Description

Technical Field

[0001] This utility model relates to a material outlet structure for composite slabs, belonging to the field of building construction technology. Background Technology

[0002] In order to enable the temporary and rapid passage of cables or pipes between upper and lower floors in building floor slabs, a material discharge cylinder is installed on the assembled monolithic floor slab composed of precast composite floor slabs and cast-in-place floor slabs to present a material discharge port.

[0003] When not in use, the discharge port needs to be sealed. The existing technology for sealing the discharge port can be found in Chinese Patent Publication No. CN219931706U. The protective cover plate is opened by rotating upward to seal the discharge port. However, a cast-in-place floor slab needs to be poured on the precast composite floor slab. The protective cover plate needs to be removed when the cast-in-place floor slab is poured, thus losing its sealing function. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a material discharge port structure for composite plates.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a material discharge port structure for composite plates, comprising: Precast composite floor slabs, with conical holes provided on the precast composite floor slabs; The material discharge cylinder is a cone-shaped cylinder that forms a discharge port. The material discharge cylinder is clamped and placed in the cone-shaped hole of the precast composite floor slab. Cast-in-place floor slabs are built on top of precast composite floor slabs.

[0007] The material discharge cylinder penetrates vertically within the cast-in-place floor slab and the precast composite floor slab.

[0008] The top horizontal cross-section of the discharge cylinder has an opening, and a sealing plate is slidably inserted into the opening. The sealing plate is pushed into the opening of the discharge cylinder in a horizontal direction, and the sealing plate seals the inside of the discharge cylinder.

[0009] The closed plate is fixedly connected to a curved section, and a locking pin is fixed to the outside of the discharge cylinder. The curved section and the locking pin are limited by the locking pin, and the curved section undergoes slight elastic deformation at this time, pressing against the bottom surface of the locking pin.

[0010] Both the curved section and the locking pin seat are provided with through holes for the locking pin to pass through, and the bottom of the locking pin abuts against the sealing plate.

[0011] The beneficial effects of this utility model are as follows: When using concrete to construct cast-in-place floor slabs on precast composite floor slabs, the material discharge cylinder with an internal closed plate is inserted into the conical hole set on the precast composite floor slab, which solves the problem that the protective cover plate that rotates upward and opens needs to be removed during the casting of cast-in-place floor slabs and loses its sealing function.

[0012] Figure 1 This is a schematic diagram of the main sectional view of this utility model; In the diagram: 1-cast-in-place floor slab; 2-precast composite floor slab; 3-material discharge cylinder; 31-closed slab; 32-bending section; 33-pin seat; 34-pin. Detailed Implementation

[0013] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0014] like Figure 1 As shown.

[0015] The present application discloses a composite plate feed port structure, comprising: The precast composite floor slab 2 is located below, and the cast-in-place floor slab 1 is cast on top of the precast composite floor slab 2 by pouring concrete. A discharge cylinder 3 is vertically installed in both the cast-in-place floor slab 1 and the precast composite floor slab 2, forming a discharge port. The discharge cylinder 3 is a cone, and the precast composite floor slab 2 has a conical hole for the discharge cylinder 3 to be fitted and placed. After the cast-in-place floor slab 1 is poured, the discharge cylinder 3 is vertically positioned within the cast-in-place floor slab 1.

[0016] When the cast-in-place floor slab 1 is not poured, the top horizontal cross-section of the material discharge cylinder 3 installed in the precast composite floor slab 2 has an opening. A closing plate 31 is slidably inserted into the opening. The closing plate 31 is pushed horizontally into the opening of the material discharge cylinder 3, sealing the interior of the material discharge cylinder 3. A curved section 32 is integrally fixed to the closing plate 31. A locking pin seat 33 is welded to the outside of the material discharge cylinder 3. The curved section 32 and the locking pin seat 33 are limited by a locking pin 34. At this time, the curved section 32 undergoes slight elastic deformation and abuts against the bottom surface of the locking pin seat 33. Both the curved section 32 and the locking pin seat 33 have through holes for the locking pin 34 to pass through. The bottom of the locking pin 34 abuts against the closing plate 31.

[0017] When the closing plate 31 is pulled out from the discharge cylinder 3, the curved section 32 can hook onto the top edge of the discharge cylinder 3.

[0018] When pouring concrete onto the precast composite floor slab 2 to construct the cast-in-place floor slab 1, the discharge cylinder 3, with an internal sealing plate 31, is fitted into a conical hole on the precast composite floor slab 2. This solves the problem that the protective cover plate, which rotates upwards and opens, needs to be removed during the pouring of the cast-in-place floor slab, thus losing its sealing function. After the cast-in-place floor slab 1 has reached initial setting, the discharge cylinder 3 is removed. The discharge cylinder 3, with the sealing plate 31 inserted internally, is then pushed into the precast composite floor slab 2.
