Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a formwork fixing device for building engineering. Background Technology

[0002] In the field of construction engineering, formwork fixing is a crucial step in concrete pouring, and its effectiveness directly affects the quality of concrete components and the stability of building structures. However, traditional formwork fixing methods and devices in construction engineering have many problems that cannot be ignored.

[0003] 1. Fixing Accuracy and Stability Issues: Traditional fixing methods, such as simple wooden supports with wire binding, struggle to accurately control the position and verticality of the formwork. In large-scale construction projects, the dimensional accuracy requirements for concrete components are extremely high. With traditional fixing methods, the formwork is prone to displacement and deformation during concrete pouring due to insufficient support or weak connections, leading to dimensional deviations in the concrete components and affecting subsequent construction procedures and the overall quality of the building. For example, in the construction of high-rise residential buildings, displacement of the wall formwork can cause uneven wall thickness, affecting not only aesthetics but also potentially reducing the wall's load-bearing capacity.

[0004] 2. Operational Ease of Use: Traditional formwork fixing procedures are cumbersome and complex, requiring construction workers to expend a significant amount of time and effort. Taking bolted formwork fixing as an example, each bolt must be tightened individually during installation, and repeated disassembly and tightening are necessary when adjusting the formwork position, resulting in low efficiency. In projects with tight schedules, this method of operation severely delays construction progress and increases labor costs.

[0005] 3. Issues with versatility and adaptability: Existing fixing devices lack versatility and struggle to adapt to diverse building structures and formwork types. Different construction projects may use formwork made of different materials (such as wood, steel, and aluminum) and in different specifications. Traditional fixing devices often only provide fixation for specific types of formwork, lacking flexibility. In the construction of some irregularly shaped building structures, traditional fixing devices are even less able to meet the fixing requirements of complex formwork, limiting innovation in architectural design and the development of construction technology.

[0006] 4. Durability and Maintenance Costs: Construction sites are harsh environments where fixtures are constantly exposed to wind, sun, rain, and mechanical impacts. Traditional fixtures, with their inadequate materials and structural design, suffer from severe wear and corrosion, resulting in short lifespans. Frequent replacements not only increase construction costs but also disrupt the continuity and efficiency of construction. For example, some iron fixtures are prone to rusting in humid environments, leading to loose connections and rendering them unusable.

[0007] Given the aforementioned problems with traditional formwork fixing devices in construction engineering, it is urgent to develop a new type of formwork fixing device that is highly accurate, stable, easy to operate, versatile, and durable. This is of great practical significance for improving construction quality, increasing construction efficiency, and reducing construction costs. Utility Model Content

Detailed Implementation

[0024] like Figures 1 to 4As shown, this specific embodiment adopts the following technical solution: a building formwork fixing device, including: a building formwork 1, and further including a base 2, a groove 3, a mounting seat 4, a sliding seat 5, a fixing block 6, a locking bolt 7, a U-shaped seat 8, a locking pin 9, a connecting rod 10, and an adjuster 11; the mounting seat 4 is fixedly connected to the left side of the upper surface of the base 2, and the building formwork 1 is hinged to the mounting seat 4; the upper surface of the base 2 is provided with a groove 3, and the sliding seat 5 is slidably connected in the groove 3; fixing blocks 6 are fixedly connected to both sides of the sliding seat 5, and locking bolts 7 for locking are threadedly connected to the fixing blocks 6; U-shaped seats 8 are fixedly connected to the upper right side of the building formwork 1 and the sliding seat 5; connecting rods 10 are hinged to the U-shaped seats 8 through locking pins 9; and an adjuster 11 is connected between the connecting rods 10.

[0025] like Figures 1 to 4 As shown, the specific structure of the regulator 11 includes a cover 12, an optical shaft 13, a bushing 14, a bearing seat 15, a first rotating shaft 16, a forward thread 17, a reverse thread 18, a moving sleeve 19, a connecting shaft 20, an L-shaped rod 21, a first bevel gear 22, a second bevel gear 23, a second rotating shaft 24, a handwheel 25, and a locking device. The optical shaft 13 is fixedly connected to the left side of the cavity of the cover 12. Bushings 14 are slidably connected to both ends of the optical shaft 13. Bearing seats 15 are fixedly connected to the upper and lower ends of the cavity of the cover 12. The first rotating shaft 16 is movably connected between the bearing seats 15. The upper outer surface of the first rotating shaft 16 is integrally formed with a forward thread 17, and the lower outer surface of the first rotating shaft 16 is integrally formed with a reverse thread. 18; Both the forward thread 17 and the reverse thread 18 are threadedly connected to a movable sleeve 19; the left side of the movable sleeve 19 is fixedly connected to the corresponding bushing 14 via a connecting shaft 20; an L-shaped rod 21 is fixedly connected to the right side of each movable sleeve 19, and the L-shaped rod 21 is fixedly connected to the corresponding connecting rod 10; a first bevel tooth 22 is fixedly connected to the middle position of the second rotating shaft 24; a second rotating shaft 24 is movably connected to the middle position of the right side of the cover 12; a handwheel 25 is fixedly connected to the right end of the second rotating shaft 24, and a second bevel tooth 23 is fixedly connected to the left end of the second rotating shaft 24, the second bevel tooth 23 meshing with the first bevel tooth 22; a locking device is provided on the outer surface of the second rotating shaft 24.

