Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a positioning device for interlayer of external wall insulation integrated panel and a construction method. BACKGROUND

[0002] In recent years, in the field of building external wall insulation construction, the interlayer reinforcement of external wall insulation integrated panel has been a key link in construction, and its construction quality directly affects the insulation performance, appearance quality and stability of the overall structure of the building. However, the traditional construction method has many problems in practical application, and it is difficult to meet the high requirements of modern building construction for quality and efficiency.

[0003] There are mainly two kinds of traditional interlayer reinforcement methods for external wall external insulation integrated panel: one is to use primary and secondary beams for reinforcement, and the other is to reinforce after full-paving formwork on the outside of the external wall insulation integrated panel. However, both methods have obvious defects and deficiencies. When using primary and secondary beams for reinforcement, due to the limited support force of the primary and secondary beams, the insulation integrated panel is prone to deformation during construction, especially at the top and root positions of the insulation panel. This deformation will result in the verticality and flatness of the external wall not meeting the standards, seriously affecting the appearance quality and insulation effect of the building. According to actual construction statistics, the traditional technology of using primary and secondary beams for reinforcement is prone to misalignment between layers, with a deviation of 5-10mm, and the qualified rate of verticality and flatness of the external wall is only 70%-80%, which is difficult to meet the high standard requirements of modern building construction. In order to improve this situation, the method of reinforcing after full-paving formwork on the outside of the external wall insulation integrated panel has improved the construction quality to some extent, but at the same time it has brought new problems. This method requires an additional 30%-50% of formwork, resulting in a significant increase in project cost. Moreover, due to the increase in formwork, the construction efficiency is also seriously affected, and the construction period of each layer is extended by 2-3 days, which is extremely disadvantageous to the overall progress and cost control of the building project.

[0004] Therefore, a positioning device for interlayer of external wall insulation integrated panel and a construction method are provided to solve the above problems. SUMMARY

[0005] In order to solve the above-mentioned problems, the present application provides a positioning device for interlayer of external wall insulation integrated panel and a construction method, which can ensure the installation precision of the insulation integrated panel between layers, reduce the use cost of formwork and improve the construction efficiency, to solve the outstanding problems in the traditional technology.

[0006] To achieve the above-mentioned purpose, the present application provides a positioning device for interlayer of external wall insulation integrated panel, comprising a K plate and a connecting assembly;

[0007] The K plate is higher than the structure surface of the layer, and is used to press the upper edge of the lower insulation integrated panel;

[0009] The lower surface of the K-board forms a positioning contact surface with the upper edge of the integrated insulation board.

[0010] Preferably, the connecting components are pins or bolts, which are fixed to the main ribs of the aluminum alloy template to form an integral force-bearing system.

[0011] Preferably, the surface of the K board has anti-slip texture to enhance friction with the insulation board.

[0012] Preferably, the dimensions of the K board are layer height × 200mm × 5mm.

[0017] S2: After the concrete is poured, the K-board is retained, and the lower integrated insulation board is embedded between the K-board and the wall reinforcement, and positioned by the lower surface of the K-board;

[0018] S3: In subsequent processes, K-plates are used as reinforcement supports to complete the overall fixation of the integrated insulation panel and the aluminum mold.

[0019] Preferably, the detailed design of the aluminum alloy formwork in S1 includes pre-simulating the position of the K-board in the BIM model to ensure that it matches the layout of the integrated insulation board and the spacing of the reinforcing bars.

[0020] Preferably, after the concrete is poured in S2, slab K is retained, specifically including:

[0021] When the K-plate is pre-embedded and fixed, it is installed simultaneously with the aluminum formwork of this layer and fixed to the shear wall by tie rods. After the concrete is poured, the K-plate and the structural layer form an integral whole.

[0022] Preferably, in step S2, the lower integrated insulation panel is embedded between the K panel and the wall reinforcement, and positioned by the lower surface of the K panel, specifically including:

[0023] When installing the lower insulation board, use the lower surface of the K board as a positioning reference, and ensure that the upper edge of the insulation board is tightly fitted to the K board.

[0024] Therefore, the application adopts the above-mentioned external wall thermal insulation integrated board interlayer positioning device and construction method, aiming at the reinforcement of the external wall thermal insulation integrated board interlayer, the traditional method is easy to cause the deformation of the upper and root of the thermal insulation board, the verticality and flatness of the external wall do not meet the requirements, and the project cost is high and other problems.

[0051] S2: After concrete pouring, keep the K plate 1, embed the lower thermal insulation integrated board 3 between the K plate 1 and the wall steel bar 4, and position it through the lower surface of the K plate 1;

[0052] Specifically, when the K plate 1 is embedded and fixed, the K plate 1 is installed synchronously with the aluminum formwork of the current layer, fixed by the tensioning screw rod 5 and the shear wall, and the K plate 1 forms a whole with the structure layer after concrete pouring. When installing the lower thermal insulation board, use the lower surface of the K plate 1 as the positioning reference, and make the upper edge of the thermal insulation board closely fit the K plate 1 with a gap of less than or equal to 1 mm. No additional measurement and line laying are needed, and the layer-to-layer misalignment is controlled through physical limiting.

[0053] S3: Use the K plate 1 as a reinforcing fulcrum in the subsequent process to complete the overall fixation of the thermal insulation integrated board and the aluminum formwork.

[0054] In practical application, the operation process of the present embodiment is as follows: familiarize yourself with the drawings, template deepening (aluminum formwork pre-positioning thermal insulation integrated board), combine with the structure drawing, and carry out aluminum alloy formwork 7 deepening design, focusing on the interlayer reinforcing method.
