Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a support device for construction openings. Background Technology

[0002] During construction, various openings are frequently encountered, such as stairwells, elevator shafts, and reserved openings. The roof slab above these openings requires effective support to ensure construction safety and structural stability. Traditional support methods have many problems. For example, timber supports have limited strength, are prone to deformation and damage, and have a low turnover rate, resulting in wasted resources. Some simple steel pipe support structures involve binding multiple steel pipes together, but the installation and dismantling process is cumbersome and requires significant manpower and time. Especially for irregularly shaped or large openings, existing support devices often fail to meet the support requirements, leading to poor support effectiveness and potential safety hazards.

[0003] Therefore, this patent application is filed. Utility Model Content

[0004] In response to the above-mentioned issues and to address the problems existing in the prior art, this utility model provides a support device for construction openings. Using I-beams as the base of the bottom support, it provides strong load-bearing capacity and can effectively support the load of the top slab above the opening, ensuring structural safety during construction.

[0005] The purpose of this utility model is to provide a support device for construction openings, including a bottom support body, a middle support member, and a top support mechanism. The bottom support body includes multiple I-beams, which are connected sequentially and / or perpendicular to each other. The middle support member is fixed on each of the I-beams, and the top end of each middle support member is connected to the top support mechanism. The top support mechanism is connected to the top surface of the construction opening.

[0006] As a preferred design, adjacent I-beams are fixedly connected by welding, and each I-beam is provided with multiple supporting inclined plates, which are arranged at linear intervals.

[0007] As a preferred design, each of the I-beams includes an upper support plate, a lower support plate, and a middle connecting plate. The middle support is fixedly connected to the upper support plate. The width of the upper support plate is smaller than the width of the lower support plate. Each of the supporting inclined plates is fixed within the groove space formed by the upper support plate, the lower support plate, and the connecting plate of each I-beam.

[0008] As a preferred design, the supporting inclined plates are symmetrically arranged on both sides of each of the I-beams.

[0009] As a preferred design, the central support member is a round tube, and each round tube is fixed to the I-beam by pipe clamps.

[0010] As a preferred design, the top support mechanism is a height-adjustable telescopic structure.

[0011] As a preferred design, the top support mechanism employs an electric hydraulic cylinder or a pneumatic cylinder.

[0012] As a preferred design, the top support mechanism includes a sleeve, an adjusting rod, and a supporting top plate. The sleeve is fixed to the middle support member, the adjusting rod is threadedly connected to the sleeve, and the supporting top plate is fixedly connected to the adjusting rod.

[0013] As a preferred design, the inner wall of the sleeve is provided with an internal thread, and the outer circumferential surface of the adjusting rod is provided with a matching external thread.

[0014] As a preferred design, the adjusting rod is fitted with an adjusting handle.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] (1) The support device provided by this utility model uses I-beams as the bottom support, which provides strong load-bearing capacity and can effectively support the load of the top plate above the opening, ensuring structural safety during construction. The combination of the round pipe and the I-beam further enhances the overall stability of the support device and reduces the possibility of shaking and deformation.

[0017] (2) Height Adjustability: The adjustable height mechanism at the top allows for flexible and precise adjustment of the support height according to the actual height of the roof slab and construction requirements, improving the adaptability of the support device to different construction scenarios. It can easily meet the support needs of buildings with standard floor heights or areas with special height requirements.

[0018] (3) Ease of installation and disassembly: The entire support device has a simple structure and the connection between the components is easy to operate. The installation of the I-beams and round pipes can be completed quickly using conventional construction tools, and the operation of the adjustable height mechanism at the top is also very convenient, which greatly shortens the installation and disassembly time, improves construction efficiency, and reduces labor costs.

[0019] (4) High versatility: The support device of this utility model is suitable for openings of various types and sizes. Whether the opening is square, round or irregular in shape, it can be effectively supported by reasonably arranging I-beams and round pipes.

