Abstract
Description
The present invention is to solve the structural overdesign of the multi-slab to improve the resistance to the vertical lateral force generated during the construction of the long span in the construction of the underground parking lot, and to ensure structural continuity, which is the lower panel of the slab The T Tee Slab (Triple Tee Slab) is formed so that T-shaped reinforcing ribs are divided into three. By preventing the additional overdesign of the ribs, not only the cost is reduced, but also the worker's workability is improved, and the aesthetics are improved after construction due to the same pitch spacing of the reinforcing ribs when connecting the neighboring slabs. The present invention relates to a TTS slab for underground parking spaces with improved design and multi-slab sharing.
In general, as a PC method for constructing a large-space building that requires a long span such as a large store or a factory, a PRC composite method using a double tee slab, a hollow core slab, etc., is used. Method) and the PC method that is applied to the sub-medium sized building such as underground parking lot, PRC compounding method using Half PC Slab.
This PRC compounding method is a method of converting reinforced concrete ramen (Rahmen) -structured buildings into PCs (Precast Concrete). It is a method of integrating the structure by pouring the overcast concrete on the joint and the upper part of the half slab.
On the other hand, in the case of construction of underground parking lot (construction), the size of the vehicle has recently been increased, and sufficient parking space is required to secure a long parking space. Therefore, when constructing a large space building, the span is generally 7.5 X 7.8. m, 7.5 X 8.0 m, 7.5 X 9.0 m or 8.0 X 8.0 m is required, and the PRC compounding method 10 is constructed in two directions because the slab 20 is designed to be short and construction is not suitable in one direction. to be.
However, when constructing in two directions, PC simple beams and PC girders, which are required structural elements, are increased, resulting in an increase in overall PC volume, making it less competitive than other construction methods. In addition, the increase in the amount of rebars and the increase in construction costs, and in the case of long span (more than 6m) due to structural dynamics and safety issues, additional support should be installed to avoid additional construction costs due to additional cost increase and floor height.
In addition, the HCS method is a prestressed structure that enhances the tensile resistance performance by applying a pre-stressing force to the concrete by using a PS steel wire in which prestress is introduced a lack of tensile resistance performance, which is a weakness of concrete. As a hollow span in the concrete cross-section to reduce the weight of the structure by using a hollow slab to form a long span of 10m or more is mainly applied only to the ground layer structure.
However, HCS requires a separate expensive equipment for securing the minimum thickness and the production of HCS member due to the tension of PS steel wire, causing the unit cost rise, and there is a problem that is difficult to repair when a crack occurs in the member.
On the other hand, the double tee slab method is performed recently. In other words, it is also called DTS method. Double tee slab is formed to install a deep reinforcing rib on the bottom plate, insert a strand in the lower part of the reinforcing rib, and apply a tensile force to form an integral member. Due to this, the central part of the body plate of the double tee slab is raised slightly and is mainly applied to the ground layer structure with a long span of about 10m or more.
However, the double tee slab method described above is difficult to achieve a continuous slab form (both height information) by being seated in the form of a simple beam when applied to a PC beam. In order to improve this problem, the reinforcing ribs are additionally laid or formed to increase the height of the protruding height, which in turn increases the manufacturing cost such as the use of a large number of PC pillars. A problem has occurred.
Therefore, recently, as shown in FIG. 4, in order to improve resistance to the vertical direction between floors of the underground parking lot and to secure structural continuity, multislabs have been constructed, and the multislabs have four reinforcing ribs at the bottom of the panel. Forming at equal intervals to encourage the same vertical resistivity (sharing ratio), but during the installation of equal spacing of the reinforcing ribs, both ends are overdesigned, resulting in an increase in manufacturing cost, manufacturing workability is lowered, shown in FIG. As described above, the construction is connected to abutment ribs on both ends of adjacent multi-slabs so as to be in contact with each other.
The present invention is to solve the above-mentioned problems, the technical gist of the construction of the underground parking lot, the structural ability of the multi-slab to ensure the resistance to the vertical lateral force generated during the long span construction to improve the structure continuity In order to solve the overdesign, this is to form a triple tee slab (Triple Tee Slab) in which the T-shaped reinforcement ribs are tripled at the lower part of the panel of the slab, and the reinforcement ribs are divided by an accurate share ratio. Designed to have the same vertical resistivity compared to the conventional multi-slabs, but prevents additional redesign of reinforcement ribs, thereby reducing costs and improving workability for the worker, and the same pitch spacing of reinforcement ribs when connected to neighboring slabs Overhauling design of multi-slabs' width, which improves aesthetics after construction due to induction In a underground car park construction providing entity S. slabs it is an object.
In order to achieve the object of the present invention, in the underground parking lot PC slab (PC Slab), three
In this case, it is preferable that the reinforcing
As described above, the present invention is to form a T Tee Slab (Triple Tee Slab: Triple Tee Slab) is formed so that the T-shaped reinforcement rib formed in the lower panel of the slab, the reinforcement rib is designed to be divided by the exact sharing ratio of the conventional multi slab It has the same vertical resistivity but prevents the overdesign of additional reinforcing ribs, which improves cost reduction and manufacturing workability, and improves aesthetics after construction by inducing the same pitch spacing of reinforcing ribs when connecting with neighboring slabs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.
1 is a perspective view of a TTS slab according to the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, FIG. 3 is a state diagram of the use of the TTS slab according to the present invention, and FIG. 4 is a side view showing a conventional multi-slab. 5 is a state diagram used in FIG.
First, as shown in Figure 1, the present invention is basically based on the technical idea of the multi-slab of Figure 4, to solve the structural overdesign problem according to the reinforcement rib fabrication of the multi-slab this That is, there is a feature in implementing a triple tee slab.
In other words, in constructing the underground parking lot, the TTS slab is formed with three
That is, as shown in Figure 2, based on the T-shaped reinforcement ribs formed in the center, the left and right T-shaped reinforcement ribs are formed to share the stress acting in the vertical direction by the same sharing width.
This, in turn, maintains the advantages of the multi-slab while improving the structural aesthetics, and is formed to secure industrial competitiveness by reducing manufacturing cost and improving workability due to overdesign.
At this time, if you introduce the advantages of the multi-slab, the resistance to the vertical lateral force compared to the conventional double T slab and half PC slab is improved by more than 15% compared to the conventional structure, the weight-to-weight structure is strengthened, the improved resistance ability is The use of PC pillars compared to the span construction area, other structural members and construction costs are reduced, as well as the construction period is shortened, resulting in improved economic performance, work productivity, and structural resistance.
Accordingly, the TTS slab is preferably formed integrally with the reinforcing
That is, as shown in Figure 3, the reinforcing partition is to improve the resistance acting in the vertical direction in addition to the reinforcing rib.
In addition, the TTS slab of the present invention is characterized in that the reinforcing ribs are connected in a continuous form at the same pitch interval when connected to the neighboring slab, the ceiling aesthetics is improved more in comparison with the conventional multi-slab shown in FIG.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
