Should be understood that, accompanying drawing is the illustrative and unrestricted scope of the present invention be defined by the following claims.Shown embodiment achieves various aspects of the present invention and object.Should be understood that, can not be clearly shown that in single figure each element of the present invention and in, and thus, multiple accompanying drawing is provided to more clearly illustrate each details of the present invention respectively.Similarly, not each embodiment needs to realize all advantages of the present invention.
Detailed description of the invention
Exemplary prefabricated structural flooring system, composite floor panel, compound crossbeam, joint and method for the formation of each be discussed, to enable those skilled in the art to put into practice the present invention now with reference to the Reference numeral provided wherein.Accompanying drawing and illustrate it is the scope that the example of the various aspects of disclosed example and not intended to be narrow claims.
When compared with conventional system, hereafter disclosed example can reduce the weight of floor system.Such as, the Concrete Double T-shaped system every square feet with the routine of similar span and loading condition will than disclosing example great about 100% herein.Other structural element such as concrete beam used together with two T-shaped system and concrete column are also heavier than the column used together with the present invention a lot.The weight of the increase of two T-shaped floor system needs larger ground and foundation wall.This is restrictive for higher structure and the structure in the poor region of bearing capacity of soil.
The vertical leg of two T-shaped floor panel or wall are solid and can not allow mechanical parts, pipeline or electric by T-shaped part, thus increase the size of floor to floor because all facilities need to run below flooring structure.Opening in the trunk wall (stem wall) of native system allow mechanical parts, electrically and pipeline through this structure, thus do not need these elements are run below flooring structure.
Due to distance between girders (compared to 4 feet or 5 feet of the leg of two T-shaped system, it is 8 feet, usual interval in center) comparatively far away, therefore native system is also allowed and is being arranged the larger flexibility in sheet material perforation (opening through floor board).
Two T-shaped system is assembled by the welded plate be embedded in each parts, and must be carried in concrete or masonry structure.Current system is bolted in lighter steel work, and this makes it can use in middle-high building structure.
Conventional steel and concrete composite construction also have the some problem alleviated by the present invention.The framework of conventional composite floor board is very labour-intensive at the scene.After installing the column being used for conventional framed floor, all the other materials for conventional system are installed separately, and the concrete comprising crossbeam, joist, metal carrier, nelson stud, reinforcement, edge covers and pour into a mould.Due to the prefabricated character of native system, therefore this assembling spends the much longer time than the present invention.Use the present invention, craftsman can take floor and complete construction with short a lot of time limit, this means the total engineering time shortened.
Due to the computational methods performed conventional composite floor board, the concrete below the top being arranged in the groove of board uses in composite material cross section, but still facilitates the concrete weight in building and the cost for this material.By floor panels panel, present system eliminates the demand to metal carrier.Which eliminate required material in place for the welding of steel board and labour.
In normal steel work, be the total weight that steel frame component must carry the water-bearing concreae without any concrete strength to the governing factor of the size of steel beam column.In the present invention, girder steel by concrete be wet while supported completely by template.This itself reduces the size of girder steel and does not need beam to carry out pre-warping, and this is because beam does not need to support the weight of water-bearing concreae.
In addition, in normal steel work, beam is aimed at, and makes crossbeam concordant with the top of joist.Doing like this is because metal carrier is disposed on joist and crossbeam, and described board is used as the template of concrete plate.When calculating the cross section property of this system, the distance from the top of girder steel to concrete middle part is one of maximum factor.Concrete trunk wall to be arranged between girder steel and concrete plate and to remove steel board by the present invention, thus increases the distance of the center line from the top of girder steel to concrete plate and generate composite material cross section.Thus, the bearing strength of prefabricated panel system and span capability increase greatly.Compared with the cast of routine system in place, this floor system eliminates a large amount of steel and concrete material.
When describing precast construction floor system of the present invention, showing multiple views of floor panel and crossbeam, comprise the view of its part and show its in-built sectional view.For the sake of clarity, not each structure of panel or crossbeam is all labeled about each accompanying drawing or discusses, but should be understood to be the part of panel or crossbeam.
