Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a membrane material tensioning structure for a frame structure and a tensioning method thereof. Background Art

[0002] In recent years, with the development of the construction industry, the use of tensioned membranes in the fields of construction, gardening and agriculture has become more and more widespread. At present, the tensioning method of the membrane used in the frame structure is generally to first connect one end of the membrane to the frame structure, and then use a winch to tension the other end of the membrane. Among them, some existing technologies use a winch and multiple traction ropes to tension the membrane in order to save costs, but this tensioning method causes the force directions of multiple points of the membrane to be different, which will cause wrinkles and affect the tensioning quality; in order to ensure the tensioning quality of the membrane, some existing technologies need to use multiple winches to tension the membrane. This tensioning method requires the use of multiple winches, which is costly, and also requires the control machine to synchronize the operation of multiple winches and keep the force direction consistent, which makes construction difficult.

[0032] A traction main rope 5, which is connected to the traction device 4;

[0033] A plurality of pulley assemblies are used to limit the force direction of the plurality of traction ropes 7 to prevent the membrane material body 3 from wrinkling. The plurality of pulley assemblies are detachably connected to the ends of the plurality of secondary beams 2 one by one. The second end of each of the traction ropes 7 is wound around the corresponding pulley assembly and connected to the traction main rope 5. When the membrane material body 3 is in a flat state, the pulley assembly is located outside the coverage of the membrane material body 3.

[0034] The pulley assembly divides each traction 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 pulling hole. The force direction of the traction rope 7 is changed by setting the pulley assembly. No matter what the force direction of the first section is, the force direction of the second section is along the corresponding secondary beam 2 and perpendicular to the main beam 1, thereby ensuring the tensioning quality of the membrane material body 3 and avoiding 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 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 rope 7.

[0044] By providing two of the first fixed pulleys 12 and the second fixed pulley 13 , the traction rope 7 can be wound around a suitable fixed pulley according to the positional relationship between the tensioning hole 8 and the traction device 4 .

[0045] By arranging the pulley assembly into a detachable structure, it is convenient to dismantle and turn around after the membrane material body 3 is tensioned, thereby improving the construction efficiency.

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

[0047] The winch is arranged to reel in the main traction rope 5 to drive the plurality of traction sub-ropes 7 to tension the membrane material body 3 .

[0048] Preferably, each of the traction ropes 7 can be detachably connected to the corresponding tensioning hole 8 , and the first end of each of the traction ropes 7 is connected to a hook 9 for hanging on 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 tensioning of the membrane body 3 is completed, the hook 9 can be directly detached from the corresponding tensioning hole 8, thereby improving construction efficiency.
