Description

Structure to connect roof of sectional building

The present invention relates to a roof fastening structure of a prefabricated building, and more particularly, the length of the roof body is configured to be long so that the roof body can be smoothly supported without sliding limitations, no matter how long the extension length of the roof body according to the external air temperature is, of course. This is to keep the roof body's resistance to wind pressure at all times regardless of the surrounding conditions.

As is well known, when constructing a prefabricated building, the roof is structured with a focus on several elements that can greatly insulate, absorb, leak, and support. The material for improving insulation and sound absorption is polyester wool or inorganic. The glass wool is mainly used as insulation, but the contraction force is large and its own supporting strength is very weak.

Therefore, in order to reinforce the holding force of the plate having a heat insulating property and sound absorption (hereinafter referred to as a sound absorbing plate), a plate formed of a metal plate is applied to the upper surface of the plate, and the unit plate formed of the metal plate and unit forming plate connection and At the same time as the connection between the molded plate and the sound absorbing plate material is made to be bound, roof fasteners are required to prevent leakage to the connection portion of each unit formed plate.

1 is a cross-sectional view showing a roof fastening structure of a general prefabricated building, and a sandwich panel formed by attaching a support plate body 11 and a protective plate 12 to upper and lower surfaces of a sound absorbing plate member 10 having heat insulation and sound absorption, respectively. On top of the sandwich panel, a forming plate 20 made of a metal plate is disposed, and another forming plate 20 adjacent to an arbitrary forming plate 20 by the roof fastener 30, the forming plate 20 and the sandwich panel. (10) (11) (12) are fixed to each other.

At this time, the general roof fastener 30 used is a bearing plate 31 which is placed on the protection plate 12 in a large area, and is mounted on the bearing plate 31 in a state of being bent in an "L" shape to the bolt 13. The clip body 32 fixed to the protective plate 12, the sound absorbing plate material 10, the support plate body 11 at one time, and the lower portion is fitted into the sliding groove 32a formed in the middle portion of the clip body 32 in the transverse direction. It is configured to slide according to the expansion and contraction of the roof body 20 according to the outside air and the upper portion is made of a sliding clip 33 configured to be curled and finished with the ends of the corresponding roof body 20 in a state bent in one direction. In order to prevent leakage when the upper portion of the sliding clip 33 and the end of each forming plate 20 are curled together, the packing 14 may be disposed between the end of the outermost forming plate 20 and the upper portion of the sliding clip 33. ) Is inserted.

Figure 2 is a roof fastener (100) filed by the applicant as a utility model registration application No. 2008-7385 to compensate for the disadvantages of such a general roof fastener, the cut portion 111 of the "∩" shape on both sides of the middle The portions connecting each of the cutouts 111 in a symmetrically formed state are bent at right angles as a whole to form a support surface 113 having a relatively large area on one side of the bent portion and at the same time on each other side. The support surface 112 of the "∩" shape on the plane which was located inside the (111) is located, the sliding groove 114 is formed in the transverse direction above the cutout portion 111, the support surface 112 (113) A plurality of fastening holes 115 are formed in the wide support surface 113 of the clip body 110 fixed to the sound absorbing plate member 10 by bolts 13 through the fastening holes 115; And the lower part is inserted into the sliding groove 114 of the clip body 110 and configured to slide according to the expansion and contraction of the forming plate 20 according to the outside air, and the upper part of the forming plate 20 corresponding to the bent in one direction. It is composed of a sliding clip 120 is configured to be curled with the end of the finish.

However, as the size of the prefabricated building increases, the length of the roof body also increases, and when the length of the roof body increases, the degree of expansion of the roof body according to the outside air also increases if the temperature difference is severe depending on the season. The fastener or roof fastener according to Utility Model Registration No. 2008-7385 is designed to slide in the sliding groove according to the expansion and contraction of the roof body by sliding the clip into the sliding groove of the clip body. There is a limit to play.

Therefore, in order to overcome this sliding limit, the length of the sliding groove is inevitably increased by increasing the clip body, and when the clip body is lengthened, the tensile strength and durability are weakened inversely to this, so that the clip body is secured to secure tensile strength and durability. Inevitably, the manufacturing cost of the roof fasteners had to be greatly increased because of the thick construction, and no matter how long the clip body was constructed, it was impossible to slide more than a certain length.

In addition, since the sliding clip is fitted into the sliding groove of the clip body, when the wind pressure is applied to the roof body fixed to the sliding clip, such a pressure is applied to the upper portion of the sliding groove of the clip body, and the clip body is easily broken, and the sliding There was also a problem that the clip is easily separated from the clip body, and the clip body is usually manufactured by the press method, and its size and shape are standardized, whereas the size and shape of the roof body of the prefabricated building varies depending on the site. It was also difficult to respond easily.

That is, it is preferable that the size of the clip body is determined according to the size of the roof body, but the size of the clip body is standardized, so it is difficult to fit in all site conditions.

