Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building structures, and more particularly, to a steel structure metal tile slope roof and a mounting method thereof. BACKGROUND

[0002] The roof structure refers to the part of the structure on the top of the building for covering and protecting the inside of the building from the weather. It not only plays the role of waterproofing, heat insulation, and thermal insulation, but also is an important element in building design.

[0003] Among them, in some building structures, such as steel structure workshops, and in the scene of rebuilding the slope roof from the original flat roof, steel structure metal tile slope roof structure is often used, that is, a steel skeleton (usually composed of steel beams, steel columns, which are connected together by welding or bolts to form a stable frame structure) is built on the top of the building, on the steel skeleton, purlins (or called rafters) are laid, which are important components for supporting the roof panel and responsible for transmitting the load of the roof panel to the main structure, and finally, the roof tile structure is laid and fixed on the purlins.

[0004] In order to improve the production efficiency and installation efficiency, large roof tile structures are needed in some buildings, and in order to ensure the strength and service life of the tile, metal tile structures are usually used, for example, after the steel structure on the top of the building is completely built, metal tiles can be transported to the top of the building, but in order to improve the protection effect of the metal tile and reduce the number of joints, a single large-area metal tile structure is selected for laying. For the laying of such tiles, hoisting equipment is needed (for color steel tiles, high-altitude color steel tile forming equipment can be directly used, but for higher equipment, high-altitude color steel tile forming equipment cannot be satisfied, and can only be used after being processed on the ground. Hoisting equipment is used for lifting and transporting).

[0005] However, for large buildings, the total amount of roof tiles required is large, and the position of the hoisting equipment cannot be changed, therefore, in order to facilitate the movement and laying of metal tiles on the steel structure, and to facilitate the maintenance and repair of the roof after the completion of the building structure construction (such as snow removal in winter), a set of movable frame structure (auxiliary frame, auxiliary slope roof system installation and subsequent maintenance work) is added to the roof structure, so that a large number of metal tiles can be hoisted to the movable frame structure during the roof construction, and the movable frame structure can drive the roof tiles to move to the corresponding position, and then the workers can take down the roof tiles and lay them on the steel structure, thereby reducing the lifting frequency of the hoisting equipment and eliminating the need to change the position of the hoisting equipment.

[0006] Wherein, since the metal tile needs to be stored on the moving frame structure first, and then taken off by multiple workers at the same time during actual laying, but since it is high-altitude operation, it is difficult to increase large-scale operation equipment, and when workers operate, different workers hold at different points, and for longer roof tile structures, when multiple workers cooperate to lift, it is easy to cause bending due to different forces applied by workers, and in severe cases, the metal tile can even be damaged, and the elastic force of the metal tile is also easy to form a counterthrust on the workers, which has a certain risk.

DETAILED DESCRIPTION

[0039] The following further describes the application in conjunction with the drawings. It is necessary to point out that the following detailed description is only used to further describe the application and cannot be understood as limiting the protection scope of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application according to the above application content.

[0040] Refer to the description attached Figures 1 to 10 A steel structure metal tile sloping roof, comprising a steel structure system 1, roof tiles 2 and an auxiliary frame 3, the roof tiles 2 are installed on the steel structure system 1, the auxiliary frame 3 is slidingly installed on the steel structure system 1, and the auxiliary frame 3 is slidingly arranged along the laying direction of the roof tiles 2;

[0041] Specifically, the steel structure system 1 comprises a steel skeleton 11 and purlins 12, the steel skeleton 11 is built on the top of a building, the purlins 12 are arranged in multiple groups, the multiple groups of purlins 12 are arranged in parallel on the steel skeleton 11 and are fixedly installed with the steel skeleton 11, the roof tiles 2 are fixedly installed on the purlins 12, and a single roof tile 2 spans multiple purlins 12, so that the purlins 12 improve the support strength of the roof tiles 2, wherein the overall structure of the steel structure system 1 is in a slope shape for facilitating drainage;

[0042] It should be noted that the two ends of the auxiliary frame 3 are provided with walking mechanisms 31, which are guide wheel structures, 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 ensured, two types of walking mechanisms can be provided 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 the movement guidance and driving of the auxiliary frame 3. The added guide rail structure needs to be ensured not to be covered by the roof tile 2, and a support and shielding structure is separately provided at the guide rail structure. Because the guide rail structure is still exposed after the laying of the roof tile 2 is completed, it 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 a corresponding driving motor can be provided for automatic driving according to the needs. The steel structure system 1 is provided with a placement area 13 at the edge position, and the steel structure at the placement area 13 is reinforced to facilitate storage of the auxiliary frame 3 when it is not in use.

