Description

Technical Field

[0001] This utility model relates to the field of building construction, and specifically refers to a hollow connecting beam structure that can be internally fitted with stirrups. Background Technology

[0002] In super high-rise or long-span buildings, structural design is quite challenging. Traditional pure concrete structures are difficult to apply to super high-rise and extremely long-span structures. Steel-concrete composite structures are a structural form that is gradually being widely used in high-rise buildings. However, in existing technologies, the internal cross-section of the steel profile is large, making it difficult to tie the stirrups in the concrete beams and simultaneously tie multiple stirrups inside and outside the steel profile. Therefore, measures are needed to solve the problems of large internal steel profile cross-sections, difficulty in tying stirrups in concrete beams, and the inability to simultaneously tie multiple stirrups inside and outside the steel profile. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a cavity-type connecting beam structure that can be internally connected with stirrups, thereby solving the problem that the existing internal steel section is large, the stirrups of the concrete beam are difficult to tie, and it is difficult to tie multiple stirrups inside and outside the steel at the same time.

[0004] The technical solution to achieve the above objective is: a hollow connecting beam structure that can accommodate internal stirrups, the connecting beam structure comprising:

[0005] The multiple horizontal plates are provided with multiple transverse partitions at intervals at both the upper and lower ends;

[0006] Multiple reinforcing bars are placed around the perimeter of multiple horizontal slabs;

[0007] The stirrups are set between two adjacent horizontal plates, the stirrups are staggered from the diaphragms, and the ends of the stirrups are connected and fixed to the corresponding reinforcing bars.

[0008] A concrete structure with embedded horizontal slabs, diaphragms, and stirrups.

[0009] The further improvement of this utility model is that: the horizontal plate is provided with multiple structural reinforcement bars on the side near the concrete structure.

[0010] A further improvement of this utility model is that a tie rod connects the structural reinforcement to the corresponding load-bearing reinforcement.

[0011] The further improvement of this utility model is that the two ends of the tie are hook-shaped.

[0012] The further improvement of this utility model is that the tie bars are spaced apart on the surfaces of the stressed bars and structural bars.

[0013] The technical solution of this utility model is further improved in that: one end of the stirrup passes through two adjacent horizontal plates and is connected to the upper reinforcing bar, and the other end of the stirrup is connected to the lower reinforcing bar.

[0014] A further improvement of this utility model is that the horizontal plates are arranged at intervals.

[0015] A further improvement of this utility model is that at least one stirrup is placed between two adjacent horizontal plates.

[0016] The further improvement of this utility model is that multiple studs are installed on the left and right sides of the horizontal plate.

[0017] A further improvement of this utility model is that the studs are spaced apart on the left and right sides of the horizontal plate.

[0018] By utilizing the above technical solution, the technical effects achieved by this utility model compared to the prior art are as follows:

[0019] This utility model provides a cavity-type connecting beam structure with internally inserted stirrups. By setting horizontal plates and transverse diaphragms inside the concrete structure, the cross-section between steel sections is reduced, and the internal cavity between the steel structure and the concrete structure is reduced. By adding horizontal plates, multiple sets of stirrups can be set simultaneously to tie the steel bars, reducing the difficulty of tying the stirrups to the steel bars and avoiding the problem of insufficient stirrup tying in steel-concrete beams.

[0020] By adding multiple horizontal plates, diaphragms, and main steel bars, the composite beam can leverage the mutual reinforcement and support characteristics of steel and reinforced concrete structures, thereby improving its stiffness, effectively resisting vertical loads from the building, reducing the compression of the composite beam under vertical loads, and exhibiting good load-bearing capacity, good ductility, and strong seismic resistance.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] This invention provides a cavity-type connecting beam structure with internally inserted stirrups. This device allows stirrups to pass through the internal space of horizontal diaphragms arranged at intervals on a horizontal plate, achieving the advantages of both steel and concrete structures. The cavity-type connecting beam structure with internally inserted stirrups is described below.

[0026] See Figure 1 This image shows a cross-sectional view of the node construction of a cavity-type connecting beam structure with internally inserted stirrups, according to the present invention. (See also...) Figure 2 This image shows a top view of the node construction of a cavity-type connecting beam structure with internally inserted stirrups, according to this utility model. The following is in conjunction with... Figures 1 to 2 The structure of the cavity-type connecting beam structure with internally inserted stirrups according to this utility model will be described.

[0027] See Figures 1 to 2 This utility model provides a cavity-type connecting beam structure with internally inserted stirrups. The connecting beam structure includes: reinforcing bars 1, transverse diaphragms 2, horizontal plates 5, stirrups 6, and concrete structure A. The horizontal plates 5 consist of multiple horizontal plates 5, with multiple transverse diaphragms 2 spaced apart at their upper and lower ends. Multiple reinforcing bars 1 are placed around the periphery of the horizontal plates 5. The stirrups 6 are positioned between adjacent horizontal plates 5, staggered from the transverse diaphragms 2, and their ends are connected and fixed to the corresponding reinforcing bars 1. The concrete structure A, which embeds the horizontal plates 5, transverse diaphragms 2, and stirrups 6, is also included.

