Description

Technical Field

[0001] The invention relates to the technical field of building roofs, and more particularly to a special-shaped adjustable metal roof system and a construction method. Background Art

[0002] The roof structure is a key component of the top of the building. It not only provides shelter and protection for the building, but also undertakes functions such as waterproofing, heat preservation, thermal insulation, and drainage. Among them, metal roofs are widely used in various types of buildings, such as industrial plants, commercial buildings, public facilities, and residences due to their durability, lightness, and aesthetics. The metal roof is mainly composed of a frame and a panel structure. The frame is fixed to the building surface through various steel frames, and the panel is installed on the frame through the mounting structure to form a complete roof system.

[0003] Among them, the skeleton structure needs to be designed according to the building surface. The skeleton structure is assembled by various criss-crossing keel structures. For the conventionally designed flat roof structure, the keel structure can adopt a fixed-shape frame structure, such as a rectangular or triangular frame. The docking points of each keel are fixed in shape, and can be fixedly connected with a standardized node structure, and the keel can be fixed by bolts or welding.

[0004] However, for some roof structures with special building surface shapes, different areas require different frame structure shapes. For example, in some frame structures, keel structures distributed in different directions will converge to the same node.

DETAILED DESCRIPTION

[0039] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0040] Refer to the instruction manual Figures 1 to 13 , a special-shaped adjustable metal roof system, including roof components and construction auxiliary components, refer to the attached manual Figures 1 to 3 The roof assembly includes a node docking plate 1, a keel rod 2 (such as an aluminum alloy round tube keel) and a panel structure 3 (such as a metal roof panel). The node docking plate 1 includes a fixed plate 11 and an extrusion plate 12. The fixed plate 11 is fixedly installed on the roof through an installation structure. Its actual installation position and installation angle depend on the specific position. This embodiment takes the horizontal installation of the fixed plate 11 as an example. Therefore, the upper and lower and horizontal mentioned later are based on this installation method. An annular rolling groove 13 is provided between the fixed plate 11 and the extrusion plate 12. The cross-sectional shape of the annular rolling groove 13 is circular, and an accommodating seam is provided at the edge of the fixed plate 11 and the extrusion plate 12;

[0041] Both ends of the keel rod 2 are provided with ball heads 21, and the ball diameter of the ball head 21 is the same as the diameter of the circular cross-section of the annular rolling groove 13. The ball head 21 is connected to the keel rod 2 through a thin rod member 22. When the keel rod 2 is docked with the node docking plate 1, the ball head 21 is located in the annular rolling groove 13, and an extrusion plate pressure adjusting member 15 is provided on the extrusion plate 12. The extrusion plate pressure adjusting member 15 is used to drive the extrusion plate 12 to be close to the fixed plate 11 and to squeeze the ball head 21 to fix the ball head 21, wherein the thin rod member 22 is located in the accommodating gap between the extrusion plate 12 and the fixed plate 11, and the width of the accommodating gap is greater than the diameter of the thin rod member 22.

[0042] The panel structure 3 is fixedly connected to the keel rod 2 through a mounting member, for example, by bolts and nuts, and a through portion 14 is fixedly connected to the fixing plate 11, and the through portion 14 is arranged through the extrusion plate 12. Figure 3 The extrusion disk pressure regulating member 15 is arranged on the through-portion 14, and the extrusion disk pressure regulating member 15 is located at the top of the fixed disk 11, wherein a thread can be arranged on the outside of the through-portion 14, and the extrusion disk pressure regulating member 15 can select a nut structure, and then by rotating the extrusion disk pressure regulating member 15, the extrusion disk 12 can be squeezed, and then all the ball heads 21 can be fixed, and each keel rod 2 can be fixed indirectly.

