[0023] Example 1
[0024] A concrete conveying device for improving the concrete vibration quality at the root of the post-casting belt of the exterior wall, such as Figure 1~Figure 2 As shown, it includes a reinforced concrete precast plate 3 installed in advance on the water-facing surface of the post-cast zone of the basement outer wall, a concrete conveying and vibrating port 4 is provided on the reinforced concrete precast plate 3, and an inclined baffle is provided on the reinforced concrete precast plate 3. The inclined baffle is arranged on one side of the concrete conveying and vibrating port 4, and the lower end of the inclined baffle overlaps with the lower end of the concrete conveying and vibrating port 4. The inclined baffle is inclined outwardly arranged, and a cable is connected between the inclined baffle and the reinforced concrete precast plate 3 around the concrete conveying and vibrating port 4; the concrete conveying and vibrating port 4 is used for the vibrating rod to extend from the concrete conveying and vibrating port 4 to vibrate the concrete and improve the vibration quality. After the concrete pouring is completed, the steel plate 5 is pushed inward along the concrete conveying and vibrating port 4 to close the concrete conveying and vibrating port 4 on the reinforced concrete precast plate 3. The cable has a certain strength and will not break during use.
[0025] Furthermore, the size of the inclined baffle is consistent with the size of the concrete conveying and vibrating opening 4 ; after pouring the concrete, the inclined baffle is closed with the concrete conveying and vibrating opening 4 to seal the concrete conveying and vibrating opening 4 .
[0026] Example 2
[0027] The cable is further limited on the basis of Example 1, and the performance of Example 2 after the limitation is better.
[0028] There are 4 cables, and the four corners of the inclined baffle are connected to the reinforced concrete precast plate 3 through 4 groups of cables respectively; the length of the cable connected to the upper end of the inclined baffle is longer than the cable connected to the lower end of the inclined baffle.
[0029] Furthermore, one end of the anchoring point of the cable is on the steel bar of the reinforced concrete precast slab 3 , and the other end is on the four corners of the steel plate 5 .
[0030] Furthermore, the inclined baffle is a steel plate 5 , and the cable is made of a steel wire 6 .
[0031] The angle α between the inclined baffle and the reinforced concrete precast slab 3 is (30°~50°), and the optimal angle of α is 45°.
[0032] Furthermore, the post-cast strip of the basement outer wall is closed, and arc-shaped plastering treatment is performed on the contact point between the reinforced concrete precast slab 3 and the basement outer wall 1.
[0033] Furthermore, the height of the concrete delivery and vibration port 4 is located at the reinforced concrete precast slab 3 at 1.2m-1.5m.
[0034] Furthermore, the size of the concrete delivery and vibration port 4 is (30cm~40cm)*(30cm~40cm); the size is sufficient to allow the sky pump to extend into and meet the concrete delivery rate, thereby preventing concrete from segregating due to excessive delivery height.
[0035] Furthermore, concrete anti-leakage blocks are placed between the inclined baffle and the basement outer wall 1 on both sides of the concrete delivery and vibration port 4 to prevent concrete from leaking out during pouring.
[0036] Furthermore, the concrete anti-leakage block is an isosceles right-angled triangle wooden block.
[0037] Working principle of the utility model: The utility model relates to a method for improving the concrete vibration quality at the root of the exterior wall post-casting belt and a concrete conveying device, which is to install a reinforced concrete prefabricated plate on the exterior wall post-casting belt of the basement, and open a 30cm*30cm concrete conveying and vibrating hole on the reinforced concrete prefabricated plate 1.2m-1.5m above the ground; when pouring concrete in the exterior wall post-casting belt, move the sky pump to the top of the concrete conveying and vibrating hole to convey concrete through the inclined baffle and the concrete conveying and vibrating hole, which can effectively prevent the concrete from segregating due to excessive conveying height; at the same time, the vibrating rod can also be extended from the conveying and vibrating hole to vibrate the concrete, which can effectively improve the bottom concrete vibration effect and improve the pouring quality of the exterior wall post-casting belt.
