Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, and in particular to a large-volume concrete construction component. Background Technology

[0002] Massive concrete structures are frequently used in construction, such as foundations for high-rise buildings, large equipment, and hydraulic dams. Their main characteristic is their large volume, with the smallest cross-section having a dimension of at least 1 meter in any direction. Due to the relatively small surface area coefficient of mass-produced concrete structures, the heat of hydration of cement is released more concentratedly, leading to rapid internal heating. This can cause temperature cracks in the concrete structure when there is a significant temperature difference between the inside and outside of the concrete, affecting structural safety and normal use.

[0003] Therefore, during the construction of large-volume concrete, it is usually necessary to use cooling water in a timely manner to reduce the temperature difference between the inside and outside of the concrete and prevent temperature cracks from forming. Furthermore, in order to cool the interior of the large-volume concrete structure in a timely manner, channels need to be pre-installed inside the structure for injecting cooling water. However, how to design these cooling water injection channels within the large-volume concrete structure, and how to pre-install them in a way that avoids both insufficient or improperly designed channels leading to limited cooling effect and damage to the concrete structure's strength, are all technical problems that urgently need to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a large-volume concrete construction component that solves the above-mentioned technical problems.

[0005] Therefore, the technical solution of this utility model is as follows:

[0006] A large-volume concrete construction component includes a concrete reinforcing steel skeleton, an internal cooling water pipe assembly, and an external cooling water pipe assembly. The concrete reinforcing steel skeleton is formed by binding several transverse and longitudinal reinforcing bars and is adapted to the shape and size of the concrete structure to be poured. The internal cooling water pipe assembly consists of multiple rows of pre-embedded rigid pipes spaced apart along the longitudinal direction of the concrete reinforcing steel skeleton, with each row consisting of multiple pre-embedded rigid pipes spaced apart along the transverse direction of the concrete reinforcing steel skeleton. The external cooling water pipe assembly includes multiple external flexible hoses, the number of which corresponds to the number of pre-embedded rigid pipes, for connection to the ends of two pre-embedded rigid pipes respectively. A first connecting thread is fixedly connected to both ends of each pre-embedded rigid pipe, and a second connecting thread is fixedly connected to both ends of each external flexible hose. The two are detachably connected by a connecting sleeve, allowing multiple pre-embedded rigid pipes to be connected through multiple external flexible hoses to form one or more cooling water pipe channels.

[0007] Furthermore, in the multi-row pre-embedded rigid pipe group, the distance between two adjacent rows of pre-embedded rigid pipe groups is 0.5m to 1.5m; in each row of pre-embedded rigid pipe group, the distance between two adjacent pre-embedded rigid pipes is 0.5m to 1.5m; the diameter of each pre-embedded rigid pipe (2) is 2cm to 4cm and the length is 1m to 10m.

[0008] Furthermore, each pre-embedded rigid pipe has the same direction of penetration on the concrete reinforcing steel cage, and is penetrated in the direction of transverse thickness ≤10m on the concrete reinforcing steel cage.

[0009] Furthermore, the pre-embedded rigid pipe is made of PVC rigid pipe, and the external flexible pipe is made of PVC flexible pipe.

[0010] Furthermore, water-stop sealing rings are provided at the connection between the first connecting thread and the connecting sleeve, and at the connection between the second connecting thread and the connecting sleeve.

[0011] Furthermore, the large-volume concrete construction component also includes multiple formwork panels, multiple tie bolts, and multiple formwork supports. The multiple formwork panels are adapted to the shape and size of the concrete structure to be poured, so that the multiple formwork panels are connected in sequence and surround the outer wall of the concrete reinforcement skeleton to form a closed pouring space. The formwork panels are provided with through holes, so that the two ends of the pre-embedded rigid pipes can pass through the through holes to the outside of the formwork panels. The number of tie bolts is the same as the number of pre-embedded rigid pipes, and the outer diameter is adapted to the inner diameter of the pre-embedded rigid pipes, so that the multiple tie bolts are respectively inserted into each pre-embedded rigid pipe and initially form supports.

