Description

[0001] The present invention relates to a pipe support having enhanced compressive strength,

The present invention relates to a device for reinforcing the compressive strength of a pipe support used in a construction site.

In the construction process of the concrete, the formwork should be constructed in the concrete pouring and curing process.

In particular, when a slab is to be installed, a plurality of pipe supports are installed to support the load of the slab formwork and the concrete placed thereon. The support structure includes a 'single type' in which the supporting members are integrally formed, And the 'combined' type.

1 shows an example of a conventional combined pipe support.

The conventional pipe support 10 is manufactured by separating the outer pipe 1 and the inner pipe 2 and adjusting the height (length of use) by inserting the inner pipe 2 into the outer pipe 1 at an appropriate depth.

At this time, in order to fix the outer tube 1 and the inner tube 2 at the fitting positions, the pipe support 10 has the following structure.

The outer shell 1 is provided with a male thread 3 formed on the outer surface of the end portion where the inner tube 2 is inserted and an adjusting female thread 4 screwed to the male thread 3. At this time, the male screw (3) forms a narrow and long slot in the longitudinal direction.

A plurality of pin holes 9 are formed in the inner tube 2 at predetermined intervals. When the inner tube 2 is inserted into the outer tube 1, the pin hole 7 is aligned with the position of the long hole.

Therefore, after inserting the inner tube 2 into the outer tube 1, the support pin 7 is inserted into the elongated hole and the pin hole 9 at the same time, and the lower end of the support pin 7 is inserted into the female screw 4 The position of the outer tube 1 and the inner tube 2 can be fixed.

Reference numeral 8 denotes a support pin connecting ring for preventing the support pin 7 from being lost.

The general pipe support is provided with a bottom plate 5 and a receiving plate 6 having an enlarged area so that both ends can contact the bottom face 12 and the form 11 and can be slidably supported.

On the other hand, according to national regulations, pipe supports shall be able to withstand loads of at least 4 tons.

However, the pipe supports used in the actual field often fail to satisfy the allowable load due to manufacturing defects or deterioration due to repeated use.

Such a pipe support, even if it receives a compressive load within the allowable range, causes deformation such as buckling, which causes the structure collapse.

However, the deformation of the buckling or the like occurs intensively in the inner pipe 1 where the compressive strength is lowered because the diameter is smaller than that of the outer pipe 2. In order to solve such a problem, a technique for reinforcing the compressive strength of the inner pipe of the pipe support has been disclosed in Korean Patent Laid-Open Publication No. 2014-0008831 (Publication date 2014.01.22).

The present invention relates to a mobile fastening device for buckling prevention that covers a hollow tube which can be moved in the longitudinal direction of an inner pipe around an inner pipe of a pipe support, and a connecting bracket is formed on the hollow pipe to fasten the horizontal material.

The prior art of the above-mentioned patent discloses an effect of reinforcing an inner tube portion vulnerable to buckling in a support since the movable fastening device is mounted over the inner tube.

However, since the movable fastening device is in the form of a hollow tube separated from the pipe support, there is inconvenience that the connecting member is inserted into the fastening hole at the work site to be assembled with the inner pipe. Accordingly, There is a problem that the time increases.

Korean Patent No. 10-0455910 (registered Nov. 10, 2004) also discloses a technique for fastening a connector pipe to an inner pipe of a pipe support.

The connection pipe of the above-mentioned patent is described as a constituent element for installing a bridged bracket-supporting stand, but it has a similar effect to that of Korean Laid-Open Patent No. 2014-0008831 in that it forms a hollow tube surrounding the inner tube You can do it.

However, since the connecting pipe of this patent is also separated from the pipe support, it has the same problems as the Korean Patent Laid-Open Publication No. 2014-0008831, which requires assembly with an inner pipe using a bolt and a fixing knob at a work site.

Korean Laid-Open Patent Application No. 2014-0008831 (Publication date 201.01.22.) Korean Patent No. 10-0455910 (registered on Nov. 10, 2004)

2 to 6 show concrete examples of the pipe support reinforced with the compressive strength according to the present invention. Figs. 2 to 6 show a reinforcing part 60 7 to 9 show an example 1 in which a reinforcing portion 60 is additionally provided to an existing pipe support whose compressive strength is less than the specified value due to aging or the like to reinforce the compressive strength. .

