The fixing positions of the two first clamping members 22 with respect to the first elongated body 21 and the fixing positions of the two second clamping members 32 with respect to the second elongated body 31 can be adjusted by a user according to the size of the elevator shaft to determine the size of the base 10, so that the construction equipment 1 including the base 10 can be applied to various construction projects without additional fabrication. In addition, the transportation of the construction equipment 1 is also facilitated by the detachable nature of the base 10.

In some embodiments, as shown in fig. 1 and 2, the base 10 further comprises a plurality of trusses 40. Truss 40 is configured for increasing the stability of platform 50. In some embodiments, the plurality of trusses 40 are parallel to and between the two transverse members 305 and span the two longitudinal members 20. The trusses 40 may each be C-channel irons and are secured to the two longitudinal members 20 by suitable means, such as screw locking. It will be appreciated that truss 40 may be omitted when platform 50 is positioned over the endless frame formed by the two longitudinal members 20 and the two transverse members 30, provided that platform 50 is sufficiently smooth for an applicator worker to safely stand on. In some embodiments, the truss 40 has a telescopic structure similar to the longitudinal member 20 of fig. 2, so that the length can be adjusted according to actual requirements. In other embodiments, the two transverse assemblies 30 are omitted and the two longitudinal assemblies 20 are connected only via the plurality of trusses 40.

In some embodiments, the base 10 further comprises a plurality of hooks 15 as shown in fig. 1. The hook 15 is configured for connection of a cable 80 (see fig. 5A) attached to a hanging apparatus, such as a crane (not shown).

In other embodiments, the hooks 15 are omitted, wherein the holes for hanging the cables are formed on the two longitudinal members 20 and/or the two transverse members 30 of the base 10 during the molding process to connect with the hanging device.

In some embodiments, a plurality of support units 60 are disposed respectively below four corners of the base 10 and configured such that the base 10 can be stably disposed in the elevator shaft. In one embodiment, the support units 60 are fixed to both ends of each of the two longitudinal members 20. The structure of the supporting unit 60 according to an embodiment of the present invention is described as follows:

referring to fig. 4, a partial enlarged view of the area 4 of fig. 1 according to the present invention is shown. In some embodiments, the supporting units 60 each include a bracket 61, a fixing member 62, a limiting member 63, and a rotating shaft 64. The bracket 61 is fixed to the end of one of the two longitudinal members 20. In this embodiment, the bracket 61 comprises two parallel plates fixed to the inner and outer opposite sides of the first clamping member 22 of the longitudinal member 20. The fixed member 62 is connected to the lower end of the bracket 61 away from the base 10 via a rotating shaft 64 and can rotate freely around the rotating shaft 64. The limiting member 63 protrudes outward from the bracket 61 and is located above the rotating shaft 64, and is configured to limit the rotation of the fixing member 62.

As shown in fig. 4, the fixing member 62 includes a supporting portion 621, an intermediate portion 622, and a weight portion 623. The abutting portion 621 meets the middle portion 622 at the rotating shaft 64 and extends along an extending direction L (shown in fig. 2) perpendicular to the rotating shaft 64, wherein the abutting portion 621 extends outward beyond the periphery of the base 10. Specifically, as shown in fig. 4, the abutting portion 621 extends beyond the periphery of the base 10 defined by the end of the first clamping element 22, and the end of the abutting portion 621 is farther away from the bracket 61 than the end of the limiting member 63. In some embodiments, the abutting portion 621 has an upper edge 624 abutting against the limiting member 63 when the fixing member 62 is in the closed position (as shown in fig. 4). A chamfer 625 is formed between the end of the upper edge 624 and the end of the abutting portion 621 (the end far from the rotating shaft 64). The function of the chamfer 625 will be further described in the embodiments of fig. 5A to 5F.

