Abstract
Description
Technical Field
[0001] The utility model relates to a concrete casting formwork, in particular to a casting formwork assembly for a detection hole of a concrete structure. Background Art
[0002] The detection of concrete structures refers to the evaluation and detection of the performance, damage and defects of concrete structures through a series of detection means to determine the integrity, safety and durability of the structures. Its main purpose is to ensure the safety and reliability of the structures, timely detect and evaluate the structural damage and defects, and provide a scientific basis for the maintenance, reinforcement and transformation of the structures.
[0003] In the detection of concrete structures, there are various methods that can be adopted:
[0004] 1. Non-destructive testing methods: such as the rebound method, ultrasonic method, radar method, etc. These methods are used for detection without affecting the performance of the concrete structure. For example, the ultrasonic method uses the difference in the propagation speed of ultrasonic waves in different materials to detect the internal defects of concrete; radar detection uses radar signals to penetrate the concrete structure to detect the internal defects and steel bars of the concrete.
[0005] 2. Semi-destructive testing methods: such as the drilling method, post-installed pull-out method, etc. These methods are used for local damage detection of the structure without affecting the load-bearing capacity of the concrete structure. For example, the drilling method drills samples in the concrete structure for laboratory analysis and testing to evaluate the quality and durability of the structure; the post-installed pull-out method drills holes, grinds grooves, embeds anchor bolts and installs a pull-out instrument on the surface of the hardened concrete for a pull-out test to measure the ultimate pull-out force, thereby detecting the concrete strength.
[0006] 3. Visual inspection: This is one of the most commonly used detection methods, which can directly observe problems such as cracks and peeling on the surface of the concrete.
[0007] Among them, the drilling method is a commonly used quality detection method, which analyzes the quantity and size of holes by drilling samples in the concrete. Although this method is accurate, it will cause certain damage to the concrete components.
[0008] With the increase in the service time of building structures, the concrete structure reinforcement projects tend to increase. The detection holes left during the concrete structure detection process need to be restored in a timely manner. The existing restoration method is to support with ordinary formwork. In actual operation, it is not convenient for pouring and grouting, and it may cause the grouting in the hole to be not dense, resulting in engineering quality problems.
[0009] Therefore, it is necessary to propose a casting formwork that is convenient for construction and can ensure the repair quality. Content of the Utility Model

[0037] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0038] Embodiment
[0039] A casting formwork assembly for a detection hole 6 of a concrete structure, as Figures 1-3As shown, it is installed on a concrete member and used for the restoration pouring of the inspection hole 6 on the concrete member.
[0040] The pouring formwork assembly includes a grouting mold main body 1, a grouting pipe 3, and a grouting mold fixing member 5.
[0041] A pair of the grouting mold main bodies 1 are provided, which are respectively located at both ends of the inspection hole 6. The grouting mold main bodies 1 on both sides are respectively abutted against the two side surfaces of the concrete member through the grouting mold fixing members 5, and the grouting mold main bodies 1 on both sides and the concrete member form a closed area.
[0042] A grouting hole 2 is opened on one side of the grouting mold main body 1, and the grouting pipe 3 is connected to the grouting hole 2; an overflow hole 4 is opened on the other side of the grouting mold main body 1.
[0043] More specifically, in this embodiment:
[0044] As Figure 1 shown, this pouring formwork assembly is used for the repair pouring of the inspection hole 6 on the concrete member.
[0045] This pouring formwork assembly includes a grouting mold main body 1, a pouring mold fixing member, and a grouting pipe 3.
[0046] As Figure 1 shown, a pair of grouting mold main bodies 1 are provided, which are respectively arranged at both ends of the inspection hole 6 and respectively abutted against the two side surfaces of the concrete member; the pouring mold main bodies on both sides and the concrete member together form a closed area. A sealing member 7 is further provided between the surface of the pouring mold main body and the concrete member, as Figure 2 , which is used to control the sealing performance of the closed area to avoid the leakage of concrete slurry and the mixing of air bubbles during pouring. The sealing member 7 can adopt a sealing strip, such as a circumferential rubber strip, which is completely pressed between the grouting mold main body 1 and the concrete member.
[0047] The pouring mold fixing member adopts a fixing screw, which penetrates through the inspection hole 6 and the pouring mold main bodies on both sides, and after being adjusted in place, nuts are tightened at both ends to connect the pouring mold main bodies on both sides and achieve effective fixation on the concrete member. Further, a gasket can be provided between the nut and the pouring mold main body.
[0048] A grouting hole 2 is provided on one side of the grouting mold main body 1, and an overflow hole 4 is provided on the other side of the grouting mold main body 1; the grouting pipe 3 is connected to the grouting hole 2 to pour the concrete slurry for repair into the closed area. Both the grouting hole 2 and the overflow hole 4 are higher than the highest point in the inspection hole 6, so that the inside of the inspection hole 6 can be filled with the concrete slurry by its own weight and ensure density.
[0049] As Figure 2 、 3As shown in the figure, the grouting mold body 1 is composed of a central convex part and a circumferential pressing part communicating with each other. The convex part is a partial sphere, and the pressing part is annular. The grouting hole 2 and the overflow hole 4 are both arranged on the convex part and are inclined relative to the horizontal plane; the seal 7 is pressed between the pressing part and the concrete member. A certain cavity is formed inside the convex part to accommodate and buffer the injected concrete slurry, and at the same time, it can also ensure that when overflow occurs at the overflow hole 4, the inspection hole 6 is filled with concrete slurry. A screw hole 8 is also opened at the center of the convex part for the pouring mold fixing part to pass through. The grouting mold body 1 is made of metal or rigid foam plastic, with good structural strength to ensure the reliability of the pouring process.
[0050] When the pouring template assembly is in use:
[0051] During assembly, the grouting mold body 1 is placed at both ends of the inspection hole 6 respectively, and the grouting mold body 1 is locked and pressed on the concrete surface through the grouting mold fixing part 5 to form a closed area; a grouting pipe 3 is connected to the grouting hole 2.
[0052] During grouting, the grouting pipe 3 injects concrete slurry through the grouting hole 2, and when the other overflow pipe overflows, it means that the grouting is completed.
[0053] During disassembly, after the grouting is completed and the concrete slurry has finally set, the grouting pipe 3, the grouting mold fixing part 5 and the grouting mold body 1 are removed in sequence, the seal 7 is cleaned, the concrete protruding above the concrete member surface is chiseled to make it flat, and the small holes of the grouting mold fixing part 5 are filled.
[0054] In summary, this pouring template assembly is a concrete pouring template, suitable for the grouting restoration of the inspection hole 6 of the concrete structure; since both the grouting hole 2 and the overflow hole 4 are higher than the vertex of the inspection hole 6, the self-weight of the injected concrete slurry can be used to ensure the denseness of the grouting in the inspection hole 6, and the construction is convenient and fast.
[0055] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the utility model. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative labor. Therefore, the present utility model is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the present utility model according to the disclosure of the present utility model should be within the protection scope of the present utility model.
