[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3As shown, this utility model embodiment provides a roof concrete joint-free waterproofing segmented structure, including a roof concrete layer 1 and multiple segmented strips 3. The roof concrete layer 1 has multiple partition joints, and the multiple segmented strips 3 are respectively embedded in the multiple partition joints. Each segmented strip 3 includes a segmented strip body 31 with an H-shaped cross-section and a first waterstop plate 32 that is vertically connected to both sides of the segmented strip body 31. Both first waterstop plates 32 extend into the roof concrete layer 1, and a first connector 41 connects the roof concrete layer 1 and the segmented strip body 31.

[0022] Furthermore, in this embodiment, the dividing strip body 31 forms a filling space 5 within the dividing joint, and a second connector 42 is provided within the filling space 5. It should be noted that both the first connector 41 and the second connector 42 are made of dry, hard mortar, and the top elevation of the second connector 42 during pouring is lower than the top of the filling space 5.

[0023] Furthermore, in this embodiment, a roof surface layer 2 is provided on the upper surface of the roof concrete layer 1, and the top of the dividing strip body 31 extends to the roof surface layer 2 and is flush with it. Preferably, a sealing element 6 is provided at the connection between the dividing strip body 31 and the roof surface layer 2, and two second waterstop plates 33 are vertically connected to both sides of the dividing strip body 31. Both second waterstop plates 33 extend into the roof surface layer 2, and the sealing element 6 is disposed between the second waterstop plates 33 and the dividing strip body 31. It should be noted that in this embodiment, the sealing element 6 is made of sealant to prevent leakage.

[0024] The construction steps for this utility model of a caulking-free, water-stopping, segmented roof concrete structure include:

[0025] 1) Construction preparation

[0026] Based on the roof area and design requirements, prepare sufficient quantities of waterproof dividing strips, hardened mortar, sealant, and other materials. The waterproof dividing strips should be made of high-strength, weather-resistant materials to ensure long-term performance; the hardened mortar should be pre-mixed according to a specific ratio; and the sealant should be a product with excellent waterproofing performance and strong adhesion.

[0027] 2) Installation and fixing of dividing strips

[0028] (1) Positioning and layout: According to the design requirements, position and layout the grid strips on the roof to determine the installation position of each grid strip, and mark it with ink lines or other marking methods.

[0029] (2) Install the dividing strips: Place the water-stop dividing strips on the roof according to the positioning lines. First, use a trowel to fill the cavity of the dividing strip with pre-mixed dry-hardened mortar, filling it to about 5-10mm from the top of the dividing strip; then, use a trowel to apply dry-hardened mortar to the outside of the dividing strip for fixation, with the height of the dry-hardened mortar on the outside being 3-5mm lower than the flange waterstop. During installation, gently tap the dividing strip with a rubber mallet to ensure it is in close contact with the base layer, while ensuring that the position and verticality of the dividing strip meet the requirements.

[0030] 3) Concrete pouring

[0031] Slowly pour the concrete onto the roof, starting from one end and gradually moving towards the other. During pouring, use a vibrator to compact the concrete, ensuring it is dense and preventing quality issues such as honeycombing or pitting. Take care to avoid direct contact between the vibrator and the dividing strips during vibration, as this could cause displacement or damage to the dividing strips.

[0032] After the concrete is poured, use a trowel to smooth the surface, making it flat and smooth. At the same time, pay close attention to the concrete around the dividing strips to ensure a tight bond between the dividing strips and the concrete.

[0033] 4) Roof surface layer laying and sealant injection

[0034] After the roof paving is completed, clean the joints and the areas where the paving bricks meet the roof paving bricks, removing debris and dust. Then, use a special caulking gun to evenly apply sealant to the joints and the areas where the sealant meets the roof paving bricks. When applying the sealant, ensure that the sealant fills all gaps and that the surface is smooth and even.

[0035] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
