Referring to fig. 3, a second embodiment of a locking element for precast concrete according to the present invention is shown in block diagram. Fig. 4 is a structural view of a third embodiment of the locking member for precast concrete according to 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 the side surface of the pillar 11 is provided with a receiving cavity 111 with a shape of a Chinese character 'kou' depending on the practical application. For example, the supporting column 11 may have three sides or four sides with the accommodating cavity 111, and in this embodiment, four sides with the accommodating cavity 111 are taken as an exemplary aspect. Naturally, the stop blocks 12 are also provided on both sides of the opening of each housing cavity 111, and the stop blocks 12 have the characteristics highlighted in the previous embodiment.
Referring to fig. 6, the main difference of the present embodiment is that the side surface of the pillar 11 is provided with a receiving cavity 111 with a shape of a Chinese character 'kou' depending on the practical application. In this embodiment, a housing 111 is provided on one side as an exemplary embodiment. Naturally, the stop blocks 12 are also provided on both sides of the opening of each housing cavity 111, and the stop blocks 12 have the characteristics highlighted in the previous embodiment.
Please refer to fig. 7, which is a block diagram of a first embodiment of the support assembly of the present invention. In the present embodiment, elements with the same reference numerals denote the same or similar elements, and the configuration thereof is the same or similar, and the same or similar parts will not be described herein. That is, the stay 11 in the foregoing embodiment is referred to as a concrete pile 11 in this embodiment, and the locked member in the foregoing embodiment is referred to as a shielding plate 20 in this embodiment.
As shown, the support assembly may include a number of spaced and parallel arranged concrete piles 11 and a guard plate 21 connected between adjacent two concrete piles 11. The locking pieces are arranged on the upper portion of the concrete pile 11, accommodating cavities 111 arranged in the height direction are concavely formed in two opposite side faces of the upper portion of the concrete pile 11, and stop blocks 12 are arranged on two sides of an opening of each accommodating cavity. The locked piece is disposed on the protection plate 21, both ends of the protection plate 21 are provided with first combining parts 211, the first combining parts 211 are inserted from the top end of the accommodating cavity 111, and the stop blocks 12 lock the first combining parts 211. The shape of the first coupling portion 211 corresponds to the shape of the receiving cavity 111 after being coupled with the stop block 12, so that the first coupling portion 211 is received in the receiving cavity 111 and is blocked by the stop 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 protection plate 21.
The concrete piles 11 and the outside of the protection plate 21 are respectively provided with protection layers.
Preferably, the concrete pile 11 and the guard plate 21 are respectively provided with adjusting holes for adjusting a gap between the concrete pile 11 and the guard 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 shielding plate 21 is a second adjusting hole 212.
Incidentally, the structural strength of the concrete pile 11 is preferably not less than C60, and the internal main tendons thereof may be prestressed steel bars. The structural strength of the protection plate 21 is preferably about C30, and the internal reinforcing bars thereof may be three-stage steel HRB400.
It should be noted in particular that, under appropriate conditions, the internal main rib of the concrete pile 11 may extend up to said stop block 12 (as indicated by the broken line in fig. 7). For example, when the tensile force generated by the self weight of the protection plate 21 plus the construction load exceeds the limit value of the shearing force that the concrete pile 11 and the stopper 12 can withstand, it is necessary to extend the internal main rib of the concrete pile 11 to the stopper 12. And the calculation of the limit of the shear force that can be tolerated, for example: shear is the shear of concrete plus stirrup, which can be expressed as follows:
shear = (0.7×ft×b×h0) + (Fyv ×asv×h0/s).
Preferably, a plurality of vertical steel bars are arranged in parallel in the length direction inside the concrete pile 11, and the plurality of vertical steel bars positioned outside the two connecting grooves are connected through transverse steel bars. Wherein, two transverse steel bars that set up relatively and be located between the vertical steel bar of inboard are connected through the strengthening rib. The end parts of the transverse steel bars are positioned at the openings of the connecting grooves, and the end parts of the transverse steel bars are bent into hook-shaped parts.
In addition, at least one positioning hole can be provided in the receiving cavity 111 of the concrete pile 11 in the up-down direction according to the actual requirement, and the positioning hole is freely provided according to the plate length of the protection plate 21, so as to control the protection plate 21 to sink during the connection or construction process. Furthermore, at least one water stop groove can be reserved on the opposite surface of one or both elements of the concrete pile 11 and the protection plate 21 for arranging an expansion adhesive tape, so as to achieve a water stop effect. For example, the water stopping groove may be disposed at the bottom surface of the accommodating cavity 111 and disposed along the up-down direction.
