Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a formwork-free reinforcement structure for reinforcing old concrete foundations. Background Technology

[0002] With the acceleration of urbanization, a large number of old buildings are facing problems such as functional aging and structural performance degradation. Among them, a large number of old building structures with reinforced concrete strip foundations require further reinforcement. For the reinforcement of old concrete strip foundations, the on-site formwork method is often used. The formwork is erected on the side of the old concrete foundation to be reinforced first, and a frame is erected on the outside of the formwork to support it. This will occupy a lot of space around the old concrete foundation, and construction cannot be carried out in small spaces. Moreover, a lot of construction waste will be generated during the construction process, which is difficult to operate and does not meet environmental protection requirements. Therefore, we propose a formwork-free reinforcement structure for reinforcing old concrete foundations to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a formwork-free reinforcement structure for reinforcing old concrete foundations, which solves the problems of large space occupation and construction waste generated when using formwork during the reinforcement of old concrete foundations.

[0004] This utility model is achieved through the following solution: a formwork-free reinforcement structure for reinforcing old concrete foundations, comprising:

[0005] Precast slab assembly;

[0006] The support rod is fixedly connected to one side of the old concrete foundation to be reinforced. It is used to connect and support the precast slab assembly so that a pouring space is formed between the precast slab assembly and the side of the old concrete foundation to be reinforced, and a pouring port for pouring concrete is formed at the top of the pouring space.

[0007] The cast-in-place concrete body is formed by pouring concrete into the pouring space through the pouring port, and the formed cast-in-place concrete body encloses the support rod and forms a whole with the old concrete foundation and the precast formwork assembly to share the load.

[0008] A further improvement of this utility model for a formwork-free reinforcement structure for reinforcing old concrete foundations is that it also includes a steel mesh set in the pouring space, wherein the steel mesh is anchored in the cast-in-place concrete.

[0009] A further improvement of this utility model for a formwork-free reinforcement structure for reinforcing old concrete foundations is that it also includes a connector fixed to one side of the old concrete foundation to be reinforced, used to connect and support the steel mesh before pouring concrete, and the connector is anchored in the cast-in-place concrete.

[0010] A further improvement of this utility model for a formwork-free reinforcement structure for reinforcing old concrete foundations is that the connector includes multiple connecting ribs arranged in an array.

[0011] A further improvement of this utility model for a formwork-free reinforcement structure for reinforcing old concrete foundations is that the precast slab assembly includes an outer slab and two side slabs. The outer slab is fixedly connected to a support rod, and the two side slabs are respectively fixed to both sides of the outer slab, and both side slabs are fixed to the old concrete foundation.

[0012] A further improvement of this utility model for a formwork-free reinforcement structure for reinforcing old concrete foundations is that it also includes a limiting member set at the lower part of the precast slab assembly to prevent the lower part of the precast slab assembly from shifting during concrete pouring.

[0013] A further improvement of this utility model for a formwork-free reinforcement structure for reinforcing old concrete foundations is that the limiting member includes multiple temporary plates, which are arranged around the lower periphery of the precast slab assembly, with the lower part of the multiple temporary plates inserted into the nearby soil and the upper part abutting against the precast slab assembly.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention creates a pouring space for concrete by setting up a precast slab assembly between the precast slab assembly and the old concrete foundation. Before pouring the concrete, support rods are used to support and fix the precast slab assembly. After the concrete is poured, the cast-in-place concrete body will wrap around the support rods and anchor together with the old concrete foundation and the precast formwork assembly, forming a whole that shares the load. This increases the cross-section of the old concrete foundation to achieve a reinforcement effect. The support rods can strengthen the connection between the old concrete foundation, the cast-in-place concrete body, and the precast slab assembly. The overall construction area is small, and the formwork-free construction can significantly reduce the generation of waste during the construction process, making it environmentally friendly and energy-saving.

[0020] To address the problems of large space requirements and construction waste associated with using formwork in reinforcing old concrete foundations, this invention provides a formwork-free reinforcement structure for old concrete foundations. The following detailed description, in conjunction with accompanying drawings, illustrates this formwork-free reinforcement structure for old concrete foundations.

[0021] See Figures 1-3 As shown, a formwork-free reinforcement structure for reinforcing old concrete foundations includes:

[0022] Precast slab assembly;

[0023] Support rod 5 is fixedly connected to the side of the old concrete foundation 8 to be reinforced, and is used to connect and support the precast slab assembly so that a pouring space 10 is formed between the precast slab assembly and the side of the old concrete foundation 8 to be reinforced, and a pouring port 9 for pouring concrete is formed on the upper part of the pouring space 10.

