Description

Light weight assembly for hollow and light slab structure for fixed installation on reinforced truss deck plate

The present invention is an assembly fixedly installed on the truss girder of the improved reinforced truss deck plate consisting of a truss girder and a plate developed for the long span,

The present invention relates to a lightweight molding assembly and a light weight slab structure using the same for fixed installation on an improved reinforced truss deck plate which is easy and economical to construct.

In buildings, slabs are horizontal members that are indispensable for use in order for people to live and live.

However, since the load acting on the slab acts in an adverse vertical direction rather than a structurally advantageous horizontal direction, the slab is structurally weak and a member to which a countermeasure is required. In addition, since it is not the main structural material that maintains the structure in response to external forces such as columns and beams, it needs to be made to function as lightly and efficiently as possible.

In small buildings, it is common to divide a reasonable area by beams, but when the span between pillars forms a long space, the height of the beam supporting the slab increases, which increases the height of the floor.

Therefore, a lightweight slab with high resistance to vertical loads is required without reducing the beam dancing and raising the floor height.

Traditional slab structures that meet these needs include joist slabs, waffle slabs, hollow core slabs, and the like.

The joist slab and the waffle slab have the disadvantage of complicated formwork by densely installing small dance beams in one or two directions, and hollow core slabs are stressed inside the slab. Since the construction to make the hollow part is complicated by lightening the part that hardly resists the light weight, it is not suitable for the construction method, which is the main purpose of the labor force reduction due to the decrease of the technical skill of the worker and the increase of labor cost.

In order to solve the problem of constructability, many methods using Half-PC have been developed and widely used in foreign countries, but in Korea, it is extremely limited in terms of transportation and yardage due to road and site conditions.

Deck plate has been commercialized effectively in the structural aspect such as steel plate structure, solid support, and formwork method.After that, rebar is pre-assembled in truss type and integrated deck plate, that is, reinforced truss deck plate, minimizes reinforcement and improves workability. It is widely used mainly on steel structure, although it is possible to shorten the air due to labor reduction, which is somewhat expensive.

However, the existing reinforced truss deck plate is for short spans of about 4m, and when applied to long spans, it is not possible to use it, and the slab load increases, which is also structurally disadvantageous, such as coupling with a hollow slab. A countermeasure is needed.

Accordingly, the present inventors utilize the existing reinforced truss deck plate and maintain the performance despite reducing the load of the slab, 'lightweight molding assembly for fixed installation on the reinforced truss deck plate applicable to the long span and the same The light weight slab structure (Patent Application No. 10-2009-0110326) used was developed.

However, the present invention has a problem that the deck plate is heavy to work with a manpower is necessary to use a machine such as a crane.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the related art. The purpose is as follows.

First, it provides a lightweight molding assembly for fixed installation on an improved reinforced truss deck plate that minimizes the number of parts for long spans and can be easily assembled and installed on an integrated reinforced truss deck plate with pre-assembled rebars in a truss type. And to provide a lightweight slab structure using the same.

It is a member that is formed of a lightweight material to have a plurality of fixing key insertion hole 120 is formed through the vertical, the truss girder insertion portion 130 so that the truss girder (D10) can be inserted into both ends of the lower The main body 100 is formed; And a handle 210 is formed on the bent upper portion in a bent shape of the steel bar as a whole, and a latch fixing portion 220 is formed on the bent lower portion, from the latch fixing portion 220 to the main body 100. A plurality of fixing keys 200 inserted into the fixing key insertion holes 120 and disposed through the main body 100, including the fixing keys 200 fixed through the fixing keys 200 through the main body 100. When the handle 210 of the key 200 is rotated, the latch fixing part 220 of the fixing key 200 is caught under the latch D14 of the truss girder D10 of the improved reinforcement truss deck plate D.

The main body 100 may be manufactured in various planes such as rectangular, square, and circular, as long as it maintains the shape of the center hole as a whole. However, in order to minimize stress resistance and facilitate slab concrete (C) casting when permanently embedded in the slab, it is preferable to manufacture the outer circumference by curved surface treatment.

The thickness of the main body 100 is the slab concrete (C) after placing the entire slab structurally stable function, and to thicken as much as possible within the limit suitable for the fire-resistant structural regulations is effective to reduce the weight of the slab. In other words, either the upper or lower portion of the main body 100 in the thickness of the entire slab maintains the concrete thickness of 10cm by the fire resistance regulations and the other side of the maximum thickness of the main body 100 can be applied to the remaining thickness of 5cm Could be. The above embodiment is a case where the thickness of the concrete 10cm by the fire resistance is maintained in the lower portion of the main body 100.

In addition, although not shown in the drawing, a latch insertion part may be formed in the center of the lower portion of the main body 100 so that the latch D14 may be inserted. Since the truss girder D10 and the latch D14 are regularly installed at regular intervals, the truss girder insertion part 130 and the latch insertion part make the main body 100 separate from the improved reinforcement truss deck plate D. It is arranged regularly without any means.

In addition, a plurality of spacers 150 protruding to support the slab upper transverse rebar S3 may be further formed on the upper portion of the main body 100 as illustrated in FIG. 10.

At this time, the bottom of the fixing key insertion hole 120 is disposed in parallel with the latch inserting portion, which causes the latch (D14) to be automatically fixed to the latch fixing portion 220 of the fixing key 200 Closely contacted in parallel.

When the fixing key 200 rotates the handle 210 of the fixing key 200 in a state where the fixing key 200 is penetrated through the main body 100, the latch fixing part 220 of the fixing key 200 is a reinforced truss deck plate (D). The main body 100 is fixedly installed to the improved reinforcement truss deck plate (D) due to the fixing key 200 as it is caught under the latch D14.

The fixing key 200 is mainly manufactured by bending or welding a circular steel bar or rebar, and the latch fixing part 220 has a length enough to be caught by the latch D14 during rotation.

In addition, the handle 210 of the fixing key 200 may also serve as a spacer of the upper slab upper slab (S2) or the upper slab horizontal slab (S3).

8 is a partially enlarged view of a handle fixing part of a lightweight molding member for fixing to an improved reinforced truss deck plate of the present invention.

The main body 100 may further include a handle fixing part 140 recessed around the fixing key insertion hole 120, and the surface of the handle fixing part 140 may further have an uneven or inclined loop. Can be.

That is, the periphery of the upper surface of the fixing key insertion hole 120 of the main body 100 is engraved in a fan shape, and serves to guide and fix the rotation direction of the fixing key 200. In addition, when the surface of the recessed handle fixing part 140 is rotated to form an unevenness or an inclined loop shown in FIG. 8 (a), the latch fixing part 220 of the fixing key 200 is finally installed. The tension is applied to the latch (D14) and is not released after fastening, and the function of enhancing the unity of the main body 100 and the improved reinforced truss deck plate (D) is enhanced. As another example, as shown in Figure 8 (b) may be processed to form the inclined loop according to the rotation, such as letters or arrow patterns that can inform the operation may have an equivalent function.
