Problems solved by technology

[0002] At present, in the construction industry, the traditional construction of waterstops for toilets, kitchens, etc. that require moisture-proof waterstops are all made of on-site vertical shell molds and concrete pouring. Wood is easy to deform, and there are also disadvantages such as time-consuming and labor-intensive wet work on site, and long construction period.

Embodiment 1

[0012] Embodiment 1, the high-grade concrete solid brick of the present invention and special cement can make finished product in factory in advance. Among them, the proportion of high-grade concrete solid bricks is (by weight): 30 parts of ordinary 32.5R Portland cement, 40 parts of stones (3-10mm in particle size), 20 parts of yellow sand (medium-coarse is better) , 1 part of water reducing agent (such as polycarboxylic acid series water reducing agent), 1 part of waterproofing agent (such as silicone waterproofing agent), mix and stir all the raw materials, and place them in the concrete forming machine to make concrete solid bricks. The proportion of special cement is (by weight): 45 parts of low-alkali sulfoaluminate cement, 45 parts of fine sand, 1 part of water-repellent (such as silicone water-repellent), water-reducing agent (such as polycarboxylic acid series water-repellent) 1 part of water agent), 0.1 part of hydroxypropyl methylcellulose, 0.1 part of redispersible...

Embodiment 2

[0014] Embodiment 2, the construction method of this example and example 1 is the same, only the raw material ratio of high-grade concrete solid brick and special mortar is different. Among them, the proportion of high-grade concrete solid bricks is (by weight): 25 parts of ordinary 42.5R Portland cement, 50 parts of gravel (3-10mm in particle size), 25 parts of yellow sand (medium coarse), water-reducing 3.5 parts of water-repellent, 4.5 parts of waterproofing agent; the proportion of special cement is (by weight): 35 parts of low-alkali sulfoaluminate cement, 60 parts of fine sand, 4.5 parts of waterproofing agent, 3.5 parts of water-reducing agent, hydroxypropyl 0.3 parts of methyl cellulose, 0.55 parts of redispersible latex powder, and 0.55 parts of air-entraining agent.

Embodiment 3

[0015] Embodiment 3, the construction method is the same as Example 1, wherein, the proportioning of the high-grade concrete solid brick is (by weight): 20 parts of ordinary 52.5R Portland cement, 60 parts of stones (3-10mm in particle size), 60 parts of yellow 30 parts of sand (medium coarse), 6 parts of water reducing agent, 8 parts of waterproofing agent; the proportion of special cement is (by weight): 25 parts of low-alkali sulfoaluminate cement, 75 parts of fine sand, 8 parts of waterproofing agent 1 part, 6 parts of water reducer, 0.5 part of hydroxypropyl methylcellulose, 1 part of redispersible latex powder, 1 part of air-entraining agent.

Abstract

The invention discloses a construction method for using a water-stop belt at dampproof water-stop locations, comprising the steps: manufacturing in advance high-grade concrete solid bricks and designated clay, taking the high-grade concrete solid bricks as a main body material on a construction site, and taking the designated clay with fast hardening, micro-expansion and waterproof performances as the water-stop belt of a bonding material for building the dampproof water-stop locations, hence, the invention changes the conventional building concept, has lots of advantages of industrialized production, building-site installation, great easiness and rapidity, stable quality, labor and materials saving, shortened construction period and the like, and also has, compared with the prior art, quite outstanding characteristics and prominent progress.

Description

technical field [0001] The invention relates to a construction method of a water-stop belt used for moisture-proof and water-stop, which is mainly used in toilets, kitchens and other places where moisture-proof and water-stop treatment is required, and belongs to construction technology. Background technique [0002] At present, in the construction industry, the traditional construction of waterstops for toilets, kitchens, etc. that require moisture-proof waterstops are all made of on-site vertical shell molds and concrete pouring. Wood is easy to deform, and there are also disadvantages such as time-consuming and labor-intensive wet operations on site, and long construction periods. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art, and provide a brand-new construction method of a water-stop belt for moisture-proof and water-stop places, which is simple, fast, stable in quality, and labor-saving. [0004] T...
