Embodiment
Accompanying drawing is the utility model schematic diagram, by taking SS grades of guardrails of certain engineering as an example.
It is a kind of half prefabricated reinforced concrete wall fence as shown in Figure 1, it is characterised in that a part is to protect on the outside of guardrail
The form of column prefabricated concrete board 1 is prefabricated, the pre-buried stretching reinforcing bar in the inner side of guardrail prefabricated concrete board 1, chooses pre-buried in arm 2 with superstructure beam
Reinforcing bar part is welded or colligation, and hanging plate in place is required according to anti-collision wall line style, and link position is smeared and sets up internal model on the inside of slurry, guardrail
Plate, carries out concrete 3 on the inside of the cast of inner side concrete, prefabricated concrete board and cast-in-place guardrail and is collectively forming entirety.
Schematic diagram is by taking SS grades of reinforced guardrails as an example.
Installation site chooses arm sideline to inner side 350mm, outside 150mm, or other sizes.
SS grades of guardrail hanging plates are illustrated as Fig. 2 ~ 5 are shown in prefabricated concrete board structural map and hanging plate in steel bar arrangement figure, figure
Structure principle.
The outside profile of guardrail prefabricated concrete board 1 is consistent with guardrail profile, and thickness can be 65mm, or other sizes are located at
On the outside of guardrail, can as cast-in-place part outboard template；Side joint, which drips, in guardrail prefabricated concrete board sets hanging plate pedestal 4, pedestal chi at 5
Very little is 150mmx173mm（High x is wide）, or other sizes, the bottom of hanging plate pedestal 4 chooses arm top with beam and flushes, hanging plate pedestal 4
It act as making hanging plate be fixed on beam choosing on arm；Hanging plate bottom is drips 5, and 5 height of dripping are that outside chooses arm and highly adds 50mm, also may be used
For other sizes, the 5 width lower edges that drip are 100, and upper limb is 150mm, or other sizes, the lateral surface dripped be bottom to
The inclined inclined-plane in inner side, act as making rainwater flow out along lower end herein, without flowing to beam body.
Guardrail height is pave-load layer top surface level above, can be the armored concrete wall guardrail and group of specification defined
Any height of box-like guardrail concrete parts.
Hanging plate is highly：Guardrail height+pave-load layer thickness+drips highly
Hanging plate width is 1495mm, plate stitch 5mm, or other sizes are defined by easy construction.
It is illustrated in figure 3 the reinforcement drawing that SS grades of prefabricated concrete boards are illustrated in prefabricated concrete board reinforcement drawing, figure.11,12,14 in figure
Reinforcing bar is reinforcing bar in hanging plate, and four groups of reinforcing bars are stretched out under upper in the top of the guardrail prefabricated concrete board, wherein first group of reinforcing bar 13a
Including a less hollow reinforcing bar, hollow reinforcing bar side is provided with opening, opening outwardly, and two phases are presented in terms of outside
To the L-shaped reinforcing bar of setting, and form small gap between the two, hollow reinforcing bar opposite side is embedded in hanging plate in advance, and with hanging plate
Bar connecting；Second group of reinforcing bar 13b includes an arched door shape Ω steel bar, and outside is in arch door shape（Or referred to as circular arc）, Ω
The bipod of steel bar is embedded in hanging plate in advance, and with bar connecting in hanging plate, it is ensured that the anchorage length of reinforcing bar；3rd group of reinforcing bar
13c also includes a large mouth font reinforcing bar, and hollow reinforcing bar side is provided with opening, opening outwardly, presentation two in terms of outside
The L-shaped reinforcing bar that root is oppositely arranged, and form small gap between the two, hollow reinforcing bar opposite side is embedded in hanging plate in advance, and with extension
Bar connecting in plate；4th group of reinforcing bar 15 then includes a square frame-shaped reinforcing bar, and side is embedded in hanging plate in advance, and connects with reinforcing bar in hanging plate
Connect, second group of reinforcing bar 13b can be used as suspension ring reinforcing bar, embedded bar in arm is chosen by interim reinforcing bar 16 and superstructure beam and welded
Connect to form interim connection, embedded bar is welded in interim one end of reinforcing bar 16 and mat formation reinforcing bar or beam, the other end and second group of reinforcing bar
13b or other reinforcement weldings, the interim connection of composition, play a part of fixed hanging plate, the 4th group of reinforcing bar 15 is arranged at hanging plate pedestal
Top, and set close to hanging plate pedestal, the 4th group of reinforcing bar 15 chooses the welding of embedded bar 17 in arm with superstructure beam and forms permanent
Connection.
Such as Fig. 6 ~ 8 show guardrail construction process figure,
Step one：The construction of prefabricated concrete board is first completed, hanging plate is placed on superstructure beam and chosen on arm, by the 4th group of hanging plate
Reinforcing bar 15 chooses arm embedded bar with superstructure beam and welds to form permanently connected, separately by interim one end of reinforcing bar 16 and mat formation reinforcing bar or
Embedded bar is welded in beam, the other end and second group of reinforcing bar 13b or other reinforcement weldings, the interim connection of composition, and in hanging plate base
Seat bottom smears that cement mortar 6 is levelling, while playing and choosing arm cementation, a few road measures reliably connect hanging plate with choosing arm and being formed
Connect, fixed hanging plate.
Step 2：Side rail reinforcing bar in colligation, sets up concrete on the inside of inner side template 7, cast guardrail.
Step 3：After the concrete curing phase terminates, inner side template is removed, interim reinforcing bar 16 is removed, guardrail construction is completed.
The advantage of the prefabricated reinforced concrete wall fence construction technology of the utility model half is to change traditional guardrail
Form of construction work, the cast-in-place work of part field switchs to prefabrication completion, and outside is saved by the use of hanging plate as template when guardrail is constructed
Substantial amounts of template, only cast-in-place part concrete, shortens on-site construction time.Prefabricated concrete board plant produced, presentation quality is good,
Batch making is convenient, and scantling precision is guaranteed.Because member-retaining portion is cast-in-place, it is ensured that guardrail with choosing being reliably connected for arm,
Stress performance is good, good endurance.The risk of the live work high above the ground of workmen is reduced, on-site noise and dust pair is reduced
The influence on periphery.
