Description

TECHNICAL FIELD

[0001] The application relates to the technical field of house beam reinforcement, in particular to an old house beam reinforcement system and a reinforcement method. BACKGROUND

[0002] At present, after long-time use, old houses are prone to structural aging and insufficient bearing capacity, and thus the house structure needs to be reinforced.

[0003] The method of sticking steel plates to the bottom of the beam is commonly used to reinforce the house beam, so as to strengthen the bending resistance of the house beam. In the process of the steel plate reinforcement process, the glue on the steel plate needs to be thick in the middle and thin on both sides, so that when the steel plate is pasted to the house beam, the glue can overflow from the middle to both sides to reduce the occurrence of hollowing. However, it is difficult for beginners to control the thickness of the glue on the steel plate. SUMMARY

[0004] In order to facilitate the control of the thickness of the glue on the steel plate, the application provides an old house beam reinforcement system and a reinforcement method.

[0005] In the first aspect, the application provides an old house beam reinforcement system, which adopts the following technical scheme:

[0006] An old house beam reinforcement system comprises a reinforcing steel plate and a bracket assembly. The reinforcing steel plate comprises an outer frame and an inner plate. The inner plate slides in the outer frame along the vertical direction of the outer frame plate surface. The inner plate can be moved to a first state and a second state on the outer frame. When the inner plate is in the first state relative to the outer frame, the upper surface of the inner plate is lower than the upper surface of the outer frame to form a sink for filling glue. When the inner plate is in the second state relative to the outer frame, the upper surface of the inner plate is flush with the upper surface of the outer frame. The bracket assembly is used to stick the reinforcing steel plate to the bottom of the house beam and move the inner plate on the outer frame from the first state to the second state, so that the inner plate extrudes the glue out of the sink.

[0007] By adopting the above technical scheme, the sink for filling glue is formed by the relative movement between the outer frame and the inner plate. When the reinforcing steel plate is in the second state, the thickness of the glue in the middle of the reinforcing steel plate is greater than that of the glue on the side of the reinforcing steel plate. When the reinforcing steel plate extrudes the glue upward, the glue in the middle can expand and overflow to both sides, thereby improving the convenience of controlling the thickness of the glue on the reinforcing steel plate.

[0008] Optionally, the bracket assembly comprises a support frame, a counterweight seat moving up and down on the support frame, and a connecting rope penetrating through the outer frame and the inner plate, the opposite ends of the connecting rope extending out of the opposite sides of the outer frame and being connected with the counterweight seat, and when the connecting rope is straightened in the reinforced steel plate, the inner plate is in the second state relative to the outer frame.

[0009] The support frame has a first reversing part for hanging the connecting rope, the first reversing part being located between the outer frame and the counterweight seat, and the first reversing part being opposite to the roof beam.

[0010] By adopting the above technical scheme, the connecting rope is hung on the first reversing part after moving out of the outer frame and is connected with the counterweight seat, so that the counterweight seat can drive the connecting rope to be straightened in the reinforced steel plate when the counterweight seat moves downward, the inner plate can extrude the rubber material into the sink, and the reinforced steel plate can be pressed upward to the bottom of the roof beam.

[0011] Optionally, the opposite sides of the outer frame move with a stop rail, the outer frame has a spring member driving the stop rail to protrude out of the surface of the outer frame, the outer frame has a receiving groove for accommodating the stop rail, and a linkage rope is connected between the stop rail and the connecting rope, so that when the connecting rope moves the inner plate to the second state, the linkage rope drives the stop rail to be accommodated in the receiving groove.

[0012] By adopting the above technical scheme, the stop rail can limit the rubber material on the outer frame, so that the rubber material is not easy to overflow from the sides of the reinforced steel plate before the stop rail is accommodated.

[0013] Optionally, the receiving groove penetrates through the side of the outer frame, the outer frame has a second reversing part on the outer side wall for the connecting rope to pass through, the second reversing part is located between the first reversing part and the outer frame, and the connecting rope moves in the direction of entering the second reversing part to drive the linkage rope to pull the stop rail close to the receiving groove.

[0014] By adopting the above technical scheme, the cooperation of the connecting rope and the second reversing part enables the connecting rope to be straightened to drive the rubber material to move out of the sink, and simultaneously drives the stop rail to be accommodated in the receiving groove, so that the excess rubber material between the roof beam and the reinforced steel plate can overflow from the sides of the reinforced steel plate.

[0015] Optionally, the outer frame has a limiting column protruding out of the surface of the outer frame, the limiting column has a spring layer at the end far away from the outer frame, and when the stop rail protrudes out of the outer frame to the maximum distance, the side of the stop rail far away from the outer frame is higher than the end of the limiting column far away from the outer frame.