[0028] Preferably, by installing the diaphragm 2 on the horizontal plate 5, the cross section within the concrete structure is reduced, allowing the stirrups 6 to pass through and be tied in the built-in space formed between the diaphragm 2 and the horizontal plate 5.

[0029] Furthermore, the diaphragms 2 are spaced apart on the horizontal plate 5, creating a sufficient internal cavity between them, allowing the stirrups 6 to pass through the internal cavity.

[0030] In one specific embodiment of this utility model, the horizontal plate 5 is provided with a plurality of structural reinforcement bars 3 on the side near the concrete structure A.

[0031] In one specific embodiment of this utility model, a tie bar 4 connects the structural reinforcement 3 to the corresponding load-bearing reinforcement 1.

[0032] Furthermore, the tie bar 4 is fixed by welding to the surface of the structural reinforcement bar 3 and the load-bearing reinforcement bar 1, and is embedded in the concrete structure A.

[0033] In one specific embodiment of this utility model, the two ends of the tie rod 4 are hook-shaped.

[0034] Furthermore, by setting both ends of the tie bar 4 into hook shapes, the two ends of the tie bar 4 can wrap around the structural reinforcement 3 and the load-bearing reinforcement 1, thereby more effectively fixing the structural reinforcement 3 and the load-bearing reinforcement 1.

[0035] In one specific embodiment of this utility model, the tie rods 4 are spaced apart on the surfaces of the load-bearing ribs 1 and the structural ribs 3.

[0036] In one specific embodiment of this utility model, one end of the stirrup 6 passes through two adjacent horizontal plates 5 and is connected to the upper reinforcing bar 1, and the other end of the stirrup 6 is connected to the lower reinforcing bar 1.

[0037] Preferably, the position of the stirrup 6 can be fixed by the reinforcing bars 1 at the upper and lower ends.

[0038] In one specific embodiment of this utility model, the horizontal plates 5 are arranged at intervals.

[0039] In one specific embodiment of this utility model, at least one stirrup 6 is placed between two adjacent horizontal plates 5.

[0040] Preferably, by arranging studs 7 on the horizontal plate 5, a good bond between the steel and the concrete structure can be achieved, increasing the contact area between the steel and the concrete and achieving a better connection effect.

[0041] In one specific embodiment of this utility model, multiple studs 7 are installed on the left and right sides of the horizontal plate 5.

[0042] Furthermore, by arranging the studs 7 at intervals in the horizontal plate 5, the stirrups 6 can be fixed without the studs 7 when passing through the built-in cavity.

[0043] In one specific embodiment of this utility model, the studs 7 are spaced apart on the left and right sides of the horizontal plate 5.

[0044] like Figures 1 to 2 As shown below, the installation process of a cavity-type connecting beam structure with internally inserted stirrups according to this utility model will be described.

[0045] First, studs 7 are spaced out on the horizontal plate 5. Then, a hollow steel section is formed by the transverse diaphragm 2 at the top and bottom of the horizontal plate 5. Next, stirrups 6 are passed through the hollow steel section, avoiding the studs 7. Then, the reinforcing bars 1 and structural bars 3 are placed around the perimeter of the hollow steel section. The structural bars 3 are tied with tie bars 4 to form a steel reinforcement system. Then, the stirrups 6 are fixed in position with the reinforcing bars 1. Finally, concrete is poured into the hollow steel section and the steel reinforcement system to form a connecting beam structure.

[0046] The beneficial effects of this utility model of a hollow connecting beam structure with internally inserted stirrups are as follows:

[0047] 1. By setting horizontal plates and diaphragms inside the concrete structure, the cross-section between steel sections is reduced, and the built-in cavity between the steel structure and the concrete structure is reduced. In addition, the horizontal plates enable the simultaneous setting of multiple sets of stirrups, reducing the difficulty of tying the stirrups to the steel bars.

[0048] 2. By adding multiple horizontal plates, diaphragms, and main steel bars, the composite beam can leverage the mutual reinforcement and support characteristics of steel and reinforced concrete structures, thereby improving its stiffness, effectively resisting vertical loads from the building, reducing the compression of the composite beam under vertical loads, and exhibiting good load-bearing capacity, good ductility, and strong seismic resistance.

[0049] 3. By binding the outer stirrups of the steel structure to the outside of the steel section, and binding the inner stirrups through the hollow steel section, the binding of the inner stirrups is convenient and the reinforcement ratio of the steel-concrete beam is improved. The vertical steel plate is equipped with studs, which can achieve a good combination between the steel section and the concrete structure, and give full play to the advantages of the steel structure and the reinforced concrete structure.

[0050] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
