Description

Technical Field

[0001] This utility model relates to a positioning control component, specifically to a component for ultra-long...

[0002] The positioning control component for installing lattice columns in the negative void section belongs to the technical field of foundation pit support engineering in building construction. Background Technology

[0003] Generally speaking, with the development of the construction industry, high-rise buildings are becoming increasingly common, especially in urban centers where land resources are scarce. High-rise buildings are often accompanied by deep foundation pits, which often lack the conditions for slope protection. The design frequently considers internal concrete bracing as a support, and when constructing the support lattice columns, it is necessary to focus on controlling the verticality and orientation of the lattice columns.

[0004] The most primitive method of deep-buried lattice column construction involves using a crane to directly hoist the lattice columns to the designed elevation inside the borehole after drilling. At the borehole opening, the horizontal position of the lattice columns below ground level is adjusted solely by the subjective judgment of the operators. During hoisting, it is difficult to accurately control and correct the horizontal position of the lattice columns inside the borehole, which can negatively impact the stability and durability of the main structure later on, thus affecting the quality of construction.

[0005] Currently, the most commonly used traditional control method on construction sites relies on column suspension rods, which is ineffective, especially at the Qianqiao location where high precision is required. Poor control can affect subsequent construction and create potential quality risks.

[0006] A search revealed a patent publication number CN216516486U, entitled "An Improved Lattice Column Direction Control Device," which discloses a method for controlling the hoisting and positioning accuracy of lattice columns within a casing. The device features a positioning frame on the foundation at the top of the casing. The improved lattice column direction control device includes load-bearing rails, limiting reinforcing bars, and positioning reinforcing bars. The load-bearing rails are parallel and spaced apart on the positioning frame. The positioning reinforcing bars are fixed symmetrically to the center positions of the four sides of the lattice column. The limiting reinforcing bars are installed at the four top corners of the lattice column, and each limiting reinforcing bar has a lifting ring at its top, which is detachably inserted into the load-bearing rail. While this patent achieves lattice column direction control, it suffers from the following problems: only the orifice device is reusable; the device inside the orifice is not reusable. Furthermore, the use of lifting bars for correction lacks sufficient rigidity, hindering accurate control. It cannot be implemented at greater depths.

[0007] Another patent publication, CN205475256U, entitled "A Device for Controlling the Direction and Elevation of a Grid Column Below Ground," discloses a device comprising: positioning marks set on the hardened ground around the construction opening, wherein the positioning marks are located at positions on all four sides of the construction opening, and the intersection of the line connecting the upper and lower positioning marks and the line connecting the left and right positioning marks coincides with the center of the construction opening; a support bracket set on the hardened ground around the construction opening, the support bracket comprising an outer frame and an inner square frame connected to the outer frame, wherein the outer frame is set on the hardened ground, the center of the inner square frame coincides with the intersection point, two opposite sides of the inner square frame are parallel to the line connecting the upper and lower positioning marks, and the other two sides are parallel to the line connecting the left and right positioning marks; an adjusting tool head, one end of which is connected to the ground-side end of the grid column below ground; and a connecting member, the other end of which is connected to the connecting member, and the connecting member rests on the support bracket. Although the aforementioned device achieves extremely high control precision, its on-site operation is extremely difficult. After the lattice column piles are poured, they cannot be dismantled and reused until the following day, resulting in low turnover efficiency. High requirements are also placed on the flatness and bearing capacity of the borehole openings; in short, it is often very inconvenient.

[0008] Therefore, the key to solving the above-mentioned technical problems lies in developing an improved lattice column installation positioning control component that is more reliable and can be reused multiple times. Summary of the Invention

[0010] To solve the above problems and achieve the above-mentioned invention objectives, this utility model provides an improved lattice column installation positioning control component for ultra-long negative void sections, achieved through the following design structure and the following technical solution:

[0011] An improved lattice column installation positioning control component for ultra-long negative void sections is used for the installation positioning of lattice columns. The lattice column installation positioning control component includes:

[0012] The control column is connected at one end to the lattice column and at the other end to the hoisting equipment.

