Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction, in particular to a beam combination structure used for floor slabs. Background Art
[0002] At present, the commonly used floor beam structure arrangements in reinforced concrete structures include primary and secondary beam structures, cross-beam structures, etc. For large-span floors such as lecture halls and gymnasiums, when the primary and secondary beam structure is adopted, the main beam needs to bear the load transmitted from the secondary beam, and the main beam span is relatively large, so the cross section of the main beam is often relatively large. The cross-beam arrangement can transfer the load to the surrounding beams in both directions. The cross-beam is more balanced in force, which can reduce the cross section of the beam, and is also beautiful and can reduce the project cost. Therefore, the cross-beam is mostly used in large-span floors.
[0003] The existing lattice beam arrangement methods mainly include orthogonal arrangement and oblique arrangement. The lattice beams of these two methods can generally be regarded as simply supported beams hinged at both ends. The lattice beam has a large span, which increases the requirements for the peripheral frame beams, so that the cross-sectional height of the peripheral frame beams is often consistent with the lattice beam, and the design bearing capacity of the peripheral frame beams is often smaller than that of the lattice beams, which leads to unnecessary waste of materials. In addition, the existing lattice beams are mostly single-span structures. In actual projects, the bearing capacity is usually increased by increasing the height of the lattice beams, which increases the project investment. Summary of the invention
[0004] In view of this, the utility model proposes a beam combination structure for floor slabs. The utility model improves the bearing capacity of floor slab beams by changing the cross beam from a single span to a three-span structure, reduces the height requirements for the cross beams and the height requirements for the external frame beams, and reduces the project cost.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The beam combination structure for floor slabs of the utility model comprises a frame beam and a cross beam, wherein the frame beam comprises a first beam connecting adjacent beam columns together, and a plurality of the first beams form an outer frame beam with a rectangular structure; a central column is provided at the central position of each side of the outer frame beam, and the frame beam further comprises a second beam connecting two adjacent central columns together, and a plurality of the second beams form an inner frame beam with a diamond structure, and the inner frame beam and the outer frame beam form four triangular areas;
[0007] The cross-shaped beam includes a cross-shaped portion which is arranged in the inner frame beam and is concentric with the inner frame beam, wherein the third beam of the cross-shaped portion is parallel to a pair of sides of the inner frame beam, and the fourth beam is parallel to another pair of sides of the inner frame beam; the cross-shaped beam also includes a first connecting beam which corresponds one-to-one to the end of the third beam and a second connecting beam which corresponds one-to-one to the end of the fourth beam, and the first connecting beam and the second connecting beam are both located in the triangular area corresponding to them.
[0008] The beneficial effects are as follows: the utility model can transform the cross beam into a three-span continuous beam by using the inner frame beam, which includes one span inside the inner frame beam and two spans located in the triangular areas on both sides, greatly improving the bearing capacity, thereby reducing the design height of the cross beam on the basis of meeting the design bearing capacity, and reducing the engineering cost; in addition, since the cross beam of the utility model has three spans, the single span of the cross beam is greatly reduced, thereby reducing the requirements for the outer frame beam, further reducing the height of the outer frame beam, and saving materials. The utility model uses the inner frame beam to connect the central columns together, thereby improving the lateral stiffness of the frame beam. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0015] like Figure 1 As shown, the beam combination structure for floor slabs described in the utility model includes a frame beam and a cross beam, the frame beam includes a first beam 2 connecting adjacent beam columns 1 together, and a plurality of first beams 2 form an outer frame beam with a rectangular structure; a central column 3 is provided at the central position of each side of the outer frame beam, the frame beam also includes a second beam 4 connecting two adjacent central columns 3 together, and four second beams 4 form an inner frame beam with a diamond structure, and the inner frame beam and the outer frame beam form four triangular areas Q1 and one diamond area Q2;
[0016] The cross-shaped beam includes a cross-shaped portion 5 which is arranged in the inner frame beam and is concentric with the inner frame beam, the third beam 5.1 of the cross-shaped portion 5 is parallel to a pair of sides of the inner frame beam, the fourth beam 5.2 of the cross-shaped portion 5 is parallel to another pair of sides of the inner frame beam, and the ends of the third beam 5.1 and the fourth beam 5.2 are both connected to the inner frame beam; the cross-shaped beam also includes a first connecting beam 6 which corresponds one-to-one to the end of the third beam 5.1 and a second connecting beam 7 which corresponds one-to-one to the end of the fourth beam 5.2, the first connecting beam 6 and the second connecting beam 7 are both located in the corresponding triangular area Q1, the two ends of the first connecting beam 6 are respectively connected to the first beam 2 and the second beam 4 of the triangular area Q1, and the second connecting beam 7 is connected to the first beam 2 and the second beam 4 of the triangular area Q1.
[0017] Combination Figure 1 It can be seen that the utility model adds an inner frame beam of a diamond structure in the outer frame beam of a rectangular structure.
