Description

Technical Field

[0001] The invention belongs to the field of construction engineering, and in particular relates to an aluminum mold fastening and locking device and method. Background Art

[0002] In the existing aluminum film assembly process, the traditional aluminum mold splicing method is to fasten with steel wedges. However, the connection position cannot be locked after the traditional installation is completed, which often causes the wedge to loosen due to the vibration of the vibrating rod during the concrete pouring process, resulting in mold expansion due to lax reinforcement at the connection. The traditional construction method has major safety hazards and a large amount of labor resources are wasted, which hinders the construction progress. In addition, the traditional process cannot lock the aluminum film connection, causing the frame to vibrate during the later concrete pouring process, resulting in the loosening of the steel wedge and the risk of mold expansion. At the same time, the need for manual tapping and tightening cannot control the tightening quality, and it cannot guarantee that each reinforcement node meets the quality requirements. Summary of the invention

[0003] The problem to be solved by the present invention is to provide an aluminum mold fastening and locking device and method, which is particularly suitable for double locking and reinforcement of aluminum film plates.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: an aluminum mold fastening and locking device, comprising: a rotating rod, a fixing nail and a wedge-shaped piece, through which the tail of the fixing nail is penetrated and connected to a pair of aluminum film plates to be assembled; the wedge-shaped piece is vertically penetrated and connected to the tail of the fixing nail; the rotating rod is vertically connected to the tail of the fixing nail along a direction perpendicular to the wedge-shaped piece.

[0005] Furthermore, the head of the rotating rod is T-shaped, and the rotating rod is a rod structure except the T-shaped head. The rod structure is provided with an annular groove, and the rotating rod cooperates with the wedge-shaped piece through the annular groove to lock the aluminum membrane plate.

[0006] Furthermore, the tail of the fixing nail passes through the connecting hole on the aluminum film plate, and the head diameter of the fixing nail is larger than the diameter of the connecting hole.

[0007] Furthermore, a through cut is provided at the tail of the fixing nail along the axial direction, and the wedge-shaped piece cooperates with the fixing nail through the through cut.

[0008] Furthermore, a hole matching with the rotating rod is provided perpendicular to the through cut;

[0009] Along the direction in which the rotating rod penetrates the tail of the fixing nail, a fixing notch is transversely arranged along the axis of the hole, and the fixing notch extends to the penetration notch;

[0010] The length of the fixing cutout is greater than the diameter of the hole.

[0011] Furthermore, a rectangular groove is provided on the wedge-shaped member, and the rectangular groove cooperates with the rotating rod through the annular groove.

[0012] Furthermore, the length of the rectangular groove is greater than the diameter of the annular groove, and the annular groove is clamped in the rectangular groove.

[0013] Furthermore, the wedge-shaped piece is a quadrilateral structure with one side inclined, which is used to clamp the wedge-shaped piece.

[0014] Furthermore, the wedge-shaped member is a right-angled trapezoid, and the waist opposite to the inclined side is arranged perpendicular to one side of the aluminum film plate;

[0015] The length of the through cut is not greater than the longest length of the upper base and the lower base of the wedge-shaped plate.

[0016] To achieve the above object, the present invention also provides a method for using an aluminum mold fastening and locking device, comprising the following steps:

The application of the device can better ensure the integrity of the aluminum formwork erection system, and effectively prevent the wedge from loosening due to the vibration of the vibrating rod during the concrete pouring process, resulting in the expansion of the mold at the connection due to lax reinforcement.

[0031] The present invention will be further described below in conjunction with embodiments and drawings:

[0032] In one embodiment of the present invention, Figure 1 As shown, an aluminum mold fastening and locking device includes: a T-shaped rotating rod 1, a fixing nail 2 and a special-shaped steel wedge 3, the tail of the fixing nail 2 penetrates and connects a pair of aluminum film plates 4 that need to be assembled; the special-shaped steel wedge 3 vertically penetrates and is connected to the tail of the fixing nail 2; the T-shaped rotating rod 1 is vertically connected to the tail of the fixing nail 2 by the special-shaped steel wedge 3.

