Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an independent support system for a post-casting strip which is convenient for joint processing and staged support. Background Art

[0002] In traditional construction projects, post-cast joint construction is a crucial link. It is usually used to solve problems caused by excessive structural length, temperature changes or settlement differences. By reserving a certain space at the post-cast joint position, the secondary pouring of concrete is carried out after the main structure completes shrinkage or settlement stabilizes, thereby ensuring the integrity and stability of the building structure.

[0003] The existing scheme has the following defects. Since the position and shape of the post-cast strip may vary from project to project, construction workers need to design and make the template according to the specific situation, which is not only time-consuming and labor-intensive, but also increases the construction cost. At the same time, the installation and disassembly process of the template is also relatively complicated, often requiring a lot of manpower and time, and it cannot be flexibly supported independently, further extending the construction period. Secondly, traditional construction methods often make it difficult to ensure the quality of concrete at the post-cast strip, especially at the joints, which are prone to defects such as cracks and voids, which not only affects the aesthetics of the structure, but may also pose a potential threat to the integrity and durability of the structure. Summary of the invention

[0004] The present invention provides an independent support system for a post-cast strip which is convenient for joint processing and staged support, thereby solving the problem that independent support and flexible support cannot be achieved in the prior art.

[0005] The technical solution of the present invention is achieved in this way:

[0006] The invention discloses an independent support system for a post-cast strip, which is convenient for joint processing and phased support. The system comprises a fixed formwork, a movable formwork and an additional formwork respectively arranged on both sides of the post-cast strip. Before the overall pouring operation, the fixed formwork is fixed on both sides of the post-cast strip by a bracket. A movable formwork is arranged on one side of the fixed formwork close to the post-cast strip. An additional formwork is fixed above the movable formwork. The additional formwork is connected to the post-cast strip. The additional formwork enables the solidified concrete to form a tongue and groove connected to the post-cast strip. A connecting formwork is arranged below the post-cast strip. When the movable formwork and the additional formwork are removed, the two ends of the connecting formwork are respectively abutted against the fixed formwork on both sides of the post-cast strip.

[0007] Furthermore, the width of the fixed template is 300 mm, the width of the movable template is 200 mm, and the width of the additional template is 100 mm. By accurately calculating the template size, the space on the construction site can be used more effectively, reducing unnecessary material accumulation and transportation costs.

[0008] Furthermore, the support comprises a vertical pole, a top support and a square wood, wherein the top support is fixed to the top surface of the vertical pole, and the top support is abutted against the bottom surface of the fixed template through the square wood. The support structure makes the installation and disassembly process simple and fast, improves the construction efficiency and shortens the construction period.

[0009] A method for using an independent support system for a post-casting strip that is convenient for joint processing and phased support installation comprises the following steps:

[0010] Step 1: Before the overall operation, first fix the fixed formwork under the concrete through the bracket;

[0011] Step 2: Build movable formwork, additional formwork and baffles in sequence, so that the concrete layers on both sides of the post-casting strip solidify and form a tongue and groove at the bottom;

[0012] Step 3: When it is necessary to pour the post-casting strip, remove the movable formwork, additional formwork and baffle, place the connecting formwork between the fixed formworks through the support frame, and then start the pouring operation.

[0013] The beneficial effects that this technical solution can produce.

[0014] The present invention can greatly simplify the preparation steps of post-casting belt construction through the combination of pre-set fixed templates, movable templates and additional templates, so that the installation and removal of the templates are faster, thereby shortening the construction period. In the actual construction process, the post-casting belt construction around the main building can give priority to supporting the frame on one side of the main building, and the other side can choose the erection time according to the actual progress of the project, so as to realize the erection in batches and the later joint, so as to solve the problem of asynchronous construction on both sides of the post-casting belt, and the independently supported fixed template can be independently topped after the large-scale removal of the bottom membrane of the main building, without the need for secondary topping, reducing the disturbance to the completed main body, and the post-casting belt construction in the middle of the garage can be supported on both sides at the same time, both of which can achieve the effect of independent support, which is helpful to optimize the construction sequence, reduce unnecessary waiting time, thereby improving construction efficiency, and better utilizing construction resources and manpower. The additional template allows the solidified concrete to form a tongue and groove at the post-casting belt, which is helpful to better merge with the new concrete during subsequent pouring, and reduces the defects at the joints, which not only improves the aesthetics of the joints, but also helps to maintain the integrity and durability of the structure.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of this embodiment, it is necessary to understand that the terms "center, longitudinal, lateral, up, down, front, back, left, right, vertical, horizontal, top, bottom, inside, outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the invention.

