Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a wall horizontal pressure applying device. Background Technique

[0002] China is vigorously promoting prefabricated buildings, among which precast concrete partition walls are widely used. Due to the technological characteristics of their installation and construction: the keyways between each partition wall and between the partition wall and the structural wall and column are filled with adhesives. During the construction process, it is easy to cause common quality problems such as cracking of the wall plaster layer due to poor quality of the bonding mortar, insufficient bonding mortar at the connection, premature removal of the partition wall wooden wedges, non-standard grooving of the water and electricity pipelines, too early time, and shrinkage of the components caused by temperature changes. Due to the new characteristics of prefabricated construction, the traditional methods for treating the common quality problems of surface cracking of the board joints have poor effects in actual construction. The existing wall horizontal pressure applying devices generally simply use jacks for extrusion, but when using them, the jacks need to be first supported to the designated position manually. Since the jacks themselves are not light in weight and need to be placed in a suitable position to achieve the best force application effect, it is quite cumbersome and inconvenient to support and position them only by manpower, which affects the work efficiency.

[0034] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0035] Embodiment 1:

[0036] A wall horizontal pressure applying device, as Figures 1-4 shown, includes a hand-operated jack 1. A first limit plate 2 is sleeved at one end of the hand-operated jack 1. A handle 3 is fixedly connected to the top of the first limit plate 2. A crank 4 is fixedly connected to one end of the hand-operated jack 1. Through the design of the hand-operated jack 1, the device can generate sufficient horizontal pressure, facilitating the staff to press the wall, realizing the pre-tightening of the wall, and then facilitating subsequent operations. At the same time, the first limit plate 2 and the handle 3 not only provide stable support for the device, but also enable the staff to conveniently carry and accurately position the device. The fixed connection of the crank 4 makes the force application process more stable and controllable, improving the operability and working efficiency of the entire device.

[0037] Refer to Figure 1 and Figure 2 , sliding plates 5 are slidably connected to both sides of the hand-operated jack 1. Springs 6 are arranged between the sliding plates 5 and the hand-operated jack 1. A plurality of the springs 6 are linearly and evenly arranged. Through the sliding plates 5 slidably connected to both sides of the hand-operated jack 1, the device can ensure a stable force application point by the contact of the sliding plates 5 with the wall before applying pressure, preventing the device from sliding or shifting during the force application process. At the same time, the arrangement of the springs 6 plays a buffering and adaptive role between the sliding plates 5 and the hand-operated jack 1, helping the device to adapt to walls with different flatness, ensuring that the sliding plates 5 can closely fit the wall, providing stable pressure output, and ensuring that the device can stably support on the wall before being pressed tightly.

[0038] The implementation principle of the present utility model is as follows: First, hold the handle 3 and place the hand-operated jack 1 at the designated position. At this time, the sliding plates 5 on both sides of the device are pushed by the springs 6 to press against the walls on both sides, enabling the device to be fixed in the current position. Then rotate the handle 3, and the handle 3 drives the hand-operated jack 1 to open, completing the effect of pressing the two sides of the wall tightly.

[0039] Embodiment Two:

[0040] Refer to Figure 3 and Figure 4 , a first bevel gear 7 is fixedly connected to one end of the hand-operated jack 1. A second bevel gear 8 is meshed with one side of the first bevel gear 7. Through the first bevel gear 7 fixed at one end of the hand-operated jack 1 and the second bevel gear 8 meshed with the first bevel gear, effective transmission and steering of power are realized. The design of the bevel gears enables the operator to drive the hand-operated jack by rotating the second bevel gear 8, thus more easily applying horizontal pressure. At the same time, the meshing method of the bevel gears has good transmission efficiency and stability, ensuring the smooth operation of the device during the pressure application process, reducing energy loss and mechanical wear, and being convenient for the maintenance and repair of the device, improving the overall service life and reliability.

[0044] Refer to Figure 3 and Figure 4The column 14 and the hand jack 1 are rotatably connected, and a second limit plate 15 is arranged under each of the multiple hand jacks 1. The rotatable connection design between the column 14 and the hand jack 1 enables the hand jack 1 to be opened on the column 14, so that the device can apply force stably, increasing the use range and convenience of the device. At the same time, the second limit plate 15 arranged under the multiple hand jacks 1 provides stable support and limiting effect for the jack, which facilitates the normal operation of the hand jack 1 and prevents the jack from being unable to open normally, while ensuring the stability and safety of the force application process.

At the same time, this fixed connection also simplifies the structure of the device, reduces possible failure points, and makes the maintenance and maintenance of the device more convenient.

[0046] See also Figure 3 and Figure 4 A support column 16 is provided on one side of the main shaft 9, and the support column 16 is rotatably connected to the main shaft 9 through a cross frame 17. By arranging the support column 16 on one side of the main shaft 9 and realizing rotatable connection with the main shaft 9 through the cross frame 17, the stability and load-bearing capacity of the main shaft 9 are enhanced. The support column 16 provides an additional support point for the main shaft, effectively preventing the shaking or deviation that may occur during the rotation of the main shaft 9. At the same time, it ensures the flexibility of the main shaft 9 during operation and will not be restricted by the additional supporting structure. The combination of stability and flexibility enables the device to maintain stable performance during long-term and high-intensity use, thereby improving the service life and reliability of the device.

[0047] The implementation principle of the utility model is as follows: first, push the cart 12 to the wall that needs to be pressed, then start the motor 11, the motor 11 drives the main shaft 9 to rotate through the gearbox 10, and then transmits the power to the hand jack 1 through the second bevel gear 8 and the first bevel gear 7, so that under the restriction of the second limit plate 15, the hand jack 1 can be gradually opened and pressure can be applied to both sides. When the pressure is insufficient, wood chips can be inserted to increase the pressure. The column 14 provides installation space for multiple hand jacks 1, and the support column 16 ensures that the main shaft 9 can have stable support.
