[0002] With the rise of the construction industry, my country has become the country with the largest number of super high-rise buildings or the fastest growing number of super high-rise buildings. As a representative building in a city, super high-rise buildings are the weather vane of the city. Generally, super high-rise buildings are located in the core area, which leads to the characteristics of large construction volume, long construction period and small construction site. In order to ensure the continuity of concrete pouring and reduce the frequency of repeated dismantling and modification of pump pipes, climbing concrete placing cranes are often used in the existing construction process.

[0003] Climbing concrete placing machines include floor climbing concrete placing machines, mobile concrete placing machines and elevator shaft climbing concrete placing machines. In the selection process of various climbing concrete placing machines, floor climbing concrete placing machines have advantages over mobile concrete placing machines, such as large spreading radius and independent climbing after one installation. Compared with elevator shaft climbing concrete placing machines and mobile hydraulic concrete placing machines, floor climbing concrete placing machines are convenient and flexible in the selection of installation locations and are not restricted. Therefore, floor climbing concrete placing machines are often used in super high-rise buildings. The basic principle of the application of floor climbing concrete placing machines is to first determine the height of the tower body of the floor climbing concrete placing machine and the radius covered by the boom through overlay, climbing planning and blind spot verification. After the determination, the climbing frame, tower body, boom assembly and delivery pump pipe are assembled in sequence, and finally debugged and put into use. Hydraulic transmission rods are required during the climbing process, and this cycle is carried out to achieve dynamic conversion of different floors.

[0004] However, the difficulty in installing the floor climbing concrete placing boom is that when installing the floor climbing concrete placing boom, a climbing frame, a tower body, an arm assembly and a conveying pump pipe are spliced, and the tower body is heavy and long, so it is very easy for the climbing frame and the tower body of the floor climbing concrete placing boom to tilt during the splicing process, resulting in collisions between the tower body of the floor climbing concrete placing boom and concrete components, steel components between two adjacent floors, and tower cranes, and then it is very easy for the connection effect to be unstable, which causes the climbing of the floor climbing concrete placing boom to affect the structural safety.

[0078] The present application also discloses a method for installing a floor climbing concrete placing boom, using an installation assembly of the floor climbing concrete placing boom, the method comprising the following steps:

[0079] S1. Preserve holes on the floor slab a.

[0080] S2. Install the climbing frame body 1 at the reserved holes on the floor slab a.

[0081] S3, installing the material placing boom 2 on the ground.

[0082] S4, installing the concrete conveying mechanism 3 on the concrete placing boom 2.

[0083] S5. Debug the whole machine.

[0084] Specifically, preparations are required before installation. The plane position is determined and marked by superimposing the structural drawings using CAD software. Then, climbing planning and collision detection are carried out through BIM modeling combined with tower cranes and steel components to determine the installation height and effective radius, and the HGY32 model is selected.

[0085] During installation, a standardized wooden template is used to reserve the hole size, and it is placed accurately at the reserved hole location. Two reinforcing steel bars with the same diameter as the floor reinforcement are set around the hole, extending out to 1 / 2 of the hole width from the edge of the hole.

[0086] The climbing frame of the floor climbing concrete placing boom has two layers. The upper frame mainly bears the horizontal load, and the lower frame bears the horizontal load and the vertical load of the whole machine. Φ48×3mm disc buckles are selected for support. Before erection, load verification is performed based on the maximum bending moment, maximum horizontal force, vertical force, and torque data. The maximum spacing of the frame uprights is calculated to be 900mm*900mm.

[0087] According to the effective lifting radius of the tower crane, a suitable stockpile yard is selected in advance for integrated assembly and lifting. The three tower sections can be assembled on the ground first, and after the ladder, concrete delivery pipe, tower platform and other components are assembled, the whole tower can be lifted and installed on the base frame.

[0088] After the tower body is installed, a theodolite is used to check the verticality of the tower body to the horizontal ground, and the allowable deviation is no more than 20mm.

[0089] Install the upper platform to the upper slewing support on the ground, install the connecting buckle between the railings, and then hoist the upper and lower slewing supports and the rear section of the boom onto the tower body; connect the lower support to the tower body with a connecting pin, insert the split pin, and fix the connecting pin; hoist the front section of the boom, connect the front and rear sections of the boom, fix them with bolts, and connect the hydraulic pipelines.

[0090] When assembling the tower body, upper and lower supports and concrete placing boom, a part of the concrete conveying pipe (including straight pipe and curved pipe) has been fixed to the corresponding parts and connected with pipe joint clamps.

[0091] The concrete delivery pipe between the concrete placing boom and the upper support is connected through a 90° elbow. The concrete delivery pipe on the tower body is directly connected to the elbow leading out of the lower support. A rubber sealing ring should be installed before connection.

[0092] After installation, the structural parts, concrete delivery pipelines, hydraulic system, and electrical system must be thoroughly checked before a test run can be carried out; the test operation should be carried out according to the operating procedures, and all actions should be performed at a low speed at the beginning; during operation, check that the hydraulic system pressure should be within the normal working pressure range and not greater than 20Mpa.

[0093] Optimize the assembly method of the concrete placing boom: According to the effective lifting radius of the tower crane, select a suitable stockpiling site in advance, integrate and install the concrete placing boom tower body, ladder, concrete delivery pipe, tower body platform and other components that are installed in sections to speed up the installation cycle.

[0094] BIM modeling enables collision detection: BIM modeling is used to plan the climbing of the concrete placing boom installation, verify the safe distance from steel components such as the tower crane boom, steel columns and steel plate shear walls, resolve the collision risks caused by traditional installation methods, and improve safety during construction.

[0095] CAD operation of floor plan overlay: by overlaying all floor structure plan drawings, select the reserved openings that have no impact on the structural parts to ensure the normal climbing of the concrete placing boom; accurately locate the plane position and effective radius of the concrete placing boom to reduce the blind area of ​​casting.
