[0002] In the field of construction engineering, with the increasing demands for construction efficiency, safety, and environmental protection, lightweight new aluminum plate support boxes have emerged. Traditional materials for constructing external support plates for foundation pits have many limitations, such as heavy weight and inconvenient installation. This lightweight new aluminum plate support box, however, uses advanced materials and processes, possessing advantages such as light weight, high strength, and convenient installation. It can more efficiently and stably construct support plates, effectively protecting the foundation pit and meeting the needs of modern construction development.

When facing construction areas of different sizes, the support box devices may be too far apart, making it impossible to form a tight and effective support system between adjacent support boxes. During the foundation pit construction process, when encountering lateral earth pressure, weak links are easily formed in areas with excessive spacing, leading to the danger of local deformation or even collapse of the foundation pit sidewall.

[0020] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model provides, for example Figure 1-3 The steel plate support box device shown includes two support plate bodies 3. The inner front and rear ends of the two support plate bodies 3 are respectively provided with slots 1. Multiple support positioning holes 2 are equidistantly arranged on the inner side of the slots 1. Support outer sleeve 6 and support inner sleeve 4 are respectively provided on the inner side of the two slots 1. Positioning holes 10 are provided at the connection positions of the support outer sleeve 6 and support inner sleeve 4 with the support positioning holes 2 in the slots 1 at both ends. Multiple adjustment holes 5 are provided at the connection positions of the support inner sleeve 4 and support outer sleeve 6. Multiple fixing holes 7 and positioning holes 10 are provided at equal intervals on the front side of the support outer sleeve 6. Positioning pins 8 are provided on the inner side of the support positioning holes 2.
[0022] In this embodiment, the user can place the two aluminum plate support plate bodies 3 in parallel, and the spacing can be adjusted according to the construction space requirements. It is recommended to maintain an initial spacing of 1-2 meters.
[0023] Use a laser level to calibrate the verticality of the support plate body 3 to ensure that the opening direction of the slot 1 is consistent.
[0024] Next, the main body is fixed to the ground or foundation platform using expansion bolts through the pre-embedded bolt holes at the bottom of the support plate body 3.
[0025] Next, loosen the fixing screw at the connection between the outer support sleeve 6 and the inner support sleeve 4, so that the inner support sleeve 4 is in a free sliding state.
[0026] Two workers hold the inner support sleeve 4 and the outer support sleeve 6 respectively, and push and pull them axially to the target length.
[0027] A hydraulic jack can also be used to push the end of the sleeve, and a measuring tape can be used to ensure that the synchronous elongation error on both sides is ≤2mm.
[0028] Next, observe the alignment of the fixing hole 7 on the outer sleeve 6 with the adjusting hole 5 on the inner sleeve 4.
[0029] Then insert the fixing screw and pre-tighten the nut to initially fix the sleeve length.
[0030] Insert the positioning pin 8 through the support positioning hole 2 on the outside of the slot 1, and then through the positioning holes 10 of the inner support sleeve 4 and the outer support sleeve 6 in sequence.
[0031] Ensure that the locating pin 8 fully penetrates all holes, with the end of the R-type retaining pin 9 protruding at least 5mm from the mounting thread.
[0032] Screw the R-type locking pin 9 into the thread at the end of the positioning pin 8, and tighten it clockwise with a wrench until the locking pin is fully fitted to the back of the slot 1.
[0033] Check that the R-type locking pin 9 is securely engaged to prevent loosening that could cause the positioning pin 8 to come out.
[0034] In the overlapping area of the outer sleeve 6 and the inner sleeve 4, three sets of symmetrically distributed fixing holes 7 and adjusting holes 5 are selected.
[0035] Insert the retaining screw and apply torque to the recommended standard value to ensure the rigidity of the sleeve connection.
[0036] like Figure 1-3 As shown, an R-type locking pin 9 is provided at the rear side of the positioning pin 8. The R-type locking pin 9 is connected to the end of the positioning pin 8 by a threaded connection. The positioning pin 8 passes through the slot 1, the inner support sleeve 4, and the outer support sleeve 6 through the support positioning hole 2 and the fixing hole 7, respectively. The multiple adjustment holes 5 and the multiple fixing holes 7 are spaced at the same distance. A fixing screw is provided in the fixing hole 7, and the fixing screw passes through the fixing hole 7. The inner support sleeve 4 is connected to the outer support sleeve 6 by an insertion connection, and the inner support sleeve 4 can move within the outer support sleeve 6. The two symmetrically arranged support plate bodies 3 have the same volume and area.
[0037] Preferably, the length of this new type of support inner sleeve 4 and support outer sleeve 6 can be adjusted via adjustment hole 5 and fixing hole 7.
[0038] In the initial state, the inner support sleeve 4 and the outer support sleeve 6 are in a state where their lengths are not adjusted.
[0039] When the length of the support box device needs to be adjusted to adapt to different construction needs, the operator can manually push the inner support sleeve 4 or the outer support sleeve 6 to move the inner support sleeve 4 inside the outer support sleeve 6.
[0040] After determining the desired length by observing the actual requirements, use a fixing screw to pass through the fixing hole 7 and adjustment hole 5 on the supporting outer tube 6.
[0041] Tighten the outer nut onto the fixing screw to fix the relative position of the inner support sleeve 4 and the outer support sleeve 6, thereby fixing the length.
[0042] The advantage of this structure is that the length of the support box device can be flexibly adjusted according to different construction scenarios, improving the adaptability of the device. At the same time, the fixing method of the fixing screws and nuts is simple and reliable, ensuring the stability of the device during use.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