On the other hand, in the case of a large-scale prefabricated building it is expensive to construct a roof using a sandwich panel in this case, the support plate body 201 is laid in this case, the metal molded plate 203 in a state of laying the insulation 202 thereon ) To fix the arbitrary forming plate 203 and other forming plate 203, forming plate 203, heat insulating material 202, support plate body 201 at a time through the roof fastener, Unlike the roof structure, there is a difference in applying the supporting plate body 201, the heat insulating material 202, and the forming plate 203 individually without using a sandwich panel that is manufactured, thereby reducing the manufacturing cost. .

In addition, such a method is called a double skin method because it interposes a heat insulating material between the lower support plate body and the upper molded plate.

Roof fasteners are required even when the double skin method is applied, and FIG. 3 illustrates an example in which the general roof fastener 30 is applied to the double skin method.

Since the double skin method is applied to a large-scale prefabricated building, the roof body is often very long. Therefore, as a roof fastener of a prefabricated building according to the double skin method, a general roof fastener or a utility model registration application No. 2008 When the roof fastener according to -7385 is applied, when a general roof fastener or a roof fastener according to Utility Model Registration No. 2008-7385 is applied to a long roof when constructing a general prefabricated building as described above, There are several same disadvantages.

In consideration of this, when the roof body is composed of a sandwich panel or the roof body is applied by applying the double skin method, the length of the roof body is configured to be long so that no matter how long the extension length of the roof body according to the external temperature is sliding It is to provide a roof fastening structure of a prefabricated structure to support the roof body smoothly without limits and to maintain the roof body's resistance to wind pressure at all times regardless of external conditions.

In order to solve this problem, the present invention is configured to open the sliding groove of the "ㅗ" shape on the front in the upper center and the front and rear directions in the center of the upper portion of the clip body to support the ground, the sliding clip directly fixed to the roof clip The lower part is configured to be longer than the length of the body, and the lower part is formed in the shape of "ㅗ" so that this part is inserted into the sliding groove so that it is slid in the front and rear direction so as not to be rebounded upward.

The present invention is configured to have a longer length of the sliding clip than the length of the clip body constituting the roof fastener, and the "ㅗ" shaped lower end of the sliding clip is slidably fitted into the "ㅗ" shaped sliding groove of the clip body. Since the length of the roof body is long, the length of the expansion and contraction of the roof body according to the outside air can slide smoothly while the sliding clip is supported on the clip body, thereby overcoming the sliding limit. Even if you do not enlarge or thicken the thickness of the clip body will be able to always maintain a constant resistance to the wind pressure of the roof body.

In addition, the length of the sliding clip has the advantage that the clip body can be selected to a suitable length according to the length of the roof body and the degree of expansion according to the change of the outside air in a fixed state, and the extrusion of the clip body in aluminum to the site conditions at that time It can be cut and used accordingly so that any site conditions can be responded accordingly.

In addition, when applying the support bar when applying the double skin method, the roof fastener according to the present invention can be applied regardless of the shape of the support plate, and the roof fastener is interposed between the support plate and the roof fastener. Even though the heat is conducted along the sphere, the heat can be blocked by the insulation bar to prevent heat from being transferred to the room.

Hereinafter, the present invention will be described in detail with reference to the presented embodiments and the accompanying drawings.

4 is a perspective view of the roof fastener according to the present invention, Figure 5 is a cross-sectional view of the roof fastening structure of the prefabricated building according to the present invention, Figure 6 is a cross-sectional view when the support bar is applied when the roof fastening of the prefabricated building according to the present invention, 7 is a cross-sectional view according to another embodiment when the support bar is applied when the roof fastening of the prefabricated building according to the present invention, Figure 8 is a case when the roof fastener according to the present invention is applied to a general prefabricated building using a sandwich panel It is a cross section.

As shown, the present invention is a heat insulating material 202 on the support plate body 201 in the state in which the roof fastener 210 is standing and fixed on the roof plate or the support plate body 201 of a general prefabricated building using a sandwich panel. Is applied, and the forming plate 203 is laid on the heat insulating material 202, and the forming plate 203 is applied to the double skin method in which each forming plate 203 is fixed to each other by the roof fastener 210.

The present invention overcomes the sliding limit of the sliding clip 215 as well as to increase the tensile stress to implement a more stable roof body, for this purpose the clip body 211 constituting the roof fastener 210 is in front " The sliding groove 212 of the "ㅗ" shape on the front to form a Y "shape is configured in a shape that is open in the upward and forward directions, the sliding clip 215 is configured longer than the full length of the clip body 211 The lower portion is formed in the shape of "형" so that this part is inserted into the sliding groove 212 is made to slide in the front and rear direction so as not to rebound in the upper direction.

At this time, when the sliding clip 215 is inserted into the clip body 211, the stopper 216 is located at the rear and rear of the sliding clip 215 so that the sliding clip 215 does not fall out from the clip body 211. Each of the stopper 216 may be formed by bending the front and rear surfaces of the sliding clip 215, or may form an embossing to protrude in one direction through a punch. The front and rear surfaces of 215 are cut out and constructed as an example.

