Description

Technical Field

[0001] The invention relates to the technical field of assembled wall bodies, and in particular to an assembled building support base used in construction projects. Background Art

[0002] Light steel structure houses are residential buildings that use cold-formed thin-walled steel structures as load-bearing frames and light wall materials as enclosure structures. Because of its small component area and small enclosure structure thickness, it can increase the usable area of the building; the structure is light in weight, the amount of soil taken for foundation construction is small, and the damage to land resources is small. The use of ecologically recyclable steel and 90% of plastics that can be recycled and reused makes the application of prefabricated walls more and more extensive. During the wall installation process, the wall is tilted and placed on the support seat. On the one hand, it is to avoid the wall from tipping over and being damaged during the vertical placement of the wall, and on the other hand, it is convenient for large cranes to hoist the wall for easy installation.

[0003] In the utility model with authorization announcement number: CN217232243U, publication date: 2022-08-19, and titled "A prefabricated building support seat for construction projects", it includes a base, a shock absorbing device is provided at the bottom of the base, and a clamping device is provided on the base. The prefabricated building support seat used in construction projects has the advantages of good shock absorption effect and drainage function, which solves the problem that firstly, the support seat is only provided with a vertical shock absorption mechanism, but when an earthquake occurs, the greatest destructive force on the house is the transverse wave, which will cause the house to vibrate horizontally. The device is only provided with shock absorbing support legs, limiting discs, shock absorbing fixed feet, cavities and shock absorbing springs, which can only absorb the energy generated by longitudinal waves, but cannot absorb the energy generated by transverse waves well, and cannot protect the building from being destroyed. Secondly, the support seat has no drainage function, and long-term rain erosion can easily destroy the internal structure of the support seat, thereby causing safety accidents.

[0004] In the prior art including the above-mentioned patent, if the wall is placed horizontally on the ground, although it can save the storage space of the wall, it is necessary to first place the wall from a horizontal state to a vertical state during the hoisting process, and then the hoisting and installation process of the wall is relatively troublesome. If the wall is placed vertically, the stability of the wall during the placement process will be poor, making the wall prone to tipping over. Therefore, after comprehensive consideration of various aspects, it is most appropriate to place the assembled wall at an angle, so a support seat is used to support the assembled wall. In the process of placing the wall on the support seat, the wall must first be placed vertically, and then tilted. Since the wall will collide with the support seat during the tilting process, and the wall is generally heavy, it is easy to cause the wall to deform during the collision. Summary of the invention

Detailed implementation manners

[0039] Please refer to FIGS. 1-10. The present invention provides a prefabricated building support base for construction projects, which includes a base 1.1, two support plates 1.2 disposed on the base 1.1, and a wall 1.3, and further includes: an elastic buffer assembly: which is disposed on the support plate 1.2;

[0040] a clamping assembly: which is disposed on the support plate 1.2 and is driven by the elastic buffer assembly;

[0041] When the wall 1.3 is tilted and abuts against the elastic buffer assembly during the stroke, the clamping assembly is driven to clamp the wall 1.3.

[0042] Specifically, the prefabricated building support base mainly supports the wall 1.3 before the wall 1.3 is hoisted. If the wall 1.3 is horizontally stacked on the ground, although it can save the storage space of the wall 1.3, during the hoisting process, it is necessary to first place the wall 1.3 from the horizontal state to the vertical state, and then the process of hoisting and installing the wall 1.3 is relatively troublesome. If the wall 1.3 is placed vertically, the stability of the wall 1.3 during placement will be poor, making the wall 1.3 prone to tipping over. Therefore, considering various factors, it is most appropriate to place the prefabricated wall 1.3 obliquely. Therefore, a support base is used to support the prefabricated wall 1.3. Therefore, the support base in the prior art includes a base 1.1 and two support plates 1.2 that are radially symmetric with respect to the center line of the support base. The support plates 1.2 are obliquely and fixedly connected to the base 1.1, and the angle between each support plate 1.2 and the base 1.1 is greater than 0 degrees and less than 90 degrees. The angle between each support plate 1.2 and the base 1.1 can be adjusted accordingly according to the on-site installation conditions. By placing each wall 1.3 obliquely on the support frame, it is convenient for the user to hoist the wall 1.3 using a crane during the assembly process of the wall 1.3.

