Description

Technical Field

[0001] This utility model relates to the field of precast concrete components, and in particular to a green building material precast concrete component structure. Background Technology

[0002] Precast concrete components are concrete components that are pre-cast, molded, and cured in a factory or on-site before being transported to the construction site for installation. They are used in the fields of architecture, bridges, and municipal engineering. The factory production environment is stable, and the mix proportion, casting process, and curing conditions can be controlled, reducing human error in on-site construction. The strength and dimensional accuracy of the components are superior to those of traditional cast-in-place structures.

[0003] A search revealed Chinese Patent Publication No. CN215564564U, which discloses a green building material precast concrete component structure, relating to the technical field of precast concrete components. The green building material precast concrete component structure includes a load-bearing block. Longitudinal movable grooves are formed on both sides of the load-bearing block, and transverse movable grooves are formed at both ends of the load-bearing block. A clamping mechanism is hinged between the transverse and longitudinal movable grooves. The clamping mechanism includes a movable ring. Multiple first hinge posts are hinged to the outer sides of both sides of the movable ring. Placement rings are fixedly connected to the outer sides of the first hinge posts. Clamping rings are hinged to the inner sides of the placement rings, and multiple clamping rings are also provided. Clamping components are hinged between the clamping rings. The design of this utility model, with its clamping ring, movable ring, and support ring working together, achieves fixed positioning of pre-constructed components, reducing the labor intensity of workers and improving construction efficiency. However, in actual use, after installation and casting, an external insulation layer needs to be installed. But the connection between the external insulation layer and the structural layer can crack due to thermal expansion and contraction, leading to insulation failure or water seepage, which affects the service life of subsequent concrete components and product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a green building material precast concrete component structure, which aims to improve the existing technology that requires the additional installation of an external insulation layer. However, the connection between the external insulation layer and the structural layer will crack due to thermal expansion and contraction, leading to insulation failure or water seepage, thereby affecting the service life of subsequent concrete components and product quality.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a green building material precast concrete component structure, including multiple fixing rods, each fixing rod having a connecting mechanism on its outer wall to improve the service life of the concrete component; each connecting mechanism having a weathering mechanism inside to enhance the weather resistance of the connecting mechanism; each connecting mechanism includes multiple connecting plates, the inner walls of which are slidably mounted on the outer walls of corresponding fixing rods; each top connecting plate has a support component at its bottom; multiple engaging grooves are formed in the middle of adjacent sides of each connecting plate; multiple positioning bolts are threadedly connected to the opposite sides of each connecting plate; a fixing plate is threadedly connected to the end of each positioning bolt; a weathering plate is fixedly connected to one side of each fixing plate; mounting sleeves are fixedly installed on the left and right ends of each fixing rod; and connecting rods are fixedly installed on the inner walls of each mounting sleeve.

[0006] The above technical solution enables the installation of the structure by interlocking multiple connecting plates and fixing plates with the support components. Then, by rotating the positioning bolts, the fixing plates and connecting plates can be locked in place. At the same time, in conjunction with the weathering plate, the weathering plate and the concrete component are integrated into one, thus avoiding the impact of thermal expansion and contraction on the service life of the component during the installation of the external weathering plate, and thus effectively increasing the quality of the product.

[0008] The support assembly includes multiple support rods, the top ends of which are fixedly connected to the bottom left and right sides of the corresponding connecting plates. The top walls of the multiple bottom connecting plates are provided with support grooves on the left and right sides, and the bottom ends of the multiple support rods are respectively engaged with the corresponding support grooves.

[0009] The above technical solution ensures the vertical support effect of the structure during use by engaging the support rod and the support groove.

A gel composite plate is fixedly connected to the opposite sides of the two polymer waterproof plates. Two pressure-resistant plates are fixedly connected to the opposite sides of the two gel composite plates. Multiple carbon pads are fixedly connected to the opposite sides of the two pressure-resistant plates.

[0012] The above technical solution reduces the impact of water on the structure during pouring by connecting the polymer waterproof board. Then, the connection of the gel composite board achieves the effect of heat insulation, thus achieving the purpose of heat insulation for prefabricated components. Finally, the connection of the pressure-resistant board improves the service life of the weathering board and reduces external pressure damage to the weathering board.

