Description
Technical field
The utility model relates to a kind of sole plate prefabricated section ater-casting structure, and is particularly a kind of by reinforced concrete prefabricated sole plate post-poured strip structure that constitutes of T shape sidewall band groove.Belong to building engineering field, be applicable to all kinds of engineerings that sole plate post-poured strip is set.
Background technology
Sole plate post-poured strip is for preventing that monolithic reinforced concrete structure is owing to uneven issuable harmful crack such as sedimentation, temperature, contraction in building operations; According to design or job specfication requirement; Stay in the sole plate relevant position and to establish interim constuction joint; Structure temporarily is divided into several portions, after stipulated time and operation completion, waters again and smash this constuction joint concrete, structure is linked to be integral body.The construction ater-casting water after being divided into the subsiding belt, after water contraction bands and after water the temperature band, be respectively applied for and solve high-rise main building and the sedimentation of low layer podium differences, steel concrete shrinkage strain and reduce problem such as thermal stresses.Position, distance that the ater-casting is set confirm that through designing and calculating its width is considered easy construction, avoided stress to concentrate, and often is 800～1200mm; Position in that waterproof requirement is arranged is provided with the ater-casting, considered waterstop structure.
Because audient's multifactor impact during the actual enforcement in ater-casting; Have that the cleaning of ater-casting place slag inclusion and laitance is clean, problems such as ater-casting raw material quality difference and jointing seepage, ater-casting casting and compacting of concrete leakiness, ater-casting concrete curing difference; The crack that is prone between the New-old concrete also becomes the weak part of structure.Cause the ater-casting construction quality poor, big and be prone to problem such as seepage to duration influence.
Often adopt cast-in-place mode to build simultaneously at present and form the ater-casting, construct, cause being provided with of ater-casting bigger the duration influence owing to need certain curing time just can carry out subsequent handling after the concreting.
In sum, need at present that invention a kind ofly can effectively be shortened the construction period badly, the sole plate prefabricated section ater-casting structure of steady quality, good seepage-proof property.
Summary of the invention
The purpose of the utility model is to adopt cast-in-situ concrete to build to present ater-casting more; Need the long construction intermittent phase; Just can carry out the problem of subsequent handling construction, and adopt cast-in-place mode that the diseases such as waterproof effect difference that the ater-casting is prone to cause are set, it is fast to invent a kind of speed of application; Can significantly practice thrift the construction period, have good water-proof effect, sole plate prefabricated section ater-casting structure that intensity is high simultaneously.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of sole plate prefabricated section ater-casting structure is characterized in that comprising ater-casting prefabricated section and sole plate reservation ater-casting, and prefabricated section cross section, ater-casting is a T shape, and the cross connecting plate of both sides is fixed on the sole plate; Prefabricated section two lateral walls are provided with some grooves in the ater-casting; The inside wall of reserving the ater-casting at sole plate is provided with some prominent pieces; The position of groove and prominent piece, size coupling; Between two adjacent grooves, each prominent piece end is equipped with connecting reinforcement, the ater-casting prefabricated section is installed to sole plate when reserving in the ater-casting, groove and prominent piece are plugged on together.Reinforced concrete prefabricated according to ater-casting length integral body or prefabricate and installation.
Aforesaid sole plate prefabricated section ater-casting structure is characterized in that below sole plate, being provided with ater-casting sealing bed course, and coil waterproof layer is set in the middle of the sealing bed course; Build one deck pointing at sealing bed course top.
Aforesaid sole plate prefabricated section ater-casting structure is characterized in that on the prefabricated section of ater-casting laying the fast hardening concrete leveling layer, and prefabricated section and sole plate cast-in-situ concrete joining place are provided with waterstop in the ater-casting.
Sole plate prefabricated section ater-casting structure when it is characterized in that the ater-casting prefabricated section is installed in the sole plate reservation ater-casting, is reserved space, T shape ater-casting, and the ater-casting prefabricated section is reserved injected hole certainly and poured into pointing after installing; Described pointing is for exempting from the self-compaction expansive concrete that shakes.
