Description

Technical Field

[0001] This application relates to the field of engineering and construction technology, and in particular to a formwork structure for the construction of the main structure of a high-rise building. Background Technology

[0002] Steel platform formwork equipment has become one of the most widely used construction equipment for super high-rise building structures in recent years. Existing steel platform formwork equipment is divided into two types: jacking type and lifting type. Both use an integral steel frame, platform plate, scaffolding system, etc. to provide a closed construction working surface. It makes full use of the strong load-bearing capacity of steel structure. Hydraulic cylinders provide driving force to make the formwork equipment climb upward along the core tube of the super high-rise building. The steel bars required for the construction of the core tube can be stacked on the top working plane of the steel platform formwork equipment. The formwork can be suspended on the supporting main beam of the steel platform formwork equipment, and the concrete can be poured by the concrete placing machine arranged on the steel platform formwork equipment. Therefore, the use of steel platform formwork equipment has greatly improved the construction efficiency and construction level of super high-rise building structures.

[0003] However, in the existing technology, it has been found that when the lower support beam and the upper support beam are raised and lowered alternately by hydraulic rods, manual anchoring is often used for installation. This allows the lower support beam and the upper support beam to be installed alternately, resulting in a long construction time each time, which in turn affects the construction efficiency. Utility Model Content

[0004] The purpose of this application is to provide a formwork structure for the construction of the main structure of a high-rise building, which has the advantages of being able to quickly alternate the formwork mechanism through the connection of connecting blocks and reserved connecting slots, eliminating the time for manual anchoring installation, improving construction efficiency, and solving the problems raised in the prior art.

[0005] The technical solution of the formwork structure for the construction of the main structure of a high-rise building provided in this application is as follows: it includes two main columns, a lower support beam and an upper support beam are provided between the two main columns, a hydraulic rod is fixedly installed on the inner wall of the lower support beam, the output end of the hydraulic rod is fixedly connected to the bottom surface of the upper support beam, and a reserved connection groove is reserved on the side of each main column that is close to each other.

[0006] Limiting grooves are formed on the left and right sides of the lower and upper support beams. A connecting block and two connecting arms are slidably connected to the inner wall of each limiting groove. The side of each connecting block that is close to each other is fixedly connected to the end of the corresponding connecting arm. A dual-axis motor and a fixing block are fixedly installed on the upper surface of both the lower and upper support beams. A threaded rod is fixedly connected to the two output shafts of each dual-axis motor. The outer surface of each threaded rod is threadedly connected to the inner wall of the corresponding connecting arm. Limiting rods are fixedly connected to the left and right sides of each fixing block. The outer surface of each limiting rod is slidably connected to the inner wall of the corresponding connecting arm. Equally spaced limiting blocks are fixedly connected to the upper surface of both the lower and upper support beams. The side of each limiting block that is close to each other is rotatably connected to the end of the corresponding threaded rod. The side of each limiting block that is close to each other is fixedly connected to the end of the corresponding limiting rod.

[0007] By adopting the above technical solution, a lower support beam and an upper support beam are set between the two main columns. During the casting of the main column, a pre-reserved connecting groove is made, and a hydraulic rod is fixed to the lower support beam. The output end of the hydraulic rod is connected to the upper support beam. When the lower support beam is fixed, the hydraulic rod is driven to extend, allowing the upper support beam to rise. Limiting grooves are opened on both sides of the lower and upper support beams, and connecting blocks and connecting arms are slidable within the inner walls of the limiting grooves to limit their movement. A dual-axis motor is installed on the upper surfaces of the lower and upper support beams, and screws are installed at the two output ends of the dual-axis motor. The threaded rod allows the corresponding threaded rod to rotate under the drive of a dual-axis motor. Through the threaded connection between the threaded rod and the connecting arm, the connecting block and the connecting arm can move, allowing the connecting block to enter the corresponding reserved connecting groove. This enables the lower support beam and the upper support beam to be respectively limited to a specified height between the two column bodies. By setting a limit rod connected to the corresponding connecting arm, the limit rod can limit the connecting arm, improving the stability of the connecting block during movement. Through the connection and disconnection of the connecting block and the reserved connecting groove, the formwork mechanism can rise alternately, eliminating the need for manual anchoring installation and significantly improving construction efficiency.

