Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a formwork support device for the bottom of a house beam. Background Technology

[0002] In the construction of buildings, the support of the beam bottom formwork is a crucial step, directly affecting the quality of concrete pouring and the safety of the construction process. Traditional beam bottom formwork support devices have many shortcomings.

[0003] On the one hand, its height adjustment function is limited, making it difficult to adapt to the complex terrain of different construction sites and the support requirements of beam bottom formwork of different heights. As a result, when facing uneven ground or needing to precisely adjust the height of the formwork, construction workers often need to spend a lot of extra time and effort to level the ground or use other auxiliary means to achieve the appropriate height. This not only increases construction costs but also reduces construction efficiency.

[0004] On the other hand, traditional beam bottom formwork support devices are not convenient enough for fixing and adjusting the keel, and cannot effectively ensure the stability and uniformity of the keel during the support process, which further affects the support effect and construction quality of the beam bottom formwork. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a formwork support device for the bottom of a house beam.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A support device for the bottom formwork of a building beam includes a support base, a support pipe, and an adjustable base; the bottom of the support pipe is provided with an adjustable base that can adjust the height; the top of the support pipe is provided with a support base for supporting the bottom formwork of the beam; the support base includes a support plate whose bottom is connected to the support pipe, and a keel is provided between the support plate and the bottom formwork of the beam, and right-angle baffles for limiting the keel are provided at the four corners of the top of the support plate.

[0008] Preferably, the support plate has two countersunk holes spaced apart between each of the two adjacent right-angle baffles, and the countersunk holes are threaded with adjusting bolts for adjusting the height of the keel.

[0009] Preferably, the bottom of the support plate is connected to the support tube via a connector.

[0010] Preferably, the adjusting base includes an adjusting sleeve, an adjusting rod is threadedly connected to the top of the adjusting sleeve, and a connector corresponding to the support tube is provided on the top of the adjusting rod.

[0011] Preferably, the adjusting rod is provided with a plurality of insertion holes spaced apart along the circumferential direction.

[0012] Preferably, the connector is rotatably connected to the adjusting rod.

[0013] Preferably, the bottom of the adjusting base is provided with a telescopic rod; the telescopic rod includes a sleeve, a rod is movably inserted into the sleeve, and the rod body is provided with a plurality of adjusting holes at intervals along its length; the top of the sleeve is provided with a pin hole, and a pin capable of passing through the corresponding adjusting hole is inserted into the pin hole.

[0014] Preferably, the telescopic rod is provided with a foot pad at the bottom, and the bottom of the foot pad is provided with multiple concentric annular grooves or annular protrusions.

[0015] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0016] (1) The present invention has a simple structure. By setting an adjustable base with adjustable height, it can easily adapt to the terrain requirements of different construction sites. It does not require large-scale leveling of the ground, which greatly saves construction preparation time, improves construction efficiency, and also reduces construction costs.

[0017] (2) The connection structure between the support base and the keel of this utility model is reasonably designed. The right-angle baffle can effectively prevent the keel from falling off, while the setting of the adjusting bolt can flexibly adjust the height of the keel according to the different specifications of the keel, ensuring that the keel is subjected to uniform force, and further enhancing the stability and reliability of the entire support system.

[0018] (3) This utility model further solves the problem of limited height adjustment capability of the adjustment base by adding a telescopic rod at the bottom of the adjustment base. Especially when a large stroke adjustment is required, it can significantly improve the adjustment efficiency and reduce the labor intensity and adjustment time of the construction personnel. Specifically, when facing the need for large stroke adjustment, the construction personnel can first pull out the pin and quickly adjust the height position of the rod, and then insert the pin to lock it, thereby quickly achieving a large range of height adjustment. If the adjustment is not in place, the adjustment base can be used for fine adjustment. This combined adjustment method ensures both the speed and accuracy of adjustment, making the entire support device more flexible to adapt to the height differences of different construction sites and the height requirements of the beam bottom formwork, thus improving the convenience and efficiency of construction.

