Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgical production facilities, in particular to a novel corridor support beam. Background Art
[0002] Metallurgical workshops are mostly connected by corridors, so that materials can reach the designated location in both horizontal and vertical directions. The corridor section usually ends near the workshop, and the column foot of the corridor falls on a beam that is perpendicular to the direction of material transportation in the corridor, and the beam is supported on the brackets growing from the workshop columns.
[0003] In the related art, the common practice is to use the top of the cast-in-place reinforced concrete corbel beam to be flush connected to the column corbels on both sides, thereby forming the column foot support component of the corridor. The corbel beam is the cantilevered part of the workshop and is a cast-in-place reinforced concrete component, so it is very inconvenient to support the formwork on site. In particular, sometimes there are more than a dozen corridors connected to the industrial workshop. Following this solution will generate a large amount of additional construction measures costs, and the construction units generally have a poor response to this, which needs to be improved urgently. In addition, the traditional practice of flat connection between the concrete corridor beam and the top surface of the corbel is that the corridor beam can only be "suspended" by the bent steel bars of the corbel in terms of the force of the corbel, and the height of the cross-section of the corbel and the horizontal tensile steel bars of the corbel cannot be fully utilized, resulting in the design cross-section of the corbel being generally large, which is not ideal in terms of material consumption or appearance structure. Due to the large span of the corridor, the shear force transmitted from the corridor beam to the corbel is also large, which will require more bent steel bars of the corbel, and the horizontal tensile steel bars of the corbel and the vertical steel bars of the column are too dense at the anchorage in the column, causing construction difficulties, and the construction quality is also difficult to guarantee.
[0004] In view of this, it is necessary to propose a new type of corridor support beam to solve the above defects. Utility Model Content
[0005] The main purpose of the utility model is to provide a new type of corridor support beam, aiming to solve the problem that the existing concrete corridor beam and the column corbel adopt the method of flat connection to meet the bearing capacity, but more corbel bent steel bars need to be configured, which leads to too dense bent steel bars, thus causing construction difficulties and the inability to ensure quality.
[0006] To achieve the above-mentioned purpose, the utility model provides a new type of corridor support beam, including a column, a cross beam and a pressure plate, wherein a corbel is cantilevered from the column, and both ends of the cross beam are respectively supported on the corbels extending outward from two adjacent columns, one end of the pressure plate is fixed to the column, and the other end is a free end and extends along the extending direction of the corbel, and the other end of the pressure plate is crimped onto the cross beam.
[0007] Preferably, the cross beam comprises a bottom plate, an intermediate support plate and a top plate, the bottom plate and the top plate are arranged in parallel and spaced apart, and the intermediate support plate is fixedly connected between the bottom plate and the top plate.
[0008] Preferably, the crossbeam is an I-beam.
[0009] Preferably, embedded parts are embedded in the corbel, and the crossbeam is connected and fixed to the embedded parts.
[0010] Preferably, the cross beam and the corbel are connected via fasteners.
[0011] Preferably, the fastener is a bolt.
[0012] Preferably, the pressing plate is a steel plate or a channel steel.
[0013] Preferably, it also includes a plurality of transverse stiffening ribs arranged at intervals, each of the transverse stiffening ribs is inserted into the space enclosed by the top plate, the middle support plate and the bottom plate, and the three side surfaces are respectively connected to the top plate, the middle support plate and the bottom plate.
[0014] Preferably, the transverse stiffening ribs are welded to the cross beams.
[0015] Compared with the prior art, the novel corridor support beam provided by the utility model has the following beneficial effects:
[0016] The new corridor supporting beam provided by the utility model directly overlaps the cross beam on the corbels extending outward from the columns, so that the cross beam can be installed by a hoisting scheme without the need to be integrally formed with the corbels on the columns. This changes the traditional method of using cast-in-place reinforced concrete corbel beams with the top flush with the two sides of the corbels. The installation and production are simpler, the stress on the corbels is changed, the number of bent steel bars used is greatly reduced, and the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Please refer to Figure 1 and Figure 2The utility model provides a new type of corridor support beam. The new type of corridor support beam includes a column 10, a crossbeam 1 and a pressure plate 2. A corbel 20 is cantilevered on the column 10. The crossbeam 1 is supported on the corbels 20 extending outward from two adjacent columns 10. The pressure plate 2 is a cantilever structure, one end of which is fixed on the column 10, and the other end is a free end and extends along the extending direction of the corbel 20. The other end of the pressure plate 2 is crimped on the top of the crossbeam 1. The crossbeam 1 is supported on the corbels 20 extending outward from the column 10, so that the crossbeam 1 can be installed by a hoisting scheme without the need to be integrally formed with the corbels 20 on the column 10, which changes the traditional method of using cast-in-place reinforced concrete corbels 20 with the top of the beam flush with the two sides of the corbels 20. The installation method of the crossbar changes the stress condition of the corbels 20 and reduces the stress on the bent steel bars on the corbels, so that the number of bent steel bars 30 used can be reduced. It should be explained that in the prior art, the crossbeam 1 is made of concrete, and the existing crossbeam and the corbel 20 are cast as one body, and are connected flush between the two corbels 20. The two corbels 20 bear vertical forces and inclined tensile forces, which results in a large number of steel bars inside the corbels 20 to meet the load requirements. In the solution of the utility model, the corbel 20 is subjected to vertical forces, and there is no need to use more steel bars to support the forces in all directions, thus greatly reducing the amount of materials used and reducing costs.
