Description

Technical Field

[0001] This utility model relates to the field of precast concrete technology, specifically to a precast concrete component. Background Technology

[0002] With the continuous development of the construction industry, the focus has shifted from traditional cast-in-place reinforced concrete structures to precast concrete components. Traditional cast-in-place reinforced concrete construction involves extensive on-site fabrication, wet work, and numerous intermediate steps such as formwork and scaffolding, resulting in resource waste and environmental pollution. Precast concrete, on the other hand, is cleaner and less wasteful. However, existing precast concrete components lack protective structures, and their connection structures are relatively simple, failing to provide rapid connection and positioning functionality. Therefore, a new type of precast concrete component has been designed to address these issues.

[0003] A precast concrete component, authorized by announcement number CN217105500U, includes an inner concrete slab and an outer concrete slab. A filling cavity is formed between the inner and outer concrete slabs. The filling cavity is filled with inorganic thermal insulation filler and organic thermal insulation filler located within the space enclosed by the inorganic thermal insulation filler. Multiple connecting bars are also connected between the inner and outer concrete slabs and simultaneously inserted into the filling cavity. The connecting bars are fixedly connected or integrally connected to the steel mesh within both the inner and outer concrete slabs. By placing the organic thermal insulation filler within the space enclosed by the inorganic thermal insulation filler, corrosion of the organic thermal insulation filler is effectively prevented. Simultaneously, the inorganic thermal insulation filler also has a certain barrier effect, preventing flames or high-temperature fumes from penetrating into the precast concrete component and causing combustion, resulting in relatively high safety.

[0004] Based on existing solutions and actual production and processing, current precast concrete components still have some problems: First, existing precast concrete components do not have fire resistance, causing them to crack downwards at high temperatures; second, their internal structure is simple, resulting in low load-bearing capacity and poor support; and finally, some precast concrete components have simple connection structures, which are prone to instability. Therefore, this utility model provides a precast concrete component to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a precast concrete component to solve the problems mentioned in the background art, such as the lack of fire resistance of existing precast concrete components, which cause them to fracture downwards under high temperature conditions; the simple internal structure with low load-bearing capacity and poor support; and the simple connection structure of some precast concrete components, which is prone to instability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a precast concrete component, comprising: a precast concrete component body for installation, and a first steel truss fixedly installed inside the front end of the precast concrete component body;

[0007] It also includes: a fireproof mechanism is provided on the front side of the first steel truss, wherein the fireproof mechanism includes a heat insulation layer, a second steel truss and a fireproof coating, the front end of the heat insulation layer is provided with a second steel truss, and the front end of the second steel truss is provided with a fireproof coating.

[0008] The locking block has an internal locking mechanism, which includes a sliding block, a spring, and a connecting rib. The sliding block and the spring are located at the middle of the front and rear ends of the locking block, with the spring located to the left of the sliding block. A connecting rib is located at the lower end of the locking block.

[0009] Preferably, the first steel truss is symmetrically arranged about the centerline of the precast concrete component body, and the front end of the first steel truss is in contact with the heat insulation layer, the front end of the heat insulation layer is in contact with the second steel truss, and the front end of the second steel truss is in contact with the fireproof coating.

[0010] Preferably, the precast concrete component body has holes spaced at equal intervals in the middle, and a third steel truss is symmetrically arranged on the left and right sides of the holes.

[0011] Preferably, the left side of the precast concrete component body is provided with fixed connecting blocks at equal intervals, and the bottom center of the fixed connecting block is provided with a connecting hole, and the inner wall of the fixed connecting block is provided with a groove, and the cross-section of the groove is set in an arc shape.

[0012] Preferably, a locking block is provided at the right end of the precast concrete component body, and the cross-section of the locking block is cross-shaped, and the fixing connection block is connected to the locking block by a locking method.

[0013] Preferably, the sliding block forms a sliding structure inside the card block, and the left side of the sliding block is in contact with the spring, and the right end of the sliding block is in a semi-circular state.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the precast concrete component is easy to fireproof, easy to increase the load-bearing capacity of the precast concrete component, and easy to strengthen the stable connection of the precast concrete component.

[0015] 1. The structure is equipped with a heat insulation layer, a second steel truss, and a fireproof coating. To prevent the precast concrete components from cracking due to high temperatures, a heat insulation layer is applied to the front side of the first steel truss to achieve a certain heat insulation effect. At the same time, to enhance stability, a second steel truss is set in front of the heat insulation layer. The fireproof coating is applied to the front end of the second steel truss to provide a certain fireproof effect, which facilitates the fireproofing treatment of the precast concrete components.

