Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a deformation joint device for industrial plant floors. Background Technology

[0002] Due to factors such as temperature changes, uneven settlement, and earthquakes, additional stress will be generated inside the building structure. This stress often causes the building to deform or even crack and be destroyed. Expansion joints are structural joints reserved to address this situation. They are usually set at appropriate locations in the building, vertical joints that separate the building's walls, floors, roof, and other components from the foundation upwards, dividing the building into several separate parts that can deform independently. These vertically separated joints are called expansion joints.

[0003] The processing and installation of expansion joint templates for traditional industrial plant floors are complex. Furthermore, because expansion joint templates are prone to deformation, the installation accuracy of expansion joints is not high after demolding, requiring a large amount of manpower and resources for rectification later. In addition, the construction process involves many steps, resulting in an excessively long construction period.

[0004] Therefore, how to improve the structure of expansion joints in the existing technology to achieve high construction accuracy and shorten the construction cycle is an urgent technical problem to be solved in the existing technology. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an expansion joint device for industrial plant floors, which can improve construction accuracy, eliminate the need for large amounts of manpower and material resources for subsequent rectification, and shorten the construction cycle and reduce construction costs.

[0006] The present invention relates to an expansion joint device for industrial plant floors, comprising a fire-resistant strip, an insulation strip assembly, and a wooden template. In use, the fire-resistant strip is installed on the installation foundation, the insulation strip assembly is positioned above the fire-resistant strip and fixedly connected to the installation foundation, and the wooden template is positioned above the insulation strip assembly and covers the insulation strip assembly, and is used to remove the template after the concrete is poured to form a reserved gap.

[0007] Furthermore, the fire-resistant strip includes a lower component, an upper component, and fire-resistant material disposed between the lower component and the upper component. The lower component is an arc-shaped structure with the opening facing upwards, and the upper component is a U-shaped structure with the opening facing upwards, and the two ends of the U-shaped structure are bent outwards to form connecting flanges.

[0008] Furthermore, the insulation strip assembly includes an installation plate, insulation material, insulation board, and connecting plate. The installation plate has an installation groove I, the insulation material is disposed in the installation groove I, the insulation board is located in the installation groove I and above the insulation material, the connecting plate is disposed above the insulation board, and the connecting plate has a connector. The installation base has a positioning hole that mates with the connector. In use, the connector is inserted into the positioning hole.

[0009] Furthermore, the connecting flange is provided with a through hole that mates with the connector, and in use, the connecting flange is located below the connecting plate.

[0010] Furthermore, the mounting groove I has a V-shaped structure, and the connector is a connecting bolt.

[0011] Furthermore, the insulation board is an extruded polystyrene board.

[0012] Furthermore, the wooden template is provided with a mounting groove II that opens toward the connecting plate, and the connecting plate is embedded in the mounting groove II.

[0013] The beneficial effects of this utility model are as follows: The industrial plant floor expansion joint device of this utility model can be integrally cast with the concrete floor by setting fire-resistant strips, heat insulation strip components and wooden formwork. Compared with the prior art, it does not require the use of formwork and eliminates the process of formwork removal, which can greatly save construction steps and improve the installation accuracy of expansion joints. It also eliminates the need for a lot of manpower and material resources to make corrections later. At the same time, after the formwork is formed, the wooden formwork can be removed, which facilitates the construction of subsequent processes and improves the construction quality of subsequent processes.

