Technical Field
The utility model relates to a prefabricated apron fixing device in post-cast strip is applied to industry and civil engineering building basement garage outer wall post-cast strip and carries out peripheral shutoff, waterproof and earthwork in advance and backfills the construction.
Background
In the present stage, large-scale building engineering is increasing day by day, concrete cracks easily appear in an ultra-long reinforced concrete structure due to uneven self shrinkage or uneven settlement, in order to solve common quality problems of concrete structure cracks, a building structure is usually provided with a temperature post-pouring zone and a settlement post-pouring zone, in actual building design, the pouring time of the temperature post-pouring zone is generally not less than 45 days, and the pouring zone needs to be poured after the basement outer wall settlement for 2 months, so that the backfilling speed of a side wall foundation pit is severely restricted, and the construction progress is influenced.
Aiming at the problems, the basement side wall post-cast strip sealing mode in the prior art mostly adopts the prefabricated integral concrete cover plate sealing mode, but the mode is difficult to construct, a large truck, an electric hoist or a winch are used for assisting installation and construction, and the integral installation and fixation operation is inconvenient. Meanwhile, the position of the basement outer wall post-cast strip is poured together with the whole outer wall due to the difference, the sealing performance is low in the actual operation process, the waterproof capability is difficult to test, and the resource utilization of the advanced plugging device is reduced.
Disclosure of Invention
For solving the problem that prior art exists, the utility model provides a prefabricated apron fixing device in post-cast strip, it can firmly with concrete structure wall connection, the leakproofness is strong, has excellent waterproof ability to ensure the steadiness of the prefabricated apron in later stage concrete placement in-process in post-cast strip, and only with a mould can, with low costs and easy operation, transportation and installation are convenient fast, the easy starting of on-the-spot workman's operation.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a post-cast strip prefabricated cover plate fixing device comprises a post-cast strip and a post-cast strip prefabricated cover plate, wherein the post-cast strip prefabricated cover plate is a staggered post-cast strip prefabricated cover plate, bosses and recessed areas which can be used for lapping are arranged at the top end and the bottom end of the staggered post-cast strip prefabricated cover plate, in a lapping state, the bosses at the bottom end of the upper staggered post-cast strip prefabricated cover plate are in staggered lapping with the recessed areas of the lower staggered post-cast strip prefabricated cover plate, and the lapped staggered post-cast strip prefabricated cover plate covers the side end of the post-cast strip; the beneficial effects of this technical scheme lie in: adopt wrong platform formula structure, very big increase sealing effect and waterproof performance, increase the result of use, moreover, the steam generator is simple in structure, the job site only needs two workman can convenient removal and overlap joint, simultaneously, adopt the wrong desk-top concatenation mode of homonymy, when the preparation is lapped in the prefabricated apron factory, only need a template can carry out the apron preparation, very big reduction manufacturing cost, and, application scope is extensive, only need the concatenation can satisfy the not use of co-altitude, and applicable in all post-cast strip that are less than the apron width.
Preferably, horizontal connecting bolts which are leaked out of the wall body are pre-embedded in the wall bodies on the two sides of the post-pouring belt, hollow mounting holes are formed in the longitudinal half positions of the two sides of the staggered post-pouring belt prefabricated cover plate, and the staggered post-pouring belt prefabricated cover plate is fixedly mounted on the wall body through the insertion connection of the hollow mounting holes and the horizontal connecting bolts; the beneficial effects of this technical scheme lie in: the overall safety and the stability are greatly improved, the connection strength between the adjacent cover plates is increased, and the connection is more stable.
Preferably, waterproof parts in 45 degrees are arranged at the end parts of the two sides of the staggered post-cast strip prefabricated cover plate; the beneficial effects of this technical scheme lie in further having increased the water-proof effects of prefabricated apron, increase the water-proof effects of apron both sides and wall body contact position.
Preferably, the waterproof part is waterproof mortar, and the waterproof mortar is filled between the staggered post-cast strip prefabricated cover plate and the wall body; this technical scheme further increases waterproof ability.
Preferably, waterproof mortar is filled at the lap joint between the prefabricated cover plates of the adjacent staggered platform type post-cast strips; the beneficial effects of this technical scheme lie in: the lap joint between the apron is closely knit further to increase waterproof ability through the waterproof mortar shutoff.
