Description

Assembling shuttering for building

Technical Field

The present invention relates to an assembly form for a building, and more particularly, to an assembly form for a building, which can be easily assembled.

Background

Walls of buildings such as apartments, buildings, and general houses are formed by forming a basic shape using a formwork, pouring concrete, and curing. In general, a form is a temporary building material for keeping concrete in a prescribed shape and size, preventing moisture required for curing thereof from leaking, and protecting concrete from external impact, which is used until the curing of concrete is finished. Such formwork construction has a great influence on the concrete construction process and result, and has a great influence on finishing work, thus putting a great deal of effort on the formwork construction.

Such a form is generally divided into a one-piece form (Euroform) formed by bonding plywood to a front surface of a steel frame and an advanced aluminum form formed of an aluminum material.

The whole template in the past can be demolishd and retrieve and reuse after the construction of pouring, but because the weight of the frame that comprises thicker plywood and steel is heavy, the operation personnel is difficult to operate by oneself, therefore whole template can only be made into small-size, is difficult to connect during the construction.

On the other hand, korean laid-open patent publication No. 10-1998-0009704 "aluminum monolithic form (concrete form) and method for manufacturing the same" discloses an aluminum form formed by a method comprising: as a first process of the extrusion molding process, a main plate is extruded by a conventional extruder from an aluminum (Al) material, peripheral frames are formed on the left and right side surfaces of the main plate, and a plurality of reinforcing protrusions are integrally formed in the main plate along the length direction; a second step of forming a connection hole by processing a side surface of the main plate extruded in the first step as the extrusion forming step, and processing the main plate so that a reinforcing frame can be provided at both ends; as a third step of the reinforcing frame joining step, a reinforcing frame made of aluminum (Al) is additionally integrally provided by welding at reinforcing frame installation portions formed by machining both ends of the main plate in the second step as the machining step.

However, in the conventional aluminum mold plate, in the process of welding the reinforcing frames to both end portions of the main plate provided with the side surfaces and the reinforcing protrusions, since the shape of the joint portion between the main plate and the reinforcing frame is complicated, it is difficult to weld along the peripheral line of the main plate in contact with the reinforcing frame, and the defective fraction generated in the welding process is high.

In addition, in the case of aluminum, holes are easily generated in the plate material during welding, so that an excessively thick thickness is required, which results in an increase in load of the form and production unit price, and thus it is preferable to minimize the welded portion.

Detailed Description

Before the present invention is described, in the following embodiments, the same reference numerals are given to the components having the same structure, and the first embodiment is representatively described, and in other embodiments, the structure different from the first embodiment is described.

Hereinafter, an assembled formwork for a building according to a first embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of an assembly form for construction according to a first embodiment of the present invention, and fig. 2 is an exploded perspective view of fig. 1.

The construction assembled formwork of the present invention shown in the above-mentioned figures includes several major parts of a main frame 110, a second flange part 120, a reinforcing bar 130 and a reinforcing bar 140.

In the present embodiment, for convenience of explanation, the first axis X is set to be parallel to the short side of the main frame 110, the second axis Y is set to be parallel to the long side of the main frame 110, and the third axis Z is set to penetrate the plate surface of the main frame 110.

The main frame 110 includes: a closed panel 111 whose front face forms a concrete curing space closed face; first flange portions 112 that protrude from both sides of the rear surface of the closing panel 111 in the vertical direction to form both side surfaces of the formwork; and a first coupling portion 115 formed at the center of the rear surface of the closure panel 111 in a direction parallel to the first flange portion 112. On the other hand, the first coupling portion 115 may be configured by a neck portion extending from the plate surface of the closing panel 111 in the third axial direction and a locking portion extending from a distal end portion of the neck portion in the first axial direction. That is, the neck portion preferably has a predetermined distance from the closing panel 111, and this distance is slightly larger than the thickness of the second coupling portion 131 to be described later, so that the second coupling portion 131 can be easily inserted.

