Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The present invention will be further described with reference to the following specific embodiments and accompanying drawings.
Example 1:
the formwork-dismantling-free steel bar truss floor bearing plate comprises a steel bar truss 1 and a bottom formwork 2; the steel bar truss 1 is fixedly connected into a whole by welding an upper chord steel bar 101, a lower chord steel bar 102 and a web member steel bar 103; the lower part of the lower chord steel bar 102 of the steel bar truss 1 is fixedly provided with a square tube, and the square tube is connected with the bottom template 2 through a tapping screw 3.
In this embodiment the square pipe is short square pipe 4, and the lower chord reinforcing bar 102 lower part of 1 both sides of steel bar truss is fixed respectively and is provided with a section of short square pipe 4, and the interval is 400mm between two short square pipes 4.
This embodiment the counter bore has been seted up to 2 bottoms of bed plate, self-tapping screw 3 sinks the counter bore from 2 bottoms of bed plate and is connected bed plate 2 and square pipe, and self-tapping screw 3 sinks 2 faces of bed plate and is not less than 1mm, and self-tapping screw 3 is fixed bed plate 2 from 2 bottoms of bed plate on square pipe, is connected fixedly with steel bar truss 1.
In this embodiment, the square pipe is welded with the bottom of the lower chord steel bar 102, so that the connection is more stable.
In this embodiment, the bottom form 2 is a fiber cement board.
The working principle is as follows: firstly, welding a short square tube 4 or a through long square tube 5 with lower chord steel bars 102 on two sides of a steel bar truss 1, then punching a hole on the bottom surface of a fiber cement plate and making a counter bore to ensure that a self-tapping screw 3 can sink into the plate surface to be not less than 1mm, and finally fixing the fiber cement plate to the bottom of the short square tube 4 or the through long square tube 5 by using the self-tapping screw 3 according to the design requirement to be connected with the steel bar truss 1 into a whole. Then determining the fixed distance between the fiber cement plate and the steel bar truss 1: according to the connection mode, the hanging force of a single self-tapping screw 3 can reach 2000N, and the breaking strength of the fiber cement board is not less than 16MPa and far higher than 2000N, which can not be considered. In the concrete pouring process, the total bearing capacity of the floor bearing plate is the dead weight of constructors (160 kg for 2 persons per square meter), the concrete dead weight (about 600 kg/square meter considering the large local thickness calculated according to the thickness of 200 mm), the dead weight of the steel bar truss floor bearing plate (52kg), and the product is multiplied by the safety factor of 1.2, namely the floor load per square meter is 9744N and 9744/2000 is approximately equal to 5, namely the bearing capacity requirement can be met by not less than 5 hanging points per square meter. Calculate for 200mm according to adjacent horizontal steel bar truss interval L, even the fixed spacing is 1m, every square meter also has 10 fixed points at least, satisfies the bearing capacity requirement completely, consequently the utility model discloses an application environment is good.
