Description

Technical Field

[0001] The present application relates to the field of peripheral ground construction, and in particular to an anti-settlement structure and construction process for the peripheral ground of a building. Background Art

[0002] Common practices for backfilling areas outside buildings include ground compaction and pine pile ground reinforcement.

[0003] Dynamic ground compaction involves compacting backfill soil layer by layer around the building's perimeter to consolidate and compact the soil. While this method offers the advantage of ease of construction, the vibrations generated during the compaction process can adversely affect the main structure.

[0004] The pine pile ground reinforcement method involves driving a predetermined number of pine piles at designated intervals around the building's perimeter. A bedding layer of crushed stone is then laid, followed by surface construction. The pine piles replace the same volume of low-modulus, low-strength soil. The piles are hammered into the soil, forcing the existing soil at the pile hole into a lateral compression, increasing the density of the soil around the piles. However, the driven pine piles can interfere with the raised portion of the basement slab.

[0005] Furthermore, both the ground compaction method and the pinewood pile ground reinforcement method suffer from insufficient stability. After the ground around the building is completed, the ground and the main structure can easily become detached due to the settlement difference. Furthermore, because the ground intersects the main building, it is subject to frequent changes in temperature, dryness, and wetness, making the surrounding ground extremely prone to cracking and collapse, seriously affecting the overall quality and appearance of the building. This can also easily cause water leaks at the base of the main building's walls, leading to wasteful rework and subsequent repairs. Summary of the Invention

[0006] In order to improve the problem of ground cracking and collapse caused by the settlement difference between the main structure of a building and the surrounding ground, the present application provides an anti-settlement structure and construction process for the ground surrounding a building.

[0007] In the first aspect, the present application provides a building perimeter ground anti-settlement structure that adopts the following technical solutions:

[0008] A ground anti-settlement structure for the periphery of a building, comprising a beam slab connected to the side wall of a basement and a frame column connected to the crown beam on the top of a foundation pit support pile, wherein the upper end of the frame column is connected to the beam slab;

[0009] Column reinforcement is arranged inside the frame column, and the column reinforcement extends to the inside of the crown beam. Beam reinforcement is arranged inside the beam slab, and the beam reinforcement extends to the inside of the basement side wall. A backfill area is arranged on the lower side of the beam slab, a concrete layer is arranged on the upper side of the beam slab, and a surface layer is arranged on the upper side of the concrete layer.

[0010] By adopting the above technical solution, the frame columns and beams form a frame structure in the anti-settlement range of the outer ground, which has good bearing capacity. On the one hand, it significantly reduces the settlement difference between the main structure and the outer ground, reduces the cracking and collapse of the ground, and improves the quality of building products; on the other hand, the frame structure can be used as an outdoor scaffolding foundation, saving the cost of the scaffolding foundation, with good flatness, and reasonably and effectively reducing the construction cost.

[0011] In a second aspect, the present application provides a construction method for a ground anti-settlement structure surrounding a building, which adopts the following technical solution:

[0012] A construction process for a ground anti-settlement structure surrounding a building, comprising the following steps:

[0013] The first step is to plant reinforcement on the crown beam of the foundation pit support pile, then set up the column formwork, and cast it into frame columns;

[0014] The second step is to backfill the working surface to the bottom of the beam and slab within the ground settlement prevention range;

[0015] The third step is to plant reinforcement on the side walls of the basement, then set up the beam and slab formwork, and pour the concrete to form the beam and slab;

[0016] The fourth step is to backfill the upper side of the beam and slab with concrete to the preset elevation, and then carry out the outdoor ground surface construction.

[0017] By adopting the above technical solutions, the construction difficulty and cost are moderate, meeting the project requirements.

[0018] Optionally, a settlement joint can be reserved at the boundary of the ground anti-settlement range, and silicone structural adhesive can be used to fill the settlement joint 30 days after the construction is completed.

[0019] By adopting the above technical solution, the settlement difference generated at the connection between the outer ground anti-settlement range and the ground without measures is processed to ensure aesthetics.

