Abstract
The utility model discloses a wrench for installing air pipes of total plate flanges, and belongs to the technical field of ventilating and air-conditioning engineering installation. The wrench comprises a wrench head and a handle. The wrench head comprises a four-section jaw, a steel strip is sequentially inwardly bent to form the four-section jaw, a first section, a second section, a third section and a fourth section of the four-section jaw are sequentially connected with one another, and a notch is formed in a position between a free end of the first section and a free end of the fourth section; the handle is perpendicularly installed in the center of the back of the third section. The wrench has the advantages that when the wrench is used, a flange on a side of the wrench is clamped by the first section of the jaw at first, an operator forcefully presses the handle, and the fourth section of the jaw moves towards another flange and presses the other flange, so that the two flanges can cling to each other; hooks and corners can be installed while the flanges keep in clinging states, so that time and labor can be saved; the handle can be reset after the flanges are installed, and only needs to be taken down; working hours for installing each connector can be saved by 40% at least as compared with a condition before the wrench for installing the total plate flanges is used; the wrench is simple in structure and easy to manufacture and process, and is a high-quality, inexpensive and practical tool easy to popularize, and the like.
Description
Technical field
The utility model belongs to heating ventilation and air-conditioning project installation technical field, is specifically related to a kind of for being connected and installed the aid of common plate-type flange airduct.
Background technology
Along with the raising of building function and design standard, heating and ventilating pipeline system is increasingly sophisticated, and installation workload also day by day increases.(mainly refer to adopt iron sheet and angle steel flange riveted joint with the rectangular air duct of traditional form, each saves air duct flange wing and with bolt, is connected to form the form in air channel) compare, plate-type flange airduct inleakage is little altogether, can reduce energy consumption, save operating cost, can save material, reduce construction investment, also there is the simple, fast advantage of processing and fabricating simultaneously.Therefore in engineering, the application of plate-type flange airduct is increasingly extensive altogether.
The processing of plate-type flange airduct installation order is altogether: after segmental machining completes, lifting is to target location; Fix each section and utilize hook code (banjo clip), corner brace by joint seal of flanges.Because airduct volume, weight are larger, if there is no suitable aid, hold-down hook code will be a job that expends very much man-hour.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, significant aid of effect for the installation of board-like barlan airduct altogether.
Based on above-mentioned purpose, the utility model has been taked following technical scheme: for the spanner of common plate-type flange airduct is installed, comprise driving end and handle, described driving end is four sections of tiger's jaws that bent inwards successively and formed by steel band, one section, two sections, three sections, four sections join successively, between one section and four sections of free ends, have breach; Handle is vertically mounted on the back central authorities of three sections.
Described one section is 90 °～105 ° with two intersegmental angles, and the angle between two sections and three sections is 90 °～110 °, and three sections is 115～130 ° with the angle of four sections.
Described one section is 90 ° with two intersegmental angles, and the angle between two sections and three sections is 101 °, and three sections is 128 ° with the angle of four sections.
The length of described one section is 12～15mm; The length of two sections is 14～18mm; The length of three sections is 30～35mm; The length of four sections is 20～25mm.
The length of described one section is 13mm; The length of two sections is 15mm; The length of three sections is 32mm; The length of four sections is 22mm.
Described thickness of strips is 5mm.
During use, first make one section, tiger's jaw block a side flange, firmly depress handle and make four sections, tiger's jaw move and be pushed down to another flange direction, two flanges are adjacent to.Hold-down hook code and corner brace under the state that keeps being close at flange, laborsaving saving time.After installation, handle is resetted, take off this spanner.Use this instrument that plate-type flange is altogether installed, with use before compare, each interface can be saved man-hour more than 40%.
Visible, use this instrument not only can significantly reduce workman labour intensity, increase work efficiency, unusual convenient and efficient, meanwhile, that this instrument also has is simple in structure, be easy to the advantages such as production and processing, be a inexpensive, be easy to the utility promoted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For the spanner of common plate-type flange airduct is installed, as shown in Figure 1, comprise driving end 1 and handle 2, driving end 1 is four sections of tiger's jaws that bent inwards successively and formed by the thick galvanized steel strip of 5mm, one section of 1-1, two sections of 1-2, three sections of 1-3, four sections of 1-4 join successively, between one section of 1-1 and four sections of 1-4 free ends, have breach; Handle 2 is vertically mounted on the back central authorities of three sections of 1-3.The length of one section of 1-1 is 13mm, and the length of two sections of 1-2 is 15mm, and the length of three sections of 1-3 is 32mm, and the length of four sections of 1-4 is 22mm; Angle α=90 ° between one section of 1-1 and two sections of 1-2, angle β=101 ° between two sections of 1-2 and three sections of 1-3, the angle of three sections of 1-3 and four sections of 1-4 is γ=128 °.
Manufacturing process is as follows: use the wide thick galvanized steel strip of 5mm of plate shearing machine clip 82mm length * 50mm; From steel band one end, start with folder more not in its 13mm place, 28mm place, the bending of 60mm place, require angle α=90 ° between one section of 1-1 and two sections of 1-2, angle β=101 ° between two sections of 1-2 and three sections of 1-3, the angle of three sections of 1-3 and four sections of 1-4 is γ=128 °.After these four sections of bendings, be tiger's jaw shape, form driving end 1.With one section, long 16 round steel of cutting machine intercepting 160mm, as handle 2, be welded on the back central authorities of the 3rd section of 1-3.Remove each arris burr polishing, get product.
The present embodiment is not unique embodiment of the present utility model; can also there be a lot of modes of texturing; such as in the size range that can ask for protection in claim, concrete size being adjusted; or the steel band that adopts other materials to make; or the thickness of adjustment steel band; or adopt other forms of handle installation form, etc.
