Abstract
The utility model discloses a connection structure of coincide section bar, including integrative extrusion moulding's big section section bar, the small cross section section bar of grafting intracavity in big section section bar, be equipped with the rib that offsets with small cross section section bar outer wall on every inner wall of big section section bar, the area of rib up end is less than the area of rib stiff end, be equipped with the moly -sulfide lubricant film on the contact surface of rib and small cross section section bar outer wall. Simple structure, simple to operate is swift, the cross -section of integrative extrusion moulding's big section section bar is a whole, can ensure that these some intensity of material are not weakened, need not to add fastener such as bolt and reaches use intensity, the moly -sulfide lubricant film that is equipped with on the contact surface of rib and small cross section section bar can reduce the resistance when pegging graft, makes things convenient for assembly operation.
Description
Technical field
The utility model relates to curtain wall installing area, is specifically related to a kind of syndeton of superimposed section bar.
Background technology
Aluminium Baogang section bar is the external sheath aluminium extruded sections in steel profile, and the design of curtain wall keel now also more adopts aluminium Baogang section bar, can guarantee the attractive in appearance of profile while meeting intensity.The congruent manner of existing aluminium Baogang section bar comprises two kinds: one adopts to close chamber aluminium extruded sections, steel aluminium extruded sections is superimposed by the mode of poling, the sectional dimension of aluminium extruded sections is greater than the cross section of steel profile, after penetrating, gap is between the two often larger, fill in plastic cushion in gap to fill, but because difficulty during rear plug is larger, it is all often plunger type material two head part, increase external screw at the mid portion of section bar to connect, this way is installed comparatively loaded down with trivial details, and behind screw location, two section bars are fixed, can not be shifted.Another kind of mode adopts pin-connected panel aluminium extruded sections, one side of aluminium extruded sections is movable opening, steel profile puts into aluminium extruded sections from opening part, again by assembled for aluminium extruded sections opening cover plate, good fit clearance can be obtained between this structural iron aluminium extruded sections, but due to the principal part opening of aluminium extruded sections, the Compression Stability of chamber wall list limb is poor, the cross section performance of aluminium extruded sections closes lumen type material well below same cross-sectional size, also need to make enough external screws during construction to fix, the compatibility of deformation in guarantee cross section.
Summary of the invention
The utility model overcomes the syndeton that existing defect provides a kind of superimposed section bar, and adopt closed section intensity high, interspersed connection is easy to assembling.
The utility model is achieved through the following technical solutions:
A kind of syndeton of superimposed section bar, comprise big cross section section bar, the light section section bar be plugged in big cross section section bar inner chamber of one extrusion molding, each inwall of described big cross section section bar is provided with the rib offseted with light section section bar outer wall, the area of described rib upper surface is less than the area of rib fixed end, and the contact surface of described rib and light section section bar outer wall is provided with molybdenum sulfide lubricating layer.
The further improvement project of the utility model is, described big cross section section bar is aluminium extruded sections, and described light section section bar is steel profile.
The further improvement project of the utility model is, the contact surface of described rib and light section section bar outer wall is rectangle.
The further improvement project of the utility model is, the material of described rib is identical with the material of big cross section section bar.
The further improvement project of the utility model is, described rib adopts composite nylon plastics to make.
Compared to the prior art the utility model has the following advantages:
The utility model structure is simple, only light section section bar need be inserted in the inner chamber of big cross section section bar during assembling, quick and easy for installation; The cross section of the big cross section section bar of one extrusion molding is an entirety, can guarantee that the intensity that material originally has is not weakened, without the need to setting up the securing members such as bolt to reach working strength; The upper surface area of rib is less than the area of fixed end, make the contact surface area of rib and light section section bar less, reduce frictional force during assembling, in addition the molybdenum sulfide lubricating layer that is provided with of the contact surface of rib and light section section bar, resistance during grafting can be reduced further, operation convenient for assembly.
Accompanying drawing explanation
Fig. 1 is the utility model sectional schematic diagram.
Detailed description of the invention
The syndeton of a kind of superimposed section bar as shown in Figure 1, comprise big cross section section bar 1, the light section section bar 2 be plugged in big cross section section bar 1 inner chamber of one extrusion molding, each inwall of big cross section section bar 1 is provided with the rib 3 offseted with light section section bar 2 outer wall, coordinates closely without the need to setting up other securing members.The area of rib 3 upper surface is less than the area of rib 3 fixed end, can reduce friction area during assembling, thus reduces resistance.Rib 3 is provided with molybdenum sulfide lubricating layer 4 with the contact surface of light section section bar 2 outer wall, significantly reduces the resistance of assembling, convenient installation.
In the present embodiment, big cross section section bar 1 is aluminium extruded sections, and light section section bar 1 is steel profile, is conventional aluminium armored structure, and not only intensity is high but also appearance looks elegant.Rib 3 is rectangle with the contact surface of light section section bar 2 outer wall, and can fit completely with steel profile outer wall, intensity is high.The material of rib 3 is identical with the material of big cross section section bar 1, is convenient to shaping.Rib 3 also can adopt composite nylon plastics to make, the noise collided between section bar when can reduce installation.
