Abstract

The invention discloses a main support structure for a ceiling. The main support structure comprises main keels made of plastics, a connector made of plastics is fastened to the lower end of each main keel, and the lower end of each connector is sleeved with a metal insert. A panel fastener with a downward opening is connected above each main keel, and clamping arms matched with the side wall of each main keel are arranged on two sides of each panel fastener. By sleeving the metal inserts to the plastic connectors and fastening the connectors to the main keels made of plastics, decorating effect of the inserts is guaranteed while the inserts are convenient to mount. Besides, both the main keels and the connectors are extrusion molded parts, are convenient to fasten and low in cost, so that total cost of the ceiling is reduced.

Description

A kind of main support structure of furred ceiling

Technical field

The invention belongs to the interior decoration building materials field, be specifically related to a kind of main support structure of interior decoration furred ceiling.

Background technology

The mounting structure of present existing decorative panel all is the tiling structure, is close to installation between each decoration panel, does not decorate gridiron between the adjacent panels.The interior decoration furred ceiling outward appearance of this structure is single, poor visual effect, therefore the applicant proposes a kind of hang ceiling panel mounting structure (CN201460113) in patent application before, on the basis of existing panel tiling mounting structure, between panel, increase and decorate gridiron, decorating gridiron has the keel of fixed ceilings to constitute, thereby improves decorative effect.Yet gridiron part and keel integral body all are plastic materials, and decorative effect is not good.And if gridiron integral body is all used shape, though decorative effect is good, whole materials are many, and price is higher, cause the whole cost of finishing higher.

Summary of the invention

The objective of the invention is: at the deficiency that prior art exists, provide a kind of furred ceiling main support structure of novel structure, guarantee that furred ceiling has decorative effect and mechanical strength and lower cost preferably.

For realizing the present invention's purpose, be achieved by the following technical solutions: a kind of main support structure of furred ceiling, include the main joist of plastic material, the main joist lower end is connected with the connector of a plastic material, and the connector lower end is socketed with the panel of metal material.

Described main joist top is connected with the panel fastener that an opening arranges down, and panel fastener both sides are the clamp arms that match with the main joist sidewall.The panel of furred ceiling is clamped between main joist sidewall and the clamp arm.

Described main joist lower end is provided with downward opening clamping mouth; Described connector upper end be arranged with two Shang Kabi, on block the wall upper end and be connected with wall extension respectively, two distances that go up between the card wall increase progressively from bottom to top, the distance between two wall extensions is successively decreased from bottom to top; The inner wall shape of clamping mouth and the described outside wall surface that goes up Ka Bi, wall extension are complementary.

Described two angle r that go up card wall extended line are 20 °, and the angle s of described two wall extension extended lines is 77 °.Connector is easy to snap onto in the clamping mouth like this, and connector is connected afterwards, and Stability Analysis of Structures is difficult for loosening with the clamping mouth.

Both sides, described connector lower end are provided with outwards horizontally extending wall built-up down; Described panel end face is the rectangle of upper end open, and the upper end open place is provided with the wall that articulates that extends in opposite directions; Articulate wall hanging on described wall built-up down.

Articulate distance c between the wall apart from a less than panel two between the described connector two side, and on the connector distance b between two following wall built-ups less than in the panel between the wall of the left and right sides apart from d.By such setting, but panel move left and right in the panel installation process is unlikely to counter plate generation inhibition, and after the complete installation of panel, panel is clamped fully, can not produce movement again, and Stability Analysis of Structures is firm.

Be provided with the cavity of rectangle in the middle of the described connector.

Described panel inner bottom part is provided with a T shape limited wall, leaves the gap between T shape limited wall upper end and the connector bottom.T shape limited wall has prevented that panel from producing and has come off before not being completely fixed, and the move left and right of panel is convenient in described gap.

Described main joist is the cavity of hollow, is connected with horizontally disposed rinforcement bar between the wall of the left and right sides in the cavity.

Compared with prior art, the invention has the beneficial effects as follows: the panel of the connector socket metal material by described plastic material, again connector is snapped fit onto on the main joist of plastic material, so both guaranteed the decorative effect of panel, made things convenient for the installation of panel again, described main joist and connector are extrusion molding spare, and clamping is convenient and cost is lower, have reduced the whole cost of furred ceiling.

The specific embodiment

With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.

To shown in Figure 6, the main support structure of the described a kind of furred ceiling of present embodiment includes the main joist 2 of plastic material according to Fig. 1, and main joist 2 lower ends are connected with the connector 3 of a plastic material, and connector 3 lower ends are socketed with the panel 4 of metal material.

Described main joist 2 tops are connected with the panel fastener 1 that an opening arranges down, and panel fastener 1 both sides are the clamp arms 12 that match with main joist 2 sidewalls.Panel fastener 1 is metal material, and panel fastener 1 upper end wall is fixedlyed connected with the upper end of main joist 2, and panel fastener upper end wall and clamp arm 12 crossover positions are provided with kink 11, and its structure makes clamp arm 12 possess elasticity preferably as shown in Figure 2.The joint face of panel 5 is stuck between main joist 2 sidewalls and the clamp arm 12.

Described main joist 2 lower ends are provided with downward opening clamping mouth 22; Described connector 3 upper ends be arranged with two go up card walls 32, on block wall 32 upper ends and be connected with the distances that 33, two of wall extensions go up between the card walls 32 respectively and increase progressively from bottom to top, the distance between two wall extensions 33 is successively decreased from bottom to top; The inner wall shape of clamping mouth 22 and the described outside wall surface that goes up card wall 32, wall extension 33 are complementary.As Fig. 2, wall extension 33 is fitted with the ramp 221 of clamping mouth 22, on block wall 32 and fit with the lower inclined plane 222 of clamping mouth 22.
