Description

Technical Field

[0001] The utility model relates to the technical field of building roof structures, in particular to a deformation joint structure used for roof waterproofing. Background Art

[0002] Buildings often deform under external influences such as climate and temperature fluctuations, leading to cracking and even damage. Expansion joints are structural joints designed to address these conditions. Building roofs are often exposed to wind and sun, and expansion joints protect the overall structural stability of the roof. Conventional roof expansion joints typically have raised edges on both sides, with waterproofing material filling the gaps. However, over time, the width and vertical displacement of the expansion joint can create gaps between the waterproofing material and the joint, allowing rainwater to easily flow into the joint and cause leakage.

[0006] Furthermore, a separation layer is provided between the profiled plate and the fireproof layer, and the upper and lower surfaces of the separation layer are respectively in contact with the fireproof layer and the profiled plate.

[0007] Furthermore, a second pressure strip is provided above the fireproof layer, and a plurality of fasteners are provided along the length direction of the second pressure strip, and the second pressure strip is fixedly connected to the flange through the fasteners.

[0008] Furthermore, a waterproof roll is provided above the second pressure strip, and the waterproof roll covers the upper side of the deformation joint body. Corresponding waterproof rolls are provided on both sides of the deformation joint body. First pressure strips are provided.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0022] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0023] like Figures 1 to 6 As shown, a deformation joint structure for roof waterproofing includes a deformation joint body 1, and the deformation joint body 1 includes a gap 11 and a roof 12. The roof 12 on both sides of the gap 11 is provided with a convex edge 121. A protective layer 2 is provided above the deformation joint body 1. The protective layer 2 component provides primary protection for the deformation joint to prevent external water from penetrating into the deformation joint. A top pressure component 3 is provided above the protective layer 2, and asphalt hemp 31 is filled between the top pressure component 3 and the protective layer 2. The asphalt hemp 31 can provide secondary waterproof protection for the deformation joint and improve the waterproof performance of the deformation joint. The outermost top pressure component 3 forms a stable protection for the entire waterproof deformation joint structure.

[0024] The protective layer 2 includes a corrugated plate 22 and a fireproof layer 23. The bottom surface of the corrugated plate 22 is bonded to the roof 12. The fireproof layer 23 is provided above the corrugated plate 22, and the fireproof layer 23 is bonded to the outer surface of the flange 121. The corrugated plate 22 has excellent mechanical properties of resistance to deformation, and provides stable protection for the roof 12 and the expansion joint. The fireproof layer 23 can prevent the fire from causing adverse effects on the entire roof 12, including the expansion joint. A partition layer 221 is provided between the corrugated plate 22 and the fireproof layer 23. The upper and lower surfaces of the partition layer 221 are bonded to the fireproof layer 23 and the corrugated plate 22 respectively. The main material of the partition layer 221 is PE film, which can reduce the oxidation effect of air on the surface of the corrugated plate 22, so that the corrugated plate 22 maintains stable mechanical properties. A second bead 21 is provided above the fireproof layer 23. Multiple fasteners 211 are provided along its length, securing the second bead 21 to the flange 121 via the fasteners 211. This second bead 21 ensures a better fit between the protective layer 2 and the flange 121, preventing water from seeping into the expansion joint through the gap between the protective layer 2 and the flange 121. A waterproof roll is provided above the second bead 21, covering the expansion joint body 1. Corresponding first bead 131 is provided on either side of the expansion joint body 1. The waterproof roll is securely attached to the protective layer 2 via the first bead 131.

[0025] The top pressure assembly 3 includes a plurality of top blocks 32, and the plurality of top blocks 32 can be detachably connected to form the entire top pressure assembly 3. The plurality of freely spliced top blocks 32 are convenient for transportation and assembly. One side of the top block 32 is provided with symmetrically distributed positioning blocks 321, and the other side is provided with positioning holes that match the positioning blocks 321. The plurality of top blocks 32 are connected as a whole through the cooperation of the positioning blocks 321 and the positioning holes. The various top blocks 32 can be quickly assembled through the positioning blocks 321 and the positioning holes. One side of the top block 32 is provided with a side edge 322, and the other side is provided with a step 323 that matches the side edge 322. Asphalt is coated between the side edge 322 and the step 323. The cooperation between the side edge 322 and the step 323 increases the contact area between different top blocks 32. By applying asphalt on the step 323, the sealing and waterproof performance between the top blocks 32 can be improved.

[0026] The working principle of this embodiment of the utility model is as follows: The waterproof membrane and protective layer 2 form a primary barrier to the expansion joint, preventing adverse effects from rain or fire. The asphalt hemp fiber 31 forms a secondary waterproof barrier to the expansion joint, enhancing its waterproof performance. The top pressure assembly 3 forms the outermost layer of physical protection, ensuring the stability of the overall waterproof expansion joint structure.
