Abstract
The invention discloses an anchorage system for stabilizing a construction trestle. An anchor is of an inverted asymmetric U-shaped structure, and a U-shaped hanger ring is pre-embedded in the top of the anchor; an anchor main body is formed at one corner of the bottom of the anchor, and the anchor main body is obtuse; the other corner of the bottom of the anchor is a cutting curb, and the cutting curb is sharp; an anchor lug is pre-embedded between the cutting curb and the top of the anchor, and is connected with an anchor chain; steel wire ropes are symmetrically arranged at the two sides of the trestle, and connected with the trestle by winding and anchoring; the steel wire ropes are connected with the anchor lugs of the anchor through the anchor chain, and the anchor chain is connected with the anchor lugs and the steel wire ropes through snap buckles; the anchor is fixedly arranged on the ground.
Description
Technical field
The invention belongs to bridge traffic engineering technical field, be specifically related to a kind of anchorage system for stable trestle.
Background technology
Trestle is in civil engineering, and be transporting material, equipment, personnel and the temporary bridge facility built, be divided into timber trestle bridge and steel trestle by the material adopted, the bridge floor position of trestle generally determined according to constructed structure structure size and locus.The trestle that bridge floor position is higher, expose pile drift comparatively large, bridge floor passes through or operation easily causes rocking of trestle or topples, and brings serious potential safety hazard to the safety of constructor.
Summary of the invention
The object of this invention is to provide a kind of anchorage system for stable construction bridge, to ensure that bridge floor passes through and construction safety.
For achieving the above object, the technical solution adopted in the present invention is a kind of anchorage system for stable trestle, and this system comprises anchorage 1, anchor chain 2, wire rope 3, trestle 4, and anchorage 1 comprises anchorage main body 1.1, sword pin 1.2, cat ear 1.3, suspension ring 1.4.
Specifically, described anchorage 1 is inverted asymmetric U-shaped structure, and its top is embedded with U-shaped suspension ring 1.4.One jiao, the bottom of anchorage 1 is anchorage main body 1.1, and anchorage main body 1.1 is obtuse angle, plays counterweight effect; Another angle, the bottom of anchorage 1 is sword pin 1.2, and sword pin 1.2 is acute angle, the surface of sword pin 1.2 by prefabricated, polish, inlay the modes such as high-abrasive material and make it sharp, in anchor chain 2 tensioning process, play acting on grabbing.Be embedded with cat ear 1.3 between the sword pin 1.2 of anchorage 1 and the top of anchorage 1, cat ear 1.3 is connected with anchor chain 2.
Trestle 4 bilateral symmetry is provided with wire rope 3, and wire rope 3 is connected with trestle 4 by winding, ground tackle form, makes trestle 4 stress balance; Described wire rope 3 is connected with the cat ear 1.3 of anchorage 1 by anchor chain 2, and anchor chain 2 is connected by buckle with cat ear 1.3, wire rope 3; Anchorage 1 fixes on the ground; Make its tensioning by symmetry adjustment both sides anchor chain 2, reach the object of anchoring and final and trestle 4 forms rock-steady structure.
The material of described anchorage 1 is steel concrete or metal.
Compared with prior art, the present invention has the following advantages.
Present invention efficiently solves due to trestle bottom pile that to have length by oneself comparatively large, trestle passes through or and shortcoming that cause trestle rock and topple excessive due to moment in operation process.Owing to arranging one or multi-channel anchorage system respectively in trestle both sides, by the tensioning of anchor chain, anchorage system and trestle form statically-indeterminate structure jointly, finally reach the effect of stable trestle.Anchorage system can be applicable to the construction bridge under rivers or usual terms.

Detailed description of the invention
As shown in Figure 1-2, a kind of anchorage system for stable trestle, this system comprises anchorage 1, anchor chain 2, wire rope 3, trestle 4, and anchorage 1 comprises anchorage main body 1.1, sword pin 1.2, cat ear 1.3, suspension ring 1.4.
Specifically, described anchorage 1 is inverted asymmetric U-shaped structure, and its top is embedded with U-shaped suspension ring 1.4.One jiao, the bottom of anchorage 1 is anchorage main body 1.1, and anchorage main body 1.1 is obtuse angle, plays counterweight effect; Another angle, the bottom of anchorage 1 is sword pin 1.2, and sword pin 1.2 is acute angle, the surface of sword pin 1.2 by prefabricated, polish, inlay the modes such as high-abrasive material and make it sharp, in anchor chain 2 tensioning process, play acting on grabbing.Be embedded with cat ear 1.3 between the sword pin 1.2 of anchorage 1 and the top of anchorage 1, cat ear 1.3 is connected with anchor chain 2.
Trestle 4 bilateral symmetry is provided with wire rope 3, and wire rope 3 is connected with trestle 4 by winding, ground tackle form, makes trestle 4 stress balance; Described wire rope 3 is connected with the cat ear 1.3 of anchorage 1 by anchor chain 2, and anchor chain 2 is connected by buckle with cat ear 1.3, wire rope 3; Anchorage 1 fixes on the ground; Make its tensioning by symmetry adjustment both sides anchor chain 2, reach the object of anchoring and final and trestle 4 forms rock-steady structure.
The material of described anchorage 1 is steel concrete or metal.
Embodiment one
For the trestle at rivers place, prefabricated anchorage is transported to assigned address by barge, crane barge, slowly transfers at the bottom of rivers, then connects anchor chain, wire rope and trestle, reach anchoring effect.
Embodiment two
For the trestle in anhydrous location, can directly carry out prefabricated at assigned address to anchorage, after treating that anchorage reaches design strength, be connected with trestle with wire rope by anchor chain, reach anchoring effect.
