Description
Technical field
The utility model relates to a kind of architectural furniture, particularly the anti-concrete by-pass means of underground continuous wall groove segment H shaped steel joint grouting plate.
Background technology
Under normal circumstances; the topping of the main muscle of diaphragm wall is 50mm～70mm; therefore concrete because the imprecision of protection may produce concrete to stream and enter in H shaped steel and adjacent cells groove section along H shaped steel outside, has caused difficulty to the excavation, punching, cleaning etc. in later stage in the process of perfusion.
For preventing that concrete from streaming and entering in H shaped steel and adjacent cells groove section along H shaped steel outside, the method that construction adopts is at present: at the elongated interior subsides plastic foam plate of H shaped steel scope, and fill sand hill or mud drum; The method has following deficiency:
1, fill sand hill or mud drum engineering quantity is large, labor intensive large and cannot reclaim, cycle engineering time is long, and occupied ground is larger;
2, the thing such as foam, sandbag that remains in H shaped steel wing plate place may cause the seepage of groove section joint;
3, the plastic foam plate that paste H shaped steel both sides can produce buoyancy in the decentralization process of reinforcing cage, and plastic foam plate is easy to floating; And because the buoyancy of both sides is likely unequal, can cause the inclination of reinforcing cage to be difficult for laying;
4, the headroom that has main tendon protective layer due to H shaped steel outside,, often there is concrete and streams phenomenon in the filling protection imprecision of sand hill or mud drum.Affect the construction of adjacent cells groove section.
For solving when ground-connecting-wall is constructed, effectively prevent joint concrete circumferential motion problem, patent announcement number is CN203129188U, utility model name is called: the utility model patent of the anti-by-pass means > of < < underground continuous wall connector > discloses the anti-by-pass means of a kind of underground continuous wall connector, and its mounting method being disclosed: " installs when this diaphragm wall is anti-streams iron sheet 1, two measure-alike iron sheets 1 are chosen in employing, the link 11 use fine steel rib pressure weldings of iron sheet 1 are on the frange plate of the both sides of I shape steel plate for sealing water 3, again the free end of iron sheet 1 12 is distinguished to colligations in the both sides of manufactured reinforcing cage 2, so that transfer reinforcing cage 2 in the interior integral body of groove section 4 of having constructed, after above-mentioned completing, reinforcing cage 2 is arrived in groove section 4 together with iron sheet 1 below, then free end 12 and reinforcing cage 2 are unclamped, to its concreting, " to reach the object of preventing joint concrete to stream.
This device is feasible theoretically, but when practice of construction, this device also has the following disadvantages: the one, and iron sheet 1 is to be welded on the frange plate outside, both sides of I shape steel plate for sealing water 3 (referring to this application Figure of description Fig. 1-Fig. 2, present specification accompanying drawing Fig. 7-Fig. 8), H shaped steel steel plate for sealing water 2 be very greatly, very heavy, iron sheet 1 is all welded on to frange plate outside, both sides, if construct below welding grouting plate in H shaped steel outside, constructs just very inconvenient; If in H shaped steel outside, grouting plate is not welded in construction below, when grouting plate has been welded in construction, H shaped steel steel plate for sealing water need to turn the grouting plate that could weld opposite side, so H shaped steel steel plate for sealing water needs not convenient construction of secondary displacement;
Next during this device construction, is " the 12 difference colligations of the free end of iron sheet 1, in the both sides of manufactured reinforcing cage 2, to be arrived reinforcing cage 2 in groove section 4 together with iron sheet 1 below, then free end 12 and reinforcing cage 2 are unclamped; "; because the diaphragm wall degree of depth is generally more than 10 meters; be very dark very large; and the size of reinforcing cage 2 is basically identical with diaphragm wall groove section to be poured length size; reinforcing cage 2 is being transferred to together with iron sheet 1 in diaphragm wall groove section 4 to be poured; then free end 12 and reinforcing cage 2 are unclamped and can not be accomplished, owing to free end 12 and reinforcing cage 2 can not being unclamped, after concrete perfusion, free-ended the opening in its underpart is limited, can not all open, so the effect that its prevention joint concrete streams is given a discount widely.
Summary of the invention
The purpose of this utility model is to provide a kind of enforceable " the anti-concrete by-pass means of underground continuous wall groove segment H shaped steel joint grouting plate ", to overcome the weak point of the anti-by-pass means > of < < underground continuous wall connector >, when solution is constructed at ground-connecting-wall, effectively prevent underground continuous wall groove segment H shaped steel joint concrete circumferential motion problem.
The technical scheme addressing the above problem is: the anti-concrete by-pass means of a kind of underground continuous wall groove segment H shaped steel joint grouting plate, comprise two blocks of grouting plates that are arranged at respectively on ground-connecting-wall I shape steel plate for sealing water frange plate, described grouting plate one end is fixedly connected with I shape steel plate for sealing water frange plate, the other end is free end, it is characterized in that: wherein a grouting plate is fixedly connected with the inner side of the following frange plate of I shape steel plate for sealing water, another piece grouting plate is fixedly connected with the outside of I shape steel plate for sealing water top frange plate.
The further technical scheme of the anti-concrete by-pass means of described underground continuous wall groove segment H shaped steel joint grouting plate is: described grouting plate is that thickness is that 0.5mm, width K are the galvanized sheet iron that 500～700mm, length are greater than length of reinforcing cage 400～600mm.
Compared with prior art, the anti-concrete by-pass means of underground continuous wall groove segment H shaped steel joint grouting plate of the utility model has following beneficial effect:
(1) with existing employing at the elongated interior subsides plastic foam plate of H shaped steel scope, and fill sand hill or mud drum is compared, the grouting plate 1 that the utility model is arranged on ground-connecting-wall I shape steel plate for sealing water 2 frange plates adopts galvanized sheet iron to make, grouting plate is lightweight, cost is low, construction technology is simple, and prevents streaming effective.
(2) be CN203129188U with patent announcement number, utility model name is called: the anti-by-pass means > of < < underground continuous wall connector > compares, the more reasonable structure of the anti-concrete by-pass means of underground continuous wall groove segment H shaped steel joint grouting plate of the utility model, processing and fabricating, meet construction production order, convenient construction and anti-stream effective:
