Description

Technical Field

[0001] This invention belongs to the field of pitched roof tile construction technology, specifically a modular positioning and installation structure for auxiliary construction of pitched roof tiles. Background Technology

[0002] In the process of new urbanization, ecological garden city construction, and old city renovation in my country, it is often necessary to transform flat roofs into pitched roofs. Currently, the construction methods for pitched roof tiles are usually dry-laying and wet-laying methods. However, to ensure the stability of the tile installation, the wet-laying method is mostly used. The wet-laying method involves laying a layer of cement mortar on the concrete pitched roof surface and then bonding the tiles one by one. Before the tiles are installed, a row of wedge-shaped blocks is usually built at the front end of the eaves of the pitched roof to adjust the drainage slope of the tiles.

[0003] The existing wedge blocks are mostly installed manually, one by one, and then fixed to the pitched roof. This is not only inefficient, but also prone to human error, which can cause gaps between adjacent tiles and reduce their load-bearing capacity. Summary of the Invention

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0049] like Figures 1 to 5 As shown, this invention provides a modular positioning and installation structure for buildings, including an adjustment component and several installation components mounted on the adjustment component. The adjustment component is used to synchronously increase or decrease the spacing between the several installation components to change the installation spacing between two adjacent wedge blocks 35 on a pitched roof. The installation components include a connecting plate 1, a primary positioning plate 2, a backing plate 4, a secondary positioning plate 6, and mounting brackets 5 mounted on at least both ends of the connecting plate 1 of the adjustment component. The mounting brackets 5 are fixedly installed on the building wall to provide fixed support for the entire modular positioning and installation structure. The primary positioning plate 2 is welded to the bottom of the connecting plate 1 and forms an installation part 3 on one side of its adjacent end. The cross-sectional shape of the installation part 3 is a right-angled triangle, an acute-angled triangle, or an obtuse-angled triangle, specifically configured according to the structure of the selected wedge block 35. In this embodiment, refer to... Figure 1 and Figure 2 The mounting part 3 shown is a right-angled triangle. The mounting part 3 is used to horizontally position the wedge block 35. The liner 4 is located directly above the mounting part 3. One end of the liner 4 is welded to the top of the connecting plate 1. A fixing component is installed on the liner 4 to clamp the wedge block 35 onto the mounting part 3. The secondary positioning plate 6 is located on one side of the mounting part 3, and the adjacent ends of the secondary positioning plate 6 are welded to the adjacent sides of the connecting plate 1 and the primary positioning plate 2, respectively. It is used to position the wedge block 35 along the extension and retraction direction of the adjusting component. At the same time, the secondary positioning plates 6 on several connecting plates 1 are all located on the same side of the mounting part 3. This ensures that the installation distance on the side closer to the secondary positioning plate 6 is the same when installing wedge blocks 35 of different widths. It also acts as a tension rib to enhance the structural strength of the primary positioning plate 2.

[0050] In the above process, when positioning and installing the wedge block 35, the corresponding number of installation components are assembled by adjusting the components according to the number of wedge blocks 35 to be installed on the pitched roof, so that each installation component can be installed with one wedge block 35. Then, the wedge blocks 35 are inserted into the installation part 3 in sequence and positioned by the primary positioning plate 2 and the secondary positioning plate 6. Then, the wedge blocks 35 are clamped on the installation part 3 by the fixing components for fixation. Then, the entire modular positioning and installation structure and the assembled wedge blocks 35 are hoisted to the installation position on the pitched roof by a crane. After adjusting the installation position, the installation frame 5 is fixed to the building wall to avoid misalignment of the wedge blocks 35 during the pre-fixation construction on the pitched roof using fixing nails or concrete, thus improving the installation accuracy. After the wedge blocks 35 are fixed and formed on the pitched roof, the fixing components are operated. The component loosens the wedge block 35 and removes the mounting bracket 5, thereby removing the entire modular positioning and installation structure from the pitched roof to complete the overall positioning and installation of the wedge block 35. Compared with the previous construction method of manually placing the wedge blocks 35 one by one and then fixing them to the pitched roof, this method not only improves installation efficiency but also avoids installation errors caused by human factors (such as uneven placement of multiple wedge blocks 35 leading to inconsistent support heights provided by the wedge blocks 35 on the same horizontal line, resulting in gaps between adjacent tiles during installation), thus improving the load-bearing capacity of the tiles. At the same time, the adjusting component ensures that the installation spacing between adjacent wedge blocks 35 is consistent, thereby evenly distributing multiple wedge blocks 35 on the pitched roof, which helps to evenly distribute the load applied to the tile surface and further improve the load-bearing capacity of the tiles.

