom formwork of the post-cast strip beam, the support plate 3 of this size can be adapted to most of the beam widths of the basement (the beam width of the basement is roughly 400mm-600mm), thereby supporting the construction of the early dismantling system of the post-cast strip.

[0044] In addition, if Figure 2 As shown, the telescopic support rod 4 includes an inner tube 41 and an outer tube 42. The inner tube 41 is located directly above the outer tube 42 and is slidably matched with the outer tube 42. A plurality of first threaded holes 5 are arranged on the outer side of the inner tube 41 along its own height direction, and a second threaded hole 6 is opened on the outer side of the outer tube 42. The outer tube 42 is provided with a fixing bolt 7. When the second threaded hole 6 is directly opposite to any first threaded hole 5, the fixing bolt 7 is used to simultaneously threadably match with the first threaded hole 5 and the second threaded hole 6. Under the action of the sliding match between the outer tube 42 and the inner tube 41 and the threaded connection through the fixing bolt 7, the telescopic function and the fixing function of the telescopic support rod 4 can be realized, and the structure is simple and practical.

[0045] Furthermore, if Figure 4 As shown, a positioning column 8 is provided at a position corresponding to the inner tube 41 at the bottom of the support plate 3, and the positioning column 8 is used to be plugged in with the inner tube 41. By providing the positioning column 8, under the action of the plug-in cooperation between the positioning column 8 and the inner tube 41, the staff only needs to align the inner tube 41 with the positioning column 8 and insert it to complete the installation of the telescopic support rod 4, which can assist the staff to accurately install the telescopic support rod 4.

[0046] In addition, a connecting piece 9 is fixedly connected to the position of the telescopic support rod 4 at the bottom of the support plate 3. Usually, the connecting piece 9 can be fixedly connected between the telescopic support rod 4 and the support plate 3 by welding. By setting the connecting piece 9, the contact area between the telescopic support rod 4 and the support plate 3 can be increased to further improve the supporting effect of the telescopic support rod 4.

[0047] Furthermore, the connecting piece 9 is an aluminum sheet with a size of 6*60*80 mm. The connecting piece 9 with this size can meet the support and bearing requirements of the aluminum mold support system.

[0048] like Figure 2 and Figure 4 As shown, a mounting groove 10 is opened at the bottom of the support plate 3, and the shape of the mounting groove 10 is rectangular. There are four telescopic support rods 4, and the four telescopic support rods 4 are respectively fixedly connected to the corners of the bottom wall of the mounting groove 10. By arranging the telescopic support rods 4 at the corners in the rectangular mounting groove 10, the telescopic support rods 4 can be wrapped and stored, thereby reducing the possibility of the telescopic support rods 4 detaching from the support plate 3.

[0049] In this embodiment, the formwork body 2 is made of wood. Wooden formwork is low in cost and meets environmental protection requirements, and can be cut and processed at any time according to the size requirements of the basement project.

[0050] Furthermore, in order to adapt to the construction process of the post-cast strip early removal system, the construction process of the template body 2 includes:

[0051] S1, install the formwork body 2, the support plate 3 and the telescopic support rod 4 at the post-casting zone to be poured;

[0052] S2, pouring post-casting strip structure 1;

[0053] S3. After the concrete strength reaches the designed strength value for removing the formwork, the portion of the formwork body 2 between the post-casting strip structure 1 and the plurality of support plates 3 is retained, and the remaining portion is removed by cutting.

[0054] This process is adapted to the construction process of the early dismantling system of the post-cast strip, and after the dismantling turnover of the formwork body 2 is completed, part of the formwork body 2, the support plate 3 and the telescopic support rod 4 can continue to serve as a support system to support the post-cast strip part until the structure is expanded and the building settlement is stable.

[0055] It should be noted that in S3, when the formwork body 2 is dismantled, the beam side formwork should be directly dismantled and the beam bottom formwork should be retained. When the slab bottom formwork is dismantled, the portion of the slab bottom formwork located between the structural plate 12 and the support plate 3 should be retained. The remaining dismantled slab bottom formwork can be used as the slab bottom formwork of the next area, or as a fixed-length plate. In the early dismantling system, it is necessary to comprehensively consider factors such as the strength of the concrete, construction progress and safety, formulate a reasonable dismantling plan and time schedule, and ensure the quality and safety of the concrete structure, so necessary inspections and acceptance are required.

[0056] The implementation principle of an independent support system for aluminum formwork uprights of a post-cast strip in an embodiment of the present application is as follows: a formwork body 2 and a support plate 3 are installed at the post-cast strip to be cast; according to the height of the post-cast strip, each inner tube 41 is slid so that the inner tube 41 is close to the support plate 3 and aligned with the positioning column 8 for insertion and drives the support plate 3 to be pressed against the bottom of the formwork body 2; then, the fixing bolt 7 is threadedly matched with the first threaded hole 5 and the second threaded hole 6 to complete the fixed installation of the telescopic support rod 4, forming an independent support system integrating the formwork body 2, the support plate 3 and the telescopic support rod 4, completing the support of a part of the post-cast strip structure 1; compared with the traditional independent support system for post-cast strips, there is no cross bar between each component, which is convenient for the traffic organization of the basement; the basement can be inserted into masonry, plastering and other construction processes in advance when the post-cast strip is not closed, saving time in the subsequent transportation of construction materials, and can reduce the backlog of materials in the basement, which is conducive to the interspersed construction of the basement.

[0057] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
