Description

Technical Field

[0001] This invention relates to an elevator installation technology, and more specifically, to an elevator shaft template frame and its installation method. Background Technology

[0002] Currently, most villa staircase installations using a frame system are done in stages: the frame is installed first, and then the elevator components are installed after the client completes the renovation. This traditional method has many drawbacks: disassembling and assembling the frame requires more labor costs and is extremely inconvenient to use; the pre-installed frame hinders clients from moving large furniture, affecting the ease of climbing stairs; the frame also increases the difficulty of decorating the sides of the staircase, extending the renovation period; furthermore, due to the time difference between frame installation and elevator component installation, dedicated personnel are needed to protect the frame, further incurring additional labor costs.

[0003] For example, Chinese Patent Publication No. CN218346900U, published on January 20, 2023, discloses a utility model entitled "An Elevator Shaft Positioning Template Frame." This application discloses a template frame structure for an elevator shaft, including a positioning base plate, a first column, a second column, a first extension arm, a second extension arm, a first rope, and a second rope. The first and second columns are arranged opposite each other and both connected to the positioning base plate. The end of the first column away from the positioning base plate is connected to the first extension arm, which is connected to the positioning base plate via the first rope. The end of the second column away from the positioning base plate is connected to the second extension arm, which is connected to the positioning base plate via the second rope. The first column, second column, first rope, and second rope together enclose the space occupied by the elevator shaft. This solution provides an elevator shaft positioning template frame that can enclose the space occupied by the elevator shaft, avoiding interference during later installation and ensuring the construction period. However, the structure of this solution is complex. It arranges some of the elevator frame columns as part of the template frame in the elevator shaft, which makes the arrangement of the columns difficult and hinders the disassembly and assembly of the template frame. Furthermore, since the columns are rigid structures, it may affect the initial experience of some users. Summary of the Invention

[0004] This invention overcomes the problems of complex structure and inconvenient disassembly and assembly of existing elevator shaft template frames, and provides an elevator shaft template frame and its installation method. The template frame structure of this solution is simple, easy to disassemble and assemble, and applicable to more scenarios. The installation method is simple and convenient, and can reduce the consumption of manpower and material resources.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an elevator shaft template frame, comprising a fixed bracket at the top of the shaft and a plurality of pit brackets at the bottom of the shaft. The fixed bracket is an adjustable bracket, and a connecting rope is provided between the fixed bracket and the pit brackets. At least one end of the connecting rope is adjustablely connected to the fixed bracket and the pit brackets. The connecting rope is provided with a tensioning component, and the connecting rope is arranged vertically and parallel. In this solution, the area of ​​the elevator shaft can be enclosed simply by setting a connecting rope between the fixed bracket at the top of the shaft and the pit brackets at the bottom of the shaft, thus forming a constrained space for the corresponding shaft instead of a frame. Through the elastic adjustable connection and tensioning component between the connecting rope and the fixed bracket or pit bracket, the connecting rope can be kept taut, preventing displacement. This solution allows the elevator shaft frame and elevator operating components to be installed simultaneously after the template is installed and the customer's renovation is completed, reducing the cost of multiple transportation and installations.

[0006] Preferably, the fixed support includes a main support, which comprises a first support and a second support, wherein the first support and the second support are slidably and adjustablely connected along their length. The main support serves as the base support, and the sliding adjustment between the first and second supports allows for dimensional adjustment along the length direction, improving the applicability of the template rack.

[0007] Preferably, the fixed bracket further includes a secondary bracket perpendicular to the main bracket. The secondary bracket includes a third bracket and a fourth bracket, and the third bracket and the fourth bracket are slidably and adjustablely connected along their length. The slidable and adjustable connection between the third bracket and the fourth bracket allows for adjustment of the size of the template frame in the width direction, improving the applicability of the template frame.

[0008] Preferably, the first support and the second support are C-shaped channel steel, and the first support or the second support is provided with a first adjustment groove, which is arranged along the length direction of the first support and the second support. The first adjustment groove can be arranged on the first support or the second support, and the first adjustment groove is in the shape of an elongated hole.

[0009] Preferably, the first bracket is provided with a first inclined groove, and the second bracket is provided with a second inclined groove. The first inclined groove and the second inclined groove have opposite inclination directions, and a fastener is provided between the first inclined groove and the second inclined groove. The first inclined groove and the second inclined groove have opposite inclination directions. When they overlap, they form a connecting hole structure. Connecting the two with the fastener can improve the fixing strength of the first bracket and the second bracket.

