Description

Large-scale beam slab system formwork and beam slab construction method using the same {LARGE CONCRETE MOLD FOR CROSSBEAM AND SLAB, AND METHOD FOR CONSTRUCTING CROSSBEAM AND SLAB USING THIS SAME}

The present invention relates to a beam and slab formwork, and more particularly, it is possible to simultaneously and independently cast a beam and a slab, and to easily and quickly respond to changes in the size of a beam and a slab, it is possible to construct a beam and a slab. The present invention relates to a large-sized beam slab system formwork and a beam slab construction method using the same, which distributes concrete pressure from the slab formwork through the beam formwork by connecting the formwork, while securing a wide working space under the slab formwork to improve workability.

In general, when building a building, in order to form a slab that divides the floor and the floor, a frame is formed so that beams and flows are formed by connecting a plurality of rectangular formwork, and after the frame is completed, concrete is poured to cure. After the concrete is cured, a number of formwork is dismantled, and the dismantled formwork is manually transported to the upper layer to form the entire frame again to pour the concrete. That is, the method of building between floors and floors is to arrange the formwork at a certain height (height determined by the design of the building) from the floor, and then place a plurality of supporters between the formwork and the floor to support the formwork. In general, after forming a frame of the upper floor by connecting a plurality of formwork horizontally, concrete is placed inside the formwork.

On the other hand, recently, slabs and beams have been poured together, and this is achieved by a form (so-called "table foam") for pouring slabs and beams together.

Conventional table foams consist of a slab formwork, a beam formwork, and a stiffener supporting the slab formwork and the beam formwork at the bottom (composed integrally with the slab formwork and the beam formwork), and from the ground through a height-adjustable support erected on the ground. It is installed at a certain height.

Table foams having such a configuration are increasingly used because the slab formwork, the beam formwork, and the reinforcement are integrally configured to have excellent workability.

However, since such a conventional table form is too bulky to be transported and used after being manufactured in a factory, logistics costs are very expensive, and in particular, there is a problem in that the burden of logistics costs is very large during overseas construction.

In addition, there is a difference in height between the slab and the beam, and thus the types of supports for supporting the slab form and the beam form are different from each other. Therefore, there is an inconvenience in handling (storing, transporting) different types of supports, and there is a problem in that workability is very poor since the operator must find a support suitable for the slab formwork and the beam formwork at the construction site.

Patent document (Registration Patent No. 10-1586858) is a first step of assembling a formwork member for concrete pouring of slabs and beams and a reinforcing rod for reinforcing the formwork member with a clamp to produce a table foam; A second step of installing the table foam produced through the first step at a construction location of the slab through a single type of support having the same height; A third step of constructing slabs and beams by pouring and curing concrete on the formwork member of the table foam installed through the second step; And a fourth step of demolding the table foam after curing the slab and the beam according to the 34th step, and the first step includes a formwork formed in a flat plate shape, a casting surface bent at a right angle for pouring the corners, and the In-corner joints consisting of clamp connections formed on both sides of the pouring surface, and out-corner joints having clamp connections at right angles to each other are selected to fit the cross section of the slab and beam, and then connected with clamps to manufacture formwork members. Step 1, including the step 1-2 of assembling the reinforcement through the clamp of the same configuration as the clamp used in step 1-1, the formwork member is composed of a split type, but Since it is not a structure that responds easily, it is difficult to share it in not only one site but also various sites.

Is fixed to The two fasteners are disposed on both sides, centering on the support fixing part 51b, because, if only one fastener is fastened, the fastener functions as a hinge and the fixing bracket 51 rotates under the guidance of the fastener. This is because 50) is separated from the wall-side formwork 25.

The support fixing part 51b is formed on at least one side of the front and rear of the crossbar fixing part 51a and surrounds the circumference of the support 50 (a type without one side among a square or a square), and the support is provided through two fasteners at the top and bottom. Fix (50) to prevent the support (50) from moving.

The aforementioned wooden core support bar 29 is fixed (welded, fastener, etc.) to the upper end of the support fixing portion 51b.

8B is another exemplary view of the fixing bracket 51-1, wherein the fixing bracket 51 is fixed to the yoke member 26, whereas the fixing bracket 51-1 of the present embodiment is an angle 23 There is a difference in that it supports the support 50 while being fixed to.