[0028] like Figure 3 As shown, the stress condition of the bent steel bars in the prior art conforms to the formula: sinα×As=F1, As is the stress value of the bent steel bars, F1 is the vertical force transmitted to the corbel from the corbel beam, and the stress on the horizontal bent steel bars is large.
[0029] like Figure 4 As shown, Figure 4 This is the force analysis diagram of the corbel. The force of the corbel is calculated by the formula calculate.
[0030] In the above formula, Fv is the vertical force acting on the top of the corbel, h0 is the height of the corbel, a is the horizontal distance from the Fv vertical force point to the edge of the column, fy is the tensile strength of the horizontal tensile reinforcement, and As is the area of the horizontal tensile reinforcement required to withstand the vertical force. The gravity of the beam is transmitted to the column through the corbel, and the bearing capacity is stronger.
[0031] The cross beam 1 includes a top plate 11, an intermediate support plate 13 and a bottom plate 15. The bottom plate 15 and the top plate 11 are arranged in parallel and spaced apart, and the intermediate support plate 13 is fixedly connected between the bottom plate 15 and the top plate 11. The bottom plate 15, the intermediate support plate 13 and the top plate 11 are made of steel, and the three are fixed by welding. It can be understood that the cross beam 1 made of steel can be recycled later, which reduces the cost.
[0032] Specifically, in this embodiment, the cross beam 1 is an I-beam, that is, the cross section of the cross beam 1 is in the shape of an I-shaped beam. Of course, in other embodiments, the cross beam 1 may also be other special-shaped structures.
[0033] In this embodiment, an embedded part is pre-embedded on the top surface of the corbel 20, and the cross beam 1 is connected and fixed to the embedded part. Specifically, the embedded part is an embedded steel plate, and the bottom plate 15 of the cross beam 1 is fixed to the embedded part by welding.
[0034] Of course, the cross beam 1 and the corbel 20 can also be connected by a fastener. Specifically, the fastener is a bolt. The bolt passes through the bottom plate 15 to fix the cross beam 1 on the corbel 20. This form can also fix the cross beam 1.
[0035] The pressing plate 2 is in the form of a cantilever beam, that is, one end is fixed on the column 10 and the other end is suspended. The pressing plate 2 is a steel plate or a channel steel, and the bottom surface in contact with the cross beam is a plane. Specifically, in this embodiment, the pressing plate 2 is a channel steel with a U-shaped cross section, and the pressing plate 2 presses the cross beam 1 on the corbel 20 to limit the upward freedom of the cross beam 1.
[0036] In another preferred embodiment, the novel corridor support beam further includes a plurality of transverse stiffening ribs 3 arranged at intervals, and the plurality of transverse stiffening ribs are arranged at intervals along the length direction of the crossbeam 1. Each of the transverse stiffening ribs is inserted into the space enclosed by the top plate 11, the middle support plate 13 and the bottom plate 15, and the three sides are connected to the top plate 11, the middle support plate 13 and the bottom plate 15 respectively.
[0037] Specifically, the transverse stiffening rib 3 is vertically welded to the crossbeam 1. The transverse stiffening rib 3 is a square steel plate with a certain thickness. The three sides of the steel plate are respectively welded to the top plate 11, the middle support plate 13 and the bottom plate 15 to strengthen the connection strength between the top plate 11, the middle support plate 13 and the bottom plate 15, thereby strengthening the overall strength of the crossbeam 1.
[0038] The novel corridor supporting beam provided by the utility model directly overlaps the cross beam 1 on the corbel 20 extending outward from the column 10, so that the cross beam 1 can be installed by a hoisting scheme without being integrally formed with the corbel 20 on the column 10, which changes the traditional method of using cast-in-place reinforced concrete corbel 20 and connecting the top of the beam flush with the two sides of the corbel 20, makes installation and production simpler, changes the force on the corbel 20, reduces the force on the bent steel bars, greatly reduces the number of bent steel bars used, and reduces costs.
[0039] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
