Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to a shaft construction device, a building construction machine and a construction method thereof. Background Art

[0002] During building construction, a shaft is typically created. This shaft, in addition to being used for the subsequent installation of the building's elevator, also facilitates the transportation of construction materials during construction. Before materials can be transported through the shaft, the shaft must first be constructed. A shaft is typically a vertical passageway enclosed by concrete walls. Construction materials can be placed in a hoist cage, which is raised and lowered along the shaft to transport them to different levels. Traditional shaft construction involves using inner and outer shaft formwork to create a space, which is then poured with concrete to form the shaft walls. The inner and outer forms work together, moving upwards to construct the next level after each layer is completed. The inner formwork is also equipped with a construction platform and a lifting device for raising the platform. The platform is raised along with the inner formwork by the lifting device, allowing workers to stand on the platform and install bolts to secure the inner and outer forms. Therefore, because the lifting device takes up space in the shaft, equipment such as the hoist cage cannot be installed until the shaft is complete. Therefore, the shaft construction and material transportation have to be carried out in sequence. In addition to the additional construction equipment such as the construction platform and the lifting device, this construction method also prolongs the construction period.

[0003] Secondly, the existing inner formwork is generally lifted by an electric hoist and a wire rope. The wire rope lifting makes the inner formwork unstable and unsafe, which brings great safety hazards to the construction.

[0004] Furthermore, in order to ensure the stable lifting and lowering of the cage, guide rails are usually installed on the inner wall of the shaft so that the cage can move along the guide rails, making the cage movement more stable. Similarly, the guide rail installation equipment can only be installed after the shaft is completely built. It can be seen that the existing shaft material transportation usually has two sets of mechanisms. One set of mechanisms is the guide rail installation mechanism, which includes an installation platform, a suspension beam and an electric hoist. The electric hoist is installed on the suspension beam, and the electric hoist is connected to the installation platform through a wire rope. The other set of mechanisms is the material conveying mechanism, which includes a cage, a sky beam, a traction machine and an electric control cabinet. The traction machine and the electric control cabinet are generally placed on the sky beam, and the traction machine is connected to the cage through a wire rope. Among them, the installation platform is set above the cage, and the worker stands on the installation platform to perform the guide rail installation operation on the inner wall of the shaft so that the cage can climb up along the guide rail. The traditional way of lifting these two sets of mechanisms is to use electric hoists to drive the lifting, that is, the electric hoists drive the installation platform and the sky beam to lift respectively, but before each lifting, workers are required to move the suspension beam to the upper level, which is not only unsafe, but also time-consuming and labor-intensive.

[0005] Existing building construction machines include a lifting mechanism and a support frame connected to the lifting mechanism. A top beam and an electric hoist are mounted on the support frame, respectively. The lifting mechanism drives the support frame upward, driving both mechanisms to raise the building. This eliminates the need for workers to carry the suspended beam to raise the building, which is both safer and more time- and labor-saving. However, this structure presents the following problems: 1. The lifting platform and cage are unsafe and unstable. The installation platform is connected to the electric hoist via a wire rope. The wire rope lifting causes the installation platform to sway, resulting in poor stability and safety, posing a significant safety hazard during construction. 2. The cage is connected to a traction machine via a wire rope. The traction machine is mounted on the support frame, and the cage is located below the installation platform. The large distance between the cage and the support frame and the long wire rope make it more prone to cage sway and other instability, resulting in insufficient stability and safety. 3. Cage collision. The traction machine is mounted on the support frame via the top beam, and the support frame is located above the building. If the traction machine fails, the cage could fly from the top of the shaft out of the building, potentially causing a safety hazard. 3. The installation platform is unstable when it is raised or lowered. The existing installation platform only has a base plate and a fence around the base plate, and there is no connection structure with the well. When workers are working on the installation platform, it is easy to shake, which not only affects the work but also reduces safety. Summary of the Invention

[0016] The hoistway template mechanism includes a plurality of inner templates, and the inner templates are arranged along the edge of the top plate;

[0017] The areas of the top plate and the bottom plate are both larger than the cross-sectional area of the side frame.

