Description

Technical Field

[0001] The utility model relates to the technical field of building installation, and in particular to a pre-buried sleeve device for an aluminum formwork support structure. Background Technology

[0002] The full name of aluminum alloy formwork is concrete engineering aluminum alloy formwork. It is a new generation of formwork system after plywood formwork, combined steel formwork system, steel frame wood (bamboo) plywood system, large formwork system, and early dismantling formwork system. Aluminum alloy formwork has the characteristics of light weight, good pressure-bearing conditions of the formwork, and convenient mechanized and rapid construction of concrete. Now most residential projects use this type of formwork system for construction. In the case of large-scale use of aluminum alloy formwork in new construction projects, it is necessary to study the precise pre-embedded technology of electromechanical installation in conjunction with aluminum formwork construction. Therefore, the installation project needs to adapt to the construction of the aluminum formwork system, and conduct detailed management research based on the advantages and disadvantages of the aluminum formwork to reduce construction costs and improve construction efficiency.

[0003] When installing the aluminum formwork support structure, it is necessary to install the embedded sleeve. The sleeve dedicated to the aluminum formwork is mainly set inside the wall and between the outer formwork to bear the lateral pressure and other loads of the concrete. The embedded sleeve can also ensure that the spacing between the inner and outer formworks meets the design requirements. At present, the traditional installation and fixing method of the sleeve is to tie or weld the sleeve to the steel bars in the structural beam, which requires hot work and poses a great fire safety hazard. In addition, the sleeve in the beam is affected by the steel bars and formwork, the operating space is limited, the construction efficiency is extremely low, and there is a risk of affecting the construction progress. In addition, each installation of a sleeve requires a dedicated person to measure and lay out the lines between the formworks on both sides. The manual positioning error is large, the operation is inconvenient, and it is very easy to cause quality defects. Therefore, a large amount of manpower and machinery are required during the installation, and the manual error is large, and there is a cost risk of rework.

[0004] Therefore, there is an urgent need for an embedded sleeve device for the aluminum mold support structure to solve the problem of inconvenient installation of the embedded sleeve required for the aluminum mold support structure. Contents of utility model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a pre-buried sleeve device for an aluminum mold support structure to solve the problem of inconvenient installation of the pre-buried sleeve required for the aluminum mold support structure.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An embedded sleeve device for an aluminum formwork support structure, characterized in that: it includes an embedded sleeve, at least two connecting rods, a plug, a nut and an elastic connecting member. Plug heads are installed at both ends of the embedded sleeve with openings. Through sliding connection holes are provided in both plug heads at both ends. Nuts are installed on the rod bodies of the connecting rods. The connecting rods are arranged in the inner cavity of the embedded sleeve, and the ends of at least two connecting rods respectively extend out from the sliding connection holes of the plug heads at both ends in opposite directions. The connecting rods are telescopically and slidably arranged in the sliding connection holes. The nuts are used to limit the length of the connecting rods extending out. An elastic connecting member is correspondingly connected between the nuts of the connecting rods at both ends of the embedded sleeve. The elastic connecting member is used to provide a thrust for the connecting rods at both ends to extend outwards from the sliding connection holes.

[0008] To optimize the above technical solution, the specific measures taken also include:

[0009] Further, the rod body of the connecting rod is divided into a smooth rod structure and a threaded rod structure. The nut is threadedly connected to the connecting rod through the threaded rod structure of the connecting rod. The end of the smooth rod structure of the connecting rod is used to insert into and extend out from the sliding connection hole of the plug head. The end of the threaded rod structure of the connecting rod is located in the inner cavity of the embedded sleeve.

[0010] Further, the elastic connecting member includes a spring and a sleeve. Coaxial sliding connection holes are respectively provided in the plug heads at both ends. A sleeve communicating with the sliding connection holes at both ends is provided between the plug heads at both ends. The nut on the connecting rod is slidably arranged in the inner cavity of the sleeve. The spring is arranged in the sleeve, and both ends of the spring are respectively connected to the nuts of the connecting rods at both ends.

[0011] Further, the spring is made of carbon spring steel.

[0012] Further, the plug head has a structure with a "T"-shaped side cross-section. The lower end of the "T"-shaped structure of the plug head is a connecting block, which is used to insert into the end opening of the embedded sleeve for detachable connection with the embedded sleeve. The outer diameter of the connecting block is the same as the inner diameter of the embedded sleeve. The upper end of the "T"-shaped structure of the plug head is a circumferential limiting edge, and the outer diameter of the limiting edge is the same as the outer diameter of the embedded sleeve.

