Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a locking mechanism for aluminum formwork and wooden formwork. Background Technology

[0002] In the construction of super high-rise residential buildings, refuge floors with special structures are usually arranged to meet the needs of refuge. Since the refuge floors cannot be constructed using the same aluminum formwork as the standard floors, wooden formwork can make up for the shortcomings of aluminum formwork in the construction of refuge floors. In actual construction, the combination of aluminum and wood formwork can give full play to the advantages of aluminum formwork in structural construction, and can also utilize the flexibility of wooden formwork to adapt to the special structure of the refuge floor, ensuring the stability and safety of the refuge floor structure, while avoiding construction delays and effectively saving construction costs.

[0003] However, due to the differences in physical properties between aluminum and wood, existing technology cannot simultaneously adapt to the connection requirements of the two types of templates. Gaps are easily generated at the joints between aluminum and wood templates, leading to grout leakage during concrete pouring and affecting construction quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a locking mechanism for aluminum and wooden formwork, which aims to improve the problem that gaps easily occur when connecting formwork of different materials in the existing technology, thus affecting the quality of pouring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum template and a wooden template locking mechanism, comprising an aluminum template, an aluminum template outer frame fixedly connected to the surface of the aluminum template, a wooden template outer frame attached to the top of the aluminum template outer frame, a wooden template fixedly connected to the inner wall of the wooden template outer frame, a rotating head attached to the top of the inner wall of the aluminum template outer frame, a screw fixedly connected to the top of the rotating head, a wedge rotatably connected to the top of the screw, a movable block attached to the surface of the wooden template, a movable groove provided inside the movable block, and a reinforcing mechanism provided on the surface of the movable block; The above technical solution converts rotation into displacement of a moving block using a screw, thus achieving locking between the wooden template and the aluminum template.

[0006] Preferably, the reinforcing mechanism includes a fixed plate, which is fixedly connected to the movable block. One side surface of the fixed plate is in contact with the wooden template. A circular connecting ring is fixedly connected to the surface of the fixed plate, and a circular long rod is attached to the inner wall of the circular connecting ring. The above technical solution allows for the quick insertion of multiple circular connecting rings, improving installation efficiency while avoiding insertion jamming and reducing wear on the circular connecting rings.

[0007] Preferably, the reinforcing mechanism further includes a rectangular connecting ring, which is fixedly connected to the fixing plate, and a rectangular long rod is attached to the inner wall of the rectangular connecting ring; The above technical solution allows for a larger contact area between the rectangular rod and the rectangular connecting ring, which helps to evenly transfer lateral pressure to the fixing plate, thereby ensuring consistent lateral pressure at each stress point of the wooden mold.

[0008] Preferably, the top of the aluminum mold outer frame is provided with a first connecting hole, and the screw is threadedly connected to the inner wall of the first connecting hole.

[0009] Preferably, the bottom of the wooden mold outer frame is provided with a second connecting hole, and the screw is threadedly connected to the inner wall of the second connecting hole.

[0010] Preferably, the bottom of the movable block is in contact with the outer frame of the wooden mold, the surface of the wedge block is in contact with the inner wall of the movable groove, and the surface of the screw is in contact with the inner wall of the movable groove.

[0011] Preferably, the wooden template surface is fixedly connected with reinforcing ribs, and both the aluminum template and the wooden template surface are fitted with reinforcing frames, with fixing columns fixedly connected to the inner wall of the reinforcing frames.

[0012] Preferably, both sides of the aluminum mold outer frame are fitted with connectors, and fixing holes are provided on the surfaces of both the aluminum mold outer frame and the connectors.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the screw is controlled by rotating the rotating head to extend into the outer frame of the aluminum mold and the outer frame of the wooden mold. At the same time, when the screw rotates, it drives the wedge to move upward along the internal moving groove of the moving block, thereby driving the moving block to come closer to the wooden template. Through the combined action of the screw, the moving block and the wedge, a better fixing effect between the aluminum template and the wooden template is achieved, avoiding the phenomenon of grout leakage during the pouring process.

[0014] 2. In this utility model, the local dynamic load is distributed to multiple moving blocks by a long rod, which can transfer the impact load borne by a single moving block to multiple moving blocks to share the load, thereby avoiding excessive local pressure at the connection between the wooden mold and the aluminum mold.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Reference Figures 1-3 An embodiment of this utility model provides: an aluminum template and a wooden template locking mechanism, including an aluminum template 1, an aluminum template outer frame 3 fixedly connected to the surface of the aluminum template 1, a wooden template outer frame 6 attached to the top of the aluminum template outer frame 3, a wooden template 2 fixedly connected to the inner wall of the wooden template outer frame 6, a rotating head 12 attached to the top of the inner wall of the aluminum template outer frame 3, a screw 13 fixedly connected to the top of the rotating head 12, a wedge block 14 rotatably connected to the top of the screw 13, a movable block 9 attached to the surface of the wooden template 2, a movable groove 21 opened inside the movable block 9, and a reinforcing mechanism provided on the surface of the movable block 9; Specifically, the aluminum formwork frame 3 can reduce the deformation of the edges of the aluminum formwork 1 during assembly and use. By rotating the rotating head 12, the screw 13 can be driven to extend into or retract from the formwork connection. At the same time, the rotation of the screw 13 can drive the wedge block 14 to move. The wedge block 14 can drive the moving block 9 to move together, thereby realizing the transmission of pressure to the wooden formwork 2 through the moving block 9. By connecting the wooden formwork outer frame 6 and the aluminum formwork outer frame 3 with screws 13, the wooden formwork 2 and a single aluminum formwork 1 can be connected on the same plane to increase the height. By fixing the aluminum formwork 1 and the wooden formwork 2 to both sides of the connector 8, the width of the wall column can be increased.