[0019] (4) The present invention further enhances the stability and ground adaptability of the entire device by setting foot pads at the bottom of the telescopic rod. The foot pads can stably support the telescopic rod and the adjustment base, and the annular groove or annular boss design at the bottom effectively increases the friction with the ground, so that the device can maintain good stability under various ground conditions and textures.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] In the description of this utility model, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. They are only used to facilitate the description of this utility model and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Example 1

[0029] Combined with appendix Figures 1-5 A support device for the bottom formwork of a building beam includes a support base 1, a support pipe 2, and an adjusting base 3; wherein, the bottom of the support pipe 2 is equipped with an adjusting base 3 that can adjust its height, and the top of the support pipe 2 is equipped with a support base 1 for supporting the bottom formwork of the beam 4.

[0030] Specifically, as the main supporting structural component, its length is fixed, and to facilitate procurement and reduce costs, it can be made from commercially available standard steel pipes. The adjustable base 3, which works in conjunction with the supporting pipe 2, has a practical function of adjusting its height. This design allows the adjustable base 3 to easily adapt to the diverse needs of different construction sites. In actual construction, by flexibly adjusting the height of the adjustable base 3, the potential length error of the supporting pipe 2 can be effectively compensated for, thereby precisely adjusting the height of the supporting base 1. This provides stable and precise support for the beam bottom formwork 4 above the supporting base 1; and it can adjust the levelness of the beam bottom formwork 4, avoiding construction quality problems caused by unstable support or levelness deviation.

[0031] As attached Figure 4 As shown, the adjusting base 3 includes an adjusting sleeve 3-1. An adjusting rod 3-2 is threadedly connected to the top of the adjusting sleeve 3-1, and the top of the adjusting rod 3-2 has a connector 3-3 that corresponds to and can be inserted into the support tube 2. In actual use, the connector 3-3 needs to be accurately inserted into the bottom of the support tube 2. Since the adjusting rod 3-2 and the adjusting sleeve 3-1 are threadedly connected, rotating the adjusting rod 3-2 causes relative rotation between the adjusting rod 3-2 and the adjusting sleeve 3-1, thereby adjusting the height of the adjusting base 3. Ultimately, this achieves the purpose of precisely adjusting the height of the support base 1 to meet the requirements of the beam bottom formwork 4 support height in different construction scenarios.

[0032] It is worth mentioning that, to prevent the adjusting rod 3-2 from rotating along with the support tube 2 during the adjustment process, thus affecting the stability of the entire device, the plug 3-3 is rotatably connected to the adjusting rod 3-2. This design ensures both the flexibility of adjustment and the stability during the adjustment process, thereby improving construction safety.

[0033] Furthermore, the adjusting rod 3-2 has multiple sockets 3-4 evenly spaced along the circumference. This design allows the operator to easily insert a wrench into the corresponding socket 3-4 during adjustment, thereby easily driving the adjusting rod 3-2 to rotate; the structure is simple, the operation is very convenient, greatly improving construction efficiency and reducing the difficulty of operation for construction personnel.

[0034] As attached Figure 2 and 3As shown, the support base 1 includes a support plate 1-1 whose bottom is connected to the support pipe 2. A keel 5 is installed between the support plate 1-1 and the beam bottom formwork 4. The keel 5 enhances the strength and stability of the entire support structure and effectively distributes the pressure on the beam bottom formwork 4, preventing deformation or damage due to excessive local pressure. To better secure the keel 5 and prevent accidental detachment during assembly, right-angle baffles 1-2 are installed at the four corners of the top of the support plate 1-1 to limit the movement of the keel 5.

[0035] It is important to note that the height of the right-angle baffle 1-2 must be less than the thickness of the keel 5. This design aims to ensure that the keel 5 can fully and effectively support the bottom formwork 4 of the beam, guaranteeing the stability and reliability of the entire support system. If the height of the right-angle baffle 1-2 is too high, the keel 5 will not be able to effectively contact the bottom formwork 4 of the beam, thus failing to effectively support it.