[0010] Preferably, the main support and the secondary support are fixedly connected, the third support and the fourth support are C-shaped channel steel, and the third support or the fourth support is provided with a second adjustment groove, which is arranged along the length direction of the third support and the fourth support. The second adjustment groove can be arranged on the third support or the fourth support, and the second adjustment groove is in the shape of an elongated hole.

[0011] Preferably, the tensioning assembly includes an adjusting member, a connecting member, and an elastic member. The adjusting member is connected to the pit support; the connecting member is connected to the connecting rope; one end of the elastic member is fixedly connected to the adjusting member, and the other end is fixedly connected to the connecting frame. The tensioning assembly can be used to tighten and straighten the installed connecting rope. The adjusting member can adjust the vertical accuracy of the connecting rope, and the elastic member can buffer the connecting rope and also has a restoring effect.

[0012] Preferably, the connector includes a conical sleeve connected to the connecting rope, and a connecting rod is fixed to the end of the conical sleeve away from the connecting rope. Using a connecting conical sleeve and a connecting rod to fix the connecting rope ensures coaxiality between the connecting rope, the conical sleeve, and the connecting rod, preventing displacement of the connecting rope and guaranteeing its positional accuracy.

[0013] Preferably, the pit support is a Z-shaped support, comprising a first connecting surface and a second connecting surface, wherein the first connecting surface and the second connecting surface are respectively provided with a first connecting groove and a second connecting groove that are perpendicular to each other. The first connecting surface and the second connecting surface are the bottom surface and the top surface of the pit support, and the first connecting groove and the second connecting groove are in the shape of elongated slots. The perpendicularity of the first connecting groove and the second connecting groove allows for adjustment of the position of the adjusting component in the depth direction (from elevator car door to car back) and the width direction of the shaft.

[0014] Preferably, the connecting rope is equipped with a card, which is adjustable and connected to the connecting rope in the vertical direction. The card can record various key data of the elevator shaft, facilitating subsequent review and verification by construction personnel.

[0015] A method for installing an elevator shaft template frame includes the following steps: S1: Assemble the template frame by adjusting the first and second supports to appropriate positions, fixing the third support to the second support, ensuring the diagonal of the third support is accurate, and fixing the fourth support at both ends of the third support, ensuring both are horizontal; S2: Install connecting ropes by fixing the connecting ropes to the fourth support and the pit support; S3: Fix the template frame by fixing the assembled template frame to the top of the elevator shaft; S4: Tension the connecting ropes by adjusting the tensioning components to make the connecting ropes taut. This method is simple to operate, allowing the template frame to be assembled in advance and then directly installed and arranged in the elevator shaft, effectively reducing the installation difficulty of the template frame in the elevator shaft and improving installation efficiency.

[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) It can be applied to the layout of all sightseeing shaft elevators. Only the template frame needs to be adjusted according to the width and depth of the civil engineering elevator, and the scope of use and scenarios are wider; (2) The width can be adjusted in two directions according to the on-site dimensions. One template frame can meet the use of most shaft dimensions; (3) The bottom wire rope is connected to the anti-sway wire rope cone sleeve, so that the screw and spring connected to the wire rope are tensioned, so that the wire rope is straight. In the event of an external force collision, the wire rope can also be reset by the rotation force of the spring; (4) There is a positioning pin between the main support and the auxiliary support, which can make the channel steel assembly accurately positioned, meet the diagonal requirements, and make the wire rope layout more accurate; (5) The ease of disassembly and assembly of the template frame greatly reduces the difficulty of disassembly and assembly of the template frame and reduces labor costs.

[0023] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0024] Example: Figures 1 to 5The elevator shaft template frame shown includes a fixed support 1 and a pit support 2. The fixed support 1 is located at the top of the elevator shaft, and the pit support 2 is located at the bottom of the elevator shaft. A connecting rope 3 is provided between the fixed support 1 and the pit support 2, and the connecting rope 3 is arranged vertically. In this embodiment, four sets of pit supports 2 are arranged in a rectangular pattern. Four sets of connecting ropes 3 are connected to the fixed support 1 and the four sets of pit supports 2, thereby enclosing the area of ​​the elevator shaft. By using connecting ropes 3 to form a constrained space in the elevator shaft, the use of a frame is replaced, reducing the layout of the elevator shaft template frame and also reducing the maintenance cost of the elevator shaft template frame.

