Description

Technology Field

[0001] The present invention relates to a slab panel formwork for the construction of a concrete slab of a building, and further relates to a concrete slab panel formwork assembly for construction that facilitates the installation and dismantling of the slab panel formwork assembly by ensuring a firm fixation of the connection portion through the fastening of a fixing piece having an inner surface that fits with the slab beam while a beam connector is mounted on the connection portion between the slab beam and the top of the support, while configuring the beam connector and the filler panel to be separable. Background Technology

[0003] Generally, modern construction formwork consists mainly of an assembly of panels made of metal materials such as iron or aluminum. In this case, the slab formwork forms a supporting floor surface for concrete pouring by continuously arranging rectangular unit slab panels on a single plane between supports erected vertically from the floor and beams supported at the top of the wall formwork.

[0004] When the installation of such slab formwork is completed and concrete is poured into the formwork and cured, the formwork is dismantled. However, in most buildings, the height between the floor and the ceiling (floor height) far exceeds the height of the worker. Therefore, to dismantle the slab panels, the worker must use a ladder to separate the connected and assembled panels. During this process, the separated slab panels fall to the floor due to their own weight, which inevitably leads to damage to the metal panels and the risk of safety accidents. Furthermore, the noise and dust generated during the collision with the floor surface have acted as factors that worsen the environment of the construction site and its surroundings.

[0005] Considering the aforementioned problems arising from the formwork construction methods applied in existing building construction, Registered Patent No. 10-2041392 discloses a slab construction method known as the "drop construction method," in which, when dismantling the slab formwork, the slab panel is supported at a height lowered so that the worker does not fall straight from the ceiling to the floor but does not need to use a ladder, thereby allowing the worker to directly lift the panel to the floor. Since the application of this patented method to construction sites, the use of this method in the construction of high-rise buildings, including apartments, has been continuously expanding.

[0006] Meanwhile, FIGS. 1 to 4 show a slab panel drop device used in a drop construction method including the above-mentioned registered patent No. 10-2041392, FIG. 1 is a perspective view showing the assembled state of a slab panel formwork, FIG. 2 is a front view of FIG. 1, FIG. 3 is an exploded perspective view of the connection part of the slab beam, prop head, and support, and FIG. 4 is a cross-sectional view showing the state in which the slab panel assembly is separated from the prop head and seated on the stopper of the support.

[0007] As shown in FIGS. 1 and 2, wall panels (WP) for forming side walls are connected and assembled along the outer edge of the floor, and a soffit length (SL) is placed on top of it. A slab beam (40) in which a slab panel (SP) is supported between the soffit lengths (SL) on the top of both side walls is connected in a straight line through a fixing piece (30) and a fixing pin (P) centered on a prop head (21) attached to the top of a support (20) erected from the floor. Meanwhile, both ends of the slab beam (40) are connected through a beam fixing bracket (46) in which one end is connected to a corner bracket (45) mounted on the soffit length (SL) via a pin (P) and the other end is fixed by being caught on a pin (P2) that is fastened to the slab beam (40). Additionally, the soffit length (SL) and the adjacent slab panel (SP) are connected to each other through a connecting pin.

[0008] Meanwhile, slab panels (SP) are filled and supported between multiple rows of slab beams (40) that are supported parallel to each other between the above-mentioned soffit lengths (SL). When a pin is fastened while aligning the pin hole formed on the slab panel (SP) joining surface on the side of the slab beam (40) with the pin hole formed on the side of the slab panel (SP), the upper surface of the slab beam (40) and the upper surface of the slab panel (SP) form the same plane as shown in FIG. 1, thereby forming a support plane for the lower surface of the slab wall to be poured later.

[0009] And the two wings of the beam support guide (10), which is slidably mounted on the outer surface of the support (20), are installed so that the fixing piece (P) passing through the slab beam (40) and the fixing piece (30) passes through in common.

[0010] The beam support guide (10) is formed by combining a pair of guide bodies (10A, 10B) formed symmetrically with each other, wherein each guide body (10A, 10B) comprises a mounting body part (11) mounted on the outer circumference of a support (20), a vertical connecting part (12) extending upward from the mounting body part (11), a horizontal extension part (13) extending horizontally outward from the upper end of the vertical connecting part, a variable wing (14) capable of sliding along the upper surface of the horizontal extension part and having an outer end bent upward, and a wing guide (15) that guides the variable wing without it deviating from the horizontal extension part (13).

