Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a cement test block curing device and method at a construction site. Background Art

[0002] Cement test blocks at construction sites are usually placed in standard curing rooms for curing. Due to the large number of curing test blocks, a large construction site often requires several or even dozens of standard curing rooms. The conventional curing method is to arrange workers to place demoulding test blocks directly in curing cabinets and take them out for testing when they are due. This curing method has the following disadvantages:

[0003] First, the sampling workload is large. For multi-layer storage, you need to bend over to get the test blocks on the bottom layer, and you need to raise your hands to get the test blocks on the top layer. Multiple and frequent sampling and placement is very physically demanding.

[0004] Second, there is a certain probability of sampling errors. Since the test blocks have the same appearance, there is a high probability that the test blocks that have not reached the curing period will be taken away prematurely.

[0005] Third, the process requires frequent manual watering to keep the surface moist. Cement curing has extremely high humidity requirements, and watering is often required multiple times a day to keep the surface moist.

[0006] Fourth, the space utilization is insufficient. Even if multi-layer containers are used, due to the height limit of people, the basic function is controlled at around 4 layers, and the utilization rate of the upper layer space is extremely low.

[0007] Therefore, how to provide a construction site cement test block maintenance device and method is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0008] Aiming at the problems of low efficiency and irregular curing environment in traditional concrete test block curing, a device and method for curing cement test blocks at construction site are proposed. The method adopts a multi-layer cargo curing system to achieve 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.

[0009] In order to solve the above technical problems, the present invention includes the following technical solutions:

[0013] The maintenance system comprises a test block bin and a cable. The test block bin comprises a box body and a partition. The partition is arranged in the box body at intervals. A drainage hole is arranged at the bottom of the test block bin. One end of the cable is fixed to the junction of the load-bearing rod and the tie rod, and the other end of the cable is fixed to the partition.

[0014] A spray system, the spray system comprising a water source, a pump, a water inlet pipe and a spray port, the pump being started at a fixed time for spraying;

[0015] The power system includes a power supply, a driving gear, a transmission belt, a passive gear, and a timer. The timer sets the power start time. When the specified time is reached, the power starts to automatically control the driving gear to rotate, and the passive gear is rotated through the transmission belt, thereby rotating the rotating shaft.

[0016] 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.

[0017] Furthermore, the support column, base and main shaft adopt a full steel structure, and the main shaft can bear the weight of 6 test block bins and load-bearing rods.

[0018] Furthermore, the cable is a steel wire rope, and both ends of the steel wire rope are fixed by drilling holes and forming a straight knot.

[0019] The present invention also provides a method for curing cement test blocks at a construction site, the method comprising the following steps:

[0020] Step S1, providing the construction site cement test block curing device for standby;

[0021] Step S2: The maintenance personnel place the test block in the maintenance bin;

[0022] Step S3: according to the maintenance cycle, set a regular rotation cycle so that when the maintenance cycle is reached, the maintenance bin returns to its original position;

[0023] Step S4: according to the spraying requirements, a reasonable spraying interval is set. After the setting is completed, the spraying system automatically sprays. During the spraying process, the entire device automatically and slowly rotates one circle based on the rotating axis to ensure that all test blocks are sprayed;

[0024] Step S5: After the curing time of the test block is reached, the curing personnel take away the test block that has been cured in the curing bin;

[0025] Step S6, repeating steps S2 to S5 until the protective maintenance of all test blocks at the construction site is completed.
