Description

Side wall anchored bearing and mounting method thereof

The present invention is about being provided with the anchoring part and the mounting method thereof of the anchor head (anchor) of prestressed steel tendon (wire rope) on sidewall paneling (web) that is arranged on the prestressed concrete structure or the base plate.

Prestressed concrete engineering since rose in 1940 be practical since, be applied to many large-scale prestressed reinforced concrete construction things.For example, the construction panels inside of the works of bridge, oil storage tank, cement storage bin, granary and so on sets the technology of prestress steel tendon, uses and utilizes this prestress steel tendon to bear deadweight and other loading of prestressed reinforced concrete construction thing when work progress.And after this prestressed reinforced concrete construction thing was finished, it added active forces such as load-carrying, live load and variations in temperature, and also major part is born by these prestress steel tendons.

Generally speaking, when setting the prestress steel tendon, the force side anchoring part of this prestressing force steel key is mounted in the both ends of works, yet under many special statuss, the force side anchoring part must be installed on the sidewall paneling (web) or base plate of works, just must on the sidewall paneling of works or base plate, construct again in addition this moment several from the outstanding concrete anchor ingot bar of sidewall paneling face or base plate face for installation force side anchoring part, for example: oil storage tank, the cement storage bin, the works of the drum of granary and so on needs annular prestressed and when desiring to set the prestress steel tendon in sidewall paneling inside, the concrete anchorage piece that must construct several concrete anchor ingot bars that are the pyrometric cone shape or cuboid shape on its sidewall paneling face comes for the force side anchoring part is installed.In addition, shown in the 1st figure, on the bridge that utilizes cantilevered frock method to construct, be to set various prestress steel tendons at position up and down to bear various mechanical loads, for example: the steel tendon that is disposed in box beam (Cell) top board is called top board steel tendon H (or claiming main steel tendon), when construction operation in bridge pier or the abutment Shi Zhushi that stretches out, promptly rely on this top board steel tendon burden cantilever position down the deadweight of beam body and construct in other loadings.In addition, be disposed at the end span outside and in the sidewall paneling (web) of span beam center bottom or acting as when be continuous state after the bridge closure of the base plate steel tendon L on the base plate (or claiming additional steel tendon), in order to the deadweight of beam body, loading, the variations in temperature alive of bearing part and add load-carrying etc.At this moment, the force side anchoring part of top board steel tendon H is mounted on the outside end face of box beam (Cell), and is therefore fairly simple in the construction that the force side anchoring part is installed, and do not constitute problem.But the force side anchoring part of base plate steel tendon L then is mounted on the sidewall paneling face of box beam, therefore must construct several concrete anchor ingot bars that are the pyrometric cone shape and come for the force side anchoring part is installed on this sidewall paneling face.

Construct in the engineering of bridge in the annular prestressed engineering of cylinder type thing and with cantilevered worker method, the force side anchoring part is installed on the sidewall paneling face is to take a lot of work very much and time-consuming job.Supply to install the force side anchoring part because must on the sidewall paneling face, construct the concrete anchor ingot bar that is the pyrometric cone shape in addition.Be commonly used to construct out the method for the concrete anchor ingot bar that is the pyrometric cone shape, be as shown in Figure 2, on the plate face of sidewall paneling W, the upright triangle taper reinforcing cage T who gives prominence to gradually towards the plate face outside along the long axis direction of this sidewall paneling W of elder generation's colligation group, inside in this triangle taper reinforcing cage T is embedded into: steel tendon sleeve pipe P, and be connected in this steel tendon anchoring part EA with the tail end of sleeve pipe P, and the coiled type spring EP (for the usefulness that relaxes tensile stress) that is sleeved on the outside of this anchoring part EA afterwards, again in the upright pyramidal template of triangle (not shown) that forms of this triangle taper reinforcing cage T outside group, then, carry out concrete perfusion and arrive template inside to form the concrete anchor ingot bar B of pyrometric cone shape.By the time after the concrete anchor ingot bar B of this pyrometric cone shape hardens fully, be fixed on the anchoring part EA just at the steel tendon inner dragline prestress steel tendon (not shown) of sleeve pipe P, and with the end of prestress steel tendon.

According in the past experience as can be known, when constructing bridge engineering with cantilevered worker method, need form box beam (Cell) the joint piece of the concrete anchor ingot bar B of pyrometric cone shape at sidewall paneling, need increase 1-2 working day in the engineering time aspect,, need form through the colligation groups are upright during outstanding gradually triangle taper reinforcing cage T towards the plate face outside along upright one of the long axis direction colligation group of the sidewall paneling W of this box beam (Cell) joint piece because desire by many reinforcing bar Tt and several not isometric vertical bar shape reinforcing bar Tx that are bent into the  font.Yet, each is bent into the reinforcing bar Tt of  font and the vertical bar shape reinforcing bar Tx difference because of the position that it disposed, the position of its length and bending is also inequality, so when tailoring these reinforcing bar materials, can't make in large quantities with same specification, to carry out all will tailoring reinforcing bar again and bending operation when the colligation group is found reinforcing cage, in the extreme trouble at every turn.Yet, the suitable masterful technique of need of work of the reinforcing cage of the upright pyrometric cone shape of colligation group on sidewall paneling not only, consuming time especially the taking a lot of work of work of founding out the pyramidal template of triangle organized in the reinforcing cage outside at the pyrometric cone shape again, and the cutting losing quantity of template is also big simultaneously.In addition, in order to form the concrete anchor ingot bar B of pyrometric cone shape, expend the concrete material of 1-2 stere again extraly, each side such as very uneconomical is all the problem that traditional technology is deposited.
