Abstract
A method and apparatus for precasting hollow thin-wall column is disclosed. Said apparatus is composed of L-shaped upper and lower steel formworks with multiple arc bases on their external side surfaces, and two locating and leakage-resistant parts, which can be combined to form a sealed square mould.
Description
Technical field:
The hollow thin shell column that the present invention uses about building construction is particularly about a kind of manufacture method and shaped device thereof of precasting hollow thin shell column.
Background technology:
Generally when the building building construction, its skeleton has reinforced concrete skeleton frame and steel skeleton etc., and when the reinforced concrete skeleton frame building construction, some is in job site, building reinforcement placing and template, then penetration concrete forms pillar, some then at precasting factory precasting hollow thin shell column, is worn and is transported to the job site, building, utilizes vertical construction method that it is combined with pedestal or beam; When utilizing the former method building construction building pillar, need at the every pre-fixed reinforcing bar of pillar base position and after setting up fixed form, the work of being in the milk again, and after need waiting until the concrete setting in the template, just can carry out next engineering, dislike slowly slightly on the time in building, can prolong the construction period in building; And when utilizing the latter's method building construction building pillar, though can be at the good required hollow thin shell column of precasting factory precasting, but because of the hollow thin shell column is the solid strut that reinforcing bar and concrete synthesized, weight is quite heavy, can cause cost to increase and inconvenience when carrying and site operation.
Therefore, the inventor in view of this, be that the spy concentrates on studies and process is constantly discussed improvement, a kind of precasting material weight that reduces is proposed finally, be beneficial to and hang a liter carrying assembling, strengthen the beam column quality, but and the reduction of erection time, increase productivity and can effectively improve the manufacture method and the shaped device thereof of a kind of hollow thin shell column of above-mentioned shortcoming.
Summary of the invention:
The technical problem that institute's desire solves
The present invention mainly is to solve known when the building building construction, in job site, building reinforcement placing and template, then penetration concrete forms pillar, or some is at precasting factory precasting hollow thin shell column, wear again and be transported to the job site, building, utilize vertical construction method with itself and methods such as pedestal or beam combine all fail effective reduction of erection time, shortcoming such as increase productivity.
The technological means of dealing with problems:
Construction engineering is the important ring of capital construction always, it also is the basis of economic development, reduction of erection time and to improve the engineering quality be requirement most important and that can not compromise how effectively, therefore main purpose of the present invention provides a kind of precasting material weight that reduces, be beneficial to and hang liter the carrying assembling, and strengthen beam column quality, reduction of erection time, the manufacture method and the shaped device thereof of a kind of hollow thin shell column of increasing productivity.
For reaching the foregoing invention purpose, the technological means that the present invention used is to provide a kind of shaped device, this device is by a L shaped location punching block of going up, one L shaped location punching block down and two location leakage barriers constitute, the L type is located punching block up and down on its lateral surface, all be provided with the arc runners of a plurality of suitable circular arcs, the precasting thickness of default pre-cast concrete on the limit, leakage barriers four sides, location, and by combinations thereof, form the precasting appearance of the long tubular in an airtight four directions, front and back form two openends and a, b, c, four inner edge precastings of d face, L shaped locate punching block combination up and down after, arc runners on its lateral surface contacts with each other, on its crust of the device face, form circular circular arc runners, can make device form the state that face is changed in rolling, and get the moulding of an inner edge precasting of precasting face; And its inside of hollow thin shell column is stood and is formed by complex banded column steel reinforcement cage structural arrangement, group, and on its two side opposite the angle, respectively be provided with one and run through the work muscle that links all banded column steel reinforcement cages and outwards give prominence to, steel reinforcement cage can be inserted the inside sky portion after the combination of location punching block under punching block and the L type of locating on the above-mentioned L type, and its work muscle is piercing in outside the pre-buried via hole of above-mentioned location leakage barriers.
Manufacture method of the present invention mainly comprises the following step:
Steps A:
By L shaped precasting appearance of locating the long tubular in punching block group upright be combined into one airtight four directions up and down, two openends of front and back formation and a, b, c, four inner edge precastings of d face, wherein the arc runners seat of a face stands on the ground, makes a face firm state of formation on ground that lies low; The steel reinforcement cage structure of hollow thin shell column inner skeleton is inserted its inner space by openend, and above-mentioned location leakage barriers is installed in open end, the work muscle of establishing on the steel reinforcement cage is piercing in outside the default pre-buried via hole of location leakage barriers, and finish the installing of single unit system, use the peripheral concrete precasting area that forms the hollow thin shell column;
Step B:
Concrete poured into lie low, until the preset thickness identical (if exceed the preset thickness of locate leakage barriers then can overflow) of its thickness with the location leakage barriers, wait concrete setting in a on ground face inner edge precasting face inside;
Step C:
After treating that a surface concrete solidifies, circular arc runners on the use device shell surface will install to roll forward and change face, replace the b face and lie low in ground, concrete be poured into to lie low in the b on ground face inner edge precasting face inside again, identical until its thickness with the preset thickness of location leakage barriers, wait for concrete setting;
Step D:
According to its aforesaid step C, wait to lie low after the concrete setting of the inner edge precasting face precasting on ground, the circular arc runners on it use device shell surface will install rolls one by one changes face, c face, the d face of replacement remainder, and concrete perfusion treats that it solidifies;
Step e:
After treating that a, b, c, four inner edge precastings of d surface concrete all solidify, then remove location leakage barriers and the L shaped punching block of locating up and down, its apparatus structure is separated, carry out demoulding action, and spiral shell is established on the work muscle of suspension ring joint outside being exposed to, formation can be hung the suspension ring that rise, and finishes the manufacturing of precasting hollow thin shell column.
Via the execution of shaped device combination and above-mentioned steps, when enforcement, can simplify the whole construction flow process significantly, and reduce the precasting material weight, be beneficial to and hang a liter carrying assembling, strengthen the beam column quality and also significantly increase productivity.
