[0029] Combine the following Figure 1 to Figure 4 The embodiment shown describes the technical solution of the utility model:

[0030] The utility model provides a multifunctional load-unloading and leveling device, comprising: a core-penetrating embedded part 1; a wedge box 2, comprising an upper wedge block 201 and a lower wedge block 202, the upper wedge block 201 and the lower wedge block 202 are both trapezoidal structures, and the lower wedge block 202 is relatively slidably arranged with an inclined edge of the upper wedge block 201; a core-penetrating hole 3, which is penetrated and opened in the lower wedge block 202, and the end of the core-penetrating embedded part 1 exposed from the building passes through the core-penetrating hole 3.

[0031] It can be understood that the utility model provides a multifunctional load-unloading and leveling device, which serves as the main load-bearing supporting structure. When the building equipped with the multifunctional load-unloading and leveling device is affected by gravity, the pressure is transmitted to the multifunctional load-unloading and leveling device, which has a buffering effect. The multifunctional load-unloading and leveling device designed by the utility model has low construction difficulty, fast construction speed and low cost.

[0032] The multifunctional load-unloading and leveling device provided by the utility model comprises a core-penetrating embedded part 1, which has a certain load-bearing capacity. One end of the core-penetrating embedded part 1 is pre-fixed inside the building. The core-penetrating embedded part 1 is pre-set in the pier column during the construction of the pier tie beam or the cap beam. The shape of the core-penetrating embedded part 1 is selected to be a regular shape, which is convenient for fixing the wedge box 2 at the position of the core-penetrating embedded part 1. The specific position of the core-penetrating embedded part 1 is selected according to actual conditions.

[0033] The wedge box 2 includes an upper wedge block 201 and a lower wedge block 202. Both wedge boxes 2 are trapezoidal structures. One of the hypotenuses of the trapezoid cooperates with each other. One hypotenuse of the upper wedge block 201 is set corresponding to one hypotenuse of the lower wedge block 202, but the two hypotenuses are not connected, and relative sliding can occur. The lengths of the two bottom sides of the upper wedge block 201 and the lower wedge block 202 are selected according to actual needs. The other hypotenuse of the upper wedge block 201 needs to contact the main beam for the main beam, and the lower wedge block 202 needs to pass through the through-core embedded part 1 to provide the main supporting force. Therefore, the lengths of the bottom sides of the upper wedge block 201 and the lower wedge block 202 can be obtained by pouring concrete after the size is determined according to actual conditions. If the height of the main beam changes after the size of the wedge box 2 is designed, a load-bearing block of a specified height can be placed above the other hypotenuse of the upper wedge block 201, thereby improving the versatility of the wedge box 2.

[0034] The through hole 3 is penetrated through the lower wedge block 202, and the end of the through hole 3 exposed from the building passes through the through hole 3. The shape of the through hole 3 matches the through hole 3. The through hole 3 passes through the through hole 3 and is fixed in the through hole 3, so as to achieve the purpose of determining the position of the wedge box 2. When working, the through hole 3 also serves as the main force-bearing support structure.

[0035] Figure 1 An example of a multifunctional load-unloading and leveling device with a specific structure is given. It can be seen that the core-penetrating embedded part 1 is a cylinder, one end of which is fixedly arranged on one side of the building. A position is reserved in advance for setting the core-penetrating embedded part 1 at the pier, and some steel mesh is added to the concrete when pouring the core-penetrating embedded part 1. The pouring and molding is carried out after the concrete strength of the core-penetrating embedded part 1 reaches the design strength.

[0036] The upper wedge block 201 and the lower wedge block 202 are designed as right-angled trapezoids, and the length and angle of the hypotenuses of the two right-angled trapezoids are the same. After the two hypotenuses of the upper wedge block 201 and the lower wedge block 202 are relatively slidably arranged, the entire wedge box 2 presents a rectangle, and the length of the right-angled hypotenuse of the lower wedge block 202 is greater than the diameter of the core-through embedded part 1, which is convenient for opening the core-through hole 3 on the lower wedge block 202. The length of the right-angled hypotenuse of the upper wedge block 201 is the same as that of the lower wedge block 202, which ensures that the contact area between the two hypotenuses is maximized. At the same time, a rectangle can be formed between the upper wedge block 201 and the lower wedge block 202 in the initial state, thereby improving the aesthetics of the entire device.

