Description

  The present invention relates to an elevator guide rail erection method related to the installation of a guide rail to an elevator hoistway installed in a building (house).

Conventionally, when a guide rail is erected on an elevator hoistway , after the lowermost rail is erected, 2-5 rails of a predetermined unit length are connected in the tower or pit of the hoistway and then the lowermost rail is The rails are placed on the upper end of the rails and connected to each other with a rail joint plate, and these steps are repeated in sequence as many times as necessary to reach the top floor, and the rails for the entire height are erected. At this time, as the centering fixing of the rail positioning, a method is adopted in which the upper rail is placed on the lower rail and then the position of the upper rail is adjusted and then fixed by the rail joint plate.

  However, according to such a method for adjusting the position of the rail, the load on the upper rail is applied to the lower rail, and the upper rail and the lower rail of the lower rail after being connected and fixed may be curved. Further, the building contracts by about 10 to 20 mm per 100 m of the building height due to an increase in the weight of the building under construction or a secular change after the building is used. The compression force due to such contraction may act on the rail, and the entire rail may be bent similarly. In such a case, if there is no gap between the rails, it becomes impossible to correct the curvature of the rails.

  The problem here will be described in detail by specifically illustrating the connection and fixing of the rail. First, lift the bottom rail to a predetermined position with a lifting machine such as a winch, position it according to a preset piano wire as a reference, center it, and then firmly fix it with rail clip bolts To do. Next, the third-stage rail, which is also temporarily placed on the upper end of the second-stage rail temporarily placed in the pit, is lifted by a lifting machine and connected to each other with bolts using a rail joint plate. After that, similarly, the fourth-stage rail is put on the upper end portion of the third-stage rail and connected to assemble a one-line rail connecting the three rails. Next, the assembled single rail is lifted with a lifting machine and placed on the upper end of the lowest rail that was positioned first, and the uppermost part of the fourth rail is temporarily fixed with rail clip bolts, and then the lifting machine hook After removing the, and centering the single rail to the piano wire, tighten the rail clip bolt of each step and fix. After that, the assembly of the 5th to 7th rails as a single rail is placed on the upper end of the 4th rail and repeated until it reaches the total height required by the same procedure. Stand up.

  According to such a rail connection and fixing method, the load of the rail for the third stage is applied on the lowermost rail, and the load of the rail at the upper position is also applied to the second and third rails. Moreover, since the single rail of the same structure is repeatedly connected, the load applied to the rail of a downward position will become large, so that the total height of a rail is high. As a result, the entire rail after being connected to one line is curved. When the rail is centered, it cannot be centered unless the rail side is struck with a heavy hammer. May remain uncorrected. Even if such curvature is corrected and fixed, if the building progresses or the building contracts due to secular change, the rail may be bent by the compressive force at that time. The curvature generated in the rail becomes a big problem for the elevator even if the amount of compression of the rail is small.

  FIG. 8 is a correlation diagram of the amount of bending and bending of the curved rail shown in contrast to the vertical rail in order to explain the relationship between the compressive force applied to the known rail and the degree of bending (although it is not an invention related to the literature). , A generally known technique). In FIG. 8, when the rail of the length L is compressed by Δx by receiving the compression force F due to the load by the rail at the upper position or the contraction by the weight of the building (building) when standing the rail, the upper end position P of the vertical rail is On the other hand, in the curved rail, the upper end position P ′ is displaced vertically downward, and a curve corresponding to the maximum dimension H is generated in the lateral direction M including the 0 ′ curved middle point of the curved rail with respect to the zero middle point of the vertical rail. It shows a state. Incidentally, in FIG. 8, the dimension from the upper end position P of the vertical rail to the upper end position P ′ of the curved rail in the vertical direction is the compression amount Δx, and the dimension from the upper end position P ′ of the curved rail to the 0 ′ curved middle point of the curved rail. Is (L−Δx) / 2, the dimension from 0 midpoint of the vertical rail to 0 ′ curved midpoint of the curved rail is Δx / 2, and the dimension from the upper end position P ′ of the curved rail to 0 midpoint of the vertical rail is (L / 2) −Δx, and the dimension from the upper end position P of the vertical rail to the 0 midpoint of the vertical rail is indicated by L / 2. According to the calculation, when a standard rail having a basic unit length of 5 m is compressed by a compression force F by a compression amount Δx = 1 mm, a curve with a maximum dimension H = 50 mm is generated in the lateral direction M, and a compression amount Δx = 0.1 mm is compressed. Then, a curvature with the maximum dimension H = 15.8 mm is generated. Since the guide rail of an elevator needs to be installed with high accuracy within an allowable range of curvature of 2 mm or less, if a large curvature occurs, it will be fatal damage.

