Abstract
Description
Technical Field
[0001] This invention relates to the field of building construction technology, and in particular to a sealing device for material conveying openings in building floor slabs. Background Technology
[0002] During construction, in order to facilitate the timely transfer of aluminum formwork and supporting facilities to the next floor, a material transfer port is opened on the floor slab as a transfer channel. After the material transfer port is used, it needs to be sealed.
[0003] The current sealing device used for sealing the material conveying port includes a sealing plate of a size that matches the material conveying port, and a support structure under the sealing plate. The support structure is erected using wooden beams and steel pipe support frames to support the sealing plate, but it has the following problems.
[0004] First, due to changes in building height or mismatched dimensions of timber and steel pipes, the formwork may not be able to seal the openings tightly, resulting in grout leakage and potential water seepage in the floor slab later.
[0005] In addition, the traditional timber and steel pipe support frame erection process is cumbersome and time-consuming to dismantle and assemble. Furthermore, different floor heights require on-site cutting of timber or readjustment of steel pipe lengths, resulting in significant material waste and low turnover efficiency, which seriously restricts the construction progress and increases labor costs.
[0006] Therefore, the present invention proposes a sealing device for the material transfer port of a building floor slab. Summary of the Invention
[0007] The purpose of this invention is to provide a sealing device for material conveying openings in building floor slabs to solve the problems mentioned in the background art. This device is height-adjustable, easy to assemble and disassemble, provides stable support, effectively prevents grout leakage, and is flexible in turnover, significantly improving construction efficiency and sealing quality.
[0008] The technical solution of the present invention is: a sealing device for material conveying openings of building floor slabs, comprising a pair of uprights, each pair of uprights having a support rod slidably installed inside, an aluminum template being provided at the top of the pair of support rods, a support plate being fixedly installed at the bottom of each upright, a pair of fixing rods being fixedly installed at the bottom of the aluminum template, the fixing rods being slidably installed on the inner top of the support rods, and further comprising a diagonal bracing assembly and a fixing assembly.
[0009] A diagonal brace assembly, which is mounted on a support rod.
[0010] The diagonal bracing assembly includes a fixed seat that is fixedly mounted on a support rod by a fixing pin, a diagonal bracing rod that is hinged to the fixed seat, and a diagonal bracing cylinder that is threadedly connected to the diagonal bracing rod.
[0011] A fixing component is mounted on the upright.
[0012] The fixing component includes a threaded portion at the end of the pole, and a pair of threaded cylinders are threadedly connected to the threaded portion. A positioning cylinder is rotatably mounted between the pair of threaded cylinders.
[0013] In some embodiments, the bottom of the inclined support cylinder is hinged with an anti-slip plate, and the bottom of the anti-slip plate is provided with rubber anti-slip texture.
[0014] In some embodiments, the support rod has multiple pin holes at equal intervals, the upright has a strip hole near the threaded part, the positioning cylinder and the support rod are connected together by a positioning pin, and a connecting rod is fixedly connected between a pair of threaded cylinders.
[0015] In some embodiments, the positioning pin passes through the strip hole, and the positioning cylinder has a through hole adapted to the positioning pin.
[0016] In some embodiments, a pair of mounting seats are fixedly installed on both the upright and the support rod, and a crossbar is fixedly connected between the pair of mounting seats. The mounting seats are fixedly provided with insertion holes, and a pair of insertion rods are fixedly installed on the crossbar. The insertion rods are slidably inserted into the insertion holes.
[0017] This invention provides an improved material conveying port sealing device for building floor slabs, which has the following improvements and advantages compared with the prior art:
[0018] Firstly, this invention achieves precise adaptation to changes in floor height through a dual adjustment mechanism combining coarse and fine adjustments. The equally spaced pin holes on the support rod, in conjunction with the positioning pins, enable rapid coarse positioning; while the precision helical transmission structure, composed of the threaded section, threaded cylinder, and positioning cylinder, allows for stepless fine adjustment of the support height. This design effectively avoids the defects of traditional construction methods, such as insufficient support and inability of the sealing plate to press firmly against the floor slab due to fixed timber lengths or limited steel pipe dimensions. It ensures a seamless fit between the sealing plate and the bottom surface of the floor slab at the material transfer port, eliminating the risk of grout leakage at its source, and significantly improving the construction turnover efficiency between different floors.
