In the following detailed description, directional terms, such as "upper", "lower", "inner", "outer", "longitudinal", "lateral", and the like, are used with reference to the orientation depicted in the accompanying drawings. The components of embodiments of the present invention can be positioned in a number of different orientations and the directional terminology is used for purposes of illustration and is in no way limiting.

Fig. 1 shows a frame-type steel structure hoistway front view (first side S1) showing the sides of a space for installing elevator car doors in accordance with the present invention; fig. 2 shows a side view (second side S2) of the elevator hoistway. As shown in fig. 1 and 2, the elevator hoistway has a first side S1 and three second sides S2 for arranging the elevator doors 21. The elevator well includes four stands 1, is connected with crossbeam 2 between two adjacent stands 1, is connected with diagonal brace 3 between two adjacent stands 1. The corner of the pillar 1 is disposed toward the outer side in the circumferential direction of the elevator shaft. The 4 columns 1 form 4 corners of an elevator shaft having a rectangular cross section.

It will be understood that it is only conventional to provide the elevator shaft with a rectangular cross-section and to set the number of columns 1 to 4. The number of the pillars constituting the corners of the elevator shaft may alternatively be set to any number of 3, 5, etc., according to the needs of the elevator arrangement place. The cross section of the elevator shaft is correspondingly formed into a polygon such as a triangle, a pentagon and the like or a shape similar to a circle and the like. The following and the attached figures are only schematically illustrated by way of example of an elevator shaft having a rectangular cross section.

The elevator shaft is fixed to an elevator pit 6 located below it. The elevator shaft is connected with the building body 5 through a corridor 4.

In order to improve the wind resistance and the earthquake resistance of the elevator shaft, the upright posts 1, the cross beams 2 and the inclined support rods 3 which form the frame structure of the elevator shaft are all arranged into a slab-shaped angle steel structure with an L-shaped cross section. The column 1, the beam 2, and the diagonal brace 3 may be optionally set to equal angle steel or unequal angle steel according to the load requirement of the car matching the elevator shaft.

The upright posts 1, the cross beams 2 and the diagonal braces 3 are detachably connected through bolts and the like. The above components are directly stacked and transported to an installation site after being cut, drilled, painted, etc. at a factory, and then directly assembled at the site. Because each part is the angle steel structure of lath formula, consequently stand 1, crossbeam 2 and diagonal brace 3 can pile up the loading with the form of embedding each other, and the installation material accessible of elevator well is less vehicle transportation. Meanwhile, workers do not need to perform secondary welding, cutting and the like on the upright posts 1, the cross beams 2 and the diagonal braces 3 on the installation site, so that paint spraying operation can be omitted, and the installation process of the elevator is accelerated.

In order to avoid crossbeam 2, the diagonal brace 3 of installing on stand 1 to produce the moment of flexure on stand 1 and influence the overall structure intensity of elevator well, the utility model discloses a crossbeam 2, diagonal brace 3 are installed on stand 1 through following form. Specifically, the cross members 2 on the adjacent second side surfaces S2 are arranged at the same vertical height (horizontal height). The diagonal brace 3 is arranged between two vertically adjacent cross beams 2, which are arranged obliquely in the vertical direction. On the second side surface S2 of the elevator shaft, the mutually close ends of two diagonal braces 3 adjacent in the vertical direction are respectively adjacent to one end of the cross beam 2 between the two diagonal braces 3 and fixed on the upright posts 1; on the adjacent second side S2, one end of two diagonal braces 3 adjacent in the transverse direction is closely adjacent to and fixed on the upright 1. According to the above, the diagonal brace 3 shows a wave-shaped configuration at the lateral, vertical height of the elevator hoistway. One end of two vertically adjacent diagonal braces 3 is fixed in an "abutting manner on the cross beam 2 therebetween". Preferably, when a worker installs the elevator derrick according to the preset bolt holes of the vertical column 1, the cross beam 2 and the diagonal brace 3, the shape lines of the two diagonal braces 3 intersect at a first intersection point. The first intersection point is close to the end of the cross beam 2 close to the diagonal strut 3, and the first intersection point coincides with the centroid line of the cross beam 2 or has a small distance, so that the diagonal strut 3 does not form bending moment on the upright 1, which obviously affects the strength of the upright.

Similarly to the arrangement of the diagonal member 3 at the second side S2, referring to fig. 1, the diagonal member 3 is also provided in a wave-like configuration in the vertical direction of the first side S1 where the elevator door 21 is provided. With reference to fig. 1-2, preferably, the ends of the diagonal struts 3 of the first side S1 toward the second side S2 are immediately adjacent to the ends of the corresponding diagonal struts 3 of the second side S2. At this moment, on the transverse direction of elevator well, vertical direction, diagonal brace 3 can not produce obvious moment of flexure to stand 1 yet, and the elevator derrick of constituteing by the angle steel can satisfy anti-wind, antidetonation requirement.

