Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a new type of reinforced beam using wooden formwork for shear walls. Background Technology

[0002] When constructing reinforced concrete structures, shear wall formwork is generally made of wood. The traditional reinforcement system of shear wall wood formwork consists of square timber and steel pipes. Square timber has low strength and is easily deformed under stress. Moreover, this system requires the square timber to be cut to size according to the height of the shear wall. When the height of the shear wall changes, the square timber needs to be reprocessed, resulting in material waste. Square timber has poor adaptability.

[0003] To address the low strength of square timber, a new reinforcement method has been developed, using standardized steel sections as secondary and primary beams, tightened with tie bolts. This method significantly improves the strength of the secondary beams. However, the length of the secondary beams is typically pre-fabricated according to the height of the shear wall before being transported to the site for support and installation. Therefore, these secondary beams can only be used for walls of the appropriate height; they are not universally applicable to walls of other heights, failing to completely solve the problem of poor adaptability. Furthermore, traditional secondary beams only provide contact support with the primary beams and cannot provide auxiliary overlapping, making them inconvenient to use. Therefore, we propose a new type of reinforcement beam for shear wall timber formwork to solve the aforementioned problems. Summary of the Invention

[0004] In view of this, in order to solve the problems of poor adaptability of traditional secondary beam structures and lack of auxiliary positioning function during the installation of main beams, this utility model provides a new type of reinforcing beam for shear wall wooden formwork.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel reinforcing beam for shear wall wooden formwork, comprising a keel frame and a connecting block fixedly disposed at the bottom end of the keel frame, wherein the keel frame is a U-shaped structure; U-shaped blocks are slidably disposed on the outer side of the keel frame. The U-shaped blocks are equipped with fixing components, which can fix the U-shaped blocks on the keel frame after sliding up and down. The cooperation between the U-shaped blocks and the fixing components can play an auxiliary role in the installation of the main keel and at the same time improve the support strength. The positioning rod is slidably disposed on the inner side of the keel frame and is used in conjunction with the fixing component. While operating the fixing component, the positioning rod can be controlled to move horizontally synchronously. The bottom of the connecting block is provided with a slot structure, which enables the two keel frames to be connected vertically. After the connection is completed, the positioning connection between the two keel frames is completed by the horizontal movement of the positioning rod.

[0006] Furthermore, the keel frame is integrally connected to a connecting part and two side parts. The connecting part is used for supporting the wooden template. The U-shaped block slides vertically on the outer side of the two side parts, and the positioning rod slides horizontally on the inner side of the two side parts.

[0007] Furthermore, the fixing component includes an adjusting screw passing through one side of the U-shaped block, a movable block being rotatably connected to the inner end of the adjusting screw, the movable block being slidably fitted against the inner side of both sides, and an internally threaded sleeve being threaded onto the outer wall of the adjusting screw, one end of which is fixedly connected to the outer side of the U-shaped block.

[0008] Furthermore, a knob is fixedly connected to the outer end of the adjusting screw.

[0009] Furthermore, the slot structure includes a docking slot formed on the bottom side of the connecting block. The docking slot is a rectangular slot that mates with the top of the keel frame.

[0010] Furthermore, the positioning rod includes a vertical rod that slides through the top of the movable block, the top of the vertical rod extending above the keel frame and integrally provided with a locking head; The slot structure also includes a positioning slot formed on the top wall of the docking slot, and a slot formed on the inner wall of one side of the positioning slot for the insertion and engagement of the slot head.

[0011] Furthermore, an anti-slip pad is fixedly provided on the side of the movable block away from the adjusting screw.

[0012] Furthermore, the upper and lower parts of the vertical rod are each provided with a set of sliders, each set of sliders consists of two sliders, which are fixed to the two narrow sides of the vertical rod. The inner sides of both sides are symmetrically provided with two sliding grooves that are slidably connected to the corresponding sliders.

[0013] The embodiments of this utility model have the following beneficial effects: 1. By setting U-shaped blocks that can be vertically slidably adjusted on the keel frame, and by rotating the knob, the height of the U-shaped blocks can be adjusted and fixed, thereby allowing for arbitrary adjustment according to the support height of the main beam, improving the flexibility of use; 2. The design of the internal threaded sleeve not only enables the adjustment of the adjusting screw, but also provides support and overlap for the main keel, thus facilitating the support and installation of the entire main keel. 3. By setting connecting blocks at the bottom of the keel frame, the upper and lower keel frames can be extended and connected, thus enabling them to be assembled to fit walls of different heights, improving overall adaptability. 4. By setting positioning rods inside the keel frame, and controlling the positioning rods synchronously with the knobs, the positioning connection between the upper and lower keel frames can be realized. The whole operation process is simple, and it can complete the assembly quickly, improving construction efficiency. Furthermore, the simplified operation design makes the whole structure more practical.

