Please refer to fig. 3, which is a structural diagram of a second embodiment of the fastener of precast concrete according to the present invention. Fig. 4 is a structural view of a third embodiment of the fastener of precast concrete of the present invention. These two embodiments differ from the embodiment shown in fig. 1 in the structure of the stop block 12. The structures in fig. 2(b) and 2(d), respectively.
Referring to fig. 5, the main difference of the present embodiment is that a square-shaped receiving cavity 111 is provided on the side of the support 11 according to the practical application. For example, the supporting column 11 may have three sides or four sides with accommodating cavities 111, and in the present embodiment, four sides with accommodating cavities 111 are taken as an exemplary aspect. Of course, the stop block 12 is also provided on both sides of the opening of each receiving cavity 111, and the stop block 12 has the characteristics highlighted in the previous embodiment.
Referring to fig. 6, the main difference of the present embodiment is that a square-shaped receiving cavity 111 is provided on the side of the support 11 according to the practical application. In the present embodiment, a side surface is provided with a receiving cavity 111 as an exemplary aspect. Of course, the stop block 12 is also provided on both sides of the opening of each receiving cavity 111, and the stop block 12 has the characteristics highlighted in the previous embodiment.
Please refer to fig. 7, which is a structural diagram of a first embodiment of a supporting assembly of the present invention. In the present embodiment, the same reference numerals denote the same or similar elements, and the configuration thereof is also the same or similar, and the same or similar parts will not be described again. That is, the supporting column 11 in the previous embodiment is called a concrete pile 11 in the present embodiment, and the fastened member in the previous embodiment is called a protection plate 20 in the present embodiment.
As shown, the supporting member may include a plurality of spaced and parallel concrete piles 11 and a shielding plate 21 connected between two adjacent concrete piles 11. The locking piece is arranged on the upper portion of the concrete pile 11, the two opposite side faces of the upper portion of the concrete pile 11 are both provided with a containing cavity 111 in a recessed mode, the containing cavity is arranged in the height direction, and the two sides of the opening of the containing cavity are provided with stop blocks 12. The fastening part is arranged on the protection plate 21, the two ends of the protection plate 21 are respectively provided with a first combining part 211, the first combining parts 211 are inserted from the top end of the accommodating cavity 111, and the stop block 12 is used for locking the first combining parts 211. The shape of the first coupling portion 211 corresponds to the shape of the receiving cavity 111 and the stopper block 12 after being coupled, so that the first coupling portion 211 is received in the receiving cavity 111 and is locked by the stopper block 12 so as not to be separated from the opening (i.e., the direction of the side) of the receiving cavity 111, thereby effectively connecting the concrete pile 11 and the protection plate 21.
And protective layers are respectively arranged outside the concrete pile 11 and the protective plate 21.
Preferably, the concrete pile 11 and the protection plate 21 are respectively provided with an adjusting hole for adjusting a gap between the concrete pile 11 and the protection plate 21. In this embodiment, the adjusting hole of the concrete pile 11 is a first adjusting hole 112, and the adjusting hole of the protection plate 21 is a second adjusting hole 212.
Incidentally, the concrete pile 11 is preferably not less than C60 in structural strength, and its inner main reinforcement may be prestressed steel bars. The fender panel 21 is preferably constructed at about C30 with internal reinforcement made of three grade steel HRB 400.
It should be noted in particular that, in the appropriate conditions, the internal main reinforcement of the concrete pile 11 may extend up to said stop block 12 (shown in broken lines in fig. 7). For example, when the self weight of the protection plate 21 plus the tensile force due to construction load exceeds the limit of the shearing force that the concrete pile 11 and the stopper piece 12 can bear, it is necessary to extend the inner main reinforcement of the concrete pile 11 to the stopper piece 12. And calculating the limit value of the tolerable shearing force, such as: shear is the concrete shear plus the stirrup shear, which can be expressed as follows:
shear-resistant (0.7 × Ft × b × h0) + (Fyv × Asv × h 0/s).
Preferably, a plurality of vertical steel bars are arranged inside the concrete pile 11 in parallel along the length direction, and the vertical steel bars located outside the two connecting grooves are connected through transverse steel bars. The two transverse reinforcing steel bars which are oppositely arranged and the vertical reinforcing steel bar which is positioned at the inner side are connected through the reinforcing steel bar. The end part of the transverse reinforcing steel bar is positioned at the opening of the connecting groove, and the end part of the transverse reinforcing steel bar is bent into a hook-shaped part.
In addition, at least one positioning hole can be arranged in the accommodating cavity 111 of the concrete pile 11 in the vertical direction according to actual requirements, and the positioning hole is freely arranged according to the plate length of the protection plate 21 to control the protection plate 21 to sink in the connection or construction process. Furthermore, at least one water stopping groove can be reserved on the opposite surface of one or two elements of the concrete pile 11 and the protection plate 21 for arranging an expansion rubber strip, so that the water stopping effect is achieved. For example, the water stopping groove may be disposed on the bottom surface of the accommodating cavity 111 and disposed along the up-down direction.
