Description

Technical Field

[0001] This invention relates to the field of elevator shaft technology, and specifically to a truss-type bolted steel shaft. Background Technology

[0002] Traditional elevator installations in older residential communities often employ a full steel frame structure for the shaft. This type of structure relies heavily on on-site welding to connect and fix the components. On one hand, on-site welding is highly susceptible to environmental factors. Inclement weather such as rain, snow, high temperatures, or low temperatures can disrupt welding, delaying the construction period. Furthermore, temperature fluctuations can affect weld quality, leading to insufficient weld strength and cracking, requiring significant manpower and resources for repair welding and testing, increasing project costs and safety risks. On the other hand, the components of the full steel frame structure often need to be cut, processed, and adjusted on-site. Since construction sites in older residential communities are typically cramped, large processing equipment is difficult to access, and component processing precision is hard to guarantee. Moreover, the noise and dust pollution generated by on-site work can severely disrupt the daily lives of nearby residents, causing neighborhood disputes and hindering the smooth progress of construction.

[0003] Traditional all-steel frame elevator shafts have poor adaptability. Regarding curtain wall types, the connection between traditional shaft structures and curtain walls is relatively fixed, only compatible with specific types of curtain walls. If residents or construction companies need to change the curtain wall material (e.g., from ordinary glass curtain walls to aluminum-magnesium-manganese panel curtain walls or ALC panel curtain walls), large-scale modifications to the shaft structure are required, including re-welding connectors and adjusting frame dimensions. This not only increases modification costs but may also compromise the original structural stability of the shaft. In terms of elevator brand compatibility, different elevator brands have different installation dimensions and guide rail fixing requirements. Traditional shafts often have fixed designs for guide rail supports and car running space, which cannot be flexibly adjusted. This severely limits the choice of elevator brands for construction companies, making subsequent modifications to the shaft structure extremely difficult if a new elevator brand needs to be selected.

[0004] Furthermore, the terrain and working conditions of older residential areas are complex and diverse, with some areas experiencing uneven ground and narrow construction spaces (such as insufficient building spacing and numerous surrounding obstacles). Traditional all-steel frame shafts, due to the large size and weight of their components and the need for extensive on-site assembly, face challenges in confined spaces where large hoisting equipment cannot be deployed, leading to difficulties in component transportation and installation and low construction efficiency. Conversely, even in more open construction sites, traditional shafts cannot achieve pre-assembly and overall hoisting of components, still requiring piece-by-piece on-site assembly, failing to fully utilize site advantages to improve construction speed.

[0005] In summary, existing traditional all-steel frame elevator shafts have significant shortcomings in terms of construction environment adaptability, flexibility of adaptation, and quality stability. There is an urgent need for a new type of elevator shaft structure to solve many pain points in the process of adding elevators to old residential communities and meet the installation requirements of high efficiency, high quality, and high adaptability. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned problems and provide a truss-type bolted steel structure shaft. To achieve the above objective, this invention adopts the following technical solution:

[0007] A truss-type bolted steel shaft includes a shaft structure and a corridor structure. The shaft structure is fixed to the ground, one end of the corridor structure is fixed to the back of the shaft structure, and the other end of the corridor structure is fixed to a concrete wall.

[0008] The shaft structure includes several shaft modules connected vertically. Each shaft module includes four shaft steel columns and several shaft steel beams. The four shaft steel columns are arranged in a rectangular shape, and the shaft steel beams are set between adjacent shaft steel columns. The shaft steel beams on the same floor are located on the same plane. The shaft steel beams are located on the front and side of the corridor structure. The shaft steel columns are inclined with diagonal braces between adjacent shaft steel columns. The diagonal braces are located between two upper and lower shaft steel beams. The diagonal braces are located on the front and side of the corridor structure.

[0009] The shaft steel beam is equipped with several keel connectors, which are connected to the shaft curtain wall.

[0010] As an improvement, the shaft structure also includes a top structure and steel column feet. The top structure is set on the top of the top shaft module, and the steel column feet are set on the bottom of the bottom shaft module. A reserved steel plate is provided on the ground, and the steel column feet are fixed on the reserved steel plate.

[0011] The top structure includes a top steel beam, which is set on top of adjacent shaft steel columns. The top steel beam is located on the four sides of the shaft structure, and a middle steel beam is provided between the middle parts of the top steel beams on the left and right sides.

[0012] As an improvement, the shaft steel column and the steel column base are H-shaped steel columns, and the connection between the upper and lower shaft steel columns and the connection between the shaft steel column and the steel column base are provided with segmented plates for fixation.

