Abstract
The invention provides a construction method of a space-limited facade structure, which comprises the steps of constructing N-1-N layers of shear walls and N layers of floor slabs, removing a formwork after the concrete grade of the shear walls and the floor slabs meets requirements, prefabricating a formwork in advance according to the actual size requirement on site, placing and fixing a counter-pull screw on the formwork, synchronously constructing the N layers of floor slabs and the N-1-N layers of shear walls when constructing the N-N +1 layers of shear walls, and detaching the outer side formwork of the shear walls, so that the problem that the facade structure cannot be constructed due to limited space in the construction process of the building structure due to the more diversity of buildings is solved. Belongs to the technical field of building construction.
Description
Technical Field
The invention particularly relates to a construction method of a space-limited outer vertical surface structure, and belongs to the technical field of structure construction.
Background
Along with the high-speed development of economy in China, buildings are diversified, the problem that the space of an outer vertical surface structure is limited and construction cannot be carried out exists in the construction process of the building structure, and if a reasonable and safe construction method does not exist, construction cannot be carried out on the site and the construction safety cannot be guaranteed, so that the construction method of the outer vertical surface structure with the limited space is provided.
Disclosure of Invention
The invention aims to provide a construction method of an outer facade structure with limited space, which aims to solve the problem that the outer facade structure cannot be constructed due to limited space in the construction process of the building structure due to the increasing diversity of buildings.
In order to solve the problems, the construction method of the facade structure with limited space is supposed to be adopted, which comprises the following steps:
the method comprises the following steps: firstly, constructing N-1-N layers of first shear walls and N layers of floor slabs;
step two: removing the formwork after the concrete grades of the first shear wall and the floor slab of the N-1-N layers meet the requirements;
step three: prefabricating a template in advance according to the actual size requirement on site, placing and fixing the counter-pulling screw rods on the template, and positioning the template at the construction position of the second shear wall with the N-1-N layers;
step four: when constructing the first shear wall with N-N +1 layers, synchronously constructing floor slabs with N layers and the second shear walls with N-1-N layers;
step five: and removing the templates of the second shear walls of the N-1-N layers.
In the construction method, in order to avoid the die explosion during the in-situ concrete pouring, battens are arranged at the vertical abutted seams of the templates, the battens cover the vertical seams of the templates when the wall templates are assembled, the counter-pull screws are longitudinally and transversely arranged at intervals of 45 cm, and the three rows of counter-pull bolts at the bottommost of the second shear walls of N-1-N layers are reinforced by double nuts.
Compared with the prior art, the invention has the beneficial effects that: the concrete antiskid ridge fixing device is simple and rapid to operate, accurate in size positioning and convenient to fix, can avoid inconvenience and common quality problems in conventional concrete antiskid ridge construction, and is suitable for general popularization.

fig. 2 is a cross-sectional view of a limited facade structure of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings.
Example (b):
referring to fig. 1 and 2, the invention provides a construction method of a space-limited facade structure, which comprises the following steps:
the method comprises the following steps: firstly, constructing N-1-N layers of first shear walls (5) and N layers of floor slabs (4);
step two: removing the formwork after the concrete grades of the first shear wall (5) and the floor slab (4) of the N-1-N layers meet the requirement;
step three: according to the actual size requirement on site, prefabricating a template (2) in advance, placing and fixing a counter-pull screw on the template 2, and positioning the template 2 at the construction position of the second shear wall 1 with N-1-N layers;
step four: when a first shear wall (7) with N-N +1 layers is constructed, a floor slab (6) with N layers and a second shear wall (1) with N-1-N layers are constructed synchronously;
step five: and (3) removing the templates (2) of the second shear walls (1) with the N-1-N layers.
In order to avoid the mold explosion during the in-situ concrete pouring, battens are arranged at the vertical joints of the formworks 2, the battens cover the vertical joints of the formworks 2 when the wall formworks are assembled at each section, the counter-pull screws are longitudinally and transversely arranged one by one at intervals of 45 cm, and the three rows of the lowest counter-pull bolts of the second shear wall (1) with N-1-N layers are reinforced by double nuts.
In order to ensure the safety of site construction: in the concrete pouring process, a specially-assigned person needs to check to find the phenomena of deformation, looseness and the like, and timely reinforcement and repair are needed to prevent people from being injured by a collapsed mold. And (3) dismantling the template according to the guide strength of the test block under the same conditions on site, wherein the template can be dismantled after the template meets the percentage of the design requirement.
The above description is only for the purpose of illustrating particular embodiments of the present invention and is not intended to limit the scope of the present invention. Several simple deductions or substitutions can be made without departing from the concept of the present invention, and should be considered as belonging to the spirit and scope of the technical solution of the present invention.
