Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an elastic jockey base,

The present invention relates to an elastic jockey base and a support, and more particularly, to an elastic jockey base and a support, which can adjust the height of a support while preventing collision between the jockey and the support at the time of lifting and supporting the support, The present invention relates to an elastic jockey base and a support including the elastic jockey base.

Generally, a mold is used to provide a concrete pouring space for building a concrete structure. The mold is supported by a single support, and the operation of connecting the single support to the multi-stage is difficult. In general, the ceiling of each floor of the building has a uniform height, and thus the support of the ready- .

Especially, in the case of concrete steel structure, it is necessary to support the concrete structure until the completion of curing after pouring concrete. At this time, a support is installed from the ground to support the work footrest and concrete structure.

The supports are supported directly on the ground at the bottom or through the jockey base for height adjustment. Therefore, since the supporting part having a larger cross-sectional area than the support should be formed at both ends in the longitudinal direction of the electron support, there is a problem in that the supporting part is deformed or broken during handling (storage, transportation, etc.) A problem that requires a separate configuration for connecting the jockey base to the support, and a problem that the jockey base of various sizes can not be connected.

1, the jacquie 1 according to the prior art is screwed on a base plate 2 supported on the ground, a screw rod 3 provided on the base plate 2, and a screw rod 3 And a height adjuster 4 that ascends and descends along the thread bar 3.

As shown in FIG. 2, the jig 1 having such a configuration is used in combination with a support 5. For example, as shown in FIG. 2, a product, in which a plurality of vertical supports 5 and a horizontal member and an inclined member are combined, And the jig 1 is coupled to the bottom of the vertical support 5 to be integrally used.

At this time, the support 5 is used in combination with the socket 7 to be coupled to the jaws 1. The socket 7 is composed of a large outer diameter of the threaded rod 3 and is coupled to the periphery of the threaded rod 3 and is connected to the support 5 by riveting while being supported by the height adjuster 4. In order to prevent the socket 7 from being detached from the screw rod 3, a support protrusion 8 for preventing the socket 7 from being detached is formed at the upper end of the screw rod 3. [

According to the conventional jacket 1 and the support 5 having such a configuration, the socket 7 connected to the support 5 is supported by the height adjuster 4 at a position spaced apart from the support jaw 8 , So that the support 5 is supported on the height adjuster 4 through the socket 7. When the height of the support 5 is required, the height adjuster 4 is turned in both directions to raise or lower the socket 7 to raise or lower the support 5.

However, according to the conventional jockey and support having such a configuration, there are the following problems.

The socket 7 is positioned below the support jaw 8 so as not to be normally supported by the height adjuster 4 and the support jaw 8 of the socket 7 and therefore when the support 5 is lifted in this state, And collide with the support jaws 7. Frequent collision of the support jaws 8 by the socket 7 due to frequent use of the support causes a problem that the jaws 1 are damaged.

This disadvantage leads to the separation of the jaw 1 and the support 5. Particularly during the lifting of the support 5, the height of the jaw 1 is increased, At this time, there is a problem that a safety accident of the operator is generated by the jockey 1 falling down to the ground and the building is damaged.

Patent Document 1 (Registration No. 10-0802165) includes a bottom plate supported on a floor; A screw rod mounted on the bottom plate and connected to a structure including a support; A height adjuster screwed to the screw thread to adjust a height of the structure while moving along the screw rod; Wherein the coupling means is coupled to the structure through a hinge and a free end portion is fastened with a bolt and a nut, And a rotation guiding protrusion protruding toward the inner diameter at the bottom of the first and second clamp pieces and connected to the rotation guiding groove spaced apart from the upper end of the height adjusting guide so as to idle, It is a clamping jockey base that binds the screw rod and the structure together. It can handle (install, transport, etc.) the support and jockey base in one process by combining the jockey base and the support as needed. It is possible to increase the efficiency of materials, but the structure is complex, Because it can not be manufactured through structural improvement, productivity is low because it requires new manufacturing facilities.

Patent Document 2 (Japanese Patent Application No. 10-1489386) discloses a socket which is provided with a support insertion groove therein and is coupled to the support insertion groove at one or more sides of a bottom and an upper portion of a vertically installed support; At least one fixture mounted on the socket body and fixing the socket body to the support; Shaped support portion formed at one or more sides in the longitudinal direction of the socket body at a larger cross-sectional area than the socket body, and is mounted on a bottom portion of the support to support the support on the ground, A socket for a building material support for fixing a jig base connected to a bottom of the support or connected to an upper portion of the supporter and having a support surface mounted on the bottom of the support, Since the support can be stably supported on the ground, the structure of the support can be simplified, and the height of the support can be easily adjusted because the jockey base can be connected to the support regardless of the size of the jockey base. Because the support can support the formwork in a stable manner It is possible to reduce the number of supports and to reduce the construction cost and to shorten the air by improving the working environment by securing a wide working space, It is possible to adjust the height of the jacquard rope so that the jockey can be lifted when lifting the system form.