[0026] like Figures 1 to 4As shown, the specific structure of the locking device includes a tapered rotating wheel 26, a pneumatic cylinder 27, a fixing rod 28, and a tapered locking wheel 29; the tapered rotating wheel 26 is fixedly connected to the outer surface of the second rotating shaft 24 exposed on the outer surface of the cover 12; the pneumatic cylinder 27 is fixedly connected to the middle of the right side of the cover 12; the tapered locking wheel 29 is provided on the outer surface of the tapered rotating wheel 26; the fixing rod 28 is fixedly connected to the output end of the pneumatic cylinder 27, and the other end of the fixing rod 28 is fixedly connected to the tapered locking wheel 29.

[0027] The tapered rotating wheel 26 and the tapered locking wheel 29 are both coated with a wear-resistant coating; the first bevel tooth 22 and the second bevel tooth 23 are both coated with grease; and the handwheel 25 is provided with anti-slip texture.

[0028] The usage state of this utility model is as follows: (1) Device foundation positioning and preliminary template placement: The base 2 is placed at the predetermined position on the construction site, and the mounting seat 4 fixedly connected to the left side of the upper surface of the base 2 is in a state ready to receive the building template 1. The building template 1 is hinged to the mounting seat 4 to complete the preliminary placement of the template, so that the template has an adjustable foundation structure. At the same time, the sliding seat 5 can be adjusted in position according to actual needs in the groove 3 on the upper surface of the base 2. The locking bolts 7 on the fixing blocks 6 on both sides of the sliding seat 5 are in a loose state, which makes it convenient for the sliding seat 5 to slide in the groove 3. After the sliding seat 5 is adjusted to a suitable position, the locking bolts 7 are tightened to fix the sliding seat 5 on the base 2, providing stable support for subsequent precise adjustment of the template angle.

[0029] (2) Preliminary adjustment of template angle: The hinged structure between the building template 1 and the mounting base 4 allows the template to be rotated manually. According to the design requirements of the building components, the construction personnel initially rotate the building template 1 to make approximate angle adjustments. At this time, the U-shaped base 8, which is fixedly connected to the upper right side of the building template 1 and the sliding base 5, is hinged to the connecting rod 10 through the locking pin 9. The connecting rod 10 is in a natural swinging state when the template is initially rotated, which prepares for subsequent precise adjustment.

[0030] (3) Precise adjustment of template angle: Rotate handwheel 25, which drives the second rotating shaft 24 fixedly connected to it to rotate. The second bevel tooth 23 fixed at the left end of the second rotating shaft 24 rotates accordingly. Since the second bevel tooth 23 meshes with the first bevel tooth 22, the first bevel tooth 22 drives the first rotating shaft 16 fixed to it to rotate. The forward thread 17 and the reverse thread 18 on the first rotating shaft 16 drive the moving sleeve 19 to move axially. The left side of the moving sleeve 19 is fixedly connected to the bushing 14 through the connecting shaft 20. The bushing 14 slides on the optical shaft 13, which plays a guiding role to ensure that the moving sleeve 19 moves smoothly. The L-shaped rod 21 fixedly connected to the right side of the moving sleeve 19 moves synchronously with the moving sleeve 19. The L-shaped rod 21 drives the connecting rod 10 to move. The connecting rod 10 pushes the building template 1 to rotate around the hinge point of the mounting base 4, thereby realizing the precise adjustment of the verticality and angle of the building template 1 and meeting the high-precision positioning requirements of the template before concrete pouring.

[0031] (4) Template fixing and locking: After the template is precisely adjusted, start the pneumatic cylinder 27. The output end of the pneumatic cylinder 27 pushes the fixing rod 28, and the fixing rod 28 drives the tapered locking wheel 29 to move towards the tapered rotating wheel 26 fixed on the outer surface of the second rotating shaft 24 until the tapered locking wheel 29 is tightly attached to the tapered rotating wheel 26. By using the friction and tapered fit between the two, the second rotating shaft 24 is locked to prevent it from rotating due to external forces during concrete pouring, ensuring that the building template 1 remains stable and fixed during concrete pouring, and avoiding displacement and deformation.

[0032] (5) Stability Maintenance During Construction: During concrete pouring, the various components of the device work together to maintain the stability of the formwork 1. The base 2 and sliding seat 5 provide stable support for the formwork, preventing overall displacement; the mounting seat 4 and hinge structure ensure the stability of the formwork at a fixed angle; the locking structure of the adjuster, namely the tapered roller 26, tapered locking roller 29, pneumatic cylinder 27 and fixing rod 28, work together to ensure that the formwork will not change angle due to the impact and pressure of pouring. In addition, the wear-resistant coating on the tapered roller 26 and tapered locking roller 29, and the lubricating grease on the first bevel tooth 22 and the second bevel tooth 23, respectively reduce wear and friction between components, ensuring stable operation of the device in harsh construction environments and ensuring the quality of concrete component pouring.
