Description

Bracket Assemblies for Building Facilities {Bracket Assemblies for Building Facilities}

The present invention relates to a bracket assembly for construction facilities, and more particularly, to a frame guide that can be used for various purposes through a medium of a bracket firmly coupled to a fixed construction facility such as an H beam or a wall, which can be conveniently and strongly coupled to a construction facility. It relates to a bracket assembly that simultaneously provides facility stability as well as convenience in maintenance.

There are quite a lot of building facilities or building structures installed in buildings, and one of them is a cable.

Cables are installed to supply power to various equipment such as electronic equipment as well as communication equipment and data processing equipment or to process data, and are usually wired along the ceiling or wall of a building.

However, cables exposed to walls or ceilings are aesthetically quite messy, and there is a possibility of collision or interference with each other.

In order to prevent this problem, a technique of installing a mold or a tray capable of neatly accommodating the cables has been disclosed.

The wire cable tray of the building apartment house, which is Korean Patent No. 2262934, individually accommodates multiple cables so that when replacing one cable, it is possible to separate and replace only the cable that needs to be replaced while maintaining the fixed state of the other cable. On the other hand, it is disclosed that it is possible to prevent shaking of the extension part and the detachable frame due to the space between the mounting hole and the mounting anchor.

However, in the above technology, the volume of the tray is unnecessarily large, and it is difficult to fix and connect the tray to the wall of the building, etc., and it is cumbersome to remove the entire tray from the wall or the like again during subsequent repair work after fixing to the wall. There is a disadvantage in that a convenient means for attachment or separation has not been adequately provided.

In addition, a tray having a structure elongated in a bar type along the cable extension direction may be temporarily connected to a peripheral frame as well as a silk cable, but a problem of not supporting these additional functions may also be pointed out.

Therefore, it is a new and advanced product that can be conveniently and firmly fixed to building facilities such as walls with simple manual work of frame guides that have various uses that can not only accommodate cables neatly but also connect and support frames such as surrounding posts. There is a need to develop a structure for building facilities.

As can be seen from FIG. 2, the bracket 100 of the present invention is based on including a coupling part 110, an extension part 120, and a fastening hole 130.

The bracket 100 having such a detailed structure can be implemented in various embodiments, and it can be understood that FIG. 2 shows a first embodiment among various embodiments of the bracket.

Specifically, as can be seen in FIG. 2, the coupling portion 110 is a portion that is fitted into the coupling medium of the building facility in a c-shaped state, and includes first and second coupling portions 111 and 112 and a connection portion 113 do.

The first and second coupling parts 111 and 112 are portions extending in parallel to each other with a predetermined length in a state spaced apart from each other by a predetermined distance, and the connecting portion 113 is a kind of plate-shaped body connecting the inner ends of the first and second coupling parts 111 and 112. I mean block.

That is, the structure of the first and second coupling portions 111 and 112 and the connection portion 113 has a c-shape, and the construction facility 1 (specifically, the coupling of the building facilities) is formed in the space between the first and second coupling portions 111 and 112. medium) can be fitted.

The extension part 120 is a structure that extends to a certain length from one side of the coupling part 110. At this time, the extension part 120 extends at various positions of the coupling part 110 according to the extension direction of the frame guide 200. it is possible to become

First, in FIG. 2 , the extension part 120 has a structure extending a certain length along the same line as the first and second coupling parts 111 and 112 on the side opposite to the first and second coupling parts 111 and 112 .

At this time, the extension length of the extension part 120 determines the volume slidingly coupled to the frame guide 200, and may be manufactured in various sizes in consideration of the entire length of the frame guide 200.

That is, the extension part 120 according to FIG. 2 can be applied to a structure in which the frame guide 200 extends on the same line as the first and second coupling parts 111 and 112, that is, protrudes from the building facility 1. It is specialized to be coupled to the frame guide 200 extending along the protruding direction of the coupling medium 2 .