[0014] This invention, through the design of the connecting block, enables the vertically extended assembly of two keel frames, thereby improving overall adaptability. The height adjustment of the U-shaped block, along with the use of the internal threaded sleeve, allows for support and positioning of the main keel at different heights, while also assisting in installation, making installation easier and more convenient. Synchronous control of the positioning rod via the knob allows for both fixing the U-shaped block and simultaneously completing the positioning connection between the two keel frames, simplifying the overall operation and effectively improving construction efficiency.

[0018] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0019] Example 1: Please refer to Figures 1-5 This embodiment provides a novel reinforcing beam for shear wall timber formwork, including a frame 1, which is the main body of the entire secondary beam structure. The frame 1 is integrally connected by an abutment part 2 and two side parts 3, forming a U-shaped frame. The outer surface of the abutment part 2 is used for abutment support of the timber formwork. The structure also includes a connecting block 4 fixedly disposed at the bottom of the frame 1. The connecting block 4 can be welded later or integrally formed. One side of the connecting block 4 is vertically flush with the outer surface of the abutment part 2, enabling it to simultaneously abut and support the timber formwork with the frame 1. Even without the connecting block 4 for support, it does not obstruct the support of the frame 1. The other three sides of the connecting block 4 extend outward by 5-10mm to facilitate the opening of a mating groove 41 at its bottom that fits and engages with the top of the keel frame 1. The mating groove 41 is located on the side of the bottom of the connecting block 4 near the abutment part 2. When the keel frame 1 is assembled by extending it vertically, the connecting block 4 of the upper keel frame 1 can be inserted downwards onto the top of the lower keel frame 1, thereby completing the vertical extension between the two keel frames 1.

[0020] The secondary rib structure also includes a U-shaped block 5, which is vertically slidably connected to the outer surfaces of the two side portions 3. Guide grooves 32 are provided on the outer surfaces of both side portions 3 for guiding the sliding of the U-shaped block 5. A set of fixing components is provided on the U-shaped block 5, allowing it to be vertically slidably adjusted on the keel frame 1 and then fixed to it. Specifically, the fixing components include an adjusting screw 9 passing through one side of the U-shaped block 5, with a movable block 6 rotatably connected to the inner end of the adjusting screw 9. The movable block 6 slides against the inner surfaces of the two side portions 3. An internally threaded sleeve 8 is threaded onto the outer wall of the adjusting screw 9, with one end of the internally threaded sleeve 8 fixedly connected to the outer surface of the U-shaped block 5. Additionally, a knob 11 is fixedly connected to the outer end of the adjusting screw 9.

[0021] In use, adjust the height of the U-shaped block 5 according to the positioning height of the main keel. After adjustment, rotate the knob 11 to rotate the adjusting screw 9, causing the adjusting screw 9 to move linearly within the internal threaded sleeve 8. This, in turn, moves the movable block 6. Since the two sides of the movable block 6 abut against the inner surfaces of the two side edges 3, the movable block 6 also moves horizontally as the adjusting screw 9 moves. When the side of the movable block 6 away from the adjusting screw 9 abuts against the inner surface of the contact part 2, tightening the knob 11 can brake the U-shaped block 5, thereby fixing the U-shaped block 5 on the keel frame 1. After fixing the U-shaped block 5, the main keel can be supported and placed using the internal threaded sleeve 8. With the limit of the knob 11, the main keel can be positioned and overlapped on the internal threaded sleeve 8. The secondary rib structure designed in this utility model can be used in conjunction with existing standardized steel main ribs to complete overlapping support. It can also be used with traditional steel pipe main keels, where two steel pipes are pre-overlapped on the internally threaded sleeve 8 in a stacked manner, and then fixed with tie rods. Alternatively, one steel pipe can be overlapped first, and after the tie rods are inserted, the other steel pipe can be placed on top for positioning. After positioning, the main keel can abut against the outer side of the U-shaped block 5, increasing the contact area and thus effectively improving the support strength.

