Description
Technical field
The utility model relates to a kind of basement water-proof concrete bottom plate rear pouring tape Novel water-stop band structure, belongs to building structure percolation-proof, use of leaking, and is applicable to the basement bottom board late poured band waterstop of waterproof requirement.
Background technology
Along with the expansion of modern city scale, urban architecture monomer area is increasing, building height and the degree of depth are also in continuous refreshing, building foundation base areas and length supergage requirement far away, during back-plane design construction, ater-casting quantity obviously increases, and the waterproof effect of waterstop to ater-casting that new-old concrete connects raft position is most important.
Waterstop mode of occupation conventional at present mainly contains following several:
1, buried comb-shape rubber fastening band in, rubber fastening band utilizes its elastomeric property, can produce after water is met in elastic deformation and volume expansion can occur, therefore play robust sealed effect under various load.
2,
troughing plate waterstop, steel plate for sealing water is generally wide at 300 ~ 400mm, each embedding half in new and old concrete.The new and old concrete seaming position in ater-casting is called constuction joint, after increasing steel plate for sealing water, water is run into steel plate for sealing water and cannot be permeated inward again when new and old concrete connects the gap infiltration of batch position, visible steel plate for sealing water has cut off the permeation pathway of water, steel plate for sealing water has one fixed width, also extend the permeation pathway of water, play waterproof object along the gap infiltration between steel plate for sealing water and concrete.
In above-mentioned two kinds of conventional waterstops, for rubber fastening band: rubber and concrete adhesion poor, in conventional construction, again because rubber is soft elastomer, make concrete when building not easily by tamping, therefore concrete joint expand or drying shrinkage, avulse, reverse time, often can occur that rubber fastening band loosens and comes off, so that can Seepage be produced in the higher situation of head pressure.Simultaneously in work progress, owing to there being the reinforcing bar of the stone of many wedge angles and sharp sword in concrete, if rubber fastening band is not slightly noted being punctured, due to plastics and rubber the low 3-5 of tearing strength specific tensile strength doubly, waterstop is once be punctured or isolating, need not great strength, waterstop will oneself be torn, thus causes the sealing performance of waterstop to reduce.
For
shape steel plate water stopper: because steel plate water stopper is arranged on post empiricism seam place, new-old concrete respectively bury half make alter-pouring strips mould plate therefrom separated cause model sheetinstallat reinforce difficulty larger, and when underplate concrete thickness is less, the foreign material cleaning difficulties such as steel plate water stopper lower position ater-casting root concrete, when building as placed concrete, steel plate water stopper bottom casting and compacting of concrete is difficult to accomplish full closely knit, itself there is infiltration hidden danger.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of easy to process, structure simple, install convenient fixing, good water-proof effect, cost economic, is convenient to the basement water-proof concrete bottom plate rear pouring tape Novel water-stop band structure of post empiricism seam formwork, cleaning, concreting.
A kind of basement water-proof concrete bottom plate rear pouring tape Novel water-stop band structure of the present utility model, it comprises the waterstop installed along bottom plate rear pouring tape constuction joint both sides, described waterstop comprises flute profile profiled sheet, band shape steel plate is welded with in the horizontal direction in the middle of the cell wall outside of described flute profile profiled sheet, described band shape steel plate is connected with fixing reinforcing bar, described fixing reinforcing bar two ends are connected with upper reinforcement with base plate lower rebar respectively, the length of the upper bottom wing of described flute profile profiled sheet is unequal, wherein the long wing is arranged on below in the horizontal direction, short limb is arranged on top in the horizontal direction, the tip extension up and down of described flute profile profiled sheet is stretched respectively to outer and is vertically installed with upper and lower outer with upper bottom wing, the underplate concrete and the lower outer edging that are positioned at lower outer place are arranged, the underplate concrete and the interval, upper outer that are positioned at outer place are arranged.
Employing the beneficial effects of the utility model are:
Bottom plate rear pouring tape constuction joint Novel water-stop band end opening concrete cross section and Novel water-stop band bottom wing anti-flat along one outward, gap is left between concrete suitable for reading and the outer anti-edge of Novel water-stop band upper limb, form a structure water stop slot in Novel water-stop band position after concreting completes, utilize groove sealing line block-water effect and waterstop part steel plate dash to form water-proof system.Be applicable to that there is waterproof requirement cast in place reinforced bar and coagulate native bottom plate rear pouring tape constuction joint position waterstop.
Employing the utility model is rational in infrastructure, post empiricism seam position old concrete formwork supporting plate is convenient, when in ater-casting, as placed concrete secondary is built, cleaning is convenient, concreting is simultaneously vibrated easily closely knit, improve ater-casting concrete self-waterproof performance, substantially increase efficiency during young concrete secondary construction in ater-casting.
