Abstract
The invention relates to a joist. The joist is box-shaped or tank-shaped. The upper surface of the joist is matched with a steel framework of a floor, and is provided with connecting holes. The joist is fastened below the steel framework in a bolt manner or a welding manner. The two ends of the joist are provided with end plates and horizontal reinforcing bars. The joist overcomes technical difficulties, namely jointing between structured floors, and reinforcement and elevating of floors, and can be used as positioning, supporting and connecting auxiliary devices.
Description
Technical field
The present invention relates to technical field of buildings, be specifically related to a kind of joist that improves floor strength, auxiliary floor splicing, improves FFL.
Background technology
In existing building construction process, there is the shortcoming that insufficient strength, security reliability are not high in floor and floor splicing, sometimes needs to increase thickness and the intensity of floor, if steel plate or concrete slab are thickeied to improve thickness and intensity, often cost is higher, and very heavy.
Summary of the invention
The object of the invention is in order to overcome the deficiencies in the prior art, a kind of a kind of joist of being convenient to connect, can improve outage degree in floor strength, auxiliary floor splicing, lifting floor is provided.
The present invention is achieved by the following technical programs:
A kind of joist, described joist is box-shaped or flute profile, adopt steel plate or channel-section steel to make, the upper surface of described joist and the steel frame of floor match, at upper surface, be provided with connecting hole, described joist is fastened on the steel frame below of floor by the mode of bolt or welding, the two ends of described joist are provided with end plate, and described end plate is provided with for be connected the connecting hole of the standard module of use with other member.
Further, the two ends of described joist are welded with the beard muscle that connects use.
Technique effect of the present invention is as follows:
The present invention adopts box-shaped or the bathtub construction of two ends band connecting hole and beard muscle, can assemble rapidly with underfloor surface, effectively auxiliary floor and floor splicing, can significantly improve the intensity of floor and floor junction, make floor splice more rapidly, more safe and reliable.At some special occasions, adopt joist of the present invention to promote and hug the height of plate, the interior sky of increase floor.The connecting hole at two ends of the present invention and beard muscle, make floor be connected with other member more quick, intensity is higher.
The present invention has solved the splicing of structure floor and floor, the technical barrier that floor self is strengthened and raise well, can be used as location, support and auxiliary connecting device, significantly improves speed of application and security reliability.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is top view of the present invention.
In accompanying drawing: 1-joist, 2-end plate, 3-beard muscle, 4-connecting hole.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of joist 1, described joist 1 is box-shaped or flute profile, adopts steel plate or channel-section steel to be welded.When using channel-section steel to make, the opening of channel-section steel should be down, and it is bottom-up, and is drilled with connecting hole 4, and the size of described connecting hole 4 and position should match with the steel frame of the floor on joist 1 top, to facilitate assembling of floor and joist 1.Joist 1 can mode with bolts or welding be fastened on below the steel frame of floor.When the splicing of floor and floor, the length of joist 1 should be designed to the width sum of two floors, and making two floor amalgamations is an integral body, improves the intensity of floor and floor junction, make floor splice more rapidly, more safe and reliable.
The two ends of joist 1 are provided with end plate 2, and described end plate 2 is provided with for be connected the connecting hole 4 of the standard module of use with other member.The two ends of joist 1 are also welded with the beard muscle 3 that connects use, and described beard muscle 3 adopts fine steel rib or steel wire to make, and is designed to the shape of head band crotch.When the floor after supporting plate being installed being connected with other member, can be with bolts, beard muscle 3 connects, make to connect more quick, intensity is higher.
Above embodiment is explanation of the invention, and non-limiting, and more than just part is given an example.Should be noted that, concerning the technician of the industry, simple transformation and the improvement according to basic principle of the present invention and structure, carried out, include within protection scope of the present invention.
Claims (2)
1. a joist, it is characterized in that: described joist is box-shaped or flute profile, adopt steel plate or channel-section steel to make, the upper surface of described joist and the steel frame of floor match, at upper surface, be provided with connecting hole, described joist is fastened on the steel frame below of floor by the mode of bolt or welding, the two ends of described joist are provided with end plate, and described end plate is provided with for be connected the connecting hole of the standard module of use with other member.
2. a kind of joist according to claim 1, is characterized in that: the two ends of described joist are welded with the beard muscle that connects use.
