Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a Bailey frame-based high-support formwork support system and a construction method. Background Art

[0002] Bailey frame is a support system commonly used in high-rise formwork to support and fix concrete formwork and support rods. It usually consists of horizontal brackets, columns, adjustment screws and connectors, providing an adjustable support framework so that the formwork can adapt to different heights and layout requirements.

[0003] However, there are still some defects to a certain extent: when binding the upper chord and the distribution beam, it is necessary to put the U-shaped clamp on the distribution beam and then fix it through the bottom.

[0016] The construction method of the high-support formwork support system based on Bailey frame includes the following steps:

[0017] Step 1: First, pour the cement base, install the steel pipe, and then fix it with chemical bolts. Then, install the Bailey plate between the two steel pipes. There are fixing devices on the upper and lower sides of the Bailey plate. Pull the pull rod outward to snap it into the groove on the back. When the pull rod is pulled, the connecting rod 1 and the movable block will move to the right and squeeze the spring 1. When the movable block moves to the right, it will pull the fixing rod 1 into the fixing device.

[0018] Step 2: Place the Bailey plate between the two steel pipes, align the fixing rod with the hole inside the steel pipe, and push the pull rod upward. When the pull rod reaches the top, the spring will rebound after a while. Push the movable block to the left and push the fixing rod into the groove inside the steel pipe to secure it.

[0019] Step 3: Then install the unloading device to the top of the steel pipe and then turn the handle to drive the connecting ring to rotate and squeeze the moving block to control the height. Install the I-beam above the unloading device and then install the Bailey frame on the ground. Connect the connecting plate 2 and the connecting plate 1 on both sides of the Bailey frame, and then fix the connecting plate 2 and the connecting plate 1 with the fixing bolt 1. Then install the support plate on the left side of the Bailey frame and fix the fixing bolt 2 to the Bailey frame with the fixing bolt 2.

[0020] Step 4: After the installation is completed, use a crane to lift the Bailey frame and place it on the I-beam. Then place the distribution beam on the top of the Bailey frame and fix the Bailey frame and the I-beam distribution beam through the clamping mechanism. First, press the connecting rod 2 downward to push the inside of the fixing rod 2 together and squeeze it together with the baffle. The spring 2 will retract the fixing rod 2 into the inside.

[0021] Step 5: Then extend the clamping mechanism through the distribution beam to the bottom of the upper chord and then loosen the spring 2 of the connecting rod 2, and start to rebound to push the baffle and the connecting rod 2 upward. When the baffle is upward, it will squeeze the bottom of the fixed rod 2 to extend it outward, and then rotate the fixing ring so that it can be threaded downward to clamp the distribution beam and the upper chord with the fixed rod 2. If it is difficult to rotate the fixing ring, you can use a control tool to sleeve it on the outside of the support rod to rotate it.

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

[0023] The present invention presses the connecting rod 2 downward to push the fixing rod 2 closer to the inside and squeezes the spring 2 together with the baffle. When the fixing rod 2 is retracted into the inside, the clamping mechanism is extended through the distribution beam to the bottom of the upper chord rod, and then the connecting rod 2 is released. The spring 2 starts to rebound and pushes the baffle and the connecting rod 2 upward. When the baffle is upward, it squeezes the bottom of the fixing rod 2 to extend it outward, and then the fixing ring is rotated to clamp the distribution beam and the upper chord rod downward through the thread of the fixing rod 2. The distribution beam and the upper chord rod can be quickly fixed with simple operation and high work efficiency.

[0024] The present invention is provided with a fixing device, and the pull rod is pulled outward to clamp it into the groove on the back. When the pull rod is pulled, the connecting rod 1 and the movable block will be driven to move to the right and squeeze the spring 1. When the movable block moves to the right, the fixing rod 1 will be pulled into the fixing device, and then the fixing rod 1 will be aligned with the hole on the inner side of the steel pipe. Then the pull rod is pushed upward. After the pull rod is pushed to the top, the spring 1 will start to rebound after a while, pushing the movable block to the left and then pushing the fixing rod 1 into the groove inside the steel pipe for fixing. The Bailey plate can be quickly fixed between the two steel pipes. BRIEF DESCRIPTION OF THE DRAWINGS

6. A construction method for a Bailey frame-based high-rise formwork support system according to claim 4, characterized in that: The following steps are involved: Step 1: First, pour the cement base (1), install the steel pipe (101), and then use chemical bolts (102) to fix it. Then, install the Bailey plate (6) between the two steel pipes (101). Fixing devices (2) are set on the upper and lower sides of the Bailey plate (6). Pull the pull rod (206) outward to snap it into the groove on the back. When pulling the pull rod (206), it will drive the connecting rod 1 (204) and the movable block (202) to move to the right and squeeze the spring 1 (203). When the movable block (202) moves to the right, it will pull the fixing rod 1 (201) into the fixing device (2); Step 2: Then place the Bailey plate (6) between the two steel pipes (101), then align the fixing rod (201) with the hole inside the steel pipe (101), and then push the pull rod (206) upward. After pushing the pull rod (206) to the top, the spring (203) will start to rebound, push the movable block (202) to the left, and then push the fixing rod (201) into the groove inside the steel pipe (101) to fix it; Step 3: Then install the unloading device (5) to the top of the steel pipe (101) and then twist the handle (503) to drive the connecting ring (504) to rotate the extrusion moving block (501) to control the height, install the I-beam (103) above the unloading device (5) and then install the Bailey frame (4) on the ground, connect the connecting plate 2 (404) and the connecting plate 1 (403) on both sides of the Bailey frame (4), and then fix the connecting plate 2 (404) and the connecting plate 1 (403) by fixing bolt 1 (405), and then install the support plate (406) on the left side of the Bailey frame (4) and then fix the fixing bolt 2 (408) to the Bailey frame (4) by fixing bolt 2 (408); Step 4: After the installation is completed, use a crane to lift the Bailey frame (4) and place it on the I-beam (103). Then place the distribution beam (104) on the top of the Bailey frame (4). Fix the Bailey frame (4) and the I-beam distribution beam (104) through the clamping mechanism (3). First, press the connecting rod 2 (305) downward to push the fixing rod 2 (307) closer to the inside and squeeze it together with the baffle (309). The spring 2 (310) retracts the fixing rod 2 (307) to the inside. Step 5: Then extend the clamping mechanism (3) through the distribution beam (104) to the bottom of the upper chord (402) and then loosen the spring (310) of the connecting rod (305). The spring (310) starts to rebound and push the baffle (309) and the connecting rod (305) upward. When the baffle (309) moves upward, it squeezes the bottom of the fixing rod (307) to extend it outward. Then rotate the fixing ring (302) so that it can clamp the distribution beam (104) and the upper chord (402) downward with the fixing rod (307) through the thread (306). If it is difficult to rotate the fixing ring (302), you can use a control tool to connect it to the outside of the support rod (303) to rotate it.
