Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing truss roofs for buildings and the like.

0002

[Prior Art] In order to assemble a horizontal structure such as a roof truss and its accompanying roof finishing material, a scaffolding for a work gantry is erected on the entire bottom of the truss assembly in order to prevent the roof truss from deflecting and for the assembly work. A safety facility to prevent work accidents is installed on the lower horizontal surface.

0003

[Problems to be Solved by the Invention] According to the prior art, a large amount of construction materials and assembling workers are required to assemble the work gantry, and the work at height becomes large, ensuring the safety of the workers. It is difficult to assemble the roof truss, and the construction is made up of two tiers, one for assembling the roof truss and another for assembling the ceiling, making it difficult to perform the work.In addition, a lot of specialized shoring is required for assembling the roof truss, and construction materials are not available. Transportation and removal costs are high, and the floor surface cannot be finished at the base due to the assembly of the work platform.

[0004] The present invention was proposed in view of the problems of the prior art, and its purpose is to enable roof trusses and roof finishing materials attached thereto to be constructed without scaffolding, thereby reducing the need for temporary construction materials. The object of the present invention is to provide a method of constructing a truss roof that improves workability, ensures work safety, and is highly economical.

[0005]

[Means for Solving the Problems] In order to achieve the above object, according to the truss roof construction method according to the present invention, on the working platform provided on one side of the building, the lower surface of the base plate at both ends is A horizontal roof truss on which a sliding material is layered and a guide roller is vertically installed, and a roof finishing material attached to the truss are assembled, and the surface of the foundation on both sides in the row direction supporting the roof truss is provided with a sliding material, A reinforcing plate is attached to each side, rollers at both ends of the roof truss are brought into contact with the reinforcing plate, and while rolling the rollers along the reinforcing plate, the base plate is moved along the pair of foundations. After sliding to a predetermined position, it is fixed to the base.

[0006]

[Operation] According to the present invention, a roof truss and roof finishing material attached to the truss are simultaneously assembled on a work platform provided on one side of a building, and the roof truss is prevented from sliding on the lower surface of the base plate at both ends of the roof truss. The roof truss is moved along the foundation to a predetermined installation position using the sliding material on the surface of the foundation on both sides in the row direction that supports the roof truss as a guide.

[0007] At this time, the guide rollers vertically installed on the base plates at both ends of the horizontal roof truss slide along the reinforcing plates on the side surfaces of the foundation, and the rollers are stretched against the opposing surfaces of the foundation. This prevents the roof truss from deflecting in the vertical direction. When the roof truss is moved to a predetermined position on the foundation, the truss is fixed to the foundation, and the horizontal roof truss and the finishing material attached to the truss are constructed without scaffolding.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. A truss roof assembly gantry 3 is supported by a support 1 installed on one side of the building and a framework scaffold 2 erected on the floor inside the truss roof, and the truss roof assembly gantry 3 is supported by the gantry 3 and the framework erected on the inside floor. A roof finishing material assembly gantry 5 is supported on the scaffold 4.

Then, on the truss assembly gantry 3 and the roof finishing material assembly gantry 5, the horizontal roof truss a and the roof finishing material b attached to the truss are assembled. Reference numeral 6 denotes foundation parts on both sides in the row direction that support the roof truss a, and a sliding material made of stainless steel material 7 is laid on the surface over the longitudinal direction. Furthermore, a reinforcing plate 8 made of a steel plate is integrally fixed or bonded to the upper end of the side surface of the base part 6.

A fixed ruler plate 10 is attached to the lower surface of the base plate 9 at both ends of the horizontal roof truss a, and a sliding material 11, which is a steel plate with a fluororesin sheet attached, is attached to the lower surface of the ruler plate 10. It is being In the figure, reference numeral 12 indicates a fixing bolt between the base plate 9 and the fixed ruler plate 10. A mounting plate 14 stiffened by a rib plate 13 is vertically provided on the lower surface of the base plate 9,
A roller 15 that rolls along the reinforcing plate 8 of the base portion 6 is mounted on the mounting plate 14 .

[0011] Furthermore, at a predetermined position on the base part 6,
Anchor bolt 1 for attaching roof truss base plate 9
6 is installed, but it is buried so that it does not protrude from the foundation when the roof truss slides, and a long nut 17 is attached to the upper end of the anchor bolt 16, so that the roof truss slides to a predetermined position. At this time, the base plate 9 can be fixed to the base part 6 using the mounting bolts 18 via the long nuts 17 and the anchor bolts 16.

Since the illustrated embodiment is constructed as described above, the horizontal roof truss a and the roof finishing material b attached thereto are assembled on the truss roof assembly gantry 3 and roof finishing material assembly gantry 5, and the roof truss a and the roof finishing material b attached thereto are assembled. The sliding members 11 on the lower surfaces of the base plates 9 at both ends of the roof truss a and the sliding members 7 on the surfaces of the foundations 6 on both sides in the row direction are used as guides to slide, and the rollers 15 hanging down from the base plates 9 at both ends are moved between the base plates 9 at both ends. By sliding the horizontal roof truss a along the reinforcing plates 8 on the 6 sides, the rollers 15 at both ends of the horizontal roof truss a are stretched between the opposing base parts 6 and 6, thereby preventing vertical deflection of the roof truss a. Therefore, there is no need to provide scaffolding for the work gantry on the entire lower part of the horizontal roof truss (a) for preventing the roof truss (a) from deflecting and for assembling work, as is the case in the past.

After the roof truss a has been slid to a predetermined position, the mounting bolt 18 passing through the base plate 9 is screwed into the long nut 17 at the upper end of the anchor bolt 16, and thus the horizontal roof truss a and its attachments are tightened. The roof finishing material is erected without scaffolding.

[0014]

According to the present invention, as described above, the truss roof and the accompanying roof finishing material can be constructed without scaffolding, eliminating the need for a work gantry to prevent the truss from deflecting, and making it easier to assemble the work gantry. It is easier to ensure the safety of workers by reducing the need for materials and reducing the need for work at height, and the work can be done on a small work platform that doubles as a scaffold for roof truss assembly and a scaffold for ceiling assembly. Costs for transporting and removing construction materials are reduced. Furthermore, the assembly area of the work platform is small,
Floor finishing work at the foot of the gantry becomes easier.
