[0002] In the construction field, drainage construction is a crucial task, which is related to the safety, comfort and service life of buildings. Among them, key elements such as casting concrete for the drainage ditch cover plate and the die for reserving drainage holes constitute the core part of drainage construction. During the one-time concrete pouring process of the drainage ditch cover plate, on the premise of being fast, convenient, efficient and cost-reducing, after the die for the drainage holes is made and used, how to quickly remove the die without damaging the cover plate concrete has become the key point. In the past, in drainage projects, the reserved drainage holes were made of wood or iron, and these two methods have the following problems:
[0003] 1. The material of the reserved drainage hole die is wood. After being cut into the shape and size required by the design, a layer of demoulding agent needs to be applied to the outside. After the concrete cover plate is formed, the wooden die has been deformed by the surrounding concrete and needs to be removed with a crowbar, which is likely to damage the formed cover plate concrete around, and the wooden material has a high cost and cannot be reused.
[0004] 2. The material of the reserved drainage hole die is iron. After being machined into the shape and size required by the design on a machine tool, a layer of demoulding agent needs to be applied to the outside. After the concrete cover plate is formed, although it is easy to remove, the manufacturing cost is high and it is time-consuming and laborious.
[0005] Therefore, a die for casting concrete with reserved drainage holes for a drainage ditch cover plate that can ensure convenience, speed and low cost needs to be studied. Content of the Utility Model
[0006] To solve the above technical problems, the utility model provides a die for casting concrete with reserved drainage holes for a drainage ditch cover plate.
[0007] The technical solution of the utility model is realized as follows:

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without making creative efforts belong to the scope of protection of the utility model.
[0022] Such as Figure 1 and Figure 2As shown in the figure, a precast concrete drainage hole mold for a drainage ditch cover provided in the first embodiment includes a plate body part 1 and a tape 2. The plate body part 1 is prefabricated according to the size of the reserved drainage hole, and the tape 2 is wrapped around the outside of the plate body part 1. By arranging the tape 2 to directly contact the poured concrete, the demolding operation is more convenient. Compared with the prior art, there is no need to apply a demolding agent, and the plate body part 1 can be reused, having the advantages of convenient production, low cost, and easy use.
[0023] The plate body part 1 is a foam board, specifically a polystyrene foam board, and the tape 2 is a BOPP tape 2.
[0024] The specific operation steps are as follows:
[0025] Cut the polystyrene foam board into the width and thickness of the reserved drainage hole required by the design, wrap the tape 2 tightly around the outside of the plate body part 1, and when setting up the formwork for the drainage ditch cover, place the drainage hole mold at the reserved position.
[0026] By setting it like this, the plate body part 1 made of polystyrene foam board has good compressive performance, is convenient for processing and transportation, has low production cost, and after the concrete cover is formed, the mold can be removed conveniently and quickly.
[0027] As Figures 3 to 5 shown in the figure, in the second embodiment, the tape 2 includes an inner layer body 2.1 and an outer layer body 2.2. The inner layer body is wrapped around the outside of the plate body part 1, and the adhesive surface of the inner layer body 2.1 faces outward. The outer layer body 2.2 is wrapped around the outside of the inner layer body 2.1, and the adhesive surface of the outer layer body 2.2 faces inward.
[0028] By setting it as above, the inner layer body 2.1 can be used to prevent the outer layer body 2.2 from directly adhering to the outside of the plate body part 1. During the demolding process, the plate body part 1 can be more easily pulled out of the tape 2, making the demolding more convenient.
[0029] The plate body part 1 includes an intermediate part 1.1 located in the middle and a first part 1.2 and a second part 1.3 respectively sleeved at both ends of the intermediate part 1.1. Opposite ends of the first part 1.2 and the second part 1.3 are provided with docking surfaces 1.4.
[0030] When wrapping the tape 2 around the outside of the plate body part 1, first sleeve the first part 1.2 and the second part 1.3 at both ends of the intermediate part 1.1, so that the docking surfaces 1.4 on the first part 1.2 and the second part 1.3 are mutually attached. Furthermore, the tape 2 can make the whole plate body part 1 have stronger stability and improve the forming effect.
[0031] The docking surface 1.4 is an inclined surface. There are two inner belt bodies 2.1, and the two inner belt bodies 2.1 are respectively wrapped on the first part 1.2 and the second part 1.3, and the ends of the inner belt bodies 2.1 extend to the docking surface 1.4.
[0032] During specific operation, first wrap the two inner belt bodies 2.1 on the first part 1.2 and the second part 1.3 respectively, and then after putting the first part 1.2 and the second part 1.3 on the middle part 1.1, the parts of the two inner belt bodies 2.1 corresponding to the docking surface 1.4 will be bonded to each other to realize the pre-fixation of the combined plate body part 1.
[0033] The outer ends of both the first part 1.2 and the second part 1.3 extend outward relative to the tape 2 to have exposed parts 3, and the outer end face of the middle part 1.1 is provided with a socket part 4 that can be sleeved on the outer ends of the exposed parts 3.
[0034] During specific operation, first wrap the two inner belt bodies 2.1 on the first part 1.2 and the second part 1.3 respectively, then dock the first part 1.2 and the second part 1.3, and use the parts of the inner belt bodies 2.1 corresponding to the docking surface 1.4 to bond to each other to realize the connection of the first part 1.2 and the second part 1.3. Then insert the middle part 1.1 between the first part 1.2 and the second part 1.3, and make the socket part 4 sleeved on the exposed part 3. In this way, use the socket part 4 to stably connect and fix the first part 1.2 and the second part 1.3.
[0035] When removing the mold, the middle part 1.1 can be first pulled out to make the first part 1.2 and the second part 1.3 in a hollow state. At this time, it is more convenient to pull out the first part 1.2 and the second part 1.3, and further, it can prevent the plate body part 1 from being damaged when pulled out, so that it can be reused.
[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
