[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0026] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is apparent that these embodiments may also be implemented without these specific details. In other examples, for ease of describing one or more embodiments, known structures and devices are shown in the form of block diagrams.

[0028] In order to solve the problems of the existing elevator foundation scheme that the existing elevator foundation scheme cannot be used in a cyclical manner, has a long dismantling cycle, causes environmental pollution and high costs, etc., the present invention provides a pre-assembled elevator foundation device and an assembly method, wherein the elevator foundation device is provided as a two-part structure that can be assembled and disassembled, namely, a first fixed seat and a second fixed seat, the two fixed seats are assembled through position-corresponding limit parts, and then the two are inserted and positioned together through a connecting rod, which can avoid the dismantling of the traditional elevator foundation device, reduce environmental pollution during crushing and dismantling, and realize multiple cyclical uses of the elevator foundation device, thereby reducing construction costs.

[0029] In order to describe the structure of the prefabricated assembled elevator foundation device and the assembly method of the present invention in detail, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Figures 1 to 5 The overall and partial schematic structures of the prefabricated assembled elevator foundation device according to an embodiment of the present invention are shown from different angles.

[0031] like Figures 1 to 5 As shown together, the prefabricated assembled elevator foundation device of an embodiment of the present invention comprises a first fixed seat 1 and a second fixed seat 2 which can be spliced ​​and disassembled with each other, and at least one connecting rod passing through the first fixed seat 1 and the second fixed seat 2; wherein, a first limiting portion is arranged on the first fixed seat 1, and a second limiting portion matched with the first limiting portion is arranged on the second fixed seat 2, and the splicing of the first fixed base and the second fixed base can be realized by buckling the first limiting portion and the second limiting portion at the corresponding position, and then the first limiting portion and the second limiting portion can be passed through the connecting rod at the same time to complete the connection between the first fixed seat 1 and the second fixed seat 2, which is convenient for the use of the elevator foundation.

[0032] Among them, the first fixed seat 1 and the second fixed seat 2 can form a regular rectangular structure after splicing, that is, a complete elevator foundation device, and then the fixed elevator bracket 3 can be installed thereon, and the temporary elevator can be set on the elevator bracket 3 to complete the construction of this construction elevator. When it needs to be dismantled or transferred, the elevator bracket 3 can be dismantled, and then the connecting rod can be pulled out, and the first fixed seat 1 and the second fixed seat 2 can be separated and hoisted to the next construction location for reuse.

[0033] Specifically, the first limiting portion may include at least one protrusion 15 arranged on the first fixing seat 1, and the second limiting portion may include a groove 25 corresponding to the position of the protrusion 15. The position and number of the grooves 25 correspond to the protrusion 15. During the assembly process, the protrusion 15 can be snapped into the groove 25 at the corresponding position to complete the basic splicing. At this time, a concrete dividing line A will be formed between the first fixing seat 1 and the second fixing seat 2, and then the connecting rod is inserted into the first limiting portion and the second limiting portion to prevent the two from moving in position during use, thereby ensuring the safety and reliability of the construction.

[0034] It should be noted that the first fixing seat 1 and the second fixing seat 2 can be prefabricated with concrete, and the specific size and thickness can be set according to the requirements of the elevator to be built. When the required size of the elevator foundation device is larger, multiple fixing seats can also be set, and the multiple fixing seats are spliced ​​with each other in a snap-fit ​​manner similar to the first limit portion and the second limit portion; in addition, the protrusion 15 can be set to a rectangular structure as shown in the accompanying drawings, or it can be set to a dovetail shape or an "Ω" shape. The shape of the groove 25 is compatible with the protrusion 15. The use of special-shaped structures such as dovetail grooves can prevent the protrusion 15 from detaching from the groove 25, thereby improving the firmness and stability of the combination between the two.

[0035] In addition, in order to improve the structural strength of the precast concrete fixing seat, protective angle irons can be arranged at the edges of the first fixing seat 1 and the second fixing seat 2, that is, a first protective angle steel 13 is arranged at the edge of the first fixing seat 1, and the two fixing surfaces of the first protective angle steel 13 are respectively fitted with the two mutually perpendicular surfaces of the first fixing part; similarly, a second protective angle steel 23 is arranged at the edge of the second fixing seat 2, and the two fixing surfaces of the second protective angle steel 23 are respectively fitted with the two mutually perpendicular surfaces of the second fixing part. The protective angle steels form a frame structure for protecting the concrete fixing seat, thereby improving the service life of repeated use.

