Description
Technical field
The present invention relates to a kind of concrete wall direct-burried switch box construction technique, dependent territory builds construction technology technology
Field.
Background technology
At present in constructure construction procedure is carried out, for convenience in later stage building supply line arrangement, often need
The switch box of distribution system is installed on wall in advance when building wall body construction is carried out, in traditional construction
During, often according to the architectural feature of the switch box installed, wall construction is carried out first, and will match somebody with somebody in construction
Hole is installed at the reserved place of the installation site of electric switch case, treats to carry out the installation of switch box, this side after the completion of wall construction again
Although the need for method can meet construction, always being found in practice of construction, the construction technology of this form of construction work is complex, applies
Work operating efficiency is low, and material loss is larger, and needs to carry out multiple reserving hole masterplate installing/dismountings, reserving hole later stage
The operation such as fill up, so as to significantly increase labour intensity and material loss, and be also easily caused after switch box installation it
Periphery is poor with being tightly combined property of wall, so as to cause wall outlet inanition to come off or seminess, on the one hand has a strong impact on and matches somebody with somebody
The stability and security of electric switch case operation, structural strength and aesthetic property of the another aspect also to wall cause serious harm,
Therefore this present situation is directed to, in the urgent need to developing a kind of brand-new concrete wall direct-burried switch box construction technique,
With meet it is actually used the need for.
The content of the invention
A kind of concrete wall direct-burried switch box construction technique is provided it is an object of the invention to provide the present invention.
In order to achieve the above object, the present invention provides following technical scheme：
A kind of concrete wall direct-burried switch box construction technique, comprises the following steps：
The first step, concealed installation panel switches box body processing, dimension is selected according to layout design pipeline specification model
Switch box, and cable-through hole of being slotted on the wall of switch box side, are then sealed cable-through hole with elastic packing plug, and
Reinforcing bearing rib is set in switch box, each side surface of switch box is supported calmly by strengthening bearing rib
Position, after completing reinforcing bearing rib installation positioning, separately in one layer of machine oil of switch box inner surface brushing, and in switch box
Interior filling such as sawdust, is then shut off switch box chamber door and switch box chamber door is sealed with corresponding template, and
Template sealing part is another by rubber belt sealing；
Second step, wall steel bar colligation is tied up according to the requirement of civil engineering wall inclination to the arrangement of reinforcement in wall；
3rd step, the line of setting structure 50 on the good shear force wall reinforcing steel bar of basic colligation, determines that the line of structure 50 is identified, then use
Level meter, guides at the indoor case of concealed installation, carries out the mark of 50 lines, and determine switch box with 50 lines from 50 line positions of fixed point
Corresponding position location；

Position is adjusted, and constitutes switch box installation hole, when reinforcing bar adjustment is carried out, makes reinforced steel bar ring around panel switches box body
Installation site be distributed, and reinforced steel bar ring around panel switches casing installation site be distributed when, reinforcing bar use detour and must not cut；
6th step, trimming bar is reinforced, in the inner side of the panel switches casing installation hole for determining, using reinforced concrete-bar
Hole was reinforced at least one week around hole；
7th step, trimming bar cutting, according to switch box physical dimension, will use cutting equipment for reinforcing
Hole height eminence panel switches box body up to lacks 5mm after cutting rest and reorganization, and rest and reorganization are carried out to reinforcing bar；
8th step, casing cable-through hole pipe arrangement, according to building supply line layout requirements, by penetration pipe and switch box
Cable-through hole is attached；
9th step, casing fixed installation, panel switches box body is installed to according to design height reserved with establishing by cable
Case is closed to install in hole, and after switch box casing is rectified, surrounding steel bar clamping, must not be with steel bar welding in wall
Connect, simultaneously, the spacer bar of welding one and wall uniform thickness at least three jiaos of panel switches box body, spacer bar is welded
It is connected on casing fixture, and spacer bar one end will flush and absolute upright with casing vertical plane, then will be with distribution box
The penetration pipe of casing connection is connected and fastens with casing, and penetration pipe enters straight at carton and crate, and exposed length is small in carton and crate
In 5mm；
Tenth step, shuttering casting concrete after switch box installation, mould is set at switch box panel
Plate, and template is offseted with switch box panel, concreting operation is then carried out to wall, and carry out concreting
During operation, concrete is poured from panel switches box body both sides, and not handy vibrating head is to week around distribution box body and casing
While carrying out directly vibrating operation.
11st step, switch box assembling pours operation, and after after concrete setting, incite somebody to action walls concrete is completed
The form removable of switch box, and the sawdust in switch box and reinforcing bearing rib are removed, then electrically set
It is standby to install.
Further, cable-through hole hole back gauge casing Edge Distance is not more than 10mm in the described first step.
Further, if the reinforced concrete-bar in reinforcing bearing rib and the 6th step in the described first step has cross-distribution
During situation, then it is attached with metal binding silk at its position of intersecting point.
Further, thickness of wall body is not less than 180mm.
The more traditional construction technology of construction technology of the present invention, can greatly reduce civil engineering structure hole to be provided, reduction hole and tear open
Mould is constructed, and effectively overcomes the easy outlet inanition phenomenon of conventional electrical distribution switch-box periphery wall, is reduced the stifled hole of civil engineering and is made
Industry amount and wall seminess, so as on the one hand simplify construction technology, are favorably improved the peace to the casing of switch box
Dress alignment quality and electrical equipment are installed and operation stability, are favorably improved electrical safety, improve wall impression quality, separately
One side can effectively improve efficiency of construction, and reduce labour intensity and material loss in construction, thus it is effective cost-effective,
Greatly reduce construction costs.
