Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of structural engineering, in particular to a beam reinforcing structure, a beam embedded part reinforcing device and a reinforcing method. BACKGROUND

[0002] The main plant building turbine room is an important part of the main plant building of a thermal power plant, and the exhaust pipe of the feed water pump turbine acts on the middle layer of the main plant building. The self weight of the exhaust pipe and the expansion force of the steam on the pipe act on the floor (the floor is pre-buried with a pre-buried part for fixing the exhaust pipe), which is a vertical downward pressure. When the feed water pump turbine works and exhausts, the exhaust pipe acting on the floor generates an upward pulling force on the pre-buried part, and the pulling force is of a large order of magnitude. If the upward pulling force is ignored at the initial stage of the construction of the plant building, the design strength of the original beam body will be seriously insufficient. In addition, when the unit equipment runs for a long time, the pre-buried part pre-buried in the floor is pulled out upward by the action of the repeated upward pulling force, which leads to the failure of the fixation of the exhaust pipe and causes a great safety hazard. Since the exhaust pipe is at a high temperature when the unit is running, and the reinforcement of the unit during shutdown will cause unpredictable losses to the power plant, how to realize the reinforcement of the above structure while minimizing the impact on the power plant has become a problem to be solved.

[0060] As shown in some embodiments of the present application, Figure 5 , Figure 6 The clamping piece 2 includes a horizontally arranged second hoop piece 22 and two first hoop pieces 21 arranged vertically, the two first hoop pieces 21 are correspondingly connected to the two side walls of the beam body, and the first hoop piece 21 and the side wall of the beam body are connected by the first anchor bolt 23, as shown in Figure 5 A plurality of first anchor bolts 23 are arranged vertically to anchor the first hoop piece 21 to the side wall of the beam body, the second hoop piece 22 is arranged below the bottom wall of the beam body, at least partially abuts against the bottom wall of the beam body, and the two ends of the second hoop piece 22 are correspondingly connected to the bottom ends of the two first hoop pieces 21 to form a clamping cavity in the combined area of the second hoop piece 22 and the two first hoop pieces 21, the outer wall of the first hoop piece 21 is fixedly connected with the through piece 1 at the position below the floor 8 by welding, and finally the clamping piece 2 composed of the two first hoop pieces 21 and the second hoop piece 22 is clamped and fixed on the outer peripheral wall of the beam body, thereby realizing the effect of reinforcing the beam body.

[0061] As shown in some embodiments of the present application, Figure 6As shown, the beam reinforcing structure further comprises a first connecting plate 101 extending along the length direction of the beam body, a second connecting plate 102 vertically connected to the bottom end of the first connecting plate 101, the first connecting plate 101 and the second connecting plate 102 constitute a connecting piece 10, two connecting pieces 10 are arranged at the connection position of the first hoop piece 21 and the second hoop piece 22, and the connecting piece 10 is used for connecting the two ends of the second hoop piece 22 with the first hoop piece 21 correspondingly; the first connecting plate 101 is clamped between the plurality of first hoop pieces 21 and the side wall of the beam body on the same side, one side of the first connecting plate 101 is attached to the beam body, and the other side is attached to the plurality of first hoop pieces 21 (the plurality of first hoop pieces 21 and the first connecting plate 101 are connected by welding); the second connecting plate 102 is clamped between the second hoop piece 22 and the bottom wall of the beam body, and two second connecting plates 102 are arranged at the two ends of the second hoop piece 22 along the length direction of the second hoop piece 22, one side of the second connecting plate 102 is attached to the second hoop piece 22 (the one end of the plurality of second hoop pieces 22 and the second connecting plate 102 are connected by welding), and the other side is attached to the bottom wall of the beam body; specifically, the bottom end of the side wall of the beam body (the corresponding region of the first connecting plate 101) is chiseled to make the first connecting plate 101 flush with the side wall of the beam body when the first connecting plate 101 is attached to the chiseled part; so as to realize the corresponding connection of the two ends of the second hoop piece 22 with the first hoop pieces 21 on both sides under the action of the two connecting pieces, and further make the clamping piece 2 composed of the first hoop piece 21, the second hoop piece 22 and the connecting piece 10 clamped and fixed on the outer peripheral wall of the beam body; it should be noted that: since the two second connecting plates 102 and the second hoop piece 22 have the effect of supporting the beam body, when the connecting piece 10 is arranged, the length of the second connecting plate 102 is greater than the length of the first connecting plate 101, and the contact area of the second connecting plate 102 and the second hoop piece 22 is increased as much as possible, so as to improve the reinforcing effect on the beam body.