[Example 1]

Embodiment 1 of the present invention will be described with reference to Figs. 2 to 6. Fig.

The pipe support 100 of the present invention shown in FIG. 2 differs from the conventional pipe support 10 shown in FIG. 1 in that a reinforcing portion 60 is further formed.

This reinforcing portion 60 is provided on the upper portion of the inner tube 2. One end of the reinforcing portion 60 is connected to the upper end portion of the inner tube 2 and the other end is connected to the lower end of the receiving plate 6 . The coupling between the reinforcing column 20 and the inner pipe 2 is made via the adapters 40 and 50.

The length of the inner tube 2 can be made shorter by the length of the reinforcing struts 20 because the reinforcing struts 20 are attached to the upper end of the inner tube 2 of the first embodiment of the present invention. That is, the inner tube 2 of FIG. 2 is much shorter than the inner tube 2 of the conventional pipe support shown in FIG.

However, the inner pipe 2 of FIG. 2 is more resistant to buckling than the inner pipe 2 of the prior art of FIG. 1 because the shorter the length of the same diameter pipe, the greater the buckling load.

3 and 5 illustrate the adapters 40 and 50 that are sandwiched between the reinforcing struts 20 and the inner tube 2 to facilitate connection of the two hollow tubes. Each adapter will be described below.

3 (a) is a perspective view of the adapter 40, and FIG. 3 (b) is a cross-sectional view of the adapter 40 cut vertically on line C-C ' FIG.

The illustrated adapter 40 is of a short cylindrical shape with a protrusion 45 formed therein. It is preferable that the protruding portion 45 is formed in an annular shape so that a space S is provided therein. If necessary, the projecting portion 45 may be extended to form the valve portion S as a clogged valve.

The adapter 40 is formed so that the upper cylinder of the projection 45 has a larger inner diameter than the lower cylinder. Accordingly, as shown in FIG. 4, the upper portion of the cylinder receives the reinforcing column 20 having a large outer diameter, and the lower portion receives the inner tube 2 having a small outer diameter.

The upper surface of the protruding portion 45 is a reinforcing support seating surface 47 where the end surface of the reinforcing support 20 is positioned and the lower surface of the protruding portion 45 is an inner surface of the inner pipe 2, And becomes the seating surface 49.

3, the thin cylinder formed on the upper side of the projection 45 of the adapter 40 becomes the reinforcing strut guide 42. [ This reinforcing pillar guide 42 assists insertion of the reinforcing pillar 20 and allows it to be fixed in place. The inner side surface of the reinforcing pillar guide 42 becomes the reinforcing pillar guide surface 43. [

The thick cylinder on the lower side of the projection 45 becomes the inner tube guide 42-1. This inner tube guide 42-1 allows the inner tube 2 to be inserted and fixed in place, and its inner surface becomes the inner tube guide surface 43-1.

4 is a cross-sectional view of the portion A indicated by a dotted circle in Fig. 2 in detail.

The reinforcement column 20 and the inner tube 2 are inserted into the upper and lower portions of the adapter 40 as shown in Fig.

When inserting the reinforcing struts 20 and the inner tube 2 into the adapter 40, the worker grips the outer surface 46-1 of the adapter and presses the reinforcing column guide surface 43 and the inner tube guide surface 43-1 Push it along. The setting is completed when the end face of the reinforcing support 20 and the end face of the inner pipe 2 contact the reinforcing support seating face 47 and the inner seating seating face 49, respectively.

In this work process, the central axis for preventing the eccentricity of the reinforcing struts 20 and the inner pipe 2 is automatically adjusted even if they do not work separately. Therefore, even beginners can easily work, can also speed up the work.

The reinforcing pillars 20 and the inner pipe 2 sandwiched between the adapter 40 and the inner pipe guide 42-1 are held in position by the reinforcing strut guide 42 and the inner pipe guide 42-1, The welding work for forming the workpiece W becomes easy.

