Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to an aluminum formwork-matched cantilevered external frame and a construction method for a full concrete exterior wall structure. Background Art

[0002] At present, the main structure of the house is constructed with aluminum alloy formwork. The design optimization usually optimizes the structure into a full shear wall exterior wall structure. When using cantilevered steel pipe external frame for construction, it is easy for the cantilevered I-beam to penetrate the aluminum formwork and the connection between the external frame wall parts and the shear wall structure are two frequently encountered technical problems.

[0003] A Chinese patent with authorization announcement number CN113090025B discloses a method for constructing a cantilevered external frame using an aluminum formwork for an all-concrete external wall structure, which includes the following process flows: design of aluminum formwork, positioning and laying out of I-beams and pre-embedding of anchor rings on the Nth layer, installation of I-beams and shaped extruded panels, production and installation of concave aluminum-plastic panels, erection of external scaffolding on the N+1th layer, installation of aluminum formwork for shear walls or bay windows and pre-embedding of conical sleeves, construction of the main structure on the N+1th layer, removal of wall formwork and removal of conical sleeves, installation of wall ties on the N+1th layer, construction of the main structure on the N+2th layer, installation of I-beam inclined steel wire rope pull rings and walls, pre-embedding of conical sleeves, pulling of I-beam inclined steel wire ropes, erection of the N+2th layer cantilevered external frame, installation of wall ties, erection of the external frame on the N+3th layer, construction of the main structure, installation of wall ties, and a cycle upwards, layer by layer, to complete the entire construction.

[0004] However, the inventor believes that the above-mentioned related technologies have the following defects. In the actual process of erecting the cantilever external frame, scaffolding is needed to facilitate construction workers to carry out construction operations on the outside of the wall. Especially when positioning and laying out the I-beams, installing the pull rings of the I-beam inclined wire ropes, and pulling the I-beam inclined wire ropes, workers are required to climb on the scaffolding to operate manually. The traditional cantilever external frame has a small available space. In order to complete the above-mentioned construction operations, the workers can only go back and forth multiple times, which not only reduces the construction efficiency, but also significantly increases the construction risks of the workers during the construction process.

[0053] In the second aspect, the embodiment of the present application discloses a construction method for aluminum formwork in cooperation with a cantilever external scaffold for a fully concrete exterior wall structure.

[0054] A construction method for aluminum formwork in cooperation with a cantilever external scaffold for a fully concrete exterior wall structure includes:

[0055] Aluminum formwork design, positioning and setting out of the first-layer I-beam and embedding of anchor rings, installation of I-beams and standardized extruded polystyrene boards, production and installation of concave aluminum plastic boards; erection of the second-layer scaffold, installation of aluminum formwork for shear walls or bay window walls and embedding of tapered sleeves, construction of the second-layer main structure, removal of wall formwork and removal of tapered sleeves, installation of the second-layer connecting wall members; installation of the mounting seat 2 and the mounting rod 5, and winding and installation of the steel wire rope 22; construction of the third-layer main structure, driving the driving pedal to deflect, and limiting the position of the driving pedal through the limiting plate to pull the I-beam inclined steel wire rope 22, embedding of tapered sleeves, installation of the third-layer cantilever external scaffold and connecting wall members; erection of the fourth-layer external scaffold, construction of the main structure, installation of connecting wall members; circular construction layer by layer upward until all construction is completed.

[0056] The implementation principle of the aluminum formwork cooperating with the cantilever external scaffold and the construction method for the all-concrete exterior wall structure in the embodiments of the present application is as follows:

[0057] During the actual use process, after the steel wire rope 22 is installed on the installation roller 21 and the reversing wheel 3, the staff climbs on the scaffold. At this time, step on the driving pedal with the foot, and the driving pedal drives the installation roller 21 to move away from the reversing wheel 3, so as to stretch the I-beam stay steel wire rope 22. As the driving pedal deflects, the limiting rod 12 abuts against the limiting plate. As the driving pedal further deflects, the limiting plate deflects into the limiting groove 44 under the action of the limiting rod 12, and the limiting rod 12 enters the limiting groove 44. At this time, the limiting plate is separated from the limiting rod 12, and the limiting plate deflects under the action of the second elastic member 47 and abuts against the edge, and at this time, the opening of the limiting groove 44 can be closed, so as to prevent the limiting rod 12 from disengaging from the limiting groove 44. At this time, the stretching of the steel wire rope 22 can be completed. The whole process is simple and convenient to operate. Only the staff needs to complete the stepping action to complete all the operations, effectively improving the construction efficiency. And because the operation actions of the construction personnel are reduced, the purpose of reducing the construction risk of the construction personnel is achieved;

[0058] During the stretching process, according to the different construction positions, the specific stretching positions of the steel wire rope 22 are also different. At this time, by driving the slider 52 to move in the chute 51 through the driving component 6, the position of the reversing wheel 3 on the installation rod 5 can be adjusted to make different position adjustments for different stretching positions. The operation is convenient and fast, and has good practicability.

[0059] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