[0013] As a further description of the above technical solution:

[0014] The fixing component includes multiple connecting columns, the top ends of which are respectively fixedly connected to the front and rear sides of the bottom walls of the two bottom fixing plates, and the bottom ends of the connecting columns are fixedly connected to positioning cones.

[0015] The above technical solution enables the connecting column and the positioning cone to penetrate deep into the soil and effectively fix the structure to the ground, thereby improving the stability of the structure.

[0016] As a further description of the above technical solution:

[0017] The connecting mechanism also includes multiple gaskets, the inner walls of which are respectively fixedly connected to the middle of the corresponding positioning bolts.

[0018] The above technical solution reduces the rotational damage to the connecting plate caused by the positioning bolts when the gasket is connected.

[0019] As a further description of the above technical solution:

[0020] Multiple arc-shaped grooves are provided on each adjacent side of the two polymer waterproof membranes, and the multiple arc-shaped grooves are provided at equal intervals.

[0022] As a further description of the above technical solution:

[0023] The weathering mechanism also includes two silicone sealant layers, with the opposite sides of the two silicone sealant layers respectively fixedly connected to the opposite sides of the inner wall of the corresponding weathering plate.

[0024] The above technical solution improves the sealing effect inside the weather-resistant plate and reduces the penetration of water vapor through the silicone sealant layer.

[0025] As a further description of the above technical solution:

[0026] The dimensions of one adjacent end of each of the multiple connecting rods are respectively matched with the internal dimensions of the corresponding mounting sleeve, and the horizontal height of the multiple connecting rods is the same.

[0027] The above technical solution ensures that the size of the adjacent end of the connecting rod matches the internal size of the corresponding mounting sleeve, thereby improving the fit effect during locking installation.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the connection between multiple connecting plates and fixing plates improves the convenience of installation. Then, by rotating the positioning bolts, the fixing plates and connecting plates are locked.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a green building material precast concrete component structure, including multiple fixing rods 1. Each fixing rod 1 has a connecting mechanism 2 on its outer wall, which is used to improve the service life of the concrete component. Each connecting mechanism 2 has a weathering mechanism 3 inside, which is used to increase the weather resistance of the connecting mechanism 2. The connecting mechanism 2 includes multiple connecting plates 201, the inner walls of which are slidably installed on the outer walls of corresponding fixing rods 1, allowing the fixing rods 1 to slide inside the connecting plates 201 and fixing plates 205, initially locking the connecting plates 201 and fixing plates 205. Multiple top connecting... Each connecting plate 201 has a support component 202 at its bottom, which supports the upper and lower connecting plates 201 to form a three-dimensional mechanism. Multiple engaging grooves 203 are formed in the middle of adjacent sides of the multiple connecting plates 201. Multiple positioning bolts 204 are threaded onto the opposite sides of the multiple connecting plates 201. The rotation of the positioning bolts 204 causes the connecting plate 201 to be threadedly connected to the fixing plate 205, further improving the installation effect. The end of the positioning bolt 204 is threadedly connected to the fixing plate 205. A weathering plate 206 is fixedly connected to one side of the fixing plate 205. This connection with the weathering plate 206 avoids the need for an external weathering plate 206 during concrete pouring, ensuring an integrated casting connection and improving the service life of the concrete component. Installation sleeves 207 are fixedly installed on the left and right ends of the multiple fixing rods 1, and connecting rods 208 are fixedly installed on the inner walls of the installation sleeves 207. The connecting rod 208 ensures vertical locking; the support assembly 202 includes multiple support rods 2021, the top ends of which are fixedly connected to the bottom left and right sides of the corresponding connecting plate 201, and work together with the support rods 2021 to provide vertical support. The top walls of the multiple bottom connecting plates 201 are provided with support grooves 2022 on the left and right sides, and the bottom ends of the multiple support rods 2021 are respectively engaged with the corresponding support grooves 2022.

