Description

Technical Field

[0001] This invention relates to the field of post-pouring strip construction technology, specifically to a post-pouring strip construction device. Background Technology

[0002] Post-cast strip construction refers to the concrete strip left at corresponding positions in the foundation slab, wall, or beam during building construction to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement. According to design or construction specifications, this strip is poured after a certain period of time to allow for internal shrinkage of the component, thus connecting the structure into a whole. During the waiting period for the post-cast strip to be poured, it is necessary to prevent rainwater and debris from entering, avoid rusting of the reinforcing steel structure, and reduce the impact of impurities on strength.

[0003] CN219034113U discloses a protective component and construction device for post-pouring strips, including a cover plate and multiple reinforcing ribs. The cover plate is a semi-frame structure with an open bottom. Multiple reinforcing ribs are spaced apart inside the cover plate and closely attached to the top of the cover plate. The two ends of the reinforcing ribs are fixedly connected to the inner wall of the cover plate. The cover plate has multiple through mounting holes. The reinforcing ribs are provided to keep the installed post-pouring strip protective component in a stable state, making it less prone to deformation and playing a protective role.

[0004] CN216517014U discloses a construction device for protecting post-pouring strips. A reinforcing structure is provided at the top of the load-bearing plate and above the left concrete beam. A protective structure is provided at the top of the reinforcing structure to effectively protect the post-pouring strip. By setting the protective structure, the device can effectively protect the post-pouring strip in actual use, and at the same time, it can effectively prevent the surface of the post-pouring strip from being damaged due to the impact of falling heavy objects on the upper end of the post-pouring strip.

[0005] However, the above-mentioned devices for post-pouring strip construction still have the following problems in actual use: Although the post-pouring strip is protected by the construction device, such devices cannot block rainwater from the outside when they are working. When rainwater enters the post-pouring strip and comes into contact with the uncured concrete, it will cause the concrete to soften and lose strength, affecting the subsequent construction of the post-pouring strip. At the same time, the width of the post-pouring strip varies greatly depending on different construction needs, and the fixed construction device is difficult to adapt effectively, thus having significant drawbacks.

[0006] Therefore, we propose a post-pouring strip construction device to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a post-pouring strip construction device to solve the problems mentioned in the background art. Although current construction devices can protect post-pouring strips, they cannot block rainwater from entering the post-pouring strip. When rainwater enters the post-pouring strip and comes into contact with the uncured concrete, the concrete softens and loses strength, affecting the subsequent construction of the post-pouring strip. At the same time, the width of the post-pouring strip varies greatly depending on different construction requirements, and fixed construction devices are difficult to adapt effectively, resulting in significant drawbacks.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a post-pouring strip construction device, comprising a construction device body erected above the top surface of the post-pouring strip body, and telescopic water-resistant plates slidably arranged on both the left and right sides inside the construction device body.

[0009] A fall-prevention bearing plate is provided below the bottom surface of the post-cast strip body, and adjusting sleeves are fixedly installed on the left and right sides of the inside of the fall-prevention bearing plate in a symmetrical manner; it also includes:

[0010] The top surface of the construction device body is provided with a locking mechanism, which includes a locking frame and a drive shaft, and the locking frame is fixedly installed at the center of the top surface of the construction device body.

[0011] The symmetrically arranged telescopic water-blocking plates are equipped with water-blocking mechanisms at their outer ends. These mechanisms include anti-seepage sliding plates and water-blocking flip plates, with the anti-seepage sliding plates symmetrically sliding on the top surface of the construction device body.

[0012] Preferably, the width of the post-pouring strip body is greater than the width of the construction device body, and the transverse central axis of the construction device body and the transverse central axis of the post-pouring strip body are arranged parallel to each other, and a variable pitch mechanism is provided at the internal center position of the construction device body.

[0013] Preferably, the pitch-changing mechanism includes a drive gear and a drive rack, and the drive gear is rotatably mounted at the center of the construction device body via a bearing, and the drive racks are slidably mounted on the left and right sides of the construction device body, and the outer ends of the drive racks on the left and right sides are fixedly connected to the inner ends of the telescopic water-proof plate.

[0014] Preferably, the water-blocking mechanism includes guide teeth and guide gears, and the guide teeth are fixedly installed at equal intervals on the bottom surface of the left and right anti-seepage sliding plates, and the guide gears are fixedly installed on the inner ends of the left and right water-blocking flip plates, and the inner ends of the left and right water-blocking flip plates are rotatably set on the outer ends of the telescopic water-repellent plate.

