Description

Technical Field

[0001] The utility model relates to the technical field of concrete slab demoulding, in particular to an auxiliary demoulding device. Background Art

[0002] Precast concrete panels are a common concrete component widely used in various types of buildings. After the precast concrete panels are formed, they need to be removed from the forming mold, i.e. demoulding. Traditional demoulding is usually done by manually prying or knocking the mold template to separate it from the concrete panel. The required prying or knocking force is relatively large, workers are easily fatigued, and the production efficiency is relatively low.

[0003] At present, the utility model with the publication number CN217967583U proposes an auxiliary demoulding device, including a frame, on which a conveying roller and a conveying motor are arranged, a pressure head assembly is arranged above each of the conveying rollers, and a top mold assembly is arranged below, the top mold assembly includes two groups of lifting rod groups and a lifting motor for driving each of the lifting rod groups to rise or fall synchronously, the lifting rod group includes a plurality of lifting screws, each of the lifting screws is respectively located between two adjacent conveying rollers at corresponding positions, and each of the lifting screws is respectively sleeved with a lifting screw nut connected to the lifting motor. The concrete slab is pressed against the conveying roller by setting the pressure head assembly, and then the side mold located on the outer peripheral surface of the concrete slab is lifted by the top mold assembly to realize demoulding, which is suitable for demoulding the side membrane plate of the forming mold. Since the separation resistance between the concrete slab and the side mold is mainly overcome by the lifting force of the top mold assembly, the workers are not easily fatigued and the production efficiency is relatively high.

[0004] However, the above-mentioned prior art still has some shortcomings when in use: 1. It has great limitations when in use, because concrete slabs have various specifications, and the above-mentioned prior art shows that the position of the lifting screw rod used for ejection when separating the concrete slab and the side plate on its outer peripheral surface is fixed, which means that it is only applicable to the demolding of concrete slabs of one specification; 2. The structure is relatively bulky and occupies a large space. It needs to use a crane for demolding, which results in high cost.

[0005] Therefore, the utility model provides an auxiliary demoulding device. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1 and Figure 2 The utility model provides a technical solution: an auxiliary demoulding device, including a base 1, one end of the base 1 is fixedly connected to a plug plate 2, one end of the plug plate 2 is inserted into the bottom of the concrete slab when in use, and the top of the base 1 is fixedly connected to a hanging plate 3 located above the plug plate 2. Specifically, the top of the base 1 is fixedly connected to a column 11 fixedly connected to one end of the hanging plate 3, and the outer peripheral wall of the thread sleeve 6 is fixedly connected to a guide sleeve 62 sleeved on the outside of the column 11 through a support plate 61. The bottom of the hanging plate 3 is fixedly connected to a pressure pile 4 close to the free end, and the bottom of the pressure pile 4 is opposite to the top of the concrete slab when in use, and a pressure head 8 is arranged at the bottom of the pressure pile 4, and the bottom of the pressure head 8 is against the top of the concrete slab when in use.

[0022] The top of the base 1 is rotatably connected with a lead screw 5, and the lead screw 5 is rotatably connected with the hanging plate 3. Specifically, the top of the base 1 is fixedly connected with a positioning sleeve 12 rotatably connected with the bottom of the lead screw 5, and the hanging plate 3 is fixedly connected with a limit sleeve 13 rotatably connected with the lead screw 5. The lead screw 5 is screwed with a thread sleeve 6 slidably connected with the base 1 up and down. When the lead screw 5 rotates forward and reversely, the thread sleeve 6 is driven to move up and down. The outer peripheral wall of the thread sleeve 6 is fixedly connected with a top plate 7 located at the bottom. The function of the top plate 7 is to push up. When the top plate 7 is in use, it is located at the bottom of the side of the forming template. When the thread sleeve 6 moves upward, it will separate the side mold wall of the forming template and the concrete slab.

[0023] In this embodiment, the outer wall of the positioning sleeve 12 is fixedly connected with the limit plates 121 located on both sides of the plug plate 2. When in use, the limit plates 121 and the outer side walls of the forming template are abutted against each other. The top of the screw 5 is fixedly connected with a handle 51, which is an operating component for manually controlling the rotation of the screw 5. The function of the limit plates 121 is to prevent the base 1 from twisting when the screw 5 is screwed.

[0024] In this embodiment, the outer peripheral wall of the wire sleeve 6 is fixedly connected to the L-shaped plate 63, the bottom of the L-shaped plate 63 is fixedly connected to one end of the top plate 7, and the upper end surface of the plug plate 2 is provided with a placement groove 21 matching the top plate 7. The placement groove 21 has the function of hiding the top plate 7, the purpose is to facilitate the top plate 7 to follow the plug plate 2 to be inserted under the concrete slab, wherein the top plate 7 is located at the bottom of the side plate of the forming mold.

[0025] In this embodiment, the pressure head 8 and the pressure pile 4 are detachably connected. Specifically, the top of the pressure head 8 is fixedly connected with a threaded rod 82, and the bottom of the pressure pile 4 is provided with a threaded hole that is screwed and connected with the threaded rod 82. The function of this arrangement is to facilitate the adjustment of the height of the pressure head 8 according to the thickness of the concrete slab, so that the pressure head 8 and the top of the concrete slab are more compatible. The bottom of the pressure head 8 is fixedly connected with a pressure plate 81, which is against the top of the concrete slab when in use.

[0026] Working principle: 1. Docking, first use a crowbar to lift the concrete slab containing the forming mold (for example, a rectangular frame mold), then insert the insert plate 2 under the concrete slab, while ensuring that the top plate 7 is located directly below the side plate of the forming mold, and that the limit plate 121 and the outer side wall of the side plate of the forming mold are against each other. In this way, several devices are installed on the periphery of the concrete slab.

[0027] Second, demoulding, first manually screw the pressure head 8 so that the pressure plate 81 presses against the upper end surface of the concrete slab, and then manually rotate the lead screw 5 through the handle 51. At this time, the thread sleeve 6 moves upward, and the top plate 7 pushes up the side plates of the forming mold. During this process, a hammer can be used to hit the side plates, thereby easily driving the forming mold to a loose state relative to the concrete slab. The device in other positions can be operated in this way to finally realize the demoulding process of the entire forming mold.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
