The specific embodiment
Embodiment is shown in Figure 1, and this biplate, to holding card tool, has bolt hole 1.3 and wire rope perforation 1.4 on the plate body 1.1 of described link plate 1; Bolt hole 1.3 on described plate body 1.1 has two and be positioned at same level line; Wire rope on described plate body 1.1 perforation 1.4 is positioned at the below, triangular in shape with bolt hole 1.3 of bolt hole 1.3; The top edge of described plate body 1.1 extends upward a horizontal curved to the upper arm 1.2 of plate body one side, and the width of described upper arm 1.2 is less than the width of plate body 1.1 wide ends; Described plate body 1.1 is wide at the top and narrow at the bottom, and the base angle in outside is top rake; The knuckle of described link plate 1 is chamfering.
Shown in Figure 2, this biplate is to holding card tool, two link plates 1 be symmetrical in shaped steel web, be connected to the bottom flange of shaped steel, the bottom flange that gap between upper arm 1.2 and plate body 1.1 can hold shaped steel, the symmetrical superimposed connection of part plate body of two link plates 1, the upper arm of two link plates 1 is symmetrically distributed in the both sides of shape steel web, now the bolt hole on two boards body 1.1 1.3 overlaps and is positioned at the below of shape steel web, and connecting bolt 2 is fixedly connected with two link plates 1 through the bolt hole 1.3 overlapping on two boards body 1.1 successively.
Shown in Figure 3, a kind ofly apply the method for attachment of described biplate to holding card tool, concrete steps are as follows:
Step 1, blocks the bottom flange of H shaped steel 7 by two link plates from the both sides of H shaped steel.
Step 2, the part plate body of two link plates overlaps, fastening through the bolt hole overlapping on two link plates successively by connecting bolt 2.
Biplate is connected with H shaped steel holding card tool, as the fixed connection point on shaped steel, can has multiple use.
For example, shown in Figure 4, the bottom flange of H shaped steel 7 is snapped in respectively to biplate between the upper arm 1.2 of holding card tool and plate body 1.1, by connecting bolt 2, be connected and fixed two link plates 1, and place capels 3 in wire rope 1.4 inner sides of boring a hole; Afterwards wire rope 6 is passed to capel 3, wire rope one end connection scaffold or cantilever steel girder, the other end application of force, can utilize biplate is fulcrum to holding card tool, scaffold or cantilever steel girder are hung and move position to, like this without the external corner of H shaped steel is taked to safeguard procedures, simple, guaranteed efficiency of construction, in addition, biplate can also be connected with hanging basket holding card tool, or be connected with hoist engine, play the effect of convenient construction operation, and biplate is very reliable with being connected of shaped steel to holding card tool, can be according to on-site actual situations flexible Application.
In addition, biplate can also be for the connection construction of structural steel beam and cantilever steel girder to holding card tool, shown in Figure 5, while carrying out structural steel beam 4 and cantilever steel girder connection construction in 5 morning, the bottom flange of structural steel beam 4 is snapped in respectively to biplate between the upper arm 1.2 of holding card tool and plate body 1.1, now, need to prepare two cover biplates to holding card tool, be connected and fixed with structural steel beam 4 simultaneously, and be separately positioned on the both sides of cantilever steel girder 5, on cantilever steel girder 5, have screw, then, connecting bolt 2 is successively through the bolt hole 1.3 of first set biplate to holding card tool, the screw of cantilever steel girder 5, the second cover biplate is fixedly connected with three the bolt hole 1.3 of holding card tool simultaneously, in order to guarantee bonding strength, can also increase the wire rope perforation 1.4 of a screw bolt passes first set biplate to holding card tool, the screw of cantilever steel girder 5, the wire rope perforation 1.4 of the second cover biplate to holding card tool, this connected mode is simple and easy to do, and without perforate in structural steel beam, guaranteed the intensity of structural steel beam, be conducive to guarantee the safety factor of construction.
The size design of biplate to holding card tool, need to calculate according to the concrete size of member, according to structure analysis software SAP2000 calculate member to biplate the counter-force to holding card tool, be horizontal force and vertical force, again biplate is carried out to shearing resistance check to holding card tool, bending resistance is checked, draw the size of upper arm and plate body coupling part, also will be according to the suffered lateral stress size of upper arm, draw the height of upper arm, the thickness of link plate generally has 10mm or 20mm equal-specification, when if link plate thickness is 10mm, the size of upper arm and plate body coupling part is not less than 40mm, the height of upper arm is not less than 35mm, the wide H shaped steel of the 200mm of take is example, web thickness is 8mm, the clear space of the every side of that bottom wing listrium is about 96mm, remove the weld width between web and bottom wing listrium, the remaining 88mm that is about, so, the length of upper arm 1.2 is for being not less than 125mm, the length of link plate is not less than 150mm, the coincidence size of two link plates is not less than 1/3rd of H shaped steel width, the gap of upper arm and plate body can hold the bottom flange of H shaped steel, and the check of connecting bolt only need be checked the shear-carrying capacity of bolt, according to horizontal force and vertical force, draw with joint efforts, calculate the maximum shear that single connecting bolt bears, select suitable bolt model and quantity, for example, suffered while making a concerted effort for 19448N, select the bolt of 3 diameter 16mm, the net sectional area of the stainless steel bolt of diameter 16mm is 150.7mm
2, shear strength is 265N/mm
2, the shear-carrying capacity of bolt is 39940N, meet the demands completely.
