Description

Technical Field

[0001] This utility model relates to the field of composite cavity shear wall production technology, and in particular to a concrete placing device for composite cavity shear wall production. Background Technology

[0002] Composite cavity shear wall is a modern building technology mainly used in prefabricated buildings. It has many structural and construction advantages. Composite cavity shear wall consists of two layers of precast concrete slabs and a cavity in the middle. This structural form allows it to maintain a relatively light weight while having good structural stability and load-bearing capacity.

[0003] Referring to the utility model patent with authorized publication number CN211682771U, a concrete placing device for producing composite cavity shear walls is disclosed, including a concrete hopper, a joint, a concrete conduit, and a concrete conveying device; the concrete hopper includes an upper opening with a large cross-sectional area and a lower opening with a smaller area, the concrete conveying device is disposed at the lower opening, and the concrete conveying device is adapted to discharge the concrete in the concrete hopper from the lower opening; one end of the joint is connected to the lower opening, and the other end is connected to the concrete conduit.

[0004] The aforementioned patent cannot vibrate the interior of the composite cavity shear wall during production, resulting in insufficient compaction of the internal pouring layer during casting. Consequently, the structural strength of the cast composite cavity shear wall after casting is difficult to meet design requirements. To solve the above problems, we propose a concrete placing device for the production of composite cavity shear walls. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete placing device for the production of composite cavity shear walls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete placing device for producing composite cavity shear walls includes a production base on which a composite cavity shear wall is placed. A top plate is provided on the upper side of the composite cavity shear wall. A synchronous motor is fixedly installed on the top plate. A stranded wheel is fixedly installed on the output end of the synchronous motor. A steel wire rope is wound on the stranded wheel. A mounting plate is fixedly connected to the lower end of the steel wire rope. A motor is installed on the mounting plate. A flexible shaft is fixedly installed on the output end of the motor. A vibrator is fixedly installed at the bottom of the flexible shaft. A sealing plate is fixedly installed at the bottom of the mounting plate. A vibration damping mechanism is provided on the mounting plate. The vibration damping mechanism includes a support groove and a support tube. A sliding cover is slidably installed on the support groove. Several springs are fixedly connected between the inner sides of the support groove and the sliding cover. The support tube is screwed onto the mounting plate. The flexible shaft passes through the support tube. A sponge tube sleeve is fitted between the inner wall of the support tube and the flexible shaft.

[0008] Preferably, the composite cavity shear wall includes a first wall panel and a second wall panel, and connecting steel bars are welded between the first wall panel and the second wall panel.

[0009] Preferably, mounting bases are fixedly connected to both sides of the top plate.

[0010] Preferably, the top plate of the synchronous motor is symmetrically arranged with two sets.

[0011] Preferably, slide rods are symmetrically fixedly installed on the upper side of the mounting plate, and the upper end of the slide rods slides through to the upper side of the top plate.

[0012] Preferably, the sealing plate is installed at a position corresponding to the position of the connecting steel bar, and the distance between the inner side of the sealing plate and the outer side of the connecting steel bar meets the requirements for the thickness of the protective layer.

[0013] Preferably, a concrete feeding pipe is installed on the mounting plate, and the concrete feeding pipe extends to the bottom of the mounting plate.

[0014] Preferably, a damper is provided on the inner side of the spring, and a sealing ring is provided at the screw interface between the support tube and the bottom of the mounting plate.

[0015] Compared with related technologies, the concrete placing device for producing composite cavity shear walls proposed in this utility model has the following beneficial effects:

[0016] In this utility model, a concrete placing device for producing composite cavity shear walls is described. When connecting and pouring the composite cavity shear wall, the mounting plate is lowered onto the upper side of the composite cavity shear wall. The sealing plate at the bottom of the mounting plate seals the inner connecting steel bars of the composite cavity shear wall, forming a formwork effect. Concrete is then introduced into the inner side of the sealing plate, and simultaneously, the motor is started, driving a vibrator via a flexible shaft to vibrate the concrete inside the sealing plate, expelling air bubbles and increasing the density of the concrete. This ensures the structural strength of the formed composite cavity shear wall and improves its practicality. Furthermore, an added vibration damping mechanism, through the spring between the support groove and the sliding cover, and the sponge sleeve inside the support tube, reduces the vibration generated by the motor and the flexible shaft, weakening the impact of vibration on the entire mounting plate. This prevents leakage from the sealing plate due to vibration during pouring, thus avoiding disruption to the entire pouring process and further improving practicality. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-4 Please refer to the following: Figures 1-4 ,in, Figure 1This is a three-dimensional structural diagram of a concrete placing device for producing composite cavity shear walls proposed in this utility model. Figure 2 This is a three-dimensional structural diagram of a composite cavity shear wall, which is a concrete placing device for producing composite cavity shear walls according to the present invention. Figure 3 This is a partial three-dimensional structural diagram of a concrete placing device for producing composite cavity shear walls proposed in this utility model. Figure 4 for Figure 3 Enlarged schematic diagram of the internal cross-section structure of section A. A concrete placing device for producing composite cavity shear walls includes: a production base 1, on which a composite cavity shear wall 2 is placed; a top plate 3 is provided on the upper side of the composite cavity shear wall 2; a synchronous motor 4 is fixedly installed on the top plate 3; two sets of synchronous motors 4 are symmetrically arranged on the top plate 3; a stranded wheel 5 is fixedly installed on the output end of the synchronous motor 4; a steel wire rope 6 is wound on the stranded wheel 5; a mounting plate 7 is fixedly connected to the lower end of the steel wire rope 6; a motor 13 is installed on the mounting plate 7; a flexible shaft 14 is fixedly installed on the output end of the motor 13; a vibrator 15 is fixedly installed at the bottom of the flexible shaft 14. It should be noted that the main structure of the immersion vibrator is the motor 13, the flexible shaft 14, and the vibrator 15, which is existing technology and will not be described in detail here; a sealing plate 9 is fixedly installed at the bottom of the mounting plate 7; and a vibration damping mechanism is provided on the mounting plate 7.