[0022] To improve the fixing strength of the U-shaped block 5, an anti-slip pad 10 is fixedly connected to the contact surface between the movable block 6 and the abutment part 2. Through the squeezing and contact between the anti-slip pad 10 and the inner side of the abutment part 2, the anti-slip degree between the movable block 6 and the abutment part 2 can be increased, thereby effectively improving the stability of the U-shaped block 5 after fixing and strengthening the support strength of the main keel.

[0023] This invention can be used in the field of novel secondary rib structures for reinforcing shear wall formwork, and can also be applied to other fields of this invention.

[0024] Example 2: This example is a further improvement on the previous example: as follows Figures 1-6 As shown, the secondary frame structure also includes a positioning rod 7 located inside the keel frame 1. The positioning rod 7 includes a vertical rod 71 that slides through the top of the movable block 6. The top of the vertical rod 71 extends to the top of the keel frame 1 and is integrally provided with a locking head 72. By rotating the knob 11 to move the movable block 6 horizontally, the entire positioning rod 7 can be moved simultaneously. When adjusting the U-shaped block 5 vertically, the adjusting screw 9 can be used to move the movable block 6 up and down on the vertical rod 71 without affecting the height adjustment of the U-shaped block 5.

[0025] Because a positioning rod 7 is installed on the inner side of the keel frame 1, and the keel frame 1 is U-shaped with a rectangular cross-section at its top, the docking slot 41 also needs to be rectangular to ensure proper engagement when the connecting block 4 is docked downwards onto the top of the keel frame 1. Furthermore, since the top of the positioning rod 7 extends upwards and the locking head 72 is located above the entire keel frame 1, a positioning groove 42 is provided on the top wall of the docking slot 41 to position the top of the positioning rod 7. This allows the extended portion of the positioning rod 7 to enter the positioning groove 42 after the connecting block 4 is engaged on the top of the keel frame 1. A locking groove 43 is provided on one inner wall of the positioning groove 42. After the connecting block 4 is engaged on the top of the keel frame 1, rotating the knob 11 moves the movable block 6, which in turn moves the vertical rod 71 synchronously, causing the locking head 72 to engage in the locking groove 43. This achieves the positioning connection between the connecting block 4 and the top of the keel frame 1, thus completing the extended connection between the upper and lower keel frames 1.

[0026] When the height of the U-shaped block 5 needs to be adjusted, simply turn the knob 11 slightly to release the movable block 6 from the squeezing contact with the inner side of the abutment part 2. This allows the movable block 6 to slide up and down on the vertical rod 71, thus adjusting the height of the U-shaped block 5. At this time, the locking head 72 is not completely disengaged from the locking slot 43. Therefore, adjusting the height of the U-shaped block 5 will not affect the positioning connection between the two keel frames 1. Only when the knob 11 is rotated to its maximum extent, that is, when the movable block 6 is stopped by the resistance of the U-shaped block 5 and cannot move outward further, will the locking head 72 disengage from the locking slot 43, allowing the two keel frames 1 to be disassembled. This design ensures the connection stability of the entire extended keel frame when adjusting the U-shaped block 5.

[0027] In addition, to ensure stable adjustment of the U-shaped block 5, a set of sliders 73 is provided at both the upper and lower parts of the vertical rod 71, with two sliders 73 in each set, fixed opposite each other on the two narrow sides of the vertical rod 71, that is, the side closest to the adjacent side 3. Two symmetrical grooves 31 are symmetrically formed on the inner surface of each side 3, arranged vertically. The four sliders 73 extend into the corresponding grooves 31 and are slidably connected to them. Through the sliding arrangement of the sliders 73 and the grooves 31, the vertical rod 71 can be horizontally limited and slid within the keel frame 1. When the U-shaped block 5 is vertically slidably adjusted on the vertical rod 71, it will not cause the entire positioning rod 7 to move up and down due to friction, thereby improving the adjustment stability of the U-shaped block 5. Of course, it can also be... Figure 1As shown, after designing the bottom end of the vertical rod 71 to abut against the top of the connecting block 4, the design of the slider 73 and the groove 31 is unnecessary. Since the top end of the vertical rod 71 is abutted and limited by the positioning latch of the connecting block 4, when adjusting the U-shaped block 5, the top and bottom ends of the entire positioning rod 7 are both abutted and limited, preventing it from moving up and down, thus ensuring the stability of the U-shaped block 5 during adjustment. Adding the slider 73 and the groove 31 prevents the positioning rod 7 from falling out or being pulled out directly, allowing it to form an integral connection with the entire structure, preventing it from falling during transportation, reducing the need for subsequent reinstallation, and making it more convenient to use.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
