Description

Technical Field

[0001] The utility model relates to the technical field of concrete specimen curing, in particular to a concrete specimen curing box. Background Technique

[0002] The curing of concrete specimens is a key step to increase their strength. It usually takes about one month and requires a curing box to maintain temperature and humidity.

[0003] After retrieval, in the application with the patent application number 202122058209.1, a steam-cured aerated concrete specimen curing box is disclosed, which includes a curing box body. The curing box body is connected with a humidifying system and a temperature control system; the curing box body includes an outer shell and an inner shell. The top of the inner shell has a slope structure with a higher middle and lower surrounding; the inner shell forms multiple curing chambers due to multiple partition plates, and a water diversion plate with an inclined surface in an inverted V-shaped structure is arranged at the top of each curing chamber; a first slope plate and a second slope plate are arranged at the bottom of the inner shell. The bottom of the first slope plate and the bottom of the second slope plate are arranged opposite to each other to form a drainage groove, and a drainage hole is arranged at the bottom of the drainage groove. The water droplets condensed during the humidifying process can flow along the top of the inner shell and the water diversion plate to the slope plates at the bottom of the inner shell and drain out from the drainage hole along the slope plates. Therefore, the humidity can be kept at the maximum value and the specimens absorb moisture evenly, and the deviation generated by each test is small.

[0004] The above application document ensures the drainage effect through the setting of the partition plate and the drainage groove. However, firstly, the water droplets along the box wall still slide down to the inside of the box body and need to be cleaned regularly. The operation is cumbersome and cannot achieve automatic drainage. Secondly, when placing the concrete test blocks, a manipulator needs to be used to place them on the rack inside the box body. The position space of the existing rack is fixed, resulting in a small working space for the manipulator and low practicability.

[0005] Therefore, we propose a concrete specimen curing box. Utility Model Content

[0006] Aiming at the deficiencies of the prior art, the utility model provides a concrete specimen curing box, which solves the problems of low automation degree, cumbersome operation and low practicability of the existing drainage groove output position in the box body and still requires subsequent manual drainage.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions: a concrete specimen curing box, including an outer shell and an inner shell inside it, and a temperature control system and a steam humidifying system are also arranged on the outer wall of the outer shell and are connected to the concrete curing cavity inside the inner shell.

[0008] Both the inner housing and the outer housing include a rectangular box body and an inverted V-shaped top on its top side. There are spaced drainage grooves in the inner housing, and the drainage grooves are arranged on the inverted V-shaped top and the left and right side walls. A drainage frame is fixedly installed at the bottom inside the inner housing. A drainage groove is arranged in the drainage frame, and the output end of the drainage frame is fixedly connected with a drain pipe.

[0009] Preferably, the bottom surface of the drainage groove inside the drainage frame is an inclined bottom surface. The drainage frame is arranged below the drainage groove, and the top side edge of the side of the drainage frame is arranged as an inwardly inclined chamfer shape.

[0010] Among them, the chamfer shape is convenient for the liquid flow to enter the groove in the drainage frame.

[0011] Preferably, a drainage hole is opened at the bottommost side of the inclined bottom surface. The outer end of the drainage hole is fixedly connected with a drain pipe, and a solenoid valve seat is arranged between the drainage hole and the drain pipe.

[0012] Among them, the setting of the drainage frame is convenient for automatically discharging the discharged liquid flow in cooperation with the inclined inner bottom surface, and the setting of the solenoid valve seat can control the drainage time.

[0013] Preferably, a concrete specimen rack is placed inside the inner housing. The main body of the concrete specimen rack is a bottom plate. Four groups of opposite support columns are fixedly installed at the four corners on the top of the bottom plate, and a support plate is movably sleeved on the support columns.

[0014] Among them, the setting of the bottom plate on the concrete specimen rack can sleeve the support plate on it to realize the synchronous assembly of multiple groups of support plates.

[0015] Preferably, four groups of internal screw grooves are arranged at intervals on the outer wall surface of the support column. External screw grooves with the same specifications and opposite positions to the internal screw grooves are arranged on the edge surface of the support plate, and the external screw grooves and the internal screw grooves are assembled through fastening bolts.
