A kind of circulation adjustable angle iron stiffening system and processing method
Technical field
The present invention relates to the technical field of construction in civil engineering, be specifically related to a kind of circulation adjustable angle iron stiffening system and job practices thereof.
Background technology
Existing concrete difference of height lines form erecting technology is: adopt laminate, flitch to support or directly use the steel pipe enclosing, technique shortcoming: easily distortion, positioning in building, the integrated support system effect is poor, and be difficult to guarantee that the negative and positive angle is upright, after form removal, the difference of height lines are not straight, and the difference of height place causes concrete that certain waste is arranged simultaneously.
Laminate, flitch support or directly adopt steel pipe enclosing support system to reinforce the difference of height formwork system, whole rigidity and stress performance are poor, also have influence on construction efficiency, cause circulation material to waste in a large number, thereby become the key link in the design of difference of height linear support system.Because the power transmission of existing support system node is unclear, support node is dealt with improperly, and is random large, so in the urgent need to a kind of, have good stress performance and an economical and practical a kind of circulation adjustable angle iron stiffening system.
Summary of the invention
The object of the invention is to overcome problem and the shortcoming that above-mentioned prior art exists, a kind of circulation adjustable angle iron stiffening system and job practices thereof are provided.Angle iron stiffening system power transmission of the present invention is clear and definite, easy for installation, when concreting, can control effectively that formwork system is indeformable, positioning, and after form removal, Surface Quality of Concrete is good, and does not cause the concrete waste.
Purpose of the present invention is achieved through the following technical solutions:
Circulation adjustable angle iron stiffening system, comprise angle steel, bolt, steel plate, adjustable link, monolithic angle steel, put cutting eight angle steel two or two at 45 ° together welding, in the termination of angle steel, the termination of monolithic angle steel welds respectively a steel plate and comes concordant,, by steel plate and bolt joint forming, fix two adjustable links with bolt between the monolithic angle steel of up and down between angle steel, monolithic angle steel.
Circulation adjustable angle iron stiffening system of the present invention also comprises strut, and strut is welded between two angle steel, forms the triangle of stability, so just strengthens angle steel rigidity.
The processing method of a kind of circulation adjustable angle iron stiffening system of the present invention, comprise the steps:
(1) determine to select the angle steel specification according to kitchen, washroom, balcony or indoor flooring difference of height, meet rigidity and welding needs;
(2), according to the size of kitchen, washroom, balcony or indoor flooring, determine the length of monolithic angle steel;
(3) steel plate is determined the boring size according to the bolt size;
(4) cutting of the angle steel that will choose is at 45 °, and two or two put welding together, carry out respectively angle steel and Plate Welding and angle steel the strut welding and, the bolt sleeve of the welding of monolithic angle steel and steel plate, adjustable link support and connection place and monolithic angle steel weld;
While (5) constructing, angle steel is connected and tightens with bolt by steel plate with the monolithic angle steel, and adjustable link supports with the monolithic angle steel is with bolts and tightens, after whole circulation adjustable angle iron stiffening system forms integral body, after place, four angles adopted iron wire and reinforcing bar binding firmly, concreting got final product.
The relative prior art of the present invention has following advantage and beneficial effect:
(1) power transmission is clear and definite, and the present invention utilizes support bar, adjustable link to support and bolt connects, and bears moment of flexure, shearing is reasonable, and integral rigidity, intensity are good.
(2) conveniently, work efficiency is high for installation, disassembling section, and construction is fast, and can make standardization and regularization, various welding jobs all can be completed in factory, need to complete bolt connection work for on-the-spot, greatly reduce on-the-spot welding job, carried out quickly installation or removal.
(3) this support system can be reused, and greatly reduces costs.
(4) circulation adjustable angle iron stiffening system guarantee in washroom, when kitchen, balcony or indoor flooring difference of height formwork, concrete is built moulding, lines are attractive in appearance, upright.

The specific embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples, but embodiments of the present invention are not limited to this.
As shown in Figure 1, circulation adjustable angle iron stiffening system is comprised of angle steel 1, bolt 2, steel plate 3, strut 4, adjustable link 5, monolithic angle steel 6, put cutting eight angle steel 1 two two at 45 ° together welding, strut is welded between two angle steel, form the triangle of stability, so just strengthen angle steel rigidity; In the termination of angle steel 1, that a steel plate 5 is welded respectively in the termination of monolithic angle steel 6 is concordant,, by steel plate 5 and bolt 2 joint formings, fixes two adjustable links 5 with bolt between the monolithic angle steel 6 of up and down between angle steel 1, monolithic angle steel 6.
Fig. 2 is monolithic angle steel 6 and steel plate 3 single-sided weldings in circulation adjustable angle iron stiffening system, and 3 of steel plates are concordant with monolithic angle steel 6 ends.
Fig. 3 is two angle steel 1 terminations and steel plate 3 single-sided weldings after being welded in circulation adjustable angle iron stiffening system, and 3 of steel plates are concordant with angle steel 1 end, near angle steel 1 termination with strut 4 welding.
Fig. 4 connects between monolithic angle steel 6 by bolt 2 and connects in circulation adjustable angle iron stiffening system.
Fig. 5 is that in circulation adjustable angle iron stiffening system, intermediate supports adopts adjustable link 5 to support, and, at monolithic angle steel 6 place's weld bolts 2, by bolt 2, with monolithic angle steel 6, is connected.
The processing method of this circulation adjustable angle iron stiffening system is as follows:
(1) determine to select the angle steel specification according to kitchen, washroom, balcony or indoor flooring difference of height, meet rigidity and welding needs;
(2), according to the size of kitchen, washroom, balcony or indoor flooring, determine the length of monolithic angle steel;
(3) steel plate is determined the boring size according to the bolt size;
(4) cutting of the angle steel that will choose is at 45 °, and two or two put welding together, carry out respectively angle steel and Plate Welding and angle steel the strut welding and, the bolt sleeve of the welding of monolithic angle steel and steel plate, adjustable link support and connection place and monolithic angle steel weld;
While (5) constructing, angle steel is connected and tightens with bolt by steel plate with the monolithic angle steel, and adjustable link supports with the monolithic angle steel is with bolts and tightens, after whole circulation adjustable angle iron stiffening system forms integral body, after place, four angles adopted iron wire and reinforcing bar binding firmly, concreting got final product.
In this circulation adjustable angle iron stiffening system, angle steel, adjustable link, steel plate and bolt adopt Q235-B, strut reinforcing bar HRB335, and welding rod adopts the E43 type, and weld seam reaches the second-order weld quality requirement.
Said, can realize preferably the present invention.
