Description

A kind of sole plate post-poured strip steel plate for sealing water combining structure
Technical field
The utility model relates to a kind of device that the bigger concrete structure of underground area prevents position, ater-casting percolating water that is used for, and in particular, the utility model relates to a kind of sole plate post-poured strip steel plate for sealing water combining structure.
Background technology
At present, in industry and civilian construction were constructed, the Foundation Design that area is bigger all will be kept somewhere the ater-casting.The ater-casting is for preventing that monolithic reinforced concrete structure is owing to the interim constuction joint of establishing is stayed according to the code requirement that designs or construct in harmful crack that reasons such as temperature, contraction inequality and differential settlement produce in sole plate, wall, beam relevant position in building operations; This constuction joint temporarily is divided into several portions with structure; After the process contraction process of component inside some time; Again to this constuction joint disturbing concrete, thereby the several portions of structure is linked to be an integral body.
But, the construction of such ater-casting, often the situation of percolating water appears in the bonding surface at position, basic ater-casting, and both administers very difficulty, is not easy again to administer thoroughly.
For this reason, the insider has studied and multiplely the method for percolating water situation occurred in order to prevent and treat position, aforementioned basic ater-casting bonding surface, for example the expansion sealing rod that adopts of prior art, rubber fastening band, leading sealing ater-casting, steel plate for sealing water or the like.Yet all there are shortcomings and deficiencies in various degree in the employing of these methods:
(1) adopt the expansion sealing rod, generally speaking, the antiseep effect is not too obvious;
(2) adopt rubber fastening band,, be easy to during construction also not have the sealing effect owing to reasons such as stone, iron wire and vibratory concrete are destroyed because of its intensity is lower;
(3) adopt leading sealing ater-casting, though certain effect is arranged, its cost is very high, and effect neither be very remarkable;
(4) adopt steel plate for sealing water; Though effect is more obvious,, in work progress, cause steel plate for sealing water off normal phenomenon and foreign material to fall into the situation in the ater-casting easily because of the concrete in the ater-casting is excessive owing to be difficult to fix; Thereby directly influence stagnant water effect, cause the fund waste.
The utility model content
The utility model technical problem to be solved just provides the sole plate post-poured strip steel plate for sealing water combining structure that a kind of steel plate for sealing water off normal that causes because of concrete is excessive when having good antiseep effect, can play the sealing effect reliably and preventing concreting and foreign material fall into phenomenon in the ater-casting.
The technical purpose of the utility model is achieved through following technical scheme:
A kind of sole plate post-poured strip steel plate for sealing water combining structure comprises steel plate for sealing water, and the upper and lower part of said steel plate for sealing water is provided with the upper and lower steel fabric sheet that is positioned at its longitudinal center respectively; The described steel fabric sheet of going up is by some upright upper support reinforced bar support, and some described upper support reinforcing bars are fixed with the second main muscle that is connected its lower end through the first main muscle that connects in the top respectively; Described steel fabric sheet down is by some upright lower support reinforced bar support, and some described lower support reinforcing bars are fixed with the 4th main muscle that is connected its lower end through the 3rd main muscle that connects in the top respectively; Said upper and lower steel fabric sheet is welded as a whole through the second main muscle and the 3rd main muscle and described steel plate for sealing water respectively, and the both sides, below of said steel plate for sealing water are the welded reinforcement support respectively.
Adjacent two described upper support bar space are not more than 300mm.
Adjacent two described lower support bar space are not more than 300mm.
The spacing of adjacent two said Steel bar racks is not more than 500mm.
The utility model compared with prior art has following beneficial effect:
(1) because the steel plate for sealing water in the utility model and the main muscle of steel fabric sheet are welded as integral body; So possessed good fixed effect; Thereby the steel plate for sealing water in work progress of avoiding common appearance in the prior art is placed and fixing difficult and phenomenon easy off normal in concreting process, and stagnant water effect is remarkable.
(2) because being welded as on whole and the described upper and lower steel fabric sheet, upper and lower steel fabric sheet in the utility model and described steel plate for sealing water be provided with some bearing bars; So be convenient to firm fixation; Thereby effectively prevent concrete leaking outside in the process of building; And guarantee that described upper and lower steel fabric sheet can not destroyed because of pressure too big in the work progress, has avoided the defective that concrete leaks outside in the prior art.
(3) since in the utility model with the main muscle of said upper and lower steel fabric sheet upper/lower terminal main body fixing ribs as said upper and lower base plate, so practiced thrift reinforcing bar to a certain extent, reduced cost.
(4) since in the utility model with the cushion block of described mortar bar as the lower shoe reinforcing bar, not only can save the operation that cushion block is set specially but also the concrete can guarantee to build the time can not leak outside because of the slit between reinforcing bar and the bed course, thereby guarantee workmanship.
(5) because when installing the combining structure of the utility model; The concrete grout that is provided with wide 400mm at the place, ater-casting accumulates groove and is used for storing a small amount of concrete grout that outflows in the mesh by said upper and lower steel fabric sheet; So can avoid the cleaning work that cuts in later stage, thereby improve speed of application.
(6) because the composite board combining structure that upper plate top is fixed corresponding to the zone of said ater-casting described in the utility model is a block mold; And, fixes underplate concrete before building; Remove when treating ater-casting concreting; So guaranteed the neat, straight of edge, ater-casting, foreign material and the rubbish also having avoided simultaneously occurring usually in the prior art fall into the situation in the ater-casting, thereby reduce because the manpower that cleaning work caused and the waste of time of later stage foreign material.
