Description

Technical Field

[0001] The present application relates to a cement-based self-leveling filling bonding material and a construction method thereof. Background Art

[0002] Assembled floor heating pipe assembly blocks refer to the method of setting floor heating pipe grooves in the assembly blocks, prefabricating the assembly blocks, and then introducing mortar between the assembly blocks. The introduced mortar needs to have the function of bonding the assembly blocks and filling the gap between the assembly blocks and the ground base. This requires the mortar to have good fluidity, adhesion, and no cracking after drying. The existing mortar can basically meet the above requirements. However, since there are two purposes for using assembly blocks, one is to speed up the construction progress and improve construction efficiency; the other is to be able to replace them when they are damaged or the house is renovated. The existing mortar can generally only bond the products together, and it is actually difficult to separate them when replacing them. Summary of the invention

[0003] In order to solve the above problems, the present application proposes a cement-based self-leveling filling adhesive material, comprising the following raw materials in parts by weight:

[0004] Cement: 180-200 parts;

[0005] Gypsum powder: 4-6 parts;

[0006] Vitrified microspheres: 6-8 parts;

[0007] Glass powder: 8-10 parts;

[0008] Okara: 4-6 portions;

[0009] Cellulose: 0.5-0.8 parts;

[0010] Polycarboxylate ether: 0.3-0.5 parts. The filling adhesive material used in the present application is mainly used for connection between assembly blocks and between assembly blocks and the outside, and needs to be able to play the role of leveling and connection, and after use, it needs to be able to be disassembled for later maintenance and replacement.

[0011] Preferably, the water-to-material ratio of the filling adhesive material is 0.3-0.4:1.

[0012] Preferably, the particle size of the vitrified microspheres is 10-100 μm;

[0013] The cellulose is glass fiber, and the diameter of the glass fiber is 10-20 μm and the length is 2-5 mm.

[0014] Preferably, the glass powder is obtained by crushing silicate glass, and then sieving to obtain particles with a particle size between 20 mesh and 50 mesh.

[0015] Preferably, the bean dregs are obtained in the following manner:

[0016] Soaking and grinding the soybeans and filtering them to obtain a filter residue;

[0017] The filtered residue is dried and then ground through a 200-mesh sieve, and the sieved material is taken to obtain bean dregs. The present application reduces the strength of the filling adhesive material after wetting through the composite effect of bean dregs, vitrified microbeads, and glass powder, making it easier to operate when it needs to be removed, and the glass microbeads and glass powder can play an isolation role.

[0018] Preferably, the flexural strength of the mortar board obtained by pouring the filling adhesive material after being fully moistened is 1 / 3-1 / 2 of that in the dry state.

[0019] On the other hand, the present application also proposes a construction method of a cement-based self-leveling filling adhesive material, comprising the following steps:

[0020] Lay the assembly blocks on the ground and level the assembly blocks;

[0021] preparing a filling bonding material;

[0022] Pour the filling adhesive material into the gap between the lower part of the assembly block and the ground, the gap between the assembly blocks, and the gap between the side of the edge assembly block and the wall;

[0023] After maintenance, install the floor heating pipes on the assembly blocks.

[0024] Preferably, an introduction channel for introducing filling adhesive material is reserved in the middle of the assembly block.

[0025] Preferably, the filling adhesive material is prepared as follows:

[0026] The cement, gypsum powder, vitrified microspheres and glass powder are fully mixed to obtain a first component;

[0027] Adding dregs of soybeans, cellulose and polycarboxylate ether into water and mixing them thoroughly to obtain a second component;

[0028] The first component and the second component are mixed to obtain a filling adhesive material. The present application mixes bean dregs, cellulose, and polycarboxylate ether into water. In this way, the uniformity of the cellulose mixture can be ensured, and the bean dregs and polycarboxylate ether are distributed in agglomerates based on the cellulose. During the synthesis, the strength of the concrete is ensured. In the later stage, the strength of the adhesive material obtained by the filling adhesive material under wet conditions can be reduced, which is convenient for disassembly.

[0029] Preferably, an adjusting bolt for adjusting the height is provided under the assembly block or a bottom supporting leg is provided at the bottom of the assembly block.

[0030] This application can bring the following beneficial effects:

[0031] 1. The filling adhesive material used in this application is mainly used for the connection between assembly blocks and between assembly blocks and the outside. It needs to be able to play a leveling and connecting role, and after use, it also needs to be able to be disassembled for later maintenance and replacement.

[0032] 2. This application reduces the strength of the filling adhesive material after wetting through the composite effect of bean dregs, vitrified microbeads and glass powder, making it easier to operate when removal is required, and the glass microbeads and glass powder can play an isolating role.

[0033] 3. The present application mixes bean dregs, cellulose and polycarboxylate ether into water. In this way, the uniformity of the cellulose mixing itself can be ensured, while the bean dregs and polycarboxylate ether are distributed in clusters based on the cellulose.

In the later stage, the strength of the adhesive material obtained by filling the adhesive material under wet conditions can be reduced, which is convenient for disassembly. DETAILED DESCRIPTION
