Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a secondary structure anti-reinforcement formwork device. Background Technology

[0002] In building construction, secondary structure refers to the construction of non-load-bearing components (such as infill walls and structural columns) after the main structure (such as beams, slabs, and columns) has been completed. Since the surface of the completed structural floor slab usually has a waterproof layer, insulation layer, or finishing layer, the retaining wall (a waterproof sill often used in bathrooms, balconies, etc., which is an upward extension of the floor structure) in the secondary structure cannot be directly connected to the lower structure, thus creating a height difference in the construction location. When pouring concrete in this retaining wall structure, the formwork needs to withstand the lateral pressure of the newly poured concrete, placing high demands on the stability of the formwork support system.

[0003] Existing secondary structure anti-reinforcement formwork devices adjust the height of steel plates through threaded connections between outer and inner pipes. When large-distance adjustments are needed, the threaded adjustment is slow and cannot quickly adjust the plate height. Furthermore, existing support steel plates are typically fixed structures, preventing angle adjustment. When the floor slab is uneven or sloped, the fixed-angle steel plate will make point contact with the floor slab, causing localized stress concentration at the support point. This can easily lead to surface damage to the floor slab, such as indentations and cracks, reducing the stability of the support. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a secondary structure anti-sill formwork reinforcement device, which features the ability to quickly raise and lower the steel plate and rotate the steel plate according to the floor slab angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a secondary structure anti-sill template reinforcement device, comprising a square tube, with sliding rods slidably connected to both ends of the square tube, bolts threadedly connected to the upper ends of the square tube at positions corresponding to the sliding rods, a connecting rod fixed to the end of the sliding rod away from the square tube, clamping plates fixed to the lower ends of the connecting rods, an anti-sill wooden template provided at one end of the clamping plate, and a steel plate provided on the upper side of the square tube, with the steel plate and the square tube connected by a lifting assembly; The lifting assembly includes a fixed cylinder. The fixed cylinder is fixed at the middle of the upper end of the square tube. A sliding plate is slidably connected in the fixed cylinder. A sliding column is fixed at the upper end of the sliding plate. Bolts are threaded to the upper sides of both ends of the fixed cylinder. Several fixing holes corresponding to bolts are opened at both ends of the sliding column. A stud is threaded to the upper side of the inside of the sliding column. A threaded groove corresponding to the stud is opened on the upper side of the inside of the sliding column. A top plate is provided at the upper end of the stud. A limit component is provided at the lower end of the stud.

[0006] Preferably, the limiting component includes a base plate, the lower end of the stud is rotatably connected to the base plate through a thrust bearing, the slide column has a cavity adapted to the base plate, guide keys are symmetrically arranged on both sides of the base plate, and the inner wall of the cavity has a keyway corresponding to slide with the guide key.

[0007] Preferably, a nut is fixed to the upper end of the stud surface, and the stud is rotatably connected to the base plate and to the top plate.

[0008] Preferably, the upper sides of both ends of the fixed cylinder are provided with through holes corresponding to the second bolt, and the upper end of the fixed cylinder is provided with a sliding hole corresponding to the sliding column.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by setting up a lifting component, pushes the sliding column and the sliding plate to slide in the fixed cylinder for large-distance movement. When there is a small gap between the upper end of the steel plate and the bottom surface of the floor slab, the bolt is screwed into the corresponding fixing hole on the side of the sliding column to fix the sliding column. Then, the stud can be rotated to move upward in the screw groove of the sliding column, thereby pushing the upper end of the steel plate to press against the bottom surface of the floor slab, thus completing the stable support of the anti-slab wooden formwork. The lifting component facilitates the rapid lifting and adjustment of the steel plate over a large distance, improving the practicality of the equipment. Attached Figure Description

[0011] 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.

[0012] Example 1 Please see Figure 1-3 The present invention provides the following technical solution: a secondary structure anti-sill template reinforcement device, including a square tube 1, with sliding rods 9 slidably connected to both ends of the square tube 1, bolts 6 threadedly connected to the upper ends of the square tube 1 at positions corresponding to the sliding rods 9, a connecting rod 7 fixed to the end of the sliding rods 9 away from the square tube 1, clamping plates 4 fixed to the lower ends of the connecting rods 7, an anti-sill wooden mold 8 provided at one end of the clamping plate 4, and a steel plate 5 provided on the upper side of the square tube 1, with the steel plate 5 connected to the square tube 1 by a lifting assembly 2; The lifting assembly 2 includes a fixed cylinder 21. The fixed cylinder 21 is fixed at the middle position of the upper end of the square tube 1. A sliding plate 24 is slidably connected in the fixed cylinder 21. A sliding column 25 is fixed at the upper end of the sliding plate 24. Bolts 23 are threadedly connected to the upper sides of both ends of the fixed cylinder 21. Several fixing holes 27 corresponding to bolts 23 are opened at both ends of the sliding column 25. A stud 26 is threadedly connected to the upper side of the inside of the sliding column 25. A screw groove 29 corresponding to the stud 26 is opened on the upper side of the inside of the sliding column 25. A top plate 22 is provided at the upper end of the stud 26. A limit assembly 28 is provided at the lower end of the stud 26.

