Description

Technical Field

[0001] This application relates to the field of confined space casting technology, and in particular to an aluminum profile module for indoor confined space casting. Background Technology

[0002] Aluminum formwork, also known as aluminum alloy formwork system for construction, is a new generation of formwork support system that emerged after bamboo and wood formwork and steel formwork. The application of aluminum formwork systems in the construction industry has improved the overall construction efficiency, significantly saving on building materials and labor. Aluminum formwork is a building formwork made of aluminum alloy, also known as aluminum alloy formwork. It refers to a modular design, where aluminum formwork is extruded using specialized equipment. It consists of three parts: aluminum panels, supports, and connectors, and has a complete set of universal accessories for use. It can be assembled into complex overall formwork of different sizes, enabling prefabricated and industrialized construction. This system solves the shortcomings of traditional formwork and greatly improves construction efficiency.

[0003] However, when casting in confined indoor spaces, such as electrical shafts or weak current shafts, the limited space makes it difficult for workers to install diagonal braces for reinforcement after the inner aluminum formwork is assembled and the back bracing is installed. This causes the aluminum formwork to deform during subsequent casting, severely affecting the casting result. Therefore, further improvements are needed. Summary of the Invention

[0004] In order to support and reinforce the sides and front of the inner aluminum formwork in a confined space, this application provides an aluminum profile template for casting in a confined indoor space.

[0005] This application provides an aluminum profile template for indoor confined space casting, which adopts the following technical solution:

[0006] An aluminum profile template for indoor confined space casting includes an outer aluminum template, an inner aluminum template, an outer support member, and an inner support member. The outer aluminum template is arranged and spliced ​​along the outer boundary of the area to be cast, and the inner aluminum template is arranged and spliced ​​along the inner boundary of the area to be cast, to form a casting space. Back ribs are installed in layers on both the outer and inner aluminum templates. The outer support member is a diagonal brace and is laid at intervals along the outer aluminum template. The outer support member supports and fixes the outer aluminum template by supporting the back ribs on the outer aluminum template. The inner support member is installed on the inner side and is arranged at intervals along the vertical direction. The inner support member is horizontally arranged and is used to simultaneously support and reinforce the two sides and the front of the inner aluminum template.

[0007] By adopting the above technical solution, in actual operation, the outer support is a diagonal brace, which directly supports and fixes the outer aluminum template by supporting the back ribs on the outer aluminum template. In addition, the inner support is a horizontal support, which can adapt to the limited internal space and provide support and reinforcement to the sides and front of the inner aluminum template.

[0008] Optionally, the inner support includes a bidirectional adjusting rod, side pressure plates installed at both ends of the bidirectional adjusting rod, and a positive pressure plate installed between the two side pressure plates. The length of the positive pressure plate is adjustable, and the two side pressure plates are used to support and reinforce the two sides of the inner aluminum template, while the positive pressure plate is used to support and reinforce the front of the inner aluminum template.

[0009] By adopting the above technical solution, in actual use, two side pressure plates are used to support and reinforce both sides of the inner aluminum template, and a positive pressure plate is used to support and reinforce the front of the inner aluminum template.

[0010] Optionally, the bidirectional adjusting rod includes an adjusting cylinder and threaded rods threaded to both ends of the adjusting cylinder. The threads at both ends of the adjusting cylinder rotate in opposite directions, and a U-shaped handle is provided in the middle of the adjusting cylinder for worker adjustment.

[0011] Optionally, the side pressure plate is used to connect a first slide rail that extends along its length on one side, and limit blocks are provided at both ends of the first slide rail; two first sliders are slidably arranged on the first slide rail, and two connecting rods are hinged to the end of the threaded rod away from the adjusting cylinder, and the two connecting rods are respectively hinged to the two first sliders on the side pressure plate on the corresponding side.