[0043] However, when the wall 1.3 is placed on the support base, first make the wall 1.3 in a vertical state, and then tilt the wall 1.3. Since the wall 1.3 will collide with the support plate 1.2 during the process of the wall 1.3, which will cause the wall 1.3 to deform. Therefore, the innovation point of this application is that during the tilting process of the wall 1.3, the elastic buffer component reduces the acting force generated by the collision between the wall 1.3 and the support plate 1.2 through the elastic buffer component during the abutting process between the wall 1.3 and the support plate 1.2.

[0044] Elastic buffer component: It is arranged on the support plate 1.2. The elastic buffer component has a certain elastic deformation amount. When the elastic buffer component is stressed, it deforms by itself, and then compensates through its own deformation amount, so that the impact force between the wall 1.3 and the support plate 1.2 is reduced. In the prior art, generally, springs, gas springs or other mechanisms that can deform and compensate after being stressed are applicable to this implementation.

[0045] Clamping component: It is arranged on the support plate 1.2. The clamping component is used to clamp the wall 1.3, so as to realize the limit of the wall 1.3. The clamping component is installed on the support plate 1.2 by sliding or rotating or a combination of the two methods.

[0046] When the wall 1.3 is placed on the support base, first make the wall 1.3 in a vertical state, and then tilt the wall 1.3. During the tilting process of the wall 1.3, make the wall 1.3 abut against the upper elastic buffer component of the support plate 1.2, so that the elastic buffer component deforms, and the elastic buffer component drives the clamping component to move on the support plate 1.2 during the deformation process. Then the clamping component clamps the wall 1.3 by sliding or rotating or a combination of the two methods, thereby reducing the acting force between the wall 1.3 and the support plate 1.2 and also driving the clamping component to clamp and limit the wall 1.3.

[0047] In the present invention, when the wall 1.3 is placed on the support frame and the wall 1.3 is transformed from a vertical state to an inclined state, the wall 1.3 abuts against the elastic buffer component, and then the spring buffer component reduces the acting force between the wall 1.3 and the support plate 1.2 during the tilting process, avoiding the collision between the wall 1.3 and the support plate 1.2. Secondly, during the process of the wall 1.3 abutting against the elastic buffer component on the support plate 1.2, the clamping component is driven to clamp the masonry wall 1.3, thereby realizing the limit of the wall 1.3.

[0048] Refer to Figures 1 - 6a As shown, in another embodiment provided by the present invention, the elastic buffer component and the clamping component are connected through a first transmission;

[0049] The elastic buffer assembly includes a transmission column 1.22 slidably connected to the support plate 1.2 and a second spring 1.24 disposed between the transmission column 1.22 and the support plate 1.2.

[0050] Among them, the clamping assembly includes a clamping block 1.23 rotatably connected to the support plate 1.2, and the clamping block 1.23 is connected to the transmission column 1.22 through a first transmission assembly.

[0051] The first transmission assembly includes a third gear 1.230 fixed to the clamping block 1.23 and a rack 1.220 fixedly connected to the transmission column 1.22, and the third gear 1.230 meshes with the rack 1.220.

[0052] Specifically, as Figure 6a shown, two through holes adapted to the transmission column 1.22 are radially symmetrically formed on each support plate 1.2 with its longitudinal center line as the symmetry line. A second spring 1.24 is fixedly connected to the support plate 1.2 at the position of each through hole. A key groove is formed on the circumferential side of each through hole, and a key (not shown in the figure) adapted to the key groove is provided on the circumferential side of each transmission column 1.22, so that each transmission column 1.22 cannot move linearly perpendicular to the support plate 1.2 after being stressed. The second spring 1.24 is sleeved on the transmission column 1.22. One end of the second spring 1.24 is fixedly connected to the support plate 1.2, and the other end of the second spring 1.24 is fixedly connected to the transmission column 1.22. A rack 1.220 is fixedly connected to the bottom end of the transmission column 1.22.