The intermediate portion 622 extends from the rotation shaft 64 in a direction opposite to the abutting portion 621. The extension length of the middle portion 622 may be smaller than the extension length of the holding portion 621. The weight portion 623 is connected to a side of the intermediate portion 622 opposite to the holding portion 621. As shown in fig. 4, the weight portion 623 extends obliquely downward from the intermediate portion 622, wherein the extending direction L of the abutting portion 621 and the intermediate portion 622 forms a predetermined angle a with the extending direction of the weight portion 623, and the predetermined angle a is between 120 degrees and 150 degrees from the extending direction L to the weight portion 623 in the clockwise direction. In one embodiment, the extension length of the middle portion 622 and the predetermined angle a are designed and selected so that the fixing member 62 can move from the open position back to the closed position by the gravity provided by the weight portion 623. The operation of the fixing member 62 will be further described in the following embodiments of fig. 5A to 5F.

In one embodiment, the fixing member 62 has a C-shaped cross section, and the abutting portion 621, the middle portion 622 and the weight portion 623 are integrally formed. Since the abutting portion 621, the intermediate portion 622, and the weight portion 623 each have the same specific gravity, the weight portion 623 is disposed so as to be inclined downward with respect to the intermediate portion 622, whereby the fixing member 62 can be moved upward from the open position to the closed position by the gravity of the weight portion 623 while reducing the length of extension of the weight portion 623 toward the inside of the base 10.

Referring to fig. 5A to 5F, elevator shaft construction systems using the elevator shaft construction apparatus 1 according to some embodiments of the present invention are shown. The operation of the system is described as follows:

as shown in fig. 5A, the method of constructing an elevator shaft comprises placing the shaft construction device 1 in a shaft wall 70 having a first construction state. The first construction state is a state in which a building under construction is constructed to a first floor without being completed. In some embodiments, the hoistway wall 70 of the first construction condition includes a plurality of recessed holes 71 that open at a first height H1 relative to the support structure 60. The recess 71 has a flat lower surface 72 and an upwardly inclined upper surface 73. The hoistway construction equipment 1 is moved upward and downward along the hoistway wall 70 by means of a suspension device (not shown) such as a crane via a rope 80. When the fixing element 62 of the supporting structure 60 moves to the recess 71, the abutting portion 621 of the fixing element 62 extends into the first recess 71, so that the fixing element 62 of the supporting structure 60 is located at the closed position as shown in fig. 5A. In this closed position, the abutment 621 of the fixing member 62 is substantially parallel to the horizontal direction, and the lower edge 626 and the upper edge 624 thereof simultaneously abut against the lower surface 72 of the recessed hole 71 and the stop 63 of the support structure 60, thereby maintaining the elevator shaft construction equipment 1 at the first height H1.

As shown in fig. 5B, the method of constructing the elevator hoistway further comprises allowing a construction worker to stand above the platform 50 of the hoistway construction equipment 1 to construct the elevator hoistway with the fixtures 62 of the support structure 60 in the closed position, thereby constructing the hoistway wall 70' having the second construction state. The second construction state is a state in which the building under construction is constructed to the second floor. The second intermediate floor is located above the first floor. In some embodiments, as shown in fig. 5B, the hoistway wall 70' in the second construction state includes a plurality of recessed holes 71 corresponding to the openings of the support structure 60 at the second height H2.

As shown in fig. 5C, the method of constructing the elevator hoistway further includes moving the hoistway construction equipment 1 upward along the hoistway wall 70' via a cable 80 using a suspension device (not shown) such as a crane. At this time, the upper edge 624 of the fixing element 62 of the supporting structure 60 abuts against the inclined upper surface 73 in the concave hole 71, so that the fixing element 62 of the supporting structure 60 rotates from the closed position to the open position, and the abutting portion 621 of the fixing element 62 moves toward the outside of the concave hole 71. The aforementioned open position is an unspecified position with respect to the closed position. At the open position, the supporting portion 621 of the fixing element 62 leaves the limiting element 63 and forms an included angle with the horizontal direction. In some embodiments, since the end of the upper edge 624 of the fixing member 62 is formed with the chamfer 625, the wear of the fixing member 62 due to friction with the upper surface of the recess 71 can be reduced, thereby increasing the life of the fixing member 62.

