Description

Light-gauge steel frame slide joint of modular house and frame structure including same {LIGHT GAUGE STEEL FRAME SLIDE JOINT FOR UNIT MODULAR TYPE HOUSE AND FRAME STRUCTURE HAVING THEREOF}

The present invention relates to a lightweight beam frame slide joint for a modular house and a frame structure including the same. In more detail, the present invention relates to a frame slide joint that allows a frame structure to be manufactured by easily connecting a plurality of light beam steel frames in a house with a modular component prefabricated structure manufactured by a knock-down method, and a frame structure including the same. It's about.

A typical steel-framed house is built by erecting pillars on site after foundation construction, installing girders on the pillars, pouring concrete by combining floor form and rebar, and attaching non-structural walls. This conventional steel frame house construction method requires excessive effort and time for on-site work, and has the problem of showing significant differences in the degree of completion of the house depending on the skill level of the worker.

Accordingly, a modular construction method was developed that can ensure shortening of construction period and simplicity of construction. The modular construction method is a construction method that completes a house by pre-manufacturing module parts that attach walls to a rectangular parallelepiped frame structure connecting beams and columns at a factory, transporting the manufactured module parts to the site, and stacking them. As a result, the construction period was shortened and construction costs were reduced, and the dependence on workers' skills was greatly reduced. However, modules that are pre-manufactured in a factory like this incur excessive transportation costs due to their large volume, and there is a risk of damage during transportation. In particular, this disadvantage becomes more disadvantageous the longer the distance between the factory and the construction site, so it can act as a greater disadvantage in mountainous areas or areas with inconvenient transportation.

Therefore, recently, the knock-down method of modular house construction, which involves manufacturing most of the parts separately, transporting them to the site, and easily assembling the parts on site to complete the house, has been attracting attention.

Figure 1 is a diagram showing a conventional frame structure manufactured by a knockdown method. A plurality of columns 2 and beams 3 manufactured to a preset length are transported to the construction site and connected to each other at the construction site to form a frame structure 1. However, since the column 2 or beam 3 is made of steel or a steel alloy to withstand high loads, it is generally connected through welding. However, welding is a task that requires a high degree of skill, so it is impossible for the general public to perform it directly, and there is a problem that it takes a lot of time to manufacture the frame structure due to numerous welding operations.

In order to solve this problem, methods of connecting the column (2) and the beam (3) without welding using the frame joint (5) have been proposed. The frame joint 5 refers to a device that can firmly connect the columns 2 or beams 3 to each other without welding, an example of which is shown in FIG. 2. As shown in Figure 2, by inserting the pillar (2) or beam (3) between a pair of plates (6) and fastening a plurality of bolts (7), the pillar (2) or beam (3) can be connected to each other. Since this method does not require welding, even non-skilled workers can manufacture the frame structure themselves, but the work time increases due to too many bolts (7), and the combined columns (2) or beams (3) ), there is a problem that it is difficult to align them accurately.

The object of the present invention is to provide a lightweight steel frame slide joint that can easily and conveniently connect pillars and beams without welding, so that the general public can easily manufacture and construct a frame structure for a modular house.

Another task of the present invention is to provide a lightweight steel frame slide joint that can firmly connect columns or beams with a simple operation of inserting a fixing pin, thereby enabling the production of a sturdy frame structure in a short time.

However, the problem to be solved by the present invention is not limited to the above-described problem, and may be expanded in various ways without departing from the spirit and scope of the present invention.

In order to achieve the object of the present invention described above, the lightweight beam frame slide joint according to exemplary embodiments may have a first receiving portion and a second receiving portion coupled to the end of a column or beam of a modular house.

At this time, each of the first accommodating part and the second accommodating part is a housing accommodating the end of the pillar or the beam, is provided on the upper and lower surfaces of the housing, and protrudes from the outer surface of the housing to A pair of protrusions extending in the width direction, a pair of through holes each penetrating the protrusions in the width direction of the housing, and each inserted into the through holes to prevent the pillar or beam from being separated from the housing. It may include a pair of fixing pins for fixation.

