Description

The high-performance steel scaffold floor

The utility model is a kind of with special thin checkered steel plate punching press and add the vertical rib of weldering and strengthen, and the head and the tail joint adopts group's iron to reinforce the thin Steel scaffold board (calling this scaffold floor in the following text) of spreading, belongs to the building operations apparatus.

Scaffold floor is to use very general a kind of building operations apparatus, in the construction of the masonry residential below seven layers, building materials such as the concrete that gets on combination derrick and self lift type door frame elevator, mortar, brick all will be done the level transportation by scaffold floor, arrive construction part; Lay bricks, plaster and fit up, generally also will use scaffold floor.

The kind of scaffold floor is a lot, and wooden scaffold floor, bamboo scaffold floor, shaped steel scaffold floor, shaped steel diveder scaffold floor are arranged, and thin Steel scaffold board etc. all have introduction in multiple building operations books.The wood scaffold floor is from heavy and light, and intensity is higher, and non-skid property is better, easy to use, P Passable skid platform above it, the timber source is wide before adding, low price, wooden scaffold floor also can be used to make wooden door and window, furniture, hand-held tool etc. after using, thereby uses still the widest so far.But wooden scaffold floor will consume the timber of a large amount of preciousnesses, and generally seven layers of brick with door frame or derrick handling mix housing construction, uses wooden scaffold floor to need 10 meters approximately ³Above timber; The wood scaffold floor exposes to the sun and rain all the year round, and only be about 2～3 years application life, and it is very big that therefore wooden scaffold floor year consumes amount of wood.The forest reserves are very low per capita owing to China, after in October, 1998 implementation taboo is cut down natural forests, and timber imbalance between supply and demand anxiety.According to literary composition report on November 24 " China Economic Times " in 1998 " China lumber market attracts people's attention " one, from 2000 to 2010, China's economic construction usefulness material year breach will be by 4000 myriametres ³Rise to 9000 myriametres ³Simultaneously, because the progressively large-scale popularization of plastic door-window, plastic-steel door and window is used, the timber index of construction project must be kept under strict control, and can not continue to make wooden scaffold floor with a large amount of timber.

Bamboo scaffold floor intensity is lower, and rigidity is poor, rocks in the use greatly, and angle steel, channel-section steel weld the heavy inconvenience of scaffold floor with steel plate (or reinforcing bar), and intensity is low; Equilateral or unequal angle is done the frame embedding still will consume timber with the wooden scaffold floor of the steel of plank, and intensity is low, and rigidity is poor; Make the steel wood scaffold floor intensity height of frame with channel-section steel, but it is excessive to conduct oneself with dignity, every meter reaches 14 kilograms, and the workman uses painstaking inconvenience, influences safety, and will consume timber; In the thin Steel scaffold board, though the intensity of patent No. ZL96233479.0 high strength steel scaffold floor, rigidity greater than other various thin Steel scaffold boards, but still can not satisfy the requirement of current trolley.At present nearly all other various scaffold floors all hold and can't stand current fully loaded trolley except that wooden scaffold floor, and this has just limited applying of these scaffold floors greatly.

The purpose of this utility model, be intensity, the rigidity that further improves this scaffold floor, make it have high non-skid property, make the spreading use arbitrarily of this scaffold floor by group's iron connection, and the intensity of joint is equated substantially with the intensity of this scaffold floor own, and realize the fully loaded hand barrow that can pass through, substitute wooden scaffold floor effectively thereby can have, with steel for wood, the forest tree resource of saves valuable.

This scaffold floor structure is seen accompanying drawing.(just drawn a side board 10 among the figure typically, need another piece scaffold floor and all the other side boards of spreading not shown, the surface Argyle only illustrates partly) 1 be mainboard among the figure, 2 is butt hook, 3 is the end rib plate, 4 is middle floor, and 5 are vertical rib, through spelling, be welded into integral body and handle back one-tenth product through antirust japanning again.The 6th, wing nut, the 7th, pulling plug, the 8th, wedge, the 9th, fastening card, the 10th, side board.

