Description

Extender for extending length of support

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a support for a building, and more particularly, to an extender for extending a support length, which can be easily connected to a support pipe through a simple screw fastening operation.

Generally, a supporting device for supporting the lower part of concrete or building site is used for pouring and curing concrete. A representative example of the supporting device is a pipe-type building support.

This construction support is used in a plurality of construction sites, so that a function of absorbing and supporting a compressive load of an excessive roof structure, which is locally applied during construction, with a uniform distribution load is provided.

That is, in order to construct a slab for partitioning upper and lower layers when a building is constructed, a slab formwork is installed at a lower portion of a slab to be installed. In the construction process, a temporary beam such as a joist line and a yoke Beams support the die, and the lower of the hypothetical beams support the pipe supports.

In order to adjust the height of the support beams, the supports are generally assembled in a height-adjustable structure.

As a representative example of such a construction support, there is a construction support provided with a hinge-type receiving plate disclosed in Korean Registered Utility Model No. 20-389388, which is provided with a support plate on one side, An outer pipe having a diameter larger than that of the inner pipe and having a support plate formed on one side and an adjustment screw having a long hole formed on both sides of the inner pipe; A fixing pin for fixing the outer pipe, and a height adjusting nut coupled to the adjusting screw to support both ends of the fixing pin.

Therefore, when the height adjusting nut is rotated in a state where one end of the inner pipe is inserted into one end of the outer pipe and the fixing pin is passed through the long hole and the pin hole and placed on the height adjusting nut, So that the inner / outer pipe moves relative to the length of the elongated hole of the adjustment screw to adjust the overall height of the support.

However, since the length of the elongated hole formed in the adjustment screw portion of the outer pipe is limited when the height of the conventional construction support having the above structure is adjusted, even if the height of the support is adjusted through the height adjusting nut, .

Therefore, when the height of the support is to be extended much longer than the length of the long hole, the inner pipe or the outer pipe must be used as a long length or the length of the long hole must be greatly increased. However, There has been a problem that a great deal of time and effort is required for the operator to attach the support since the weight is increased. Also, if the length of the long hole is excessively increased, the structural rigidity of the outer pipe is significantly lowered, There was a problem that could cause.

Registration Utility Model No. 20-389388 (20015.07.01)

SUMMARY OF THE INVENTION It is an object of the present invention to provide an extender for extending a length having an end shape similar to an end of an outer pipe coupled with an inner pipe in a support, Which can be easily coupled to the outer pipe portion of the support by screw fastening so that the length of the support can be easily extended to a required length.

FIG. 1 is a perspective view showing a support with a support length extension extender according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of FIG.

Referring to FIGS. 1 and 2, a support 100 according to an embodiment of the present invention includes an inner pipe 120, an outer pipe 110, and an extender 140.

The inner pipe 120 is formed with a plurality of pinholes 122 at regular intervals along the longitudinal direction on both outer surfaces so that the fixing pins 170 can be inserted.

The outer pipe 110 is formed to have an inner diameter larger than the outer diameter of the inner pipe 120 so that the inner pipe 120 can be drawn in. At the lower end of the outer pipe 110, (112) is formed. On both sides of the adjustment screw part 112, a slot 114 into which the fixing pin 170 can be inserted is formed.

A connecting portion 150 for connecting a horizontal connecting member 180, which will be described later, is coupled to the outer surface of the outer pipe 110.

At this time, the connection portions 150 may be provided in at least one number and may be coupled with a predetermined spacing in the vertical direction.

The extender 140 is a structure having a predetermined unit length so as to extend the length of the support 100. The extender 140 may include one or more numbers between the upper end of the inner pipe 120 and the lower end of the outer pipe 110 Thereby enabling the entire length of the support 100 to be extended.

FIG. 3 is an enlarged perspective view showing the structure of the extender 140 according to the present invention in detail, and FIG. 4 is an exploded perspective view of FIG.

3 and 4, the extender 140 according to the present invention includes a first coupling portion 141 coupled to the inner pipe 120, a second coupling portion 144 coupled to the outer pipe 110, And an extension part 146 connected between the first and second coupling parts 141 and 144.

The first coupling portion 141 positioned at the lower end of the extender 140 is formed to have the same shape as the shape of the lower end of the outer pipe 110 for compatibility with the inner pipe 120.

That is, after the extender 140 is connected to the lower end of the outer pipe 110, the shape of the lower end of the extender 140 connected to the inner pipe 120 may be the same as the shape of the lower end of the outer pipe 110 The shape of the lower end of the extender 140 is the same as the shape of the lower end of the outer pipe 110.