[0013] Positioning frame components, two of which are arranged relatively to each other. The two positioning frame components are detachably connected into one body by several connecting components and installed at the opening of the foundation pit for positioning the control column to achieve the positioning and installation of the lattice column. Among them:

[0014] Engaging parts are symmetrically provided at both ends of the bottom of the control column for engaging and installing the control column on the lattice column to form an integral structure.

[0015] Preferably, the control column is formed by enclosing four vertical rods and several frames coaxially connected within the four vertical rods to form an integral hollow square column.

[0016] The vertical rods are arranged pairwise opposite to each other; the frames are U-shaped frames.

[0017] Preferably, the positioning frame component includes:

[0018] Inner positioning frame;

[0019] Outer positioning frame, which is arranged outside the inner positioning frame;

[0020] Among them, both sides of the outer part of the two side rods of the inner positioning frame are connected to the inner walls of the two side rods of the outer positioning frame through connecting rods; the middle of the transverse connecting rod of the inner positioning frame is connected to the inner wall of the middle of the transverse connecting rod of the outer positioning frame through a positioning rod group.

[0021] Preferably, both the inner positioning frame and the outer positioning frame are in a "匚" - shaped structure as a whole;

[0022] External thread segments with opposite helix directions are provided at the ends of the two side rods of the inner positioning frame and the outer positioning frame.

[0023] Preferably, the positioning rod group is two connecting rods arranged parallel to each other. The two ends of the two connecting rods are respectively connected to the inner positioning frame and the outer positioning frame, and the widths of the two connecting rods of the positioning rod group are the same as the widths of the two corresponding control columns.

[0024] Preferably, the connecting component includes:

[0025] Connecting sleeve, and locking nuts are symmetrically connected and communicated with the outer side wall of the outer end of the connecting sleeve;

[0026] Tightening member, which is respectively connected to each locking nut.

[0027] Preferably, the connecting sleeve is a tubular structure with openings at both ends and hollow inside;

[0028] Or, internal thread segments with opposite thread directions are provided inside both ends of the connecting sleeve;

[0029] The tightening member is a common bolt.

[0030] Preferably, hoisting holes for connecting hoisting equipment to facilitate lifting or lowering are symmetrically and penetratingly provided at the top of the upper end of the control column. The hoisting holes are provided on a frame at the top end.

[0031] Preferably, the engaging member as a whole is a "C-shaped", "U-shaped" or "V-shaped" or "C-shaped" plate-like member with an open lower end.

[0032] The hoisting equipment is an electric hoist, a truck crane or a crane.

[0033] Preferably, an injection molding layer, an anti-rust layer, a waterproof layer and a warning layer are sequentially sprayed from the inside to the outside on the outer surfaces of the control column, the positioning frame assembly, the connecting assembly and the engaging member. Fluorescent powder is coated on the warning layer;

[0034] Among them, an anti-slip cushion that mates with it is provided on the inner surface of the engaging member. The anti-slip cushion is a rubber pad.

[0035] The working principle is as follows: Before using an improved lattice column installation and positioning control component with the above design structure for an ultra-long negative air section, it is necessary to transport the already fabricated lattice column installation and positioning control component to the designated construction location for installation as a standby through manual or corresponding handling equipment.

[0036] Before installation, this component is processed proportionally according to the lattice column size and actual construction conditions on site; the operator takes the above-prepared component to the position where the lattice column needs to be installed, and then installs and uses it.

[0037] During use, first, the operator first hoists and places the lattice column into the foundation pit hole through the hoisting equipment, and then hoists the control column of the present invention. The lower end of the control column is clamped to the lattice column through the engaging member to form an integral structure, and the engaging member is clamped into the lattice column, protruding 500 mm above the ground;

[0038] Subsequently, the operator first lays out the positioning frame assembly. When laying out, it is laid out according to the planar installation position of the lattice column. According to the laying-out result, the positioning frame assembly is accurately installed on the foundation pit opening through the connecting assembly. After the installation is firm and reliable and it is ensured that the installation is firm and the position is accurate, the direction control work of the lattice column can be carried out.

