DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-14 , the present invention provides a technical solution:

[0041] Example:

[0042] like Figure 1-10 As shown, an assembled prefabricated mold for concrete encapsulation includes a base plate 1, a heightening plate 2 and a connecting member 3, wherein a first horizontal connecting portion 4 is provided at one side end of the base plate 1, and a second horizontal connecting portion 5 matching the first horizontal connecting portion 4 is provided at the other side end of the base plate 1 (two adjacent base plates 1 are connected by the first connecting portion and the second connecting portion during installation), and a first vertical connecting portion 6 is provided at the top of the base plate 1 along its length direction, and the first vertical connecting portion 6 is provided with at least two vertical first connecting holes 7, and the first connecting hole 7 matches the connecting member 3 (matching here means that the shape of the first connecting hole 7 matches the connecting member 3, that is, the connecting member 3 can be matched and connected with the first connecting hole 7);

[0043] The two side ends of the heightened plate 2 are respectively provided with a first horizontal connection part 4 and a second horizontal connection part 5, the bottom of the heightened plate 2 is provided with a second vertical connection part 8 matched with the first vertical connection part 6, the top of the heightened plate 2 is provided with a third vertical connection part 9 matched with the second vertical connection part 8, the third vertical connection part 9 is provided with a second connection hole 10 corresponding to the first connection hole 7 above and below, and the second connection hole 10 extends to pass through the bottom of the heightened plate 2;

[0044] The base plate 1 and the heightened plate 2 are connected via a first connection hole 7 , a second connection hole 10 and a connection member 3 .

[0045] The connecting member 3 is a plate-like structure with a dumbbell-shaped cross section. The connecting member 3 is arranged in this way to avoid displacement in the horizontal direction and improve the stability during connection.

[0046] The bottom of the connector 3 is provided with an insertion portion 11. The insertion portion 11 is a pointed structure, which is provided to facilitate the insertion of the connector 3 into the soil.

[0047] The first horizontal connecting portion 4 is a T-shaped slot, and the second horizontal connecting portion 5 is a T-shaped block matching the first horizontal connecting portion 4 .

[0048] The first vertical connection portion 6 is a plate-shaped structure, the second vertical connection portion is a groove structure matched with the first vertical connection portion 6 , and the third vertical connection portion 9 is a plate-shaped structure matched with the second vertical connection portion 8 .

[0049] Working principle: Before pouring cement, assemble the base plate 1 according to the required pouring length. Multiple base plates 1 are connected head to tail through the first horizontal connection part 4 and the second horizontal connection part 5. Then, the heightened plate 2 is spliced ​​with the base plate 1 according to the required pouring height (two adjacent heightened plates 2 are connected through the first horizontal connection part 4 and the second horizontal connection part 5). If a single heightened plate 2 cannot meet the height requirement, it can be achieved by stacking and splicing multiple heightened plates 2. When the heightened plate 2 is spliced ​​with the base plate 1, the second vertical connection part 8 at the bottom of the heightened plate 2 is first matched with the first vertical connection part 6 at the top of the base plate 1. At this time, the first vertical connection part 6 and the second vertical connection part 8 play a role in positioning and fixing the heightened plate 2. Then, the second connection hole 10 on the heightened plate 2 is made to correspond to the first connection hole 7 on the base plate 1 one by one, and the connection part 3 is inserted after the correspondence, and the connection part 3 is inserted into the soil to make the overall structure stable. After the base plate 1 and the heightened plate 2 are set on both sides of the pouring place, cement can be poured.

[0050] The present invention adopts prefabricated components for assembly, and has the advantages of convenient construction operation, stable structure, reusability, high turnover rate, safety, environmental protection, controllable quality, and convenient transportation.

[0051] Furthermore, the base plate and the heightening plate are made of aluminum alloy material. This arrangement is lightweight and convenient to construct, and is suitable for single-soldier operation.

[0052] The base plate and the heightened plate are respectively provided with ribs for reinforcement on the outside; Figure 1 Taking the heightened plate as an example (similar to the heightened plate), the middle is a "W"-shaped plate rib, and the two sides are "V"-shaped plate ribs, which are welded into a whole with the flat ends of the first and second horizontal connecting parts, the flat end of the first vertical connecting part, the flat end of the bottom of the plate and the two panels, and are discontinuous and not through when encountering the first connecting hole.

