Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering and construction casting templates, in particular to a civil engineering and construction casting template which is easy to assemble. Background Art

[0002] Building formwork is a temporary supporting structure, which is made according to the design requirements to shape the concrete structure and components into the specified position and geometric size, maintain its correct position, and bear the deadweight of the building formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality of concrete engineering and construction safety, speed up the construction progress and reduce the project cost. When conventional formwork is spliced, steel wire is mostly used to penetrate the adjacent overlapped formwork to achieve binding assembly. During the operation, workers need to tie and fix the steel wires at each position one by one, which is time-consuming and labor-intensive. Therefore, a civil engineering casting formwork that is easy to assemble is designed.

[0003] For example, Chinese patent CN215830001 U discloses a casting formwork for civil engineering and construction that is easy to assemble, including a supporting base plate, a baffle, a first formwork, a second formwork and a locking bolt, wherein the baffle is fixedly installed on the upper end of the supporting base plate, the first formwork is installed on the inner side of the baffle, and the second formwork is arranged on the side of the first formwork, which is used to be combined to form a closed casting frame; it also includes: an insertion port arranged on the side of the first formwork, a docking block is installed inside the insertion port; a guide column, fixedly installed on the lower end side of the supporting base plate, and the guide column is installed inside the limit seat; a connecting block, arranged on the outer side of the guide column, and a movable cross bar is connected to the side of the connecting block. The casting formwork for civil engineering and construction that is easy to assemble can improve the sealing of the frame formed by the overall casting formwork during concrete pouring after the mutual assembly is completed, so as to prevent the concrete from leaking.

[0025] See also Figure 2-3 In order to enhance the strength of the connection between the first template 1 and the second template 2, the support mechanism 3 in this embodiment includes four second articulated frames 308 respectively fixed on the left and right sides of the two first templates 1, and the four second articulated frames 308 are respectively hinged to four support plates 306 through four second hinge shafts, and an extension spring 309 is fixed inside the support plate 306, and a limit plate 310 slidably connected to the inside of the support plate 306 is fixed on the side of the extension spring 309 away from the second articulated frame 308, and an extension plate 303 is fixed on the side of the limit plate 310 away from the support plate 306, and one end of the extension plate 303 away from the limit plate 310 is rotatably connected to the first articulated frame 301 through the first hinge shaft, and mounting plates 302 are fixed on the left and right sides of the two second templates 2, and a slider 307 slidably connected to the inside of the mounting plate 302 is fixed on the side of the first articulated frame 301 close to the second template 2, and the support mechanism 3 is symmetrical up and down with the central axis of the second template 2 as the symmetry line.

[0026] The upper and lower surfaces of the mounting plate 302 are provided with sliding grooves for the sliding block 307 to slide and connect. The cross-section of the sliding block 307 is T-shaped.

[0031] It should be noted that the splitting assembly facilitates the connection of the first template 1, the second template 2 and the support mechanism 3 together through the cooperation of the mounting block 311, the movable plate 312, the connecting block 313, the fixed block 314, the pressing plate 315, the connecting block 316, the slide plate 317, the pushing block 318 and the return spring 319, and at the same time, it is convenient for the staff to easily remove the support mechanism 3 in the subsequent template disassembly work, thereby contacting the restrictions on the first template 1 and the second template 2.

[0032] The working principle of the above embodiment is:

[0033] (1) When installing the casting formwork, first fit the two first formworks 1 with the base plate 4 and fix them on the opposite sides of the two fixing plates 5 by screws. Then, insert the two ends of the two second formworks 2 into the two first formworks 1 respectively. When the positioning block 305 is inserted into the positioning groove, the second formwork 2 fits with the base plate 4 and completes the connection with the first formwork 1. Then, fix the four second hinged frames 308 on the left and right sides of the two first formworks 1 respectively. At the same time, fix a mounting plate 302 on the left and right sides of the two second formworks 2 respectively. Then, rotate the support plate 306 toward the nearest second formwork 2 through the second hinged frame 308. At the same time, pull the first hinged frame 301 toward the middle of the second formwork 2. The frame 301 drives the extension plate 303 to move together, and the extension plate 303 stretches the extension spring 309 through the limit plate 310, then the slider 307 on the first hinge frame 301 is inserted into the mounting plate 302, and the connecting block 313 on the first hinge frame 301 is inserted into the mounting block 311 to complete the fixation. The support mechanism 3 strengthens the support strength of the connection between the first template 1 and the second template 2 through the cooperation of the first hinge frame 301, the mounting plate 302, the extension plate 303, the support plate 306, the second hinge frame 308, the extension spring 309, the limit plate 310 and the mounting block 311, so that the second template 2 can disperse the impact force after being hit by the extension plate 303 and the support plate 306.

[0034] (2) When the first template 1 and the second template 2 need to be separated, the two pressing plates 315 on the left and right sides are pressed toward the middle respectively. The connecting block 316 moves together with the pressing plate 315 and pushes the pushing block 318 through the slide plate 317. The pushing block 318 pushes the fixing block 314 into the inside of the connecting block 313. At the same time, the fixing block 314 compresses the return spring 319 through the movable plate 312. Then, the first hinge frames 301 on the upper and lower sides are pulled to the upper and lower sides respectively, and the connecting block 313 is driven to separate from the mounting block 311. When the connecting block 313 is completely separated from the mounting block 311, the return spring 319 pushes the fixing block 314 into the inside of the connecting block 313 through the rebound force. The fixed block 314 is pushed out of the interior of the connecting block 313, and then the screws on the second hinged frame 308 and the mounting plate 302 are removed to complete the disassembly of the supporting mechanism 3. The disassembly components are conveniently connected together with the first template 1, the second template 2 and the supporting mechanism 3 through the cooperation of the mounting block 311, the movable plate 312, the connecting block 313, the fixed block 314, the pressing plate 315, the connecting block 316, the slide plate 317, the pushing block 318 and the reset spring 319. At the same time, it is convenient for the staff to easily remove the supporting mechanism 3 in the subsequent template disassembly work, thereby contacting the restrictions on the first template 1 and the second template 2.
