Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for constructing ALC exterior wall panels and main structures on the same floor. Background Technology

[0002] Against the backdrop of high-quality development and comprehensive transformation and upgrading in the construction industry, new industrialization, represented by prefabricated buildings, is rapidly advancing, and prefabricated partition wall technology is being widely applied to infill walls in secondary structures of buildings. Autoclaved aerated concrete (ALC) partition wall panels, as a common prefabricated partition wall technology, possess unique advantages such as light weight, high strength, fire resistance, waterproofing, environmental friendliness, and convenient and efficient construction. They are not only widely used in interior partition walls but are also gradually replacing masonry exterior walls, improving the construction efficiency of secondary structures in buildings.

[0003] However, existing prefabricated ALC exterior wall panels are inserted a second time after the main structure is completed. For example, Chinese patent CN115822126A discloses an ALC panel structure and installation method for high-rise building exterior walls. The construction method involves setting limiting angle steel and flat steel tie rods on the exterior side of the structural beams and slabs, and then installing the ALC exterior wall panels above the limiting angle steel and flat steel tie rods. However, in the aforementioned patent, the installation of the ALC exterior wall panels is carried out after the main structure is completed. This construction method affects the construction sequence, requires additional edge protection facilities, and requires additional angle steel and hook bolts to connect the ALC exterior wall panels to the concrete. The failure to insert the secondary structure in advance affects the construction period, increases construction costs, and the secondary insertion of ALC exterior wall panels after the main structure is completed poses a high risk of construction safety due to working at heights near edges.

[0004] Chinese patent CN115387502B discloses a construction system and method for prefabricated partition walls and main structures built on the same floor. The method involves reserving an installation area on the main wall structure for the prefabricated partition wall panels, with the top of the installation area open. The same-floor reinforcement system includes an aluminum formwork support system and a reinforcement system. The aluminum formwork support system supports the inner and outer sides of the main wall structure, and the reinforcement system fixes the aluminum formwork support system and the prefabricated partition wall panels after they are positioned in the installation area. However, this patent uses L-shaped pipe clamps and anchor bolts to connect the ALC partition wall panels to the upper cast-in-place concrete beams, and uses diagonal bracing to fix the partition wall panels on both sides. This method is not suitable for the same-floor construction of ALC exterior wall panels and main structures, and the ALC partition wall panels do not form a reliable connection with the cast-in-place concrete walls on both sides, increasing the risk of future water leakage. Utility Model Content

[0005] The purpose of this utility model is to provide an ALC exterior wall panel and main structure co-construction device to solve the problems in the existing technology, such as the need for secondary insertion construction for the installation of prefabricated exterior partition walls, long construction period, high construction cost, high risk of working at heights and near edges, and water leakage at the joint between ALC exterior wall panels and concrete walls.

[0006] The technical solution of this utility model is as follows: This utility model is a construction device for ALC exterior wall panels and main structure on the same floor. Its special feature is that the construction device for ALC exterior wall panels and main structure on the same floor includes ALC exterior wall panels and aluminum alloy templates. Aluminum alloy templates are set on the inner and outer sides of the ALC exterior wall panels. Screw holes are set on the aluminum alloy templates. Screw holes are set on the ALC exterior wall panels at the corresponding screw holes. The ALC exterior wall panels and aluminum alloy templates are fixed together by tie rods and back ribs. Double rows of staggered reinforcing bars are set on the bottom and sides of the ALC exterior wall panels.

[0007] Furthermore, in the double-row staggered reinforcement, the diameter of the reinforcement is φ6, the installation depth is 100mm, and the exposed length is 200mm.

[0008] Furthermore, side aluminum alloy templates are installed on both sides of the ALC exterior wall panel.

[0009] Furthermore, steel stirrups are installed at the bottom of the ALC exterior wall panels.

[0010] Furthermore, there are multiple screw holes arranged symmetrically with a spacing of 600mm, and multiple corresponding screw prongs.

[0011] Furthermore, double-sided adhesive tape is applied to the joints between the aluminum alloy formwork and the ALC exterior wall panels.

