Technical Field
[0001] This utility model relates to the field of secondary structure infill wall and structural column casting technology in building engineering, specifically a wall panel pre-embedded infill wall grouting funnel. Background Technology
[0002] In existing technologies, the construction of infill walls mostly uses autoclaved aerated concrete (AAC) blocks. During construction, structural columns and frame columns must be provided according to specifications before concrete pouring. A small number of methods use formwork at the infill wall location, followed by lightweight concrete pouring to form the wall. Both of these methods require formwork to be erected at the corresponding locations before pouring, and funnel-shaped formwork to be installed above them to facilitate concrete pouring. After demolding, a triangular prism-shaped concrete block is left at the funnel-shaped formwork location, which needs to be manually chiseled. The chiseled surface is riddled with grooves, which seriously affects the construction quality of the infill wall and requires subsequent plastering repairs, resulting in a significant waste of labor, machinery, and materials, and delays in the construction period. Summary of the Invention
[0003] The purpose of this utility model is to solve the problems mentioned in the background art by designing a wall panel pre-embedded filling wall grouting funnel.
[0004] The technical solution of this utility model to achieve the above objectives is as follows:
[0005] A wall panel pre-embedded infill wall grouting funnel includes a funnel body, which comprises two side plates, a rear plate, a top plate, and a sloping front plate. The side plates are located on both sides of the funnel body, the sloping front plate is located at the lower front of the funnel body, the rear plate is located at the rear of the funnel body, and the top plate is located on the upper side of the funnel body. The side plates, sloping front plate, rear plate, and top plate are welded to form the funnel body. Additional funnel reinforcement bars extending outwards are welded and fixed to the side plates, rear plate, top plate, and sloping front plate of the funnel body. A funnel baffle is provided on the upper front of the funnel body, and the funnel baffle is bolted to the two side plates. A grouting hole is opened at each of the four corners of the funnel baffle. Internal reinforcing bars extending downwards are welded and fixed to the top plate inside the funnel body.
[0006] Furthermore, the side plate is composed of a rectangular steel plate and a triangular steel plate. The rectangular steel plate is fixedly connected to the upper plate and the rear plate respectively. The triangular steel plate is located at the lower front side of the rectangular steel plate and extends forward. The triangular steel plate is a right triangle and its hypotenuse is fixedly connected to the inclined front plate. The triangular steel plate and the inclined front plate together form the funnel opening of the funnel body.
[0007] Furthermore, the vertical projection height of the inclined front plate is consistent with the thickness of the main floor slab.
[0008] Furthermore, the funnel-shaped additional reinforcement on the outer side of the rear plate has a hook-shaped end and is connected to the reinforcement in the upper shear wall.
[0009] Furthermore, the funnel baffle is provided with bolt holes, which are located at the four corners of the funnel baffle, 5mm from the edge of the steel plate. The funnel baffle is provided with fixing bolts, and the funnel baffle and the side plates on both sides of the funnel body are vertically fixed to the upper front side of the funnel body by fixing bolts passing through the bolt holes.
[0010] Furthermore, a straight threaded sleeve is provided on the funnel-shaped additional rib on the outer side of the upper plate, and the straight threaded sleeve is fixedly installed on the funnel-shaped additional rib on the outer side of the upper plate.
[0011] Furthermore, the side plate, the inclined front plate, the rear plate, the upper plate, and the funnel baffle are all made of 10mm thick steel plate.
[0012] Furthermore, the grouting holes at the four corners of the funnel baffle are 20mm from the edge, and the radius of the grouting holes is 10mm.
[0013] This utility model provides a wall panel-embedded infill wall grouting funnel. Through structural design, the funnel body and additional reinforcement bars are pre-embedded in corresponding positions before the lower main beam and slab are poured. The outer edge of the upper plate of the funnel body is flush with the surface of the upper shear wall. The main floor slab reinforcement can be connected to the additional reinforcement bars welded to the inclined front plate of the funnel body. During the pouring of the lower main structure, the floor slab elevation is flush with the upper end of the funnel body. During the construction of the upper main structure, the reinforcement bars of the upper shear wall or the upper infill wall can be connected to the additional reinforcement bars welded to the upper and rear plates of the funnel body. When the shear wall is supported by formwork, the outer edge of the funnel body is exposed. Before the upper main structure is poured, the funnel baffle is fixed to the outer edge of the funnel to prevent shear wall concrete from flowing into the funnel.
