Description

Technical Field

[0001] The present application relates to the field of casting formwork support, and in particular to a formwork joint device used for plane formwork support of concrete components. Background Art

[0002] The formwork joint device used for the plane formwork of concrete components has the main function of forming the required component shape and size when pouring concrete, and plays a role in supporting and maintaining the shape during the concrete hardening process;

[0003] When pouring concrete, a layer of anti-sticking film or waterproof breathable film is often laid on the formwork. The film can effectively isolate the concrete from the external environment, reduce water evaporation, and ensure that the concrete obtains sufficient water for hydration reaction in the initial and final setting stages, thereby improving the early strength and overall quality of the concrete. At the same time, laying a film on the formwork can also protect the formwork from direct erosion by concrete and extend the service life of the formwork;

[0004] In some small projects or traditional construction methods, manual film laying is usually adopted. Construction workers cut the film to a suitable size and then fit it to the inside of the wooden formwork. In construction sites with a high degree of industrialization and prefabrication, semi-automatic or fully automatic laying equipment may also be used to install the film. This type of equipment can efficiently and accurately lay the film on the inside of the formwork. Manual cutting and laying is inefficient and requires more manpower costs. Automatic laying equipment can lay the film efficiently, but since the side of the formwork is often a regular square, it is not convenient to fix the film on the formwork. If the film is not fixed well, it is easy to shift or fall off during the concrete pouring process, resulting in insufficient moisture maintenance in the local area, affecting the overall performance and strength development of the concrete. Secondly, if the film cannot be effectively fixed in the formwork, it may cause uneven moisture distribution on the surface of the concrete after pouring, cracks caused by too fast drying, and other quality problems. In order to solve the above problems, a formwork joint device for plane formwork of concrete components is proposed.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] The embodiment of the present application discloses a template jointing device for plane formwork of concrete components. Figure 1-6, a template jointing device for a plane formwork of a concrete member, comprising a base 1 for fixing a tongue-and-groove template 22, a fixing plate pin 21 for fixing a film on the tongue-and-groove template 22 and a pushing component for pushing the fixing plate pin 21 to approach the tongue-and-groove template 22;

[0027] It should be noted that the mortise and tenon template 22 here may also be a tenon template 23, and a placement groove (not shown in the figure) is provided on the base 1 corresponding to the placement of the mortise and tenon template 22 or the tenon template 23, and a plate pin groove 25 is provided on the mortise and tenon template 22 and the tenon template 23 corresponding to the fixing plate pin 21;

[0028] By adopting the above technical solution, the fixing plate pin 21 is moved toward the tongue and groove template 22 under the action of the pushing component, so that the laid film can be fixed on the tongue and groove template 22.

[0029] Reference Figure 1-3 , a bracket 2 is provided on the base 1, and a blanking component for providing a fixing plate pin 21 for the mortise and tenon template 22 is also provided on the bracket 2;

[0030] The blanking assembly includes a fixed plate pin box 3, a pressure block 4, an electric push rod 5, and a connecting plate 6. The fixed plate pin box 3 and the electric push rod 5 are fixed on the bracket 2. The pressure block 4 is slidably connected to the fixed plate pin box 3. The two ends of the connecting plate 6 are respectively connected to the pressure block 4 and the electric push rod 5. A limit assembly is also provided at the bottom of the fixed plate pin box 3;

[0031] By adopting the above technical scheme, the fixed plate pins 21 are evenly placed in the fixed plate pin box 3, and the telescopic end of the electric push rod 5 is connected to the connecting plate 6. The extension and retraction of the electric push rod 5 drives the pressure block 4 to press down the uppermost fixed plate pin 21 in the fixed plate pin box 3. The inner walls of the fixed plate pin box 3 are provided with protrusions (not shown in the figure) on both sides corresponding to the lowermost fixed plate pin 21. Therefore, when the lowermost fixed plate pin 21 in the fixed plate pin box 3 is pressed onto the base 1, the second to last fixed plate pin 21 will not fall onto the base 1 together under the action of the protrusions. At the same time, the limiting component prevents the fixed plate pin 21 in the fixed plate pin box 3 from falling without external force.

[0032] Reference Figure 1 The push assembly includes an electric push rod 15, an L-shaped bracket 16, and a push plate 24. The electric push rod 15 is arranged on the base 1, the output end of the electric push rod 15 is connected to the L-shaped bracket 16, and the other end of the L-shaped bracket 16 is connected to the push plate 24;

[0033] It should be noted that the bottom of the push plate 24 is in clearance with the top of the base 1, and the output end of the electric push rod 2 15 is a telescopic end;

[0034] It should be further explained that the L-shaped bracket 16 can make the pushing of the push plate 24 more stable;

[0035] By adopting the above technical solution, the electric push rod 15 is extended and retracted, driving the L-shaped bracket 16 to move, so that the push plate 24 pushes the fixed plate pin 21 to move toward the mortise and tenon template 22 or the tenon template 23 until the fixed plate pin 21 is fixed to the mortise and tenon template 22 or the tenon template 23.

[0036] Reference Figure 3 The limit assembly includes a support block 7, a limit plate 8, a limit spring 9, and a connecting block 10. The support block 7 is fixed to the bottom of the fixed plate pin box 3. The limit plate 8 rotates in the support block 7. The connecting block 10 is fixed to the limit plate 8. The two ends of the limit spring 9 are fixedly connected to the fixed plate pin box 3 and the connecting block 10 respectively.

[0037] By adopting the above technical solution, the limit spring 9 plays a resetting role, so that the limit plate 8 fits with the bottom of the fixed plate pin box 3 without external force. If the pressure block 4 is pressed down, the limit spring 9 is stretched and the limiting effect of the limit plate 8 is released. When the fixed plate pin 21 falls, the limit spring 9 is reset, and the limit plate 8 is also reset together.

[0038] Reference Figure 1 The base 1 is also provided with a film pushing component and a moving component for driving the film pushing component to move;

[0039] By adopting the above technical solution, the moving component drives the film pushing component to make the film on the mortise and tenon template 22 or the tenon template 23 fit better.

[0042] By adopting the above technical solution, driven by the moving component, the film pushing roller 13 rolls on the mortise and tenon template 22 or the tenon template 23, so that the film fits better. Under the action of the return spring, the rocker arm allows the film pushing roller 13 to slide in the arc slide rail 12, which can ensure that the film fits better and will not be damaged.
