Problems solved by technology

[0002] The current building partition panels are generally made of bricks, which leads to a longer construction period and heavier walls, which increases the load-bearing level of the building design and further increases the cost.

The use of hollow partition wall panels, although the construction period is fast, the weight is lighter...

Abstract

The invention discloses a constructional partition plate and a preparation method thereof. The partition plate is a hollow plate, the tongue-and-groove is composed of a dovetail tenon and a dovetail groove, the tenon and the groove interlock with each other, and the groove depth is 20 mm. The partition plate is composed of the following components in parts by weight: 15 to 18 parts of cement, 25 to 30 parts of fly ash, 45 to 55 parts of building slag powder, 1 to 2 parts of water reducer, 1 to 2 parts of early strength agent, 2 to 3 parts of waterproof agent, and 2 to 4 parts of demoulding agent. The partition plate has a high compression resistant strength and low surface density, thus the floor bearing is reduced, furthermore, the thermal coefficient of the partition plate is low, and the air soundproof effect of the partition plate is very good, so the partition plate also has a good thermal insulation and soundproof effect.

Example Embodiment

[0016] Example 1

[0017] A kind of partition wall board for construction, the board is a hollow board, the board width is 600mm, the board cross section has 7 round holes side by side, the diameter of the round holes is 58mm; the tongue and groove are dovetail interlocking tenon and tenon groove, tenon groove depth 20mm; the partition wall board is made of the following components in parts by weight: 18 parts of cement, 30 parts of fly ash, 50 parts of construction waste residue powder, 1.5 parts of magnesium lignosulfonate, 2 parts of calcium sulfate, stearin 2 parts of calcium acid and 3 parts of emulsified oil. Wherein, the construction waste slag powder is a powder with a particle size of less than 120 meshes made by at least one of construction bricks, concrete, and industrial slag after initial breaking and ball milling.

[0018] The specific preparation method of the above-mentioned building partition board is as follows: first foaming the proportion of cement, and then adding water to the foamed cement, the proportion of fly ash and construction waste slag powder, and then adding Mix the proportion of water reducing agent, early strength agent and water repellent, and stir for more than 3 minutes to obtain the slurry; then pour the slurry into the mold with the inner frame sprayed with the proportion of emulsified oil, and roll forming at 18~ Cured for 24h at 25℃, finally demoulded and cured at 18~25℃ for more than 7 days.

[0019] The above-mentioned building partition wall panels are used as follows: multiple partition wall panels are vertically spliced into a wall through the dovetail interlocking tenons and tongue grooves of the tongue and groove, and the joints of the tongue and groove can be smoothed and reinforced by cement glue.

[0020] The performance test results of the partition wall panels in the above embodiments are as follows:

[0021]

[0022]

[0023] According to the above test results, the new building partition wall panel of the present invention has high compressive strength, low areal density, reduces floor load, low thermal conductivity, high air sound insulation, and has better heat preservation and sound insulation effects.
