Description of the embodiments
The features of the utility model and other related features are described in further detail below by way of example in conjunction with the following figures to facilitate understanding by those skilled in the art:
as shown in fig. 1-4, the labels 1-9 are shown as: prefabricated section 1, connection lug 2, connection recess 3, diaphragm 4, cross manhole 5, connection pedestal 6, tower section of thick bamboo base 7, inboard connection lug 8, sharp prestressing tendons 9.
Examples: as shown in fig. 1 to 4, the connection structure for the wind power precast concrete tower in the present embodiment is used for realizing the precast assembly construction of the wind power precast concrete tower.
Specifically, as shown in fig. 1, the wind power precast concrete tower barrel in the embodiment is a segmental precast assembly structure and adopts a variable cross-section design; the variable cross-section arrangement means that the cross-section size of each prefabricated segment 1 is gradually reduced from bottom to top along the height direction of the concrete tower, so as to form the concrete tower with the shape of 'small top and big bottom' shown in fig. 1. In some cases, the concrete sleeve is vertically divided into a plurality of precast segments 1 according to 8-15m, and the middle precast segments adopt standard sizes except the height of the top precast segment and the height of the bottom precast segment, so that the application range of the precast segments can be improved, and the design of the concrete tower is also facilitated.
As shown in fig. 1, a connection lug 2 is arranged on the inner side of the prefabricated section, the connection lug 2 between the upper and lower adjacent prefabricated sections 1 is spliced and is connected by arranging a vertical steel bar grouting anchor (a part of the anchor steel bars can be provided with a temporary bolt anchor), so that the upper and lower adjacent prefabricated sections 1 can be connected and fixed to form an integral structure. Simultaneously, the outer sides of the prefabricated sections 1 are welded and connected through the vertical steel bars in the connecting grooves 3, and UHPC connection is poured, so that effective and stable connection can be formed between the inner side and the outer side of each upper prefabricated section 1 and the outer side of each lower prefabricated section 1.
In this embodiment, in order to ensure close contact between the prefabricated segments 1, and further ensure tightness, a mortar cushion layer may be provided at the joint positions of the prefabricated segments 1.
As shown in fig. 1, the prefabricated segments at the bottom are connected to the tower foundation 7 via connection pedestals 6.
A diaphragm plate 4 is arranged at the top of the prefabricated tower 1, and the diaphragm plate 4 plays a role in separating on one hand and plays a role in reinforcing structural strength and stability on the other hand. In order to facilitate the maintenance of the tower, a manhole 5 is reserved in the middle of the diaphragm 4.
The embodiment is implemented in specific manner: as shown in fig. 2 or 3, when the hanging weight of the precast segments 1 is limited, each precast segment 1 can be further precast by blocks in the horizontal direction, and is formed by splicing two semicircular or four 1/4 circular precast concrete members with connecting lugs 8 through tensioning linear prestressed tendons 9.
Although the foregoing embodiments have been described in some detail with reference to the accompanying drawings, it will be appreciated by those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the utility model as defined in the appended claims, and thus are not repeated herein.
