Connecting method for demountable wooden door

Abstract

The invention discloses a connecting method for a demountable wooden door. A four-section two-point connecting method is adopted for connection of hardware in a doorframe and rail of the demountable wooden door, and connecting components are divided into an unthreaded hole hammerhead, a male-female stud, a fastening bolt and a nut hammerhead. By the male-female stud, the shortcomings of poor fastening firmness and loosening of a conventional turnbuckle are overcome. The male-female stud is formed to achieve fixation effects. The problem that a demounting aim cannot be accurately fulfilled because counterclockwise rotating fastening is adopted for two-point connection of the nut hammerhead, a stud and a double-end internal thread tube in a process of demounting the wooden door by virtue of a conventional demountable wooden door connecting technology is completely solved. By the male-female stud, the demounting aim can be accurately fulfilled (the male-female stud is separated from the nut hammerhead). The fastening bolt is fixed innovatively by inserting the unthreaded hole hammerhead into the doorframe, and the fixing position of the fastening bolt can be mastered better.

Description

1. Technical background [0001] A connection method for detachable wooden doors belongs to the field of design and manufacture of indoor and outdoor wooden doors and windows. 2. Background technology [0002] Our company has invented a connection method using four sections and three points. [0003] From the point of view of the connection method, the connection components are divided into stud bolts, double-head inner wire pipes, fastening bolts, and nuts with vertical heads. The connection method is as follows: (1) first insert the nut vertical head into the nut hole of the wooden door riser, (2) screw one end of the double-headed fastening bolt into one end of the double-headed inner wire tube, thus forming a male and female double-headed bolt, The male and female stud bolts that are combined are inserted into the bolt holes of the wooden door riser, and then screwed into the inner thread holes of the nut vertical head by the bolt heads of the male and female stud bolts. ...

AI Technical Summary

Problems solved by technology

The following is a detailed description of its disadvantages: (1) Screw one end of the stud bolt into the end of the double-ended inner wire tube to fasten. In terms of technology, this operation requires one more process and increases the working hours.

(2) Screw one end of the stud bolt into the end of the double-headed inner wire tube and fasten it. The turnbuckle is still not fastened firmly enough, and there is looseness, which reduces the effect of fixing.

When disassembling the hardware connected to the wooden door, the stud bolts and nuts need to be separated vertically. When the inner wire tube is rotated clockwise to disassemble, the part where one end of the stud bolt is screwed into the inner wire tube will be separated first, while the other end is screwed into the inner wire tube. Into the nut pendant but can not be disassembled

Unable to achieve the purpose of disassembly

(4) For wooden doors fixed with fastening bolts, if the fastening bolts are rotated too hard, the fastening bolts will enter the wooden door. If the fastening bolts are too small to be rotated, the connection will not be firm

It is difficult to grasp the scale of fixing fastening bolts