[0037] The through hole 3 is opened through the middle position of the lower wedge block 202 to avoid a certain degree of tilt caused by uneven weight of the lower wedge blocks 202 on both sides of the through hole 3, so as not to affect the subsequent placement of the main beam. The end of the through hole embedded part 1 exposed from the building passes through the through hole 3, and the through hole embedded part 1 is fixedly connected to the lower wedge block 202 through the through hole 3. The hypotenuse of the lower wedge block 202 is placed upward, and the two bottom edges are respectively located on the left and right sides, and the right-angled hypotenuse is located at the bottom. After the lower wedge block 202 is fixed on the through hole embedded part 1, the hypotenuse of the upper wedge block 201 is slid and set above the hypotenuse of the lower wedge block 202, and the right-angled hypotenuse of the upper wedge block 201 is located at the top. After the entire device is installed, it contacts the bottom surface of the main beam.

[0038] The shape of the through hole 3 is square, and the side length of the through hole 3 matches the diameter of the through embedded part 1 , so that the through embedded part 1 can pass through the through hole 3 , thereby fixing the wedge box 2 at the position of the through embedded part 1 .

[0039] The multifunctional unloading and leveling device provided by the utility model reduces the difficulty and cost of unloading and leveling construction, is applicable to a wide range of working conditions, improves construction speed and ensures construction safety.

[0040] According to the multifunctional load-relief leveling device provided by the utility model: a sliding through hole 4 is formed through the relative arrangement positions of the upper wedge block 201 and the lower wedge block 202 , and a screw rod 5 is arranged in the sliding through hole 4 .

[0041] In the utility model, a sliding through hole 4 is provided at the relative arrangement position of the upper wedge block 201 and the lower wedge block 202. The sliding through hole 4 penetrates the relative sliding position of the upper wedge block 201 and the lower wedge block 202. The left end of the sliding through hole 4 is opened at the long bottom side of the lower wedge block 202, and the right end of the sliding through hole 4 is opened at the long bottom side of the upper wedge block 201. The through hole is a continuous linear through hole. A screw 5 is provided in the sliding through hole 4. The length of the screw 5 is greater than the length of the right-angled hypotenuse of the wedge box 2. The screw 5 is passed through the sliding through hole 4 to connect the upper wedge block 201 and the lower wedge block 202 together. When the right-angled side of the upper wedge block 201 contacts the main beam and is subjected to force, the upper wedge block 201 and the lower wedge block 202 slide relative to each other along the sliding through hole 4, thereby achieving the effect of unloading and leveling.

[0042] According to the multifunctional unloading and leveling device provided by the utility model: the length of the screw rod 5 is greater than the depth of the sliding through hole 4, the width of the sliding through hole 4 matches the diameter of the screw rod 5, and the length of the sliding through hole 4 is greater than the diameter of the screw rod 5.

[0043] In the utility model, the sliding through hole 4 is a groove-shaped hole, the length of the screw 5 of the sliding through hole 4 is greater than the depth of the sliding through hole 4, the width of the sliding through hole 4 is matched with the diameter of the screw 5, and the length of the sliding through hole 4 is greater than the diameter of the screw 5, that is, the screw 5 can slide up and down in the sliding through hole 4. When the device is working, the upper wedge block 201 slides to the lower right, and the position of the screw 5 does not move. Therefore, it is necessary to set a groove-shaped sliding through hole 4 to facilitate the upper wedge block 201 to slide to the lower right to achieve the effect of unloading and leveling.

[0044] According to the multifunctional unloading and leveling device provided by the utility model: nuts 6 are respectively arranged at both ends of the sliding through hole 4, and the nuts 6 are threadedly connected with the screw rod 5 to fix the screw rod 5 in the sliding through hole 4.

[0045] In the present invention, nuts 6 are respectively provided at both ends of the sliding through hole 4. The shape of the nut 6 is an inverted T-shaped nut. The distance between the nut 6 and the screw rod 5 is relatively long, which can improve the stability of the nut 6. The nut 6 is threadedly connected to the screw rod 5. The two-point function of the nut 6 is to fix the screw rod 5 in the sliding through hole 4. When the upper wedge block 201 is subjected to force, the upper wedge block 201 slides relatively, and the screw rod 5 does not move. When the upper wedge block 201 slides, the nut 6 generates corresponding resistance to the upper wedge block 201, ensuring that the sliding of the upper wedge block 201 is within a certain range, avoiding that the sliding range of the upper wedge block 201 is too large, and causing too much impact on the main beam, thereby ensuring the effect of unloading and leveling. If the two ends of the screw rod 5 are not limited and fixed, the upper wedge block 201 may slide and fall off, and the purpose of unloading and leveling cannot be achieved.