[0043] Further, two groups of limiting guardrails 32 are provided on the auxiliary frame 3, and under the limiting of the two groups of limiting guardrails 32, a storage area can be formed on the auxiliary frame 3 to store multiple groups of roof tiles 2 at the same time. After the steel structure system 1 is completely built, the related structure of the auxiliary frame 3 is hoisted by a hoisting device to assemble on the steel structure system 1. When the roof tile 2 needs to be laid, multiple groups of roof tiles 2 can be stacked and placed on the ground, and after being bundled, they are hoisted on the auxiliary frame 3 by the hoisting device. The auxiliary frame 3 temporarily carries the roof tiles 2, and then drives the auxiliary frame 3 to gradually move on the steel structure system 1 along the laying direction, and the workers take out the roof tiles 2 on the auxiliary frame 3 one by one and fix and install them on the steel structure system 1. Until all the roof tiles 2 are installed, multiple groups of auxiliary frames 3 can be hoisted at one time, without the need to constantly adjust the position of the hoisting device, and the use frequency of the hoisting device can be reduced. Especially for high equipment, a lot of hoisting operations can be saved.

[0044] In the above embodiment, since the built steel structure system 1 is in a hollow state, the auxiliary frame 3 can store other related equipment such as welding machines and safety ropes when installing and constructing, in addition to carrying roof tiles 2.

[0045] In order to facilitate the workers to take and place the roof tiles 2, the embodiment further provides the following technical solutions, the limiting guardrail 32 is provided with a plurality of groups of taking and placing machines 4, the taking and placing machine 4 includes a main swing rod 41, a vice swing rod 42 and a grabbing frame 43, the main swing rod 41 is rotatably installed on the limiting guardrail 32, the vice swing rod 42 is rotatably installed on the end of the main swing rod 41, the grabbing frame 43 is installed on the end of the vice swing rod 42 away from the main swing rod 41, each main swing rod 41 is fixedly connected through a group of synchronous rods 5, each vice swing rod 42 is fixedly connected through another group of synchronous rods 5, thereby ensuring that each group of taking and placing machines 4 can work synchronously, the bottom of the grabbing frame 43 is provided with a grabbing fixator 44, the grabbing fixator 44 is used for grabbing and fixing the roof tile 2, specifically, since most of the roof tiles 2 are thin, and the surface of the roof tile 2 of the metal structure is relatively smooth, therefore, the commonly used vacuum suction disc structure can be used as the grabbing fixator 44 to grab and fix the roof tile 2, for some thicker and heavier roof tiles 2, the edges have enough space to be clamped, therefore, for such roof tiles 2, the grabbing fixator 44 can also select a jaw type structure, in addition, the grabbing fixator 44 can also use other types of grabbing structures.

[0046] It should be noted that, in actual use, referring to the drawings in the specification Figures 4 to 5 , the workers can first drive the main swing rod 41 and the grabbing frame 43 to overturn to the upper side of the auxiliary frame 3, so that the grabbing fixator 44 contacts and adsorbs the roof tile 2 on the uppermost layer of the auxiliary frame 3, then a plurality of workers at least two workers jointly lift the roof tile 2 and operate the corresponding main swing rod 41 and vice swing rod 42 to swing, so that the roof tile 2 is turned over from the inside of the auxiliary frame 3 to the outside of the auxiliary frame 3, and then the roof tile 2 is placed on the purlin 12 for installation one by one, since each main swing rod 41 and each vice swing rod 42 are relatively fixedly connected, when the roof tile 2 is lifted, the overall shape of the roof tile 2 is relatively stable, and will not be deformed greatly, thereby not damaging the roof tile 2, especially avoiding the influence caused by the different operating forces of each worker, and improving the convenience of taking and placing the roof tile 2.