[0015] Preferably, the water-blocking mechanism includes a water-blocking flip plate and a telescopic water-repellent plate connected to each other by a torsion spring, and the left and right water-blocking flip plates are connected to the guide tooth blocks on the bottom surface of the seepage-proof slide plate by the guide gears at their inner ends, and the seepage-proof slide plate is extended outward by the rotation of the water-blocking flip plate.

[0016] Preferably, the inner ends of the symmetrically arranged telescopic water-avoiding plates are provided with receiving guide grooves, and in the initial state, the telescopic water-avoiding plates are used to accommodate the drive rack through the receiving guide grooves. The spacing between the telescopic water-avoiding plates on the left and right sides and the water-blocking flip plate is adjusted according to the width of the post-pouring strip body.

[0017] Preferably, the water-blocking flip plates on the left and right sides abut against the top surface of the post-pouring strip body after flipping, and the water-blocking flip plates after flipping are arranged in an inclined structure with the outer end at the bottom and the inner end at the top. In the initial state, the water-blocking flip plates are horizontally housed inside the left and right sides of the construction device body through abutment, and the water-blocking flip plates and the telescopic water-avoiding plate in the initial state are horizontally coaxially distributed.

[0018] Preferably, the bottom surfaces of the symmetrically arranged telescopic water-proof plates are all fixedly connected to the top of the water collection and leak-proof plate, and the outer ends of the water collection and leak-proof plates on the left and right sides are attached to the inner wall of the post-pouring strip body after sliding. The water collection and leak-proof plates on the left and right sides support the construction device body on the top surface of the post-pouring strip body to prevent collapse.

[0019] Preferably, the locking mechanism includes an adjusting threaded rod and a transmission shaft. The adjusting threaded rod is symmetrically arranged inside the construction device body through bearings, and the transmission shaft is symmetrically arranged on the front and rear sides of the top of the construction device body through bearings. The bottom end of the symmetrically arranged adjusting threaded rod is threadedly connected to the adjusting sleeve inside the fall arrestor bearing plate.

[0020] Preferably, the outer ends of the symmetrically arranged transmission shafts are connected to the outer wall of the adjusting threaded rod through a first bevel gear, and the middle parts of the transmission shafts on the front and rear sides are connected to the outer ends of the drive shaft inside the locking frame through a second bevel gear. The installation height of the anti-fall bearing plate is adjusted by rotating the drive shaft and the transmission shaft.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This post-pouring strip construction device, through the construction device body in conjunction with the telescopic water-repellent plates and water-blocking flip plates on the left and right sides, blocks rainwater, improves the waterproof effect of the post-pouring strip body, and through the liftable anti-fall bearing plate attached to the post-pouring strip body, prevents the falling of debris and gravel inside the post-pouring strip body. The specific details are as follows:

[0022] 1. The construction device body is erected on the top surface of the post-pouring strip body by means of a water collection and leak-proof plate. Then, the rotating drive gear drives the drive rack and the telescopic water-proof plate to slide outward, so that the width of the construction device body and the telescopic water-proof plates on the left and right sides is greater than the width of the post-pouring strip body, so as to achieve efficient adaptation and improve the stability of construction protection.

[0023] 2. When the telescopic water-repellent plate inside the construction device body drives the water-blocking flip plate to slide outward synchronously, the water-blocking flip plate connected by the torsion spring is no longer obstructed by the construction device body, causing it to flip downward and abut against the top surface of the post-pouring strip body, while driving the anti-seepage slide plate to slide outward, so as to improve the water-blocking effect of the construction device body.

[0024] 3. The adjusting threaded rod inside the locking mechanism is threadedly connected to the adjusting sleeve inside the anti-fall bearing plate. The adjusting threaded rod drives the anti-fall bearing plate to adjust up and down, so that the top surface of the anti-fall bearing plate fits against the bottom surface of the post-pouring strip body, preventing debris and gravel from falling from inside the post-pouring strip body.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 The present invention provides the following technical solution:

[0038] Example 1: In order to solve the problem that the existing construction device body 2 cannot be adapted to the width of the post-pouring strip body 1, this example adopts the following technical solution: the construction device body 2 is mounted on the top surface of the post-pouring strip body 1 by means of a water collection and leak-proof plate 15, and then the rotating drive gear 10 drives the drive rack 11 and the telescopic water-proof plate 3 to slide outward, so that the width of the construction device body 2 and the telescopic water-proof plates 3 on the left and right sides is greater than the width of the post-pouring strip body 1, so as to achieve efficient adaptation and improve the stability of construction protection.

