Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated building production, and in particular relates to a plugging device for slotting a PC component template. Background Art

[0002] PC is the abbreviation of precast concrete, which refers to concrete products produced in factories through standardized and mechanized methods. It has the advantages of good local structural performance, fast construction speed, energy saving in factory production, environmental protection and good fire resistance. It is often used in construction, transportation, water conservancy and other fields. Among them, in order to improve the good structural performance of PC components, it is necessary to set criss-cross steel bars inside the mold before pouring concrete in the mold to ensure that the PC components have good structural strength after solidification.

[0003] The video with the link https: / / v.douyin.com / ir2GcHFb discloses a PC component production device, in which the shape of the concrete is fixed by the groove formed by the PC component template. After natural cooling and forming, the whole piece is lifted up when demolding, and then the concrete and template at the corners are removed with a hammer to complete the production of the PC component.

[0004] However, in the technical solution disclosed in the above video, it is necessary to use a hammer to remove the concrete at the corners when demolding the PC component. The concrete here is formed by the concrete flowing out of the grooves where the steel bars are placed on the template. Since steel bars must be placed inside the PC component to enhance the structural strength, and in order to facilitate the fixation of the steel bars before pouring and the removal of the mold from the PC component during demolding, the groove on the mold must be set to a U shape and cannot be set to a circular shape with better sealing. This not only causes the concrete to flow out of the mold, resulting in difficulty in controlling the quality standards of the molded concrete and waste of resources, but also the workers need to remove the concrete at the corners when demolding, which results in time-consuming and labor-intensive work and pollution of the workshop environment. Summary of the invention

[0005] The purpose of the present invention is to provide a sealing device for PC component template slots to solve the problems in the prior art that the slots for placing steel bars on the mold for producing PC components cannot be sealed, resulting in waste of resources, difficulty in controlling the quality of PC components, time-consuming and labor-intensive demoulding, and pollution of the workshop environment.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0024] See also Figure 1-Figure 7 As shown, a PC component template slotting plugging device comprises a workbench 1 placed on the ground; a template body 2 is arranged on the workbench 1, and the cross section of the template body 2 is L-shaped; slots for placing steel bars are evenly arranged on the template body 2, and steel bars are placed in the slots; uniformly arranged reinforcing ribs 3 are fixed at the corners of the template body 2, and the reinforcing ribs 3 are used to improve the compressive strength of the template body 2 itself; The template body 2 is provided with a blocking plate 4 on one side of the right-angle surface, and the height of the blocking plate 4 is equal to the sum of the height of the template body 2 and the depth of the slot 6; a lifting block 8 is fixedly connected to the middle of the top of the blocking plate 4 to facilitate operators to install the blocking plate 4.

[0025] Please refer again Figure 6 , Figure 7 As shown, a fitting groove 5 is provided on the blocking plate 4 at a position corresponding to the steel bar groove; a fitting slot 6 is provided on the template body 2 and the workbench 1 at a position corresponding to the blocking plate 4; and a cutout 7 is provided on the template body 2 at a position corresponding to the reinforcing rib 3 to prevent the blocking plate 4 from being obstructed by the reinforcing rib 3.

[0026] When placing straight steel bars in the notches on the template body 2, the fitting grooves 5 on the blocking plate 4 are matched with the notches on the template body 2, and then the template body 2 is inserted downward. Since the opening of the fitting grooves 5 is downward and the opening of the notches is upward, the blocking plate 4 and the mold body can cooperate with each other to block the upper and lower parts of the steel bars, thereby preventing concrete from flowing out of the notches.

[0027] Please refer again Figure 3 , Figure 7 As shown, the blocking plate 4 is provided with a slide groove 502 at a position corresponding to the bottom of the fitting groove 5 ; a shaft rod 501 is slidably arranged in the slide groove 502 , and the shaft rod 501 is rotatably connected to the bottom of the reinforcing rib 3 .

[0028] An adjustment groove 503 is formed on the reinforcing rib 3 at a position corresponding to the shaft rod 501 , and the shaft rod 501 is slidably disposed inside the adjustment groove 503 .

[0029] Please refer again Figure 2 As shown, adjustment blocks 504 are fixedly connected at both ends of the shaft rod 501; a plurality of insertion holes 505 are provided on the side of the template body 2 corresponding to the positions of the adjustment blocks 504; an insertion rod 506 is inserted into the insertion hole 505, and the insertion rod 506 consists of a rod body and a round cap, and is used to cooperate with the insertion hole 505 and the adjustment block 504 to fix the position of the shaft rod 501 inside the adjustment groove 503.