[0018] As an improvement to the above solution, the support platform includes support bars;

[0019] The shaft construction device further comprises an adjusting mechanism for adjusting the relative position between the supporting platform and the connecting member, wherein the adjusting mechanism comprises a connecting bar, which is movably connected to the connecting member and the supporting bar respectively.

[0020] As an improvement to the above solution, a preset angle is formed between the connecting bar and the supporting bar;

[0021] The adjustment mechanism further includes a first connecting claw and a second connecting claw. The connecting bar is movably connected to the support bar via the first connecting claw, and the connecting bar is movably connected to the connecting member via the second connecting claw.

[0025] Correspondingly, the present invention also provides a building construction machine, comprising a lifting mechanism and the above-mentioned shaft construction device, wherein the lifting mechanism is connected to the support platform.

[0026] Accordingly, the present invention also provides a construction method of the above-mentioned shaft construction device, including the installation step of the shaft construction device, and the installation step includes the following steps:

[0027] (1) First place the support platform above the shaft, and then install the connector on the support platform;

[0029] (3) Install the well template mechanism on the top of the installation carrier;

[0034] The implementation of the present invention has the following beneficial effects:

[0035] 1. The mounting carrier in the shaft construction device of the present invention is rigidly connected to a support platform above the shaft via a connector. Compared with existing wire rope connections, the mounting carrier is less prone to shaking, has better stability, and is highly installable. Simultaneously, the support platform is driven by the lifting mechanism of the building construction machine to ascend, driving the mounting carrier along with it. This eliminates the need for manual lifting, saving time and effort.

As the support platform drives the installation carrier to ascend, it also drives the conveying drive mechanism to ascend. Similarly, no manual lifting is required. The simple structure improves construction efficiency and shortens the construction period. Furthermore, compared with existing structures in which the conveying drive mechanism is mounted on a support frame, the present invention shortens the distance between the conveying drive mechanism and the hoistway elevator, which in turn shortens the length of the wire rope, making the lifting more stable and improving the stability of the hoistway elevator, thereby enhancing the safety of construction material transportation.

[0037] 3. The shaft template mechanism is mounted on top of the mounting carrier, which supports the shaft template mechanism and drives it to ascend. This eliminates the need for additional electric hoists and wire ropes to lift the shaft template, eliminating some construction equipment and reducing construction costs. The structure is simple, stable, and highly safe. Furthermore, the shaft template mechanism stabilizes the mounting carrier, further reducing or even preventing its shaking, thereby improving the safety of the present invention.

[0038] 4. The installation carrier also provides a construction platform for the shaft formwork mechanism. Workers can stand on top of the installation carrier to install bolts on the shaft formwork mechanism, fix the inner and outer formwork together, and then pour concrete between them to form the shaft wall. This eliminates the need for a construction platform and a lifting device, reducing construction costs. Based on the above structure, the shaft formwork mechanism, the installation carrier, and the shaft elevator are arranged in sequence from top to bottom. Then, when the shaft formwork mechanism is building the shaft wall, workers can enter the installation carrier to install the guide rails on the shaft wall that has been built below the shaft formwork mechanism, while the shaft elevator can be raised and lowered in the shaft space below the installation carrier to transport construction materials. Therefore, guide rail installation and material transportation do not need to wait until the shaft is completely built. Shaft construction, guide rail installation, and material transportation can be carried out simultaneously. In addition to reducing construction costs, it also greatly shortens the construction period. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0050] See also Figure 1-8 The present invention discloses a shaft construction device, comprising a support platform 1, a shaft template mechanism 8, an installation mechanism and a conveying mechanism, wherein the support platform 8 is arranged above the shaft 101. That is, the support platform 8 is arranged above the shaft 101 of the building 100.

[0051] The mounting mechanism includes a mounting carrier 2, which is rigidly connected to the support platform 1 via a connector 3 and is suspended below the support platform 1; the hoistway template mechanism 8 is mounted on the top of the mounting carrier 2. The connector 3 is preferably a square tube vertical rod.

