Rotating the fixed screw rod can push the connecting support plate to move, and the connecting support plate drives the connecting sleeve to move.

[0024] Furthermore, the limiting nut can prevent the connecting support plate from falling off the fixing screw rod, thereby ensuring the safety of the movement of the connecting sleeve.

[0025] Furthermore, the limiting plate can prevent the supporting sliding rod from escaping from the limiting sliding sleeve, thereby further increasing the safety of the lateral reinforcement mechanism.

[0026] Furthermore, the connecting slide groove provides installation space for the driving machine and the connecting slide rod.

[0027] Furthermore, the connection motor rotates to drive the connection screw sleeve to rotate, and the connection screw moves along the length axis of the connection slide groove under the rotation of the connection screw sleeve, and the connection slide rod moves under the drive of the connection screw rod, thereby realizing the rising and falling action of the connection slide rod.

[0028] Furthermore, the top groove of the fixed slide plate can increase the friction between the fixed slide plate and the concrete bottom plate to resist the horizontal thrust caused by the side wall.

[0029] Furthermore, the support spring is used to connect the fixed slide plate and the connecting top plate, and can also assist the connecting top plate in resetting. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0037] The utility model discloses a reinforcement device for repairing a concrete structure of a house building, referring to Figure 1 , 2, including a hollow fixed rod 1, a connecting slide rod 11 and a driving machine are arranged inside the fixed rod 1, a driving end of the driving machine is connected to the connecting slide rod 11, and a connecting top plate 12 is arranged on the top of the connecting slide rod 11 by a bolt structure or welding. Figure 3 In this embodiment, the inner wall of the fixed rod 1 is provided with a connecting slot 3, and the driving machine is located inside the connecting slot 3; the driving machine includes a connecting motor 31 and a connecting screw 33, the inner side wall of the connecting slot 3 is installed with the connecting motor 31, the output end of the connecting motor 31 is fixedly connected with a connecting screw sleeve 32 through a coupling, the inner side wall of the connecting screw sleeve 32 is threadedly connected with the connecting screw 33, and the top of the connecting screw 33 is rotatably connected with the connecting slide bar 11. The connecting motor 31 rotates, driving the connecting screw sleeve 32 to rotate, and the connecting screw 33 is driven to rotate and lift by the rotation of the connecting screw sleeve 32, and the lifting of the connecting screw 33 pushes the connecting slide bar 11 to move upward, so that the connecting slide bar 11 slides out from the fixed rod 1, and the height of the whole device is adjusted. At the same time, the connecting slot 3 can play a role of limiting in the sliding process of the connecting slide bar 11, ensuring the stability and safety of the upward movement of the connecting slide bar 11. The driving machine can also be a driving unit that can realize reciprocating translation, such as a cylinder or a hydraulic cylinder.

[0038] The connecting slide bar 11 is also provided with a side reinforcement mechanism, see Figure 1 , 2 The side reinforcement mechanism includes a side driving member, a reinforcement connecting member and an anti-slip support plate 26. The reinforcement connecting member includes a limiting sleeve 24, a supporting slide bar 25 and a hinged rod 23. The length axis of the limiting sleeve 24 is perpendicular to the length axis of the connecting slide bar 11. One end of the limiting sleeve 24 is fixedly connected to the connecting slide bar 11, and the other end is suspended; one end of the supporting slide bar 25 is slidably connected to the limiting sleeve 24, and the other end is connected to the anti-slip support plate 26. The supporting slide bar 25 slides along the length axis of the limiting sleeve 24. One end of the hinged rod 23 is hinged to the bottom of the supporting slide bar 25, and the other end is hinged to the driving end of the side driving member. The two hinge axes of the hinged rod 23 are parallel, and the two hinge axes are perpendicular to the length axis of the connecting slide bar 11.

[0039] The side driving member includes a sleeve driving member and a connecting sleeve 2 as a driving end. The connecting sleeve 2 is sleeved on the connecting slide bar 11. The end of the hinged rod 23 away from the supporting slide bar 25 is hinged to the connecting sleeve 2. The sleeve driving member is fixed to the outer wall of the connecting slide bar 11, and the driving end of the sleeve driving member pushes the connecting sleeve 2 to slide along the length axis of the connecting slide bar 11. The connecting slide bar 11 guides the connecting sleeve 2 to slide. The hinged rod 23 can push the supporting slide bar 25 when the connecting sleeve 2 rises. When the connecting sleeve 2 rises, the angle of the hinged rod 23 will change, so that the hinged rod 23 pushes the supporting slide bar 25, so that the supporting slide bar 25 drives the anti-skid support plate 26 to connect with the side wall. In this embodiment, the hinged rod 23 and the sleeve driving member are on the side opposite to the connecting slide bar 11.