[0043] During actual construction, each fixing plate 11 is first fixedly installed on the concrete structure of the building roof (it can also be installed on the corresponding truss or other steel structure), and then the extrusion plate 12 is installed on the fixing plate 11. Initially, the extrusion plate 12 is not tightened, so that there is enough space between the extrusion plate 12 and the fixing plate 11 to allow the ball head 21 to enter the annular rolling groove 13, and then each keel rod 2 is docked with the node docking plate 1, that is, each keel rod 2 is placed according to its position and angle, and the ball head 21 is inserted into the fixing plate 11 and the extrusion plate 12, so that the ball head 21 is located in the annular rolling groove 13, and after all the keel rods 2 at the same node are placed After that, gradually adjust the extrusion plate pressure adjustment piece 15 to gradually apply pressure to the extrusion plate 12, first drive the extrusion plate 12 to contact the ball head 21 for initial limiting, and then fine-tune the angle and position of each keel rod 2 according to actual needs. At this time, the extrusion plate 12 does not apply force to the ball head 21, but only reduces the accommodation gap between the fixed plate 11 and the extrusion plate 12 to prevent the ball head 21 from slipping out. Therefore, each ball head 21 can move relatively to achieve adjustment of the keel rod 2. After all the keel rods 2 are adjusted, continue to tighten the extrusion plate pressure adjustment piece 15 to make the extrusion plate 12 completely squeeze the ball head 21, thereby achieving the squeezing and fixing of the ball head 21.

[0044] Among them, the thin rod 22 can be selected as a threaded rod structure and connected to the keel rod 2 through threads. In actual use, the distance from the ball head 21 to the keel rod 2 can also be adjusted, and then the connection length of the keel rod 2 can be fine-tuned according to the actual installation situation to adapt to different installation requirements of the keel rod 2.

[0045] It should be noted that the roof assembly provided in this embodiment can realize multi-directional and multi-angle adjustment of the keel rod 2 due to the high adjustment freedom of the ball head 21 in the annular rolling groove 13. Therefore, for keel frames of different shapes, the corresponding node positions and the arrangement of the keel rods 2 can be selected, and the fixed plate 11 can be used for combination and connection, so as to combine more special-shaped roof structures. The keel rods 2 converging in multiple directions are uniformly fixed to the node docking plate 1 through the ball head 21, which solves the problem of difficult keel convergence. At the same time, since the universal plate is grooved all around, the convergence direction of the keel is not limited, and the construction error of the aluminum alloy round tube keel can be adjusted to a certain extent. The same node docking plate 1 can connect keel rods 2 of different numbers and directions. Therefore, the node docking plate 1 can be designed as a standard structure and mass-produced, which can adapt to more scenarios, improve the overall construction efficiency of the roofing system, and reduce the production cost of special-shaped roof structures.

[0046] In the above embodiment, during actual assembly, the number of node docking plates 1 and keel rods 2 are relatively large, and the keel rods 2 in some areas are not easy to place. During the actual assembly process, it is necessary to constantly adjust the position of each keel rod 2. However, the number of keel rods 2 connected to some node docking plates 1 is large. During adjustment, if the pressure of the extrusion plate 12 is relatively large, the ball heads 21 are squeezed relatively tightly and are not easy to move. If the pressure of the extrusion plate 12 is relatively small, all the ball heads 21 are relatively loose. When adjusting one of the keel rods 2, the remaining keel rods 2 may shake relatively, making it difficult to adjust them at the same time, affecting the construction efficiency. For this reason, the present embodiment provides a construction auxiliary component for assisting the construction of roof components. For details, refer to the attached manual. Figures 5 to 8The construction auxiliary component includes an installation docking frame 4 and a keel rod positioning frame 5. The installation docking frame 4 is used to dock with the fixing plate 11 to achieve connection with the fixing plate 11, ensuring that the construction auxiliary component can be fixed at the corresponding node position. The keel rod positioning frame 5 is used to position the thin rod 22, thereby achieving auxiliary support when adjusting the keel rod 2. The installation docking frame 4 includes a connecting frame 41, which is used to dock with the penetration portion 14. A docking connector 43 is provided in the connecting frame 41. The docking connector 43 is used to be fixedly connected to the penetration portion 14, and an annular guide rail is provided on the connecting frame 41. 42, the keel rod positioning frame 5 includes a pressure frame 51, and a base structure 52 is installed at the bottom end of the pressure frame 51. The keel rod positioning frame 5 also includes a slide 54, and the slide 54 is slidably installed on the annular guide rail 42. A fastening structure is provided between the slide 54 and the annular guide rail 42, which is used to fix the annular guide rail 42 after adjusting the position of the annular guide rail 42 (such as a fastening screw structure). The base structure 52 is a C-shaped structure, and a slot for engaging with the thin rod 22 is provided inside the base structure 52. An opening is provided on one side of the base structure 52, and the opening is used to accommodate the thin rod 22 into the slot.

