Description

Technical Field

[0001] The invention relates to the technical field of building structures, and more particularly to a steel structure metal tile slope roof and an installation method thereof. Background Art

[0002] The roof structure refers to the part of the building's top that is used to cover and protect the interior of the building from the weather. It not only plays a role in waterproofing, heat insulation, and thermal insulation, but is also an important element in building design.

[0003] Among them, in some building structures, such as steel-structured factories and scenarios where the original flat roof is converted to a sloped roof, steel-structured metal tile sloped structure is often used, that is, a steel frame is built on the top of the building (usually composed of steel beams and steel columns, which are connected together by welding or bolts to form a stable frame structure). Purlins (or rafters) are laid on top of the steel frame. They are important components for supporting the roof panels and are responsible for transferring the load of the roof panels to the main structure. Finally, the roof tile structure is laid and fixed on the purlins.

[0004] In order to improve production efficiency and installation efficiency, some buildings need to use large roof tile structures, and in order to ensure the strength and service life of the tile surface, metal tile structures are usually used. For example, after the steel structure on the top of the building is completely built, the metal tiles can be transported to the top of the building. However, in order to improve the protective effect of metal tiles and reduce the number of joints, some buildings will choose to directly lay metal tile structures with larger single areas. For the laying of such tiles, hoisting equipment is required (for color steel tiles, high-altitude color steel tile forming equipment can be used directly, but for higher equipment, high-altitude color steel tile forming equipment cannot meet the requirements, and can only be processed and formed on the ground and then lifted and transported using hoisting equipment).

[0005] However, for large buildings, the total amount of roof tiles required is large, and the position of the lifting equipment is not suitable to be changed. Therefore, in the prior art, in order to facilitate the movement and laying of metal tiles on steel structures, as well as the inspection and maintenance of the roof after the construction of the building structure is completed (such as snow removal in winter), a set of mobile frame structures (auxiliary frames, auxiliary slope roof system installation and subsequent various maintenance operations) will be added to the roof structure, so that during roof construction, a large number of metal tiles can be lifted together onto the mobile frame structure, and the mobile frame structure can drive the roof tiles to the corresponding position, and then the workers will remove the roof tiles and lay them on the steel structure, thereby reducing the number of lifting times of the lifting equipment and there is no need to change the position of the lifting equipment.

[0006] Among them, since the metal tiles need to be stored on a mobile frame structure first, they need to be removed simultaneously by multiple workers during the actual laying. However, since it is an aerial operation, it is difficult to add large-scale operating equipment. When the workers are operating, different workers have different holding points. For longer roof tile structures, when multiple workers cooperate to lift them, it is easy for them to bend due to the different forces applied by each worker. In severe cases, it may even cause damage to the metal tiles. In addition, the elastic force of the metal tiles can easily push back on the workers, which is dangerous. Summary of the invention

[0014] In a preferred embodiment, the bottom of the pointed-angle plug is set as an inclined portion, the top of the pointed-angle plug is set as a straight shape, and one end of the pointed-angle plug corresponding to the roof tile is formed as a pointed corner portion.

DETAILED DESCRIPTION

[0031] 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.