[0025] Specifically, the fixed bracket 1 includes two types: a main bracket 1.1 and a secondary bracket 1.2. The main bracket 1.1 is arranged along a first direction, and the secondary bracket 1.2 is arranged along a second direction. The first direction and the second direction are perpendicular to each other. In this embodiment, the first direction is defined as the depth direction of the elevator shaft (from the elevator car door to the back of the car), and the second direction is the width direction of the elevator shaft. In this embodiment, the arrangement of the template frame is taken as an example of a villa elevator shaft.

[0026] A fixed bracket 1 is positioned at the top of the elevator shaft. The main bracket 1.1 is fixedly connected to the top floor slab 5 of the elevator shaft, while the auxiliary bracket 1.2 is used to suspend the connecting rope 3. Two sets of main brackets 1.1 are provided, arranged in parallel. Each main bracket 1.1 includes a first bracket 1.1.1, a second bracket 1.1.2, and a fixing frame. All three are arranged along a first direction, and the connection between the first bracket 1.1.1 and the second bracket 1.1.2 is adjustable, meaning the overall length of the main bracket 1.1 can be changed. The fixing frame is fixedly connected to the first bracket 1.1.1. Specifically, one set of the first bracket 1.1.1, one set of the second bracket 1.1.2, and one set of the fixing frame are provided, with the second bracket 1.1.2 and the fixing frame respectively located at both ends of the first bracket 1.1.1. Furthermore, a first adjustment groove 4 is provided on the second bracket 1.1.2, located close to the first bracket 1.1.1. The first adjustment groove 4 is oblong in shape. A corresponding connecting hole is provided on the first bracket 1.1.1. By connecting the connecting hole on the first bracket 1.1.1 and the first adjustment groove 4 on the second bracket 1.1.2 with bolts or other fasteners, the first bracket 1.1.1 and the second bracket 1.1.2 can be fixed together. Before fixing the first bracket 1.1.1 and the second bracket 1.1.2, their positions need to be adjusted to ensure the accurate length of the main bracket 1.1. The first adjustment groove 4 can also be arranged on the first bracket 1.1.1. Specifically, the first bracket 1.1.1 has a first adjustment groove 4, which is located close to the second bracket 1.1.2. The first adjustment groove 4 is oblong. The second bracket 1.1.2 has a corresponding connecting hole, which is located close to the first bracket 1.1.1. By connecting the first adjustment groove 4 on the first bracket 1.1.1 and the connecting hole on the second bracket 1.1.2 with bolts or other fasteners, the first bracket 1.1.1 and the second bracket 1.1.2 can be fixed together. Furthermore, the fixing frame is located at the end of the first bracket 1.1.1 away from the second bracket 1.1.2 and is fixedly connected to the top floor slab surface with bolts.

[0027] Furthermore, the main support 1.1 adopts a C-shaped channel steel structure, meaning that the first support 1.1.1, the second support 1.1.2, and the fixing frame are all C-shaped channel steel. The C-shaped cross-sectional area of ​​the first support 1.1.1 is larger than that of the second support 1.1.2, and the internal dimensions of the first support 1.1.1 are adapted to the external dimensions of the second support 1.1.2. This allows the second support 1.1.2 to be embedded into the first support 1.1.1 along the first direction, enabling sliding adjustment between them. When the length between the first support 1.1.1 and the second support 1.1.2 is adjusted appropriately, they can be locked in place using fasteners. The C-shaped cross-sectional area of ​​the fixing frame is smaller than that of the first support 1.1.1. The fixing frame is inserted into the first support 1.1.1 and then locked in place using locating pins. Further welding can also be used for fixation.

[0028] In this embodiment, since the main support 1.1 needs to be fixed to the top floor slab 5 of the elevator shaft, and the first support 1.1.1 is located between the second support 1.1.2 and the fixing frame, only the fixing frame can be connected to the top floor slab 5 of the elevator shaft. Specifically, one end of the fixing frame is arranged on the platform 5 at the top of the elevator shaft, and bolt holes are provided on the side of the fixing frame away from the first support 1.1.1. The bolt holes are bolted to the top floor slab 5 of the elevator shaft, and the bolt holes are also oblong holes to facilitate the adjustment of the fixing frame on the top floor slab 5 of the elevator shaft. For the second support 1.1.2, since the main support 1.1 has two sets, the side of the main support 1.1 away from the top floor slab 5 of the elevator shaft has two sets of second supports 1.1.2. The ends of the two sets of second supports 1.1.2 away from the first support 1.1.1 are fixedly connected by a connecting frame 1.1.3 (using pins) to form a U-shaped support. The connecting frame 1.1.3 is also a C-shaped channel steel structure. In this way, the two sets of main supports 1.1 are fixedly connected together to form a whole, and the second support 1.1.2 on the side away from the top floor slab 5 of the elevator shaft is in a suspended state. Similarly, in order to further improve the stability of the main support 1.1, the two fixing frames on the side closer to the top floor slab 5 of the elevator shaft can also be fixedly connected by the connecting frame 1.1.3.