[0016] 2. A first steel truss, a manhole, and a third steel truss are provided. In order to enhance the stability of the precast concrete component, a first steel truss and a second steel truss are respectively set at the front and rear ends of the precast concrete component to enhance the overall stability of the front and rear ends. At the same time, a manhole is set in the middle of the precast concrete component, and the third steel truss is set on the left and right sides of the manhole to enhance the support force in the middle of the precast concrete component, ensuring the overall structure of the precast concrete component is solid and facilitating the addition of load-bearing support to the precast concrete component.

[0017] 3. Equipped with a fixed connecting block, a locking block, and a spring, when a stable connection of precast concrete components is required, the locking block of one section of the precast concrete component body is first inserted into the fixed connecting block at the left end of another precast concrete component body. The locking block then drives the sliding block to continuously move downwards along the path of the fixed connecting block, causing the sliding block in the locking block to be squeezed and slide inwards. When the locking block drives the sliding block to be parallel to the groove, the sliding block is locked into the inside of the groove by the spring force, thus stably connecting the fixed connecting block and the locking block. At the same time, the locking block also drives the connecting rib to be inserted into the connection hole at the bottom end of the fixed connecting block. The connecting rib at the bottom end of the locking block can be twisted and knotted to strengthen the stable connection between the locking block and the fixed connecting block, which facilitates the stable connection of precast concrete components.

[0026] When fireproofing precast concrete components, for example, by attaching... Figure 2 Appendix Figure 3 and attached Figure 4As shown, the first steel truss 2 is symmetrically arranged about the centerline of the precast concrete component body 1. The front end of the first steel truss 2 is in contact with the heat insulation layer 3, the front end of the heat insulation layer 3 is in contact with the second steel truss 4, and the front end of the second steel truss 4 is in contact with the fireproof coating 5. Holes 6 are evenly spaced in the middle of the precast concrete component body 1, and third steel trusses 7 are symmetrically arranged on the left and right sides of the holes 6. To prevent the precast concrete component from being affected by high-temperature burning and cracking, which would affect the service life of the precast concrete component, it is necessary to strengthen the precast concrete component. The first steel truss 2 and the second steel truss 4 are respectively set at the front and rear ends of the precast concrete component body 1 to strengthen the overall front and rear stability. Then, a hole 6 is set in the middle of the precast concrete component body 1, and the third steel truss 7 is set on the left and right sides of the hole 6 to strengthen the support force in the middle of the precast concrete component body 1 and ensure the overall structure of the precast concrete component body 1 is firm. In order to make it fireproof, when the first steel truss 2 and the second steel truss 4 are set inside the front and rear ends of the precast concrete component body 1, the heat insulation layer 3 is applied to the front side of the first steel truss 2 to achieve a certain heat insulation effect. At the same time, in order to enhance stability, the second steel truss 4 is set in front of the heat insulation layer 3, and the fireproof coating 5 is applied to the front end of the second steel truss 4 to play a certain fireproof role. In this way, the fireproof and heat insulation effect can be achieved, thereby strengthening the firmness of the precast concrete component.

A groove 10 is provided on the inner wall of each fixed connecting block 8, with an arc-shaped cross-section. A locking block 11 is provided on the right end of the precast concrete component body 1, with a cross-shaped cross-section. The fixed connecting blocks 8 and locking blocks 11 are connected by a locking mechanism. A sliding block 12 forms a sliding structure inside the locking block 11. The left side of the sliding block 12 is in contact with the spring 13, and the right end of the sliding block 12 is semi-circular. To ensure a stable connection between the precast concrete component bodies 1 and the precast concrete component body 1, the precast concrete component body 1 must first be... The locking block 11 of one segment is inserted into the fixed connecting block 8 at the left end of another precast concrete component body 1. The locking block 11 drives the sliding block 12 to continuously move downward along the path of the fixed connecting block 8, so that the sliding block 12 in the locking block 11 is squeezed and slides into the locking block 11. When the locking block 11 drives the sliding block 12 to be parallel with the groove 10, the sliding block 12 is engaged into the inside of the groove 10 by the elastic force of the spring 13, and finally the fixed connecting block 8 and the locking block 11 are stably connected. At the same time, the locking block 11 also drives the connecting rib 14 to be inserted into the bottom connecting hole 9 of the fixed connecting block 8. The connecting rib 14 at the lower end of the locking block 11 can be twisted and knotted to strengthen the stable connection between the locking block 11 and the fixed connecting block 8, thereby realizing the fixed splicing of the precast concrete component.