[0032] Refer to the instruction manual Figures 1 to 10 A steel structure metal tile slope roof comprises a steel structure system 1, roof tiles 2 and an auxiliary frame 3, the roof tiles 2 are laid and installed on the steel structure system 1, the auxiliary frame 3 is slidably installed on the steel structure system 1, and the auxiliary frame 3 is slidably arranged along the laying direction of the roof tiles 2; Specifically, the steel structure system 1 includes a steel frame 11 and purlins 12. The steel frame 11 is built on the top of the building. The purlins 12 are arranged in multiple groups. The multiple groups of purlins 12 are arranged in parallel on the steel frame 11 and fixedly installed on the steel frame 11. The roof tiles 2 are fixedly installed on the purlins 12, and a single roof tile 2 spans across multiple purlins 12. The purlins 12 are used to improve the support strength of the roof tiles 2. In order to facilitate drainage, the overall structure of the steel structure system 1 is sloped. It should be noted that both ends of the auxiliary frame 3 are provided with a walking mechanism 31, and the walking mechanism 31 is a guide wheel structure, and the purlin 12 can be used as a guide rail to guide the walking mechanism 31. Based on this scheme, since the purlin 12 is no longer exposed after the roof tile 2 is installed, if the subsequent movement of the auxiliary frame 3 is to be guaranteed, two walking mechanisms can be set on the auxiliary frame 3, one directly cooperates with the purlin 12, and the other directly rolls with the surface of the roof tile 2 after the roof tile 2 is installed, but the cooperation position needs to be above the purlin 12. In addition, a guide rail structure can be separately added to the steel frame 11 to cooperate with the walking mechanism 31 to complete For the movement guidance and drive of the auxiliary frame 3, the added guide rail structure needs to ensure that it will not be covered by the roof tiles 2, and a separate support and shielding structure is set for the guide rail structure. After the laying of the roof tiles 2 is completed, the guide rail structure is still exposed and does not affect the movement of the auxiliary frame 3 during the later maintenance. Among them, the walking mechanism 31 can be manually pushed or automatically driven by a corresponding drive motor as required. A placement area 13 is set at the edge position of the steel structure system 1, and the steel structure at the placement area 13 is reinforced so that when the auxiliary frame 3 is not in use, the auxiliary frame 3 can be moved to the placement area 13 for storage.

[0033] Furthermore, two groups of limiting guardrails 32 are provided on the auxiliary frame 3. Under the limiting position of the two groups of limiting guardrails 32, a storage area can be formed on the auxiliary frame 3 to facilitate the simultaneous storage of multiple groups of roof tiles 2. After the steel structure system 1 is completely built, the relevant structures of the auxiliary frame 3 are hoisted onto the steel structure system 1 for assembly using a lifting device. When it is necessary to lay roof tiles 2, multiple groups of roof tiles 2 can be stacked and placed on the ground. After bundling, the multiple groups of roof tiles 2 are hoisted onto the auxiliary frame 3 at one time by the lifting device, and the auxiliary frame 3 is temporarily supported. The auxiliary frame 3 is then driven to gradually move along the laying direction on the steel structure system 1, and the operating workers take out the roof tiles 2 on the auxiliary frame 3 one by one, and then fix them on the steel structure system 1 until all the roof tiles 2 are installed. Then, multiple groups of auxiliary frames 3 can be hoisted at one time, without the need to constantly adjust the position of the hoisting equipment, and the number of times the hoisting equipment is used can also be reduced, especially for equipment with a higher height, which can save a lot of hoisting operations.

[0034] In the above embodiment, since the constructed steel structure system 1 is in a hollow state, the auxiliary frame 3 can not only carry the roof tiles 2 during installation and construction, but also increase space to store other related equipment, such as welding machines, safety ropes, etc.

[0035] In order to facilitate the workers to take and place the roof tiles 2, the present embodiment also provides the following technical solutions: multiple groups of pick-up and place machines 4 are arranged on the limit guardrail 32, and the pick-up and place machines 4 include a main swing arm 41, a secondary swing arm 42 and a grabbing frame 43. The main swing arm 41 is rotatably mounted on the limit guardrail 32, the secondary swing arm 42 is rotatably mounted on the end of the main swing arm 41, and the grabbing frame 43 is mounted on the end of the secondary swing arm 42 away from the main swing arm 41. The main swing arms 41 are fixedly connected by a group of synchronization rods 5, and the secondary swing arms 42 are fixedly connected by another group of synchronization rods 5, thereby ensuring that the groups of pick-up and place machines 4 can be synchronized. Operation, a grabbing fixture 44 is provided at the bottom of the grabbing frame 43, and the grabbing fixture 44 is used to grab and fix the roofing tiles 2. Specifically, since most of the roofing tiles 2 are thin and the surface of the metal structure roofing tiles 2 is relatively smooth, a commonly used vacuum suction cup structure can be used as the grabbing fixture 44 to grab and fix the roofing tiles 2. For some thicker and heavier roofing tiles 2, there is enough space at their edges to be clamped. Therefore, for such roofing tiles 2, the grabbing fixture 44 can also use a clamping claw structure. In addition, the grabbing fixture 44 can also use other types of grabbing structures.