[0019] Reference Figure 3The strengthening mechanism includes a fixed plate 15, which is fixedly connected to the movable block 9. One side surface of the fixed plate 15 is in contact with the wooden template 2. A circular connecting ring 16 is fixedly connected to the surface of the fixed plate 15, and a circular long rod 17 is attached to the inner wall of the circular connecting ring 16. Specifically, by using a long rod to pass through the connecting ring at the top of all the moving blocks 9, the pressure of the moving blocks 9 is synchronized, and the positions of multiple moving blocks 9 are kept consistent. When tightening the rotating head 12 one by one during construction, the long rod can limit the excessive tightening of a single moving block 9 to avoid excessive local pressure.

[0020] Reference Figures 3-4 The top of the aluminum mold outer frame 3 is evenly provided with first connecting holes 10, and the screw 13 is threadedly connected to the inner wall of the first connecting hole 10. Specifically, by rotating the rotating head 12, the screw 13 can be precisely moved along the inner wall of the first connecting hole 10 with the help of the threaded guide, thereby driving the wedge block 14 at the top to adjust its position synchronously, which provides a basis for locking between the wooden template 2 and the aluminum template 1.

[0021] Reference Figures 3-4 The bottom of the wooden mold outer frame 6 is evenly provided with second connecting holes 11, and the screw 13 is threadedly connected to the inner wall of the second connecting hole 11. Specifically, the second connecting hole 11 corresponds to some of the positions of the first connecting holes 10. By connecting the moving block 9 and the screw 13 to the second connecting holes 11 at different positions, the appropriate hole position can be selected according to the splicing requirements.

[0022] Reference Figures 3-4 The bottom of the movable block 9 is in contact with the outer frame of the wooden mold 6, the surface of the wedge block 14 is in contact with the inner wall of the movable groove 21, and the surface of the screw 13 is in contact with the inner wall of the movable groove 21. Specifically, the moving slot 21 provides space for the movement of the rotating head 12 and the wedge block 14, ensuring that the rotating head 12 and the wedge block 14 can be displaced vertically inside the moving block 9.

[0023] Reference Figure 1 The wooden template 2 is fixedly connected with reinforcing ribs 7, and both the aluminum template 1 and the wooden template 2 are fitted with reinforcing frames 5. The inner wall of the reinforcing frames 5 is fixedly connected with fixing columns 4. Specifically, the reinforcing ribs 7 can enhance the lateral pressure resistance of the wooden formwork 2 to a certain extent. The fixing columns 4 are distributed at the four corners of the reinforcing frame 5. The joint action of the fixing columns 4 and the reinforcing frame 5 can strengthen the connection strength between the formwork and prevent the formwork from sinking or deforming due to local stress concentration when it is subjected to the pressure of concrete pouring, thus affecting the pouring operation.

[0024] Reference Figure 1Both sides of the aluminum mold outer frame 3 are fitted with connectors 8, and fixing holes 20 are opened on the surface of both the aluminum mold outer frame 3 and the connectors 8. Specifically, the joint action of connector 8 and fixing hole 20 enables vertical connection between two templates and ensures that they remain vertical after splicing, without shifting due to external force collision, vibration or lateral pressure generated by concrete pouring during construction.

[0025] Example 2: Reference Figure 5 The reinforcing mechanism also includes a rectangular connecting ring 18, which is fixedly connected to the fixing plate 15, and a rectangular long rod 19 is attached to the inner wall of the rectangular connecting ring 18. Specifically, by making the cross-section of the long rod rectangular, the lateral pressure can be evenly transmitted to the fixed plate 15 through the plane of the rectangular long rod 19, avoiding local stress concentration.

[0026] Working principle: The rotating head 12 controls the screw 13 to extend into the aluminum formwork outer frame 3 and the wooden formwork outer frame 6 to connect the aluminum formwork 1 and the wooden formwork 2. At the same time, when the screw 13 rotates, it drives the wedge block 14 to move upward along the moving groove 21 inside the moving block 9, thereby driving the moving block 9 to come closer to the wooden formwork 2. This achieves continuous pressure on the wooden formwork 2 in the horizontal position through the moving block 9. Through the combined action of the moving block 9 and the wedge block 14, a good fixing effect is achieved between the aluminum formwork 1 and the wooden formwork 2. At the same time, it is relatively easy to release the fixing so as to adjust the formwork assembly according to the construction needs. In addition, dynamic lateral pressure is generated during the concrete pouring process. The local dynamic load is distributed to multiple moving blocks 9 through the long rod, and the impact load borne by a single moving block 9 is transferred to multiple moving blocks 9 to be borne together.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
