Description

Technical Field

[0001] This utility model relates to the field of tent technology, specifically to a tent roof construction structure. Background Technology

[0002] Tents are simple in construction and easy to set up temporary spaces. They are mainly used for various temporary activities such as industrial warehousing, logistics distribution, business gatherings, celebrations, business promotions, and disaster relief.

[0003] In the construction of a tent, the roof is particularly important. The roof is typically constructed by building a frame with profiles, then covering it with canvas. The common method for tightening and securing the canvas is manual tensioning, followed by fixing the canvas to the frame with wire or bolts. However, this structure relies on manual tensioning, leading to unpredictable tensioning results and relatively scattered fixing points, making the canvas prone to loosening under stress during use. Patent CN202020685260.8 discloses an inflatable tension tent where two inflatable upper airbags are located on either side of the bottom of the tent fabric, arranged opposite each other. The distance between the two airbags decreases during inflation, causing the naturally drooping tent fabric to inflate and tighten. However, while tents offer advantages such as convenience, quick assembly and disassembly, and low cost, the airbags not only take up space but also leak air, requiring the constant carrying of inflation equipment. Therefore, the above design still has shortcomings.

[0004] Additionally, patent 202010320027.4, entitled "Adjustable Tensioning Purlin System for Tent Roofs," employs a four-way tensioning mechanism. Laterally, square tubes and hydraulic jacks open the gap between the roof beams, thus tensioning the roof membrane laterally. A longitudinal fastening system uses screws to press down on the membrane fastening rods, thereby tensioning the roof membrane longitudinally. As can be seen from the accompanying drawings and description, its structure is relatively complex, and the adjustment via square tubes and hydraulic jacks is somewhat inconvenient. Summary of the Invention

[0005] To overcome the above-mentioned defects, this utility model provides a tent roof construction structure that is easy and quick to disassemble and has adjustable roof membrane tension.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a roof construction structure for a tent includes left and right tensioning profiles located on both sides of the roof, which are fixedly connected by a plurality of roof purlins; a roof membrane is provided, which covers the outer layer of the roof purlins; at least one tensioning mechanism is provided for adjusting the tension of the roof membrane, and the roof membrane on the side equipped with the tensioning mechanism is fixedly installed on the tensioning profile on the same side after being tensioned and adjusted by the tensioning mechanism to form the roof.

[0007] In a preferred embodiment of this utility model: the roof membrane material has a roller on each side, and at least one of the left and right tensioning profiles has a tensioning groove on its upper end face. The tensioning mechanism is installed corresponding to the tensioning groove. The tensioning mechanism includes a cover plate corresponding to the tensioning groove and several bolts. The rear end of the bolt is connected to the bottom of the tensioning groove, and the front end of the bolt passes upward through the cover plate and is connected to the bolt nut. The roller of the roof membrane material is limited in the tensioning groove by the cover plate, and the cover plate is moved along the bolt within the groove depth range by adjusting the nut, thereby realizing the adjustment and fixation of the roof membrane material tension.

[0008] As a second preferred embodiment of this utility model: the roof membrane material has a roller on each side, and at least one of the left and right tensioning profiles has a tensioning groove on its upper end face. The tensioning mechanism is installed corresponding to the tensioning groove. The tensioning mechanism includes a cover plate corresponding to the tensioning groove and several bolts. The front end of the bolt thread passes through the cover plate and the bottom of the tensioning groove in sequence and is connected to the bolt nut. The roller of the roof membrane material is limited in the tensioning groove by the cover plate, and the cover plate is moved along the thread within the groove depth range by adjusting the bolt, thereby realizing the adjustment and fixation of the roof membrane material tension.

[0009] As a third preferred embodiment of this utility model: the roof membrane material has a roller on each side, and at least one of the left and right tensioning profiles has a tensioning groove on its upper end face; the tensioning mechanism includes a cover plate corresponding to the tensioning groove and several adjusting rods, the front end of the adjusting rod has several adjusting holes along its length, and the adjusting holes are equipped with pins; the rear end of the adjusting rod is connected to the bottom of the tensioning groove, and the front end of the adjusting rod passes upward through the cover plate; the roller of the roof membrane material is limited in the tensioning groove by the cover plate, and the position of the cover plate on the adjusting rod is adjusted by the cooperation of the adjusting holes and the pins, thereby pressing the roller to realize the adjustment and fixation of the tension of the roof membrane material.

