Description

Technical Field

[0001] The utility model relates to the technical field of elevator construction and installation, in particular to an elevator shaft structure that can be assembled in an integral manner. Background Art

[0002] As people's living standards continue to improve, installing elevators in old communities is becoming more and more popular. In the installation of elevators in old communities, the main structures of the elevator shaft are steel structures and concrete structures, and the concrete structures are almost all cast-in-place. Cast-in-place concrete structures have a long construction period and require a large number of scaffolding. Materials are stacked on site, and long-term construction work occupies space for a long time. The site environment is dirty and messy, which affects the daily life of residents. Therefore, it is necessary to propose an elevator shaft structure that can be assembled in an integral manner to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to overcome the above shortcomings and deficiencies of the prior art and provide an elevator shaft structure that can be assembled in an integral manner.

[0004] An elevator shaft structure that can be assembled as a whole, including multiple standard sections, which are spliced ​​in sequence from bottom to top. The standard section includes four columns and a lightweight concrete wall arranged between two adjacent columns. The lightweight concrete wall is composed of an insulation board, a steel mesh, a support block and a concrete layer. The steel mesh is arranged on both sides of the insulation board, the support block connects the insulation board and the steel mesh, and the concrete layer is filled between the insulation board and the steel mesh and the steel mesh; multiple shock-absorbing blocks and micro-expansive cement mortar layers are arranged between two adjacent standard sections, and the height of the micro-expansive cement mortar layer is not less than the height of the shock-absorbing block.

[0005] The main components of the elevator shaft that can be assembled as a whole according to the utility model are prefabricated in the factory, and their appearance is the same as that of integrally cast concrete. They can be hoisted on site, and scaffolding installation is eliminated. The installation is efficient and fast, the site is clean and tidy, and the impact on residents is reduced. The weight of the elevator shaft can also be reduced, saving material costs. A plurality of shock-absorbing blocks are arranged between the standard sections to achieve shock absorption, and a certain gap must be reserved for the docking of two standard parts. The provision of the shock-absorbing blocks also serves as a limiter, which can avoid the disadvantage of hard collision when two upper and lower adjacent standard sections are docked.

[0006] In one embodiment, a corrugated pipe is provided on the column, ribbed steel bars are provided inside the corrugated pipe, and a grouting connection portion is provided between the ribbed steel bars and the corrugated pipe.

[0007] When the elevator shaft is prefabricated in the factory, the connecting components are embedded at the required positions to connect the upper and lower adjacent standard sections of the elevator shaft, which are connected through the ribbed steel bars in the columns. When the elevator shaft is supported by the formwork, the corrugated pipe is embedded in the steel cage of the column, and then the two ends of the corrugated pipe are blocked to prevent concrete from flowing in; because the corrugated pipe has a spiral convex texture, it can increase the bonding strength between the corrugated pipe and the concrete. Among them, multiple corrugated pipes are arranged on each column, located at the four corners of the shaft.

[0008] In one embodiment, the bellows is a metal bellows.

[0009] In one embodiment, the bellows extends vertically to the upper and lower ends of the column.

[0011] In one embodiment, a cross beam is connected between two adjacent columns, and the lightweight concrete wall is disposed between the two cross beams.

[0012] When the lightweight concrete wall is used to set up the steel bars of the beams and columns, the insulation board and steel mesh are buried between the beams and columns. The insulation board is in the middle, and the steel mesh is on both sides. The support block is used to support the steel mesh. There is a certain gap between the steel mesh, the insulation board and the outer mold to facilitate the flow of concrete during pouring. When pouring concrete, it is covered to achieve the same appearance as the integral pouring of concrete. The lightweight concrete wall is used to fill the space between the columns and beams to reduce weight and save material costs.

[0013] In one embodiment, the support block and the insulation board are fixed by adsorption.

[0014] In one embodiment, the cross-section of the column is L-shaped.

[0015] The beneficial effects of the elevator shaft structure that can be assembled as a whole according to the utility model are: the main components are prefabricated in the factory, and their appearance is no different from that of integrally cast concrete. They can be hoisted on site, eliminating the need for scaffolding installation, and are efficient and fast. The site is clean and tidy, reducing the impact on residents, and can reduce the weight of the elevator shaft and save material costs. A plurality of shock-absorbing blocks are arranged between standard sections to achieve shock absorption, and a certain gap must be reserved for the docking of two standard parts. The provision of the shock-absorbing blocks also serves as a limiter, which can avoid the disadvantage of hard collision when two upper and lower adjacent standard sections are docked.

[0031] Example

[0032] See also Figure 1 The utility model provides an elevator shaft structure (hereinafter referred to as elevator shaft) 100 that can be assembled in an integral manner, including a standard section 1. A plurality of standard sections 1 are spliced ​​in sequence from bottom to top. The standard section 1 includes four columns 11. A lightweight concrete wall 12 is provided between each two adjacent columns. Preferably, the cross-sectional shape of the column 11 is L-shaped, and may also be square or rectangular, or other shapes.

[0033] See also Figure 2 and Figure 3 The lightweight concrete wall 12 is composed of an insulation board 121, a steel mesh 122, a support block 123 and a concrete layer 124. The steel mesh 122 is arranged on both sides of the insulation board 121. The support block 123 connects the insulation board 121 and the steel mesh 122. The concrete layer 124 is filled between the insulation board 121 and the steel mesh 122 and covers the entire steel mesh 122. The support block 123 and the insulation board 121 are fixed by adsorption, and can also be fixed by pasting or hot melting.