[0033] like Figure 1-2 As shown, the T-shaped rotating rod 1 is a rotating rod with a T-shaped head. The setting of the T-shaped head makes it easy to tighten the T-shaped rotating rod 1 during the construction process. The T-shaped rotating rod 1 is provided with an annular groove at the rod structure below the T-shaped head, which is similar to a gear structure. The T-shaped rotating rod 1 cooperates with the special-shaped steel wedge 3 through the annular groove. After cooperation, the special-shaped steel wedge 3 and the fixing nail 2 are locked, thereby limiting the aluminum film plate 4 to be connected to prevent the aluminum film plate 4 from being misplaced.

[0034] like Figure 1 , Figure 3 The fixing nail 2 shown has its head clamped on one side of the aluminum film plate 4, and its tail passes through the connecting holes on the pair of aluminum film plates 4 to be assembled, wherein the diameter of the head of the fixing nail 2 is larger than the diameter of the connecting hole, to prevent the fixing nail 2 from penetrating the aluminum film plate 4. A through cut is provided at the tail of the fixing nail 2 along the axial direction, and in this preferred embodiment, the through cut does not extend to the bottom end of the fixing nail, to prevent the special-shaped steel wedge 3 from falling off when it cooperates with the fixing nail 2, and to fail to achieve the purpose of fastening and locking, and the special-shaped steel wedge 3 cooperates with the fixing nail 2 through the through cut to lock the aluminum film plate 4.

[0035] The tail of the fixing nail 2 is perpendicular to the direction of the penetration incision, and is provided with a hole that cooperates with the T-shaped rotating rod 1. At the same time, a fixing incision is arranged laterally along the diameter of the hole on the side of the fixing nail 2 through which the T-shaped rotating rod 1 penetrates. The fixing incision extends to the penetration incision, and the length of the fixing incision is greater than the diameter of the hole through which the fixing nail 2 cooperates with the T-shaped rotating rod 1.

[0036] like Figure 1 , Figure 4 As shown, the special-shaped steel wedge 3 is a quadrilateral structure with one side tilted. In the preferred embodiment, the special-shaped steel wedge 3 is a right-angled trapezoidal structure. The special-shaped steel wedge 3 passes through the penetration cut on the fixing nail 2. The waist of the right-angled side of the special-shaped steel wedge 3 is close to the pair of aluminum film plates 4 to be connected. The length of the penetration cut is between the length of the upper bottom and the length of the lower bottom of the special-shaped steel wedge 3, so that the special-shaped steel wedge 3 is clamped at the penetration cut in the fixing nail 2 to achieve the fastening and locking of the aluminum film plate 4. A rectangular groove is provided on the special-shaped steel wedge 3, and the rectangular groove cooperates with the annular groove on the T-shaped rotating rod 1. During the working process, the T-shaped rotating rod 1 is pushed inward, and the annular groove on the T-shaped rotating rod 1 is inserted into the rectangular groove on the special-shaped steel wedge 3 to complete the locking.

[0037] A plurality of groups of rectangular grooves are arranged in parallel on the special-shaped steel wedge 3 , and the plurality of groups of rectangular grooves are connected at the central axis. The length of the rectangular groove is slightly greater than the length of the annular groove on the T-shaped rotating rod 1 .

[0038] The working process of an embodiment of the present invention:

[0039] 1. Assemble and dock the aluminum formwork 4;

[0040] 2. The tail of the fixing nail 2 penetrates the connection hole on the aluminum film plate;

[0041] 3. Insert the special-shaped steel wedge 3 into the penetration cut of the fixing nail 2 for initial fixation;

[0042] 4. Insert the T-shaped rotating rod 1, and drive the special-shaped steel wedge 3 to move downward through the rotation of the gear;

[0043] 5. Push the T-shaped rotating rod 1 inward, and insert the annular groove on the T-shaped rotating rod 1 into the rectangular groove on the special-shaped steel wedge 3 to complete the locking, realize self-locking of the frame, and achieve secondary reinforcement of the aluminum film system.

[0044] By setting up special-shaped steel wedges and T-shaped rotating rods, the secondary fastening of the joints can be completed, and the fine-tuning fastening of the aluminum mold system can be achieved. This can effectively prevent the wedge from loosening due to the vibration of the vibrating rod during the concrete pouring process, which can cause the joints to expand due to poor reinforcement.

[0045] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