  Thus, as a well-known technique for preventing such a guide rail from being bent, there is an “elevator rail” (see Patent Document 1) in which a joint portion is expanded and contracted in accordance with the expansion and contraction of a building.

JP-A-62-218384

  In the technique of Patent Document 1 described above, a projection and a tenon are provided at the end of one rail in the joint portion, a notch and a tenon are provided at the end of the other rail, and the two are fitted together. By inserting the back surface of the other rail into the groove portion of the grooved plate fixed to the back surface of the rail, the other rail with respect to one rail can be moved in the longitudinal direction at the joint portion. If it is a simple structure, special precision processing is required when manufacturing both ends of the rail and rail joint plate (grooved plate), which requires complicated and expensive parts processing, which makes it very expensive. In addition, there is a problem that it is not practical because the special precision machined part is easily deformed (curved) during handling in the field, and therefore requires careful handling.

  The present invention has been made to solve such problems, and its technical problem is that a load applied to the lower rail when the guide rail is erected without requiring complicated and expensive parts processing. It is to provide an elevator guide rail standing method that can prevent the occurrence of bending and suppress the occurrence of bending as much as possible.

In order to solve the above technical problem, the present invention relates to an elevator guide rail standing method for standing a guide rail in an elevator hoistway installed in a building. When connecting using rails, a thin plate is inserted into each connecting portion of the rails, and then fastened to the connecting plate with bolts to firmly connect the rails. Tension is applied to remove the influence of the weight underneath and the rail clip is fastened to the rail clip attached to the rail bracket provided at a predetermined position between the floors of the hoistway wall with the rail clip bolt. after fixing to the wall, on the assumption that the rails be provided with a small gap in the connection portion between the rail pulling the thin plate, respectively, further When connecting a plurality of rails of a predetermined unit length in a tower of a hoistway or in a pit using a connecting plate, a thin plate is inserted into each connecting portion between the rails and then fastened to the connecting plate with a bolt. The rail connection step for firmly connecting the rails to each other, and the rail connected by the rail connection step is vertically installed on the wall surface of the hoistway, and a lifting tension is applied upward in the vertical direction by the suspension lifting means. After removing the influence of the weight under the center and positioning by centering, it is fastened with rail clip bolts to the rail clip attached to the rail bracket provided at a predetermined position between the floors of the hoistway wall After fixing to the wall of the hoistway, pull out the thin plate and attach the rail so that a minute gap is provided at the connection part between the rails. And having cormorants rail mounting step.

Hereinafter, an elevator guide rail standing method according to the present invention will be described in detail with reference to the drawings. First, a technical outline of the elevator guide rail erection method of the present invention will be briefly described. This is applied when the guide rails are erected in the elevator hoistway installed in the building. When connecting multiple unit-length rails using a connecting plate, a thin plate is inserted into each connecting portion between the rails and then fastened to the connecting plate with bolts to firmly connect the rails to each other. With a rail clip bolt attached to a rail clip attached to a rail bracket provided at a predetermined position between each floor of the hoistway wall by applying a pulling tension upward in the vertical direction to remove the influence of the weight underneath And after fixing to the wall surface of a hoistway, it presupposes that a thin board is each pulled out and a micro clearance gap is provided in the connection part of rails . Speaking concrete, upon coupling with the connecting plate a plurality of rails having a predetermined unit length in the tower or in the pit of the hoistway, bolt connecting plate from each insert a thin plate connection portion between the rail The rail connection step for firmly connecting the rails by fastening the rails, and the rail connected by the rail connection step is vertically installed on the wall of the hoistway, and the tension is pulled upward in the vertical direction by the suspension lifting means. After removing the influence of its own weight and positioning by centering, it is fastened with a rail clip bolt to a rail clip attached to a rail bracket provided at a predetermined position between each floor of the hoistway wall After fixing the rails to the wall of the hoistway, the rails are attached by pulling out the thin plates and providing a small gap at the connection between the rails. Basic to have a mounting step.

