Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering, specifically to an adjustable one-time molding concrete stepping stone casting mold. Background Technology

[0002] Stepping stones were originally stones placed in shallow water as walkways to facilitate crossing rivers. With the development of technology, their applications have expanded to include water conservancy projects, landscape design, ecological restoration, agriculture, and transportation. In water conservancy projects, especially at the top of dams, stepping stones are often installed in specific locations to facilitate access for maintenance and construction workers. In this field, concrete stepping stone structures are typically designed in a "runway-like" pattern.

[0003] In current water conservancy engineering construction, stepping stones are generally constructed by concrete pouring. The construction method is to reserve the required space according to the dimensions of the stepping stone structure design, assemble and support them to form a hollow groove using certain auxiliary tools or molds, and then pour concrete and wait for it to solidify.

[0004] However, in actual engineering projects, the design dimensions of concrete stepping stones vary from construction site to construction site. Construction workers need to fabricate, assemble, and support molds on-site according to the different dimensions of the concrete stepping stone structures. These processes are not only tedious and complex but also significantly impact the work efficiency of construction workers. Furthermore, traditionally fabricated on-site molds are usually disposable. Therefore, there is an urgent need for a concrete stepping stone mold that can be adaptively adjusted to different design dimensions and formed in one piece. This mold would simplify the on-site stepping stone construction process and allow for repeated use.

[0005] Based on the above, this utility model proposes an adjustable one-time molding concrete stepping stone casting mold, which can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable, one-time molding concrete stepping stone casting mold to solve the problems of cumbersome and complex construction and repeated use of concrete stepping stones of different sizes. The technical solution adopted by this utility model is as follows:

[0007] This utility model provides an adjustable, one-time molding concrete stepping stone casting mold, including a telescopic device, a fixed side plate, a splicable side plate, an adjustable arch device, and a splicable telescopic screw. The telescopic device includes a fixed part and a telescopic part, with the fixed part connected and fixed to the fixed side plate. The splicable side plate is spliced ​​on-site to the telescopic part of the telescopic device. The adjustable arch device includes an arched rubber pad, a support screw, a slide rail, and a slot. The slide rail and slot are fixed to the fixed part of the telescopic device, and the support screw is connected to the slide rail for horizontal movement. The arched rubber pad is telescopic in the slot. The splicable telescopic screw is used to splice between two molds, and the spacing is adjustable. Furthermore, all structural devices can be used repeatedly.

[0008] The fixed side plate is connected to the fixed part of the telescopic device. One side of the fixed side plate is used to block concrete, and the other side is provided with a buckle to connect with the fixing screw on the fixed part of the telescopic device. Its length is determined according to the common size of concrete stepping stones in actual engineering, the height is 0.2m, the thickness is usually 10-20mm, and the material can be made of wood, plastic, aluminum, steel, iron, etc. The fixed side plates are symmetrically arranged on both sides of the concrete stepping stone.

[0009] Furthermore, the telescopic device includes a telescopic part and a fixed part. The fixed part is connected and fixed to the fixed side plate. The telescopic part adjusts the length of the mold by means of a telescopic screw. The maximum adjustment range of the length should be determined according to the common size of concrete stepping stones in actual engineering projects. The height is 0.2m, the diameter of the telescopic rod is 10-20mm, and the thickness of the non-screw part can be determined according to the engineering requirements and the diameter of the telescopic rod, generally 20-40mm. The telescopic device is symmetrically arranged on both sides of the concrete stepping stone.

[0010] Furthermore, the splicable side panels can be spliced ​​on the telescopic part of the telescopic device. One side is used to block concrete and keep it on the same plane as the fixed side panel. The other side is provided with a latch to splice with the telescopic screw of the telescopic part of the telescopic device. The length of the splicable side panels should be made according to actual needs. One or more splicable side panels can be set for splicing. Their height and thickness are the same as the fixed side panels. The materials can be wood, plastic, aluminum, steel, iron, etc. The splicable side panels are symmetrically arranged on both sides of the concrete stepping stones.

[0011] Furthermore, the adjustable arch device includes an arched rubber pad, a support screw, a slide rail, and a slot. One side of the arched rubber pad is used to block concrete, and the other side is supported by the support screw. The support screw can be moved horizontally and fixed by the slide rail and pin device on both sides. Slots are set at both ends of the arch, that is, slots are set at the connection between the fixed side plate and the telescopic device, and are fixed. The arch size is controlled by the movement of the support screw and the slots. Therefore, the arch size of the rubber pad (arch width, arch arc length) can be freely adjusted to adapt to concrete stepping stones of different sizes. The thickness of the arched rubber pad can be in the range of 10-15mm, and the height is 0.2m.

[0012] Furthermore, the connectable telescopic screw is used for splicing between two molds. It is spliced ​​at the non-rod parts at both ends of the telescopic device between the two molds. The distance between the two molds is adjusted by the telescopic screw. After adjusting to a suitable distance, it is fixed by means of pins, etc. The telescopic range is determined according to the common distance between concrete stepping stones in actual engineering.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] 1. This utility model adjusts the length of the concrete stepping stone mold by fixing and splicing the telescopic device, fixed side plate and splicable side plate to each other, and by telescopically extending the telescopic screw of the telescopic device. The fixed side plate and splicable side plate are fixed to the telescopic device by setting a bayonet to connect and fix them to the screw, so as to adapt to concrete stepping stones of different lengths and ensure the stability of the mold structure.

[0015] 2. After fixing and splicing the expansion joint, fixed side plate and splicable side plate into a whole, place one on each side of the concrete stepping stone. The placement distance can be adjusted to adapt to concrete stepping stones of different widths.

[0016] 3. The support screw and arch rubber pad in the adjustable arch device are controlled by the slide rail and pin device to move and fix the support screw horizontally. At the same time, the slots are set at both ends of the arch, that is, the slots and pins are set at the connection between the fixed side plate and the telescopic device, so that the arch rubber pad can freely extend and retract along the slots and be fixed, in order to adapt to concrete stepping stones with different arch sizes (arch width, arch arc length).

[0017] 4. By utilizing the telescopic flexibility of the splicable telescopic screws and the fixing with pins, the distance between the molds can be adjusted to adapt to concrete stepping stones with different spacings, and to ensure the stability of the mold structure.

[0018] 5. All structural components of the mold can be reused repeatedly;

[0019] In summary, this utility model utilizes a telescopic device, fixed side plates, splicable side plates, an adjustable arch device, and splicable telescopic screws for fixing and splicing. It employs telescopic screws, slots, and slide rails to achieve structural sliding and expansion, and uses locking devices and pins for fixation. This allows for the assembly of an adjustable, one-time-use concrete stepping stone casting mold to accommodate the casting and forming of "playground circular track" type concrete stepping stones of varying lengths, widths, arch sizes, and spacings. This simplifies the construction process, allows for repeated use, reduces the tedious and complex on-site fabrication, assembly, and support work for construction personnel, and improves their work efficiency.