The second flange portion 120 is fixed to a short side of the main frame 110 to form upper and lower surfaces of a formwork. On the other hand, in a state where the second flange portion 120 is disposed at the upper end and the lower end of the main frame 110, the contact portion between the second flange portion 120 and the first flange portion 112 and the closing panel 111 may be fixed by welding. In particular, the contact portion between the first flange portion 112 and the closing panel 111, which is in contact with the second flange portion 120, may be formed in a straight shape, and a welding line having a complicated shape is not formed as in the conventional art, so that the number of welding processes can be minimized.

The rib 130 is disposed at the center of the rear surface of the closing panel 111, and a plurality of ribs 130 are disposed in parallel to the first flange portion 112 at intervals, wherein the rib 130 has a second coupling portion 131 formed to protrude from one side of an end portion facing the closing panel 111, and the second coupling portion 131 is inserted into the first coupling portion 115 in the first axial direction and engaged with the engaging portion of the first coupling portion 115 in the third axial direction.

The first flange portion 112 and the reinforcing bar 130 are respectively formed with

insertion holes

113 and 132, the reinforcing bar 140 is rotatably supported while being inserted through the

insertion holes

113 and 132, and

insertion grooves

114 and 133 are formed at one side of the

insertion holes

113 and 132.

On the other hand, the main frame 110, the reinforcing beads 130 and the second flange portion 120 may be formed of an aluminum material, and may be manufactured by

punching insertion holes

113 and 132 in the first flange portion 112 and the reinforcing beads 130 and punching a plurality of coupling holes (not shown) for coupling between die plates in the first flange portion 112 and the second flange portion 120 after extrusion molding by a conventional extruder.

The reinforcing bar 140 is disposed in a first axial direction intersecting the first flange part 112, and is coupled to the first flange part 112 through the reinforcing rib 130, the length of the reinforcing bar 140 is set to be equal to the length of the short side of the main frame 110, and an insertion protrusion 141 is formed on one side of the reinforcing bar 140 to be inserted through the

insertion grooves

114 and 133.

Further, the insertion protrusion 141 is configured such that the reinforcing bar 140 can be rotated in a state of being completely inserted into the

insertion holes

113, 132. Specifically, the insertion protrusions 141 are plural and arranged at both side spaces defined by the beads 130, respectively, the insertion protrusion 141 of one side is configured to have a shape corresponding to a space between the first flange part 112 and the first coupling part 115 of one side, and the insertion protrusion 141 of the other side is configured to have a shape corresponding to a space between the first flange part 112 and the second coupling part 131 of the other side.

Specifically, the first axial length of the insertion projection 141 is set to a length corresponding to the length between the first flange portion 112 and the first coupling portion 115 on the one side and the length between the first flange portion 112 and the second coupling portion 131 on the other side, and the protruding length of the insertion projection 141 is set to a length at which the distal end portion of the insertion projection 141 can be brought into close contact with the rear surface of the closing panel 111 in a state where the reinforcing rod 140 is rotated to the fixed position.

Further, an angular through-hole 142 may be formed in the center of the cross section of the reinforcing rod 140 in the first axial direction, and a plurality of grooves 143 may be formed in the outer circumferential surface of the reinforcing rod 140 in the first axial direction. Such a reinforcing bar 140 can be manufactured by forming a notch portion in the insertion protrusion 141 at a position corresponding to the first flange portion 112 and the reinforcing bead 130 after extrusion molding by a conventional extruder.

The operation of the first embodiment of the above-described assembling formwork for construction will be explained.

In the drawings, fig. 3 is a sectional view taken along a-a ' of fig. 1, fig. 4 is a sectional view taken along B-B ' of fig. 3, fig. 5 is a sectional view taken along C-C ' of fig. 3, and fig. 6 is a view illustrating an assembling process of a reinforcing bar of an assembling formwork for construction according to a first embodiment of the present invention.

The front surface of the closed panel 111 of the main frame 110 forms a closed surface of the concrete curing space, and the first flange portions 112 disposed on both sides of the rear surface of the closed panel 111 form left and right side surfaces of the formwork.