[0019] Secondly, this invention adopts a plug-in split design, which can be disassembled into two sections, effectively reducing the length of individual components and facilitating vertical transportation between floors and handling in confined spaces. Simultaneously, the crossbars are plugged into the mounting brackets on the uprights via end inserts, and the diagonal bracing components achieve quick retraction through hinges and threaded sleeves. The entire system eliminates the cumbersome operations of traditional fastener tightening and timber nailing, allowing for assembly and disassembly without the need for complex tools, significantly shortening the time required for sealing material conveyor openings on each floor and reducing labor costs.

[0028] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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.
[0029] This invention provides an improved material conveying port sealing device for building floor slabs. The technical solution of this invention is as follows:
[0030] like Figures 1 to 5As shown, this embodiment of the invention provides a sealing device for a material transfer port in a building floor slab, including a pair of uprights 1. Support rods 2 are slidably installed inside each pair of uprights 1. An aluminum template 3 is provided at the top of each pair of support rods 2. A support plate 9 is fixedly installed at the bottom of each upright 1. A pair of fixing rods 4 are fixedly installed at the bottom of the aluminum template 3. The fixing rods 4 are slidably installed on the inner top of the support rods 2. The device also includes a diagonal bracing assembly and a fixing assembly. The uprights 1, as the main vertical load-bearing components, are made of round steel pipes. The support rods 2 are slidably fitted inside the uprights 1, with a clearance fit between them to ensure smooth lifting and lowering. The aluminum template 3 is used to support the sealing plate and transfer the load from the upper concrete pouring. The flatness of its top surface directly affects the sealing compaction effect. The support plate 9 is a round or square steel plate welded to the bottom of the upright 1. Its diameter is larger than the outer diameter of the upright 1, which can effectively disperse the pressure at the bottom of the upright 1, preventing concentrated construction loads from causing damage to the floor slab structure or uneven settlement of the device.
[0031] The diagonal brace assembly is mounted on the support rod 2.
[0032] The diagonal bracing assembly includes a fixed seat 5 that is fixedly mounted on the support rod 2 by a fixing pin. A diagonal bracing rod 6 is hinged to the fixed seat 5, and a diagonal bracing cylinder 7 is threadedly connected to the diagonal bracing rod 6. The fixed seat 5 and the support rod 2 are rigidly connected by the fixing pin to ensure the effective transmission of the diagonal bracing force. The diagonal bracing rod 6 and the fixed seat 5 are hinged, allowing it to swing freely within a certain angle range around the hinge point, which facilitates the construction personnel to flexibly adjust the tilt angle of the diagonal bracing according to the position of the support surface on site. The diagonal bracing cylinder 7 is sleeved on the end of the diagonal bracing rod 6 and threadedly engaged with it. By rotating the diagonal bracing cylinder 7, the total length of the diagonal bracing assembly can be changed, thereby achieving precise application and release of the diagonal bracing force, which is simple and labor-saving to operate.
[0033] The fixing component is installed on the upright 1.
[0034] The fixing assembly includes a threaded portion 17 at the end of the upright 1. A pair of threaded cylinders 14 are threadedly connected to the threaded portion 17. A positioning cylinder 15 is rotatably mounted between the pair of threaded cylinders 14. The threaded portion 17 is an external thread section machined on the outer wall of the upper end of the upright 1. The pair of threaded cylinders 14 are screwed onto the threaded portion 17, and the two threaded cylinders 14 are fixed together by a connecting rod 16 to achieve synchronous rotation. The positioning cylinder 15 is sleeved on the outside of the support rod 2, and its two ends are rotatably engaged with the inner end faces of the two threaded cylinders 14, so that when the threaded cylinders 14 rotate, they will not drive the positioning cylinder 15 to rotate together. Instead, the helical motion is converted into linear movement of the positioning cylinder 15 along the axial direction of the upright 1.
[0035] Furthermore, the bottom of the diagonal brace cylinder 7 is hinged with an anti-slip plate 8. The bottom of the anti-slip plate 8 is provided with rubber anti-slip texture. When the diagonal brace cylinder 7 is rotated, the effective support length of the diagonal brace rod 6 can be changed, so that the anti-slip plate 8 can be tightly abutted against the floor or beam side structural surface. The rubber anti-slip texture generates a large frictional resistance after being compressed, which effectively prevents the diagonal brace component from slipping or loosening during the concrete pouring and vibration process, ensuring the reliability of the top support. At the same time, the hinged structure allows the anti-slip plate 8 to automatically adapt to support surfaces of different angles, improving the fault tolerance of on-site installation.
