Abstract

The utility model belongs to the civil engineering earth building reinforcing technical field, specifically to an existing earth building earth wall body reinforcing device through wooden columns and wooden beams. The device which comprises an earth wall body (1) is characterized in that at least two wooden columns (2) are equipped on the sides of the earth wall body (1) along the length direction and the width direction. A wooden beam (3) is connected on the top of the wooden columns (2). The wooden columns (2) and the wooden beam (3) make the earth wall body (1) encircled. The bottom of each wooden column (2) is embedded in the foundation (4) of the earth wall body. The device enables an existing structure to be reinforced and have better anti-seismic performances on the premise that no structural deadweight is increased and the original component sizes are not changed. Meanwhile, the device has the advantages of low manufacturing cost, simple technology and convenient construction.

Description

A kind of primary raw soil building soil wall pin wooden frame bracing means

Technical field

The utility model belongs to the earth building reinforcing technique field of civil engineering, is specifically related to a kind of primary raw soil building soil wall pin wooden frame bracing means.

Background technology

Along with China's rapid economy development, urban architecture is resisted the ability of earthquake disaster and is constantly strengthened, but in rural area, China Midwest because poor, still have a large amount of earth buildings to exist, this part building aseismicity ability is very low, and can't replace with modern architecture in a short time, the most direct effective way is carried out strengthening reconstruction exactly, therefore, to seem very urgent of the demand of China's rural area primary raw soil building soil wall reinforcing technique, and the research of this respect is almost blank, meanwhile, whole nation rural area local-style dwelling houses seismic safety engineering construction starts comprehensively, and the demand of visible this respect is extremely urgent and relevant.

Summary of the invention

The purpose of this utility model is: vast western rural areas is because poor, and immature soil structural construction also will extensively exist in a period of time, and the shear resistance of such house wall is lower, poor seismic behavior.For reducing the seismic damage loss of rural area active service immature soil structural building, at the characteristic of immature soil wall and the economic capability in villages and small towns practical bracing means has been proposed, to improve the anti-seismic performance of this type of active service building.

The utility model realizes that above-mentioned technical purpose adopts following technical scheme:

A kind of primary raw soil building soil wall pin wooden frame bracing means, comprise the cob wall body, it is characterized in that, side at cob wall body length direction and width, at least be provided with two pins, the top of pin is connected with wooden frame, and pin and wooden frame coat the cob wall body, and the pin bottom is imbedded among the basis of cob wall body.

As preferably, described pin is close in the groove that the cob wall body offered.

As preferably, be connected by the tenon fourth of the twelve Earthly Branches between described pin and the wooden frame.

Primary raw soil building soil wall pin wooden frame bracing means provided by the utility model has the advantages such as size that do not increase dead load and do not change original member substantially, and cheap, technology is simple, construction is convenient.Discover by experiment simultaneously that reinforcing limit shear-carrying capacity, the extreme displacement of back wall under action of horizontal seismic has increased significantly.

Description of drawings

Fig. 1 is provided with the primary raw soil building soil wall pin wooden frame bracing means structure chart of pin for cob wall body two ends;

Fig. 2 is respectively equipped with the primary raw soil building soil wall pin wooden frame bracing means structure chart of pin for cob wall body length direction side and cob wall body two ends;

Fig. 3 is provided with the primary raw soil building soil wall pin wooden frame bracing means decomposition chart of pin for cob wall body two ends.

Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment

A kind of primary raw soil building soil wall pin wooden frame bracing means provided by the utility model as shown in Figure 1 and Figure 2, comprise cob wall body 1, it is characterized in that, side at cob wall body 1 length direction and width, at least be provided with two pins 2, the top of pin 2 is connected with wooden frame 3, and pin 2 and wooden frame 3 coat cob wall body 1, and pin 2 bottoms are imbedded among the basis 4 of cob wall body.

As shown in Figure 3, pin described in the said apparatus 2 is close in the groove 5 that cob wall body 1 offered.Riveted joint or the tenon fourth of the twelve Earthly Branches are connected mutually between pin 2 wherein and the wooden frame 3.

As preferably, as shown in Figure 3, a kind of primary raw soil building soil wall pin wooden frame bracing means provided by the utility model can adopt following technology: (former molded dimension 3300 * 2400 * 480mm is an example with body of wall) in work progress

(1) dig up/down perforation groove 5 at existing immature soil wall outer side two ends, groove top passes to the top of a wall, and the bottom is to below 4 surfaces, body of wall basis (degree of depth is greater than 100mm), the about 100mm * 100mm of groove sectional dimension;

(2) select the about 100 * 100mm lumps of wood of sectional dimension post to embed in the body of wall groove 5, be close to groove walls, the pin root embeds in the body of wall basis, and column cap exceeds wall part and makees tenon (tenon length equals wooden frame thickness, about 60mm);

(3) with supporting bracket housing frame or purlin fulcrums such as jack, add wooden frame, the wooden frame width can be wide greater than wall (decide according to the pin tenon, wide go out part in order to go into pin in the fourth of the twelve Earthly Branches);

(4) the wooden frame termination is made mortise and is connected with the pin tenon tenon fourth of the twelve Earthly Branches;

(5) the pin wooden frame is connected with dog with original timber roof truss in house etc.

The pin that in the practice of construction process, can select suitable radical according to the thickness and the stressing conditions of body of wall.