[0013] Further, the axial width of the connecting block is wider than the axial width of the limiting edge.

[0014] Further, the total length of the connecting rods at both ends of the embedded sleeve is not longer than the axial width of the embedded sleeve.

[0015] Further, each sliding connection hole of the plug head is provided with one and is located at the center position of the plug head.

[0016] The beneficial effects of the present utility model are:

[0017] Through the cooperative setting of the connecting rod, nut, plug and elastic connecting member, both ends of the embedded casing are provided with connecting rods that can extend or retract into the embedded casing. At the same time, the connecting rod and the embedded casing are restrictively connected through the plug, ensuring the reliability of the structure. The elastic connecting member is used to provide the thrust for the connecting rods at both ends to extend outwards from the sliding connection holes, so as to ensure that the connecting rods can extend out again as needed after retracting into the embedded casing. During use, construction workers can directly perform measurement and positioning on the outer sides of the two side formworks, and open through holes for the connecting rods to insert. Then, the connecting rods at both ends are pushed into the inner cavity of the embedded casing, and the embedded casing is stuffed between the two side formworks. After reaching the designated position, the connecting rods naturally pop out and are clamped in the corresponding through holes to complete the rapid positioning and installation of the embedded casing. When using this device, there is no need for construction workers to perform measurement and positioning in the narrow space between the two side formworks. Direct external measurement and positioning can be carried out, which can further ensure the convenience and accuracy of construction.

[0018] In the case where a large number of aluminum alloy formworks are used in new construction projects, the casing embedding device for the aluminum formwork structure proposed by the present utility model will have a wide application prospect. Moreover, the formwork installation positions between the floors of the aluminum formwork structure in the standard floors are the same, and the embedding positions of each embedded casing are also the same. After positioning the casing in the first standard floor, the aluminum alloy formworks through which the connecting rods at both ends of the device of the present utility model pass will be installed at the same position in the next standard floor. When embedding the casing, only position verification is required to complete the casing embedding, which greatly improves the production efficiency and reduces the manual positioning errors during the casing embedding between floors.

[0024] The present utility model will be described in detail below with reference to the accompanying drawings.

[0025] As shown in the Figure 1 and Figure 4 accompanying drawings, a pre-embedded sleeve device for an aluminum formwork support structure according to an embodiment of the present utility model includes a pre-embedded sleeve 8, at least two connecting rods, a plug, a nut, and an elastic connecting member 3. Plugs are respectively installed at both ends of the pre-embedded sleeve 8 with openings at both ends. The plugs are relatively fixed to the pre-embedded sleeve 8. Sliding connection holes penetrating up and down are provided in the plugs at both ends. Nuts are installed on the rod bodies of the connecting rods. The connecting rods are arranged in the inner cavity of the pre-embedded sleeve 8, and the ends of at least two connecting rods respectively extend out from the sliding connection holes of the plugs at both ends in opposite directions. The connecting rods are telescopically slidably arranged in the sliding connection holes. The nuts are used to abut against the plugs to limit the length of the connecting rods extending out. An elastic connecting member 3 is correspondingly connected between the nuts of the connecting rods at both ends of the pre-embedded sleeve 8. The elastic connecting member 3 is used to provide a thrust for the connecting rods at both ends to extend outwards from the sliding connection holes.

[0026] Through the cooperative setting of the connecting rods, nuts, plugs, and elastic connecting member 3 of the present utility model, the two ends of the pre-embedded sleeve 8 are provided with connecting rods that can extend or retract into the pre-embedded sleeve 8. At the same time, the connecting rods and the pre-embedded sleeve 8 are restrictively connected through the plugs, ensuring the reliability of the structure. The elastic connecting member 3 is used to provide a thrust for the connecting rods at both ends to extend outwards from the sliding connection holes, so as to ensure that the connecting rods can extend out again as needed after retracting into the pre-embedded sleeve 8. During use, construction workers can directly perform measurement and positioning on the outer sides of the two side formworks, and open through holes for the connecting rods to be inserted. Then, the connecting rods at both ends are pushed into the inner cavity of the pre-embedded sleeve 8, and the pre-embedded sleeve 8 is inserted between the two side formworks. After reaching the designated position, the connecting rods naturally pop out and are clamped in the corresponding through holes to complete the rapid positioning and installation of the pre-embedded sleeve 8. When using this device, it is not necessary for construction workers to perform measurement and positioning in the narrow space between the two side formworks. Direct outer side measurement and positioning can be carried out, which can further ensure the convenience and accuracy of construction. In this embodiment, the two side formworks can be the upper and lower sides or the left and right sides.