[0016] By adopting the technical scheme, the limiting column can prevent the reinforcing steel plate from being pressed against the house beam endlessly, so as to ensure the thickness of the adhesive layer between the reinforcing steel plate and the house beam, and the elastic layer can be deformed to a certain extent to enable the adhesive to be pressed by the reinforcing steel plate.

[0017] Optionally, the reinforcing system further comprises a reinforcing bar, a reinforcing rib and a side plate, the reinforcing bar is transversely inserted into the house beam, the reinforcing bar is provided with a through hole for the connecting rope to pass through, the reinforcing rib is used for being inserted into the outer frame and the inner plate simultaneously after the outer frame is flush with the inner plate, the reinforcing rib extends out from the reinforcing steel plate corresponding to the reinforcing bar, and the side plate is sleeved on the corresponding reinforcing bar and reinforcing rib and adhered to the side of the house beam.

[0018] By adopting the technical scheme, the stability between the outer frame and the inner plate is improved by inserting the reinforcing rib, the bending resistance of the house beam is improved by the reinforcing bar, and the reinforcing steel plate is further limited by the cooperation of the side plate, the reinforcing rib and the reinforcing bar.

[0020] By adopting the technical scheme, the power source drives the rotating rods on the two supports to rotate synchronously, that is, the support seat can be driven to move upward and downward relative to the support, so as to drive the counterweight seat to move upward and downward.

[0021] Optionally, the support comprises a support rod, a sliding sleeve and an abutting seat, the sliding sleeve is slidably sleeved on the support rod to adjust the extension length of the support, and the abutting seat is threadedly connected to the outer wall of the support rod and located at the bottom of the sliding sleeve.

[0022] By adopting the technical scheme, the sliding sleeve is moved, so that the two ends of the support abut between the ceiling and the ground respectively, thereby improving the stability of the support.

[0023] Optionally, the lower surface of the inner plate is provided with an extension part, when the inner plate is in the first state relative to the outer frame, a limiting cavity is formed between the extension part and the lower surface of the outer frame, the counterweight seat is provided with a limiting part for being inserted into the limiting cavity to limit the relative movement of the outer frame and the inner plate, and the counterweight seat is provided with a driving piece for driving the limiting part to move.

[0024] By adopting the technical scheme, the relative movement between the inner plate and the outer frame in the first state is limited by the cooperation of the limiting part and the limiting cavity, so that the reinforcing steel plate can be driven by the counterweight seat to move upward and close to the house beam in the second state, thereby improving the stability of the sink when the reinforcing steel plate moves upward.

DETAILED DESCRIPTION

[0044] The following will be described in detail in combination with the accompanying Figures 1-10 The present application will be further described in detail.

[0045] The embodiment of the present application discloses a house beam reinforcing system for old houses. Referring to Figure 1 , the house beam reinforcing system for old houses comprises a reinforcing steel plate 2 and a bracket assembly, the reinforcing steel plate 2 is pasted to the bottom of the house beam 1 through a glue, and the glue is an epoxy resin glue in the embodiment; the bracket assembly supports and draws the reinforcing steel plate 2 to drive the reinforcing steel plate 2 to move to the bottom of the house beam 1.

[0046] Referring to Figure 2 and Figure 3The reinforcing steel plate 2 comprises an outer frame 201 and inner plates 202. The outer frame 201 is in the shape of a square frame, and the length of the outer frame 201 is consistent with the length of the house beam 1, and the width of the outer frame 201 is consistent with the width of the house beam 1. The inner plates 202 are in the shape of square plates, and the middle part of the outer frame 201 forms a movable cavity for the inner plates 202 to slide up and down along the direction perpendicular to the plate surface of the outer frame 201, and the movable cavity penetrates through the upper and lower surfaces of the outer frame 201. The plate surface of the inner plate 202 is parallel to the plate surface of the outer frame 201, and the thickness of the inner plate 202 is consistent with the thickness of the outer frame 201. The two ends of the inner plate 202 that are far away from each other have a stroke block 24, and the outer frame 201 is provided with a stroke groove 25 corresponding to the stroke block 24 for the stroke block 24 to slide up and down, and the stroke groove 25 penetrates through the upper surface of the outer frame 201.