[0039] During the work, the positioning frame assembly is used on the ground to correct the direction of the control column, thereby controlling the direction of the lattice column and improving the qualification rate of the lattice column construction. The positioning frame assembly can effectively control the direction and position of the control column, thereby controlling the verticality and elevation of the lattice column, providing favorable conditions for the smooth progress of the next construction process. After the lattice column installation is completed, the position is re-measured and accepted, and the control column is lifted upward by hoisting equipment using a hoisting rope through the hoisting hole. The control column is then removed, and at the same time, the positioning frame assembly is removed from the pit opening and taken to the next construction section, where it can be installed and used in accordance with the above method.

[0040] During the above process, the positioning frame component of this utility model can be disassembled and moved to the next construction section for installation and use as needed.

[0041] Finally, as time goes by, when all the construction work is completed and the invention is no longer needed, the operators only need to clean and repair the various parts of the invention, and then transport them to the designated tool storage warehouse by hand or with appropriate handling equipment.

[0042] The beneficial effects of this utility model compared with the prior art are:

[0043] 1. This utility model is convenient and efficient to install: the steel column connects to the column and is raised above the ground, so that the column in the hole is continued on the ground and controlled. The installation operation is simple and convenient for workers.

[0044] 2. This utility model improves the construction quality of the column: the design is reasonable, the connection between the components is stable, and it can control the construction quality of the column inside the hole with high precision.

[0045] 3. The components of this utility model are easy to install and disassemble, can be reused, can improve construction efficiency, ensure construction quality, avoid or reduce the risk of rework in the later stage, and the use of this component can effectively control the verticality and elevation of the lattice column, providing favorable conditions for the smooth progress of the next process.

[0046] 4. This utility model can solve the problem of difficulty in controlling the elevation and direction of lattice columns on construction sites when the top elevation of the lattice column is lower than the ground level. It can control the elevation and position the direction of the lattice column even when its top elevation is lower than the original ground level. Regarding the direction control, this utility model uses a positioning mechanism with positioning rods to more accurately and quickly control the direction of the lattice column during the lowering process, ensuring the column's direction meets requirements. Regarding the elevation control, by controlling the connection between the column and the lattice column, the length of the lattice column is extended, achieving more intuitive and accurate control of its elevation.

[0047] 5. This utility model has a simple structure, is easy to operate, highly practical, and has a fast construction speed, greatly saving construction time; it is reusable, convenient to transport, and low in cost.

[0048] 6. The exterior of this utility model is coated with anti-rust paint and a waterproof layer, which can prevent rusting and extend the service life of the entire control component. It is environmentally friendly and saves resources. At the same time, the exterior of the control component is coated with a self-luminous fluorescent material, which can clearly mark the location of the control component at night or in dark indoor and underground construction environments. It can effectively play a safety reminder role, improve visibility, make it easy for people to identify, and increase safety in construction and life.

[0049] 7. This utility model adjusts the direction by positioning and laying out lines through a positioning mechanism at the pile foundation hole. It is designed to be detachable, and the positioning frame component can be disassembled or installed at any time according to actual construction needs to achieve calibration. It is not limited by the order of construction. It can also be disassembled and temporarily installed in other construction sections when calibration is not required, so as to control the column direction to be consistent with the design. This utility model is easy to install, safe and stable, can be reused multiple times, and effectively controls the construction quality of underground grid structure.

[0050] 8. Because this utility model is equipped with a locking component, it can quickly and accurately control the depth of the control column inserted into the lattice column, and the installation is faster and more convenient, achieving efficient and rapid installation and ensuring that the position of the control column exposed in the pile hole is more appropriate.

[0051] 9. The positioning mechanism provided in this utility model enables positioning via the ground direction, adjustment and control of the column direction, and ultimately control of the direction of the lattice column inside the hole, thereby controlling the construction quality of the underground lattice column.

[0052] 10. Because the inner surface of the snap-fit ​​component is provided with a matching anti-slip pad, which is a rubber pad with several anti-slip protrusions, this utility model can ensure the integrity of the overall structure of the snap-fit ​​component and the lattice column, while also increasing the friction at the connection, making the connection tighter and more reliable.

