Description

Technical Field

[0001] The utility model belongs to the technical field related to construction, in particular to a template for pouring concrete load-bearing columns. Background Art

[0002] During the construction of existing buildings, the load-bearing columns are usually cast on-site with concrete to ensure sufficient structural strength and load-bearing capacity. As concrete is a fluid, it must be used in conjunction with a corresponding formwork to be shaped after pouring. The building formwork is a temporary supporting structure made according to design requirements to shape the concrete structure and components according to the specified position and geometric dimensions, maintain their correct position, and bear the self-weight of the building formwork and the external loads acting on it. Existing building formworks mostly use aluminum formworks for casting, but the relevant formworks still have the following disadvantages in actual use:

[0003] 1. Since most of the templates are not disposable and need to be recycled for multiple times, most of them are assembled structures. As load-bearing columns, a large amount of concrete must be poured, which requires the connection between the templates to be tighter and the bearing pressure to be stronger. Conventional templates are mainly composed of panels, supporting structures and connectors. Usually, the panels are connected with connectors and then supported by supporting structures. All the pressure generated during concrete pouring is on several connectors. Once the strength of the connection is insufficient, it is easy to be damaged or even leak. Therefore, the connection and assembly method of the template still needs to be optimized;

[0004] 2. Secondly, if the formwork is supported by only two supporting structures, two problems need to be considered. First, once the supporting part slips, it is easy to cause uneven force on the formwork, resulting in a certain impact on the subsequent pouring. Second, relying solely on the support structure can only support the force locally, and it is impossible to reinforce all the formwork combinations, which will also lead to insufficient structural strength of the connection. Utility Model Content

[0005] The purpose of the utility model is to provide a formwork for pouring concrete load-bearing columns. By arranging side forms, angle forms, reinforcement structures, support rods and pads, the problems of insufficient firmness and tightness of the formwork connection and uneven force as well as insufficient strength of the support and connection structure of the formwork are solved.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is a template for pouring concrete load-bearing columns, comprising four side molds, four corner molds, two reinforcement structures and four pads, wherein the four side molds surround each other to form a columnar structure with a rectangular inner cavity, and an angle mold is inserted between every two adjacent side molds, and limiting grooves are provided on both sides of each side mold, and limiting strips are fixed on the two right-angled surfaces of each corner mold, and the limiting strips on the two right-angled surfaces of the corner mold are respectively inserted into the adjacent limiting grooves on the two adjacent side molds;

[0008] The outer sides of the four side molds are surrounded by two reinforcement structures; a pad is placed at the bottom of the outer surface of each side mold;

[0009] The reinforcement structure includes four right-angle blocks and four locking components. A locking component is arranged between two adjacent right-angle blocks. The locking component includes an internal threaded tube 2 and a fixed screw fixed to one end of the internal threaded tube 2, and the other end of the internal threaded tube 2 is threadedly screwed with a movable screw. An internal threaded tube 1 is embedded in both ends of the right-angle block. The fixed screw and the movable screw in one locking component are respectively screwed into adjacent internal threaded tubes 1 in two adjacent right-angle blocks.

[0010] Furthermore, a groove is provided on the outer side surface of the side mold, and crisscross reinforcing ribs are provided in the groove. Two hinges are also fixed on the side mold where the groove is located, and each of the hinges is hingedly connected to a support rod.

[0011] Furthermore, a clamping hole is provided in the side mold at the bottom of the groove, a hook is fixed at the edge of the upper end of the pad close to the side mold, and the end of the hook away from the pad is inserted into the clamping hole.

[0012] Furthermore, a slide groove is provided on the pad, and limiting grooves are also provided in the pad on both sides of the slide groove. The bottom end of the support rod is located in the slide groove, and a limiting block is inserted in the limiting groove next to the bottom of the support rod, and the bottom of the support rod abuts against the side of the limiting block.

