Abstract
The utility model discloses a novel tie rod, and the sectional plane of the tie rod forms a V shape. Both ends of the tie rod are provided with connecting ear plates, and connecting holes are arranged on the connecting ear plates. The tie rod is formed by bending steel plates, and an intersection angle of two side plates is 60 DEG. The connecting ear plates are formed by bending the prolongations of both ends of one side plate, and the connecting ear plates are perpendicular to the side plate. The tie bar adopts a V-shaped design, and can bear a draw-press two-dimensional stress; the utility model has the advantages of large stiffness, good stress performance, flexible and convenient connection, and free maintenance.
Description
The utility model relates to a kind of steel construction piece.
Can in the lightweight steel construction system, purlin and grit adopt the cold bending thin wall member more, so provide powerful lateral support that its supporting capacity and structural stability are had certain influence.Tie-rod is the member that lateral support is provided for purlin specially, so the effect of tie-rod can not be ignored.Usually tie-rod adopts the round steel two ends car silk of Φ 12, is connected with purlin with 4 nuts.This tie-rod has following shortcoming: 1) this kind tie-rod can only be as tension member, can not bear pressure, therefore can't significantly influence the supporting capacity of purlin for purlin provides powerful lateral support fully, and be difficult for keeping the straight of purlin member, influence attractive in appearance and stability.2) need to carry out paint work or zinc-plated processing after this member machines, so its durability can not show a candle to the purlin member of continuous hot-dipping galvanizing, this member is connected in the middle of the purlin in addition, safeguards quite difficulty in the future.Adopt when 3) installing and go up drop-down method, can cause the purlin distortion, cause as the buckling plate generation feint spike of K/D and so on and close phenomenon, and influence its bearing capacity, even blown away by high wind owing to it.
The purpose of this utility model is: a kind of novel tie-rod is provided, and this tie-rod adopts V-type design, can bear tension compression bidirectional stress, stiffness big, stressed good, connect flexiblely, and remove maintenance from.
The technical solution of the utility model is: a kind of novel tie-rod, the cross section of this tie-rod is V-shaped, and is provided with the connection otic placode at the two ends of tie-rod, connects otic placode and is provided with connecting hole.
The further technical scheme of the utility model is: a kind of novel tie-rod, and the cross section of this tie-rod is V-shaped, and is provided with the connection otic placode at the two ends of tie-rod, connects otic placode and is provided with connecting hole; Described tie-rod is formed by the steel plate bending, and the angle between the biside plate is 60 degree.
The more detailed technical scheme of the utility model is: a kind of novel tie-rod, and the cross section of this tie-rod is V-shaped, and is provided with the connection otic placode at the two ends of tie-rod, connects otic placode and is provided with connecting hole; Described tie-rod is formed by the steel plate bending, and the angle between the biside plate is 60 degree; Described connection otic placode is formed by the prolongation bending at certain side plate two ends, and it is perpendicular to connect otic placode and this side plate.
The utility model has the advantages that:
1. stiffness is big: adopt DESIGNING COMPRESSION RODS, tie-rod can bear tension compression bidirectional stress, can provide good lateral support for purlin, and the bearing capacity of purlin is given full play to, and reduces cost.
2.V type design: adopt the V-type design, its each to change radius approaching to enclosing, and can use minimum material, reaches the effect of the best, and process simply, convenient and swift, and economy is good.
3. connect flexible: be designed to the punching otic placode with the purlin junction, can use the bolt of M12, utilize the tie bar holes of former purlin, be connected on the purlin, also can on purlin, leave slotted hole, directly pass the crooked otic placode in back and connect.
4. stressed good: all tie-rods connect point-blank, and are stressed good, can not cause the distortion of purlin.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a right view of the present utility model;
Fig. 3 is an expanded view of the present utility model;
Fig. 4 is a user mode schematic diagram of the present utility model;
Fig. 5 is the partial enlarged drawing of Fig. 4;
Wherein: 1 tie-rod; 2 connect otic placode; 3 connecting holes; 4 side plates; 5 purlins.
Embodiment: as shown in the figure, a kind of novel tie-rod, the cross section of this tie-rod [1] is V-shaped, and is provided with connection otic placode [2] at the two ends of tie-rod [1], connects otic placode [2] and is provided with connecting hole [3]; Described tie-rod [1] is formed by the steel plate bending, and the angle between the biside plate [4] is 60 degree: described connection otic placode [2] is formed by the prolongation bending at certain side plate [4] two ends, and it is perpendicular with this side plate [4] to connect otic placode [4].
The utility model adopts with the purlin identical materials and makes, and antiseptic property is strong, makes its life-span identical with purlin, removes maintenance from.
