Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a jacking horizontal jack tensioning steel strand steering device. Background Art

[0002] Guide support frames, as an indispensable auxiliary equipment in on-site construction, are usually constructed of steel materials to provide a stable and reliable temporary platform for various construction operations. Traditional guide support frames are mostly triangular frame structures, which are made by welding three steel components together. Although this structural form is simple, it seems to be inadequate in certain specific construction environments.

[0003] During the steel beam jacking construction, the movement process of the steel strands puts higher requirements on the guide support frame. The traditional guide support frame has a single structure and lacks an effective guiding mechanism, and is unable to control the movement trajectory of the steel strands, which greatly affects the construction efficiency and quality. At the same time, considering the construction cost, the design of the guide support frame needs to comprehensively consider multiple factors and meet the characteristics of simple manufacturing, detachable and easy installation, so as to quickly adapt to different construction environments and needs.

[0004] In view of this, we propose a horizontal jack-type steel strand tensioning steering device. Utility Model Content

[0005] The purpose of the utility model is to provide a horizontal jack-type steel strand tensioning steering device which is simple to manufacture, detachable, and easy to install and can control the movement trajectory of the steel strand, so as to solve the problems raised in the above-mentioned background technology.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, this embodiment provides a steering device for tensioning steel strands with a horizontal jack for pushing, including a bogie 100. Considering the weight of the steel strands, the bogie 100 includes a triangular support group 110 for support. Considering the convenience of controlling the downward direction of the steel strands, a guide group 120 for controlling the direction of the steel strands is provided above the support group 110.

[0024] The improvement of this embodiment is that when the bogie 100 is used, the steel strands are moved downward to drive the round steel support crossbar 121 to rotate, thereby controlling the downward movement direction of the steel strands and improving the construction efficiency.

[0025] like Figure 2 - Figure 3 As shown, in order to strengthen the fixation of the support group 110 and prevent the steel strands from exerting pressure on the support group 110 and destroying the overall structure of the support group 110, the support group 110 includes two support columns 112, diagonal braces 114 for diagonally supporting each support column 112, a base 111 and a horizontal crossbar connection system 113, wherein the horizontal crossbar connection system 113 is welded and fixed between the two support columns 112 to increase the stability of the force transmission structure, the support columns 112, the base 111 and the diagonal braces 114 are welded and fixed to each other, and the base 111 is fixed to the operating platform by bolts, and the load of the steel strands on the round steel support crossbar 121 is transmitted to the operating platform through the support columns 112, the diagonal braces 114 and the base 111.

[0026] At the same time, in order to avoid friction between the round steel support cross bar 121 and the support column 112, which makes it difficult to drive the round steel support cross bar 121 to rotate when the steel strand moves downward, the guide group 120 includes a rotatable round steel support cross bar 121 and a thick-walled steel casing 123, wherein the thick-walled steel casing 123 is respectively sleeved on both ends of the round steel support cross bar 121, and a vertical slot is provided on the top of the support column 112, and the thick-walled steel casing 123 is clamped in the vertical slot on the top of the support column 112. The thick-walled steel casing 123 is used to prevent the round steel support cross bar 121 from directly contacting the support column 112, thereby reducing friction. At the same time, the thick-walled steel casing 123 can also play a guiding and vibration reducing role during the movement of the steel strand.

[0027] It should be further explained that the base 111, supporting columns 112, horizontal cross bar connection system 113, diagonal braces 114, round steel supporting cross bars 121, limiting steel plates 122, thick-walled steel casing 123 and bolts can all use dismantled old materials, such as I-beams, angle steels, steel plates, etc., so as to improve material utilization and save materials; the number of supporting columns 112, horizontal cross bar connection system 113, diagonal braces 114, limiting steel plates 122 and thick-walled steel casing 123 are all two.

[0028] In summary, the working principle of this scheme is as follows Figure 4 As shown:

[0029] The two thick-walled steel sleeves 123 are respectively sleeved on the two ends of the round steel support cross bar 121 to form a guide group 120, and the base 111 is fixed to the push platform with bolts. Two I-beams are taken out to make support columns 112. One end of the support column 112 is welded and fixed to the base 111, and a groove is provided at the other end of the support column 112 on its web. The thick-walled steel sleeves 123 at both ends of the guide group 120 are then clamped into the grooves of the support column 112. Then, the limiting steel plate 122 is taken out and welded at the upper flange of the support column 112. Two angle steels are taken out to make diagonal braces 114. The two ends of the diagonal braces 114 are welded to the base 111 and the support column 112 respectively. Then, two more I-beams are taken out to make support columns 112. An angle steel is used to make a horizontal cross bar connection system 113, and both ends of each horizontal cross bar connection system 113 are welded and fixed to two supporting columns 112, and the installation of the bogie 100 is completed. One end of the steel strand is passed through the steel beam and the jack at one time, and the other end of the steel strand is placed above the round steel supporting cross bar 121. The jack is a ZLD3500 jack. When the jack performs hydraulic movement and the steel beam is pushed upward by the steel strand, one end of the steel strand close to the round steel supporting cross bar 121 is gradually pushed out, and under the action of gravity, the steel strand at one end of the round steel supporting cross bar 121 moves downward, and at the same time drives the round steel supporting cross bar 121 to rotate, thereby realizing the control of the moving direction of the steel strand.

[0030] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0031] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
