Description

Technical Field

[0001] The utility model relates to the technical field of building curtain walls, in particular to an upright locking edge metal roof structure of a TPO waterproof composite board. Background Technique

[0002] A metal roof refers to a roof form that uses metal plates as roof covering materials and combines the structural layer and the waterproof layer into one. There are many types of metal plates, including galvanized plates, aluminized zinc plates, aluminum alloy plates, aluminum magnesium alloy plates, titanium alloy plates, copper plates, stainless steel plates, etc. The surface of the plates can be treated with baking paint, mainly including four types of baking paint treatments: PE / PE, SMP / PE, HDP\PE, and PVDF\PE. The baking paint can extend the service life of the plates, which are 5 - 8 years, 10 - 15 years, 15 - 20 years, and more than 20 - 25 years respectively.

[0003] In the current metal roof structure, the roof will cause repeated fatigue damage to the coil under the action of long - term temperature effects. The expansion and contraction caused by the temperature effect will cause stress concentration at the detailed node positions. If there are too many coil joints and the welding is not firm at this part, it is easy to cause tearing and lose the waterproof effect. In addition, at the edge - closing parts such as the gutter, it is easy to form leakage under the influence of wind force and indoor - outdoor pressure difference during the rainy and windy seasons, and the roof lacks a support structure, so that the roof is prone to collapse and damage. In view of the above problems, the inventor proposes an upright locking edge metal roof structure of a TPO waterproof composite board to solve the above problems. Content of the Utility Model

[0004] In order to solve the problems that the overall waterproof performance of the existing metal roof is poor and the roof lacks a support structure, resulting in the roof being prone to collapse and damage; the purpose of the utility model is to provide an upright locking edge metal roof structure of a TPO waterproof composite board.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment: As Figure 1-7 shown, the present utility model provides an upright-seamed metal roof structure of a TPO waterproof composite board, including a waterproof composite profiled steel sheet 1, a thermal insulation layer 2 is fixedly arranged at the center of the top of the waterproof composite profiled steel sheet 1, a waterproof composite roof panel 4 is fixedly arranged on the top of the thermal insulation layer 2 through a plurality of aluminum alloy fixed supports 3, a support mechanism 5 is arranged at the center of the bottom of the waterproof composite profiled steel sheet 1, and steel structures 6 are symmetrically and fixedly arranged on both sides of the bottom of the waterproof composite profiled steel sheet 1.

[0022] The support mechanism 5 includes two support plates 501 symmetrically and fixedly arranged at the center of the bottom of the waterproof composite profiled steel sheet 1, and a connecting rod 502 is hinged on one side of the support plate 501, and one ends of the two opposite connecting rods 502 are hinged and matched.

[0023] By adopting the above technical solution, the rotation of the connecting rod 502 can change the distance between the two support plates 501.

[0024] Chutes are symmetrically arranged at both ends of the top of the support plate 501. Adjusting rods 503 are slidably arranged in the chutes. One end of each adjusting rod 503 is fixedly provided with a support block 504. A plurality of first through holes are symmetrically arranged at both ends of one side of the support plate 501. The first through holes communicate with the chutes. A plurality of second through holes are arranged on one side of each adjusting rod 503.

[0025] By adopting the above technical solution, the movement of the adjusting rod 503 can drive the support block 504 to move, further adjusting the support area of the support mechanism 5.

[0026] An L-shaped fixing rod 505 is fixedly arranged on the outer ring of the bottom of the support plate 501. A through hole is arranged on one side of the L-shaped fixing rod 505. A guide rod 506 is slidably arranged in the through hole. One end of the guide rod 506 is fixedly provided with a connecting block 507. A limiting rod 508 is fixedly arranged on one side of the connecting block 507. The limiting rod 508 is in clamping fit with one of the first through holes and the second through holes. A spring 509 is fixedly arranged between the L-shaped fixing rod 505 and the connecting block 507. The spring 509 is sleeved on the guide rod 506.

[0027] By adopting the above technical solution, the movement of the limiting rod 508 can limit the adjusting rod 503 and the support block 504.

