The closed cross section fiber-reinforced resin composite material hollow section has the advantages of simple structure, high stability and low cost, and is corrosion-resistant.
Description
Technical field
The utility model relates to the section bar manufacture technology field, and particularly a kind of closed type cross section fibres strengthens the resin composite materials hollow profile.
Background technique
Angle steel is because its easy to connect being widely used in traditional structure steel fabrication though its intensity is high, also exists weight big; Corrosion-prone problem for addressing these problems, also has the composite material of employing to make section bar; But the modular ratio steel of existing composite material are much lower; Adopt composite material to make when the section bar of angle steel same cross-sectional is used for force structure and is connected, be easy to occur unstable phenomenon, for avoiding this phenomenon generation; Often waste of material is caused at double increasing section bar cross section.
Summary of the invention
The purpose of the utility model is to provide a kind of saving material, good stability, corrosion resistant closed type cross section fibres to strengthen the resin composite materials hollow profile.
The purpose of the utility model realizes through following technical proposals:
The closed type cross section fibres of the utility model strengthens the resin composite materials hollow profile; It is characterized in that the right angle type load section that vertically is provided with boss by two limb edges forms with the supplemental support section that is connected these right angle type load section two limb edge lug boss; The thickness of said supplemental support section is 0.2-0.8 times of described right angle type load section thickness; Described boss height is greater than 3mm, and described boss thickness is greater than the thickness of supplemental support section.
The right angle type supplemental support section that the vertical section that described supplemental support section is connected with horizontal segment therewith by horizontal segment constitutes.
Described supplemental support section is a tilting supplemental support section.
Described supplemental support section is an arc supplemental support section.
Described supplemental support section is by horizontal segment, the arcuate segment that is connected of horizontal segment therewith, the supplemental support section that constitutes of the vertical section that is connected of arcuate segment therewith.
The characteristics that the closed type cross section fibres of the utility model strengthens the resin composite materials hollow profile are:
The right angle type load section that vertically is provided with boss by two limb edges is an evagination closed type structure with the cross section that the supplemental support section that is connected these right angle type load section two limb edge lug boss is constituted; The supplemental support section mainly plays stabilization; Its thickness is saved material than the thin thickness of right angle type load section.Right angle type load section is thicker; Can offer screw is used to connect other section bar and transmits stressed; On right angle type load section, offer the corresponding supplemental support section in screw place and formed auxiliary hole by part or all of excision, the hand that is used to lay link and workman carries out clamping bolt with instrument to be operated.Two limb edges vertically are provided with the moment of inertia that boss has increased right angle type load section on the one hand; Improved stability; In addition when offering auxiliary hole on the supplemental support section; Corresponding right angle type load section two limb edges will produce the stress concentration phenomenon, boss is set here will reduces the concentrated action effect to two limb edges of stress, improve the stress performance of section bar.Also have when the power of transmitting perpendicular to the section bar axial direction, available link blocks boss and replaces offering screw and realize power transmission, and this kind stability of structure is good, connects the same conveniently with angle steel with other member, can substitute angle steel and be used for multiple structure.The also available arc transition of the external frame sharp corner of section bar is to reduce the damage of colliding with.
The utility model is simple in structure, good stability, and cost is low, and is corrosion-resistant.

Embodiment
Embodiment below in conjunction with description of drawings the utility model.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5; The closed type cross section fibres of the utility model strengthens the resin composite materials hollow profile; It is characterized in that the right angle type load section 1 that vertically is provided with boss 4 by two limb edges forms with the supplemental support section that is connected 1 liang of limb edge lug boss 4 of this right angle type load section; The thickness of said supplemental support section is 0.2-0.8 times of described right angle type load section 1 thickness; Described boss 4 height are greater than 3mm, and described boss 4 thickness are greater than the thickness of supplemental support section.Two limb edges vertically are provided with the moment of inertia that boss 4 has increased right angle type load section 1 on the one hand; Improved stability; In addition when offering auxiliary hole 8 on the supplemental support section; Corresponding 1 liang of limb edge of right angle type load section will produce the stress concentration phenomenon, boss 4 is set here will reduces the concentrated action effect to two limb edges of stress, improves the stress performance of section bar.Also have when the power of transmitting perpendicular to the section bar axial direction, available link blocks boss 4 and replaces offering screw 9 and realize power transmission, and this kind stability of structure is good, connects the same conveniently with angle steel with other member, can substitute angle steel and be used for multiple structure.And the thickness of supplemental support section is saved material than the thin thickness of right angle type load section 1.Because right angle type load section 1 is thicker, can offers screw 9 and be used to connect other section bar and transmit stressed simultaneously.The also available arc transition of the external frame sharp corner of section bar is to reduce the damage of colliding with.
Right angle type supplemental support section as shown in Figure 1, that the vertical section 3 that described supplemental support section is connected with horizontal segment 2 therewith by horizontal segment 2 constitutes.
As shown in Figure 2, described supplemental support section is a tilting supplemental support section 5.
As shown in Figure 3, described supplemental support section is an arc supplemental support section 6.
As shown in Figure 4, described supplemental support section is by horizontal segment 2, the arcuate segment 7 that is connected of horizontal segment 2 therewith, the supplemental support section that constitutes of the vertical section 3 that is connected of arcuate segment 7 therewith.
The utility model is simple in structure, good stability, and cost is low, and is corrosion-resistant.