[0020] Optionally, P6 impermeable concrete is used to cast beams, slabs and frame columns.

[0021] Optionally, structural adhesive is applied at the junction of the beam slab and the basement side wall using a gluing device.

[0022] By adopting the above technical solution, the waterproofness of the basement side wall is affected to a certain extent after the reinforcement is planted, so this is a repair measure.

[0023] Optionally, the gluing device includes a gluing trolley, an electric glue gun obliquely inserted into the gluing trolley, and a push handle hinged to the gluing trolley;

[0024] The push handle includes a rotating part, a connecting rod connected to the rotating part, and a grip bar connected to the connecting rod. The middle part of the rotating part is hinged to the glue trolley through a hinge rod, and the end of the rotating part away from the connecting rod is connected to a pressing bar facing the switch button of the electric glue gun.

[0025] By adopting the above technical solution, the electric glue gun is installed with the glue barrel and then inserted obliquely into the gluing trolley, and then the gluing trolley is placed at the junction of the beam and the side wall of the basement. After holding the push handle, a person presses down the grip bar slightly, so that the pressing bar is lifted and the switch of the electric glue gun is pressed. At the same time, the gluing trolley is moved along the side wall of the basement, so that the structural glue is evenly applied at the junction of the beam and the side wall of the basement.

[0026] Due to the long distance of gluing, if construction workers directly use a glue gun to apply glue, they will be easily tired when bending over for a long time, resulting in uneven gluing and affecting the quality and efficiency of gluing. In contrast, the gluing device of the present application is suitable for gluing at the junction of beams and basement side walls. During the construction process, people do not need to bend over for a long time to apply glue, ensuring the quality of gluing and high efficiency.

[0027] Optionally, the gluing trolley includes a frame and wheels rotatably connected to the frame, and an inclined sleeve is fixedly connected to one side of the frame, and the sleeve is passed through the glue outlet end of the electric glue gun, and a limiting part is connected to the outer side of the sleeve, and the limiting part includes a limiting rod abutting against the handle end of the electric glue gun, and the end of the limiting rod away from the sleeve is connected to a U-shaped portion, and an anti-slip rod is slid through the side of the U-shaped portion away from the limiting rod, and the anti-slip rod abuts against the side of the handle end of the electric glue gun away from the limiting rod.

[0028] By adopting the above technical solution, after the electric glue gun is inserted along the sleeve, the anti-slip rod is inserted into the U-shaped part, so that the electric glue gun can be fixed, and the electric glue gun is easy to disassemble and assemble.

[0029] Optionally, a limiting component is further included, wherein a connecting shaft is connected between the two wheels, a gear is fixedly sleeved on the connecting shaft, and an extension bar is connected to the end of the rotating part away from the connecting rod;

[0030] The limiting component includes a rack engaged with the upper side of the gear, a lifting frame connected to the upper side of the rack, and a limiting frame connected to the frame. The rack is passed through the limiting frame and can slide up and down. A spring is connected between the top wall of the limiting frame and the rack, and the extension bar abuts against the top wall of the lifting frame.

[0031] By adopting the above technical solution, after the push handle is pressed, the pressing bar and the extension bar both rotate upward, and the extension bar lifts the lifting frame upward, so that the rack overcomes the spring force and moves upward, thereby separating the rack from the gear and allowing the wheel to rotate.

[0032] On the one hand, since the spring has a downward squeezing force on the rack, the rack can be engaged with the gear, and the gear is restricted and cannot rotate, so the gluing trolley is not easy to move, avoiding the gluing trolley being blown away by the wind on the construction site; on the other hand, due to the force of the spring, the lifting frame will maintain the position of the extension bar, so that the push handle remains in position without human action, and will not rotate due to its own gravity to the pressing bar to accidentally start the electric glue gun.

[0033] Optionally, the lifting frame is rotatably connected to the rack.

[0034] By adopting the above technical solution, when the electric glue gun needs to be disassembled after using up the glue, the rotating part will interfere with the removal of the electric glue gun. At this time, one hand holds the push handle, and the other hand lifts the lifting frame and rotates it away from the rotating part to disengage from the extension bar. At this time, the push handle can be further rotated downward without interfering with the removal of the electric glue gun from the sleeve.

