With the tool type square steel pipe fastener, the operation can be easily carried out in a construction field, and concrete bubbles can be also controlled; and therefore, the efficiency and the quality of building construction are improved.
Description
Technical field
The utility model relates to girth member and the construction technology of the frame column wooden form in the realm of building construction, particularly a kind of tool-type square steel pipe securing member.
Background technology
At present, in construction site, what the wooden form reinforcing of frame column was substantially all adopted is fastener-style steel pipe scaffolding and the middle method that adds split bolt, this method is reinforced complex procedures, should not operate, materials demand is many, and the middle part needs to add through-wall bolt and reinforces, bolt hole can be left in the frame column surface, and aesthetic property can not guarantee; Another kind is to use large form, although the large form handled easily, due to the brushing release agent, the bubble after vibrating is not easy to discharge, and causes presentation quality poor; Therefore, how to improve frame column formwork speed and build concrete quality after completing, become the technical problem that the building field technician needs to be resolved hurrily.
Adopt tool-type square steel pipe securing member, the job site is easily operated, and can control the concrete bubble, improve efficiency of construction and quality.
The utility model content
The purpose of this utility model is to provide a kind of tool-type square steel pipe securing member, implements the wooden form of frame column is reinforced, to improve frame column formwork speed and to build concrete quality after completing.
For achieving the above object, the technical solution of the utility model is: a kind of tool-type square steel pipe securing member, it comprises the securing member that two symmetries of combining by bolt, nuts and bolt hole are placed, each securing member connects member, member A and member B by group and is welded to form, the centre that connects member in group has a penetrating bolt hole, group connects an end plane and himself this external surface angle at 45 ° of member, and its another end plane and himself this external surface are at an angle of 90; The end plane of member A and member B and himself this external surface angle at 45 °, its another end plane and himself this external surface are at an angle of 90; The one welding is carried out in the 45° angle end of member A and member B, make it orthogonal, carry out the one welding with the 45° angle end that group connects member respectively at the other end of member A and member B, make two outside angles become 135 ° of angles.When the length of member A and member B is identical, be a square tool-type square steel pipe securing member, when the length of member A and member B not simultaneously, be a rectangle tool-type square steel pipe securing member.
Member A and member B can adopt hollow square steel pipe or other hollow the prismatic body material to be arranged, to guarantee the stress performance requirement of securing member.
Owing to adopting tool-type square steel pipe securing member, the job site is easily operated, can also control the concrete bubble, improved efficient and the quality of building operations.

The specific embodiment
Below in conjunction with accompanying drawing, tool-type square steel pipe fastener constructions, construction are described in further detail:
As seen from Figure 1, tool-type square steel pipe securing member comprises the securing member that two symmetries of combining by bolt, nuts and bolt hole are placed.Each securing member connects member 1, member A 2 and member B 3 by group and is welded to form, and the centre that connects member 1 in group has a penetrating bolt hole 4, and bolt hole 4 is used for connecting with another group the use of member 1 connection.Group connects an end plane and himself this external surface angle at 45 ° of member 1, and another end plane of group company member 1 and himself this external surface are at an angle of 90.The end plane of member A 2 and member B 3 and himself this external surface angle at 45 °, its another end plane and himself this external surface are at an angle of 90.The one welding is carried out in the 45° angle end of member A 2 and member B 3, make it orthogonal, the other end at member A 2 and member B 3 carries out the one welding with the group even 45° angle end of member 1 respectively, make the angle of two outsides become 135 ° of angles, be welded into a securing member, the unified E43 welding rod that adopts in welding position welds.Two welding securing members are made up by bolt 7, nut 8, bolt hole 4, can form complete the rectangle tool formula square steel pipe securing member.When the length of member A 2 and member B 3 is identical, be a square tool-type square steel pipe securing member, when the length of member A 2 and member B 3 not simultaneously, be a rectangle tool-type square steel pipe securing member.
To the frame column of homomorphs not, by changing size, number, the combination angle of member A 2 and member B 3, can obtain rhombus, polygonal tool-type square steel pipe securing member, be used for difform frame column is reinforced.
According to the physical size of frame column, member A 2 and member B 3 can adopt hollow square steel pipe or other hollow the prismatic body material to be arranged, and its basic condition is the stress performance requirement that will guarantee securing member.
By Fig. 2, Fig. 3 as seen, determine to adopt the quantity of tool-type square steel pipe securing member during construction according to the frame column frame size, its selection of material usually carries out the square steel specification according to the size of frame column and selects, and sees the following form:
| The frame column size | The square steel pipe length of side (mm) | Square steel pipe thickness (mm) | Theoretical weight (kg/m) | Remarks |
| 900 | 50 | 5 | 6.73 | ? |
| 800 | 50 | 5 | 6.73 | ? |
| 700 | 45 | 5 | 5.95 | ? |
| 600 | 40 | 5 | 5.16 | ? |
| 500 | 40 | 5 | 5.16 | ? |
At the construction field (site), also need to calculate example to the concrete size of member of tool-type square steel pipe securing member as follows: carry out size according to the thickness of cross-section of frame column size, flitch 6, composite board 5 etc. and calculate, the length of member A 2=flitch height * 2+ composite board thickness * 2+a+ square steel pipe width; The length of member B 3=flitch height * 2+ composite board thickness * 2+b+ square steel pipe width, in following formula: a is that framework column length limit size, b are frame column minor face size.
Above-mentioned explanation to disclosed embodiment, this area professional and technical personnel can be realized easily, multiple modification to embodiment will be apparent concerning those skilled in the art, the defined General Principle of the present invention can without departing from the present invention, realize in other embodiments; Therefore, the present invention is not restricted to embodiment illustrated herein, but will meet the wider scope consistent with principle disclosed herein and features of novelty.
