Description

A kind of built-in fitting

Technical field

The present invention relates to Architectural Equipment, particularly to a kind of built-in fitting。

Background technology

Road both sides is typically provided with signal lights, monitoring, street lamp and road traffic direction board, it is all fixing by being erected at the carrying of the rod member of road both sides, these rod members to be also erected at roadside for a long time, period also suffers high wind and the artificial risk clashed into, the effectively fixing key factor being to ensure the trip of road travel, pedestrains safety to rod member。Usually first install built-in fitting in precalculated position, built-in fitting is placed in foundation ditch, then casting concrete, and the pre-buried bar upper end of built-in fitting is exposed, and upper end is provided with screw thread, and then the bottom of rod member is bolted on the upper end of pre-buried bar。

At present, mostly built-in fitting is directly to be welded, and its structure is fixed, and volume can not change, and therefore when depositing and transporting, owing to shape is fixed, takes up room big, therefore deposits quantity in the confined space and single transport quantity is extremely limited。Waste parking space, increase cost of transportation, virtually add input。And welding process requires higher for the technology of workman, position, angle between its structure member are wayward, it is necessary to the auxiliary operations such as fixture, therefore complex process, relatively costly, because the technical quality of workman is different, the built-in fitting produced also can cause that quality is uneven。

Summary of the invention

In order to overcome drawbacks described above, the invention provides a kind of built-in fitting, simple in construction, easy for installation, owing to splitting, therefore occupation of land space is greatly reduced, and transports also convenient。

The present invention is achieved through the following technical solutions:

A kind of built-in fitting, it is provided with externally threaded pre-buried bar including four upper ends, every pre-buried bar connects each through the fixture of two frame structures, described fixture is horizontally disposed with and parallel to each other, two fixtures lay respectively at the upper and lower of pre-buried bar, four drift angles of fixture are respectively equipped with the partition of annular, the internal diameter of partition is equal to the diameter of pre-buried bar, pre-buried bar passes from partition central authorities, pre-buried bar lower surface is provided with and stops the projection being positioned on the fixture of pre-buried bar bottom partition and gliding, the upper end of pre-buried bar is provided with the bolt of fixing partition, on pre-buried bar, the part between the partition of upper and lower two fixtures is provided with sleeve, sleeve is provided with some through holes, the external diameter of sleeve is less than the external diameter of partition。

The partition that described fixture is adjacent connects by metal tube is fixing。Fixture has at least a partition being pointed to diagonal position to connect by metal tube is fixing。Fixture has a partition being pointed to diagonal position to connect by metal tube is fixing。The metal tube that the partition of the diagonal position of two fixtures up and down on pre-buried bar connects in opposite direction。

Through hole on described sleeve is provided with two, and through hole general perspective is rectangular。Through hole lays respectively at the upper and lower of sleeve, and in angular distribution。

One section of bending of the close bottom of described pre-buried bar。

Beneficial effects of the present invention:

Compared with prior art, one is simple in construction to the present invention, it is not necessary to welding sequence, and therefore cost reduces；Two is to split, and occupation of land space is little, deposits and convenient transportation；Three is pre-buried bar, fixture can by a certain size, model batch production, and the volume size of the same size of mounted built-in fitting is completely the same, and anthropic factor when being greatly reduced installation of embedded parts affects its total quality。

Detailed description of the invention

As shown in Figure 1, the present invention includes four upper ends and is provided with the pre-buried bar 1 of external screw thread 2, every pre-buried bar 1 connects each through the fixture 3 of two frame structures, and described fixture 3 is horizontally disposed with and parallel to each other, and two fixtures 3 lay respectively at the upper and lower of pre-buried bar 1。

As in figure 2 it is shown, the four of fixture 3 drift angles are respectively equipped with annular partition 4, the internal diameter of partition 4 is equal to the diameter of pre-buried bar 1。Pre-buried bar 1 passes from partition 4 central authorities。

The partition 4 that fixture 3 is adjacent connects by metal tube 7 is fixing。

Described fixture 3 has at least a partition 4 being pointed to diagonal position to connect by metal tube 7 is fixing。In the present embodiment, fixture 3 has a partition 4 being pointed to diagonal position to connect by metal tube 7 is fixing。

In order to increase integrally-built stability, as it is shown in figure 1, in the present embodiment, the metal tube 7 that the partition 4 of the diagonal position of two fixtures 3 up and down on described pre-buried bar 1 connects in opposite direction, its downward projection crosses one another。

As shown in Figure 3, lower surface at pre-buried bar 1 is provided with and stops the projection 5 being positioned on the fixture of pre-buried bar bottom partition 4 and gliding, the upper end of pre-buried bar 1 is provided with the bolt 6 of fixing partition 4, and one section of bending of the close bottom of pre-buried bar 1, increase the resistance to tension of pre-buried bar 1 with this。

On pre-buried bar 1, the part between the partition 4 of upper and lower two fixtures 3 is provided with sleeve 8, and sleeve 8 is provided with some through holes 9, it is simple to concrete flows in sleeve 8, fills up the space between sleeve 8 and pre-buried bar 1, it is prevented that rock。In order to make partition 4 can carry sleeve 8, the external diameter of sleeve 8 is less than the external diameter of partition 4。

In order to allow concrete quickly fill, as shown in Figure 4, in the present embodiment, the through hole 9 on sleeve 8 is provided with two, and through hole 9 general perspective is rectangular。Through hole 9 lays respectively at the upper and lower of sleeve 8, and in angular distribution, it is simple to concrete flows and air-out in sleeve 8, it is prevented that air trapping and there is space。

Implement, in installation process, pre-buried bar 1 first to pass through one of four partitions 4 on fixture 3 one by one, is moved to pre-buried bar 4 bottom by this fixture 3, being stopped by projection 5 to partition 4。Then sleeve 8 is enclosed within one by one on pre-buried bar 4, then again another fixture 3 is installed through the mode of its partition 4 one by one by pre-buried bar 1, the partition 4 of this fixture 3 is blocked in the top of pre-buried bar 1 by sleeve 8, and metal tube 7 downward projection noted during installation on the diagonal angle of upper and lower two fixtures 3 between partition 4 crosses one another。Finally, one by one the partition 4 of the fixture 3 on top is fixed by bolt 6。
