Description

Technical Field

[0001] The utility model relates to the technical field of deformation joint nodes, in particular to a roof deformation joint node. Background Art

[0002] Building deformation joints, also known as expansion joints, refer to a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate and temperature changes. To prevent water leakage from expansion joints, a concrete counter-ridge with a height of ≥250mm is usually poured on the roof, and galvanized iron sheets and waterproof membranes are used to fix the top of the counter-ridge; although this method is convenient and quick to construct, it is prone to leakage risks due to loose cover fixation or aging of the membrane, resulting in economic losses in later repairs. Therefore, a new method is proposed to solve this quality risk.

[0003] Traditionally, concrete counter-bumps are poured on both sides of the roof expansion joint, and the roof waterproofing membrane extends to the side wall of the counter-bump. A waterproof additional layer is set on the top to fix it to the top of the counter-bump, and the top is compacted with galvanized iron sheets. This practice will cause the waterproofing membrane to age over time and be exposed to wind and sun, and the galvanized iron sheets will not be firmly fixed, resulting in leakage risks. Utility Model Content

[0004] The purpose of the present application is to solve the problem of leakage of existing roof deformation joint nodes due to wind and sun exposure, and the present application provides a roof deformation joint node.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0006] A roof deformation joint node comprises a floor slab, wherein an anti-ridge is fixedly connected to the floor slab, deformation joints are arranged between the floor slabs, a zinc iron sheet is fixedly connected to the anti-ridge and the floor slab, an insulation layer is arranged on the zinc iron sheet, a waterproof layer is arranged on the insulation layer, a zinc iron block is fixedly connected to the zinc iron sheet, a plastic rod is fixedly connected to the zinc iron block, a mounting structure is arranged between the anti-ridge and the deformation joint, and a leak-proof structure is arranged on the floor slab.

[0007] By adopting the above technical scheme, when the roof deformation joint node is used to install the deformation joint on the roof, first use cement to make anti-ridges on both sides of the deformation joint, then install the zinc iron sheet between the floor slab and the anti-ridge, then place the plastic plate on the zinc iron block, and then install the insulation layer and the waterproof layer on the zinc iron sheet through the installation structure, so that they can be installed together more stably, thereby improving the durability of the device, and then fill the waterproof board, the anti-ridge and the deformation joint through the leak-proof structure, thereby reducing the direct wind and sun exposure of the three surfaces, and further improving the leak-proof effect of the device.

[0008] Furthermore, the leakage-proof structure includes a foam board fixedly connected in the deformation joint, a sealing paste is fixedly connected to the upper end of the foam board, the zinc-iron block is fixedly connected to the sealing paste, and a sealing assembly is arranged on the floor slab.

[0009] By adopting the above technical solution, the foam board can better fill the middle of the deformation joint when the deformation joint shrinks and expands, thereby reducing the problem of water ingress into the deformation joint and improving the anti-leakage effect of the device.

[0010] Furthermore, the sealing component includes a pressure top fixedly connected to the counter-ridge, a cement mortar layer is fixedly connected to the waterproof layer, and a cement mortar layer is arranged between the pressure top and the counter-ridge.

[0011] By adopting the above technical solution, the cement mortar layer is used to avoid direct contact between the surface of the device and the outside, thereby improving the anti-leakage effect of the device and extending the life of the internal structure of the device.

[0012] Furthermore, the installation structure includes storage plates respectively fixedly connected to the two inner walls of the deformation joint, the storage plates are fixedly connected to limit pins, the foam plates are provided with limit grooves, the limit grooves are adapted to the limit pins, and a limit component is arranged between the floor slab and the waterproof board.

[0013] By adopting the above technical solution, the storage plate is placed in the deformation joint, and the foam plate is inserted from the deformation joint so that the limit groove at the lower end thereof is matched with the limit pin on the storage plate. Thus, after long-term use of the device, when the foam plate is damaged, the debris generated by it is collected so that it cannot enter deeper into the deformation joint, which facilitates the replacement and cleaning effect of the device when repairing the deformation joint.

[0014] Furthermore, a sliding bar and a sliding frame are fixedly connected to the two storage plates respectively, and the sliding bar is slidably connected to the sliding frame.

[0015] By adopting the above technical solution, when the storage plates are driven by the sliding bar and the sliding frame to contract and expand at the deformation joint, the storage plates on both sides move, thereby better filling the deformation joint.

[0016] Furthermore, the limiting assembly includes a limiting block fixedly connected to the zinc iron sheet, and a mounting groove is provided on the thermal insulation layer, and the limiting block is adapted to the mounting groove.

[0017] By adopting the above technical solution, the installation groove and the limit block are adapted to each other, so that the limit between the zinc iron sheet and the insulation layer is more stable and the movement between the two is reduced.

[0018] Furthermore, a mounting plate is placed on the waterproof layer, a mounting bar is fixedly connected between the mounting plate and the waterproof layer, a mounting bolt is slidably connected to the mounting plate, and the mounting bolt passes through the waterproof layer, the thermal insulation layer and is fixedly connected to the zinc iron sheet.

