The utility model content
The purpose of the utility model provides a kind of power transmission tower frame, and it can overcome the defective of prior art, and existing pylon is carried out local stiffening, reaches the windproof requirement.
The utility model is achieved in that
A kind of power transmission tower frame; It includes many main materials, many horizontal materials and many oblique materials; Many said main materials, many said horizontal materials and many said oblique materials are cross-linked to form frame construction, are formed with a plurality of nodes on the said main material, said power transmission tower frame be provided with a plurality of reinforcement elements; Each said reinforcement elements includes many and reinforces horizontal material and the many oblique materials of reinforcing; The horizontal material of a plurality of said reinforcings connects the node that is on the same plane and forms the tabula face, and the many oblique materials of said reinforcing form the diagonal brace face, and said diagonal brace face is connected with said oblique face and is connected with said node.
Among embodiment, the spacing of adjacent two said tabula faces is less than or equal to the width of 5 times of said power transmission tower frames therein.
Among embodiment, said main material is that many raw material are connected to form therein, and the spacing of adjacent two said tabula faces is less than or equal to 4 times of raw-material length of each root.
Among embodiment, it also includes a plurality of cross bars therein, and the mid point of adjacent two horizontal materials of said reinforcing connects through said cross bar.
Among embodiment, said node place is provided with gusset plate therein, and said gusset plate is provided with a plurality of bolts hole, and horizontal material of said reinforcing and the oblique material of said reinforcing all are connected with said gusset plate through said bolt hole.
Therein among embodiment, said diagonal brace face be shaped as triangle.
The utility model power transmission tower frame compared with prior art has following beneficial effect:
The utility model power transmission tower frame through existing power transmission tower frame is carried out stress analysis, confirms that weakness zone (the weak zone of wind loading rating) for needing reinforcing area, sets up reinforcement elements, reaches the purpose of reinforcing power transmission tower frame; This reinforcement elements utilizes the gusset plate at the node place on the former power transmission tower frame and bolt hole to be arranged on the former power transmission tower frame, does not destroy the structure of former power transmission tower frame, and makes reinforcement elements and former power transmission tower frame become a complete whole, and the wind resistance effect is better; On the other hand, this reinforcement elements is simple in structure, easy for installation, duration weak point, and cost is low, is suitable for large application scope.

Fig. 1 is the structural representation of the utility model power transmission tower frame;
Fig. 2 is the front view of the utility model reinforcing area;
Fig. 3 is the stereogram of the utility model reinforcing area.
The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing:
Extremely shown in Figure 3 like Fig. 1; The utility model power transmission tower frame, it includes 4 main materials 10, many horizontal materials 11 and 12,4 said main materials 10 of many oblique materials and is 90 degree mutually and distributes and form rectangles; Many said horizontal materials 11, many said oblique materials 12 and 4 said main materials 10 are connected to form frame construction through gusset plate and bolt; And form a plurality of nodes 13, and its connected mode has belonged to prior art, and the utility model repeats no more at this.
According to the design specifications of power transmission tower frame, in the above 4-5 section of column foot said horizontal material 11 often is not set, because wind load is to the effect of power transmission tower frame and lead; Bigger side direction shearing and moment of flexure are born in the power transmission tower frame bottom, and the requirement of installation is considered on power transmission tower frame top, and rigidity is general bigger; Like this; The bottom rigidity of power transmission tower frame needs to strengthen, and is as shown in Figure 1, confirms that the rigidity of reinforcing area 100 needs reinforcement.
At said reinforcing area 100 a plurality of reinforcement elements 110 are set, each reinforcement elements 110 includes many and reinforces horizontal material 101 and the many oblique materials 102 of reinforcing.Wherein, the horizontal material 101 of per 4 said reinforcings connects the node 13 formation tabula faces that are on the same plane; The oblique material 102 of per 3 said reinforcings is connected to form firm triangle diagonal brace face, and this diagonal brace face is connected with 12 of said oblique materials, and an angle of this diagonal brace face is connected (as shown in Figure 3) with said node 13.
For further strengthening the rigidity of said reinforcement elements 110; Said reinforcement elements 110 also includes a plurality of cross bars 103; The mid point of adjacent two horizontal materials 101 of said reinforcing connects through said cross bar 103; 4 said cross bars 103 be connected to form one with said tabula face in the rectangle that connects, said tabula face is reinforced.
In this preferred embodiment, the spacing of adjacent two said tabula faces is less than or equal to the width of 5 times of said power transmission tower frames.When reality was built said power transmission tower frame, (for example: section bars such as steel pipe) be connected to form, the spacing of adjacent two said tabula faces was less than or equal to 4 times of raw-material length of each root to said main material 10 for many raw material.
Preferably, the horizontal material of said reinforcing 101, the oblique material 102 of said reinforcing and said cross bar 103 are preferably the section bar consistent with said main material 10 and said oblique material 12, strengthen the globality of said power transmission tower frame.When said reinforcement elements 110 is set; Should utilize existing node 13 as far as possible; Try not to destroy existing form of structure; If the set-up mode of the horizontal material of said reinforcing 101, the oblique material 102 of said reinforcing exists with the structure of existing power transmission tower frame and conflict, should be earlier the horizontal material of said reinforcing 101, the oblique material 102 of said reinforcing be reinforced capable more original horizontal material 11 of dismounting and oblique material 12.After setting said reinforcement elements 110, carry out the structural strength checking computations, confirm the consolidation effect of said power transmission tower frame.
The specific embodiment of the utility model does not limit the protection domain of the utility model with this; Do not violate any replacement and the improvement of being done on the basis of the utility model design, all belonging to the protection domain of the utility model.