[0010] As a further improvement of this utility model: the bottom surface of the tensioning groove is provided with a closing groove, and the rear end of the screw or the rear end of the adjusting rod is embedded in the closing groove to achieve a limiting connection between the two.

[0011] This connection structure is more convenient, and the screws or adjusting rods can be evenly arranged in the converging groove according to the number of screws or adjusting rods, thereby achieving the adjustment of a fixed position.

[0012] As a further improvement of this utility model, an elastic element is fitted on the screw or adjusting rod between the cover plate and the bottom surface of the tension groove, making disassembly and assembly more convenient.

[0013] As a further improvement of this utility model: the part of the inner side of the cover plate that is in contact with the scroll is formed into an arc surface structure, thereby achieving surface-to-surface contact between the two and preventing the scroll from sliding.

[0014] To ensure smoother adjustment, chamfers are provided on both sides of the tensioning groove shown.

[0015] As a further improvement of this utility model: the four corners of the left and right tensioning profiles are respectively provided with "C"-shaped grooves that cooperate with the roller in the extension direction. When in use, the roller can be inserted into the "C"-shaped groove to realize the limiting connection between the two, thereby ensuring the reliability and continuity of the connection between the roof membrane material and the tensioning profile in the length direction.

[0016] According to the above technical solution, this utility model has the following effects:

[0017] 1. This utility model is equipped with a tensioning mechanism, which can adjust the tension of the roof membrane material as a whole during installation, thereby ensuring that the roof membrane material is in a taut state after installation and avoiding phenomena such as water accumulation under the roof of the tent.

[0018] 2. The tensioning mechanism of this utility model has a simple structure and is easy to operate. The up and down movement of the cover plate can be controlled by rotating the bolts, thereby achieving the purpose of adjusting the tension.

[0019] 3. The tensioning mechanism and the adjustment of the cover plate of this utility model are all within the tensioning groove of the tensioning profile, and the overall structure is stable and reliable.

[0020] 4. This utility model uses bolts to pass through the cover plate, and the movement of the cover plate can be directly controlled. The deformation rate of the adjustment structure is small, the structure is more stable, and the tension adjustment efficiency is higher.

[0021] 5. This utility model allows for convenient and quick adjustment of the roller by passing a bolt through the cover plate, which can be done simultaneously on one or both sides of the bolt as needed.

[0022] 6. This utility model can achieve seamless splicing of multiple tents. Since the bolts in the same tensioning groove can be tensioned and connected on both sides at the same time, the splicing and adjustment of the roof membrane materials on both sides can be achieved through the same tensioning mechanism.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0033] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0035] like Figure 1 As shown, the tent in this embodiment includes a tent roof and four supporting legs 1.

[0036] like Figure 2 As shown, the roof of the tent in this embodiment includes left and right tensioning profiles 2 located on both sides of the roof. The left and right tensioning profiles are fixedly connected by a number of roof purlins 4, thus forming the basic frame of the roof. Of course, the roof purlins 4 can be directly fixed to the tensioning profiles or fixedly connected by adapters. These fixing methods are known technologies. A roof membrane 3 is provided, which covers the outer layer of the frame and is fixedly connected to the surrounding frame.

[0037] like Figure 3 and Figure 5 As shown: Rollers 31 are fixed to the left and right sides of the roof membrane material 3 respectively; the left and right tensioning profiles have the same structure, and a tensioning groove 21 is provided on the upper surface of the tensioning profile 2; a narrowing groove 23 is provided at the bottom of the tensioning groove along its length, which can be understood as a groove that narrows at the opening. For example... Figure 3 As shown: This embodiment is equipped with two sets of tensioning mechanisms. The roof membrane material 3 is fixedly installed on the left and right tensioning profiles after being adjusted by the tensioning mechanisms.

