DETAILED DESCRIPTION

[0050] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] The terms "first", "second", "third" in this application are only used for descriptive purposes and cannot be understood as indicating the quantity of the indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of these features. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative positional relationship, motion conditions, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "include" and "have" and any of their variations are intended to cover non-exclusive inclusions. The process, method, system, product or equipment such as including a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.

[0054] The present application provides a demoulding device for assembled building components, which is used to demould a cylindrical shell mold 10 outside a cylindrical building component. Figure 1 As shown, the mold 10 is a cylindrical shell structure with an opening 12 at one end. When demoulding, the building component in the mold 10 is ejected along the direction of the opening 12. The outer side wall of the mold 10 is provided with a fixing hole 11.

[0055] like Figure 2-Figure 10 As shown, the demoulding device includes a disk assembly 100 and a rod assembly 200; the disk assembly 100 includes a supporting disk 110 and an impact disk 120 arranged in parallel, the supporting disk 110 and the impact disk 120 are connected by an axially retractable elastic member 130, and the supporting disk 110 is provided with at least one radial groove 113; the rod assembly 200 includes at least one folding rod 210, the folding rod 210 includes a first portion 211 extending radially along the supporting disk 110 and a second portion 212 parallel to the axial direction of the supporting disk 110, the first portion 211 is radially slidably connected in the radial groove 113, and the end of the second portion 212 away from the first portion 211 is located on the side of the impact disk 120 away from the supporting disk 110.

[0056] Among them, the demoulding device is in the demoulding state, the demoulding device is located outside the mold 10, at least a part of the inner side of the rod assembly 200 is fixed to the fixing hole 11, and the impact disk 120 is configured to be able to axially impact the support disk 110 after the elastic member 130 is freely released in the stretched state, so as to give the mold 10 instantaneous kinetic energy through the rod assembly to achieve demoulding. It is worth noting that the elastic member 130 can be axially retractable, which means that the elastic member 130 can be extended or shortened. In this embodiment, the elastic member 130 usually adopts a telescopic spring component. When the elastic member 130 is stretched, the impact disk 120 is away from the support disk 110. When the external force pulling the elastic member 130 disappears, the elastic member 130 recovers the deformation, and the impact disk 120 hits the support disk 110, and the support disk 110 transmits the action from the impact disk 120 to the rod assembly, and the rod assembly generates kinetic energy on the outer wall of the mold 10, thereby playing the effect of vibrating the mold 10, so that the mold 10 can be demoulded.

[0057] The demoulding device is in a waste scraping state, the demoulding device is located inside the mold 10, at least a portion of the outer surface of the rod assembly 200 is in contact with the inner surface of the mold, and the waste on the inner wall of the mold 10 is scraped off by rotating the rod assembly 200 around the axis of the demoulding device.

[0058] It can be seen that the demoulding device of the present application can realize two functions: demoulding the mold and scraping off the waste material on the inner surface of the mold 10 after demoulding.

[0059] When demolding, each folding rod 210 of the device can be pulled radially outward along the support plate 110 so that the second portion 212 of each folding rod 210 is located outside the mold 10, and then the engaging column 210 on the second portion 212 of the folding rod 210 is aligned with the fixing hole 11 on the mold 10 (such as Figure 3 As shown), each folding rod 210 is pushed radially inward along the support plate 110, so that the engaging column 2100 on the second part 212 of each folding rod 210 is inserted into the fixing hole 11 on the outer surface of the mold 10, and the assembly of the demoulding device and the mold 10 is completed. Then, demoulding can be performed. The specific operation of demoulding is to first manually pull the impact plate 120 away from the support plate 110 to stretch the elastic member 130, and then release the impact plate 120. Under the action of the elastic member 130 restoring the deformation, the impact plate 120 can hit the support plate 110 in a very short time, giving the support plate 110 an upward instantaneous kinetic energy, which is transmitted to the mold 10 through each folding rod 210, and the building components in the mold 10 will remain stationary due to inertia, so that the mold 10 and the building components are separated, that is, demoulding is achieved. If the impact plate 120 fails to achieve demoulding after one impact, the operation can be repeated for multiple times until demoulding is achieved.

