Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple tent used at a construction site or the like where a temporary covering is required.

[0002]

2. Description of the Related Art A simple tent is used to carry out construction work or put materials for a short period of time without being affected by rainy weather. In this kind of tent, the height of the tent is changed. It is not possible to respond to the volume of stored items and the progress of construction work.

[0003]

SUMMARY OF THE INVENTION Therefore, in the present invention, in a tent support structure used at a construction site or the like where a temporary covering is required, the support structure is simplified and the height of the tent sheet tension portion is increased. The challenge is to be able to change.

[0004]

In order to solve the above-mentioned problems, the supporting structure for a simple tent according to claim 1 is one in which the upright columns at the four corners are formed so as to form a square, and both ends are arranged in parallel with each other. A beam member that is vertically engaged with a column, a ridge member that is bridged between the beam members, a tent sheet that is stretched above the ridge member and fixed at both ends to the beam member, and a beam member is moved up and down. And a driving means.

The supporting structure for a simple tent according to a second aspect of the present invention is the supporting structure for a simple tent according to the first aspect, in which the beam member and the ridge member are extendable.

The support structure for a simple tent according to claim 3 is the support structure for a simple tent according to claim 1 or 2, wherein two tent sheets fixed to a beam member are partially overlapped. It is configured to be stretched.

[0007]

The pair of left and right beam members are engaged with the upright columns such that both ends thereof can move up and down. Since the columns are upright at the four corners so as to form a square, the beam members are in a parallel state.

Since the ridge member is horizontally stretched between the beam members arranged in parallel, no dent is formed in the central portion of the tent sheet stretched on the ridge member. Since the ends of the tent sheet are fixed to the beam member in a parallel state, and the beam member is moved up and down by the driving means, it is possible to select the height and support the tent while the tent sheet is stretched.

In the structure for supporting a simple tent as described above, if the beam member and the ridge member are configured to be expandable and contractible,
The tent can be stretched according to the size of the installation portion of the tent (claim 2).

If two tent sheets fixed to the beam member are partially overlapped and stretched, the tent sheet is released from the overlapped portion to form an open portion in the ceiling of the tent. Yes (Claim 3).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a rear view (inside a tent sheet tension portion) in which a beam 11 is attached between a pair of columns 1 and 1, FIG.
Shows a plan view thereof, and FIG. 4 shows an essential part of an inner side view showing a supporting state of the support column. As shown in FIG. 4, the pillar 1 is made to stand upright on the ground 10, and the reinforcing stays 5 are obliquely arranged on the side to which tension is applied when the tent is stretched. There is. Further, a wire 6 is laid between the anchor fixed in the ground and the top of the column 1 in order to prevent the tent from being blown off in the event of a gust of wind.

As for the beam 11, as shown in FIG. 1, fixed beams 12 and 12 formed in a tubular shape with a truss structure are fixed to a support body 16, and an expandable beam 13 also formed with a truss structure is arranged in the central portion. The two ends of the telescopic beam 13 are movably fitted into the fixed beams 12 and 12 so that the distance between the columns 1 and 1 can be changed. Fixed beam 12
In this embodiment, the expansion beam 13 and the expansion beam 13 are fixed by bolts (not shown) using the holes 14 and 15 formed at the tops of the two as shown in FIG. Similar holes may be drilled not only on the top but also on the bottom surface and / or the side surfaces, and these holes may be used for fixing.

As shown in FIG. 1, rollers 17, 17 are vertically mounted on the outer side of a support body 16 to which a fixed beam 12 is fixed, and are raised and lowered in a concave groove 2 formed along the inner side of a column 1. The beam 1 is engaged with the beam 1 by a driving means (not shown).
1 moves up and down along the groove 2 while maintaining a horizontal state. As this drive means, a known lifting device such as a chain block or winch can be used. In addition, the reinforcing material 1 is provided between the lower end of the fixed beam 12 and the lower end of the support 16.
9 is arranged so that the free end of the fixed beam 12 can be supported.

The inside of the top of the fixed beam 12 is shown in FIGS.
As shown in, guide rails 21 and 22 for supporting the tent sheets 20 and 30 described later are fixed in two upper and lower stages. The rails 21, 21 have a C-shaped cross section, and the rails 23, 24 each having an outer diameter slightly smaller than the inner diameters of the rails 21, 22 are inserted in the rails, and both ends thereof are inserted. Facing the rails 21, 21 and 22, 22, respectively, so that the guide rails are continuous. In addition, in FIG. 1, although the downward-facing radius is formed at the ends of the rails 21 and 22, a linear rail may be adopted. As shown in FIG. 3, the rails 23 and 24 are supported by gripping pieces 25 fixed to the telescopic beam 13 with bolts 26,
It will be fixed in a stationary state. The gripping piece 25 is fixed by selecting the holes 27, 27 formed on the top surface of the telescopic beam 13.

In the beam 11 constructed as described above, the guide rails are opposed to each other and arranged in parallel, and the ends of the tent sheets 20, 30 are inserted into the guide rails 21, 22. In this embodiment, since a rail having a C-shaped cross section is used, a bulged portion is formed along the edge of the tent sheet, and the bulged portion is inserted into the rail to support the tent sheet. Needless to say, a small-diameter roller may be attached to the edge of the tent sheet so that the tent sheet travels in the groove rail, or other known support traveling mechanism can be adopted.

