Description

Construction method of bottom die of arch structure

Technical Field

The invention relates to a construction method of an arch-shaped structure bottom die.

Background

With the development of social economy and the progress of construction technology, buildings showing individuation and stylization are increasing day by day, and the special-shaped concrete members are widely adopted in building design because of the characteristics of clear shape and unique shape. However, the special-shaped component also has the characteristics of complex structural form, high difficulty in template manufacturing, installation and reinforcement construction, high quality requirement and the like. The method aims to solve the problems that a bottom die plate with a part of arch structure is difficult to manufacture and install and the like.

In the traditional construction, if the arc radian is not large, the wooden template can be directly bent to a certain radian to manufacture by utilizing the plastic characteristic of the wooden template. However, when the radian is larger than the bending degree of the wood template, the problem of template fracture is very likely to occur by adopting the method. Therefore, when the requirement of the arch radian is large, a method of customizing a sizing template or processing and assembling the template in blocks is usually adopted in construction, which undoubtedly increases the construction cost, wastes the construction time and prolongs the construction period. If the manufacture and the installation are not proper, serious potential safety hazards exist.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides the arched structure bottom die construction method which is convenient to install and remove, can be repeatedly used, shortens the manufacturing time, avoids the waste of materials, and is time-saving, labor-saving and environment-friendly.

In order to solve the technical problem, the invention is realized as follows:

a construction method of an arch-shaped structure bottom die is characterized by comprising the following steps:

the method comprises the following steps: manufacturing a bottom die template;

step two: carrying out staggered cutting by adopting a cutting machine;

step three: manufacturing an inner-edge batten, and fixing the inner-edge batten on a bottom die template by using steel nails;

step four: manufacturing a bottom batten, fixing one end of the batten with one end of a bottom die template, gradually bending the bottom die template until the other end of the bottom die template is connected with the other end of the batten, and fixing by using a steel nail;

step five: manufacturing a rectangular template, and fixing the inner edge battens and the rectangular template one by one;

step six: manufacturing an inner support template and installing the inner support template, wherein the inner support template obliquely props against an upper inner edge batten, the lower part of the inner support template props against a rectangular template, and steel nails are adopted for oblique fixation;

step seven: and (4) supporting and reinforcing the manufactured and installed template according to a conventional rectangular hole template.

The arch structure bottom die construction method is characterized by comprising the following steps: and the cutting distance in the second step is 10 cm.

The arch structure bottom die construction method is characterized by comprising the following steps: the distance between the inner square wood blocks in the third step is 20 cm.

Detailed Description

As shown in fig. 1: a construction method of an arch-shaped structure bottom die comprises the following steps:

the method comprises the following steps: calculating the length and the width of the required bottom die template 1 according to the radian, the span and the width of the arch structure according to the requirements of a design drawing, and then cutting according to the size;

as shown in fig. 2: step two: the cutting machine is adopted for carrying out staggered cutting, the cutting size and the distance can be determined according to the structure radian and the width, and the distance is generally set to be 10 cm;

as shown in fig. 3 and 4: step three: manufacturing inner-edge battens 2 according to the length and the width of a bottom die template, fixing the battens on the template by steel nails, wherein the distance between the inner-edge battens is generally 20cm and can be adjusted according to the arc length and the radian;

as shown in fig. 5: step four: manufacturing a bottom batten 3 according to the span of the arch structure, fixing one end of the batten with one end of a bottom die template, gradually bending the bottom die template until the other end of the bottom die template is connected with the other end of the batten, and fixing by using a steel nail 6;

as shown in fig. 6: step five: cutting a rectangular template 4 according to the height and the span of the arch, and fixing battens and the template one by one, wherein the battens and the template are required to be firmly fixed;

as shown in fig. 7 and 8: step six: manufacturing an inner supporting template 5, determining the size of the inner supporting template according to the distance between the inner edges, installing the inner supporting template, obliquely supporting the upper inner edge batten by the inner supporting template, and obliquely and firmly fixing by using steel nails 6, wherein the lower part of the inner supporting template supports the rectangular template;

The invention is mainly completed by cutting and assembling the on-site wood template and the battens. The wood template has certain shaping and bearing capacity and can be bent to a certain radian, but when the radian requirement is larger, the wood template is easy to break. According to the method, the template is staggered and half-cut, so that the template has certain bearing capacity while being bent to the maximum extent, the template cannot be easily broken, the construction difficulty is reduced, and the construction safety is improved.