Of course, the extension part 120 is not limited to this, and as shown in FIG. 6, when the frame guide 200 extends in the vertical direction with the coupling medium 2 of the building facility 1, the position of the extension part 120 It can be different, and as shown in FIG. 7, it is also possible to have a three-dimensional shape of a hexahedron 121 having a hollow 122 on one side of the outer surface of the coupling part 110 to accommodate the frame guide 200.

In summary, the extension part 120 can be extended at various positions of the coupling part 110 according to the extension direction of the frame guide 200 with respect to the building facility 1 .

A fastening hole 130 is formed through at least one side of the coupling part 110 and the extension part 120 .

Fastening holes 130 provide a space in which fasteners such as bolts or screws are fastened, and in FIG. 2, two are formed in the first coupling part 111 so that the building facility 1 (corresponding location of the building facility) Of course, a fastening hole is formed) as well as providing a solid coupling with the frame guide 200 (also two are formed on one side (side) of the extension 120 and slidably coupled to the extension 120) , A fastening hole is also formed at the corresponding position of the frame guide) can provide a solid coupling relationship to prevent separation.

These fastening holes 130 are at least one number at various positions for at least one of the coupling part 110 and the extension part 120 according to the position of the building facility 1 and the frame guide 200, for example It is possible to form through 1 to 3 pieces.

3 is a perspective view illustrating a state in which cables are accommodated in a frame guide, and FIG. 4 is a perspective view illustrating a state in which a holding is connected to a frame guide.

The frame guide 200 of the present invention is a structure that is slidably coupled to the extension 120 of the bracket 100 in a c-shaped state, and accommodates the cable 10 in the internal space secured by the c-shape or otherwise It can provide a role of supporting/connecting a separate building structure installed around it with a structural feature that is elongated in the shape of a bar.

Specifically, the frame guide 200 includes the first and second side walls 210 and 220 extending a certain length in parallel with each other and the bottom surface 230 connecting the ends of the first and second side walls 210 and 220 to have a c shape as a whole. have That is, it can be seen that the frame guide 200 has a structure in which one side (the opposite side of the bottom side) and the side of both ends are open.

The first and second sidewalls 210 and 220 of the frame guide 200 may be erected in the upward direction of the building facility or may extend in the horizontal direction of the building facility 1 (see FIG. 5). In other words, it means that the extension directions of the first and second side walls 210 and 220 can be processed in various ways according to various environments of the building facility 1 .

Referring to FIG. 3 , it can be seen that the cable 10 is accommodated in the inner space of the frame guide 200 having the first and second side walls 210 and 220 and the bottom surface 230 .

At this time, the cable 10 may supply electricity to various electrical facilities, lighting, switchboards, etc., or may be made of the same type as communication lines or data processing lines for communication equipment or controllers, and the first and second side walls 210 and 220 of the frame guide 200 In the inner space surrounded by and the bottom surface 230, one strand as well as several strands may be accommodated.

That is, the frame guide 200 of FIG. 3 is installed in the path through which the cable 10 passes, and provides a function of accommodating the cable 10 neatly and stably.

In addition, as can be seen from FIG. 4, the frame guide 200 of FIG. 4 can provide a role of supporting the holding by combining the surrounding posts and a separate bracket provided to connect them, and the frame guide While receiving a portion of the bracket 100, that is, a portion of the extension portion 120, in the aforementioned internal space of the 200, it is possible to support a post extending in a direction perpendicular to the extension direction of the frame guide 200.

As such, the frame guide 200 is an important structure in the building facility 1 that can be used for various purposes, and can be extended in various directions in the space within the building facility depending on the purpose, and supports the frame guide 200 itself. The means by which it can be done will also be important.

That is, the key function of the bracket assembly of the present invention is to present a structure in which the frame guide 200 is coupled to the bracket 100 to pursue convenience and structural stability at the same time.

Figure 5 is a perspective view illustrating a state of sliding coupling of the frame guide to the bracket coupled to the building facility of the present invention.

