In the example shown, suspension elements 30,42 include that the main body 72 of the centre of ledge surface 66 is arranged in.72 structure of main body
It makes to separate channel component 32,34.Main body 72 is shown as including hole 74, so as to receive to fixed suspension elements 30,
42 bolt relative to the lengthwise position of overhead 12.As shown, channel component 32,34 can respectively include along its length
The array in the hole of extension, in order to provide multiple tie points for suspension elements 30,42.
The second aspect of present disclosure is related to tommyhead bolt fastener.No. 6,059,258 United States Patent (USP) describes routine
The structure and function of tommyhead bolt fastener, entire contents are incorporated herein by reference.
Referring to Fig.1 0, the example of fastener assembly is generally shown with appended drawing reference 100.In the example shown, fastener
Component 100 includes bolt 102, clamping component 104, biasing member 106, washer 108 and nut 110.Bolt 102 is shown as
Head 112 and threaded body 114.Clamping component 104 is shown as including inside portion 116, opposite outside portion 118 and in inside portion
The hole 120 of clamping component 104 is extended through between 116 and outside portion 118, along axially bored line 122.
Fastener assembly 100 is assembled as shown in Figure 11 A, Figure 11 B and Figure 11 C.1A, Figure 11 B and Figure 11 C referring to Fig.1
(and with continued reference to Figure 10), head 112 is located at the inside portion 116 of clamping component 104, and body portion 114 extends through via hole
120.In the example shown, bolt 102 can along axially bored line 122 relative to clamping component 104 in retracted position and forward position
Between slide, in retracted position, head 112 is closest to inside portion 116, and in forward position, head 112 is separated with inside portion 116.
Nut 110 is threadedly coupled in the body portion 114 of bolt 102 at the outside portion of clamping component 104 118.Biasing member 106 and pad
Circle 108 is arranged between clamping component 104 and nut 110, so that bolt 102 is biased to retracted position.In the example shown, partially
Set the form that component 106 takes spring.
2, Figure 13 A and Figure 13 B referring to Fig.1, show fastener assembly 100 in conjunction with siding track 124.Siding track 124 includes opening
126,126 length of being open is far longer than its width.The width on head 112 is less than the width of opening 126, and length is greater than opening
126 width.It will be understood that when fastener assembly 100 is in and unlocks engagement (Figure 13 A), head 112 in this state
Length be aligned with the length of opening 126, head 112 can advance so as in insertion opening 126, and can retract so as to from
It is removed in opening 126.In forward position, bolt 102 can relative to clamping component 104 around axially bored line 122 rotate about 90 °,
To convert unlocking to engage and be engaged by locking between (Figure 13 B), when in being engaged by locking, head 112 is in siding track 124
The overlapping internal edge 128 of 126 surrounding of opening engagement so that the head 112 forced to move of biasing member 106 is against siding track 124, thus
Fastener assembly 100 is fixed to siding track 124.Therefore, fastener assembly 100 can rapidly and easily be fixed to siding track 124.
4 and Figure 15 referring to Fig.1 is shown tightly in conjunction with siding track 124 with the diagonal brace leg 130 with multiple tommyhead bolt channels 132
Fastener components 100.The purpose of fastener assembly 100 is that diagonal brace leg 130 is attached to siding track 124, to be attached to entire mould
Leg and beam (ledger) are thus rapidly and easily converted to braced frame by block beam, and vice versa, turns frame
It is changed to the leg that can be used as cross-brace.
Equally, the width on head 112 is less than the opening width in tommyhead bolt channel 132, and its length is greater than opening width
And it is less than the inner width in tommyhead bolt channel.In forward position, bolt 102 can be relative to clamping component 104 around axially bored line
122 rotations, to engagement and convert between being engaged by locking unlocking, under the engagement state that unlocks, head 112 can be with
Opening 126 across siding track 124 is inserted into tommyhead bolt channel 132, and under the state that is engaged by locking, head 112 engages tommyhead bolt
The internal edge in channel 132 so that biasing member 106 in a first direction on 134 head 112 forced to move against T bolt channels 132,
And clamping component 104 forced to move is against siding track 124 in the second direction 136 opposite with first direction 134, thus by siding track 124
It is fixed together with tommyhead bolt channel 132.Therefore, fastener assembly 100 can be used for siding track 124 and T shape rapidly and easily
Bolt channels 132 are fixed together.
Although foregoing description provide the examples of one or more device or method, it is to be understood that, other devices or side
Method can be within the purview of the appended claims.
