Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a rainwater head mounting structure and mounting method for single-steel-plate concrete structure. BACKGROUND

[0002] The rainwater head is provided in the roof gutter to drain the rainwater accumulated in the gutter. The rainwater head has a flow regulating grid device, which can quickly drain the roof rainwater, the grid has a flow regulating effect, avoids forming a large vortex, stabilizes the water level in front of the head, reduces air entrainment, can quickly drain the roof rainwater and snow water, and can effectively block larger debris.

[0003] The conventional installation method of the rainwater head mainly relies on the "09S302 Rainwater Head Selection and Installation Atlas", which mainly includes two installation methods of the rainwater head. The first method is suitable for the case where the rainwater head is installed on a steel plate gutter structure, and the second method is suitable for the case where the rainwater head is installed on a concrete structure. However, there are cases where the rainwater head is installed on a single-steel-plate concrete structure in some projects. The single-steel-plate concrete structure is a new type of concrete structure that uses a steel plate as a formwork and uses high-strength steel mesh and thin-walled concrete. Compared with the traditional formwork method, the single-steel-plate concrete has the advantages of fast construction speed, good durability, and wider applicability, and has been widely used in the field of building construction.

[0004] In the single-steel-plate concrete structure, if the installation method in the atlas is used, the rainwater head is directly welded on the steel plate. First, the concrete compaction cannot be performed using a concrete vibrator due to the influence of the steel reinforcement surface layer, and the rainwater head cannot be fixed after being wrapped with a wire mesh, which may cause loosening. In addition, the concrete is not poured from both sides to the middle during pouring, and the final pouring of the concrete does not achieve the desired effect. Second, the concrete structure needs to be watered during curing, which prevents immediate waterproofing work. Before waterproofing, rainwater or water required for curing may seep through the small gaps in the concrete plate between the steel plate and the concrete plate, causing water leakage and affecting the overall construction quality.

[0005] Based on the above defects, the present application provides a rainwater head mounting structure and mounting method for single-steel-plate concrete structure to solve the problems of the prior art. SUMMARY

[0038] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0039] The present embodiment provides a rainwater head mounting structure for a single-steel-plate concrete structure, which is Figure 1 Fig. 1 is a structural schematic diagram of a rainwater head mounted in a steel-plate concrete structure, and a rainwater head mounting structure 3 is used to mount a rainwater head 1 in a steel-plate concrete structure 2, from Figure 1 As can be seen from Fig. 1, the steel-plate concrete structure 2 is composed of a concrete layer 21 and a steel body 22 held at the lower end of the concrete layer 21, and the steel body 22 and the concrete layer 21 form a gutter 23 for collecting rainwater. The rainwater head 1 has a main body part 11, a reducing part 12 connected to the lower end of the main body part 11, and a head part 13 placed at the upper end of the main body part 11, and a step face is formed at the joint of the main body part 11 and the reducing part 12.

[0040] Specifically, the mounting structure 3 includes a first through hole 31 formed in the steel body 22, which allows the reducing part 12 of the rainwater head 1 to pass through but not the main body part 11 of the rainwater head 1; a second through hole 32 formed in the concrete layer 21, which is connected to the first through hole 31 and allows the main body part 11 of the rainwater head 1 to pass through but not the head part 13 of the rainwater head 1, i.e., the head part 13 of the rainwater head 1 is exposed in the gutter 23 to facilitate the guiding of rainwater in the gutter 23; and a filler for sealing the gap between the rainwater head 1 and the steel-plate concrete structure 2.

[0041] Further, the mounting structure 3 further includes a closure 33 fixedly arranged at the first through hole 31, which is a cylindrical column made of steel material and welded to the inner edge side of the first through hole 31. The closure 33 extends from the first through hole 31 into the second through hole 32 to support the step face formed by the rainwater head 1, so that a first space 34 for pouring the filler is formed between the inner wall surface of the second through hole 32 and the rainwater head 1, and a second space 35 for placing the filler is formed between the closure 33 and the reducing part 12 of the rainwater head 1.