  However, the rail installation step here is, from the viewpoint of work procedure, standing the bottom rail in the vertical direction on the wall of the hoistway and positioning it by centering, and then fastening it with rail clip bolts. After fixing to the wall surface, place the rail connected with a thin plate on the upper end of the lowermost rail and fasten it to the connecting plate with bolts to firmly connect the rails, and suspend the connected rails A fixing step of applying a lifting tension upward in the vertical direction by the lifting means to remove the influence of the upper position rail weight and positioning by centering, and then fastening the rail clip bolt and fixing it to the wall of the hoistway, Including an initial rail mounting step.

  Further, in this rail mounting step, in the viewpoint of the subsequent work procedure, the rails connected to each other with a thin plate interposed between the upper ends of the connected rails are fastened with bolts to the connecting plates. The connection continuation step in which the above-mentioned connection step is continued by firmly connecting the rails, and the separate rails connected to each other are lifted upward in the vertical direction by the lifting and lifting means to remove the influence of the weight of the upper position rail. Then, after performing positioning by centering, fastening the rail clip bolt and fixing it to the wall surface of the hoistway, the fixing continuation step that continues the fixing step, the number of times required to reach the top floor, The rail standing continuation step, where the rail for the entire height is erected repeatedly in sequence, and the thin plate is pulled out sequentially after the rail for the entire height is erected And the thin withdrawal providing a small gap in the connection portion of the Judges, is intended to include. As the thin plate, it is preferable to use a thin plate having a thickness of 1 to 2 mm and a vertical and horizontal dimension of several cm square.

  According to such an elevator guide rail standing method, the load applied to the lower rail when the guide rail is standing is prevented without requiring complicated and expensive parts processing as in the technique of Patent Document 1. In addition, the occurrence of bending can be suppressed as much as possible, and a minute gap exists in the connection part between the rails, so even if the bending occurs after the rail is erected, the bending is corrected and easily removed can do. Below, the Example according to the operation | movement procedure of the guide rail standing method for elevators mentioned above is given, and it demonstrates concretely.

  FIG. 1 is a schematic diagram showing a specific work procedure of the elevator guide rail standing method according to the first embodiment of the present invention in stages. In this work procedure, first, in the first stage, the bottom rail is attached to the wall of the hoistway and centering is fixed, and in the second stage, the second and subsequent rails in the elevator tower or pit. Are connected in units of two to three. However, at this time, a thin steel plate having a thickness of 1 to 2 mm is inserted into each connection portion between the rails to perform connection. In order to connect the rails to each other, a connecting rail is used, and the ends of the rails connected to the same connecting plate are fastened with bolts to firmly connect the rails to form a continuous rail (connecting rail). . Subsequently, in the third stage, the continuous rail produced in the previous section is lifted to the upper part of the lowermost rail with a lifting machine, and in the fourth stage, the continuous rail in the previous section is pulled with a towing tool, and the lowermost rail is connected. It hangs down to the position and inserts a thin steel plate into the connection.

  Further, in the fifth stage, the traction tool is further lowered, and when the continuous rail as the upper rail comes into contact with the thin steel plate, the drooping is stopped, and the two are tightly connected by the connecting plate bolt. However, in the sixth stage, if the continuous rail that is the upper rail is left on the lowermost rail that is the lower rail, the entire rail may be bent by the weight of the upper rail. Therefore, in the next seventh stage, in order to remove the bend, the entire rail is finely pulled upward by the connected traction tool, the pulling tension is applied to the entire rail, and the own weight applied to the lower rail is removed. In this state, in the eighth stage, the rail is centered at the normal position at the uppermost rail bracket portion of the continuous rail, which is the upper rail, and fixed with the bracket bolts. Further, in the ninth stage, the positional deviation of the middle portion of the continuous rail which is the upper side rail is confirmed, and the bolts of the bracket are sequentially fixed from the upper side.