As can be seen in FIG. 5, the bracket 100 is first coupled to the building facility 1, and then the frame guide 200 is manually slid and moved by the operator toward the extension 120 of the bracket 100. It is possible to receive and couple the extension part 120 to the space between the first and second side walls 210 and 220 and the bottom surface 230 of the 200 . Of course, not only the manual work of the operator but also tools or known bonding aids may be utilized.

Alternatively, after the primary coupling of the frame guide 200 and the bracket 100, the bracket 100 may be secondary coupled to the building facility 1.

At this time, it goes without saying that the bracket 100 can be firmly coupled to the building facility 1 or the frame guide 200 by fastening the fasteners F according to the number and location of the fastening holes 130 .

In summary, the bracket assembly of the present invention is safe for construction facilities such as walls simply and conveniently by sliding the frame guide 200, which can be used for various purposes such as cable installation, support connection, etc., using the bracket 100 as a medium. and provides the characteristics of being able to bond firmly.

6 is a perspective view showing a second embodiment of the bracket of the present invention.

Unlike the bracket 100 of FIG. 2, in the bracket 100 according to FIG. 6, the extension part 120 has a normal line on the surface of the outer surface of the second coupling part 112 (the wide surface opposite the first coupling part) ) provides a structure elongated in the direction. Such a bracket 200 may be suitably applied to a structure in which the frame guide 200 extends in a vertical direction, not in the same line as the coupling medium 2 of the building facility 1.

Furthermore, based on the installation position of the above-described extension part 120 with respect to the bracket 100 of FIG. 6, the first coupling part 111 in the bracket 100 of FIG. It is preferred that it is elongated to a short length. That is, it means that the second coupling part 112 extends longer than the first coupling part 111 .

Specifically, due to the structure in which the extension part 120 extends from the second coupling part 112 side, the frame guide 200 coupled to the extension part 120 extends in the direction of gravity or the upper part of the building facility 1 Since the load of the frame guide 200 is concentrated on the side of the second coupling part 112 when it extends in the vertical direction toward the opposite direction, the area where the extension part 120 is supported so that the frame guide 200 can be supported more stably That is, the second coupling portion 112 is secured to be larger than the first coupling portion 111 .

Additionally, a plurality of teeth along the longitudinal direction of the second coupling portion 112 are provided on the inner surface of the second coupling portion 112 extending longer than the first coupling portion 111 (the surface opposite to the surface to which the extension unit is coupled). (齒形部) 140 is possible to be formed.

The teeth 140 can provide two functions. First, the teeth 140 are also provided on one side of the coupling medium 2 of the building facility 1 in contact with the teeth 140. It is possible to provide a basis that can be firmly combined with the bracket 100 even under the load of the frame guide 200 by forming a mutually interlocking coupling.

Second, when the teeth 140 come into contact with one side of the coupling medium 2 of the building facility 1 made of a flat surface, they do not adhere perfectly due to the valley/floor structure of the teeth 140. As a reaction to this, a kind of micro gap is generated, and as a reaction to this, the other side surface of the coupling medium 2 comes into close contact with the inner surface of the first coupling portion 111, which will be described later, on the inner surface of the first coupling portion 111 By stacking the auxiliary binding pad 150, the shock mitigation and auxiliary bonding function of the auxiliary binding pad 150 are further maximized to provide a basis for processing.

In addition, as can be seen from FIGS. 2 and 6 , the frame guide 200 includes a bent portion 240 bent and extended to face each other at the ends of the first and second side walls 210 and 220, and corresponding to this, the extended portion Corners of 120 may be chamfered.

This structure is processed to more naturally implement the sliding coupling force between the coupling parts of the frame guide 200 and the extension portion 120 .

In other words, if an angled corner is formed in the extension part 120, the frame guide 200 may be tightly coupled or may not slide properly. The chamfered corner of the extension part 120 provides a more natural and smooth sliding coupling.

7 is a perspective view showing a third embodiment of the bracket of the present invention.

In the bracket 100 of FIG. 7 , it can be seen that the extension part 120 is formed of a hexahedron 121 having a hollow 122 in a state in which one surface is coupled to the outer surface of the second coupling part 112. That is, a structure in which the end of the frame guide 200 can be fitted into the hollow 122 of the extension 120 is proposed.

