Description

Technical Field

[0001] This invention belongs to the field of concrete wall panel technology, specifically a concrete wall panel installation structure and its construction method. Background Technology

[0002] In areas where the foundation has lower reinforcing bars, pads are placed on the foundation according to pre-planned support points. These pads can be elastic pads or solid wood boards. The wall panel is then hoisted into the air, positioned above the lower reinforcing bars on the foundation. The position of the wall panel is gradually corrected during its descent with manual assistance. Movement stops when the upper cylinder on the wall panel is close to the lower reinforcing bars on the foundation. At this point, workers typically use a mirror to observe whether the lower reinforcing bars and the upper cylinder are aligned. If aligned, the wall panel is lowered and placed above the pads, which then support the panel. If misaligned, the position of the wall panel is manually adjusted, or the lower reinforcing bars are corrected. This process completes the installation of the lower reinforcing bars and the upper cylinder during the wall panel installation.

[0003] However, the above operation requires the placement of shims and repeated observations by staff to ensure that the lower steel bar and the upper cylinder are aligned. If they are not aligned, the lower steel bar needs to be corrected so that it is directly below the upper cylinder for easy subsequent connection. Therefore, the operation is quite complicated and a simpler method is needed. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a concrete wall panel installation structure and its construction method, which effectively solves the problem that the wall panel installation process requires the placement of pads and the repeated observation by workers to check whether the reinforcing bars are aligned with the upper cylinder, which is a rather cumbersome operation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a concrete wall panel installation structure, comprising a foundation with lower reinforcing bars and a wall panel with an upper cylinder, wherein a gap is reserved between the foundation and the wall panel, and a guide unit is provided inside the upper cylinder, the guide unit comprising an upper cover plate and a conical cylinder, a clamping rod and an elastic rope being fixed on the upper cover plate, the conical cylinder comprising a plurality of connecting plates and elastic pads arranged at intervals and connected to each other, a groove being provided on the connecting plate, a movable frame being hinged in the groove, and a torsion spring being provided at the hinge point between the movable frame and the groove, an upper clamping groove being provided on the connecting plate, a lower clamping groove being provided on the movable frame, and the upper cover plate being fixed to the connecting plate by the elastic rope;

[0006] Normally, the movable frame is stored in the slot, and the locking rod passes through the upper locking slot and engages with the lower locking slot. When in use, the locking rod disengages from the upper and lower locking slots, and the movable frame moves out of the slot. Its bottom end abuts against the lower reinforcing bar, and its top end abuts against the wall panel.

[0007] Preferably, the wall panel is fixed with upper reinforcing bars, and an edge seal is formed between the foundation and the wall panel, with a gap formed between the foundation, the wall panel and the edge seal.

[0008] Preferably, the wall panel has a lower grouting hole, an upper grouting outlet hole, and a grout return hole. The lower grouting hole is connected to the bottom of the upper cylinder, the upper grouting outlet hole is connected to the top of the upper cylinder, and the corresponding two upper cylinders are connected through the grout return hole.

[0009] Preferably, the upper cover plate is circular in shape and has through holes.

[0010] Preferably, the connecting plate is trapezoidal in shape, the elastic pad is strip-shaped, and the elastic pad is made of silicone material.

[0011] Preferably, the locking rod, the upper locking slot, and the lower locking slot are arranged in a one-to-one correspondence, and under normal conditions, the centers of the three are located on the same axis.

[0012] Preferably, there are at least three elastic ropes, which are distributed in a triangular shape.

[0013] Preferably, the outer wall of the upper cover plate is fixed with an elastic layer, and the outer diameter of the elastic layer is larger than the radius of the upper cylinder.

[0014] Preferably, the radius of the top opening of the conical cylinder is smaller than the radius of the upper cylinder, and the radius of the bottom opening of the conical cylinder is larger than the radius of the upper cylinder; and the tip of the conical cylinder faces the inside of the upper cylinder.

[0015] A construction method for a concrete wall panel installation structure includes the following steps:

[0016] Step 1: Lift the wall panel using a hoisting method;

[0017] Step 2: Install the guide unit onto the opening of the upper cylinder on the wall panel;

[0018] Step 3: After the wall panel moves down, the lower steel bars on the foundation press against the upper cover plate inside the guide unit of the upper cylinder.