[0036] In addition, the support plate 1-1 has multiple countersunk holes spaced between adjacent right-angle baffles 1-2. Adjusting bolts 1-3, used for adjusting the height of the keel 5, are threaded into these countersunk holes. Depending on actual construction needs, the keel 5 can be made of either rectangular tubing or timber. If rectangular tubing is used as the keel 5, its high dimensional accuracy, produced to standard dimensions, eliminates the need for adjusting the height using bolts 1-3 during installation, thus providing good support for the beam bottom formwork 4. However, the cost of using rectangular tubing is relatively high. If timber is chosen as the keel 5, the cost is lower, and timber is easy to cut and process on-site, allowing for flexible length adjustments to suit different construction scenarios. However, timber often lacks dimensional consistency, especially when multiple timbers are placed between adjacent right-angle baffles 1-2. Differences in the dimensions of each timber make it difficult to ensure uniform stress distribution across all timbers. In this situation, the height of the timber can be adjusted by rotating the corresponding adjusting bolts 1-3 to ensure that the force is evenly distributed, thereby guaranteeing the stability and reliability of the entire support system.

[0037] It is particularly important to note that when installing adjusting bolt 1-3, its large end can be placed into the countersunk hole on the support plate 1-1, and a pin can be installed at its small end. This has two advantages: firstly, it makes it easier for construction workers to rotate adjusting bolt 1-3, making the operation more effortless and convenient; secondly, the pin effectively prevents adjusting bolt 1-3 from accidentally falling off or being lost during use, ensuring the smooth progress of the construction process.

[0038] Furthermore, the bottom of the support plate 1-1 is connected to the support tube 2 via connector 1-4, which makes the connection convenient and quick, and also facilitates separation, transportation or storage.

[0039] In actual construction, to further improve the support effect of the beam bottom formwork 4 and avoid deformation or damage due to excessive local stress, multiple beam bottom formwork support devices can be installed to support the beam bottom formwork 4 together, as shown in the attached diagram. Figure 5 As shown, by rationally arranging multiple support devices for the bottom formwork of the house beams, the pressure borne by the bottom formwork 4 of the beams can be evenly distributed, ensuring the stability and safety of the entire construction structure and providing a reliable guarantee for the construction of the house. Example 2

[0040] During actual construction, a significant problem was discovered: the height adjustment capability of the adjustable base 3 has certain limitations. Especially when facing situations requiring large stroke adjustments, the entire adjustment process becomes particularly time-consuming and laborious, resulting in very low efficiency and applicability only to minor adjustments. Therefore, to effectively address these technical shortcomings, this embodiment has undergone further improvements and optimizations based on the original design.

[0041] Combined with appendix Figure 4 A formwork support device for the bottom of a building beam, the main difference from Embodiment 1, is that, based on Embodiment 1, the adjusting base 3 is provided with a telescopic rod 6 at its bottom. The telescopic rod 6 includes a sleeve 6-1, inside which a rod 6-2 is movably inserted. To achieve precise and flexible adjustment, the rod 6-2 has multiple adjusting holes 6-3 spaced apart along its length. Simultaneously, a pin hole is provided at the top of the sleeve 6-1, into which a pin 6-4, capable of passing through the corresponding adjusting hole 6-3, is inserted.

[0042] When a significant stroke adjustment is required during construction, the operator can first pull out the pin 6-4. This allows the rod 6-2 to be easily and quickly adjusted within its range of motion. After adjusting to a suitable approximate height, align one of the adjustment holes 6-3 on the rod 6-2 with the pin hole of the sleeve 6-1. Then, reinsert the pin 6-4 into the pin hole to quickly lock the rod 6-2, thus achieving rapid large stroke adjustment. If slight deviations remain in the height adjustment after the above steps, and the required precision is not fully achieved, further fine-tuning can be performed using the base 3 to ensure the overall height of the device accurately meets construction needs. This effectively improves adjustment efficiency, saves construction time, and reduces the workload of construction personnel.

[0043] Furthermore, to enhance the stability and ground adaptability of the entire device, a foot pad 7 is installed at the bottom of the telescopic rod 6. The bottom of the foot pad 7 has multiple concentric grooves or annular protrusions. The main function of the foot pad 7 is to stably support the telescopic rod 6 and the adjusting base 3 above it, ensuring the stability of the entire device during construction. The grooves or annular protrusions at the bottom of the foot pad 7 effectively increase its contact area and friction with the ground, further enhancing the overall stability of the device. This allows it to maintain good support under different ground textures and conditions, effectively preventing the device from shaking or tipping over due to uneven or slippery ground, providing a more reliable safety guarantee for the construction process.

[0044] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
