DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0022] Example: See Figure 1 - Figure 3In this embodiment, a construction foundation pit support template is provided, which is specifically used for supporting and stabilizing underground foundation pits and can improve the safety and convenience of operation during construction. The template specifically includes a base plate 11, and the base plate 11 is symmetrically provided with two sets of fixing plates 12. The fixing plates 12 are provided with clamps 14 connected and fixed to steel bars 13, and a detection port 15 is provided between the two pairs of clamps 14. The detection port 15 is slidably provided with a sliding cover 16.

[0023] Specifically, when using the construction foundation pit support formwork of the present invention, first place the base plate 11 vertically on one side of the support, then adjust the position of the fixing plate 12 on the support plate 21 according to the actual construction requirements, and after adjustment, the fixing plate 12 can be connected and fixed to the base plate 11 by a detachable method such as a threaded connection, and then the clamp 14 on the fixing plate 12 is connected and fixed to the steel bar 13 rooted in the foundation pit to complete the installation of the support formwork. During the construction process, the detection port 15 can be opened by sliding the slide cover 16 to observe or detect the solidification of the concrete in the support. For example, sampling can be carried out through the detection port 15 to check whether the concrete meets the design requirements for compressive strength to ensure its bearing capacity. The detection port 15 can be set near the bottom of the base plate 11, and can also detect the density of the concrete to prevent water in the foundation pit from penetrating into the support structure and causing weakening and damage. In this embodiment, the slide cover 16 is provided with a handle 17 to facilitate operation by construction personnel during inspection. Furthermore, the sliding cover 16 is made of a transparent material. This design allows for intuitive observation of the interior of the foundation pit support formwork through the transparent sliding cover 16 without opening the sliding cover 16. The use of the transparent sliding cover 16 greatly facilitates construction personnel in quickly inspecting the status of the support structure, particularly in conducting preliminary assessments of the quality of concrete pouring, whether there is water accumulation in the formwork, and the status of the internal steel structure, thereby enabling better implementation of non-destructive testing methods (such as rebound and ultrasonic methods).

[0024] The fixed plate 12 is slidably connected to the support plate 21. This sliding connection allows for adjustment of the position of the support formwork base plate 11, facilitating adjustments to the height of the support structure during foundation pit construction. A base 22 is positioned beneath the support plate 21. The bent portion of the base 22 is equipped with reinforcing ribs to increase the structural rigidity of the support plate 21. A drill rod 23 is threadedly connected to the base 22, allowing the support structure to be securely embedded in the foundation pit, providing enhanced load-bearing and anti-overturning capabilities.

[0025] The fixed plate 12 is symmetrically provided with a sliding portion 24, and the support plate 21 is symmetrically provided with a sliding groove 25 that is slidably adapted to the sliding portion 24. The support plate 21 is provided with a number of locking components 3 for fixing the fixed plate 12 and the support plate 21. The locking components 3 are used to achieve an effective locking function after adjusting the position of the fixed plate 12, ensuring that the support formwork can remain stable after adjustment, avoiding loosening caused by vibration of the operation of engineering machinery during construction.

[0026] See also Figure 3 In this embodiment, the locking component 3 includes a first rod 31 and a second rod 32 that are threadedly connected to each other. The inner sidewall of the chute 25 of the support plate 21 is provided with a through hole 33. The first rod 31 and the second rod 32 respectively pass through the through holes 33 on either side to contact the sliding portion 24. Specifically, the cooperation between the sliding portion 24 and the chute 25 allows the fixed plate 12 to be smoothly adjusted on the support plate 21 to adapt to different foundation pit environments and construction requirements. Through the threaded connection between the first rod 31 and the second rod 32 in the locking component 3, construction workers can manually tighten the two rods so that they pass through the through holes 33 in the inner sidewall of the chute 25 and contact the sliding portion 24, thereby effectively securing the fixed plate 12. Thus, after the sliding portion 24 is slid and adjusted to the appropriate position, it can be firmly locked into the chute 25 by threaded fastening, ensuring that the relative position between the fixed plate 12 and the support plate 21 remains stable.

[0027] The first rod body 31 and the second rod body 32 are respectively provided with a first nut 34 and a second nut 35. Construction personnel can use a wrench to drive the first nut 34 and the second nut 35 to rotate in opposite directions to adjust the overall length of the first rod body 31 and the second rod body 32, which is convenient for locking and disassembly. In the present embodiment, the second nut 35 is provided with a screw 36, and the first rod body 31 is provided with an internal thread 37 that is threadedly connected and adapted to the screw 36. In the present embodiment, the first rod body 31 and the second rod body 32 are threadedly connected and adapted, and the threaded structure has the ability of self-locking, thereby improving the stability of the overall structure. Even if subjected to external impact or vibration (generated by engineering machinery operations) during the construction process, the connection between the fixed plate 12 and the support plate 21 is not easy to loosen, thereby ensuring the safety of the construction operation of the support formwork.

Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