[0035] Optionally, the top of the frame is rotatably connected to side wheels, and the side wheels are used to abut against the side walls of the basement.

[0036] By adopting the above technical solution, friction is reduced, the caulking trolley is facilitated to move along the side wall of the basement, and the accuracy of the caulking position is ensured.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. This application uses frame columns and beams to form a frame structure within the perimeter of the anti-settlement range of the ground, significantly reducing the settlement difference between the main structure and the surrounding ground, and reducing ground cracking and collapse. After statistics on quality defects such as cracking, separation of the ground surface from the main building, and ground collapse in the surrounding areas of projects that have been completed and put into use for one to two years, the pass rate reached 96.7%, significantly higher than the original pass rate of 68.5%;

[0039] 2. The frame structure has been verified for its scaffolding foundation bearing capacity and can be used as an outdoor scaffolding foundation during construction, saving the cost of the scaffolding foundation and meeting the requirements of economy and practicality.

[0048] The following is combined with Figure 1-7 This application is described in further detail.

[0049] The embodiments of the present application disclose a ground anti-settlement structure for the periphery of a building and a construction method.

[0050] Reference Figure 1 The anti-settlement structure of the ground outside the building is based on the basement and foundation pit support. The beam slab 1 and frame column 2 are constructed to form a frame structure, which can withstand a large load and significantly improve the settlement difference problem between the outer ground and the main body of the building.

[0051] The frame columns 2 are arranged vertically and fixedly connected to the crown beam at the top of the foundation pit at intervals. Column steel bars 21 are arranged inside the frame columns 2, and the lower ends of the column steel bars 21 are fixed in the crown beam by planting bars.

[0052] The beam slab 1 is arranged in the horizontal direction and fixedly connected to the outer wall of the basement. Beam steel bars 11 are arranged inside the beam slab 1 and are fixed to the side wall of the basement by embedding reinforcement.

[0053] A backfill area 3 is located beneath the beam-slab 1. This backfill area 3 is formed by compacting backfill soil layer by layer. A concrete layer 4, cast from C20 plain concrete, is located above the beam-slab 1. A surface layer 5 is located above this concrete layer 4. This surface layer 5 can be one or more layers, made of various common materials depending on the project requirements.

[0054] It should be noted that the anti-settlement structure of the embodiment of the present application can not only improve the cracking and collapse of the ground, but also serve as the foundation of an outdoor scaffolding, saving costs.

[0055] A construction process for a ground anti-settlement structure surrounding a building, comprising the following steps:

[0056] The first step is to position and lay out the perimeter of the main building according to the plan layout of the scaffolding foundation. Based on the positioning and laying out, rebar is planted on the crown beams of the original structure used for the basement foundation pit support piles. Column formwork is then erected and poured with P6 impermeable concrete to form frame columns 2.

[0057] The second step is to backfill the working surface to the bottom of the beam slab 1 within the ground settlement prevention range;

[0058] The third step is to plant reinforcement on the side wall of the basement, then set up the beam slab 1 formwork, set up a post-casting strip every 55m along the anti-settlement frame range, and use P6 anti-seepage concrete to pour to form the beam slab 1. After the concrete strength reaches the required level, the formwork is removed and cured for 14 days. Structural adhesive is applied at the junction of the upper side of the beam slab 1 and the side wall of the basement using the glue device 7;

[0059] In the fourth step, backfill concrete on the upper side of the beam slab 1 to the preset elevation to form a concrete layer 4, and then construct the outdoor ground surface layer 5. Reserve a 20mm wide settlement joint 6 at the boundary of the ground anti-settlement range. 30 days after the construction is completed, the ground settlement in the anti-settlement range will stabilize, and then use silicone structural adhesive to fill the settlement joint 6.

[0060] It should be noted that the quality of rebar planting is strictly controlled according to the following rebar planting process: line positioning, drilling, hole washing, glue injection, rebar planting, curing and maintenance, and pull-out test.

