The specific embodiment
The invention provides a kind of job practices of single side formwork system, operation is simple, has improved work efficiency, and the exterior wall Surface Quality of Concrete of building is good, does not have the mould of expanding, runs the mould phenomenon, and applicability is stronger.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, complete description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.
The job practices of a kind of single side formwork system that the embodiment of the invention provides, this formwork system comprise embedded part system, wall form and one-sided support, it is characterized in that, comprising:
Step 1: confirm an end that ground place and pre-embedded anchoring bolts of the stone bolt of embedded part system according to the position of neighboring walls, the other end elevates above the soil and becomes 45 angles spent with ground.
On-the-spot stone bolt requires to draw logical line when pre-buried, guarantees it on same straight line, and each pre-embedded anchoring bolts spacing is 300mm, should respectively arrange a stone bolt at the Origin And Destination place near one section body of wall.
Step 2: select wall form; With wall form with the mode parallel with neighboring walls; Be assembled in the said neighboring walls of distance a distance, adopt the weather strip sealing between the limit seam of wall form and wall form side and wall form end opening and the construction ground.
For preventing spillage, the seam of wall form and wall form side adopts the sponge strip sealing of band double faced adhesive tape, and wall form end opening use cross section is 50 * 20 sponge strip joint filling.
Step 3: set up the one-sided support of triangle; The one-sided support of triangle comprises that the right-angled trapezium that is installed in the lower end increases joint; With the triangle standard knot that is positioned at the upper end; At the position, right angle that right-angled trapezium is increased joint two ends tilt to be installed and to be separately fixed at the steel pipe on the right angle portion both sides, and with linkage with in the steel pipe of one-sided support and the embedded part system with stone bolt on the connecting rod that is connected fix.
The support body part of one-sided support can be processed into differing heights, and according to highly being divided into three kinds of specifications: H=3600 standard knot, H=500 increase joint, H=1600 increases joint and H=3200 increases joint.One-sided support should be put down light rising gently when lifting, many Pin support is deposited in a time-out, should stack each other on the ground neatly at smooth, in order to avoid deformation of timbering.
Step 4: wall form partly is connected with the montant of one-sided support with linkage.
The montant of one-sided support is partly fixed with gib headed bolt and wall form fastener and wall form.
Step 5: the nuts and bolt of the rear support of the one-sided support of up-down adjustment lower end makes wall form summary suitable for reading to tilting within the walls.
Behind the one-sided support force, wall form is with slightly retreating, and it is suitable for reading to the 5mm that inclines approximately within the walls therefore to regulate wall form.
Step 6: concreting between the body of wall of wall form and adjacent building.
Fastening and inspection embedded part system and wall form, the template end opening can spillage when guaranteeing concreting, concreting, wall thickness 500mm.
Step 7: after concrete wall reaches form removal intensity, earlier loosening one-sided support rear support, disconnection one-sided support in back is connected with stone bolt, takes off one-sided support.
Establish the difficult problem of construction that the external wall construction scope of operation causes because of staying on request when implementation method of the present invention efficiently solves the underground garage excavation, and adopted corresponding construction technology to the different situations of circular arc place body of wall and stalk section.Because of adopting the single side formwork method to save a large amount of raw material, and dwindle the construction plant area, for placing of material with face to build etc. advantage is provided, improved work efficiency.
Although embodiment of the present invention are open as above; But it is not restricted to listed utilization in manual and the embodiment; It can be applied to various suitable the field of the invention fully, for being familiar with those skilled in the art, can easily realize other modification; Therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the present invention is not limited to specific details and illustrates here and describe.
