Description

Technical Field

[0001] This application relates to the field of concrete pouring technology, and in particular to a plastic mold for concrete pouring. Background Technology

[0002] In the construction industry, concrete pouring in on-site construction environments requires the use of molds. The molds are arranged and positioned in a predetermined location, forming a semi-enclosed cylindrical space with an open top. Release oil is then applied to the inner wall of the mold before pouring concrete. After solidification, the concrete is demolded. Alternatively, the concrete pouring process can occur in a workshop, where precast concrete components are fabricated and transported to the site for assembly. Regardless of the method, concrete molds are indispensable.

[0003] Under current technology, stainless steel molds are the most common, but they have high manufacturing costs, are heavy and difficult to transport, and have low plasticity, making them unsuitable for scenarios with a large number of concrete blocks and complex shapes. If different stainless steel molds are produced for different concrete blocks, the cost-effectiveness will be low.

[0004] Therefore, lightweight and easily transportable plastic molds have low manufacturing costs, high plasticity, and are easy to produce. Even when producing different plastic molds for different concrete blocks, the cost remains low. More importantly, plastic molds are recyclable, and their utilization rate is gradually increasing. However, plastic molds also have some drawbacks, such as low structural strength at joints, making them difficult to expand, and the relatively thin material properties making it difficult to incorporate other structures into the mold body, thus limiting their flexibility. Utility Model Content

[0005] To improve the flexibility of concrete pouring molds, this application provides a plastic mold for concrete pouring.

[0006] The present application provides a plastic mold for concrete pouring, which adopts the following technical solution:

[0007] A plastic mold for concrete pouring, comprising:

[0008] A unit board with multiple perforations on its surface, the perforations being evenly distributed along multiple edges of the unit board;

[0009] The sealing plate has multiple insert rods formed on its surface to fit the through holes. Each insert rod corresponds to one of the through holes. The length of the insert rod is the same as the thickness of the unit plate. When the sealing plate is attached to the unit plate, the insert rods are inserted into and close the through holes.

[0010] A connection structure is provided on multiple edges of the unit plate for connecting the unit plates, and the connection structures on adjacent sides of the unit plate are different.

[0011] By adopting the above technical solution, the unit plate serves as the basic unit of the plastic mold for concrete pouring. The unit plates are connected to each other to expand the plate area and form a mold for concrete pouring. The unit plates are connected by a connecting structure. Due to the gravity in the vertical direction, the connection structure of the two opposite side walls in the vertical direction can be distinguished from the connection structure of the two opposite side walls in the horizontal direction.

[0012] The perforations on the unit plate are for inserting reinforcing bars or plastic holes, for molding concrete soil, or for directly inserting reinforcing bars during the molding process of the concrete base; when the concrete body does not require the insertion of reinforcing bars, a sealing plate is used to cover the unit plate and seal the perforations on the unit plate.

[0013] Optionally, the thickness of the closing plate is less than the thickness of the unit plate.

[0014] By adopting the above technical solution, the main function of the sealing plate is to seal the perforations on the unit plate. Therefore, the plate surface does not need to be too thick to fit the unit plate, which can save costs.

[0015] Optional, also includes:

[0016] The flat plate has a surface area larger than the distribution area of ​​the perforations on the unit plate but smaller than the surface area of ​​the unit plate. The unit plate has a groove inside parallel to its surface that is adapted to the flat plate. The flat plate is inserted into the unit plate and closes the multiple perforations.

[0017] By adopting the above technical solution, a flat plate can replace the above-mentioned sealing plate. When the concrete body does not require reinforcement, the flat plate can be directly inserted into the groove inside the unit plate to complete the sealing of the perforations on the unit plate.

[0018] Optionally, the thickness of the flat plate is less than one-quarter of the thickness of the unit plate.

[0019] By adopting the above technical solution, the plate is used to seal the perforation and prevent concrete slurry from flowing out of the perforation. The plate is only stressed in the part corresponding to the perforation, and the stress area is small. Therefore, the overall thickness of the plate can be relatively thin. The installation of the unit plate and the plate can be stabilized by relying on the plug-in structure between the plate and the unit plate.

[0020] Optionally, the connection structure includes:

[0021] Connecting teeth are provided on two opposite sides of the unit plate, and the connecting teeth on the two opposite sides of the unit plate are distributed alternately so that the edges of two adjacent unit plates mesh.

[0022] Connecting blocks are formed on an adjacent side of the connecting teeth and are evenly distributed along one side of the unit plate;

[0023] Connecting grooves are formed on opposite sides of the connecting blocks, corresponding one-to-one and fitting to the connecting blocks. The connecting grooves are inserted into the connecting blocks to connect adjacent unit boards.

[0024] By adopting the above technical solution, the connecting teeth are structures that extend and connect unit plates in the horizontal direction, and are used to extend unit plates in the horizontal direction; the connecting block and the connecting slot insertion structure can better utilize the effect of gravity to make the connecting block stably inserted into the connecting teeth. In fact, the connecting block can also be regarded as an extended connecting tooth.

[0025] Optionally, the connecting teeth on the same side of the unit plate are provided with insertion holes parallel to the corresponding edge of the unit plate.