[0061] In order to facilitate the gluing process, the embodiment of the present application also provides a gluing device 7 modified based on the electric glue gun 72, which adopts the form of a cart to automatically gluing while moving, and the gluing is fast and of high quality.

[0062] Reference Figure 2 The gluing device 7 includes a gluing trolley 71, an electric glue gun 72 obliquely inserted on the gluing trolley 71, and a hand push handle 73 hinged to the gluing trolley 71. The hand push handle 73 controls the switch of the electric glue gun 72 and drives the gluing trolley 71 to move. The structure is simple and easy to modify.

[0063] Specifically, the electric glue gun 72 is driven by a motor, which drives the push rod through the gear 715, thereby extruding the structural adhesive from the glue outlet to achieve the glue application function. The electric glue gun 72 has a glue outlet at one end and a handle at the other. A switch button is located at the handle. Pressing the switch activates the electric glue gun 72 to apply glue, and releasing the switch turns the electric glue gun 72 off to stop applying glue. It should be noted that the electric glue gun 72 is a prior art and commercially available, and its specific structure will not be described in detail here.

[0064] Reference Figure 2 、 Figure 3 The gluing trolley 71 includes a frame 711, wheels 712, and side wheels 716. Four wheels 712 are provided and are symmetrically mounted on opposite sides of the frame 711. The side wheels 716 are rotatably mounted on the top of the frame 711 with their axis arranged vertically. A sleeve 713 is fixedly connected to the inner wall of one end of the frame 711 near the side wheels 716. The sleeve 713 is tilted. An opening corresponding to the sleeve 713 is provided on the side of the frame 711. After the glue outlet end of the electric glue gun 72 is obliquely inserted into the sleeve 713 from top to bottom, it can be passed out from the side of the frame 711. When gluing, the side wheels 716 are pressed against the side wall of the basement, and the wheels 712 are placed on the upper surface of the beam slab 1. At this time, the glue outlet end of the electric glue gun 72 is facing the junction of the beam slab 1 and the side wall of the basement. Gluing can be achieved by starting the electric glue gun 72 and controlling the movement of the gluing trolley 71.

[0065] Reference Figure 2 、 Figure 3 In order to facilitate the control of the opening and closing of the electric glue gun 72, the push handle 73 includes a rotating part 731, a connecting rod 732 connected to the rotating part 731, and a grip bar 733 connected to the connecting rod 732. The rotating part 731 is V-shaped and the middle part is hinged to the end of the frame 711 away from the side wheel 716 through a hinge rod 74. One end of the rotating part 731 is fixedly connected to a pressing bar 734 facing the switch button of the electric glue gun 72, and the other end is fixedly connected to the connecting rod 732. The grip bar 733 is vertically fixedly connected to the end of the connecting rod 732 away from the rotating part 731. In the embodiment of the present application, the grip bar 733 is a fixed length, and in other embodiments, a telescopic structure can be adopted to adapt to the heights of different construction workers.

[0066] After a person holds the grip bar 733 and presses down the grip bar 733 , the pressing bar 734 rotates upward to press the switch, thereby activating the electric glue gun 72 .

[0067] Reference Figure 3 、 Figure 4An extension bar 735 is fixedly connected to the middle part of the side of the rotating part 731 away from the connecting rod 732, and a limiting component 76 is provided on the lower side of the extension bar 735. The position of the extension bar 735 is limited by the limiting component 76, thereby limiting the position of the push handle 73 to prevent the push handle 73 from moving accidentally.