The fixing bracket 51-1 is configured to be fixed through pins while the support fixing part 51b covers at least both sides of the support 50 facing each other, and the angle fixing part 51b next to the support fixing part 51b ( 51c) is formed.

The angle fixing part 51c is protruded from the support fixing part 51b so as to be inserted into the space between the reinforcing member side fixing part 23a of the angle 23 and the formwork support part 23b.

Since the fixing bracket 51-1 can be installed on the angle 23 through fasteners (bolts, nuts, pins, etc.), it is fixed to the support 50 through the support fixing part 51b. It may be installed by fixing the support 50 to the angle 23 with fasteners (bolts, nuts, pins, etc.) without being fixed to the angle 23 itself.

The angle fixing part 51c may be configured with a jaw so as to be caught on the jaw when the jaw is formed on the angle 23.

On the other hand, since the support 50 may have weak support only by being fixed to the yoke member 26, a turnbuckle-type adjustment device 60 may be applied.

9 to 12 show an example of application of the turnbuckle-type adjuster 60, and the turnbuckle-type adjuster 60 is a pair of bolts 61 and 62 having screws in opposite directions and these bolts. It is fastened between and consists of a nut 63 that spreads or collects bolts depending on the direction of rotation, and FIG. 9 shows a turnbuckle-type adjuster 60 between the supports 50 and the bottom of the support 50 (of the bottom formwork Below] is a configuration in which the support 50 is rotated through a fastener (fastening only one of the two fasteners) to spread or gather, and FIG. 10 shows the two adjusters 60-1 and 60-2 as a support ( 50), one bolt 61 is connected to the yoke member 26 and the other bolt 62 is connected to the bottom of the support 50 (below the bottom formwork) and is configured to act in opposite directions, 11 shows that two adjusters are applied, one adjuster 60-1 has a bolt connected to the yoke member 26 and the bottom of the support 50, and the other adjuster 60-2 has a bolt support It is configured to act in opposite directions by being connected to the upper part of the 50 and the yoke member 26, and FIG. 12 shows the yoke member ( 26) is connected to the bottom of the support 50 and pulls or pushes the bottom of the support 50, and FIG. 1 shows that two turnbuckle-type adjusters 60 are symmetrically disposed on the upper part of the yoke member 26. This is the way.

On the other hand, the cross-sectional area of the beam becomes smaller as it goes from the basement to the ground in the building, so the size of the beam form must be changed. Manufacturing a beam formwork of various cross-sectional areas requires a lot of cost and work according to manufacturing and storage, and in the present invention, a spacer 70 is applied to adjust the width.

The spacer 70 is for adjusting the left and right width of the modular beam formwork 20, for example, it is additionally interposed between the girder 21 and the reinforcing member 22 to increase the width, and a square pipe is preferable and a particularly wide surface It is a square tube (a yoke cut) with (for example, 100mm length) and a narrow side (for example, 50mm length).

That is, two widths can be matched with one spacer 70, and FIG. 13 uses a wide surface and FIG. 14 uses a narrow surface.

For example, when constructing the lower floor beam, the spacer 70 is installed using a wide surface as shown in FIG. 13, and when the upper floor beam is constructed, the spacer 70 is separated in the state of FIG. It is installed using cotton.

The spacer 70 is installed by a bolt (bolt fixing the angle 23) by forming a hole on each side in order to use the assembly structure of the girder 21, the reinforcement 22 and the angle 23 as it is. .

<Example 2>

As shown in FIGS. 15 and 16, the modular beam formwork 20-2 of Example 2, compared to Example 1, is that both the floor-side formwork 24-1 and the wall-side formwork 25-1 are foam. Consisting of a panel of euroform and aluminum foam, the angle 23-1 is configured to support the bottom-side formwork 24-1 and the wall-side formwork 25-1, while the girder 21 of Example 1 and There is a difference in that the reinforcing member 22 is not used, and the yoke member 26, the neck core support bar 29, the support 27, and the support 50 are configured in the same manner as in the first embodiment. Further, a joist wire 28 may be added to the bottom of the angle 23-1 in a direction orthogonal to the yoke member 26.

