Abstract
The utility model discloses the also crack structure of a kind of mass concrete construction seam, comprise constuction joint and be placed in the Ω template above constuction joint, reinforcing bar is provided with above described Ω template, reinforcing bar is indulged lateral arrangement and is formed steel mesh reinforcement, the interior also pre-buried pvc pipe of described Ω template, and pvc pipe is drawn outside concrete.The utility model utilizes Ω template, top or periphery concrete and concrete construction form a cavity between stitching, the space making concrete construction joint continue to develop is isolated, and then inside concrete stress is effectively discharged, after seam development stability to be onstructed, by pvc pipe grouting filling Ω template and concrete construction stitch between cavity and constuction joint, and vertical lateral arrangement reinforcing bar forms steel mesh reinforcement on Ω template, prevent constuction joint from further developing, thus reach that mass concrete construction is stitched and stitch process, effective prevention constuction joint continues development, ensure structural safety and normal use.
Description
Technical field
The utility model relates to mass concrete construction seam processing technology field, particularly relates to the also crack structure of a kind of mass concrete construction seam.
Background technology
As everyone knows, large volume concrete structural size and concrete square amount are comparatively large, in work progress, often need because constructing the constuction joint arranging some necessity, if limit concrete construction joint development not in time, will affect structural safety and normal use.Conventional concrete construction joint to stitch treatment measures be utilize reinforcing bar tensile characteristics, by laying carrying out of multistory reinforced net restriction constuction joint, shown by monitored data, this kind mode of stitching is sewed with comparatively positive effect for the construction that stress is less, but for the constuction joint of stress larger portion position, the restriction effect that steel mesh reinforcement develops constuction joint is limited, and therefore how preventing concrete in mass interior construction from stitching and continue development, is current concrete construction joint processing technology field problem demanding prompt solution.
Utility model content
For solving the problem, the also crack structure that the utility model provides a kind of mass concrete construction to stitch, stitches to prevent concrete in mass interior construction and continues development.
The utility model is achieved by following technical solution.
A kind of also crack structure of mass concrete construction seam, comprise constuction joint and be placed in the Ω template above constuction joint, be provided with reinforcing bar above described Ω template, reinforcing bar is indulged lateral arrangement and is formed steel mesh reinforcement, the interior also pre-buried pvc pipe of described Ω template, and pvc pipe is drawn outside concrete.
Described Ω template adopts steel plate to be processed into.
Described pvc pipe is divided into two semi-circular shape inside configuration being placed in Ω template.
At above-mentioned concrete construction joint and in crack structure form, steel plate is adopted to be processed into Ω template, ensure that tube wall has certain thickness, before top or periphery concreting, Ω template is placed on concrete construction joint, on Ω template, vertical lateral arrangement reinforcing bar forms steel mesh reinforcement, it is inner that pvc pipe is embedded in Ω template in advance, and draw outside concrete.Then concrete continues to build, and it is closely knit that the later stage carries out grout filling by pvc pipe to Ω template and constuction joint.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by utilizing Ω template, top or periphery concrete and concrete construction form a cavity between stitching, the space making concrete construction joint continue to develop is isolated, and then inside concrete stress is effectively discharged, after seam development stability to be onstructed, by pvc pipe grouting filling Ω template and concrete construction stitch between cavity and constuction joint, and vertical lateral arrangement reinforcing bar forms steel mesh reinforcement on Ω template, prevent constuction joint from further developing, thus reach that mass concrete construction is stitched and stitch process, effective prevention constuction joint continues development, ensure structural safety and normal use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-Ω template, 2-PVC manages, and 3-reinforcing bar, 4-concrete construction joint, 5-concrete construction joint also stitches aspect.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, the also crack structure of a kind of mass concrete construction seam described in the utility model, comprise constuction joint 4 and be placed in the Ω template 1 above constuction joint 4, reinforcing bar 3 is provided with above described Ω template 1, reinforcing bar 3 is indulged lateral arrangement and is formed steel mesh reinforcement, the interior also pre-buried pvc pipe 2 of described Ω template 1, and pvc pipe 2 is drawn outside concrete.Then concrete continues to build, and it is closely knit that the later stage carries out grouting filling by pvc pipe 2 pairs of Ω templates 1 and constuction joint 4.
Adopt this technical scheme when constructing, before stitching aspect 5 top concreting, Ω template 1 is placed on constuction joint 4 at concrete construction joint, on Ω template 1, vertical lateral arrangement reinforcing bar 3 forms steel mesh reinforcement again, pre-buried pvc pipe 2 in Ω template 1, pvc pipe 2 is drawn outside concrete, it is closely knit that later stage carries out grout filling by pvc pipe 2 pairs of Ω templates 1, thus reach and stitch effect.
Described Ω template 1 adopts steel plate to be processed into.Draw materials conveniently, construction cost is low, when processing and fabricating, ensures that steel plate has certain thickness.
Described pvc pipe 2 is divided into two semi-circular shape inside configuration being placed in Ω template 1.And draw outside concrete, wherein to hold concurrently return pipe as stack for one, another root is as grout pipe.