In a state where the second flange portion 120 is disposed at the upper end and the lower end of the main frame 110, respectively, a contact portion with the first flange portion 112 and a contact portion with the closing panel 111 are fixed to the main frame 110 by welding to construct the upper surface and the lower surface of the formwork.

A reinforcing rib 130 capable of fixing the center of the closing panel 111 to the reinforcing bar 140 is disposed at the center of the rear surface of the closing panel 111 of the main frame 110. The second coupling portion 131 of the reinforcing bead 130 protruding to one side of the plate surface is inserted into the first coupling portion 115 formed at the rear surface of the closing panel 111 in the first axial direction so that the second coupling portion 131 is disposed between the closing panel 111 and the catching portion, and thus the third axial direction position of the reinforcing bead 130 is fixed. The reinforcing bar 140 is inserted through the insertion holes 113 and 132 formed in the first flange part 112 of the main frame 110 and the reinforcing bar 130, respectively, so that the rigidity of the mold plate against bending or twisting can be enhanced.

Such a plurality of beads 130 are arranged and are provided at positions where the reinforcing rods 140 are arranged, respectively, so that it is possible to prevent an increase in weight of the form due to the beads 130 being formed at portions where the reinforcing rods 140 are not arranged.

In a state where the insertion protrusions 141 of the reinforcing rods 140 are aligned with the

insertion grooves

114, 133 of the insertion holes 113, 132 (see fig. 6 (a)), the reinforcing rods 140 are inserted through the insertion holes 113 of the one-side first flange part 112 and inserted into the insertion holes 113 of the other-side first flange part 112 after passing through the insertion holes 132 formed in the reinforcing beads 130.

At this time, since the insertion projection 141 is disposed in the space between the first flange portion 112 and the bead 130, the reinforcing rod 140 is in a state of being able to rotate axially in a state where the reinforcing rod 140 is completely inserted and the insertion projection 141 is positioned in the space between the first flange portion 112 and the bead 130. Next, when the reinforcing bar 140 is rotated about the predetermined angle axis, the insertion projection 141 of the reinforcing bar 140 is displaced from the

insertion grooves

114 and 133, and the insertion projection 141 of the reinforcing bar 140 is sandwiched between the first flange portion 112 and the bead 130.

That is, as shown in fig. 6 (b), when the reinforcing bar 140 is rotated such that the front end portion of the insertion projection 141 is in close contact with the rear surface of the closure panel 111, the second coupling portion 131 is pressed in the third axial direction in close contact with the locking portion 115b of the first coupling portion 115, thereby increasing the coupling force between the main frame 110 and the reinforcing bar 130, and also increasing the coupling force between the main frame 110 and the reinforcing bar 140 penetrating the reinforcing bar 130 in the first axial direction.

Furthermore, since the insertion protrusions 141, which are respectively positioned in the spaces on both sides of the bead 130, are closely attached to the side surfaces of the first coupling portion 115 and the second coupling portion 131, the first coupling portion 115 and the second coupling portion 131 can be prevented from being arbitrarily separated by an external force.

Further, since the through-hole 142 formed in the center of the reinforcing rod 140 is formed in an angular shape, the reinforcing rod 140 can be easily axially rotated using a tool having a protrusion having a shape corresponding to the angular through-hole 142, and since the concave groove 143 formed in the outer circumferential surface of the reinforcing rod 140 forms a plurality of corners in the outer circumferential surface of the reinforcing rod 140, the reinforcing rod 140 can be prevented from being arbitrarily rotated in the insertion holes 113 and 132. In addition, since the weight of the reinforcing bar 140 can be reduced by the through-hole 142 and the concave groove 143 formed at the center of the reinforcing bar 140, the material cost and the load of the mold can be reduced to the maximum.

On the other hand, in a state where the reinforcing rod 140 is inserted into the insertion hole 113 of the first flange part 112 of the main frame 110 and the insertion hole 132 of the reinforcing bead 130, the both end parts of the reinforcing rod 140 may be plastically deformed to prevent the reinforcing rod 140 from being separated from the main frame 110.