[0036] It should be noted that in actual use, please refer to the instructions attached. Figures 4 to 5 , the worker can first drive the main swing arm 41 and the grabbing frame 43 to flip to the top of the auxiliary frame 3, so that the grabbing fixture 44 contacts and absorbs the uppermost roof tile 2 in the auxiliary frame 3, and then multiple workers at least two people jointly lift the roof tile 2 and operate the corresponding main swing arm 41 and the auxiliary swing arm 42 to swing, so that the roof tile 2 is flipped from the inside of the auxiliary frame 3 to the outside of the auxiliary frame 3, and then the roof tile 2 is lowered to the purlin 12 for installation one by one. Since the main swing arms 41 and the auxiliary swing arms 42 are relatively fixedly connected, when the roof tile 2 is lifted, the overall shape of the roof tile 2 is relatively stable, and no large deformation will occur, thereby causing no damage to the roof tile 2. In particular, it can avoid the influence caused by the different operating strengths of each worker, and can improve the convenience of taking and placing the roof tile 2.

[0037] Further, in order to improve the application scope of the pick-and-place machine 4, this embodiment also provides the following technical solutions, which are specifically referred to in the appendix of the specification. Figure 4 The main swing arm 41 includes an outer rod 411 and a telescopic rod 412. The outer rod 411 is rotatably connected to the top of the roof tile 2. The telescopic rod 412 is slidably set in the outer rod 411. The auxiliary swing arm 42 is rotatably installed on the telescopic rod 412, so that the length of the main swing arm 41 can be adjusted, so as to better adjust the position of the grabbing frame 43 for grabbing.

[0038] Furthermore, in the above-mentioned embodiment, the grabbing frame 43 can be directly fixedly connected to the auxiliary swing rod 42, but in order to improve the operating performance of the pick-and-place machine 4, a rotational connection method can also be adopted, that is, the grabbing frame 43 is rotatably installed on the auxiliary swing rod 42, and each group of grabbing frames 43 is fixedly connected by another group of synchronization rods 5. Specifically, a first group of synchronization rods 5 are arranged through the limiting guardrail 32, and this group of synchronization rods 5 are rotationally matched with the limiting guardrail 32, and each group of outer sleeve rods 411 are directly fixedly connected to this group of synchronization rods 5. Similarly, a second group of synchronization rods 5 are arranged through each group of telescopic rods 412, and this group of synchronization rods 5 are rotationally connected to the telescopic rods 412, and each auxiliary swing rod 42 is fixedly connected to this group of synchronization rods 5. A third group of synchronization rods 5 are arranged through each group of auxiliary swing rods 42, and this group of synchronization rods 5 are rotationally matched with the auxiliary swing rod 42, and each grabbing frame 43 is fixedly installed on this group of synchronization rods 5.

[0039] It should be noted that the structure of the picking and placing mechanism 4 can be disassembled or retained after the overall installation of the sloping roof is completed, so as to facilitate the replacement of the roof tiles 2 at a later time. In order to make the operation more labor-saving for workers, torsion springs are arranged between the outer rod 411 and the limiting guardrail 32, between the auxiliary rocker arm 42 and the telescopic rod 412, and between the grabbing frame 43 and the auxiliary rocker arm 42. The torsion spring is used to provide a force opposite to the gravity of the roof tiles 2 to each structure after the picking and placing mechanism 4 grabs the roof tiles 2. An elastic reset structure, such as a spring, is also arranged between the telescopic rod 412 and the outer rod 411 to ensure that the main rocker arm 41 has an elastic force to reset to the middle when extending or shortening, thereby making the operation more labor-saving for workers.

[0040] In addition, for the rotation and telescopic sliding of the above-mentioned structures, an automatic control structure, such as a driving motor, a telescopic cylinder, etc., can be directly set according to needs.