[0047] Further, in order to improve the application range of the taking and placing machine 4, the embodiment further provides the following technical solutions, specifically referring to the drawings in the specification Figure 4 , the main swing rod 41 includes an outer sleeve rod 411 and a telescopic rod 412, the outer sleeve rod 411 is rotatably connected with the top of the roof tile 2, the telescopic rod 412 is slidably arranged in the outer sleeve rod 411, the vice swing rod 42 is rotatably installed on the telescopic rod 412, thereby the length of the main swing rod 41 can be adjusted, so as to better adjust the position of the grabbing frame 43 for grabbing.

[0048] Further, in the above embodiment, the grabbing frame 43 can be directly fixedly connected with the auxiliary swing rod 42, but in order to improve the operation performance of the taking and placing machine 4, a rotary connection mode can also be used, that is, the grabbing frame 43 is rotatably installed on the auxiliary swing rod 42, and each group of grabbing frames 43 are fixedly connected through another group of synchronous rods 5. Specifically, a first group of synchronous rods 5 are arranged through the limiting guardrail 32, the synchronous rods 5 are rotatably connected with the limiting guardrail 32, each group of outer sleeve rods 411 are directly fixedly connected with the synchronous rods 5, and similarly, a second group of synchronous rods 5 are arranged through each group of telescopic rods 412, the synchronous rods 5 are rotatably connected with the telescopic rods 412, each auxiliary swing rod 42 is fixedly connected with the synchronous rods 5, and a third group of synchronous rods 5 are arranged through each group of auxiliary swing rods 42, the synchronous rods 5 are rotatably connected with the auxiliary swing rods 42, and each grabbing frame 43 is fixedly installed on the synchronous rods 5.

[0049] It should be noted that the structure of the taking and placing machine 4 can be disassembled after the overall installation of the sloping roof is completed, or can be retained to facilitate the replacement of the roof tiles 2 in the later period. In order to make the operation of the workers more labor-saving, torsion springs are arranged between the outer sleeve rod 411 and the limiting guardrail 32, between the auxiliary swing rod 42 and the telescopic rod 412, and between the grabbing frame 43 and the auxiliary swing rod 42. The torsion springs are used to provide an action force opposite to the gravity of the roof tile 2 to each structure after the taking and placing machine 4 grabs the roof tile 2. A spring or the like is arranged between the telescopic rod 412 and the outer sleeve rod 411 to ensure that the main swing rod 41 has a spring force to the middle during the extension or shortening operation, thereby making the operation of the workers more labor-saving.

[0050] In addition, for the rotation and telescopic sliding of each structure, automatic control structures such as driving motors and telescopic cylinders can be directly arranged according to requirements.

[0051] Due to different building requirements, some buildings directly use roof tiles 2 with corrugated color steel tiles. The roof tiles 2 have more protruding corrugations. Referring to the drawings, the roof tiles 2 are arranged in a plurality of rows, and the roof tiles 2 in each row are arranged in a plurality of columns. Figure 4 Therefore, when stacked and placed, due to the influence of the thickness of the roof tiles 2, the corrugations between the upper and lower roof tiles 2 cannot be completely matched, and a gap can be left. Some buildings need to use relatively flat and smooth roof tiles 2. Referring to the drawings, the roof tiles 2 are arranged in a plurality of rows, and the roof tiles 2 in each row are arranged in a plurality of columns. Figure 3 and Figure 7The roof tiles 2 are relatively flat, so when actually stacked, the upper and lower roof tiles 2 are closely attached, and the air between the adjacent two layers of roof tiles 2 is squeezed out due to gravity, forming a vacuum state, so that a large suction force is easily formed between the upper and lower roof tiles 2. For thinner roof tiles 2, the edges are difficult to be grabbed by a jaw structure, and can only be adsorbed and fixed by a vacuum chuck as a grabbing fixture 44. Therefore, when actually operated, workers are prone to have difficulty in grabbing and lifting the roof tiles 2, or to lift two or three layers of roof tiles 2 at a time, which affects the installation efficiency. To this end, the embodiment further provides the following scheme. Specifically, a side lifting assembly is arranged on the limiting guardrail 32, and the side lifting assembly comprises a side lifting frame 6 which is slidingly installed on the limiting guardrail 32 and is provided with a plurality of sharp corner plug blocks 61 on one side corresponding to the inner side of the auxiliary frame 3. An active cavity 62 is formed in the side lifting frame 6, and the sharp corner plug blocks 61 are slidingly arranged in the active cavity 62. A resilient member 63 is arranged between the sharp corner plug blocks 61 and the active cavity 62, and is used to provide an outward movement elastic force for the sharp corner plug blocks 61. The side lifting assembly further comprises a lifting driving assembly 7 which is used to drive the side lifting frame 6 to move up and down.