[0027] As shown in the Figure 3As shown, in a specific embodiment, the rod body of the connecting rod is divided into a smooth rod structure and a threaded rod structure. The nut is threadedly connected to the connecting rod through the threaded rod structure of the connecting rod. The end of the smooth rod structure of the connecting rod is used to insert into and extend out of the sliding connection hole of the plug. The end of the threaded rod structure of the connecting rod is located in the inner cavity of the embedded sleeve 8. In this way, the adjustability of the device can be increased through the threaded connection between the threaded rod structure of the connecting rod and the nut. The length of the connecting rod used can be adjusted as needed according to the thickness of the templates on both sides, that is, the extendable length of the connecting rod can be adjusted as needed. Through the setting of the smooth rod structure of the connecting rod, the smoothness of the connection between the connecting rod and the sliding connection hole of the plug can be ensured, so as to ensure that the connecting rod can pop out smoothly during use.

[0028] As shown in the attached Figure 2 figure, in a specific embodiment, the elastic connection member 3 includes a spring and a sleeve 7. The plugs at both ends are respectively provided with coaxial sliding connection holes. A sleeve 7 communicating the sliding connection holes at both ends is provided between the plugs at both ends. The nut on the connecting rod is slidably arranged in the inner cavity of the sleeve 7. The connecting rod is slidably connected to the sleeve 7 through the nut. The spring is arranged in the sleeve 7, and both ends of the spring are respectively connected to the nuts of the connecting rods at both ends, and provide a thrust for the connecting rods at both ends to extend out of the sliding connection holes. In this way, during use, the spring can be constrained by the sleeve 7, so as to ensure that the spring can effectively provide the required thrust to the connecting rods at both ends. Among them, the spring can be made of carbon spring steel.

[0029] In a specific embodiment, the plug has a structure with a "T"-shaped cross-section. The lower end of the "T"-shaped structure of the plug is a connecting block, which is used to insert into the end opening of the embedded sleeve 8 for detachable connection with the embedded sleeve 8. The outer diameter of the connecting block is the same as the inner diameter of the embedded sleeve 8. The upper end of the "T"-shaped structure of the plug is a ring of limiting edges, and the outer diameter of the limiting edges is the same as the outer diameter of the embedded sleeve 8. In this way, the detachable and stable connection between the "T"-shaped plug and both ends of the embedded sleeve 8 can be realized, so as to increase the adjustability and reusability of the device. At the same time, the reliability of the connection with the embedded sleeve 8 can be ensured through the structure of the plug.

[0030] The axial width of the connecting block is wider than the axial width of the limiting edge. In this way, the reliability of the connection can be ensured, and at the same time, it is convenient for calculating and selecting the width of the required embedded sleeve 8.

[0031] In a specific embodiment, the total length of the connecting rods at both ends of the embedded sleeve 8 is not longer than the axial width of the embedded sleeve 8. In this way, it can be ensured that the connecting rods at both ends can be completely received in the embedded sleeve 8.

[0032] Among them, in a specific embodiment, each plug has one sliding connection hole, which is located at the center of the plug. In this way, while ensuring the use effect of the device, the structure of the device can be streamlined, and the convenience of using the device can be increased.

[0033] A specific implementation manner of the device of the present utility model includes an adjustable and detachable upper connecting rod 1 and a lower connecting rod 5, an upper nut 2 and a lower nut 4 that can be respectively threadedly connected to the upper connecting rod 1 and the lower connecting rod 5, a steel sleeve 7 made of thickened material and with a smooth inner surface, and an upper plug 6 and a lower plug 9.

[0034] The upper plug 6 and the lower plug 9 are made of the same material as the embedded casing 8, and are composed of two hollow cylinders, a connecting block at the slightly longer end with the same inner diameter as the required embedded casing 8, and a limiting edge at the slightly shorter end with the same outer diameter as the required embedded casing 8. The connecting block can penetrate into the embedded casing 8, and the limiting edge seals the embedded casing 8 to prevent mortar from pouring in.

[0035] The thread depth and diameter of the upper nut 2 and the lower nut 4 are matched with the corresponding upper connecting rod 1 and the lower connecting rod 5, and the use lengths of the upper connecting rod 1 and the lower connecting rod 5 can be adjusted according to the size of the aluminum formwork structure. At the same time, the elastic connecting member 3, the upper connecting rod 1, the lower connecting rod 5, the detachable upper plug 6 and the lower plug 9 can be removed after the aluminum formwork is removed during the embedded casing pre-embedding of the aluminum formwork structure once, and can be reused in the embedded casing pre-embedding of another group of aluminum formwork structures in the later stage.