[0011] The above pair of guide bodies (10A, 10B) are structured such that one side of the mounting body part (11) is hinge-connected and the other side is mounted to the outer circumference of the support (20) by fastening a fastening piece (16). At this time, a reinforcing member (18) that is elastically installed by a spring (S) is mounted on the reinforcing member seating part (17) formed between the mounting body part (11) and the outer circumference of the support (20), thereby maintaining a state in which the support (20) and the beam support guide (10) are elastically in contact. The reinforcing member (18) is configured to include a friction member head (18a) that makes frictional contact with the outer circumference of the support by the elastic force of the spring (S), and a fixed rod (18b) that extends from the friction member head and is located in the reinforcing member seating part (17) with a spring interposed therein.

[0012] Typically, the connection and fixation of the slab beam and the prop head are achieved by a pair of fixing pieces that are commonly fastened to the prop head, the slab beam, and the beam support guide. That is, in the invention, regardless of the position where the handle pin (41) is formed on the existing slab beam (40), the mounting of the beam support guide is made smooth by adjusting the length of the variable wing (14) of the beam support guide (10).

[0013] In the slab panel formwork assembly of the above structure, after the curing of the slab concrete is completed, the slab beam (40) separated from the prop head (21) and the slab panel (SP) supported thereon are supported and are configured to gradually descend along the support (20).

[0014] When dismantling a slab panel assembly using this drop method, first, the pin (P1) fastened to the beam fixing bracket (46) connecting the soffit length (SP) of FIG. 2 and the end of the slab beam (40) is removed to release the connection between the soffit length (SP) and the slab beam (40), and at the same time, the connecting pin fastened between the soffit length (SL) and the slab panel (SP) is removed. Subsequently, a transition from the state of FIG. 2 to the state shown in FIG. 4 is made.

[0015] To do this, the slab beam (40) is separated from the prop head (21). The separation between the two members is initiated by removing the pin (P) inserted into the central pin hole of the fixing piece (30) and striking the side of the stop key (22) to move the large diameter portion (22a) toward the support (20) so that the locking is released.

[0016] Accordingly, only the unlocked stop key (22) descends and is positioned on the mounting body (11) of the beam support guide (10), while the remaining parts remain unchanged from their original positions. This is because the surface of the slab beam assembly, in which the slab panel and the slab beam are connected, maintains an adhesive state with the cured slab concrete.

[0017] Accordingly, in order to separate the slab panel assembly from the bonding surface with the slab concrete, the hook piece formed at the tip of the tool for dismantling the slab panel assembly is hooked to the pin (P) fastened to the pin hole of the fixing piece (30), and the support piece extended behind the hook piece is brought into contact with the bottom surface of the prop head. Then, by operating the handle rod using the lever principle, the slab panel assembly is separated from the bonding surface with the slab concrete, and the slab panel assembly begins to descend along the support (20) by its own weight.

[0018] As shown in FIG. 4, the descent of such a slab panel assembly is gradually lowered without a sudden drop by means of frictional force applied from a reinforcing member (18) that elastically contacts the outer surface of the support (20) while the slab beam (40) is supported by a fixing piece (30) and a beam guide (10), and is stopped upon contact with such a stopper (23).

[0019] However, in the slab panel drop construction method using the above-mentioned slab formwork assembly, the structure is such that the fixing piece (20), which connects the slab beams (20) to each other and allows the load of the slab beams (20) to be supported by the support (20), is seated within a seating groove area corresponding to a portion of the upper and lower width of the slab beams (20). Therefore, it has been pointed out that there is a problem in that there are limitations in maintaining a solid fixed state through close contact between surfaces over a wide area with the slab beams (20).

[0020] In addition, in the above-mentioned slab formwork assembly, the soffit length and the outer end of the slab beam are connected by a beam fixing bracket to support these two members. Consequently, during the assembly and disassembly of the slab panel assembly, the insertion or removal of connecting pins is required to connect and disconnect the beam fixing bracket, which acts as a factor that delays the assembly and disassembly of the slab panel assembly.