The assembling formwork for a building according to the present embodiment as described above can reduce the thickness of the plate material compared to the conventional art because the fixing portion by welding is simplified and no complicated welding line is formed. Therefore, not only can the weight of the template be reduced, but also the cost of raw materials can be reduced.

In addition, the reinforcing bar 140 is coupled by an assembling method, so that an automatic assembling process can be enlarged, thereby reducing the manufacturing cost to the maximum.

Further, according to the first embodiment described above, the beads 130 can be disposed only at the coupling positions of the reinforcing rods 140, and thus the beads 130 can be prevented from being excessively positioned at the positions where the reinforcing rods 140 are not disposed, and weight reduction can be achieved. Such a first embodiment is suitable for a case where the second axial direction length of the closure panel 111 is short so that the center portion does not need to be reinforced.

Next, an assembly form for building according to a second embodiment of the present invention will be described.

Fig. 7 is a perspective view of an assembly form for construction according to a second embodiment of the present invention, fig. 8 is an exploded perspective view of fig. 7, fig. 9 is an enlarged sectional view of a portion "a" of fig. 7, and fig. 10 is an operation view illustrating an assembly process of a first coupling part and a second coupling part according to the second embodiment of the present invention.

The assembling formwork for a building according to the second embodiment of the present invention as shown in the above-mentioned drawings is different from the first embodiment in that the main frame 110 is constructed in a divided manner, and the divided main frame 110 is fixed using the reinforcing ribs 130.

Specifically, the center of the closing panel 111 of the main frame 110 is divided into a first body 110a and a second body 110b, and the first body 110a and the second body 110b have a first flange portion 112 formed on one side of the closing panel 111 and a first coupling portion 115' formed on the other side.

The reinforcing bar 130 includes a second coupling portion 131', and the second coupling portion 131' is used to simultaneously fix the first coupling portions 115' formed on the first and

second bodies

110a and 110b, respectively. The first coupling portion 115 'is disposed in the first body 110a and the second body 110b in opposite directions to each other, and a plurality of the second coupling portions 131' are disposed at intervals so that the first coupling portion 115 'of the first body 110a and the first coupling portion 115' of the second body 110b can be simultaneously fixed in a state where they are in contact with each other.

In particular, the first and second coupling portions 115 'and 131' are configured in the shape of a circular arc hook that engages with each other, and have a coupling structure as follows: as shown in fig. 10 (a), in a state where the first body 110a and the second body 110b are arranged in the oblique direction and the first coupling portion 115 'and the second coupling portion 131' are engaged with each other, the first body 110a and the second body 110b are rotated to couple the first coupling portion 115 'and the second coupling portion 131' as shown in fig. 10 (b). Further, a stopper 116 is provided at a lower end of a surface of the second body 110b of the first body 110a facing each other, and the stopper 116 can be closely attached to each other to prevent further rotation in a state where the closing panel 111 of the first body 110a and the closing panel 111 of the second body 110b are arranged on the same plane.

Next, when the reinforcing bar 140 is inserted into the insertion holes 113 and 132 formed in the first flange part 112 and the reinforcing bar 130 and the reinforcing bar 140 is rotated by a predetermined angle for fixing, the insertion protrusion 141 of the reinforcing bar 140 is brought into close contact with the closing panel 111, so that the coupling force between the main frame 110 and the reinforcing bar 130 can be increased, and the first coupling part 115 'is restricted from being rotated in a direction spaced apart from the second coupling part 131', so that the first coupling part 115 'and the second coupling part 131' can be prevented from being arbitrarily separated by an external force. The coupling structure and the fixing process of the reinforcing bar 140 are the same as those of the first embodiment, and thus a detailed description thereof is omitted.

The scope of the claims of the present invention is not limited to the embodiments described above, but may be implemented by various embodiments within the scope of the appended claims. Various ranges that can be modified by those skilled in the art without departing from the gist of the present invention claimed in the claims also belong to the scope of the present invention recited in the claims.
