Description

Ceiling joist

Technical field

The utility model belongs to clean operating room in hospital accessory technical field, is related to a kind of ceiling joist.

Background technology

At present in clean operating room in hospital construction, typically used using precast combined steel plate operating room, wall For high load-bearing square steel tube frame structure as keel, plasterboard is pasted at dalle back, and dalle face sprays antibiotic paint, and Constructed in engineering site, and be related to a variety of specialty welding, cutting, cut the process such as stickup and spraying, each specialty Construction needs corresponding professional, and operational procedure is more, complex process, long in time limit, costly, and operation energy consumption height etc., these are Clean operating room common problem in construction and operation.In addition site operation welding capacity is huge, light and cigarette during welding Exist to human body and injure, pyrotechnics caused by welding has detrimental effect and various potential safety hazards to environment.Dalle back Paste plasterboard and want substantial amounts of glue, its volatilization pollutes to environment.After being sprayed at the scene to dalle face, coating The volatilization of middle organic matter adversely affects to environment, the surface layer of spraying produced after using several years stain, cracking, peeling, Go mouldy, change colour etc. this it is a series of the problem of annoying the construction and development of clean operating room in hospital.Although some present hospitals exist New clean operating room uses fabricated building technology in building, but certain deficiency be present, such as to cleaning Although operating room overall structure face can quickly be assembled, carried out quickly to clean operating room overall structure face Dismounting either influences other structural planes after some structural plane is displaced, there is in this case dismounting difficulty it is big, The problems such as structural material after dismounting can not repeat to recycle.Construction technique that can not be to clean operating room is really accomplished soon completely The requirement such as fast Assembly And Disassembly and environmental protection and energy saving.

Ceiling joist is the important composition part at the top of assembling clean operating room, to the top of assembling clean operating room Stability Analysis of Structures plays very important effect.During assembling clean operating room is developed, a kind of structure is developed in the lump Unique ceiling joist.

The content of the invention

For the utility model in view of the above-mentioned problems, providing a kind of ceiling joist, the ceiling joist can effectively ensure that assembled is clean The Stability Analysis of Structures of net operating room is firm.

According to the technical solution of the utility model：A kind of ceiling joist, it is characterised in that：Including top arranged in parallel Plate, bottom plate, left plate, right plate are set, the top plate, bottom plate, left plate, right plate, which are formed, to be cut between the top plate and bottom plate Face is the through hole of rectangle；Top plate top surface sets the first snap arm, both the second snap arm, the first snap arm, the second snap arm top opposite curved Neck is formed after folding；Right side plate top surface is upwardly extended to form baffle plate, and the relative surface of both the baffle plate, second snap arm, which tilts, to be set There is fin plate, and the fin plate in baffle plate, the second snap arm is arranged in pairs, bottom plate bottom surface is laid with the circle extended along its length Arc is raised.

As further improvement of the utility model, cell body is formed between two neighboring fin plate, cell body is towards top plate table Face is obliquely installed.

As further improvement of the utility model, the bottom plate corresponds to right plate side and sets loading plate, loading plate It is arranged in a mutually vertical manner with right plate.

As further improvement of the utility model, both first snap arm, second snap arm bending part are equipped with circle Arc chamfering.

As further improvement of the utility model, top plate is extended on the outside of left plate.

It is of the present utility model to have technical effect that：The utility model product structure is stable, firm, has neck and fin plate Groove, during assembled clean operating room, realized by neck and fin board slot and be connected with corresponding part, on ceiling joist Circular arc projection can increase space contact surface between lower shrouding and ceiling joist, by played after stickup increase frictional force with And the effect of firm pasting degree.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is that ceiling joist of the present utility model assembles block schematic illustration.

Embodiment

Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.

In Fig. 1, including top plate 1, bottom plate 2, left plate 3, right plate 4, loading plate 5, circular arc projection 6, the first snap arm 7, Two snap arm 8, baffle plate 9, neck 10, fin plate 11, through hole 12, injection right-angle connector 13 etc..

As shown in figure 1, the utility model is a kind of ceiling joist, including top plate 1 arranged in parallel, bottom plate 2, it is described Left plate 3, right plate 4 are set between top plate 1 and bottom plate 2, and the top plate 1, bottom plate 2, left plate 3, the Formation cross-section of right plate 4 are The through hole 12 of rectangle；The top surface of top plate 1 sets the first snap arm 7, the second snap arm 8, and the first snap arm 7, both tops of the second snap arm 8 are opposite Neck 10 is formed after bending；The top surface of right plate 4 upwardly extends to form baffle plate 9, the relative tables of both the baffle plate 9, second snap arm 8 Face is provided tiltedly with fin plate 11, and the fin plate 11 in baffle plate 9, the second snap arm 8 is arranged in pairs, and the bottom surface of bottom plate 2 is laid with edge The circular arc projection 6 of length direction extension.

Cell body is formed between two neighboring fin plate 11, cell body is obliquely installed towards the surface of top plate 1.

Bottom plate 2 corresponds to the side of right plate 4 and sets loading plate 5, and loading plate 5 is arranged in a mutually vertical manner with right plate 4.

Both first snap arm 7, the second snap arm 8 bending parts are equipped with circular arc chamfering, and top plate 1 extends to the outside of left plate 3.

The utility model product uses extrusion forming of aluminum alloy materials, the keel frame knot as furred ceiling shrouding surrounding Structure uses, and the first half is provided with neck 10, by being fixed on after being connected with furred ceiling hanging piece on construction ceiling, set on the side of neck 10 U-shaped teeth groove is put, U-shaped teeth groove is formed by the fin plate 11 in the snap arm 8 of baffle plate 9 and second.During assembled clean operating room, on By being stuck in after bending inside U-shaped teeth groove, U-shaped teeth groove uses barb structure, is easy to the firmness of upper sealing plate clamping shrouding. U-shaped card slot has rectangular through hole 12 below, and furred ceiling shrouding surrounding keel frame is formed after being connected with injection right-angle connector 13.

The left side edge of neck 10 is slightly shorter than at the left side edge of rectangular through holes 12, it is intended that after lower shrouding bending After laying rectangular through hole 12 below, the bending edges edge of lower shrouding and the left side of neck 10 are formed as integral planar.Rectangular The following of shape through hole 12 uses waveform base, and there are extension step, i.e. loading plate 5 in the right side of rectangular through holes 12, and this is at two Purpose is to increase gluing jail after overlaying on the bottom of furred ceiling shrouding surrounding keel frame by gluing mode after lower shrouding bending Tenacity.In addition it is filled between upper sealing plate and lower shrouding using insulation material, filled thermal insulation materials thing is laid on rectangular On the loading plate 5 on the right side of shape through hole 12.Pass through gluing side in the top and bottom of filled thermal insulation materials thing and upper sealing plate, lower shrouding Formula forms whole ceiling board, ensures the structural strength of whole clean operating room furred ceiling.
