Description

H shaped steel dedicated fastener

Technical field

In recent years, the steel and iron industry sustained and rapid development of China, steel output improves rapidly, has become the first in the world big steel country.Structural steelwork has advantages such as environmental protection and energy saving, short construction period.The Chinese government has also proposed the policy of " greatly developing steel work ".

The construction work of present domestic high parameter, big capacity power plant adopts H steel beam structure form to increase year by year, and especially station boiler all is a steel work, and the overwhelming majority wherein is " H " formed steel construction.Along with the consideration of aspects such as antidetonation, construction, civilian super highrise building engineering is also used H formed steel construction form in a large number.Energy-conserving and environment-protective are more and more paid attention to by country, and China belongs to extremely lack of water country, for water intaking, water the very strict regulation of examining are arranged.At power field, Air-cooled Unit receives the concern of each big genco with the water-saving rate more than 70%, and the trend that rises is year by year held in installed capacity, and air cooling platform also all is a H formed steel construction form.

The utility model relates to construction work, power station construction field, and H formed steel construction or other have in the formed steel construction engineering construction of similar wing plate.Especially relate to the used special-purpose girder steel fastener that scaffolds erecting quick, safe on a kind of H of being used in section steel beam, the post.

Design " H " shaped steel scaffold is built special-purpose steel fastener.This fastener technology system is a patented product, is widely used in Construction of Steel Structure, compares with traditional handicraft, all obtains better economic benefits at aspects such as construction safety, programming, saving costs.Compare with my another patented technology " H section steel beam fastener " ZL200620006210.2, emphasis is having raising aspect economy, the safety.

Background technology

In the Construction of Steel Structure, aspect constructure scheme such as " the H girder steel column cap installation bracket " that needs in installing for node, the scaffold building that equipment is installed needs and platform concreting determine it is the emphasis of engineering construction.Now, all there are different constructure scheme, method in each unit in charge of construction, and big multi-scheme is not very desirable at aspects such as economy, safety, duration controls.

One, be example with H girder steel column cap installation bracket, at present, following several mode of building arranged:

1, regulation pattern in the operative norm " thermoelectricity construction safety facility " of country's promulgation, called after: combined type column cap carriage.And aspects such as relevant making, use have been made technical requirements.This kind form make to need with the major-minor cost of materials, mechanically takes, the hundreds of units of cost such as the electricity charge, labour cost, and installation, dismounting, maintenance etc. are extremely inconvenient, still less what use now.

2, national standard is simplified, used two angle steel, channel-section steel or other shaped steel, adopt mode the folder bolt.This mode also has many shortcomings, mainly is that the shaped steel of different size can not be general when installing, and the installation of carriage, removes inconveniently, and the initial stage drops into high, also causes the waste of great deal of steel.

3, contact structure steel fabrication producer directly at the correct position auger shell keyhole of H shaped steel wing plate, uses bolt that angle steel, channel-section steel or other shaped steel are fixed on the H formed steel construction.This mode has also caused permanent damage to steel work except that the shortcoming that possesses the second way.

Two, with equipment the scaffold building that needs being installed is example, at present, the following mode of setting up is arranged:

1, directly sets up the console mode scaffold.1., the job site scaffold is too much mainly have following technological deficiency:, inconveniences such as current, Construction Arrangement are unfavorable for safety; 2., need to use a large amount of scaffoldings; If physical dimension is excessive between 3. two-layer steel work, and is then inapplicable.

2, the scaffold of eminence adopts the method for on H shaped steel " packing hoop ", uses four scaffolding poles and four cruciform fastening for falsework that H shaped steel is wrapped, and sets up scaffold then on shroud ring.1., fixing insecure mainly there is following technological deficiency:, easily slide; 2., the cruciform fastening for falsework that uses very easily is damaged, and is major safety risks; 3., the material input, artificial drop into bigger.

Three, be example with the concreting of factory building platform, at present, following two kinds of form bracing systems arranged:

1, full hall scaffold support system.1., need to cause long construction period mainly there is following technological deficiency: with a large amount of scaffoldings; 2., need to transport, to install and to remove these materials with a large amount of personnel and machinery, machinery take, labour cost remains high; If 3. the interlayer level difference greatly then inapplicable.

2, lumps of wood support system.Mainly there is following defective: the timber that needs are a large amount of, need the lumps of wood with 100mm * 100mm, add up to every square metre to need with 0.04---0.05 cube, timber is disposable use basically, causes construction cost to increase and the wasting of resources.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technological deficiency, and a kind of saving cost is provided, and is in light weight, makes simply, be connected firmly, and convenient and quick construction, of many uses, and repeatedly used H shaped steel dedicated fastener.

As follows for realizing the technical scheme that the purpose of this utility model adopted:

A kind of attachment fastener of on H section steel beam (post), setting up scaffold, it is characterized in that: this fastener is made up of fastener body, fastening bolt and supporting hold-down nut, described fastener body is L shaped (or grooved) structure, have the circular hole that is used to pass scaffold tube on it, the bolt hole that fastening bolt passes fastener body is connected with supporting hold-down nut, and hold-down nut is embedded in the special-purpose groove of fastener body.

The utlity model has following technological merit:

1, weight is little, and single weight is below 1.5 kilograms;

2, versatility is good, can be used as purposes such as column cap installation bracket, the support of platform concrete casting building mould, installation scaffold building;

3, the safety that is connected firmly, convenient to disassembly, the scaffold moulding is attractive in appearance;

4, can prolonged and repeated turnover use;

5, do not need professional and technical personnel's on-the-spot guidance to install, scaffold building workman's spanner is general, does not need special spanner;

6, the thickness requirement to the steelframe wing plate is low, and thickness is being safe more than 8 millimeters;

7, utilize this fastener to form support system, the scaffolding of use minute quantity can be finished the support of steel structure platform concrete casting building mould, has the advantage of full hall scaffold support system and lumps of wood support system, saves the substantial contribution input.