[0024] The cast-in-place concrete body is formed by pouring concrete into the pouring space 10 from the pouring port 9, and the cast-in-place concrete body formed therein wraps the support rod 5 and forms a whole that shares the load with the old concrete foundation 8 and the precast formwork assembly.

[0025] By setting up a pouring space 10 between the precast slab assembly and the old concrete foundation 8, a concrete pouring space is formed. Before pouring the concrete, the precast slab assembly is supported and fixed by support rods 5. After the concrete is poured, the cast-in-place concrete body will wrap around the support rods 5 and anchor together with the old concrete foundation 8 and the precast formwork assembly, forming a whole that shares the load. This increases the cross-section of the old concrete foundation 8 to achieve a reinforcement effect. The support rods 5 can strengthen the connection between the old concrete foundation 8, the cast-in-place concrete body, and the precast slab assembly. The overall construction area is small, and the formwork-free construction can significantly reduce the generation of waste during the construction process, which is environmentally friendly and energy-saving.

[0026] Among them, see Figure 1 As shown, it also includes a steel mesh 1 set in the pouring space 10, which is anchored in the cast-in-place concrete.

[0027] By using the aforementioned steel mesh 1, the cast-in-place concrete structure can be used as a skeleton to enhance its strength, thereby better reinforcing the old concrete foundation 8.

[0028] Among them, see Figure 1 As shown, it also includes a connector fixed to one side of the old concrete foundation 8 to be reinforced, used to connect and support the steel mesh 1 before pouring concrete, and the connector is anchored in the cast-in-place concrete.

[0029] By adopting the above design, the steel mesh 1 is supported and fixed in the pouring space 10 before the concrete is poured. After the concrete is poured, it can be anchored in the middle of the cast-in-place concrete body to avoid the steel mesh 1 becoming marginalized, thereby ensuring the overall strength of the cast-in-place concrete body is balanced.

[0030] Among them, see Figure 1-3 As shown, the connector includes multiple connecting ribs 6, and the multiple connecting ribs 6 are arranged in an array.

[0031] By adopting the above design, the arrayed connecting bars 6 can firmly fix and support the suspended steel mesh 1, providing multi-directional support. After the concrete is poured, they are anchored together in the cast-in-place concrete body, which can greatly improve the overall strength of the cast-in-place concrete body. At the same time, it also improves the tensile force between the old concrete foundation 8, the precast slab assembly and the cast-in-place concrete body, making the three more firmly anchored, thus resulting in a good reinforcement effect.

[0032] Among them, see Figure 2 As shown, the precast slab assembly includes an outer slab 2 and two side slabs 4. The outer slab 2 is fixedly connected to the support rod 5. The two side slabs 4 are respectively fixed to both sides of the outer slab 2, and both side slabs 4 are fixed to the old concrete foundation 8 by bolts.

[0033] Furthermore, both the outer panel 2 and the side panels 4 are made of high-performance concrete and are prefabricated in advance, with dimensions that can be customized according to specific construction requirements; the two side panels 4 are also fixedly connected to the outer panel 2 by bolts.

[0034] By adopting the above design, the outer panel 2, side panel 4, old concrete foundation 8 and the surrounding ground are used to form a pouring space 10. The outer panel 2 and side panel 4 are fixed on the inside, which will not occupy a lot of surrounding space. Moreover, the outer panel 2 and side panel 4 will be anchored together with the cast-in-place concrete body to form a load-bearing whole, which is used to expand the cross section and reinforce the old concrete foundation 8. This will strengthen the wall 7 built on the old concrete foundation 8, without repeated disassembly and assembly, greatly reducing the generation of construction waste and meeting environmental protection requirements.

[0035] Among them, see Figure 1 and 2 As shown, it also includes a limiting member set at the lower part of the precast slab assembly to prevent the lower part of the precast slab assembly from shifting during concrete pouring;

[0036] The limiting component includes multiple temporary plates 3, which are arranged around the lower periphery of the precast slab assembly, with the lower part of the multiple temporary plates 3 inserted into the nearby soil and the upper part abutting against the precast slab assembly.

[0037] By adopting the above design, multiple temporary panels 3 are used to surround the lower part of the outer panel 2 and the side panel 4, which can achieve a supporting effect and prevent displacement during concrete pouring, thereby affecting the forming effect of the cast-in-place concrete body.