In one embodiment, the lightweight beam frame slide joint may further have a third accommodating part orthogonal to the first accommodating part or the second accommodating part.

In order to achieve the object of the present invention, a lightweight beam frame slide joint according to another exemplary embodiment has a hollow bar shape, a plurality of lightweight beam frames cut to a preset length, and connecting the frames to each other. It may include at least one lightweight beam frame slide joint.

In this case, the lightweight beam frame slide joint may have a first receiving portion and a second receiving portion coupled to the end of the lightweight beam frame. In addition, each of the first accommodating part and the second accommodating part is a housing accommodating an end of the lightweight beam frame, is provided on the upper and lower surfaces of the housing, and protrudes from the outer surface of the housing in the width direction of the housing. a pair of protrusions extending to the housing, a pair of through holes each penetrating the protrusions in the width direction of the housing, and a pair of through holes respectively inserted into the through holes to secure the frame so that it is not separated from the housing. It may include fixing pins.

In addition, the lightweight beam frame may include a hollow bar-shaped body, and a pair of recesses provided on the distal upper and lower surfaces of the body, respectively, and recessed in the body and extending in the width direction of the body. .

In this case, the fixing pin inserted into the through hole can be accommodated in the recess.

In one embodiment, the diameter of the fixing pin may be larger than the gap between the inner surface of the housing and the outer surface of the body.

The frame structure according to exemplary embodiments of the present invention can significantly reduce the production and transportation costs of the frame by standardizing columns and beams.

In addition, by proposing a lightweight steel frame slide joint that can connect frames to each other with the simple act of inserting a fixing pin, a sturdy frame structure can be manufactured in a short period of time. In particular, since frames can be connected to each other without welding, the general public can easily manufacture frame structures for modular homes anywhere.

In addition, even when dismantling a manufactured modular house, the frames connected to the lightweight beam frame slide joint can be easily separated. Therefore, there is an advantage that the modular house can be dismantled and reinstalled.

Frame 30 may include columns 35 and beams 37. The pillar 35 refers to a frame installed in a direction perpendicular to the ground, and the beam 37 may refer to a frame connecting neighboring pillars 35 to each other. In other words, the frame 30 can be a pillar 35 or a beam 37 depending on the purpose. Therefore, hereinafter, except in cases where the characteristics of the column 35 and the beam 37 are different from each other, they will not be distinguished and will be collectively referred to as the frame 30.

The frame 30 includes steel or a steel alloy, and may be cut into a bar shape to have a preset length. In this way, standardizing the frame 30 to a certain length has the advantage of significantly reducing manufacturing and transportation costs.

Alternatively, the length or thickness of the column 35 and the beam 37 may be different from each other. For example, in order to withstand a higher load, the thickness of the column 35 may be manufactured to be thicker than the thickness of the beam 37, or in order to secure a larger indoor area, the length of the beam 37 may be adjusted to the thickness of the column 35. ) may be manufactured longer than the length. For example, column 35 may be 6 m or 3 m long and beam 37 may be 3 m or 1.5 m long.

In one embodiment, the frame 30 may be a square steel pipe, a circular steel pipe, an H beam, etc. The steel pipe refers to a pipe made of steel in the form of a hollow bar, and may be referred to as a square steel pipe or a circular steel pipe depending on its cross-sectional shape. Additionally, the H beam may be a pillar whose cross section has the shape of the English alphabet 'H'. The frame 30 may be made of any of square steel pipes, circular steel pipes, and H beams, but recesses 33 need to be formed at both ends of the frame 30, respectively. Additionally, the shape of the receiving portions 110, 120, and 130 of the lightweight beam frame slide joint 40 may vary depending on the cross-sectional shape of the frame 30. For convenience of explanation, the following will only describe the case where the frame 30 is a square steel pipe. However, due to this, the present invention is not limited to being applicable only to square steel pipes, and round steel pipes or H-beams can also be used as the frame 30, if necessary.