[0036] Furthermore, multiple pin holes 20 are evenly spaced on the support rod 2, and a strip hole 18 is opened on the upright 1 near the threaded part 17. A positioning pin 19 is inserted between the positioning cylinder 15 and the support rod 2. A connecting rod 16 is fixedly connected between a pair of threaded cylinders 14. The strip hole 18 provides vertical guide stroke for the positioning pin 19, avoiding movement interference between the upright 1 tube wall and the pin. The connecting rod 16 is fixedly connected between the two threaded cylinders 14. Construction personnel can hold the connecting rod 16 with both hands at the same time to apply force, so that the two threaded cylinders 14 rotate synchronously on the threaded part 17, thereby pushing the positioning cylinder 15 to move smoothly. This facilitates precise adjustment of the position of the positioning pin 19 inside the strip hole 18, thereby ensuring that the positioning pin 19 can be accurately positioned with the pin hole 20. Compared with directly opening holes on the upright 1, this method can better and more accurately adjust the adjustment distance of the support rod 2, thus better adapting to the spacing between floor slabs.
[0037] Furthermore, the positioning pin 19 passes through the strip hole 18, and the positioning cylinder 15 has a through hole that matches the positioning pin 19. During installation, the positioning pin 19 is passed through the strip hole 18 on the upright 1, the through hole on the positioning cylinder 15, and the corresponding pin hole 20 on the support rod 2 in sequence to achieve a concentric connection of the three holes, thereby firmly locking the support rod 2 inside the upright 1. This effectively prevents the support rod 2 from sliding down or moving axially when bearing the vertical load of the upper sealing plate and the cast-in-place concrete, ensuring the high stability of the support system throughout the entire pouring process.
[0038] Furthermore, a pair of mounting seats 10 are fixedly installed on both the upright 1 and the support rod 2. A crossbar 11 is fixedly connected between the pair of mounting seats 10. The mounting seats 10 are fixedly provided with insertion holes 12. A pair of insertion rods 13 are fixedly installed on the crossbar 11. The insertion rods 13 are slidably inserted into the insertion holes 12. The insertion rods 13 and the insertion holes 12 adopt a plug-in clearance fit, which can realize the quick installation and disassembly of the crossbar 11 without the need for additional tools. In practical applications, multiple sets of mounting seats 10 can be set at different height positions of the upright 1 and the support rod 2 according to the support height requirements, and one or more crossbars 11 can be installed accordingly to enhance the lateral connection stiffness between the two uprights 1, form a stable portal frame system, effectively constrain the relative lateral displacement of the two uprights 1, and resist the lateral disturbance caused by personnel movement and concrete pouring during the construction process.
[0039] The specific working principle is as follows: First, place a pair of uprights 1 according to the position of the material transfer port of the floor slab, insert the support rod 2 into the uprights 1 accordingly, select the appropriate height of the pin hole 20 according to the floor clear height, and initially insert the positioning pin 19 to complete the coarse adjustment; then rotate the connecting rod 16 to drive the two threaded cylinders 14 to rotate synchronously, and through the precision screw transmission of the threaded part 17, make the positioning cylinder 15 move slightly along the axis of the upright 1, so that the through hole on the positioning cylinder 15 is aligned with the pin hole 20 shown in the strip hole 18, so as to facilitate the use of the positioning pin 19 for fixing; then install the crossbar 11, insert the insert rods 13 at both ends of the crossbar 11 into the insertion holes 12 of the mounting bases 10 on both sides respectively, and connect the two uprights 1; finally install the diagonal bracing assembly, fix the fixing base 5 to the support rod 2 with the fixing pin, rotate the diagonal bracing cylinder 7 so that the anti-slip plate 8 tightly supports the floor or beam side structure surface, forming a stable back-top support system. After all the supports are completed, concrete is poured into the material inlet and cured to the design strength. Then, the operation is reversed, and the diagonal bracing components and crossbar 11 are removed in sequence. The positioning pin 19 is pulled out, and the upright 1 and support rod 2 are separated. The entire set of equipment can then be quickly transferred to the next construction section for reuse, which effectively improves the construction efficiency of sealing the material inlet, while ensuring the sealing tightness and avoiding the risk of leakage in the later stage.
