Description
Technical field
The present invention relates to a kind of construction steel structure, relate in particular to a kind of syndeton of lightgage steel joist.
Background technology
High speed development along with builing industry, New Building Materials continue to bring out, and as the lightgage steel joist of New Building Materials since its have lightweight, intensity is high, the performance of waterproof, fire prevention, many excellences such as shockproof, easy to install is applied in the various building structure more and more widely, using lightgage steel joist to make up in the process of structure, must often need to will couple together between the different lightgage steel joists, what this connection was generally adopted is the mode of welding, being spirally connected or riveting.
In conjunction with the situation that current light steel is used, the syndeton when above-mentioned lightgage steel joist connects need to satisfy certain requirement: 1. requirement of strength, such as static strength, fatigue strength etc.; 2. dimensional requirement is such as the center to center distance between screw, bolt or the rivet and the single center required distance to any limit; 3. rigidity requirement should be enough strong such as the rigidity of structure, and distortion should be little of being unlikely to cause that attached finishing material such as gypsum plank thereon ftractures, breakage during the opposing external load; 4. technological requirement, this structure should easily realize processing, and process is simple, operation is reliable, steady quality; 5. in addition, from the structure design angle, adopt the design of this syndeton should have certain advantage at aspects such as material costs, if play the effect of lightening material weight, reduction material cost.
The mode that employing is weldingly connected, although can satisfy the requirement of above-mentioned intensity, size and rigidity aspect, but this kind connected mode is non-removable connection, the material regeneration usability is poor, operate comparatively complexity and environmental pollution larger, so more common or adopt the mode that is movably connected that is spirally connected or rivets.
For so that adopt the syndeton of the lightgage steel joist of the mode that is movably connected to satisfy above-mentioned bonding strength requirement; usually can consider to increase the diameter of connector; but; the thickness of steel product used owing to lightgage steel joist is thinner; and syndeton also must satisfy above-mentioned dimensional requirement; therefore the diameter of the used connectors such as screw, bolt or rivet can't accomplish very large, so can't be by the method so that syndeton reaches very high requirement of strength.
And, the connection structure of light gage steel joist of existing employing movable connection method also can't reach good rigidity requirement, be described as follows: be a typical light steel wall structure as shown in fig. 1, wherein the figure in left side is the light steel wall structure under the normal not stressing conditions, the figure on right side is the light steel wall structure after the stress deformation, as can be seen from Figure 1 in the situation that adopt existing syndeton, although the slant-pull structure of strengthening rigidity is also arranged in the structure, but structure edge in face still can be out of shape the angular direction, this point can be clearly when assembly structure, that is: in the figure in left side as with B point fixed constraint, apply lateral thrust at the D point, the distortion that then can find out structure this moment from the figure on right side is very obvious, high take a 2800() * 3800mm(is wide) light steel wall as example, when when the D point applies 40KG load, when diagonal AC and BD length difference will reach 60mm(and not be out of shape diagonal poor be 0), this distortion easily causes structure itself and is attached to finishing material on the light steel such as the destruction of gypsum plank etc.
Also have, because existing connection structure of light gage steel joist can't reach very high intensity and rigidity requirement, thereby this syndeton in use, usually must guarantee by the density of arranging that increases the lightgage steel joist on the light steel composite member stability of composite member, so also just can't satisfy well lightening material weight that above-mentioned syndeton need satisfy, reduce the requirement of material cost.
Summary of the invention
