Description

Technical Field

[0001] This utility model belongs to the field of composite wall formwork technology, and in particular relates to a lightweight bamboo-steel composite wall formwork keel system. Background Technology

[0002] With increasingly stringent environmental protection requirements in the construction industry, energy conservation and emission reduction have become emerging research topics. People are particularly concerned about carbon emissions from the construction industry, especially the use of materials like cement and steel, prompting the search for bio-based alternatives. Bamboo's rapid growth and high strength make it a viable option for a quick transition to biomass construction. Bamboo-steel construction, which involves processing and pressing bamboo, significantly enhances its strength and toughness. Bamboo's lightweight and high strength make it an excellent material for building structures, and its bundled and round forms offer strong torsional stability, facilitating the promotion of bamboo-steel structures. The composite wall formwork keel system, with sound-absorbing cotton, fireproof boards, and decorative panels on the outside, creates a composite wall formwork structure with superior overall performance. To further improve the stability of the overall composite wall formwork structure, a lightweight bamboo-steel composite wall formwork keel system is needed. This system reduces the weight of the composite wall formwork keel by using bamboo-steel materials, making the frame lighter, and connects the various panels of the composite wall formwork into a whole through connecting components, thereby improving the overall structural stability of the composite wall formwork. Utility Model Content

Furthermore, by connecting components, the various panels of the composite wall formwork are connected into a whole, thereby improving the overall structural stability of the composite wall formwork and solving the technical problems mentioned in the background art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a lightweight bamboo-steel composite wall formwork keel system, which includes bamboo-steel uprights: the surface of the bamboo-steel uprights is provided with clamping blocks and bamboo-steel strips, and a bolt rod is installed through the clamping blocks and bamboo-steel strips. The surface of the bolt rod is threaded with a nut block. The surface of the bamboo-steel strips is fixedly connected with bamboo-steel crossbars by bolts. The inner cavity of the bamboo-steel uprights is provided with fine glass wool board. The outer side of the fine glass wool board is sequentially fixedly connected with a sound-absorbing board and a paper-faced gypsum board. The surface of the sound-absorbing board and the paper-faced gypsum board are both provided with rod grooves. The surface of the bamboo-steel strips is fixedly connected with anchor rods. The space between the anchor rods and the inner wall of the rod grooves is filled with a structural adhesive layer.

[0005] Preferably, a washer is fitted on the surface of the bolt rod, and the washer is an elastic washer.

[0006] Preferably, a connecting block is bonded together between the bamboo steel strip and the bamboo steel crossbar.

[0007] Preferably, the surface of the anchor rod is integrally formed with a plurality of support rods.

[0008] Preferably, both the clamping block and the bamboo steel strip are attached to the bamboo steel upright.

[0009] The beneficial effects of this utility model are:

[0010] This utility model uses a combination of clamping blocks, bamboo steel strips, bolts, and nuts to fix bamboo steel crossbars to the surface of bamboo steel uprights. The sound-absorbing panels and paper-faced gypsum board are fixed to the bamboo steel strips through anchor rods and structural adhesive layers. This achieves the goal of reducing the weight of the composite wall formwork keel by using bamboo steel materials, making the frame lightweight, and connecting the various panels of the composite wall formwork into a whole through connecting components, thereby improving the overall structural stability of the composite wall formwork.

[0011] 2.

[0018] In the following description, embodiments of the lightweight bamboo-steel composite wall formwork keel system of this utility model will be described with reference to the accompanying drawings. Example 1

[0019] Figure 1-3This invention illustrates a lightweight bamboo-steel composite wall formwork keel system according to an embodiment of the present invention. It includes a bamboo-steel upright 1. The surface of the bamboo-steel upright 1 is provided with clamping blocks 2 and bamboo-steel strips 3. A bolt rod 4 is threaded through the clamping blocks 2 and bamboo-steel strips 3. A nut block 5 is threaded onto the surface of the bolt rod 4. A washer 6, which is an elastic washer, is fitted onto the surface of the bolt rod 4. The washer 6 increases the friction on the surface of the nut block 5, preventing the nut block 5 from loosening and coming off the surface of the bolt rod 4 due to external vibration, thereby improving the stability of the connection between the bolt rod 4 and the nut block 5. A bamboo-steel horizontal bar is fixedly connected to the surface of the bamboo-steel strips 3 by bolts. A connecting block 8 is bonded together between the pole 7, the bamboo steel strip 3, and the bamboo steel crossbar 7. The connection between the bamboo steel crossbar 7 and the bamboo steel strip 3 is reinforced by the connecting block 8, which improves the stability of the connection and avoids the loosening and separation of the two due to the small contact area. The inner cavity of the bamboo steel upright 1 is provided with a fine glass wool board 9. The outer side of the fine glass wool board 9 is fixedly connected with a sound-absorbing board 10 and a paper-faced gypsum board 11. The surfaces of the sound-absorbing board 10 and the paper-faced gypsum board 11 are both provided with a rod groove 12. An anchor rod 13 is fixedly connected to the surface of the bamboo steel strip 3. The space between the anchor rod 13 and the inner wall of the rod groove 12 is filled with a structural adhesive layer 14. Example 2

It includes a bamboo-steel upright 1; the surface of the bamboo-steel upright 1 is provided with clamping blocks 2 and bamboo-steel strips 3, and a bolt rod 4 is threaded through and installed between the clamping blocks 2 and the bamboo-steel strips 3; a nut block 5 is threaded onto the surface of the bolt rod 4; bamboo-steel crossbars 7 are bolted to the surface of the bamboo-steel strips 3; a fine glass wool board 9 is provided inside the bamboo-steel upright 1; and a sound-absorbing board 10 is sequentially fixed to the outer side of the fine glass wool board 9. The paper-faced gypsum board 11, the sound-absorbing board 10, and the paper-faced gypsum board 11 are all provided with rod grooves 12. The surface of the bamboo steel strip 3 is fixedly connected with anchor rods 13. The anchor rods 13 and the inner wall of the rod grooves 12 are filled with structural adhesive layer 14. The surface of the anchor rods 13 is integrally formed with several support rods 15.

The clamping block 2 and the bamboo steel strip 3 are both attached to the bamboo steel upright 1.

[0021] Working principle: When using this utility model, the user fixes the bamboo steel upright 1 to the ground, then places the fine glass wool board 9 on the surface of the bamboo steel upright 1. Subsequently, through the cooperation of the clamping block 2, bamboo steel strip 3, bolt rod 4, and nut block 5, the bamboo steel crossbar 7 is fixed to the surface of the bamboo steel upright 1, so that the bamboo steel crossbar 7 connects the bamboo steel upright 1 into a whole and limits the position of the fine glass wool board 9. Then, the sound-absorbing board 10 and the paper-faced gypsum board 11 are cut to form the rod groove 12, and then the rod groove 12 is cleaned of dust. After processing and injecting the structural adhesive layer 14, the sound-absorbing board 10 and the paper-faced gypsum board 11 are then fixed to the surface of the bamboo steel crossbar 7 in sequence, so that the anchor rod 13 is inserted into the inner cavity of the rod groove 12. At this time, the sound-absorbing board 10 and the paper-faced gypsum board 11 are fixed to the bamboo steel strip 3 by the anchor rod 13 and the structural adhesive layer 14. This achieves the reduction of the weight of the composite wall formwork keel by the application of bamboo steel material, making the skeleton lightweight. Furthermore, the composite wall formwork panels are connected into a whole by connecting components, thereby improving the overall stability of the composite wall formwork structure.
