[0032] A pile foundation building enclosure device, such as Figure 1 and Figure 2 As shown, including:

[0033] A first guard plate 10 and a second guard plate 11 used in conjunction with each other, the first guard plate 10 and the second guard plate 11 are hinged to form a closed ring;

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the first locking structure is arranged at the ends of the first guard plate 10 and the second guard plate 11 for limiting the first guard plate 10 or the second guard plate 11 stacked up and down, and the first locking structure includes a sinking groove 14 and a limiting convex rib 15. The ends of the same side of the first guard plate 10 and the second guard plate 11 are both provided with the same sinking groove 14, and the other ends of the first guard plate 10 and the second guard plate 11 are both fixedly provided with the same limiting convex rib 15, and the limiting convex rib 15 can be stuck in the sinking groove 14 to limit the first guard plate 10 and the second guard plate 11 hinged to each other and maintain a closed state; the first guard plate 10 and the second guard plate 11 are both arc plate structures, and the top and bottom of the first guard plate 10 are provided with An integrally formed annular rib, the top and bottom of the second guard plate 11 are provided with the same rib, the sinking groove 14 forms a half annular notch, the sinking groove 14 is provided on the upper end surface of the first guard plate 10, the sinking groove 14 at the top of the second guard plate 11 and the sinking groove 14 at the top of the first guard plate 10 jointly form a closed annular notch, the limiting rib 15 is provided at the bottom of the first guard plate 10, the limiting rib 15 is a half-circular ring structure, the limiting rib 15 is integrally formed with the first guard plate 10, the limiting rib 15 at the bottom of the second guard plate 11 and the limiting rib 15 at the bottom of the first guard plate 10 jointly form a closed circular ring, and the two limiting ribs 15 form a community adapted to the annular notch;

[0035] In the present solution, the first guard plate 10 and the second guard plate 11 are hinged to form a circular ring structure to wrap the steel bars, so as to achieve enclosure during the pouring process. Obviously, the height of concrete poured by a group of first guard plates 10 and second guard plates 11 to form a tubular structure is limited. Therefore, multiple groups of first guard plates 10 and second guard plates 11 are required to be stacked vertically until a preset height is reached. When another group of first guard plates 10 and second guard plates 11 are stacked, the limiting rib 15 at the bottom of the upper first guard plate 10 falls into the sinking groove 14 of the lower first guard plate 10. Similarly, the limiting rib 15 at the bottom of the upper second guard plate 11 falls into the sinking groove 14 of the lower second guard plate 11. Since the limiting rib 15 is a half ring, when the limiting rib 15 is placed in the sinking groove 14, the connection between the two limiting ribs 15 needs to be maintained. The seam position is staggered with the seam position of the first guard plate 10 and the second guard plate 11, and then the limiting convex rib 15 falls into the sinking groove 14, so that the multiple first guard plates 10 and second guard plates 11 stacked up and down can be self-locked, without the need to tighten with bolts and nuts, and the installation is more convenient. When the first guard plate 10 and the second guard plate 11 are hinged and then the first guard plate 10 and the second guard plate 11 surround the steel bars, it can be ensured that the ends of the first guard plate 10 and the second guard plate 11 are flush and will not be misplaced, which is convenient for subsequent stacking. It should be noted that during the pouring process, the first guard plate 10 and the second guard plate 11 need to be supported. The stacked first guard plates 10 and the second guard plates 11 can be supported by metal scaffolding to prevent tilting and collapse during the pouring process. The scaffolding is an existing well-known technology and will not be described here.

[0036] like Figure 2 and Figure 4 As shown, the outer circumferential surface of the first guard plate 10 is fixedly connected to the ear plate 12, and the outer wall surface of the second guard plate 11 is fixedly connected to the rotating block 13. Axial holes are opened through the walls of the rotating block 13 and the ear plate 12, and a pin is rotatably connected in the axial hole. Through the rotational connection between the ear plate 12 and the rotating block 13, the first guard plate 10 and the second guard plate 11 can be flexibly opened and closed, which is convenient for assembly and disassembly. Compared with the prior art, this solution is more convenient for actual construction, reduces the number of scattered parts after disassembly, and is convenient for storage and transportation.