[0021] In addition, it is pointed out that in the aforementioned slab formwork assembly, since the connection work of the slab beams is carried out in the air rather than on the floor, it is very difficult for a worker to stand on a scaffolding and lift and connect the heavy slab beams and prop heads, and there is a high risk of safety accidents. The problem to be solved

[0022] The present invention was conceived in consideration of the problems of the aforementioned prior art, and the primary objective of the invention is to provide a concrete slab formwork assembly for construction configured such that a fixing piece, which connects two slab beams to be connected while supported by a support, has a width approximately equal to that of the slab beam and the inner surface of the connection aligns with the outer surface of the slab beam, thereby expanding the connection area and maintaining high connection strength through tight contact at the connection site.

[0023] Another objective of the present invention is to provide a concrete slab formwork assembly for construction that facilitates the installation of the slab formwork by connecting the slab beams by simply fastening a fixing piece to the slab beam connection part with a beam connector configured to be detachable from the filler panel on the floor rather than in the air, and by lifting the connected slab beams to a predetermined position between soffit lengths to perform subsequent slab panel assembly work.

[0024] Another objective of the present invention is to provide a concrete slab formwork assembly for construction that allows the slab panels supported on the slab beam to be fixedly supported by panel brackets mounted on the slab beam, thereby enabling the installation of the slab panel assembly without fixing the soffit length and the slab beam with a fixing bracket. means of solving the problem

[0026] The above and other objectives of the present invention are achieved by a concrete slab formwork assembly for construction comprising: a slab beam connector in which at least two slab beams are connected in a straight line and both ends are positioned adjacent to the top of a wall panel; a support erected on the floor to support the connection portion of the slab beam; a beam connector positioned on the top of the connection portion of the slab beam and the support to connect the slab beam and the support; a filler panel equipped with a support inserted into a support insertion hole formed on the upper surface of the beam connector; a pair of mating fixing pieces that are closely attached to the front and rear plates of the beam connector and the front and rear surfaces of the slab beam connection portion to enable the connection of the slab beam through pin fastening; a slab panel arranged planarly on the slab beam while forming the same plane as the upper surface of the filler panel; and a panel bracket mounted on each slab beam of the slab beam connector to fix the slab panel.

[0027] All constituent members of the concrete slab formwork assembly for construction according to the present invention are made of aluminum, and exceptionally, some may be made of metal or polymer materials other than aluminum.

[0028] The above slab beam is a straight beam having a hollow rail or an uppercase "I" shaped cross-section, and consists of a vertical, narrow hollow body section after passing through a tapered section where the width decreases sharply from a relatively wide upper and lower planar section. The above-mentioned mating fixing piece is seated in surface contact with the front and rear surfaces of the connection section of the slab beam having such a cross-section.

[0029] Next, the beam connector has front and rear plates that are wider at the top and narrower at the bottom, extending downward in parallel with a gap narrower than the width of the top surface, below the top surface of a square plane in which a support insertion hole is formed in the center, and a connecting rod equipped with a stopper hook extends from the inner center, passing between the front and rear plates.

[0030] The filler panel is coupled to the beam connector by inserting a support formed on its bottom surface into a support insertion hole on the top surface of the beam connector, wherein the bottom surface of the filler panel makes surface contact with the top surface of the beam connector. This filler panel has the same height as the slab panel, and pin holes are formed on its four sides for connection with adjacent slab panels. It is preferable that the support and the support insertion hole be configured as polygons, including squares, rather than circles, so that the fixed state of the coupled filler panel can be maintained.

[0031] In the present invention, the filler panel is formed to be separable rather than integrally with the beam connector. The first reason for this is to make it easier to lift the slab beam connector by reducing the weight of the slab beam connector, so that the slab beam connector can be obtained with only the beam connector and the mating fixing piece without the filter panel.

[0032] Secondly, when the width (or length) of the slab (floor or ceiling) to be constructed cannot be covered by slab panels of standardized dimensions, it is necessary to manufacture slab panels of dimensions suitable for the construction site. In this invention, the width of the filler panel can be manufactured according to the situation, so it is more economical compared to newly manufacturing non-standard slab panels.

[0033] Next, the above-mentioned mating fixing piece is a long hollow aluminum plate having a width approximately equal to the height of the slab beam, and is provided with protruding support members on both sides of its inner surface that protrude in a shape mating with the front and rear surfaces of the slab beam.