[0051] Furthermore, the fixing assembly includes a clamping block 7 and a stud 8. The clamping block 7 is disposed at the bottom of the liner plate 4. One end of the stud 8 is hinged to the top of the clamping block 7, and the other end of the stud 8 passes through the bottom of the liner plate 4 and extends to the top of the liner plate 4 to be fixedly mounted with a knob 9. The stud 8 is threadedly connected to the liner plate 4, and the central axis of the stud 8 coincides with the perpendicular bisector of the mounting part 3. This allows the stud 8 to be driven to move the clamping block 7 downward to clamp the wedge block 35 onto the mounting part 3 when the knob 9 is rotated; or the stud 8 to move the clamping block 7 upward to release the wedge block 35.

[0052] Furthermore, the adjustment assembly includes at least one set of connecting frames 10 and limiting rods 11. Each set of connecting frames 10 is rotatably mounted on two adjacent connecting plates 1, and the adjacent ends of the two adjacent connecting frames 10 are connected. This allows multiple connecting frames 10 to be combined into a hinge frame, so that when the hinge frame is open, the distance between the two adjacent connecting plates 1 is increased, and when the hinge frame is closed, the distance between the two adjacent connecting plates 1 is decreased, thereby achieving the function of synchronous adjustment of the distance between multiple connecting plates 1. Simultaneously, this adjustment assembly can be temporarily assembled on the construction site, which has advantages over traditional hinge frames. Excellent flexibility of use; the connecting frame 10 and the mounting part 3 are located on opposite sides of the connecting plate 1, respectively, to avoid interference from the sloping roof when installing the wedge blocks 35; one end of the limiting rod 11 passes through several connecting plates 1 in sequence, and is used to guide and position the connecting plates 1 during adjustment, so that they move on the same horizontal straight line; the other end of the limiting rod 11 is welded with a fixing platform 12, which is fixedly installed on the connecting plate 1, to prevent the limiting rod 11 from falling off during the hoisting process, which would cause the bottom surfaces of multiple wedge blocks 35 to be unable to be on the same horizontal plane. Among them, in order to facilitate the installation of the limiting rod 11, the top of the connecting plate 1 is set as a column shape, and a through hole for installing the limiting rod 11 is opened on the center line of the columnar surface of the connecting plate 1.

[0053] Specifically, the connecting frame 10 includes a first crank 13, a second crank 14, a third crank 15, and a fourth crank 16. The first crank 13, second crank 14, third crank 15, and fourth crank 16 are sequentially overlapped to form a rectangular frame, with the ends of adjacent cranks overlapping. The adjacent ends of the first crank 13 and second crank 14 are rotatably connected to the adjacent ends of the third crank 15 and fourth crank 16 via pins 17. Connecting members 19 are installed on the adjacent ends of the first crank 13 and fourth crank 16 and the adjacent ends of the second crank 14 and third crank 15, respectively. The connecting members 19 are rotatably mounted on the connecting plate 1 via pins 18. One end of the pin 18 is provided with a limiting portion, the structure of which can be referred to... Figure 3 The design shown is a hexagonal structure, which facilitates the tightening of the pin 18 with a wrench during installation, saving manpower; the other end of the pin 18 passes through the center line of two adjacent connectors 19 in sequence and is threaded onto the center of the connecting plate 1; and, the first crank 13 of one of the two adjacent connecting frames 10 and the third crank 15 of the other connecting frame 10 are installed on the same connector 19, and the fourth crank 16 of one of the two adjacent connecting frames 10 and the second crank 14 of the other connecting frame 10 are installed on the same connector 19.

