The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
As shown in fig. 1 to 3, a transfer beam 100 of an embodiment of the present invention includes a base plate 1, a first stiffener 2, a plurality of second stiffeners 3, and a connecting member 4.
The first reinforcing rib 2 is provided on the base plate 1, and the first reinforcing rib 2 extends in the longitudinal direction (the left-right direction as viewed in fig. 1) of the base plate 1. The plurality of second reinforcing ribs 3 are respectively arranged on the bottom plate 1, the plurality of second reinforcing ribs 3 are arranged at intervals in the length direction of the bottom plate 1, the second reinforcing ribs 3 and the first reinforcing ribs 2 are arranged in a crossed mode to form a plurality of filling cavities 11, and the filling cavities 11 are suitable for being filled with fillers. A plurality of connectors 4 are located within the fill cavity 11.
Specifically, the lower end of a first reinforcing rib 2 is connected with the upper end of a bottom plate 1, the lower end of a second reinforcing rib 3 is connected with the upper end of the bottom plate 1, the first reinforcing rib 2 extends along the left-right direction, the second reinforcing rib 3 extends along the front-back direction, the plurality of second reinforcing ribs 3 and the first reinforcing rib 2 are arranged in a crossed mode to enable the bottom plate 1 to form a plurality of filling cavities 11 in the left-right direction, the lower end of a connecting piece 4 is connected with the upper end of the bottom plate 1, and the height of the connecting piece 4 is lower than that of the first reinforcing rib 2 in the up-down direction of the bottom plate 1, so that the connecting piece 4 is located in the filling cavities 11.
Optionally, the front end of the first reinforcing rib 2 is connected with the second reinforcing rib 3, and the rear end of the first reinforcing rib 2 is also connected with the second reinforcing rib 3, so that the bottom plate 1 forms a plurality of filling cavities 11 in the front-rear direction, and the connection of the first reinforcing rib 2 and the second reinforcing rib 3 with the bottom plate 1 can prevent the bottom plate 1 from buckling and improve the strength of the bottom plate 1.
Optionally, a plurality of connecting pieces 4 are arranged at intervals in the front-back direction and the left-right direction of the bottom plate 1, the connecting pieces 4 are located in the filling cavity 11, the filling cavity 11 is filled with filler, and through the arrangement of the connecting pieces 4, the bottom plate 1 and the filler can be prevented from being separated when the transfer beam 100 is subjected to external force, and the connecting pieces 4 can enable the bottom plate 1 and the filler to be integrated to jointly bear the external force, so that the structural strength of the transfer beam 100 is improved.
Alternatively, by providing the bottom plate 1 at the bottom of the transfer beam 100, the bottom plate 1 and the filler form a combined action, the stress performance is more excellent, the required section height is lower, and thus the weight of the transfer beam 100 can be further reduced, compared to the transfer beam 100 of pure concrete in the related art.
According to the conversion beam 100 provided by the embodiment of the invention, the bottom plate 1 is arranged as the bottom bearing piece of the conversion beam 100, the bottom plate 1 and the filler are integrated by arranging the connecting piece 4, so that the bottom plate 1 and the filler are stressed together, and the rigidity of the bottom plate 1 is enhanced by the first reinforcing rib 2 and the second reinforcing rib 3, so that when the conversion beam 100 is subjected to a vertical load, the stress can be transmitted by the first reinforcing rib 2 and the second reinforcing rib 3, the bearing capacity of the bottom plate 1 on the load is improved, and further the bearing capacity of the conversion beam 100 on the load is improved.
For example, the number of the first reinforcing ribs 2 may be set to be plural, such as one, two, three, the plural first reinforcing ribs 2 are arranged at intervals in the front-rear direction of the base plate 1, and the plural first reinforcing ribs 2 are arranged to intersect with the plural second reinforcing ribs, so that the stability and strength of the base plate 1 can be improved, and further the stability and strength of the transfer beam 100 can be improved.
For example, the second reinforcing ribs 3 are arranged at intervals in the left-right direction, and may be arranged at even intervals, so that the stress of the plurality of second reinforcing ribs 3 is more balanced, or a plurality of second reinforcing ribs 3 are arranged at places with intensive stress according to different bearing conditions of vertical load, so as to improve the bearing of the second reinforcing ribs 3 on the stress, improve the bearing capacity of the bottom plate 1, and further improve the bearing capacity of the transfer beam 100.
For example, the bottom plate 1, the first reinforcing ribs 2, the second reinforcing ribs 3, and the connecting members 4 are integrally formed, so that the construction efficiency of the transfer beam 100 can be improved and the construction period can be shortened.
For example, the first reinforcing rib 2 and the second reinforcing rib 3 can be welded on the bottom plate 1, and the connection positions of the first reinforcing rib 2 and the second reinforcing rib 3 with the bottom plate 1 can be flexibly adjusted according to different stresses at different positions of the transfer beam 100, so that the structural diversity of the transfer beam 100 is improved.
