Abstract
The invention discloses a construction method for preventing a guide wall from sputtering laitance, and belongs to the technical field of building construction. The method comprises the following steps: the method comprises the following steps: after a concrete construction joint is formed, a double-faced adhesive tape is pasted along the edge of the construction joint before formwork erection; step two: sticking a layer of plastic thin paper on the double-faced adhesive tape to enable the screw on the lower guide wall to penetrate through the plastic thin paper; step three: when a formwork is erected, the formwork deviates 250-300 mm towards the lower guide wall and is continuously reinforced by using a screw of the lower guide wall; step four: and after the concrete pouring is finished, taking down the plastic thin paper. According to the invention, the double faced adhesive tape is pasted on the edge of the concrete construction joint, and the plastic thin paper layer is pasted on the double faced adhesive tape, so that the plastic thin paper can be vertically downward to support the formwork, and the laitance can be splashed onto the plastic thin paper when the concrete is poured.
Description
Technical Field
The invention relates to the technical field of building construction, in particular to a construction method for preventing a guide wall from sputtering laitance.
Background
The floating slurry is a layer of slurry floating on the surface of concrete after the concrete is cast and molded, generally, particles deposited on the surface along with water secretion in the concrete with large water cement and poor working performance consist of hydrated and condensed cement and fine particles in sand, contain a large amount of water, and a porous loose layer is left after the water is evaporated. The surface of the concrete is easy to cause sand and crack, the strength and the impermeability of the concrete are affected, when the concrete needs to be continuously poured or jointed, the concrete needs to be removed to strengthen the adhesion between the newly poured concrete and the previously poured concrete, and the lower guide wall needs to avoid slurry leakage and slurry sputtering so as not to affect the engineering quality.
Disclosure of Invention
1. Technical problem to be solved by the invention
The construction method can effectively avoid the laitance generated by pouring the concrete while not influencing the attaching degree of the template and reduce the labor cost generated by later cleaning.
2. Technical scheme
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
the invention relates to a construction method for preventing a guide wall from sputtering floating slurry, which comprises the following steps:
the method comprises the following steps: after a concrete construction joint is formed, a double-faced adhesive tape is pasted along the edge of the construction joint before formwork erection;
step two: sticking a layer of plastic thin paper on the double-faced adhesive tape to enable the screw on the lower guide wall to penetrate through the plastic thin paper;
step three: when a formwork is erected, the formwork deviates 250-300 mm towards the lower guide wall and is continuously reinforced by using a screw of the lower guide wall;
step four: and after the concrete pouring is finished, taking down the plastic thin paper.
3. Advantageous effects
Compared with the prior art, the technical scheme provided by the invention has the following beneficial effects:
according to the invention, the double faced adhesive tape is pasted on the edge of the concrete construction joint, and the plastic thin paper layer is pasted on the double faced adhesive tape, so that the plastic thin paper can be vertically downward to support the formwork, and the laitance can be splashed onto the plastic thin paper when the concrete is poured.

Detailed Description
The invention is further described with reference to the following figures and examples:
example 1
As can be seen from fig. 1-2, the construction method for preventing the guide wall from sputtering floating slurry of the embodiment includes the steps of:
the method comprises the following steps: as can be seen from fig. 1-2, the position a in the figure is the installation position of the double faced adhesive tape, after the concrete construction joint is formed, the double faced adhesive tape is pasted along the edge of the construction joint before the formwork is erected;
step two: 3-4, the position B is the plastic tissue installation position, and a layer of plastic tissue is adhered to the double-faced adhesive tape, so that the screw on the lower guide wall passes through the plastic tissue;
step three: as can be seen from fig. 5-7, the position C in the figure is the screw installation position, and when the formwork is supported, the formwork deviates 250 mm-300 mm from the lower guide wall and is continuously reinforced by using the screws of the lower guide wall;
step four: and after the concrete pouring is finished, taking down the plastic thin paper.
The concrete construction joints are kept at positions where the structure is less stressed and convenient to construct, and when the horizontal construction joints are arranged in layers, the positions and the interval time of the horizontal construction joints are determined according to the temperature crack control requirement in the concrete pouring process, the concrete supply capacity, the construction of the steel bar engineering, the installation of embedded pipes and other factors except that the horizontal construction joints meet the design requirement.
According to the invention, the double faced adhesive tape is pasted on the edge of the concrete construction joint, and the plastic thin paper layer is pasted on the double faced adhesive tape, so that the plastic thin paper can be vertically downward to support the formwork, and the laitance can be splashed onto the plastic thin paper when the concrete is poured.
The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the invention, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the invention.
