Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a modular small space bottom formwork support device. Background Technology

[0002] During building construction, there is often a problem of narrow space between beams / slabs, especially when beams / slabs are misaligned and overlapped. Due to the small space, the bottom formwork of the upper beams / slabs is difficult to support and the construction quality is not easy to control, which increases construction costs and delays the project schedule.

[0003] Currently, the bottom formwork support for small spaces mostly uses brick blocks, concrete blocks, or foundation jacks, but these methods have the following problems:

[0004] 1. Low adjustment efficiency: Traditional jacks require manual adjustment one by one, which is time-consuming and labor-intensive, and it is difficult to ensure synchronization;

[0005] 2. Poor versatility: Fixed-size support devices cannot adapt to the needs of different beam and slab widths;

[0006] 3. Lack of monitoring function: The support status cannot be monitored in real time during construction, which can easily lead to deformation or collapse of the formwork due to uneven stress.

[0007] 4. Heavy materials: The metal crossbar and jack are heavy, making them difficult to move and disassemble. Utility Model Content

[0008] The purpose of this utility model is to overcome the defects of the prior art and provide a modular small space bottom formwork support device, which can effectively overcome the problem that the bottom formwork of the upper beam is difficult to support due to the narrow space when two beams and slabs are overlapped. At the same time, the drive system is used to synchronously control multiple telescopic components to ensure the uniformity of force during the formwork support process.

[0009] The objective of this utility model is achieved through the following technical solution:

[0010] A modular small-space bottom formwork support device includes multiple sets of support components disposed within the bottom formwork. Each set of support components includes multiple telescopic members and crossbars disposed on the upper and lower sides of the telescopic members. The crossbars abut against the beam plate, and the multiple telescopic members are all connected to a drive system.

[0011] In one embodiment, multiple telescopic members in each set of the support components are slidably connected to the crossbar.

[0012] In one embodiment, sliding grooves are provided on both sides of the crossbar, and the telescopic member is slidably connected to the crossbar through a flange that matches the sliding groove.

[0013] In one embodiment, the telescopic component is an electro-hydraulic jack, the drive system is a hydraulic adjustment system, and multiple electro-hydraulic jacks are connected to the hydraulic adjustment system.

[0014] In one embodiment, an LVDT displacement sensor is also provided inside the bottom mold, and the displacement sensor is located between two adjacent support components.

[0015] In one embodiment, the LVDT displacement sensor also has a communication module electrically connected to the receiving module to transmit the support height in real time.

[0016] In one embodiment, the crossbar is made of multiple square aluminum alloy tubes spliced ​​together as one piece.

[0017] In one embodiment, the wall thickness of the square aluminum alloy tube is 3 to 5 mm.

[0018] In one embodiment, two adjacent square aluminum alloy tubes are joined together by a snap-fit ​​interface.

[0019] In one embodiment, the flange has a U-shaped structure, with one end connected to the telescopic member and the other two sides having sliders that match the sliding groove.

[0020] The beneficial effects of this utility model are as follows:

[0021] (1) It can effectively overcome the problem that the bottom formwork of the upper beam is difficult to support due to the narrow space when the two beams are overlapped. At the same time, the drive system can be used to control multiple expansion joints in a synchronous manner to ensure the uniformity of stress during the formwork support process.

[0022] (2) It is low in cost, simple in structure, easy to use, and the whole device can be reused. It is suitable for various small space bottom formwork support scenarios and is easy to promote. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] This utility model provides a modular small-space bottom formwork support device, such as... Figure 1 As shown, it includes multiple sets of support components installed in the bottom formwork. Each set of support components includes multiple telescopic components and crossbars 2 installed on the upper and lower sides of the telescopic components. The crossbars 2 abut against the beam plate 4. The multiple telescopic components are all connected to the drive system.

[0033] It should be noted that, as Figure 1 As shown, when facing the problem of narrow space between beams and slabs 4, the expansion joints in multiple sets of support components are used for support. At the same time, the expansion joints in multiple sets of support components are controlled synchronously by an external drive system. Compared with the traditional formwork method, there is no need to adjust them one by one, which saves formwork time significantly while ensuring the synchronicity of the formwork operation and improving the stability of the operation.

[0034] In one embodiment, such as Figure 1 and Figure 2 As shown, multiple telescopic components in each support assembly are slidably connected to the crossbar 2;

[0035] Specifically, such as Figure 3 As shown, sliding grooves 201 are provided on both sides of the crossbar 2, and the telescopic component is slidably connected to the crossbar 2 through a flange 7 that matches the sliding grooves 201.

[0036] It should be noted that by opening sliding grooves 201 on both sides of the crossbar 2, the telescopic components can slide on the crossbar 2. This makes it convenient to flexibly adjust the fulcrum spacing between the telescopic components on the same crossbar 2 when facing beams and slabs 4 of different sizes, so as to adapt to different formwork scenarios.

[0037] In one embodiment, the telescopic component is an electric hydraulic jack 1, the drive system is a hydraulic adjustment system 3, and multiple electric hydraulic jacks 1 are connected to the hydraulic adjustment system 3. That is, the hydraulic adjustment system 3 can drive multiple electric hydraulic jacks 1 at the same time, eliminating the need for operators to operate in a small space, while ensuring the synchronization of each fulcrum.

[0038] Specifically, in this embodiment, the telescopic component can be selected from two or more linked electric hydraulic jacks 1 according to the width and weight of the beam plate 4. The lifting capacity of a single electric hydraulic jack 1 is 5T, and the pump body + stroke height is 40~50cm.

[0039] In one embodiment, such as Figure 1 As shown, an LVDT displacement sensor 5 is also installed inside the bottom mold. The displacement sensor is located between two adjacent support components. The LVDT displacement sensor 5 also has a communication module that is electrically connected to the receiving module to transmit the support height in real time. That is, through the LVDT displacement sensor 5, the support height and support pressure and other parameter information are sent to the receiving module in real time, so that the operator can observe the formwork support process in real time on the operating table / control console with the receiving module, so as to make timely adjustments to the hydraulic adjustment system 3.

[0040] In one embodiment, the crossbar 2 is made of multiple square aluminum alloy tubes spliced ​​together, and the wall thickness of the square aluminum alloy tubes is 3 to 5 mm.

[0041] In one embodiment, such as Figure 3 As shown, the flange 7 has a U-shaped structure, with one end connected to the telescopic component and the other two sides having sliders that match the sliding groove 201.

[0042] Specifically, two adjacent square aluminum alloy tubes are spliced ​​together by snap-fit ​​interfaces, which makes it easy to quickly assemble crossbars 2 of the corresponding size according to the size of beam 4, adapting to different span requirements. Moreover, the overall structure adopts a standardized design, so even if a part is damaged, it can be replaced individually, reducing material waste.

[0043] In one embodiment, when using this device, the position and number of jacks are adjusted according to the width and weight of the beam slab 4, and the lifting height of the electric hydraulic jack 1 is adjusted so that the horizontal bar 2 above it is at the same elevation as the bottom of the beam. According to the overlap length of the beam slab 4, one set of this device is placed at intervals of 100-200cm to ensure the stability of the entire formwork 6. Then, the steel bars are tied and the concrete is poured. After the concrete reaches the demolding strength, the hand crank is turned in the opposite direction, the jacks fall back, and the device can be removed and the formwork 6 is removed. That is, the entire device can be reused, saving construction costs.