Like the bracket 200 of FIG. 6, the third embodiment of the bracket 200 according to FIG. 7 has the extension 120 formed on the outer surface of the second coupling part 112, and is the same as the construction facility 1. Applied to a structure in which the frame guide 200 extends in a non-linear direction (eg, the same as the protruding direction of the coupling medium of the building facility, but with a height difference), which is not shown in the drawings, but is shown in FIG. Like the bracket 200, it is also possible to include a structure in which the length difference between the first and second coupling parts 111 and 112 and the toothed part 140 are formed.

7, the frame guide 200 is seen to be shown in an L-shape, but the frame guide 200 accommodated in the hollow 122 of the extension 120 is based on taking a U-shape as mentioned above.

According to the bracket 200 of FIG. 7 described above, the contact area with the frame guide 200 is increased according to the structure of the hexahedron 121 surrounding the hollow 122 so that the frame guide 200 and the bracket 100 are more stably attached. Not only can they be combined, but they also have characteristics that can ensure a more intuitive and convenient coupling state between the two.

8 is a perspective view showing a structure in which an anti-loosening pin is additionally installed in the bracket of FIG. 6;

Referring to FIG. 8 , it can be seen that an anti-loosening pin 160 is additionally installed in the bracket 200 of FIG. 6 . Of course, in FIG. 8, the bracket 200 of FIG. 6 is shown as a reference, but it is not necessarily limited thereto, and it is possible that the anti-loosening pin 160 is added to the bracket 200 of FIGS. 2 and 7.

Specifically, as can be seen in FIG. 8, the above-described fastening hole 130 is on one side of the coupling part 110 (of course, it is not necessarily limited to this position, and the other surface of the coupling part 110 or the extension part 120) A fastener (F) is inserted into each of the fastening holes 130 in a state where the two fastening holes 130 pass through each other in a state adjacent to each other, and the auxiliary fastening hole 161 penetrates between the two fastening holes 130. In this state, the anti-loosening pin 160 can be installed in the auxiliary fastening hole 161. At this time, the anti-loosening pin 160 provides a function of preventing unnecessary rotation of the fasteners (F) by being in close contact with the outer circumferential surface of each fastener (F).

Preferably, the outer circumferential surface of the anti-loosening pin 160 is formed with a thread or an angled structure so that it can provide an engaging action to the adjacent fastener F more efficiently.

In summary, the anti-loosening pin 160 has a characteristic of preventing the fastener F from being loosened or loosened due to unnecessary rotation in the fastening hole 130 .

9 is a perspective view showing a structure in which an anti-loosening cover is additionally installed on the bracket of the present invention.

As can be seen from FIG. 9 , it is possible to form an anti-loosening cover 170 (cover or cap) around the fastening hole 130 to which the fastener F is fastened.

This anti-loosening cover 170 is composed of a three-dimensional shape such as a rectangular parallelepiped having an internal space and serves to cover the upper portion of the fastener F. Take an open-and-close structure.

The release-preventing cover 170 may be made of a transparent material or an opaque material. That is, it is not limited to the material.

Due to the rotational structure of the anti-loosening cover 170, when the fastener F is fastened to the fastening hole 130, the anti-loosening cover 170 is opened, and when the fastening of the fastener F is completed, the anti-loosening cover is closed. The fastener F may be covered by covering 170 in a hinged rotation manner.

According to this anti-loosening cover 170, by covering the fastener F so that the fastener F is not exposed to the outside, the fastener F is protected to prevent collision with other objects around it, so that the fastener F is easily prevented by the above-mentioned collision or the like. Provides characteristics capable of excellently and efficiently preventing problems such as loosening of the fastener F or breakage of the head of the fastener F.

FIG. 10 is a perspective view illustrating a state in which an auxiliary bonding pad is attached to the bracket of FIG. 6 .