Referring to fig. 1, the first side surface S1 of the elevator shaft may be additionally provided with door columns 1' formed of angle steel at both ends corresponding to the width direction of the elevator doors 21. Of course, if the elevator is a side-opening door type elevator, only one door pillar can be arranged. In the example of fig. 1, at least four uprights 1 and door uprights 1' parallel to each other are now formed on the first side S1. The diagonal brace 3, the cross beam 2, and the pillar 1 on the first side surface S1 corresponding to both sides of the elevator door 21 may be symmetrically disposed. The added door pillar 1' and the original pillars 1 at both ends of the first side surface S1 can support the diagonal brace 3 at the first side surface S1.

In some embodiments shown in fig. 1 and 2, the number of diagonal braces 3 at the first side S1 is greater than the number of diagonal braces 3 at the second side S2. For example, a second side section a2 composed of two diagonal braces 3 is formed on the second side S2. The first side S1 has first side sections a1, a 1' that are at the same vertical height as the second side section a 2. The number of diagonal struts 3 located in the first side section a1 is four times the number of diagonal struts 3 located in the second side section a2 on part of the corresponding first and second side sections a1, a2 (8 for the first side section a1 and 2 for the corresponding second side section a 2); and on the opposite first side section a1 ', the second side section a2 of the other part, the number of the diagonal struts 3 of the first side section a 1' is the same as the number of the diagonal struts 3 of the corresponding second side section a 2.

The angle theta between the diagonal brace 3 and the adjacent cross beam 2 on the first side surface S1 and the second side surface S2 is 20-60 degrees, and preferably 30-55 degrees.

Referring to fig. 3, 4, an enlarged view of area a of fig. 2 is shown from the outside and inside perspective of the elevator hoistway, respectively. On the same vertical position of the angle steel forming the upright post 1, one side of the angle steel is directly connected with two inclined supporting rods 3 and is connected with a cross beam 2 through a gusset plate 20; the other side is directly connected to the other beam 2 (fig. 4). The flat-plate-type gusset plate 20 can solve the problem that the cross beams 2 interfere with each other at the same vertical position and the problem that the two diagonal braces 3 adjacent to the cross beams 2 interfere with the cross beams 2, so that one ends of the cross beams 2 and the diagonal braces 3 are arranged on the same vertical position of the upright 1 more closely, and the bending moment applied to the upright 1 is further reduced. At the moment, only a single diagonal brace 3 is arranged between two adjacent cross beams 2 on the same side face of the elevator shaft, so that the requirements of earthquake resistance and wind resistance can be met.

Referring to fig. 4 in conjunction with fig. 3, in some embodiments, one end of the gusset plate 20 is welded to one side of the column 1, and the other end of the gusset plate 20 is connected to the cross member 2 by a bolt 7. In other embodiments, one end of the gusset 20 may alternatively be welded to one end of the cross member 2, while the other end is connected to the upright 1 by bolts 7.

Referring to fig. 5 and 11, in a preferred embodiment, one end of the gusset 20 abuts an edge of the upright 1. After the gusset plate 20 and the edge of the stud 1 are butted, a space F formed between the arc-shaped edge of the stud 1 and the gusset plate 20 is formed just to serve as a space for accommodating the fillet.

Referring to fig. 6, in a more preferred embodiment, both side surfaces of the column 1 are provided with reinforcing plates 22, 23 capable of clamping the gusset 20. The reinforcing plates 22, 23 may be secured to the column 1 by welding. The reinforcing plates 22 and 23 are arranged to support the gusset plate 20 to prevent it from falling off the column 1. The length of the reinforcing plate 22 (inner reinforcing plate) located inside the elevator shaft is advantageously set to be smaller than the length of the reinforcing plate 23 (outer reinforcing plate) located outside the elevator shaft. The shorter internal reinforcing plate contributes to reducing its space occupation inside the elevator. Longer external reinforcing plates may provide a greater degree of security in the connection of the gusset 20 to the upright 1.

Referring to fig. 4, in some preferred embodiments, after the vertically adjacent diagonal braces 3 are installed on the uprights 1, they abut or even abut the cross member 2 therebetween. The diagonal brace 3 may be cut only in a small portion without cutting the one side to which the cross member 2 is attached. For example, in the embodiment of fig. 4, only the diagonal brace 3 above the transverse beam 2 is cut at one corner. The cutting may be performed in advance in the factory. The cut corners form edges having a length d no greater than 25% of the width of the edge of the original post, preferably no greater than 20% of the rim. The advantage of this arrangement is that the structural strength of the portion of the diagonal strut 3 on the upright 1 is not sacrificed and there is no risk of the diagonal strut 3 being bent at this location.

In some preferred embodiments shown in fig. 7-10, both ends of the diagonal brace 3 are provided with adjustment slots 8 through which the connection bolts 7 pass. The extending direction of the adjustment groove 8 is the same as the extending direction of the diagonal brace 3, and is long-hole shaped. In the case of slight deviations in the installation position of the components, the worker can assemble the elevator shaft by adjusting the position of the connecting bolt 7 in the adjustment groove 8.

