Description

Technical Field

[0001] The utility model relates to the technical field of concrete feeding, in particular to a concrete feeding device. Background Art

[0002] In engineering construction, cast-in-place concrete structural members need to be poured to the lower opening of upper beams and other members. To ensure the quality of the later filled mortar, the height of the pouring opening left during formwork erection is small, about 50 - 60 mm. Coupled with the obstruction of the wooden beams and steel pipes for formwork reinforcement, it is difficult to pour concrete into the formwork. After inquiry, the utility model with the publication number of CN202380747U records a concrete pouring and feeding device, which includes a feeding hopper arranged on the upper part outside the structural column formwork and with the discharge port located at the upper opening of the structural column formwork, and an installation frame used to install and connect the feeding hopper with the structural column formwork. This device is convenient for pouring concrete into the formwork, but during the use process, on the one hand, the installation stability is poor and it cannot be firmly installed on the formwork. On the other hand, the concrete flows into the area to be poured along the bottom plate. During the flowing process, due to the inertia of the concrete, it will impact the formwork of the other structural column, resulting in the splashing of the concrete during feeding and even causing gaps in the fitting of the formwork. To address this technical problem, the utility model provides a concrete feeding device. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a concrete feeding device, hoping to overcome the problems described in the background art.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A concrete feeding device includes a feeding trough body arranged on the upper part of the formwork. The formwork encloses to form an area to be poured. The feeding trough body includes a bottom plate and side plates. The side plates are located on both sides of the bottom plate to form a trough-shaped structure. The bottom plate is inclined and a fastening mechanism for fixing on the upper part of the formwork is arranged at the bottom of the bottom plate. A splash-proof baffle is detachably connected at the lower port of the feeding trough body, and the splash-proof baffle is located directly above the area to be poured.

[0006] Further, a tension rod is penetrated between the two side formworks. Threads are arranged at both ends of the tension rod. A yoke and a nut sleeve are penetrated at both ends of the tension rod, and the nut sleeve is located outside the yoke.

[0007] Further, a plurality of wooden beams are arranged at intervals outside the formwork, and a steel pipe is clamped between the wooden beam and the yoke.

[0008] Further, the fastening mechanism includes a left clamping plate, a left rib plate, a right clamping plate and a right rib plate. The left clamping plate and the right clamping plate are welded to the bottom surface of the bottom plate, and there is a gap between the left clamping plate and the right clamping plate. A left rib plate is arranged between the included angle of the left clamping plate and the bottom plate, and a right rib plate is arranged between the included angle of the right clamping plate and the bottom plate.

[0009] Further, through holes are provided on both the left clamping plate and the right clamping plate, and screws are passed through the two through holes. A nut is welded to the through hole of the left clamping plate, and the screw is threadedly connected to the nut.

[0010] Further, connecting strips are provided on both sides of the splash-proof baffle. The connecting strips are connected to the side plates by screws. The splash-proof baffle is formed by bending a steel plate into three sides, and the upper edge of the splash-proof baffle is higher than the upper edge of the template.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model is provided with a feeding trough body with an inclined bottom plate, so as to facilitate the pouring of concrete into the area to be poured between the templates. A right clamping plate and a left clamping plate are arranged on the bottom surface of the bottom plate, and are fixed above the template by passing screws through them. Such a fixing method makes the installation more firm. A splash-proof baffle is also arranged on the feeding trough body, so that when the concrete flows down due to the inertia of the inclined surface, it will be blocked by the splash-proof baffle, preventing the concrete from colliding on the upper part of the template and causing the concrete to splash outwards and causing gaps at the enclosed part of the template. In addition, the tension rods and wooden beams provided in the present utility model can also prevent gaps from appearing in the templates. Description of the Drawings

[0017] Example 1:

[0018] Reference Figure 1-2 As shown, the present utility model provides a concrete feeding device, which includes a feeding trough body 7 arranged on the upper part of the formwork 1. The formwork 1 encloses a pouring area 1a. The feeding trough body 7 includes a bottom plate 72 and side plates 71. The side plates 71 are located on both sides of the bottom plate 72 to form a trough-shaped structure. Specifically, the side plates 71 and the bottom plate 72 are bent from steel plates. The bottom plate 72 is inclined, and a fastening mechanism 8 for fixing on the upper part of the formwork 1 is arranged at the bottom of the bottom plate 72. A splash-proof baffle 11 is detachably connected to the lower port of the feeding trough body 7. The splash-proof baffle 11 is located directly above the pouring area 1a. Further, the splash-proof baffle 11 is formed by bending a steel plate to form three sides, and the upper edge of the splash-proof baffle 11 is higher than the upper edge of the formwork 1. Thus, when the concrete flows down along the bottom plate 72, it will be blocked by the splash-proof baffle 11, preventing it from directly hitting the upper part of the formwork 1 and causing the concrete to splash outwards and creating gaps at the enclosure of the formwork 1. In addition, connecting strips 12 are arranged on both sides of the splash-proof baffle 11, and the connecting strips 12 are connected to the side plates 71 by screws 9.

The left clamping plate 83 and the right clamping plate 82 are welded to the bottom surface of the bottom plate 72, and there is a gap between the left clamping plate 83 and the right clamping plate 82, and this gap needs to be greater than or equal to the formwork thickness. A left rib plate 84 is arranged between the included angle of the left clamping plate 83 and the bottom plate 72, and a right rib plate 81 is arranged between the included angle of the right clamping plate 82 and the bottom plate 72, thereby increasing the support strength of the feeding trough body 7. Further, through holes are provided on both the left clamping plate 83 and the right clamping plate 82, and a screw 9 is passed through the two through holes. A nut 10 is welded to the through hole of the left clamping plate 83, and the screw 9 and the nut 10 are threadedly connected. During the connection process, the screw 9 passes through the upper part of the formwork 1.

[0022] During the construction process of this concrete feeding device, the specific method includes the following steps:

[0023] Step 1: Set up formwork 1, connect components such as tie rods 3 and yoke clamps 5, and leave a pouring opening with a height of 60 mm in formwork 1;

[0024] Step 2: Install the fastening mechanism 8 on the formwork 1 at the feeding port and tighten the screw 9 for fixation;

[0025] Step 3: Pour concrete into the feeding trough 7, and the concrete flows along the bottom plate 72 into the area to be poured. During this process, the concrete is blocked by the splash-proof baffle 11 to prevent it from splashing outside. The concrete is poured until it is flush with the formwork of the pouring opening, and the concrete pouring is completed;
