Description

Technical Field

[0001] The utility model relates to the technical field of building material curing equipment, in particular to a building material curing box and its system. Background Art

[0002] After building materials such as concrete / cement mortar are poured, if the climate is hot and the air is dry, and curing is not carried out in time, the water in the concrete / cement mortar will evaporate too quickly, forming a dehydration phenomenon, which will cause the cement particles that have formed a gel body to not be fully hydrated and cannot be converted into stable crystals, lacking sufficient adhesion, resulting in flaky or powdery peeling on the surface of the concrete / cement mortar; at the same time, when the concrete / cement mortar does not yet have sufficient strength, premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the initial curing work after the concrete / cement mortar is poured is very important.

[0003] During the curing process, a constant temperature and humidity environment needs to be maintained inside the box. However, the existing curing boxes generally adopt multiple subsystems such as electric heating tube systems, air-conditioning compressor systems, and humidification systems, resulting in a complex structure of the curing box, high costs, and large energy consumption as multiple systems work independently.

[0054] Embodiment 1

[0055] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 shown, a building material curing box, the building material curing box includes: a square frame formed by connecting a plurality of first cross beams 101 and first vertical beams 102 with a hollow structure, a plurality of drawers 2 for placing test blocks 14, an inner sheet metal 3, a heat insulation layer, an outer sheet metal 4, and a wind baffle 15;

[0056] A plurality of the drawers 2 are sequentially slidably arranged in the square frame from top to bottom;

[0057] The inner sheet metal 3 is embedded in the hollow structure on the square frame to form a sealed square frame 1;

[0058] The outer sheet metal 4 is arranged on the side of the square frame 1;

[0059] The heat insulation layer is arranged between the inner sheet metal 3 and the outer sheet metal 4;

[0060] The outer sheet metal 4 at the top of the square frame 1 is provided with an air inlet 5, and correspondingly, the other outer sheet metal 4 of the square frame 1 is provided with an air outlet 16;

[0061] The air inlet 5 and the air outlet 16 are provided with a wind baffle 15 for uniformly introducing air into the square frame 1 at corresponding positions.

[0062] The present utility model can ensure that the heat dissipation inside the square frame 1 is minimized and in a constant temperature state to the greatest extent by providing a heat insulation layer between the inner sheet metal 3 and the outer sheet metal 4. A plurality of drawers 2 for placing test blocks 14 are arranged on each square frame 1, and multiple test blocks 14 can be cured at one time, improving the curing efficiency. At the same time, the curing box described in the present utility model has a simple structure and does not require complex design. Just input air that meets the temperature requirements through the air inlet 5 on the outer sheet metal 4 at the top of the square frame 1, and the square frame 1 can be in a constant temperature state through the heat insulation layer.

[0063] During use, the staff pulls out the drawer 2 by hand, then places the test block 14 in the drawer 2, and then pushes the drawer 2 back into the square frame 1. At this time, the inside of the square frame 1 is in an environment with good sealing and has a heat preservation function. At this time, air that meets the temperature requirements is conveyed from the air inlet 5. After the air enters from the air inlet 5, it passes through the air separation plate 15 to make the air speed in the square frame 1 uniform, so as to ensure that the temperatures of the test blocks 14 in the same square frame 1 are the same. The conveyed air has a certain humidity, so that the environment in the square frame 1 is in a constant temperature and humidity state.

[0064] Since the traditional curing room has a large space and many test blocks, the temperature control equipment and humidity adjustment equipment need to have a large power. To achieve and maintain the hardening conditions, a large amount of time and electricity are consumed. At the same time, it is difficult to unify the temperature and humidity in all parts of the space. The farther away from the temperature control equipment and humidity adjustment equipment, the less the environment where the test block is located meets the hardening conditions, and defective products are likely to be produced. In addition, to ensure the use safety of the curing room, it is necessary to ensure that the curing room has good heat resistance and moisture resistance, and the curing cost is high. The utility model adopts a multi-layer drawer setting, which can ensure that the concrete with the same curing duration is on the same layer, and the test blocks with different curing times do not interfere with each other, and the temperature and humidity are not affected by loading and unloading the test blocks. Compared with the traditional one, the curing box of the utility model is especially suitable for automation and reduces the requirements for the site.

