Embodiment 1

[0030] In order to overcome the deficiencies of traditional structural fire prevention methods, the embodiment of the present invention provides a composite enclosure fireproofing reinforcement that uses wooden materials to wrap the original structure under the premise of no damage to achieve structural fireproofing and reinforcement of the original structure. method.

[0031] The method for applying wooden materials to enclosure fire protection of ancient wooden buildings proposed in the embodiments of the present invention includes: wrapping soft fireproof materials on the surface of the components of the building structure, and installing wooden materials on the surface of the soft fireproof materials; The length direction of the material adopts finger-joint connection; the splicing is adopted in the transverse direction of the wooden material; the hoop tightening parts are arranged circumferentially on the outer surface of the wood material; the hoop tightening parts are ar...

Embodiment 2

[0042] figure 1 The schematic illustration of applying the enclosure fire protection method to the building structure for the embodiment of the present invention to carry out the fire protection treatment, select the structural components at the proper position of the original structural components (including beam and column components) 5; and design the fire protection according to the size and fire protection level of the original structural components 5 The size of the material 1; design and install the wooden material 2 according to the size of the fireproof material 1 after the installation is completed; use the tongue-and-groove structure 3 with complementary geometric dimensions between the length directions of the wooden materials 2 for splicing; and along the length of the wooden material 2 Finger-joint splicing in the same direction; after the splicing of the wooden material 2 is completed, the original structural member 5 is completely wrapped; on the outer surface o...

Abstract

The invention provides a composite confining fireproof reinforcement method for building fire prevention and reinforcement by using wood materials. The composite confining fireproof reinforcement method comprises the steps that the surface of a part of a building structure is wrapped with a layer of closed soft fireproof material; a wood material is mounted outside the fireproof material in an attached mode; finger joint is adopted in the length direction of the wood material; tight splicing is carried out in the side direction of the wood material; annular tightening parts are arranged on the outer surface of the wood material; the annular tightening parts are sequentially arranged in the length direction of the wood material; and the soft fireproof material, the wood material and the annular tightening parts form a completely-closed enclosing fireproof system. The f composite confining fireproof reinforcement method can be used for fire prevention and structural reinforcement of building structures such as ancient wood buildings, concrete and steel structures; and according to the composite confining fireproof reinforcement method, no bonding exists between the building structure and an original building structure, and secondary damage to the original building structure is prevented.

Description

technical field [0001] The invention relates to the technical field of building fire prevention, in particular to a compound enclosure fire prevention and reinforcement method using wood materials for fire prevention and reinforcement of ancient wooden building structures. Background technique [0002] Building fire protection is the primary guarantee for building safety, and any building needs to adopt building fire protection technology. Especially in ancient wooden buildings, fire prevention measures are important measures that cannot be ignored. The fire protection technology research of ancient wooden buildings not only provides a reference for the fire prevention research of ancient building structures, but also reflects the protection and inheritance of cultural heritage. Ancient buildings in China are mainly constructed of flammable wooden materials. These ancient wooden buildings have a long history and cultural value. It is of great significance to protect and mai...