[0008] Preferably, the bottom surfaces of both the lower and upper support beams are fixedly connected to two reinforcing ribs, the upper surface of the upper support beam is fixedly connected to a connecting rod, and the outer surface of the connecting rod is fixedly connected to a support member.

[0009] By adopting the above technical solution, two reinforcing ribs are installed on the bottom surface of the lower support beam and the upper support beam. The reinforcing ribs can improve the support strength of the lower support beam and the upper support beam. A connecting rod is installed on the upper surface of the upper support beam. When the upper support beam rises under the drive of the hydraulic rod, the connecting rod can rise. A support component is set to be fixed to the connecting rod to realize the installation of the support component.

[0010] Preferably, the top end of the connecting rod is fixedly connected to a lower platform, and the bottom surface of the lower platform is fixedly installed on the upper surface of the support member.

[0011] By adopting the above technical solution, the lower platform is installed at the top of the connecting rod, and the lower platform is fixed to the support component with bolts, thereby supporting the lower platform while further improving the support stability through the support component.

[0012] Preferably, a truss steel platform is fixedly connected to the upper surface of the lower platform, and an upper platform is fixedly connected to the upper surface of the truss steel platform.

[0013] By adopting the above technical solution, the truss steel platform is installed on the upper surface of the lower platform, and an upper platform is set on the upper surface of the truss steel platform to support the upper platform.

[0014] Preferably, the upper surface of the upper platform is fixedly connected to two guardrails, and each guardrail has a slot on the side that is close to the other.

[0015] By adopting the above technical solution, guardrails are installed on the upper surface of the upper platform. The guardrails can protect the front and back of the upper platform and ensure construction safety. Slots are opened on the side of the guardrails that are close to each other to achieve the positioning of the slots.

[0016] Preferably, a limiting component is fixedly installed on the upper surface of the upper platform, and a side guardrail is rotatably connected to the outer surface of the limiting component. The side guardrail has sliding grooves on both the front and back sides.

[0017] By adopting the above technical solution, a limiting component is installed on the upper surface of the upper platform, and a side guardrail is set on the surface of the limiting component. The limiting component and the side guardrail are set as a rotatable connection to realize the limiting of the side guardrail. Slide grooves are opened on the front and back of the side guardrail to realize the positioning of the slide grooves.

[0018] Preferably, a spring is fixedly connected to the inner wall of each groove, and a slider is fixedly connected to the other end of each spring.

[0019] By adopting the above technical solution, a spring is set on the inner wall of the slide to limit one end of the spring, and a slider is installed on the other end of the spring so that the spring can press the slider tightly.

[0020] Preferably, each slider has a fixed rod connected to its opposite side, the outer surfaces of each slider and rod are slidably connected to the inner wall of the corresponding groove, and each rod is adapted to the corresponding slot.

[0021] By adopting the above technical solution, the insertion rod is installed on the side of the slider that is far apart from each other, so as to realize the positioning of the insertion rod. The slider and the insertion rod are connected to the corresponding slide groove to realize the limiting of the slider and the insertion rod. Furthermore, the insertion rod is adapted to the slot, so that after the insertion rod enters the slot, it can lock the side guardrail. The upright side guardrail can protect the left and right sides of the upper platform.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This type of formwork structure for the construction of the main structure of high-rise buildings uses components such as connecting blocks and threaded rods. During pouring, pre-reserved connecting slots are reserved at designated positions on the main column. The dual-axis motor of the lower support beam is started, driving the threaded rod to rotate, causing the connecting arms on both sides to move. At this time, the connecting blocks connect with the reserved connecting slots and lock the lower support beam. After the hydraulic rod is started, the upper support beam is raised, and the connecting blocks on both sides of the upper support beam are placed on the corresponding main column. After the pouring is completed, the connecting blocks of the lower support beam are retracted, and the lower support beam is raised by the retraction of the hydraulic rod. The connecting blocks are then connected with the reserved connecting slots again to lock the lower support beam. This allows the formwork mechanism to rise alternately, eliminating the need for manual anchoring and improving construction efficiency. During construction, the side railings are rotated to stand up. Through the connection between the insert rod and the slider, the insert rod can enter the corresponding slot, thereby locking the side railing. The standing side railings and guardrails can protect the front, back, left, and right sides of the upper platform, reducing the occurrence of safety accidents. Attached Figure Description