[0013] The shaft steel beams and shaft steel columns are fixed by corner bracing plates or connecting plates.

[0014] As an improvement, the top steel beam and the middle steel beam are H-shaped steel beams, and two strong shaft plates are provided at the junction of the top steel beam and the shaft steel column and the junction of the middle steel beam and the top steel beam for fixing. The two strong shaft plates are located on both sides of the H-shaped steel beam.

[0015] As an improvement, the bottom of the intermediate steel beam is provided with several lifting lugs.

[0016] As an improvement, the corridor bridge structure includes a shaft portal beam and two corridor bridge steel beams. The shaft portal beam is set between the shaft steel columns, and the corridor bridge steel beam is set between the concrete wall and the shaft steel columns. Several corridor bridge crossbeams are provided between the two corridor bridge steel beams, and two shaft portal columns are symmetrically arranged between two adjacent shaft portal beams.

[0017] As an improvement, embedded parts are provided at the junction of the steel beam of the corridor bridge and the concrete wall, a strong axis plate is provided at the junction of the steel beam of the corridor bridge and the steel column of the shaft, a connecting plate is provided at the junction of the shaft portal beam and the shaft steel column, and a portal column connector is provided between the shaft portal beam and the shaft portal column.

[0018] As an improvement, the segmented plates, corner bracing plates, connecting plates, reinforcing shaft plates, and gatepost connectors are fixed to the shaft structure or corridor structure with high-strength bolts.

[0019] The advantages of this invention are:

[0020] 1. The present invention has a stable structure and strong adaptability: the truss structure and high-strength bolt connection system enhance the overall rigidity and have excellent anti-lateral displacement performance; it is compatible with various brands of elevators and various curtain wall forms such as glass and aluminum-magnesium-manganese panels, meeting the needs of different architectural styles.

[0021] 2. This invention is prefabricated in the factory, and the quality is controllable: the shaft module and the corridor structure can be produced in the factory in a standardized manner, which is not affected by the site environment and the dimensional accuracy is easy to control; the steel structure paint has a long warranty period, reducing the later maintenance cost.

[0022] 3. This invention is easy to install and highly efficient: it adopts a fully bolted connection (except for the steel column base), which can be operated by elevator installers; when space is limited, it can be hoisted by a self-climbing crane, and when space is sufficient, it can be pre-assembled on the ground and then quickly installed. The integrated design of the corridor bridge supports overall hoisting, which significantly shortens the construction cycle.

[0023] 4. The curtain wall of this invention is easy to replace: the curtain wall and the shaft steel beam are fixed by bolts through keel connectors, and the glass and other curtain wall components are installed using slot kits. If a single component is damaged later, it can be replaced individually, resulting in low maintenance costs. Attached Figure Description

[0045] The present invention will now be described in detail and specifically through specific embodiments to enable a better understanding of the invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0046] Example 1

[0047] This embodiment discloses a truss-type bolted steel shaft.

[0048] like Figures 1 to 5 As shown, this embodiment includes a shaft structure 1 and a corridor structure 2, which together form the passage for elevator operation and personnel access. The specific structure is as follows:

[0049] (I) Shaft Structure 1

[0050] The shaft structure 1 provides vertical space and load-bearing support for elevator operation. It is fixed to the ground and adopts a modular design, including several shaft modules 11, a top structure 12, and steel column bases 13.

[0051] Shaft module 11: Several shaft modules 11 are connected vertically to form the main shaft body. Each shaft module 11 includes four shaft steel columns 111 and several shaft steel beams 112.

[0052] The shaft steel columns 111 are connected to the steel beams: Four shaft steel columns 111 are arranged in a rectangle, serving as the vertical load-bearing framework of the module; shaft steel beams 112 are set between adjacent shaft steel columns 111, and the shaft steel beams 112 on the same floor are located on the same plane and distributed on the front and sides of the corridor structure 2 (forming a three-sided enclosed frame). The shaft steel beams 112 are fixed to the shaft steel columns 111 by corner bracing plates 14 or connecting plates 15 to ensure the stable transmission of horizontal forces.

[0053] Shaft diagonal bracing 113: Shaft diagonal bracing 113 is inclined between adjacent shaft steel columns 111. Shaft diagonal bracing 113 is located between the upper and lower shaft steel beams 112 and is distributed on the front and side of the corridor structure 2. Together with the steel beams and steel columns, it forms a truss structure, which significantly improves the overall rigidity and anti-lateral displacement ability of the shaft module 11, and is especially suitable for high-rise elevator installation scenarios.