[0047] With reference to Figure 3 And Figure 4 When the inner plate 202 moves to the position where the stroke block 24 abuts against the inner bottom surface of the stroke groove 25, the inner plate 202 is in the first state relative to the outer frame 201, and at this time, the inner plate 202 sinks relative to the outer frame 201, and the upper surface of the inner plate 202 is lower than the upper surface of the outer frame 201, so that a sunken groove 3 is formed between the upper surface of the inner plate 202 and the inner wall of the movable cavity. When the reinforcing steel plate 2 is coated with glue, the glue is accumulated on the upper surfaces of the outer frame 201 and the inner plate 202, so that part of the glue enters the sunken groove 3, thereby making the thickness of the glue in the middle part of the reinforcing steel plate 2 more than the thickness of the glue in the surrounding part.

[0048] With reference to Figure 4 And Figure 5 When the inner plate 202 moves to the position where the upper surface of the stroke block 24 is flush with the upper surface of the outer frame 201, the inner plate 202 is in the second state relative to the outer frame 201, and at this time, the upper and lower surfaces of the inner plate 202 are respectively flush with the upper and lower surfaces of the outer frame 201.

[0049] With reference to Figure 1 And Figure 4 When the bracket assembly moves the reinforcing steel plate 2 to the position close to the bottom of the house beam 1, the bracket assembly drives the inner plate 202 to move from the first state to the second state, so that the inner plate 202 extrudes the glue out of the sunken groove 3. In the process that the reinforcing steel plate 2 is extruded upward to the bottom of the house beam 1, the glue in the middle part of the reinforcing steel plate 2 overflows to the side part, so as to fill the space between the reinforcing steel plate 2 and the house beam 1.

[0050] With reference to Figure 4 And Figure 6, the bracket assembly comprises a support frame 4, a counterweight seat 5 and a connecting rope 6. The outer frame 201 is provided with a first through hole 26 for the connecting rope 6 to pass through along the width direction of the outer frame 201, and the inner plate 202 is provided with a second through hole 27 for the connecting rope 6 to pass through along the width direction of the inner plate 202, and the end of the first through hole 26 towards the inner plate 202 is flared to enable the connecting rope 6 to be bent. The connecting rope 6 is simultaneously threaded through the first through hole 26 and the second through hole 27 on the outer frame 201 and the inner plate 202, and the two ends of the connecting rope 6 away from each other are respectively threaded out from the opposite sides of the outer frame 201.

[0051] When the inner plate 202 is in the first state relative to the outer frame 201, the connecting rope 6 is bent at the first through hole 26 and then enters the second through hole 27, and when the two ends of the connecting rope 6 are pulled in the direction away from each other to straighten the connecting rope 6 in the outer frame 201, the connecting rope 6 drives the inner plate 202 to move upwards relative to the outer frame 201 to the second state.

[0052] Referring to Figure 6 and Figure 7 , the positions and the number of the support frames 4 correspond to the connecting rope 6 one by one, and the support frames 4 are erected between the ground and the ceiling, and the top of the support frame 4 is provided with a first reversing part 7, and the first reversing part 7 comprises a base fixed with the support frame 4 and a pulley rotatably connected to the base, and the pulley has a sliding groove. Figure 4 The counterweight seat 5 moves up and down on the support frame 4, and the upper surface of the counterweight seat 5 is fixed with two hanging rings 28 for the two ends of the connecting rope 6 away from each other to be hung.

[0053] Referring to Figure 7 and Figure 8 , each support frame 4 has two first reversing parts 7, and the two first reversing parts 7 are respectively opposite to the two sides of the roof beam 1, and the two first reversing parts 7 correspond to the two ends of the connecting rope 6 away from each other one by one. Figure 4 After the ends of the connecting rope 6 extend out of the outer frame 201, they extend upwards to the pulley of the first reversing part 7, and then extend downwards to the hanging ring 28 of the counterweight seat 5 through the sliding groove and are hung on the pulley, and then are hooked or tied to the hanging ring 28, so that when the counterweight seat 5 moves downwards, the reinforced steel plate 2 moves upwards.

[0054] Referring to Figure 6, specifically, in order to drive the counterweight seat 5 to move, each support frame 4 comprises two supports 41 and two rotating rods 42, the supports 41 correspond to the rotating rods 42 one by one, the two first reversing parts 7 in the support frame 4 are installed on the two supports 41 respectively, the rotating rod 42 is rotationally connected to the corresponding support 41, and the length direction of the rotating rod 42 extends along the vertical direction. The support 41 is provided with a power source 18 for driving the rotating rod 42 to rotate, and the power source 18 is a rotating motor installed on the support 41, and the output end of the rotating motor is coaxially fixed with the rotating rod 42. The counterweight seat 5 is plate-shaped, and the two ends of the counterweight seat 5 are detachably connected with the first mounting seat 29 through the flange and bolt cooperation (not shown in the figure), and the first mounting seat 29 at the two ends of the counterweight seat 5 is slidably sleeved on the two rotating rods 42 in the support frame 4 respectively. And the outer wall of the two rotating rods 42 on the support frame 4 is threadedly connected with the second mounting seat 30, the second mounting seat 30 is located below the first mounting seat 29, and the two second mounting seats 30 are detachably connected with the support seat 19 through the flange and bolt cooperation (not shown in the figure). The support seat 19 is plate-shaped, and the upper surface of the support seat 19 abuts against the lower surface of the counterweight seat 5 to support the counterweight seat 5.

