Description

Methods of Improving the Windproof and Earthquake Resistance of Timber Structure Buildings

technical field

The invention relates to a wooden structure house, in particular to a method for improving the windproof and earthquake resistance performance of a wooden structure house, and belongs to the construction field.

Background technique

Houses such as wooden villas are favored by people because of their high grade, comfortable living, and easy construction. Since this type of house adopts a wooden structure instead of a reinforced concrete structure as a whole, the windproof and seismic performance is one of the key issues to be considered in the construction of this type of house. A common practice at present is: use anchor bolts to connect and fix the anti-corrosion base wood with the foundation (wooden piles, concrete piles, concrete wall foundations, etc.), and then erect ground beams, wall stud columns, etc. on the anti-corrosion base wood to build a The wooden frame of the building is added to the floor and the outer wall panels to form the first layer of wooden structure; in this way, it is built layer by layer until the roof.

This approach in the prior art only pays attention to the connection between the wooden frame of the first floor and the foundation, and the connection between the foundation and the overall frame of the house and the connection between the wooden structural members is not specially reinforced, so that the wind and earthquake resistance of the house can be improved. It is not very strong, and it is not suitable to be built on the shore of the lake or on the mountain, which limits the popularization and application of wooden houses.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a method for improving the windproof and earthquake-resistant performance of wooden structures.

For realizing the purpose of the present invention, wooden structure house is strengthened from the following aspects:

① The foundation of the whole house and the foundation of the wall are casted with reinforced concrete;

②Anchor bolts are provided inside the wall foundation, and the anchor bolts extend to the roof;

③ Between the wall foundation and the first-story wooden structure wall and between the adjacent two-story wooden structure walls, flat iron bars are used for vertical reinforcement from the outside of the hoarding;

④ The corners of the frame wall are also reinforced horizontally from the outside of the hoarding with flat iron bars.

Object of the present invention can also be further realized by several schemes:

In the above-mentioned method for improving the windproof and earthquake-resistant performance of a wooden structure house, the joists at the non-load-bearing pillars of the house are connected with the main load-bearing beams by hooks.

Further, in the above method for improving the windproof and earthquake resistance performance of a wooden structure building, the joists especially refer to floor joists and ceiling joists.

Further, in the above method for improving the windproof and earthquake resistance performance of the wooden structure house, the inner corner connectors are used to fasten the double pillars at the corners.

Still further, in the above-mentioned method for improving the windproof and earthquake-resistant performance of a wooden structure house, the distance between the anchor bolts in the frame wall is 600 mm to 1000 mm.

In addition, in any one of the above-mentioned methods for improving the windproof and seismic performance of wooden houses, the connecting parts and fasteners involved are all made of iron galvanized materials.

The present invention starts from the improvement of the windproof and earthquake resistance performance of the wooden structure house, and takes measures such as strengthening the foundation, setting anchor bolts, strengthening the connection fastness between the wooden frame members and between the whole wooden structure and the foundation, and combining the construction of the building block. It is built according to the geological characteristics, which greatly improves the windproof and seismic performance of wooden houses. According to verification, the wooden structure villa constructed by adopting the technical scheme of the present invention can withstand the test of storm for a long time, and can resist earthquakes of magnitude seven and hurricanes of magnitude ten.

Detailed ways

Improving the windproof and earthquake-resistant performance of wooden structures is a systematic project. The invention grasps the technical key and proposes relatively systematic, complete and specific technical means, which have achieved good application effects. Taking the construction of wooden structure villa as an example below, the technical solution of the present invention is described in detail.

(1) Strengthen the foundation

The overall foundation of the house adopts the overall reinforced concrete structure, and a ventilated and moisture-proof wall is installed under the first floor of the house, and the foundation of the wall is also cast with reinforced concrete. As known to those skilled in the art, the casting foundation should be determined according to the geological characteristics of the building plot. A typical example is: the surrounding area is constructed with reinforced concrete with a depth of 1000-1500 mm; the interior is first backfilled and compacted, and then poured Concrete cushion (C10, 50mm thick), vibrated and smoothed, paved with waterproof foam plastic layer (20-25mm thick), bound steel bars (200mm×200mm), poured concrete (C20, 80mm thick), vibrated and smoothed, The original pulp is compacted and troweled (not less than three times).

After the foundation of the wall is completed, the basement (isolation layer) reinforced concrete reinforced wall (600mm high) is set up, and the anti-corrosion base wood is anchored on this wall.

(2) Set anchor bolts

While making the wall foundation and reinforcing the wall, set the anchor bolts. The anchor bolt can be lengthened and fastened layer by layer from bottom to top by means of screw connection, and extends to the roof, so that the wooden frame is connected from bottom to top into one body, and the structure is more firm. The setting of the number of anchor bolts: the frame wall is generally set at an interval of 1000mm, and the bolts are appropriately added at the junction of the foundation wall, and the inner wall is determined according to the load-bearing and structural conditions. Once the house is built, the anchor bolts will be hidden inside the walls.

(3) Vertical reinforcement

Between the concrete wall base and the first floor of the wooden structure wall, and between the adjacent two-layer wooden structure walls, 1mm thick flat iron bars are used for vertical reinforcement at intervals of 600mm—the flat iron bars are placed from the outside After straightening, use yellow nails to nail the wall studs, edge strips and hoardings.

(4) Horizontal reinforcement

The corners of the frame wall are also reinforced horizontally from the outside of the hoarding with 1mm thick flat iron bars to make the overall structure of the house more stable.

(5) Other measures

The joists at the non-load-bearing pillars of wooden structure villas, such as floor joists and ceiling joists, are connected to the main load-bearing beams with hooks instead of the traditional mortise and tenon connection method of wooden structures; inside corners are used between double-pillar columns at the corners The connecting parts are fastened to prevent the column from bending and deforming after being stressed, so that the load-bearing components are evenly stressed and durable.

The connectors and fasteners used in the above construction process are all galvanized to make them rust-proof and durable, and the pressure they can withstand should be greater than that of the suspended joists.