As shown in FIG. 3, the elastic jockey base 10 according to the present invention includes a base plate 11 supported on the ground; A screw rod (12) mounted on the base plate (11); A height adjuster 13 screwed to the screw rod 12; A socket 14 coupled to the periphery of the screw rod 12 and supported by the height adjuster 13; (15) protruding from the upper end of the screw rod (12) toward the periphery of the screw rod (12); And a coil spring 16 which is provided between the socket 14 and the supporting jaw 15 and serves as an elastic member for supporting the socket 4 on the height adjusting tool 13. [

The base plate 11 may be configured with one or more anchor holes so that the bottom surface is seated on the ground, or may be fixed to the ground via an anchor while seated on the ground.

The screw rod 12 is in the form of a bolt having a screw thread formed on its outer circumferential surface and is fixed to the base plate 11 through a welding or the like in a state where it is erected.

The height adjuster 13 may be a nut having a female screw formed on an inner circumferential surface thereof so as to be screwed to the screw rod 12, and a knob (rod or the like) may be provided on the circumference to facilitate the height adjusting operation.

The socket 14 is formed in a ring shape and is coupled to the periphery of the screw rod 12 and has an inner diameter larger than the outer diameter of the screw rod 12 so that the height of the support pipe 20 can be freely adjusted.

The support jaw 15 prevents the support tube 20 from shaking through adjustment of the clearance with the support tube 20 and also supports the socket 14 and the coil spring 16 so as not to be detached from the screw rod 12 For example, a plate material having a cross-sectional area larger than that of the threaded rod 12, and may be screwed to the threaded rod 12 in the form of a nut welded to the upper end of the threaded rod 12 or provided with a female thread, There is an advantage that it is easy.

The upper end of the coil spring 16 is supported on the bottom surface of the support jaw 15 and the lower end of the coil spring 16 is supported on the upper surface of the socket 14. [

The length of the coil spring 16 will vary depending on the length of the screw rod 12 and the length of the socket 14 in such a manner that the socket 14 is held in close contact with the height adjusting hole 13, .

A support 100 having an elastic jockey base according to the present invention is composed of a support pipe 20 coupled to a socket 14 of a jaw 10 and a jaw 10.

The jaw 10 includes the above-described structure (base 11, screw rod 12, height adjuster 13, socket 14, and support jaw 15).

The support tube 20 is, for example, an aluminum tube having a hollow portion inside, and the jaws 10 are coupled to one or more sides in the longitudinal direction. A method of joining the socket 14 and the support pipe 20 with the rivetting 30 (see FIG. 3) by the combination of the support pipe 20 and the jaws 10, A method in which the socket 14 and the support pipe 20 are riveted and welded to each other; a method in which the support pipe 20 and the socket 14 and the screw rod 12 are passed through as shown in FIGS. 5 and 6; And a pin 40 (including a bolt and a nut) that can be used as a base. In the latter case, since the support pipe 20, the socket 14 and the screw rod 12 do not rotate, a coupling method of penetrating the support pipe 20 and the screw rod 12 is possible. A vertical rail 12a must be formed.

In the figure, the support tube 20 is shown to be coupled to the periphery of the socket 14, but it is also possible that the support tube 20 is inserted and coupled into the socket 14.

The operation of the jockey and the support according to the present invention is as follows.

3 is an initial state of the jockey 10. The height adjusting member 13 is screwed to the screw rod 12 so that its position does not change unless a rotational force is applied thereto. The socket 14 is held in close contact with the height adjusting hole 13 by the elastic force of the coil spring 16 which is supported on one side of the supporting jaw 15 because the position of the jaw 15 is not changed.

For example, as shown in FIG. 4, when a plurality of supports 100 of the present invention are coupled to a formwork 200 or a plurality of supports 100 are used as a system form connected through a connection member, The coil spring 16 is compressed by the self weight of the jockey 10 and the coil spring 16 is compressed by the self weight of the jockey 10. In this case, The socket 14 does not collide with the support jaw 15 by the coil spring 16 even if the socket 14 is compressed and the socket 14 is moved toward the support jaw 15.

Since the coil spring 16 has an elastic force that is compressed by an external force, when the height of the support is increased, the coil spring 16 is compressed during the forward rotation of the height adjuster 13, thereby not restraining the rotation of the height adjuster 13, The socket 14 can be raised by the sphere 13 and the height of the support can be increased. On the other hand, when the height of the support is lowered, the rotation of the height regulating member 13 is not restricted and the rotation of the height regulating member 13 is not constrained. Therefore, the height of the socket 14 is lowered by the height regulating member 13, The height can be lowered. That is, according to the present invention, since the height adjustment of the support 100 is not constrained, it is possible to prevent the collision between the jaw 10 and the support tube 20 in addition to the basic function of adjusting the support 100 to the design height, To prevent further damage.
