Description
Technical field
The invention belongs to the realm of building construction, relate to a kind of decoration exposed concrete construction method split bolt punch die used.
Background technology
At present, existing decoration clear-water concrete structure exist that reinforcing bar binding is of poor quality, concrete pouring quality is poor, the problem of wall body decoration weak effect, cannot meet customer requirement, therefore need to improve.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides the decoration exposed concrete construction method split bolt punch die used that a kind of reinforcing bar binding quality is high, concrete pouring quality good, wall body decoration is effective.
The present invention is achieved through the following technical solutions:
Decoration exposed concrete construction method of the present invention split bolt punch die used, it is characterized in that: comprise a cylinder, the round platform of protrusion is had outside cylinder upper end, cylinder lower end outside has external screw thread, round platform axis cross section is trapezoidal, and round platform upper end diameter is little, and lower end diameter is large, on the external screw thread of cylinder lower end, cover has nut, barrel bore 1.5cm; This split bolt punch die lower end is inserted in the hole template from template front, and the external screw thread that nut is enclosed within cylinder from template back surface is tightened fixing; After building, form the tubaeform split bolt hole that mouth diameters is large, base diameter is little.This mould adopts steel mould.
The invention has the beneficial effects as follows, reinforcing bar binding quality can be ensured, can concrete pouring quality be improved, wall body decoration effect can be improved, obtain economic and social benefit preferably.Decoration dry concrete construction principle adopts steel frame pipe to install in the assembling reinforcement stage; When one step is built, template adopts punching block version; Steel mould is installed in template upper bolt hole position.Installing by steel frame pipe, effectively ensure that straight cis degree and the verticality of reinforcing bar, improve reinforcing bar binding quality, protective layer thickness can meet the demands.The use of one step body of wall steel form, ensure that the directly suitable of constuction joint, stops secondary and builds bad root phenomenon generation, solve the problem that voids and pits is more.Concreting completes, and after bolt hole steel mould is removed, hole percentage of head rice is high, smoother attractive in appearance.Built-in fitting is fixed on wall form, builds rear guarantee built-in fitting and body of wall in same plane.Save maintenance cost, obtain good economic benefit and social benefit.The method is applicable to big-and-middle-sized decoration clear-water concrete structure.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.Fig. 2 is split bolt punch die schematic diagram.
In figure, 1 cylinder, 2 round platforms, 3 external screw threads, 4 nuts, 5 templates, 6 endoporus.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.
Decoration exposed concrete construction method of the present invention, comprises the following steps: base plate steel bar binding → brushing release agent, base plate model sheetinstallat and reinforcing → underplate concrete are built, → wall steel bar colligation → split bolt punch die installation of fully vibrating in time, installation of embedded parts, top board and wall form are installed and reinforcing → top board and walls concrete is built, fully vibrate in time → stripping → maintenance → beautify bolt hole.
Decoration dry concrete construction principle adopts steel frame pipe to install in the assembling reinforcement stage; When one step is built, template adopts punching block version; Steel mould is installed in template upper bolt hole position.
Before base plate steel bar binding step, also comprise preparation of construction step, namely carry out surveying setting-out to scene, channel excavation completes, and carries out bed course and builds, and in casting process, hanging wire controls its planeness, prevents from impacting lower step operation.
In wall steel bar step of ligation, be Control protection layer thickness uniformity, after wall steel bar, set up scaffold, wall steel bar is erected muscle colligation on scaffold, controls the straight cis degree of reinforcing bar and verticality, in reinforcing bar binding process, control spacing well, want colligation firm, position colligation is accurate; The assembling reinforcement stage adopts steel frame pipe to install.
After wall steel bar colligation completes, start to install a step wall form, in order to reach cicada seam effect, its edge joint position pastes one sponge adhesive tape in template; Install formwork reinforcement screw in process will screw, ensure that the straight genial piece of template is tight; Template adopts steel form.
When underplate concrete is built, the Angle Position of smearing in template drills through an air-vent every 50cm, for discharging the bubble produced in casting process, to reach impression quality.
Before two step wall forms are installed, template is installed split bolt punch die, and eyelet cross direction profiles spacing is 60cm, fore-and-aft distance 50cm, ensures that cicada seam is on the center line between bolt.
During installation of embedded parts, body of wall light current built-in fitting is elongated, when in processing, just have a little distortion.For improving impression quality, the Interal fixation of body of wall light current built-in fitting in template, flat with sponge adhesive tape lining between steel plate and template, build rear guarantee built-in fitting and body of wall in same plane.
When underplate concrete is built and is built with top board and walls concrete, to treatment of construction joints, for ensureing that constuction joint place is without bad root phenomenon, to help the formation of outseam, one time body of wall is poured into suitable for reading with steel form concordant, and carry out the floating process of press polish, be that two step formwork erections are prepared, and paste sponge adhesive tape in constuction joint bottom.
When underplate concrete is built and built with top board and walls concrete, vibrate closely knit, vibrate a little every 30cm mono-, anti-leak-stopping shakes.
The split bolt punch die that decoration exposed concrete construction method of the present invention is used, comprise a cylinder 1, the round platform 2 of protrusion is had outside cylinder upper end, cylinder lower end outside has external screw thread 3, round platform axis cross section is trapezoidal, and round platform upper end diameter is little, and lower end diameter is large, on the external screw thread of cylinder lower end, cover has nut 4, cylinder endoporus 6 internal diameter 1.5cm; This split bolt punch die lower end is inserted in the hole template from template 5 front, and the external screw thread that nut is enclosed within cylinder from template back surface is tightened fixing; After building, form the tubaeform split bolt hole that mouth diameters is large, base diameter is little.This mould adopts steel mould.Split bolt punch die replaces the position of Plastic cap, avoids each side reason produced because of plug.
Performance analysis:
Decoration exposed concrete construction method is widely used with in engineering.Compare through case history, adopt opposite-pulling bolt mold construction cost higher, but the later stage repairs decoration relatively, provides cost savings, serves good economic benefit and social benefit.
Application example:
Engineering name: Jinan City two ring West Road ground level road and environmental construction engineering
Starting date: on August 3rd, 2012
Completion date: on November 28th, 2012
Project site: ring West Road, Huaiyin District, Jinan City two
Because this engineering is Jinan City's key project, comprise the pipe gallery section of viewing and emulating, long 96m.
In work progress, carried out the control in details respectively to critical process, the side of reinforcing bar is pricked, and the use of steel form, and the input of bolt hole mould, the change of each details, makes concrete structures overall appearance, has good impression quality.