Of course, the sliding clip 215 and the clip body 211 may be separately stored or transported in a state in which the stopper 216 is not configured in the sliding clip 215, and may be assembled with each other in the field. Even if 216 is not configured, it is obvious that the sliding action does not interfere at all.

In addition, when the roof fastener 210 is installed on the support plate body 201 and fixed thereto, the support plate body 201 and the roof fastener 210 may be prevented from being conducted through the roof fastener 210. The insulation bar 220 is interposed.

Reference numeral 217 in the drawing denotes a packing for preventing leakage from occurring between the molded plates 203 by being fitted inside the sliding clip 215.

When the roof fastener according to the present invention configured as described above is applied to the double skin method by way of example as follows.

First, the roof fastener 210 is erected and fixed in a state with an insulating bar 220 interposed on the supporting plate body 201, and the insulating material 202 is laid thereon, and the molding plate 203 is placed on the insulating material 202. It is laid, and fixed to any other forming plate 203 adjacent to the forming plate 203 through the roof fastener 210, the end of one side forming plate 203 is below the upper end of the sliding clip 215 Positioning, the end of the other side forming plate 203 is placed in the state above the upper end of the sliding clip 205 through the packing 217 is curled and fixed at once, each forming plate 203 can be fixed to each other Of course, the support plate body 201, the heat insulating material 202, the molding plate 203 by the roof fastener 210 can be fixed at one time.

In addition, when the forming plate 203 is stretched and contracted according to the outside air while the forming plates 203 of both sides are fixed by the roof fastener 210 as described above, the sliding clip 215 is fixed to the forming plate 203. ) Also has to move in the stretch direction of the forming plate 203, the size of the prefabricated building is large, the length of the forming plate 203 forming the roof body becomes long, the degree of expansion of the forming plate 203 according to the outside air is also very large As a result, the sliding stroke of the sliding clip 215 is also inevitably increased, and as the stroke increases, the tensile stress of the clip body decreases, thereby reducing the resistance to wind pressure of the roof body.

In order to solve this problem, in the present invention, the sliding groove 212 of the clip body 211 is opened in the front and rear direction, and the length of the sliding clip 215 fitted therein is configured to be at least longer than the clip body 211, and the roof The length of the sieve is configured to increase the degree of expansion and contraction according to the outside air, no matter how long the sliding length of the sliding clip 215, the sliding clip 215 according to the present invention is firmly supported without being separated from the clip body 211 Will be able to slide smoothly along the sliding groove 212 in the state. That is, there is no limit to the sliding length of the sliding clip 215 without any structural change.

In addition, the sliding groove 212 formed in the clip body 211 is formed in the form of a "ㅗ" to exert a uniform left and right stress on the sliding clip 215 body corresponding to the tensile force, such as wind pressure or the like roof fastener or Compared to the roof fastener according to Utility Model Registration No. 2008-7385, which the applicant has filed, the present invention not only can increase the tensile stress but also has the advantage of always exerting a constant tensile stress regardless of the length of the roof body.

That is, in the case of a general roof fastener or a roof fastener according to the Utility Model Registration Application No. 2008-7385 filed by the present applicant, a sliding clip having a shorter length than a sliding groove is fitted into the sliding groove of the clip body, so that the sliding stroke is a sliding groove. Since the length of the roof body is increased and the degree of expansion according to the outside air is increased in proportion to the difference between the sliding clip and the sliding clip, the sliding groove may be configured long and the thickness may be made thick while increasing the size of the clip body. There is no choice but to increase the manufacturing cost, and even in this way there is no limit to the sliding of course there is a limit to maintain a constant tensile stress, while the roof fastener 210 according to the present invention is the clip body 211 of Sliding grooves to a minimum size in the clip body 211 without changing the size and thickness ( 212) and by sliding the sliding clip into the sliding groove 212 to be able to slide without a sliding limit can perform a smooth sliding operation regardless of the length of the roof body as well as resistance to the wind pressure of the roof body You can always keep it constant.

In addition, the length of the clip body 211 is fixed and the length of the sliding clip 215 can be configured according to the length of the forming plate 203, 20 having various lengths according to the site and the degree of expansion according to the construction of Convenience can be achieved, and because the use of aluminum extrusion molding as the clip body 211 is to control the shape and length of the molding plate at the lowest cost and effort to respond to any site conditions accordingly.

On the other hand, when the double skin method is applied, as shown in FIG. 5, when the shapes of the support plate body 201 and the forming plate 203 are the same, when the support plate body 201 and the forming plate 203 are crossed by 1/2, the center is precisely aligned. Although it is possible to perform the roof construction, the work of aligning the center of the forming plate 203 to the supporting plate body 201 in this way is very cumbersome, and the shape of the supporting plate body 201 and the forming plate 203 as shown in FIG. In this other case, a problem arises in which the center cannot be aligned.