[0054] Furthermore, the connector 19 includes a rotating ring 20 and an arc-shaped plate 23. Two bosses 21 are symmetrically arranged on the outer periphery of the rotating ring 20, and two fan-shaped mounting grooves 24 are formed between the two bosses 21 and the rotating ring 20. Threaded holes 22 are opened on the bosses 21, and the threaded holes 22 are perpendicular to the center line of the rotating ring 20. The concave surface of the arc-shaped plate 23 is installed on one of the fan-shaped mounting grooves 24. Rotating bolts are respectively provided at both ends of the opening of the arc-shaped plate 23 and on the side close to the bosses 21. The rotating bolts are threaded in the threaded holes 22. The convex surface of the arc-shaped plate 23 is installed on the first crank 13, the second crank 14, the third crank 15, or the fourth crank 16. In the above, the rotating bolt includes an external threaded sleeve 26, a fixing rod 27, and a limiting block 28. The external threaded sleeve 26 is threadedly installed in the threaded hole 22, and one end of the external threaded sleeve 26 extends to the outside of the threaded hole 22 and is fixedly installed with a rotating part 25. One end of the fixing rod 27 is fixedly installed on the arc plate 23, and the other end of the fixing rod 27 passes through the rotating part 25 and extends into the external threaded sleeve 26. The diameter of the fixing rod 27 is smaller than the inner diameter of the external threaded sleeve 26, and the center line of the fixing rod 27 coincides with that of the external threaded sleeve 26. The outer periphery of the limiting block 28 is slidably installed on the inner wall of the external threaded sleeve 26, and one end of the limiting block 28 is fixedly installed on the fixing rod 27. The linear motion stroke of the rotating part 25 on the fixing rod 27 is greater than the length of the external threaded sleeve 26, which is used to ensure that the external threaded sleeve 26 is completely installed in the threaded hole 22.

[0055] In the above embodiment, when assembling the connector 19 and each crank, first align and insert the two external threaded sleeves 26 on the arc plate 23 into the threaded hole 22, then rotate the rotating part 25 to screw the external threaded sleeves 26 into the threaded hole 22 until the rotating part 25 presses against the boss 21, thereby fixing the arc plate 23 in the fan-shaped mounting groove 24, completing the assembly of one crank with the connector 19. Similarly, other cranks are assembled in sequence according to the usage requirements of the connecting frame 10.

[0056] It should be noted that the cranks include the first crank 13, the second crank 14, the third crank 15, and the fourth crank 16. There are no restrictions on the installation order of the cranks. It is only necessary to install the first crank 13 of one of the two adjacent connecting frames 10 and the third crank 15 of the other connecting frame 10 on the same connecting member 19, and to install the fourth crank 16 of one of the two adjacent connecting frames 10 and the second crank 14 of the other connecting frame 10 on the same connecting member 19, so that the assembled connecting frames 10 can achieve synchronous opening or closing.

[0057] In the above embodiment, the length of the external threaded sleeve 26 is less than half the depth of the threaded hole 22, thereby ensuring that the two external threaded sleeves 26 installed on the same rotating ring 20 can be fully installed, and there is no need to loosen the rotating bolt installed earlier when installing the rotating bolt installed later.

[0058] Furthermore, the outer periphery of the limiting rod 11 is a smooth surface, which facilitates the arbitrary extension and retraction adjustment of the installation spacing of multiple connecting plates 1 through the adjustment component without obstruction; wherein, the limiting rod 11 is provided with multiple segments, and the adjacent ends of two adjacent segments of the limiting rod 11 are threadedly connected, which can splice the limiting rod 11 to a suitable length according to the installation length of the connecting plate 1, so as to avoid the limiting rod 11 being too long or too short and affecting the normal installation of the subsequent connecting plate 1.

[0059] Furthermore, the mounting bracket 5 includes a side support plate 29, a fixing plate 31, and a locking bolt 33. One end of the side support plate 29 is fixedly installed on the bottom of the connecting plate 1, and the other end of the side support plate 29 has a mounting hole 30. One end of the fixing plate 31 is fixedly installed on the building wall, and the other end of the fixing plate 31 has a strip-shaped through groove 32. One end of the screw of the locking bolt 33 passes through the strip-shaped through groove 32 and the mounting hole 30 in sequence, and extends to the outside of the mounting hole 30 where a locking nut 34 is threaded. This allows the installation angle of the wedge block 35 to be rotated and adjusted according to the design angle of the tile after the fixing plate 31 is installed on the building wall. In actual operation, the installation angle of the wedge block 35 can be rotated and adjusted simply by loosening the locking nut 34. After adjustment, the locking nut 34 is locked onto the locking bolt 33.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any modifications or alterations made by those skilled in the art without departing from the scope of the technical solution of the present invention using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
