Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a concrete test block water curing device and method. Background Art

[0002] Whether the curing environment meets the standards is of great significance to ensuring the quality of materials. Stable water temperature and good water quality must be ensured during the curing of test blocks. At present, concrete water curing has not been taken seriously. Usually, non-professionals are arranged to throw the demoulded test blocks directly into the test block curing pool and control the temperature through external air conditioning. This method has two disadvantages:

[0003] First, the efficiency of single-layer stacking is extremely low. It is only placed at the bottom of the curing pool, and the upper space cannot be used, and the space utilization rate is too low;

[0004] Second, the maintenance environment is not standardized. The water temperature is indirectly controlled by the indoor air conditioner, which has low temperature control efficiency. After artificial water replacement, there is a long-term unstable water temperature stage, which easily leads to a decline in the quality of concrete maintenance.

[0005] Therefore, how to provide a concrete test block water curing device and method is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] Aiming at the problems of low efficiency and irregular curing environment in traditional concrete test block curing, a device and method for water curing of concrete test blocks are proposed. The method adopts a multi-layer cargo-format test block curing box, and realizes three-dimensional and efficient application of the curing box through multi-layer curing. The water temperature and water circulation are guaranteed based on an automatic constant temperature system and a regular water supply device.

[0007] In order to solve the above technical problems, the present invention includes the following technical solutions:

[0008] A concrete test block water curing device, comprising:

[0009] A support frame, the support frame comprising an aluminum alloy frame formed by connecting vertical rods and horizontal rods;

[0010] A test block curing box, at least two of which are vertically spaced apart and placed on the aluminum alloy frame, the test block curing box comprising a box body, a partition and a temperature control system, the partition being fixed at intervals on the side wall of the box body; the temperature control system comprising a temperature controller and a heating wire, the heating wire being fixed to the bottom of the box body and arranged around the bottom of the box body;

[0011] A water inlet system, the water inlet system comprising a water source, a water inlet pipe and a water level control valve, one end of the water inlet pipe is connected to the water source, and the other end is connected to the water level control valve, and the water level control valve is fixed on the side wall of the box;

[0012] A drainage system comprises a drainage pipe and a timed drainage valve.

[0013] Furthermore, the partition divides the box into a 20 cm×20 cm maintenance partition, and a gap is left between the partition and the bottom of the box to ensure that water flows freely in the box.

[0014] Furthermore, the water level control valve includes a water inlet and outlet, a limit track, a hollow buoy, and a spring. The water level control valve is 160 cm away from the bottom of the box. When the water level is lower than 160 cm, water injection begins, and when the water level reaches 160 cm, water injection stops to ensure that the top of the test block is submerged in water.

[0015] Furthermore, the timed drain valve is an electromagnetic valve, which contains a timer, an electromagnet, a spring, and a piston. The timer sets the drainage interval time. When the specified drainage time arrives, the circuit is connected, the electromagnet is energized to generate a magnetic field, which sucks up the piston, thereby draining water; after the drainage time is over, the circuit is closed, the magnetic field disappears, and the piston blocks the water outlet under the action of the spring, and the water flow stops.

[0016] The present invention also provides a method for curing a concrete test block, the method comprising the following steps:

[0017] Step S1, providing the concrete test block water curing device for standby;

[0018] Step S2, the test block curing box is connected to a power source, the water level control valve is opened, water flows into the water inlet pipe, and gradually flows into the curing compartment. The thermostat of the curing box detects that the temperature does not meet the standard, and the electric heating wire at the bottom of the box is automatically heated;

[0019] Step S3: When the water level reaches the designed height, the water level control valve automatically closes, the water flow stops, the thermostat detects that the temperature reaches the standard, the heating wire at the bottom of the box stops heating, and the maintenance conditions are met;

[0020] Step S4, placing the curing test block into the curing compartment in the test block curing box for curing;

[0021] Step S5, the timing drain valve opens to drain water within the specified time, and the water level control valve detects the water level drop and automatically adds water to achieve water quality change;

[0022] Step S6, repeating steps S3 to S5 until the curing of all concrete test blocks is completed.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0024] The present invention provides a concrete test block water curing device and method, comprising a support frame, a test block curing box, a water inlet system and a drainage system, wherein the support frame comprises an aluminum alloy frame formed by connecting vertical rods and horizontal rods; at least two test block curing boxes are vertically spaced and placed on the aluminum alloy frame, the test block curing box comprises a box, a partition and a temperature control system, and the partition is fixed on the side wall of the box at intervals; the temperature control system comprises a thermostat and an electric heating wire, and the electric heating wire is fixed to the bottom of the box and arranged around the bottom of the box; the water inlet system comprises a water source, a water inlet pipe and a water level control valve, one end of the water inlet pipe is connected to the water source, and the other end is connected to the water level control valve, and the water level control valve is fixed on the side wall of the box; the drainage system comprises a drainage pipe and a timed drainage valve. The concrete test blocks are stacked in multiple layers in the test block curing box of the concrete test block water curing device, which can effectively utilize the space of the standard curing room and multiply the curing efficiency. The cargo format design ensures that there is one test block per compartment, avoiding the drawback of disorderly stacking of test blocks, which makes it impossible to quickly locate the specified test block when taking the block. Automatic constant water temperature and water level setting ensures the curing environment, regular water quality replacement, and ensures the quality of concrete curing.

[0034] In this embodiment, more preferably, the partition 5 divides the box into 20 cm×20 cm maintenance partitions, and a gap is left between the partition and the bottom of the box to ensure that water flows freely in the box.

[0035] In this embodiment, more preferably, the water level control valve 4 includes a water inlet 8, a water outlet 9, a limit track 10, a hollow buoy 11, and a spring 12. The water level control valve 4 is 160 cm away from the bottom of the box. When the water level is lower than 160 cm, water injection begins, and when the water level reaches 160 cm, water injection is stopped to ensure that the top of the concrete test block is submerged in water. The working principle of the water level control valve 4 is that the hollow buoy 11 can only slide in one direction under the restriction of the limit track 10. After the water level drops, there is no water in the water level control valve 4, and the hollow buoy 11 is stagnant at the lower part of the valve of the water level control valve 4 under the action of the spring thrust, and the water flow can flow through the gap of the spring 12; after the water level reaches the designed position, the hollow buoy 11 floats up under the action of buoyancy, and the rubber sealing pad blocks the water inlet to stop water from entering the water inlet.

[0036] In this embodiment, more preferably, the timed drain valve is a solenoid valve, which contains a timer, an electromagnet, a spring, and a piston. The timer sets the drainage interval time. When the specified drainage time arrives, the circuit is connected, the electromagnet is energized to generate a magnetic field, which sucks up the piston, thereby draining water; after the drainage time is over, the circuit is closed, the magnetic field disappears, and the piston blocks the water outlet under the action of the spring, and the water flow stops.

[0038] Step S1, providing the concrete test block water curing device for standby;

[0039] Step S2, the test block curing box is connected to a power source, the water level control valve 4 is opened, water flows into the water inlet pipe, and gradually flows into the curing compartment. The thermostat 6 of the curing box detects that the temperature does not meet the standard, and the electric heating wire at the bottom of the box is automatically heated;

[0040] Step S3, the water level reaches the designed height, the water level control valve is automatically closed, the water flow stops, the thermostat 6 detects that the temperature reaches the standard, the heating wire at the bottom of the box stops heating, and the maintenance conditions are met;
