The above-described form for use in elevator hoistway construction will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, a formwork for elevator shaft construction mainly includes a plurality of single bodies, a common elevator shaft 12 is square or rectangular in cross section, and four single bodies are configured for diagonal installation in an elevator shaft 12 area with the same height to form a formwork for supporting the inner wall of the elevator shaft 12.
The monomer includes base plate 7 and bar piece, and base plate 7 is as single body construction, is L shape bending plate, and the edge at base plate 7 is installed to the bar piece, and single border position that indicates in this embodiment is along the lift well 12 circumference on single border, uses the bending line of base plate 7 as the benchmark, and the one end that is perpendicular to bending line and keeps away from the bending line is the border of base plate 7. The extending direction along the bending line is the longitudinal direction of the substrate 7, and the direction perpendicular to the bending line and parallel to the plane of the bending plate is the width direction. The shape of the base plate 7 is adapted to the shape of the inner wall of the elevator shaft 12.
The four single bodies correspond to the four base plates 7, the adjacent single bodies are subjected to butt joint structural design, strip-shaped blocks are arranged on the edges of the corresponding base plates 7, the butt joint structure is divided into concave parts and convex parts, and the concave parts and the convex parts can be in butt joint and splicing. The bar-shaped blocks are fixed to the substrate 7 in advance, and the concave portions and the convex portions may be arranged at the same time at two edge positions of the same substrate 7, or the concave portions may be arranged at one edge and the convex portions may be arranged at the other edge. And establishing a stacking and splicing relationship between adjacent monomers according to the surrounded supporting templates.
The first bar-shaped block 5 corresponding to the concave part is integrally contracted in the edge of the substrate 7, the first bar-shaped block 5 is provided with a first inclined surface 10 and a first bottom surface which are adjacent and distributed at an acute angle, as shown in fig. 4, the first bottom surface of the first bar-shaped block 5 is attached to the substrate 7, and the first inclined surface 10 faces another monomer to be abutted. Since the first bar 5 is spaced apart from the edge of the substrate 7 to which it is attached, the first inclined surface 10 forms a concave structure having an obtuse angle with the edge of the substrate 7, and thus becomes a concave portion.
For the convex part, one side of the corresponding second bar-shaped block 6 is connected with the substrate 7, the other side of the corresponding second bar-shaped block protrudes out of the edge of the substrate 7, as shown in fig. 8, a second inclined surface 11 and a second bottom surface which are adjacent and distributed at an obtuse angle are arranged on the second bar-shaped block 6, the second bottom surface of the second bar-shaped block 6 is attached to the substrate 7, and the second inclined surface 11 faces another monomer to be abutted. Since the second bar 6 partially protrudes from the edge of the substrate 7 to which it is attached, a convex structure protruding from the substrate 7 is formed as a convex portion.
After the convex and concave parts of the adjacent single bodies are matched, the first inclined surface 10 of the first strip-shaped block 5 of the concave part is attached to the second inclined surface 11 of the second strip-shaped block 6 of the concave part, so that the first inclined surface and the second inclined surface are assembled and combined to form 180 degrees.

The buckle 3 has a concave shape and can be engaged with the concave and convex portions formed by joining two single bodies as shown in fig. 6. The clasp 3 is able to retain its shape when pressure is applied to the tie rod 2, so that pressure to the tie rod 2 is applied to the base plate 7 via the bar blocks, thus resisting the pressure exerted by the concrete.
For the situation that the width of the first strip-shaped block 5 and the second strip-shaped block 6 after being spliced is not matched with the buckle 3, the base plate 8 can be added on the side face of the first strip-shaped block 5 or the side face of the second strip-shaped block 6, the buckle 3 is matched stably due to the added width, and the constraint force of the buckle 3 on the direction parallel to the base plate 7 is guaranteed.

5. The formwork for elevator shaft construction according to claim 2, wherein the second bar-shaped block portion corresponding to the convex portion protrudes out of the edge of the base plate to form a convex structure protruding out of the base plate to form a convex portion; the protruding part of the second strip-shaped block is provided with a second inclined surface which is used for pressing the concave part.
6. The formwork for elevator hoistway construction according to claim 1, wherein the fastener includes a buckle and a counter-pull rod, the buckle is buckled on the concave portion and the convex portion after the butt joint, the concave portion and the convex portion are semi-surrounded, and the counter-pull rod is abutted to the buckle through the tensioning member.
7. The formwork for elevator hoistway construction according to claim 6, wherein the single body is provided with a relief structure through which the pair of tie rods pass, the relief structure being provided on the concave portion and the convex portion.
8. A form for use in elevator hoistway construction as defined in claim 6, wherein the fastener further includes a spacer on one side of the protrusion or recess, the spacer being co-embedded in the buckle in combination with the engaged recess and protrusion.
9. A method of operating a formwork for use in elevator hoistway construction as claimed in any of claims 1 to 8, comprising:
configuring the sizes and the numbers of the single bodies according to the sizes of the elevator shafts;
a plurality of monomers are lifted into the elevator shaft, bending lines of the monomers are attached to bottom corners of the inner wall of the elevator shaft, and side faces of the monomers are attached to side faces of the inner wall of the elevator shaft;
the edges of the adjacent monomers are spliced with the concave parts in a butt joint way, and fasteners are installed at the butt joint splicing positions;
pouring and curing are carried out after the formwork is supported, and the monomer is removed and lifted to the next construction layer for repeated use after the curing is completed.
10. The method of claim 9, wherein the reinforcing coupling is installed after the installation of the fastener in the hoistway is completed, the fastener is connected as a unit, and the reinforcing coupling is removed at the time of removal of the form.