[0052] The conveying mechanism includes a hoistway elevator 4 and a conveying drive mechanism. The hoistway elevator 4 and the conveying drive mechanism are connected, and the hoistway elevator 4 is suspended below the conveying drive mechanism; the conveying drive mechanism is installed at the bottom of the installation carrier 2.

[0053] The implementation of the present invention has the following beneficial effects:

[0054] 1. The mounting carrier in the shaft construction device of the present invention is rigidly connected to a support platform above the shaft via a connector. Compared with existing wire rope connections, the mounting carrier is less prone to shaking, has better stability, and is highly installable. Simultaneously, the support platform is driven by the lifting mechanism of the building construction machine to ascend, driving the mounting carrier along with it. This eliminates the need for manual lifting, saving time and effort.

[0055] 2. The conveying drive mechanism of the conveying mechanism is installed at the bottom of the installation carrier. As the support platform drives the installation carrier to ascend, it also drives the conveying drive mechanism to ascend. Similarly, no manual lifting is required. The simple structure improves construction efficiency and shortens the construction period. Furthermore, compared with existing structures in which the conveying drive mechanism is mounted on a support frame, the present invention shortens the distance between the conveying drive mechanism and the hoistway elevator, which in turn shortens the length of the wire rope, making the lifting more stable and improving the stability of the hoistway elevator, thereby enhancing the safety of construction material transportation.

[0056] 3. The shaft template mechanism is mounted on top of the mounting carrier, which supports the shaft template mechanism and drives it to ascend. This eliminates the need for additional electric hoists and wire ropes to lift the shaft template, eliminating some construction equipment and reducing construction costs. The structure is simple, stable, and highly safe. Furthermore, the shaft template mechanism stabilizes the mounting carrier, further reducing or even preventing its shaking, thereby improving the safety of the present invention.

[0057] 4. The installation carrier also provides a construction platform for the shaft formwork mechanism. Workers can stand on top of the installation carrier to install bolts on the shaft formwork mechanism, fix the inner and outer formwork together, and then pour concrete between them to form the shaft wall. This eliminates the need for a construction platform and a lifting device, reducing construction costs. Based on the above structure, the shaft formwork mechanism, the installation carrier, and the shaft elevator are arranged in sequence from top to bottom. Then, when the shaft formwork mechanism is building the shaft wall, workers can enter the installation carrier to install the guide rails on the shaft wall that has been built below the shaft formwork mechanism, while the shaft elevator can be raised and lowered in the shaft space below the installation carrier to transport construction materials. Therefore, guide rail installation and material transportation do not need to wait until the shaft is completely built. Shaft construction, guide rail installation, and material transportation can be carried out simultaneously. In addition to reducing construction costs, it also greatly shortens the construction period.

[0058] Specifically, such as Figure 1 、 4 As shown, the mounting carrier 2 includes a side frame 22, a top plate 23 provided at the top end of the side frame 22, and a bottom plate 21 provided at the bottom end of the side frame 22. The connecting member 3 is fixedly connected to the top plate 23, and the shaft template mechanism 8 is fixedly installed on the top plate 23; the conveying drive mechanism is fixedly installed on the bottom plate 21.

[0059] An installation space is defined between the side frames, top plate, and bottom plate. Workers enter this installation space to install the guide rails on the inner wall of the shaft. Accordingly, the side frame walls are provided with openings facing the inner wall of the shaft, making it easier for workers to install the guide rails. Furthermore, the side frames, top plate, and bottom plate provide protection for workers within the installation space, ensuring high safety. The connectors are fixedly connected to the top plate, simplifying installation and connection. The installation carrier is connected to the support platform via connectors and is driven by the support platform to ascend. Secondly, the installation carrier drives the shaft formwork mechanism to ascend. The shaft formwork mechanism constructs the shaft above the installation carrier, while the installation carrier installs the guide rails below the shaft formwork mechanism. The two processes do not interfere with each other and can be carried out simultaneously, improving construction efficiency and shortening the construction period. At the same time, due to the small gap between the shaft formwork mechanism and the shaft wall, it acts as a limiter for the installation carrier, reducing or even preventing the installation carrier from shaking, thus ensuring good stability and high safety. Finally, the top plate can be used as a construction platform for workers to stand and perform construction operations such as installing bolts in the shaft template mechanism, eliminating the need to set up an additional construction platform. The structure is simple and compact, and the construction cost is low.

