Description
Technical field
The utility model relates to a kind of reinforced concrete construction techniques, disclose a kind of for hydraulic engineering structures bottom plate
T-type post-cast strip stay seam pattern.
Background technique
With the continuous development of engineering design technology, the construction of all kinds of engineering structures is showed to be developed to large scale
Trend.For reinforcing bar soil material as modern most common construction material, crack problem is its relatively conventional defect.Post-cast strip
It is in order to adapt to the factors such as variation of ambient temperature, concrete shrinkage, structure differential settlement and influence, in beam, plate (including basic bottom
Plate), reserve in the structures such as wall with one fixed width and the concrete belt by pouring again after a certain period of time, be widely used in work
Cheng Shiji.The construction technology of post-cast strip is taken, building structure can be effectively improved because above-mentioned reason generates asking for structural crack
Topic, improves structural integrity, and with pour in the related specifications and not yet explicitly pattern and seepage control measure of two sides preset slot.After tradition
It pours and stays seam pattern frequently with straight seam or the pattern of key joint with two sides, the cold seam of construction easy to form, anti-seepage effect is not good enough.Phase
It is smaller compared with the work China Democratic National Construction Association universal size of field underground structure, and hydraulic engineering structures soak for a long time and the biggish spy of structure size
Point can stay seam pattern by improvement post-cast strip, concrete self-characteristic is made full use of to enhance post-cast strip anti-seepage effect.
Utility model content
The purpose of the utility model is to provide a kind of T-type post-cast strips for hydraulic engineering structures bottom plate to stay seam pattern,
Using itself impervious characteristic of heavy-gauge steel reinforced concrete, that improves post-cast strip stays seam pattern to enhance its anti-seepage effect.
To achieve the goals above, the technical solution of the utility model is as follows: one kind being used for hydraulic engineering structures bottom plate
T-type post-cast strip stay seam pattern, hydraulic engineering structures bottom plate is by the bottom plate elder generation pouring concrete being set on bed course and post-cast strip
It constitutes, it is characterised in that the bottom plate elder generation pouring concrete of post-cast strip two sides is stepped, forms T-type between bottom plate elder generation pouring concrete
Seam is stayed in post-cast strip, and T-type post-cast strip stays in seam casting concrete to form T-type post-cast strip, the top girth of T-type post-cast strip with first pour it is mixed
Solidifying soil junction is equipped with hydro-expansive rubber item, and the top girth underside plan of T-type post-cast strip forms slip casting and repairs face.
Further, the first pouring concrete that the setting of the two sides T-type post-cast strip Liu Feng stays seam to match with T-type post-cast strip is ladder-like
Template, and fixed in the T-type post-cast strip two sides Liu Feng dense mesh or fast-easy closing-up net closing.
Further, at compressive sealed dose of faying face brushing of bottom plate elder generation pouring concrete and T-type post-cast strip.
Further, waterproof roll envelope is laid in bottom plate elder generation pouring concrete and post-cast strip junction between bottom base plate and bed course
Stifled seepage flow entrance.
This kind of post-cast strip stays seam pattern boundary smooth, constructs convenient for formwork erection, while increased flange portions extend seepage flow
Path.Underground water can form one layer of fine and close waterproof with compressive sealed dose of generation hydration reaction in gap in flow event
Adhesive layer.Uncompacted problem of vibrating when concreting can be further compensated for after the pressurized slip casting in repairing face on the downside of the edge of a wing.
Compared with prior art measure, utility model has the advantages that
1. the feature for combining thick base plate size big, makes full use of the impervious characteristic of armored concrete itself
2. slip casting repairing face can be used for filling, repair gap, without embedded steel plate for sealing water
3. shape is simple, it is convenient for formwork erection, improves construction efficiency.
Detailed description of the invention
Fig. 1 is the schematic structural cross-sectional view of the utility model.
It include bottom plate elder generation pouring concrete 1, T-type post-cast strip 2, hydro-expansive rubber item 3, slip casting repairing face 4, close mesh steel in figure
Silk screen or fast-easy closing-up net 5, compressive sealed dose 6, bed course 7, waterproof roll 8.
Specific embodiment
Referring to attached drawing 1, the utility model is described in further detail:
As shown, seam pattern is stayed in a kind of T-type post-cast strip for hydraulic engineering structures bottom plate, the bottom plate is by being arranged
In on bed course bottom plate elder generation pouring concrete 1 and T-type post-cast strip 2 constitute, reinforcing bar perforation is constantly, special in bottom plate at T-type post-cast strip
It is ladder-like that sign is that the bottom plate elder generation pouring concrete 1 of post-cast strip two sides is formed, after forming T-type between the bottom plate elder generation pouring concrete of two sides
Pour band and stay seam, T-type post-cast strip stays in seam casting concrete to form T-type post-cast strip 2, the top girth of T-type post-cast strip with first pour it is mixed
Hydro-expansive rubber item 3 is equipped at solidifying soil occlusion, the top girth underside plan of T-type post-cast strip forms slip casting and repairs face 4.
Specifically, waterproof roll 8 is laid on 7 surface of bed course at the setting of post-cast strip in advance, and coagulation is first poured in post-cast strip two sides
Soil is ladder-like at being mutually engaged with T-type post-cast strip according to specific structure size formwork erection, and with dense mesh or fast-easy closing-up net 5
Two sides are closed and are fixed, prevent first pouring concrete from trickling to post-cast strip bottom.Reach post-cast strip indwelling time and to pouring base
After being disposed, compressive sealed dose 6 is brushed in conjunction old and new concret face and buries patch hydro-expansive rubber 3, is designed using than original
The concreting that the micro-expansion cement of a high grade is prepared is closely knit, reinforces maintenance.Later period, can be by repairing if any leakage to slip casting
The mode of 4 grouting under pressure of benefit face fills gap.
Wherein the width of post-cast strip bottom is B, and the extension elongation of post-cast strip top girth is 0.6 ~ 0.7B, and the height of bottom plate is
H, the height of post-cast strip top girth are 0.35 ~ 0.45H.
Undeclared part involved in the utility model is identical as existing design, construction technology.