[0052] Further, referring to the drawings in the specification Figure 10 The bottom of the sharp corner plug block 61 is provided with a beveled portion 611, and the top of the sharp corner plug block 61 is provided with a flat portion. One end of the sharp corner plug block 61 is formed into a sharp corner portion 612 corresponding to the roof tile 2.

[0053] In actual use, when the upper roof tile 2 needs to be taken out, the side lifting frame 6 is first driven to move up, so that the sharp corner plug blocks 61 move up around the roof tile 2. Under the action of the elastic force of the resilient member 63, the sharp corner plug blocks 61 are inserted into the gap between the adjacent two layers of roof tiles 2. However, for the bottom layer of roof tiles 2, the top roof tile 2 is relatively large and has a large gravity, so the sharp corner plug blocks 61 will not be inserted too deep, nor will the edges of the roof tiles 2 be lifted. However, when the side lifting frame 6 gradually moves to the upper roof tile 2, there is no other pressure above the upper roof tile 2, so the sharp corner portion 612 of the sharp corner plug block 61 can be inserted into the gap between the upper and lower roof tiles 2 relatively deeply. Under the condition that the side lifting frame 6 continues to move up, the edges of the roof tiles 2 are bent and lifted upward, so that the gap between the edges of the upper and lower roof tiles 2 is increased. Therefore, external air can gradually enter between the upper and lower roof tiles 2 through the gap, eliminating the “vacuum” state mentioned above, and making it easier to lift the upper roof tile 2. When the upper layer of roof tiles 2 is taken away, the side lifting frame 6 can be temporarily driven to move down by a distance. At this time, under the action of the beveled portion 611, the sharp corner plug blocks 61 will retract, without affecting the downward movement of the side lifting frame 6. When the next roof tile 2 is grabbed, the side lifting frame 6 is driven to move up again.

[0054] It should be noted that in the above embodiment, the lifting driving assembly 7 can adopt an automatic control structure, such as a hydraulic cylinder, but considering the weight reduction of the auxiliary frame 3 and the unsuitable setting of more equipment on the steel structure system 1 in the high working area, the lifting driving assembly 7 can also adopt a manual equipment, for example, referring to the drawings Figure 9 The lifting driving assembly 7 comprises a driving cylinder 71 and a driven cylinder 72, both of which are fixedly installed on the auxiliary frame 3, the driving cylinder 71 is slidably installed with a driving piston rod 73, the top end of the driving piston rod 73 extends to the outside of the driving cylinder 71 as an input end, the driven cylinder 72 is slidably installed with a driven piston rod 74, the top end of the driven piston rod 74 is fixedly connected with the edge lifting frame 6, the driven cylinder 72 and the bottom of the driving piston rod 73 are in communication with each other, and the driven cylinder 72 and the driving piston rod 73 are provided with a liquid medium.

[0055] In order to facilitate operation, the top end of the driving piston rod 73 can be fixedly installed with a pedal 76, in actual use, stepping on the pedal 76 makes the driving piston rod 73 press downward, that is, the liquid pressure in the driven cylinder 72 increases, and then the driven piston rod 74 rises, realizing the upward driving of the edge lifting frame 6, while after use, the pressure on the pedal 76 is removed, and the edge lifting frame 6 will slowly descend under the action of its own weight.