The outer diameter of the first coupling portion 141 and the extension portion 146 of the extender 140 is the same as the outer diameter of the outer pipe 110. [ The outer diameter surfaces of the extender 140 and the outer pipe 110 are positioned on the same line except for the portion of the second coupling portion 144 in a state where the extender 140 is coupled to the outer pipe 110.

An adjustment screw 142 for fastening the height adjusting nut 160 is formed on the first coupling portion 141 so as to correspond to the shape of the end of the outer pipe 110 and fixed to both sides of the adjustment screw 142 An elongated hole 143 into which the pin 170 can be inserted is formed.

When the extender 140 and the inner pipe 120 are connected to each other through the first coupling portion 141, the adjusting screw 142 formed on the first coupling portion 141 is provided with a height adjusting nut 160 The upper end of the inner pipe 120 is drawn into the first engaging portion 141 and then the long hole 143 formed in the first engaging portion 141 and the pin hole 122 of the inner pipe 120 And the both ends of the inserted fixing pin 170 are supported on the upper ends of the height adjusting nuts 160 so that the extender 140 can be supported without being moved downward in the downward direction have.

The second engaging portion 144 disposed at the upper end of the extender 140 has an outer diameter larger than that of the first engaging portion 141 and is protruded in the radial direction.

A screw thread 147 is formed on a part of the inner surface of the second coupling part 144 so as to be coupled with the lower end of the outer pipe 110 having the adjustment screw part 112 through a screw connection.

A thread 147 is formed on the inner surface of the second coupling portion 144 and a thread 147 is formed on the inner surface of the outer pipe 110 so as to be coupled with the adjustment screw portion 112 of the outer pipe 110, And an extension guide portion 144b extending from the upper side of the nut tube portion 144a.

The nut tube portion 144a is disposed on the lower side of the second coupling portion 144 and the upper end of the nut tube portion 144a is welded to the lower end of the extension guide portion 144b. The lower end of the nut tube portion 144a is joined to the upper end of the extension portion 146 through welding.

At this time, the nut tube portion 144a is formed to have a thickness that is thicker than the tube of the extension guide portion 144b in order to facilitate the formation of the screw thread 147 while having a suitable rigidity required for coupling with the outer pipe 110 .

In addition, the tube of the extension guide 144b has a thickness that is the same as the tube of the outer pipe 110.

By forming the tube of the extension guide portion 144b to have the same thickness as the tube of the outer pipe 110, it is possible to reduce the production cost by reducing the amount of metal material required for manufacturing the extender 140, The increase in the weight of the support member 140 is not so large, and workability at the time of extending the length of the support 100 can be prevented from being lowered.

The extension guide portion 144b is formed to have a smaller tube thickness than the nut tube portion 144a and to extend from the upper end of the nut tube portion 144a to a predetermined height so as to surround the lower end of the outer pipe 110. [

The outer diameter surface of the extension guide portion 144b is disposed on the same plane as the outer diameter surface of the nut tube portion 144a and the inner diameter surface of the extension guide portion 144b is connected to the adjustment screw portion of the outer pipe 110. [ (Not shown).

The nut 147 is formed at the lower end of the second coupling part 144 so as to be fastened to the adjustment screw part 112 of the outer pipe 110 and the nut tube part 144a The extension guide portion 144b having a thinner tube thickness is formed on the upper portion of the outer pipe 110 so as to surround the outer surface of the adjustment screw portion 112 of the outer pipe 110 so that the total weight of the extender 140 and the material cost are not greatly increased The coupling force between the extender 140 and the outer pipe 110 can be firmly and stably maintained.

Since the interconnected inner circumferential surface passages form a generally smooth passage surface having no protruding structure when the extender 140 and the outer pipe 110 are coupled to each other, the outer pipe 110, including the extender 140, So that the inner pipe 120 can smoothly enter and exit into the interior.

A pinhole 145 into which the fixing pin 170 can be inserted is formed on the outer surface of the extension guide portion 144b. Accordingly, when the extender 140 is fixed to the outer pipe 110 and then the fixing pin 170 is inserted and fixed through the elongated hole 114 of the pin hole 145 and the outer pipe 110, The outer pipe 110 can be prevented from being separated from the outer pipe 110 because the rotation of the outer pipe 110 is suppressed. In addition, since the joint position between the extender 140 and the outer pipe 110 can be precisely fixed, it is possible to quickly and easily connect the neighboring supporters 100 through the horizontal connecting member 180 .

The extender 140 according to the present invention having the above-described structure sequentially connects one or more of the outer pipes 110 to the inner pipe 120 when the support 100 needs to be extended, It is possible to extend the length of the body 100 to a required length.

