Description

Technical Field

[0001] This utility model relates to a steel-concrete protective layer device for the bottom of primary and secondary beams in a basement, and in particular to a mold for making long strip pads and a structure for the long strip pad protective layer. Background Technology

[0002] In concrete structure engineering, reinforcement spacers are typically used to ensure the correct position of reinforcing bars and the appropriate thickness of the concrete cover. Traditional spacers are mostly small, block-shaped components, including concrete spacers, plastic support spacers, and cement mortar spacers. While widely used in practical engineering, these spacers have revealed several issues affecting construction quality and efficiency. Regarding manufacturing costs, some traditional spacers are produced using custom molds and specialized materials, resulting in cumbersome production processes and high unit costs, making it difficult to meet the economical needs of rapid deployment on large-scale construction sites. In terms of construction efficiency, traditional spacers are often scattered, requiring manual placement under or binding with the reinforcing bars, leading to low operational efficiency and a tendency for displacement or detachment during concrete pouring, increasing construction time and quality control difficulty. Regarding structural stability, small-volume spacers have a small bearing area and poor vibration resistance, especially during concrete vibration, where they are prone to displacement or breakage, resulting in inconsistent concrete cover thickness and affecting structural durability and safety. Furthermore, localized bearing points can easily create weak zones within the structure, negatively impacting overall load-bearing capacity. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a mold for making long strip pads with low manufacturing cost, high construction efficiency and good stability, as well as a protective layer structure for long strip pads.

[0004] To solve the above-mentioned technical problems, the long strip pad block manufacturing mold of this utility model includes an integrally formed mold body. The upper surface of the mold body is provided with several horizontally equidistant grooves. Each groove penetrates the front and rear end faces of the mold body to form a cavity structure into which reinforcing bars can be inserted.

[0005] The cross-section of the groove is rectangular or trapezoidal.

[0006] The length of the groove is not less than 400mm.

[0007] The mold body has a cuboid structure.

[0008] The mold body is made of wood.

[0009] The protective layer structure of the long strip pad made by the mold includes the long strip pad body, and each long strip pad body has a steel bar running through it longitudinally.

[0010] The cross-sectional shape of the elongated pad block body is rectangular or trapezoidal.

[0011] The long strip pad body is made of C25 concrete.

[0012] Advantages of this utility model:

[0013] (1) The mold is easy to process and has low cost: The mold body is made of wood as one piece, which is easy to process and has low material cost, making it suitable for on-site rapid production and short cycle use.

[0014] (2) The pad blocks are easy to make and the production cost is low: The long strip pad block making mold of this utility model adopts an integrated molding structure. The whole is a cuboid with grooves distributed horizontally at equal intervals and connected from front to back, which facilitates the batch molding of multiple long strip pad blocks. The mold can be reused, reducing the production cost.

[0015] (3) Facilitates the pre-embedding of reinforcing bars: The groove runs through the front and rear ends to form a through cavity structure. Reinforcing bars are inserted first and then concrete is poured, which improves construction efficiency and ensures good bonding between concrete and reinforcing bars, which is beneficial to the overall strength of the pad block structure.

[0016] (4) The long strip pad protective layer has high structural stability: The long strip pad made by the mold has steel bars embedded in it, which forms a positioning and support effect. The uniform force helps to form a continuous and stable protective layer.

[0017] (5) Improve construction accuracy and efficiency: The mold of this utility model can be used to mass-produce multiple long strip pad protective layer structures, eliminating the need for manual separate production and positioning, significantly improving construction efficiency, and effectively ensuring the consistency of the thickness of the steel reinforcement protective layer in the structure.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the elongated pad manufacturing mold and the elongated pad protective layer structure of this utility model. Example

[0022] The long strip pad block manufacturing mold of this utility model includes a mold body 1 made of wood in one piece. The mold body 1 has a cuboid structure. Several horizontally equidistant grooves 2 are opened on the upper surface of the mold body 1. Each groove 2 penetrates the front and rear end faces of the mold body 1 to form a cavity structure into which steel bars can be inserted. The cross-section of the groove 2 is rectangular or trapezoidal. The length of the groove 2 is not less than 400mm, so that the steel bars on both sides protrude by 100mm when the steel bars are placed inside. A protective layer structure for long strip pad blocks made by the long strip pad block manufacturing mold includes a long strip pad block body 3. Each long strip pad block body 3 has a steel bar 4 running through it longitudinally. The cross-sectional shape of the long strip pad block body 3 is rectangular or trapezoidal. The long strip pad block body 3 is made of C25 concrete.

[0023] Manufacturing process: In actual use, first place the long strip pad block mold flat on a horizontal working platform; then, insert the reinforcing bars into the grooves 2 of the mold body 1 in sequence and adjust their positions so that the two ends of the reinforcing bars extend evenly out of the front and rear end faces of the mold, with an outward extension length of about 100mm; then, pour C25 concrete evenly into each groove 2; after the concrete has initially set and reached a certain strength, demolding is performed to obtain the long strip pad block protective layer structure wrapped with reinforcing bars.
