Problems solved by technology

This leads to the fact that the installation of anchors in the process of prestressed construction is entirely based on experience, and pre-clamping is performed by manpower, which makes it difficult to ensure the quantification of pre-clamping force and the accuracy of pre-clamping degree.

Embodiment 1

[0047] like figure 1 and figure 2 As shown, a clip-type anchorage pre-clamping device applied to FRP plates, the entire pre-clamping device except for the FRP plate to be clamped, mainly consists of a force transmission screw and a supporting nut 2, a sliding force transmission block 3, a pad Key components such as block 4, structural foundation or base 5a, jack 6 with digital code table and reaction force block 7 are formed.

[0048] The two force-transmitting screws 2 are arranged in parallel through the connecting through holes on the sliding force-transmitting block 3, the structural foundation or base 5a, and the counter-force block 7 in sequence, and the two ends are fastened with nuts, and the anchor head 1c to be clamped is built into the sliding Between the force transmission block 3, the structural foundation or base 5a, the jack 6 with a digital code meter is built between the structural foundation or base 5a, and the reaction force block 7, forming a closed force...

Embodiment 2

[0053] like image 3 and Figure 4 As shown, a clip-type anchor pre-clamping device applied to FRP tendons, the entire pre-clamping device except for the FRP tendons to be clamped, mainly consists of a force transmission screw and a supporting nut 2, a sliding force transmission block 3 , pad 4, jack 6 with digital code meter and reaction block 7 and other key components, the structural foundation or base part is omitted, and it is mainly used in temporary or construction sites where pre-clamping accuracy is not high.

[0054] The two force-transmitting screws 2 are arranged in parallel through the connecting through holes on the sliding force-transmitting block 3 and the counter-force block 7 in sequence, and the two ends are fastened with nuts, and the anchor head 1c to be clamped is built into the sliding force-transmitting block 3 and the spacer 4, a jack 6 with a digital code meter is built between the cushion block 4 and the counter force block 7, forming a closed force...

Embodiment 3

[0059] like Figure 5 and Image 6 As shown, a clip-type hinged anchor pre-clamping device applied to FRP plates, the entire pre-clamping device except for the FRP plate to be clamped, mainly consists of a force transmission screw and a supporting nut 2, a sliding force transmission block 3. It is composed of key components such as cushion block 4, temporary cement base 5a, jack 6 with digital code meter and counter force block 7; temporary cement base 5a is temporarily fastened on the flat cement base 8 by two long bolts ; The inner edge of the sliding force transmission block 3 is a concave arc surface, which forms a hinge structure with the outer convex arc surface of the inner edge of the hinged anchor head during the pre-clamping process.

Abstract

The invention discloses a pre-clamping device of a clamping piece type anchorage device for FRP. A sliding force transmission block and a counter-force block are connected through a force transmissionbolt; a to-be-clamped anchor head and a jack are arranged in the pre-clamping device; a clamping piece and a to-be-clamped material are evenly fed into a wedge-shaped through hole of the anchor headthrough tension of the jack; normal pressing is conducted on the clamping piece and the to-be-clamped material through the wedge-shaped through hole; quantitative control over the tension is achievedthrough an empirical formula and a digital code table arranged on the jack; and finally quantitative controllable pre-clamping of the whole anchor head is achieved. The anchor head pre-clamping deviceis wide in application range, light in size, simple to manufacture, easy to install, controllable in prestress quantification, reliable in performance and high in universality, local stress concentration of an anchoring system can be effectively reduced, the contact stability of the to-be-clamped material and the anchoring system is improved, the mechanical property of the material is brought into full play, and the clamping uniformity of various types of ribs, stranded wires, plates and profiles is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tensioning and anchoring of building materials, in particular to a pre-clamping device of a clip-type anchor for FRP. Background technique [0002] Prestressing technology is widely used in the construction and reinforcement maintenance of bridges, houses and special projects. Applying prestress to prestressed materials through tension requires an anchoring system with excellent performance. Currently, there are two main types of clamping or anchoring methods for prestressed materials: mechanical clamping and clip clamping. [0003] Clip-type clamping mainly uses clamping pieces and anchor bolts to compress and lock the prestressed material, and relies on mechanical force to achieve clamping. This structure is generally accepted by construction projects because of its simple design and reliable performance. Ordinary clip-type prestressed structures are composed of anchors at both ends, prestressed mater...
