Description

Technical Field

[0001] The invention belongs to the technical field of construction, and in particular relates to an adjustable aluminum mold material transfer port delayed mold removal support system and a construction method thereof. Background Art

[0002] In the field of construction, especially in the field of building construction, in order to facilitate the transportation of materials between floors, material transfer ports are often opened at specific locations. The material transfer ports are in the same position in the vertical direction. The setting of the material transfer ports avoids the need to set up special transport elevators or tower cranes on the outer wall, saving construction costs and improving construction progress.

[0003] Usually, when pouring the structural plate at the aluminum mold feed port, in order to facilitate the installation of the aluminum mold feed port template, the side of the structural plate hole in the building needs to be chiseled off, the steel bars removed, and cleaned. When pouring again, the steel bars need to be replanted, and the wooden template needs to be used for secondary top support for layered pouring, which is troublesome and costly. At the same time, when the feed port is not in use, workers are prone to falling accidents, and the safety factor is low.

[0004] In order to solve this problem, the existing patent application number is "202123430151.5" and the name is "A patent for an aluminum mold transfer port template". By setting a notch at the bottom of the iron box, the template can meet the use of reserved steel bars, making construction more convenient. At the same time, when the transfer port is not in use, the first protective plate and the second protective plate are set to block the transfer port to prevent the staff from stepping on air and falling, thereby improving the safety of the device.

[0005] However, the prior art still has the following problems: During the subsequent closure construction of the material transfer port, the formwork needs to be removed and re-supported. After all the supporting structures of the material transfer port are removed, quality problems such as cracks, leakage, load unloading, etc. may occur at the joints, especially at the connection points of the material transfer port, due to unloading and the return of the secondary structure, some time after the concrete pouring is completed. Summary of the invention

[0006] The purpose of the present invention is to provide an adjustable aluminum mold material transfer port delayed demoulding support system and a construction method thereof, which can effectively avoid the quality problems caused by the secondary return (unloading) pouring method of the material transfer port, improve the construction quality of the material transfer port, speed up the construction progress, reduce maintenance, and reduce construction costs.

[0012] Preferably, a square hole and a round hole are opened in the mounting tube, and the support rod assembly includes an inner support rod and an outer rotating rod. The top of the inner support rod is a square rod that cooperates with the square hole, and the lower part is a cylindrical rod. The outer rotating rod is sleeved outside the inner support rod, and the upper part of the outer rotating rod is a square rod that cooperates with the square hole of the driving gear. The lower part of the outer rotating rod is a cylindrical rod, and the cylindrical rod is inserted into the cylindrical rod.

[0013] Preferably, the side walls of the floor formwork system and the steel support formwork are provided with pin holes.

[0014] A construction method of an adjustable aluminum mold material transfer port delayed mold removal support system, comprising: Step 1: Connect the floor formwork system to the floor slab casting formwork through pins; Step 2: Connect the steel support formwork to the floor formwork system through pins; insert the support rod assembly into the installation cylinder, insert the square rod of the inner support rod into the square hole to match, so as to achieve positioning and prevent rotation; the square rod of the outer rotating rod matches the square hole of the driving gear to drive the driving gear, and the cylindrical rod is inserted into the cylindrical rod; Step 3: Insert the sliding template into the reserved opening in the middle of the floor template system, and rotate the top of the screw rod to connect with the positioning hole; Step 4: The inner support rod supports the floor formwork system. Hold the handle and rotate the outer rotating rod. The square rod at the upper end of the outer rotating rod will drive the driving gear to rotate, the driving gear drives the intermediate gear to rotate, and the intermediate gear drives the driven gear to rotate, which will drive the screw rod downward or upward, thereby moving the sliding formwork upward or downward to adjust the position of the sliding formwork.

It improves the construction quality of the material transfer port, speeds up the construction progress, reduces maintenance, and reduces construction costs.

[0016] 2. The present invention is provided with a sliding template, which can be used as a feed port template by cooperating with a screw rod, thereby reducing the process of installing multiple templates at the feed port. Moreover, due to the different pouring thicknesses of different building floors, in order to avoid the poured concrete covering the template, the template is often higher than the pouring surface. The protruding template will affect the construction of the thick floor surface. The sliding template of the present invention can be adjusted to different heights as needed to achieve flushness with the pouring surface, which greatly saves construction processes and improves construction accuracy. On the other hand, through adjustment, the sliding template can be used as a template for pouring the final reserved port, thereby realizing multiple functional uses of one template and improving construction efficiency.

[0017] 3. The existing conventional formwork support and adjustment all require ladders or scaffolding, and then workers operate on top. This operation process is cumbersome, requires more manpower, and there are certain safety hazards in climbing. The present invention is provided with a gear assembly and a support rod assembly. Workers can stand on the bottom surface and rotate the support rod assembly to adjust the gear assembly, and further adjust the height of the sliding formwork. This operation method is simple, safe, convenient and fast, which greatly improves the efficiency of construction.

[0018] In addition, when the sliding formwork needs to be removed, the support rod can be connected to the sliding formwork, so that the sliding formwork can be removed conveniently and quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In addition, the steel support formwork 2 can also be directly welded to the floor formwork system 1 to form an integrated structure.

[0025] The floor formwork system 1 is welded together by four long formworks 101 , two short formworks 102 and a bottom plate 105 , and a reinforcing rib 104 is arranged between the two long formworks 101 .

[0026] Furthermore, the length of the long template 101 is 1200 mm, the length of the short template 102 is 600 mm, and the length of the reserved opening 103 is 800 mm and the width is 200 mm.

[0027] Furthermore, the thickness of all templates is 4 mm.

[0028] The sliding template 3 is a groove-shaped template bin, and the two ends of the inner cavity are integrally formed widened bodies 301 , and the widened body 301 is provided with positioning holes 302 with smooth inner walls.

[0029] The steel support template 2 is welded by four equal-length support rod modules and a bottom plate 105. The inner side of the bottom plate 105 is provided with a mounting tube 201. A Φ60 adjustable independent steel support with a wall thickness of 2.5 mm is inserted into the mounting tube 201.

The horizontal plate 202 is provided with a screw hole. After the screw rod 4 passes through the screw hole, it is rotated and set in the positioning hole 302. When in use, the screw rod 4 is passed through the screw hole and then supported against the widened body 301. The screw rod 4 is rotated to move the sliding template 3 upward, thereby realizing the position adjustment of the sliding template 3.

[0030] Further, the size of the steel support formwork 2 is 200X200mm and 4mm thick; In one method, the side walls of the floor formwork system 1 and the steel support formwork 2 are both provided with pin holes 4, and the interval between the pin holes 4 is 150 mm.

This is more conducive to the support stability of the sliding formwork 3.

[0040] The threaded connection is provided because when the sliding formwork 3 is removed, the connection of the threaded rod is firm and can be laid down by one construction worker, thus solving the problem that implementation 1 requires manual labor to climb up a ladder to take it.

[0041] In addition, the lower parts of the support rod 11 and the inner support rod 8 are both adjustable independent steel supports, that is, the height can be adjusted. This structure is an existing structure and will not be repeated here.