[0019] Step four: Seal the gap between the foundation and the wall panel with concrete to form an edge seal;

[0020] Step 5: Grout through the lower grouting hole. After grout comes out, seal the upper grouting hole.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] During operation, the guide unit can guide the lower steel bars during the wall panel installation process, allowing them to enter the upper cylinder of the wall panel. After the wall is lowered, the guide unit can support the wall panel, serving as a substitute for the pad block, which is quite convenient. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Depend on Figures 1-7 The present invention relates to a concrete wall panel installation structure, comprising a foundation 1 having lower reinforcing bars 2 and a wall panel 3 having an upper cylinder 4. A gap 5 is reserved between the foundation 1 and the wall panel 3. An upper reinforcing bar 16 is fixed on the wall panel 3. An edge seal 17 is formed between the foundation 1 and the wall panel 3. A gap 5 is formed between the foundation 1, the wall panel 3 and the edge seal 17. A lower grouting hole 18, an upper grouting outlet hole 19 and a grout return hole 21 are formed inside the wall panel 3. The lower grouting hole 18 is connected to the bottom of the upper cylinder 4, the upper grouting outlet hole 19 is connected to the top of the upper cylinder 4, and the corresponding two upper cylinders 4 are connected through the grout return hole 21.

[0035] With this design, during use, in the area where the lower reinforcing bar 2 is located on the foundation 1, pads are placed on the foundation 1 according to the pre-planned support points. The pads can be rubber pads or solid wood boards. Then, the wall panel 3 is hoisted into the air so that the wall panel 3 is above the lower reinforcing bar 2 on the foundation 1. Then, the position of the wall panel 3 is gradually corrected during the descent with manual assistance. When the upper cylinder 4 on the wall panel 3 gradually approaches the lower reinforcing bar 2 on the foundation 1, the movement stops. At this time, the workers usually use a mirror to observe whether the lower reinforcing bar 2 and the upper cylinder 4 are aligned. If they are aligned, the wall panel 3 is lowered and falls on top of the pads, which support the wall panel 3. If they are not aligned, the position of the wall panel 3 is manually adjusted or the lower reinforcing bar 2 is corrected. This realizes the installation operation of the lower reinforcing bar 2 and the upper cylinder 4 during the installation of the wall panel 3.

[0036] Next, the wall panel 3 is installed from the side using an external adjustable screw, so that the wall panel 3 can remain vertical after being detached from the hoist. This installation method is existing technology, so it will not be described in detail. Then, the gap 5 is sealed with concrete using a tool. The solidified concrete after sealing is the edge seal 17. After the sealed concrete has solidified, it can be injected into the interior of the upper cylinder 4 through the lower grouting hole 18. Then, the gap 5, the other upper cylinder 4, the grout return hole 21 and the upper grout outlet hole 19 are discharged. The upper grout outlet hole 19 can then be sealed with a plug.

[0037] It should be noted that, by adopting the above method, baffles or retaining rings can be installed inside the corresponding upper cylinder 4 to ensure the smooth progress of grouting.

[0038] However, during the above operation, on the one hand, it is necessary to place shims, and on the other hand, the staff needs to observe multiple times whether the lower steel bar 2 and the upper cylinder 4 are aligned. If they are not aligned, the lower steel bar 2 needs to be corrected so that the lower steel bar 2 is located directly below the upper cylinder 4, which facilitates subsequent connection. Therefore, the operation is quite cumbersome, so a simpler method is needed.

[0039] A guide unit is provided inside the upper cylinder 4. The guide unit includes an upper cover plate 6 and a conical cylinder 7. A locking rod 8 and an elastic rope 9 are fixed on the upper cover plate 6. The conical cylinder 7 includes multiple connecting plates 10 that are spaced apart and connected to each other and an elastic pad 11. A groove 12 is opened on the connecting plate 10. A movable frame 13 is hinged in the groove 12. A torsion spring is provided at the hinge point between the movable frame 13 and the groove 12. An upper locking groove 14 is opened on the connecting plate 10, and a lower locking groove 15 is opened on the movable frame 13. The upper cover plate 6 is fixed to the connecting plate 10 by the elastic rope 9. Under normal conditions, the movable frame 13 is stored in the groove 12. The locking rod 8 passes through the upper locking groove 14 and engages with the lower locking groove 15. When in use, the locking rod 8 is disengaged from the upper locking groove 14 and the lower locking groove 15. After the movable frame 13 moves out of the groove 12, its bottom end abuts against the lower reinforcing bar 2, and its top end abuts against the wall plate 3.

