Main keel

Technical Field

The utility model relates to a main joist. The suspended ceiling is suitable for the suspended ceiling field in interior decoration.

Background

The suspended ceiling decoration is the essential part of interior decoration, and good reasonable suspended ceiling design can compensate the original not enough of building structure, still has functions such as cutting apart space, reinforcing interior decoration effect. The light trough is an important component of the ceiling structure and is generally located on the periphery of the ceiling structure and close to the wall side. At present, the lamp trough prefabricated part is mostly hung and installed on the top plate by adopting a suspender and other structures, the installation is slightly complicated, the ceiling design is limited by the existence of the suspender, and the suspender needs to be hidden by a method.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: aiming at the problems, the main keel with simple structure, convenient manufacture and lower cost is provided to install the light trough prefabricated member conveniently and quickly.

The utility model adopts the technical proposal that: a main joist, its characterized in that: the main keel leveling device is provided with a bottom plate, side plates which are parallel to each other and vertical to the bottom plate are respectively arranged on two sides of the front surface of the bottom plate, hooks are arranged at the ends of the side plates far away from the bottom plate, a containing groove which is arranged along the axial direction of the main keel is arranged in the middle of the bottom surface of the bottom plate, and leveling contact surfaces are arranged on the bottom surface of the bottom plate and two sides of the containing;

the groove bottom plate of the containing groove is provided with a row of mounting holes I which are arranged along the axis of the main keel, and the leveling contact surface is provided with a row of mounting holes II which are arranged in parallel to the axis of the main keel.

Kraft paper is pasted on the outer side surface of the main keel.

An annular magnetic sheet is arranged corresponding to the mounting hole I and located between the kraft paper and the bottom plate.

The utility model has the advantages that: the utility model discloses well main joist accessible wears to adorn expansion bolts in mounting hole I and is fixed in the wall, and expansion bolts can be hidden to the storage tank on the bottom plate to make the leveling contact surface of storage tank both sides closely laminate with the wall, stable in structure, it is firm reliable. The utility model discloses the accessible is worn to adorn on the screw of mounting hole II is fixed in the wall with the main joist, and makes leveling contact surface and wall closely laminate, stable in structure, and is firm reliable. The utility model discloses the nut that the annular magnetic sheet adsorbability of I position of well mounting hole was used for pressing from both sides tight this main joist prevents that lock nut is not hard up.

Detailed Description

As shown in fig. 1 and 2, the present embodiment is a main keel, which has a bottom plate and side plates located at two sides of the bottom plate, wherein the middle of the bottom plate protrudes upward and forms a receiving groove on the bottom surface thereof, the receiving groove is disposed along the axial direction of the main keel, two sides of the receiving groove on the bottom plate are leveling contact surfaces, and the leveling contact surfaces at two sides are located on the same plane; in this example, the lower end of the side plate is connected with the leveling contact surface at the same side and is vertical to the same, and the upper end of the side plate is provided with a hook.

In the embodiment, a groove bottom plate of the accommodating groove is provided with a row of mounting holes I which are arranged along the axis of the main keel; and a row of mounting holes II which are arranged in parallel to the axis of the main keel are formed in the leveling contact surface.

In this embodiment, 50g of yellow kraft paper is applied to the outer surface of the main keel through a hot melt adhesive. An annular magnetic sheet is arranged corresponding to the mounting hole I and located between the kraft paper and the bottom plate.

Use light trough mounting structure of main joist in this embodiment includes the main joist, expansion bolts and fastener, as shown in fig. 3, correspond mounting hole I on the main joist and install the expansion pipe on wall or top surface, expansion bolts is fixed in wall or top surface under the effect of shank of bolt, the expansion pipe, lock nut I, the suit adjusting nut on the shank of bolt, the wall or top surface are hugged closely to the main joist bottom surface, the shank of bolt passes mounting hole I on the main joist and presss from both sides tight main joist through lock nut II, lock nut I and adjusting nut arrange in the storage tank of the bottom surface of main joist. In the embodiment, the annular magnetic sheet of the mounting hole I adsorbs the adjusting nut and the locking nut II on two sides of the main keel, so that the adjusting nut and the locking nut II clamping the main keel are prevented from loosening as far as possible. The clamping piece is matched with the hooks on the two sides of the main keel to realize installation, and structures such as a lamp groove are installed on the clamping piece.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