The angle (23-1) has a feature of supporting both the floor-side formwork (24-1) and the wall-side formwork (25-1), and supports both left and right sides of the bottom of the floor-side formwork (24-1) at the bottom. The first support (23-1a), the first support (23-1a) is formed in the upper (vertical) to support the side of the bottom-side formwork (24-1) (23-1b), alignment It is formed in the transverse direction in (23-1b) and is composed of a second support part 23-1c that supports the wall-side formwork 25-1 at the bottom, and is made of various materials and manufacturing methods such as aluminum and iron.

The first support part 23-1a, the alignment part 23-1b, and the second support part 23-1c are for fixing the floor-side formwork 24-1 and the wall-side formwork 25-1, respectively. A number of holes are provided. As the assembly means using the hole, bolts, nuts, pins, and clamps are used.

The first supporting part 23-1a supports and supports the bottom of the floor-side formwork 24-1, and is assembled with the floor-side formwork 24-1a through assembling means such as bolts, nuts, pins, and clamps. do.

At this time, only the first supporting portion 23-1a and the bottom-side formwork 24-1a may be assembled, or the yoke 26 and the first supporting portion 23-1a and the bottom-side formwork 24 -1a) may be assembled through a single assembly means.

In addition, the angle 23-1 is formed with a support jaw protruding upward from the second support portion 23-1c so as to stably maintain the wall-side formwork 30 erected.

The support jaw protrudes upward from the outer edge of the second support portion 23-1c to cover the bottom of the wall-side formwork 25-1, and may be formed entirely on the second support portion 23-1c. Or, a plurality of them may be formed at regular intervals.

In addition, the angle 23-1 includes a yoke 26 and a reinforcing material assembly 23-1d for fixing.

The reinforcing material assembly part 23-1d is formed in a line in the transverse direction with the first support part 23-1a on the opposite side of the first support part 23-1a based on the alignment part 23-1b. (26) It is put on top. Of course, the reinforcing member assembly portion 23-1d is assembled through the yoke member 26 and the assembly means including one or more holes.

Through the above structure, it is possible to assemble the floor-side formwork 24-1 and the wall-side formwork 25-1 together with only a pair of angles 23-1.

Additionally, the pair of angles 23-1 may be connected through a connecting rod.

The pillar pouring plate 30 is a conventional plywood, and is used after being cut to fit the gap between the modular slab formwork 10 and the modular beam formwork 20.

As shown in FIGS. 1 and 17, the slab formwork holder 40 is formed at the bottom of the holder body 41 and the holder body 41, and is seated and fixed on the yoke member 26 of the modular beam formwork 20. It is formed on the fixing plate 42, the holder body 41, and is composed of a holder 43 supporting the yoke 14 of the modular slab formwork (10).

The holder body 41 is made of a shape and material capable of withstanding the load of the modular slab formwork 10 such as square pipes and rods.

The fixing plate 42 is formed in a plate shape (welded and fixed) with a cross-sectional area larger than that of the holder body 41 at the lower end of the holder body 41, and is fixed to the yoke member 26 of the modular beam formwork 20.

The fixing plate 42 can be fixed by a permanent fixing type or a movable fixing type.

The permanent fixing type is to fix the fixing plate 42 to the yoke member 26 by welding.

The movable fixed type can move the position of the slab formwork holder 40 according to the distance change between the modular slab formwork 10 and the modular beam formwork 20, and the slab formwork holder 40 is the holder body 41 A moving guide plate 44 is formed at the bottom of the unit, and the moving guide plate 44 moves along the yoke member 26 using the yoke member 26 as a rail. Here, the slab formwork holder 40 must be configured to maintain the moved state, for example, by screwing the screw-type fastener 45 to the moving guide plate 44 to move through the rotation of the fastener 45 A method of fixing the guide plate 44 to the yoke member 26, while drilling a multi-stage positioning hole in the yoke member 26, and drilling an alignment hole communicating with the positioning hole in the moving guide plate 44, It is possible to fix by fastening fasteners (pins, bolts, nuts, etc.) to the alignment holes.

The moving guide plate 44 may be an open type covering a total of three surfaces of the yoke member 26 on both the top and front and rear surfaces, and a closed type covering all circumferential surfaces of the yoke member 26. In the case of a closed type (for example, a square frame), the fastener 45 is preferably applied to the bottom of the closed moving guide plate 44 so that the operator can tighten the fastener 45 on the ground.

