Description

MODULAR BUILDING CONNECTOR SYSTEM

TECHNICAL FIELD

This new invention is about the system of prefab construction, and is more particularly described as the modular building connector system. The connectors are used to inter-link building parts for easy assembling and disassembling of columns, beams , panels , floor slabs, stairs, fences, and the likes .

BACKGROUND ART

The typical system of construction is one by which buildings are constructed on site, using steel reάiforced concrete and hollow blocks. Though widely accepted, this system is complicated and requires highly skilled laborin the erection of horizontal and vertical structures. Furthermore, it uses excessive mortar or cement materials between parts and between the joints of ho low blocks.

DISCLOSURE OF THE INVENTION

With the present invention, the building or the whole structure can be assemble by means of concrete connectors and the whole building can also be relocated, meaning it can be disassembled and then reassembled. The other advantage is that ft allows for expansion, that is, by this system, there is no problem in adding add Bional floors. And for one thing, it is capable of being integrated into the prefab construction system, specially in the mass production of standard units in factories where there are quality control procedures, thus achieving products free from defects and unaffected by weather conditions. It also allows construction time to be shortened, and since it does not require highly skflled labor, It achieves cost economy.

In the final analysis, the system makes for an improved system of construction while addressing the fundamental concerns about cost, efficiency, time span, and other problems.

As discussed above, this new invention is a breakthrough in the construction industry, the general purpose of which being to provide a solution to its existing problems, whϊe providing many advantages and eliminating several disadvantages.

Broadly outlined are the important features of the invention, which allow for a better understanding of the detailed description and betterappreciation of the invention's contrbution to the construction industry. It is to be understood, however, that the invention is not limited in its application by the designs and arrangement illustrated or detailed here, as it is capable of being designed similarly and integrate with other parts and different embodiments. The phraseology and terminology employed here are for the purposes of description and should not be regarded as limiting. Those who are knowledgeable in the art will appreciate that the conception upon which these disclosures are based may be utiized as basis for designing different structural connectors under different methods, arrangements and system.

Such being the case, it is important that the claim for this invention be regarded as inc hiding equivalent modular building connector systems that do not depart from the spirit and scope of this invention.

The main objective therefore of this new invention is to provide a new idea and a breakthrough fri the bufldhg system, that utilized interconnection of concrete structural components that are fixed on connectors for easy assembling and disassembling. The said structural components may be columns, beams, panels, floor slabs, stairs, fences and the likes.

One objective of this invention is to provide a modular building system, which is relocatable, because it can be disassembled and then reassembled. The other objective is to provide a system, which is expandable in order to allow for expansion and addition of extra floors.

Stii, another objective is to integrate the use of prefab and pre-cast concrete construction.

A further object is to integrate the use of structural steel construction. With the following advantages: mass production of standard units, savings in terms of shortened construction time, savings in terms of labor cost, may use unskilled labor, better qualfty and stronger concrete, and freedom from defects and from being affected by weather. These objectives, along with the various flexibility features, which characterized the invention, are pointed out with particularity in the claims annexed to and forming part of this disclosure.

The concrete connector consist of generally steel body having a stair tike configuration serving as main connectors. The said connectors are provided with holes, which are distributed along the opposed sides, where boBs can be inserted for connection. The connector includes flanges where the anchor studs are fixed so that the connector can be joined together with reinforced steel bars and then cast into concrete in setting up to produce modular buflding components. The connectors are fixed to the buϊding components to be connected to other building components, which are also fixed on connectors.

The concrete connectors integrate e specially designed, modular columns and beams exclusively for its own use. The beam having an end portion similar to the column's extended side stair like configuration providing a constructional feature that will allow installing additional structural columns and beams for multi-leveling.

For better understanding of the invention, its operating advantages and the specific objectives attained by its use, reference should be made to the accompanying drawings and descriptive matters which illustrate the detailed description of the invention.

Said female rabbet connector 12 having a stair like configuration is provided with a plurality of spacedly disposed apertures 13 found on the opposed sides thereof.

Said column A which has footing configured similarty to the female rabbet connector 12 is provided in such a way to accommodate a secure attachment of said connector 12. In Figure 5, there is shown a male double rabbet connector 14 having a stair like configuration also provided wih a plurality of spacedly disposed apertures 13 found on the opposed sides thereof. Said male double rabbet connector 14 generafly secured to the end portion of the precast horizontal column B or beam can be mated to the female rabbet connector 12 disposed on the upstanding precast column A. The connection is made sturdy and secured by inserting on the corresponding apertures 13 any suitable securing means but preferably of bolts inserted thereto. It is to be noted that t e end portion of the present horizontal column B or beam is configured simiar to the male double rabbet connector 14 in such a way to accommodate a secure attachment of the said connector 14 thereof. A corbel connector 15 having generally rectangular H-shaped body configuration is provided with a pluraBty of apertures 13B proximate to its edges and is securedry attached to the topmost extended portions of the upstanding precast column A providing a constructional feature that will allow installing additional upstanding and horizontal precast or prefabricated columns and beams for multi-leveling.
