Technical Field

[0001] The present invention relates to the technical field of thermal insulation board construction, and specifically to a construction process for a composite roof thermal insulation board. Background Art

[0002] The traditional roof thermal insulation construction process has multiple structural layers, multiple construction procedures, a relatively high cost, and it is difficult to guarantee the quality. Especially, its thermal insulation performance cannot meet the overall requirements of current energy conservation and consumption reduction. Moreover, it requires a long construction period and has low construction efficiency.

[0003] Therefore, it is necessary to design a composite roof thermal insulation integrated board and its construction process to make the roof have obvious heat insulation effect, fire resistance and shock absorption, simple construction and low cost. Summary of the Invention

Pave the thermal insulation integrated board: Spread the dry-mixed cement mortar on the roof, hammer and level it according to the set slope and flatness, take out the thermal insulation integrated board, apply neat cement mortar on the reverse side of the thermal insulation integrated board, and then pave, hammer and level it. When paving, leave a board joint with a width of 8 - 10 mm, and leave a separation joint with a width of 15 - 20 mm; S6. Treat the board joint and separation joint: Before filling the joint, remove the sundries in the board joint and separation joint, fill with the same-grade thermal insulation mortar, and carry out joint filling treatment with polymer waterproof sealant.

[0014] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] Embodiment: As Figure 1 - Figure 2 shown, a construction process for a composite roof thermal insulation board includes the following steps: S1. Preparation before construction: Carry out design optimization, deepen the plan for different roofs, layout according to the size of the composite roof thermal insulation integrated board, draw a layout plan for the board-laying roof in advance. The layout takes into account the details of equipment foundations, thermal insulation exhaust pipes, ventilation pipes, rainwater inlets, pipe wells, etc. The layout of the board-laying roof is reasonable, beautiful, without broken joints, and integrated with the prominent structures on the roof such as equipment foundations and pipe wells, symmetric, centered, and natural and harmonious.

[0016] S2. Clean the base layer and construct the isolation layer: Clean the base layer, wash it with water without damaging the waterproof layer, and construct the isolation layer after the base layer is cleaned.

[0017] S3. Leveling and setting out lines: Before paving, set out lines and level the surface, control the thickness of the paving mortar to be ≥20mm, and set out lines according to the specifications of the boards, board joints and dividing joints; The slope and leveling layer of the roof adopts LC5.0 lightweight aggregate concrete with a 3% slope, and the thinnest part is 20mm.

[0018] S4. Preparing mortar: When using ready-mixed mortar on site for paving, prepare the mortar according to the ratio of cement:sand = 1:2.5 - 3 (mass ratio); It is advisable to mix the mortar on the ground. If mixing mortar on the roof, protective measures must be taken and mortar shall not be directly mixed on the waterproof layer 5.

[0019] S5. Laying the thermal insulation and heat insulation integrated board: Adopt the dry-laying method, that is, use dry-mixed cement mortar (adding appropriate amount of water) to lay the thermal insulation and heat insulation integrated board 1. Spread the dry-mixed cement mortar on the roof, and use a rubber hammer to hammer and level it according to the set slope and flatness. Take out the thermal insulation and heat insulation integrated board, apply neat cement slurry on the reverse side of the thermal insulation and heat insulation integrated board 1, and then lay, hammer and level it. When laying, leave a 10mm-wide board joint 2 and a 20mm-wide dividing joint 3. Clean the dividing joint 3, and caulk it with waterproof grease; Do not strike with hard objects during laying. The surface should be flat, the board joints should be straight and of the same size to ensure smooth drainage. After laying the thermal insulation and heat insulation integrated board, water can be appropriately sprayed on the board surface to make the water seep into the board through the board joints, which is beneficial to the setting and hardening of the paving mortar; The thermal insulation and heat insulation integrated board 1 consists of a surface layer 11, an adhesive layer 12 and a thermal insulation layer 13 from top to bottom in sequence.

[0020] S6. Treatment of board joints and dividing joints: Before caulking, remove the sundries in the board joint 2 and the dividing joint 3, fill the same grade of thermal insulation mortar, and caulk with polymer waterproof sealant. Leave a 20mm-deep concave arc 4 on the surface after pressing and polishing; When caulking, first sweep the caulking material into the joint, pour water into the joint. The next day, when the water on the board surface is dry, pour water into the joint first, and then sweep the caulking material into the joint. When the capillary action makes the water mark appear on the surface of the caulking material, use a 12mm round steel with a bent head to draw and pull the board joint and the dividing joint to compact and polish them to ensure the waterproof effect; When caulking, clean up while caulking to avoid contaminating the brick surface.

[0021] In this embodiment, by adopting the composite thermal insulation integrated board and its construction technology, the roof decorative layer, adhesive layer and high-performance thermal insulation layer are integrated. Using industrialized composite technology, it is processed and compounded at one time in the factory. When applied to the roof, only cement mortar is needed to directly paste it on the roof waterproof layer, saving multiple on-site construction processes, so as to achieve the purpose of further energy conservation. The construction technology of the composite thermal insulation integrated board can form a wet operation at one time above the roof waterproof layer. Compared with the traditional roof construction technology, it greatly improves the construction efficiency and saves nearly 1 / 2 of the construction period; because at least one wet operation construction process is saved, compared with the traditional construction technology, it can save nearly 1 / 3 of the labor cost, and the cumulative savings of other costs is 6%, with obvious economic benefits. The composite thermal insulation integrated board is a "breathable thermal insulation layer", with rigid waterproofing on the surface layer, fast drainage, good air permeability, no water storage on the roof, and the waterproof and thermal insulation extend the service life.

[0022] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent solutions made by using the content of the specification of the present invention and directly or indirectly applied in other related technical fields are equally within the patent protection scope of the present invention.
