Description
Technical Field
The utility model relates to a construction technical field, concretely relates to basement outer wall post-cast strip enclosed construction.
Background
In order to accelerate the construction progress, the outer wall post-pouring belt is temporarily sealed after a formwork on the outer side of the outer wall of the basement is detached on a construction site, and earthwork on the outer side of the outer wall is backfilled in time after the outer wall post-pouring belt is sealed, so that the construction of an upper structure and a floor scaffold foundation is facilitated.
The specific method comprises the following steps: the method comprises the following steps of dismantling a template outside an outer wall, cleaning materials → erecting a post-cast strip closed wall scaffold → constructing a wall with a closed post-cast strip of the outer wall → painting the closed wall with the post-cast strip of the outer wall → curing → constructing a waterproof layer and a protective layer of the outer wall → backfilling and tamping earthwork outside the outer wall, and has the following defects: the construction progress is slow, the process is many, when being used for the multilayer basement construction in factor of safety low, the cost is higher, and when the wall body was built by laying bricks or stones, if quality control is not in place, lead to the wall body to collapse and follow-up seepage condition very easily.
Disclosure of Invention
An object of the utility model is to prior art's defect and not enough, provide a simple structure, reasonable in design, convenient to use's basement outer wall post-cast strip enclosed construction.
In order to achieve the above object, the utility model adopts the following technical scheme: the concrete outer wall comprises a concrete outer wall body, a reinforced concrete precast slab, a lifting ring, outer wall post-cast strip steel bars, cement mortar powder and a waterproof protective layer; the outer side of the concrete outer wall body is provided with a reinforced concrete precast slab, two lifting rings are fixed on the reinforced concrete precast slab, the lifting rings are welded with outer wall post-cast steel bars on the concrete outer wall body, the outer side of the reinforced concrete precast slab is provided with cement mortar powder, and the outer side of the cement mortar powder is provided with a waterproof protective layer.
After the structure is adopted, the utility model discloses the beneficial effect who produces does: a basement outer wall post-cast strip enclosed construction, replace traditional brick method construction, optimized construction process, reduced engineering cost, under the prerequisite of guaranteeing quality and safety, accelerated the construction progress, improved economic benefits, the utility model has the advantages of simple structure, set up reasonable, the cost of manufacture low.

the concrete outer wall body 1, the reinforced concrete precast slab 2, the hoisting ring 3, the outer wall post-cast strip steel bar 4, the cement mortar powder surface 5 and the waterproof protective layer 6.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Referring to fig. 1 to 4, the following technical solutions are adopted in the present embodiment: the concrete outer wall comprises a concrete outer wall body 1, a reinforced concrete precast slab 2, a lifting ring 3, an outer wall post-cast strip steel bar 4, a cement mortar powder surface 5 and a waterproof protective layer 6; the outer side of the concrete outer wall body 1 is provided with a reinforced concrete precast slab 2, two lifting rings 3 are fixed on the reinforced concrete precast slab 2, the lifting rings 3 are welded with outer wall post-cast steel bars 4 on the concrete outer wall body 1, a cement mortar powder surface 5 is arranged on the outer side of the reinforced concrete precast slab 2, and a waterproof protective layer 6 is arranged on the outer side of the cement mortar powder surface 5.
The construction steps of the specific embodiment are as follows:
1. according to the design width of the post-cast strip of the outer wall of 800mm, the excess width of the two sides of the prefabricated slab can adopt the size of 300mm or a little larger according to the difficulty and easiness in installation so as to be convenient for installation and construction, and the thickness can be 60mm (for example, when the height of a multi-layer basement or a basement is larger, the thickness of the prefabricated slab can be also properly increased); the prefabricated slab reinforcement can adopt the deformed steel bar with the diameter of 14 as a main reinforcement and the deformed steel bar with the diameter of 12 as a distribution reinforcement, and simultaneously, two hanging rings are arranged on each prefabricated slab, so that the prefabricated slab can be used for hoisting the prefabricated slab and can also be used for welding with post-cast strip steel bars on an outer wall;
2. after the prefabricated slabs reach 75% of design strength, hoisting can be carried out, each prefabricated slab is hoisted into a working surface which is cleaned in advance by using a tower crane or a truck crane to be installed in place, a welder welds and fixes two hoisting rings on the prefabricated slab and steel bars at the post-cast strip of the outer wall (the hoisting ring steel bars and the steel bars at the post-cast strip of the outer wall can be welded and connected by adopting short steel bars), and after the installation position and the welding quality are checked to be correct, a second block and a third block can be hoisted according to the method until the installation of the prefabricated slabs is finished;
3. the prefabricated plate installation can carry out the construction of whitewashing layer of board seam and face after accomplishing, need carry out the interface to the face and handle before whitewashing, whitewashes and adopts 1: 2, leveling the cement mortar to be used as a waterproof base layer surface, and controlling the plastering thickness to be about 20 mm. And carrying out conventional maintenance after the painting is finished, and carrying out construction of a waterproof and protective layer and a subsequent procedure after the maintenance.
Before the construction of the concrete embodiment, the number of the prefabricated slabs is calculated according to the requirement of a design drawing on the width of the post-cast strip of the outer wall of the basement, the length, the width and the thickness of the prefabricated slabs are determined, parameters such as reinforcing bars, concrete marks and the like of the prefabricated slabs are determined, the prefabricated slabs made of the reinforced concrete are prepared in advance for later use after the information is determined, and the installation of the prefabricated slabs is completed after the construction conditions and the strength of the prefabricated slabs reach a certain strength level, so that the traditional construction process of brick wall masonry painting is replaced.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