[0054] Keel connector 114: Several keel connectors 114 are provided on the shaft steel beam 112 for connecting the keel structure of the shaft curtain wall. They are compatible with various curtain wall forms such as glass, aluminum-magnesium-manganese panels, ALC panels, and aluminum panels. Through the standardized design of the connectors, the curtain wall can be installed and replaced quickly.

[0055] Top structure 12 and steel column base 13:

[0056] Top structure 12: Located on top of the top shaft module 11, including top steel beam 121 and intermediate steel beam 122. Top steel beam 121 is located on top of adjacent shaft steel columns 111, distributed on the four sides (front, back, and two sides) of shaft structure 1; intermediate steel beam 122 is provided between the middle of the top steel beams 121 on the left and right sides to enhance the integrity of top structure 12.

[0057] Both the top steel beam 121 and the middle steel beam 122 are H-shaped steel beams. Two reinforcing plates 123 (located on both sides of the H-shaped steel beams) are installed at their junctions and at their junctions with the shaft steel columns 111 to ensure stable top load-bearing capacity. These plates can be used to install components such as top insulation and drainage gutters. Several lifting lugs 124 are provided at the bottom of the middle steel beam 122 to facilitate module hoisting.

[0058] Steel column base 13: Set at the bottom of the bottom shaft module 11, with a reserved steel plate on the ground. The steel column base 13 is fixed to the reserved steel plate (welding can be used for fixing) to transfer the shaft load to the ground foundation.

[0059] Connection nodes: Both the shaft steel column 111 and the steel column base 13 are H-shaped steel columns. The connection between the upper and lower shaft steel columns 111 and the connection between the shaft steel column 111 and the steel column base 13 are fixed with segment plates 131. The connection nodes between the top steel beam 121, the middle steel beam 122 and the steel column are all fixed with high-strength bolts to ensure connection strength and ease of installation, and to avoid on-site welding.

[0060] (II) Corridor Bridge Structure 2

[0061] The corridor structure 2 is used to connect the shaft to the main building. One end is fixed to the back of the shaft structure 1, and the other end is fixed to the concrete wall 3. It includes the shaft door beam 21, two corridor steel beams 22, and shaft door column 24.

[0062] Main frame: Shaft door beams 21 are set between shaft steel columns 111 (forming shaft entrance frame), and corridor bridge steel beams 22 are set between concrete wall 3 and shaft steel columns 111. Two corridor bridge steel beams 22 are arranged in parallel, with several corridor bridge crossbeams 23 between them to form the horizontal load-bearing structure of the corridor bridge; two shaft door columns 24 are symmetrically set between two adjacent shaft door beams 21 to enhance the stability of the entrance frame.

[0063] Connection nodes: Embedded parts 25 are used for fixing at the junction of the corridor bridge steel beam 22 and the concrete wall 3, and a reinforcing plate 123 is used for fixing at the junction of the steel beam 22 and the shaft steel column 111; a connecting plate 15 is used for fixing at the junction of the shaft portal beam 21 and the shaft steel column 111, and a portal column connector 26 is used for fixing between the portal beam 21 and the shaft portal column 24. All node components, including the segment plates 131, corner bracing plates 14, connecting plates 15, reinforcing plates 123, and portal column connectors 26, are fixed to the shaft structure 1 or corridor bridge structure 2 using high-strength bolts, achieving welding-free installation.

[0064] Overall installation plan

[0065] First, weld the H-shaped steel column base 13 to the pre-reserved steel plate on the ground to complete the fixation of the bottom of the shaft structure 1;

[0066] If the construction site has limited space, a self-climbing crane is used as the hoisting equipment to hoist the components of the shaft module 11, such as the shaft steel column 111 and shaft steel beam 112, to the preset installation position. The components are then fixed to the segment plate 131, corner support plate 14, connecting plate 15, and other connecting parts with high-strength bolts, thereby achieving the layer-by-layer assembly of the shaft module 11.

[0067] If there is sufficient space at the construction site, several shaft modules 11 can be pre-assembled on the ground to form a larger assembly unit. Then, a small crane can be used to lift the pre-assembled assembly unit to the installation position and fix it quickly with high-strength bolts to shorten the on-site installation time.

