Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

The first embodiment is as follows:

a roofing fair-faced concrete ditch, comprising: a drainage channel 1 and a leakage-proof structure 2. Specifically, the contents are shown in fig. 2 and fig. 3. The drainage channel 1 includes a side wall 11 and a flow guide portion 12. The sidewalls 11 are respectively disposed at both sides of the guide part 12. The side wall 11 is attached to the flow guide portion 12. Meanwhile, the upper surface of the side wall 11 is inclined to collect rainwater to the diversion part 12. The leakage-proof structure 2 is connected with the side wall 11 and protrudes from the surface of the side wall 11. Specifically, the leakage preventing structure 2 includes an extension face 21, a dripping portion 22 for dripping the water body. Wherein the extension surface 21 extends from the top end of the side wall 11 toward the flow guide portion 12 so as to be located above the flow guide portion 12. The dripping part 22 includes a flow guiding surface 221 extending from the extension surface 21 toward the lower flow guiding part 12, and a flow stopping surface 222 extending from a distal end of the flow guiding surface 221 toward the side wall 11, such that an included angle is formed between the flow guiding surface 221 and the flow stopping surface 222. The included angle between the flow guide surface 221 and the flow stop surface 222 is less than or equal to 90 deg.

When rain falls onto the roof, the rain will flow under the influence of gravity along the inclined upper surface of the side wall 11 in a direction towards the flow guide 12. As the rainwater gradually flows, the rainwater flows through the upper surface of the side wall 11, onto the extension surface 21, and continues to flow under the drainage action of the extension surface 21 until flowing to the drop portion 22. At this time, the rainwater will continue to flow along the drainage surface 221 under the action of gravity and the tension of water, and when the rainwater flows to the connection between the drainage surface 221 and the flow stopping surface 222, the rainwater cannot continue to flow along the flow stopping surface 222 under the action of the tension of water because the included angle between the drainage surface 221 and the flow stopping surface 222 is less than or equal to 90 °. At this time, rainwater drops at the connection between the drainage surface 221 and the flow stopping surface 222. Since the dropping part 22 protrudes from the surface of the sidewall 11 of the drainage channel 1, the rainwater will directly drop on the diversion part 12, rather than drop on the gap between the diversion part 12 and the sidewall 11. From this, effectually avoided the long-term direct impact gap of rainwater, caused gap department infiltration.

Preferably, the angle between the flow guide surface 221 and the flow stop surface 222 is less than 90 °.

Example two:

a construction tool comprises a body 3. The body 3 is used to construct the drip part 22 as described in the first embodiment. Specifically, as shown in fig. 2, the main body 3 includes a drainage structure 32 and a flow stop structure 33. The flow stop structure 33 is a substantially rectangular member, and an inclined surface 331 is provided at one end of the flow stop structure 33, and the inclined surface 331 is inclined from one end of the flow stop structure 33 to the other end thereof to form the flow stop surface 222. The drainage structure 32 is a rectangular member, and a structure surface 321 for constructing the drainage surface 221 is provided on one side of the drainage structure 32. The drainage structure 32 is detachably connected to the flow stop structure 33. When the drainage construction part 32 and the flow stop construction part 33 are attached together, the construction surface 321 is attached to the flow stop construction part 33, so that the construction surface 321 meets the inclined slope 331. Wherein, the included angle between the inclined plane 331 and the construction surface 321 is less than or equal to 90 degrees.

Meanwhile, a support portion 5 is also included. The support 5 may be a tubular structure or a plate-like structure. The end of the support portion 5 can be attached to the side of the drainage construction portion 32 away from the flow stop construction portion 33. The support part 5 is detachably connected to the drainage structure part 4.

The support pad 4 is detachably provided at an end of the flow stop structure 33 away from the inclined surface 331.

In particular, reference is made to the description of figure 1. In the conventional drainage ditch construction method, mortar or fine stone concrete different from concrete is used for constructing the side wall 11 of the drainage channel 1. This results in a joint between two different materials that is susceptible to cracking or partial structural failure due to thermal barrier contraction. Meanwhile, the mortar or the fine stone concrete is manually painted at the position where the mortar or the fine stone concrete is adopted, the adhesion between the mortar or the fine stone concrete and other materials is poor, and the mortar or the fine stone concrete is easy to separate from other materials even if the mortar or the fine stone concrete is not affected by heat barrier and cold contraction. On the other hand, refer to the contents shown in fig. 2. The drip part 22 protrudes from the side wall 11 of the drain channel 1, and there is no support structure directly below the drip part 22 to support the drip part 22. This results in the drop portion 22 being easily deformed and collapsed when constructed.

Thus, the contents shown in fig. 4 are referred to when the present construction tool is actually used. The positions of the two side walls 11 of the drainage channel 1 are set. The two support pads 4 are respectively corresponding to the construction positions of the two side walls 11 of the drainage channel 1, and the support pads 4 are positioned at the joint between the construction positions and the flow guide part 12 of the drainage channel 1. The flow stop structure 33 is placed on the support pad 4 so that the end of the flow stop structure 33 not provided with the inclined surface is attached to the support pad 4. The drainage structure part 32 is placed at the installation position on the flow stop structure part 33, and the drainage structure part and the flow stop structure part are fixed by screws. At this time, one side of the flow stop structure part 33 corresponds to the position where the side wall 11 of the drain passage 1 is constructed, and the other side of the flow stop structure part 33 is bonded to the drainage structure part 32. The two flow stop structures 33 are mirror images of the center line of the drain passage 1. The support portion 5 is placed between the two drainage construction portions 32 so that both ends of the support portion 5 are respectively attached to the side surfaces of the two drainage construction portions 32, thereby supporting the flow stop construction portion 33 through the drainage construction portions 32. The flow stop structure 33 is prevented from falling down during use. After the construction tool is built, concrete is poured, and as the height of the concrete increases, the concrete flows over the inclined surface 331 of the flow stop construction section 33 and enters the groove formed by the engagement of the inclined surface 331 and the construction surface 321, thereby constructing the flow stop surface 222. And continuously pouring concrete, so that the concrete fills the grooves, and along with the continuous pouring of the concrete, the concrete continuously spreads upwards along with the construction surface 321 attached to the drainage construction part 32. Thus, the construction surface 321 is constructed, and the dropping portion 22 having a solid structure is constructed. At this time, the concrete is continuously poured until the height of the concrete reaches the designated height. The construction of the extension surface 21 and the upper surface of the sidewall 11 can be accomplished by using existing tools, which are not described herein. After the concrete is solidified and shaped, the construction tool can be dismantled.

In summary, the construction tool can effectively construct the fair-faced concrete ditch for roof as described in the first embodiment, and on the other hand, in the construction process, the side wall 11 of the drainage channel 1 is integrally formed with the peripheral structure by using concrete without using mortar or fine stone concrete, so that the problems of cracking and falling off at the joint between two different materials caused by different materials are effectively avoided. Meanwhile, manual painting is not needed during construction, so that manpower is effectively saved.

The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the utility model as defined in the appended claims.
