Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an air membrane tent used for temporary structures and the like.

(Prior art) This type of conventional air membrane tent uses a blower to inflate the tent membrane by filling air at a pressure slightly higher than atmospheric pressure into the tent membrane, and is attached to the hem of the tent membrane. The tent membrane was fixed to the ground by anchoring tethering cables, angle materials, etc. to screw anchors penetrated into the ground.

(Problems to be solved by the invention) In the conventional air membrane tent, construction of screw anchors requires machinery such as heavy machinery, which requires a lot of effort, time, and cost, and also causes the problem of underground objects being buried underground. If this happened, it would be impossible to install the screw anchor, and if the anchor position shifted, reinforcement would be required.

Furthermore, when removing the air membrane tent, it took a great deal of effort, time and money to pull out the screw anchor from the ground.

Furthermore, since the internal pressure of the tent membrane is adjusted by active action, failure of the blower or the like may cause the internal pressure to rise abnormally, causing the tent membrane to break or the anchor to come off.

(Means for solving the problem) The present invention was proposed in order to eliminate such problems. Air at a pressure slightly higher than atmospheric pressure is sealed inside the tent membrane, and the tent membrane is inflated. Therefore, in an air membrane tent configured to form a usable space on the installation surface, a horizontal plate-shaped weight fixed to the hem of the tent membrane is placed on the tent installation floor surface so that the internal pressure of the tent is within a certain limit. The present invention relates to an air membrane tent that is placed so as to float above the floor surface when the air temperature exceeds the air temperature.

(Function) As mentioned above, the air membrane tent according to the present invention has the following features:
A horizontal plate-shaped weight is fixed to the hem of the tent membrane, so by placing the weight on the air membrane tent installation floor, the air membrane tent can be placed on the installation surface via the weight. It is fixed. At this time, since the weight is formed in the shape of a horizontal plate, the ground contact area is large and it can sit stably on the installation floor, making it easy to install the air membrane tent on the same floor. , will be carried out reliably.

Further, the weight has a large surface area in contact with the floor, and therefore has a large frictional resistance with the surface in contact with the floor. In addition, by using a horizontal plate-shaped weight with high lateral rigidity, there is no lateral movement when the air membrane tent is subjected to a force that causes it to shift in the lateral direction due to external wind force or the like.

In addition, when excessive internal pressure acts on the tent membrane, the horizontal plate-shaped weight is lifted from the installation floor, and the air membrane inside the tent is lifted from the gap formed between the installation floor and the hem of the tent membrane. Air leaks out and damage to the tent membrane is prevented.

(Example) The present invention will be described below with reference to the illustrated embodiments.

In Fig. 1, 1 is a tent membrane, and 2 is a seal membrane. An angle material 3 is fixed to the hem of the tent membrane 1, and a horizontal plate 5 has four groups of reinforcing rods welded to the lower part of the angle material 3. A horizontal plate-shaped weight is fixed, and the horizontal plate 5 is placed on the floor surface a. Note that the reinforcing bar 4 may be placed directly on the floor surface a as shown by the dotted line.

Since the illustrated embodiment is configured as described above, when an excessive internal pressure acts on the tent membrane 1, the horizontal plate 5 and the reinforcing bar 4 are lifted up, and the gap between the tent membrane 1 and the floor surface a is lifted. A gap is formed between the tent membrane 1 and the air inside the tent membrane 1 to leak through the gap, thereby preventing the tent membrane 1 from being damaged and at the same time maintaining its shape.

In the embodiment shown in FIG. 2, an iron plate 6 or a lead plate is used as a weight instead of the horizontal plate 5 and reinforcing bar 4.

In the figure, parts equivalent to those of the above embodiment are given the same reference numerals.

(Effect of the invention) According to the invention, when installing an air membrane tent, all that is required is to place a horizontal plate-shaped weight fixed to the hem of the tent on the installation surface. It is easy to install and can be installed without any problems even if there are objects buried underground. Furthermore, the removal process is easy, and the air membrane tent can be easily relocated.
At that time, there is no risk of anchors remaining underground.

Further, since the weight is formed in the shape of a horizontal plate, the installation floor area is large, and the air membrane tent can be stably installed on the installation floor, and the installation work of the weight on the floor can be easily performed. When an air membrane tent is installed on the floor of a structure, etc., the load of the weight is transmitted over a wide area to the floor by the horizontal plate-shaped weight with a large contact area, and the floor becomes heavy. There is no risk of loss due to the weight. Furthermore, the horizontal plate-shaped weight has high lateral rigidity and, as mentioned above, has a large surface area in contact with the floor, so the frictional resistance with the floor surface is large, and the air membrane tent is subjected to the force of shifting in the lateral direction due to external wind force. There is no lateral movement when the tent is moved, and deflation of the tent due to air leakage can be prevented, and the tent can reliably maintain its shape.