[0012] By adopting the above technical solution, during use, two side pressure plates are respectively installed and connected to the back ribs on both sides of the inner aluminum template. The worker holds the U-shaped handle with both hands to rotate and adjust the adjusting cylinder. The rotation of the adjusting cylinder drives the two threaded rods to move away from each other, so that the two connecting rods on each side drive the two first sliders to move away from each other until the side pressure plates are pressed tightly, thereby supporting and fixing the two sides of the inner aluminum template.

[0013] Optionally, each end of the side pressure plate is provided with a first connecting seat, and each of the back ribs on both sides is provided with two second connecting seats. The first connecting seats and the second connecting seats are connected and fixed by bolts and nuts.

[0014] By adopting the above technical solution, during the installation process, the two side pressure plates are supported on the back ribs on both sides respectively, and the two first connecting seats on the side pressure plates are aligned with the two second connecting seats on the same side. Then, they are connected and fixed by bolts and nuts, so that the side pressure plates can be removed and fixedly installed on the back ribs of the inner aluminum template.

[0015] Optionally, the positive pressure plate includes a left pressure plate, a right pressure plate, and a guide slide rod installed between the left pressure plate and the right pressure plate; one end of the guide slide rod is fixed to the base pressure plate, and the other end is slidably inserted into the right pressure plate; both the left pressure plate and the right pressure plate are provided with guide push rods on their back sides, and the guide push rods on both sides are slidably inserted through the limiting block on the corresponding side and extend into the first slide rail.

[0016] By adopting the above technical solution, in practical application, on the one hand, when the side pressure plate needs to be installed on the back rib on the corresponding side, the positive pressure plate will be lengthened or shortened accordingly as the distance between the two side pressure plates is adjusted. On the other hand, when the inner support is fixed and adjusted by rotating the adjusting cylinder, the two connecting rods on the threaded rod control the two first sliders to move away from each other. At this time, the first slider pushes the guide push rod outward to push the left and right pressure plates in the positive pressure plate to press against the front part of the inner aluminum template to support and reinforce it.

[0017] Optionally, a telescopic guide rod is installed between the two side pressure plates, with both ends of the telescopic guide rod fixedly connected to the two side pressure plates respectively.

[0018] By adopting the above technical solution, in actual use, by setting a telescopic guide rod, it is possible to provide auxiliary guidance for the relative or opposite movement of the two side pressure plates, so as to further improve the stability of their movement.

[0019] Optionally, the top of both the left and right pressure plates is provided with a second slide rail extending along its length. A second slider is slidably mounted on the second slide rail, and an elastic abutment block is fixedly installed on the second slider. The elastic abutment block is used to abut against the inner aluminum template.

[0020] By adopting the above technical solution, in actual use, workers can move the elastic clamping blocks to the corresponding middle position of the inner aluminum template according to the distribution of the front part of the inner aluminum template, so as to further improve its support stability.

[0021] Optionally, the elastic clamping block is made of polyurethane material.

[0022] By adopting the above technical solution and using polyurethane material to make elastic clamping blocks, the support effect is better.

[0023] Optionally, the distance between the back ribs in the layered configuration is 400mm-600mm.

[0024] By adopting the above technical solution, the distance between the layered back ribs is set between 400mm and 600mm, which provides better support.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. In actual operation, the external support is a diagonal brace, which directly supports and fixes the outer aluminum formwork by supporting the back ribs on the formwork. The internal support is a horizontal support, which can adapt to the limited internal space to support and reinforce the sides and front of the inner aluminum formwork.

[0027] 2. During use, the two side pressure plates are respectively installed and connected to the back ribs on both sides of the inner aluminum template. The worker holds the U-shaped handle with both hands to rotate and adjust the adjusting cylinder. The rotation of the adjusting cylinder drives the two threaded rods to move away from each other, so that the two connecting rods on each side drive the two first sliders to move away from each other until the side pressure plates are pressed tightly, thereby supporting and fixing the two sides of the inner aluminum template;

[0028] 3. During installation, the two side pressure plates are supported on the back ribs on both sides respectively. At the same time, the two first connecting seats on the side pressure plates are aligned with the two second connecting seats on the same side. Then, they are connected and fixed with bolts and nuts to make the side pressure plates removable and fixedly installed on the back ribs of the inner aluminum template. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses an aluminum profile template for casting in confined indoor spaces.

