[0002] In the construction of simply supported beams, the installation and dismantling of side formwork are crucial steps to ensure the quality of beam formation. Currently, the construction of side formwork for simply supported beams typically employs traditional fixed installation methods. After the concrete is poured and solidified, the side formwork is prone to sticking to the concrete surface due to factors such as adhesion, friction, and the wrapping force generated by the concrete's solidification shrinkage.
[0003] Once the side formwork adheres, construction workers often need to spend a lot of time and manpower using methods such as prying with crowbars and hammering to forcibly separate it. This is not only inefficient but may also damage the concrete surface, leading to quality problems such as chipped edges and surface cracks in the beam, seriously affecting the appearance and structural performance of the simply supported beam. In addition, forced separation may also damage the side formwork, shorten its service life, and increase construction costs. In view of this, this utility model proposes a movable construction device for the side formwork of a three-line parallel simply supported beam. Utility Model Content
[0004] The purpose of this invention is to address the problems in the background technology where the construction of side formwork for simply supported beams currently mostly adopts the traditional fixed installation method, which results in the side formwork easily sticking to the concrete surface after the concrete solidifies, leading to difficulties in disassembly, low construction efficiency, damage to the beam quality, shortened life of the side formwork, and increased costs.

[0032] Example
[0033] like Figure 1 As shown, the present invention proposes a movable construction device for side formwork of a three-line parallel simply supported beam, which includes a steel frame 1, a panel 2 fixedly connected to one side of the steel frame 1, and the panel 2 is used to shape the side of the concrete.
[0034] For further details, please refer to Figures 1 to 3 The aforementioned construction device includes a movable component 3 installed at the bottom of the steel frame 1, which is used to move the steel frame 1. The movable component 3 includes multiple sets of fixed plates 31 fixedly connected to the bottom of the steel frame 1. Two sets of side plates 32 are fixedly connected to the bottom of each fixed plate 31, and multiple sets of movable wheels 33 are rotatably connected between the two sets of side plates 32. The movable component 3 also includes two sets of tracks 34 fixedly installed below the steel frame 1, with the multiple sets of movable wheels 33 located on the two sets of tracks 34 respectively. The movement of the movable wheels 33 on the tracks 34 allows the steel frame 1 and the panel 2 to move, facilitating the movement of the panel 2 to the next position to support the side of the concrete after the concrete pouring and solidification at one location.
[0035] Furthermore, such as Figures 1 to 4As shown in the figure, the above construction device further comprises a positioning mechanism 4 arranged below the steel frame 1, and the positioning mechanism 4 is used for fixing the position of the steel frame 1. The positioning mechanism 4 comprises two sets of positioning plates 41 arranged below the steel frame 1, the tops of the two sets of positioning plates 41 are respectively and fixedly connected with a plurality of sets of mounting frames 42, the mounting frames 42 are arranged in a "∩" shape, and the mounting frames 42 are slidably connected to the bottom of the steel frame 1, so that when the steel frame 1 moves on the rail 34, the positioning plates 41 and the mounting frames 42 are driven to move synchronously. Meanwhile, when the panel 2 is far away from the concrete, it moves stably under the limiting effect of the mounting frames 42. A push rod motor 43 is installed on the top of the mounting frame 42, the output end of the push rod motor 43 penetrates through the mounting frame 42 and is fixedly connected with a sliding rod 44, the bottoms of the multiple sets of sliding rods 44 are jointly and fixedly connected with a positioning frame 45, and the push rod motor 43 drives the positioning frame 45 to move through the sliding rods 44. The positioning frame 45 is arranged in a "∩" shape, a fixing block 46 is arranged below the positioning frame 45, and the fixing block 46 is fixedly arranged, so that after the positioning frame 45 is clamped on the top of the fixing block 46, the friction force when the steel frame 1 moves is increased, and the steel frame 1 can be prevented from continuing to move. Meanwhile, with the "∩"-shaped arrangement, when the steel frame 1 and the panel 2 are far away from the concrete, the position of the fixing plate 31 is fixed. The outer ring of the sliding rod 44 is slidably sleeved with a sliding sleeve 47, the sliding sleeve 47 is fixedly connected in the positioning plate 41, and the sliding sleeve 47 is used for increasing the force bearing area of the outer ring of the sliding rod 44 and preventing the sliding rod 44 from being bent due to excessive force. A connecting plate 48 is fixedly connected between the two sets of positioning plates 41 to integrate the two sets of positioning plates 41, and when the steel frame 1 and the panel 2 need to be moved to be far away from the concrete, the positioning mechanism 4 serves as a reference.
[0036] Specifically, the above construction device further comprises a demolding assembly 5 installed at the bottom of the steel frame 1, and the demolding assembly 5 is used for driving the steel frame 1 and the panel 2 to be far away from the solidified concrete to realize the separation of the panel 2. The demolding assembly 5 comprises a threaded block 51 fixedly connected to the top of the connecting plate 48, and the position of the threaded block 51 is fixed. A threaded rod 52 is threadedly connected in the threaded block 51, and the threaded block 51 moves along its own length direction when rotating. A plurality of sets of connecting sleeves 53 are rotatably connected to the threaded rod 52, and the plurality of sets of connecting sleeves 53 are all fixedly connected with the steel frame 1, so that the threaded rod 52 keeps rotating in place relative to the steel frame 1, and when the threaded rod 52 moves, the steel frame 1 is driven to move synchronously through the connecting sleeves 53. A rotating handle 54 is installed at one end of the connecting sleeve 53, and the arrangement of the rotating handle 54 facilitates the rotation of the threaded rod 52.
[0037] Further, the above construction device further comprises a motor controller, and the multiple sets of push rod motors 43 are all electrically connected with the motor controller, so that the multiple sets of push rod motors 43 for controlling the same set of positioning frames 45 work synchronously and have the same telescopic distance, preventing structural damage caused by the difference in extension length.
[0038] In this embodiment, before concrete pouring, the device is moved to a designated position by the moving component 3. The fixed plate 31, side plate 32 and moving wheel 33 at the bottom of the steel frame 1 constitute the moving base. The moving wheel 33 rolls on the fixed track 34, thereby driving the steel frame 1 and panel 2 to move conveniently and accurately to the pouring position.
[0039] Once the device reaches the predetermined position, the push rod motor 43 is controlled by the motor controller. The push rod motor 43 drives the slide rod 44 to move the positioning frame 45 downward. When the positioning frame 45 is stuck on the top of the fixing block 46, a strong frictional force is formed, which effectively restricts the movement of the steel frame 1. At the same time, the mounting frame 42 is slidably connected to the bottom of the steel frame 1. When the panel 2 is away from the concrete, it is limited by the mounting frame 42, ensuring that the device is stably fixed and providing reliable support for concrete pouring.
[0040] After the concrete is poured and solidified, the demolding assembly 5 is used to separate the panel 2 from the concrete. Rotating the handle 54 causes the threaded rod 52 to rotate within the threaded block 51. Since the threaded block 51 is fixed in position, the threaded rod 52 moves along its own length during rotation, driving the steel frame 1 and panel 2 away from the solidified concrete via the connecting sleeve 53, thus achieving smooth separation of panel 2 from the concrete. After separation, the moving assembly 3 is used again to move the moving wheels 33 onto the track 34, moving the device to the next pouring position. The above positioning, pouring, and demolding process is repeated, efficiently completing the side formwork construction task of the three-line parallel simply supported beam.
[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