For example, the connecting members 4 may be welded to the bottom plate 1, and the filler and the bottom plate 1 may be integrated by the connecting members 4, and the connecting members 4 may be uniformly arranged on the bottom plate 1, or a plurality of connecting members 4 may be provided at a location where the stress is concentrated, so as to improve the stress capability of the location where the stress is concentrated, and further improve the structural strength of the transfer beam 100.
For example, the connection 4 may be provided as a peg, T-steel connection. The base plate 1 may be a steel plate.
In some embodiments, the bottom plate 1 comprises a first supporting portion 12, a second supporting portion 13 and a third supporting portion 14 which are sequentially connected in the length direction of the bottom plate 1, the filler comprises a first filler 5 and a second filler 6, the first supporting portion 12 and the third supporting portion 14 are filled with the first filler 5, and the second supporting portion 13 is filled with the second filler 6.
Specifically, the first support portion 12 is located at the left end of the bottom plate 1, the second support portion 13 is located at the right end of the bottom plate 1, and the second support portion 13 is located between the first support portion 12 and the third support portion 14, so that the bottom plate 1, the first reinforcing rib 2, the second reinforcing rib 3, the connecting member 4, and the filler are integrally filled to form the transfer beam 100.
For example, the first filler 5 is fiber cement-based composite concrete, the second filler 6 is concrete, and because the fiber cement-based composite concrete has high ductility and strict crack width control, while ordinary concrete is easy to crack under stress, and the crack width is not easy to control, which affects the structural durability of the transfer beam 100, in the embodiment of the invention, different types of concrete can be filled in different parts of the bottom plate 1 according to different bearing positions of the transfer beam 100, so as to improve the strength and the deformability of the transfer beam 100.
In the embodiment of the invention, as the fillers poured on the first supporting part 12 and the third supporting part 14 bear negative bending moment and need good crack control capability, the fiber cement-based composite concrete is poured on the first supporting part 12 and the third supporting part 14, so that the first supporting part 12 and the third supporting part 14 have better crack control capability and deformation capability compared with the second supporting part 13, deformation can be better resisted, and the durability of the areas of the first supporting part 12 and the third supporting part 14 of the transfer beam 100 is improved. Compared with the conventional reinforced concrete conversion beam in the related art, the amount of the filler can be reduced by pouring the fiber cement-based composite concrete on the first supporting portion 12 and the third supporting portion 14, so that the weight of the conversion beam 100 is reduced.
Alternatively, by casting fiber cement-based composite concrete on the first support part 12 and the third support part 14, casting concrete on the second support part 13, and combining the arrangement of the first reinforcing rib 2, the second reinforcing rib 3 and the connecting member 4, the height of the transfer beam 100 in the embodiment of the present invention is reduced compared to the height of the transfer beam 100 in the related art under the same bearing capacity, thereby reducing the height of the whole building.
Alternatively, the construction cost of the transfer beam 100 may be reduced while the structural strength is ensured by pouring concrete through the second supporting portion 13, and the performance of different types of concrete is fully exerted by pouring different concrete at different positions of the first supporting portion 12, the second supporting portion 13 and the third supporting portion 14, thereby improving the structural strength of the transfer beam 100.
For example, the second supporting portion 13 may be poured with fiber cement-based composite concrete, and the concrete grade filled in the first supporting portion 12, the second supporting portion 13 and the third supporting portion 14 cannot be less than C30.
The setting of connecting piece 4 can be so that concrete and bottom plate 1 become whole, avoids when the atress of transfer beam 100, and the concrete takes place to separate with bottom plate 1, through the setting of connecting piece 4 for bottom plate 1 becomes whole with the concrete, and the coordination is out of shape, common atress.
For example, by setting the dimensions of the first support 12, the second support 13, and the third support 14 to be the same in the left-right direction of the bottom plate 1, the forces applied to the first support 12, the second support 13, and the third support 14 can be relatively equalized.
In some embodiments, the thickness of the first support portion 12 is gradually reduced in a direction away from the second support portion 13 in the length direction of the base plate 1, and the thickness of the third support portion 14 is gradually reduced in a direction away from the second support portion 13 in the length direction of the base plate 1.
Specifically, the thickness of the first supporting portion 12 is smaller than that of the second supporting portion 13, the thickness of the third supporting portion 14 is smaller than that of the second supporting portion 13, the thickness of the first supporting portion 12 gradually increases from left to right, the thickness of the second supporting portion 13 gradually increases from left to right to a maximum thickness and then gradually decreases, and the thickness of the third supporting portion 14 gradually decreases from left to right.
Optionally, by increasing the thickness of the second supporting portion 13, the tensile property of the bottom plate 1 is fully utilized, and the capability of the second supporting portion 13 to resist the vertical load above is improved, so that when the second supporting portion 13 is connected with other structures, the load capacity of the second supporting portion 13 is stronger, and the load capacity of the transfer beam 100 is improved.