[0028] Support rods 510 are fixedly arranged at both ends of the bottom of the support plate 501 and at the bottom of the support block 504. The bottoms of the support rods 510 are fixedly provided with U-shaped support seats 512 through fixing bolts 511.

[0029] By adopting the above technical solution, the movement of the support rods 510 can adjust the heights of the support plate 501 and the support block 504.

[0030] An installation block 513 is fixedly arranged at the bottom of the U-shaped support seat 512. A plurality of fastening bolts 514 are threadedly arranged at the top of the installation block 513.

[0031] By adopting the above technical solution, the tightening of the fastening bolts 514 can install and fix the installation block 513.

[0032] The heat insulation layer 2 is made of heat insulation cotton.

[0033] By adopting the above technical solution, the heat conductivity of the heat insulation cotton is low, which can prevent the external hot air from entering the room in summer and also avoid the loss of indoor heat in winter.

[0034] A waterproof and breathable membrane 7 is fixedly arranged between the waterproof composite roof panel 4 and the heat insulation layer 2.

[0035] By adopting the above technical solution, the distance between gas molecules is relatively large, and they can pass through the ventilation holes of the waterproof and breathable membrane 7 during the diffusion movement. However, the distance between liquid molecules is smaller than the distance between the ventilation holes, and under the action of surface tension, the liquid molecules cannot pass through the waterproof and breathable membrane 7, thus playing a waterproof role.

[0036] Working principle: When installing this metal roof structure, the installation and fixation are carried out according to the following steps:

[0037] (1) Installation process of the waterproof composite profiled steel sheet 1: a. The length of the waterproof composite profiled steel sheet 1 is actually measured by the engineer at the construction site for the length data of each span of the roof, and the actually measured values of each part are summarized into the processing list of the waterproof composite profiled steel sheet 1 and handed over to the factory for processing; b. The waterproof composite profiled steel sheet 1 is transported to the construction site and then moved to the roof operation area by a combination of manual and mechanical means and stacked in the material area, paying attention to doing a good job in rain and waterproof measures; c. Before installation, it is necessary to first pop the installation control line of the waterproof composite profiled steel sheet 1 according to the layout design drawing of the waterproof composite profiled steel sheet 1 on the roof to control the installation position, lay it above the roof steel structure 6, and then fix it on the steel structure 6 with self-tapping screws. Regarding the spacing between the fixing screws of the waterproof composite profiled steel sheet 1 on the roof; d. The laying spacing of the waterproof composite profiled steel sheet 1 must meet the design requirements, and its connection and fixation with the steel structure 6 should be firmly anchored. When fixing the laid waterproof composite profiled steel sheet 1 with self-tapping screws, the self-tapping screws should be on a horizontal line and inspected with a straightedge. Any error exceeding 8 mm should be retrimmed and fixed so that the exposed screws are straight when straight and arc-shaped when curved, with a smooth transition; e. When laying the waterproof composite profiled steel sheet 1, the longitudinal lap length between each sheet of the waterproof composite profiled steel sheet 1 shall not be less than 80 mm, and the transverse lap is one wave crest with each other. If there is a large gap when the plates contact each other, it is necessary to fasten them appropriately with aluminum rivets; f. When installing the waterproof composite profiled steel sheet 1, attention should also be paid to the lap of the rib part of the bottom plate, which should be aligned to ensure the mutual penetration between the plates; g. After the installation of the waterproof composite profiled steel sheet 1 is completed, its laying direction needs to meet the layout design, the connection at the edge of the plate is firm, the opening at the intersection with the purlin support is accurate, and there are no residues and dirt on the plate surface; h. The joints of the installed waterproof composite profiled steel sheet 1 are tight, the joints are straight, the anchoring is reliable, the longitudinal and transverse lap joints are straight lines, and the plate surface is flat and clean;

