Embodiment 1

[0038] Such as figure 1 with 2 As shown, the concrete test block manufacturing device of the present invention includes a mounting base plate 1, a controller 10, a vertical slide bar 6, a flat pressing mechanism, a mold cavity 8, a mold cavity receiving platform, a lifting hydraulic cylinder 4, and a vibration mechanism . Wherein, the controller 10 is preferably implemented by using an existing mechanical control switch capable of outputting multiple control voltages in this embodiment, so this specification does not describe the structure of the controller 10 in detail. The controller 10 is respectively connected with the lifting hydraulic cylinder 4, the flat pressing mechanism and the vibrating mechanism, and controls the working states of the lifting hydraulic cylinder 4, the flat pressing mechanism and the vibrating mechanism.

[0039] During specific implementation, the installation substrate 1 can be fixed on the ground or on a preset slide plate for easy movement, wh...

Embodiment 2

[0046] The only difference between this embodiment and Embodiment 1 is that, as figure 1 As shown, a vibrator 2 is arranged on the lower surface of the platform 20 , and the controller 10 is connected to the vibrator 2 . The vibrator 2 can effectively reduce the gap between the concrete components and increase the density of the test block; at the same time, it can effectively eliminate the air bubbles on the contact surface between the concrete test block wall and the test mold cavity, avoid honeycomb and pitting, and improve The smoothness of the wall surface of the test block.

Embodiment 3

[0048] The implementation method of the concrete test block manufacturing device specifically comprises the following steps:

[0049] Step 1: Apply a layer of release liquid on each inner wall of the test cavity 8, and pour concrete into the test cavity 8 for the first time. Described release liquid is waste engine oil or release agent, and the type of release liquid can be set according to actual conditions, and the first time concrete pouring amount is 1 / 2 of the volume of trial mold cavity 8.

[0050] Step 2: Rotate and lower the vibrating mechanism, insert the vibrating rod 18 of the vibrating mechanism into the concrete in the test mold cavity 8 until the bottom of the test cavity 8 is 2 to 3 cm away, start the vibrating pump 13 to vibrate the concrete, and rotate the slide at a uniform speed. The seat 9 and the slider 17 move at a constant speed to vibrate the concrete from outside to inside for 30-40 minutes.

[0051] Step 3: After the vibration is completed, move the ...

Abstract

The invention discloses a concrete test block manufacturing device. The concrete test block manufacturing device comprises a mounting base plate (1), a controller (10), a mold cavity bearing table, alifting hydraulic cylinder (4), a vibration mechanism and the like. The invention further discloses an implementation method of the concrete test block manufacturing device. The implementation methodcomprises the steps that the inner walls of a mold testing cavity (8) are coated with a layer of mold releasing liquid, and first-time concrete pouring is carried out on the interior of the mold testing cavity (8); and the vibration mechanism is rotated and lowered, and a vibration rod of the vibration mechanism is inserted into concrete in the mold testing cavity to the position 2-3cm away from the bottom of the mold testing cavity. According to the concrete test block manufacturing device and the implementation method thereof, mold releasing can be well completed through the lifting hydraulic cylinder, during use, the mold testing cavity is lifted upwards through the lifting hydraulic cylinder, a formed test block is firmly pressed through a pressing plate of a flat pressing mechanism, the mold testing cavity can be separated from the test block, and the integrity of the test block is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of concrete testing, in particular to a concrete testing block manufacturing device and an implementation method thereof. Background technique [0002] The production ratio of concrete needs to be in accordance with the national concrete production ratio standard, and concrete impermeability performance, frost resistance critical strength and other tests must be carried out during production. During the test, it is necessary to sample no less than once for every 100 trays of concrete mixed with the same mix ratio and no more than 100m3. The sampled concrete was made into standard test blocks for testing. The current test block production method is the mechanical vibration method to tamp the concrete test block, that is, the concrete mixture is filled with the test mold at one time, and the concrete mixture is preliminarily compacted with a vibrating rod to make the concrete mixture higher than the test mold...
