Description

Technical Field

[0001] This utility model relates to the field of concrete specimen curing technology, specifically to a curing frame for concrete specimen curing. Background Technology

[0002] Concrete specimens are standard samples used to test the mechanical properties of concrete. The accuracy of the test results is directly determined by the standardization of their preparation, curing, and testing. The core of concrete specimen curing is to simulate a standard temperature and humidity environment to ensure normal strength development; the curing frame is the key equipment for achieving standardized curing and ensuring specimen quality.

[0003] Existing concrete specimen curing racks are multi-layered structures formed by combining multiple columns and placement plates. Concrete specimens are neatly arranged on the upper side of the placement plates during curing. However, these racks lack surrounding barriers or other structures, failing to provide adequate protection for the concrete specimens. Adding protective plates directly to the outside would hinder the handling and placement of specimens during curing, and would also impede operator observation of the curing process. Utility Model Content

[0004] To address the aforementioned issues, a curing frame for concrete specimen curing is provided. The outer frame provides better protection for the concrete specimens during curing, preventing damage from impacts. A push-pull mechanism allows the concrete specimens inside the outer frame to be pushed out, facilitating curing work. The modular design of the movable frame, receiving frame, and baffle ensures stable placement of the concrete specimens while allowing for easy removal by staff. The mesh panel at the bottom of the receiving frame drains water and, in conjunction with the isolation mesh panel, allows for observation of the curing process from different angles.

[0005] To address the problems of existing technologies, this utility model provides a curing frame for curing concrete specimens, including an outer frame and a movable frame horizontally arranged inside the outer frame along its height direction, each of the movable frames being able to move horizontally along the width direction of the outer frame.

[0006] A push-pull assembly is provided on the rear side of the outer frame. The push-pull assembly includes a telescopic cylinder and a push frame. The cylinder body of the telescopic cylinder is hinged to the outer frame, and the push rod end of the telescopic cylinder is hinged to a drive arm fixed on the push frame.

[0007] Multiple push arms are rotatably arranged on the outer side of the push frame along its length extension direction. Multiple slots that cooperate with the push arms are horizontally opened on the rear side of the outer frame. The end of each push arm away from the push frame passes through the slot at the same height and continues to extend to be hinged to the moving frame at the same height.

[0008] A receiving frame is placed horizontally at the movable frame, and a baffle that cooperates with the receiving frame is also provided at the end of the movable frame.

[0009] Preferably, both ends of the baffle are provided with elastic elements, and the end of the movable frame is provided with a positioning groove that cooperates with the elastic elements.

[0010] Preferably, two guide rails are fixedly provided on the rear side of the outer frame. The two guide rails are located at both ends of the push frame, and the ends of the push frame extend vertically to the inside of the guide rails and can move along the extension direction of the guide rails.

[0011] Preferably, each of the movable frames has a sliding portion extending laterally on both sides, and a sliding groove that mates with the sliding portion is horizontally recessed on the inner wall of the inner side of the outer frame.

[0012] Preferably, the portion of the outer frame located on the inner wall at the bottom of the sliding groove extends laterally to the bottom of the movable frame to form a support portion, and both the support portion and the sliding portion are symmetrically arranged about the plane containing the axis of symmetry of the movable frame.

[0013] Preferably, the bottom of the receiving frame is set with a grid, and both sides of the outer frame are equipped with highly visible isolation mesh panels.

[0014] Preferably, the side view of the movable frame is L-shaped, and the working height of the baffle is higher than the working height of the receiving frame.

[0015] The advantages of this utility model compared to the prior art are:

[0016] 1. Setting up an outer frame can better protect the concrete specimens during curing, preventing them from being damaged by external objects. The concrete specimens inside the outer frame can be pushed out by the push-pull mechanism, making it convenient for staff to carry out curing work.

[0017] 2. The modular design of the mobile frame, receiving frame, and baffle allows for stable placement of concrete specimens while enabling easy removal by staff for replacement or further maintenance.

[0018] 3. The mesh panel at the bottom of the receiving frame can drain water and, in conjunction with the isolation mesh panel, facilitates the observation of the curing process of the concrete specimens from different angles by the staff. Attached Figure Description

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figure 1-4 As shown, a curing frame for curing concrete specimens includes an outer frame 1 and a movable frame 2 horizontally disposed inside the outer frame 1 along its height direction. Each movable frame 2 can move horizontally along the width direction of the outer frame 1.

[0029] It should be noted that during use, simply push or pull the movable frame 2 outwards towards the outer frame 1, place the concrete specimen on the movable frame 2, and then push it back to its original position. At this point, the outer frame 1 can protect the concrete specimen inside, preventing it from being damaged by contact with external objects.