[0053] Among them, 1. Considering that the upper part of the precast mold is subjected to great lateral pressure from the concrete, it is easy to tilt outward, causing deviation in the specifications of the upper part of the concrete envelope; 2. The deformation of the horizontal connection part is easy to cause concrete leakage, which is a potential risk point for quality defects and directly affects the use effect of the precast mold. Therefore, additional measures are needed to limit it.

[0054] To address the above problems, a steel wire rope with a diameter of 4 mm is used for transverse pulling reinforcement on the outside of the first horizontal connection part. A fixed slot is set on the outer panel of the precast mold (base plate, heightened plate) on one side, and a tensioner component is set on the outer panel of the precast mold (base plate, heightened plate) on the other side. A 4 mm steel wire rope is used as a pull rope. A safety ring is provided at the head end of the steel wire rope, which can be put on the slot on the other side and then tightened through the tensioner hand lever, which can effectively control the creep of the precast mold.

[0055] A fastening buckle should be set at the bottom of the outer side of the heightened plate, which is connected to the upper fastening point of the outer side of the base plate by rotation to prevent the upper and lower plates from separating when the concrete vibrates. Two buckles should be evenly arranged on one plate. This setting is a well-known technology for those skilled in the art and will not be described here or shown in the figure.

[0056] Embodiment 2:

[0057] like Fig.11 and Fig.12 As shown, the difference between this embodiment and embodiment 1 is that a slide rail 12 is provided on the side of the base plate 1, a slide block 13 is slidably connected to the slide rail 12, and a support rod 14 is hinged at one end of the slide block 13 away from the slide rail 12.

[0058] Working principle: After the base plate 1 is installed, the base plate 1 is supported by the support rod 14 and the sliding block 13 to prevent it from falling due to the horizontal thrust during cement pouring, thereby improving the stability of the base plate 1. Specifically, after the support rod 14 forms an angle of 30°-45° with the vertical direction, the sliding block 13 is moved downward, and the sliding block 13 drives the support rod 14 downward when it moves downward, and stops when the bottom of the support rod 14 enters the soil. At this time, the support rod 14 and the sliding block 13 can provide certain support for the base plate 1, and then the sliding block 13 is knocked to make it continue to move downward, and the sliding block 13 moves downward to squeeze the support rod 14 so that it penetrates into the soil layer, thereby improving the support force for the base plate 1.

[0059] Furthermore, if Fig.11 As shown, a self-locking slider 15 is also provided on the slide rail 12, and the self-locking slider 15 is arranged above the sliding block 13. The side of the self-locking slider 15 away from the slide rail 12 is hinged with one end of a connecting semicircular ring 16, and the other end of the connecting semicircular ring 16 is hinged with a connecting rod 17, and the connecting rod 17 is fixedly connected to the sliding block 13. The end of the connecting semicircular ring 16 and the self-locking slider 15 that is hinged is fixedly connected with a lever 18.

[0060] The self-locking slider 15 moves downward synchronously with the sliding block 13 when the sliding block 13 moves downward. When the sliding block 13 is fixed, the self-locking slider 15 is locked on the slide rail 12. When the mold needs to be removed, the lever 18 is pressed downward, and the force is transmitted to the connecting rod 17 under the action of the lever 18, and then to the sliding block 13. The sliding block 13 is pulled upward and can be easily pulled up. When the sliding block 13 is pulled to slide upward, the support rod 14 is separated from the soil, and the mold can be removed very conveniently at this time.

[0061] The self-locking slide block 15, the lever 18 and the connecting rod 17 can realize the retraction of the support rod 14 with very little force, so as to facilitate the demoulding.

[0062] Furthermore, if Fig.13 and 14 As shown, the slide rail 12 is a T-shaped slide rail, and the self-locking slider 15 includes an adjustment handle 19, a basic slider 20 and two locking blocks 21. A T-slot 22 is provided in the middle of the basic slider 20, and placement holes 23 connected to the T-slot 22 are provided at both ends of the basic slider 20. The T-slot 22 is slidably connected to the slide rail 12. The two locking blocks 21 are respectively arranged in the two placement holes 23. The locking blocks 21 are slidably connected to the basic slider 20. The locking blocks 21 are each provided with a first threaded hole 24 that passes through the locking blocks 21 along its axial direction. The first threaded hole 24 is eccentrically arranged. A screw 25 is connected to the adjustment handle 19, and the screw 25 is connected to the two locking blocks 21 through the first threaded hole 24. When the adjustment handle 19 is rotated, the screw 25 drives the locking blocks 21 to complete the locking and fixing of the self-locking slider 15 as a whole. The self-locking slider 15 is thus arranged with a simple structure and a good self-locking effect.