[0060] After demoulding is completed, some concrete waste will remain on the inner surface of the mold 10. The demoulding device of the present application can be used to scrape off the waste of the mold 10. The specific operation is to first push each folding rod 210 of the device inward so that the distance between the end of the second part 212 of each folding rod 210 and the axis of the support plate 110 is smaller than the inner diameter of the mold 10, and then cover the mold 10 outside the demoulding device in an inverted manner (such as Figure 4 As shown in the figure, each folding rod 210 is pulled radially outward along the support plate 110, so that the outer side surface of the second part 212 of each folding rod 210 fits the inner side wall of the mold 10, and the top wall of the first part 211 of each folding rod 210 fits the inner top wall of the mold 10. By rotating the demoulding device, each folding rod 210 can be rotated in accordance with the inner surface of the mold 10, thereby scraping off the waste material on the inner surface of the mold 10. In order to enhance the scraping effect of the outer side of the folding rod 210 on the waste material, a scraping tooth structure can be provided on the outer side of the folding rod 210.

[0061] It should be noted that the “inside” and “outside” mentioned in the present application refer to relative to the mold 10, no matter the demolding device is covered on the outside of the mold 10 or the demolding device is placed on the inside of the mold 10, any two structural members, the one closer to the mold 10 is inside and the one farther away from the mold 10 is outside, or any two parts or two surfaces of a structural member, the one closer to the mold 10 is inside and the one farther away from the mold 10 is outside.

[0062] The demoulding device of the present application includes three or four folding rods 210, and each folding rod 210 is evenly distributed along the circumferential direction of the support plate 110. This embodiment is described by taking four folding rods 210 as an example, but the folding rods 210 can also be other numbers.

[0063] Please also read Figure 2 , Figure 5 and Figure 6 The support plate 110 includes a first plate surface 111 and a second plate surface 112. The first plate surface 111 is disposed opposite to the impact plate 120, and the second plate surface 112 is disposed opposite to the impact plate 120. A countersunk hole 114 is provided on the second plate surface 112. One end of the elastic member 130 is connected to the countersunk hole 114, and the other end is connected to the impact plate 120. When the elastic member 130 is in an unextended state, the elastic member 130 is completely located in the countersunk hole 114. By arranging the elastic member 130 in the countersunk hole 114, it can be ensured that the opposite surfaces of the impact plate 120 and the support plate 110 can collide and contact.

[0064] In order to ensure that the top surface of the first part 211 can contact the inner top wall of the mold 10 and facilitate the stable installation of the folding rod 210, the radial groove 113 of the present application penetrates the first disk surface 111 along the axial direction of the support disk 110 and does not penetrate the second disk surface 112. The lower part of the first part 211 in the vertical direction is located inside the radial groove 113, and the upper part is located outside the radial groove 113 so that the first part 211 can protrude from the first disk surface 111. The cross section of the radial groove 113 is an inverted T-shape, and the cross section of the first part 211 of the folding rod 210 is an inverted T-shape that matches the radial groove 113. Of course, in addition to the inverted T-shape, the cross section of the radial groove 113 and the cross section of the first part 211 can also adopt a dovetail shape, a trapezoidal shape with a narrow top and a wide bottom, etc., in order to allow the radial groove 113 and the first part 211 to limit each other.

[0065] A locking member for locking the relative position of the first part 211 and the radial groove 113 is provided between the first part 211 and the radial groove 113, so as to realize the sliding of the first part 211 of the folding rod 210 and the fixation between the first part 211 and the radial groove 113. The locking member includes a locking screw hole and a thread provided on the first part 211 of the folding rod, and cooperates with a locking bolt (not shown in the figure) in the locking screw hole, and the end of the locking bolt is pressed against or separated from the hole wall of the radial groove 113 to realize the locking and unlocking between the first part 211 of the folding rod and the radial groove 113. Of course, the locking member can also adopt other structures, such as a wedge block wedged between the first part 211 and the radial groove 113.

