Abstract
The prefabricated reinforced concrete shutterings for the beams and columns of huilding frame and its installation technology are disclosed. The shutterings for bottom, sides and ends of beam are made up concrete and the pulling and retaining rings of reinforcing bars and the holes for inserting reinforcing bors of wall are pre-arranged. For the columns, the side shutterings are made of concrete and the reinforcing bars for linking walls and beams are pre-arranged. After walls and columns are assembled, the beams are put on vertical plane of columns. The main bars and reinforcing bars of columns and beams are inserted into each other. Its advantages are saving labour and time and low cost.
Description
The present invention relates to be used to make the template of construction wall, a kind of building frame beam scapus body prefabricated reinforced concrete template and installation technology.
At present, beam is constructed in building operations, the cylinder framework uses punching block, wooden model, bamboo mould, the plastic-steel mould is built steel concrete, it exists defective to be: above-mentioned mould is installed overlap joint, build then, roll over after the curing again and remove mould, need cleaning reparation, transportation often causes template damage in various degree, and building costs is raise.
The purpose of this invention is to provide a kind of building frame beam body, cylinder prefabricated reinforced concrete template and installation technology, standard size requirement according to beam body, cylinder, at first at the place prefab form, transport to the job site and assemble, and then concreting, treat concrete curing after, template directly and the main body concrete become one, do not need to remove, reduce construction cost, save man-hour.
For achieving the above object, the present invention adopts following technical scheme:
Described building frame beam body, cylinder framework prefabricated reinforced concrete template, on certain production site, according to building standard, adopt concrete for making beam body soffit formwork 1, group's template 2, the top template 3 at two ends, the template bottom surface is the light face, be hair side above, and bury embedded bar underground and draw clasp 6, reserve body of wall reinforcing bar jack simultaneously; Cylinder is according to building standard, adopts concrete for making to become cylinder group template 4,5, and each helps on the template pre-buried connection to draw fastener 6, reserves the reinforcing bar that is connected with body of wall beam body simultaneously.
Described building frame beam body, the mounting process of cylinder prefabricated reinforced concrete template, after its prefabricated reinforced concrete template was transported to the scene, stacking required side direction vertically to be close to stacking, needed to soak 4-6 before installing individual hour in the pond.
The on-the-spot mounting process of described building frame beam body, cylinder prefabricated reinforced concrete template.The steel concrete shuttering that to make at production site, be transported to the job site, when making the beam body beam body soffit formwork 1 caught and be located on the frame pipe, again group's template 2 and two ends top template 3 are installed in respectively on the beam body soffit formwork, adopt reinforcing bar to connect template and draw button 6,7 socket, and colligation, fuse with the main body beam main tendon, reinforcing bar is strained and fixed, and meets the beam body of architectural drawing standard profile size, and then direct concreting, treat its curing, body of wall cylinder group template adopts 6 reinforcing bars to make drag hook 7, connects template and draws clasp, colligation is fastening, support with scaffold, when check and correction meets architectural working drawing required standard appearance and size, build column body concrete again, treat its curing, remove support scaffolding and get final product.
The mounting process of described building frame beam body, cylinder prefabricated reinforced concrete template, after its wall column body assembling, the beam body is horizontally placed on the cylinder vertical plane, and in vertical main muscle of cylinder and the stiffener insertion beam body, the main muscle and the stiffener of beam body also insert in the cylinder simultaneously.
The mounting process of described building frame beam body, post prefabricated reinforced concrete template, when its template was installed, the template seam is handled as follows: the cement mortar with 1: 2 was constructed seam, adopt 425 cement, the template seam requires in 1-2MM, treats that template seam intensity reaches at 45% o'clock, begins to build the main body concrete.
Described building frame beam body, the mounting process of cylinder prefabricated reinforced concrete template, because of main body concrete adstante febre needs moisture content, so after the main body concreting, necessary maintenance 15-18 days.
Owing to adopted as above technical scheme, the present invention has following superiority:
Carry out the concrete work main body with the prefabricated reinforced concrete template and build, build finish after, treat that the major project concrete strength reaches at 75% o'clock, scaffold removed got final product, the prefabricated reinforced concrete template just need not be removed, time and labour saving, attenuating expense.
The precast concrete form installation is built the main body concrete and can be become one with Vierendeel girder, post.Being not template during concreting after the installation, also is the topping of reinforcing bar simultaneously, has built concrete and has just become the body frame external surface of body, cylinder of setting a roof beam in place, so just need not remove.
The prefabricated reinforced concrete template is without timber, without steel.Reduce forest, the waste of iron ore deposit.
The prefabricated reinforced concrete pattern plate bolster body of setting a roof beam in place; column body concrete does not increase the profile physical dimension; undertaken by the working drawing standard; controlled and the protection of the attached reinforcing bar of major project master; make and do not reveal the main body reinforcing bar, the prefabricated reinforced concrete template only need be installed, and need not remove; saving of work and time has reduced cost.
The prefabricated reinforced concrete form technology is simple, and is easy to operate, small investment, instant effect.
The production technology of prefabricated reinforced concrete template, require producing prefab form factory has a smooth place, and the producer that can produce various precast concrete forms just can.
The prefabricated reinforced concrete template belongs to disposable tool-typed formwork, and is technical strong, requires physical dimension accurate.
The prefabricated reinforced concrete template strength reaches 100% and can dispatch from the factory, and dispatches from the factory and must show the concrete pressure test sheet.
Prefabricated reinforced concrete template major economic indicators.