[0014] After the main structure is completed and before the secondary structure construction begins, reinforcing bars are first tied to the corresponding parts of the lower infill wall, which can be connected to the built-in reinforcing bars on the lower surface of the upper slab. Formwork is then erected. Next, the funnel baffle is removed, and grout is poured into the lower infill wall through the funnel opening, while simultaneously vibrating the grout. Pouring is stopped when the poured surface is flush with the upper edge of the funnel opening. Finally, the funnel baffle is reinstalled and fixed, and grouting is performed through the grouting hole at the lower end of the funnel baffle. Grouting is stopped when grout flows out of the upper grouting hole, completing the construction. The funnel baffle can be removed for reuse.
[0015] Compared with existing technologies, this utility model avoids the waste of manpower and material resources caused by traditional chiseling processes by changing the shape design of the grouting funnel and its application process. It provides good construction conditions for the popularization of infill wall pouring construction, improves construction efficiency, and saves construction costs. Attached Figure Description

[0026] like Figures 1 to 7As shown, this embodiment provides a wall panel pre-embedded filling wall grouting funnel, including a funnel body 1. The funnel body 1 includes two side plates 4, a rear plate 5, an upper plate 6, and an inclined front plate 7. The side plates 4 are located on both sides of the funnel body 1, the inclined front plate 7 is located at the lower part of the front side of the funnel body 1, the rear plate 5 is located at the rear side of the funnel body 1, and the upper plate 6 is located on the upper side of the funnel body 1. The side plates 4, inclined front plate 7, rear plate 5, and upper plate 6 are welded to form the funnel body 1. The side plates 4, rear plate 5, upper plate 6, and inclined front plate 7 of the funnel body 1 are all welded and fixed with outwardly extending funnel additional ribs 2. A funnel baffle 3 is provided on the upper front side of the funnel body 1. The funnel baffle 3 is fixed to the two side plates 4 by bolts. A grouting hole 11 is opened at each of the four corners of the funnel baffle 3. An internally installed reinforcing bar 9 extending downward is welded and fixed to the upper plate 6 inside the funnel body 1.
[0027] In this embodiment, the side plate 4 is composed of a rectangular steel plate 13 and a triangular steel plate 14. The rectangular steel plate 13 is fixedly connected to the upper plate 6 and the rear plate 5 respectively. The triangular steel plate 14 is located at the lower front side of the rectangular steel plate 13 and extends forward. The triangular steel plate 14 is a right triangle and its hypotenuse is fixedly connected to the inclined front plate 7. The triangular steel plate 14 and the inclined front plate 7 together form the funnel opening of the funnel body 1.
[0028] In this embodiment, the vertical projection height of the inclined front plate 7 is consistent with the thickness of the main floor slab.
[0029] In this embodiment, the funnel-shaped auxiliary reinforcement 2 on the outer side of the rear plate 5 has a hook-shaped end and is connected to the reinforcement in the upper shear wall 15. The hook-shaped end of the funnel-shaped auxiliary reinforcement 2 makes it easier to connect with the shear wall reinforcement.
[0030] In this embodiment, the funnel baffle 3 is provided with bolt holes 12, which are located at the four corners of the funnel baffle 3, 5mm from the edge of the steel plate. The funnel baffle 3 is provided with fixing bolts 10, and the funnel baffle 3 and the side plates 4 on both sides of the funnel body are vertically fixed to the upper front side of the funnel body 1 by the fixing bolts 10 passing through the bolt holes 12. By fixing the funnel baffle 3 vertically to the outside of the funnel opening with the fixing bolts 10 passing through the bolt holes 12, a closed system is formed, preventing concrete from entering the funnel and contaminating the infill wall pouring area during the pouring of the main wall panel.