[0036] Among them, the diameter φ of the upper connecting rod 1 and the lower connecting rod 5 can be determined according to the length of the embedded casing 8. A φ = 10MM galvanized screw rod can be selected, with a single length of 250MM and an effective thread length of 120MM. The thread direction is opposite to the thread rotation direction of the corresponding upper nut 2 and lower nut 4, and the thread can be firmly connected to the nut and can also be removed later.

[0037] Among them, the elastic coefficient and the component length of the elastic connecting member 3 that plays a telescopic role in the central part can be determined according to the length of the embedded casing 8. A 70# carbon spring steel with a natural length of 500MM and a wire diameter φ = 2.0MM can be selected. Both ends of the carbon spring steel tightly abut against the corresponding upper nut 2 and lower nut 4.

[0038] Among them, the length of the sleeve 7 in the central part can be determined according to the length of the embedded casing 8. A galvanized steel pipe with a length of 360MM and a wall thickness of 3.0MM can be selected.

[0039] Among them, the sizes of the upper end plug 6 and the lower end plug 9 can be determined according to the size of the pre-embedded sleeve 8. The slightly longer end can be selected with a length of 50 MM and a diameter φ = 150MM, and the slightly shorter end with a length of 20 MM and a diameter φ = 160MM. A sliding connection hole with a diameter φ = 10MM is provided at the center of the plug for the ends of the upper connecting rod 1 and the lower connecting rod 5 to pass through.

[0040] The processing of the above-mentioned components, including the threads of the upper connecting rod 1 and the lower connecting rod 5, etc., is customized by the manufacturer according to the length and thread and other parameter technical standards of each component, so that the upper connecting rod 1 and the lower connecting rod 5 can be used in combination with the upper nut 2 and the lower nut 4, and an appropriate amount of engine oil is added to the threaded screwing contact part for easy connection and disassembly. The plugs and the sleeve 7 are both made by cutting and welding. The welding quality requirements are full, smooth, slag-free, bubble-free, and anti-corrosion treatment is carried out. The elastic connecting member 3 at the central part can be preset according to the size and length of the actual pre-embedded sleeve 8.

[0041] When the utility model is in use, it includes the following steps:

[0042] Step 1, before the installation of the civil engineering aluminum formwork structure is completed, position the position of the required pre-embedded sleeve 8 and make marks to complete the preparatory work for the installation of the pre-embedded sleeve.

[0043] Step 2, after the aluminum formwork structure is initially connected, rotate the corresponding upper nut 2 and lower nut 4 on the upper connecting rod 1 and the lower connecting rod 5 as required to adjust the use length of the upper connecting rod 1 and the lower connecting rod 5, and the screwing length is the same. Then, set the adjusted upper connecting rod 1 and lower connecting rod 5 at 180 degrees and complete the assembly of the device.

[0044] Step 3, push the upper connecting rod 1 and the lower connecting rod 5 at both ends of the device assembled in Step 2 until the end faces are flush with the corresponding upper end plug 6 and lower end plug 9 respectively.

[0045] Step 4, finally, open a through hole with the same diameter as the connecting rod at the position of the pre-embedded sleeve 8 required by the positioned aluminum formwork structure, place the pre-embedded sleeve 8 in Step 3 at the designated position on both sides of the aluminum formwork structure, and the upper connecting rod 1 and the lower connecting rod 5 on it respectively pass through the opened through holes to play a fixing role and are convenient for disassembly.

[0046] Principle of the solution of this utility model: This device is based on its application in the embedded sleeve of the aluminum formwork structure. The key points and difficulties are to ensure the accurate positioning of the embedded sleeve 8 and prevent the dislocation of the sleeve. Therefore, first, the quality control of the embedded sleeve 8 in terms of wall thickness and strength is carried out, and then through the structural settings such as the upper connecting rod 1 and the lower connecting rod 5, the installation and disassembly of the embedded sleeve 8 are facilitated. At the same time, the elastic connection member 3 is used to ensure the adjustability of the upper connecting rod 1 and the lower connecting rod 5, which can meet the requirements of adjustable, detachable and reusable internal support during the embedded installation of the mechanical and electrical installation sleeve of the aluminum formwork structure.
