Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically a building steel formwork. Background Technology

[0002] To address the shortcomings of existing technologies, this utility model provides a steel formwork for construction, solving the problems mentioned in the background section.

[0003] Steel formwork is a steel template used for concrete pouring and shaping. Besides steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects due to its reusability and aesthetically pleasing concrete pouring results. Steel formwork can replace wooden formwork, significantly reducing the pressure on pore water and air bubbles in the concrete compared to traditional formwork made of wood, plywood, or steel plates. After the concrete is poured and shaped using steel formwork, an ideal rough interface is formed, eliminating the need for roughing work before proceeding to the next construction step. It can be placed before or after the installation of reinforcing bars; if placed before the reinforcement, placement and installation are convenient and simple. The concrete pouring process can be visually monitored, reducing the risk of voids and honeycomb structures. With social development, the application of recyclable modular steel formwork is becoming increasingly widespread.

[0004] A search revealed a recyclable modular steel formwork for construction, application number 202221331104.7. The formwork includes a steel formwork body, a connecting frame, and disposable thin plates. The connecting frame is fixedly connected to the front end of the steel formwork body. Limiting sleeves are fixedly connected to the upper and right side walls of the connecting frame, and connecting sleeves are fixedly connected to the bottom and left side walls of the connecting frame. Limiting sleeves are fitted onto the connecting sleeves, and limiting grooves are formed inside the limiting sleeves. A connecting plate is slidably connected within the limiting grooves. A threaded rod is fixedly connected to one end of the connecting plate near the connecting sleeve, and the threaded rod is rotatably connected within the threaded grooves. This invention facilitates the rapid assembly and disassembly of two steel formwork bodies, increasing the effectiveness of the device and solving the problem of not being able to change the size of the device according to different situations during use.

[0005] In the above technical solution, when the template bodies are spliced ​​together, the threaded rod drives the connecting rod to move and insert into the corresponding connecting sleeve to complete the fixed connection during the splicing of adjacent templates. However, the environment in which building templates are used contains a large amount of dust, sand and solid particles and other debris. Even during the concrete pouring process, a small amount of debris may drip onto the outside of the template, which has a significant impact on the fit between the threaded rod and the threaded groove, resulting in poor operation and, in severe cases, rendering the template unusable.

[0023] 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.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in one embodiment of this utility model, a building steel formwork includes a plate 1, a reinforcing frame 2, a connecting seat 3, and a connecting component 4. The reinforcing frame 2 is fixedly connected to one side of the plate 1, enhancing the strength of the plate 1 and forming a stable connecting frame on the plate 1. This allows for the stable connection of adjacent formwork sections during assembly. The reinforcing frame 2 also includes connectors and support rods that cooperate with the steel pipe frame. The connection between the formwork and the steel pipe frame, as well as the supporting and reinforcing components, are all existing known and publicly disclosed technologies, and will not be described in detail here. They are also not shown in the accompanying drawings of this application. These components are mainly used to connect the formwork and the steel pipe frame. The pipe frame is connected together to ensure stable support for the formwork, thus enabling concrete pouring. A connecting seat 3 is fixedly connected to the reinforced frame 2, and the connecting seats 3 corresponding to the splicing edges of two adjacent plates 1 are detachably connected by a connecting component 4. By using the cooperation of the connecting seats 3 and the connecting component 4, the spliced ​​and combined formwork is stably connected together, completing the splicing and combination of the formwork. The connecting rod 401 of the connecting component 4 is inserted into the insertion sleeve 301, and an abutting plate 402 is inserted into the connecting rod 401. The abutting plate 402 is used to limit and fix the connecting rod 401 to the insertion sleeve 301, completing the stable connection between two adjacent connecting seats 3.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, connecting seats 3 are provided on all four sides of the reinforcing frame 2, and the plug sleeve 301 is installed through the connecting seats 3, so as to form a stable connecting component on the reinforcing frame 2. When the templates are spliced ​​together, it cooperates with the connecting component 4 to stably connect one side of the splicing of two adjacent templates together, thus completing the splicing of the templates. The plug sleeve 301 has a limiting groove 302 at one end facing the middle part of the plate 1. The limiting groove 302 and the abutment The contact plate 402 is designed to fit together with the limiting slot 302, the width of which is slightly larger than the thickness of the contact plate 402. This allows the vertical edge of the contact plate 402 to slide smoothly up and down in the limiting slot 302. The limiting slot 302 is used to improve the stability of the fit between the plug sleeve 301 and the contact plate 402, thus ensuring that when the contact plate 402 is struck, it can only move on a horizontal plane parallel to the template, and will not cause the connecting rod 401 to rotate on the plug sleeve 301, ensuring stable use.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, the insertion groove 4011 is through-cut on the connecting rod 401. The side of the insertion groove 4011 facing the middle part of the connecting rod 401 is set as a vertical groove side, and the side of the insertion groove 4011 facing the end of the connecting rod 401 is inclined as an inclined abutment surface 4012. The insertion groove 4011 is configured to cooperate with the abutment plate 402, so that the abutment plate 402 can be smoothly inserted into the insertion groove 4011, forming a stable limiting and blocking component on the connecting rod 401, preventing the connecting rod 401 from sliding off the insertion sleeve 301 of the connecting seat 3, thereby stably connecting the two connecting seats 3 together, completing the stable connection of the template splicing edge, and completing the splicing combination between templates;

[0028] The abutment plate 402 is designed to be wider at the top and narrower at the bottom. The lower end of the abutment plate 402 is designed as an arc-shaped end 4021, which facilitates the smooth insertion of the abutment plate 402 into the insertion slot 4011 of the connecting rod 401, allowing the two to fit together smoothly for use. One side of the abutment plate 402 is designed as a vertical plate edge, and the other side of the abutment plate 402 is designed as an inclined plate edge 4022. The inclined plate edge 4022 has the same inclination angle as the inclined abutment surface 4012. The vertical plate edge and the vertical groove edge are slidably connected, and the inclined plate edge 4022 is slidably connected to the inclined contact surface 4012. This allows the contact plate 402 to slide smoothly in the insertion groove 4011 when it is struck. As the contact plate 402 continues to penetrate deeper into the insertion groove 4011, the inclined plate edge 4022 pushes against the inclined contact surface 4012, ensuring that the vertical plate edge of the contact plate 402 is tightly against the end of the insertion sleeve 301.

[0029] The thickness of the contact plate 402 is slightly smaller than the width of the insertion slot 4011, ensuring that the contact plate 4092 can be smoothly inserted into the insertion slot 4011 and ensuring smooth use.

[0030] When assembling templates during use, the edges of two adjacent templates are brought together and the corresponding connecting seats 3 are aligned. Then, the connecting rod 401 is inserted into the insertion sleeve 301 of the connecting seat 3. Next, the abutting plate 402 is inserted into the insertion groove 4011 on the connecting rod 401. Then, the wider end of the abutting plate 401 is struck with a hammer or other auxiliary tool. With the strike, the inclined edge 4022 of the abutting plate 401 slides on the inclined abutting surface 4012 on one side of the insertion groove 4011. At the same time, during the sliding process, the connecting rod 401 is pushed against it, so that the other side of the abutting plate 402 is tightly pressed against the connecting seat 3, thereby completing the stable connection between the two connecting seats 3, thus achieving a stable assembly of templates and ensuring stable use in the future.

[0031] When disassembling the template, simply use a hammer or other auxiliary tools to tap the arc-shaped end 4021 of the contact plate 401 to separate the contact plate 402 from the connecting rod 401. Then, pull the connecting rod 401 out of the plug sleeve 301 and finally remove the template.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