[0065] In this embodiment, the interaction between the curing box and the outside world is realized in the form of the drawer 2. Under normal circumstances, it can be used for manual handling, and at the same time, it also has the possibility of automation (using industrial robots), and the constant temperature and humidity curing work of the test block 14 can be effectively carried out. The test block 14 is a building material such as concrete or cement products.

[0066] In a specific embodiment, the first cross beam 101 and the first vertical beam 102 of the square frame are manufactured by using 40*40 stainless steel square tubes, which meet the characteristics of a high humidity curing environment. The square frame is welded to provide a basis for the support and connection of the inner layer sheet metal 3, the heat preservation layer and the drawer 2.

[0067] The square frame is formed by welding the first cross beam 101 and the first vertical beam 102. By nesting the inner layer sheet metal 3, the inner layer sheet metal 3 is in the form of a steel plate 12 bent, and its connection with the square frame adopts a laser welding method, which can effectively reduce the welding deformation and improve the sealing performance. The inner layer sheet metal 3 is manufactured by using stainless steel material, which meets the characteristics of a high humidity curing environment.

[0068] In this embodiment, after the inner layer sheet metal 3 is welded to the square frame, a square frame is formed. The heat preservation layer is cut according to the size of the square frame, and after cutting, it is directly nested into the square frame. The heat preservation layer is manufactured by using an extruded plastic board, which has the characteristics of low density and good heat preservation performance.

[0069] In a specific embodiment, two chutes 8 are provided on both side surfaces of the drawer 2; the direction of the chute 8 is the same as the pulling direction of the drawer 2;

[0070] Correspondingly, rollers 9 that are correspondingly matched with the chutes 8 are provided on the first vertical beam 102 of the square frame;

[0071] A handle 10 is provided on the front side wall of the drawer 2.

[0072] The handle 10 is used for manually pulling the drawer 2 by a person, or for grasping the handle 10 by an industrial robot to realize the pulling of the drawer 2. As Figure 1 、 Figure 4 、 Figure 5 As shown, in this embodiment, the drawer 2 is also a drawer 2 formed by welding channel steel, and its top, bottom, and side walls are all hollow structures, which is beneficial to air circulation. Of course, the drawer 2 is of a sealed structure.

[0073] In this embodiment, each side surface of the drawer 2 is composed of two chutes 8, and correspondingly, rollers 9 that are correspondingly matched with the chutes 8 are provided on the first vertical beam 102 of the square frame. The rollers 9 are rotatably arranged in the chutes 8 of the drawer 2. In this embodiment, using the rollers 9 is beneficial to reducing the friction between the rollers 9 and the chutes 8 of the drawer 2. As Figure 6 、 Figure 7 shown.

[0074] In a specific embodiment, as Figure 8 、 Figure 9 、 Figure 10 shown, a placement plate for placing the test block 14 is provided at the bottom of the drawer 2;

[0075] The placement plate is located at one end of the front side wall of the drawer 2;

[0076] The size area of the placement plate accounts for at least half of the bottom area of the drawer 2;

[0077] When the drawer 2 is in the fully pulled-out state, the placement plate is completely exposed outside the square frame.

[0078] If the drawer 2 is in the fully pulled-out state and its whole body is completely exposed outside the square frame, and at this time if the drawer 2 is filled with test blocks 14, due to the large weight of the test blocks 14, the stress points of the drawer 2 and the square frame 1 are under very large stress, and it is easy to cause the drawer 2 or the square frame 1 to deform; therefore, as Figure 4As shown, in this embodiment, the length of the drawer 2 exposed from the square frame 1 accounts for two-thirds of the entire drawer 2. That is to say, one-third of the length of the drawer 2 remains inside the square frame 1. When the placement plate of the drawer 2 is filled with test blocks 14, the drawer 2 remaining inside the square frame 1 mainly plays a supporting role.

[0079] In a specific embodiment, as Figure 8 , Figure 9 , Figure 10 shown, the placement plate includes several steel plates 12 with sawteeth 17 and several second crossbeams 11;

[0080] Both ends of the second crossbeam 11 are connected to the two side walls of the drawer 2; several second crossbeams 11 are arranged at equal intervals;

[0081] Both ends of the steel plate 12 are perpendicularly connected to two adjacent second crossbeams 11;

[0082] Among them, the sawteeth 17 of the steel plate 12 face upward and are in contact with the test blocks 14 placed on the placement plate.

