Description

Light wood structure roof truss system

technical field

The utility model belongs to the technical field of civil engineering, in particular to a light wooden structure roof truss system.

Background technique

Since "flat to slope" is a renovation project that changes the flat roof to a slope roof without changing the main structure and foundation of the original building, the slope roof needs to be made of light weight materials so as not to change the load on the original roof size. Light-weight steel structure roof trusses have become a common practice in current "leveling to slope" projects due to their advantages of light weight and convenient installation and construction. And the existing light-steel structure roof is all unsatisfactory in terms of energy saving, thermal insulation, heat insulation, sound insulation and anti-seismic performance.

Utility model content

The purpose of the utility model is to provide a light-weight wooden structure roof truss system, which is suitable for the "slope conversion" project, and has low cost and strong applicability.

For achieving above object, the solution of the present utility model is:

A light-weight wooden structure roof truss system, including wooden roof trusses, support systems, wooden-based structural panels, wooden gables, wooden parapets and anti-corrosion wood, the supporting system is connected with wooden roof trusses to provide support, and wooden-based structural panels cover wooden roof trusses Above, the wooden gable is connected to the wooden roof truss and arranged at the longitudinal ends of the house, the wooden parapet is connected to the wooden roof truss and arranged at the horizontal ends of the house, and the wooden parapet and the bottom of the wooden gable are connected to the anti-corrosion wood.

The wooden roof truss is formed by connecting standard timbers through metal tooth plates, and is provided with upper chords, lower chords and webs.

The supporting system includes roof truss upper chord support, roof truss lower chord support and roof truss web support, which are respectively connected with the upper chord, lower chord and web of the wooden roof truss.

The wood-based structural board is connected with the wooden roof truss along the upper chord of the wooden roof truss.

The wooden gable is connected to the wooden roof truss through a support system or a wooden base structural board.

The wooden parapet is connected to the wooden roof truss through metal connectors.

The anticorrosive wood is connected with the original ring beam of the flat roof.

Purlins are also arranged on the wooden roof truss, and the purlins are connected with the upper chords of the wooden roof truss and the top of the wooden gable skeleton.

Due to the adoption of the above technical scheme, the utility model has the following beneficial effects: the hoisting and on-site positioning and installation of the light wood structure roof truss system of the utility model are simple and fast, no large mechanical equipment is required, wet operation of concrete can be avoided, and the construction period is short. Reduce disturbance to the residents of the community; the wooden structure building is an energy-saving green building, and its application meets my country's current requirements for building energy conservation and consumption reduction, and is in line with the country's environmental sustainable development strategy.

Detailed ways

Below in conjunction with the embodiment shown in the accompanying drawings the utility model is further described.

The light wooden structure roof truss system of the present utility model consists of light wooden roof truss 1, support system 2, wooden base structural board 3, purlin 4, wooden gable wall 5, wooden parapet wall 6, anti-corrosion wood 7, original ring beam 8 of the flat roof, It consists of metal connectors 9 and chemical bolts 10.

The light wooden roof truss 1 is usually formed by connecting standard timbers (40mm×90mm or 40mm×140mm) with smaller cross-sectional dimensions through metal tooth plates. The support system 2 mainly includes the upper chord support of the roof truss, the lower chord support of the roof truss and the web support of the roof truss. The three types of supports are generally standard timber (40mm×90mm or 40mm×140mm), and ordinary steel nails are used to connect with the upper chord and lower chord of the light wooden roof truss 1 respectively. Rods and webs are connected. The wood-based structural board 3 covers the top of the light wooden roof truss 1, and is connected with the light wooden roof truss 1 along the upper chord of the roof truss by common steel nails. The wooden gable wall 5 and the wooden parapet wall 6 are formed by connecting standard timber (40mm×90mm) with small cross-sectional dimensions with ordinary steel nails to form a skeleton, and then using ordinary steel nails to cover the wooden base structural board 3 on the skeleton to form a wall. Wooden gables 5 are arranged at both longitudinal ends of the house, and wooden parapets 6 are arranged at both ends of the house in the transverse direction. Among them, the wooden gable 5 is connected to the light wooden roof truss 1 through the support system 2, the wooden base structural board 3 and the purlin 4, and the wooden parapet 6 is connected to the light wooden roof truss 1 through the metal connector 9.

The anticorrosion wood 7 at the bottom of the wooden parapet 6 is connected with the original ring beam 8 of the flat roof through implanted chemical bolts 10, so that the entire light wooden roof truss system is firmly connected with the original structure. In the utility model, the original wooden parapet is used to replace the concrete horizontal beams that need to be newly poured, and the influence of wet construction on the original residents will be eliminated, which will bring good social benefits.

The main materials used in the combined wooden floor are: standard timber, wood-based structural panels (domestic structural panels), chemical bolts, ordinary steel nails, and special metal connectors.

The specific construction method is as follows: using the flat roof of the original house as the working surface, first implant chemical bolts on the ring beam of the original house, and the spacing can be 610 mm, and then fix the wooden parapet 6 to the original flat roof through the anticorrosive wood 7 at the bottom. On the ring beam 8, manually position and fix the pre-designed light wooden roof truss 1 and wooden gable 5 skeleton (the distance between the roof trusses can be 1220mm or 610mm). The upper chords of the roof truss and the top members of the gable skeleton are connected by common steel nails, and the support system 2 is erected at the same time. Finally, the wooden base structural board 3 is laid on the top surface of the roof truss and the outside of the wooden gable wall, finally forming a light wooden structure roof truss system.

Compared with the light steel structure roof system, the utility model has energy saving, heat preservation, heat insulation, sound insulation and shock resistance performance superior to the steel structure. The light wood structure roof truss system can provide an effective and strong wood structure system to meet various structural systems with special shapes, and eliminate the impact of construction on the original residents. It has many advantages that steel structures cannot match.

To sum up, in the "leveling to slope" project, the use of light wood structure roof truss system can produce good effects in many aspects such as economy, technology and social benefits.

The above description of the embodiments is for those of ordinary skill in the technical field to understand and apply the utility model. It will be apparent to those skilled in the art that various modifications to the device can be readily made, and the general principles described herein applied to other embodiments without inventive effort. Therefore, the utility model is not limited to the illustrative examples here, and the improvements and modifications made by those skilled in the art according to the disclosure of the utility model should be within the protection scope of the utility model.