[0053] Clamping blocks 1.23 are rotatably connected to the edge positions of two opposite side walls of the support plate 1.2. Each clamping block 1.23 is L-shaped, and a third gear 1.230 is coaxially and fixedly connected to the rotation shaft position of each clamping block 1.23. The third gears 1.230 are arranged in one-to-one correspondence with the racks 1.220.

[0054] During use, when the wall 1.3 is tilted, the wall 1.3 abuts against the transmission column 1.22 during the tilting process, causing the transmission column 1.22 to compress the second spring 1.24 during movement. And the transmission column 1.22 drives the rack 1.220 to move during movement, thereby causing the rack 1.220 to engage with the third gear 1.230, causing the third gear 1.230 to rotate, and then causing the third gear 1.230 to drive the clamping block 1.23 to rotate on the support plate 1.2. Thus, each clamping block 1.23 clamps the wall 1.3, so that during the tilting process of the wall 1.3, the spring buffer assembly reduces the acting force between the wall 1.3 and the support plate 1.2 during the tilting process, avoiding collision between the wall 1.3 and the support plate 1.2. Secondly, during the process of the wall 1.3 abutting against the elastic buffer assembly on the support plate 1.2, the clamping assembly is driven to clamp the masonry wall 1.3, thereby realizing the limitation of the wall 1.3.

[0055] Referring to Figures 2 - 3 As shown in FIGS. 7 - 10, in another embodiment provided by the present invention, each support plate 1.2 is respectively rotatably connected to the base 1.1; a second transmission assembly is provided between each support plate 1.2 and the base 1.1, and the second transmission assembly is used to drive each support plate 1.2 to switch from an inclined state to a vertical state.

[0056] Among them, the second transmission assembly includes two hydraulic rods 1.4 fixedly connected to the base 1.1 and a transmission unit; the transmission unit includes a plurality of sliders 1.201 slidably connected to the base 1.1, and a first transmission rod 1.20 is hinged between each slider 1.201 and the support plate 1.2, and a second transmission rod 1.41 is hinged between each first transmission rod 1.20 and each hydraulic rod 1.4.

[0057] It further includes: at least two limiting plates 1.10, each limiting block is respectively rotatably connected to the base 1.1; a one - way transmission mechanism is provided between each limiting block and each support plate 1.2, and when the support plate 1.2 switches from an inclined state to a vertical state, the support plate 1.2 drives the correspondingly arranged limiting plate 1.10 to rotate to limit the wall 1.3.

[0058] The one - way transmission mechanism includes a driving gear assembly fixedly connected to the support plate 1.2 and a driven gear assembly fixedly connected to the limiting plate 1.10; the driving gear assembly meshes with the driven gear assembly.

[0059] The driving gear assembly includes a one-way transmission shaft unit fixedly connected to the support plate 1.2 and a second gear 1.21 coaxially arranged with the one-way transmission shaft unit; the driven gear assembly includes a first transmission shaft 1.111 fixedly connected to the limit plate 1.10 and a first gear 1.11 coaxially arranged with the first transmission shaft 1.111; a torsion spring 1.112 is connected between the first gear 1.11 and the first transmission shaft 1.111.

[0060] The one-way transmission shaft unit includes a second transmission shaft 1.212 fixedly connected to the support plate 1.2 and a second sleeve 1.211 fixedly connected to the second gear 1.21, and the second transmission shaft 1.212 is clamped with the second sleeve 1.211; combined Figure 3 and Figure 10 As shown, when the second transmission shaft 1.212 rotates reversely, the second gear 1.21 rotates synchronously with the second transmission shaft 1.212, and when the second transmission shaft 1.212 rotates forward, the second gear 1.21 remains stationary.