[0083] The sawteeth 17 of the steel plate 12 are used to contact the test blocks 14 placed on the steel plate 12 to increase the friction with the test blocks 14, so as to prevent the test blocks 14 from sliding off the drawer 2 during the process of pulling out the drawer 2.

[0084] In this embodiment, the entire drawer 2 is built with No. 5 channel steel and welded with some square tubes and steel plates 12 with sawteeth 17 to meet the placement of the test blocks 14.

[0085] As Figure 11 , Figure 12 shown, the placement plate of the drawer 2 is supported by steel plates 12 with sawteeth 17, which is convenient for the placement and anti-slip of the test blocks 14, and meets the placement of test blocks 14 with different sizes through reasonable arrangement of the spacing. Currently, there are test blocks 14 with sizes of 100*100*100mm, 150*150*150mm, and 150*150*550mm.

[0086] In a specific embodiment, as Figure 2 shown, the front part of the square frame is formed by connecting several first vertical beams 102 at equal intervals;

[0087] When the drawer 2 is in the fully extended state, there are at least three rollers 9 in the chute 8 on each side of the drawer 2;

[0088] Among them, there are at least two rollers 9 in the lower chute 8 on each side, and at least one roller 9 in the upper chute 8 on each side;

[0089] The corresponding roller 9 is arranged on the first vertical beam 102.

[0090] As Figure 2 shown, the front part of the square frame includes four first vertical beams 102, and rollers 9 are arranged at corresponding positions on each first vertical beam 102.

[0091] When the drawer 2 is in the fully extended state, the drawer 2 inside the square frame 1 is also connected to the rollers 9 of three first vertical beams 102. In this embodiment, the "three-point arrangement" form is adopted, which can meet the requirement of support strength when the drawer 2 is pulled out as a whole.

[0092] In a specific embodiment, a first limit protrusion 13 is provided at the top of the rear side wall of the drawer 2; a second limit protrusion 7 for cooperating with the first limit protrusion 13 is connected to the corresponding first vertical beam 102.

[0093] In this embodiment, through the mutual cooperation and restriction of the first limit protrusion 13 and the second limit protrusion 7, it is prevented that the entire drawer 2 is pulled out of the square frame 1 during the process of pulling out the drawer 2.

[0094] In a specific embodiment, as Figure 6 shown, the cross-section of the roller 9 is an isosceles trapezoid; correspondingly, the cross-section of the chute 8 is an isosceles trapezoid that cooperates with the roller 9;

[0095] wherein the top surface of the roller 9 abuts against the inside of the chute 8.

[0096] The cross-section of the chute 8 is an isosceles trapezoid. By adopting the scheme of the chute 8 and the roller 9, the drawer 2 has the function of automatically centering under the action of weight, reducing the shaking during actual use.

[0097] In a specific embodiment, four support feet are provided at the bottom of the square frame 1, and each support foot is provided with a universal wheel 6 with a locking structure. Through the universal wheel 6, the curing box can be carried anywhere.

[0098] In this embodiment, the outer sheet metal 4 mainly considers aesthetics and economy, and is manufactured in the form of carbon steel + baking paint. The connection with the square frame 1 is fixed by screws, which is convenient for the installation of the thermal insulation layer and subsequent maintenance.

[0099] Embodiment 2

[0100] Based on the building material curing box described in Embodiment 1, this embodiment also provides a building material curing system, including the building material curing box described in Embodiment 1 and temperature and humidity control equipment for adjusting the temperature and humidity inside the curing box;

[0101] The air outlet 16 of the temperature and humidity control device is communicated with the air inlet 5 of the square frame rack 1.

[0102] In this embodiment, the temperature and humidity inside the curing box can be controlled only by the temperature and humidity control device.

[0103] Compared with the prior art, the structure of the curing box described in this embodiment is simple and does not require a complex system.

[0104] In this embodiment, the controlled air flows into the curing box through the air inlet 5 and will first pass through the air baffle 15 to disrupt the air and prevent it from directly blowing on the test block 14; when the air flows out of the curing box, it will also first pass through the air baffle 15 to prevent the air from flowing out concentratedly and causing local out-of-control of temperature and humidity.

[0105] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the implementation manners of the present invention.