Next, as shown in fig. 5D, as the height of the elevator shaft construction device 1 is raised, the abutting portion 621 of the fixing member 62 finally leaves the recessed hole 71 at the first height H1 and abuts against the inner wall surface 75 of the elevator shaft wall 70'. Next, as shown in fig. 5E, when the height of the elevator shaft construction equipment 1 is raised to a position slightly higher than the second height H2 of the recessed hole 71, the abutting portion 621 of the fixing element 62 is no longer abutted by the inner wall surface 75 of the elevator shaft wall 70', and the fixing element 62 automatically rotates from the open position to the closed position due to the gravity of the counterweight portion 623, so that the abutting portion 621 of the fixing element 62 extends into the recessed hole 71 at the second height H2.

As shown in fig. 5F, the method of constructing an elevator hoistway further includes moving the hoistway construction equipment 1 slightly downward via the cable 80 using a suspension device (not shown) such as a crane, and moving the abutment 621 of the fixing member 62 into the closed position again. In this closed position, the abutting portion 621 of the fixing member 62 is substantially parallel to the horizontal direction and abuts against the lower surface 72 of the recessed hole 71 and the stopper 63 at the same time, thereby maintaining the second height H2 of the elevator shaft construction equipment 1 on the elevator shaft wall 70'. The above steps of fig. 5B to 5F are then repeated until the elevator shaft is constructed to a predetermined height.

Fig. 6 shows a schematic view of an elevator shaft construction apparatus 1a according to an embodiment of the present invention. In this embodiment, the same elements as those of the elevator shaft construction apparatus 1 of fig. 1 to 5 will be assigned the same reference numerals, and the features of the elements will not be described repeatedly. According to the utility model discloses an embodiment, elevator shaft construction equipment 1a contains with elevator shaft construction equipment 1's difference: the fixture supporting unit 60 of the elevator hoistway construction equipment 1 is replaced with a supporting unit 60 a.

As shown in fig. 7, the difference between the supporting unit 60a and the supporting unit 60 includes: the fixing member 62 is replaced with a fixing member 62a, and a torsion spring 65 is additionally provided. In this embodiment, the fixing element 62a includes a supporting portion 621a and an extending portion 622a. The structure characteristics of the supporting portion 621a and the extending portion 622a can be similar to those of the supporting portion 621 and the extending portion 622 of fig. 4. The torsion spring 65 is disposed around the rotation shaft 64 and configured to provide a restoring force for rotating the fixing member 62 from the open position to the closed position.

The utility model discloses an elevartor shaft construction equipment 1's technical advantage contains: (1) Since the supporting portion 621 of the fixing member 62 is stably erected in the concave hole 71, and the rotation of the fixing member 62 is limited by the limiting member 63, the elevator hoistway construction equipment 1 can be stably erected at a specific height in the elevator hoistway (according to the experimental result, the sum of the payload and the live load of the elevator hoistway construction equipment 1 can be up to 400 kg/square meter); (2) Since the platform 50 is stably supported by the base 10, even though the constructor moves to the edge of the platform 50, it can stably stand on the platform 50; (3) After the construction of the elevator shaft is completed, since the elevator shaft construction apparatus 1 can be removed from the upper opening of the elevator shaft, the elevator shaft construction apparatus 1 can be moved to another construction site for continued use, thereby reducing the construction cost; (4) Via the base assembly of telescopic length, the minimum distance of the periphery of the elevator shaft construction equipment 1 from the inner wall surface of the elevator shaft can be reduced to less than 20 cm.

The above-mentioned embodiments are only for illustrating the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, and the equivalent changes or modifications made according to the spirit of the present invention should be covered within the scope of the present invention, when it is not used to limit the scope of the present invention.
