Field of technology

The present invention relates to a truss type deck plate formed by integrally attaching a reinforcement girder on a bottom substrate, and more particularly, to attach a bonding plate to a lower portion of the reinforcement girder in fixing the reinforcement girder on the bottom substrate. Improved non-weld joint deck, which is very aesthetically advantageous without any traces of welding at the bottom of the bottom substrate by bonding the bottom substrate and the bottom substrate together by physical and mechanical methods by using a joining protrusion and a coupling hole rather than the conventional welding method. Plates and methods of making the same.

Prior art

Generally, deck plate is a material for slab manufactured by processing metal plate such as galvanized steel sheet to form a structure without dismantling after concrete pouring as a substitute for existing formwork in building slab of building. In other words, when the slab is constructed using such deck plates, the construction and dismantling of the formwork can be omitted, thereby reducing the construction period and cost, and using the product produced at the factory to a certain level of quality. It has a number of advantages, such as to secure a bar, the recent trend is increasing the construction of slab structures using deck plates centered on high-rise steel frame buildings.

Various types of deck plates have been developed and used in the past, and in particular, recently, a truss girder for rigid reinforcement is integrated on a floor board having a substantially flat plate shape in view of reduction of slab thickness and structural performance. So-called truss-type deck plates made by laying them are widely used. 1 is a view showing the most representative type of the truss type deck plate as described above, the general configuration of the conventional truss type deck plate as shown in the drawing is the weight and construction of concrete poured on the top It comprises a bottom substrate (1) made of a metal plate material of a predetermined thickness to withstand the load, and a truss girder (2) fixedly fixed along the longitudinal direction on the top surface of the bottom substrate (1).

On the other hand, in the manufacture and production of the conventional truss-type deck plate as described above, the most common method of attaching and fixing the truss girder (2) to the upper surface of the bottom substrate (1) is by the spot welding (spot welding), which is a truss After mounting the girder 2 at a predetermined position of the bottom substrate 1, a large amount of current is placed in the state where electrodes are placed on the top of the foot 2 'of the truss girder 2 and the bottom of the bottom substrate 1, respectively. It was a way to allow the mutual welding by the electric resistance heat at the contact point by energizing the.

However, in the case of the conventional truss deck plate as described above, since the truss girder 2 is directly welded to the upper surface of the bottom substrate 1 in welding fixing of the bottom substrate 1 and the truss girder 2, the welding operation is performed. After this is completed, there is a problem that a welding trace occurs on the bottom of the bottom substrate. Therefore, the conventional deck plate as described above is difficult to use in places exposed to people's eyes because it is very poor in appearance to be used as a ceiling finishing material by itself, in this case, ceiling painting work after installation of the deck plate Or additional ceiling finishing work was required because of the additional cost and time.

In addition, as another method for solving the problems caused by the above traces of welding, there was a case in which the bottom surface of the bottom substrate was applied after the welding operation in the manufacturing step of the deck plate, but in the case of such a deck plate, the painting process is added. As a result, there was a problem that the unit price of the product increased, which was not a fundamental solution to the problem described above.

Therefore, the present invention has been made to solve the problems shown in the conventional welded fixed truss deck plate as described above, specifically, the present invention is directly fixed to the bottom substrate in fixing the reinforcement girder of the truss deck plate on the bottom substrate Unlike the existing method of welding the reinforcement girder, by attaching the bonding plate to the lower part of the reinforcement girder and joining the bonding plate and the bottom substrate together by the physical and mechanical method instead of the conventional welding method, The technical problem to be solved is to provide an improved non-welded truss deck plate and a method of manufacturing the same, which can not only prevent the deterioration due to coating or plating damage due to the absence of welding traces. Shall be.

In order to achieve the above technical problem, the non-welded junction deck plate provided by the present invention includes a bottom substrate provided with a predetermined size using a metal plate material; A reinforcement girder positioned on the bottom substrate and including at least one reinforcing bar to reinforce rigidity of the deck plate; And a coupling plate connected to the lower side of the reinforcement girder and simultaneously bonded to an upper surface of the bottom substrate, wherein one side of the coupling plate and the bottom substrate is formed with coupling holes drilled up and down, and the other side of the coupling protrusion. It is characterized by its basic configuration that is formed to protrude through the coupling hole.

