Problems solved by technology

[0003] At present, in the production process of concrete wall panels, after pouring concrete slurry, some inner walls in the pouring mold are often not fully filled, and holes will be generated, which will affect the appearance and quality of the product. The existing methods are: 1. One is to increase the residence time of the troweling mechanism, and the vibrating motor on the troweling mechanism is used to vibrate the concrete. The other is to manually use related equipment to vibrate it before troweling, such as using a hammer to hit the outside of the side plate , and then use the troweling mechanism to smooth it, and the two operate independently. The above two methods both restrict the production efficiency and need to be improved. In practice, after the smoothing treatment, there will be more concrete overflowing from the upper end of the pouring mold The material needs to be cleaned manually in the later period, and due to the delay in cleaning time, the concrete has hardened, making cleaning more difficult

Embodiment 1

[0039] A method for processing noise-reducing concrete wall panels, comprising the steps of:

[0040] (1) Mold and reinforcement assembly: Assemble the side plate 100 into a rectangle according to the preset shape, and lay it along the track to form a casting mold. The tracks are located on both sides of the casting mold and are used for railcars (not shown in the figure) For walking, a number of equidistant steel wires are fixed on the inner wall of one end of the casting mold, and the other end of the steel wire passes through the other end of the casting mold and is tensioned by traction equipment;

[0041] (2) Concrete pouring: use a crane to hoist the hopper above the pouring mold and at one end of the pouring mold, open the hopper and evenly pour concrete slurry into the pouring mold. The concrete slurry includes the following raw materials in parts by weight: cement 100 150 parts of silica fume, 20 parts of thickener, 50 parts of gravel, 80 parts of foam particles, 50 p...

Embodiment 2

[0051] The rest are the same as in Example 1, except that the concrete slurry comprises the following raw materials in parts by weight: 110 parts of cement, 170 parts of silica fume, 25 parts of thickener, 60 parts of sand and gravel, 90 parts of foam particles, wood 55 parts of fiber, 15 parts of foam stabilizer, 10 parts of water reducing agent;

[0052] The steam curing process is:

[0053] In the stage of heating up and constant temperature, the steam generator will continuously and evenly release steam to the surface of the concrete to raise the temperature to 40°C. The heating time is 3 hours, the heating rate is 8°C / h, and the temperature is kept for 1.2 hours after reaching the preset temperature, and the humidity is 75%. ;

[0054] In the cooling stage, the release of steam is stopped and the temperature is lowered to normal temperature, wherein the cooling rate is 7°C / h.

Embodiment 3

[0056] The rest are the same as in Example 1, except that the concrete slurry comprises the following raw materials in parts by weight: 120 parts of cement, 200 parts of silica fume, 30 parts of thickener, 70 parts of sand and gravel, 100 parts of foam particles, wood 60 parts of fiber, 20 parts of foam stabilizer, 20 parts of water reducing agent;

[0057] The steam curing process is:

[0058] In the stage of heating up and constant temperature, the steam generator will release steam continuously and uniformly to the surface of the concrete to raise the temperature to 50°C. The heating time is 2 hours, and the heating rate is lower than 11°C / h. After rising to the preset temperature, keep warm for 1.8 hours, and the humidity is 85%;

[0059] In the cooling stage, the release of steam is stopped and the temperature is lowered to normal temperature, wherein the cooling rate is 9°C / h.

[0060] In the present invention, the forming mechanism includes a machine base 1, a vibrati...

Abstract

The invention discloses a processing method of a noise-reducing concrete wallboard, which relates to the technical field of concrete product production, including steps such as mold and steel bar assembly, concrete pouring, vibrating molding, steam curing and post-treatment. The product of the invention is optimized through formula , and introduce materials such as foam particles and foam stabilizers, so that it not only has excellent mechanical properties, but also the foam particles can form closed pores after molding, which increases the resistance of sound transmission and improves the performance of noise reduction; steam During the curing process, by optimizing the process parameters, the hardening process of the concrete is smooth and orderly, which further ensures the quality of the product; and in the forming process, the forming mechanism only needs to be installed on the rail car and walk with the rail car to complete the concrete The pre-vibration, mid-term smoothing and post-cleaning processes do not need to separate the above three processing procedures, which simplifies the production process and improves the convenience of operation and production efficiency.

Description

technical field [0001] The invention belongs to the technical field of concrete product production, and in particular relates to a processing method for noise-reducing concrete wall panels. Background technique [0002] Concrete wall panels are widely used in the construction field. As people's requirements for living quality are getting higher and higher, higher requirements are put forward for the noise reduction performance of wall panels. [0003] At present, in the production process of concrete wall panels, after pouring concrete slurry, some inner walls in the pouring mold are often not fully filled, and holes will be generated, which will affect the appearance and quality of the product. The existing methods are: 1. One is to increase the residence time of the troweling mechanism, and the vibrating motor on the troweling mechanism is used to vibrate the concrete. The other is to manually use related equipment to vibrate it before troweling, such as using a hammer to ...
