Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a liftable precast beam rebar binding formwork. Background Technology

[0002] Reinforcing bars are a traditional building material, often used in the construction of mold supports. Traditional precast beams are equipped with connecting reinforcing bar supports. Since multiple sets of reinforcing bars need to be fixed together during the welding process, a formwork frame is usually used for fixing. However, when hoisting after binding, the weight of the reinforcing bars causes them to bend, which can lead to them hitting the fixed position of the formwork frame and getting stuck. This makes it difficult to detach and fix the structure. Multiple hoists need to be used at the same time, which is time-consuming and labor-intensive. Moreover, it lacks good applicability to different steel products, such as angle steel and steel rings. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a liftable precast beam rebar binding formwork that is simple in structure, applicable to a variety of steel products, and effectively assists in the hoisting and detachment of rebars.

[0004] The technical solution adopted in this utility model is a liftable precast beam rebar binding formwork frame, which includes two sets of longitudinally arranged longitudinal rebar fixing mechanisms and two sets of transversely arranged transverse rebar fixing plates. Several rebars are mounted between the two sets of longitudinal rebar fixing mechanisms. Several fixing parts are provided on the transverse rebar fixing plates to fix the rebars mounted on the transverse rebar fixing plates. Several lifting mechanisms are provided between the two sets of transverse rebar fixing plates to lift the rebars to detach them from the equipment.

[0005] In one embodiment, the longitudinal rib fixing mechanism includes two sets of staggered fixing plates, which are offset against each other. The longitudinal rib fixing mechanism is provided with a plurality of fixing grooves, which are arranged in a linear array on one side of the staggered fixing plates.

[0006] In one embodiment, the fixing groove is a rectangular groove; or a V-shaped groove; or a semi-circular groove.

[0007] In one embodiment, the two sets of misaligned fixing plates are provided with a plurality of fixing blocks on the side away from the abutment surface, and the fixing blocks on the same side are provided with threaded rods in the middle, the threaded rods passing through and spirally connected to the fixing blocks, and the two ends of the threaded rods passing through and rotatably connected to the transverse rib fixing plates.

[0008] In one embodiment, the fastener includes a top groove located on the mounting side of the transverse rib fixing plate. Two sets of constraint rods are provided in the middle of the top groove. The constraint rods are hinged to the middle of the concave side of the top groove via extension blocks. A constraint frame is provided between the two sets of constraint rods near the end of the top groove, and the constraint frame abuts against the adjacent constraint rods.

[0009] In one embodiment, the horizontal rib fixing plate has a plurality of bottom grooves on the side away from the top groove. The bottom grooves are located on the side of the horizontal rib fixing plate away from the top groove. A rotating gear is provided in the middle of the bottom groove. The constraint frame is also provided with a lifting rod. The lifting rod has a plurality of linear array meshing teeth on the side facing the rotating gear. The rotating gear meshes with the adjacent meshing teeth.

[0010] In one embodiment, a rotating rod is provided in the middle of a plurality of rotating gears. The rotating rod passes through and is fixedly connected to the rotating gears. The rotating rod passes through and is rotatably connected to the middle of the horizontal rib fixing plate. A rotating motor is provided on the horizontal rib fixing plate, and the rotating motor drives the rotating rod to rotate.

[0011] In one embodiment, the lifting mechanism includes a lifting plate disposed between opposing transverse rib fixing plates. The lifting plate has lifting racks at both ends, which mesh with adjacent rotating gears. Movable blocks are provided on both sides of the lifting racks, and a guide post is provided in the middle of the movable blocks. The guide post passes through and is slidably connected to the movable blocks, and connecting plates are fixedly connected to the transverse rib fixing plates at both ends of the guide post.

[0012] The beneficial effects of this utility model are as follows: a liftable precast beam rebar binding formwork with a simple structure, applicable to various steel products, and effectively assisting in the hoisting and detachment of rebars. The specific implementation method is as follows: The operator first evenly drops the steel bars into the fixing groove of the staggered fixing plate bracket, then rotates the threaded rod. The staggered fixing plate is driven to move by the abutment of the staggered fixing plate and the connection of the fixing block. Then, one of the threaded rods is rotated individually to make the two sets of staggered fixing plates misaligned, and the steel bars that have fallen into the fixing groove can be fixed. After the reinforcing bars are placed between the constraint rods in the top groove of the horizontal reinforcement fixing plate, the rotating rod is rotated to drive the rotating gear to rotate. The meshing teeth drive the lifting rod and the constraint frame to move upward. As the constraint frame moves, it drives the two sets of constraint rods to fold along the hinge direction so that the constraint rods clamp the reinforcing bars. Then the rotating rod can be stopped, and the two sets of intersecting reinforcing bars can be tied or welded. After the fixing is completed, the rotating motor drives the rotating rod to rotate in the opposite direction. Under the action of the rotation, the rotating gear drives the lifting rod to fall, causing the two sets of constraint rods to lose the constraint of the constraint frame and expand to form a V-shaped structure. At the same time, it drives the lifting rack on the other side to lift the lifting plate along the guide column to guide the moving block. The horizontal rib fixing plate and the misaligned fixing plate of the fixed structure are removed from the whole structure. This can avoid the difficulty of separation caused by the gravity deformation of the membrane frame during the hoisting of the structure. At the same time, it is suitable for fixing different steel bars or steel plates, steel rings and other structures. The equipment has a simple structure, effectively utilizes a simple clamping structure for fixing, and is applicable to different types of steel bars. At the same time, it effectively solves the problem of difficulty in detachment caused by gravity deformation after steel bar hoisting. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] The following is combined with Figure 1-5 This invention describes a specific embodiment of a liftable precast beam reinforcement 4 binding frame, comprising two sets of longitudinal reinforcement fixing mechanisms 1 and two sets of transverse reinforcement fixing plates 2, forming a rectangular structure for easy assembly and welding. Several reinforcement bars 4 are mounted between the two sets of longitudinal reinforcement fixing mechanisms 1, which can also be 4 rings of reinforcement bars, angle steel, etc., as long as they are steel products with the same plane structure. Several fixing parts are provided on the transverse reinforcement fixing plates 2 to fix the reinforcement bars 4 mounted on the transverse reinforcement fixing plates 2. Several lifting mechanisms 3 are provided between the two sets of transverse reinforcement fixing plates 2 to lift the reinforcement bars 4 to detach them from the equipment.

