Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit enclosure, in particular to a foundation pit enclosure structure. Background Art

[0002] The foundation pit is a soil pit excavated at the foundation design location according to the base elevation and foundation plane dimensions, while the foundation pit support is a series of measures taken during construction in the foundation pit to prevent the surrounding soil from becoming unstable.

[0003] Existing foundation pit enclosures typically consist of slab (pile) walls, supports, and purlins. Workers first insert the slab (pile) walls into the ground, then excavate the surface soil, install the purlins, and finally install the supports. In this construction process, the supports are installed last. The supports are usually long strips or columns. Since the two purlins are fixed to the slab (pile) walls, the spacing between them varies depending on the position of the slab (pile) walls on both sides. The length of the supports is usually fixed, leaving gaps between the supports and some of the purlins during installation. At this point, a pad is needed in the gap, and cement or other methods are subsequently poured to ensure that the supports and the two purlins are in contact with each other, adding to the complexity of the installation process. To address this issue, we propose a foundation pit enclosure structure. Utility Model Content

[0004] The purpose of the utility model is to provide a foundation pit enclosure structure to solve the problem that when the support in the existing foundation pit enclosure is installed, there will be gaps at both ends due to the difference in the spacing between the purlins on both sides.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A retaining structure for a foundation pit comprises a plate wall inserted into the foundation pit; a plurality of modular purlins, wherein the modular purlins are plugged into each other and fixed to the outer side of the plate wall by bolts; and a support column, wherein both ends of the support column are equipped with a docking unit, and the docking unit is movable and adjustable at the outer end of the support column so that the length of the support column can be adjusted and is fixed to the modular purlin.

[0007] Preferably, a plug plate is fixed at one end of the combined purlin, and two plug pieces adapted to the plug plate are fixed at the other end. The plug plate and the plug pieces between two adjacent combined purlins are plugged into each other. The designed plug plate and the plug pieces cooperate with each other so that the adjacent combined purlins can be stably docked.

[0008] Preferably, the docking unit includes a sliding sleeve that is slidably connected to the outside of the support column, the sliding sleeve is provided with a notch, and a positioning protrusion that is slidably connected to the notch is fixed on the support column, the positioning protrusion is internally threaded with a positioning column, and a plurality of positioning holes that are compatible with the positioning column are provided on the outside of the sliding sleeve, and the outer end of the sliding sleeve and one of the inserts are fixed with docking parts that dock with each other. The designed docking unit can change the length of the support column, so that it can more conveniently offset with the combined purlins on both sides.

[0009] Preferably, the docking member includes a docking plate fixed to the outer end of the sliding sleeve and an arc-shaped piece fixed to one of the inserts, the docking plate and the arc-shaped piece are positioned by bolts, and the sliding sleeve and the combined purlin can be stably docked through the docking member.

[0010] Preferably, docking holes are provided on both the plug plate and the plug piece, and a docking column adapted to the docking hole is fixed to the outer end of the sliding sleeve. After the plug plate and the plug piece are plugged in, the docking holes on the two are aligned with each other, and the two docking holes aligned after plugging in are plugged in by using the designed docking column, so that the two combined purlins can be assisted in positioning.

[0011] Preferably, the lengths of the plug plate and the insert pieces are consistent, and the spacing between the two insert pieces is greater than the thickness of the plug plate. The size design allows adjacent modular purlins to be closely butted together.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In this solution, the support column is optimized and a docking unit is added. The sliding sleeve in the docking unit can be moved and adjusted, and it is fixed to the modular purlin with the docking parts. This satisfies the requirement of quick positioning and installation when the distance between the modular purlins on both sides is different, making installation convenient and reducing unnecessary steps.

[0014] 2. In this solution, the modular purlins are connected to each other through plug-in plates and plug-ins, making docking easier and facilitating installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] like Figure 1-Figure 3 As shown in the figure, a retaining structure of a foundation pit includes a plate wall 1 inserted into the foundation pit; a plurality of modular purlins 2, which are plugged into each other and fixed to the outer side of the plate wall 1 by bolts; and a support column 16, with docking units 3 installed at both ends of the support column 16. The docking unit 3 is moved and adjusted at the outer end of the support column 16, so that the length of the support column 16 can be adjusted and fixed to the modular purlin 2.