Preferably, referring to fig. 9-10, an adjustment block assembly 9 capable of sliding adjustment along the axial direction of the adjustment groove 8 (i.e., the length direction of the adjustment groove 8) may be disposed in the adjustment groove 8. The adjusting block assembly 9 includes a first adjusting block 12, a second adjusting block 13, a moving block 16, and the like. Wherein, the first adjusting block 12 is provided with sliding grooves corresponding to the two sides of the width direction of the adjusting groove 8. The moving block 16 is slidably fixed in the sliding groove of the first adjusting block 12. One side of the moving block 16 faces the side wall of the adjusting groove 8, and the opposite side is provided with a first guide inclined surface 17. The second adjusting block 13 is provided with a second guide slope 18 parallel to the first guide slope 17. The first guide slope 17 is in contact with the second guide slope 18.

The first adjusting block 12 is provided with a first bolt hole 14, and the second adjusting block 13 is provided with a second bolt hole 15 corresponding to the first bolt hole 14. The side wall of the adjusting groove 8 is provided with embedded teeth 11, and the embedded teeth 11 are in a sawtooth shape. An end of the moving block 16 near the side wall of the adjustment groove 8 is provided with an embedded layer 19 made of, for example, brass.

According to the above adjusting block assembly 9, both ends of the diagonal brace 3 are connected with the upright 1 through the adjusting block assembly 9 by means of the connecting bolt 7. The upright post 1 is provided with a third bolt hole corresponding to the first bolt hole 14, and the connecting bolt 7 simultaneously passes through the first bolt hole 14, the second bolt hole 15 and the third bolt hole to connect the diagonal brace 3 with the upright post 1. When the first bolt hole 14 and the second bolt hole 15 are misaligned with the third bolt hole, the adjustment block assembly 9 may be moved into position by sliding the adjustment block assembly 9 so that the first bolt hole 14 and the second bolt hole 15 are aligned with the third bolt hole, which facilitates installation of the attachment bolt 7. When the connecting bolt 7 is tightened, the connecting bolt 7 presses the first adjusting block 12 and the second adjusting block 13. During the pressing process, the first adjusting block 12 and the second adjusting block 13 will move towards each other. During the moving process, under the action of the first guide inclined surface 17 and the second guide inclined surface 18, the moving block 16 moves towards the side wall of the adjusting groove 8, so that the moving block 16 is attached to the side wall of the adjusting groove 8. The adjusting block assembly 9 can thus be fixed in a certain position in the adjusting groove 8, which prevents the adjusting block assembly 9 from moving in the adjusting groove 8 and affecting the stability of the whole elevator shaft. When the moving block 16 is tightly attached to the side wall of the adjusting groove 8, the embedded teeth 11 can be embedded into the embedded layer 19, and the fixing effect of the adjusting block assembly 9 is increased.

Hereinafter, for convenience of description, the pillar 1 near the elevator door 21 is simply referred to as a "third bolt hole", and the pillar 1 far from the elevator door 21 is simply referred to as an "inner pillar 1A". In some preferred embodiments as shown in fig. 5, the gusset 20 is secured to the outer upright 1B, which extends toward the inner upright 1A. The length of the gusset plate 20 should ensure that the beam 2 installed on the gusset plate can be dislocated with the elevator door 21, so that the end parts of the left and right side beams 2 of the elevator shaft effectively avoid the space required after the elevator door 21 is opened, the net size of the left and right sides in the elevator shaft becomes larger, the expansion and the enlargement of the opening size of the elevator door 21 are more facilitated, and the space utilization rate of the elevator shaft is improved.

Referring to fig. 11-12, in some embodiments, a buffer groove 24 is provided on an end surface of the gusset 20 adjacent to the outer column 1B along a vertical length of the gusset 20. A plurality of buffer posts 25 made of an elastic material are sequentially arranged in the buffer groove 24 from top to bottom. A plurality of buffer blocks 26 are partitioned at one end of the buffer column 25 close to the outer column 1B. The buffer block 26 abuts on the end face of the outer column 1B. The number of the buffer blocks 26 is preferably set to 4 to 6, and particularly, the function of dispersing the vibration energy can be well performed. When the worker installs, the gusset 20 is first moved toward the outer column 1B, so that the plurality of buffer blocks 26 on the buffer column 25 are first pressed against the outer column 1B. The plurality of buffer blocks 26 are applied with force so as to be dispersed in different directions and closely attached to the end surface of the outer column 1B. Then, the inner reinforcement plate 22 and the outer reinforcement plate 23 are welded.

According to the above, the design of the buffer columns 25 and the buffer blocks 26 can effectively disperse and buffer the vibration energy transmitted from the outer column 1B, thereby improving the stability of the connection between the gusset 20 and the outer column 1B and reducing the sound generated when the outer column 1B vibrates.

The buffer column 25 is made of rubber materials or the like with better elasticity and wear resistance, the buffer column 25 can have better buffer force, and the buffer column 25 and the buffer block 26 can have longer service life.
