Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a steel bar connection grouting sleeve bracket. Background Art

[0002] In prefabricated concrete structures, the vertical steel bar connections of prefabricated walls and the horizontal steel bar connections of prefabricated beams are often connected by grouting sleeves. According to the current relevant national standards, before the production of prefabricated components and the grouting construction on the construction site, the grouting sleeve steel bar connection joint test pieces must be made in accordance with relevant regulations. After being sent to the testing unit for tensile strength testing and passing the test, the component production and on-site grouting construction can be carried out. The grouting sleeve steel bar connection joint test piece testing is a necessary step to prove the quality of the grouting joint.

[0003] At present, when making grouting sleeve connection joint specimens, the steel bars at both ends of the grouting sleeve joint are usually directly fixed, so that the upper and lower steel bars of the grouting sleeve and the center of the grouting sleeve cannot be adjusted, thereby reducing the applicability of the device. When the position needs to be adjusted, the staff is required to remove the grouting sleeve and the connected steel bars and reinstall them, which is not only time-consuming and labor-intensive, but also increases the burden on the staff.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0005] The utility model aims to provide a steel bar connection grouting sleeve bracket, which can solve the problem that the grouting sleeve is inconvenient to adjust the position in the prior art.

[0006] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0007] A steel bar connection grouting sleeve bracket, comprising: a pair of support bases, a lifting drive assembly and a lifting support assembly;

[0008] The lifting drive assembly is installed on a pair of the supporting bases, and the lifting drive assembly includes a pair of supporting frames, the pair of supporting frames are respectively fixed on a pair of the supporting bases, an upper fixed crossbeam is fixedly connected between the pair of supporting frames, a lifting sleeve is slidably connected to the supporting frames, and a driving screw is threadedly connected to the lifting sleeve;

[0009] The lifting support assembly is installed between a pair of supporting frames, and the lifting support assembly includes a lower lifting beam, and both ends of the lower lifting beam are respectively fixedly connected to a pair of lifting sleeves. A plurality of grouting sleeves are arranged between the lower lifting beam and the supporting frames, and both ends of the grouting sleeves are fixedly connected to supporting steel bars.

[0010] In one or more embodiments of the utility model, a pair of limiting plates are fixed on the upper part of the supporting frame to provide limiting protection for the lifting sleeve. A sliding groove matching the limiting plates is bored on the lifting sleeve, so that the lifting sleeve is less likely to tilt during lifting and moving, thereby improving the stability of the device.

[0011] In one or more embodiments of the present invention, fixed bearings are fixedly connected between the two ends of the driving screw and the support base and the upper fixed beam, so that the driving screw is not easy to fall off, and the rotation of the driving screw is not easily affected by the support base or the upper fixed beam, thereby ensuring the stability of the rotation of the driving screw and achieving the effect of stably driving the lifting sleeve to rise and fall.

[0012] In one or more embodiments of the utility model, a cross groove is formed at one end of the driving screw away from the supporting base, so that the workers can rotate the driving screw by using tools, thereby reducing the pressure on the workers.

[0013] In one or more embodiments of the utility model, a plurality of lower clamps are fixed on the lower lifting beam, which are used to clamp the supporting steel bars connected below the grouting sleeve, thereby fixing the grouting sleeve and preventing the grouting sleeve from shaking or tilting. A plurality of extruding semicircular balls are fixed on the lower clamps, so that the lower clamps can be lifted and moved, thereby facilitating the lifting and moving of the lower lifting beam.

[0014] In one or more embodiments of the utility model, a plurality of upper clamps are fixed on the upper fixed cross beam, which are used to fix the supporting steel bars connected to the upper end of the grouting sleeve to achieve the effect of fixing the grouting sleeve. An arc-shaped clamp is fixed on the upper clamp, which makes it difficult for the supporting steel bars to slide, thereby improving the fixing effect.

[0015] In one or more embodiments of the present invention, the lower fixture and the upper fixture are both threadedly connected with fixing bolts for fixing the lower fixture and the upper fixture to the lower lifting beam and the upper fixed beam respectively.

[0016] Compared with the prior art, the utility model provides a corresponding mechanism so that the grouting sleeve and the connected steel bars can still be quickly adjusted in position after being fixed, thereby improving the assembly efficiency of the device and reducing the pressure on the staff.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] like Figure 1-Figure 4 As shown, a steel bar connection grouting sleeve bracket in one embodiment of the utility model includes: a pair of support bases 1, a lifting drive assembly 2 and a lifting support assembly 3.