[0060] It should be noted that the shaft formwork mechanism 8 includes several inner formworks, which are arranged along the edge of the top plate 23, and two adjacent inner formworks are fixedly connected. The floor layer of the building is provided with outer formworks corresponding to the inner formworks. The inner and outer formworks enclose a space, and then concrete is poured into this space to form the shaft wall.

[0061] Preferably, the areas of the top plate 23 and bottom plate 21 are both larger than the cross-sectional area of the side frame 22. That is, the gaps between the top and bottom plates and the shaft wall are relatively small, limiting the mounting support from the top and bottom, which helps reduce the shaking of the mounting support. Meanwhile, the gaps between the side frame and the shaft wall are relatively large, leaving sufficient space for workers to install the guide rails on the shaft wall.

[0062] Among them, Figure 4-5 As shown, the conveying drive mechanism includes a mounting platform 5 and a traction machine 6 mounted on the mounting platform 5. The mounting platform 5 is mounted on a base plate 21. The traction machine 6 is connected to the shaft elevator 4 via a steel wire rope 7. Through holes are provided on both the mounting platform and the base plate, and the steel wire rope passes through the through holes so that the shaft elevator is suspended below the mounting carrier. The traction machine drives the shaft elevator to rise and fall in the shaft space below the mounting carrier via the steel wire rope, so as to facilitate the transportation of construction materials between floors. The base plate plays the role of supporting the installation of the conveying drive mechanism. Compared with the existing structure in which the conveying drive mechanism is arranged on a support frame, the present invention shortens the distance between the conveying drive mechanism and the shaft elevator, that is, shortens the length of the steel wire rope, makes the lifting more stable, improves the stability of the shaft elevator, and thus improves the safety of the construction material transportation.

[0063] The base plate also prevents the hoistway elevator from collapsing in the event of a traction motor failure, significantly improving the safety of the hoistway elevator. The conveying drive mechanism also includes an electrical control cabinet, which is housed within the hoistway elevator. Conventional electrical control cabinets are typically placed on mounting platforms. However, due to the improved safety of the hoistway elevator of the present invention, which can even be used to transport passengers, the electrical control cabinet is placed within the hoistway elevator to facilitate control of the hoistway elevator's movements.

[0064] Preferably, the connector 3 is made of a rigid material. More preferably, the rigid material is steel, but is not limited thereto. The rigid material provides a rigid connection between the support platform and the mounting carrier, reducing sway in the mounting carrier and making the mounting carrier more stable and reliable within the hoistway. A "rigid connection" is a connection method that virtually prevents relative displacement and rotation between the connected components. A "rigid material" is a material that undergoes minimal or no deformation under the action of external forces.

[0065] Preferably, if Figure 3-4 As shown, the top plate 23 is provided with a connecting base 9, which includes at least two connecting blocks 91, and the connecting blocks 91 are not on the same plane; the connecting member 3 and the connecting blocks 91 are fixedly connected. The arrangement of multiple connecting blocks that are not on the same plane allows the connection between the connecting member and the connecting block on the connecting base to be selected based on the different positions between the mounting carrier and the connecting member, thereby simplifying installation and increasing installation flexibility. More preferably, the connecting base is made of a rigid material, and the rigid material is steel. Specifically, the two connecting blocks 91 are arranged at 90 degrees to each other.

[0066] Further, if Figure 1-2 As shown in Figures 8 and 9, the support platform 1 includes a support bar 1a, which is arranged horizontally above the shaft 101. The shaft construction device also includes an adjustment mechanism for adjusting the relative position between the support platform 1 and the connecting member 3. The adjustment mechanism includes a connecting bar 10, which is movably connected to the connecting member 3 and the support bar 1a.

