Description

Technical Field

[0001] The present application relates to the field of construction engineering technology, and in particular to an adjustable metal roof assembly structure and an assembly method. Background Art

[0002] With the increasing number of steel structure buildings, the application of metal roofs has become more and more frequent. Metal roofs are widely used for their good structural rigidity, good waterproof performance, and easy installation.

[0003] In the prior art, purlins for installing metal roofs are usually reserved on the top of the steel structure building roof frame. Metal plates are installed on the purlins through mounting seats. The roof panels are usually assembled from multiple metal plates. However, the existing metal roof assembly structure has the following defects: 1. The metal plates and mounting brackets are all conventional parts, which makes their installation form single. However, the wind resistance required by buildings in different regions is different. The wind resistance required in areas prone to strong winds, such as the seaside and plains, is stronger, while the wind resistance required in areas not prone to strong winds, such as mountainous areas, is weaker. In view of the above situation, the single installation form of the metal plate cannot produce different sizes of wind resistance. Therefore, for a variety of different wind conditions, a variety of mounting brackets need to be designed to adapt to different wind resistance requirements, which not only increases production costs, but also increases the number of installation methods that construction personnel need to master, which is not conducive to the unified and standardized construction of buildings; 2. The existing metal plates are usually uneven in structure to increase their structural rigidity. The joints of adjacent metal plates are usually installed in an overlapping manner. However, as the use time increases, the overlapping joints are prone to warping or curling, which in turn causes the waterproofing and wind resistance to decrease, thereby causing hidden dangers in use.

[0019] S1. Fix the purlins on the roof trusses so that they are parallel to the ground. The purlins should be pre-opened with holes for inserting screws.

[0020] S2. Fix and connect the mounting plates to the parallel purlins. When installing the mounting plates, select first and second U-shaped panels of corresponding widths according to the local climate. Select the assembly method of each connector and the purlin based on the width of the selected first and second U-shaped panels: select the connector for installing the first U-shaped panel in a manner that makes the top of the mounting plate higher, and select the connector for installing the second U-shaped panel in a manner that makes the top of the mounting plate lower;

[0039] Additionally, the term "plurality" shall mean two or more.

[0040] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Example 1:

[0042] like Figures 1 to 6As shown, an adjustable metal roof assembly structure includes a roof truss 1 and a plurality of purlins 2, wherein the purlins 2 are arranged between the two ends of the roof truss 1 and are parallel to the ground, and at least two of the purlins 2 are parallel to each other, and further includes:

[0043] a plurality of first U-shaped panels 3 and a plurality of second U-shaped panels 4, wherein the first U-shaped panels 3 and the second U-shaped panels 4 are alternately laid between two parallel purlins 2, and the first U-shaped panels 3 are fixedly mounted on the top of the purlin 2 in an inverted manner, and the inner walls of the side panels of the first U-shaped panels 3 are abutted against the inner walls of the side panels of the second U-shaped panels 4;

[0044] A mounting plate 5 and a connecting piece, wherein the mounting plate 5 is fixedly connected to the purlin 2 via the connecting piece, the top of the mounting plate 5 is fixedly connected to the bottom of the transverse plate of the first U-shaped panel 3 or to the bottom of the transverse plate of the second U-shaped panel 4, and there are assembly methods between the connecting piece and the purlin 2 that make the top of the mounting plate 5 have two different heights. When the connecting piece and the purlin 2 adopt an assembly method that makes the top height of the mounting plate 5 higher, the mounting plate 5 is fixedly connected to the first U-shaped panel 3, and when another assembly method is adopted, the mounting plate 5 is fixedly connected to the second U-shaped panel 4.