[0026] like Figure 1-Figure 2As shown, the lifting drive assembly 2 is installed on a pair of support bases 1, and the lifting drive assembly 2 includes a pair of support frames 201 to provide support force for the device, and the pair of support frames 201 are respectively fixed on a pair of support bases 1. An upper fixed beam 202 is fixedly connected between the pair of support frames 201, and a lifting sleeve 203 is slidably connected on the support frame 201 to drive the lower lifting beam 301 to move up and down, thereby improving the applicability of the device.

[0027] Specifically, a driving screw 204 is threadedly connected to the lifting sleeve 203 to drive the lifting sleeve 203 to move up and down, thereby driving the lower lifting beam 301 to move up and down.

[0028] like Figure 1 As shown, a pair of limiting plates 205 are fixed on the support frame 201 to provide limiting protection for the lifting sleeve 203. The lifting sleeve 203 is provided with a sliding groove matching the limiting plates 205, so that the lifting sleeve 203 is not prone to tilting during lifting and moving, thereby improving the stability of the device.

[0029] In addition, fixed bearings 206 are fixedly connected between the two ends of the driving screw 204 and the support base 1 and the upper fixed beam 202, so that the driving screw 204 is not easy to fall off, and the rotation of the driving screw 204 is not easily affected by the support base 1 or the upper fixed beam 202, thereby ensuring the stability of the rotation of the driving screw 204, and then achieving the effect of stably driving the lifting sleeve 203 to rise and fall.

[0030] like Figure 1 As shown, a cross groove is bored at one end of the driving screw 204 away from the support base 1, so that the worker can use a tool to rotate the driving screw 204, thereby reducing the pressure on the worker. Preferably, the worker can connect the top ends of a pair of driving screws 204 to a driving device, and drive the driving screws 204 to rotate through the driving device, thereby reducing the pressure on the worker.

[0031] like Figure 1-Figure 2 As shown, the lifting support assembly 3 is installed between a pair of supporting frames 201, and the lifting support assembly 3 includes a lower lifting beam 301, and both ends of the lower lifting beam 301 are fixedly connected to a pair of lifting sleeves 203 respectively, and a plurality of grouting sleeves 302 are arranged between the lower lifting beam 301 and the supporting frames 201, and both ends of the grouting sleeves 302 are fixedly connected to supporting steel bars 303.

[0032] like Figure 1-Figure 4As shown, a plurality of lower clamps 304 are fixed on the lower lifting beam 301, which are used to clamp the supporting steel bars 303 connected below the grouting sleeve 302, so as to fix the grouting sleeve 302 and prevent the grouting sleeve 302 from shaking or tilting. A plurality of extruding semicircular balls 307 are fixed on the lower clamps 304, so that the lower clamps 304 can be lifted and moved, thereby facilitating the lifting and moving of the lower lifting beam 301.

[0033] like Figure 4 As shown, a plurality of upper clamps 305 are fixed on the upper fixed beam 202, which are used to fix the supporting steel bars 303 connected to the upper end of the grouting sleeve 302, thereby achieving the effect of fixing the grouting sleeve 302. An arc-shaped clamp 308 is fixed on the upper clamp 305, so that the supporting steel bars 303 are not prone to sliding, thereby improving the fixing effect.

[0034] Wherein, fixing bolts 306 are threadedly connected to the lower fixture 304 and the upper fixture 305, which are used to fix the lower fixture 304 and the upper fixture 305 to the lower lifting beam 301 and the upper fixed beam 202 respectively.

[0035] During specific use, when it is necessary to adjust the positions of the lower lifting beam 301 and multiple lower clamps 304, the staff uses a tool to rotate a pair of drive screws 204 or connects the drive screws 204 to a drive device, and drives the pair of drive screws 204 to rotate through the drive device, so that the drive screws 204 can drive the lifting sleeves 203 to move up and down, and the pair of lifting sleeves 203 will drive the lifting and moving of the lower lifting beam 301. At this time, since the multiple extruded semi-circular balls 307 are hemispherical, the lower clamps 304 are convenient to lift and move, and it is not easy to reduce the fixing effect of the supporting steel bars 303, thereby realizing the adjustment of the height of the lower lifting beam 301, providing convenience for the staff.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