[0039] A construction device for post-pouring strips includes a construction device body 2 erected above the top surface of the post-pouring strip body 1, and telescopic water-resistant plates 3 are slidably arranged on both the left and right sides inside the construction device body 2; a pitch-changing mechanism is provided at the center of the construction device body 2; the pitch-changing mechanism includes a drive gear 10 and a drive rack 11, and the drive gear 10 is rotatably arranged at the center of the construction device body 2 through a bearing, and the drive racks 11 are slidably arranged on both the left and right sides inside the construction device body 2, and the outer ends of the drive racks 11 on both the left and right sides are fixedly connected to the inner ends of the telescopic water-resistant plates 3;

[0040] The inner ends of the symmetrically arranged telescopic water-avoiding plates 3 are provided with receiving guide grooves 14. In the initial state, the telescopic water-avoiding plates 3 are used to store the drive rack 11 through the receiving guide grooves 14. The distance between the telescopic water-avoiding plates 3 on the left and right sides and the water-blocking flip plate 9 is adjusted according to the width of the post-pouring strip body 1.

[0041] The bottom surfaces of the symmetrically arranged telescopic water-proof plates 3 are all fixedly connected to the top of the water collection and leak-proof plates 15, and the outer ends of the water collection and leak-proof plates 15 on both sides are attached to the inner wall of the post-pouring strip body 1 after sliding. The construction device body 2 is supported on the top surface of the post-pouring strip body 1 by the water collection and leak-proof plates 15 on both sides to prevent collapse.

[0042] like Figures 5-6 , Figure 10 As shown, when the construction device body 2 needs to be installed on the top surface of the post-pouring strip body 1, the drive gear 10 inside the construction device body 2 is manually rotated, causing it to drive the drive racks 11 connected to the left and right sides to slide outward. Then, the drive racks 11 drive the telescopic water-proof plates 3 at the outer end to slide outward. At the same time, the telescopic water-proof plates 3 on the left and right sides drive the water collection and leak-proof plates 15 at the bottom end to slide outward in sync. After the outer ends of the water collection and leak-proof plates 15 on the left and right sides abut against the inner wall of the post-pouring strip body 1, the width of the construction device body 2 and the telescopic water-proof plates 3 on the left and right sides is greater than the width of the post-pouring strip body 1, so as to achieve efficient adaptation and improve the stability of construction protection.

[0043] Example 2: In order to solve the problem that the existing construction device body 2 cannot block rainwater, this example adopts the following technical solution: when the telescopic water-repellent plate 3 inside the construction device body 2 drives the water-blocking flip plate 9 to slide outward synchronously, the water-blocking flip plate 9 connected by the torsion spring is no longer obstructed by the construction device body 2, so that it flips downward and abuts against the top surface of the post-pouring strip body 1, while driving the anti-seepage sliding plate 8 to slide outward, so as to improve the water-blocking effect of the construction device body 2.

[0044] The symmetrically arranged telescopic water-resistant plates 3 are equipped with water-blocking mechanisms at their outer ends. The water-blocking mechanisms include anti-seepage sliding plates 8 and water-blocking flip plates 9. The anti-seepage sliding plates 8 are symmetrically slidably arranged on the top surface of the construction device body 2. The width of the post-pouring strip body 1 is greater than the width of the construction device body 2. The transverse central axis of the construction device body 2 and the transverse central axis of the post-pouring strip body 1 are arranged parallel to each other. The water-blocking mechanism includes guide tooth blocks 12 and guide gears 13. The guide tooth blocks 12 are fixedly installed at equal intervals on the bottom surface of the left and right anti-seepage sliding plates 8. The guide gears 13 are fixedly installed on the inner ends of the left and right water-blocking flip plates 9. The inner ends of the left and right water-blocking flip plates 9 are rotatably arranged on the outer ends of the telescopic water-resistant plates 3.

[0045] The water-blocking mechanism includes a water-blocking flip plate 9 and a telescopic water-avoiding plate 3 connected to each other by a torsion spring. The water-blocking flip plates 9 on both sides are connected to the guide tooth block 12 on the bottom surface of the anti-seepage slide plate 8 by the guide gear 13 at the inner end. The rotation of the water-blocking flip plate 9 drives the anti-seepage slide plate 8 to extend outward. After flipping, the water-blocking flip plates 9 on both sides abut against the top surface of the post-pouring strip body 1. After flipping, the water-blocking flip plates 9 are arranged in an inclined structure with the outer end at the bottom and the inner end at the top. In the initial state, the water-blocking flip plates 9 are horizontally stored in the left and right sides of the construction device body 2. In the initial state, the water-blocking flip plates 9 and the telescopic water-avoiding plate 3 are horizontally coaxially distributed.