As described above, the precast concrete connection structure according to the present invention has excellent structural strength after connection by the predetermined structural arrangement of the concrete piles 11 and the guard plates 21.
Please refer to fig. 8, which is a structural diagram of a second embodiment of a supporting assembly of the present invention. In the present embodiment, the same reference numerals denote the same or similar elements, and the configuration thereof is also the same or similar, and the same or similar parts will not be described again.
As shown in the figures, the main difference between the present embodiment and the previous embodiment is that the cross-sectional shape of the stopper block 12 is a sector. Wherein, the cambered surfaces of the two stop blocks 12 are opposite. Correspondingly, the shape of the first combining portion 211 corresponds to the shape of the accommodating cavity 111 after being combined with the stopper 12, so that the first combining portion 211 is also an arc surface at a portion corresponding to the arc surface of the stopper 12.
Therefore, the first coupling portion 211 is received in the receiving cavity 111, and is locked by the stopper block 12 so as not to be separated from the opening (i.e., the direction of the side surface) of the receiving cavity 111, thereby effectively connecting the concrete pile 11 and the guard plate 21.
As described above, the precast concrete connection structure according to the present invention has excellent structural strength after connection by the predetermined structural arrangement of the concrete piles 11 and the guard plates 21.

As shown, the precast concrete connection structure may further include another protection plate 31. Wherein the further shield plate 31 is substantially similar to the concrete pile 11. That is, the other shielding plate 31 has a long bar-shaped structure, and the sectional shape thereof is a quadrangular shape. The main difference is that at least one side surface of the another protection plate 31 is provided with a second combining portion 311, and in the embodiment, the two opposite side surfaces of the another protection plate 31 are provided with the second combining portions 311 as an exemplary aspect, but according to actual application requirements, one side surface, three side surfaces or four side surfaces are provided with the second combining portions 311, so that the limitation should not be made. The shape of the second coupling portion 311 corresponds to the shape of the receiving cavity 111 and the stopper block 12 after being coupled, and the second coupling portion 311 is received in the receiving cavity 111 and is locked by the stopper block 12 so as not to be separated from the opening (i.e., the direction of the side surface) of the receiving cavity 111, thereby effectively connecting the concrete pile 11 and the second concrete pile 31.
Incidentally, the structural strength of the concrete pile 11 and the other shield plate 31 is preferably not less than C60, and the inner main reinforcement thereof may be prestressed steel bars.
Preferably, the concrete pile 11 and the other protection plate 31 are respectively provided with an adjusting hole for adjusting a gap between the concrete pile 11 and the other protection plate 31. In this embodiment, the adjusting hole of the concrete pile 11 is a first adjusting hole 112, and the adjusting hole of the other protection plate 31 is a third adjusting hole 312. The adjusting holes are used for adjusting the distance between the concrete piles and the protection plates, and accumulated errors are reduced.
Incidentally, in the present embodiment, the shape of the stop block 12 may be replaced by a fan shape, and the detailed description thereof is omitted here for brevity.
Therefore, the first coupling portion 311 is received in the receiving cavity 111, and is locked by the stopper block 12 so as not to be separated from the opening (i.e., the direction of the side surface) of the receiving cavity 111, thereby effectively connecting the concrete pile 11 and the guard plate 21.
As shown in fig. 10, the main difference between the present embodiment and the previous embodiment is described, and under the requirement of practical application, the receiving cavity 111 and the stop block 12 may be disposed on the protection plate 11, and the joint portion may be disposed on the concrete pile 12, which may also achieve the intended purpose of the present invention.
In summary, the supporting member of the present invention is configured by the predetermined structure of the concrete pile 11 and the other protective plate 31, so as to have good structural strength after connection.
The precast concrete support assembly is additionally provided with the neck necking with the small outside and the large inside of the accommodating cavity, so that the connection between the two elements can be prevented from being separated, and the integrity of the connection is ensured. And the construction sequence of the material adopts the construction sequence that the connectors are sleeved one by one, namely, the connectors are sequentially driven, so that the construction forming effect is controlled. In addition, at least 1 transverse water stopping groove is reserved on the side face of one element to provide an expansion rubber strip, and a water stopping effect is achieved. Adjusting holes are reserved in the top section of the pile and the plate to ensure construction linearity and perpendicularity. The piles and the plate neck necking tenons are internally provided with stirrups or main reinforcements or both (the stressed reinforcements can be reinforcing steel bars, steel stranded wires, glass fiber rods, polymer synthetic rods and the like), and the dead weights and external forces of the connecting columns and the plates generate tensile forces to the piles and the plate neck necking tenons, so that the structures of the piles and the plate neck necking tenons are damaged. The multi-angle connection steering mechanism is suitable for multi-angle connection and connection steering at any angle. The stability of the structure can be improved by increasing the combined connections in the direction of the force. The engineering linearity is controlled by adjusting the angle of the male tenon. The method can avoid on-site crown beam operation, reduce environmental pollution, reduce economic cost, improve construction efficiency and ensure quick, efficient and environment-friendly construction.