[0038] (2) Installation of the aluminum alloy fixed support 3: After drilling holes in the waterproof composite profiled steel sheet 1, use an electric screwdriver to drive stainless steel screws. The stainless steel screws should be tightened moderately without skewing. When installing the aluminum alloy fixed support 3, the heat insulation pad below it must be installed simultaneously. After drilling each screw hole, immediately drive a screw. Each aluminum alloy support should be fixed with no less than 3 screws (4 screws are normally used for fixing), but 4 screws must be used for fixing the aluminum alloy fixed support 3 at the eaves to ensure that the stability of the overall roof meets the requirements and prevent the roof from being blown open by strong winds;

[0039] (3) Installation process of the insulation layer 2: a. Check the specifications, quantity, thickness, packaging, and moisture condition. For unqualified ones, especially the insulation cotton that has been rained on, it must be returned or processed. Thickness measurement: After the insulation cotton is rolled and packaged, it is fully compressed. The thickness can be measured after unrolling and patting or after turning the roll and allowing the insulation cotton to fully rebound for more than 4 hours; b. The storage site should be in a warehouse, which should be kept dry with windproof, rainproof, and fireproof facilities. When temporarily stacked on site, the surface should be covered with fireproof cloth and fire extinguishers should be provided; c. Lift the materials to the roof by installing fixed pulleys on the roof, and use up the insulation materials transported to the roof immediately to avoid large-scale stacking; d. The installation of the waterproof composite roof panel 4 is carried out simultaneously. When installing the insulation cotton first and then laying the waterproof composite roof panel 4, the distance between the insulation cotton and the waterproof composite roof panel 4 should not be too long. Ensure that the insulation cotton laid at that time is covered by the installation of the waterproof composite roof panel 4. When the insulation cotton passes through the aluminum alloy fixed support 3, it must be cut with a blade on the insulation cotton and then passed through the aluminum alloy fixed support 3. It is strictly prohibited to forcibly damage the insulation layer 2; e. The insulation cotton should be closely attached to the surface of the base layer. The flat joints should be tightly squeezed and the upper and lower joints should be staggered from each other. When the roof slope is large, it is advisable to use special metal or plastic fasteners to fix the fiber insulation material to the base layer. After the fiber material is filled, no one should step on it;

[0040] (4) Installation of the waterproof and breathable membrane 7: The waterproof and breathable membrane 7 is constructed in sequence from bottom to top along the roof. Each section of the waterproof and breathable membrane 7 is paved from top to bottom, and the sections are overlapped vertically in the downstream direction. If the construction flow arrangement cannot meet the sectional construction sequence from bottom to top, it should be ensured that the waterproof and breathable membrane 7 is overlapped vertically in the downstream direction;

[0041] (5) Installation of the waterproof composite roof panel 4: When the waterproof composite roof panel 4 is placed in position on the aluminum alloy fixed support 3, it is necessary to ensure that it extends 10 cm into the ridge, with a 6-cm flanging, and extends into the gutter by no less than 12 cm; during installation, the small side of the waterproof composite roof panel 4 should completely hold the plum blossom head of the aluminum alloy fixed support 3, and then be completely buckled by the large side of the adjacent roof panel. Temporarily lock the waterproof composite roof panel 4 at the position of the aluminum alloy fixed support 3 together with a manual crimper. There are expansion fixing points for the waterproof composite roof panel 4 at the ridge. Use rivets to penetrate through the small side of the waterproof composite roof panel 4 and the plum blossom head of the aluminum alloy fixed support 3, and lay the waterproof composite roof panel 4 forward according to this plan.

[0042] When the support mechanism 5 needs to be installed, rotate the connecting rod 502 to drive the movement of the two support plates 501, changing the support area of the entire support mechanism 5. Hold the guide rod 506 and pull the guide rod 506, thereby driving the movement of the connecting block 507 and the limiting rod 508, causing the limiting rod 508 to disengage from the first through-hole and the second through-hole. Then adjust the positions of the adjusting rod 503 and the support block 504 to further change the support area of the support mechanism 5. Then install the support plates 501 and the support blocks 504 at the bottom of the waterproof composite profiled steel sheet 1, thus playing a good supporting role for the entire metal roof.
