The problem that intensity difference causes purlin quality bad.
Exempt from branch die combination purlin to the present invention below in conjunction with the accompanying drawings to illustrate.
As shown in Figures 1 to 4, the present invention exempt from branch die combination purlin include a pair of of the channel steel 10 for being set to the top of support pile 91,
The split bolt 11 of drawknot connection channel steel 10, the concrete structure 20 that pours and be formed between a pair of of channel steel 10 and it is embedded in concrete knot
Steel reinforcement cage 30 in structure 20.
Wherein, as shown in Fig. 1, Fig. 3 and Fig. 7, channel steel 10 includes a web and the flange plate for being fixedly arranged on web both sides, channel steel
10 opposite facing settings, i.e. flange plate are located at side of the web far from support pile 91.Channel steel 10 is placed on ground, a pair of of channel steel 10 it
Between be formed with casting space, and the top of support pile 91 is located in the casting space, by pouring coagulation in the casting space
To form concrete structure 20, the top of support pile 91 and split bolt 11 are anchored at interior soil by concrete structure 20.Preferably, to drawing spiral shell
After 11 drawknot of bolt connects channel steel 10, the surface of support pile 91 is tightly attached in the side surface of the web of channel steel 10.
As shown in Figures 2 to 4, steel reinforcement cage 30 is first placed in casting space before casting concrete, and steel reinforcement cage 30 is avoided
Support pile 91 is arranged, and after concrete structure 20 pours, steel reinforcement cage 30 is embedded in concrete structure.Increase concrete structure 20 by steel reinforcement cage 30
Intensity, and then the stability of enhancing structure entirety.
The bolt hole for adapting to split bolt 11 is offered on the web of channel steel 10,11 both ends of split bolt pass through corresponding
Bolt hole is simultaneously connected with corresponding channel steel 10, and specifically, the nut of split bolt 11 is tightly abutted against web far from support pile 91
Side on, to which drawknot connects a pair of of channel steel 10.And after concrete structure 20 pours, split bolt 11 is through concrete structure 20 and right
It draws bolt 11 to be anchored in concrete structure 20, increases the bonding strength of channel steel 10 and concrete structure 20.
Preferably, split bolt 11 is arranged between two neighboring support pile 91, prevent the setting of split bolt 11 to perpendicular
To support pile 91 have an impact.And vertically three split bolts 11 of interval setting between two neighboring support pile 91, pass through
Between the quantity for increasing split bolt 11 increases the contact area of split bolt 11 and concrete structure 20, and split bolt 11 is vertical
Every setting so that 10 vertical applied force of channel steel is uniform, ensures that 10 surface of channel steel is closely affixed with 91 surface of support pile, enhance structure
Overall stability.
In a preferred embodiment, as shown in Figure 5 and Figure 6, channel steel 10 includes the multistage channel steel section of splicing connection, slot
Junction between steel section is welded with connection strap 12 with fixation.The end face of two sections of adjacent channel steel sections to pair and fit, connect
The web surface of the side surface of the front half section of item 12 and a channel steel section is affixed and welds, and the side surface of second half section and another channel steel
The web surface of section is affixed and welds, to be fixedly connected with two sections of channel steel sections.Preferably, connection strap 12 is reinforcing rod, channel steel
There is a plurality of the connection strap 12 of junction, and interval setting in a vertical direction between section, to enhance consolidating between channel steel section
Determine intensity, and make channel steel section junction uniform force, enhances the stability of channel steel entirety.
The construction method for exempting from branch die combination purlin to the present invention below in conjunction with the accompanying drawings illustrates.
The construction method that the present invention exempts from branch die combination purlin includes：
As shown in Fig. 1, Fig. 3 and Fig. 7, a pair of of channel steel 10 is set up at the top of support pile 91, and channel steel 10 is placed in ground
On so that casting space is formed between a pair of of channel steel 10, and the top of support pile 91 is located in the casting space, then utilizes
11 drawknot of split bolt connection a pair of channel steel 10.
Specifically, channel steel 10 includes a web and the flange plate for being fixedly arranged on web both sides, is opened up on the web of channel steel 10
Adapt to the bolt hole of split bolt 11.By the opposite facing both sides being arranged at the top of support pile 91 of a pair of of channel steel 10, i.e. flange plate
It is arranged positioned at side of the web far from support pile 91, and the surface of the web of channel steel 10 is tightly affixed on to the table of support pile 91
Face.Then the both ends of split bolt 11 are each passed through corresponding bolt hole and screw togather nut, channel steel 10 is resisted against by nut
Web so that split bolt 11 be connected with corresponding channel steel 10.
Preferably, being arranged split bolt 11 between two neighboring support pile 91, the setting pair of split bolt 11 is prevented
Vertical support pile 91 has an impact.And vertically three split bolts 11 of interval setting between two neighboring support pile 91, lead to
The quantity for increasing split bolt 11 is crossed, increases surface area of the split bolt 11 in casting space, and split bolt 11 is vertical
Interval setting is so that 10 vertical applied force of channel steel is uniform, and guarantee 10 surface of channel steel is closely affixed with 91 surface of support pile, and enhancing finishes
Structure overall stability.
As shown in Figures 1 to 4, steel reinforcement cage 30 is set up in casting space, and steel reinforcement cage 30 is made to avoid the setting of support pile 91,
Then in casting space casting concrete to form concrete structure 20.The concrete structure 20 is by the top of support pile 91, split bolt
20 and in steel reinforcement cage 30 is anchored at, increase the intensity of concrete structure 20 by steel reinforcement cage 30, and pass through split bolt 20 and increase concrete
The bonding strength of structure and channel steel 10.
In a preferred embodiment, as shown in Figure 5 and Figure 6, channel steel 10 includes multistage channel steel section, and the construction method is also
Including：More connection straps 12 are provided, it is the end face of two sections of adjacent channel steel sections is opposite and be affixed, then by the first half of connection strap 12
The side surface of section and the web surface of a channel steel section are affixed and weld, and the web table of the side surface of second half section and another channel steel section
Face is affixed and welds, to be fixedly connected with two sections of channel steel sections.Preferably, connection strap 12 is reinforcing rod, connect between channel steel section
It meets place and welds a plurality of connection strap 12, and interval setting in a vertical direction, to enhance the fixing intensity between channel steel section, and
Make channel steel section junction uniform force, enhances the stability of channel steel entirety.
The present invention exempts from having the beneficial effect that for branch die combination purlin and its construction method：
By the way that a pair of of channel steel is arranged, it is set both to have formd the steel form for pouring concrete structure, further through split bolt and concrete knot
Structure connects, and achievees the effect that enhance purlin rigidity.
The present invention has been described in detail with reference to the accompanying drawings, those skilled in the art can be according to upper