[0062] In some embodiments of the present application, the first connecting plate 101 and the second connecting plate 102 are integrally formed or connected by welding, and when the first connecting plate 101 and the second connecting plate 102 are integrally formed, an angle steel (an unequal angle steel) can be selected, and the longer side of the angle steel is clamped between the second hoop piece 22 and the bottom wall of the beam body.

[0063] In some embodiments of the present application, as Figure 5As shown, the stopper 11 in the scheme is a nut screwed on the upper end of the through member 1 protruding out of the floor 8, and the through member 1 is a bolt rod with a threaded upper end for screwing the nut thereon; the nut in the scheme is provided with one or more, and the multiple nuts are in abutment in sequence, and the nut at the lowermost end is in abutment with the upper end face of the floor 8; thereby achieving the effect of limiting the through member 1 arranged in the opening, and through the limiting cooperation of the nut and the bolt rod, and the bolt rod is fixedly connected with the outer wall of the first hoop member 21 at the position below the floor 8, thereby achieving the effect of reinforcing the beam body, and the through member 1 (bolt rod) is welded to the first hoop member 21 in the scheme, and the two first hoop members 21 and the second hoop member 22 are connected through the connecting member 10, which plays the role of stirrup for the beam body. In order to further improve the reinforcing strength of the beam body, the nut and the through member 1 can be welded to improve the connection strength between the nut and the through member 1, and the limiting effect of the through member 1; at the same time, a certain thickness of concrete layer is poured above the beam body, which is used to cover and wrap the through member 1 protruding out of the floor 8 and the nut screwed on the upper end of the through member 1, so as to avoid the erosion of moisture in the external environment to the nut and the connecting part of the nut and the through member 1.

[0064] As shown in Figure 4 , Figure 13 As shown, the embodiment also provides a structure for reinforcing the connection between the beam and the column body 81. First, the protective layer of the side wall of the column body 81 is chiseled off for placing the auxiliary plate 811 (so that the auxiliary plate 811 and the protective layer of the column body 81 that is not chiseled off are flush), and the auxiliary plate 811 is anchored on the side wall of the column body 81 through the second anchor 813, and then the auxiliary angle steel 812 is welded below the two second connecting plates 102 (so that one side of the auxiliary angle steel 812 is connected with the two second connecting plates 102 and then welded), so that the other side of the auxiliary angle steel 812 is abutted and pressed on the auxiliary plate 811, and the second anchor 813 is arranged at the abutted and pressed position of the auxiliary angle steel 812 and the auxiliary plate 811, so as to connect the auxiliary angle steel 812 and the auxiliary plate 811. Through the above structure, the structural strength of the connection between the beam and the column body 81 is enhanced, thereby reinforcing the connection between the beam and the column body 81.