[0041] Due to different building requirements, some buildings directly use corrugated colored steel tiles with roof tiles 2. There are many raised corrugations on such roof tiles 2. Figure 4 Therefore, when stacking, due to the influence of the thickness of the roofing tiles 2, the corrugations between the upper and lower layers of roofing tiles 2 cannot be completely fitted, and gaps can be left. Some buildings require the use of relatively straight smooth roofing tiles 2, refer to the attached manual Figure 3 and Figure 7Since this type of roofing tile 2 is relatively flat, when actually stacked, the upper and lower layers of roofing tiles 2 are closely attached to each other. Under the influence of gravity, the air between the two adjacent layers of roofing tiles 2 is squeezed out to form a vacuum state. Therefore, it is easy to form a large suction force between the upper and lower layers of roofing tiles 2. For thinner roofing tiles 2, it is difficult to grasp their edges using a clamping claw structure, and the roofing tiles 2 can only be adsorbed and fixed with the help of a vacuum suction cup as a grasping fixture 44. Therefore, when workers actually operate, it is easy to encounter difficulties in grasping and lifting the roofing tiles 2, or lift two or three layers of roofing tiles 2 at a time, which will affect the installation efficiency. For this reason, this embodiment The example also provides the following scheme. Specifically, an edge starting component is provided on the limiting guardrail 32, and the edge starting component includes an edge starting lifting frame 6. The edge starting lifting frame 6 is slidably installed on the limiting guardrail 32, and a plurality of groups of sharp corner plugs 61 are provided on one side of the edge starting lifting frame 6 corresponding to the inner side of the auxiliary frame 3. An active cavity 62 is opened in the edge starting lifting frame 6. The sharp corner plug 61 is slidably set in the active cavity 62. An elastic member 63 is provided between the sharp corner plug 61 and the active cavity 62. The elastic member 63 is used to provide an elastic force for the sharp corner plug 61 to move outward. The edge starting component also includes a lifting drive component 7, and the lifting drive component 7 is used to drive the edge starting lifting frame 6 to move up and down.

[0042] For further information, please refer to the attached manual. Fig.10 The bottom of the pointed-angle plug 61 is set as an inclined portion 611, the top of the pointed-angle plug 61 is set as a straight shape, and one end of the pointed-angle plug 61 corresponding to the roof tile 2 is formed as a pointed corner portion 612.

[0043] In actual use, when it is necessary to take out the upper roofing tile 2, the edge lifting frame 6 is first driven to rise, so that the pointed corner plug 61 moves upward around the roofing tile 2, and the pointed corner plug 61 is inserted into the gap between the two adjacent layers of roofing tiles 2 under the elastic force of the elastic member 63. However, for the roofing tiles 2 on the bottom layer, there are more roofing tiles 2 on the top and the gravity is greater. The pointed corner plug 61 will not be inserted too deep, nor will the edge of the roofing tile 2 be lifted. However, when the edge lifting frame 6 gradually moves to the roofing tiles 2 on the upper layer, since there is no other pressure above the upper roofing tiles 2, the pointed corner portion 612 of the pointed corner plug 61 can be inserted between the upper and lower roofing tiles 2. The gap between the upper and lower layers of roof tiles 2 is deeper, and when the edge lifting frame 6 continues to rise, the edge of the roof tile 2 is bent and lifted upward, so that the gap at the edge of the upper and lower layers of roof tiles 2 is increased. Therefore, external air can gradually enter between the upper and lower layers of roof tiles 2 along the gap, eliminating the "vacuum" state mentioned above, and thus it is more labor-saving when lifting the upper layer of roof tiles 2. After the upper layer of roof tiles 2 is taken away, the edge lifting frame 6 can be temporarily driven to descend a distance. At this time, under the action of the inclined portion 611, the pointed corner plug 61 will retract without affecting the descent of the edge lifting frame 6, waiting for the next time to grab the roof tile 2, and then drive the edge lifting frame 6 to move up again.

[0044] It should be noted that in the above embodiment, the lifting drive assembly 7 can adopt an automated control structure, such as a hydraulic cylinder. However, considering the weight reduction of the auxiliary frame 3 and the fact that it is not suitable to set up many devices on the steel structure system 1 in the high-tech area, the lifting drive assembly 7 can also adopt a human-powered device, for example, referring to the attached manual. Fig. 9 The lifting drive assembly 7 includes an active cylinder 71 and a slave cylinder 72, both of which are fixedly mounted on the auxiliary frame 3. An active piston rod 73 is slidably mounted in the active cylinder 71, and the top end of the active piston rod 73 extends to the outside of the active cylinder 71 as an input end. A slave piston rod 74 is slidably mounted inside the slave cylinder 72, and the top end of the slave piston rod 74 is fixedly connected to the starting lifting frame 6. The bottoms of the slave cylinder 72 and the active piston rod 73 are connected to each other, and liquid medium is provided in the slave cylinder 72 and the active piston rod 73.

