Description

Technical Field

[0001] The utility model relates to the technical field of tension screw rods, in particular to a tension screw rod assembly for a thin-walled hollow multi-curved plain concrete steel mould. Background Art

[0002] The tension screws are used to tie the inner and outer formworks of the wall, bearing the lateral pressure of the concrete and other loads to ensure that the spacing between the inner and outer formworks meets the design requirements. They are also the fulcrum of the formwork and its supporting structure. Therefore, the arrangement of the tension screws has a great influence on the integrity, rigidity and strength of the formwork structure.

[0003] At present, in many projects, the walls of many buildings adopt special-shaped structures, and the walls are mostly composed of curved surfaces. In the process of pouring plain concrete, curved steel molds are usually used, and steel meshes are set between two steel molds. Extruded plates are set on the inner walls of the steel molds. In order to fix the steel molds, tension screws are also required on the steel molds. The existing tension screws have a simple structure, are usually integrally formed, cannot be adjusted, and cannot fix the steel mesh inside the steel mold. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] Reference Figure 1 and Figure 2As shown, the inner layer of the curved steel mold 5 is filled with an extruded board 7, and the outer layer of the extruded board 7 is provided with a steel mesh 6. The tensioning screw body 1 is distributed in an array along the horizontal direction, inserted on the steel mold 5, and passes through the installed steel mesh 6 and the extruded board 7, and penetrates from the other side. When setting the tensioning screw body 1, it is necessary to position the steel mesh 6 through the tensioning screw body 1; although the extruded board 7 can be fixed by the steel mold 5, the extruded board 7 will still undergo an overall offset during pouring. Therefore, it is also necessary to position the extruded board 7 through the tensioning screw body 1.

[0030] Reference Figure 3-Figure 6 As shown, a thin-walled hollow multi-curved plain concrete steel mold tie screw assembly includes a tie screw body 1, the length of the tie screw body 1 itself is adjustable, and also includes:

[0031] The telescopic assembly 2 is arranged on the tension screw body 1 and is used to adjust the length of the tension screw body 1;

[0032] Two sets of fixing components 3 are arranged on the tension screw body 1 and are used to support the steel mesh 6;

[0033] Two sets of clamping components 4 are arranged on the tensioning screw body 1 and are used to position the extruded plate 7.

[0034] In one embodiment, the tension screw body 1 includes a tension rod 11, and both ends of the tension rod 11 are sleeved with a pull rod 12, the telescopic assembly 2, the fixing assembly 3 and the clamping assembly 4 are all arranged on the two pull rods 12, and the end of the pull rod 12 away from the tension rod 11 is also provided with a locking rod 13, and the pull rod 12 is also sleeved with a clear water plug 14 that is tightly against the inner wall of the steel mold 5;

[0035] After determining the distance between the two steel molds 5, the length of the tension screw body 1 can be adjusted, and the pull rods 12 at both ends can be pushed to move to both sides through the telescopic component 2, so that the pull rods 12 can pass through the extruded plate 7 and stick to the steel mold 5, and then the locking rod 13 can be inserted on the outside of the steel mold 5 toward the pull rod 12, and the steel mold 5 can be fixed with the outer clamp; and the internal clean water plug 14 can be close to the inner wall of the steel mold 5.

[0036] In one embodiment, the telescopic assembly 2 includes two mounting blocks 21, and the two mounting blocks 21 are respectively arranged on the two pull rods 12, and a first bidirectional threaded rod 22 is arranged between the two mounting blocks 21;

[0037] When adjusting the tension screw body 1 , the first bidirectional threaded rod 22 is rotated so that the mounting blocks 21 at both ends simultaneously move in opposite directions, thereby completing the adjustment of the length of the entire tension screw body 1 .

[0038] In one embodiment, the fixing assembly 3 includes a collar 31 sleeved on the tension screw body 1, and the collar 31 is provided with an adjusting assembly 32 around it. A clamping assembly 2 33 for clamping the steel mesh 6 is provided on one side of the adjusting assembly 32 away from the collar 31;

[0039] The fixing component 3 can slide on the tension screw body 1, and the fixing component 3 is installed on the tension rod 11 and the pull rod 12 at the same time. The adjusting component 32 can adjust the height and angle of the clamping component 33 to facilitate the clamping of the steel mesh 6.

[0040] In one embodiment, the adjustment component 32 includes a fixed sleeve 321 fixed on the ring 31, a lifting rod 322 is movably provided in the fixed sleeve 321, and a ball joint 323 connected to the clamping component 2 33 is provided at one end of the lifting rod 322.

[0041] In one embodiment, a vertical groove is formed on the side wall of the fixed sleeve 321, a lead screw 324 is rotatably disposed in the vertical groove, one end of the lead screw 324 passes through the fixed sleeve 321 and is connected to a gear 325, a limiting slider 326 sleeved on the lead screw 324 is fixedly disposed on the lifting rod 322, and a driving ring 327 meshing with the gear 325 is rotatably disposed on the top of the fixed sleeve 321;

[0042] By rotating the drive ring 327, the drive ring 327 can drive the lead screw 324 to rotate through the gears 325 on both sides, thereby driving the lifting rod 322 to perform lifting movements through the limit slider 326; since the tension screw body 1 is horizontally distributed at a certain interval, and the steel mesh 6 in the steel mold 5 is set at multiple angles, the ball joint 323 can change the angle of the clamping component 2 33, which is convenient for fixing and clamping the steel bars, providing a certain supporting force, and maintaining stability.

[0043] In one embodiment, the clamping component 33 includes a bracket 331 fixed on the ball joint 323, a second bidirectional threaded rod 332 is rotatably arranged in the bracket 331, and clamps 333 are sleeved on both ends of the second bidirectional threaded rod 332; first, the height and angle are adjusted by adjusting the component 32 so that the steel bar is located between the two clamps 333, and then the second bidirectional threaded rod 332 is rotated so that the clamps 333 can fix and clamp the steel bar.

[0044] In one embodiment, the clamping assembly 4 includes two clamping heads 41 sleeved on the pull rod 12, a connecting ring 42 is provided on one side of the clamping head 41, a positioning rod 43 is inserted on the connecting ring 42, and a plurality of positioning holes matching with the positioning rod 43 are opened on the pull rod 12;

[0045] Since the clamping head 41 itself is detachable, during installation, one is put on first, and then after the tensioning screw body 1 is inserted into the extruded plate 7, the other is put on the other side of the extruded plate 7. Then the two clamping heads 41 are moved toward the direction of the extruded plate 7 to fix and clamp the extruded plate 7. The clamping head 41 itself is larger than the inner diameter of the tensioning screw body 1. After clamping the extruded plate 7, it can be squeezed inward to block the gaps in the holes that may be left after the tensioning screw body 1 passes through, thereby preventing concrete from entering the extruded plate 7 through the gap during the pouring process; and after squeezing and clamping the extruded plate 7 inward, the positioning rod 43 can be tightened to fix the two clamping heads 41.

[0046] 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 basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, 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 are included in the present invention.