[0065] In the second aspect, the embodiment provides a beam embedded part reinforcing device for reinforcing the beam embedded part 9, and the beam is a concrete beam 6, and the embedded part 9 is a buried iron for fixing equipment (exhaust pipe), as shown in Figure 8As shown, the beam reinforcement structure in the above embodiment includes a through-piece 1 that passes upward through the floor slab 8 and the embedded part 9 in sequence, with a stop 11 abutting against the upper surface of the embedded part 9. Through the cooperation between the stop 11, the through-piece 1, the first hoop 21, the second hoop 22, and the connecting piece 10, the concrete beam 6 is reinforced while the embedded part 9, located on the concrete beam 6 and pre-embedded in the floor slab 8, is simultaneously reinforced. A washer can be provided between the nut at the lowest end and the upper surface of the embedded part 9 to improve the tightening effect. Figure 1 As shown, the embedded part 9 is pre-embedded in the floor slab 8 located above the beam and is set at intervals. In the parts where the embedded part 9 is not set, the beam is reinforced by the above-mentioned beam reinforcement structure. In the parts where the embedded part 9 is set, the beam reinforcement structure can not only reinforce the beam, but also reinforce the embedded part 9 pre-embedded in the floor slab 8 above the beam.

[0066] In some embodiments of this application, such as Figure 2 , Figure 8 As shown, the beam-embedded reinforcement device also includes auxiliary reinforcing members 3, which are I-beams. At least one auxiliary reinforcing member 3 is provided on each side of the concrete beam 6 along its width. The auxiliary reinforcing members 3 are arranged along the length of the concrete beam 6, and their upper surfaces are fitted against the bottom wall of the floor slab 8. Because the embedded part 9 is relatively wide, half of it acts on the floor slab 8. However, the thickness of the floor slab 8 is only 120mm (which is insufficient to meet the anchorage length of the anchor bar). Therefore, this solution provides at least one auxiliary reinforcing member 3 (I-beam) on each side of the concrete beam 6 within the projection area of ​​the embedded part 9 in the vertical direction to meet the anchorage requirements. A connecting member 4 (an anchor bar) is fixedly connected to the upper surface of the auxiliary reinforcing member 3 (welded to the upper surface of the auxiliary reinforcing member 3). The connecting member 4 passes upwards through the floor slab 8 and the embedded part 9 sequentially. Figure 10 , Figure 11 As shown, a welding hole (the inner diameter of the welding hole is slightly larger than the outer diameter of the connector 4) is provided through the embedded part 9 to cooperate with the connector 4. On the one hand, the connector 4 passes through the embedded part 9 upwards. On the other hand, when the connector 4 and the embedded part 9 are welded, the larger welding hole can accommodate more solder to improve the welding strength.

[0067] like Figure 9 As shown, the embedded part 9 located in the floor slab 8 above the concrete beam 6 is formed by splicing two embedded iron pieces together, thus forming a splice joint above the concrete beam 6. To improve the structural strength of the two embedded iron pieces at the splice joint, as shown... Figure 11As shown, a plurality of connecting reinforcing members 41 (as anchor bars) are arranged in the regions corresponding to the concrete beam 6 in the up-down direction on both sides of the joint between the two embedded iron pieces, and the connecting reinforcing members 41 in the regions correspond to the concrete beam 6, so that the thickness of the concrete beam 6 and the thickness of the floor 8 are sufficient to meet the anchoring requirements, and thus the anchoring at the above-mentioned positions can improve the joint strength between the two embedded iron pieces and improve the reinforcing effect on the two embedded iron pieces.