[0040] With this design, the upper cover plate 6 is installed inside the upper cylinder 4 during use. The conical cylinder 7 increases the effective connection area between the upper cylinder 4 and the lower reinforcing bar 2, thereby improving the success rate of connection. The operation method is basically the same as the above method, and the specific process is as follows:

[0041] During docking, the lower reinforcing bar 2 enters the interior of the upper cylinder 4 through the conical cylinder 7, and the lower reinforcing bar 2 presses against the upper cover plate 6, causing the upper cover plate 6 to move upward and pull the elastic rope 9. Under the action of the elastic rope 9, the conical cylinder 7 is tightly pressed against the opening of the upper cylinder 4. At the same time, the movement of the upper cover plate 6 drives the locking rod 8 to move, causing the locking rod 8 to disengage from the upper locking groove 14 and the lower locking groove 15. At this time, under the action of the torsion spring, the movable frame 13 rotates around its hinge point and its bottom end is located below the wall plate 3. Then, as the wall plate 3 descends, it presses against the movable frame 13 until the bottom end of the movable frame 13 is blocked by the lower reinforcing bar 2 and stops moving. At this time, the wall plate 3 is supported by the cooperation of the movable frame 13 and the connecting plate 10, thus playing the role of replacing the pad block. There is no need to manually place the pad block, and the success rate of docking is improved.

[0042] It should be noted that initially, due to the high hardness of the lower reinforcing bar 2, the position of the connecting plate 10 can be fixed by the locking between the clamping rod 8, the upper clamping groove 14, and the lower clamping groove 15, thus preventing the connecting plate 10 from shifting after contacting the lower reinforcing bar 2, thereby improving the stability of the tapered cylinder 7 during installation.

[0043] Specifically, the upper cover plate 6 is circular in shape and has a through hole 20. With this design, during the grouting process, the concrete will first fill the space below the upper cover plate 6 inside the upper cylinder 4 through the lower grouting hole 18. At this time, the air in the space can be discharged through the through hole 20. Then, the concrete will sequentially fill the gap 5, the other upper cylinder 4, the return grout hole 21, and the space above the upper cover plate 6 inside the upper cylinder 4, and be discharged from the upper grout outlet hole 19.

[0044] It should be noted that a vent valve can be installed in the through hole 20, or a retaining ring or a retaining block can be installed in the upper cylinder 4 to limit the upper cover plate 6 and restrict the upward movement distance of the upper cover plate 6.

[0045] Specifically, the connecting plate 10 is trapezoidal in shape, and the elastic pad 11 is strip-shaped and made of silicone. This design allows the conical cylinder 7 to deform to a certain extent, which can correct the lower reinforcing bar 2 and prevent the lower reinforcing bar 2 from contacting the inner wall of the upper cylinder 4.

[0046] Specifically, the lever 8, the upper slot 14, and the lower slot 15 are set in a one-to-one correspondence, and under normal conditions, the centers of the three are located on the same axis.

[0047] Specifically, there are at least three elastic ropes 9, which are arranged in a triangular shape. Alternatively, the elastic ropes 9 can be configured in a one-to-one correspondence with the levers 8, which undoubtedly increases the effective connection strength between them.

[0048] Furthermore, an elastic layer is fixed to the outer wall of the upper cover plate 6, and the outer diameter of the elastic layer is larger than the radius of the upper cylinder 4. This design facilitates the installation of the upper cover plate 6 inside the upper cylinder 4 through the elastic layer; alternatively, the elastic layer can be omitted, and the upper cover plate 6 can be directly inserted into the opening of the upper cylinder 4 by interference fit.

[0049] Specifically, the radius of the top orifice of the conical cylinder 7 is smaller than the radius of the upper cylinder 4, while the radius of the bottom orifice of the conical cylinder 7 is larger than the radius of the upper cylinder 4; and the tip of the conical cylinder 7 faces inward toward the upper cylinder 4. This design facilitates good guiding through the conical cylinder 7, thereby expanding the effective guiding area.

[0050] A construction method for a concrete wall panel installation structure includes the following steps:

[0051] Step 1: Lift wall panel 3 using a hoisting method;

[0052] Step 2: Install the guide unit onto the opening of the upper cylinder 4 on the wall panel 3;

[0053] Step 3: After the wall panel 3 moves down, the lower steel bar 2 on the foundation 1 presses against the upper cover plate 6 in the guide unit inside the upper cylinder 4.

[0054] Step 4: Seal the gap 5 between the foundation 1 and the wall panel 3 with concrete to form the edge seal 17;

[0055] Step 5: Grout through the lower grouting hole 18. After the grout comes out, seal the upper grouting hole 19.