[0012] This utility model provides a construction device for ALC exterior wall panels and main structure on the same floor. By setting reserved double-row staggered reinforcing bars on the contact surface between the ALC exterior wall panel and the cast-in-place concrete, it is formed by casting the ALC exterior wall panel and the cast-in-place concrete of the main structure in one go, forming a rigid connection. This solves the problems of ALC exterior wall panels needing to be installed in two stages, long construction period, high risk of working near the edge, and poor joint quality. It ensures reliable connection between adjacent components, making the overall performance of the structure equivalent to that of a cast-in-place structure. Moreover, this construction device can be used to complete the construction on the attached lifting scaffold along with the main structure, which is safe and convenient. Attached Figure Description

[0020] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below mainly take the ALC exterior wall panel at the window sill opening as an example. This drawing is only one embodiment of this utility model. For the entire ALC exterior wall panel, similar contact surface rebar installation, rebar stirrups, combined formwork, and concrete pouring methods can also be adopted to achieve the same-layer construction of the entire ALC exterior wall panel. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0021] See Figures 1 to 5 This utility model provides a construction device for ALC (Aluminum Alloy Concrete) exterior wall panels and the main structure on the same floor, including an aluminum alloy template 1, an ALC exterior wall panel 2, and a same-floor construction reinforcement device. The ALC exterior wall panel 2 has a portion of its side reinforced with the aluminum alloy template 1, which has pre-drilled bolt holes spaced 600mm apart. Corresponding bolt holes are provided on the ALC exterior wall panel 2. The aluminum alloy template 1 and the ALC exterior wall panel 2 are fixed together with tie rods 3 and back braces 4. Double-row staggered reinforcing bars 5 are provided on the side and bottom contact surfaces of the ALC exterior wall panel 2 and the cast-in-place concrete wall 6. Reinforcing stirrups 7 are installed below the ALC exterior wall panel 2, with their height matching the height of the cast-in-place concrete wall 6 below the ALC exterior wall panel 2. Side aluminum alloy templates 8 are provided on both the left and right sides of the ALC exterior wall panel 2. Double-sided adhesive is applied to the joints between the aluminum alloy template 1 and the ALC exterior wall panel 2. To prevent grout leakage during concrete pouring.

[0022] This utility model ensures that the ALC exterior wall panel 2 is constructed on the same floor as the main structure. By setting a reserved double-row staggered reinforcing bar 5 at the contact surface between the ALC exterior wall panel 2 and the cast-in-place concrete, it is cast in one go with the cast-in-place concrete of the main structure to form a rigid connection. This solves the problems of the ALC exterior wall panel requiring secondary interlocking construction, long construction period, high risk of working near the edge, and poor joint quality. It ensures a reliable connection between adjacent components, making the overall performance of the structure equivalent to that of a cast-in-place structure. Moreover, this construction device can be used to complete the construction on the attached lifting scaffold along with the main structure, which is safe and convenient.

[0023] This utility model provides a construction device for ALC exterior wall panels and main structure on the same floor. The construction process is as follows: measurement and layout → binding of steel bars for adjacent cast-in-place concrete walls and installation of side aluminum alloy formwork → fabrication of ALC exterior wall panels and steel stirrups → installation of ALC exterior wall panels and aluminum alloy formwork → threading tie rods, installing back bracing for reinforcement, and pouring concrete → sealing and waterproofing of tie rod holes.

[0024] Specifically, it includes the following steps:

[0025] 1) Tie the reinforcing steel of the cast-in-place concrete wall 6 adjacent to the ALC exterior wall panel 2 and install the side aluminum alloy formwork 8; the last aluminum alloy formwork 1 connected to the ALC exterior wall panel 2 is installed synchronously with the ALC exterior wall panel formwork 2.

[0026] 2) According to the dimensions of the exterior wall, cut the ALC exterior wall panel 2 into pieces. Insert double-row staggered steel bars 5 into the contact surface between the ALC exterior wall panel 2 and the cast-in-place concrete wall 6. The steel bar can be installed using the leftover steel bar material on site. The steel bar diameter is φ6, the installation depth is 100mm, and the exposed length is 200mm.

[0027] In the steel bar processing shed, the steel bar stirrups 7 are processed centrally using the steel bar scraps. The steel bar diameter is φ6 and the height is consistent with the cast-in-place concrete wall 6 under the ALC outer wall panel 2.

[0028] 3) Place the steel stirrups 7 inside the cast-in-place concrete wall 6 below the ALC exterior wall panel 2 to temporarily fix the ALC exterior wall panel 2;

[0029] 4) Place ALC exterior wall panel 2, install aluminum alloy template 1, and drill holes in ALC exterior wall panel 2 according to the reserved screw hole positions;

[0030] 5) Adjust the verticality of ALC exterior wall panel 2, insert tie rods 3, install back ribs 4 to achieve final reinforcement, pour concrete, so that ALC exterior wall panel 2 and cast-in-place concrete structure form an "equivalent cast-in-place" whole.

[0031] 6) Before the attached lifting scaffold is lifted, use cement mortar or precast plain concrete cones to seal the screw holes;

[0032] In addition, after the ALC exterior wall panels and the main structure are installed on the same floor, they should be inspected and approved before construction can continue. During use, the installation should be regularly inspected and maintained. Special attention should be paid to checking each connection node, the verticality and flatness of the aluminum alloy formwork and ALC exterior wall panels, and whether the installation is loose.