[0068] In some embodiments of the present application, as shown in Figure 1 As shown, the beam body below the unit equipment is the concrete beam 6 and the I-beam 7, and the embedded piece 9 is arranged on the concrete beam 6 and the I-beam 7, and the present embodiment provides a device for reinforcing the embedded piece 9 arranged in the floor 8 corresponding to the I-beam 7; as shown in Figure 3 As shown, the device comprises two lifting members 5 arranged on both sides of the I-beam 7 in the vertical width direction, and the lifting member 5 comprises a first pull rod 51 arranged vertically, a second pull rod 52 connected vertically to the bottom end of the first pull rod 51, the first pull rod 51 penetrates the floor 8 and the embedded piece 9 in sequence from top to bottom, and the upper end of the first pull rod 51 is fixedly connected (welded) to the embedded piece 9; the second pull rod 52 is arranged perpendicular to the length direction of the I-beam 7, and the outer periphery of the second pull rod 52 is fixedly connected to the lower end surface of the upper flange of the I-beam 7 (both are welded); the first pull rod 51 and the second pull rod 52 in the present scheme are integrally formed, and the material is steel bar (the steel bar is bent to obtain the above-mentioned lifting member 5); the first pull rod 51 is welded to the embedded piece 9, and the second pull rod 52 is welded to the lower end surface of the upper flange of the I-beam 7, so as to realize the reinforcing effect of the embedded piece 9 arranged in the floor 8 on the I-beam 7. In the present embodiment, a plurality of groups of two lifting members 5 are arranged in the length direction of the I-beam 7 and spaced apart from the corresponding regions of the embedded piece 9, so as to realize the reinforcing effect of the embedded piece 9 arranged in the floor 8 on the I-beam 7.

[0069] In a third aspect, the present embodiment provides a reinforcing method of the beam-embedded-piece reinforcing device, which comprises a concrete-beam-embedded-piece reinforcing method and an I-beam-embedded-piece reinforcing method.

[0070] The method for reinforcing the embedded part on the concrete beam comprises the following steps: clamping and fixing the clamping part 2 on the outer periphery of the concrete beam 6; opening a through hole which penetrates up and down at a position below the floor 8 and close to the side wall of the concrete beam 6, inserting the penetrating part 1 into the through hole, and fixing the upper end of the penetrating part 1 which extends out of the through hole to the outer wall of the clamping part 2; arranging the auxiliary reinforcing part 3 along the length direction of the concrete beam 6 on both sides of the concrete beam 6, welding the connecting part 4 to the upper end of the auxiliary reinforcing part 3 and making the connecting part 4 penetrate the floor 8 and the original embedded part 9 in sequence, and making the upper end surface of the auxiliary reinforcing part 3 abut against the bottom wall of the floor 8; welding the two ends of the auxiliary reinforcing part 3 along the length direction to the I-beam 7, so as to fix the auxiliary reinforcing part 3 to the bottom wall of the floor 8, thereby realizing the synchronous reinforcement of the concrete beam 6 below the floor 8 under the condition of the operation of the unit; when the equipment is stopped for maintenance, removing the original embedded part 9 on the concrete beam 6 and installing a new embedded part 9 (a hole is reserved in advance on the new embedded part 9 according to the position of the through hole on the floor 8, so as to be penetrated by the penetrating part 1); screwing one or more nuts to the upper end of the penetrating part 1 which extends out of the new embedded part 9, abutting the plurality of nuts and making the lowermost nut abut against the upper end surface of the new embedded part 9 (a gasket is arranged between the upper end surface of the new embedded part 9 and the lowermost nut), and welding the nut to the penetrating part 1, thereby realizing the reinforcement of the embedded part 9 in the floor 8 on the concrete beam 6 by using the downtime of the unit for maintenance.

[0071] The method for reinforcing the embedded part on the I-beam comprises the following steps: opening a through hole which penetrates up and down at a position below the floor 8 and close to the side of the I-beam 7; inserting the first pull rod 51 into the through hole, and welding the second pull rod 52 to the lower end surface of the upper flange of the I-beam 7; when the equipment is stopped for maintenance, removing the original embedded part 9 on the I-beam 7 and installing a new embedded part 9 (a hole is reserved in advance on the new embedded part 9 for the first pull rod 51 to penetrate), and welding the upper end of the first pull rod 51 to the new embedded part 9, thereby realizing the reinforcement of the embedded part 9 in the floor 8 on the I-beam 7 by using the downtime of the unit for maintenance.

[0072] In some embodiments of the present application, the contact parts between the new embedded part 9 and the floor 8 and between the clamping part 2 and the concrete beam 6 are filled with adhesive, as shown in Figs.