[0068] The corridor bridge structure 2 adopts an integrated design. After the overall prefabrication is completed in the factory, it is transported to the construction site. The corridor bridge structure 2 is hoisted as a whole to the preset position between the shaft structure 1 and the concrete wall 3 using hoisting equipment. It is then fixed to the shaft steel column 111 and the concrete wall 3 through connectors such as embedded parts 25, strong shaft plate 123, and connecting plate 15.

[0069] The H-beams (including shaft steel columns 111, shaft steel beams 112, top steel beams 121, etc.) have pre-set slots. After the shaft structure 1 and the corridor structure 2 are installed, the shaft edging is installed by aligning the pre-set slots. For the installation of the curtain wall glass, the custom glass slot kit is fixed to the pre-drilled beam (shaft steel beam 112 or corridor beam 23) with bolts. Then the glass is hoisted into the custom slot, so that the glass and the slot kit are interlocked. At the same time, a certain space is reserved between the glass and the components to facilitate the replacement of individual glass pieces later.

[0070] Example 2

[0071] like Figure 6 , Figure 7 As shown, this embodiment discloses a glass curtain wall scheme 42 for a truss-type bolted steel structure shaft.

[0072] After the shaft structure 1 is installed, the curtain wall edging fasteners are pre-installed on the shaft steel column 111 to ensure that the fasteners are accurately positioned and firmly fixed.

[0073] Install the curtain wall shaft edging 41 onto the pre-installed shaft fasteners, adjust the edging position to ensure that the edging fits tightly against the shaft steel column 111, and further fix it with bolts;

[0074] The glass and glass clips are installed on the shaft steel beam 112 in the design sequence. The glass clips correspond to the openings on the shaft steel beam 112. The glass clips are fixed with bolts to achieve the positioning and fixing of the glass.

[0075] Install keels on the top steel beam 121 and the middle steel beam 122 of the shaft top structure 12. After the keels are installed, lay a heat insulation layer on the inside of the keels to ensure that the heat insulation layer covers the entire shaft and is securely fixed.

[0076] Install glass edge trim strips, attach the edge trim strips to the connection between the glass edge and the shaft structure 1, and fix them with connectors to achieve edge sealing and decoration of the glass curtain wall 42;

[0077] Insulation material is laid on top of the insulation layer at the top of the shaft. After the insulation material is laid, drainage gutter 43 is installed at the top edge of the shaft to ensure that the slope of the drainage gutter 43 is reasonable and the drainage is unobstructed.

[0078] Finally, install the corridor bridge edging 44, which is installed on the edge of the corridor bridge structure 2 and fixed with bolts to complete the installation of the entire glass curtain wall 42.

[0079] Example 3

[0080] This embodiment discloses a second glass curtain wall scheme for a truss-type bolted steel shaft.

[0081] After the shaft structure 1 and the corridor structure 2 are installed, the glass and glass clips are installed on the shaft steel beam 112 and the corridor crossbeam 23 in sequence according to the design position. The glass clips are fixed to the openings on the crossbeam with bolts to ensure that the glass is installed flat and firmly.

[0082] Install keels on the top steel beam 121 and the middle steel beam 122 at the top of the shaft. After the keels are installed, lay a heat insulation layer on the inside of the keels to ensure the integrity and fixation of the heat insulation layer.

[0083] Install edge trim strips for the curtain wall glass. Install the edge trim strips at the connection between the glass and the shaft structure 1 and the corridor structure 2, and fix them with connectors to achieve edge treatment of the glass curtain wall.

[0084] Insulation material is laid on top of the insulation layer at the top of the shaft. After the insulation material is laid, drainage gutters are installed at the top edge of the shaft, ensuring that the drainage gutters are installed in the correct position and that the drainage function is normal.

[0085] Finally, install the edging of the corridor bridge. Install the edging of the corridor bridge on the outer edge of the corridor bridge structure 2 and fix it with bolts to complete the overall installation of the glass curtain wall.

[0086] Example 4

[0087] This embodiment discloses an aluminum-magnesium-manganese panel curtain wall scheme for a truss-type bolted steel structure shaft.

[0088] After the shaft structure 1 is installed, the main keel is installed at the fixed position of the shaft steel beam 112. The main keel is connected to the shaft steel beam 112 by bolts to ensure that the verticality and horizontality of the main keel meet the design requirements.

[0089] The well casing edge is fixed to the installed main keel with self-tapping screws. The position of the edge needs to be adjusted during installation to ensure that the edge fits tightly with the main keel and the joint is flat.