[0036] To facilitate the insertion and removal of the connecting rod, in a specific embodiment of the present invention, a first connecting hole 12 distributed in a direction parallel to the surface of the first limiting portion is provided on the protrusion 15, and a second connecting hole 22 penetrating the groove 25 is provided on the second fixing seat 2; when the protrusion 15 is limited in the corresponding position groove 25, the first connecting hole 12 and the second connecting hole 22 are connected to each other and are located on a straight line. At this time, the connecting rod is passed through the first connecting hole 12 and the second connecting hole 22 to complete the insertion and positioning of the first fixing seat 1 and the second fixing seat 2.

[0037] It can be seen that in order to improve the stability of the connection and prevent the fixed seat (including the first fixed seat 1 and the second fixed seat 2) from rotating along the axial direction of the connecting rod, multiple connecting rods can be set. The multiple connecting rods can be set parallel to each other or distributed perpendicular to each other, so as to connect the first fixed seat 1 and the second fixed seat 2 at multiple angles.

[0038] It should be noted that, during the disassembly and assembly process of the prefabricated assembled elevator infrastructure device, in order to facilitate the transfer of the first fixed seat 1 and the second fixed seat 2, pre-embedded lifting rings can be further arranged on the first fixed seat 1 and the second fixed seat 2. In other words, the first pre-embedded lifting ring 11 is accommodated and arranged in the first fixed seat 1, and the second pre-embedded lifting ring 21 is accommodated and arranged in the second fixed seat 2; wherein, the first pre-embedded lifting ring 11 and the second pre-embedded lifting ring 21 are used to be buckled with an external lifting device to lift the first fixed seat 1 and the second fixed seat 2, and the lifting of the elevator infrastructure device can be completed by a small crane, which is simple to operate and low in cost.

[0039] Among them, during the setting process of the first embedded lifting ring 11 and the second embedded lifting ring 21, when the concrete of the first fixing seat 1 and the second fixing seat 2 is poured and formed, a reserved groove can be formed at a preset position through a template, and then the embedded lifting ring is placed in the reserved groove and welded to the structural steel bars inside the concrete. As a specific example, the embedded lifting ring can be reserved with a PVC sleeve, and the embedded lifting ring is embedded in a slotted PVC pipe and welded to the steel bars in the corresponding fixing seat. In addition, the embedded lifting ring embedded in the PVC pipe can be treated with rust prevention, and the upper mouth of the PVC can be sealed with cotton felt when pouring concrete to prevent concrete from falling into the PVC pipe and contaminating the embedded lifting ring.

[0040] Corresponding to the above-mentioned pre-assembled elevator foundation device, the present invention also provides an assembly method for the pre-assembled elevator foundation device, which is used to assemble the above-mentioned pre-assembled elevator foundation device. The assembly method includes: snapping the first limit part of the first fixing seat with the second limit part of the second fixing seat at the corresponding position, and splicing the first fixing seat and the second fixing seat into a rectangle; passing the connecting rod through the first fixing seat and the second fixing seat, and positioning the two ends of the connecting rod respectively; the disassembly process is the opposite, first pulling the connecting rod out of the first fixing seat and the second fixing seat, and then separating the first fixing seat and the second fixing seat.

[0041] Among them, in order to facilitate the installation and disassembly of the connecting rod, pin holes can be set at both ends of the connecting rod. After the connecting rod is inserted into the first fixing seat and the second fixing seat, a pin or other structure is inserted into the pin hole to lock the position of the connecting rod to prevent it from shifting or falling off.

[0042] It should be noted that, for the embodiments of the assembly method of the above-mentioned prefabricated assembled elevator foundation device, reference may be made to the description in the embodiments of the prefabricated assembled elevator foundation device, which will not be described in detail here.

[0043] According to the above-mentioned prefabricated assembled elevator basic device and assembly method, the elevator basic device is configured as a plurality of assembleable and disassembled structures, and then mutually adaptable limiting parts are provided on each structure, and the mutual limiting between the limiting parts is used to realize the assembly between the various fixing seats, and finally the plurality of fixing seats are inserted and positioned together through connecting rods, which can not only avoid the environmental pollution and high cost caused by the dismantling of the traditional elevator basic device, but also can be repeatedly used, thereby reducing the construction cost of temporary elevators.

[0044] As described above, the pre-assembled elevator foundation device and the assembly method according to the present invention are described by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various improvements can be made to the pre-assembled elevator foundation device and the assembly method proposed by the present invention without departing from the content of the present invention.
