Include following steps:
(1) precast plant make guardrail, guardrail bottom be equipped with a groove, the pre-buried 2 single u-shaped reinforcing bar of guardrail bottom,
It is equipped at slope at the top of guardrail and pours into mortar hole and slurry outlet；
(2) along the longitudinal equidistant pre-buried several groups U-shaped steel muscle in every side of two sides at the top of box beam, every group of U-shaped steel muscle is lateral
Comprising 2 single u-shaped reinforcing bars, the spacing of every group of 2 single u-shaped reinforcing bars is equal with the spacing of prefabricated guardrail U-shaped steel muscle；
(3) above-mentioned guardrail is positioned by lifting, takes guardrail bottom and one group of U-shaped steel muscle of box beam top side
Connect, at the gap that guardrail is contacted with box beam with waterproof material fill seal, U-shaped steel muscle lap-joint cross straight muscle nonfloating rail and
Box beam；
(4) groove of the mortar hole to U-shaped steel muscle lap-joint perfusion high-strength mortar filling guardrail bottom is poured into from guardrail, most
It is closely knit to grout outlet cleaning closing afterwards, complete the assembled connection construction of Bridge guardrail.
Preferably, the waterproof material at guardrail and box beam gap includes waterstop, silica gel with waterproof performance
Material, thus play the role of effective fit sealing, the leakage phenomenon for preventing subsequent mortar injection from generating.
Preferably, connecting between adjacent barrier using ribbet, cellular rubber mortar leakage prevention is pasted, easy to operate, safety
Reliably, the investment of temporary support and manpower is reduced, construction period is shortened.
The invention has the benefit that prefabricated components design is rationally simple, the production of industrial fast fast-growing may be implemented；Without scene
Casting concrete process flow, construction is simple；It is perfused using high-strength mortar, is convenient for quality management；The late maintaining time is short, is convenient for
Quickly use；Guardrail is prefabricated, can guarantee quality, accelerates speed of application, improves labor efficiency；Ribbet is used between adjacent barrier
Connection, after the completion of bridge construction, the construction of assembled connection guardrail can be rapidly completed in this method, realize building industrialization.

Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate this hair
It is bright, rather than limit the scope of protection of the present invention.What those skilled in the art made according to the present invention in practical applications changes
Into and adjustment, still fall within protection scope of the present invention.
In order to better illustrate the present invention, the present invention is described in detail below with attached drawing.
A kind of precast assembly guardrail construction connection method, includes the following steps:
(1) guardrail 1 is made in precast plant, guard bar structure is as shown in Figure 1, be equipped with a groove 8, guardrail in 1 bottom of guardrail
The pre-buried 2 single u-shaped reinforcing bar 2 in bottom is equipped at the top of the guardrail at slope and pours into mortar hole 6 and slurry outlet 7, above-mentioned to pour into mortar hole 6
With shown in 7 detail drawing of slurry outlet such as Fig. 6 (b), used to subsequent filling high-strength mortar；
(2) prefabricated box-beam structure is as shown in Fig. 2, every side along 5 top two sides of box beam is longitudinal equidistant pre-buried several
Group U-shaped steel muscle, every group of U-shaped steel muscle laterally includes 2 steel bars, and the spacing of every group of 2 single u-shaped reinforcing bars and prefabricated guardrail are U-shaped
The spacing of reinforcing bar is equal；
(3) when 1 intensity of guardrail reaches 80% or more, guardrail is transported to by construction site using transport vehicle, transport, lifting,
Guardrail must not be collided during installation guardrail, the protection of U-shaped steel muscle is especially paid attention to, lifts above-mentioned guardrail, as shown in figure 3, shield
The hoisting process on column mainly has a preparation suspender, and connection suspension centre, secure connection confirmation check, hangs liter, falls, aligns, entering position, correction
The processes such as position, stockyard personnel fix, and transport driver finally fixes when installing guardrail 1, first will contact surface treatment and put down under guardrail
It is whole, and mortar levelling, guardrail 1 and 5 junction of box beam is used to fill using waterstop, to play the work of effective fit sealing
With the leakage phenomenon for preventing subsequent mortar injection from generating；
After above-mentioned process inspection acceptance(check), straight muscle 3, as shown in Fig. 4 (a), detail drawing are inserted into U-shaped steel muscle lap-joint
As shown in Fig. 4 (b), since the quality of connection of prefabricated components is particularly important, internal various reinforcing bars should have material certificate or
Test report list guarantees the safety approval of reinforcing bar and other materials, which preferably uses novel high-quality alloy steel products, firm resistance to
Jail, rigid are better than twice of common iron, and after several years not aging, indeformable, non-corrosive, enhance guardrail uses the longevity
Life, it is therefore prevented that consumption wealth effort caused by the later period is replaced reduces cost, realizes sustainability；
Adjacent two guardrail is attached using ribbet, as shown in Fig. 6 (a), and pastes one layer of cellular rubber mortar leakage prevention；
(4) after above-mentioned steps acceptance(check), high-strength mortar is perfused to 2 lap-joint of U-shaped steel muscle from the mortar hole 6 that pours into of guardrail
The groove 8 of guardrail bottom is filled, the high-strength mortar has anti-permeability performance strong, and adhesive property is good, the strong feature of durability,
Without vibrating, add water and stir can be used at the scene, as shown in figure 5, in filling process, it should be clear by 7 mortar disintegrating slag of grout outlet
Reason is clean, and grout outlet closed it is closely knit, to complete the assembled connection construction of Bridge guardrail.
Present invention disclosed above preferred embodiment is only intended to help to illustrate the present invention.There is no detailed for preferred embodiment
All details are described, are not limited the invention to the specific embodiments described.Obviously, according to the content of this specification,
It can make many modifications and variations.These embodiments are chosen and specifically described to this specification, is in order to better explain the present invention
Principle and practical application, so that skilled artisan be enable to better understand and utilize the present invention.The present invention is only
It is limited by claims and its full scope and equivalent.