[0024] like Figure 1-4 As shown, an embodiment of the present invention provides an independent support system for a post-cast strip that is convenient for joint processing and staged support, including a fixed formwork 1, a movable formwork 2 and an additional formwork 3 respectively arranged on both sides of the post-cast strip. Before the overall pouring operation, the fixed formwork 1 is fixed to both sides of the post-cast strip by a bracket, a movable formwork 2 is provided on the side of the fixed formwork 1 close to the post-cast strip, an additional formwork 3 is fixed above the movable formwork 2, and the additional formwork 3 is connected to the post-cast strip. The additional formwork 3 enables the solidified concrete to form a tongue and groove 4 connected to the post-cast strip, and a connecting formwork 5 is provided below the post-cast strip. When the movable formwork 2 and the additional formwork 3 are removed, the two ends of the connecting formwork 5 are respectively abutted against the fixed formwork 1 on both sides of the post-cast strip.

[0025] Before the overall operation, the fixed formwork 1 is first fixed to the bottom of the concrete through a bracket, and the movable formwork 2, additional formwork 3 and baffle are set up through the full-floor scaffolding. The additional formwork 3 forms a tongue and groove 4 at the bottom after the concrete on both sides of the post-casting strip solidifies. When it is necessary to cast the post-casting strip, it is only necessary to remove the additional formwork 3 and the movable formwork 2 together when dismantling the full-floor scaffolding, and the fixed formwork 1 is retained through an independent bracket. Supporting the fixed formwork 1 through an independent bracket can prevent the concrete from bending, deforming, or even cracking. In the later casting of the post-casting strip, it is only necessary to re-erect a row of columns to support the connecting formwork 5, which reduces the complexity of the later return to the top, template installation, adjustment and disassembly, thereby improving the construction efficiency, while reducing the risk of damaging the concrete surface due to the age, improper template installation or removal, and can also effectively prevent the template from displacement or deformation due to concrete pressure or construction vibration during the casting process. The fixed template 1 can be used to limit the connection template 5. At the same time, the flat connection template 5 can make the joints of new and old concrete on the same straight line, thereby solving the problem that independent supports cannot be quickly positioned and installed, and making the joints beautiful and straight.

[0026] like Figure 5 As shown, in the actual construction process, the construction of the post-cast strip around the main building can give priority to supporting the frame on one side of the main building, and the erection time of the other side can be selected according to the actual progress of the project, so as to realize phased erection and later combination, and solve the problem of asynchronous construction on both sides of the post-cast strip. In addition, the independently supported fixed formwork can be independently installed on top after the large-scale removal of the bottom membrane of the main building, without the need for secondary return to the top, thus reducing the disturbance to the completed main body. When constructing the post-cast strip in the middle of the garage, both sides can be supported at the same time. Both can achieve the effect of independent support, which is helpful to optimize the construction sequence, reduce unnecessary waiting time, thereby improving construction efficiency, and making better use of construction resources and manpower.

[0027] The width of the fixed template 1 is 300 mm, the width of the movable template 2 is 200 mm, and the width of the additional template 3 is 100 mm. By setting specific sizes, these templates can be more easily standardized and modularized, and also promote the interchangeability between templates, so that the templates can be quickly replaced or adjusted when necessary, and because the template size is fixed and easy to identify, construction workers can assemble and disassemble the template faster, reducing installation time.

[0028] like Figure 1-4As shown, the support includes a vertical pole 6, a top support and a square wood 7. The top support is fixed to the top surface of the vertical pole 6, and the top support is against the bottom surface of the fixed formwork 1 through the square wood 7. The vertical pole 6, as the vertical support part of the support, can provide vertical bearing capacity to ensure the stability of the entire support structure. The square wood 7, as a horizontal connecting piece, not only enhances the lateral stability of the support, but also effectively disperses the load to prevent structural damage caused by local overload. The top support is used to adjust the height of the support and ensure close contact between the upper structure and the support, thereby improving the stability of the overall structure.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