In the case where the contact surface of the frame guide 200 is a flat surface in the state where the teeth 140 are formed on the inner surface of the second coupling part 112 in the bracket 100 of FIG. 6 described above, the contact surface of the frame guide 200 and While a separation occurs between the teeth 140, one side of the frame guide 200 may be pushed toward the inner surface of the first coupling portion 111 and may have a property of contacting. At this time, the first coupling portion 111 If the inner surface is not treated differently, damage such as unnecessary adhesion between the inner surface of the first coupling part 111 and one surface of the frame guide 200 may occur or cracks may occur due to excessive adhesion.

In order to prevent this problem, as can be seen from FIG. 10 , an auxiliary bonding pad 150 may be attached or stacked on the inner surface of the first coupling part 111 .

The coupling auxiliary pad 150 is a kind of sheet having an appropriate thickness and is made of an elastic material to efficiently prevent adhesion caused by the reaction of the frame guide 200 caused by being spaced apart from the teeth 140 formed on the second coupling portion 112. It provides a function to prevent or absorb shock. In addition, the coupling auxiliary pad 150 provides a base that can be tightly coupled to the frame guide 200 without any separation space, and as a result, may assist in solid coupling of the extension portion 120 and the frame guide 200. .

Furthermore, in order to further enhance the durability of the auxiliary coupling pad 150, it is more preferable that the auxiliary coupling pad 150 is made of a double material.

Specifically, the bonding auxiliary pad 150 is made of an elastic material and is coated on a base attached to the inner surface of the first coupling part 111 and a surface of the base (opposite surface of the attachment surface of the base) and includes ethyl cellulose It may include an elastic auxiliary agent that does.

Preferably, the bonding auxiliary pad 150 may be composed of 90 to 99 parts by weight of the base and 1 to 10 parts by weight of the elastic auxiliary agent.

In this case, the base may be made of various known elastic materials, for example, engineering plastics having elasticity such as rubber and polyurethane, and is not limited to a specific elastic material.

The elastic auxiliary agent takes the structure of a layer or sheet laminated on a layer or sheet called a base, which is also made of an elastic material, but particularly includes ethyl cellulose.

Ethyl cellulose is obtained by ethyl etherifying the hydroxyl group (-OH) of cellulose, and has characteristics of high salt resistance and pH stability, and also has excellent mixing properties and thickening properties, thereby adjusting the hardness of the elastic material to an appropriate level.

Therefore, when the elastic auxiliary agent including ethyl cellulose is laminated on the base, the overall salt resistance and pH stability of the bonding auxiliary pad 150 are improved, and the frame guide 200 is balanced with the inner surface of the first coupling part 111 When adhesion occurs or an unbalanced bonding position is taken, the bonding auxiliary pad 150 with improved elasticity and hardness is adjusted by improving the thickening property is in close contact with the frame guide 200 to apply shock to the bonding auxiliary pad ( 150), which provides the effect of more smooth dispersion.

Furthermore, the elastic auxiliary agent may further include an additional composition in addition to ethyl cellulose. More preferably, the elastic auxiliary agent may further include lecithin and butyl carbitol acetate in addition to the above-described ethyl cellulose.

Since lecithin performs the function of a natural antifoaming agent, it is environmentally friendly and has the effect of preventing unnecessary air bubbles from being generated on the surface of the bonding auxiliary pad 150 to which the manufactured elastic auxiliary agent is added to show an even surface, and furthermore, the elastic auxiliary agent It performs the function of improving the mixing of various materials included in and imparting flexibility to the surface of the bonding auxiliary pad 150.

Butylcabitol acetate serves as a thickener to increase the viscosity of the elastic auxiliary agent reduced due to lecithin, assists the function of ethyl cellulose, and further serves as a solvent for resin-based components included in the elastic auxiliary agent. It is added to improve the mixing of various ingredients.

Therefore, according to the elastic auxiliary agent containing ethyl cellulose, lecithin, and butylcabitol acetate, it goes beyond the basic function of absorbing and dispersing shock while improving salt resistance and pH stability, removing air bubbles from the surface of the bonding auxiliary pad 150 and mixing It has the advantage that viscosity and elasticity are not reduced while increasing stability.

