[0002] Concrete strength test is an important test method for judging whether the reinforced concrete structure reaches the predetermined strength in building engineering, and the concrete strength test is generally carried out by carrying out axial compression test on a concrete square test block with a side length of 150mm. For actual engineering, at least three concrete test blocks of the same batch need to be reserved according to the specification requirements for each pouring operation, and standard steam curing work is carried out.

[0033] As shown in Figures 1-10 The technical scheme of the present application provides a concrete test block standard curing chamber, comprising: a standard curing chamber box shell 1, which is a closed box structure, a first partition plate 14 and a second partition plate 15 are arranged in the standard curing chamber box shell 1 and are parallel to each other, the first partition plate 14 and the enclosed space of the standard curing chamber box shell 1 form an entering sub-compartment 101, the second partition plate 15 and the enclosed space of the standard curing chamber box shell 1 form a receiving sub-compartment 102, the common enclosed space of the first partition plate 14, the second partition plate 15 and the standard curing chamber box shell 1 forms a standard curing compartment 103, and the wall in the entering sub-compartment 101 and the receiving sub-compartment 102 of the standard curing chamber box shell 1 is respectively provided with a first heat preservation door 12 and a second heat preservation door 13; a plurality of matrix arranged test block slide rails 3, which are beam-shaped structures with flat upper surfaces, are fixedly inclined in the standard curing compartment 103, the two ends of the test block slide rails 3 respectively abut against the first partition plate 14 and the second partition plate 15, and the end of the test block slide rails 3 abutting against the first partition plate 14 is higher than the other end of the test block slide rails 3, the concrete test block 6 slides along the test block slide rails 3 under its own weight, the first partition plate 14 and the second partition plate 15 are provided with test piece through ports 16 at positions corresponding to the ends of the test block slide rails 3, and each test piece through port 16 is matched with a closable heat preservation box door 161; a heating and humidifying device 5 is installed in the standard curing compartment 103.

[0034] In the technical solution, the support of the steel structure is fixed below the bearing bottom plate 11 of the curing chamber box shell 1, which facilitates the overall lifting and hanging of the curing chamber box shell 1 and the internal various equipment, the sizes of the first thermal insulation door 12 and the second thermal insulation door 13 can allow the construction personnel to enter by using a board cart or other simple on-site transportation tools, the space of the entering sub-chamber 101 and the receiving sub-chamber 102 allows the construction personnel to store and take out the concrete test blocks 6 inside, after the construction personnel put the concrete test blocks 6 from the test piece through port 16 on the first partition plate 14, the concrete test blocks 6 enter the curing chamber 103 and slide down along the test block slide rail 3 under the action of gravity until they are stopped by the thermal insulation box door 161 on the second partition plate 15, the subsequent concrete test blocks 6 put in from the test piece through port 16 are arranged in sequence on the same test block slide rail 3 in the curing chamber 103, when the first concrete test block 6 put in on the test block slide rail 3 reaches the age, the operator opens the corresponding thermal insulation box door 161 on the second partition plate 15, takes out the concrete test block 6, and then closes the thermal insulation box door 161, and other concrete test blocks 6 are simultaneously slid into place, and the upper part of the test block slide rail 3 is empty and can accommodate new concrete test blocks 6.

[0035] In the technical solution, the heating and humidifying device 5 inside the curing chamber 103 is a temperature control device or a combination of multiple devices available on the market, including but not limited to various electric heating wires, electric heating pipes, hot water pipes, and spray pipes, etc. The electric external interface of the above-mentioned devices needs to be specially treated or set outside the curing chamber 103 to avoid circuit short circuit and failure under the condition of long-term high temperature and high humidity.

[0036] In the technical solution, the operator only needs to record the test piece through port 16 of each concrete test block 6, and can mark the thermal insulation box door 161 on the first partition plate 14 and the second partition plate 15 for easy searching. This arrangement not only reduces the space for personnel searching and operation in the conventional curing chamber, improves the storage space of the concrete test blocks 6, but also greatly facilitates personnel management and searching. The operator enters the entering sub-chamber 101 and puts the concrete test blocks 6 or the cage with the concrete test blocks 6 into the test piece through port from this side, and the concrete test blocks 6 slide along the high end of the test piece slide rail 3 to the bottom end under the action of gravity. When the concrete test blocks 6 reach the test age, the operator enters from the receiving sub-chamber 102, and the taken-out concrete test blocks are necessarily arranged in sequence according to the time of putting in, and the taken-out concrete test blocks 6 are necessarily the earliest to reach the test age condition, and the management efficiency is greatly improved. Taking a concrete test block curing chamber with 28 test piece slide rails 3 and each slide rail capable of accommodating 15 concrete test pieces 6 as an example, it can meet the curing needs of at least 20W㎡ concrete engineering concrete test blocks 6, and can be transported with a trailer and can be used for curing work of concrete test blocks 6 of multiple engineering projects.