[0090] The aluminum-magnesium-manganese panels are aligned and fixed to the main keel in the order of the design using self-tapping screws. When installing the aluminum-magnesium-manganese panels, it is necessary to ensure that the overlap length between the panels meets the specifications and that the surface of the panels is flat without warping or deformation.

[0091] Drainage gutters are installed on the top steel beam 121 and the middle steel beam 122 at the top of the shaft. The drainage gutters are fixed to the steel beams through brackets to ensure that the slope of the gutters is reasonable and the joints are well sealed to prevent water leakage.

[0092] Finally, install the edging of the corridor bridge. Fix the edging of the corridor bridge to the edge of the corridor bridge structure 2 with self-tapping screws or bolts to complete the installation of the aluminum-magnesium-manganese panel curtain wall.

[0093] Example 5

[0094] This embodiment discloses an ALC panel curtain wall scheme for a truss-type bolted steel structure shaft.

[0095] After the shaft structure 1 is installed, angle irons are fixed between the bottom shaft steel beams 112. The angle irons are connected to the shaft steel beams 112 by bolts to serve as the bottom support of the ALC plate.

[0096] Use hook bolts to connect the ALC plate to the shaft steel structure (shaft steel column 111 or shaft steel beam 112). The hook bolts pass through the pre-drilled holes in the ALC plate and are fixed to the shaft steel structure to ensure that the ALC plate is installed firmly.

[0097] ALC plates are installed layer by layer. After every 6 ALC plates are installed, an angle iron is installed in the middle of the ALC plates in that layer. The angle iron is fixed to the shaft steel structure with bolts to reinforce the ALC plates laterally and prevent them from deforming or falling off.

[0098] After all ALC panels are installed, the outer surface of the ALC panels is treated. First, exterior wall putty is applied to ensure that the putty layer is smooth and free of cracks. After the putty dries, it is sanded.

[0099] Apply stone paint evenly to the sanded and smoothed putty layer. The thickness of the stone paint should meet the design requirements to ensure the appearance and durability.

[0100] Finally, a drainage gutter is installed at the top of the shaft, and the corridor bridge edging is installed. The drainage gutter is fixed to the top steel beam 121 through a bracket, and the corridor bridge edging is fixed to the edge of the corridor bridge structure 2 with bolts, thus completing the installation of the ALC panel curtain wall.

[0101] Example 6

[0102] This embodiment discloses an aluminum panel curtain wall scheme for a truss-type bolted steel structure shaft.

[0103] After the shaft structure 1 is installed, the main keel is installed at the fixed position of the shaft steel beam 112. The main keel is connected to the shaft steel beam 112 by bolts. The position of the main keel is adjusted to ensure that the verticality and spacing of the main keel meet the design requirements.

[0104] The secondary keel is inserted into the main keel that has been drilled, and the connection between the secondary keel and the main keel is fixed with bolts to form a complete curtain wall keel frame.

[0105] Before installing the aluminum plate, check its appearance quality. After confirming that the aluminum plate is free of scratches, deformation, color difference, etc., fix the aluminum plate to the secondary keel with self-tapping screws. When installing the aluminum plate, ensure that the plate is flat and the gap between adjacent aluminum plates is uniform.

[0106] After all aluminum panels are installed, check the flatness of the aluminum panel surface to ensure that the flatness error of the aluminum panel is less than 2mm. If there is any error, adjust it in time.

[0107] Drainage gutters are installed on the top steel beam 121 and the middle steel beam 122 at the top of the shaft. The drainage gutters are fixed by brackets to ensure that the drainage slope and the joint sealing of the gutters meet the requirements.

[0108] Install the edging of the corridor bridge and fix the edging of the corridor bridge to the edge of the corridor bridge structure 2 with bolts;

[0109] Finally, the gaps between the aluminum panels are treated. First, foam strips are filled into the gaps, ensuring that the foam strips fill the gaps completely and do not protrude from the surface of the aluminum panels. Then, black sealant is applied to the outside of the foam strips. The sealant should be applied evenly and continuously, without bubbles or gaps, to complete the installation of the aluminum panel curtain wall.

[0110] Through the above-mentioned overall installation scheme and various curtain wall adaptation embodiments, the truss-type bolted steel structure shaft of the present invention can achieve factory prefabrication and on-site welding-free rapid installation, adapt to various curtain wall forms, and facilitate subsequent maintenance. It can effectively solve many technical pain points in the process of adding elevators to old residential areas and meet the requirements of efficient and high-quality installation.
