Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building construction, and specifically relates to a high-altitude split load type steel corridor and a construction process thereof. BACKGROUND

[0002] With the development of modern buildings towards high-rise and complexity, steel corridors are widely used as a structure connecting two or more high-rise buildings. The steel corridor not only needs to meet the traffic function, but also needs to bear the complex mechanical requirements such as wind load and earthquake action. At present, large-span steel corridors mostly adopt integral hoisting or segmented assembly process, but the construction efficiency and safety become the industry pain points due to the limitation of lifting equipment capacity and site conditions. In recent years, although the fusion of BIM technology and modular construction improves the precision, it still cannot fundamentally solve the problems of high risk of high-altitude operation and high cost of temporary support system. Therefore, a split load type steel corridor is needed to improve the construction efficiency.

An upper connecting end, a lower connecting end and an inclined support connecting end are arranged on the corridor pre-installation part.

Embed the suspension supports in the shear walls on both sides of the building, leaving the support blocks exposed. Place multiple sets of main load-bearing frames side by side on the ground, and place two sets of secondary load-bearing frames at the ends on the left and right sides, so that the slots of the two sets of secondary load-bearing frames align with the slots of the main load-bearing frames. Insert the connecting crossbar into the main and secondary load-bearing frames and center them. S2, slide the first reinforcement frame and the second reinforcement frame so that the sliding end of the first reinforcement frame is away from the sliding end of the second reinforcement frame, and insert the first reinforcement frame and the second reinforcement frame into the reinforcement slots opened by the corresponding connecting cross bars respectively. After completing the insertion and connection of the first reinforcement frame, the second reinforcement frame and the reinforcement slots, pour concrete into the reinforcement slots and the first casting trough through the third casting trough, so that after the concrete solidifies, the first reinforcement frame and the connecting cross bar, and the second reinforcement frame and the connecting cross bar are connected, thereby fixing the multiple groups of main load-bearing frames between the two groups of secondary load-bearing frames, and thus completing the assembly of the split main load-bearing frames; S3.

Place multiple sets of main load-bearing frames (2) side by side on the ground, and place two sets of auxiliary load-bearing frames (3) at the ends on the left and right sides, so that the slots of the two sets of auxiliary load-bearing frames (3) and the main load-bearing frames (2) correspond. At this time, insert the connecting crossbar (5) into the main load-bearing frames (2) and the auxiliary load-bearing frames (3), and center them. S2, sliding the first reinforcement frame (601) and the second reinforcement frame (603) so that the sliding end of the first reinforcement frame (601) is away from the sliding end of the second reinforcement frame (603), and the first reinforcement frame (601) and the second reinforcement frame (603) are respectively inserted into the reinforcement slots (605) opened by the corresponding connecting cross bars (5). After completing the insertion and connection of the first reinforcement frame (601), the second reinforcement frame (603) and the reinforcement slots (605), concrete is poured into the reinforcement slots (605) and the first casting trough (602) through the third casting trough (606). After the concrete solidifies, the first reinforcement frame (601) and the connecting cross bars (5) and the second reinforcement frame (603) and the connecting cross bars (5) are connected, thereby fixing the multiple groups of main load-bearing frames (2) between the two groups of secondary load-bearing frames (3), and completing the assembly of the split main load-bearing frames (2); S3, after completing the insertion of the first reinforcement frame (601) and the second reinforcement frame (603) and fixing them to the connecting crossbar (5), insert the prefabricated casting block (703) into the interior of the sliding groove (702) through the installation groove (701), and pour concrete inside the prefabricated casting block (703). After the pouring is completed, slide it between the second reinforcement frame (603) and the first reinforcement frame (601), and set multiple groups of prefabricated casting blocks (703). After the sliding groove (702) is filled, the concrete inside the prefabricated casting block (703) is solidified. At this time, the connecting crossbars (5) on both sides are supported by the first reinforcement frame (601) and the second reinforcement frame (603) and the solidified multiple groups of prefabricated casting blocks (703), thereby improving the strength of the main load-bearing frame (2), the auxiliary load-bearing frame (3) and the connecting crossbar (5) after assembly; S4, and by setting up multiple groups of main load-bearing frames (2), secondary load-bearing frames (3) and assembly blocks of connecting cross bars (5), the length of which can meet the length of the buildings on both sides, using a crane to set the first group of assembly blocks between the buildings on both sides, and hoisting the assembly blocks from the middle to both ends, each group of assembly blocks is connected by bolts, and a temporary stabilizing cable is immediately tensioned after each group of assembly blocks is installed. When the assembly blocks are connected to the buildings, multiple groups of support blocks (802) fixed outside the suspension support (1) are inserted into the main load-bearing frame (2), so that the first pouring hole (801) and the second pouring hole (803) are connected; S5. Pour concrete into the first pouring hole (801), so that the concrete is poured into the first pouring hole (801) through the first pouring hole (801) and the second pouring hole (803), and poured into the reinforcement groove (806) through the conveying hole (805). When the concrete fills the support block (802) and solidifies, the solidified concrete can connect the support block (802) and the main load-bearing frame (2), thereby improving the strength of the corridor after installation.
