As shown in fig. 1-8, the embodiment of the utility model provides a dysmorphism steel beam, this dysmorphism steel beam includes left flange board 1, right flange board 2 and web 3.
With continued reference to FIG. 2, the left flange plate 1 and the right flange plate 2 are arranged in parallel, and the web 3 is perpendicularly connected between the left flange plate 1 and the right flange plate 2. Specifically, the web 3 serves to connect and support the left flange plate 1 and the right flange plate 2, and as shown in fig. 2, the left flange plate 1, the right flange plate 2 and the web 3 are connected to form an i-shaped steel beam.
With continued reference to fig. 3, the width of the left flange plate 1 is linearly widened or narrowed from one end to the other end, and the linearly changing section is at least two sections. The linearly widening section of the left flange plate 1 can withstand a force larger than that of the linearly narrowing section. Specifically, according to the atress characteristic of girder steel, with the broad that the width of the left flange board 1 of the great department of girder steel atress set up, the width that the width of the left flange board 1 of the less department of atress set up is narrower, has not only satisfied the atress demand of girder steel, also to a great extent reduce the steel quantity of left flange board 1, further reduced the cost of girder steel.
In practical use, the right flange plate 2 and the left flange plate 1 are the same in size and shape. Specifically, the size and the shape of the right flange plate 2 and the left flange plate 1 are set to be consistent, so that the strength of the steel beam is guaranteed, the left flange plate 1 and the right flange plate 2 are simpler and more convenient to process, the left flange plate 1 and the right flange plate 2 can be replaced and used mutually, and do not need to be distinguished specially, therefore, the assembly of the steel beam is simpler, and the processing efficiency of the steel beam is higher.
The embodiment of the utility model provides a dysmorphism steel beam, this dysmorphism steel beam include left flange board 1, right flange board 2 and web 3. The left flange plate 1 and the right flange plate 2 are arranged in parallel, and the web 3 is vertically connected between the left flange plate 1 and the right flange plate 2. The width of the left flange plate 1 is linearly widened or narrowed from one end to the other end, and the linear change section is at least two sections. The linearly widening section of the left flange plate 1 can withstand a force larger than that of the linearly narrowing section. The right flange plate 2 and the left flange plate 1 are identical in size and shape. In the actual course of working, with the great department of girder steel atress, for example the width of the left flange board 1 of striding the well position sets up the broad, with the narrower of the width setting at both ends to satisfy the girder steel atress demand and reduced the steel quantity of left flange board by a wide margin simultaneously, and then reduced the cost of girder steel. In addition, the special-shaped steel beam of the embodiment of the application has lower processing difficulty.
With continued reference to fig. 3, the width of the left flange plate 1 widens linearly from one end to 1/2 of the length of the left flange plate 1, and narrows linearly from 1/2 of the length of the left flange plate 1 to the other end of the left flange plate 1. As shown in fig. 1 to 3, a first structural schematic diagram, a left side view and a top view of the steel beam are respectively shown, and the structure of the special-shaped steel beam meets the stress requirement of the simply-supported beam. The simple beam is a supporting structure that the supports at the two ends only provide vertical restraint and do not provide corner restraint. Because the stress of the simply supported beam is relatively simple, the stress at the midspan is the largest, according to the stress characteristic, the width of the left flange plate 1 is linearly widened from one end to 1/2 of the length of the left flange plate 1, and then is linearly narrowed from 1/2 of the length of the left flange plate 1 to the other end of the left flange plate 1, so that the left flange plate 1 can meet the stress requirement, the steel consumption of the left flange plate 1 can be saved, and the cost of the steel beam is further saved.
In practical application, the left flange plate 1 and the right flange plate 2 can be formed by cutting and then splicing the quadrilateral steel plates, as shown in fig. 4, a first cutting schematic diagram of processing raw materials of the left flange plate 1 is shown, as can be seen from fig. 4, a first steel plate 11 and a second steel plate 12 are obtained after cutting the quadrilateral steel plates, and then the left flange plate 1 or the right flange plate 2 can be obtained by splicing the first steel plate 11 and the second steel plate 12. The quadrilateral steel plate can be a newly purchased material, and leftover materials of a construction site can be reused, so that excessive waste materials generated during machining of the left flange plate 1 or the right flange plate 2 are avoided, and the waste materials of the construction site can be reused, so that the cost of the steel beam is reduced, and the overall construction cost is further reduced. Of course, the left flange plate 1 or the right flange plate 2 may be cut from a complete steel plate.
With continued reference to fig. 7, the width of left flange plate 1 narrows linearly from one end to 1/4 of the length of left flange plate 1, widens linearly from 1/4 of the length of left flange plate 1 to 1/2 of the length of left flange plate 1, narrows linearly from 1/2 of the length of left flange plate 1 to 3/4 of the length of left flange plate 1, and widens linearly from 3/4 of the length of left flange plate 1 to the other end of left flange plate 1. As shown in fig. 5 to 7, a first structural schematic diagram, a left side view and a top view of the steel beam are respectively shown, and the structure of the special-shaped steel beam meets the stress requirement of the beam which is just connected at two ends. Because the bending moment at the midspan position of the beam just connected at the two ends is large and a reverse bending point exists, according to the stress characteristics, the width of the left flange plate 1 linearly narrows from one end to 1/4 of the length of the left flange plate 1, linearly widens from 1/4 of the length of the left flange plate 1 to 1/2 of the length of the left flange plate 1, linearly narrows from 1/2 of the length of the left flange plate 1 to 3/4 of the length of the left flange plate 1, and linearly widens from 3/4 of the length of the left flange plate 1 to the other end of the left flange plate 1, so that the left flange plate 1 can meet the stress requirements, the steel consumption of the left flange plate 1 can be saved, and the cost of the steel beam is further saved.
In practical application, the left flange plate 1 and the right flange plate 2 may be formed by cutting and splicing quadrangular steel plates, for example, fig. 4 shows a cutting schematic diagram of raw materials for processing the left flange plate 1, as can be seen from fig. 8, a third steel plate 13 and a fourth steel plate 14 are obtained by cutting the quadrangular steel plates, and then the left flange plate 1 or the right flange plate 2 can be obtained by splicing the two third steel plates 13 and the two fourth steel plates 14. The quadrilateral steel plate can be a newly purchased material, and can also reuse leftover materials of a construction site, so that excessive waste materials generated in the process of machining the left flange plate 1 or the right flange plate 2 are avoided, and the waste materials of the construction site can also be reused, thereby reducing the cost of the steel beam and further reducing the overall construction cost. Of course, the left flange plate 1 or the right flange plate 2 may be cut from a complete steel plate.
In practical application, the width of the narrowest part of the left flange plate 1 is more than or equal to 100 mm. Specifically, when the width of the narrowest part of the left flange plate 1 is equal to 100mm, the left flange plate 1 can meet the stress requirement and is convenient to process, and raw materials required in the process can be saved. When the width of the narrowest portion of left flange plate 1 is greater than 100mm, the machining of left flange plate 1 is easier, but as the width increases, the consumption of material increases, and the machining cost of the steel beam gradually increases, so that 100mm is the optimum value for the width of the narrowest portion of left flange plate 1.
The embodiments in the present specification are described in a progressive manner, and the same or similar parts among the embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments.
