Description

Technical Field

[0001] The present invention relates to the technical field of civil engineering, and more specifically, to a high-precision TCP bell-mouth window and door jamb for exterior decoration of a theme and its construction method. Background Art

[0002] With the higher requirements of theme parks for the themes they present, the shapes of doors and windows are the most complex (such as arched, bell-mouth shapes, etc.), and at the same time, problems such as waterproofing, heat preservation, and airtightness need to be satisfied, which are the difficulties and key points of exterior theme packaging.

[0003] In theme park projects, TCP (theme cement plastering) is one of the commonly used theme packaging practices and is widely applied to various theme packaging projects in the front area of theme parks and landscaping projects in site development.

[0004] In the past, one method was to use a concrete sub-frame for initial positioning and then use TCP for closing the opening. However, when the shape of the opening is complex, it is difficult to support the formwork and the positioning is inaccurate, ultimately affecting the exterior theme shape. Another method is to add a steel sub-frame for positioning and then use TCP for closing the opening. However, the waterproofing of the gap between the steel sub-frame and the wall is the key point and difficulty in construction, and improper treatment is likely to cause water leakage and non-compliance with airtightness requirements.

[0005] Therefore, how to provide a high-precision TCP bell-mouth window and door jamb for exterior decoration of a theme and its construction method is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0029] 4. In the structure of the inner frame jamb module, in addition to the wall waterproofing extending to the window frame or door frame part, an additional side joint waterproofing is added, which effectively ensures the waterproofing effect of the entire joint position and reduces the risk of water leakage and entry of humid air.

[0030] 5. A drip groove is provided on the upper edge of the jamb, which effectively prevents the rainwater on the wall from pouring into the window frame.

[0031] 6. The gap between the galvanized steel sub-frame and the outer frame jamb module is filled with high-density hydrophobic rock wool, and then the external irregular gaps are filled with shotcrete to ensure the functions such as density, thermal insulation performance and airtightness at the internal joint.

[0075] 8. Construction of the inner frame lintel module 2:

[0076] (1) Install the galvanized steel sub-frame 21:

[0077] The galvanized steel sub-frame 21 adjusts the positioning and styling requirements of the inner frame lintel module 2 by adding a steel sub-frame; the steel sub-frame is connected to the outer structure of the outer frame lintel module 1 through anchor bolts.

[0078] (2) Sealing the inner side of the galvanized steel sub-frame 21 with a cement board 23:

[0079] On the side of the galvanized steel sub-frame 21 close to the window frame, a galvanized L-shaped corner code 24 is used to connect with the galvanized steel sub-frame 21, and a 15-mm high-density cement board 23 is externally sealed; the cement board 23 is flush with the inner side of the galvanized steel sub-frame 21.

[0080] (3) Installing the styling keel frame 22:

[0090] 9. Acceptance:

[0091] (1) The construction quality shall meet the requirements of the relevant provisions of the "Code for Acceptance of Construction Quality of Concrete Structures" GB50204-2015.

[0092] (2) For positioning, size and final effect requirements, it is recommended to refer to the "Quality Acceptance Standards for Building Decoration and Renovation Projects".

[0093] The main features of this embodiment are as follows:

[0094] 1. For complex window lintels, BIM technology is used for in-depth design, and corresponding architectural and structural models are established. Through the final effect of the building, the corresponding structural and architectural models are adjusted to determine the final high-precision BIM model.

[0095] 2. The BIM model is decomposed into the outer frame door module and the inner frame door module, which are used to deepen the design and guide the on-site construction briefing.

[0096] 3. By decomposing the complex window door into two stages of construction, the outer frame door module and the inner frame door module. The outer frame door module adopts the conventional structure and construction method, which is easy to construct, greatly improves the construction efficiency and reduces the impact on the critical construction period.

[0097] 4. The method of the inner frame door module is to add a galvanized steel sub-frame on the basis of the outer frame after the construction is completed, and the positioning accuracy requirements are met by adjusting the position of the sub-frame. The galvanized steel sub-frame is used to meet the requirements of complex theme modeling and anti-corrosion requirements due to the good machinability of steel components.

[0098] 5. The galvanized steel sub-frame is fixed to the outer frame door module through the surrounding positioning brackets and expansion anchors. It is easy to install. When there are local changes and adjustments on site, the positioning of the steel sub-frame can be adjusted by the length of the positioning brackets, and the construction operation is convenient.

[0099] 6. The gap between the sub-frame and the outer frame is filled with high-density hydrophobic rock wool (to meet the building insulation requirements), and the outer side is sprayed with shotcrete. Shotcrete has the advantages of good plasticity and density. It is effective and easy to construct to fill the irregular gaps between the doors and windows of the building and the structure; it not only meets the insulation requirements of the building wall, but also meets the density requirements of the structure.

[0100] 7. The waterproof layer at the joint extends from the wall waterproof layer to the window frame, and waterproof sealant is applied at the intersection. At the same time, in order to ensure the waterproof performance of the outer bell mouth joint, a cement-based waterproof layer is added, and the cement-based waterproof layer extends to the wall waterproof layer to form a closed loop, which enhances the waterproof performance at the joint.

[0101] 8. The outer trumpet shape adopts TCP closing, and C50 galvanized keel is selected as the theme packaging skeleton to meet the needs of the exterior theme shape. The interior is filled with hydrophobic rock wool to meet the wall insulation performance.

[0102] In view of the fact that it is difficult to achieve the artistic effect, time-consuming and laborious, and there are great potential quality hazards in the construction of complex-shaped decorative openings in theme parks in one go, the present invention adjusts the construction to two-stage construction to achieve the corresponding artistic effect.
