Abstract
A kind of embedded junction box being applied to architecture advances in concrete precast floor, comprise the box body (1) of terminal box, four limits on box body (1) top form frame (11), the bottom surface of box body (1) forms the first through wires hole (13), the sidewall of box body (1) surrounding forms the second through wires hole (12), box body (1) lateral wall of the second through wires hole (12) upper and lower sides forms the groove (14) of some levels, the strip projection (15) of level is formed between the groove (14) of the second through wires hole (12) upside.It has set up bar shaped projection as supporting and groove, enhance and cohesive force between concrete therefore, it is possible to provide enough resistances, prevent terminal box from producing relative displacement, thus avoid embedded junction box place to occur the phenomenon of leaking.
Description
Technical field:
The utility model relates to the technical field of architectural engineering built-in fitting, more specifically to a kind of embedded junction box being applied to architecture advances in concrete precast floor.
Background technology:
When current concrete precast floor, wallboard, can more pre-buried terminal boxes, hydroelectric line.After concrete precast floor has been built, on transport, lifting or floor in assembling reinforcement process, terminal box can be collided or be trampled, thus causes between terminal box and concrete and occur tiny space.
And plastic junction box surface traditional is at present very smooth, smaller with concrete cohesive force, easily produce slip by under External Force Acting, thus the space formed between embedded junction box and concrete easily causes leaking.
Utility model content:
The purpose of this utility model is exactly the deficiency for conventional electrical connectors design, and provides a kind of embedded junction box being applied to architecture advances in concrete precast floor, and it efficiently solves the defect existing for conventional electrical connectors, prevents terminal box from producing relative displacement.
Technology solution of the present utility model is as follows:
A kind of embedded junction box being applied to architecture advances in concrete precast floor, comprise the box of terminal box, four limits of box body bottom form frame, the end face of box body forms the first through wires hole, the sidewall of box body surrounding forms the second through wires hole, the box body lateral wall of the second through wires hole upper and lower sides forms the groove of some levels, between the groove on the downside of the second through wires hole, form the strip projection of level.
Each sidewall of described box body forms two the second through wires holes, two the second through wires holes are distributed horizontally on box body.
Described strip projection is provided with 2, spacing between strip projection upper surface and frame is less than the thickness of precast floor slab, strip projection is molded on the relative lateral wall of box body one group, box body another organize on relative lateral wall and form preformed hole, preformed hole is between box body groove bottom and frame.
The beneficial effects of the utility model are:
It has set up bar shaped projection as supporting and groove, enhances and cohesive force between concrete thus can provide enough resistances, prevents terminal box from producing relative displacement, thus avoid embedded junction box place to occur the phenomenon of leaking.
Accompanying drawing illustrates:
Fig. 1 is the structural representation that the utility model is faced;
Fig. 2 is the structural representation of the utility model side-looking;
Fig. 3 is the structural representation that the utility model is overlooked.
In figure: 1, box body; 11, frame; 12, the second through wires hole; 13, the first through wires hole; 14, groove; 15, strip projection; 16, preformed hole.
Embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of embedded junction box being applied to architecture advances in concrete precast floor, comprise the box body 1 of terminal box, four limits of box body 1 bottom form frame 11, the end face of box body 1 forms the first through wires hole 13, the strip projection 15 of level is formed between groove 14 on the downside of groove 14, second through wires hole 12 box body 1 lateral wall sidewall of box body 1 surrounding forming the second through wires hole 12, second through wires hole 12 upper and lower sides forming some levels.
Each sidewall of described box body 1 forms two the second through wires holes, 12, two the second through wires holes 12 to be distributed horizontally on box body 1.
Described strip projection 15 is provided with 2, spacing between strip projection 15 upper surface and frame 11 is less than the thickness of precast floor slab, strip projection 15 is molded on the relative lateral wall of box body 1 one groups, box body 1 another organize on relative lateral wall and form preformed hole 16, preformed hole 16 is between box body 1 groove 14 bottom and frame 11.
Operation principle: the embedded junction box of this Curve guide impeller, it is by box body 1 being set up strip projection 15 and groove 14, and strip projection 15 uses as support, and strip projection 15 and groove 14 make the cohesive force between terminal box and concrete greatly improve.When terminal box is by External Force Acting, support and the cohesive force between groove 14 and concrete will provide enough resistances, prevent terminal box from producing relative displacement, thus avoid embedded junction box place to occur the phenomenon of leaking.