[0012] Furthermore, the large-volume concrete construction component also includes multiple formwork supports, which are diagonally or vertically supported on the outer wall of each formwork, with the other end fixed to the ground; at least two formwork supports are spaced apart on the outer wall of each formwork.

[0013] Compared with existing technologies, this large-volume concrete construction component is suitable for large-volume concrete pouring construction, solving the construction defects caused by temperature cracks due to the inability to effectively reduce the temperature difference between the inside and outside of the concrete caused by the excessive volume of current concrete structures. In addition, the use of large-volume concrete construction components for concrete pouring construction also has the advantages of convenient installation, adaptability to different structural sizes, no need for additional measures, and most components can be reused repeatedly.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention.

[0023] See Figures 1-8 The large-volume concrete construction component includes a concrete steel reinforcement skeleton 1, an inner cooling water pipe assembly, and an outer cooling water pipe assembly.

[0024] The concrete reinforcement cage 1 is formed by binding together several transverse and longitudinal steel bars, and is adapted to the shape and size of the concrete structure to be poured.

[0025] See Figure 3 and Figure 4 The internal cooling water pipe assembly consists of multiple rows of pre-embedded rigid pipes spaced apart along the longitudinal direction of the concrete reinforcing steel skeleton 1. Each row of pre-embedded rigid pipes consists of multiple pre-embedded rigid pipes 2 spaced apart along the transverse direction of the concrete reinforcing steel skeleton 1. Preferably, each pre-embedded rigid pipe 2 has the same penetration direction on the concrete reinforcing steel skeleton 1.

[0026] In this embodiment, in the multi-row pre-embedded rigid pipe group, the distance between two adjacent rows of pre-embedded rigid pipe groups is 0.8m; in each row of pre-embedded rigid pipe groups, the distance between two adjacent pre-embedded rigid pipes 2 is 1.2m; since the length of the pre-embedded rigid pipe 2 should not be too long, each pre-embedded rigid pipe 2 is installed on the concrete reinforcing steel skeleton 1 in a direction with a transverse thickness of 7.6m, and the length of the pre-embedded rigid pipe 2 is set to be greater than the transverse thickness of the concrete reinforcing steel skeleton 1 by 20cm; the pre-embedded rigid pipe 2 is specifically a PVC rigid pipe with a diameter of 2cm and a length of 8m.

[0027] The external cooling water pipe assembly includes multiple external flexible hoses 7, the number of which is adapted to the number of pre-embedded rigid pipes 2, so that the pre-embedded rigid pipes 2 can form a connected pipeline by connecting the pipe ends of two pre-embedded rigid pipes 2; the external flexible hoses 7 are specifically PVC flexible hoses, and their length is adapted to the distance between the pipe ends of the two pre-embedded rigid pipes 2 used to connect them.

[0028] See Figures 5-8 To facilitate the connection between the pre-embedded rigid pipe 2 and the external flexible pipe 7, a first connecting thread 2-1 is fixedly connected to both ends of each pre-embedded rigid pipe 2, and a second connecting thread 7-1 is fixedly connected to both ends of each external flexible pipe 7, and both are male threads; the second connecting thread 7-1 is also equipped with a connecting sleeve 8, and the two ends of the connecting sleeve 8 are respectively provided with connecting threads that can cooperate with the first connecting thread 2-1 and the second connecting thread 7-1, specifically two female threads, so that the first connecting thread 2-1 and the second connecting thread 7-1 can be detachably connected through the connecting sleeve 8.

[0029] As a preferred technical solution of this embodiment, a water-stop sealing ring is provided at the connection between the first connecting thread 2-1 and the connecting sleeve 8, and at the connection between the second connecting thread 7-1 and the connecting sleeve 8.

[0030] In practical applications, depending on the size of the concrete structure 6, the cooling water pipe channel formed by connecting multiple external flexible hoses 7 and multiple pre-embedded PVC pipes 2 can be one or more, that is, forming a cooling water pipe channel that runs through the concrete structure 6, or multiple cooling water pipe channels that are arranged in parallel and jointly run through the concrete structure 6.