[0029] The first support 1.1.1 and the second support 1.1.2 are both C-shaped channel steel structures. Two sets of main supports 1.1 are provided, and the two sets of main supports 1.1 are arranged in parallel. The first support 1.1.1, the second support 1.1.2, and the fixing frame on the two sets of main supports 1.1 are arranged opposite each other, with the channel openings facing each other. Thus, the bottom of the first support 1.1.1, the second support 1.1.2, and the fixing frame is one side of the channel steel (arranged horizontally), the top of the first support 1.1.1, the second support 1.1.2, and the fixing frame is one side of the channel steel (arranged horizontally), and the middle part of the first support 1.1.1, the second support 1.1.2, and the fixing frame is the opening and bottom surface of the channel (arranged vertically). The bottom side of the fixing frame can be fixedly connected to the top floor slab 5 of the elevator shaft. The top side of the second support 1.1.2 and the top side of the fixing frame can be used to support the auxiliary support 1.2.

[0030] In this embodiment, the use of C-shaped channel steel for the first bracket 1.1.1, the second bracket 1.1.2, and the fixing frame significantly reduces the weight of the main bracket, achieving the lightweight requirement of the elevator shaft template frame. The slots of the first bracket 1.1.1, the second bracket 1.1.2, and the fixing frame are arranged opposite each other, ensuring that the second bracket 1.1.2 and the fixing frame have mounting surfaces on both the upper and lower sides, enabling connection with the top floor slab 5 of the elevator shaft and the auxiliary bracket 1.2. The U-shaped bracket formed by the connecting frame 1.1.3 and the second bracket 1.1.2 can be completely inserted into the first bracket 1.1.1, facilitating the transportation of the entire template frame.

[0031] A first inclined groove 6.1 is provided on the first bracket 1.1.1, and a second inclined groove 6.2 is provided on the second bracket 1.1.2. The first inclined groove 6.1 and the second inclined groove 6.2 are located on the bottom surface of the channel steel (arranged vertically). Both the first inclined groove 6.1 and the second inclined groove 6.2 are elongated holes. The width of the first inclined groove 6.1 and the second inclined groove 6.2 is adapted to the radial dimension of the fastener. The fastener is a connecting bolt. When the first bracket 1.1.1 and the second bracket 1.1.2 are connected together, the first inclined groove 6.1 and the second inclined groove 6.2 will overlap, that is... The first inclined groove 6.1 and the second inclined groove 6.2 are arranged in a cross pattern, and a fixing hole adapted to the fastener is formed between the first inclined groove 6.1 and the second inclined groove 6.2. Through the fixed connection of the fastener, the first bracket 1.1.1 and the second bracket 1.1.2 can be further fixedly connected. The first bracket 1.1.1 and the second bracket 1.1.2 can be completely fixed in the length direction, preventing the first bracket 1.1.1 and the second bracket 1.1.2 from displacement deviation in the depth direction (first direction) due to the loose connection of the first adjusting groove 4, and ensuring the positional accuracy of the connecting rope 3.