[0080] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0081] In summary, a more specific embodiment of this utility model is as follows:

[0082] like Figures 1 to 15 As shown, an improved lattice column installation positioning control component for ultra-long negative void sections is used for installing and positioning lattice columns 5. The component is characterized by comprising:

[0083] Control column 1, one end of control column 1 is engaged with lattice column 5, and the other end of control column 1 is connected to hoisting equipment 6;

[0084] Positioning frame components 2, two of which are arranged opposite to each other, are detachably connected as one unit by several connecting components 3 and installed at the pit opening. They are used to position the control column 1 and realize the positioning and installation of the lattice column 5; wherein:

[0085] The bottom ends of the control column 1 are symmetrically provided with locking parts 4, which are used to lock the control column 1 onto the lattice column 5 and connect them into an integral structure.

[0086] In this utility model, the positioning frame component 2 is used to achieve positioning through the ground direction, adjust and control the direction of the column 1, and ultimately control the direction of the grid column 5 in the hole, thereby controlling the construction quality of the underground grid 5.

[0087] The locking component 4 is welded to the control column 1 to control the column 1 and thus control the direction of the lattice column 5. Specifically, the locking component 4 is made of 10mm thick steel plate. The height is the depth to which the control column 1 is embedded in the lattice column 5, and it is used to embed the lattice column 5 to control its direction.

[0088] The positioning frame component 2 is designed to be detachable, thus enabling convenient installation of the positioning frame without being affected by on-site hoisting, and allowing installation to be carried out at an appropriate time according to actual construction needs.

[0089] The positioning frame assembly 2 is welded with steel bars of diameter 12. The outer frame size is 2.5m*2.5m, and the inner frame size is 1.2m*1.2m. The width of the two adjacent connecting rods 23 and the positioning rod group 24 is the width of the control column 1, which is used to control the positioning of the ground section of the column 1.

[0090] Furthermore, such as Figure 10 As shown, the control column 1 is formed by four uprights 11 and several frames 12 coaxially connected within the four uprights 11, forming a hollow square column.

[0091] The uprights 11 are arranged in pairs facing each other; the frame 12 is a mouth-shaped frame.

[0092] In this utility model, the upright 11 is an L-shaped angle steel; the frame 12 is a mouth-shaped frame body formed by four L-shaped angle steels connected to each other.

[0093] Furthermore, such as Figure 12 As shown, the positioning frame component 2 includes:

[0094] Inner positioning frame 21;

[0095] The outer positioning frame 22 is located outside the inner positioning frame 21;

[0096] The outer sides of the inner positioning frame 21 are connected to the inner walls of the outer positioning frame 22 via connecting rods 23; the middle part of the transverse connecting rod of the inner positioning frame 21 is connected to the middle inner wall of the transverse connecting rod of the outer positioning frame 22 via positioning rod group 24.

[0097] Furthermore, such as Figure 12As shown, the positioning rod group 24 is two connecting rods arranged parallel to each other. The two ends of the two connecting rods are respectively connected to the inner positioning frame 21 and the outer positioning frame 22. The widths of the two connecting rods of the positioning rod group 24 are the same as the widths of the two control columns 1 at the corresponding ends.

[0098] Specifically, as Figure 10 shown, the inner positioning frame 21 and the outer positioning frame 22 are both in a "C" - shaped structure as a whole;

[0099] The connecting sleeve 31 is a tubular structure with openings at both ends and a hollow interior;

[0100] In the present utility model, the connecting rod is a rod - shaped member, and the rod - shaped member is a steel bar or a round steel.

[0101] As Figure 13 and Figure 14 shown, the connecting component 3 includes:

[0102] A connecting sleeve 31, and locking nuts are symmetrically connected and communicated with the outer end side wall of the connecting sleeve 31;

[0103] Tightening members 32, and the tightening members 32 are respectively connected to the locking nuts.

[0104] Furthermore, as Figure 10 shown, hoisting holes 13 for connecting a hoisting device 6 to facilitate lifting or lowering are symmetrically and penetratingly opened at the top of the upper end of the control column 1. The hoisting holes 13 are arranged on a frame 12 at the top end.

[0105] Furthermore, the engaging member 4 is a plate - shaped member in a "C - shaped", "U - shaped", "V - shaped" or "C - shaped" with an open lower end as a whole.