[0030] See Figure 1 and Figure 2As shown, a push-pull assembly is provided on the rear side of the outer frame 1. The push-pull assembly includes a telescopic cylinder 1a and a push frame 1b. The cylinder body of the telescopic cylinder 1a is hinged to the outer frame 1, and the push rod end of the telescopic cylinder 1a is hinged to a drive arm fixed on the push frame 1b.

[0031] It should be noted that the telescopic cylinder 1a can be used to fully extend the movable frame 2 inside the outer frame 1 to facilitate the operator's maintenance operations.

[0032] See Figure 2-5 As shown, multiple push arms 1b1 are rotatably arranged on the outer side of the push frame 1b along its length extension direction. Multiple slots that cooperate with the push arms 1b1 are horizontally opened on the rear side of the outer frame 1. The end of each push arm 1b1 away from the push frame 1b passes through the slot at the same height as it and continues to extend to be hinged to the moving frame 2 at the same height.

[0033] It should be noted that during use, the telescopic cylinder 1a pulls the pusher frame 1b along the length of the rear side of the outer frame 1 via the drive arm at the push rod end. At this time, the pusher frame 1b will slowly push the moving frame 2 outward along the channel via the push arm 1b1 rotatably connected to it.

[0034] The vertically arranged telescopic cylinder 1a, push frame 1b, push arm 1b1, and channel configuration can reduce the space required for the push-pull assembly and make full use of the internal space of the outer frame 1. The installation space is small, and the operating space is taken up by the internal space of the outer frame 1, which effectively reduces the overall footprint of the maintenance frame.

[0035] See Figure 3-7 As shown, a receiving frame 2a is horizontally placed at the movable frame 2, and a baffle 2b that cooperates with the receiving frame 2a is also provided at the end of the movable frame 2.

[0036] Both ends of the baffle 2b are provided with elastic elements 2b1, and the end of the movable frame 2 is provided with a positioning groove that cooperates with the elastic elements 2b1.

[0037] It should be noted that the assembled setup of the movable frame 2, the receiving frame 2a, and the baffle 2b allows for the stable placement of concrete specimens while facilitating easy removal by staff for replacement or further maintenance.

[0038] After the push-pull assembly extends the movable frame 2, the operator can remove the baffle 2b by pressing the elastic element 2b1, placing the concrete specimen at the receiving frame 2a. The same procedure applies when the concrete specimen needs to be removed, facilitating the handling and curing of the concrete specimen. Furthermore, the receiving frame 2a allows for easy removal and cleaning of the concrete specimen after curing, facilitating the curing of the next batch of concrete specimens.

[0039] Furthermore, since the concrete specimen has a certain weight, after the baffle 2b is removed, the movable setting of the receiving frame 2a can cooperate with the machine to realize the removal of the concrete specimen.

[0040] See Figure 2-4 As shown, two guide rails 1c are fixedly installed on the rear side of the outer frame 1. The two guide rails 1c are located at both ends of the push frame 1b. The ends of the push frame 1b extend vertically to the inside of the guide rails 1c and can move along the extension direction of the guide rails 1c.

[0041] It should be noted that the guide rail 1c can provide guidance for the movement direction of the push frame 1b, and at the same time prevent the push frame 1b from deviating during movement and causing compression on the end of the telescopic cylinder 1a, thereby improving the stability of the entire push-pull assembly during operation.

[0042] See Figure 1 and Figure 4 As shown, each of the movable frames 2 has a sliding part extending laterally on both sides, and a sliding groove that cooperates with the sliding part is horizontally recessed on the inner wall of the inner side of the outer frame 1.

[0043] The portion of the outer frame 1 located at the bottom inner wall of the sliding groove extends laterally to the bottom of the movable frame 2 to form a support portion. Both the support portion and the sliding portion are symmetrically arranged about the plane containing the axis of symmetry of the movable frame 2.

[0044] It should be noted that the sliding part and sliding groove are designed so that the movable frame 2 can only move along the extension direction of the sliding groove, further improving the stability of the movable frame 2 during the pushing and pulling process. The support part is designed to improve the support of the movable frame 2 for the receiving frame 2a and the concrete specimen inside it.

[0045] See Figure 1 and Figure 6 As shown, the bottom of the receiving frame 2a is set with a grid, and both sides of the outer frame 1 are equipped with highly visible isolation mesh panels 1d.

[0046] The side view of the movable frame 2 is L-shaped, and the working height of the baffle 2b is higher than that of the receiving frame 2a.

[0047] It should be noted that the mesh plate at the bottom of the receiving frame 2a can drain water, and its "L"-shaped arrangement with the side view of the movable frame 2 and its cooperation with the isolation mesh plate 1d allow the staff to observe the curing process of the concrete specimen from different angles without removing the baffle 2b.

[0048] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