[0032] Two sets of secondary supports 1.2 are also provided, and are respectively arranged at both ends of the length direction of the main support 1.1. The length direction of the main support 1.1 is perpendicular to the length direction of the secondary support 1.2. The secondary support 1.2 includes a third support 1.2.1 and a fourth support 1.2.2, and the arrangement of the third support 1.2.1 and the fourth support 1.2.2 is similar to the arrangement of the first support 1.1.1 and the second support 1.1.2. Specifically, the third support 1.2.1 and the fourth support 1.2.2 are both C-shaped channel steel structures. Each set of secondary supports 1.2 includes one third support 1.2.1 and two fourth supports 1.2.2, and the two sets of fourth supports 1.2.2 are arranged at both ends of the third support 1.2.1. A second adjustment groove 7 is provided on the third bracket 1.2.1, located close to the fourth bracket 1.2.2. The second adjustment groove 7 is oblong in shape. A corresponding connecting hole is provided on the fourth bracket 1.2.2. By connecting the connecting hole on the fourth bracket 1.2.2 and the second adjustment groove 7 on the third bracket 1.2.1 with bolts or other fasteners, the third bracket 1.2.1 and the fourth bracket 1.2.2 can be fixed together. Alternatively, the positions of the second adjustment groove 7 and the connecting hole can be interchanged. That is, the second adjustment groove 7 is provided on the fourth bracket 1.2.2, located close to the third bracket 1.2.1, and is oblong in shape. A corresponding connecting hole is provided on the third bracket 1.2.1. By connecting the connecting hole on the third bracket 1.2.1 and the second adjustment groove 7 on the fourth bracket 1.2.2 with bolts or other fasteners, the third bracket 1.2.1 and the fourth bracket 1.2.2 can be fixed together.

[0033] The C-shaped slots of the third bracket 1.2.1 and the fourth bracket 1.2.2 are arranged facing downwards, with the bottom of the slots facing down. The C-shaped cross-sectional dimension of the third bracket 1.2.1 is larger than that of the fourth bracket 1.2.2, meaning that the fourth bracket 1.2.2 can be inserted into the C-shaped slot of the third bracket 1.2.1 to achieve a sliding and adjustable connection. The third bracket 1.2.1 and the second bracket 1.1.2 are fixedly connected by bolts. Since the second bracket 1.1.2 can be adjusted relative to the first bracket 1.1.1 in a first direction, and the fourth bracket 1.2.2 can be adjusted relative to the third bracket 1.2.1 in a second direction, and a connecting rope 3 is suspended on the fourth bracket 1.2.2, the position of the connecting rope 3 can be adjusted by adjusting the second bracket 1.1.2 and the fourth bracket 1.2.2, thus enabling the arrangement of elevator shaft template frames of different sizes. In this design, one side of the second bracket 1.1.2 faces upwards, while the bottom of the groove of the third bracket 1.2.1 faces downwards, forming a connecting plane with the side of the second bracket 1.1.2. This provides a flat surface for the installation of the third bracket 1.2.1, ensuring its stability. Furthermore, the fourth brackets at both ends of the third bracket can be completely retracted into it, facilitating the handling and transfer of the template frame.

[0034] A connecting rope 3 is provided between the fourth support 1.2.2 and the pit support 2. The connecting rope 3 is a steel wire rope structure. In this embodiment, the upper end of the connecting rope 3 is fixedly connected to the fourth support 1.2.2, and the lower end of the connecting rope 3 is adjustablely connected to the pit support 2. Specifically, a through hole is provided at the end of the fourth support 1.2.2 away from the third support 1.2.1. The upper end of the connecting rope 3 passes through the through hole and is tightened to the body of the connecting rope 3 by locking buckles 8. Three sets of locking buckles 8 are provided. A tensioning component 9 is provided on the pit support 2. One end of the tensioning component 9 is fixed to the pit support 2, and the other end of the tensioning component 9 is fixedly connected to the lower end of the connecting rope 3. After the connecting rope 3 is arranged, the connecting rope 3 should be arranged vertically, and the four sets of connecting ropes 3 should also be parallel, that is, forming a constraint space for the elevator shaft.

