The side that the end of presstressed reinforcing steel is fixed on to end fixed part is set, by presstressed reinforcing steel by being penetrated in presstressed reinforcing steel through-hole, and is led to
Cross the direction of guide part control presstressed reinforcing steel.
Further, it is machined with one group of adjustment hole on the steering block, internal thread is machined with inside the adjustment hole, it is described
Internal thread is mutually matched with the external screw thread on the screw rod；By being machined with the internal thread coordinated with screw rod in adjustment hole, when
Rotated by tool drives screw rod or manual actuation screw rod rotate when, steering block is directly driven by screw thread matching relationship and is existed
It is moved up and down on screw rod.
Further, the screw rod lower end is processed as hexagonal prisms；Hexagonal prisms, adjusting easy to use are processed into screw rod lower end
Tool drives screw rod rotates.
Further, the spacing between every two pieces of billets is the half of the CLT plates width.
The present invention has the advantages that compared with the existing technology：
The present invention by by CLT plates, presstressed reinforcing steel, falling quadrangular pyramid, string device and anchor, to form prestressing force adjustable
Adjustment means；A string device for component is a kind of novel prestressing force regulation device, is realized to presstressed reinforcing steel by the device
Tensioning and regulation and control, ensure that CLT plates can realize that total cross-section is pressurized, make full use of material, increase the span of CLT plates and applicable model
It encloses；
The present invention makes full use of the compression strength of CLT plates and the tensile strength of presstressed reinforcing steel, increase CLT plates span and
The scope of application.