It is preferable that the slab formwork holder 40 is configured such that the height of the beam and the slab can be adjusted so that the height of the beam and the slab is not replaced and used.

For example, the slab formwork holder 40 is a double-tube type outer cylinder having a relatively large outer cylinder, an inner cylinder having a size smaller than that of the outer cylinder, and being inserted into the outer cylinder so as to be elevating, and a fixture fixing the inner cylinder in a height-adjusted state. Consisting of, the outer cylinder may have a multi-stage height adjustment hole, and the inner cylinder may be configured with an alignment hole through which the fixture is fastened through the multi-stage height adjustment hole.

Since the slab formwork holder 40 is erected at a certain height, it may cause bending deformation due to a large load, and a safety member 46 (shown in FIG. 20) may be additionally applied to compensate.

The safety member 46 can be used in various shapes such as plate, strip, angle, and tubular, and both sides are modular beam formwork 20 (for example, support 50) and a clamp on the slab formwork mount 40. Or it is fixed through bolts and nuts or pins).

In addition, the safety member 46 may be configured to be adjustable in length in consideration of the position change of the slab formwork holder 40, for example, in the form of a turnbuckle. Since the turnbuckle-type safety member 46 can move the slab formwork holder 40 through its length adjustment, it also functions to adjust the position of the slab formwork holder 40.

The modular slab formwork (10) and the modular beam formwork (20) are installed through supports, respectively, to allow the construction of the slab and beam, and these supports are the modular slab formwork (10) and the modular beam formwork (20). A combined transport support 80 (refer to FIG. 19) that can only function to support or can also serve as transport may be applied.

The combined transport support 80 is composed of two or more supports 81 and 82 in which an assembly of wheels 83 and 84 and a traveling actuator are configured at the bottom, respectively, and a connecting rod 85 connecting the supports 81 and 82.

The supports 81 and 82 are each composed of an outer cylinder and an inner cylinder to be height adjusted, and the inner cylinder is supported on the ground and the outer cylinder is supported on the modular beam formwork 20 while being liftably coupled to the outside of the inner cylinder. The height adjustment of the outer and inner cylinders is performed by hydraulic cylinders 81a and 82a. The hydraulic cylinders 81a and 82a are supported by the inner and outer cylinders and raise or lower the outer cylinders by hydraulic oil.

The traveling actuator is capable of rotating and driving the wheels 83 and 84, such as a hydraulic motor or an electric motor, and a small size mounted on the supports 81 and 82 is preferable. In the drawing, it is shown that the wheels 83 and 84 are floating on the ground, but FIG. 19 shows a state in which the combined transport support 80 is not moved by the wheel, that is, a concrete pouring-cured state. It is configured to descend to touch, for example, the wheels 83 and 84 and the traveling actuator are installed at the lower circumference of the outer cylinder, and the outer cylinder is lowered so that the wheels 83 and 84 contact the ground during transportation.

The hydraulic cylinders 81a and 82a and the traveling actuator are driven by an operator's operation, and the operation can be performed in both wired and wireless methods.

At this time, it is also possible to put a nail or the like to prevent the pillar pouring plate 30 from separating.

4. Concrete pouring.

Through the whole process, a pouring surface (both pouring plate-pillar pouring plate-slab pouring plate) for concrete pouring of beams and slabs is formed, and concrete is poured on this pouring surface.

According to the installation structure of the modular slab formwork 10, the slab formwork mount 40, and the modular beam formwork 20, the pressure of the concrete is transmitted to the slab formwork mount 40 through the modular slab formwork 10. Subsequently, it is transferred from the slab formwork holder 40 to the slab of the floor through the modular beam formwork 20 again.

Since the modular slab formwork (10) is supported by its own support (17) and is supported by the modular beam formwork (20), the support (17) of the modular slab formwork (10) as the retention period of concrete elapses. When it is possible to reduce the number of) and support with only the modular beam formwork 20, all supports 17 can be removed. Thus modular slab formwork (10)

By removing the support 17 in this way, a wide space is provided under the modular slab formwork 10, so that the movement and work of the operator are very easy, and the work using the equipment is very easy.
