Description

A kind of construction formwork back cord
Technical field
The utility model relates to formwork construction technology field, particularly a kind of construction formwork back cord.
Background technology
In order to reduce the consumption of the energy and resource, slow down the destruction to environment, the Chinese government, immediately following world trends, has promulgated " green building assessment standard ", has and then issued " Green Construction Guidelines " at the beginning of 2006, actively carries out green building construction.Building operations time in whole building life is very short, but it is very large on the impact of environment, and the consumption for resource and the energy is also concentrate very much.So, Green to build, must green construction be carried out.Green construction refers in engineering construction; under the prerequisite of basic demands such as ensuring the quality of products, safe; by scientific management and technological progress, economize on resources to greatest extent and the construction activities reduced environment negative effect, realize energy-conservation, save land, economize on water, four joint and environmental protection of material-saving.In building operations, template, scaffold are widely used as a kind of circulation material that can be recycled and facility.Therefore, the basic demand that the construction formwork system under green construction requirement must meet is: 1. consumed energy is less as far as possible; 2. do not produce for environment or to the greatest extent few produce harm; 3., during actual product uses, the repeatability that as far as possible can realize more times number utilizes; 4., when expecting discarded, can reasonably harmless treatment, resource recycling utilize as far as possible; 5. at this stage, must there be the reliable recovery system that can ensure that above-mentioned requirements realizes in manufacturer, or ensures that product can realize innoxious degraded completely in nature.
In " Green Construction Guidelines ", template, scaffold, as circulation material and facility, have highlighted: 1. should select durable, safeguard and the circulation material of convenient disassembly and facility; 2. preferentially select making, installation, remove integration professional contingent carry out form work engineering construction; 3. template to save natural resource for principle, should promote the use of sizing punching block, steel framework bamboo mould, bamboo slab rubber; 4. before construction, the scheme of reply form work engineering is optimized.Multilayer, highrise building use the template system that can reuse, and shuttering supporting should adopt tool bracing; 5. the external scaffolding scheme of highrise building is optimized, the scheme such as adopt Integral lifting, segmentation to encorbelment; 6. the technology adopting external wall insulation to substitute concrete construction formwork is promoted; 7. take the material-saving measure of effective technology and management, improve the number of turnover of template, scaffold etc.; 8. the research and apply of Construction Technology of Fair Faced Concrete and new type formwork and Construction Formwork & Scaffold Technology will be greatly developed.
In building concrete work progress, the lateral pressure that general template produces when being and can not bearing concreting completely, therefore usually need to arrange the rigidity that back cord strengthens template, existing most of back cord can not combinationally use, mostly back cord opposite formwork is man-to-man processing, all needs again to prepare new corresponding back cord when carrying out new concreting at every turn, and material therefor can not repeat recycling, very waste material, produce more building waste.
Utility model content
The purpose of this utility model be to provide a kind of material-saving, lightweight, durable, safeguard the construction formwork back cord with convenient disassembly, emissions reduction, solve that existing most of back cord can not combinationally use, mostly back cord opposite formwork is man-to-man processing, all need again to prepare new corresponding back cord when carrying out new concreting at every turn, technical barrier that material therefor can not repeat recycling, very waste material, produces the back cord waste of material of more building waste.
For achieving the above object, the utility model adopts following technical scheme:
A kind of construction formwork back cord, comprise two back-to-back channel-section steels be arranged in parallel and the connector connecting two channel-section steels, it is characterized in that: described channel-section steel is C type channel-section steel with holes, its frange plate has along C type channel-section steel bearing of trend the slotted hole that row are connected with template for back cord; Described connector comprises the U-shaped card between several webs being stuck in two channel-section steels, and the biside plate plate face of described U-shaped card is parallel with the web plate face of both sides channel-section steel and be connected and fixed with web respectively.
Preferably, the biside plate of described U-shaped card and web are welded to connect.
Preferably, described U-shaped card is by the thick rectangle steel plate cold roll forming of 10mm, and comprise the rectangle side plate on both sides and middle circular arc portion, described rectangle side plate is of a size of 100*30*10; Described circular arc portion is semicircular ring, and the internal diameter of semicircular ring is 24mm, and external diameter is 3mm.
Preferably, the number of described U-shaped card is at least two, is located at the two ends of channel-section steel respectively.
Preferably, the width of described slotted hole is 18mm, and length is 54mm, and the spacing of adjacent slotted hole is 325mm.
Compared with prior art the utility model has following characteristics and beneficial effect:
1, the utility model structure is simple, lightweight, and installation and removal rapidly and efficiently;
2, draw materials conveniently, the turnover that can circulate uses, and reduces construction cost, improves efficiency of construction, can be used as the back cord of concrete blinding, effectively reduce the stressed span of template, the distortion of constraint template;
3, the use of U-shaped card can facilitate the distance of control two channel-section steels, controls the overall width of back cord, makes and simply raises the efficiency.