[0019] By adopting the above technical solution, the mounting bolt is hammered into the mounting plate, so that it passes through the mounting plate, the waterproof layer and the thermal insulation layer and finally passes through the zinc iron sheet, limiting the four together more tightly, thereby reducing the gap between the four and improving the anti-corrosion effect of the device.

[0020] Furthermore, a cement mortar board is fixedly connected to the pressure top, and the cement mortar board is provided with a 6% slope.

[0021] By adopting the above technical solution, the accumulation of water on the deformation joint is reduced and the permeability resistance of the deformation joint is improved.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. In the present application, when the device protects the expansion joint, a pressure top is added to the top of the expansion joint, and the gap between the pressure top and the deformation is sealed tightly with mortar. This method can reduce the erosion of the waterproof layer at the expansion joint by rainwater, reduce the risk of leakage caused by deformation and damage of the insulation board and waterproof board or loose installation of the zinc iron sheet, and improve the service life of the device.

[0024] 2. In the present application, a storage plate is placed in the deformation joint, fixed on the two walls of the deformation joint, and a sliding bar is placed in a sliding frame, and then a foam plate is inserted into the deformation joint. As a result, after a long period of use of the device, when the foam plate is damaged, the storage plate, the sliding frame and the sliding bar will collect the debris generated by the damage, so that the damage cannot enter deeper into the deformation joint, thereby facilitating the replacement and cleaning effect of the device when repairing the deformation joint.

[0035] When the roof deformation joint node is used to install the deformation joint on the roof, first use cement to make the anti-ridge 19 on both sides of the deformation joint, and then install the zinc iron sheet 3 between the floor 1 and the anti-ridge 19, so that the zinc iron block 9 covers the deformation joint, and then place the plastic plate on the zinc iron block 9, and then install the insulation layer 7 and the waterproof layer 6 on the zinc iron sheet 3 through the installation structure, so that they can be installed together more stably, thereby reducing the separation of voids caused by gap extrusion between the layers of the device, thereby improving the durability of the device, and then fill the waterproof board, the anti-ridge 19 and the deformation joint through the leak-proof structure, thereby reducing the direct wind and sun exposure of the three surfaces, thereby enhancing the service life of the device and further improving the leak-proof effect of the device.

[0037] When installing the device, the foam board 2 is inserted into the deformation joint, and then the sealing paste 10 is filled on the upper end of the foam board 2 to seal the upper end of the foam board 2 and the deformation joint. When the deformation joint is contracted and expanded, the foam board 2 can better fill the middle of the deformation joint, thereby reducing the problem of water ingress into the deformation joint. Then, the top pressure 4 is fixed on the anti-ridge 19 on one side, and finally the cement mortar layer 5 is covered between the top pressure 4 and the anti-ridge 19 to block the deformation joint of the sealing column. At the same time, the cement mortar layer 5 is covered on the waterproof layer 6 to connect the cement mortar layers 5 to each other, thereby avoiding direct erosion of the waterproof board and the structure in the deformation joint by wind and sun, thereby improving the service life of the device, making the device more durable and more difficult to be penetrated by rainwater.

[0040] Reference Figure 1A cement mortar board 20 is fixedly connected to the top pressure 4, and the cement mortar board 20 is provided with a 6% slope.

[0041] By setting a six percent slope on the cement mortar board 20, it is possible to effectively prevent water accumulation on the top of the deformation joint from causing damage to the device and the risk of leakage, thereby reducing the subsequent maintenance costs.

[0042] Working principle: When using the roof deformation joint node to install the deformation joint on the roof, first use cement to make the anti-ridge 19 on both sides of the deformation joint, and then install the zinc iron sheet 3 between the floor 1 and the anti-ridge 19, so that the zinc iron block 9 covers the deformation joint, and then place the plastic plate on the zinc iron block 9.

[0043] Now put the storage plate 11 into the deformation gap, fix it on the two walls of the deformation gap, and place the sliding bar 13 in the sliding frame 14, then insert the foam board 2 from the deformation gap, so that the limiting groove at its lower end is adapted to the limiting pin 12 on the storage plate 11, so that after long-term use, when the foam board 2 is damaged, the debris generated by it can be collected.

[0044] After the zinc iron sheet 3 is installed, the insulation layer 7 is placed on the zinc iron sheet 3 so that the installation groove at the lower end thereof matches the limit block 15, and then the waterproof layer 6 is placed on the insulation layer 7, and the installation plate 16 is placed on the insulation layer 7, and then the installation strip 17 is passed through the installation plate 16 and embedded into the waterproof layer 6, and finally the installation bolt 18 is hammered into the installation plate 16 so that it passes through the installation plate 16, the waterproof layer 6 and the insulation layer 7 and finally passes through the zinc iron sheet 3, and the four are more tightly limited together.

[0045] When installing the device, the foam board 2 is inserted into the deformation joint, and then the sealing paste 10 is filled on the upper end of the foam board 2 to seal the upper end of the foam board 2 and the deformation joint.