[0034] See also Figure 7 A plurality of shock absorbing blocks 2 and a micro-expansion cement mortar layer 3 are arranged between two adjacent standard sections 1, and the height of the micro-expansion cement mortar layer 3 is not less than the height of the shock absorbing block 2. Preferably, the shock absorbing block 2 is an elastic block.

[0035] The main components of the elevator shaft 100 that can be assembled in an integral manner according to the utility model are prefabricated in the factory, and their appearance is the same as that of integrally cast concrete. They can be hoisted on site without the need for scaffolding installation, which is efficient and fast, keeps the site clean and tidy, reduces the impact on residents, and can reduce the weight of the elevator shaft 100 and save material costs. A plurality of shock-absorbing blocks 2 are arranged between the standard sections 1 to achieve shock absorption, and a certain gap must be reserved for the docking of two standard parts 1. The arrangement of the shock-absorbing blocks 1 also serves as a limiter, which can avoid the disadvantage of a hard collision between two upper and lower adjacent standard sections 1 when docking.

[0036] More specifically, see Figures 4 to 7The column 11 is provided with a corrugated pipe 13, a ribbed steel bar 14 is provided in the corrugated pipe 13, and a grouting connection portion 15 is provided between the ribbed steel bar 14 and the corrugated pipe 13. The corrugated pipe 13 is preferably a metal corrugated pipe. More preferably, the corrugated pipe 13 extends to the upper and lower ends of the column 13 along the vertical direction.

[0037] When the standard section 1 of the elevator shaft 100 is prefabricated in the factory, ribbed steel bars 14 are pre-buried at the required position for connecting the upper and lower adjacent standard sections 1 of the elevator shaft 100. When the standard section 1 is supported, the corrugated pipe 13 is buried in the steel cage of the column 11, and then the two ends of the corrugated pipe 13 are blocked to prevent concrete from flowing in; because the corrugated pipe 13 has a spiral convex texture, the bonding force between the corrugated pipe 13 and the concrete can be increased. There are multiple corrugated pipes 13, and each column 11 is arranged with multiple corrugated pipes 13.

[0038] More specifically, see Figure 6 When two ribbed steel bars 14 need to be connected, threaded portions 141 are provided at both ends of the ribbed steel bars 14, and a steel bar connecting sleeve 16 is provided between the two ribbed steel bars 141 connected up and down, and the steel bar connecting sleeve 16 is set in the threaded portion 141 for connection.

[0039] In another implementation of this embodiment, see Figure 8 , a crossbeam 17 is also connected between two adjacent columns 11, and a lightweight concrete wall 12 is arranged between the two crossbeams 17 and between two adjacent columns 11. Among them, when the lightweight concrete wall 12 is erected with the steel bars of the crossbeam 17 and the column 11, the insulation board 121 and the steel mesh 122 are buried between the crossbeam 17 and the column 11, the insulation board 121 is in the middle, and the steel mesh 122 is on both sides. The function of the support block 123 is to support the steel mesh 122. There is a certain gap between the steel mesh 122 and the insulation board 121 and the outer mold, which is convenient for the concrete to flow down during pouring. When pouring concrete, it is covered to obtain a standard section 1, and the appearance of the standard section 1 is the same as that of the integrally poured concrete. The column 11 and the crossbeam 17 are filled with a lightweight concrete wall 12, and the weight of the insulation board 121 is much less than the weight of the concrete, which reduces the weight and saves material costs.

[0040] During the installation of the utility model, when the standard section 1 of the elevator shaft 100 is prefabricated and hoisted on site, the hole of the corrugated pipe 13 embedded in each column 11 in the upper standard section 1 corresponds to the ribbed steel bar 14 reserved under the lower standard section 1, and the standard section 1 is aligned and lowered; the reserved length of the ribbed steel bar 14 exceeds the height of the shaft of the standard section 1, which is convenient for docking operation. Since the length of each ribbed steel bar 14 is limited, when another ribbed steel bar 14 needs to be connected, the steel bar connection sleeve 16 is screwed into place, and then the upper ribbed steel bar 14 is connected to the steel bar connection sleeve 16 to complete the connection. After all the ribbed steel bars 14 are connected, grouting material is poured into each corrugated pipe 13, so that the ribbed steel bars 14 and the corrugated pipe 13 are tightly connected through the grouting connection part 15, so that the ribbed steel bars 14 and the column 11 form a whole, effectively connecting the upper and lower standard sections 1.

[0041] In one of the installation methods, see Figure 7 , place several shock-absorbing blocks 2 on the upper end surface of the standard section 1 below, and then pour a layer of micro-expansive cement mortar layer 3. The thickness of the micro-expansive cement mortar layer 3 is slightly higher than the shock-absorbing block 2. Align the upper standard section 1 and put it down, then connect the ribbed steel bars 14, and install it upwards layer by layer.

[0042] When the roof (not shown) is installed, the ribbed steel bar 14 is lower than the upper surface of the roof, and the grouting material is poured into the corrugated pipe 13 to the upper surface of the flat roof, and the installation of the shaft part is completed. After the strength of the cement mortar reaches the standard, the upper and lower standard sections 1 are effectively connected to form a whole.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