[0034] Accordingly, when the mating fixing piece is seated on the front and rear surfaces of the connection part of the slab beam, the central portion of the inner surface of the mating fixing piece makes surface contact with the outer surface of the front and rear plates of the beam connector, and the protruding support members on both sides are mated to the front and rear surfaces of the connection part of the slab beam, resulting in a state of close contact. With the mating fixing piece seated on the front and rear surfaces of the connection part of the slab beam as described above, the connection of the slab beam through the mating fixing piece is achieved by inserting a pin through the pin insertion holes formed on both sides of the mating fixing piece into the opposite mating fixing piece.

[0035] Next, the panel bracket is joined to the slab beam at multiple intervals through extrapolation. The bracket body of the panel bracket has a hollow portion that roughly matches the cross-sectional shape of the slab beam, and a pair of fixing pieces extending from the upper part of the bracket body at an interval and facing each other are inserted between these fixing pieces. Then, the slab panel is fixed to the slab beam by the panel bracket through the fastening of a fixing pin that penetrates the fixing piece and the side wall of the slab panel, with the side wall of the slab panel inserted between the fixing pieces.

[0036] Meanwhile, the upper part of the support is provided with a connecting rod insertion hole into which the connecting rod of the beam connector is inserted, and below it, a stopper or elastic stopper is installed to prevent the slab panel assembly from falling directly to the floor.

[0037] In addition, a support guide is installed immediately below the aforementioned connecting rod insertion opening to induce a gradual descent of the slab panel assembly.

[0038] In the present invention, since the slab beam can be connected on the floor using only the above-mentioned mating fixing piece and beam connector, the installation of the slab panel formwork can be performed more easily.

[0039] When assembling a slab panel assembly according to the present invention, the slab beams to be connected are first arranged in a straight line on the floor at a predetermined interval, and then the slab beams are connected in a straight line by using a fitting fixing piece to mount them in close contact with the front and rear surfaces of the slab beam connection part and fastening the pin.

[0040] Next, panel brackets are mounted on each slab beam of the slab beam assembly in which the slab beams are connected, and beam connectors are seated between each beam connection part equipped with a fitting fixing piece. Then, the slab beam assembly is lifted and adjusted to an appropriate position between the soffit lengths, and then a support is erected from the floor so that a connecting rod extending to the lower part of the beam connector is inserted into the top of the support, thereby completing the installation of the slab beam assembly.

[0041] Next, the construction of the slab panel assembly is completed by arranging the slab panels in a grid pattern on the slab beam connector and using the beam connector mounted on the slab beam to fix the slab panels onto the slab beam.

[0042] The process of filling concrete slurry onto the slab panel formwork constructed as described above and dismantling the slab panel formwork when curing is completed over time is almost identical to the dismantling process of the slab panel formwork by the conventional drop construction method, but one difference is that there is no need to remove the fixing bracket connecting the soffit length and the slab beam, and since the slab panel on the slab beam is fixed by the panel bracket, movement or tilting of the slab panel is eliminated during the descent process, allowing for a stable and gradual descent of the slab panel assembly to the stopper of the support. Effects of the invention

[0044] The present invention enables a robust and stable connection of the slab beam connection portion through a fitting fixing piece that is mounted on the slab beam connection portion at the top of the support and connects the slab beams in a drop construction method for a slab panel formwork assembly for construction, and accordingly, ensures reliable load support without causing deformation of the slab panel assembly during the construction of the slab concrete wall.

[0045] In addition, the construction slab panel formwork assembly of the present invention has the advantage of making the dismantling of the slab panel assembly much easier by eliminating the need for the removal of the fixing bracket between the soffit length and the slab beam, which was required when dismantling a conventional slab panel assembly.

[0046] In addition, in the slab panel formwork assembly of the present invention, since the slab panel is fixedly supported on the slab beam by the panel bracket even after the support on the soffit length is released, movement or tilting of the slab panel that may occur during the lowering process of the slab panel assembly is prevented, thereby enabling stable lowering of the slab panel assembly.

[0049] The specific concrete slab formwork installation and dismantling process using the device, including the above-mentioned objectives and specific configurations of the present invention, will be understood in more detail through the detailed description with reference to the drawings below.

