Description

Concrete floor dividing joint structure

This creation is about a concrete floor dividing joint structure, especially an innovative structural designer of a floor dividing joint structure using concrete located in a dividing joint defined between the basic materials of two buildings.

Generally, the top floor of a large building has a relatively large area, and the floor is often covered with thermal insulation bricks due to thermal expansion and contraction, and concrete insulation is directly used without thermal insulation bricks. However, the heat-insulating bricks or concrete will swell and squeeze due to long-term exposure to high temperature and sunlight, which can easily cause the heat-insulating bricks or concrete to bulge. Therefore, in order to improve this phenomenon, special tools will be used on the floor of the floor during construction. Cut out several split joints, and pour a special joint sealant into the split joints, but the joint sealant construction is troublesome and time-consuming, which makes the construction cost high, and it is easy to seep out during pouring and cause dirty brick surface. It is easy to cut the waterproof layer or other parts when using a knife to cut the dividing seam, which may cause troubles for the industry.

In view of the above phenomenon, the creator of this case is based on years of production experience, and then creates a wider range of practical creators.

That is, the main purpose of this creation is to provide a concrete floor dividing joint structure; the problem to be solved is to cut several dividing joints on the floor of the floor with a special tool during conventional construction. , And pour a special joint sealant into the split joints, but the joint sealant construction is troublesome and time-consuming, which makes the construction cost high, and it is easy to seep out and cause the brick surface to be dirty when pouring. It is easy to cut the waterproof layer or other parts from time to time, which can easily cause problems for the industry to improve and break through;

The technical feature to solve the problem mainly includes a base, the base includes a bottom and sidewalls separately arranged on both sides of the bottom, a positioning space is formed between the two sidewalls, and a side portion is extended laterally on both sides of the base ; An elastic body made of polycarbonate (Polycarbonate, PC for short), the elastic system is positioned in the positioning space of the base, and clamped and fixed between the two side walls of the base; a protective cover, a cover Located at the top end of the elastic body, the protective cover includes a top plate and two opposite side plates extending from both sides of the top plate. The top plate and the two side plates jointly define a cover space. The top end of the elastic body is located at the cover. Inside the space, and the two side plates are clamped on the opposite side edges of the elastic body;

With this innovative and unique design, the elastic body made of polycarbonate in this creation has good heat resistance and cold resistance that can be possessed during concrete grouting, and can maintain a high temperature in the temperature range of -135℃～120℃ The mechanical strength, so it can effectively follow the thermal stress and deformation of concrete, and the top end of the elastic body is covered with a protective cover to protect the elastic body from abrasion or damage, and the protective cover has a plurality of pressing ratchets to improve and The relative clamping force of the elastic body is tight, so there is no need to worry about the problem of the protective cover and the elastic body falling off.

Please refer to Figures 1~6, which are the preferred embodiments of the concrete floor split joint structure of this creation. However, these embodiments are for illustrative purposes only and are not restricted by this structure in the patent application; The creation is applied to the dividing seams defined by the large-area floor slab of the building. The dividing seam structure A includes:

A base 10, the base 10 includes a bottom 15 and sidewalls 12 separately provided on both sides of the bottom 15, a positioning space 13 is formed between the two sidewalls 12, and one side 11 extends laterally on both sides of the base 10; A plurality of particles 14 are formed on the surface of the bottom 15 and the side wall 12 of the base 10 opposite to the positioning space 13, and the surfaces of the two sides 11 of the base 10 are also formed with a plurality of particles 14, by the two of the base 10 The plurality of particles 14 on the surface of the side portion 11 can increase the relative frictional resistance with the concrete C, and the bottom 15, side portion 11, and the side wall 12 of the base 10 are hollowed out to form an elastic space 16 respectively. The space 16 can increase the relative elastic compression margin of the concrete C relative to the base 10;

An elastic body 20 made of polycarbonate (PC for short). With the good heat resistance and cold resistance of the polycarbonate material itself, it can maintain a relatively high temperature in the temperature range of -135℃～120℃. High mechanical strength. In addition, the elastic body 20 is positioned in the positioning space 13 of the base 10 and clamped and fixed between the two side walls 12 of the base 10 by the bottom 15 and the side walls 12 of the base 10 A plurality of particles 14 are formed on the surface of the positioning space 13 to increase the relative friction resistance between the elastic body 20 and the base 10;

A protective cover 30 is arranged on the top end of the elastic body 20. The protective cover 30 includes a top plate 31 and two opposite side plates 32 extending from both sides of the top plate 31. The top plate 31 and the two side plates 32 jointly define a A cover space 33. The top end of the elastic body 20 is located in the cover space 33. The cover space 33 is further provided with a top catch 331 at a relative position relative to the top plate 31. The top catch 331 abuts the elastic The top surface of the main body 20, and the two side plates 32 are clamped on the opposite side edges of the elastic main body 20, wherein the two side plates 32 of the protective cover 30 and the cover space 33 are formed with a plurality of pressing ratchets on the opposite surface positions 34. The forcing ratchet tooth 34 includes a transverse tooth surface 35 and a guide inclined surface 36 extending obliquely downward from one end of the transverse tooth surface 35, so that the top end of the elastic body 20 is pressed against the ratchet tooth 34 by the plurality of It can preferably be pressed against the inside of the cover space 33, and the pressing ratchet 34 can be assembled into the elastic body by the relative co-configuration of the guide slope 36 and the transverse tooth surface 35 It is only necessary to push the button downwards at 20 o'clock to make the plurality of pressing ratchet teeth 34 be pressed against the relative positions of the two sides of the elastic body 20 relative to the engagement.

Based on the above description, please refer to Figs. 1 to 6 again. The split joint structure A of this creation is arranged and staggered on the large-area floor slab of the building in a large number of arrangements and is not grouted. On the split joint defined by the waterproof layer B, the constructor can first point the concrete C on the bottom end of the elastic body 20 and attach it to the waterproof layer B to locate the split joint structure A, and then the concrete C It is poured on the waterproof layer B. After curing, the split joint structure A is the split joint between the basic materials of the building, and the top plate 31 of the protective cover 30 can be exposed on the floor surface of the concrete C. On the other hand, the elastic body 20 is made of polycarbonate, so it has good heat and cold resistance when concrete C is grouted. It can maintain high mechanical strength in the temperature range of -135℃～120℃, so it can Effectively follow the concrete C cold and heat stress, thermal expansion and contraction deformation.