[0045] Specifically, during installation, first install the purlin 2 parallel to the ground, and then install the first U-shaped panel 3 and the second U-shaped panel 4 on the purlin 2. Since the first U-shaped panel 3 is installed in an inverted shape, the height of its installation point is higher than the installation height of the second U-shaped panel 4. Therefore, by changing the assembly method of the connector and the purlin 2, the installation height of the mounting plate 5 is different to adapt to the installation of the first U-shaped panel 3 and the second U-shaped panel 4. It should be noted that in this embodiment, a plurality of installation points for installing connectors are pre-set on the purlin 2. According to the wind force in the area, the first U-shaped panel 3 and the second U-shaped panel 4 of different widths are selected. The number of connectors required for different widths is different. For example, for areas with less wind, the first U-shaped panel 3 and the second U-shaped panel 4 spanning four or five connector widths can be selected, while for areas with stronger wind, a metal panel spanning only one connector width can be selected.

[0046] It should be noted that in this embodiment, both the first U-shaped panel 3 and the second U-shaped panel 4 have thickened plates, on which bolts are fixed, and openings suitable for the bolts are opened on the mounting plate 5. This method avoids the situation where the bolts directly penetrate the panel and reduce its waterproof performance.

[0047] In this embodiment, the roof panels are designed as two U-shaped panels connected at intervals, and the connectors are designed in two different ways to be assembled with the purlin 2, one of which conforms to the normal installation of one panel and the other to the inverted installation of the other panel. This enables the assembly structure of the metal roof panel to meet the installation scenarios with various different wind force requirements. At the same time, for construction workers, only by mastering the two different connection methods of the connectors, they can achieve the assembly of the roof panels in different scenarios, thus reducing the learning cost and management cost of the construction workers, which is conducive to the unified standardization construction of the building.

[0048] The cross-section of the purlin 2 is in a "匚" shape, the connector is a 匚-shaped plate 6, the outer height of the 匚-shaped plate 6 is equal to the inner height of the purlin 2, and a plurality of corresponding through holes 7 are respectively and penetratingly provided on the top plate and the bottom plate of the purlin 2 and the 匚-shaped plate 6. A screw rod 8 adapted to the through hole 7 is fixedly provided at the bottom of the mounting plate 5.

[0049] Specifically, the 匚-shaped plate 6 can be optionally installed on the top of the purlin 2 or in the inner cavity of the purlin 2. The bottom of the mounting plate 5 has a screw rod 8 adapted to the through hole 7. When the 匚-shaped plate 6 is installed on the top of the purlin 2, the mounting plate 5 on the top of the 匚-shaped plate 6 is used to install the first U-shaped panel 3. The screw rod 8 of the mounting plate 5 penetrates through the entire 匚-shaped plate 6 and is fixed to the top of the inner wall of the purlin 2 by a nut at the bottom. At this time, the main function of the 匚-shaped plate 6 is to raise the mounting plate 5; when the 匚-shaped plate 6 is installed inside the purlin 2, the screw rod 8 penetrates through the entire purlin 2 and the 匚-shaped plate 6 and is fixedly connected by a nut. At this time, the main function of the 匚-shaped plate 6 is to enhance the connection stability at the connection of the mounting plate 5. It should be noted that here, the screw rod 8 needs to penetrate at least three through holes 7 on the purlin 2 and the 匚-shaped plate 6, and each screw rod 8 is fixed by at least two nuts at different through holes 7 to enhance the connection stability of the screw rod 8 and reduce the loosening of the screw rod 8 due to the increase in service time, thereby causing the panel to shake and reducing the waterproof performance.

[0050] Sealing rubber strips 9 are fixedly provided on the inner walls of the side plates of the first U-shaped panel 3 and the second U-shaped panel 4.

[0051] Specifically, the sealing rubber strip 9 makes the sealing performance of the contact part between the two better and improves the waterproof performance; it should be noted that the position of the sealing rubber strip 9 on the first U-shaped panel 3 here is preferably lower than the position of the sealing rubber strip 9 on the second U-shaped panel 4, so that there is also a limiting effect in the vertical direction between the two panels, avoiding the vertical deviation of the two panels with the increase in service time, thereby reducing the waterproof ability.

