Abstract

A building seismic structure involves placing a reinforcement form a floor slab, or a beam and having the form secured by means of multiple locating members to the floor slab or multiple columns surrounding the floor slab followed with the pouring operation to cover up each and all locating members to complete the seismic structure that is capable of avoiding falling of concrete blocks or collapse of the floor slab that may take place when subject to extremely large force applied externally to the building thus to significantly upgrade the safety and the structural strength of the building.

Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention
The present invention is related to a building seismic structure, and more particularly, to one that effectively avoid possible falling of concrete blocks or collapse of floor slab when the building is subject to extremely large force applied externally thus to significantly upgrade the safety and structural strength of the building.
(b) Description of the Prior Art
Referring to FIG. 1 of the accompanying drawings, typically in a pouring operation for the floor slab, or the beam of a building, moldboards are usually erected and supported below before overlapping the steel bars 11 over the moldboards both laterally and longitudinally and wires 12 are used to tie up and secure the steel bars 11 to complete a layer of steel bar framework. Multiple bricks or cushion blocks 13 are properly placed beneath the steel bars 11 to pour concrete into the framework. Moldboards are removed once the concrete is solidified to conclude the pouring operation.
However, by judging this type of floor slab structure, it is found that the overlapped steel bars tied in check pattern allows steel bars to be bound to the concrete by maintaining the steel bars in the concrete slab, i.e., the weight of the concrete is totally borne by the steel bars significantly showing insufficient structure strength and the incidence of falling concrete blocks or collapse of the floor slab 1 can easily take place when the building is subject to extremely large force externally applied in earthquake or mudflows and landslides to result in injuries and damages to the life and properties of the tenants in the building as illustrated in FIG. 2.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to s provide an improved building seismic structure to effectively avoid hazards of falling concrete blocks or collapse of the floor slab when the building is subject to extremely large force externally applied thus to significantly upgrade the safety and structural strength of the building.
To achieve the purpose, a reinforcement form is first placed below the floor slab or the beam, and multiple locating members are used to secure the form to the floor slab or columns surrounding the floor slab before commencing the pouring operation to wrap up all the locating members.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is related to a building seismic structure involving placement of a reinforcement form below a floor slab and having the form secured by means of multiple locating members to the floor slab or multiple columns surrounding the floor slab, followed with the pouring operation to cover up each and all locating members to complete the seismic structure that is capable of avoiding falling of concrete blocks or collapse of the floor slab that may take place when subject to extremely large force applied externally to the building thus to significantly upgrade the safety and the structural strength of the building.
Referring to FIGS. 3 and 4, a reinforcement form 2 made of metallic material and in a size approximately the same as that of a floor slab 1 is disposed with multiple locating stripes 21. Two locating strips 21 crossing each other are provided in the preferred embodiment as illustrated. Each locating member is related to an S-shaped hook 3 with one end caught in a preset locating hole 22 on the locating strip 21 and another end caught by a steel bar 41 erected to the floor slab 1 or a column 4 surrounding the floor slab 1 before commencing the pouring operation to cover up each and all S-shaped hook 3 to complete an seismic structure as illustrated in FIG. 5
Now referring to FIGS. 6 and 7 for another preferred embodiment of the present invention, a reinforcement form is placed below a beam 5. The reinforcement form is made of metallic material and is related to a ␣-shaped fillister 2′ to cover up where below the beam 5. Multiple locating strips 21′ are disposed in the fillister 2′. The locating stripe 21′ is related to a C-shaped steel while each locating member is related to the S-shaped hook 3. One end of the S-shaped hook 3 is caught in a locating hole 22's present on the locating strip 21′ and another end of the S-shaped hook 3 catches the floor slab 1 or two steel bars 11, 41 of one of the columns 4 surrounding the floor slab 1 before commencing the pouring operation to wrap up each and all S-shape hooks 3 to complete the seismic structure as illustrated in FIG. 8. Furthermore, a lip 23′ each extends along the top edge of the fillister 2′ towards its both sides to define a flushed plane for bearing the floor slab to improve the appearance of the floor slab.
The prevent invention provides an improved structure of a building seismic structure, and the application for a utility patent is duly filed accordingly. However, it is to be noted that the preferred embodiments disclosed in the specification and the accompanying drawings are not limiting the present invention; and that any construction, installation, or characteristics that is same or similar to that of the present invention should fall within the scope of the purposes and claims of the present invention.