[0046] like Figure 5 , Figure 10 As shown, when the telescopic water-repellent plates 3 set on the left and right sides inside the construction device body 2 drive the water-blocking flip plates 9 to slide outward synchronously, the water-blocking flip plates 9, which were initially stored on the left and right sides inside the construction device body 2, are no longer resisted by the construction device body 2 when they slide outward. Then, the torsion spring connected to them drives the water-blocking flip plates 9 to flip downward, so that the bottom ends of the water-blocking flip plates 9 on both sides are in contact with the top surface of the post-pouring strip body 1, so that the inclined structure with the outer end at the bottom and the inner end at the top can effectively block the rainwater from the outside.

[0047] Furthermore, when the water-blocking flip plates 9 on both sides flip downwards simultaneously, the guide gear 13 set at its inner end meshes with the guide tooth block 12 on the bottom surface of the anti-seepage slide plate 8 during rotation, thereby driving the guide tooth block 12 and the anti-seepage slide plate 8 to slide outwards simultaneously. The sliding anti-seepage slide plate 8 covers the connection between the water-blocking flip plate 9 and the telescopic water-repellent plate 3, thereby covering the gap at the connection, improving the overall waterproof effect of the construction device body 2, and preventing external rainwater from contacting the concrete at the post-pouring strip body 1 and affecting its structural strength.

[0048] Example 3: In order to solve the problem that the existing construction device body 2 cannot solve the problem of debris and concrete blocks falling, this example adopts the following technical solution: the adjusting threaded rod 16 inside the locking mechanism is threadedly connected to the adjusting sleeve 5 inside the anti-fall bearing plate 4, and the adjusting threaded rod 16 drives the anti-fall bearing plate 4 to adjust in the up and down direction, so that the top surface of the anti-fall bearing plate 4 and the bottom surface of the post-pouring strip body 1 fit together, thus preventing debris and gravel from falling inside the post-pouring strip body 1.

[0049] A fall-prevention bearing plate 4 is provided below the bottom surface of the post-pouring strip body 1, and an adjusting sleeve 5 is fixedly provided on the left and right sides of the interior of the fall-prevention bearing plate 4 in a symmetrical manner. A locking mechanism is provided on the top surface of the construction device body 2. The locking mechanism includes a locking frame 6 and a drive shaft 7. The locking frame 6 is fixedly installed at the center of the top surface of the construction device body 2. The locking mechanism includes an adjusting threaded rod 16 and a transmission shaft 17. The adjusting threaded rod 16 is symmetrically arranged inside the construction device body 2 through bearings, and the transmission shaft 17 is symmetrically arranged on the front and rear sides of the top surface of the construction device body 2 through bearings. The bottom end of the symmetrically arranged adjusting threaded rod 16 is threadedly connected to the adjusting sleeve 5 inside the fall-prevention bearing plate 4.

[0050] The outer ends of the symmetrically arranged transmission shafts 17 are connected to the outer wall of the adjusting threaded rod 16 by the first bevel gear 18, and the middle parts of the transmission shafts 17 on the front and rear sides are connected to the outer ends of the drive shaft 7 inside the locking frame 6 by the second bevel gear 19. The installation height of the anti-fall bearing plate 4 is adjusted by the rotation of the drive shaft 7 and the transmission shaft 17.

[0051] like Figure 2 , Figures 7-8 As shown, when it is necessary to install the anti-fall bearing plate 4 and the construction device body 2 together, the anti-fall bearing plate 4 is first placed on the bottom surface of the post-pouring strip body 1, so that the adjusting sleeve 5 and the adjusting threaded rod 16 inside the locking mechanism correspond to each other. Then, the drive shaft 7 inside the locking mechanism is manually rotated, so that it drives the transmission shaft 17 on the front and rear sides of the top surface of the construction device body 2 to rotate through the second bevel gear 19 on the front and rear sides. The transmission shaft 17 drives the meshing adjusting threaded rod 16 to rotate synchronously through the first bevel gear 18 at the outer end, so that the adjusting sleeve 5 and the anti-fall bearing plate 4, which are threadedly connected to the adjusting threaded rod 16, slide upward, and the top surface of the anti-fall bearing plate 4 and the bottom surface of the post-pouring strip body 1 are in contact with each other, so as to prevent the falling of debris and gravel inside the post-pouring strip body 1.