[0037] By hingedly connecting the first guard plate 10 and the second guard plate 11 and cooperating with the limiting rib 15 to be inserted into the sunken groove 14 for self-locking, the use of bolts and nuts can be reduced, the efficiency of disassembly and assembly can be improved, and the damage of the bolts and nuts caused by repeated disassembly and assembly, which makes them difficult to use, can be reduced. The gravity of the first guard plate 10 and the second guard plate 11 makes the limiting rib 15 firmly stuck in the sunken groove 14, which can provide both horizontal and vertical limitations, reducing the probability of bolts being broken or deformed due to excessive shear force and becoming difficult to remove.

[0038] like Figure 1 and Figure 6 As shown, the second locking structure is detachably arranged in the sinking groove 14 and is used to lock the top first guard plate 10 and the second guard plate 11. The second locking structure includes a first anti-slipping member 20 and a second anti-slipping member 21. The first anti-slipping member 20 and the second anti-slipping member 21 are clamped and form a closed ring. The first anti-slipping member 20 and the second anti-slipping member 21 are clamped in the sinking groove 14 to limit the movement of the first guard plate 10 and the second guard plate 11. The first anti-slipping member 20 and the second anti-slipping member 21 together form a closed ring structure. 20 and the second anti-slip component 21 are adapted to the sinking groove 14, and the snap-in protrusion 22 is integrally formed with the first anti-slip component 20. By setting the first anti-slip component 20 and the second anti-slip component 21, the second anti-slip component 21 and the second anti-slip component 21 fall into the sinking groove 14, so that the top first guard plate 10 and the second guard plate 11 can maintain a closed state without rotating and separating. The splicing position of the first anti-slip component 20 and the second anti-slip component 21 needs to be staggered with the seam position of the first guard plate 10 and the second guard plate 11 to ensure the tightening effect.

[0039] like Figure 6As shown, the second locking structure also includes a clamping protrusion 22. The clamping protrusion 22 is fixedly arranged at the end of the first anti-slip component 20. The first anti-slip component 20 is clamped and fixed to the second anti-slip component 21 through the clamping protrusion 22. The clamping protrusion 22 forms a block with a dovetail shape in horizontal cross section. The end face of the second anti-slip component 21 is provided with a notch adapted for the clamping protrusion 22. The clamping protrusion 22 is clamped into the notch. By setting the clamping protrusion 22 and utilizing the clamping protrusion 22 to be clamped into the notch, the first anti-slip component 20 and the second anti-slip component 21 form an annular structure, and the first anti-slip component 20 and the second anti-slip component 21 can better provide circumferential limitation, and the first guard plate 10 and the second guard plate 11 can stably maintain a closed state.

[0040] like Figure 6 As shown, the second locking structure also includes a side groove 23. The circumferential surfaces of the first anti-slip component 20 and the second anti-slip component 21 are both provided with the same side groove 23 for separating the first anti-slip component 20 and the second anti-slip component 21 from the sinking groove 14. By setting the side groove 23, specifically, the side groove 23 is a rectangular groove, and a crowbar or a flat tool can be inserted into the side groove 23 to pry out the first anti-slip component 20 or the second anti-slip component 21, thereby facilitating the removal of the first anti-slip component 20 and the second anti-slip component 21.

[0041] The working principle of the utility model is as follows: when another set of first guard plates 10 and second guard plates 11 are stacked, the limiting rib 15 at the bottom of the upper first guard plate 10 falls into the sinking groove 14 of the lower first guard plate 10, and similarly, the limiting rib 15 at the bottom of the upper second guard plate 11 falls into the sinking groove 14 of the lower second guard plate 11. Since the limiting rib 15 is a half ring, when the limiting rib 15 is placed in the sinking groove 14, it is necessary to keep the joint position of the two limiting ribs 15 aligned with the first guard plate 1 The joint positions of the first and second guard plates 10 and 11 are staggered, and the limiting convex ribs 15 fall into the sinking groove 14, so that the multiple first guard plates 10 and the second guard plates 11 stacked up and down can be self-locked, and the second anti-slipping member 21 and the second anti-slipping member 21 fall into the sinking groove 14 of the top first guard plate 10 and the second guard plate 11, so that the top first guard plate 10 and the second guard plate 11 can maintain a closed state without rotating and separating, and pouring into the cavity of the multiple first guard plates 10 and the second guard plates 11 can be done;

[0042] During the pouring process, the first guard plate 10 and the second guard plate 11 need to be supported. A metal scaffolding can be used to support the stacked first guard plate 10 and the second guard plate 11 to prevent them from tilting and collapsing during the pouring process. The scaffolding is an existing well-known technology and will not be described in detail here.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
