Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a membrane tensioning structure for frame structures and its tensioning method. Background Technology

[0002] In recent years, with the development of the construction industry, the use of tensile membrane structures in architecture, landscaping, and agriculture has become increasingly widespread. Currently, the general method for tensioning membranes on frame structures involves first connecting one end of the membrane to the frame structure, and then using a winch to tension the other end. Some existing technologies use a single winch and multiple traction ropes to tension the membrane to save costs. However, this method results in uneven stress directions at multiple points on the membrane, leading to wrinkles and affecting the tensioning quality. Other existing technologies require multiple winches to ensure tensioning quality. This method is more costly and requires controlling the synchronous operation of multiple winches and maintaining consistent force directions, making construction more difficult. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a membrane tensioning structure and tensioning method for frame structures. By using a pulley assembly to restrict the force direction of each traction sub-rope to be perpendicular to the main beam, the tensioning quality of the membrane body is guaranteed. Moreover, only one winch is needed for tensioning, saving construction costs.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is a membrane tensioning structure for a frame structure. The frame structure includes a main beam and multiple secondary beams arranged in parallel at intervals. Each secondary beam is vertically connected to the main beam. The membrane body covers the top of the multiple secondary beams and is connected at one end to the main beam. The tensioning structure includes:

[0005] Multiple tension holes are spaced apart along the length of the main beam and opened on the membrane body at one end relatively away from the main beam. In the flat state of the membrane body, the multiple tension holes are located directly above the multiple secondary beams in a corresponding manner.

[0006] Multiple traction ropes are used to tension the membrane material body, and the first ends of the multiple traction ropes are connected to the multiple tensioning holes one by one.

[0007] The main traction rope is connected to the traction device.

[0008] Multiple pulley assemblies are used to limit the direction of force applied by the multiple traction sub-ropes to prevent wrinkling of the membrane body. The multiple pulley assemblies are detachably connected to the ends of the multiple secondary beams one to one. The second end of each traction sub-rope is wound around the corresponding pulley assembly and connected to the traction main rope. In the flat state of the membrane body, the pulley assembly is located outside the coverage area of ​​the membrane body.

[0009] A further improvement of the present invention for membrane tensioning structures in frame structures is that a force-equalizing rod is connected between the main traction rope and the multiple traction sub-ropes. The force-equalizing rod is arranged along the length direction of the main beam. The main traction rope is located on one side of the force-equalizing rod and is perpendicularly connected to the middle of the force-equalizing rod. The multiple traction sub-ropes are located on the other side of the force-equalizing rod and are symmetrically distributed around the middle of the force-equalizing rod.

[0010] A further improvement of the present invention for membrane tensioning structures in frame structures is that the pulley assembly includes:

[0011] Sleeves used to clamp onto the ends of secondary beams;

[0012] U-shaped plate, the U-shaped plate being connected to the top of the sleeve;

[0013] Two first fixed pulleys are selectively wound around the traction rope. The two first fixed pulleys are respectively connected to the opposite inner sides of the two flanges of the U-shaped plate. A channel is formed between the wheel surfaces of the two first fixed pulleys for the second end of the traction rope to pass through. The two first fixed pulleys provide horizontal guidance for the traction rope.

[0014] A further improvement of the present invention for membrane tensioning structures in frame structures is that the height of the traction device is lower than that of the frame structure, and a second fixed pulley is connected to the inner side of the web of the U-shaped plate. The wheel surface of the second fixed pulley and the wheel surfaces of the two first fixed pulleys together form the channel, and the second fixed pulley provides vertical guidance for the traction sub-rope.

[0015] A further improvement of the present invention for membrane tensioning structures in frame structures is that the traction device is a winch, and the traction main rope is wound around the shaft of the winch.

[0016] A further improvement of the present invention for membrane tensioning structure of frame structure is that each of the traction sub-rods is detachably connected to the corresponding tensioning hole, and the first end of each traction sub-rod is connected to a hook for hooking to the corresponding tensioning hole.

[0017] A method for tensioning membrane materials in a frame structure includes the following steps:

[0018] Step 1: Provide the membrane tensioning structure for the frame structure as described above and install it in place;

[0019] Step 2: Start the traction device and control the main traction rope to drive multiple traction sub-ropes to tension the membrane body until the membrane body is laid flat and taut.

[0020] Step 3: Connect the membrane body to the multiple secondary beams and remove the membrane tensioning structure.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] By setting up the pulley assembly, it is ensured that the force applied by each traction rope to the membrane body is perpendicular to the main beam, thus avoiding wrinkles during membrane tensioning and improving construction quality. Attached Figure Description

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0028] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further explanation of the membrane tensioning structure and tensioning method for frame structures according to the present invention.

[0029] Please see Figures 1-2As shown, a membrane tensioning structure for a frame structure is provided. The frame structure includes a main beam 1 and multiple secondary beams 2 arranged in parallel at intervals. Each secondary beam 2 is vertically connected to the main beam 1. A membrane body 3 covers the top of the multiple secondary beams 2 and is connected at one end to the main beam 1. The tensioning structure includes:

[0030] Multiple tension holes 8 are spaced apart along the length of the main beam 1 and are opened on the membrane body 3 at one end relatively away from the main beam 1. In the flat state of the membrane body 3, the multiple tension holes 8 are located directly above the multiple secondary beams 2.