[0040] Specifically, the connecting mechanism 2, which is set on the outer wall of multiple fixed rods 1, improves the service life of concrete components through the coordinated operation of various parts. The weathering mechanism 3 inside enhances the weather resistance of the connecting mechanism 2. The inner wall of multiple connecting plates 201 in the connecting mechanism 2 slides with the outer wall of the corresponding fixed rod 1, so that the fixed rod 1 can slide inside the connecting plate 201 and the fixed plate 205, achieving initial locking of the connecting plate 201 and the fixed plate 205. The support component 202 set at the bottom of the top connecting plate 201 is composed of multiple support rods 2021. Its top end is fixed to the left and right sides of the bottom of the corresponding connecting plate 201 and engages with the support grooves 2022 opened on the left and right sides of the top wall of the bottom connecting plate 201, supporting the upper and lower connecting plates 201 to form a three-dimensional stable structure and ensure the vertical support strength. Multiple locking points are opened in the middle of the adjacent side of the multiple connecting plates 201. The groove 203 facilitates the interlocking and positioning of the fixing plates 205. Multiple positioning bolts 204, threaded on opposite sides, are threaded to the fixing plates 205. By rotating the positioning bolts 204, the connecting plate 201 and the fixing plate 205 are locked together, further improving the stability of the installation. The weathering plate 206, fixedly connected to one side of the fixing plate 205, does not require an additional external weathering plate 206 during concrete pouring. It is directly integrally formed with the concrete component, achieving integrated casting and connection, effectively improving the service life of the concrete component. The mounting sleeves 207, which are fixedly installed on the left and right ends of the multiple fixing rods 1, have connecting rods 208 fixed to their inner walls, further ensuring the vertical locking of the fixing rods 1, enhancing the overall structural stability, and ensuring that the connecting mechanism 2 and the weathering mechanism 3 work together to improve the durability and reliability of the concrete component.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The weathering mechanism 3 includes two polymer waterproof plates 301. The adjacent sides of the two polymer waterproof plates 301 are respectively fixedly connected to the adjacent sides of the inner walls of the two weathering plates 206. Under the connection of the polymer waterproof plates 301, the waterproof protection of the weathering plates 206 to the connecting mechanism 2 during concrete pouring is effectively improved. The two polymer waterproof plates 301 are fixedly connected to gel composite plates 303 on opposite sides. Under the connection of gel composite plates 303, the heat insulation effect inside the concrete component after pouring can be improved. Two compression plates 304 are fixedly connected to opposite sides of the two gel composite plates 303. Under the connection of compression plates 304 and carbon pads 305, the weathering plate 206 can resist external pressure and reduce the damage of external pressure to the inside of the component. Multiple carbon pads 305 are fixedly connected to opposite sides of the two compression plates 304.

[0042] Specifically, two polymer waterproof boards 301 are fixed to adjacent sides of the inner walls of two weathering boards 206, forming a continuous weathering-resistant structural layer during concrete pouring. This effectively blocks external moisture intrusion and enhances the protective capability of the weathering board 206 against the connection mechanism 2, thereby ensuring the connection stability and durability of the concrete component. The gel composite board 303 has excellent thermal insulation properties. After the concrete is poured and formed, it can effectively reduce the exchange of heat between the inside of the component and the outside, maintain stable internal temperature, improve the thermal insulation effect of the concrete component, and prevent thermal expansion caused by temperature changes. Cold shrinkage can damage components. Two compression plates 304 fixedly connected to the opposite side of the gel composite board 303, together with multiple carbon pads 305, form a compression buffer system. The compression plates 304, with their high strength, provide basic compression support for the weathering plate 206, while the carbon pads 305, with their high elasticity and high strength, can effectively buffer external pressure, giving the weathering plate 206 stronger compression resistance. This effectively disperses and absorbs external pressure, reducing the risk of damage to the internal structure of the concrete component from external pressure, and improving the overall compression performance and structural safety of the component.