[0061] Specifically, as Figure 3 shown, support plates 1.2 are rotatably connected to opposite sides of the base 1.1. The support plates 1.2 are rotatably connected to the base 1.1 through a rotating shaft, enabling each support plate 1.2 to rotate on the base 1.1. Four sliding grooves 1.100 are formed in the support plates 1.2, and a slider 1.201 is correspondingly arranged in each sliding groove 1.100. A first transmission rod 1.20 is hinged between each support plate 1.2 and each slider 1.201. Two hydraulic rods 1.4 are fixedly connected to the base 1.1, and the two hydraulic rods 1.4 are driven by a driving unit. A second transmission rod 1.41 is hinged between each hydraulic rod 1.4 and each first transmission rod 1.20.

[0062] At the position of the rotating shaft on one side of each support plate 1.2, a second transmission shaft 1.212 is coaxially fixedly connected. The second transmission shaft 1.212 is coaxially arranged with the second gear 1.21 through the second sleeve 1.211; as Figure 10 shown, at least three wedge-shaped grooves adapted to the abutting blocks 1.2122 are arranged around the second sleeve 1.211.

[0063] As Figure 9 shown, at least three mounting grooves 1.2121 are arranged in a circular array around the center of the second transmission shaft 1.212. A first spring 1.2123 is fixedly connected in each mounting groove 1.2121, and an abutting block 1.2122 adapted to it is slidably connected in each mounting groove 1.2121. The other end of each first spring 1.2123 is fixedly connected to the corresponding abutting block 1.2122.

[0064] As Figure 7As shown in the figure, the driven gear assembly includes a first transmission shaft 1.111 fixedly connected to the limit plate 1.10 and a first gear 1.11 coaxially arranged with the first transmission shaft 1.111; a torsion spring 1.112 is connected between the first gear 1.11 and the first transmission shaft 1.111.

[0065] A first sleeve 1.110 is coaxially and fixedly connected to the end face of the first gear 1.11. The first sleeve 1.110 is coaxially sleeved on the first transmission shaft 1.111. A torsion spring 1.112 is arranged between the first transmission shaft 1.111 and the first sleeve 1.110. The torsion spring 1.112 is sleeved outside the first rotating shaft and inside the first sleeve 1.110. One leg of the torsion spring 1.112 is fixedly connected to the first transmission shaft 1.111, and the other leg of the torsion spring 1.112 is fixedly connected to the sleeve.

[0066] During the use process, from Figure 1 state moves to Figure 1a state. At this time, the hydraulic rod 1.4 extends, causing the hydraulic rod 1.4 to drive the second transmission rod 1.41 to move, and then causing the second transmission rod 1.41 to drive the first transmission rod 1.20 to move, and then causing each support plate 1.2 to be in a vertical state. During the rotation of each support plate 1.2, the second transmission shaft 1.212 is driven to rotate, and then the abutting block 1.2122 on the second transmission shaft 1.212 abuts against the wedge-shaped groove in the second sleeve 1.211, and then the second transmission shaft 1.212 drives the second gear 1.21 to rotate, causing the second gear 1.21 to mesh with the first gear 1.11. During the process of making the first gear 1.11 rotate, the torsion spring 1.112 stores energy until the torsion spring 1.112 reaches the maximum deformation amount, and then the second gear 1.21 drives the first gear 1.11, so that there is a certain time delay during the rotation of the first gear 1.11 and the second gear 1.21, and then the first gear 1.11 drives the limit plate 1.10 to flip from the horizontal state to the vertical state, and then the abutting block 1.2122 abuts against the wall 1.3. Since there is still an abutting force between the wall 1.3 and the support of the support plate 1.2 at this time, the second spring 1.24 is still in a compressed state, that is, the clamping block 1.23 still clamps the wall 1.3, preventing the wall 1.3 from tipping over when it is in a vertical state.

[0067] After the wall 1.3 is hoisted, at this time the hydraulic rod 1.4 is in a state of restoring to its original length, and then each support plate 1.2 is in reverse rotation, reducing the abutting force of the abutting block 1.2122 against the wedge-shaped groove, and then the torsion spring 1.112 has a certain reset tendency, and under the action of the torsion spring 1.112, the limit plate 1.10 flips to the horizontal state.

[0068] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