[0068] Reference Figure 5 The outer wall of the sleeve 713 is fixedly connected to the limiting member 75, and the limiting member 75 includes a limiting rod 751, a U-shaped portion 752 and an anti-slip rod 753. One end of the limiting rod 751 is fixedly connected to the side of the sleeve 713 facing away from the side wheel 716, and the other end is used to abut the handle end of the electric glue gun 72. The U-shaped portion 752 is fixedly connected to the end of the limiting rod 751 away from the sleeve 713 and the opening is facing away from the sleeve 713. When the electric glue gun 72 is inserted into the sleeve 713, it is restricted by the limiting rod 751 and cannot be over-inserted, thereby ensuring that the glue discharge position is stable. The U-shaped portion 752 also restricts both sides of the handle end of the electric glue gun 72 to ensure that the pressing bar 734 is facing the switch. The anti-slip rod 753 is slidably arranged on the side of the U-shaped portion 752 away from the limiting rod 751. After the electric glue gun 72 is installed, the anti-slip rod 753 is inserted into the U-shaped portion 752, so that the anti-slip rod 753 can be abutted against the side of the handle end of the electric glue gun 72 away from the limiting rod 751, thereby fixing the position of the electric glue gun 72 relative to the glue trolley 71 and making it difficult to move.

[0069] Reference Figure 6 、 Figure 7 A connecting shaft 714 is fixedly connected between the two wheels 712, and a gear 715 is fixedly sleeved on the connecting shaft 714. The gear 715 is used to cooperate with the limiting component 76 to control the movement or fixation of the glue trolley 71.

[0070] Reference Figure 6 、 Figure 7 The limiting assembly 76 includes a rack 761, a lifting frame 762, a limiting bracket 763, and a spring 764. The rack 761 is located above the two gears 715. The lower sides of the rack 761 have teeth for engaging with the gears 715. When the rack 761 is moved downward to engage with the gears 715, the wheel 712 cannot rotate. When the rack 761 is moved upward to disengage the gears 715, the wheel 712 can rotate.

[0071] Two limiting frames 763 are provided and fixedly installed inside the vehicle frame 711. The rack 761 is inserted into the limiting frames 763 and is slidably connected relative to the limiting frames 763, so that the rack 761 can slide up and down along the limiting frames 763. When the rack 761 contacts the inner wall of the lower end of the limiting frame 763, the rack 761 engages with the gear 715. A spring 764 is fixedly connected between the inner top wall of the limiting frame 763 and the rack 761, and the spring 764 applies a thrust to the rack 761. The upper end of the middle part of the rack 761 is rotatably connected to the lifting frame 762, and the lifting frame 762 is U-shaped. Two extension bars 735 extend into the lifting frame 762, and the upper side of the extension bar 735 contacts the inner top wall of the lifting frame 762.

[0072] It should be noted that the gluing trolley 71 in the embodiment of the present application is a hand-push type. In other embodiments, the gluing trolley 71 can also be an electric drive type. The gluing trolley 71 is controlled by a motor to move at a constant speed. The construction worker gently holds the hand-push handle 73 and keeps the side wheels 716 against the side wall of the basement.

[0073] The implementation principle of the glue-spraying device in the embodiment of the present application is as follows:

[0074] In the first step, the electric glue gun 72 is installed with the glue cartridge and then obliquely inserted into the sleeve 713, and then the anti-drop rod 753 is inserted into the U-shaped portion 752 to fix the position of the electric glue gun 72;

[0075] The second step is to place the glue trolley 71 at the junction of the beam slab 1 and the basement side wall, and press the side wheels 716 against the basement side wall;

[0076] In the third step, the user grasps the push handle 73 and slightly depresses the grip bar 733, causing the pressing bar 734 to rise and depress the switch of the electric glue gun 72. At the same time, the extension bars 735 rotate upward, which in turn lifts the lifting frame 762, causing the rack 761 to overcome the force of the spring 764 and move upward, thereby separating the rack 761 from the gear 715, and the wheel 712 can rotate.

[0077] Step 4: Move the glue-spreading trolley 71 along the side wall of the basement so that the structural glue is evenly applied to the junction of the beam slab 1 and the side wall of the basement;

[0078] Step 5. After the electric glue gun 72 has used up all the glue, first remove the anti-drop rod 753, then hold the push handle 73 with one hand, and lift the lifting frame 762 with the other hand, then rotate it away from the rotating part 731 until it is out of the extension bar 735. At this time, the push handle 73 can be further rotated downward. Finally, take out the electric glue gun 72 and install a new glue cartridge.

[0079] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