  In the subsequent tenth stage, after fixing, the lifting machine is removed from the rail. In the eleventh stage after this, the second term of the second stage to the eighth term of the eighth stage are repeated for the upper rails (continuous rails) necessary for the floors of all floors, Set up a rail for minutes. In the final twelfth stage, after all the rails are erected and centered and fixed, the thin steel plates inserted into the connecting portions of the respective tiers are pulled out to complete the rail erection operation.

  FIG. 2 is a partially enlarged view showing the state of rail lifting performed in the work procedure of the elevator guide rail standing method described above from the front side. In FIG. 2, first, a positioning piano wire (not shown) for installing guide rails is installed in the tower 3 of the elevator hoistway, and the lowest rail (in the pit 2 of the lowest floor 1) First stage rail) 7 is lifted up to a predetermined position by a lifting machine 12 such as a winch, positioned in accordance with the piano wire and centered on the lowermost rail 7, and then between each floor 1 on the wall of the hoistway The rail clip 5 attached to the rail bracket 4 provided at the predetermined position is fastened (fastened) with the rail clip bolt 6 to be firmly fixed. In FIG. 2, after the lowermost rail (first rail) 7 is attached to the regular position on the wall of the hoistway, the second rail 8, the third rail 9, 2 in the elevator tower 3 or pit 2, For the continuous rail (connection rail) that is firmly connected to the connection plate 11 by fastening the fourth-stage rail 10 with bolts, the chain block or the like is pulled to the wire attached to the bolt hole of the uppermost connection plate 11. A state is shown in which the continuous rail is lifted or suspended in the vertical direction while the hook 14 of the tool 13 is hooked. At this time, the traction tool 13 such as a chain block is attached to the wire of the lifting machine 12. That is, the lifting machine 12 including the wire here and the traction tool 13 including the hook 14 function as suspension lifting means that suspends and lifts the continuous rail together. In this embodiment, a chain block is used as the traction tool 13, and not only adjustment by traction in the height direction by the lifting machine 12 but also fine adjustment in the height direction by the traction tool 13 is possible.

  FIG. 3 is an enlarged view of a main part showing a rail connection state in the continuous rail shown in FIG. FIG. 3 shows a state in which a thin steel plate 15 having a thickness of 1 mm to 2 mm and a vertical and horizontal dimension of 2 cm to 3 cm is interposed at a connecting portion of the second rail 8 and the third rail 9 in the continuous rail. Of course, the same thin steel plate 15 is also interposed in connection portions between other rails (for example, connection portions of the third-stage rail 9 and the fourth-stage rail 10 (not shown) and other connection portions). By the way, the thickness of the thin steel plate 15 is a range selected as a gap between the rails, and even if it is too large, it will cause a shake when the elevator (car) travels. In order to make the elevator (car) less comfortable to ride, and to adversely affect the guide shoes and guide rollers guided by the rails, it is preferable to be about 2 mm or less. It is preferable to secure about 1 mm or more because it cannot be sufficiently absorbed (cannot escape). The size of the vertical and horizontal dimensions of the thin steel plate 15 may be determined in consideration of ease of handling and mechanical strength.

  FIG. 4 is a diagram showing a case where no bending occurs as a form of a rail connection state implemented in the work procedure of the elevator guide rail standing method described above from the front direction. In FIG. 4, a continuous rail (second rail 8, third rail 9, and fourth rail 10) that is a single rail is lifted by a lifting machine 12 via a traction tool 13, and then the bottom rail. 7 is hung down to a position of several centimeters to several tens of centimeters above 7, and is then hung slowly by the traction tool 13 until it reaches the connection position. And when it becomes a connection position, after inserting the thin steel plate 15 in a connection part in order to secure a clearance gap, it shows a mode that the end of the rail connected to the same connection board 11 is firmly fastened with a bolt, and rails are connected. ing.