[0031] See Figure 1 The large-volume concrete construction component also includes multiple formwork panels 3, multiple tie bolts 4, and multiple formwork supports 5.

[0032] Multiple formwork panels 3 are adapted to the shape and size of the concrete structure 6 to be poured. Based on the concrete reinforcing cage 1, multiple formwork panels 3 are connected in sequence and surrounded on the outer side wall of the concrete reinforcing cage 1 to form a closed pouring space. Through holes are opened on the formwork panels 3 to cooperate with the pre-embedded rigid pipes 2 fixed on the concrete reinforcing cage 1, so that when the formwork panels 3 are erected on the outside of the concrete reinforcing cage 1, both ends of each pre-embedded rigid pipe 2 pass through the through holes opened on the formwork panels 3 to the outside of the formwork panels 3.

[0033] Multiple template supports 5 are respectively diagonally or vertically supported on the outer wall of each template 3, and their other ends are fixed to the ground to strengthen and fix the setting position of the template 3; wherein, at least two template supports 5 are provided at intervals on the outer wall of each template 3.

[0034] The number of tie bolts 4 is the same as the number of pre-embedded rigid pipes 2, and the outer diameter is adapted to the inner diameter of the pre-embedded rigid pipes 2, so that multiple tie bolts 4 are respectively inserted into each pre-embedded rigid pipe 2. This can not only be used to fix the template 3 by tie bolts 4, but also form a rigid support during concrete pouring by inserting tie bolts 4 into pre-embedded rigid pipes 2, so as to avoid damage to the hollow pre-embedded rigid pipes 2 caused by impact during pouring.

[0035] The specific implementation steps for constructing the concrete structure 6 using this large-volume concrete construction component are described below.

[0036] S1. According to the size and shape of the concrete structure 6 to be poured, multiple transverse and longitudinal steel bars are used to tie the large-volume concrete steel reinforcement cage 1; then multiple rows of pre-embedded rigid pipe groups are arranged along the interval of the steel reinforcement cage 1, and multiple pre-embedded rigid pipes 2 are arranged in each row at intervals; each pre-embedded rigid pipe 2 is tied and fixed to the transverse steel bars located on the adjacent side by multiple steel wires, and both ends of each pre-embedded rigid pipe 2 extend to the outside of the steel reinforcement cage 1.

[0037] S2. Multiple templates 3 are erected on the outside of the concrete reinforcing cage 1, and they are arranged in sequence to surround the outside of the concrete reinforcing cage 1. The two ends of each pre-embedded rigid pipe 2 tied to the concrete reinforcing cage 1 are passed through the through holes opened on the template 3 to the outside of the template 3 and sealed. After the template 3 is installed, tie bolts 4 are inserted into each pre-embedded rigid pipe 2 to fix the template 3 in opposite directions. Then, template supports 5 are set on each template 3 to ensure that the pouring space structure formed by multiple templates 3 is stable.

[0038] S3. Pour concrete and allow it to cure and solidify to form a concrete structure 6;

[0039] S4. After the concrete structure 6 has cured, remove the formwork 3 and pull out the tie bolts 4, and use the pre-embedded rigid pipes 2 to form multiple hollow channels in the concrete structure 6.

[0040] S5. Fit the connecting sleeve 8 onto the pre-embedded rigid pipe 2 and connect the pre-embedded rigid pipe 2 through the external hose 7, so as to form one or more cooling water pipe channels by connecting multiple external hoses 7 and multiple pre-embedded rigid pipes 2.

[0041] S6. Connect the two ends of each cooling water pipe channel formed in step S5 to the inlet and outlet of an external cooling water circulation device, respectively, so as to cool the concrete structure 6 by circulating cooling water.

[0042] S7. After the concrete structure 6 has cooled to the required temperature, remove the external hose 7 and the connecting sleeve 8 so that it can be recycled to the next large volume of concrete for continued use. Using the grouting method, inject mortar into the cavity of the pre-embedded rigid pipe 2 in the cooled concrete structure 6 to fill the cavity, and cut off the part of the pre-embedded rigid pipe 2 located on the outside of the concrete structure 6 as needed.