[0013] Furthermore, two groups of transverse slots are provided on the outer surface of the side mold outside the groove, each group of slots corresponds to a group of reinforcement structures, and a clip strip is fixed on the inner side of the right-angle block. The clip strip on the inner side of one right-angle block is respectively inserted into adjacent slots of two adjacent side molds.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model solves the problem that the template connection is not firm and tight enough and the force is uneven by setting side molds, corner molds and reinforcement structures; the four side molds are plugged and fixed to each other through four corner molds, so that they are completely unable to move in the horizontal direction, and the connected parts are relatively comprehensive, rather than several connecting parts are connected to each other. The coordinated connection of the corner molds and the side molds makes the overall template structure more stable, the connection is relatively firm and tight, and there is almost no large gap. The corner molds are plugged in through limit strips of the same height as the side molds, so that the connection surface is wider and more stable, and the subsequent force is more even, rather than the force is distributed on several connecting parts.

[0016] 2. The utility model solves the problem of insufficient strength of the support and connection structure of the formwork by setting a reinforcement structure, support rods and pads; after the corner form and the side form are connected with each other, two sets of reinforcement structures are used for stable connection, and all the side forms and the corner form are further connected together to make them more stable, and finally, multiple support rods are used for oblique support, and the design of the pad is used to form a triangular structure between the pad, support rod and side form, making it more stable. Secondly, a limiting block for limiting the support rod is set on the pad to avoid the support rod from slipping, thereby further increasing the structural strength and providing more sufficient bearing pressure.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] See also Figure 1-9 As shown, the utility model is a template for pouring concrete load-bearing columns, comprising four side molds 1, four corner molds 2, two reinforcement structures 3 and four pads 4. The four side molds 1 surround each other to form a columnar structure with a rectangular inner cavity, and a corner mold 2 is inserted between every two adjacent side molds 1. Both sides of each side mold 1 are provided with limiting grooves 105, and limiting strips 201 are fixed on the two right-angled surfaces of each corner mold 2, and the limiting strips 201 on the two right-angled surfaces of the corner mold 2 are respectively inserted into the adjacent limiting grooves 105 on the two adjacent side molds 1;

[0031] Each corner mold 2 is inserted into two adjacent side molds 1 through the limiting strips 201 on its two right-angled surfaces, so that the two adjacent side molds 1 form a right-angle structure distribution, and the connection surface is larger and the connection is more stable. The cross section of the limiting strip 201 is a T-shaped structure. Unless it is completely broken, it is impossible to detach in the horizontal direction, thereby ensuring a stable connection. According to the above operation, the four corner molds 2 and the four side molds 1 are completely combined to form a structure with a rectangular inner cavity, and concrete is poured into the inner cavity formed by it;

[0032] The outer sides of the four side molds 1 are surrounded by two reinforcement structures 3; a pad 4 is placed at the bottom of the outer surface of each side mold 1;

[0033] The reinforcement structure 3 includes four right-angle blocks 301 and four locking components 302. A locking component 302 is provided between two adjacent right-angle blocks 301. The locking component 302 includes an internal threaded tube 3021 and a fixed screw 3022 fixed to one end of the internal threaded tube 3021. The other end of the internal threaded tube 3021 is threadedly screwed with a movable screw 3023. The two ends of the right-angle block 301 are embedded with an internal threaded tube 3012. The fixed screw 3022 and the movable screw 3023 in one locking component 302 are respectively screwed into the adjacent internal threaded tubes 3012 in the two adjacent right-angle blocks 301.

[0034] After the side mold 1 and the corner mold 2 are assembled, the reinforcement structure 3 is sleeved on the outside of the side mold 1, and each right-angle block 301 is clamped on two adjacent side molds 1, and then the locking assembly 302 is used to lock and connect the adjacent right-angle blocks 301; for example, the fixed screw 3022 in the locking assembly 302 is first screwed into the internal threaded tube 1 3012 of the right-angle block 301 (the internal threaded tube 2 3021 rotates synchronously with it during this process), and then the movable screw 3023 is selected from the internal threaded tube 2 3021 until it enters the internal threaded tube 1 3012 of the adjacent right-angle block 301, thereby realizing the connection between two adjacent right-angle blocks 301, until all right-angle blocks 301 are connected, the reinforcement structure 3 completely locks and restricts all side molds 1, increases the pressure-bearing capacity, and improves the overall structural strength.