[0026] By adopting the above technical solution, the insertion hole is equipped with connecting teeth. After the connecting teeth are aligned in the horizontal direction and the unit board is expanded horizontally, the construction personnel can directly place a plastic rod into the insertion hole to achieve a stable connection between the two unit boards.

[0027] Optionally, the length of the connecting tooth is the same as the thickness of the unit plate.

[0028] By adopting the above technical solution, at the vertical corner in the horizontal direction, the connecting teeth of the two unit plates are vertically engaged. Under vertical engagement, the length of the connecting teeth is the same as the thickness of the unit plate, so that the connecting teeth are vertically and seamlessly engaged, sealing the side edges between adjacent unit plates.

[0029] The construction workers aligned the insertion holes on the connecting teeth on both sides and fixed the unit boards at the corners of the two units.

[0030] Optional, also includes:

[0031] The bending plate has two opposite edges forming a preset angle, and the two opposite edges of the bending plate are adapted to the connecting teeth.

[0032] By adopting the above technical solution, the bent plate is used in situations where it is not perpendicular and has a certain angle. The construction personnel set the two sides of the bent plate to a preset angle according to the prefabricated components. One side is connected to the unit plate by plastic rod, and the other side is connected to another unit plate by plastic rod. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0037] This application discloses a plastic mold for concrete pouring. (Refer to...) Figure 1 A plastic mold for concrete pouring includes a unit plate 1, which is a rectangular plate. Multiple perforations 15 are opened on the surface of the unit plate 1, perpendicular to the surface of the unit plate 1. The multiple perforations 15 are evenly distributed along two adjacent sides of the unit plate 1. Simply put, the perforations 15 are rectangularly distributed on the surface of the unit plate 1. The perforations 15 on the unit plate 1 are used to insert reinforcing bars. When the unit plate 1 is used to form a concrete pouring mold, the reinforcing bars are inserted into the perforations 15 and are directly retained after the concrete solidifies.

[0038] Reference Figure 1 Connecting teeth 11 are formed on opposite sides of the unit plate 1 in the horizontal direction. The connecting teeth 11 on both sides are indirectly distributed so that two adjacent unit plates 1 can be connected and expanded in the horizontal direction. In order to strengthen the connection structure when the unit plate 1 is expanded in the horizontal direction, the tooth body of the connecting teeth 11 is vertically provided with insertion holes 12. Both insertion holes 12 are distributed in the center of the connecting teeth 11, so that when the connecting teeth 11 of the two unit plates 1 are connected, the plastic rod can be inserted into the insertion hole 12 to prevent the unit plate 1 from detaching.

[0039] Reference Figure 1 A connecting groove 13 is provided on the top edge of the vertical unit plate 1, and a connecting block 14 is provided on the bottom edge. The connecting groove 13 and the connecting block 14 are adapted to each other, so that the connecting groove 13 can be inserted into the connecting block 14 to complete the vertical expansion between the unit plates 1. Under the action of gravity and the pressure of the upper unit plate 1, the unit plates 1 are stably connected.

[0040] Reference Figure 1 The tooth length of the connecting tooth 11 is numerically the same as the thickness of the unit plate 1, that is, two adjacent unit plates 1 can also be vertically and seamlessly meshed, which is used for vertical corner forming of concrete.

[0041] Reference Figure 2 Since not all corners of the concrete soil are right angles, this embodiment also includes a bending plate 4 to accommodate situations where two unit plates 1 are not perpendicularly adjacent. The two edges of the bending plate 4 form a certain angle, and connecting teeth 11 are provided at opposite edges. Insertion holes 12 are vertically opened on each connecting tooth 11. Construction workers manufacture the bending plate 4 according to the actual bending angle requirements of the concrete body.

[0042] Reference Figure 1 Considering the absence of steel reinforcement in the concrete soil, the perforations 15 need to be sealed. Therefore, this embodiment describes two methods for sealing the perforations 15. Firstly, this embodiment uses a flat plate 3, with slots for inserting the plate 3 into the unit plate 1. The plate 3 is inserted into the slot and abuts against the bottom of the slot. The area of ​​the plate 3 must be larger than the distribution area of ​​the perforations 15, so that its surface can cover all the perforations 15 when inserted. Secondly, this embodiment also uses a sealing plate 2, with insert rods 21 formed on its surface. Each insert rod corresponds to and fits the perforation 15. The length of the insert rod 21 is the same as the thickness of the unit plate 1, so that when the sealing plate 2 is attached to the unit plate 1, the insert rods 21 seal the perforations 15.

[0043] Reference Figure 1 The thickness of both the sealing plate 2 and the flat plate 3 is less than the thickness of the unit plate 1. Furthermore, the thickness of both is less than one-quarter of the thickness of the unit plate 1, so as to save materials while satisfying the effect of sealing the perforation 15.

[0044] The implementation principle of a plastic mold for concrete pouring in this application embodiment is as follows: In the horizontal direction, the unit plate 1 is connected by connecting teeth 11 and fixed by inserting plastic rods into the insertion holes 12; if the angle needs to be changed, the connecting teeth 11 intersect vertically at the vertical angle and are connected by bending plates 4 at the bending angle; in the vertical direction, the unit plate 1 is connected by connecting blocks 14 and connecting grooves 13.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
