Description

Technical Field

[0001] The utility model relates to the technical field of tension screw rod control, in particular to a tension screw rod control tooling for a thin-walled hollow multi-curved plain concrete wooden formwork. 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] However, when faced with irregular formwork, the installation of the tie screws is still arranged in a horizontal array, which results in different angles of inclination between each tie screw and the formwork, as well as different lengths of the tie screws inside the formwork. Especially when the formwork is made of wood, the wood itself is a flexible material, and the tie screws are subjected to heavy force, which will cause the clear water plug to sink; when the tie screws are subjected to light force, it will cause the clear water plug to bulge out; when pouring concrete, the lateral pressure on the tie screws will also be different, presenting an irregular state, and it is impossible to better control the effect of the clear water concrete wood formwork according to the irregular conditions on site.

[0026] Reference Figure 1-Figure 4 As shown, a thin-walled hollow multi-curved exposed concrete wooden formwork tension screw control tooling includes:

[0027] Two mounting plates 1 are respectively sleeved on both ends of the tensioning screw rod 6;

[0028] The first length measuring assembly 2 and the second length measuring assembly 5 are respectively arranged on the two mounting plates 1, and are used to measure the length of the tension screw 6 exposed outside, and the structure of the second length measuring assembly 5 is the same as that of the first length measuring assembly 2;

[0029] When installing the tension screws 6, the tension screws 6 are arranged horizontally and at equal distances. After being inserted into the wooden mold, the length of each tension screw 6 inside the wooden mold is different, and a certain angle is formed between each tension screw 6 and the wooden mold. This makes the torque required for each tension screw 6 different. Therefore, it is necessary to measure these data and calculate the torque.

[0030] First, when installing the tension screw 6, the length of the tension screw 6 is longer than the width of the wood mold, and its two ends extend out of the wood mold, and the total length of the tension screw 6 is determined. At this time, the length between the two ends of the tension screw 6 and the outer wall of the wood mold can be measured by the length measuring components at both ends, and then the length of the tension screw 6 inside the wood mold can be determined;

[0031] An angle measuring component 3, arranged on the first length measuring component 2, is used to measure the angle between the tension screw 6 and the wooden mold;

[0032] The terminal 4 is arranged on the mounting plate 1, and is used to calculate the torque required for the tension screw 6. After obtaining the length of the tension screw 6 inside the wooden mold and the angle between the tension screw 6 and the wooden mold, these data can be input into the terminal 4 to calculate the torque required for the tension screw 6, and then the tension screw 6 can be installed by using a torque wrench.

[0033] In one embodiment, the first length measuring component 2 includes a telescopic rod 21 inserted on the mounting plate 1, one end of the telescopic rod 21 is provided with a fixed handle 22, the angle measuring component 3 is provided at the other end of the telescopic rod 21, and the telescopic rod 21 is provided with a scale;

[0034] The telescopic rod 21 can be pushed manually so that it is pressed against the wooden mold, and then the remaining length of the end of the tension screw 6 can be read according to the scale. The length of the tension screw 6 inside the wooden mold can be obtained by subtracting the elongation at both ends from the total length of the tension screw 6.

[0035] In one embodiment, a first fixing frame 24 is provided on one side of the mounting plate 1, a driving gear 23 is rotatably provided in the first fixing frame 24, a small motor for electric drive is provided on one side of the driving gear 23, a tooth groove matching with the driving gear 23 is provided on the telescopic rod 21, a support rod 25 is provided on the other end of the mounting plate 1, a limit slider 26 is provided on the support rod 25, and a slide groove matching with the limit slider 26 is provided on the telescopic rod 21;

[0038] When the telescopic rod 21 moves forward, it will press against the outer wall of the wooden mold, and the angle mark rod 33 will deflect after contacting the wooden mold and become tangent to the curved surface of the wooden mold. At this time, the angle between the tension screw 6 and the wooden mold can be obtained by the protractor 35.

[0039] In one embodiment, a guide rod 32 is disposed at one end of the movable block 31 away from the angle mark rod 33 , and a guide groove matched with the guide rod 32 is provided in the telescopic rod 21 .

[0040] In one embodiment, a movable groove is provided on the telescopic rod 21, a slide bar 211 is provided in the movable groove, a movable slider 311 sleeved on the slide bar 211 is fixedly provided on the movable block 31, and a return spring 212 sleeved on the slide bar 211 is provided between the movable slider 311 and the inner side wall of the movable groove;

[0041] When the telescopic rod 21 pushes the movable block 31 and the angle mark rod 33 contacts the wooden mold, the movable block 31 will shrink backwards to allow the guide rod 32 to be inserted into the guide groove. At the same time, the movable block 31 will also drive the moving slider 311 to squeeze the return spring 212, and the return spring 212 will be used to buffer the movable block 31.
