Description
Technical Field
The invention relates to the technical field of building construction, in particular to a structure for closing a post-settlement casting belt in advance.
Background
In recent years, it has been comparatively extensive a marketing means that promotes real estate sales volume to construct basement roof gardens and pipe network in advance as the show area, but in gardens show area work progress, often because the major structure subsides still not stable yet, subsides post-cast strip and can not seal in advance, leads to the gardens show area can not fully demonstrate comprehensively, and the bandwagon effect that produces does not reach the effect that the developer expects, and the mode of handling usually is two kinds generally:
the utility model provides a, the local post-cast strip that directly influences garden construction pours in advance and seals, though garden construction advances to the field in advance, and gardens show area effect reaches anticipated effect, nevertheless major structure subsides and inevitably leads to this position post-cast strip concrete fracture infiltration, and the fracture scope is not limited to post-cast strip position, and the position scope of mending leakage in the future is big, need carry out the concrete leakage many times even and mend, and the antiseep is with high costs, and the corruption influence of a large amount of infiltration of concrete structure to the reinforcing bar is great.
Secondly, lay the steel sheet in post-cast strip position, reserve the waterproofing position after, directly carry out the garden construction after accomplishing the waterproof and protective layer construction of peripheral basement roof, later stage major structure subsides stably the back, excavate again and construct gardens and the pipe network of accomplishing, uncover post-cast strip steel sheet, clear up post-cast strip construction joint back, pour post-cast strip concrete, do water-proofing and protective layer again, will dig out the gardens show area and the pipe network secondary construction of destruction and resume. Although the method avoids water seepage repair of a post-cast strip, the entering excavation of large machinery in the garden display area increases the additional garden site damage and maintenance, earthwork excavation, pipe network and secondary construction cost, and the cost also includes the safe and civilized construction cost in the process.
Therefore, the traditional construction method for closing the post-cast strip in advance cannot meet the modern construction requirements.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a structure for closing a post-settlement casting belt in advance, which can solve the problem that the post-settlement casting belt cannot be closed in time in the traditional garden construction in advance, and also saves a large amount of construction cost for reducing secondary construction of gardens and pipe networks and water seepage repair of a basement roof.
The invention is realized by the following technical scheme:
a structure for closing a settlement post-cast strip in advance comprises I-shaped steel, a post-cast strip concrete beam and post-cast strip concrete; a post-cast strip template supporting system is arranged below the post-cast strip concrete beam; the post-cast strip template support system comprises: the bottom template of the post-cast strip and the bottom template support of the post-cast strip are arranged; the I-shaped steel is pre-buried to the middle of the post-cast strip concrete beam; a post-cast strip concrete slab is arranged above the post-cast strip concrete beam; the post-cast strip concrete is poured into the post-cast strip concrete slab through a steel pipe; a water stop steel plate is arranged in the post-cast strip concrete slab; a steel plate is arranged above the post-cast strip concrete plate; the middle part of the steel plate is connected with the steel pipe; and a waterproof layer is arranged above the steel plate.
Further, the longitudinal spacing of the steel pipes is not more than 4 m.
Furthermore, the steel plate and the steel pipe are in butt welding, and the steel plate and the post-cast strip concrete slab are welded by steel bars.
Further, the I-steel is 18 in size.
Further, the height of the top of the steel pipe is 200mm higher than the elevation of the finished garden surface, and the upper opening of the steel pipe is sealed by an adhesive tape.
Further, the post-cast strip concrete is self-leveling concrete.
The invention has the beneficial effects that:
construction convenience, the installation is simple, and the efficiency of construction is high, adopts high performance self-leveling concrete pouring post-cast strip, guarantees closely knit degree, satisfies standard impervious requirement, reduces the adverse effect that traditional approach closed in advance and subsides post-cast strip and cause, and the construction in gardens show area is accomplished in all-round, also brings very big profit for construction unit marketing development work.