As shown in FIG. 4 , the frame 30 may include a hollow rod-shaped body 31 and recesses 33 formed on the upper and lower ends of the body 31, respectively. At this time, since the recesses 33 are formed at both ends of the body 31, at least four recesses 33 may be provided in one frame 30.

The cross section of the body 31 may be rectangular or square, and the length of each side may be appropriately changed as needed. For convenience of explanation, assume that the body 31 has a square cross-sectional shape. In this case, the body 31 may have a square cross-section where one side is the first length D1. For example, the first length D1 may be 100 mm to 150 mm. Additionally, the body 31 may be extended by a preset length and have a bar shape. For convenience of explanation, the direction in which the body 31 extends will be referred to as the ‘longitudinal direction’, and the direction perpendicular to the longitudinal direction will be referred to as the ‘width direction’.

The recess 33 may be a groove formed on one surface of the body 31 in the width direction. As shown in FIG. 4, recesses 33 may be provided on the top and bottom surfaces of the body 31, respectively. Alternatively, the recess 33 may be provided on each of the front and back surfaces of the body 31, the recess 33 may be provided on only one side of the body 31, or the recess 33 may be provided on the body 31. ), or the recess 33 may be provided on all surfaces of the body 31. If the recesses 33 are provided on all sides of the body 31, the recesses 33 may be connected to each other. In this way, if the recess 33 is provided on all sides of the body 31, there is no need to distinguish directions when inserting the body 31 into the receiving portions 110, 120, and 130, so the frame structure 10 The time required for assembly can be reduced.

The lightweight steel frame slide joint 40 is configured to easily connect the frames 30 without welding, and may have various shapes depending on the number of connected frames 30. For example, the first light beam frame slide joint 100 (see FIG. 4) can connect three frames 30, and the second light beam frame slide joint 200 (see FIG. 7) can connect four frames. (30) can be connected, the third light beam frame slide joint (300, see Figure 8) can fix one frame (30) to the ground, and the fourth light beam steel frame slide joint (400, see Figure 9). ) can connect two frames 30. In addition, although not shown, depending on the number of receiving parts, the lightweight beam frame slide joint 40 may connect five or more frames 30. Hereinafter, with reference to FIGS. 4 to 8, light beam steel frame slide joints 100, 200, and 300 of various shapes will be described in more detail.

First, the first lightweight beam frame slide joint 100 includes a first receiving part 110 extending in a first direction, and a second receiving part 120 extending in a second direction perpendicular to the first receiving part 110. ), and a third accommodating part 130 extending in a third direction perpendicular to the first and second accommodating parts 110 and 120. Figure 4 shows a first light beam frame slide joint 100 in which the first to third receiving parts 110, 120, and 130 are orthogonal to each other, but differently, the first to third receiving parts ( Any two of the receiving parts (110, 120, 130) may form an angle of 180°.

The first receiving portion 110 includes a housing 111 that accommodates the end of the frame 30 inside, a protrusion 113 protruding from the upper and lower surfaces of the housing 111, and a through hole penetrating the protrusion 113. (114), and may include a fixing pin 115 inserted into the through hole 114.

The housing 111 may be a square steel pipe with a square cross-section. The frame 30 may be inserted into one end of the housing 111, and the other end may be connected to the second accommodating part 120 and the third accommodating part 130. Accordingly, the length of one side of the inner surface of the housing 111 (second length, D2) may be greater than the length of one side of the body 31 (first length, D1).

The protrusion 113 protrudes from the outer surface of the housing 111 and may extend in the width direction of the housing 111. The protrusions 113 may be provided on the upper and lower surfaces of the housing 111, respectively. Alternatively, the protrusions 113 may be provided on the front and back surfaces of the housing 111, respectively. The through hole 114 may penetrate the protrusion 113 along the direction in which the protrusion 113 extends.