[0023] Specifically, by cooperating with the docking unit 3, the length of the support column 16 can be changed within a certain range, so as to meet the installation requirements of two rows of modular purlins 2 with a certain spacing difference, thereby improving the installation efficiency and eliminating the tedious steps of pouring cement.

[0024] For further reference, Figure 2 and Figure 5 , a plug-in plate 4 is fixed to one end of the modular purlin 2, and two plug-in plates 5 adapted to the plug-in plate 4 are fixed to the other end, and the plug-in plates 4 and the plug-in plates 5 between two adjacent modular purlins 2 are plugged into each other;

[0025] The lengths of the plug-in plates 4 and the plug-in pieces 5 are the same, and the spacing between the two plug-in pieces 5 is greater than the thickness of the plug-in plates 4. When personnel are combining adjacent modular purlins 2, they only need to connect the plug-in plates 4 at one end with the plug-in pieces 5 of the other modular purlin 2 to achieve docking, and then fix the modular purlin 2 to the board wall 1 with screws. The designed modular purlin 2 can facilitate personnel to quickly assemble the purlins and improve assembly efficiency.

[0026] For further reference, Figure 2-Figure 4The docking unit 3 includes a sleeve 6 that is slidably connected to the outside of the support column 16. The sleeve 6 is provided with a notch 7. A positioning protrusion 8 that is slidably connected to the notch 7 is fixed on the support column 16. The positioning protrusion 8 is internally threaded with a positioning column 9. A plurality of positioning holes 10 that are compatible with the positioning columns 9 are opened on the outside of the sleeve 6. A docking piece 11 that docks with each other is fixed on the outer end of the sleeve 6 and one of the inserts 5.

[0027] The docking member 11 includes a docking plate 12 fixed to the outer end of the sliding sleeve 6 and an arc-shaped piece 13 fixed to one of the inserting pieces 5 . The docking plate 12 and the arc-shaped piece 13 are positioned by bolts.

[0028] The moving operation steps of the docking unit 3 are as follows: First, the personnel first press the sliding sleeve 6 at one end against the insert 5 of the combined purlin 2 at one end, so that the docking plate 12 fits the arc-shaped piece 13, and then fix it with bolts. Subsequently, the personnel move the sliding sleeve 6 according to the spacing between the combined purlins 2 on both sides until the docking plate 12 fits the arc-shaped piece 13, and then rotate the positioning column 9 so that the positioning column 9 is engaged with the positioning hole 10 to achieve the positioning of the sliding sleeve 6, and then fix it with bolts so that the support column 16 is fixed against the combined purlin 2 on both sides through the docking plates 12 at both ends.

[0029] It should also be noted that the docking plate 12 is a circular plate that matches the arc-shaped piece 13, so that the fitting area is large and the docking is more stable.

[0030] like Figure 3-Figure 5 As shown, this is an embodiment of another docking method for the sliding sleeve 6 and the combined purlin 2. In this embodiment, docking holes 14 are formed on both the inserting plate 4 and the inserting piece 5. A docking post 15 that matches the docking hole 14 is fixed to the outer end of the sliding sleeve 6. After the inserting plate 4 and the inserting piece 5 are connected, the docking holes 14 on the two are aligned with each other.

[0031] It should be noted that after two adjacent modular purlins 2 are connected, the docking holes 14 on the insert plate 4 and the insert piece 5 are connected to each other, and then the personnel insert the docking column 15 at the outer end of the sliding sleeve 6 into the aligned docking holes 14 to achieve the assembly positioning of the two modular purlins 2 after docking, thereby improving the stability of the docking of adjacent modular purlins 2.

[0032] like Figure 3 and Figure 4 As shown, this is an embodiment of improving the stability between the sliding sleeve 6 and the support column 16. After the sliding sleeve 6 moves to the outer end of the support column 16, a gap is left between the sliding sleeve 6 and the outer end of the support column 16. At this time, personnel can pour cement into the sliding sleeve 6. As the cement hardens, the stability of the support column 16 and the sliding sleeve 6 bracket is improved.

[0033] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