[0052] A locking assembly is also fixedly arranged between the two side panels of the first U-shaped panel 3; the locking assembly includes a plurality of plug-in boards 10, two plug-in rods 11, and a plurality of connecting rods 12. The plug-in boards 10 are symmetrically arranged in a linear array on the inner walls of the two side panels of the first U-shaped panel 3. The two plug-in rods 11 are respectively fixedly connected to all the plug-in boards 10 on both sides. The connecting rod 12 is fixedly arranged between the two plug-in rods 11, and the connecting rod 12 also has an abutting portion for abutting the second U-shaped panel 4 on both sides.

[0053] Specifically, the plug rod 11 is fixedly connected to the plug board 10, and the connecting rod 12 is fixedly connected to the plug rods 11 on both sides, so that the distance between the two side panels of the first U-shaped panel 3 can be limited by the length of the connecting rod 12. As the first U-shaped panel 3 is used for a longer time, its two side panels may tend to deflect outward or shrink inward, and the length of the connecting rod 12 remains unchanged, thereby offsetting this movement trend. At the same time, the abutting portion on the connecting rod 12 is used to abut the outer wall of the side panel of the second U-shaped panel 4, ensuring that the connection between the two panels is always in a tightly abutted state, thereby ensuring the waterproof effect of the connection between the two panels.

[0054] The plug board 10 is provided with a socket, and the plug rod 11 is inserted into the sockets on all the plug boards 10 on the same side. Both ends of the plug rod 11 have threads, and the plug rod 11 is fixedly connected to the plug board 10 by nuts that match the threads at both ends; the connecting rod 12 has two symmetrically arranged docking ports, which are sleeved on both ends of the plug rod 11 and fixed by nuts; there are two connecting rods 12, and the two connecting rods 12 are fixedly arranged at both ends of the plug rod 11 respectively.

[0055] Specifically, the insertion rod 11 is used here to connect with the sockets on multiple plug-in boards 10 at the same time, so that the limiting effect of the insertion rod 11 on the side panel is more uniform, thereby avoiding the uneven deformation of the first U-shaped panel 3 under single contact conditions. During installation, the two insertion rods 11 are inserted into the multiple plug-in boards 10 on both sides, so that the threaded parts at both ends are passed through, and then the two connecting rods are respectively plugged into the two ends of the two insertion rods 11, and finally the insertion rod 11, the plug-in board 10 and the connecting rod 12 are fixed by nuts.

[0056] The abutting portion includes an abutting rod 14 and a rubber cap 15 . The abutting rod 14 is fixedly disposed at the bottom of the connecting rod 12 , and the rubber cap 15 is sleeved on the end of the abutting rod 14 .

[0057] Specifically, during installation, the rubber cap 15 is put on the abutment rod 14 after the connecting rod 12 is installed and fixed. The rubber cap 15 should abut against the outer wall of the side plate of the second U-shaped panel 4, and the connection between the second U-shaped panel 4 and the first U-shaped panel 3 is pressed tightly.

[0058] In this embodiment, a connecting rod 12 is provided to connect the two side panels of the first U-shaped panel 3 to limit the distance therebetween, and the side panels of the second U-shaped panel 4 are pressed against it, so that curling or warping is not likely to occur at the connection between the two, thereby ensuring good waterproof performance.

[0059] On the other hand, the present application also provides an adjustable metal roof assembly method, which is applied to the above-mentioned adjustable metal roof assembly structure, comprising the following steps:

[0060] S1. Fix the purlin 2 on the roof truss 1 so that the purlin 2 is parallel to the ground. The purlin 2 is pre-opened with a through hole 7 for inserting the screw 8. Specifically, the spacing between the through holes 7 on the purlin 2 is fixed. The width of the first U-shaped panel 3 and the second U-shaped panel 4 can be set according to the spacing between the through holes 7. The width difference between panels of different models is one through hole 7 spacing.

