Abstract
The utility model relates to that a kind of built-in sliding chute is fixing uses T-shaped bolt, and T-shaped bolt is made up of bolt head and screw rod; It is characterized in that: the end of described screw rod is square, when production section of jurisdiction, U-shaped beam, built-in sliding chute matches with T-shaped bolt, is fixed on shaping die with nut, build, after maintenance completes, when removing shaping die, do not need to remove the concrete on nut, only need block the square place of end of screw rod with spanner, slightly firmly rotate α, α=90 °, when the length direction of T-shaped threaded screw fasteners head is parallel with notch, take off T-shaped bolt.The downward projection face of described bolt head is parallelogram, and the width of bolt head is less than the width of built-in sliding chute notch, and the long limit size of bolt head is less than built-in sliding chute inner width.Bolt head and the built-in sliding chute surface of contact of T-shaped bolt have the miniature tooth matched with built-in sliding chute, and built-in sliding chute matches with T-shaped bolt, are fixed on shaping die with nut, and Tightening moment is 80Nm.
Description
Technical field
The utility model relates to a kind of T-shaped bolt, particularly relates to that a kind of built-in sliding chute is fixing uses T-shaped bolt.
Background technique
At present, a lot of with the matching used T-shaped bolt kind of built-in sliding chute, built-in sliding chute fixing on shaping die during for being embedded in connection and prefabricated pipe section, the U-shaped beam of the external member of the built-in sliding chute of section of jurisdiction, U-shaped beam, building concrete etc. in advance.When production section of jurisdiction, U-shaped beam, built-in sliding chute is bolted on shaping die by T-shaped, in concreting process, tightening nut is easily covered by concrete, when removing shaping die, need to unscrew T-shaped disassembling bolts after nut with spanner, concrete on such tightening nut will be removed totally, but difficulty removed by concrete, and the dismounting of completing aftershaping mould to section of jurisdiction, U-shaped beam like this brings inconvenience.
Model utility content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of easy-to-dismount T-shaped bolt.
To achieve these goals, the technical solution adopted in the utility model is: T-shaped bolt is made up of bolt head and screw rod; It is characterized in that: the end of described screw rod is square, when production section of jurisdiction, U-shaped beam, built-in sliding chute matches with T-shaped bolt, is fixed on shaping die with nut, build, after maintenance completes, when removing shaping die, do not need to remove the concrete on nut, only need block the square place of end of screw rod with spanner, slightly firmly rotate α, α=90 °, when the length direction of T-shaped threaded screw fasteners head is parallel with notch, take off T-shaped bolt.
The downward projection face of described bolt head is parallelogram, and the width of bolt head is less than the width of built-in sliding chute notch, and the long limit size of bolt head is less than built-in sliding chute inner width.
Bolt head and the built-in sliding chute surface of contact of T-shaped bolt have the miniature tooth matched with built-in sliding chute, and built-in sliding chute matches with T-shaped bolt, are fixed on shaping die with nut, and Tightening moment is 80Nm.
The utility model has the advantages that:
Build at section of jurisdiction, U-shaped beam, after maintenance completes, when removing shaping die, only need block the square place of end of screw rod with spanner, slightly firmly rotate, when the length direction of T-shaped bolt head is parallel with notch, T-shaped bolt can take off.Like this, when nut is covered by concrete, do not need to remove it, save artificial.
Accompanying drawing explanation
Fig. 1 is the structural representation of T-shaped bolt of the present utility model.
Fig. 2 is the connection diagram of T-shaped bolt and built-in sliding chute.
Fig. 3 is the dismounting schematic diagram of T-shaped bolt and built-in sliding chute.
Drawing reference numeral illustrates: 1-bolt head, 2-screw rod, 3-nut, 4-square end, 5-built-in sliding chute, 6-shaping die (the local signal of shaping die steel plate), α-rotation angle.
Embodiment
Be described in detail below in conjunction with Fig. 1-3 pairs of the technical solution of the utility model, but content of the present utility model is not limited thereto.
As Figure 1-3, T-shaped bolt is made up of bolt head 1 and screw rod 2; It is characterized in that: the end of described screw rod 2 is square; The downward projection face of described bolt head 1 is parallelogram, and the width W 2 of bolt head 1 is less than the width W 1 of built-in sliding chute 5 notch, and the long limit size V2 of bolt head 1 is less than built-in sliding chute inner width V1.When production section of jurisdiction, U-shaped beam, built-in sliding chute 5 matches with T-shaped bolt, is fixed on shaping die 6 with nut 3.Build, after maintenance completes, when removing shaping die 6, do not need to remove the concrete on nut 3, only need block the square end 4 of screw rod 2 with spanner, slightly firmly rotate α, α=90 °, when the length direction of T-shaped threaded screw fasteners head 1 is parallel with notch, take off T-shaped bolt.Like this, when nut is covered by concrete, do not need to remove it, save artificial.
Therefore the dismounting that the utility model is convenient to section of jurisdiction, U-shaped beam has produced aftershaping mould, saves time, manually.
Claims (3)
