Description

Technical Field

[0001] This utility model relates to the field of formwork hoisting technology, specifically to a formwork hoisting device. Background Technology

[0002] In cast-in-place concrete sections such as precast beams for water conservancy and road transportation, combined steel formwork or large formwork is typically used for erecting and pouring concrete to ensure construction progress or improve the appearance quality of the concrete. In existing construction techniques, after the concrete has reached its required strength, when removing the formwork, to ensure the formwork's center of gravity and construction safety, the back supports of the formwork are usually removed first, followed by the formwork itself. The formwork and back supports are then reinstalled for the next section of construction. This process requires repeated installation and removal of the formwork and supporting back supports. For some suspended sections, manual installation and removal pose significant safety risks. Furthermore, the overall construction requires substantial manpower and equipment, increasing construction costs.

[0003] Chinese patent document with application number 202122136156.0 discloses a precast box girder formwork hoisting device, which includes a hoisting plate, a hoisting ring connected to the top surface of the hoisting plate, and a vertically extending baffle provided near the edge of the bottom surface of the hoisting plate. The bottom of the hoisting plate and one side of the baffle form a placement space for placing the precast box girder formwork. Two sets of suspension components are horizontally spaced on the side of the baffle facing the placement space. A balance plate is provided below the baffle and the suspension components. The suspension components include a hanging plate, a limit plate connected to the end of the hanging plate away from the baffle, an inclined support rod provided between the bottom surface of the hanging plate and the baffle, and a pressing block slidably connected to the top surface of the hanging plate. A first push rod is rotatably connected to the side of the pressing block facing the baffle. The end of the first push rod away from the pressing block passes through the baffle and is connected to a first handle. This precast box girder formwork hoisting device has the following shortcomings: 1) The longitudinal rods and supports of the shaped template are lifted by a pair of horizontally spaced hanging plates, and the longitudinal rods and supports are clamped by limiting plates and pressing plates. The structure is complex and the operation is inconvenient. 2) The hanging plate and baffle are fixed as one piece, and the distance between them and the hanging plate is fixed, which makes it difficult to meet the hoisting requirements of different templates and results in poor adaptability; 3) The stability is poor as it is lifted by only one ring on the hanging plate. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a template hoisting device that is simple in structure, easy to operate, highly adaptable, and stable.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A formwork hoisting device includes a support frame and a hanger fixedly connected in an L-shape. The support frame has multiple horizontal rows of first mounting parts arranged at intervals along the length of the support frame. The hanger has multiple horizontal rows of second mounting parts arranged at intervals along the length of the hanger. The formwork hoisting device also includes at least two horizontal rows of hooks and at least two horizontal rows of lifting rings. Each horizontal row of hooks is selectively installed on a horizontal row of first mounting parts and extends into the inside of the support frame. Each horizontal row of lifting rings is selectively installed on a horizontal row of second mounting parts and extends into the upper side of the hanger.

[0006] As a further improvement to the above technical solution: The first mounting part includes at least two spaced-apart first mounting holes, and the hook is provided with at least two fasteners, each of which is inserted into the mounting hole in a corresponding manner.

[0007] The fastener is a pin or a bolt.

[0008] The second mounting part is a socket, and the lifting ring is provided with a locking element, which passes through the socket.

[0009] The locking element is a locking pin or a bolt.

[0010] The length direction of the hanger is perpendicular to the length direction of the stop.

[0011] The baffle includes two vertical baffles and a connecting rod between the two vertical baffles. The top of the vertical baffles is fixedly connected to the hanger. The first mounting part of each horizontal row of the first mounting part is respectively located on each vertical baffle.

[0012] The hanger includes two longitudinal hangers and a horizontal bar connecting the two longitudinal hangers. The top ends of the two vertical bars are fixedly connected to one end of the two longitudinal hangers, and the second mounting part of each horizontal row of the second mounting part is respectively provided on each longitudinal hanger.

[0013] The top of the longitudinal suspension rod is provided with a suspension plate, and the second mounting part is provided on the corresponding suspension plate.

[0014] Both the retaining frame and the hanger are steel frames.

[0015] Compared with the prior art, the advantages of this utility model are: In use, the formwork hoisting device of this utility model involves attaching the hooks of a gantry crane to each lifting ring via lifting ropes. The gantry crane is then controlled to lift the formwork hoisting device off the ground. The position of the formwork hoisting device is adjusted so that the back ribs of the formwork are positioned on the hooks, and then the gantry crane is controlled to lift the formwork. Firstly, the formwork is hoisted by inserting at least two horizontal rows of hooks into the back ribs of the formwork, using a lifting and clamping method relative to a pair of hanging plates, resulting in a simple structure and convenient operation. Secondly, each horizontal row of hooks is selectively installed on a first mounting part of a horizontal row, meaning the distance between the hooks and the hanger can be adjusted, meeting the hoisting requirements of different formwork types and offering excellent adaptability. Thirdly, each lifting ring forms multiple lifting points, providing better stability when hoisted relative to a single ring. Fourthly, each horizontal row of lifting rings is selectively installed on a second mounting part of a horizontal row, allowing adjustment of the rings' position on the hanger to achieve optimal hoisting results.