[0038] Reference Figure 1 The aluminum profile formwork for indoor confined space casting includes an outer aluminum formwork 1, an inner aluminum formwork 2, an outer support component, and an inner support component 4. The outer aluminum formwork 1 is arranged and spliced ​​along the outer boundary of the area to be cast 100, and adjacent outer aluminum formwork 1s are spliced ​​and fixed together using pins and tabs. Similarly, the inner aluminum formwork 2 is arranged and spliced ​​along the inner boundary of the area to be cast 100, and adjacent inner aluminum formwork 2s are spliced ​​and fixed together using pins and tabs. Corner plates are installed at corner positions for splicing, and the corner plates are spliced ​​and fixed to adjacent outer aluminum formwork 1s or inner aluminum formwork 2s using pins and tabs to form a casting space.

[0039] Both the inner aluminum template 2 and the outer aluminum template 1 are equipped with back ribs 5. The back ribs 5 on the inner aluminum template 2 and the outer aluminum template 1 are arranged in layers from top to bottom at intervals. In this embodiment, the distance between the layers of back ribs 5 is 500mm, and the back ribs 5 on the opposite inner aluminum template 2 and the outer aluminum template 1 are fixed together by tie rods. In other embodiments, the distance between the layers of back ribs 5 can be 450mm or 550mm, etc.

[0040] Reference Figure 1 , 2 The external support components are diagonal braces 3, which are laid at intervals along the outer aluminum formwork 1. Each diagonal brace 3 includes a ground gripping base 31, a lower support rod 32, and an upper support rod 33. The ground gripping base 31 is fixedly installed on the ground. The length of the lower support rod 32 is adjustable, with one end hinged to the ground gripping base 31 and the other end connected to and supported by the lower layer's back rib 5. Similarly, the length of the upper support rod 33 is adjustable, with one end hinged to the ground gripping base 31 and the other end connected to and supported by the middle layer's back rib 5, thus supporting and fixing the outer aluminum formwork 1 by supporting the back rib 5 on the outer aluminum formwork 1.

[0041] Reference Figure 1 , 3 The inner support members 4 are installed on the inner side and are arranged at intervals along the vertical direction. Each inner support member 4 is horizontally arranged and includes a bidirectional adjusting rod 41, side pressure plates 42 installed at both ends of the bidirectional adjusting rod 41, and a positive pressure plate 43 installed between the two side pressure plates 42. The two side pressure plates 42 are used to support and reinforce the two sides of the inner aluminum template 2, and the positive pressure plate 43 is used to support and reinforce the front part of the inner aluminum template 2.

[0042] Reference Figure 3 , 4 The bidirectional adjusting rod 41 includes an adjusting cylinder 411 and threaded rods 412 threaded to both ends of the adjusting cylinder 411. The threads at both ends of the adjusting cylinder 411 rotate in opposite directions, and a U-shaped handle 413 for worker adjustment is provided in the middle of the adjusting cylinder 411. Two connecting rods 44 are hinged to the ends of the threaded rods 412 away from the adjusting cylinder 411, and the two connecting rods 44 rotate in the same direction, allowing the ends of the two connecting rods 44 away from the threaded rod 412 to move towards or away from each other. Correspondingly, a first slide rail 421 is provided at the end of the side pressure plate 42 that connects to the connecting rods 44, and limit blocks 422 are provided at both ends of the first slide rail 421. Two first sliders 423 are slidably arranged inside the first slide rail 421, and the ends of the two connecting rods 44 away from the threaded rod 412 are respectively hinged to the two first sliders 423, allowing the two connecting rods 44 to drive the two first sliders 423 to move towards or away from each other.