[0066] Continue to refer Figure 2 In the radial direction, the edge of the support plate 110 is located inside the edge of the impact plate 120, and the impact plate 120 is provided with a guide groove 121 extending in the radial direction thereof, and the second portion 212 of the folding rod 210 corresponds to the guide groove 121 of the impact plate 120. Figure 2 and Figure 8The second part 212 of the folding rod 210 includes a first section 2121 and a second section 2122 along its length direction. Along the radial direction of the support plate 110, the first section 2121 is located on the outer side of the support plate 110, and the first section 2121 slides in the corresponding guide groove 121, and the second section 2122 is located on the side of the impact plate 120 away from the support plate 110; along the radial direction of the impact plate 120, the inner side surface of the first section 2121 is located on the inner side of the inner side surface of the second section 2122, and the outer side surface of the first section 2121 is coplanar with the outer side surface of the second section 2122 and parallel to the axis of the impact plate 120. The second part 212 adopts the above-mentioned structure of being wide at the top and narrow at the bottom. On the one hand, it can guide the movement of the impact plate 120 through the cooperation between the first section 2121 and the guide hole 121. On the other hand, it can make the distance between the inner side surfaces of the second section 2122 larger than the outer diameter of the mold 10, thereby ensuring that the second section 2122 can cover the outside of the mold 10. On the other hand, the second section 2122 becomes narrower, and its vibration amplitude increases after being subjected to force, which is more conducive to demolding.

[0067] See also Fig. 9 When the demoulding device of the present application is used for scraping waste, in order to facilitate the rotation of the demoulding device, the demoulding device also includes a scraping drive shaft 300 detachably connected to the support plate 110 and the impact plate 120, and the scraping drive shaft 300 includes a square shaft 310, and a square sink 115 is provided at the center of the second disk surface 112 of the support plate 110, and a square hole 122 is provided at the center of the impact plate 120. The square shaft 310 passes through the square hole 122 and is inserted into the square sink 115, and the square shaft 310 is matched with the square hole 122 and the sidewall uniform surface of the square sink 115. Therefore, when the square shaft 310 rotates, it can drive the support plate 110, the impact plate 120 and each folding rod 210 to rotate, thereby achieving scraping of waste on the inner surface of the mold 10.

[0068] See again Figure 8 The folding rod 210 also includes a third part 213 parallel to the first part 211, the third part 213 is located at an end of the second part 212 away from the first part 211, and one end of the third part 213 is rotatably connected to the end of the second part 212, and the rotation axis of the third part 213 is parallel to the axis of the support plate 110.

[0069] When the demoulding device of the present application is used to scrape waste from the inner wall of the mold 10, the third parts 213 of all folding rods 210 can also be connected to increase the overall rigidity of the demoulding device and ensure the scraping effect of the waste from the outer side of the folding rod 210. Specifically, the scraping drive shaft 300 also includes a connecting disk 320, on which a connecting column 321 is provided, and a through hole 2131 is provided on the third part 213 of the folding rod. One connecting column 321 corresponds to one third part 213 of the folding rod. When the third part 213 of the folding rod is located inside the second part 212 of the folding rod, each connecting column 321 on the connecting disk 320 can penetrate into the corresponding through hole 2131.

[0070] The present application also provides a demoulding method for assembled building components, which uses the demoulding device to perform demoulding. Specifically, the method may include but is not limited to the following steps:

[0071] The demoulding device is covered on the outside of the mold 10 to be demoulded, and the mold 10 is demoulded by the demoulding device.

[0072] The demoulding device is placed inside the demoulded mold 10 , and the waste material on the inner surface of the mold 10 is scraped off by the demoulding device.

[0073] The demoulding method for assembled building components provided in the present application can realize two functions of demoulding the mold and scraping off the waste material on the inner surface of the mold 10 after the demoulding is completed through the demoulding device.

[0074] The steps in the embodiments of the present application do not necessarily have to be processed in the described order of steps.