[0050] First, FIG. 5 is a perspective view of a filler panel, a beam connector, and a mating fixing piece before assembly according to an embodiment of the present invention, and FIG. 6 (a) and (b) are a front view and a side view of the beam connector of FIG. 5.

[0051] As described above, a beam connector (50) according to one embodiment of the present invention has a square planar upper surface (51) with a square support insertion hole (51a) formed in the center, and front and rear plates (52a, 52b) that are wider at the top and narrower at the bottom are extended downward in parallel with a gap narrower than the width of the upper surface, and a connecting rod (53) that is equipped with a stopper hook (54) extends downward from the inner center, passing between the front and rear plates (52a, 52b).

[0052] Meanwhile, the filler panel (55) has a rectangular cross-section support (56) that extends from the center of the bottom surface of the rectangular panel body (55a) into the support insertion hole (51a) formed on the upper surface of the beam connector (50). At this time, the panel body (55a) of the filler panel (55) has the same height as the slab panel (not shown in the drawing), and pin holes are formed on four sides for connection with adjacent slab panels.

[0053] Next, a pair of mating fixing pieces (60) mounted on the front and rear of the slab beam connection section with the beam connector (50) in between are long, hollow aluminum plates, and protruding support members (61) are formed on both sides of the inner surface of the plates in a shape that is mated to the front and rear surfaces of the slab beam (not shown in the drawing). At this time, the end of the protruding support member (61) facing the beam connector (50) is formed as an inclined side end identical to the side end of the front and rear plates (52a, 52b) of the beam connector (50).

[0054] Meanwhile, FIG. 7 is a front view of the beam connector and mating fixing piece of FIG. 5 mounted on the slab beam connection part, FIG. 8 is a cross-sectional view along line AA of FIG. 7, and FIG. 9 is a cross-sectional view along line BB of FIG. 7, and the configuration of the slab beam connection part is explained with reference to these drawings.

[0055] As shown in FIG. 7, a fitting fixing piece (60) is mounted on the front and rear surfaces of a connecting section in which a slab beam (70) to be connected is arranged in a straight line adjacent to both sides with the beam connector (50) in between. In this mounted state, the middle area of ​​the fitting fixing piece (60), that is, the area between the two protruding support members (61), maintains a state of close contact with the outer surface of the front and rear plates (52a, 52b) of the beam connector (50) as shown in FIG. 8, and the two outer protruding support members (61) are seated on the front and rear surfaces of the recess of the "I"-shaped slab beam (70) while also maintaining a state of close contact as shown in FIG. 9. Although not shown in the drawings, the connection and fixation of the slab beam (70) are achieved by fastening a pin that penetrates the two protruding support members (61) and the slab beam (70) in the above-mentioned state of the fitting fixing piece (60).

[0056] As described above, the joint fixing piece (60) according to the present invention has an upper and lower width that is approximately equal to the height of the slab beam (70) to be connected, and when mounted on the connection part of the slab beam (70), the central inner surface is in close contact with the front and rear plates (52a, 52b) of the beam connector (50), and the outer surface of each protruding support member (61) is in contact with the recessed surface of the slab beam (70) in a jointed state, and the connection and fixing are achieved through pin fastening, thereby strengthening the joint strength through the expansion of the joint fixing piece (60) joint surface.

[0057] In other words, the joint portion of the beam connector (50), the mating fixing piece (60), and the slab beam (70) to be connected is designed such that the outer surface of the protruding support member (61) of the mating fixing piece (60) is mated in surface contact with the recessed opposite surface of the slab beam (70), and the flat inner surface of the area between the two mating fixing pieces (60) is in close contact with the outer surface of the front and rear plates (52a, 52b) of the beam connector (50), thereby maintaining a high joint strength.

[0058] Next, FIG. 10 is a perspective view of a panel bracket according to an embodiment of the present invention, and FIG. 11 is a cross-sectional view of the panel bracket of FIG. 11 in a state where it is coupled to a slab beam. Since the panel bracket (80) of the present invention is installed in an external form on the outside of the slab beam (70), the bracket body (81) has a left-right symmetrical shape with a hollow portion formed that matches the cross-sectional shape of the slab beam (70), and a fixing piece (82) is formed on the upper part of the bracket body (81), extending parallel to each other with a gap between them, into which the side wall (SPw) of the slab panel (SP) is inserted.

