Description

TECHNICAL FIELD [0001] The present invention relates to a pipe connecting fastener for a vinyl house, and a vinyl house structure using the pipe fastening fastener.

The present invention relates to a pipe connecting fastener for a vinyl house which can be self-assembled, has a low installation cost, and can maintain firmness even in heavy snow and strong wind, and a vinyl house structure using the same.

There are a variety of pipe frame or pipe structures installed in the outdoors such as plastic houses, parking facilities, curtains, tents, advertising displays, small warehouses, simple workplaces, and sports facilities. These pipe structures are exposed to external environments such as strong winds and heavy snow.

It is desirable to be able to withstand any external environment such as heavy snow or strong winds, but this requires a high installation cost. So far, we have found an appropriate compromise between structural stiffness and installation cost.

For example, the greenhouse, an outdoor pipe structure, has been installed with small diameter pipes with a focus on cost rather than rigidity. Small-diameter pipe structures are inexpensive but have low stiffness, so they are very likely to be damaged by severe strong winds or heavy snow.

In order to solve this problem, it is possible to install a disaster type vinyl house. The disaster type vinyl house is designed by the government. It uses a pipe of a diameter larger than that of a conventional vinyl house to increase the rigidity of the structure. To prevent the plastic house from being destroyed.

The safety of greenhouse structures for heavy snow and strong winds is determined by the strength of the pipe, the joint strength, and the robustness of the foundation. Vinyl house structures with small pipe diameters, weak joints and poor foundation are inexpensive to install, but are vulnerable to heavy snow or strong winds.

However, it is possible to provide strong structures against heavy snowfall and strong wind by thickening the pipe diameter like a disaster type vinyl house, using a strong joint and strengthening the foundation by burying the line base pipe deep in the ground, There is a problem that the cost is increased more than 1.5 times.

In addition, pipe bending and complicated assembly methods are bound to rely on professional installers, which can make self-assembly difficult and thereby increase installation costs even more.

11 to 13 are perspective views illustrating a greenhouse structure according to a fourth embodiment of the present invention.

11 to 13, a vinyl house structure according to a fourth embodiment of the present invention uses a pipe connecting fastener according to the first, second, or third embodiment, , Wherein the circumferential surface of the vinyl house structure is constituted by an aggregate of the triangular shape (310), and each side of the triangular shape is composed of a non-bent pipe, that is, a non-bent pipe , And the pipe tangent to the vertex on the triangle is connected to the pipe connecting fastener 100.

The triangular shape 310 may be an equilateral triangle or an isosceles triangle.

For example, when the horizontal angle x of the pipe connecting fastener is 30 degrees or 75 degrees, the triangle may be an isosceles triangle as shown in FIG. 12 or FIG. 13, and when the horizontal angle x is 60 degrees 11, the triangular image may be an equilateral triangle.

Also, the roof area of the vinyl house structure may adopt a hexagonal honeycomb structure, which is an aggregate of the triangular shapes 310, and the eave surface may be an aggregate of the triangular shapes 310 or another aggregate of triangles 320 It can adopt a diagonal structure. Due to the above structure, the external load is uniformly dispersed and can withstand heavy snowfall and strong wind.

Then, the pipe can be self-assembled by cutting the straight pipe without the pipe bending operation and fixing it by using the pipe connecting fastener 100. The pipe connecting fastener 100 can solve the problem caused by the strength and the joining force, and a tongue wrench bolt is pre-installed in the joining groove of the pipe joining fastener so that the joining of the pipe joining fastener can be easily carried out. So that the vinyl house structure can be installed quickly and easily.

The installation process of the vinyl house structure according to the embodiment of the present invention will be described in detail. First, the string base pipe 7 to be a base is buried in the ground and assembled into a square. Thereafter, the eave S is set up along one side 7a of the quadrilateral foundation pipe 7, the roof R is made from the eave S, The vinyl house structure can be installed by assembling one by one.

In more detail, the base pipe 7 to be buried in the ground is assembled into a square by using the joint or the first joint 130. For example, after the first joint 130 is inserted and positioned in the row foundation pipe 7a under the eave surface S, the tundish wrench bolt built in the first joint 130 is tightened with an allen wrench Conclude. If the elongated base pipe 7a is too long, it may be heavy and difficult to handle, so that two short pipes can be connected in the middle using a pipe connector.

Next, the second joint 150 is fastened to the longitudinal rib base pipe 7b in the longitudinal direction. The position of the second joint 150 may be determined by the width d of the vinyl house pipe frame. For example, for a 6 m wide, the gap between the loop joints connecting the diagonal pipes may be 6 m / cos 30,, about 1.8 m. In the case where a pipe for a plastic house is provided by being cut at a factory, a joint position may be previously displayed or provided for user's convenience of assembly, or the second joint 150 may be provided in advance by fastening. The long line foundation pipe (7b) in the longitudinal direction is heavy if it is too long, so it can be cut by about 3 ~ 5m units for assembly and can be connected by pipe connection.

The string base pipe (7) is buried in the ground so that the vinyl house structure can not be pulled out by the strong wind. The first joint 130 and the second joint 150 may be a modified form of the pipe connecting fastener according to the embodiment of the present invention.

When the bottom side rectangular base pipe 7 structure is completed, the eave S is assembled to the top of the row base pipe 7a under the eave. The first joint 130 and the second joint 150 may be connected to each other by attaching a door pipe and an end diagonal pipe to each other and tightening the tongue wrench bolts. The eaves (S) assembly can be carried out while standing, but most of the assembly can be raised and laid on the ground.

After the eave S is completed, the pipe connecting fasteners 100 of the present invention are used to sequentially connect pipes one by one from the eaves S to the corresponding eaves. If a ladder or a scaffold is installed inside the pipe structure, it is possible to fit the crossbar pipe 1 to the pipe connection fastener 100 and tighten the wrench bolt alone.

When the pipe assembly of the roof R is completed, finally, the remaining eave is assembled, which may be the same as the above-mentioned assembling process of the eave (S) assembly.

The roof area of the vinyl house structure installed in the above process is formed of a hexagonal honeycomb structure that is an aggregate of the triangular shape 310 and the eave surface is a collection of the triangular shape 310 or another aggregate of the triangular shape 320 As shown in FIG.

During the assembly process, the total installation cost can be reduced by using a coarse and long pipe to reduce the number of joints and pipe connection fasteners. Also, as shown in Table 2, the pipe connecting fastener 100 is improved in strength and bonding force as compared with a joint used in a conventional vinyl house. As a result, the rigidity of the vinyl house structure of the present invention is further improved .

In addition, since the vinyl house structure using the pipe and the connecting fastener 100 can be selected in various widths and lengths, if the pipes are damaged due to heavy snowfall or strong winds, the pipes can be replaced with new ones. It is possible to regenerate it at a cost of.

Furthermore, since the diameter or the thickness of the pipe can be changed according to the portion of the entire vinyl house structure, it can effectively cope with snowfall and strong wind. The snow load takes a lot of load at the center of the frame, and the lateral wind load takes a lot of load at the eaves of the ends of the frame. Therefore, if the thick loader is reinforced by thick and thick pipe, .
