Abstract
The utility model relates to an expansion joint drain structure of a fixed building, which comprises a groove (1), an expansion joint (8) positioned at the bottom of the groove (1), and a groove cover board (11). The expansion joint drain structure is characterized in that a drain trench (9) is arranged tightly close to the expansion joint (8); a polyline-shaped cover flashing (4) spans the expansion joint (8), a lower end (6) of the polyline-shaped cover flashing (4) is fixed in the section between the expansion joint (8) and the drain trench (9), and an upper end (5) is movably connected with the upper end of aside wall (3) of the groove at the other side of the expansion joint; the bottom level of the drain trench (9) is lower than that of the cover flashing, and the cover flashing (4) discharges a slope towards the drain trench. The drain structure overcomes the defect of the unstable performance of the existing expansion joint drain structure, meanwhile, overcomes the defect of limited adoption of the single solid sealing cover board.
Description
Technical field
The utility model belongs to a kind of drain structure of fixed buildings, especially at building roofing or ground drain structure when crossing over the shrinkage joint is set.
Background technology
Because of satisfying requirements such as earthquake resistant engineering, the temperature difference or sedimentation, the shrinkage joint need be set on building, the shrinkage joint exposes outside the building, exposes roofing, ground etc. such as the shrinkage joint, just needs to consider its waterproof.Present drain structure is: at roofing or underground groove is set, the shrinkage joint is imbedded and is fixed in the groove, at the top of groove one seal cover board is set.As shown in Figure 1.
But, have following problem: general sealing effectiveness is because of reasons such as construction or long-term uses, can't guarantee that water is isolated in outside the groove fully, produce ponding at bottom portion of groove easily, though the shrinkage joint generally all is provided with waterstop, but easily the waterproof at shrinkage joint is constituted influence, thereby influence the workmanship of whole building.In addition, the architect as takes all factors into consideration other architectural factors when architectural design, when cover plate need be with blank form, just can't satisfy its practicality.
Summary of the invention
In order to overcome existing water discharge structure of expansion joint unstable properties, cause the drawback of ponding in the groove easily, simultaneously, can only be single solid airtight cover plate also in order to overcome the cover plate form, the utility model provides a kind of can effectively solve the shrinkage joint surface drainage, and can use various cover plate forms, satisfy the drain structure of various architectural coating requirements.
In order to solve the problems of the technologies described above, the technical scheme of being taked is:
A kind of water discharge structure of expansion joint comprises groove, is positioned at the shrinkage joint and the groove cover plate of this bottom portion of groove, and a gutter is close to described shrinkage joint and is provided with; One broken line shape apron flashing is crossed over described shrinkage joint and is provided with, and the lower end is fixed between described shrinkage joint and this gutter in the section, and the upper end is movably connected on the recess sidewall of shrinkage joint opposite side; The end absolute altitude of described water row ditch is lower than the end absolute altitude of described apron flashing lower end, and apron flashing is put the slope to the gutter.
As preferred version, described apron flashing lower end directly is fixed on the waterstop embedded part at described shrinkage joint.The apron flashing lower end can be fixed on the elongation end of described waterstop embedded part with bolt and packing ring.
Described recess sidewall is close in the apron flashing upper end, the peripheral hardware buckle, and this buckle and apron flashing upper end overlap joint, lap-joint can play glue or not play glue.Also can adopt the apron flashing upper end to be linked to be integral body with buckle, the junction becomes N shape.
At above-mentioned arbitrary technical scheme, described cover plate can be blank form.
Utilize above-mentioned shrinkage joint, ditch and an end to fix, the apron flashing that the other end flexibly connects, can guarantee the waterproof at shrinkage joint, simultaneously, can connect the drainage of shrinkage joint draining and building itself, right when satisfying the architect whole building being designed, deal carefully with the appear node processing at place of shrinkage joint, use multi-form cover plate, finish the effect of building surface Total tune.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples and application construction method.
Fig. 1 is the structural section between existing shrinkage joint, groove and the cover plate.
Fig. 2 is a sectional drawing of the present utility model.
Fig. 3 is that apron flashing is connected detail drawing with the N shape integral body of buckle.
The specific embodiment
As shown in Figure 2, shrinkage joint 8 is embedded in the groove 1, appears to hold and be provided with waterstop in the shrinkage joint, and a broken line shape apron flashing 4 is on this shrinkage joint.This apron flashing can adopt down Z-shaped or other broken line shapes, the lower end 6 of apron flashing can be fixed on the concrete between shrinkage joint and the ditch, connected mode can be preset embedded part in concrete, connect with bolt, pad, also can fix with other modes such as welding, riveted joints.The method of recommending is the built-in fitting 7 that utilizes the shrinkage joint waterstop itself to have, and only needs the exposed junction of embedded part is prolonged, and with bolt 10,12 and pad 13,14 apron flashing lower end 6 is fixed on the elongation end 2 of this waterstop built-in fitting 7 then.Like this, can save material, use embedded part less, save construction costs, easy construction simultaneously, succinct.
Owing to the setting at shrinkage joint is that so an end of apron flashing is fixed, the other end must flexibly connect for the relative changing of the relative positions of offsetting the building each several part is provided with, could cooperate shrinkage joint work.The upper end 5 of apron flashing 4 is movably connected on the opposite side sidewall 3 of groove, can along laterally, vertically and the plane move outward, with the work of cooperation shrinkage joint, be unlikely in building vibrations, sedimentation or broken or twist off when having temperature deformation.The flexible connection of adopting is: described recess sidewall 3 is close in apron flashing upper end 5, peripheral hardware buckle 15, and this buckle 15 and apron flashing upper end 5 overlap joints, lap-joint can play glue or not play glue.Buckle can be angle steel shape, and an end is fixed on the horizontal plane, and the other end is encorbelmented sagging, covers the upper end of broken line plate.
The flexible connection of apron flashing upper end 5 also can be linked to be integral body with buckle with the apron flashing upper end except said method, the junction becomes N shape 16, as shown in Figure 3.
In order to guarantee that Water seeks its own level, must guarantee that apron flashing puts the slope to the ditch, and the bottom surface absolute altitude in ditch is lower than the end absolute altitude of apron flashing lower end 6.
The length of apron flashing can be reduced like this because of being provided with near the shrinkage joint in the ditch, and is more economical, reasonable, and the drainage line of current is shortened.This ditch can utilize rain rill or other gutters that itself just has in the building, is linked to be integral body with the drainage system of building, and does not need to consider how water is discharged outside the building in addition.
Be provided with cover plate 11 at the top of groove 1, this cover plate can be blank or solid, the ponding not because water can arbitrarily flow into groove 1 bottom, so the form of cover plate can arbitrarily be provided with, and maintenance and cleaning all make things convenient for.Owing to do not need to consider sealing, installation difficulty is reduced greatly, under the prerequisite of ensuring the quality of products, accelerate speed of application simultaneously.