[0026] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0027] Example 1:

[0028] A support device for construction openings includes a bottom support body, a middle support member, and a top support mechanism.

[0029] like Figure 1 As shown, the bottom support structure comprises multiple I-beams 1, which are sequentially connected and / or perpendicular to each other. Using I-beams 1 as the main structure of the bottom support provides high strength and stability, and the I-shaped cross-section can effectively withstand significant pressure and bending moment. Different specifications of I-beams 1 can be selected based on the size of the opening and load-bearing requirements. For example, lightweight I-beams 1 can be used for smaller openings with lower load requirements; while for larger openings or scenarios requiring greater loads, ordinary I-beams 1 or even larger sizes are selected. The I-beams 1 are laid laterally on the ground or foundation below the opening, and both ends can be securely connected to the ground via anchor bolts or other fixing devices to ensure the stability of the entire support device. The I-beams 1 can also be perpendicular structures, forming support in multiple directions with good support effect.

[0030] The central support is located between the bottom support and the top support mechanism, and is fixed to each of the I-beams 1. The top end of each central support is connected to the top support mechanism. The central support can be a circular tube 3, or other shapes. The circular tube 3 is perpendicular to the I-beam 1 and is connected to the I-beam 1 by welding or special pipe clamps to ensure a firm connection. The number and spacing of the circular tubes 3 can be determined according to actual support requirements. Generally, the spacing should not be too large to ensure that the top load can be evenly distributed. The circular tubes 3 not only connect the I-beams 1 and the top support mechanism, but also enhance the overall stability of the support device to a certain extent, sharing part of the load through their axial compressive strength.

[0031] The top support mechanism is connected to the top surface of the construction opening.

[0032] Because the heights of various openings differ during construction, it is often necessary to erect steel pipe support structures upwards or dismantle them downwards to accommodate openings of different heights. However, both installation and dismantling processes are cumbersome and difficult to adjust flexibly. Therefore, in this embodiment, the top support mechanism is designed as a height-adjustable and retractable structure. This top support mechanism can be an electric hydraulic cylinder or a pneumatic cylinder, which controls the extension and retraction of the piston rod by controlling the inflow and outflow of hydraulic oil, thereby quickly adjusting the support height. A threaded adjustment structure can also be used. In this embodiment, the top support mechanism includes a sleeve, an adjusting rod 5, and a supporting top plate 6. The sleeve is fixed to the circular pipe 3. It can be fixed by welding, or the sleeve can be integrally formed with the circular pipe 3. The inner wall of the sleeve has an internal thread, and the outer circumference of the adjusting rod 5 has a matching external thread. The adjusting rod 5 is threadedly connected to the sleeve, and the supporting top plate 6 is fixedly connected to the adjusting rod 5. The supporting top plate 6 is fixed to the top surface of the opening.

[0033] To further facilitate height adjustment, an adjustment handle 7 is fitted onto the outside of the adjustment rod 5 in this embodiment. By rotating the adjustment handle 7, the length of the screw extending out of the sleeve can be adjusted, thereby achieving precise adjustment of the support height.

[0034] Furthermore, in order to improve the support effect, such as Figure 1 As shown in the illustration, this embodiment also includes multiple supporting inclined plates 2. Each I-beam 1 is designed to include an upper support plate 101, a lower support plate 102, and a connecting plate 103 in the middle. The middle support is fixedly connected to the upper support plate 101. The width of the upper support plate 101 is smaller than the width of the lower support plate 102. Each supporting inclined plate 2 is fixed within the groove space formed by the upper support plate 101, lower support plate 102, and connecting plate 103 of each I-beam 1. The supporting inclined plates 2 are symmetrically arranged on both sides of each I-beam 1. The supporting inclined plates 2 on each I-beam 1 are linearly arranged and evenly spaced, which greatly enhances the load-bearing capacity of the bottom support and can effectively support the load of the top plate above the opening, ensuring structural safety during construction.

[0035] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the present invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the present invention, and these should also be considered within the scope of protection of the present invention.