[0043] During use, the two side pressure plates 42 are respectively installed and connected to the back ribs 5 on both sides of the inner aluminum template 2. The worker holds the U-shaped handle 413 with both hands to rotate and adjust the adjusting cylinder 411. The rotation of the adjusting cylinder 411 drives the two threaded rods 412 to move away from each other, so that the two connecting rods 44 on each side drive the two first sliders 423 to move away from each other until the side pressure plates 42 are pressed tightly, thereby supporting and fixing the two sides of the inner aluminum template 2.

[0044] Reference Figure 3 , 5Specifically, each end of the side pressure plate 42 is provided with a first connecting seat 45, and correspondingly, each of the two back ribs 5 is provided with two second connecting seats 46, and both the first connecting seats 45 and the second connecting seats 46 are provided with connecting holes. During installation, the two side pressure plates 42 are supported on the back ribs 5 on both sides respectively, and the two first connecting seats 45 on the side pressure plate 42 are aligned with the two second connecting seats 46 on the same side, so that the connecting holes on the first connecting seats 45 are aligned with the connecting holes on the second connecting seats 46. Then, they are connected and fixed with bolts and nuts, so that the side pressure plate 42 can be removed and fixedly installed on the back rib 5 of the inner aluminum template 2.

[0045] Reference Figure 3 In this embodiment, two retractable guide rods 47 are installed between the two side pressure plates 42. These two retractable guide rods 47 are arranged parallel to each other, and their ends are fixed perpendicularly to the two side pressure plates 42. In actual use, by setting the retractable guide rods 47, auxiliary guides can be provided for the relative movement of the two side pressure plates 42, thereby further improving the stability of their movement.

[0046] Reference Figure 3 , 4 Specifically, in this embodiment, the positive pressure plate 43 includes a left pressure plate 431, a right pressure plate 432, and a guide slide rod 433 installed between the left pressure plate 431 and the right pressure plate 432. In this embodiment, there are two guide slide rods 433, which are arranged parallel to each other and fixedly installed on the left pressure plate 431. The end of each guide slide rod 433 away from the left pressure plate 431 is slidably inserted into the right pressure plate 432. Guide push rods 434 are fixed to the back sides of both the left and right pressure plates 431 and 432. The two guide push rods 434 slide through the innermost limiting block 422 and extend into the first slide rail 421.

[0047] In practical application, firstly, when the side pressure plate 42 needs to be installed on the corresponding back rib 5, the positive pressure plate 43 will be lengthened or shortened accordingly as the distance between the two side pressure plates 42 is adjusted. Secondly, when the inner support member 4 is fixed and adjusted by rotating the adjusting cylinder 411, the two connecting rods 44 on the threaded rod 412 control the two first sliders 423 to move away from each other. At this time, the first sliders 423 push the guide push rod 434 outward to push the left pressure plate 431 and the right pressure plate 43 of the positive pressure plate 43 to press against the front part of the inner aluminum template 2 to support and reinforce it. Thirdly, when the inner support member 4 tilts in the front-back direction due to installation errors, the positive pressure plate 43 can be adaptively deflected relative to the guide push rod 434, so that the positive pressure plate 43 can press against the front part of the inner aluminum template 2 in a positive direction to further improve its pressing stability.

[0048] In this embodiment, a second slide rail 435 is fixedly installed on the top of both the left pressure plate 431 and the right pressure plate 432, and the second slide rail 435 extends along the length of the corresponding left pressure plate 431 or right pressure plate 432. A second slider is slidably mounted on the second slide rail 435, and an elastic abutment block 436 made of polyurethane material is fixedly installed on the second slider, with the elastic abutment block 436 protruding outward relative to the corresponding left pressure plate 431 or right pressure plate 432. In actual use, workers can move the elastic abutment block 436 to the corresponding middle position of the inner aluminum template 2 for abutment support according to the distribution of the front part of the inner aluminum template 2, thereby further improving its support stability.