[0055] When the two rotating rods 42 on the support frame 4 rotate synchronously under the drive of the rotating motor, the second mounting seat 30 drives the support seat 19 to move up and down relative to the rotating rod 42 under the limiting action of the support seat 19. The support seat 19 moves upward to support the counterweight seat 5 to move upward, and the support seat 19 moves downward, and the counterweight seat 5 moves downward under the action of its own gravity.

[0056] Referring to Figure 4 , further, in order to prevent the inner plate 202 from extruding the glue out of the sink 3 too early during the lifting to the bottom of the house beam 1, the lower surface of the inner plate 202 is fixed with an extension 20 on the opposite sides along the width direction of the inner plate 202. The extension 20 is plate-shaped structure with the plate surface parallel to the plate surface of the inner plate 202, so that when the inner plate 202 is in the first state relative to the outer frame 201, the upper surface of the extension 20 and the lower surface of the outer frame 201 form a limiting cavity 21 with an opening towards the side of the outer frame 201.

[0057] Referring to Figure 7 , the upper surface of the counterweight seat 5 moves away from the two ends of the limiting cavity 21, and the limiting part 22 corresponding to the limiting cavity 21 is arranged on the two ends of the counterweight seat 5. The limiting part 22 is plate-shaped structure with the thickness consistent with the thickness of the limiting cavity 21, and the counterweight seat 5 is provided with a driving part 23 for driving the limiting part 22 to move along the width direction of the house beam 1. The driving part 23 is an electric telescopic rod installed on the upper surface of the counterweight seat 5, and the telescopic rod head of the electric telescopic rod is connected with the limiting part 22. The limiting parts 22 at the two ends of the counterweight seat 5 are opposite to each other.

[0058] Referring to Figure 4 and Figure 7Before the adhesive is applied, the support frame 4 is assembled, the reinforcing steel plate 2 is placed on the counterweight seat 5 of the support frame 4, the counterweight seats 5 of all the support frames 4 are at the same height, the reinforcing steel plate 2 is adjusted to the first state, the telescopic rod of the electric telescopic rod is extended, the limiting portions 22 at the two ends of the counterweight seat 5 are respectively inserted into the limiting cavities 21 on the opposite sides of the reinforcing steel plate 2, the limiting portions 22 at the two ends of the counterweight seat 5 jointly clamp and support the reinforcing steel plate 2, and the limiting portions 22 limit the relative displacement between the inner plate 202 and the outer frame 201.

[0059] Therefore, when the support seat 19 drives the counterweight seat 5 to move upward, the counterweight seat 5 drives the reinforcing steel plate 2 to move upward while keeping the first state; when the reinforcing steel plate 2 moves close to the bottom of the house beam 1, the telescopic rod of the electric telescopic rod is retracted to drive the limiting portions 22 to disengage from the limiting cavities 21, the two ends of the connecting rope 6 that are away from each other are connected to the hanging ring 28 on the counterweight seat 5 through the two first reversing portions 7 respectively, then the support seat 19 drives the counterweight seat 5 to move downward, and the counterweight seat 5 moves downward by its own gravity, gradually pulls the connecting rope 6 to make the connecting rope 6 straight in the reinforcing steel plate 2, and presses the reinforcing steel plate 2 to the bottom of the house beam 1.

[0060] With reference to Figure 7 In addition, in order to improve the stability of the support 41, the support 41 comprises a support rod 411, a sliding sleeve 412 and an abutting seat 413. The support rod 411 is in the shape of a screw rod extending in the vertical direction, and a base is fixed to the bottom of the support rod 411. The rotating rod 42 and the rotating motor are installed on the base. The sliding sleeve 412 is slidably sleeved on the top of the support rod 411, and a top seat is fixed to the top of the sliding sleeve 412. The top seat is in the shape of a plate, and a connecting rod 31 extending in the direction perpendicular to the axis of the support rod 411 is fixed to the top of the support rod 411. One end of the connecting rod 31 away from the support rod 411 is rotatably sleeved on the outer wall of the top end of the rotating rod 42. A clearance groove is formed in the sliding sleeve 412 to allow the sliding sleeve 412 to move up and down, and the sliding sleeve 412 is limited from rotating relative to the support rod 411 by the cooperation of the clearance groove and the connecting rod 31. The abutting seat 413 is threadedly connected to the outer wall of the support rod 411 and located at the bottom of the sliding sleeve 412.

