Abstract
The invention discloses an installation process of an elevator shaft formwork, comprising: manufacturing a filter net first, sizing a water-permeable bottom form to 2200 mm * 2200 mm in length and width, and drilling holes 20 mm in diameter in the form at intervals of 200 mm; combining an elevator shaft box formwork side form and the water-permeable bottom form into a box body, fixing the filter net to the bottom of the box body through fixing nails 4, turning up the filter net by 50 mm, reinforcing the elevator shaft box formwork according to normal construction, pouring concrete finally, removing the elevator shaft box formwork for reuse after the concrete reaches certain strength, and repairing the bottom of an elevator shaft with pure mortar after the formwork is removed since part of the bottom concrete mortar flows into the formwork. The elevator shaft formwork is simple in structure and convenient to use and can be installed quickly and reliably, one-off forming rate of elevator shaft concrete is improved, forming quality of concrete is effectively improved, construction time is shortened, and construction cost is reduced.
Description
Technical field
The present invention relates to the installation steps of a kind of hoistway formwork.
Background technology
Now, this phenomenon is there is during cast in situs elevator concrete, being exactly in casting process, hoistway formwork floats, and causes elevator out of shape, usual method is preloading above hoistway formwork, if carpenter does not support below template, above template, pressure is excessive, and the reinforcing bar basis that can cause elevator surrounding is impacted, elevator surrounding reinforcing bar is caused to cave in, thus affecting mass of foundation.Also having be exactly welding wire drawing below template, is soldered on reinforcement foundation, by the possibility of bottom reinforcement bars pull-up when the method is also possible to cause Form floating, descends earth anchor besides, and the waterproof talking about infrastructure of lower earth anchor is damaged certainly, and this is unallowed.In the face of these problems, at this, more optimal method has been had for hoistway formwork installation, i.e. a kind of Lift well mould board mounting assembly, this device construction method is a kind of method that comparison is easy, economic, feasible, material therefor can find at the construction field (site), and field fabrication template extremely convenient.The method is easy and simple to handle, easy construction, prevents the floating of template during casting concrete, causes later stage substantial amounts of patch work, greatly improves elevator Forming Quality.
Summary of the invention summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, it is provided that the installation steps of a kind of hoistway formwork, it is possible to effectively solve the problem in background technology.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The installation steps of a kind of hoistway formwork of the present invention, first make filter screen, being processed into the size that length and width are 2250mmX2250mm, permeable bed die is processed into the size that length and width are 2200mmX2200mm, and bores the hole of a 20mm diameter on template face every 200mm；Elevator case mould side form 15mm thickness plank sheathing makes, elevator case mould side form and permeable bed die are combined into casing, and filter screen is fixed with fixing nail at box bottom, filter screen turns over 50mm, then according to elevator case mould is reinforced by normal construction, last casting concrete, reach after intensity until concrete, elevator case mould is removed recycling, simultaneously because lower concrete mortar has part to be lost to inside template, after form removal, to repair with sharp sand slurry bottom elevator.
As a preferred technical solution of the present invention, filter screen, filter screen adopts 3# steel fabric sheet.
As a preferred technical solution of the present invention, permeable bed die adopts 15mm thickness plank sheathing.
As a preferred technical solution of the present invention, elevator case mould side form height is 2500mm, and width is 2200mm.
The present invention reaches to provide the benefit that: body series adopts Lift well mould board mounting assembly to complete elevator concreting work easily, it is to avoid the various mass defects that conventional construction method brings.Be not only simple in structure, easy to use, it is possible to quick, be reliably completed the installation of hoistway formwork, improve elevator concrete one-shot forming rate, the effective concrete Forming Quality improved, decrease the engineering time, reduce construction cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
Embodiment: as Figure 1-3, the installation steps of a kind of hoistway formwork of the present invention, first make filter screen 1, it is processed into the size that length and width are 2250mmX2250mm, permeable bed die is processed into the size that length and width are 2200mmX2200mm, and bores the hole of a 20mm diameter on template face every 200mm；Elevator case mould side form 3 15mm thickness plank sheathing makes, elevator case mould side form and permeable bed die are combined into casing, and filter screen is fixed with fixing nail 4 at box bottom, filter screen 1 turns over 50mm, then according to elevator case mould is reinforced by normal construction, last casting concrete, reach after intensity until concrete, elevator case mould is removed recycling, simultaneously because lower concrete mortar has part to be lost to inside template, after form removal, to repair with sharp sand slurry bottom elevator.
Further, filter screen 1 adopts 3# steel fabric sheet.Permeable bed die adopts 15mm thickness plank sheathing.Elevator case mould side form height is 2500mm, and width is 2200mm.
Body series adopts Lift well mould board mounting assembly to complete elevator concreting work easily, it is to avoid the various mass defects that conventional construction method brings.Be not only simple in structure, easy to use, it is possible to quick, be reliably completed the installation of hoistway formwork, improve elevator concrete one-shot forming rate, the effective concrete Forming Quality improved, decrease the engineering time, reduce construction cost.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature carries out equivalent replacement.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