[0024] In this method, the vibration damping mechanism includes a support groove 11 and a support tube 16. A sliding cover 12 is slidably installed on the support groove 11. Several springs 17 are fixedly connected between the inner sides of the support groove 11 and the sliding cover 12. The support tube 16 is screwed onto the mounting plate 7. A flexible shaft 14 passes through the support tube 16. A sponge tube sleeve 20 is sleeved between the inner wall of the support tube 16 and the flexible shaft 14. A concrete feeding pipe 10 is installed on the mounting plate 7 and extends to the bottom of the mounting plate 7.

[0025] With the above-described configuration, concrete material can be added to the inside of the sealing plate 9 at the bottom of the mounting plate 7 via the concrete feeding pipe 10.

[0026] In this configuration, the composite cavity shear wall 2 includes a first wall panel 21 and a second wall panel 22, with connecting steel bars 23 welded between the first wall panel 21 and the second wall panel 22.

[0027] With the above-described configuration, the connecting steel bar 23 connects the first wall panel 21 and the second wall panel 22. The connecting steel bar 23 serves as a connecting skeleton. By pouring concrete inside the connecting steel bar 23, the connecting steel bar 23 and the poured concrete together form the connecting rib between the first wall panel 21 and the second wall panel 22.

[0028] In this configuration, mounting bases 31 are fixedly connected to both sides of the top plate 3.

[0029] With the above-described configuration, the top plate 3 can be fixedly installed on the load-bearing main body of the structure via the mounting base 31, providing a fixed support for the top plate 3.

[0030] In this method, sliding rods 8 are symmetrically fixedly installed on the upper side of the mounting plate 7, and the upper end of the sliding rods 8 slides through to the upper side of the top plate 3.

[0031] By setting the slide bar 8 in the above manner, the mounting plate 7 slides vertically when moving up and down, and will not swing horizontally.

[0032] In this method, the installation position of the sealing plate 9 corresponds to the position of the connecting steel bar 23, and the distance between the inner side of the sealing plate 9 and the outer side of the connecting steel bar 23 meets the requirements of the protective layer thickness.

[0033] With the above-mentioned setup, the distance between the inner side of the sealing plate 9 and the outer side of the connecting steel bar 23 meets the requirements for the protective layer thickness. Therefore, after the concrete dries and solidifies, it meets the requirements for the protective layer thickness, providing protection for the inner connecting steel bar 23 and preventing the connecting steel bar 23 from being exposed and corroded.

[0034] In this configuration, a damper 18 is provided inside the spring 17, and a sealing ring 19 is provided at the threaded interface between the support tube 16 and the bottom of the mounting plate 7.

[0035] By setting up the sealing ring 19 as described above, concrete is prevented from entering the bottom screw interface between the support pipe 16 and the mounting plate 7 through the lower end of the support pipe 16 during the concrete pouring process, which would make it difficult to disassemble the support pipe 16 later.

[0036] The working principle of the concrete placing device for producing composite cavity shear walls provided by this utility model is as follows:

[0037] In use, the synchronous motor 4 is started to rotate and drive the stranded wheel 5 to lower the steel wire rope 6. The mounting plate 7 then gradually descends, driving it until it is in contact with the top of the composite cavity shear wall 2. The synchronous motor 4 then stops driving. At this point, the sealing plate 9 wraps around the connecting steel bar 23, forming a formwork effect for the connecting steel bar 23. Subsequently, concrete material is added to the inside of the sealing plate 9 through the concrete feeding pipe 10. At the same time, the motor 13 is started and drives the vibrator 15 through the flexible shaft 14 to vibrate the concrete material inside the sealing plate 9. After the concrete inside the sealing plate 9 is vibrated and compacted, the concrete is then dried and cured. After it has dried and formed, the synchronous motor 4 is started to drive the winch 5 to wind up the steel wire rope 6, which in turn drives the mounting plate 7 to rise. This causes the sealing plate 9 on the lower side of the mounting plate 7 to move upward synchronously, thus demolding the outer side of the connecting steel bar 23 inside the composite cavity shear wall 2. After demolding, the formed concrete wraps the inner connecting steel bar 23 inside, forming the connecting rib between the first wall panel 21 and the second wall panel 22.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