[0031] Multiple traction ropes 7 are used to tension the membrane body 3, and the first ends of the multiple traction ropes 7 are connected to the multiple tensioning holes 8 in a one-to-one correspondence.

[0032] The main traction rope 5 is connected to the traction device 4.

[0033] Multiple pulley assemblies are used to limit the direction of force applied by the multiple traction sub-ropes 7 to prevent wrinkles in the membrane body 3. The multiple pulley assemblies are detachably connected to the ends of the multiple secondary beams 2 in a one-to-one correspondence. The second end of each traction sub-rope 7 is wound around the corresponding pulley assembly and connected to the traction main rope 5. In the flat state of the membrane body 3, the pulley assembly is located outside the coverage area of ​​the membrane body 3.

[0034] The pulley assembly divides each traction sub-rope 7 into two sections: the first section is from the pulley assembly to the traction main rope 5, and the second section is from the pulley assembly to the connection hole. By setting the pulley assembly, the direction of force applied to the traction sub-rope 7 is changed. Regardless of the direction of force applied to the first section, the direction of force applied to the second section is along the corresponding secondary beam 2 and perpendicular to the main beam 1, which ensures the tensioning quality of the membrane body 3 and avoids wrinkles.

[0035] Preferably, a force equalizing rod 6 is connected between the main traction rope 5 and the multiple traction sub-ropes 7. The force equalizing rod 6 is arranged along the length direction of the main beam 1. The main traction rope 5 is located on one side of the force equalizing rod 6 and is vertically connected to the middle of the force equalizing rod 6. The multiple traction sub-ropes 7 are located on the other side of the force equalizing rod 6 and are symmetrically distributed around the middle of the force equalizing rod 6.

[0036] Specifically, the force-equalizing bar 6 is a steel pipe with uniformly distributed mass.

[0037] Specifically, when tensioning the membrane body 3, the position of the force equalizing rod 6 is adjusted so that the line connecting the midpoint of the force equalizing rod 6 and the midpoint of the main beam is perpendicular to the main beam.

[0038] By setting the force equalizing bar 6 and restricting the position of multiple traction sub-ropes 7, it is ensured that the force equalizing bar 6 is parallel to the main beam 1 when the membrane body 3 is under tension, and that the force on each traction sub-rope 7 is uniform, thus further improving the tensioning effect.

[0039] Preferably, the pulley assembly includes:

[0040] Sleeve 10 is used to clamp the end of the secondary beam 2;

[0041] U-shaped plate 11, which is connected to the top of the sleeve 10;

[0042] Two first fixed pulleys 12 are selectively wound around the traction rope 7. The two first fixed pulleys 12 are respectively connected to the opposite inner sides of the two flanges of the U-shaped plate 11. A channel is formed between the wheel surfaces of the two first fixed pulleys 12 for the second end of the traction rope 7 to pass through. The two first fixed pulleys 12 provide horizontal guidance for the traction rope 7.

[0043] Preferably, the height of the traction device 4 is lower than that of the frame structure, and a second fixed pulley 13 is connected to the inner side of the web of the U-shaped plate 11. The wheel surface of the second fixed pulley 13 and the wheel surfaces of the two first fixed pulleys 12 together form the channel, and the second fixed pulley 13 provides vertical guidance for the traction sub-rope 7.

[0044] By setting two fixed pulleys 12 and 13, the traction rope 7 can select a suitable fixed pulley for winding according to the positional relationship between the tensioning hole 8 and the traction device 4.

[0045] By making the pulley assembly a detachable structure, it is easy to dismantle and reuse the membrane material after the third tensioning is completed, thus improving construction efficiency.

[0046] Preferably, the traction device 4 is a winch, and the traction main rope 5 is wound around the shaft of the winch.

[0047] The winch is set up to wind up the main traction rope 5, thereby driving multiple sub-traction ropes 7 to tension the membrane body 3.

[0048] Preferably, each of the traction sub-rods 7 is detachably connected to the corresponding tensioning hole 8, and the first end of each of the traction sub-rods 7 is connected to a hook 9 for attaching to the corresponding tensioning hole 8.

[0049] By connecting the hook 9 to the first end of each traction rope 7, installation and removal are facilitated. After the membrane body 3 is tensioned, the hook 9 can be directly detached from the corresponding tensioning hole 8, thus improving construction efficiency.

[0050] A method for tensioning membrane materials in a frame structure includes the following steps:

[0051] Step 1: Provide the membrane tensioning structure for the frame structure as described above and install it in place;

[0052] Step 2: Start the traction device 4 and control the main traction rope 5 to drive multiple traction sub-ropes 7 to tension the membrane body 3 until the membrane body 3 is laid flat and taut.

[0053] Step 3: Connect the membrane body 3 to the multiple secondary beams 2 and remove the membrane tensioning structure.

[0054] Specifically, when performing step 3 above, the membrane body 3 is fixed to multiple secondary beams 2 using bolts. Both the membrane body 3 and the secondary beams 2 have connection holes for the bolts to pass through.