[0043] Reference Figure 1 , Figure 4 and Figure 5 The fixing component 4 includes multiple connecting columns 401, the top ends of which are fixedly connected to the front and rear sides of the bottom wall of the two bottom fixing plates 205 respectively, and the bottom end of the connecting column 401 is fixedly connected to a positioning cone 402; the connecting mechanism 2 also includes multiple gaskets 209, the inner walls of which are fixedly connected to the middle of the corresponding positioning bolts 204; multiple arc-shaped grooves 302 are opened on the adjacent side of the two polymer waterproof plates 301, and the multiple arc-shaped grooves 302 are all opened at equal intervals;

[0044] Specifically, the connection between multiple connecting columns 401 and positioning cones 402 allows the bottom of the structure to penetrate deep into the soil and be fixed, thereby improving the stability of the structure during use. The connection of multiple gaskets 209 reduces the rotational damage to the connecting plate 201 caused by the positioning bolts 204. The multiple arc-shaped grooves 302 opened on one side of the polymer waterproof board 301 improve the toughness of the polymer waterproof board 301, thereby increasing its strength.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The weathering mechanism 3 also includes two silicone sealant layers 306, with the opposite sides of the two silicone sealant layers 306 respectively fixedly connected to the opposite side of the inner wall of the corresponding weathering plate 206; the size of one adjacent end of the multiple connecting rods 208 is respectively matched with the internal size of the corresponding mounting sleeve 207, and the horizontal height of the multiple connecting rods 208 is the same.

[0046] Specifically, the silicone sealant layer 306 improves the sealing performance of the weathering plate 206 and reduces the intrusion of moisture. By matching the size of the adjacent ends of the connecting rod 208 with the internal size of the corresponding mounting sleeve 207, the adaptability of the connecting rod 208 during installation is improved.

[0047] Working principle: Multiple connecting plates 201 slide against the inner wall of the fixing plate 205 and the outer wall of the fixing rod 1, allowing the fixing rod 1 to initially install the connecting plates 201 and 205. The initial positioning of the installation structure is achieved through the engagement of the locking grooves 203 on adjacent sides of the connecting plates 201 with the fixing plates 205, thus improving installation convenience. Positioning bolts 204 pass through the connecting plates 201 and are threadedly connected to the fixing plates 205. Rotating the positioning bolts 204 tightens the connection between the connecting plates 201 and 205, enhancing connection stability. A weathering plate 206 fixed to one side of the fixing plate 205 directly bonds with the concrete during pouring, forming... The integrated weather-resistant layer avoids the peeling problem caused by thermal expansion and contraction of the external weather-resistant layer, ensuring that the weather-resistant layer and the concrete component are stressed synchronously, thus improving the overall durability. The support component 202 at the bottom of the top connecting plate 201 is fixed to the bottom of the connecting plate 201 by the top of the support rod 2021 and the bottom end is inserted into the support groove 2022 on the top wall of the bottom connecting plate 201, forming a three-dimensional support structure for the upper and lower connecting plates 201, which enhances the vertical stability. The mounting sleeves 207 at the left and right ends of the fixing rod 1 cooperate with the inner wall connecting rod 208 to further lock the vertical connection, ensuring the multi-dimensional stability of the connection mechanism 2, and ultimately improving the service life and product quality of the concrete component.

[0048] Furthermore, during the concrete pouring process, the polymer waterproof board 301 forms a waterproof barrier, effectively preventing moisture from penetrating the connecting mechanism 2 and the interior of the concrete component. This prevents steel corrosion and material deterioration caused by moisture penetration, ensuring the stability of the internal structure of the component. The gel composite board 303 utilizes its excellent thermal insulation properties to reduce heat exchange between the interior of the concrete component and the outside environment, maintaining stable internal temperature and avoiding concrete cracking and performance degradation caused by drastic temperature changes, thus achieving the purpose of thermal insulation. The gel composite board 303, along with two compression plates 304 fixed to the opposite side, and multiple carbon pads 305, constitute a compression protection structure. The compression plates 304, with their high strength, provide basic compression support for the weathering plate 206. The carbon pads 305, relying on their high elasticity and high strength, effectively buffer and disperse stress under external pressure. The synergistic effect of the two makes the weathering plate 206 have stronger compression resistance, reducing the risk of damage to the interior of the concrete component caused by external pressure, extending the service life of the weathering plate 206 and the entire concrete component, and improving the component's resistance to external pressure.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