[0038] like Figure 3 and Figure 4 As shown: The tensioning mechanism includes a cover plate 5 corresponding to the tensioning groove and several bolts. In this embodiment, the bolts include a screw and a nut. The rear end of the screw is the fixed end in the conventional sense, and the front end of the screw is threaded. In this embodiment, the rear end of the screw 61 is connected to the constriction groove 23. The constriction groove 23 restricts the up-and-down movement of the screw 61, but it can move along the length direction within the constriction groove. Through the above design, multiple screws can be set in the constriction groove 23 to achieve multi-point fixation of the cover plate 5. The front end of the screw passes upward through the cover plate 5 and is connected to the nut 62 of the bolt.

[0039] like Figure 4 As shown: An elastic element is fitted on the screw between the cover plate 5 and the bottom surface of the tension groove. In this embodiment, the elastic element is a spring 63, but it can also be a torsion spring, disc spring, or other element.

[0040] During installation, the roll 31 of the roof membrane material is limited in the tensioning groove 21 by the cover plate 5, and the cover plate 5 is moved downward along the screw 61 by adjusting the nut 62, thereby pressing down and driving the roll to move downward, thus achieving the effect of tightening the roof membrane material 3.

[0041] like Figure 4 As shown: In order to make the tensioning of the roof membrane material smoother, chamfers are provided on both sides of the tensioning groove 21. Of course, it can also be a bevel, a rounded surface, etc., which are all similar modifications.

[0042] like Figure 4 As shown: the part of the inner side of the cover plate that meets the spool is formed into an arc surface structure, so that when the two come into contact, they form a surface contact, which prevents the spool from shaking and ensures the stability of the connection.

[0043] like Figure 5 As shown: "C"-shaped grooves 22 that mate with the rollers are provided at the four corners of the left and right tensioning profiles along their length. When only one tensioning mechanism is installed, the rollers on one side of the roofing membrane are inserted into the "C"-shaped grooves 22 to achieve a limiting connection between the two in the length direction, while the other end of the roofing membrane is fixedly installed on the tensioning profile after adjustment by the tensioning mechanism.

[0044] In this embodiment, multiple bolts can be set along the length to achieve multi-point tensioning and fixing, resulting in better performance. At the same time, in this utility model, by pressing the roof membrane material 3 down with the cover plate, a line or surface contact is formed, which can achieve overall tension adjustment and result in better adjustment effect. Example

[0045] like Figure 6 As shown: This embodiment is based on Embodiment 1, but with the bolt reversed, that is, the front end of the bolt shank 61 faces downwards, and passes through the cover plate 5 and the bottom of the tensioning groove in sequence to connect with the bolt nut 62. This ensures that the bolt shank is not exposed outside the cover plate and the roof, making it relatively safer.

[0046] For convenience, the above structure can embed the bolt nut 62 in the bottom of the tension groove, so that the cover plate 5 can be adjusted by simply rotating the rear end of the screw. Example

[0047] like Figure 7 As shown: This embodiment is based on embodiment 1, but replaces the bolt with a mating structure of adjusting rod 7 and pin 8. The front end of adjusting rod 7 is provided with several adjusting holes along the length direction.

[0048] The rear end of the adjusting rod is connected to the constriction groove 23, and the front end of the adjusting rod passes upward through the cover plate 5. During tension adjustment, after pressing down the cover plate 5 to achieve the tension, the pin 8 is inserted into the corresponding adjusting hole to fix the cover plate 5. For disassembly, simply remove the pin. Example

[0049] like Figure 8 As shown: This embodiment, based on Embodiment 1, achieves seamless splicing of two tent roofs. Both tent roofs are equipped with a tensioning mechanism. One end of the roof membrane material of the left tent roof is fixed in the "C" groove of the left tensioning profile, while the other end is fixed after adjustment via the left tensioning mechanism. One end of the roof membrane material of the right tent roof is fixed in the left tensioning profile, while the other end is fixed after adjustment via the right tensioning mechanism. Of course, there are many other splicing methods. Since the cover plate of the tensioning mechanism is divided into left and right sides by bolts or adjusting rods, and the rollers can be adjusted on both sides, the number of tensioning mechanisms can be one or more. Examples will not be listed here.

[0050] This utility model has a simple and reasonable structure and a wide range of applications. It can be used in various membrane structures, tents, awnings and prefabricated and mobile buildings.

[0051] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