The welded portion W is formed along the circumference at a point where the upper surface 44 of the adapter 40 meets the outer surface of the reinforcing strut 20 and at a point where the bottom surface 48 of the adapter meets the outer surface of the inner tube 2 .

When the welded portion W is formed in this way, the reinforcing column 20 and the inner pipe 2 can be integrally and firmly coupled to each other via the adapter 40. [

On the other hand, the space S in the adapter 40 is a space for absorbing the thermal expansion occurring in the adapter 40 during the welding operation. Therefore, if the space S is provided, the quality deterioration due to thermal deformation of the adapter 40 can be reduced.

For reference, the receiving plate 6 and the reinforcing column 20 shown in Fig. 2 are joined by welding. This is the same operation as welding the receiving plate 6 and the inner tube 2 in the conventional pipe support of Fig.

5 (a) is a perspective view showing the entire outer shape of another adapter 50, and FIG. 5 (b) is a view showing an adapter 50 Fig.

The illustrated adapter 50 has a short cylindrical shape with a protruding portion 55 formed outward, and the inside of the cylindrical portion is made into a space portion S. If necessary, it may be manufactured in a clog-free structure without any space.

The projecting portion 55 is formed in an annular shape.

The adapter 50 is formed such that the upper cylinder of the projection 55 has an outer diameter larger than that of the lower cylinder. Therefore, as shown in Fig. 6, the upper part of the cylinder is inserted into the inside of the reinforcing column 20 having a large inside diameter, and the lower part is inserted into the inside pipe 2 having a small inside diameter.

The upper surface of the projecting portion 55 serves as a reinforcing support seating surface 57 on which the end surface of the reinforcing support 20 is positioned and the lower surface of the projecting portion 55 serves as a reinforcing support seating surface 57 on which the end surface of the reinforcing support 20 is located. And becomes the seating surface 59.

5, the thick cylinder on the upper side of the projecting portion 55 of the adapter 50 becomes the reinforcing strut guide 52. As shown in Fig. The reinforcing strut guide 52 facilitates insertion of the adapter 50 into the reinforcing struts 20 and allows the reinforcing struts 20 to settle in place. The outer surface of the reinforcing pillar guide 52 becomes the reinforcing pillar guide surface 53.

The thin cylinder at the lower side of the projection 55 becomes the inner tube guide 52-1. This inner guide 52-1 makes it easier to insert the adapter 50 into the inner tube 2 and allows the inner tube 2 to settle in place. The outer surface of the inner tube guide 52-1 becomes the inner tube guide surface 53-1.

6 is a cross-sectional view of a portion A indicated by a dotted circle in Fig. 2 in detail.

6, the reinforcement column 20 and the inner tube 2 are fitted on the upper and lower sides of the adapter 50, respectively.

When the reinforcing struts 20 and the inner tube 2 are fitted to the adapter 50, the worker grasps the outer surface 56-1 of the adapter and moves along the reinforcing column guide surface 53 and the inner tube guide surface 53-1 Push it. Setting is completed when the end face of the reinforcing stalk 20 and the end face of the inner pipe 2 touch the reinforcing seat seating surface 57 and the inner tube seating surface 59, respectively.

Even in this case, the central axis for preventing the eccentricity of the reinforcing column 20 and the inner pipe 2 is automatically adjusted without any additional work. Therefore, even beginners can easily work, can also speed up the work.

The reinforcing column 20 and the inner pipe 2 sandwiched between the adapter 50 and the inner pipe guide 52-1 are held in the correct positions by the reinforcing strut guide 52 and the inner pipe guide 52-1, W is formed easily.

The welded portion W is formed at a point where the reinforcing support seating surface 57 meets the end of the reinforcing support 20 and at a point where the inner seating surface 59 and the outer surface of the inner pipe 2 meet.

The welded portion W can be formed and the reinforcing column 20 and the inner pipe 2 can be integrally and firmly coupled to each other via the adapter 50. [

[Practical example 2]

A second embodiment of the present invention will be described with reference to Figs.

7 is a top view of a pipe support according to the present invention. In comparison with the conventional inner pipe 2 shown in FIG. 1, a reinforcing portion 60 is further formed.