[0061] When the support 41 is installed, the sliding sleeve 412 is moved upward to abut against the ceiling, and then the abutting seat 413 is threadedly moved to abut against the bottom of the sliding sleeve 412, so that the support 41 is limited between the ground and the ceiling and supports the ceiling.

[0062] With reference to Figure 2 and Figure 4The outer frame 201 can have a baffle 8 moving thereon, which is in the shape of a long strip in the length direction of the outer frame 201. The baffle 8 has a plurality of groups in the length direction of the outer frame 201, each group of baffles 8 corresponds to a connecting rope 6, and each group of baffles 8 has two baffles 8 moving away from each other along the direction perpendicular to the plate surface of the outer frame 201. The two sides of the outer frame 201 away from each other are provided with a receiving groove 10 for the baffles 8 to slide up and down, the receiving groove 10 penetrates the side of the outer frame 201, and the opposite ends of the two baffles 8 adjacent in the length direction of the outer frame 201 are close to each other.

[0063] The outer side wall of the baffle 8 is fixed with a linkage rope 11 connected with the connecting rope 6, and the outer frame 201 has a elastic member 9 for driving the baffle 8 to move upward to protrude above the upper surface of the outer frame 201. When the inner plate 202 is in the first state, the baffle 8 protrudes above the outer frame 201 under the elastic force of the elastic member 9 to enclose a space for the rubber material to accumulate, so that the rubber material is not easy to overflow under the blocking of the baffle 8. In combination Figure 5 When the inner plate 202 moves upward to the second state, the baffle 8 is pulled downward by the cooperation of the connecting rope 6 and the linkage rope 11, and the baffle 8 is pulled to be completely accommodated in the receiving groove 10, so that when the inner plate 202 extrudes the rubber material upward, there is a space between the outer frame 201 and the roof beam 1 for the excess rubber material to overflow.

[0064] Referring to Figure 9 Specifically, the elastic member 9 includes a moving block 91 and a spring 92. The moving block 91 is fixed to one side of the baffle 8 close to the inner plate 202. The inner wall of the side of the receiving groove 10 close to the inner plate 202 is provided with a moving groove 32 for the moving block 91 to slide up and down. The moving groove 32 does not penetrate the upper and lower sides of the outer frame 201, and the moving block 91 is in the shape of a swallowtail to limit the moving block 91 from moving outward out of the moving groove 32. During assembly, the moving groove 32 is first communicated with the upper part of the outer frame 201, then the moving block 91 is assembled into the moving groove 32, and finally the top of the moving groove 32 is supplemented. The spring 92 is connected to the lower surface of the moving block 91 and the inner bottom wall of the moving groove 32. The elastic force of the spring 92 is used to drive the moving block 91 to move upward to the top wall of the moving groove 32, so that the baffle 8 protrudes upward above the upper surface of the outer frame 201.

[0065] Referring to Figure 8 and Figure 9, the second reversing part 12 is located at the bottom side of the outer frame 201. When the end of the connecting rope 6 extends out of the side of the outer frame 201, it first passes downward around the pulley and is hung in cooperation with the pulley, and then extends upward and cooperates with the first reversing part 7, and the connecting point of the connecting rope 6 and the linkage rope 11 is located between the second reversing part 12 and the outer frame 201. When the counterweight base 5 drives the connecting rope 6 to be straightened in the reinforced steel plate 2, the connecting rope 6 drives the connecting point of the linkage rope 11 and the blocking edge 8 downward to pull the blocking edge 8 to be completely accommodated in the containing groove 10.

[0066] With reference to Figure 2 and Figure 10 Further, a limiting column 13 is arranged between two adjacent blocking edges 8 along the length direction of the support base 19, the limiting column 13 extends along the direction perpendicular to the plate surface of the outer frame 201, the limiting column 13 is fixed to the upper surface of the outer frame 201, and the end of the limiting column 13 away from the outer frame 201 is provided with an elastic layer, which is made of rubber with certain elasticity in the embodiment. When the moving block 91 abuts against the top wall in the moving groove 32 to make the distance of the blocking edge 8 protruding out of the upper surface of the outer frame 201 maximum, the upper surface of the blocking edge 8 is higher than the upper surface of the limiting column 13.