In this case, since the extender 140 is manufactured in a predetermined length and weight unit, which is easy to work, and can be easily connected to each other by a screw fastening method, the worker has a relatively large force So that the work can be performed easily.

For reference, the reference numeral 162 denotes a handle provided on the height adjusting nut 160.

5 is a cross-sectional view showing a state in which the length of the support 100 is extended by using one extender 140 manufactured in a unit length. 6 and Fig. 7 are enlarged sectional views of the "A" portion and the "B" portion of Fig. 5, respectively.

Hereinafter, a method of extending the length of the support 100 using the extender 140 of the present invention will be described with reference to FIGS. 5 to 7. FIG.

The extension of the support 100 using the extender 140 of the present invention is performed by first tightening the portion of the second engaging portion 144 of the extender 140 at the lower end of the outer pipe 110 in a screw- .

That is, the upper end second coupling portion 144 of the extender 140 is inserted into the lower adjustment screw portion 112 of the outer pipe 110, and the lower end nut pipe 144a of the second coupling portion 144 The inner thread portion 147 and the adjusting screw portion 112 at the lower end of the outer pipe 110 are mutually engaged and fastened to each other.

Since the extension of the length of the extension portion 146 and the length of the first coupling portion 141 of the extender 140 is made with respect to the outer pipe 110, So that the shape of the lower end of the outer pipe for connection with the inner pipe 120 can be maintained as it is.

6, after the fixing operation of the extender 140 is completed at the lower end of the outer pipe 110, a portion of the adjusting screw 142 formed in the first engaging portion 141 of the extender 140 is provided with a height adjusting nut The upper end of the inner pipe 120 is inserted into the first coupling portion 141 and then the fixing pin 170 is inserted into the slot 143 formed in the adjusting screw portion 142, And the pin hole 122 of the inner pipe 120 so that both ends of the fixing pin 170 are supported on the upper surface of the height adjusting nut 160 to complete the primary height extending operation of the support 100 .

When the height of the support 100 is completed through the extender 140 as described above, the lower end and the upper end of the support 100 are then completely abutted against the floor E and the slab mold F A secondary fine height adjustment operation is required.

That is, when the height adjusting nut 160 fastened to the adjusting screw portion 142 of the extender 140 is rotated, the height adjusting nut 160 is lifted or lowered by the adjusting screw portion 142 of the extender 140 It is possible to finely adjust the height of the support 100 through the height adjustment using the height adjusting nut 160 so that the upper and lower ends of the support 100 can be fixed to the slab form F So that it can be firmly supported on the bottom surface and the top surface of the floor (E).

After the at least one extender 140 manufactured to have a predetermined unit length is coupled to the end of the outer pipe 110 of the support 100 in a screw tightening manner and the end of the coupled extender 140 is fixed to the fixing pin 170 The height of the support 100 can be quickly and easily extended to a desired height without applying a relatively large force.

8 shows a state in which the support 100 having the extended length is connected between the floor E and the mold F and the neighboring supports 100 are interconnected through the horizontal connecting member 180 And FIG. 9 is a plan view of FIG. 8 as viewed from above.

After the height of the support 100 has been increased through the extender 140 as described above, a fixing pin 170 is fixed to the extender 140 and the outer pipe 110 to prevent rotation between the extender 140 and the outer pipe 110. [ If the structure is not used, a situation may occur in which the screw fastening between the extender 140 and the outer pipe 110 is loosened or loosened.

In this case, since the supporting force of the support 100 is lost, the load of the slab can not be properly supported, so that the safety may be exposed. Therefore, there is a need for a structure that can securely hold the extender 140 without being rotated by the magnetic force in the state where the extender 140 is fastened to the outer pipe 110.

To this end, as shown in FIGS. 8 and 9, the outer pipes 110 of the adjacent supports 100 or the extensions 140 are connected to each other by the horizontal connecting member 180 .

That is, the connecting portion 150 is fixedly connected to the outer surface of at least one of the extension portion 146 of the extender 140 and the outer pipe 110, and the connecting portion 150 of the adjacent extender 140 The extender 140 and the outer pipe 110 may be fixed to the outer pipe 110 by fastening both ends of the outer pipe 110 in the circumferential direction or by fastening both ends of the horizontal pipe 180 to the connection part 150 of the adjacent outer pipe 110, So that it can be forcibly fixed so as not to be rotated.

After the installation work of the support 100 using the extender 140 is completed, the horizontal connecting member 180 is connected to the outer pipe 110 to restrict the circumferential rotation of the extender 140 and the outer pipe 110, It is possible to prevent the threaded portion of the pipe 110 from loosening or loosening.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Will be possible.