[0047] For further information, please refer to the attached manual. Fig.11 An elastic fastening member 521 is fixedly connected in the slot of the socket structure 52. The elastic fastening member 521 is a C-shaped structure, and the elastic fastening member 521 is arranged to fit the local circumferential surface of the thin rod 22. An elastic protrusion structure is arranged at a position corresponding to the opening on the inner wall of the elastic fastening member 521. When the thin rod 22 is inserted into the slot, the above-mentioned elastic protrusion structure forms a reverse blockage in the uncovered area of ​​the thin rod 22, thereby providing corresponding reverse restriction for the thin rod 22.

[0048] Refer to the instruction manual Figure 6 and Figure 7 An auxiliary pressure plate 44 is provided at the bottom of the connecting frame 41. The auxiliary pressure plate 44 is connected to the connecting frame 41 through a sliding rod. The sliding rod and the connecting frame 41 are slidably matched. An elastic member (such as a spring) is provided between the sliding rod and the connecting frame 41. The elastic member is used to provide downward pressure to the auxiliary pressure plate 44. After the connecting frame 41 is assembled, the auxiliary pressure plate 44 can provide downward elastic pressure to the extrusion plate 12. For the smaller and lighter keel rod 2, the above-mentioned elastic pressure can be used to provide auxiliary fixation.

[0049] Among them, the keel rod positioning frame 5 is arranged corresponding to the keel rod 2, and the number of the keel rod positioning frame 5 can be the same as the number of the keel rod 2, or more than the number of the keel rod 2. Under the action of the sliding seat 54, the keel rod positioning frame 5 can adjust the position arbitrarily around the connecting frame 41. Therefore, when the number of the keel rod positioning frame 5 is more than the number of the keel rod 2, the required number of keel rod positioning frames 5 can be selected and their positions can be adjusted.

[0050] It should be noted that, please refer to the attached manual Figure 6 and Figure 7 A threaded hole is provided at the center of the through-portion 14, and the docking connector 43 is a bolt structure. During installation, the connecting frame 41 is docked on the through-portion 14, and the docking connector 43 is tightened to be threadedly connected with the through-portion 14, so that the connecting frame 41 can be fixed without affecting the adjustment of the extrusion disk 12. In order to facilitate the control of the docking connector 43, the top end of the docking connector 43 can be extended upward, and a knob or handle can be provided for easy operation.

[0051] Furthermore, the keel rod positioning frame 5 also includes a pressure frame pressure adjustment member 53, which is arranged on a slide seat 54. The pressure frame 51 is vertically slidably arranged on the slide seat 54. The pressure frame pressure adjustment member 53 adjusts the upper and lower positions of the clamping structure 52 and the vertical pressure of the clamping structure 52 on the thin rod 22 by adjusting the upper and lower positions of the pressure frame 51. When used specifically, except for the keel rod 2 that needs to be adjusted and does not need to be fixed by the keel rod positioning frame 5, the remaining keel rods 2 are all auxiliaryly supported by the keel rod positioning frame 5 to be fixed. Specifically, when the keel rod positioning frame 5 is in an active state, the height of the keel rod positioning frame 5 is adjusted until the clamping structure 52 corresponds to the keel rod 2, so that the corresponding The thin rod 22 of the keel rod 2 is inserted into the socket structure 52, so that the thin rod 22 and the socket structure 52 are relatively fixed, and then the pressure frame 51 is driven to apply pressure downward, so that the socket structure 52 forms a downward pressure on the thin rod 22, and then the ball head 21 is pressed tightly against the inner wall of the annular groove 13 in the fixed plate 11, so as to temporarily fix the ball head 21 (because the ball head 21 is tightly fitted with the annular groove 13 on the fixed plate 11, the keel rod 2 can be restricted along its length direction, and the restrictions in other directions are all restricted by the socket structure 52. Among them, although an opening is provided on the socket structure 52, in actual use, the opening can be adjusted to a corresponding position so that it does not affect the support of the thin rod 22).

