Description

导 structure with air guiding function

This creation is about a 預鑄 structure; specifically, the creation is about a 預鑄 structure with a guiding air exclusion function.

In the construction of the building body, especially the efficiency of the column and the beam body assembly, it is one of the important steps that affect the subsequent laying and grouting operations. In addition, the quality of the column and the beam body is related to the work at the joint of the beam and column. Taking the beam body and the column body together and then grouting between the two, the space between the beam body and the column body must be filled, and the assembly work of the beam column is finally come to an end.

However, when grouting, the external air is often brought into the space between the beam body and the column body, which will cause unnecessary gas to remain in the beam-column joint during the grouting operation, which affects the structural strength. Furthermore, the material of the grouting material has a certain viscosity. If the flow rate is to be slowed down to improve the amount of residual air, it will inevitably affect the efficiency of the assembly. In other words, in order to improve the construction efficiency in accordance with the scale of the construction of the case, it is an important issue to effectively remove the air that the beam-colum joint is brought into by the grouting operation to improve the overall performance of the work.

One of the purposes of this creation is to provide a raft structure that directs air discharge at the beam and column joints.

The 預鑄 structure includes a first structure body and a second structure body, wherein the first structure body a second surface having a bottom surface facing the placement surface, a top surface facing the bottom surface, a concave portion formed on the partial bottom surface, and a plurality of grooves distributed on the bottom surface, and the space surrounded by the groove and the concave portion The cavity is connected.

As shown in the cross-sectional view of FIG. 3A, the recess 308 is recessed from the bottom surface 302 toward the top surface 304 and communicates with the venting opening 301 of the top surface 304. Further, the insertion hole 306 has a diameter larger than the diameter of the pillar 204 and has a gap 306A. In other words, during the grouting operation, the concrete flows through the recess 308 to the exhaust hole 301 from the beam-column joint, and also flows to the top surface 304 through the gap 306A in the insertion hole 306. As shown in FIG. 3A, when the second structural body 300 is hung on the first structural body 200, the bottom surface 302 is supported by the spacer 400, and then the template 500 is placed at the beam-column joint (please refer to FIG. 4).

As shown in the cross-sectional view of FIG. 3B, the ribs 204 pass through the insertion holes 306 and are joined to the ribs 204 on the first structure 200 by the splicing 206. Next, a grouting operation is prepared in which the grouting is grouted from one end of the formwork 500 and discharged at the other end. Please refer to the enlarged view of the template, the height of the grouting direction 501A is preferably lower than the height of the slurry direction 503A. Referring to the horizontal sectional view at the beam-column joint of FIG. 4, as shown in FIG. 4, the template 500 is placed on the placement surface 202 of the first structural body 200 and surrounds the periphery of the beam-column joint. Preferably, the template 500 is provided with a grouting port 501 and three grouting ports 503 at four corners, but the number of the pulping port 503 and the grouting port 501 can also be increased or decreased as needed. Thereby, the concrete injected at the lower part can fill the space at the beam-column joint while flowing to one end of the slurry. When the grouting is nearing completion, the injected concrete will be discharged from a higher place to ensure the beam-column joint. The space is filled. In terms of horizontal direction, when coagulation When the soil overflows from the slurry outlet, it means that the internal space corresponding to the side of the slurry outlet 503 is filled. At this time, the slurry outlet 503 of the overflow concrete is sealed, and after all the slurry outlets 503 are sealed, the beam is indicated. The space at the column joint is filled and grout is maintained until the vent hole 301 of the top surface 304 of the second structure 300 (refer to FIG. 3B) and the gap 306A of the insertion hole 306 overflow the concrete, indicating the space in the recess 308. And the gap 306A of the insertion hole 306 is filled, and then the grouting is stopped.