[0031] In this embodiment, a straight threaded sleeve 8 is provided on the funnel-shaped auxiliary reinforcement 2 on the outer side of the upper plate 6, and the straight threaded sleeve 8 is fixedly installed on the funnel-shaped auxiliary reinforcement 2 on the outer side of the upper plate 6. The straight threaded sleeve 8 makes it easier to connect with the main wall reinforcement.
[0032] In this embodiment, the side plate 4, the inclined front plate 7, the rear plate 5, the upper plate 6, and the funnel baffle 3 are all made of 10mm thick steel plate.
[0033] In this embodiment, the grouting holes 11 at the four corners of the funnel baffle 3 are 20mm from the edge, and the radius of the grouting holes 11 is 10mm.
[0034] In this embodiment, the funnel body 1 is welded together from side plates 4 on both sides, a front inclined plate 7 at the front end of the funnel, a rear plate 5 at the rear end of the funnel, and an upper plate 6 on the top. All these baffles are made of 10mm thick steel plates. The side plates 4 are welded together from a rectangular steel plate 13 and a right-angled triangular steel plate 14. One rectangular side is located at the rear end of the funnel and connects to the upper plate 6 and the rear plate 5, respectively. The other right-angled triangular side is located at the front end of the funnel, with its hypotenuse connected to the front inclined plate 7. One right-angled side is welded to the rectangular side, and the other right-angled side forms the upper edge of the funnel opening. Two bolt holes are provided at the front edges of each of the two side plates 4. 12; The additional reinforcing bar 2 of the funnel is a steel bar welded around the funnel and on the upper steel plate. It is used to connect with the steel bars in the wall panel components in the original design drawing. Its specifications can be flexibly changed according to the design requirements. The straight threaded sleeve 8 on the additional reinforcing bar 2 of the funnel body 1 can be more conveniently connected with the main wall steel bars; The funnel baffle 3 is made of 10mm steel plate. Its upper end is connected to the outer edge of the upper plate 6, and its two sides are connected to the side plates 4 on both sides of the funnel body 1. It is vertically fixed to the outside of the funnel opening by fixing bolts 10 passing through bolt holes 12 to form a closed system, so as to prevent concrete from entering the funnel when the main wall panel is poured and contaminating the pouring part of the infill wall.
[0035] During construction, such as Figure 6 and Figure 7 As shown, before pouring the lower main beam and slab, the funnel body 1 and the funnel additional reinforcement 2 are pre-embedded in the corresponding positions. The outer edge of the upper plate 6 of the funnel body 1 is flush with the surface of the upper shear wall 15. The main floor slab reinforcement can be connected to the funnel additional reinforcement 2 welded on the inclined front plate 7 of the funnel body 1. When the lower main structure is poured, the elevation of the lower main floor slab 16 is flush with the upper end of the funnel body 1. When the upper main structure is constructed, the reinforcement of the upper shear wall 15 or the reinforcement of the upper infill wall can be connected to the funnel additional reinforcement 2 welded on the upper plate 6 and rear plate 5 of the funnel body 1. The ends of the funnel additional reinforcement 2 set on the outer side of the rear plate 5 are made into hooks to facilitate the connection with the shear wall reinforcement. When the shear wall is supported by formwork, the outer edge of the funnel body 1 is exposed. Before the upper main structure is poured, the funnel baffle 3 is fixed on the outer edge of the funnel to prevent the shear wall concrete from flowing into the funnel.
[0036] After the main structure construction is completed and before the secondary structure construction begins, steel bars are first tied to the corresponding parts of the lower infill wall 17, which can be connected to the built-in steel bars 9 set on the lower surface of the upper slab 6. The infill wall formwork 18 is then erected. Next, the funnel baffle 3 is removed, and grout is poured into the lower infill wall 17 through the funnel opening, while simultaneously vibrating the grout. Pouring is stopped when the poured surface is flush with the upper edge of the funnel opening. Finally, the funnel baffle 3 is fixed in place with fixing bolts 10, and grouting is performed through the grouting hole 11 at the lower end of the funnel baffle 3. Grouting is stopped when grout flows out of the upper grouting hole 11, completing the construction. The funnel baffle 3 can be removed for reuse.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