[0056] Further, in order to improve the separation effect of the edge of the top layer roof tile 2, the embodiment further provides the following technical scheme, specifically, referring to the drawings Figure 9 and Figure 10The driven piston rod 74 is a hollow structure, and the top end of the driven piston rod 74 is fixedly connected with a communication pipe 75, the communication pipe 75 is communicated with the movable cavity 62, and the movable cavities 62 in the edge lifting frame 6 are arranged in communication with each other, the inside of the sharp corner plug-in block 61 is provided with a liquid injection gap 613, the liquid injection gap 613 is communicated with the movable cavity 62, and the liquid injection gap 613 extends to the sharp corner part 612, and the liquid medium in the driving cylinder 71 and the driven cylinder 72 is lubricating oil, so that when the driving piston rod 73 is pressed down, a part of the lubricating oil can be sprayed from the liquid injection gap 613 under the extrusion action, and sprayed into the gap and the edge of the upper and lower roof tiles 2, forming lubrication, avoiding friction damage between the sharp corner plug-in block 61 and the roof tiles 2, and secondly, since the liquid injection gap 613 is a slit structure, the spraying amount is limited, so the driven piston rod 74 can still rise, wherein since the edge of the roof tile 2 between the upper layer regions is lifted and bent, the lubricating oil enters the gap during the lifting process, forming a barrier, so for the second layer and the third layer of the roof tile 2 (from top to bottom), since the gap edge is filled with lubricating oil in advance, the gap height at the edge of the roof tile 2 is relatively larger than the height at the center, so under the filling of the lubricating oil, part of the air enters at the edge of the gap, and it is easier to lift the edge of the roof tile 2 next time, and since there is lubricating oil, when the upper and lower roof tiles 2 are still difficult to separate, the worker can push the roof tile 2 to move relatively to improve the probability of disappearance of the "vacuum" (the vacuum pressure is in the upward and downward directions, and does not affect the planar motion of the roof tile 2), and the edge of the roof tile 2 is also protected.

[0057] It should be noted that since the edge lifting frame 6 is lifted each time, a little lubricating oil in the driven cylinder 72 is sprayed out, so when the pedal 76 is pressed again, the rising height of the driven piston rod 74 will be reduced due to the reduction of the lubricating oil, which is just suitable for the thickness reduction of the roof tile 2 on the auxiliary frame 3 after the roof tile 2 is taken out each time, and when the lubricating oil is reduced too much, the lubricating oil can be added to the driving cylinder 71.

[0058] Referring to the drawings in the specification Figure 11 The application also provides a mounting method of a steel structure metal tile pitched roof, comprising the following steps:

[0059] Step one, a steel skeleton 11 is built on the top of the building, and purline 12 is installed on the steel skeleton 11 to form a steel structure system 1;

[0060] Step two, the auxiliary frame 3 is hoisted to the steel structure system 1 and assembled, and the walking mechanism 31 is matched with the corresponding purline 12;

[0061] Step three, the taking and placing machine 4 and the synchronous rod 5 are hoisted to the auxiliary frame 3 and assembled;

[0062] Step four, stack and bundle the multiple groups of roof tiles 2 on the ground, and hoist them to the auxiliary frame 3 by hoisting equipment;

[0063] Step five, workers cooperate with the taking and placing machine 4 to take the roof tiles 2 from the auxiliary frame 3 and place them at the area corresponding to the purline 12 for fixed installation, and drive the auxiliary frame 3 to move one step backward after each roof tile 2 is installed;

[0064] Step six, after all the roof tiles 2 are installed, the taking and placing machine 4 is removed and hoisted to the ground, the auxiliary frame 3 is driven to run to the placement area 13, and the guide rail structure placed above the roof tiles 2 is installed on the steel structure system 1 to facilitate the re-moving and maintenance of the auxiliary frame 3 later.

[0065] The above-described embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application.
