Description

Technical Field

[0001] This utility model relates to the field of recycled concrete precast mold technology, and in particular to a recycled concrete precast component. Background Technology

[0002] Precast recycled concrete slabs require frame-like molds during prefabrication. Current molds generally include wooden and steel formwork structures. In wooden formwork structures, the wooden templates are connected by nails. During demolding, the nails are removed and the templates are broken open. Since the recycled aggregate used in recycled concrete is formed from waste concrete blocks through crushing, washing, and grading, the strength and durability of recycled concrete are generally weaker than ordinary concrete. Therefore, the demolding process is too violent and can easily damage the recycled concrete. In steel formwork structures, the steel templates are fixed together by bolts. The bolts can be removed during demolding, making the demolding process relatively stable. However, assembling and removing the bolts is time-consuming and labor-intensive, affecting production efficiency. Therefore, it is necessary to provide a recycled concrete precast component that is easy to assemble, quick to demold, and stable. Utility Model Content

[0003] In view of this, this utility model proposes a precast component made of recycled concrete, which aims to solve the problems of cumbersome mold assembly and disassembly and violent demolding process of existing precast recycled concrete slabs.

The first clip body and the second clip body are respectively formed with a first clamping part and a second clamping part. The torsion spring is disposed on the rotating shaft and drives the first clamping part and the second clamping part to move closer to each other.

[0008] The four strip templates are connected in sequence to form a frame structure, and the main plate of one strip template is attached to the end plate of another strip template. The fixing clip is set between two adjacent strip templates to clamp and fix the two strip templates.

[0010] A clamping plate is provided on the edge of the end plate away from the motherboard. The clamping plate is parallel to the motherboard, and the edge of the clamping plate away from the end plate forms a second clamping ridge.

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] refer to Figure 1 An embodiment of this utility model shows a precast component made of recycled concrete, including four strip templates 1 and multiple fixing clips 2;

[0033] like Figure 2 and Figure 3 As shown, the strip template 1 includes a main board 11, with an upper horizontal plate 12 and a lower horizontal plate 13 respectively provided on the upper and lower edges of the main board 11. End plates 14 are provided at both ends of the main board 11, and the end plates 14 are perpendicular to the main board 11. The end plates 14 are provided with clamping holes 141. The upper horizontal plate 12 and the lower horizontal plate 13 are arranged in parallel, and the upper horizontal plate 12 is perpendicular to the main board 11.

[0034] like Figure 4 As shown, the fixing clamp 2 includes a first clamping body 21, a second clamping body 22, a rotating shaft 23, and a torsion spring 24. The first clamping body 21 and the second clamping body 22 are hinged together by the rotating shaft 23. A first clamping part 211 and a second clamping part 221 are respectively formed on the first clamping body 21 and the second clamping body 22. The torsion spring 24 is disposed on the rotating shaft 23, and the torsion spring 24 drives the first clamping part 211 and the second clamping part 221 to move closer to each other.

[0035] Four strip templates 1 are connected in sequence to form a frame structure. The main plate 11 of one strip template 1 abuts against the end plate 14 of another strip template 1. The fixing clip 2 is set between two adjacent strip templates 1 to clamp and fix the two strip templates 1. Only one end plate 14 of one strip template 1 abuts against the main plate 11 of another strip template 1; more specifically, the end plate 14 at one end of the strip template 1 is used to abut against the main plate 11 of the other strip template 1, and the end plate 14 at the other end of the strip template 1 is used to connect to the fixing clip 2. Figure 5 As shown, the first clamping part 211 or the second clamping part 221 of the fixing clamp 2 is inserted into the clamping hole 141 of the end plate 14, thereby clamping and fixing the end plate 14 of one strip template 1 to the main plate 11 of another strip template 1.

[0036] In this way, the recycled concrete precast component can fix two adjacent strip templates 1 by fixing clamp 2, which is convenient and quick to assemble or demold and disassemble, effectively improving production efficiency. Moreover, the demolding process will not cause damage to the recycled concrete precast slab, thus improving production quality.

[0037] In some embodiments, such as Figure 3 and Figure 6 As shown, a first clamping rib 142 is formed on the side wall of the clamping hole 141 near the motherboard 11; a clamping plate 15 is provided on the edge of the end plate 14 away from the motherboard 11, the clamping plate 15 is parallel to the motherboard 11, and a second clamping rib 151 is formed on the edge of the clamping plate 15 away from the end plate 14; the inner sides of the first clamping part 211 and the second clamping part 221 are provided with clamping teeth 25, and the first clamping part 211 and the second clamping part 221 are respectively clamped on the first clamping rib 142 and the second clamping rib 151.

[0038] Specifically, in this embodiment, the first clamping rib 142 and the second clamping rib 151 are used to hold and limit the clamps on the first clamping part 211 and the second clamping part 221, which can prevent the fixing clip 2 from slipping, prevent the fixing clip 2 from falling off accidentally, and increase the stability of the connection structure.

[0039] Specifically, in the above scheme, the long strip template is a steel structure, and the main board 11, upper horizontal plate 12, lower horizontal plate 13, end plate 14 and clamping plate 15 are integrally formed or welded together.

[0040] Furthermore, the clamping plate 15 is a square plate, one edge of which is welded to the end plate 14, and the upper and lower edges of the clamping plate 15 are welded to the upper horizontal plate 12 and the lower horizontal plate 13, respectively. In this way, the clamping plate 15 can improve the structural strength of the end plate 14, prevent the end plate 14 from deforming, and ensure that the end plate 14 remains perpendicular to the main plate 11.

[0041] In some embodiments, such as Figure 1 As shown, the elongated template also includes multiple ribs 16, which are spaced apart along the length of the main plate 11. The ribs 16 are welded to the main plate 11, the upper horizontal plate 12, and the lower horizontal plate 13, respectively. In this embodiment, the ribs 16 improve the structural stability between the upper horizontal plate 12, the lower horizontal plate 13, and the main plate 11, ensuring that the lower horizontal plate 13 remains perpendicular to the main plate 11, and ensuring that the main plate 11 remains vertical when the lower horizontal plate 13 is placed horizontally.

[0042] In some embodiments, such as Figure 7As shown, it also includes a weight block 3, which is placed behind the strip formwork 1 to support it. The weight block 3 can be a cement block, steel column block, etc., and its position behind the strip formwork 1 further ensures that the strip formwork 1 does not shift during the pouring of recycled concrete.

[0043] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