[0019] Beneficially, the longitudinal reinforcement fixing mechanism 1 includes two sets of staggered fixing plates 11, which are staggered and abut against each other. The longitudinal reinforcement fixing mechanism 1 is provided with several fixing grooves 112, which are arranged in a straight line array on one side of the staggered fixing plates 11. Specifically, the fixing grooves 112 are rectangular grooves, V-shaped grooves, or semi-circular grooves, which can be adjusted according to the structure of the steel reinforcement 4.

[0020] Beneficially, the two sets of staggered fixing plates 11 are provided with several fixing blocks 113 on the side away from the contact surface. The number depends on the actual situation. The fixing blocks 113 on the same side are provided with threaded rods 114 in the middle. The threaded rods 114 pass through and are spirally connected to the fixing blocks 113. The two ends of the threaded rods 114 pass through and are rotatably connected to the horizontal rib fixing plates 2.

[0021] Beneficially, the fastener includes a top groove 21, which is located on the mounting side of the horizontal reinforcement fixing plate 2. Two sets of constraint rods 22 are provided in the middle of the top groove 21. The constraint rods 22 are hinged to the middle of the concave side of the top groove 21 through an extension block. A constraint frame 23 is provided between the two sets of constraint rods 22 near the end of the top groove 21. The constraint frame 23 can be an irregular structure, mainly to avoid obstructing the lifting and installation of the reinforcing bar 4. The constraint frame 23 is used to constrain the reinforcing bar 4 between the two sets of constraint rods 22. After the constraint frame 23 falls below the extension block, the constraint rods 22 can expand into a V-shaped structure to facilitate the hoisting of the reinforcing bar 4. The constraint frame 23 abuts against the adjacent constraint rods 22.

[0022] Beneficially, the horizontal rib fixing plate 2 has several bottom grooves 211 on the side away from the top groove 21. The bottom grooves 211 are located on the side of the horizontal rib fixing plate 2 away from the top groove 21. A rotating gear 33 is provided in the middle of the bottom groove 211. The constraint frame 23 is also provided with a lifting rod 24. The lifting rod 24 has several linear array meshing teeth 241 on the side facing the rotating gear 33. The rotating gear 33 meshes with the adjacent meshing teeth 241.

[0023] Beneficially, a rotating rod 35 is provided in the middle of several rotating gears 33. The rotating rod 35 passes through and is fixedly connected to the rotating gears 33. The rotating rod 35 passes through and is rotatably connected to the middle of the horizontal rib fixing plate 2. A rotating motor 351 is provided on the horizontal rib fixing plate 2. The rotating motor 351 drives the rotating rod 35 to rotate.

[0024] Beneficially, the lifting mechanism 3 includes a lifting plate 31, which is disposed between opposite horizontal rib fixing plates 2. The lifting plate 31 has lifting racks 32 at both ends, which mesh with adjacent rotating gears 33. The lifting racks 32 have movable blocks 321 on both sides, and a guide post 322 is provided in the middle of the movable block 321. The guide post 322 passes through and is slidably connected to the movable block 321. The guide post 322 has connecting plates 323 fixedly connected to the horizontal rib fixing plates 2 at both ends.

[0025] Working principle of this utility model: The operator first evenly drops the steel bar 4 into the fixing groove 112 of the staggered fixing plate 11 bracket, and then rotates the threaded rod 114. The staggered fixing plate 11 is driven to move by the abutment of the staggered fixing plate 11 and the connection of the fixing block 113. Then, one of the threaded rods 114 is rotated alone to make the two sets of staggered fixing plates 11 staggered, and the steel bar 4 that has fallen into the fixing groove 112 can be fixed. After the reinforcing bar 4 is placed between the constraint rods 22 in the top groove 21 of the horizontal reinforcement fixing plate 2, the rotating rod 35 is rotated to drive the rotating gear 33 to rotate. The meshing gear 241 drives the lifting rod 24 and the constraint frame 23 to move upward. While the constraint frame 23 moves, it drives the two sets of constraint rods 22 to fold along the hinge direction so that the constraint rods 22 clamp the reinforcing bar 4. Then the rotating rod 35 can be stopped, and the two sets of cross-set reinforcing bars 4 can be tied or welded. After the fixing is completed, the rotating motor 351 drives the rotating rod 35 to rotate in the opposite direction. Under the action of the rotation, the rotating gear 33 drives the lifting rod 24 to fall, causing the two sets of constraint rods 22 to expand into a V-shaped structure without the constraint of the constraint frame 23. At the same time, it drives the lifting rack 32 on the other side to lift the lifting plate 31 along the guide column 322 to guide the moving block 321. The horizontal rib fixing plate 2 and the misaligned fixing plate 11 of the fixed structure are removed from the whole structure. This can avoid the difficulty of separation caused by the gravity deformation of the membrane frame during the hoisting of the structure. At the same time, it is suitable for fixing different steel bars 4 or steel plates, steel rings and other structures.