If the tent ceiling is not opened / closed frequently or if it is not necessary to open / close it, it is not necessary to movably support the tent sheet. Just do it. For example, a publicly known seat attachment member such as a rope may be used instead of the guide rail, and the tent seat may be fixed to the beam 11.
FIG. 2 is a diagram showing an example of a state in which a beam is supported by a column in such a case. Fixed beam 12 in this example
The basic structure such as the structure of the expandable beam 13 is the same as that of the case of FIG. 1 (detailed structure in that the beam 11 is engaged with the column 1 by using the cylindrical support 15 and the receiving metal fitting 17). Although there is a difference in the above, there is the same means for engaging the beam 11 with the column 1 so that the beam 11 can be moved up and down), and the point that the guide rail is not attached to the beam 11 is different from the case of FIG. It is fixed to the beam 11 with a rope or the like. In this example, the chain block 7 is used as the driving means for the beam 11, and the hook 8 attached to the tip of the chain is locked to the fixed beam 12 to cause the chain block 7 to move.
The beam 11 can be moved up and down by operating.

When the tent sheet is supported by the guide rails 21 to 24 (in the case of the configuration shown in FIG. 1), the supported tent sheets 20 and 30 can be moved by attaching a rope or the like (not shown) before and after the movement. Every time, pull it, etc. As described above, the guide rails are provided in the upper and lower tiers so that the tent seats 20 and 30 can be moved relative to each other. Can be opened. On the other hand, instead of movably supporting the tent sheet with the guide rails, the tent sheet is fixed to and supported by the beam 11 with a sheet attachment member such as a rope (see FIG. 2).
In the case of the configuration shown in FIG. 6), by releasing the fixing of the tent sheet at the portion where the tent sheets 20 and 30 are overlapped (see FIG. 6), an open portion can be formed in the ceiling portion.

FIG. 5 is a plan view of the tent in a stretched state when the tent sheet is movably supported by the guide rails (in the case of the configuration shown in FIG. 1). As shown in this figure, a ridge 34 is horizontally installed between the telescopic beams 13, 13. That is, fixed ridges 35, 35 made of lightweight metal pipes and the like are projected on the extensible beams 13, 13 and an extensible ridge 36 formed of a small-diameter pipe is arranged in the middle thereof, and both ends thereof are fixed ridges 35, A ridge 34 is constructed by being inserted into and retracted from the ridge 35. The ridge 34 is arranged below the guide rails 21 to 24 and is located inside the tent. The ridge 34 may be formed in a tubular shape with a truss structure similar to that of the beam 11.

On the other hand, FIG. 6 is a plan view of the tent in a stretched state when the tent sheet is fixed and supported by the beam 11 (in the case of the structure shown in FIG. 2). In this tent, two tent sheets 20 and 30 are superposed on a ridge 31 and both ends (upper and lower sides of the tent sheet in FIG. 6) of the beam 11 are tensioned with a rope or the like not shown.
Fixed to. The ridge 31 is arranged below the tent sheets 20 and 30 fixed to the beam 11, and is located inside the tent, as described above. This ridge 31 has a structure in which both ends of a movable ridge 33 are movably fitted outside the fixed ridges 32, 32, but like the ridge 34 shown in FIG. It may be configured to be inserted into the fixed buildings 35, 35 so as to be expandable and contractible.

As can be seen from the above description, according to the tent support structure of this embodiment, since the beam 11 can be moved up and down by the driving means, the tent seat is movably supported or fixed. Regardless of whether or not the tent seat is stretched, the height can be selected to support the tent. Also, the length (left and right in FIGS. 5 and 6)
Since it is possible to expand and contract in the direction and width (vertical direction in FIGS. 5 and 6), the tent sheet can be stretched in accordance with the size of the tent installation portion. Here, when the tent sheets 20 and 30 are movably supported (in the case of FIG. 5)
Since the tent sheets 20 and 30 are vertically arranged in two layers, expansion and contraction in the length direction can be accommodated as they are.
It is possible to deal with it by providing it in parallel with. On the other hand, when the tent sheet is fixed to and supported by the beam 11 (in the case of FIG. 6), the expansion and contraction in the length direction can be adjusted by the overlapping portion of the tent sheets 20 and 30, and the expansion and contraction in the width direction. Use the fasteners and peckets to beam 11 as above.
This can be dealt with by providing it in parallel with (it is also possible to adjust the position of fixing the tent sheets 20 and 30 to the beam 11).

In the above embodiment, telescopic beams and ridges are used. However, when the tent stretched area is constant, the telescopic beams and ridges are not used and integrated beams and ridges are used. You can use the ridge.

[0022]

As described above, according to the present invention,
As a result of being able to adjust the height of the tent, there is an advantage that the height can be selected according to a desired usage pattern. For example, the height of the tent can be selected according to the volume of the stored items and the progress of the construction.

The tent support structure according to the present invention is
Since a simple mechanism in which both ends of the tent sheet are fixed to the beam members is adopted, the support itself can be made light in weight, and there is also an advantage that the assembly and the removal thereof can be performed very easily.
