Problems solved by technology

However, the membrane structure is affected by normal temperature creep and temperature performance, and the large-area membrane structure is prone to stress concentration and plastic deformation at the edge of the structure under wind and snow loads, or changes in size or relaxation due to large deformation due to temperature changes. The comparison file does not change the tension according to the change of the stress in real time
In addition, due to the fact that the buildings using membrane structures are delivered and operated, the maintenance space is limited, which brings great difficulties to the later adjustment and maintenance.
[0005] Therefore, there is a need for an automatic tensioning system and method for building membrane structures to solve the problem that the membrane structure in the prior art cannot automatically tension or relax the membrane structure according to the actual situation on site.

Embodiment 1

[0046] Such as figure 1 As shown, a building membrane structure tension automatic adjustment system includes a rectangular frame 1, which is formed by four square steel pipes 11 fixed end to end in turn, a membrane structure 3, which is arranged on the rectangular frame 1, including an electric adjustment screw 4, It includes:

[0047] The second rigid link 43 is distributed on a pair of adjacent edge portions of the membrane structure 3 at intervals;

[0048] A screw 42, one end of which is rotatably connected to the second rigid link 43, and the screw 42 moves along its axial direction to push and pull the second rigid link 43;

[0049] The motor 41 is connected to the other end of the screw 42 and drives the screw 42 to rotate forward and reverse, and the motor 41 is fixed on the rectangular frame 1 .

[0050] With such a structure, one side of the membrane structure 3 and its borders are fixed to the rectangular frame 1 by several electric adjustment screws 4, and severa...

Embodiment 2

[0078] The difference between this embodiment and Embodiment 1 is that the membrane structure 3 in this embodiment is a special-shaped structure, wherein the screw 42 pushes and pulls the second rigid connecting rod 43 along its axial direction so as to tighten or loosen the membrane surface. The axial direction depends on the length direction of the first clamp 21 facing it. The stretching direction of the strain gauge 46 is the same as the axial direction of the screw 42 .

[0079] Such as figure 2 As shown, the membrane structure 3 of this embodiment is an irregular shaped structure, and there are respectively straight-sided and arc-shaped first clamps 21, wherein:

[0080] When the first clamp 21 is straight, the axial direction of the screw 42 is perpendicular to the length direction of the first clamp 21 .

[0081] When the membrane structure 3 is an arc-shaped structure, corresponding to the membrane structure 3, the first clamp 21 is an arc-shaped edge; The arc bor...

Abstract

The invention provides an automatic tension adjustment system and working method of a building membrane structure, which includes a rectangular frame, which is formed by four square steel pipes fixed end to end in sequence, and a membrane structure, which is arranged on the rectangular frame, and includes an electric adjustment screw, which includes : the second rigid connecting rod, its interval is distributed on a pair of adjacent edge parts of the membrane structure; the screw, one end of which is rotatably connected with the second rigid connecting rod, and the screw moves along its axial direction to push and pull the second rigid connecting rod Rod; motor, which is connected with the other end of the screw rod and drives the screw rod forward and reverse, and the motor is fixed on the rectangular frame. The invention has an adjustment mechanism, which can change the tension force according to the stress change of the membrane structure itself, so as to maintain the best tension state on the membrane surface.

Description

technical field [0001] The invention specifically relates to an automatic tension adjustment system for a building membrane structure, and also specifically relates to a working method of the tension automatic adjustment system for a building membrane structure. Background technique [0002] In recent years, with the emergence of new membrane materials such as ETFE, traditional structural design methods and construction techniques are no longer sufficient to deal with complex ETFE steel-cable-membrane structures, and there is an urgent need for structural design methods and The construction technology is innovated to solve the technical bottleneck in the design and construction of complex ETFE steel-cable-membrane structures. All membrane structures currently appear in the form of small-area diaphragms and simple curved surfaces or air pillows. By reducing the stress of the membrane material or maintaining the structural tension by the inflation mechanism, the stress relaxat...
