Abstract
The utility model discloses a pin-connected truss girder, which comprises a plurality of main girder standard sections and connecting plates, wherein each connecting plate is arranged between adjacent two main girder standard sections. One end of each connecting plate is fixedly installed at one end of one main girder standard section through a fixing device, and the other end of each connecting plate is fixedly installed at the end part of the adjacent main girder standard section through a plurality of pin shafts and split pins matched with the pin shafts. A through hole is formed in one end of each pin shaft, and each split pin penetrates in each through hole. The two adjacent main girder standard sections are fixed together through the pin shafts. When the length of the truss girder is increased, in order to correspondingly increase the strength of joints, only several pin shafts are added at the joints. The structure is beneficial to the standardization of the product.
Description
Technical field
The utility model relates to a kind of lattice girder, particularly the interconnection technique of lattice girder assembling.
Background technique
Lattice girder generally is fixed together by connection set by some girder standard knots, traditional connection set comprises a plate and the bearing pin that diameter is larger, connecting plate one end is fixed on an end of a girder standard knot in advance, the other end is fixedly connected with another girder standard knot by a larger bearing pin of diameter, when lattice girder length is larger, consider the relation of intensity, above-mentioned Placement generally satisfies the requirement of structural strength by the diameter that strengthens bearing pin.This mode is unfavorable for the standardization of product, is necessary existing product is improved design for this reason.
The model utility content
In order to address the above problem, the utility model provides a kind of lattice girder that adopts pin to connect.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of lattice girder that adopts pin to connect, comprise some girder standard knots and be arranged on connecting plate between the adjacent two girder standard knots, connecting plate one end fixedly mounts a therein end of a girder standard knot by fixing device, the other end of described connecting plate reaches the end that the cotter pin that cooperates with bearing pin is fixed on another girder standard knot by some bearing pins, described bearing pin one end is provided with through hole, and cotter pin is arranged in this through hole.
Described fixing device comprises some riveting pins.
The beneficial effects of the utility model are: adopt the utility model of said structure by adopting a plurality of bearing pins that two girder standard knots are fixed together, when lattice girder length increases, be the corresponding intensity that increases the joint, only need the joint to increase several bearing pins and get final product, be beneficial to the standardization of product.

Embodiment
With reference to Fig. 1～Fig. 7, the utility model is a kind of lattice girder that adopts pin to connect, comprise some girder standard knots 1 and be arranged on connecting plate 2 between the adjacent two girder standard knots 1, connecting plate 2 one ends fixedly mount a therein end of a girder standard knot 1 by fixing device, the other end of connecting plate 2 reaches the end that the cotter pin 4 that cooperates with bearing pin 3 is fixed on another girder standard knot 1 by some bearing pins 3, bearing pin 3 one ends are provided with through hole, and cotter pin 4 is arranged in this through hole.Adopt the utility model of said structure by adopting a plurality of bearing pins 3 that two girder standard knots 1 are fixed together, when lattice girder length increases, be the corresponding intensity that increases the joint, only need the joint to increase several bearing pins 3 and get final product, be beneficial to the standardization of product.
As shown in the figure, fixing device adopts some riveting pins 5, and is easy to connect, and structure is attractive in appearance, firm.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments, and for example: fixing device can be bolt, perhaps connecting plate is directly burn-on, etc.Those skilled in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