[0013] Specifically, the limiting component 28 includes a base plate 281, and the lower end of the stud 26 is rotatably connected to the base plate 281 via a thrust bearing. The sliding column 25 has a cavity 282 that matches the base plate 281. Guide keys 283 are symmetrically arranged on both sides of the base plate 281, and the inner wall of the cavity 282 has a keyway 284 that slides with the guide keys 283. By adopting the above technical solution, when the stud 26 rotates, it drives the base plate 281 to slide in the cavity 282 of the sliding column 25. The thrust bearing is used to reduce the frictional resistance when the stud 26 rotates, and to avoid jamming caused by the rotation of the base plate 281. Meanwhile, the guide keys 283 at both ends of the base plate 281 slide in the keyway 284. The guide keys 283 enhance the axial guiding accuracy, prevent the stud 26 from wobbling radially, and improve the lifting stability. The keyway 284 and the guide keys 283 cooperate to form a reliable sliding pair, ensuring that the base plate 281 can only move axially. The limiting component 28 can limit the stud 26 and prevent the stud 26 from moving too far and separating from the slide 25.

[0014] Specifically, a nut is fixed to the upper surface of the stud 26, and the stud 26 is rotatably connected to the base plate 281 and the top plate 22. By adopting the above technical solution, the nut and the stud 26 can be rotated by a wrench, and the stud 26 can rotate between the base plate 281 and the top plate 22.

[0015] Specifically, the upper sides of both ends of the fixed cylinder 21 are provided with through holes corresponding to the second bolt 23, and the upper end of the fixed cylinder 21 is provided with sliding holes corresponding to the sliding column 25. By adopting the above technical solution, the second bolt 23 can be inserted into the fixed cylinder 21 and screwed into the corresponding fixing hole 27 on the side of the sliding column 25, and the sliding column 25 can slide on the upper end of the fixed cylinder 21.

[0016] In this embodiment, the sliding rod 9 is adjusted to slide in the square tube 1 according to the distance between the two anti-reverse wooden molds 8. At this time, the upper end of the anti-reverse wooden mold 8 is in close contact with the lower end of the connecting rod 7, and the side of the anti-reverse wooden mold 8 is in close contact with the side of the clamping plate 4. The bolt 6 is tightened to press the sliding rod 9 to fix it, thereby preventing lateral movement between the two anti-reverse wooden molds 8. Then, the sliding column 25 and the sliding plate 24 are pushed to slide in the fixed cylinder 21 for large-distance movement. When there is a small gap between the upper end of the steel plate 5 and the bottom surface of the floor slab, the bolt 23 is screwed into the corresponding fixing hole 27 on the side of the sliding column 25 to fix the sliding column 25. Then, the stud 26 can be rotated to move upward in the screw groove 29 of the sliding column 25, thereby pushing the upper end of the steel plate 5 to press against the bottom surface of the floor slab, completing the stable support of the anti-reverse wooden mold 8. The lifting component 2 is set to facilitate the rapid lifting and adjustment of the steel plate 5 over a large distance, improving the practicality of the equipment.

[0017] When the stud 26 rotates, it drives the base plate 281 to slide in the cavity 282 of the slide column 25. The thrust bearing is used to reduce the frictional resistance when the stud 26 rotates, and to prevent the base plate 281 from getting stuck due to rotation. At the same time, the guide keys 283 at both ends of the base plate 281 slide in the keyway 284. The guide keys 283 enhance the axial guiding accuracy, prevent the stud 26 from wobbling radially, and improve the lifting stability. The keyway 284 and the guide keys 283 cooperate to form a reliable sliding pair, ensuring that the base plate 281 can only move axially. The limiting component 28 can limit the stud 26 and prevent the stud 26 from moving too far and separating from the slide column 25.

[0018] The working principle and usage process of this utility model are as follows: First, install the device in a suitable position. Adjust the sliding rod 9 to slide in the square tube 1 according to the distance between the two anti-reverse wooden molds 8. At this time, the upper end of the anti-reverse wooden mold 8 is in close contact with the lower end of the connecting rod 7, and the side of the anti-reverse wooden mold 8 is in close contact with the side of the clamping plate 4. Tighten the bolt 6 to press the sliding rod 9 to fix the sliding rod 9, thereby preventing lateral movement between the two anti-reverse wooden molds 8. Then push the sliding column 25 and the sliding plate 24 to slide in the fixed cylinder 21 for large-distance movement. When there is a small gap between the upper end of the steel plate 5 and the bottom surface of the floor slab, screw the bolt 23 into the corresponding fixing hole 27 on the side of the sliding column 25 to fix the sliding column 25. Then, the stud 26 can be rotated to move upward in the screw groove 29 of the sliding column 25, thereby pushing the upper end of the steel plate 5 to press against the bottom surface of the floor slab, completing the stable support of the anti-reverse wooden mold 8. The lifting component 2 is set to facilitate the rapid large-distance lifting and adjustment of the steel plate 5, improving the practicality of the equipment.

[0019] When the stud 26 rotates, it drives the base plate 281 to slide in the cavity 282 of the slide column 25. The thrust bearing is used to reduce the frictional resistance when the stud 26 rotates, and to prevent the base plate 281 from getting stuck due to rotation. At the same time, the guide keys 283 at both ends of the base plate 281 slide in the keyway 284. The guide keys 283 enhance the axial guiding accuracy, prevent the stud 26 from wobbling radially, and improve the lifting stability. The keyway 284 and the guide keys 283 cooperate to form a reliable sliding pair, ensuring that the base plate 281 can only move axially. The limiting component 28 can limit the stud 26 and prevent the stud 26 from moving too far and separating from the slide column 25.