[0052] It should be noted that the pressure regulating member 53 of the pressure frame can adopt a threaded rod structure, and a sleeve block structure that threadably cooperates with the pressure regulating member 53 of the pressure frame is fixedly installed on the pressure frame 51. The pressure regulating member 53 of the pressure frame is rotatably installed on the slide 54. Then, by rotating the pressure regulating member 53 of the pressure frame, the height of the clamping structure 52 can be adjusted and downward pressure can be applied to the clamping structure 52. In addition, the pressure regulating member 53 of the pressure frame can also adopt automated equipment, such as a hydraulic cylinder structure.

[0053] In the above embodiment, if the roof assembly is in a planar structure as a whole, each keel rod 2 is substantially parallel to the radial line of the node docking plate 1, that is, the keel rod 2 has no vertical angle change. Figure 6At this time, the card seat structure 52 can be directly fixed on the bottom of the pressure frame 51, with high support strength and simple structure. However, for different special-shaped roofs, the same set of node docking plates 1 may need to be connected to keel rods 2 with different angles (upward and downward tilt and left and right tilt). Therefore, the corresponding card seat structure 52 also needs to be adaptively adjusted. For details, refer to the attached manual. Figures 9 to 11 The bottom of the pressure frame 51 is rotatably mounted with a rotating rod 511, and the bottom of the rotating rod 511 is provided with a rotating seat 512, which is fixedly mounted on the card seat structure 52. The bottom end of the rotating rod 511 is rotatably matched with the rotating seat 512, so that the card seat structure 52 can have more adaptable directions, so as to adapt to the thin rod 22 with different angle requirements. For details, please refer to the attached manual. Fig. 9 and Fig.10 Status shown.

[0054] Based on the above embodiment, the rotation between the above-mentioned rotating rod 511 and the pressure frame 51, and the rotation between the rotating seat 512 and the rotating rod 511 can be provided with a damping structure to generate resistance between the above-mentioned structures, so as to provide certain support for the ball head 21 after the adjustment is completed. For example, when the angle of the keel rod 2 is relatively special, other parts of the keel rod 2 lack sufficient support, and the gravity of the keel rod 2 itself is relatively large, the above-mentioned friction resistance is not enough to provide corresponding fixation. For this reason, while providing sufficient degrees of freedom for the socket structure 52, this embodiment also provides the following two fixing schemes for pre-fixing the ball head 21.

[0055] Solution 1: A fastening assembly, such as a set screw, is provided between the rotating rod 511 and the pressure frame 51, and between the rotating rod 511 and the rotating seat 512. The two sets of fastening assemblies are respectively used to fix the rotation between the rotating rod 511 and the pressure frame 51, and the rotation between the rotating rod 511 and the rotating seat 512. Therefore, after the base structure 52 cooperates with the thin rod 22 and adjusts the corresponding auxiliary support posture, the set screw is controlled to fix the above structure to improve the stability of the auxiliary support.

[0056] Solution 2: The keel rod positioning frame 5 also includes a ball head expansion drive assembly, which includes an input tube 522 and an output tube 523. A hollow cavity is provided in the ball head 21, and a flow channel 23 extending into the ball head 21 and folded back into the thin rod 22 is provided in the thin rod 22. The input tube 522 and the output tube 523 are fixedly installed on the base structure 52. The thin rod 22 is provided with two groups of docking holes 24 for docking with the input tube 522 and the output tube 523, respectively. The two groups of docking holes 24 are connected to the head end and the tail end of the flow channel 23, respectively, and the thin rod 22 is engaged with the base. When in structure 52, the two groups of docking holes 24 are docked with the input pipe 522 and the output pipe 523 respectively. The ball head expansion drive assembly also includes a hot liquid source and a pump structure. The hot liquid source includes a liquid source and a liquid heater. The liquid source, the liquid heater and the pump are all arranged in the connecting frame 41. The pump is connected to the input pipe 522 through a pipeline, and the output pipe 523 is connected to the liquid source through a pipeline, that is, the liquid source is heated by the liquid heater, and the hot liquid source is transported to the circulation channel 23 by the pump, so that the high-temperature liquid flows through the inner cavity of the ball head 21, heats the ball head 21, and expands it.

