Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and in particular to a standardized marking hole mold. Background Technology

[0002] In recent years, with the booming infrastructure and real estate market, the number of buildings such as hotels, hospitals, schools, resettlement housing, and commercial housing has been increasing. Sealing the surveying holes is a crucial step in the later stages of construction, directly affecting the integrity, waterproofing, and safety of the building structure. During construction, at least two surveying holes need to be reserved on each floor for measurement and surveying.

[0003] like Figure 4 and Figure 5 As shown, this is a previous generation of standardized molds for marking holes in existing technology. Most of them use a truncated square box with a smaller bottom and a larger top, which is fixed to the marking hole reserved on the bottom template. However, this type of standardized mold for marking holes has the following shortcomings in actual use: First, the existing technology uses a truncated square box to be fixed to the reserved hole on the board surface. During the concrete pouring and vibration process, the truncated square box is easy to tilt, resulting in the deviation of the marking hole position; Second, the tilt of the reserved truncated square box causes one side of the hole to be in the shape of an "eight", and there is a risk of concrete falling off after the hole is sealed; Third, the side of the marking hole is straight up and down, and the water seepage path is short, which poses a great risk of leakage.

[0004] In view of this, it is particularly important to design and manufacture a layout hole mold that can prevent the pre-reserved layout hole from shifting during the concrete pouring process and reduce the risks of concrete falling off and leakage after secondary sealing. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of skewing, displacement, hole blockage and concrete falling off that easily occur in the actual concrete pouring process of the fixed-shape mold used in the existing technology for setting out holes, which reduces the finished product effect after the setting out hole is cast. Therefore, a fixed-shape setting out hole mold is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A standardized wire-layout hole mold includes a bottom template, wire-layout holes formed on the bottom template, a mold positioned above the wire-layout holes, and a concrete layer filling the space between the upper end of the bottom template and the outside of the mold. The lower end of the mold is integrally fixedly connected to a recessed step that fits against the bottom template and the wire-layout holes. The concrete layer has stepped holes formed to accommodate the mold and the recessed step. A fixing part is provided between the recessed step and the bottom template to prevent displacement and deflection of the mold during casting.

[0008] As a further description of the above technical solutions:

[0009] The fixing part comprises a fixing hole arranged at four corners of the lower recessed step and a fixing nail penetrating through the fixing hole and fixed at the bottom template.

[0010] As a further description of the above technical solutions:

[0011] The left and right sides of the inside of the mold are symmetrically fixed and connected with two handles in parallel distribution.

[0012] As a further description of the above technical solutions:

[0013] The inside of the mold is rotatably installed with a pry mold rotating handle in an L-shaped structure at the front side and the middle of the rear side.

[0014] As a further description of the above technical solutions:

[0015] The middle of the lower recessed step is arranged with a positioning hole corresponding to the pay-off hole.

[0016] As described above, due to the adoption of the above technical solutions, the beneficial effects of the present application are:

[0017] In the present application, the overall shape of the pay-off hole mold is a stepped structure with a small lower part and a large upper part, and the fixing hole and the fixing nail are arranged on the lower recessed step. The positioning hole below the mold can be oriented and aligned with the pay-off hole on the bottom template, and then the fixing nail can be nailed on the bottom template through the fixing hole on the lower recessed step. At this time, the entire mold can be stably fixed between the bottom template and the pay-off hole, and after the concrete is solidified and formed, a stepped hole can be formed on the concrete layer. The use of this structure pay-off hole mold can avoid the risk of falling off after the pay-off hole is blocked, and at the same time, the length of the leakage line is lengthened to avoid the risk of leakage. In addition, the mold and the bottom template are firmly fixed, which can effectively avoid the problems of displacement and skewing during the concrete pouring process.