Mainboard 1 adopts the thin checkered steel plate of spy of the basic thickness 1.4～2mm of steel mill's customization, makes its non-skid property all be better than various existing scaffold floors.(but before steel mill's customization supply of material, can adopt general steel sheet to make, and the flared hole anti-skid structure of employing patent ZL962334790 high strength steel scaffold floor) form of structure of the above-mentioned patent high strength steel sole of good mechanical properties is adopted in rib cross section, the end, makes mainboard have high intensity and rigidity.Two ends, mainboard side dash altogether 8 tilting rectangular openings, can be for packing fastening card 9 into, penetrate the rectangular opening on the side board 10, squeeze into wedge 8 again, can make two these end to end scaffold floors, securely link together by side board, the joint and any spreading of the basic equal strength of plate itself that reach this scaffold floor use, thereby make the fully loaded trolley of this scaffold floor P Passable, also can avoid scaffold floor end probe overlength to cause and stick up the trouble of turning over or need set up support in the termination.Equidistant hole, garden of arranging, mainboard 1 both sides promptly can bind by iron wire and scaffold cross bar (steel pipe, rod or bamboo bar), also can two adjacent these scaffold floors arranged side by side are tight with the iron wire bolt, can also run through the mainboard 1 of two scaffold floors and the circular hole on the vertical rib 5 by pulling plug 7, wing nut 6, two these scaffold floors arranged side by side are connected.Vertical rib 5, accompanying drawing is depicted as 1, but also can be 2 or many, and cross sectional shape can be " T " font, " worker " font, " L " font, trapezoidal, rectangle or other shapes.Behind vertical rib 5 and mainboard 1 assembly welding, bulk strength, rigidity and the plate face supporting capacity of this scaffold floor all are greatly improved.Circular hole on vertical rib 5 also can bind by iron wire and scaffold cross bar.Mainboard 1 two ends respectively are welded with on end rib plate 3, the one end end rib plates 3 and are welded with 2 butt hooks 2,3 no butt hooks of other end end rib plate.When two these end to end scaffold floors only need generally articulate and when not needing equal strength affixed, only need the end rib plate on the scaffold floor, hang in the butt hook of another piece scaffold floor end and get final product, and side board 10 annexes such as grade needn't be installed.Floor 4 in the middle of is arranging at a certain distance vertical rib 5 both sides below the mainboard 1, this floor and mainboard 1, vertical rib 5 assembly weldings are integral.The grab assembly that this scaffold floor also can be used patent ZL96233479.0 high strength steel scaffold floor is connected with the cross bar of steel pipe scaffold.

The utility model is compared the beneficial effect that is had with background technology, the one, the strength and stiffness of this scaffold floor are greatly improved, solved the problem that nearly all is difficult to current trolley on the present various scaffold floors except that wooden scaffold floor, when being used for external scaffolding, can reach the requirement of three layers of brick of side-sway of building operations regulation and stipulation easily, increase the spacing of scaffold upright rod morely, reduce the hack lever consumption, reduce construction cost; Bending, distortion, the buckling deformation that can reduce scaffold floor damage, and increase application life.The 2nd, because mainboard has adopted special thin decorative pattern (rhombus or other shapes) steel plate, improved the non-skid property of scaffold floor greatly, increased safety in utilization.The 3rd, increased the side board connection in scaffold floor head and the tail joint, make the flexural strength of joint reach the intensity of scaffold floor self substantially, realize that any spreading of equal strength uses, this is to comprise that at present the various scaffold floors of wooden scaffold floor are not available.The 4th, because the limit rib and vertical rib 5 upper punches of mainboard 1 have a plurality of circular holes, can pass through pulling plug 7, wing nut 6, two scaffold floors arranged side by side are linked, also can be tight with the hack lever bolt easily through circular hole with iron wire.Because this scaffold floor has above multiple advantages, the optimal substitute of wooden really scaffold floor is saved timber, convenient construction.

This scaffold floor manufacture craft is easy, and common mechanical factory can both produce.Wherein the mainboard making is complicated slightly than other parts, and activities can be considered as follows:

1. to the special thin checkered steel plate of steel mill's customization;

2. press the length and width size shear blanking that mainboard launches, to off sizely suitable welding jigsaw, using through smoothing;

On the forcing press at the bottom of mould is successively respectively with both sides the rib bending forming;

4. rectangular opening and the circular hole on the rib of stamping-out limit.

When production lot is very big,, reduce cost for improving work efficiency, can consider to manufacture and design plate bending rolls, adopt the special decorative pattern roll bending of thickness width scale, mainboard 1 is organized roll one-time continuous rollformings through more, fixed ruler cutting, stamping-out rectangular opening and circular hole then.

Vertical rib 5, when this scaffold floor height was 55mm, adopting highly was the GB2597-81 hot rolling casement section steel 5007 "T"-shaped finished steels the most convenient, economic (accompanying drawing is by this drafting) of 50mm, only needs during making to get final product assembly welding after fixed ruler cutting, the punching.

The manufacture craft of these other parts of scaffold floor and spelling, welding, enamelling process are comparatively simple, do not give unnecessary details now.