[0067] Because the connector is made of rigid material and cannot deform, if the relative position between the hoistway and the support platform is not very precise, it may cause one side of the mounting carrier to collide and rub against the hoistway wall, affecting the mounting carrier's movement up the floor. Therefore, the present invention provides an adjustment mechanism that can adjust the relative position between the support platform and the connector based on the position between the hoistway and the support platform, so that the mounting carrier is centered on the hoistway cross-section, avoiding friction between the mounting carrier and the hoistway wall. The present invention uses a connecting bar to adjust the relative position between the connector and the support bar.

[0068] Preferably, if Figure 2As shown, the connecting bar 10 and the support bar 1a form a preset angle, which can adjust the relative position between the connecting member and the support platform from different directions. The adjustment mechanism also includes a first connecting claw 11 and a second connecting claw 12. The connecting bar 10 is movably connected to the support bar 1a via the first connecting claw 11, and the connecting bar 10 is movably connected to the connecting member 3 via the second connecting claw 12, so that the relative position between the connecting member and the support platform can be adjusted from different directions.

[0069] More preferably, the preset angle is 90 degrees, that is, the support bar 1a and the connecting bar 10 are arranged perpendicular to each other. If the support bar is arranged horizontally, the connecting bar is arranged vertically.

[0070] like Figure 2 As shown, the first connecting claw 11 comprises a first upper claw 111 and a lower claw 112. The connecting bar 10 comprises a connecting body 101 and a clamping bar 102 disposed on the connecting body 101. The second connecting claw 12 comprises a second upper claw 121 and a fixed connecting body 122. There are at least two clamping bars 102, one on each side of the connecting body 101. The two clamping bars are arranged parallel to each other and are perpendicularly connected to the connecting body. The cross-section of the connecting bar 10 is an I-shaped bar.

[0071] The first upper claw 111 is secured to and slidably connected to the support bar 1a. The lower claw 112 is secured to and slidably connected to the clamping bar 102. The second upper claw 121 is secured to and slidably connected to the clamping bar 102. The fixed connector 122 is fixedly connected to the connector 3. Specifically, the first upper claw can slide along the support bar, and the lower claw can slide along the upper clamping bar of the connecting bar. Thus, the first upper claw adjusts the connector's connection position on the support bar, achieving horizontal position adjustment. The lower claw and the connecting bar cooperate to adjust the connector's connection position perpendicular to the support bar, i.e., longitudinal position adjustment. The second upper claw can slide along the lower clamping bar of the connecting bar. Thus, the second connecting claw adjusts the connector's connection position on the connecting bar, balancing the forces on the connecting bar and ensuring a secure connection between the connector and the connecting bar.

[0072] Preferably, there are two adjustment mechanisms, each comprising two first connecting claws 11, a connecting bar 10, and two second connecting claws 12. Accordingly, there are two support bars 1a, arranged parallel to each other, with the two connecting bars 10 corresponding to the first connecting claws 11. There are two connectors 3, with the connectors 3 and the second connecting claws 12 corresponding to each other. There are two connecting seats 9, with the connectors 3 and the connecting seats 9 corresponding to each other. The connecting bars 10 of the two adjustment mechanisms are arranged parallel to each other. The arrangement of the two adjustment mechanisms balances the forces on the support platform, thereby ensuring a stable, reliable, and secure connection between the support platform and the mounting carrier.

[0073] Specifically, such as Figure 2 As shown, the two ends of the connecting body 101 are respectively provided with a limit block 103, which limits the first connecting claw and the second connecting claw to prevent the first connecting claw and the second connecting claw from being separated from the connecting bar.

[0074] Accordingly, see Appendix Figure 1-8 The present invention also discloses a building construction machine comprising a lifting mechanism 200 and the aforementioned shaft construction device. The lifting mechanism 200 is connected to the support platform 1. The specific structure of the shaft construction device is described above and will not be repeated here. The lifting mechanism drives the support platform upward, which in turn drives the shaft formwork mechanism, installation mechanism, and conveying mechanism to ascend.

