Abstract
Description
Technical Field
[0001] This utility model relates to a connection device for precast pile foundation of power transmission tower. Background Technology
[0002] In actual engineering, the tower feet and foundations of power transmission line towers are generally connected by anchor bolts. In order to ensure the strength of the connection and the durability of the components, the bolt spacing and the outer concrete protective layer must meet certain size requirements. This requires that the concrete cast-in-place piles for embedding anchor bolts be large enough to meet the structural requirements. Foundations designed in this way often have redundant bearing capacity, and the construction period of cast-in-place piles is long and the amount of work is large, which does not meet the requirements of economy.
[0003] Precast concrete piles are widely used in various engineering structures due to their advantages such as high bearing capacity, good durability, simple construction process, and low cost. However, due to the hollow structure of cast-in-place concrete piles, it is not conducive to the installation of anchor bolts. Therefore, the foundations of power transmission line towers generally still use traditional cast-in-place concrete piles, rather than precast concrete piles which are more economical and safer. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a connection device for precast pile foundation of power transmission towers, which addresses the shortcomings of the existing technology.
[0005] The specific technical solution of this utility model is as follows:
[0006] A precast pile foundation connection device for a power transmission tower includes a precast pile, a base plate connected to the top of the precast pile, and the base plate connected to the tower foot through a connection device.
[0007] The connecting device includes support steel plates welded together in a cross shape, reinforcing steel plates welded on both sides of the support steel plates, and a top plate connected to the upper part of the support steel plates. The top plate is connected to the tower foot of the power transmission tower.
[0008] The precast piles are made of precast concrete, and an end plate is welded to the top of the pile end. The bottom plate is welded to the upper reinforcing steel plate and supporting steel plate to form a whole. The lower part of the bottom plate is connected to the end plate at the top of the precast pile by welding.
[0009] The beneficial effects of this utility model are as follows: This utility model uses a connecting device to tightly connect the tower foot of the power transmission tower and the precast pile together, which meets the structural safety requirements. The use of welding and bolt connection not only ensures the strength of the structure, but also facilitates construction, saves time and money, and has good economic benefits.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0015] like Figure 1 , Figure 2 , Figure 3 As shown, a precast pile foundation connection device for a power transmission tower includes a precast pile 1, a base plate 2 connected to the top of the precast pile 1, and the base plate 2 connected to the tower foot 4 through a connection device 3.
[0016] The connecting device 3 includes a support steel plate 31 welded together in a cross shape, a reinforcing steel plate 32 welded on both sides of the support steel plate 31, and a top plate 33 connected to the upper part of the support steel plate 31. The top plate 33 is connected to the tower foot 4 of the power transmission tower.
[0017] Precast pile 1 is a precast concrete pile, and an end plate 11 is welded to the top of the pile end. The bottom plate 2 is welded to the upper reinforcing steel plate 32 and supporting steel plate 31 to form a whole. The lower part of the bottom plate 2 is connected to the end plate 11 at the top of the precast pile 1 by perimeter welding. Figure 3 As shown. Anchor bolts are not arranged in precast pile 1. Under the condition of meeting the bearing capacity, piles with smaller diameters can be appropriately selected to save costs. The connection method of the node is welding and bolt connection, which makes on-site construction less difficult and faster.
[0018] In summary, the connecting device 3 tightly connects the tower foot of the power transmission tower and the precast pile 1 together, meeting the structural safety requirements. The use of welding and bolting connections ensures the structural strength, facilitates construction, saves time and money, and has good economic efficiency.