[0057] During specific use, the ball heads 21 of all the keel rods 2 are first installed into the annular rolling groove 13, and the extrusion disk 12 is controlled to contact the ball heads 21 and apply initial pressure to each ball head 21. Under this initial pressure state, each ball head 21 can move under human power. For the keel rod 2 that needs to be fixed, it is only necessary to dock the corresponding socket structure 52, and then heat and expand the corresponding ball head 21, thereby increasing the volume of the ball head 21, increasing the extrusion force between the ball head 21 and the inner wall of the annular rolling groove 13, and increasing the friction between the two. After all the keel rods 2 have been adjusted, the extrusion disk pressure adjustment member 15 can be tightened to apply a fixing pressure to the extrusion disk 12, so that all the keel rods 2 are finally fixed, and then the mounting docking frame 4 and the keel rod positioning frame 5 at this position can be removed, and the construction and adjustment of the next position can be carried out, thereby realizing the fixation of the corresponding ball head 21. This scheme does not require the sliding seat 54, the rotating rod 511 and the rotating seat 512 to be fixed and adjusted, and the operation steps are relatively simple.

[0058] In addition, based on the above-mentioned expansion and fixation principle, in addition to thermal expansion, a pressure expansion solution can also be adopted, that is, a number of smaller airbag structures are set on the surface of the ball head 21, and corresponding flow channels are set in the ball head 21 and the thin rod 22, and then with the air pump structure, air pressure is applied to the airbag to make it expand, and reverse pressure can also be applied to the ball head 21 to fix it.

[0059] In the above-mentioned scheme one, the operation is relatively complicated, but it is suitable for some scenarios where some keel rods 2 have been installed first and these keel rods 2 need to be assisted in fixation, and other keel rods 2 need to be installed. At this time, the extrusion plate 12 is far away from the fixing plate 11, and a sufficient accommodation gap needs to be maintained. Therefore, the annular rolling groove 13 has less restriction on the ball head 21, and it can only be assisted in fixation by the pressure frame 51 and the seat structure 52. Therefore, scheme one can be adopted. As for scheme two, although the operation is simple, it is more suitable for the scenario where the ball heads 21 of all keel rods 2 are installed in the annular rolling groove 13 and then adjusted. However, the above-mentioned schemes one and two do not conflict in structural design and can exist at the same time. Therefore, the corresponding scheme can be applied according to actual conditions.

[0060] It should be noted that since the node docking plate 1 can be designed as a standard structure as a whole, the corresponding ball head 21 and thin rod 22 of the keel rod 2 can also be set as a standard structure. Therefore, the required installation docking frame 4 and keel rod positioning frame 5 can also be set as a standard structure. Therefore, a set of installation docking frame 4 and keel rod positioning frame 5 can be used repeatedly, which is more practical, has a lower overall cost, and the constructed roof components have higher precision.

[0061] Refer to the instruction manual Fig.14 The present invention also provides a construction method of a special-shaped adjustable metal roofing system, comprising the following steps:

[0062] Step 1: fix the fixing plate 11 at the corresponding position of the building roof, and assemble the extrusion plate 12 with the fixing plate 11;

[0063] Step 2: insert the ball heads 21 at both ends of the keel rod 2 to be connected into the corresponding annular rolling grooves 13 between the fixed plate 11 and the extrusion plate 12, and adjust the extrusion plate pressure adjustment member 15 to make the extrusion plate 12 contact with the ball heads 21;

[0064] Step 3: Install the connecting frame 41 on the penetration portion 14 through the docking connector 43;

[0065] Step 4: fine-tune the direction and position of the keel rod 2. During the fine-tune, the keel rod positioning frame 5 is used to provide auxiliary support for the keel rods 2 that do not need to be adjusted, that is, the pressure frame 51 is controlled to move to the corresponding position of the keel rod 2 that does not need to be adjusted, and the holder structure 52 is engaged with the thin rod 22 of the corresponding keel rod 2 to provide auxiliary support for the keel rod 2;

[0066] Step 5. Adjust the angle and position of each keel rod 2 in turn. After completion, control the extrusion plate pressure adjustment member 15 so that the extrusion plate 12 applies a fixed pressure to the ball head 21, so that each ball head 21 is in a fixed state, and then remove the installation docking frame 4 and the keel rod positioning frame 5 to proceed to the next node operation.

[0067] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