[0040] Reference Figure 1 , 2 5. The sleeve driving member includes a connecting support plate 28, a fixed support plate 21 and a fixed screw 22. The fixed support plate 21 is fixedly connected to the connecting slide rod 11. The fixed screw 22 penetrates the fixed support plate 21 and is connected to the connecting sleeve 2, and the fixed screw 22 is threadedly connected to the fixed support plate 21; the connecting support plate 28 is fixed to the outer side of the connecting sleeve 2 by a screw structure or welding, and the connecting support plate 28 is located above the fixed support plate 21. The fixed screw 22 sequentially penetrates the fixed support plate 21 and the connecting support plate 28, and the fixed screw 22 is threadedly connected to the connecting support plate 28.

[0041] A limit nut is provided at one end of the fixing screw rod 22 that passes through and extends out of the connecting support plate 28; a limit plate is provided at one end of the limit sleeve 24 that is away from the hinge rod 23. The limit nut and the limit plate are both used to ensure the safe sliding of the side reinforcement structure, which helps to improve the safety during construction.

[0042] Reference Figure 4 In order to resist the horizontal thrust caused by the side wall, a fixed slide plate 35 with a groove is provided on the connecting top plate 12. A plurality of support springs 34 are fixedly connected to the top of the connecting top plate 12, and a fixed slide plate 35 is fixedly connected to the top of the plurality of support springs 34, and the fixed slide plate 35 is slidably connected to the inner side wall of the connecting top plate 12. In this embodiment, the connecting top plate 12 is a box body with an opening upward, and a plurality of support springs 34 are provided at the bottom of the fixed slide plate 35, and the plurality of support springs 34 are arranged in a matrix, and one end of the support spring 34 away from the fixed slide plate 35 is fixed in the box body of the connecting top plate 12, and the telescopic axis of the support spring 34 is parallel to the rising axis of the connecting slide rod 11, and the support spring 34 is in an extended state when not working. In addition, a plurality of parallel grooves are provided on the fixed slide plate 35, and the length axis of the grooves is perpendicular to the length axis of the limiting sliding sleeve 24, and the grooves can increase the friction between the fixed slide plate 35 and the concrete bottom plate to resist the horizontal thrust caused by the side wall.

[0043] The anti-skid support plate 26 has the same structure as the fixed slide plate 35, that is, an anti-skid groove is provided on the anti-skid support plate 26, and the length axis of the anti-skid groove is perpendicular to the length axis of the connecting slide rod 11. The anti-skid groove can increase the friction between the anti-skid support plate 26 and the side wall to prevent the anti-skid support plate 26 from moving downward.

[0044] Reference Figure 5 In order to ensure that the connecting sleeve 2 slides smoothly on the connecting slide rod 11, a connecting roller 27 is provided on the inner side of the connecting sleeve 2. In this embodiment, the cross-sections of the connecting slide rod 11 and the connecting sleeve 2 are both rectangular, and can also be other non-circular cross-sections, so that axial rotation can be avoided during the sliding process, and the moving direction of the connecting slide rod 11 and the connecting sleeve 2 can be ensured.

[0045] The implementation principle of the reinforcement device for repairing the concrete structure of a house building of the utility model is as follows: when it is necessary to support the concrete bottom plate, first turn on the switch of the connecting motor 31, so that the connecting motor 31 drives the connecting screw sleeve 32 to rotate, and the rotation of the connecting screw sleeve 32 drives the internal connecting screw 33 to move upward, and the connecting screw 33 lifts the connecting slide bar 11 to lift the connecting slide bar 11 upward, and the lifting of the connecting slide bar 11 drives the connecting top plate 12 and the fixed slide plate 35 to be connected to the concrete top plate, and through the coordinated work between the supporting spring 34 and the fixed slide plate 35, the connection between the device and the concrete bottom plate can be made closer.

[0046] When the top support is completed, use a tool to rotate the fixing screw 22 to make the fixing screw 22 rotate in the fixing support plate 21. The rotation of the fixing screw 22 will drive the connecting sleeve 2 to slide and rise on the outside of the connecting slide rod 11. By connecting the connecting roller 27 and the connecting sleeve 2, the lubrication between the connecting slide rod 11 and the connecting sleeve 2 can be increased to avoid the connecting slide rod 11 and the connecting sleeve 2 from getting stuck when sliding. The rise of the connecting sleeve 2 will drive the hinge rod 23 to adjust the angle. When the hinge rod 23 adjusts the angle, it will exert force on the supporting slide rod 25, causing the supporting slide rod 25 to slide forward in the limiting sleeve 24, driving the anti-skid support plate 26 to be connected to the side wall concrete parts, thereby supporting the concrete of the side wall.

[0047] The utility model discloses a reinforcement device for repairing the concrete structure of a house building, which, when in use, supports the concrete wall surface at the side. With the setting of the jacking mechanism, the top and the side wall can be supported at the same time. There is no need to additionally set up a plurality of support rods to support different positions. In addition, since the connection between the device and the ceiling is relatively close, it is relatively stable when the support mechanism is used to support the side surface, and can effectively avoid falling off.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to impose any limitation on the technical solution of the present invention. Those skilled in the art should understand that, without departing from the spirit and principles of the present invention, the technical solution can also be subjected to several simple modifications and replacements, and these modifications and replacements are also within the scope of protection covered by the claims.