  FIG. 5 is a diagram showing a case where a curve is generated from the front direction as one form of a rail connection state implemented in the work procedure of the elevator guide rail standing method described above. In FIG. 5, when connecting the rails using the connecting plate 11 with the thin steel plate 15 interposed in the lowermost rail 4 of the continuous rail described in FIG. 4, the continuous rail is suspended. If the state is left as it is, a curve may occur due to the load on the upper rail, and the situation in such a case is shown. In particular, in FIG. 5, the load due to the fourth-stage rail 10 and the third-stage rail 9 with respect to the second-stage rail 8 is larger (medium) than the load due to the fourth-stage rail 10 with respect to the third-stage rail 9. A state in which the load by the second-stage rail 8 to the fourth-stage rail 10 with respect to the rail 7 is the largest is shown.

  FIG. 6 shows, from the front direction, a state in which bending is prevented by applying a pulling tension to the rail by towing as one form of the rail connection state performed in the work procedure of the elevator guide rail standing method described above. FIG. In FIG. 6, the continuous rails are suspended when the rails are connected to each other using the connecting plate 11 with the thin steel plate 15 interposed in the lowermost rail 8 of the continuous rail described as the single rail described in FIG. 4. The state is shown in which the pulling tension is applied to the continuous rail that has been pulled up by the traction tool 13 without being left as it is, and the influence of the weight of the continuous rail in the upper position is removed. Incidentally, even with a lifting machine 12 that does not include the traction tool 13 as a suspension lifting means, the same effect can be obtained if the continuous rail is slightly moved up.

  FIG. 7 is a view showing the rail connection completion state from the front direction after the work procedure of the elevator guide rail standing method described above is performed. In FIG. 7, after removing the influence of the weight of the upper continuous rail described in FIG. 6 and positioning by centering, each rail of the continuous rail (second-stage rail 8 to fourth-stage rail 10). The state where the rail clip bolt 6 of the rail clip 5 attached to the rail bracket 4 is fastened and fixed to the wall surface of the hoistway is shown. That is, in this case, the lowermost rail 7 of the lower rail and the continuous rail of the upper rail are in a tension state in the state shown in FIG. After the stage rail 10 is fastened to the rail clip 5 with the rail clip bolt 6 and fixed to the wall of the hoistway, the second stage rail 8 and the third stage rail 9 that are in the middle position are also removed from the lower rail clip 5. In the same manner, after finely adjusting the position along the piano wire and centering, the rail clip 5 is fastened by the rail clip bolt 6 and fixed to the wall surface of the hoistway. According to such a procedure, the lowermost rail 7 and the continuous rail are unlikely to be bent, and the rail can be erected easily.

  After this, the hook 14 of the traction tool 13 is removed, a thin steel plate 15 is interposed between the upper ends of the connected rails, a separate continuous rail is placed on the connecting plate 11, and the rails are fastened by bolts. In the same manner, a separate continuous rail is lifted upward in the vertical direction to remove the influence of the weight of the upper rail and perform positioning by centering. Then, the rail clip 5 is attached to the rail clip 5 with the rail clip bolt 6. The work of fastening and fixing to the wall of the hoistway is repeated as many times as necessary until reaching the top floor of the building, and after standing up the rails for the total height, the steel sheet 15 is pulled out sequentially, Provide a minute gap in the connection.

  According to the elevator guide rail standing method according to the first embodiment, when the rails are connected to each other, the thin steel plate 15 is interposed in the connecting portion, and then the connecting plate 11 is fastened by the bolt, and the connecting rail is moved up and down. When standing on the wall of the road or when connecting the upper rail to the lower rail, do not deform by its own weight by applying a pulling tension, or apply a pulling tension to the upper rail to apply a load to the lower rail. Since the steel sheet 15 between the rails is finally pulled out and a minute gap is provided at the connecting portion between the rails, the guide is not required to process complicated and expensive parts. It is possible to prevent the load applied to the rail at the lower position when the rail is erected, and to suppress the occurrence of bending as much as possible. As a result, it is possible to prevent the guide rail from being bent due to the weight of the guide rail and the building compressive force due to the weight of the building, and the load on the upper rail relative to the lower rail, The problem of bending of the guide rail due to the compressive force resulting from the contraction can be solved.

  In the elevator guide rail erecting method according to the first embodiment, the case where the thin steel plate 15 is used as the thin plate interposed between the connecting portions of the rails has been described. However, it is also possible to use a plate material made of another material such as a thin iron plate, as long as it has resistance without being deformed and destroyed.