[0049] The implementation principle is as follows:

[0050] During construction, spliced ​​outer aluminum formwork 1 is arranged along the outer boundary of the area to be poured 100, and adjacent outer aluminum formwork 1 are spliced ​​and fixed together with pins and tabs. Spliced ​​inner aluminum formwork 2 is arranged along the inner boundary of the area to be poured 100, and adjacent inner aluminum formwork 2 are spliced ​​and fixed together with pins and tabs. Corner plates are installed at the corner positions for splicing, and the corner plates are spliced ​​and fixed to the adjacent outer aluminum formwork 1 or inner aluminum formwork 2 with pins and tabs to form a pouring space.

[0051] Install back ribs 5 on the outer aluminum template 1 and the inner aluminum template 2, with the back ribs 5 arranged in layers at intervals from top to bottom. Then, use tie rods to fix the oppositely arranged back ribs 5 together.

[0052] Install diagonal bracing 3 to support and reinforce the external aluminum formwork 1.

[0053] The inner support members 4 are installed layer by layer along the back ribs 5 of the inner aluminum template 2. When installing a single inner support member 4, the two side pressure plates 42 of the inner support member 4 are first supported on the back ribs 5 on both sides, and the first connecting seat 45 on the side pressure plate 42 is fixed to the second connecting seat 46 on the back rib 5 with bolts and nuts. Then, the adjusting cylinder 411 is rotated to drive the two threaded rods 412 to move away from each other, so that the two connecting rods 44 on each side drive the two first sliders 423 to move away from each other until the first sliders 423 press against the limiting block 422 and press the side pressure plates 42, thereby supporting and fixing the two sides of the inner aluminum template 2. At the same time, during this process, the first sliders 423 push the guide push rod 434 outward to push the left pressure plate 431 and the right pressure plate 432 of the positive pressure plate 43 against the front part of the inner aluminum template 2 to support and reinforce it.

[0054] This application also discloses an installation method for aluminum profile modules, used for installing the aforementioned aluminum profile modules for indoor confined space casting, comprising the following steps:

[0055] S1. Arrange spliced ​​outer aluminum formwork 1 along the outer boundary of the area to be poured 100, and fix adjacent outer aluminum formwork 1 with pins and tabs. Arrange spliced ​​inner aluminum formwork 2 along the inner boundary of the area to be poured 100, and fix adjacent inner aluminum formwork 2 with pins and tabs. Set corner plates at the corner positions for splicing, and fix the corner plates to the adjacent outer aluminum formwork 1 or inner aluminum formwork 2 with pins and tabs to form a pouring space. S2. Install back ribs 5 on the outer aluminum formwork 1 and inner aluminum formwork 2, and set the back ribs 5 in layers from top to bottom. Then, fix the oppositely set back ribs 5 with tie rods. S3. Install diagonal braces 3 to support and reinforce the outer aluminum formwork 1. S4. Install inner support members 4 layer by layer along the layered back ribs 5 on the inner aluminum formwork 2. When installing a single inner support member 4, firstly, the two side pressure plates 42 of the inner support member 4 are respectively supported on the back ribs 5 on both sides, and the first connecting seat 45 on the side pressure plate 42 and the second connecting seat 46 on the back rib 5 are fixed with bolts and nuts. Next, the adjusting cylinder 411 is rotated to drive the two threaded rods 412 to move away from each other, so that the two connecting rods 44 on each side drive the two first sliders 423 to move away from each other until the first sliders 423 press against the limiting block 422 and press the side pressure plate 42, thereby supporting and fixing the two sides of the inner aluminum template 2. At the same time, during this process, the first sliders 423 push the guide push rod 434 outward to push the left pressure plate 431 and the right pressure plate 432 in the positive pressure plate 43 to press against the front part of the inner aluminum template 2 to support and reinforce it.

[0056] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals.
