Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0028] Please refer to Figure 1 and Figure 2 , Figure 1 A structural schematic diagram of a prefabricated component provided by a specific embodiment of the present application is shown in the figure. Figure 2 A structural schematic diagram of a prefabricated component when inserted into a soil layer is shown in the figure.
[0029] The prefabricated component 100 provided by the embodiment of the present application includes a T-shaped pile, an ecological pile, etc., wherein the T-shaped pile refers to a pile body structure with a T-shaped cross section, such as Figure 1The prefabricated component 100 shown in the drawings has a T-shaped cross section, and can be made of concrete and steel bars. For example, a steel cage can be prefabricated, placed in a mold, and then concrete is poured to embed the steel cage in the concrete, thereby improving the structural strength of the prefabricated component 100. The prefabricated component 100 includes a wing plate 10 and a web plate 20, which are preferably integrally formed. The wing plate 10 has a first surface 11 and a second surface 12 on one side close to the web plate 20. The first surface 11 and the second surface 12 are respectively located on both sides of the web plate 20. The web plate 20 has a first side surface 21 and a second side surface 22. The first surface 11 and the first side surface 21 intersect, and the second surface 12 and the second side surface 22 intersect. The included angle between the first surface 11 and the first side surface 21 is an acute angle, and / or the included angle between the second surface 12 and the second side surface 22 is an acute angle. That is, there are three angle relationships: (1) the included angle between the first surface 11 and the first side surface 21 is an acute angle, and the included angle between the second surface 12 and the second side surface 22 can be selected as needed, such as an acute angle, a right angle, or an obtuse angle; (2) the included angle between the second surface 12 and the second side surface 22 is an acute angle, and the included angle between the first surface 11 and the first side surface 21 can be selected as needed, such as an acute angle, a right angle, or an obtuse angle; (3) the included angle between the first surface 11 and the first side surface 21 is an acute angle, and the included angle between the second surface 12 and the second side surface 22 is an acute angle, that is, at least one of the first surface 11 and the second surface 12 of the wing plate 10 of the prefabricated component 100 has a concave structure. Figure 1 As shown in the drawings, the left side above the wing plate 10 is the first surface 11, the right side above the wing plate 10 is the second surface 12, the left side of the web plate 20 is the first side surface 21, and the right side of the web plate 20 is the second side surface 22.
[0030] In the above embodiment, since the side of the wing plate 10 of the prefabricated component 100 close to the web plate 20 is provided with a concave structure, the contact area between the prefabricated component 100 and the soil layer 200 can be effectively increased, thereby ensuring the stability of the prefabricated component 100 after construction. In addition, since the first surface 11 and / or the second surface 12 of the wing plate 10 are inclined relative to the web plate 20, for example Figure 1 As shown in the drawings, the X direction is the width direction of the wing plate 10, the Y direction is perpendicular to the X direction, the first surface 11 and the second surface 12 of the wing plate 10 have an included angle with the X direction, and the first side surface 21 and the second side surface 22 of the web plate 20 extend along the Y direction. When the prefabricated component 100 is placed in the soil layer 200 by the pile driver, the corners of the wing plate 10 and the web plate 20 will be filled with the soil layer 200. Since the corners are concave structures, the soil layer 200 can be effectively embedded in the corners, thereby improving the stability of the prefabricated component 100 after construction. As shown in the drawings, Figure 2As shown, since the first surface and the second surface of the wing plate are inclined surfaces, the soil layer 200 on the first inclined surface is blocked in the F1 direction, and the soil layer 200 on the second inclined surface is blocked in the F2 direction, so that the soil layer 200 can be effectively prevented from being separated outward from the corner of the prefabricated component 100, and the combination effect of the prefabricated component 100 and the soil layer 200 is improved, so that the stability of the prefabricated component 100 after being placed in the soil layer 200 can be ensured. However, the first surface 11 of the existing prefabricated component 100 is usually parallel to the X direction, so that the soil layer 200 at the corner is easily separated outward along the X direction, so that the stability of the prefabricated component 100 after construction is difficult to ensure. Moreover, compared with the existing prefabricated component 100, the material can be effectively saved, and the purpose of reducing manufacturing cost is realized.
[0031] In some embodiments, the first side surface 21 and the first surface 11 are circularly arc transitioned, and the second side surface 22 and the first surface 11 are circularly arc transitioned, as shown in Figure 1 As shown, the junction position of the lower part of the first side surface 21 of the web plate 20 and the right part of the first surface 11 of the wing plate 10 is a circular arc transition structure, and the junction position of the lower part of the second side surface 22 of the web plate 20 and the left part of the first surface 11 of the wing plate 10 is a circular arc transition structure. Through the circular arc transition structure, stress concentration can be reduced, and the structural stability and bearing capacity of the prefabricated component 100 can be ensured. In addition, through the circular arc transition, the mold can be easily demolded during manufacturing, and the manufacturing yield can be improved.
