It is usually made by mixing cement, fine aggregate (sand), coarse aggregate (gravel) and water in a certain proportion, shaping in a mold and curing under specific conditions. The compressive strength of concrete test block is an important indicator of concrete quality. Through compression test, it can be determined whether the concrete meets the design requirements, thereby ensuring the safety and durability of construction projects.

[0003] According to the patent with announcement number CN220271036U, a concrete quality detection equipment includes a device shell, a gate plate is slidably connected to the inside of the device shell to divide the inner cavity of the device shell into a concrete block forming cavity and a test cavity, a first hydraulic rod is fixedly installed at the top end of the device shell, the output end of the first hydraulic rod is drivingly connected to a first pressing plate that enters the concrete block forming cavity, a second hydraulic rod is fixedly installed at the left side of the device shell, the output end of the second hydraulic rod is drivingly connected to a push plate that enters the concrete block forming cavity, a concrete injection inlet with a valve is communicated to the bottom end of the device shell, and a concrete mold cavity is enclosed between the push plate, the gate plate, the first pressing plate and the device shell.

[0004] In the above scheme, the pressure test of the concrete test block is carried out in the inner part of the device shell, which still has the following disadvantages: when the pressure test of the concrete test block is carried out, the concrete test block is always in the inner part of the device shell, and the surface of the device shell does not have a window for observing the test results, which may result in poor intuitiveness of the test results. UTILITY MODEL CONTENTS

[0006] In order to achieve the above utility model purposes, the utility model adopts the following technical scheme: a recycled concrete test block mold for pressure test, including test table, the top surface of test table is equipped with mold groove, the top surface of test table is equipped with test groove, the inside of test groove is detachably provided with sealing plate, the top surface of test table is fixedly provided with installation flap, the top surface of installation flap is fixedly provided with hydraulic cylinder, the top surface of installation flap is slidably inserted with the extension rod of hydraulic cylinder, and the bottom surface of hydraulic cylinder extension rod is fixedly provided with pressing plate.

[0007] Preferably, two limiting grooves are arranged on one side of the inner part of the test groove, two limiting strips are fixed on one side of the sealing plate, the limiting grooves and the limiting strips are slidably arranged, and two elastic strips are fixed on one side of the sealing plate.

[0008] Preferably, a fixing hole is arranged on the top surface of the pressing plate, a pressure sensor is arranged in the fixing hole, a PLC controller is arranged on one side of the mounting flap, and a display is arranged on one side of the mounting flap.

[0009] Preferably, two supporting flaps are fixed on the bottom surface of the test table, a storage frame is slidably arranged between the two supporting flaps, and handles are fixed on the two sides of the storage frame.

[0010] Preferably, rotating columns are fixed on the two sides of the supporting flap, blocking plates are rotatably arranged on the rotating columns, and blocking columns are fixed on the two sides of the supporting flap.

[0011] Preferably, universal wheels are fixed at four corners of the bottom surface of the storage frame, and slopes are fixed on the two sides of the supporting flap.

[0012] Compared with the prior art, the pressure test regenerative concrete test block mold has the following beneficial effects:

[0013] Firstly, the sealing plate is fixed on one side of the inner part of the test groove, the limiting strips are slidably arranged in the limiting grooves, and the elastic strips are tightly attached to the inner wall of the test groove, so that the mold groove forms a square hollow groove with only the upper part being open. Then, the worker pours the concrete into the mold groove, waits for the concrete in the mold groove to solidify, and then removes the mold. Then, the concrete test block is pushed into the test groove below the hydraulic cylinder, the hydraulic cylinder is started, the hydraulic cylinder rod moves downward and presses on the top surface of the concrete test block, and the pressure test of the concrete test block is completed. During the test, the hydraulic cylinder rod pressing on the top surface of the concrete test block exerts the same force on the pressure sensor, the pressure sensor senses the pressure and sends the pressure to the PLC controller, and then the PLC controller sends the information to the display. The concrete test block is exposed to the external environment during the pressing process, which can increase the intuitiveness of the test results.

[0014] II. The concrete test block after pressure test may be broken, and the broken concrete pieces can be discharged from the inside of the test tank through the discharge port and fall into the inside of the storage frame, so that the broken concrete pieces can be recycled. When the inside space of the storage frame is filled with concrete pieces, the worker rotates the blocking plate clockwise, so that the blocking plate is separated from the side of the storage frame. Then the worker pushes the storage frame through the handle, so that the storage frame is pushed away from the two support flaps through the universal wheel and the slope. Through recycling of the concrete pieces, waste of concrete is avoided. BRIEF DESCRIPTION OF DRAWINGS