In summary, the prefabricated concrete connecting structure of the present invention has good structural strength after connection by the predetermined structural arrangement of the concrete piles 11 and the protection plates 21.
Please refer to fig. 8, which is a block diagram of a second embodiment of the support assembly of the present invention. In the present embodiment, elements with the same reference numerals denote the same or similar elements, and the configuration thereof is the same or similar, and the same or similar parts will not be described herein.
As shown in the drawing, the present embodiment is mainly different from the previous embodiment in that the cross-sectional shape of the stopper 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 is opposite to the shape of the combined accommodating cavity 111 and the stop block 12, so that the portion of the first combining portion 211 corresponding to the cambered surface of the stop block 12 is also a cambered surface.
Therefore, the first coupling portion 211 is accommodated in the accommodating chamber 111, and is locked by the stopper 12 so as not to be separated from the opening (i.e., the direction of the side surface) of the accommodating chamber 111, thereby effectively coupling the concrete pile 11 and the shielding plate 21.
In summary, the prefabricated concrete connecting structure of the present invention has good structural strength after connection by the predetermined structural arrangement of the concrete piles 11 and the protection plates 21.
Please refer to fig. 9, which is a block diagram of a third embodiment of the support assembly of the present invention. In the present embodiment, elements with the same reference numerals denote the same or similar elements, and the configuration thereof is the same or similar, and the same or similar parts will not be described herein.
As shown, the connection structure of the precast concrete may further include another shielding plate 31. Wherein the further shield 31 is substantially similar to the concrete pile 11. That is, the other guard plate 31 has a long strip structure, and has a quadrangular cross section. The main difference is that at least one side of the other protection plate 31 is provided with a second connecting portion 311, and in this embodiment, two opposite sides of the other protection plate 31 are provided with second connecting portions 311 as an exemplary aspect, but the actual application requirement can be one side, three sides or four sides provided with second connecting portions 311, so the invention should not be limited thereto. The shape of the second coupling portion 311 is a shape of the receiving cavity 111 and the stop block 12 after being coupled, and the second coupling portion 311 is received in the receiving cavity 111 and is locked by the stop 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 guard plate 31 is preferably not less than C60, and the internal main reinforcement thereof may be a prestressed steel bar.
Preferably, the concrete pile 11 and the other guard plate 31 are respectively provided with adjusting holes for adjusting a gap between the concrete pile 11 and the other guard plate 31. In the present embodiment, the adjustment hole of the concrete pile 11 is the first adjustment hole 112, and the adjustment hole of the other protection plate 31 is the third adjustment 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 will not be repeated here.
Therefore, the first coupling portion 311 is accommodated in the accommodating chamber 111, and is locked by the stopper 12 so as not to be separated from the opening (i.e., the direction of the side surface) of the accommodating chamber 111, thereby effectively coupling the concrete pile 11 and the shielding plate 21.
As shown in fig. 10, the main difference between the present embodiment and the previous embodiment is that the accommodating 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 achieve the objective of the present invention.
In summary, the support assembly of the present invention has good structural strength after connection by the predetermined structural arrangement of the concrete pile 11 and the other shield plate 31.
According to the prefabricated concrete support assembly, the small outside and large inside neck shrinkage opening of the accommodating cavity is newly added, so that connection and disconnection between two elements can be prevented, and the integrity of connection is ensured. And the construction sequence of the material adopts the construction sequence of the connectors one by one, namely sequential beating, so as to control the construction molding effect. In addition, at least 1 transverse water stopping groove is reserved on the side face of one element for arranging the expansion adhesive tape, so that a water stopping effect is achieved. The piles and the plates are reserved with adjusting holes on the top section so as to ensure the construction linearity and verticality. Stirrups or main reinforcements or both (the stressed reinforcements can be steel bars, steel strands, glass fiber rods, polymer composite rods and the like) are arranged in the necking tenons of the piles and the plates, and the connecting columns, the dead weights of the plates and external forces generate pulling force on the piles and the plates, so that the structure of the piles and the plates is damaged. Is suitable for multi-angle connection and connection steering at any angle. The stability of the structure can be improved by adding the combined connection of the stress directions. 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.
While the present invention has been described in detail through the foregoing description of the preferred embodiment, it should be understood that the foregoing description is not to be considered as limiting the invention. Many modifications and substitutions of the present invention will become apparent to those of ordinary skill in the art upon reading the foregoing. Accordingly, the scope of the invention should be limited only by the attached claims.