[0035] The outer side surface of the side mold 1 is provided with a groove 101, and the groove 101 is provided with crisscross reinforcing ribs 102. Two hinges 103 are also fixed on the side mold 1 where the groove 101 is located, and each hinge 103 is hingedly connected to a support rod 104;

[0036] The setting of the groove 101 saves material waste, and is combined with the reinforcing rib 102 to strengthen the structure and ensure structural strength. The hinge 103 is hingedly connected to the support rod 104, and the support rod 104 is tilted to support the side mold 1 to increase the force distribution points.

[0037] A clamping hole 1012 is provided in the side mold 1 at the bottom of the groove 101, a hook 402 is fixed at the upper end of the pad 4 near the edge of the side mold 1, and the end of the hook 402 away from the pad 4 is inserted into the clamping hole 1012;

[0038] When the backing plate 4 is connected to the side mold 1, the hook 402 on the backing plate 4 is fitted into the clamping hole 1012 in the side mold 1, and the splicing can be easily completed.

[0039] A slide groove 401 is formed on the backing plate 4, and limiting grooves 4011 are formed in the backing plate 4 on both sides of the slide groove 401. The bottom end of the support rod 104 is located in the slide groove 401, and a limiting block 403 is inserted into the limiting groove 4011 beside the bottom of the support rod 104, and the bottom of the support rod 104 abuts against the side of the limiting block 403.

[0040] After the support rod 104 is tilted, the bottom is placed in the slide groove 401 as close to the side form 1 as possible until it cannot get any closer. Then, the limiting block 403 is inserted into the limiting groove 4011 beside the support rod 104 to limit the support rod 104 and prevent it from slipping and loosening after being stressed. At this time, the side form 1, the pad 4, and the support rod 104 form a triangular structure to make it more stable. After pouring concrete, the pad 4 is connected to the side form 1 due to the bent hook 402 and will not separate from the side form 1.

[0041] Two groups of transverse slots 1011 are provided on the outer surface of the side mold 1 outside the groove 101, and each group of slots 1011 corresponds to a group of reinforcement structures 3. A clip strip 3011 is fixed on the inner side of the right-angle block 301, and the clip strip 3011 on the inner side of a right-angle block 301 is respectively inserted into the adjacent slots 1011 of two adjacent side molds 1;

[0042] When installing the reinforcement structure 3, firstly match the card strip 3011 in the right-angle block 301 with the card slot 1011 on the two adjacent side molds 1, and then install the locking assembly 302 after corresponding connection, so that the reinforcement structure 3 has a certain limit support, will not shift the position, will not tilt during the installation process, and will not slide due to gravity.

[0043] The specific working principle of the utility model is as follows: each corner mold 2 is plugged into two adjacent side molds 1 through the limiting strips 201 on its two right-angled surfaces, so that the two adjacent side molds 1 form a right-angle structure distribution, until the four corner molds 2 and the four side molds 1 are completely combined to form a structure with an inner cavity of a rectangular parallelepiped, and then the reinforcement structure 3 is sleeved on the outside of the side mold 1, and the card strip 3011 in the right-angle block 301 is first matched with the card groove 1011 on the two adjacent side molds 1, and after the corresponding plug-in, the locking component 302 is installed, and the fixed screw 3022 in the locking component 302 is first screwed into the internal threaded tube 1 3012 of the right-angle block 301 (the internal threaded tube 2 3021 rotates synchronously with it during this process), and then the movable screw 3023 is removed from the internal thread Select from the second threaded tube 3021 until it enters the internal threaded tube 1 3012 of the adjacent right-angle block 301, thereby realizing the connection between the two adjacent right-angle blocks 301, until all the right-angle blocks 301 are connected and the installation of the reinforcement structure 3 is completed. After the installation of the two groups of reinforcement structures 3 is completed, the hook 402 on the pad 4 is put into the card hole 1012 in the side mold 1, and the splicing can be simply completed. Then, after the support rod 104 is tilted, the bottom is placed in the slide groove 401 as close to the side mold 1 as possible until it cannot be close, and then the limiting block 403 is inserted into the limiting groove 4011 beside the support rod 104 to limit the support rod 104. After the assembly is completed, concrete can be poured into the inner cavity formed by the side mold 1 to form a load-bearing column.
