Description

Technical Field

[0001] The utility model relates to the field of pouring construction of vertical fully sealed concrete structures such as retaining plates between piles, and more specifically to a wedge-shaped pouring mould. Background Art

[0002] Deep foundation pit projects are currently more common in urban construction. As a key quality control item of deep foundation pit projects, the foundation pit support system is of great significance to the safety guarantee during the project implementation stage.

[0003] The retaining plate between piles is a frequently used and vital component in the deep foundation pit support system. Therefore, the concrete pouring quality of the retaining plate between piles directly affects the stability of the entire support system. During the "reverse construction" process of foundation pit support, the concrete joints between the previous unit retaining plate and the next unit retaining plate are often not densely poured and not full, resulting in the entire unit retaining plate not being able to effectively become a whole, and often water seepage and other poor quality hazards appear at the joints. The common way to deal with this problem is to perform secondary roughening, mold sealing, and grouting on the joints. This treatment method not only directly affects the progress of the project, but also poses a greater safety risk, and also increases the investment in construction costs.

[0004] In order to ensure that the retaining plates between piles and similar concrete components can be poured densely and fully at the concrete joints at one time, so as to ensure the entity quality of the retaining plates between piles and similar concrete components, a low-cost and turnaround construction mold is needed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a wedge-shaped casting mold.

[0006] The technical solution of this utility model is as follows:

[0007] A wedge-shaped casting mold comprises a feed hopper and a head plate; the feed hopper is a hollow structure, the top opening is the feed port, and the side is the discharge port; the bottom surface of the feed hopper is designed to be an inclined surface to facilitate the flow of concrete; a connecting plate is installed at the discharge port, a slide groove is provided in front of the connecting plate, and the head plate can slide from the bottom of the slide groove to the top, and mounting holes are provided at the four corners of the connecting plate.

[0008] The top of the head plate is designed with an acute angle, and the bottom of the head plate is designed with a boss for facilitating application of force.

[0009] A lower drag rod is placed on the bottom surface of the feed hopper, and the lower drag rod is fixed on the steel pipe frame.

[0010] The connecting plate is fixed by fixing bolts and nuts.

[0011] Technical effects and advantages of the utility model:

[0012] The use of this device can significantly improve the quality of concrete joints. The mold is stable, reliable, and can be used in a turnover manner. After casting and forming, the finished product quality and appearance quality are good, which avoids rework and repair, speeds up the construction progress, and reduces construction costs.

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0020] A wedge-shaped casting mold comprises a feed hopper 1 and a head plate 2; the feed hopper is a hollow structure, the top opening is a feed port 11, and the side is a discharge port 12; the bottom surface 13 of the feed hopper is designed to be an inclined surface to facilitate the flow of concrete; a connecting plate 3 is installed at the discharge port, a slide groove 4 is opened in front of the connecting plate, and the head plate can slide from the bottom of the slide groove to the top, and the four corners of the connecting plate are provided with mounting holes 5.

[0021] Furthermore, the top of the head plate 2 is designed with an acute angle 21, and the bottom of the head plate is designed with a boss 22 for facilitating force application.

[0022] Furthermore, a lower drag rod 6 is placed on the bottom surface of the feed hopper, and the lower drag rod is fixed on the steel pipe frame.

[0023] Furthermore, the connecting plate is fixed by fixing bolts 7 and nuts 8. Embodiment 2

[0024] like Figure 4-6As shown, the implementation method and features are described as follows:

[0025] Step 1, pre-embedded fixing bolts: During the process of tying the reinforcement bars of the retaining plate between piles, install the fixing bolts 7 for installing and fixing the wedge-shaped mold.

[0026] Step 2: Install the wedge-shaped mold: When installing the template for the retaining wall between piles, leave a hole slightly smaller than the wedge-shaped mold at the corresponding position of the wedge-shaped mold for concrete pouring. The templates of the remaining parts extend more than 20 cm to the last poured retaining wall unit.

[0027] Step 3: Install and reinforce the wedge-shaped mold: Align the installation notches around the wedge-shaped mold with the embedded bolts for installation. After the four bolts successfully pass through the notches of the wedge-shaped mold, install the bolt gaskets and tighten the nuts. During the template reinforcement process, the beam support is reinforced close to the bottom of the wedge-shaped mold.

[0028] Step 4: Concrete sealing: After the wedge-shaped mold and template are reinforced, align the wedge-shaped mold to pour concrete. After pouring, apply butter to the lower end plate of the wedge-shaped mold, push and pull upwards and back and forth until the template opening is completely closed.

[0029] Step 5: Remove the wedge-shaped mold: After the concrete is initially shaped, remove the mold immediately to facilitate cleaning of the concrete inside the mold.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