Furthermore, the elastic auxiliary agent may be prepared to double its properties through a process of mixing in stages while including additional materials other than the above-mentioned materials. The elastic auxiliary agent of the invention may be prepared through the steps of preparing a primary solution (S11), preparing a secondary solution, (S12) and (S13) completing the elastic auxiliary agent.

(S11) preparing a primary solution

First, a primary solution is prepared by mixing 20 to 40 parts by weight of ethyl cellulose, 10 to 30 parts by weight of polyisobutylene, and 30 to 70 parts by weight of xylene.

As described above, ethyl cellulose has characteristics of high salt resistance and pH stability, and furthermore, it is a material having excellent mixing properties and thickening properties.

Polyisobutylene is a synthetic rubber composed of a polymer of 2-methyl-1-propene. It is a colorless or light yellow, tenacious, elastic rubber-like semi-solid, environmentally friendly enough to be added to food, and harmless to the human body. It has the function of assisting the hardness and elasticity control effect of ethyl cellulose by adjusting the hardness to show an appropriate level of hardness and imparting flexibility.

These ethyl cellulose and polyisobutylene are dissolved using xylene, which easily dissolves organic matter, as a solvent to form a primary solution.

(S12) preparing a secondary solution

Next, a secondary solution is prepared by mixing 90 to 96 parts by weight of the primary solution with 3 to 5 parts by weight of lecithin and 1 to 5 parts by weight of potassium cocoyl glutamate.

As described above, lecithin prevents unnecessary bubbles from being generated on the surface of the auxiliary bonding pad 150 to which the elastic auxiliary agent is added, and furthermore, improves the mixing of various materials included in the elastic auxiliary agent and binds the auxiliary pad 150. ) It performs the function of imparting flexibility to the surface.

Potassium cocoyl glutamate is a coconut-based natural surfactant that can assist the function of the above-mentioned lecithin. It is environmentally friendly and at the same time plays an auxiliary role to increase the mixing of substances and separates between organic and inorganic substances included in elastic auxiliary agents. function to prevent

At this time, even if some unmixed solutes exist in the solvent in the primary solution, more even dissolution can occur by additional mixing of lecithin and potassium cocoyl glutamate, and further, additional hardness through the additional addition of lecithin and potassium cocoyl glutamate.

(S13) Step to complete the elastic auxiliary agent

Finally, 92 to 98 parts by weight of the secondary solution, 1 to 5 parts by weight of butyl carbitol acetate, and 1 to 4 parts by weight of Ghatti gum are mixed to complete the elastic auxiliary agent.

As described above, butylcabitol acetate serves to increase the viscosity of the elastic auxiliary agent to assist the function of ethyl cellulose and is added to enhance the mixing of various components.

Ghatti gum is a substance for increasing viscosity, enhancing emulsion stability, and improving physical properties and feel when mixed, and has excellent solubility and an excellent viscosity increasing effect. When added to the elastic auxiliary agent, it assists the function of ethyl cellulose and at the same time provides a function of improving the physical properties and touch of the bonding auxiliary pad 150 to which the elastic auxiliary agent is added.

Furthermore, through butylcabitol acetate and ghatti gum added last, it is possible to maintain the mixability while providing a gradual increase in viscosity and an elastic auxiliary effect, and finally, ghatti gum is filled to increase the reduced viscosity.

As such an elastic auxiliary agent is added to the binding auxiliary pad 150, the salt resistance and pH stability of the binding auxiliary pad 150 are increased, as well as the dispersion and buffering effect for impact by adjusting the hardness based on the gradual control. It can be increased, and furthermore, the texture or flexibility of the surface of the bonding auxiliary pad 150 can be improved, and at the same time, the mixing property of the elastic auxiliary agent itself can be increased and stability can be improved.

Furthermore, by adding these materials step by step, it has the property that hardness and viscosity can be easily adjusted to an appropriate level, and a solution with high stability can be prepared at each step, and at the same time, viscosity and elasticity are extremely high or low. be able to prevent
