Abstract
Ground surface dry concrete ater-casting waterproofing node is the ater-casting antiseepage of clear-water concrete structure and designing, and belongs to the realm of building construction; Ground surface dry concrete ater-casting waterproofing node by after water slightly expanded concrete, additional coiled material, waterproof roll, steel plate water stopper, expanded metal lath, first pouring concrete, surface concrete layer, expanded metal lath and bed course form; After water between slightly expanded concrete and first pouring concrete should be closely knit seamless, after water after slightly expanded concrete construct, arrange one at ater-casting place and add coiled material, then laying water-proof coiled material thereon, re-lay surface concrete layer; The beneficial effects of the utility model are that surface dry concrete ater-casting, ground waterproofing node structure is simple, and waterproof is reliable, can avoid causing clear-water concrete variable color because of ater-casting seepage.
Description
Technical field
Ground surface dry concrete ater-casting waterproofing node is the ater-casting antiseepage of ground surface dry concrete structure and designing, and belongs to the realm of building construction.
Background technology
When groundwater table is higher, easily there is seepage at the position, ater-casting of ground surface dry concrete structure in ground, just in case clear-water concrete ater-casting Nodes generation seepage, then this place's concrete color can be caused to change, and affect the impression quality of clear-water concrete.
Land used surface dry concrete ater-casting waterproofing node can address these problems.
Utility model content
The specific practice of this programme is:
As shown in Figure 1, ground surface dry concrete ater-casting waterproofing node by after water slightly expanded concrete 1, additional coiled material 2, waterproof roll 3, steel plate water stopper 4, expanded metal lath 5, first pouring concrete 6, surface concrete layer 7 and bed course 8 form; On bed course 8 during paving waterproof roll 1, increase the additional coiled material 2 of paving at position, surface dry concrete ater-casting, ground; Before the first pouring concrete 6 of both sides is built, steel plate water stopper 4 is installed, steel plate water stopper 4 after water between slightly expanded concrete 1 and first pouring concrete 6; After water slightly expanded concrete 1 surface consistent with the surfacing of first pouring concrete 6; Water the upper surface of slightly expanded concrete 1 after additional coiled material 2 is shelved on, not bonding with concrete slab, both sides grow seam 200-300 millimeter; Waterproof roll 3 and first pouring concrete 6 are firmly pasted, neither bonding with concrete slab at additional coiled material 2 position, also not bonding with waterproof roll 3; Expanded metal lath 5 is arranged when indwelling ater-casting, when watering slightly expanded concrete 1 after building, is poured in concrete by expanded metal lath 5; Surface concrete layer 7 is on waterproof roll 3.
The strength grade that slightly expanded concrete 1 strength grade should be not less than first pouring concrete 6 is watered after described, preferential recommendation waters the concreting of slightly expanded concrete 1 strength grade higher than a first pouring concrete 6 strength grade grade after adopting, and add appropriate micro-expanding agent, build rear maintenance and must not be less than 7 days.
Described additional coiled material 2 is the waterproof rolls with waterproof roll 3 same specification, homogenous quantities, preferential recommendation cement-based waterproof coiled material, and waterproof roll 3 and basic unit 8 concrete slab firm pasting, during paving waterproof roll 3, the moisture content of bed course 8 is not more than 9%.
Described steel plate water stopper 4 is the plate-type components made with steel plate, fixing on reinforcing bar before concreting.
Described expanded metal lath 5 adopts the steel plate of band mesh to make, and installs before building first pouring concrete 6.
When described first pouring concrete 6 is built by after water the position of slightly expanded concrete 1, by expanded metal lath 5 by first pouring concrete 6 with after water slightly expanded concrete 1 and separate.
Described surface concrete layer 7, adds coiled material 2 on ground, waterproof roll 3 is built after laying.
Described surface dry concrete ater-casting, ground waterproofing node, is characterized in that bed course 8 is built immediately after test slot of foundation.
The beneficial effects of the utility model are that surface dry concrete ater-casting, ground waterproofing node structure is simple, and waterproof is reliable, can avoid causing clear-water concrete variable color because of ater-casting seepage.
Accompanying drawing explanation
Fig. 1 is surface dry concrete ater-casting, ground waterproofing node organigram.
In figure: water slightly expanded concrete after 1-; 2-adds coiled material; 3-waterproof roll; 4-steel plate water stopper; 5-expanded metal lath; The first pouring concrete of 6-; 7-surface concrete layer; 8-bed course.
Detailed description of the invention
Embodiment
Certain surface dry concrete ater-casting, engineering ground waterproofing node as shown in Figure 1, as shown in Figure 1, ground surface dry concrete ater-casting waterproofing node by after water slightly expanded concrete 1, additional coiled material 2, waterproof roll 3, steel plate water stopper 4, expanded metal lath 5, first pouring concrete 6, surface concrete layer 7 and bed course 8 form; On bed course 8 during paving waterproof roll 1, increase the additional coiled material 2 of paving at position, surface dry concrete ater-casting, ground; Before the first pouring concrete 6 of both sides is built, steel plate water stopper 4 is installed, steel plate water stopper 4 after water between slightly expanded concrete 1 and first pouring concrete 6; After water slightly expanded concrete 1 surface consistent with the surfacing of first pouring concrete 6; Water the upper surface of slightly expanded concrete 1 after additional coiled material 2 is shelved on, not bonding with concrete slab, both sides grow seam 200-300 millimeter; Waterproof roll 3 and first pouring concrete 6 are firmly pasted, neither bonding with concrete slab at additional coiled material 2 position, also not bonding with additional coiled material 2; Expanded metal lath 5 is arranged when indwelling ater-casting, when watering slightly expanded concrete 1 after building, is poured in concrete by expanded metal lath 5; Surface concrete layer 7 is on waterproof roll 3.
After to water slightly expanded concrete 1 strength grade be C30, than first pouring concrete, strength grade C25 high one-level, and add appropriate micro-expanding agent, build rear maintenance and must not be less than 7 days.
Additional coiled material 2 is the waterproof rolls with waterproof roll 3 same specification, homogenous quantities, and adopt cement-based waterproof coiled material, with bed course 8 firm pasting, during paving waterproof roll 3, the moisture content of bed course 8 is not more than 9%.
Steel plate water stopper 4 is the plate-type components made with steel plate, fixing on reinforcing bar before concreting.
Expanded metal lath 5 adopts the steel plate of band mesh to make, and installs before building first pouring concrete 6.
When first pouring concrete 6 is built by after water the position of slightly expanded concrete 1, by expanded metal lath 5 by first pouring concrete 6 with after water slightly expanded concrete 1 and separate.
Surface concrete layer 7, adds coiled material 2 on ground, waterproof roll 3 is built after laying.
Surface dry concrete ater-casting, ground waterproofing node, is characterized in that bed course 8 is built immediately after test slot of foundation.