As shown in FIG. 5, the top surface 304 of the second structural body 300 has a plurality of leak stop plugs 600. The leakage stoppers 600 are disposed in pairs in the insertion holes, and are preferably disposed after assembling the column ribs 204. In terms of structure, the pair of stoppers 600 have a top surface 602 and a slope 604, wherein the outer diameter of the top surface 602 is larger than the diameter of the insertion hole 306, and the slope 604 is disposed at one end of the leakage stopper 600 and surrounds On top surface 602. In other words, the surrounding bevel 604 and the top surface 602 together form an extension, which facilitates removal of the leak stop 600 after the grouting is completed. In addition, the inner diameter of the leakage stopper 600 is not less than the diameter of the column 204, so that the leakage stopper 600 can be wrapped and slipped relative to the column 204. In the case of grouting operation, when the gap 306A of the insertion hole 306 is filled, the concrete will push up and stop the leakage plug 600 slightly away from the insertion hole 306, and all the leakage stoppers 600 are pushed up, and the leakage stopper can be removed. 600, complete the grouting operation. By means of the design of the leakage stopper 600, the stop timing of the grouting operation can be confirmed, and the grouting can be stopped when the internal space of the second structural body 300 is not completely filled, so as to improve the construction quality.

Different from the previous embodiment The plurality of trenches 310 on the bottom surface 302 are composed of a first trench 311 and a second trench 312. The first trench 311 is formed on the bottom surface 302 and surrounds the recess 308, for example, formed on the bottom surface 302 and forms a first trench 311 along four sides of the recess 308; the second trench 312 is formed on the surface 309 of the recess 308 and Connected to the venting opening 301, for example, one of the second grooves 312 in FIG. 7 is distributed along the direction a, and the other second groove 312 is distributed along the direction b. As mentioned above, the number and distribution of the grooves 310 can be adjusted according to the construction requirements. On the other hand, the grooves 310 can also improve the exhaust air efficiency by adjusting the overall distribution, for example, in the embodiment of FIG. The first trench 311 has a substantially square distribution, and the first trench 311 having a square distribution further has a second trench 312 symmetrically distributed from the four sides, which has a distribution pattern of the trench 310 as shown in FIG. With higher symmetry, better time control can be provided for the inflowing slurry during the grouting process to improve the air escape efficiency. With this design, when the second structure body 300 is combined with the first structure body 200 and then grouting, the air mixed in the grouting can be guided to the concave portion 308 by the groove 310, and then the groove 310 in the concave portion 308 is used. The air is directed to the venting opening 301 so that air does not remain at the beam joint.

In addition, a portion of the trench 310 away from the recess 308 extends around the insertion hole 306. For example, as shown in FIG. 7, the first trench 311 has four sides surrounding the recess 308, and the remaining portions are distributed in two perpendicular directions on two adjacent sides of the insertion hole 306 (for example, an L-shaped distribution is formed). ). Thereby, before the air is introduced into the recess 308, the direction of air circulation is guided from the periphery of the bottom surface 302 by the groove 310 surrounding the insertion hole 306, or the air is guided from the gap 306A in the insertion hole 306 (refer to the figure). 8) Escape.

As shown in the cross-sectional view of FIG. 8, after the second structural body 300 is hung on the first structural body 200, the bottom surface 302 is supported by the spacer 400, and then the template 500 is placed at the beam-column joint. In addition, the rib 204 passes through the insertion hole 306 and is connected to the rib 204 on the first structural body 200 by the splicing 206. Then prepare the grouting operation. After the space at the beam joint is filled, grouting is maintained until the vent hole 301 of the top surface 304 of the second structure 300 and the gap 306A of the insertion hole 306 overflow. For concrete, please refer to the perspective view of Figure 9. As shown in FIG. 9, the top surface 304 of the second structural body 300 has a plurality of leak stop plugs 600 disposed in pairs in the insertion holes. When the gap between the insertion holes is filled, the concrete will push up and stop the leakage plug 600 slightly away from the insertion hole. When all the leakage stoppers 600 are pushed up, the leakage stopper 600 can be removed to complete the grouting operation. By means of the design of the leakage stopper 600, the stop timing of the grouting operation can be confirmed, and the grouting can be stopped when the internal space of the second structural body 300 is not completely filled, so as to improve the construction quality. In summary, with the structure of the present invention, in addition to changing the structure of the concave portion in accordance with the shape of the beam-column joint, the groove of the surface of the bottom surface and the surface of the concave portion can be used to guide the air mixed during the grouting, so that the air does not Residual at the beam joint to increase the structural strength at the beam joint.