In addition, the present invention provides a method for producing a deck plate of the above configuration, comprising the steps of (a) integrally attaching the coupling plate perforated with a coupling hole in the lower portion of the reinforcement girder; (b) arranging the reinforcement girder to which the coupling plate is attached at a position to be installed on the bottom substrate; (c) placing a concave mold provided with a concave groove on an upper part of the coupling hole of the coupling plate, placing a punch with a pressing surface protruding from the bottom of the bottom substrate, and pressing the bottom substrate with the punch to press the bottom substrate. Forming a coupling protrusion protruding to an upper portion of the coupling hole; Method for manufacturing a non-contact joint deck plate using a crimping projection and a rivet, including;

(a) integrally attaching the coupling plate to the lower portion of the reinforcement girder; (b) placing the reinforcing girder with the coupling plate attached to a predetermined position on the bottom substrate where the coupling hole is drilled; And (c) placing a concave mold having a concave groove below the coupling hole of the bottom substrate, placing a punch with a pressing surface protruding from the upper side of the coupling plate, and pressing the coupling plate with the punch to press the bottom. Forming a coupling protrusion protruding from the substrate below the coupling hole; It provides a method for producing a non-contact bonding deck plate using a crimping projection and a rivet comprising a.

As described above, in the present invention, when attaching the reinforcement girder to the upper portion of the bottom substrate, the foot portion of the reinforcement girder is compared to the existing deck plate that is directly fixed by spot welding on the upper surface of the bottom substrate. The coupling plate is integrally attached in advance (for example, by welding or the like), and the coupling plate is physically and mechanically formed by using the coupling protrusion formed by forming the plate itself rather than the conventional welding method and drilling the plate. The main structural features are distinguished from the prior art in that the reinforcement girder is fixedly installed by joining the bottom substrate by the method.

In addition, according to the characteristic reinforcement girder installation method of the present invention, since the reinforcement girder is not directly welded to the bottom substrate as in the prior art, the generation of welding traces on the bottom surface of the bottom substrate, which has been pointed out as an important disadvantage in the prior art And problems such as aesthetic defect or plating damage caused by this can be obtained at the source completely suppressed.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention as described above through the present invention in more detail.

Figure 2 is a view showing a preferred embodiment for a non-contact joint deck plate using a coupling hole and a coupling protrusion of the present invention, the deck plate according to the present invention as shown in the figure as a whole, the role of the base of the deck plate The truss-type deck plate known by integrally attaching the truss reinforcement girder 20 as a reinforcement member on the metal bottom substrate 10 to the object, the reinforcement girder 20 in such a known deck plate The lower portion of the coupling plate 30 is configured to be integrally attached, and the coupling plate 30 is integrally bonded to the bottom substrate 10 in an overlapping state up and down, so that the reinforcement girder 20 is the bottom substrate 10. Is configured to be fixed to the upper portion of the.

Here, referring to FIG. 3 showing a cross-sectional structure of the coupling portion, the coupling plate is bonded to the bottom substrate in more detail. As illustrated, the coupling hole 35 vertically penetrates the coupling plate 30. The perforated, the bottom substrate 10 can be seen that the coupling protrusion 15 is formed to pass through the coupling hole 35 of the coupling plate 30 to the corresponding position at the corresponding position. In addition, according to the illustrated embodiment, the upper portion of the coupling protrusion 15 protruding to the upper portion of the coupling hole 35 is the head portion 15 'is formed in a size larger than the size of the coupling hole 35. As a result, the coupling plate 30 is configured to be prevented from being separated from the coupling protrusion 15.

In the configuration of the present invention as described above, the bottom substrate 10 corresponds to a general deck plate substrate using a metal plate of a predetermined thickness so as to withstand the weight and construction load of the concrete placed on the top, This can be produced using a galvanized steel sheet commonly used in deck plates, a stainless steel sheet, a painted steel sheet painted with paint, or an aluminum plate. In addition, in the present invention, it is preferable that the bottom substrate 10 has a substantially flat plate shape according to the general truss deck plate type as in the embodiment shown in FIG. 2, which is a layer height after the deck plate is installed and installed. This is to minimize the rise of. (Of course, in the present invention, in addition to the flat form as shown, the bottom substrate may be sufficiently considered in some cases, such as repeating trapezoidal bone and acid or other forms, as in a traditional deck plate. It should not be excluded.)

The reinforcement girder 20 for rigidly reinforcing the bottom substrate is integrally installed on the bottom substrate 10. This reinforcement girder 20 corresponds to a kind of reinforcement to make up for the lack of rigidity of the floor substrate (especially flat floor substrate), as is well known, which is a horizontal reinforcing bar 21 for rigid reinforcement and It is common to have a shape that is roughly similar to a truss, including a lattice wire 25 symmetrically attached to both sides to support the horizontal reinforcing bar 21. In the art, such a reinforcement is generally called a truss girder.)

As described above, the present invention is a truss deck formed by laying a reinforcement girder 20 consisting of reinforcing bars or steel wires on the flat bottom substrate 10 of the deck plate has been developed and used in various forms in the past As the object of the plate, the only structural feature of the present invention for such a known truss deck plate is in a joining structure in which the reinforcement girder 20 is integrally fixed on the bottom substrate 10. .