[0042] Further, the filler in the second space 35 is oil mud 36.

[0043] Further, the filler in the first space 34 is concrete 37 and a leak-stopper 38, and the concrete 37 is located at the lower end of the leak-stopper 38, wherein the concrete 37 is used as a base, and the remaining space is filled with the leak-stopper 38.

[0044] Further, the waterproof glue is coated on the end of the leak stopper 38 flush with the bottom surface of the gutter 23, and a cement surface is coated on the surface of the waterproof glue.

[0045] The rainwater head mounting structure for the single-steel-plate concrete structure is mounted by the following mounting method.

[0046] Specifically, the mounting method comprises the steps of: Figure 1

[0047] S1. Reserving a first through hole 31 for the reduced-diameter part 12 of the rainwater head 1 to pass through on the position where the rainwater head 1 is mounted on the steel body 22. After the steel body 22 is mounted, the reinforcing bars at the first through hole 31 are cut off. The shape cut off is 100 mm larger than the panel of the rainwater head 1, which facilitates the later construction.

[0048] S2. Placing the extruded sheet on the shape cut off on the upper end of the first through hole 31. A plurality of extruded sheets are overlapped and placed together. The extruded sheets completely cover the first through hole 31, and the height of the extruded sheets exceeds the reinforcing surface layer. Then, the extruded sheets are fixed to ensure their stability.

[0049] S3. Pouring the concrete layer 21 in the sky pit formed by the steel body 22. The gutter 23 for rainwater collection is formed on the upper end of the concrete layer 21. Then, the extruded sheets are knocked and removed. The second through hole 32 is formed in the concrete layer 21. The second through hole 32 is communicated with the first through hole 31 and the gutter 23. The residual materials in the knocked area are cleaned to facilitate the chiseling treatment of the inner wall of the second through hole 32 in the subsequent construction.

[0050] S4. Fixing the welded closure 33 at the first through hole 31. The closure 33 is a cylindrical steel pipe. One end of the closure 33 extends into the second through hole 32. The welded part is rusted, painted, and subjected to a small-range water test to avoid the water leakage problem at the welded position.

[0051] S5. Placing the rainwater head 1 so that the reduced-diameter part 12 of the rainwater head 1 passes through the first through hole 31. The main body part 11 is placed in the second through hole 32, and the head part 13 is exposed in the gutter 23. The closure 33 limits the step surface and forms the first space 34 between the inner wall of the second through hole 32 and the rainwater head 1, which is convenient for pouring the filling material. The closure 33 and the reduced-diameter part 12 of the rainwater head 1 form the second space 35 for placing the filling material.

[0052] S6. Filling the first space 34 and the second space 35.

[0053] Step S6a. Filling the jute yarn in the second space 35 as much as possible.

[0054] ​Step S6b. First fill the first space 34 with concrete 37, then fill it with sealant 38 until the sealant 38 is flush with the bottom of the gutter 23. Specifically, first use high-strength concrete to lay the bottom layer and compact it as much as possible. Then prepare the sealant and pour it into the first space 34. Stop pouring when it reaches 3 / 4 of the height of the first space 34. After the concrete has completely solidified, conduct a water tightness test. Then pour in the remaining 1 / 4 of the height of the sealant in the first space 34 and compact it.

[0055] S7. After the Leak-Stopping Agent 38 dries, apply waterproof adhesive to the surface of the Leak-Stopping Agent 38. Specifically, connect the concrete surface, the Leak-Stopping Agent, and the rainwater hopper panel as one unit to prevent any possibility of seepage through the joints or to the bottom before applying the waterproof layer. Ensure that the waterproof adhesive dries before brushing on a layer of cement to avoid exposure to sunlight and damage to the waterproof adhesive.

[0056] S8. Finally, conduct a water tightness test to ensure construction quality.
