Description

Tool for mounting and fixing ceiling suspender

Technical Field

The utility model relates to an appurtenance of ceiling construction usefulness, specifically speaking are tools that are used for ceiling jib installation fixed.

Background

In the building engineering, especially the equipment installation and decoration engineering, for example, the engineering of installing blower pipe equipment, ceiling decorative plate and the like, and arranging hanger rods under floor plates, the hanger rods are required to be installed after drilling holes on concrete floor plates of a ceiling (ceiling). The expansion bolt is welded at the top of the suspender, and the nut at the bottom of the bolt is screwed after the expansion bolt is inserted into the drilled hole to complete installation. Then the equipment facilities are lifted by the lower lifting hook of the hanger rod, so that the equipment facilities are hidden in the suspended ceiling layer, and the effects of reducing occupied area and being attractive are achieved. Since the structural floor slab of the ceiling is constructed first, the worker needs to raise his head to install the boom above the structural floor slab, and needs to operate on the movable ascending frame (mobile scaffold) erected, the floor is high, the ascending frame also needs to be erected at a high height, and the ascending frame needs to be reinforced, the worker is cared, or a mechanical ascending vehicle is used in order to increase the safety, so that the construction is a small investment. And the lower part of the object equipment born by the hanging bar can be a passage for personnel to pass through, and particularly in public places, the hanging bar is dense in personnel and has high requirements on the firmness and the reliability of the installation of the hanging bar.

The material specification diameters and the like of the hanger rod and the expansion bolt can be calculated through stress, but the hanger rod and the expansion bolt are basically not damaged in the conventional falling accident of hanger rod equipment, the problems of hanger rod fracture, unqualified bolt slippage and the like rarely occur, and most of the accidents of hanger rod falling and equipment falling are caused because the expansion bolt is not fully screwed into a structural floor slab, a nut is not screwed in place, an expansion pipe is not fully propped, and the whole expansion bolt is completely pulled out of a concrete floor slab.

The known ceiling hanger bar mounting and securing means therefore suffer from the various inconveniences and problems described above.

Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

Example 1

The utility model discloses an instrument for ceiling jib installation is fixed, including handheld pole, metal round cap.

Referring to fig. 1, fig. 1 is a schematic view of a tool structure according to an embodiment of the present invention. As shown in the figure, the handheld rod is a threaded steel bar rod 1, and the diameter of the steel bar is 18 mm.

Fig. 2 is a schematic structural view of a metal round cap according to an embodiment of the present invention, and fig. 3 is a top view of fig. 2. The metal round cap is a double-horn-shaped round cap 2, an axial open slot 3 is formed in the circumferential side face of the metal round cap, the size of a slot at the upper part of the horn-shaped round cap is wide, the middle part of the double-horn-shaped round cap is narrow, and the lower part of the double-horn-shaped round cap is wide; the top end of the metal round cap is designed to be an inner hexagon 4, and the size specification of the inner hexagon of the metal round cap is determined according to the size of a nut of an expansion bolt which is actually used.

Wherein: the metal round cap is fixedly welded at the top end of the threaded steel bar, and the open slot is positioned at the welding opposite surface of the metal round cap and the handheld rod. The double-horn-shaped middle notch is larger than the diameter of the suspender by 2 mm. The height of the metal round cap is 6 cm.

Example 2

The utility model discloses a manufacturing method for fixed instrument of ceiling jib installation:

step 1: a long thread steel bar (or a threaded hollow steel pipe) is used as a hand-held rod, and the diameter of the long thread steel bar is 12 mm. The diameter is too thin, the rigidity is too small, the deflection deformation is large, if the diameter is too thick, the diameter is too heavy, the operation is inconvenient, and the operation of workers is easy to be tired. The length of the hand-held pole is obtained by deducting the operating height of a person according to the floor height of the installation of the suspender.

Step 2: an open type metal round cap is welded on the side face of the top of the steel bar, the round cap is similar to a wide-mouth bottle in shape, namely, the upper part of the round cap is a large round horn mouth shape, the middle part of the round cap is closed to form a thin bottle neck, and the bottom of the round cap is gradually enlarged.

And step 3: the opposite surface of the welding part of the metal round cap and the handheld rod is provided with a notch, the upper part of the notch is larger in size, the middle part of the notch is smaller (the width is slightly larger than the diameter of the hanging rod by 1-2 mm), and the bottom of the notch is gradually enlarged. The height of the metal round cap is about 4 cm.

And 4, step 4: the upper part of the metal round cap is in a regular internal hexagon (which is convenient for clamping the screw cap) close to the thin bottle neck.

Example 3

The utility model discloses a use method for fixed instrument of ceiling jib installation:

fig. 4 is a schematic view of a ceiling suspender structure according to an embodiment of the present invention, and fig. 5 is a schematic view of a tool using state according to an embodiment of the present invention. When in use, the suspender provided with the expansion bolt is buckled from the opening of the metal round cap, so that the handheld reinforcing steel bar rod 1 and the suspender 8 are integrated. Because the bottom and the upper part of the opening of the metal round cap are wider, the suspender can be clamped in from the upper part and also can be clamped in from the lower part, and the suspender can be effectively clamped because the size of the middle bottleneck is smaller, and the suspender can not be easily separated from the handheld rod. After the hanger rod and the handheld rod are assembled, the handheld rod is held, the expansion bolt is aligned to a hole drilled in the floor slab in advance, and then the handheld rod is pushed upwards to ensure that the expansion bolt completely enters the concrete of the floor slab. Then, as the nut on the expansion bolt is clamped into the inner hexagon 4 in the metal round cap at the upper part of the hand-held rod, the hand-held rod can be screwed easily to drive the nut 7, and the expansion bolt pipe sleeve 6 is completely expanded, so that the expansion bolt pipe sleeve and the expansion head of the expansion bolt are tightly combined and tightly fixed in the floor slab concrete. The problems that the nut is not screwed down, the expansion sleeve is not completely expanded and the expansion bolt fails due to the fact that the nut is buckled in a sliding mode are solved.

And after the screwing operation is finished, the hand-held rod is moved downwards to enable the screw cap to move out of the metal round cap, then the suspender is held by one hand, the hand-held rod is held by the other hand to release the suspender from the opening of the metal round cap, and the suspender is installed.

The utility model has the advantages of substantive characteristics and apparent technological progress, the utility model discloses an instrument simple structure, preparation convenience, popularization nature are strong for ceiling jib installation is fixed, has reduced the use of ascending a height support body equipment, and the nut is screwed up the effect better.

The above embodiments are provided only for the purpose of illustration, and not for the purpose of limitation, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention, which is defined by the claims.