[0061] S2. Fix the mounting plates 5 on the purlins 2 that are parallel to each other. When installing the mounting plates 5, select the first U-shaped panel 3 and the second U-shaped panel 4 of corresponding width according to the local climate. Select the assembly method of each connector and the purlin 2 according to the width of the selected first U-shaped panel 3 and the second U-shaped panel 4: the connector used to install the first U-shaped panel 3 is selected in a connection method that makes the top of the mounting plate 5 higher, and the connector used to install the second U-shaped panel 4 is selected in a connection method that makes the top of the mounting plate 5 lower. Specifically, first fix and install the mounting plates 5, and determine the assembly method of the connectors according to the pre-selected panel width. Pay attention to the spacing between the two panels, so the mounting plates 5 used to install the two panels must also be set at a corresponding spacing.

[0062] S3. Install all the second U-shaped panels 4 on the lower mounting plate 5 at the top. Be careful not to damage the integrity of the second U-shaped panels 4 during installation to avoid water leakage.

[0063] S4. Install all the first U-shaped panels 3 on the mounting plate 5 with the higher top. During installation, insert the two side walls of the first U-shaped panel 3 into the two adjacent second U-shaped panels 4 respectively. When inserting, slightly bend the side panels of the first U-shaped panel 3 to deform it so that it can be inserted into the second U-shaped panel 4. After releasing your hand, the side walls of the first U-shaped panel 3 and the side walls of the second U-shaped panel 4 will be against each other. During operation, since there are sealing strips 9 on the inner walls of the side panels of the first U-shaped panel 3 and the second U-shaped panel 4, the side panels must be bend outwards during installation so that the two can be docked and installed.

[0064] S5. Install a locking assembly between the two side panels of the first U-shaped panel 3. The locking assembly limits the distance between the two side panels of the first U-shaped panel 3 to prevent deformation and failure. It also abuts against the outer walls of the side panels of the second U-shaped panel 4 to prevent outward deformation. Specifically, the locking assembly pulls the side panels of the first U-shaped panel 3 inward and pushes the side panels of the second U-shaped panel 4 inward, ensuring a good connection between the two and reducing the possibility of curling or warping.

[0065] Example 2: This example differs from Example 1 in that the connecting rod 12 is a telescopic tension rod. Specifically, the length of the telescopic tension rod can be adjusted after installation, allowing the two side panels of the first U-shaped panel 3 to tend to tighten inward, thereby improving the compression effect between the first U-shaped panel 3 and the second U-shaped panel 4. Compared with Example 1, the connecting rod 12 of this application has a better locking effect, but the cost is higher.

[0066] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.

Select the assembly method of each connector and the purlin (2) according to the width of the selected first U-shaped panel (3) and the second U-shaped panel (4): the connector for installing the first U-shaped panel (3) is selected to make the top of the mounting plate (5) higher, and the connector for installing the second U-shaped panel (4) is selected to make the top of the mounting plate (5) lower; S3. Install all the second U-shaped panels (4) on the lower mounting plate (5) at the top. Be careful not to damage the integrity of the second U-shaped panels (4) during installation to avoid water leakage; S4. Install all the first U-shaped panels (3) on the top higher mounting plate (5). When installing, insert the two side walls of the first U-shaped panel (3) into the two adjacent second U-shaped panels (4). When inserting, slightly bend the side panels of the first U-shaped panel (3) to deform it so that it can be inserted into the second U-shaped panel (4). After releasing the hand, the side walls of the first U-shaped panel (3) and the side walls of the second U-shaped panel (4) are against each other. S5. Install a locking assembly between the two side plates of the first U-shaped panel (3), so that the locking assembly limits the distance between the two side plates of the first U-shaped panel (3) to prevent deformation and failure, and at the same time presses against the outer wall of the side plate of the second U-shaped panel (4) to prevent outward deformation.