[0030] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below: When placing a straight steel bar inside the notch on the mold body, a plurality of template bodies 2 are placed at a designated position on the workbench 1, and a closed groove for accommodating concrete is formed by the template bodies 2. Then, the steel bar is placed inside the notch on the template body 2. At this time, the shaft rod 501 is moved to a designated position in the adjustment groove 503 according to the length of the steel bar, and is fixed by the cooperation of the insertion rod 506, the insertion hole 505 and the adjustment block 504. like Figure 3 As shown, if the length of the steel bar is short (this embodiment is shown in the shortest state), the rotating shaft is moved to the bottom of the adjustment groove 503. At this time, the end of the blocking plate 4 away from the shaft rod 501 is directly rotated, and the blocking plate 4 rotates around the shaft rod 501, so that the matching groove 5 passes through the end of the steel bar when rotating, until the blocking plate 4 is in contact with the vertical surface of the template body 2, and then the blocking plate 4 is pressed down. Two situations occur: the lower part of the first blocking plate 4 is inserted into the slot 6; the lower part of the second matching groove 5 is in contact with the upper part of the steel bar, and the upper part of the notch on the mold body is in contact with the lower part of the steel bar. Figure 4 The state shown in the figure shows that the preparation work before concrete is completed, and finally the concrete is poured into the groove enclosed by the mold body; From the above, it can be seen that after pouring concrete inside the enclosed mold body, the upper and lower parts of the steel bars are blocked with the cooperation of the blocking plate 4 and the mold body, which can prevent the concrete from leaking from the notch position on the mold body, thereby wasting resources and polluting the workshop environment, and it is more convenient and quicker to demould; In addition, the lower part of the first blocking plate 4 is inserted into the slot 6 provided on the workbench 1, and the formwork body 2 is fixed on the workbench 1 and cannot be moved, so that the purpose of quickly fixing the formwork body 2 is achieved. When disassembling it, the solidified concrete can be quickly taken out from the inside by only reverse operation, which is convenient, simple and efficient. like Figure 5 As shown, and compared Figure 3 If the length of the steel bar is long (this embodiment is shown in its longest state), before fixing the position of the shaft 501, move the shaft 501 to the highest point of the adjustment slot 503, and then fix it by using the insertion rod 506, the insertion hole 505 and the adjustment block 504, and then rotate the end of the blocking plate 4 away from the shaft 501, and repeat the above operation until the shaft 501 is formed. Figure 4 The state shown in the figure can be poured with concrete; As can be seen from the above, the position of the engaging groove 5 on the sealing plate 4 can be changed by fixing the shaft rod 501 at different positions inside the adjusting groove 503. When the shaft rod 501 is located at the bottom of the adjusting groove 503, the engaging groove 5 can only allow shorter steel bars to pass through when the sealing plate 4 rotates. When the shaft rod 501 is located at the top of the adjusting groove 503, longer steel bars can pass through. Therefore, by changing the position of the shaft rod 501, the operator can detect whether the steel bar is within the specified distance (referring to the distance that the end of the steel bar protrudes from the PC component after the concrete solidifies) when rotating the sealing plate 4. There is no need for subsequent secondary processing to cut it, which will not waste resources, is convenient and saves trouble, and saves labor. Example 2

[0031] Please refer again Figure 8-Figure 10 As shown, a movable groove 511 is provided on the blocking plate 4 at a position corresponding to the notch of the template body 2, and the middle of the top of the movable groove 511 is a semicircular notch that fits the steel bar; symmetrically arranged movable plates 512 are slidably arranged in the movable groove 511, and inclined surfaces 513 are provided at the corners close to each other at the bottom of the movable plates 512, and the inclined surfaces 513 are used for the steel bar to pass through the middle; the movable plate 512 is also provided with a semicircular notch that fits the steel bar at the position corresponding to the steel bar; The movable plate 512 is fixedly connected to a guide rod 515 at a position corresponding to the middle of the movable groove 511; the movable groove 511 is provided with a guide hole 516 at a position corresponding to the guide rod 515, and the guide rod 515 slides inside the guide hole 516, so as to tilt the movable plate 512 when sliding inside the movable groove 511; the movable plate 512 is fixedly connected to positions on both sides of the guide rod 515 with symmetrically arranged springs 514, and the springs 514 are used to help the movable plate 512 to reset after moving inside the movable groove 511, so that the corresponding movable plates 512 are closed to each other.

[0032] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below: When placing the U-shaped steel bar inside the notch on the mold body, the sealing plate 4 can be directly attached to the vertical surface of the mold body, the inclined surface 513 between the movable plates 512 is aligned with the steel bar, and then pressed down, and the movable plate 512 is forced to move inside the movable groove 511 by the steel bar. At this time, the movable plates 512 are away from each other, and the sealing plate 4 continues to move downward until the steel bar enters the corresponding semicircular recess. In this way, the upper part of the U-shaped steel bar is blocked by the sealing plate 4, the middle part of the U-shaped steel bar is blocked by the movable movable plate 512 on the sealing plate 4, and the lower part of the U-shaped steel bar is completed by the template body 2, so that the U-shaped steel bar is placed inside the notch on the mold body. The purpose of all-round blocking is achieved, and the concrete will not flow out from the notch where the steel bar is placed when pouring concrete, thereby avoiding waste of resources and pollution of the workshop environment. At the same time, the movable plate 512 with the inclined surface 513 is used to cooperate with the fixed steel bar to block the notch. The blocking method is quick and convenient, which is conducive to improving the production speed of PC components.

[0033] It is worth noting here that the slot 6 jointly opened on the workbench and the mold body is set at the bottom of the movable plate 512. Therefore, through the cooperation between the movable plate 512 and the slot 6, the blocking plate 4 can fix the position of the mold body, thereby realizing the rapid enclosure of the mold body into the shape required for pouring concrete, thereby improving the production speed of PC components and reducing the working time of operators.