[0075] Accordingly, see Figure 9 The present invention also discloses a construction method of the above-mentioned well construction device. The specific structure of the well construction device is as described above and will not be repeated here.

[0076] The construction method includes the steps of installing the shaft construction device, and the installation step includes the following steps:

[0077] S101. First place the support platform above the shaft, and then install the connecting parts on the support platform.

[0078] It should be noted that before step S101 , the shaft wall of at least the first floor should be built on the ground, and then the supporting platform should be placed above the shaft, and then the connecting parts should be installed on the supporting platform.

[0079] Step S101 includes: installing the adjustment mechanism on the support bar of the support platform, and then connecting the adjustment mechanism to one end of the connecting member.

[0080] S102, assembling the installation carrier in the hoistway, and fixing the connecting piece and the installation carrier together.

[0081] The step of "assembling and installing the carrier in the shaft" includes: installing the conveying drive mechanism on the bottom plate in the shaft, and then installing the bottom plate and the top plate on the bottom and top ends of the side frame respectively.

[0082] The step of "fixedly connecting the connecting member and the mounting carrier" includes: fixedly connecting the other end of the connecting member to the connecting seat of the top plate.

[0083] S103, installing the shaft template mechanism on the top of the mounting carrier. That is, fixing the inner templates on the top plate of the mounting carrier respectively, specifically, placing each inner template along the edge of the top plate.

[0084] After step S103 , the process includes: installing a hoistway elevator guide rail in the hoistway.

[0085] S104: After the support platform is driven to raise the installation platform to a preset height, the hoistway elevator is assembled in the hoistway and connected to the conveyor drive mechanism. The lifting mechanism drives the support platform upward, driving the installation carrier to rise off the ground. The hoistway elevator is then assembled in the hoistway, below the installation carrier. The electrical control cabinet is installed in the hoistway elevator, and the hoistway elevator is connected to the traction machine and the guide rails using steel wire ropes.

[0086] Finally, check the connection strength of each component to ensure a secure installation and stable function.

[0087] The installation steps of the shaft construction device of the present invention are based on the installation carrier. First, the installation carrier and the support platform are connected to fix the installation carrier. Then, the shaft template mechanism is installed on the top of the installation carrier, the shaft elevator is set below the installation carrier, and then the shaft elevator and the traction machine on the installation carrier are connected. Since the installation carrier and the support platform have been connected, when the shaft template mechanism and the shaft elevator are installed on the installation carrier, the installation connection is reliable and stable, the position is not easy to shift, and the installation is simple and fast. Compared with the existing shaft construction device, since some equipment such as the setting of the construction platform is omitted, there are fewer installation parts, which makes the installation efficiency high and greatly shortens the construction period. Moreover, the assembly of the installation carrier and the shaft elevator is carried out on the ground, avoiding high-altitude operations, reducing construction risks, and improving safety.

[0088] Further, see Figure 10 The construction method of the above-mentioned shaft construction device further includes a disassembly step of the shaft construction device, and the disassembly step includes the following steps:

[0089] S201, start the conveying drive mechanism, lower the hoistway elevator to the ground for disassembly, and disconnect the hoistway elevator from the conveying drive mechanism. Specifically, after the hoistway elevator is lowered to the ground in the hoistway by controlling the traction machine, the connection between the hoistway elevator and the traction machine is disconnected.

[0090] Step S201 includes: disconnecting the power cord, disassembling and recovering the wire rope, disassembling the hoistway elevator, and removing the hoistway guide rails.

[0091] S202, lifting the support platform, the installation mechanism and the shaft template mechanism together, and placing them on the ground for dismantling. Specifically, using a tower crane to lift the support platform, the installation mechanism and the shaft template mechanism together, and placing them on the ground, the support platform, the installation mechanism and the shaft template mechanism are dismantled one by one.

[0092] In the disassembly process of the shaft construction device of the present invention, all parts are disassembled on the ground, avoiding high-altitude work, reducing construction risks, and improving safety. Moreover, its disassembly is simple and convenient, greatly shortening the construction period.

[0093] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