For example, the increasing width of the thickness of the first support 12 gradually increases from left to right and the increasing width of the thickness of the third support 14 gradually increases from right to left are the same, and the first support 12 and the third support 14 are symmetrically stressed by the same increasing width, so that the stability of the first support 12 and the third support 14 is improved, and the structural stability of the transfer beam 100 is further improved.
For example, the increase in the thickness of the second support portion 13 gradually increases from left to right and the increase in the thickness of the second support portion 13 gradually increases from right to left are set to be the same, so that the left and right sides of the second support portion 13 are uniformly stressed. The increasing amplitude of the thickness of the second supporting portion 13 gradually increasing from left to right is set to be different from the increasing amplitude of the thickness of the first supporting portion 12 gradually increasing from left to right, so that the loading capacity of the second supporting portion 13 when the second supporting portion is subjected to the vertical load is stronger, and the second supporting portion 13 can provide stable supporting effect for other structures above.
For example, the maximum thickness of the second support portion 13 may be 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, different thickness values may be set according to different vertical loads, and the design may be performed in a wide range according to the sizes of the first, second, and third support portions 12, 13, and 14 in the left-right direction so that the structural strength of the floor panel 1 can satisfy the design requirements.
For example, the thickness of the first support part 12 may have a value of 20mm, 25mm, 30mm, 40mm, 50 mm.
In some embodiments, the outer contour of the longitudinal section of the base plate 1 is an arc-shaped plate.
Specifically, the bottom plate 1 is designed to be an arc-shaped plate, so that the stress performance of the transfer beam 100 is better, the force of the upper load is transmitted to the support columns on the two sides, and the spanning capacity of the transfer beam 100 is improved.
Optionally, the arch plate is arranged so that when the bottom plate 1 is stressed, the left end and the right end of the arch plate are respectively used as supporting points to disperse the stress, thereby improving the strength of the bottom plate 1. The arched plate can increase the space utilization and make the transfer beam 100 more beautiful.
In some embodiments, the arc of the first support 12 is the same or different than the arc of the third support 14.
Alternatively, the radian of the first support portion 12 and the radian of the third support portion 14 may be determined according to the rise and the span of the arch of the bottom plate 1, and the radian of the first support portion 12 is set to be the same as the radian of the third support portion 14, so that the stress of the first support portion 12 and the stress of the third support portion 14 are balanced, and the structural stability of the first support portion 12 and the structural stability of the third support portion 14 are improved. The radian of the first support part 12 is set to be different from the radian of the third support part 14 so that the transfer beam 100 is suitable for different building structures.
In some embodiments, a plurality of second reinforcing ribs 3 are arranged parallel to each other or extensions of the plurality of second reinforcing ribs 3 are arranged to intersect.
Specifically, the second reinforcing ribs 3 are arranged in parallel in the left-right direction, and the second reinforcing ribs 3 extend in the front-rear direction.
Optionally, the plurality of second reinforcing ribs 3 are arranged in parallel, and the plurality of second reinforcing ribs 3 are arranged perpendicular to the first reinforcing ribs 2, so that the second reinforcing ribs 3 and the first reinforcing ribs 2 form perpendicular intersections, and when an external force is applied to the transfer beam 100, the stress can be resolved more evenly, thereby improving the stability of the transfer beam 100.
For example, the plurality of second reinforcing ribs 3 are arranged in parallel, but the plurality of second reinforcing ribs 3 are not perpendicular to the first reinforcing ribs 2, or the plurality of second reinforcing ribs 3 are arranged in non-parallel, or the angles between the plurality of second reinforcing ribs 3 and the first reinforcing ribs 2 are arranged regularly, so that the stress structure of the transfer beam 100 is changed, and the application range of the transfer beam 100 is improved.
In some embodiments, the second strengthening rib 3 and the first strengthening rib 2 are at the same height on the base plate 1.
Optionally, the first stiffener 2 and the second stiffener 3 have the same size in the vertical direction, so that when the transfer beam 100 is subjected to an external force, the first stiffener 2 and the second stiffener 3 can be simultaneously stressed, the bearing capacity of the transfer beam 100 is improved, and the situation that only the first stiffener 2 or only the second stiffener 3 is stressed is avoided, and the bearing capacity of the transfer beam 100 is reduced.
In some embodiments, one end of the second reinforcing rib 3 is connected to one end of the bottom plate 1 in the width direction, and the other end of the second reinforcing rib 3 is connected to the other end of the bottom plate 1 in the width direction.

Specifically, the front end of the second reinforcing rib 3 is flush with the front end of the bottom plate 1, the rear end of the second reinforcing rib 3 is flush with the rear end of the bottom plate 1, so that the front end of the second reinforcing rib 3 can fix the front end of the bottom plate 1, and the rear end of the second reinforcing rib 3 can fix the rear end of the bottom plate 1, so that when the bottom plate 1 is subjected to an external force, the probability of buckling of the front end and the rear end of the bottom plate 1 can be reduced through the fixing effect of the second reinforcing rib 3 on the front end and the rear end of the bottom plate 1, the rigidity of the bottom plate 1 is improved, and the rigidity of the transfer beam 100 is further improved.