The fixing pin 115 can fix the body 31 inserted into the housing 111 by being coupled to the through hole 114. For example, the fixing pin 115 may be composed of a bolt 116 and a nut 117. In this case, the diameter (third length, D3) of the bolt 116 may be larger than the gap (D2-D1) between the inner surface of the housing 111 and the outer surface of the body 31. Therefore, the bolt 116 cannot be inserted into the through hole 114 when the protrusion 113 and the recess 33 are not aligned, and the positions of the protrusion 113 and the recess 33 are aligned. Only in this case can the bolt 116 be inserted into the through hole 114. For example, the third length may be 8 mm to 12 mm. A portion of the bolt 116 inserted into the through hole 114 is accommodated in the recess 33 formed in the body 31 and may restrict the movement of the body 31. Accordingly, the frame 30 can be firmly fixed to the first light beam frame slide joint 100.

Meanwhile, Figure 4 shows an example of a fixing pin 115 composed of a bolt 116 and a nut 117, but the present invention is not limited thereto, and is inserted into the through hole 114 to prevent the frame 30 from falling out. Any form is acceptable as long as it can be prevented.

The second and third accommodating parts 120 and 130 are substantially the same as or similar to the first accommodating part 110 except for the extending direction. Accordingly, overlapping descriptions of the second and third accommodating parts 120 and 130 will be omitted.

As described above, the first lightweight beam frame slide joint 100 is formed by simply inserting the frame 30 into the receiving portions 110, 120, and 130 and then inserting the fixing pin 115 into the through hole 114. The frames 30 can be connected to each other quickly, easily, and robustly. Therefore, even non-skilled people can easily manufacture the frame structure 10 for a modular house, and the time to assemble the frame structure 10 can be greatly shortened.

As shown in FIG. 7, the second light beam frame slide joint 200 has four receiving portions 210, 220, 230, and 240 extending in different directions, and connects the four frames 30. You can. At this time, the receiving portions 210, 220, 230, and 240 may be perpendicular to each other or may form an angle of 180°. Meanwhile, since the receiving portions 210, 220, 230, and 240 are substantially the same as the first receiving portion 110 of the first light beam frame slide joint 100 except for the extending direction, duplicate description thereof is provided. Decided to omit it.

As shown in FIG. 8, the third lightweight beam frame slide joint 300 includes a receiving portion 310 for accommodating the frame 30, and a fixing panel 320 for fixing the receiving portion 310 to the ground. may include. In particular, the third light beam frame slide joint 300 has only one receiving portion 310 and can firmly fix the frame 30 to the ground. That is, the third light beam frame slide joint 300 can be used to fix the pillar 35 to the ground.

The receiving portion 310 extends upward and perpendicular to the ground, and is substantially the same as or similar to the first receiving portion 110 of the first light beam frame slide joint 100. The fixing panel 320 is coupled to the lower part of the receiving portion 310 and may have a plate shape. The fixed panel 320 can be firmly fixed to the ground using anchor bolts (321), screws, etc. Accordingly, the pillar 35 can be firmly fixed to the ground.

Meanwhile, in Figure 3, a first light beam steel frame slide joint 100 connecting three frames 30, a second light beam steel frame slide joint 200 connecting four frames 30, and one Although the frame structure 10 is shown including a third light beam frame slide joint 300 that secures the frame 30 to the ground, the frame structure 10 may further include other types of light beam steel frame slide joints. You can. For example, the frame structure 10 includes a fourth light beam frame slide joint (not shown) connecting five frames 30, and a fifth light beam steel frame slide joint connecting six frames 30. (not shown), a sixth light beam frame slide joint (not shown) connecting the two frames 30, etc. may be further included. The fourth to sixth light beam frame slide joints are substantially the same as or similar to the first light beam frame slide joint 100 except that they have as many receiving portions as the number of frames 30 to be connected. Therefore, redundant explanation regarding this will be omitted.

As described above, the frame structure 10 according to the present invention can greatly reduce the production and transportation costs of the frame 30 by standardizing the columns 35 and beams 37. In addition, by proposing a lightweight steel frame slide joint 40 structure that can connect the frames 30 to each other just by inserting the fixing pin 115, a sturdy frame structure 10 can be manufactured in a short time. In particular, since the frames 30 can be connected to each other without welding, the general public can easily manufacture the frame structure 10 for a modular house anywhere.
