Abstract
The utility model provides a kind of precast concrete box-frame, including；Concrete frame, and the top of frame, bottom have recess, recess can be used for the laying of pipeline.The precast concrete box shell of the utility model reduces when can be realized the installation of distribution box shell and cuts brick, avoids fugitive dust, wall damaged, and when repairing prevents hollowing, is greatly improved installation effectiveness, the energy conservation and environmental protection of distribution box shell.
Description
Technical field
The utility model relates to the technical fields of electrical installation project.It can ensure to exempt to chisel when the installation of distribution box shell, week
While guaranteeing the integrality of wall without hollowing.Distribution box shell installation quality and efficiency are specifically improved, green construction, section are reached
The effect of energy environmental protection.
Background technique
Distribution box is generally divided into bright dress and concealed installation according to the installation method.Usually box shell pedestal is fixed in structure when concealed installation.
In common residential houses engineering, box shell can be mounted in wall, box shell periphery is repaired with cement sand-lime.
The prior art generallys use following two mode in distribution box shell when filling is installed within the walls；
(1) brick method is cut after
After cut brick method be filling wall build complete after, according to the size and designed elevation of distribution box shell, chiselled, directly
To the installation requirement for completing distribution box shell.
(2) case position method is reserved
When reserved case position is building construction, cabinet is carried out according to distribution box size and is reserved, case position top disposes lintel, box shell
Periphery is repaired using sand-lime when installation.
However, above two method is both needed to carry out secondary construction, the duplication of labour, therefore have the disadvantage that
(1) it after filling wall is completed, is chiselled, fugitive dust is more during chiselling, and destroys wall body structure, and repairing is beaten
It is big to dig manpower consumption amount.
(2) reserving cabinet has certain randomness, not manageability, easily burst or position inaccuracy, after cabinet installation
Repaired using sand-lime, periphery can occur hollowing, cracking, infiltration phenomena such as.
Utility model content
In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide one kind can precast concrete case
Frame.He can ensure to exempt to chisel when box shell installation, reduce wall plastering hollowing, and distribution box shell simple to install, significant increase
Distribution box shell installation effectiveness and work quality.
In order to achieve the above objects and other related objects, the utility model one kind is provided can precast concrete box-frame, comprising:
Precast concrete outline border, size and distribution box bottom case including outline border are matched；
Oblong notches are reserved on concrete outline border；
Further, precast concrete box-frame is poured using C20 strength concrete.
Precast concrete box-frame can match the size of distribution box shell.
Precast concrete box-frame locates reserved distribution box pipeline recess up and down.
Precast concrete box-frame is integrally formed.
Precast concrete box-frame is square or rectangle.
As described above, the utility model can precast concrete box-frame, have the advantages that
(1) it is chiselled without cutting, it is environmentally protective, it is energy-saving；
(2) simple, box shell is installed securely, there is good practicability.
(3) box shell periphery without gaul, flake, crack phenomena such as.
Detailed description of the invention
What Fig. 1 was shown as the utility model can precast concrete box-frame and distribution box shell scheme of installation.
Fig. 2 be shown as the utility model can precast concrete box-frame structural schematic diagram.
In figure: 1- precast concrete box-frame, 11- oblong notches, 22- distribution box shell, 33- spool, 331- cement mortar
Fill area, 44- fill wall building block
Specific embodiment
Illustrate the embodiments of the present invention below by way of specific specific example, it should be noted that the present embodiment
Provided in diagram only illustrate the basic conception of the utility model in a schematic way, only display and the utility model in schema then
In related component rather than component count, shape and size when according to actual implementation draw, when actual implementation each component
Kenel, quantity and ratio can arbitrarily change for one kind, and its assembly layout kenel may also be increasingly complex.
Fig. 1 be embodiment in scheme of installation, Fig. 2 be can precast concrete box-frame structural schematic diagram.Mainly by 1-
Precast concrete box-frame, 11- oblong notches, 22- distribution box shell, 33- spool, 331- cement mortar fill area, 44- fill wall
Building block composition.Distribution box shell is inserted into inside box-frame, and periphery is blocked with cement mortar.
The precast concrete box-frame of the utility model is further described below by specific implementation case.In the embodiment
In, distribution box shell is installed using following steps:
(1) according to design requirement and distribution box shell material sample, citing distribution box enclosure is 20*30*12cm, wide 20cm,
High 30cm, depth 12cm.If preparing dry setting steel mold, each lattice inner edge are as follows: 25cm*35cm*12cm, periphery are as follows:
35cm*45cm*12cm, with a thickness of 5cm.
(2) it is moved towards according to spool, the recess of 10cm*6cm is reserved on mold (see Figure of description 1).
(3) after mold fastening, binding structure reinforcing bar and with C20 pea gravel concreten, immersion vibrator, which pours, to be smash, and is sufficiently vibrated
It is closely knit extremely to stop sinking.
(4) start to conserve in 12 hours after casting and compacting of concrete is complete, maintenance uses water seasoning.
So far, the production of precast concrete box-frame is completed.To ensure that concrete box-frame is placed accurately, using BIM technology
Carry out brick typesetting, coordinate setting box-frame position.After positioning, when masonry and concrete box-frame one-off construction.
A: distribution box shell is installed to inside concrete box-frame and fixes.
B: box shell periphery filled 1:1 cement mortar and carries out filleting processing after limit, through 36 hours defects liability periods.
C: the secondary piping work of distribution box is completed.
Finally, it completes and distribution box shell is installed by concrete box-frame, complete the overall process of secondary piping.
In conclusion the concrete box-frame of the utility model can be realized the installation of distribution box shell, secondary piping conveniently, it is not necessarily to
It chisels, greatly improves distribution box shell and secondary piping installation effectiveness；Cost is relatively low, repairing is without hollowing, infiltration, guarantees wall
Globality has good practicability.So the utility model effectively overcomes various shortcoming in the prior art and has height
Industry utility value.