[0059] At this time, a fixing pin insertion hole (82a) is formed in the central part of each of the pair of fixing pieces (82), and a fixing pin (P) that commonly penetrates the side wall (SPw) of the slab panel inserted between the fixing pieces is inserted through it.

[0060] The two adjacent slab panels (SP) are fixedly connected to each other by the fastening of the fixing pin (P) with their respective side walls (SPw) inserted together between the fixing pieces, and are fixed to the slab beam (70) by the panel bracket (80). Meanwhile, unexplained reference numeral 83 is a fastening bolt for fixing the panel bracket (80) in a mounted state to the slab beam (70).

[0061] Meanwhile, FIGS. 12 (a) to (d) are front views showing the process of connecting slab beams using the beam connector and the mating fixing piece of the present invention. In the present invention, the connection of slab beams is not performed in the air at a distance from the floor where the slab beams are installed, but is performed on the floor.

[0062] First, as shown in (a) of FIG. 12, a beam connector (50), a fitting fixing piece (60), and a slab beam to be connected (70) are prepared, and the slab beams to be connected (70) are arranged in a straight line at a certain distance from each other, and a panel bracket (80) is mounted on each slab beam (70).

[0063] Next, as shown in (b) of FIG. 12, a pair of mating fixing pieces (60) are placed on the front and rear surfaces of the connection part of the slab beam (70) to be connected, and then a fastening pin (P) is fastened to make a straight connection. Then, as shown in (c) of FIG. 12, a beam connector (50) is inserted into the space between the slab beams (70) to be connected that are connected by the mating fixing pieces (60).

[0064] Next, the slab beam (70) connector connected as described above is lifted and positioned between the soffit lengths (not shown in the drawing) mounted on the top of both wall panels (not shown in the drawing), and a support (not shown in the drawing) is erected from the floor so that the connecting rod (53) extending to the lower part of the beam supporter (50) is inserted into the top of the support, thereby supporting the slab beam connector (71).

[0065] Next, as shown in (d) of FIG. 12, the support (56) of the filler panel (55) is inserted into the support insertion hole (51a) on the upper surface of the beam connector (50) of the slab beam connector (71), while the slab panel (SP) is supported using the panel bracket (80) mounted on each slab beam (70).

[0066] Subsequently, the assembly of the slab panel formwork for constructing the slab wall is completed by arranging the slab panels (SP) seamlessly on the slab beam connector (71) and connecting them to each other by fastening connecting pins to the side walls of adjacent slab panels.

[0067] Meanwhile, FIG. 13 is a cross-sectional view showing the process of constructing a slab concrete wall using a slab panel formwork assembly installed through the work (a) to (d) of FIG. 12, and as shown, a support guide (100) is mounted on the outer surface of a support (90) below the beam connector (50).

[0068] In this way, the assembly of the architectural slab panel assembly of the present invention is completed, concrete is supplied over the assembled slab panel, and curing is achieved over time.

[0069] Once the curing of the concrete for slab construction as described above is completed, the slab panel assembly is dismantled. FIG. 14 shows the dismantling process of such a slab panel formwork assembly using the drop construction method.

[0070] In order to separate the slab panel formwork assembly from the bonding surface with the cured slab concrete in the state of Fig. 13, the side of the drop key (110) is first struck to move the large diameter portion into the drop key insertion groove, thereby releasing the locking state by the drop key.

[0071] Next, when the slab panel assembly is separated from the slab concrete adhesive surface using a slab panel dismantling tool (not shown in the drawing), the load of the slab panel assembly is transferred to the support guide (100), and the slab panel assembly including the slab beam (70) begins to descend along the support (90) by means of the function of the reinforcing member provided in the support guide.

[0072] The gradual lowering of the slab panel assembly by the support guide (100) as described above is stopped when the bottom surface of the support guide (100) comes into contact with the stopper (91) mounted on the support (90), resulting in the state shown in FIG. 15. During the lowering process of the slab panel assembly, the slab panel (SP) supported by the slab beam connector (71) is fixedly supported on the slab beam (70) by the panel bracket (80) even after the support on the soffit length (SP) is released, so movement or tilting of the slab panel that may occur during the lowering process is prevented.