[0046] According to the multifunctional load-relief leveling device provided by the utility model: a fixed frame 7 is fixedly provided at one end of the lower wedge block 202 away from the building surface, the fixed frame 7 is arranged corresponding to the core hole 3, and a fixing nut 8 is arranged in a circumferential array on the fixed frame 7.

[0047] In the utility model, a fixed frame 7 is fixedly provided at one end of the lower wedge block 202 away from the building surface. The fixed frame 7 is arranged corresponding to the core hole 3 and is a square. The length of the four side frames of the fixed frame 7 is the same as the length of the core hole 3, and the right angles are connected by side lines. The fixed frame 7 is provided with a fixing nut 8 in a circular array. The fixed frame 7 has a certain width to facilitate the passing of the fixing nut 8. There are four fixing nuts 8, which are respectively arranged in the middle positions of the four sides of the fixed frame 7 and are arranged in a circular array. After the core embedded part 1 passes through the core hole 3, the fixing nuts 8 in four directions are tightened until the fixing nut 8 is close to one end of the core embedded part 1 and is in close contact with the core embedded part 1, so as to achieve the purpose of fixing the lower wedge plate.

[0048] The multifunctional load-unloading and leveling device provided by the utility model improves the load transfer to the main beam during the construction process. The main beam transfers the load to the pier column through the multifunctional load-unloading and leveling device, thereby completing the load system conversion. After the upper wedge block 201 and the lower wedge block 202 are cast and formed, the water sprinkling curing time is not less than seven days, thereby improving the strength of the wedge box 2.

[0049] The working principle of the utility model is as follows: when constructing a pier, a core-penetrating embedded part 1 is set at a designated position, the core-penetrating embedded part 1 is passed through the core-penetrating hole 3 of the lower wedge block 202, and the lower wedge plate is fixed at the position of the core-penetrating embedded part 1 by tightening four fixing nuts 8, ensuring that the upper side of the lower wedge plate is a bevel, and then the bevel of the upper wedge plate is placed corresponding to the bevel of the lower wedge plate, and then the screw rod 5 is passed through the sliding through hole 4, and the screw rod 5 is fixed in the sliding through hole 4 by the nut 6. When the upper wedge plate receives the force transmitted by the main beam, relative sliding occurs between the upper wedge plate and the lower wedge plate, but the sliding amplitude is prevented from being too large under the action of the nut 6, and then the force is transmitted to the pier, thereby achieving the purpose of unloading and leveling, and the device has low construction difficulty and low cost, and can ensure construction safety while improving construction speed.

[0050] The multifunctional load-unloading and leveling device provided by the utility model can support and act on a steel rod or a rectangular plane. When acting on the steel rod, a through-core steel rod is set by means of pre-reserving or pre-embedding on the surface of the building, and a through-core hole 3 is opened on the lower wedge block 2022. The steel rod inserted into the through-core hole 3 is fixed in position by a fixing nut 8 to prevent it from tipping over. Then, the upper wedge block 2012 and the lower wedge block 2022 are slidably connected by a screw rod 5. By adjusting the tightness of the nut 6, the upper wedge block 2012 and the lower wedge block 2022 are made to slide relative to each other, thereby achieving the purpose of load-unloading and leveling. When acting on a rectangular plane, the bottom surface of the lower wedge block 2022 is used as a bearing surface. Similarly, by adjusting the tightness of the nut 6, the upper wedge block 2012 and the lower wedge block 2022 are made to slide relative to each other, thereby achieving the purpose of load-unloading and leveling.

[0051] The device of the invention is applicable to a variety of working conditions and is used to solve the technical problems in the prior art such as the difficulty, high cost, limited applicability, long construction period and high construction risk of unloading and leveling construction. It achieves the purpose of reducing the difficulty and cost of unloading and leveling construction, being applicable to a wide range of working conditions, increasing construction speed and ensuring construction safety.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