[0032] In some embodiments, the side of the wing plate 10 away from the web plate 20 has a third surface 13, as shown in Figure 1 As shown, the upper part of the wing plate 10 is provided with the web plate 20, the lower surface of the wing plate 10 is a third surface 13, the first side surface 21 and the second side surface 22 are perpendicular to the third surface 13, and the first surface 11 and the second surface 12 of the wing plate 10 respectively form an angle with the third surface 13 of the wing plate 10. The prefabricated component 100 of this structure can be easily demolded during manufacturing. Of course, for those who do not need demolding, the first side surface 21 and the second side surface 22 of the web plate 20 can be inclined to the third surface 13 of the wing plate 10, for example Figure 1 As shown, the width of the web plate 20 gradually decreases along the Y direction from top to bottom, at this time, the first surface 11 and the second surface 12 of the wing plate 10 can be parallel to the third surface 13, or can be inclined to the third surface 13. For ecological piles, water permeable holes can be provided on the basis of T piles to form ecological piles, for example, water permeable holes can be provided on the first surface 11, and / or the second surface 12, and / or the third surface 13 of the T pile, and further, through holes can be provided in the web plate 20 and / or the wing plate 10 of the T pile, the through holes extending along the length direction of the T pile, wherein the water permeable holes can be communicated with the through holes.
[0033] In some embodiments, the wing plate 10 has a first end 14 and a second end 16, as shown in Figure 1 The left end of the wing plate 10 is the first end 14, and the right end of the wing plate 10 is the second end 16, wherein the first end 14 is close to the first surface 11, the first end 14 is provided with a clamping protrusion 15, and the second end 16 is provided with a clamping groove 17, and two adjacent prefabricated components 100 are connected to each other through the clamping protrusion 15 and the clamping groove 17. In a specific use process, a plurality of prefabricated components 100 need to be applied, for example, connected in sequence to form a larger plate structure, wherein through the clamping protrusion 15 and the clamping groove 17, the connection stability of the prefabricated components 100 can be improved to prevent the prefabricated components 100 from being separated.
[0034] In some embodiments, as shown in Figure 1 The clamping protrusion 15 is a dovetail protrusion, and the clamping groove 17 is a dovetail groove. When assembling, the clamping protrusion 15 of one prefabricated component 100 can be pushed into the clamping groove 17 of another prefabricated component 100 along the groove length direction of the clamping groove 17, and after the two are connected, positioning and fixing in the X direction and the Y direction can be realized.
[0035] In some embodiments, the clamping protrusion 15 is a T-shaped protrusion, and the clamping groove 17 is a T-shaped groove, wherein the corners of the T-shaped protrusion and the T-shaped groove can be selected as circular arc transitions to reduce stress concentration. After the clamping of the T-shaped protrusion and the T-shaped groove of two adjacent prefabricated components 100, positioning and fixing in the X direction and the Y direction can be realized.
[0036] In some embodiments, the clamping protrusion 15 is an arc-shaped protrusion, and the clamping groove 17 is an arc-shaped groove, and the central angles of the arc-shaped protrusion and the arc-shaped groove are both greater than 180°. The arc-shaped protrusion and the arc-shaped groove can realize the hinged relationship of the two adjacent prefabricated components 100, that is, when the two adjacent prefabricated components 100 are connected through the arc-shaped protrusion and the arc-shaped groove, the relative angle of the two prefabricated components 100 can be adjusted to adapt to the corresponding construction environment requirements.
[0037] In some embodiments, as shown in Figure 1As shown, the minimum distance between the third surface 13 and the first surface 11 is smaller than the minimum distance between the third surface 13 and the second surface 12, and the maximum distance between the third surface 13 and the first surface 11 is smaller than the maximum distance between the third surface 13 and the second surface 12. Since the second end 16 of the wing plate 10 is provided with the clamping groove 17, in order to ensure the structural strength of the clamping groove 17 of the wing plate 10, the thickness of the part of the wing plate 10 on the right side of the web plate 20 can be increased, that is, the thickness of the right part of the wing plate 10 in the Y direction is increased. Preferably, the maximum distance between the third surface 13 and the first surface 11 is not greater than the minimum distance between the third surface 13 and the second surface 12, so as to reduce the material use of the prefabricated component 100 while ensuring the bearing capacity of the prefabricated component 100. The distance between the outer end surface of the first end 14 and the first side surface 21 is equal to the distance between the outer end surface of the second end 16 and the second side surface 22, that is, the width of the part of the wing plate 10 on the left side of the web plate 20 in the X direction is equal to the width of the part of the wing plate 10 on the right side of the web plate 20 in the X direction.