[0035] Furthermore, the tensioning assembly 9 includes an adjusting component 9.1, a connecting component 9.2 (OO type turnbuckle), and an elastic component 9.3, arranged from top to bottom as connecting component 9.2, elastic component 9.3, and adjusting component 9.1. The adjusting component 9.1 is adjustablely connected to the pit support 2. The adjusting component 9.2 is a ring bolt. The pit support 2 is a Z-shaped support, which includes a first connecting surface 2.1 and a second connecting surface 2.2. The position of the first connecting surface 2.1 is lower than that of the second connecting surface 2.2. The first connecting surface 2.1 is fixedly connected to the pit by bolts. The second connecting surface 2.2 is adjustablely connected to the threaded section of the adjusting component 9.1 with a nut. By loosening the nut, the position of the adjusting component 9.1 on the second connecting surface 2.2 can be changed, ensuring that the connecting rope 3 is vertical. The top of the ring bolt (adjusting component 9.1) is a circular connecting hole. The elastic component 9.3 is a tension spring structure, with hooks at both ends, which connect to the connecting holes of the ring bolt and the connecting holes on the connecting component 9.2, respectively. The connecting component includes a tapered sleeve 9.2.1, two connecting rods 9.2.2, and an oblong connecting ring 9.2.3. Threaded holes are provided at both ends of the length of the connecting ring 9.2.3. One end of one set of connecting rods 9.2.2 is threadedly fixedly connected to one end of the connecting ring 9.2.3, and the other end of the connecting rod 9.2.2 is fixedly connected to the bottom of the tapered sleeve 9.2.1. The interior of the tapered sleeve 9.2.1 is fixedly connected to the lower end of the connecting rope 3. The threaded hole at the other end of the connecting ring 9.2.3 is threadedly fixedly connected to another set of connecting rods 9.2.2, and the end of the connecting rod 9.2.2 away from the connecting ring 9.2.3 has a circular connecting hole that connects to the hook of the elastic component 9.3.

[0036] When it is necessary to adjust the tension of the connecting rope 3, simply rotate the connecting ring 9.2.3, causing the connecting rods 9.2.2 at both ends of the connecting ring 9.2.3 to simultaneously extend and retract, thereby tightening or loosening the elastic element 9.3 and the connecting rope 3 to meet the required tension. The elastic element 9.3 acts as a buffer during tension adjustment of the connecting rope 3 and also balances the tension adjustment, preventing the connecting rope 3 from becoming excessively taut.

[0037] The pit support 2 includes a first connecting surface 2.1 and a second connecting surface 2.2. The first connecting surface 2.1 has a first connecting groove 2.1.1, and the second connecting surface 2.2 has a second connecting groove 2.2.1. Both the first and second connecting grooves 2.1.1 and 2.2.1 are oblong structures, and their length directions are perpendicular to each other. The first connecting groove 2.1.1 is fixedly connected to the pit by bolts, while the second connecting groove 2.2.1 is connected to an adjusting member 9.1. Because the first and second connecting grooves 2.1.1 and 2.2.1 are perpendicular to each other, the position of the adjusting member 9.1 in both the length and width directions can be adjusted, changing the fixing point at the bottom of the connecting rope 3 and adjusting the connection position of the connecting rope 3.

[0038] A card 10 is also provided on the connecting rope 3. The card 10 can be used to record the distance between the finished surface and the connecting rope 3, which is convenient for decoration construction workers to check and verify. The card 10 can be fixed to the connecting rope 3 with cable ties, so that the position of the card 10 can be adjusted.

[0039] An installation method for an elevator shaft template frame, wherein the above-mentioned elevator shaft template frame is used for installation, and the installation steps of the template frame are as follows.

[0040] First, assemble the main support 1.1 and the secondary support 1.2: Based on the shaft depth, precisely adjust the position of the second support 1.1.2 relative to the first support 1.1.1 and then fix it, ensuring that the first support 1.1.1 and the second support 1.1.2 are installed stably and their positions conform to the civil engineering dimensions. Then, place the two sets of third supports 1.2.1 stably on the second support 1.1.2 and the fixing frame respectively, using locating pins or bolts for positioning and connection, ensuring the diagonal of the third support 1.2.1 is accurate. Next, use bolt assemblies to connect and fix the third support 1.2.1 to the second support 1.1.2, ensuring the bolts are tightened evenly to avoid loosening or uneven stress. Finally, based on the elevator shaft width, use bolt assemblies to fix the fourth support 1.2.2 at both ends of the third support 1.2.1, ensuring the fourth support 1.2.2 is horizontal to the third support 1.2.1.

[0041] Next, install the connecting rope 3: thread one end of the connecting rope 3 through the reserved through hole on the fourth bracket 1.2.2, slowly lower it to the pit to a suitable length, and then use three rope clips (locking fasteners 8) to fix the other end to the fourth bracket 1.2.2. After fixing, check whether the connecting rope 3 is secure and whether there are any signs of loosening.

[0042] Next, fix the template frame: use four expansion bolts to firmly fix the assembled template frame (main support 1.1 and secondary support 1.2) to the top floor slab surface 5. Before drilling, it is necessary to confirm that there are no obstacles such as underfloor heating in the floor slab. The drilling depth and diameter should match the specifications of the expansion bolts. After installation, it is necessary to check whether the template frame is level and whether there is any shaking.