Referring to the characteristic configuration of the present invention as described above in more detail as follows. As can be seen from the figure of Figure 2 in the non-contact fixed truss deck plate provided in the present invention in the foot (25 ') of the lattice wire 25 forming the reinforcement girder 20, the coupling plate 30 of a predetermined size It is attached integrally. This coupling plate 30 is configured to be attached to the ground horizontally, as shown, the size of the at least a lattice wire foot (25 ') rather than to be configured to a suitable length so as to project outward (length direction), According to the embodiment shown it can be seen that the coupling plate 30 is configured in the form of a strip long over the entire length of the deck plate.

As the material of the coupling plate 30, an iron plate (not necessarily to be rust prevented since it is to be embedded in the concrete later) can be used appropriately, and the reinforcement girder 20 and firmly by using a method such as welding To be combined. On the other hand, in the case of the attachment position of the coupling plate 30 can be attached to the bottom of the lattice wire 25 foot 25 'as shown in Figure 4 (a), of course, in Figure 4 (b) As illustrated, it may be configured to be attached to the top of the foot 25 '.

As described above, the reinforcement girder 20 to which the coupling plate 30 is integrally attached to the lower portion is firmly fixed on the bottom substrate 10 to function as a reinforcement body for the bottom substrate 10, in the present invention. The coupling between the reinforcement girder 20 and the bottom substrate 10 is made through the above-described coupling plate 30 to represent the most important features of the present invention, which are distinguished from the prior art.

This will be described in more detail with reference to the illustrated embodiment as follows. 2 and 3, in the present invention, the coupling plate 30 is integrally attached to the lower portion of the reinforcement girder 20, and the coupling plate 30 is disposed to overlap the bottom substrate 10 in the vertical direction. The reinforcement girder 20 is installed by being integrally fixed to the bottom substrate. Here, according to the embodiment shown in the coupling plate 30 is formed through the coupling hole 35 in the vertical direction, the coupling substrate 15 is protruded in the bottom substrate 10, the above-mentioned coupling hole 35 By being installed so as to pass up and down, the coupling plate 30 is configured to be bonded to the bottom substrate 10 by fitting between the coupling protrusion 15 and the coupling hole 35. In addition, as shown, the upper end of the coupling protrusion 15 is formed by the head portion 15 'is prevented from falling out of the coupling hole 35 is configured to enable a firm fixing. (On the other hand, in the illustrated embodiment, the coupling hole 35 is formed in the coupling plate 30 and the bottom substrate 10 is illustrated as a configuration in which the coupling protrusion 15 is formed. It is also possible to make a configuration that punctures and forms a coupling protrusion on the coupling plate)

As described above, according to the characteristic configuration provided in the present invention, in the fixed installation of the reinforcement girder 20 to the bottom substrate 10, attaching the coupling plate 30 separately to the lower portion of the reinforcement girder and the coupling plate 30 ) To the bottom substrate 10 to install the reinforcement girder 20, in the bonding of the coupling plate and the bottom substrate, the coupling hole is formed in one material, the coupling protrusion is formed in the other material and the coupling projection and the coupling hole between According to the characteristic reinforcement girder installation method of the present invention, the reinforcement girder is not directly welded to the bottom substrate as in the prior art, so it is pointed out as an important disadvantage in the prior art. The problems such as the generation of welding traces on the bottom surface of the bottom substrate and the resulting aesthetic defect or plating damage can be completely suppressed. Will be.

On the other hand, in connection with the specific bonding of the present invention, in connecting the coupling plate 30 to the bottom of the reinforcement girder 20 in general, the welding method may be preferably used, but in such a case also Since the coupling plate 30 and the bottom substrate 10 are fixed by a physical fitting method by forming a crimping protrusion rather than a welding method, there is no fear that the welding traces below the coupling plate will be exposed to an external line of sight. That is, after fixing the coupling plate 30 to the bottom substrate 10, only the outline of the coupling protrusion is visible at the bottom of the bottom substrate and the welding traces of the bottom of the coupling plate 30 overlap with the bottom substrate. By not appearing by the load, it is possible to make the joint between the reinforcement girder and the floor board without visually messy feeling.

On the other hand, in the practice of the present invention, although the general galvanized steel sheet may be used as the bottom substrate 10, a colored metal plate or various functional paints (for example, far-infrared ray-emitting paints or electromagnetic waves) coated on the surface to prevent aesthetics and corrosion. In the case of using a coated steel sheet coated with a barrier paint), the characteristics of the present invention are well highlighted, and thus an excellent effect can be obtained. That is, in the case of general deck plates in which the reinforcement girder is fixed on the bottom substrate by the conventional welding method, if you want to use the coated steel sheet, the coating of the lower part is peeled off or altered due to the heat of welding, so it is not very aesthetically pleasing as well as corrosion and function. There was a problem that there is a risk of degradation. However, in the case of the deck plate to which the present invention is applied as described above, the bonding plate and the bottom substrate are fixed in a non-contact manner by a physical method, thereby exhibiting a very clean and beautiful appearance as a whole without fear of coating damage shown in the prior art and deteriorating function. There is an advantage that can be prevented.

