Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and particularly relates to a delayed demoulding support system for an aluminum mold material transfer port. 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 a special transport elevator or tower crane on the outer wall, saving construction costs and improving construction progress.

[0003] Typically, when pouring structural panels at the aluminum formwork feed port, the sides of the opening in the building's structural panels must be chiseled out, rebar removed, and cleaned to facilitate installation. Re-casting requires re-rebar and a secondary wooden formwork top support for layered pouring, which is cumbersome and costly. Furthermore, when the feed port is not in use, workers are prone to falling accidents, reducing safety.

[0004] In order to solve this problem, the existing patent application number is "202123430151.5" and the name is "A 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 and second protective plates are set to block the transfer port to prevent workers from stepping on air and falling, thereby improving the safety of the device.

[0005] However, the prior art still has the following problems:

[0006] 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, and load unloading may occur at the joints, especially at the joints of the material transfer port, due to unloading and the return of the secondary structure. This may lead to quality problems some time after the concrete is poured. Utility Model Content

[0007] The purpose of this utility model is to provide a delayed demolding support system for aluminum mold transfer ports, effectively avoiding the quality issues associated with secondary return (unloading) pouring of the transfer ports. This improves the construction quality of the transfer ports, while also accelerating construction progress, reducing maintenance, and lowering construction costs.

[0008] In order to achieve the above technical effects, the technical solutions adopted by the present invention are as follows:

[0009] A delayed demoulding support system for an aluminum mold material transfer port includes a floor template system. A rectangular reserved opening is reserved in the middle of the floor template system. A sliding template is detachably installed in the middle of the reserved opening. Steel support templates are arranged on both sides of the sliding template.

[0010] Preferably, the floor formwork system is welded together by four long formworks, two short formworks and a bottom plate, and a reinforcing rib is provided between the two long formworks.

[0011] Preferably, the sliding template is a groove-shaped template bin, and both ends of the inner cavity are integrally formed widened bodies, and positioning holes are provided on the widened bodies.

[0012] Preferably, the steel support formwork is welded by four equal-length support rod modules and a base plate. The inner top surface of the base plate is provided with a mounting tube, and a horizontal plate is fixedly provided on the side wall of the mounting tube. Screw holes are opened on the horizontal plate, and a screw rod passes through the screw hole and is rotated to be set in the positioning hole.

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

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This new aluminum mold transfer port delayed removal system effectively avoids quality issues associated with secondary return (unloading) pouring of the transfer port. This improves transfer port construction quality, speeds up construction progress, reduces maintenance, and lowers construction costs.

[0016] 2. The present invention is provided with a sliding template, which can be used as a blanking template by cooperating with a screw rod, reducing the process of installing multiple templates at the blanking port. Moreover, due to the different pouring thicknesses of different building floor slabs, 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, greatly saving the construction process and improving the construction accuracy. On the other hand, through adjustment, the sliding template can be used as a template for the final reserved opening pouring, realizing multiple functional uses of a template and improving construction efficiency.

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention. Example

[0026] Refer to the attached Figure 1-5 A delayed demolding support system for an aluminum mold material transfer port includes a floor formwork system 1. A rectangular reserved opening 103 is reserved in the middle of the floor formwork system 1. A sliding formwork 3 is detachably installed in the reserved opening 103, and steel support formwork 2 is detachably installed on both sides by bolts.

[0027] In addition, the steel support formwork 2 can also be directly welded to the floor formwork system 1 to form an integrated structure.

[0028] 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 provided between the two long formworks 101 .

[0029] 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.

[0030] Furthermore, the thickness of all templates is 4 mm.

[0031] The sliding template 3 is a groove-shaped template bin, and both ends of the inner cavity are integrally formed widened bodies 301 , and positioning holes 302 with smooth inner walls are opened on the widened bodies 301 .

[0032] The steel support formwork 2 is welded together from four equal-length support rod modules and a base plate 105. The inner side of the base plate 105 is provided with a mounting tube 201, into which is inserted an adjustable, independent Ø60 steel support with a wall thickness of 2.5 mm. The sidewalls of the mounting tube 201 are integrally formed with a horizontal plate 202, which is positioned opposite each other. Each of the horizontal plates 202 has screw holes through which the screw rod 4 passes and is then rotated into the positioning hole 302.

[0033] During use, the screw rod 4 is passed through the screw hole and pressed against the widened body 301 , and the screw rod 4 is rotated to move the sliding template 3 upward, thereby realizing position adjustment of the sliding template 3 .

[0034] Furthermore, the size of the steel support formwork 2 is 200X200mm and 4mm thick;

[0035] In one method, the side walls of the floor formwork system 1 and the steel support formwork 2 are each provided with pin holes 5 spaced 150 mm apart. Pins (φ16×65) and pin plates (3.5×70) are inserted into the pin holes 5 for connection, with the spacing between the pins (φ16×65) and pin plates (3.5×70) being 100–150 mm.

[0036] In another way, the side walls of the floor formwork system 1 and the steel support formwork 2 are directly welded to make the floor formwork system 1 and the steel support formwork 2 into an integrated structure, which is more convenient to install and use.

[0037] The construction method of this embodiment is:

[0038] Step 1: Connect the floor formwork system 1 to the floor slab casting formwork through pins;

[0039] Step 2: Connect the steel support formwork 2 to the floor formwork system 1 through pins, insert the sliding formwork 3 into the middle reserved opening 103 of the floor formwork system 1, tighten the screw rod 4 into the screw hole, and lift the sliding formwork 3 upward. According to the needs of construction, lift the sliding formwork 3 to be equal to or higher than the casting surface;

[0040] Step 3: After the pouring solidifies, rotate the screw 4 downward to remove the sliding formwork 3; in the final pouring stage of the material transfer port, reinstall and jack up the sliding formwork 3, with the upper end surface flush with the floor formwork system 1. After pouring and solidification, remove the formwork after curing is completed.

[0041] This novel device and method effectively improves the construction quality of the feed opening, reducing issues such as unloading of the opening structure, grout leakage, and poor concrete appearance caused by the secondary formwork backing process. It also avoids secondary polishing and repair after formwork removal, effectively controlling quality issues such as cracking and leakage at the feed opening. Furthermore, the feed opening does not require secondary formwork during pouring, accelerating construction progress and reducing costs. Furthermore, during construction of the feed opening structure, the surrounding structural panels are unloaded.