[0106] The hoisting device 6 is an electric hoist, a truck crane or a crane.

[0107] Before the implementation of Example 1 is used, the fabricated lattice column installation and positioning control component needs to be transported to the designated construction location for installation as a standby through manual labor or corresponding handling equipment.

[0108] Before installation, this component is processed proportionally according to the size of the lattice column and the actual construction conditions on site; the operator takes the above - prepared component to the position where the lattice column 5 needs to be installed, and then installs and uses it.

[0109] When in use, first, the operator first hoists and places the lattice column 5 into the foundation pit hole through the hoisting device 6, and then hoists the control column 1 of the present utility model. The lower end of the control column 1 is engaged with the lattice column 5 through the engaging member 4 to form an integral structure, and the engaging member 4 is inserted into the lattice column 5, protruding 500 mm above the ground;

[0110] Subsequently, the operator first lays out the positioning frame component 2. During the laying out, the layout is carried out according to the planar installation position of the lattice column 5. Based on the layout result, the positioning frame component 2 is accurately installed on the pit opening through the connecting component 3. After the installation and connection are stable and reliable, and the installation is stable and the position is accurate, the direction control work of the lattice column 5 can be carried out.

[0111] During the work, the positioning frame component 2 is used on the ground to correct the direction of the control column 1, thereby controlling the direction of the lattice column 5 and improving the construction qualification rate of the lattice column 5. The positioning frame component 2 can effectively control the direction and position of the control column 1, thereby controlling the verticality and elevation of the lattice column 5, providing favorable conditions for the next construction process. After the installation of the lattice column 5 is completed, the position is re-measured and accepted, and the control column 1 is lifted upward by the hoisting equipment 6 using the hoisting rope 61 through the hoisting hole 13. The control column 1 can then be taken out. At the same time, the positioning frame component 2 is removed from the pit opening and taken to the next construction section and constructed according to the above installation and usage method.

[0112] During the above process, the positioning frame component 2 of this utility model can be disassembled and moved to the next construction section for installation and use as needed.

[0113] Finally, as time goes by, when all the construction work is completed and the invention is no longer needed, the operators only need to clean and repair the various parts of the invention, and then transport them to the designated tool storage warehouse by hand or with appropriate handling equipment.

[0115] This embodiment 2 is the same as other embodiments, except that the ends of the rods on both sides of the inner positioning frame 21 and the outer positioning frame 22 are provided with external thread sections with opposite directions of rotation.

[0116] The connecting sleeve 31 has internal thread sections with opposite directions inside both ends;

[0117] The clamping component 32 is a common bolt.

[0122] In this embodiment, when in use, the exterior is coated with anti-rust paint and a waterproof layer, which can prevent rusting and extend the service life of the entire control component. This achieves environmental protection and saves resources. At the same time, the exterior of the control component is coated with a self-illuminating fluorescent material, which can clearly mark the location of the control component at night or in dark indoor or underground construction environments. This can effectively play a safety warning role, improve visibility, make it easy for people to identify, and increase safety in construction and daily life.

[0123] Other uses are the same as in other embodiments and will not be repeated here.

[0124] Example 4

[0125] This embodiment 4 is the same as other embodiments, except that an anti-slip pad that matches the inner surface of the engaging part 4 is provided. The anti-slip pad is a rubber pad.

[0126] When this embodiment 4 is used, since the inner surface of the engaging component 4 is provided with a matching anti-slip pad, which is a rubber pad with several anti-slip protrusions, it can ensure the integrity of the overall structure of the engaging component 4 and the lattice column 5 while increasing the friction at the connection, making the connection tighter and more reliable.

[0128] Furthermore, in this invention, a polymer wear-resistant material is injection molded onto the injection molding layer; the anti-rust layer includes an epoxy zinc-rich primer and a chlorinated rubber topcoat, as well as an epoxy micaceous iron oxide intermediate paint located between the epoxy zinc-rich primer and the chlorinated rubber topcoat; the waterproof layer is a polyurethane waterproof coating; and the warning layer is a yellow or black reflective warning tape, reflective film, or reflective paint.
