Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to a simple device for straightening steel bars at a construction site. Background Technique

[0002] At present, simple steel bar wrenches are used for straightening small-diameter steel bars in China, and hydraulic straightening equipment produced by professional manufacturers is used for straightening large-diameter steel bars. However, during the on-site construction process, steel bars are often straightened when facing emergencies. At this time, special straightening equipment needs to be purchased.

[0003] The prior art 201921314930.9 discloses a steel bar straightening machine with high straightening accuracy, including a protective shell, a first transmission component, a second transmission component, a straightening component, and a control component. The straightening component includes a fixing plate, which is fixed on two opposite faces of the protective shell. There is a push rod at each end of the fixing plate relative to the transmission gear. The end of the push rod away from the fixing plate is fixedly connected to a pushing component. The pushing component includes a pushing roller and a connecting rod. The connecting rod fixedly connects the two ends of the pushing rollers arranged in the same direction on the same horizontal line in sequence to form a whole. Although the above prior art reduces the intensity of manual operation and also improves the straightening accuracy, during the construction process of some remote mountainous area projects, falling stones or other special situations will cause impact deformation to the steel bars that have been tied. Due to the large diameter of the steel bars, manual straightening is impossible, and it takes a long time for the above-mentioned prior art or other finished straightening equipment to arrive at the site, which will affect the on-site construction and prolong the construction period. Content of the Utility Model

[0004] The utility model aims to solve the above problems, and thus provides a simple device for straightening steel bars at a construction site that can be made on-site.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] A simple device for straightening steel bars at a construction site includes a main beam. Support beams are obliquely fixed on both sides of the bottom of the main beam. A jack is vertically arranged in the middle of the bottom surface of the main beam. An extrusion block is arranged at the bottom end of the jack. Long strip holes are oppositely opened longitudinally at the middle positions of the lower parts of the two support beams. Limited position mechanisms that can move horizontally are oppositely arranged on the opposite surfaces of the two support beams and on both sides of the long strip holes.

[0007] The utility model adopting the above technical solution, compared with the prior art, has the following prominent features:

[0008] Pass the bent steel bar through two long strip holes, limit the left and right of the steel bar through the limiting mechanism to prevent the steel bar from shifting. The jack drives the extrusion block to press down, so that the steel bar is adjusted from a bent state to a straight state. The materials used for the main beam, support beam and jack can be obtained locally at the construction site. The overall structure is simple and practical, which can ensure the smooth progress of the construction period.

[0009] As a preference, a further technical solution of the present utility model is:

[0010] Furthermore, a connecting rod is provided between the sides of the two support beams.

[0011] Furthermore, the extrusion block is in a groove shape with the opening facing downwards, and the opening width of the extrusion block is adapted to the steel bar.

[0012] Furthermore, the limiting mechanism includes positioning plates that are relatively welded on the support beam and located on both sides of the long strip hole. Limiting holes are relatively opened on the two positioning plates. Nuts are respectively fixed on the positioning plates and on both sides of the limiting holes. A screw rod passes through the nut and the limiting hole together. A limiting plate is welded to the inner end of the screw rod.

[0019] The following further illustrates the present utility model in conjunction with embodiments. The purpose is only to better understand the content of the present utility model. Therefore, the examples given do not limit the protection scope of the present utility model.

[0020] A simple device for straightening steel bars at the construction site, including a main beam 1. On both sides of the bottom of the main beam 1, support beams 2 are obliquely fixed. In the middle of the bottom surface of the main beam 1, a jack 3 is vertically arranged. At the bottom end of the jack 3, an extrusion block 4 is arranged. At the middle position between the lower parts of the two support beams 2, long holes are oppositely opened longitudinally. On the opposite surfaces of the two support beams 2 and on both sides of the long holes, limited position mechanisms that can move horizontally are oppositely arranged.

[0021] Furthermore, a connecting rod 5 is arranged between the side surfaces of the two support beams 2, and the connecting rod 5 plays a role in connecting and strengthening between the support beams 2.

[0022] Furthermore, the extrusion block 4 is in a groove shape with the opening facing downwards. The opening width of the extrusion block 4 is adapted to the steel bar 11. The extrusion block 4 limits the transverse direction of the steel bar 11 at the extruded part.

[0023] Furthermore, the limited position mechanism includes positioning plates 6 that are oppositely welded on the support beams 2 and on both sides of the long holes. The positioning plates 6 can be made of steel plates used on-site. Oppositely opened limited position holes are arranged on the two positioning plates 6. Nuts 7 are respectively fixed on both sides of the positioning plates 6 and at the limited position holes. A screw rod 8 penetrates through the nuts 7 and the limited position holes together. At the inner end of the screw rod 8, a limited position plate 9 is welded. The limited position plate 9 does not contact the support beam 2. By rotating the screw rod 8, the limited position plate 9 is driven to move relatively to limit both sides of the steel bar 11 and prevent the steel bar 11 from generating offset.

[0024] Furthermore, a hand crank 10 is arranged at the outer end of the screw rod 8, and it is easier to control the screw rod 8 by using the hand crank 10.

[0025] Furthermore, both the main beam 1 and the support beams 2 are made of channel steel. The opening of the main beam 1 faces upwards, and the opening of the support beams 2 faces inwards, which is easier to obtain raw materials at the construction site.

[0026] Pass the bent steel bar through the two long holes, limit the left and right of the steel bar through the limited position mechanism to prevent the steel bar from generating offset. The jack drives the extrusion block to press down, so that the steel bar is adjusted from the bent state to the straight state. The materials used for the main beam, the support beams, and the jack can be obtained locally at the construction site. The overall structure is simple and practical, which can ensure the smooth progress of the construction period.

[0027] The above are only the preferred and feasible embodiments of the present utility model, and thus do not limit the scope of rights of the present utility model. All equivalent changes made by using the content of the specification and drawings of the present utility model are included within the scope of rights of the present utility model.