Detailed Implementation

[0020] like Figure 1-3 As shown: The industrial plant floor expansion joint device of this embodiment includes a fire-resistant strip 1, an insulation strip assembly 2, and a wooden formwork 3. In use, the fire-resistant strip 1 is installed on the installation foundation 6. The insulation strip assembly 2 is positioned above the fire-resistant strip 1 and fixedly connected to the installation foundation 6. The wooden formwork 3 is positioned above and covers the insulation strip assembly 2, and is used to create a reserved gap after the concrete pouring is completed. The installation foundation 6 is a structural slab with grooves (i.e., the expansion joint location). The structural slab is cast integrally with the main building structure. The expansion joint device is installed in the grooves. The fire-resistant strip 1, insulation strip assembly 2, and wooden formwork 3 are installed sequentially from top to bottom, with top and bottom being relative to each other. Figure 1 In the vertical direction, the fire-resistant strip 1 is generally composed of two steel plates and fire-resistant material 101 placed between the two steel plates. The fire-resistant strip 1 is connected to the installation base 6, and the insulation strip assembly 2 is positioned and connected to the installation base 6. Simultaneously, by covering the insulation strip assembly 2 with the wooden formwork 3, the expansion joint device can be integrally cast with the concrete floor 5 during pouring. After the concrete floor 5 is cast, the wooden formwork 3 can be removed, creating a reserved gap to facilitate subsequent construction processes. During subsequent construction, hard rubber and steel plates are installed within the reserved gap, which can achieve... The expansion joint is flush with the cast-in-place concrete floor 5, allowing for simultaneous polishing of both sides of the expansion joint during concrete finishing. This improves the installation accuracy of the expansion joint device. Compared to existing technologies that involve casting the expansion joint device along with the concrete floor 5 using a formwork and then removing the formwork before sequentially installing the expansion joint device, this structure eliminates the need for a formwork. The expansion joint device can be directly cast integrally with the concrete floor 5, improving the quality of the expansion joint, reducing subsequent maintenance costs, simplifying construction steps, accelerating construction progress, and saving construction costs.

[0021] In this embodiment, the fire-resistant strip 1 includes a lower component 102, an upper component 103, and fire-resistant material 101 disposed between the lower component 102 and the upper component 103. The lower component 102 is an arc-shaped structure with its opening facing upwards, and the upper component 103 is a U-shaped structure with its opening facing upwards, with both ends of the U-shaped structure bent outwards to form connecting flanges 104. The upper component 103 and the lower component 102 are generally made of thin steel plates. The arc-shaped structure is disposed at the lower part of the U-shaped structure and together with the U-shaped structure forms a space for placing the fire-resistant material 101. The upper and lower parts are relative to each other. Figure 1 In the vertical direction, the outer wall of the U-shaped structure is tightly attached to the installation foundation 6, and at the same time... Figure 2 As shown, the two ends of the U-shaped structure point outwards (relative to) Figure 3 The connecting flange 104 is formed by bending in the left and right directions. The fire-retardant material 101 is generally rock wool, etc., which is an application of existing technology and will not be described in detail here.

[0022] In this embodiment, the thermal insulation strip assembly 2 includes an installation plate 201, thermal insulation material 202, thermal insulation board 203, and a connecting plate 204. The installation plate 201 is provided with an installation groove I 205. The thermal insulation material 202 is disposed in the installation groove I 205. The thermal insulation board 203 is located in the installation groove I 205 and above the thermal insulation material 202. The connecting plate 204 is disposed above the thermal insulation board 203. The connecting plate 204 is provided with a connector 4. The installation base 6 is provided with a positioning hole that cooperates with the connector 4. In use, the connector 4 is inserted into the positioning hole. The width of the mounting plate 201 is greater than the width of the insulation plate 203. The insulation material 202 can be rock wool, etc., which is an application of existing technology and will not be described in detail here. The connecting plate 204 is used to cover the mounting groove I 205. When in use, the connector 4 is inserted into the positioning hole to fix the expansion joint device, so that the expansion joint device does not shift during the pouring of concrete floor 5, and the installation height of the expansion joint device can be controlled at the same time.

[0023] In this embodiment, the connecting flange 104 is provided with a through hole that mates with the connector 4. In use, the connecting flange 104 is located below the connecting plate 204. By providing a through hole on the connecting flange 104 that mates with the connector 4, the connector 4 can be inserted into the through hole and fixed in the positioning hole, thereby achieving the fixation of the fire-resistant strip 1. The overall structure is simple and reliable.

[0024] In this embodiment, the mounting groove I 205 has a V-shaped structure, and the connector 4 is a connecting bolt. The lower half of the mounting groove I 205 has a V-shaped structure, and the upper half of the mounting groove I 205 has a rectangular groove structure. The insulation board 203 is installed in the rectangular groove structure, and the connector 4 is a connecting bolt, which facilitates assembly.

[0025] In this embodiment, the insulation board 203 is an extruded polystyrene board. The extruded polystyrene board 203 has a certain strength and can also act as a formwork when pouring the concrete floor 5, thus the insulation board 203 serves a dual function of insulation and formwork.

[0026] In this embodiment, the wooden template 3 is provided with an installation groove II 301 that opens toward the connecting plate 204, and the connecting plate 204 is embedded in the installation groove II 301. The connection plate 204 fitting into the installation groove facilitates the installation and fixing of the wooden template 3.