[0045] Among them, in order to facilitate operation, a pedal 76 can be fixedly installed on the top of the active piston rod 73. In actual use, the pedal 76 is stepped on to press the active piston rod 73 downward, which can increase the liquid pressure in the slave cylinder 72, and then the slave piston rod 74 rises, thereby realizing the upward drive of the side lifting frame 6. After use, the pressure on the pedal 76 is removed, and the side lifting frame 6 will slowly descend under the action of its own weight.

[0046] Further, in order to improve the separation effect of the edge of the top roof tile 2, this embodiment also provides the following technical solutions, for details, refer to the attached manual Fig. 9 and Fig.10The driven piston rod 74 is a hollow structure, and a connecting pipe 75 is fixedly connected to the top of the driven piston rod 74. The connecting pipe 75 is connected to the active chamber 62, and the active chambers 62 in the edge lifting frame 6 are connected to each other. A liquid spraying slit 613 is provided inside the sharp corner plug 61, and the liquid spraying slit 613 is connected to the active chamber 62, and the liquid spraying slit 613 extends to the sharp corner 612. The liquid medium in the active cylinder 71 and the driven cylinder 72 is lubricating oil. When the pedal 76 is stepped on to press the active piston rod 73 downward, a part of the lubricating oil can be sprayed out from the liquid spraying slit 613 under the action of extrusion, and sprayed to the edges and gaps of the upper and lower roof tiles 2 to form lubrication, thereby avoiding friction damage between the sharp corner plug 61 and it. Secondly, since the liquid spraying slit 613 is a narrow slit structure, the spraying amount is limited. Therefore, the driven piston rod 74 can still As it rises, since the edges of the roof tiles 2 between the upper areas will be lifted and bent, during the lifting process, the lubricating oil enters the gap to form a barrier. Therefore, for the second and third layers of roof tiles 2 (from top to bottom), since the lubricating oil is filled at the edges of the gaps in advance, the gap height at the edges of the roof tiles 2 is relatively greater than the height at the center. Therefore, under the filling of the lubricating oil, some air will enter at the edges of the gaps, making it easier to lift the edges of the roof tiles 2 next time. Moreover, due to the presence of the lubricating oil, when the upper and lower layers of roof tiles 2 are still difficult to separate, the workers can push the roof tiles 2 to produce relative movement to increase the probability of the "vacuum" disappearing (the vacuum pressure is in the up and down direction and does not affect the planar movement of the roof tiles 2), while also protecting the edges of the roof tiles 2.

[0047] It should be noted that, each time the lifting frame 6 rises, a little lubricating oil in the slave cylinder 72 will be sprayed out. Therefore, the next time the pedal 76 is stepped on, the rising height of the slave piston rod 74 will be reduced due to the reduction of lubricating oil, which is just adapted to the phenomenon of reduced thickness of the roof tiles 2 on the auxiliary frame 3 after the roof tiles 2 are removed each time. Until the lubricating oil is reduced too much, lubricating oil can be added to the active cylinder 71.

[0048] Refer to the instruction manual Fig.11 The present invention also provides a method for installing a steel structure metal tile slope roof, comprising the following steps: Step 1: build a steel frame 11 on the top of the building, and then install the purlins 12 on the steel frame 11 to form a steel structure system 1; Step 2: hoist the auxiliary frame 3 onto the steel structure system 1 and assemble it so that the walking mechanism 31 cooperates with the corresponding purlin 12; Step 3: hoist the pick-and-place mechanism 4 and the synchronization rod 5 onto the auxiliary frame 3 for assembly; Step 4: Stack and bundle multiple groups of roof tiles 2 on the ground, and hoist them onto the auxiliary frame 3 using hoisting equipment; Step 5: Workers use the pick-and-place machine 4 to take the roof tile 2 out of the auxiliary frame 3 and place it in the area of ​​the corresponding purlin 12 for fixed installation.