[0037] In another technical solution, the test block slide rails 3 are arranged in vertical rows at intervals, and both ends of all the test block slide rails 3 are aligned and parallel to each other. Each vertical row of test block slide rails 3 is fixed on a single storage rack 21 at intervals, and the single storage rack 21 is fixed in the standard curing chamber 103. In this technical solution, all the test block slide rails 3 are fixed on the test block storage rack 2. The test block storage rack 2 can be an integral frame structure, or it can be composed of multiple single storage racks 21. The single storage rack 21 needs to be connected to the inner bottom of the standard curing chamber shell 1.

[0038] In another technical solution, the test block slide 3 includes two parallel and opposite track frame beams 31, the track frame beams 31 are connected to the single-frame storage rack 21, and a number of rollers 32 are rotatably connected between the opposite track frame beams 31. The interval between adjacent rollers 32 is less than half of the side length of the concrete test block 6. The rows of rollers 32 can enable the concrete test block 6 to slide on the test block slide 3. The small interval between the rollers 32 prevents the concrete test block 6 from flipping or rolling during the sliding process. The rollers 32 and the axial nodes connected to the track frame beams 31 are made of high temperature and high humidity resistant materials. The track frame beam 31 is fixed to the single-frame storage rack 21 by bolts or welding.

[0039] In another technical solution, each track frame beam 31 is connected upward with a side limit plate 33, and the spacing between the relative side limit plates 33 is greater than the side length of the concrete test block 6. The side limit plates 33 limit the horizontal displacement of the concrete test block 6 during the sliding process, preventing the concrete test block 6 from sliding out of the test block slide rail 3 from the side. Under ideal conditions, the spacing between the two relative side limit plates 3 does not exceed 1.5 times the side length of the concrete test block 6, thereby preventing the concrete test block 6 from rotating.

[0040] In another technical solution, the curing chamber 103 is provided with an inner partition 4, all the test block sliding rails 3 are located on one side of the inner partition 4, and the heating and humidifying device 5 is installed on the other side of the inner partition 4. The heating and humidifying device 5 comprises a fan 53, a humidifying pipe group 52 and a heating pipe group 51. The inner partition 4 is provided with an air inlet 41 and an air return 42. The fan 53 is connected with a fan motor 531 outside the curing chamber box 1. In this technical solution, the humidifying pipe group 52 is connected with a compressor, a water vapor generator and other devices outside the curing chamber 103. The devices are electrically connected to a control system outside the curing chamber 103 to adjust the humidity in the curing chamber 103. The heating pipe group 51 can be a heating device with circulating hot water in the pipe inside the curing chamber 103, or a conventional heating device such as a heating lamp or a heating wire is used to replace the heating pipe group 51. The curing chamber 103 is a closed space, and the air circulation is achieved by the increased fan 53. When the temperature or humidity is insufficient, the heating pipe group 51 and the humidifying pipe group 52 start to work. The fan 53 sends the air that has been heated and humidified to the area of the test block storage rack 2 through the air inlet 41.

[0041] In another technical solution, the heating and humidifying device 5 further comprises a plurality of spraying devices 54 installed in the curing chamber 103. The spraying devices 54 are connected to a water storage device outside the curing chamber 103 and spray at regular intervals. Optionally, a drainage port or a drainage device is arranged on the ground of the curing chamber 103 to timely drain the excess water in the curing chamber 103.

[0042] In another technical solution, the concrete test blocks 6 are placed in the test block cage 61 in groups of three. The test block cage 61 is a rigid metal cage. The width of the test block cage 61 is equal to the distance between the two opposite side limiting plates 33. In this technical solution, three standard test blocks of the same batch of concrete are usually stored in the test block cage 61 made of metal welding. Since the test block cage 61 is rigid, it can slide more smoothly on the test block sliding rail 3.

[0043] In another technical solution, the curing chamber box 1, the first partition 14 and the second partition 15 are all sandwich type plates composed of two stainless steel plates and an inner thermal insulation layer. The thermal insulation layer is a polyurethane material with a thickness of 80mm-120mm. The thickness of the stainless steel plate is not less than 1mm. The two stainless steel plates are combined and connected by light steel keels or other methods. Finally, a thermal insulation foaming agent is filled to form the inner thermal insulation layer.

[0044] The number of components and the scale of processing described herein are used to simplify the description of the present application. The application, modification and change of the present application are obvious to those skilled in the art.

[0045] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and can be applied to various fields suitable for the present application. Those skilled in the art can easily implement other modifications, and thus the present application is not limited to specific details and the figures shown and described herein, without departing from the general concept defined by the claims and the equivalent scope.