The reinforcing portion 60 is provided on the upper portion of the inner pipe 2 and is configured in the form of a double pipe in which the upper end of the inner pipe 2 is inserted by using a reinforcement column 20 in the form of a hollow pipe. The coupling between the reinforcing pillars 20 and the inner pipe 2 is carried out via the adapter 30.

The reinforcing pillars 20 are in the form of elongated hollow tubes whose compression strength is stronger than that of the inner tube 2 since the diameter thereof is larger than that of the inner tube 2. Normally, the reinforcing struts 20 can be made of the same hollow tube as the outer tube.

The upper end of the inner tube 2 of the second embodiment of the present invention is inserted into the reinforcing column 20 as shown in Fig. Therefore, the length of the inner tube 2 exposed to the single tube in Example 2 is much shorter than the inner tube 2 of the conventional pipe support shown in FIG.

However, in the case of a pipe of the same diameter, the shorter the length is, the larger the buckling load is. Therefore, the inner pipe 2 of FIG. 7 is more resistant to buckling than the conventional inner pipe 2 of FIG.

8 illustrates an adapter 30 interposed between the reinforcing struts 20 and the inner tube 2 to facilitate the coupling of the two hollow tubes.

8 (a) is a perspective view of the overall appearance of the adapter 30. FIG. 8 (b) is a cross-sectional view of the adapter 30 cut vertically on the line C-C ' FIG.

The illustrated adapter 30 is of a short cylindrical shape with its lower portion curved inwardly to form a protrusion 35. The projecting portion 35 is formed in an annular shape so that the penetrating portion T must be formed inside.

9, the adapter 30 receives a reinforcing column 20 having a large outside diameter on the upper side of the cylinder, and the inner tube 2 having a small outside diameter passes through the penetrating portion T. As shown in FIG.

The upper surface of the projecting portion 35 is a reinforcing landing seating surface 37 on which the end face of the reinforcing support 20 is located.

Referring to Fig. 8, the cylindrical body on the upper side of the projection 35 of the adapter 30 becomes the reinforcing pillar guide 32. Fig. The reinforcing pillar guide 32 assists insertion of the reinforcing pillar 20 and allows it to be fixed in place. The inner side surface of the reinforcing pillar guide 32 becomes the reinforcing pillar guide surface 33. [

The protruding end surface 36 formed on the inside of the adapter 30 serves as a guiding surface for assisting insertion of the inner tube 2 into the reinforcing column 20 and fixing the same in place.

The inner tube 2 is passed through the inner penetration portion T formed by the protruding end surface 36 formed inside the adapter 30 to receive the inner tube 2 into the reinforcing strut 20 .

Fig. 9 specifically shows a cross section of a portion A indicated by a dotted circle in Fig.

9, the reinforcement column 20 is inserted into the upper portion of the adapter 30, and the inner tube 2 is inserted into the reinforcement column 20 through the adapter 30, It becomes a form to be combined by mediation.

When the reinforcing struts 20 and the inner tube 2 are joined by the adapter 30, the following is performed.

7, it is inserted into the reinforcing column 20 from the upper portion of the inner tube 2. In this case, The worker holds the outer surface 36-1 of the adapter 30 so that the upper end of the inner tube 2 touches the receiving plate 6 of the reinforcing column 20, The adapter 30 is inserted from the bottom of the housing 2.

9, the end of the reinforcement column 20 is inserted into the adapter 30 and the end of the reinforcement column 20 (Fig. 9) 20 abuts on the reinforcement landing surface 37. At this time, the protruding end surface 36 is in contact with the outer peripheral surface of the inner tube 2, and the setting is completed.

The reinforcing pillars 20 and the inner pipe 2 sandwiched between the adapters 30 are held in place by the adapter 30 so that the welding work for forming the welds W shown in Fig.

The welded portion W is formed at a point where the upper surface 34 of the adapter 30 meets the outer surface of the reinforcing strut 20 and at a point where the outer surface of the inner tube 2 meets the bottom surface 38 of the adapter. When the welded portion W is formed in this way, the reinforcing struts 20 and the inner pipe 2 can be integrally and firmly connected to each other via the adapter 40. [

It is also preferable that the receiving plate 6 and the reinforcing support 20 shown in Fig. 7 are also welded to each other.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