Hereinafter, a method for manufacturing a non-contact bonding deck plate of the present invention as described above will be described with reference to the accompanying drawings.

Method for producing a non-welded bonded truss deck plate provided by the present invention as a whole comprises the steps of (a) integrally attaching the coupling plate perforated coupling holes in the lower portion of the reinforcement girder; (b) disposing the reinforcement girder to which the coupling plate is attached at a position to be installed on the bottom substrate; And (c) placing a concave mold provided with a concave groove on an upper part of the coupling hole of the coupling plate, placing a punch with a pressing surface protruding from the bottom of the bottom substrate, and pressing the bottom substrate with the punch to press the bottom. Forming a coupling protrusion protruding to an upper portion of the coupling hole of the substrate; Including, or

Alternatively, (a) integrally attaching the coupling plate to the lower portion of the reinforcement girder; (b) placing the reinforcement girder with the coupling plate attached to a predetermined position on the bottom substrate on which the coupling hole is drilled; And (c) placing a concave mold having a concave groove below the coupling hole of the bottom substrate, placing a punch with a pressing surface protruding from the upper side of the coupling plate, and pressing the coupling plate with the punch to press the bottom. Forming a coupling protrusion protruding from the substrate below the coupling hole; It may be made, including.

The most characteristic process in the manufacture of the deck plate of the present invention as described above is the process of joining the bonding plate and the bottom substrate, that is, the bonding protrusion provided on the other side of the plate material by protruding the engaging projection on one side of the bonding plate or the bottom substrate It can be said to be in the process of integrating the bonding plate and the bottom substrate (step (c) in each manufacturing process described above) by being inserted into a ball, which will be described in more detail with reference to FIG. . (On the other hand, Figure 6 illustrates that the coupling holes are formed in the coupling plate and the coupling protrusions are formed in the bottom substrate. However, in the case of forming the coupling plate, the coupling method is essentially the same.)

FIG. 6 is a view schematically illustrating a process of joining a coupling plate and a bottom substrate by a coupling hole and a coupling protrusion in manufacturing a truss deck plate according to the present invention. As shown in FIG. In implementing the bonding method, first, a reinforcement girder (not shown) in which the coupling plate 30 is integrally attached to the bottom is disposed at a predetermined position on the bottom substrate 10, and then the coupling hole of the coupling plate 30 ( 35) the concave mold 200 having the concave groove 220 is disposed on the upper portion, and the punch 100 having the pressing surface protruding is disposed below the bottom substrate 100. (At this time, the size of the groove 220 provided in the concave mold 200 to have a size at least larger than the diameter of the coupling hole 35)

After placing the mold and the punch on the upper and lower portions of the coupling plate and the bottom substrate as described above, when the punch 100 is operated and pressed to the concave mold 200, the punch 100 is the bottom substrate ( 10, the bottom substrate material is pushed into the groove 220 of the concave mold 200 through the coupling plate 30 by pushing. According to the crimping process, the coupling protrusion 15 protrudes by plastic deformation of the bottom substrate 10, and the button is convex at the distal end of the coupling protrusion 15 by the shape of the groove 220 of the concave mold 200. As the head portion 15 'is shaped into a shape, a coupling portion structure as shown in FIG. 3 is formed. As a result, the coupling plate 30 attached to the bottom of the reinforcement girder is firmly coupled to the bottom substrate 10. The reinforcement girder will be installed.

On the other hand, Figure 5 is a plan view showing a configuration for various modified embodiments of the present invention, the present invention can be modified in various forms in addition to the form shown in FIG. That is, as in the embodiment shown in Fig. 5 (a) it is also possible to attach one piece for each foot individually, in addition to the longitudinal direction of the reinforcement girder 20 as shown in Fig. 5 (b) A plurality of foot 25 is formed by forming the coupling plate 30 in parallel with respect to, or by forming the coupling plate 30 in the vertical direction with respect to the longitudinal direction of the reinforcement girder 20 as shown in FIG. It is also possible to interconnect the ')' s.

In addition, the present invention can be applied to the reinforcement girder of the truss-shaped reinforcement girder as illustrated in the form of the reinforcement girder as well as other reinforcement girders that are conventionally used for the reinforcement of the deck plate. Those skilled in the art will readily understand.
