Description

Technical Field

[0001] The utility model relates to the technical field of house construction, in particular to a steel positioning device for SMW method piles. Background Art

[0002] Foundation pit support is a necessary guarantee for the construction of the main structure of the basement. As a temporary project, the foundation pit project must not only meet the basic requirements of safety and stability, but also pursue low cost, energy saving and environmental protection. SMW piles are an important foundation pit support measure in soft soil areas, which can not only support the soil pressure, but also prevent soil erosion.

[0003] The SMW method was introduced in Japan in 1976. It uses a multi-axis drilling and mixing machine to drill to a certain depth on site. At the same time, a cement-based strengthening agent is sprayed at the drill bit to repeatedly mix and stir with the foundation soil. Overlapping construction is adopted between each construction unit. Then, H-shaped steel or steel plates are inserted as stress reinforcement materials before the cement-soil mixture hardens. When the cement hardens, an underground pile structure with a certain strength and rigidity is formed. The continuously connected underground piles can be seamlessly combined into an underground wall structure.

[0004] In the SMW pile construction, when the steel is inserted, the steel positioning card is used to position the steel to ensure the accuracy of the plane position of the steel during the insertion process, and to prevent the plane position deviation from the mechanical vibration during the steel insertion process. The common steel positioning cards on the construction site are composed of four square wood or square guide steel pipes. The steel positioning card is reinforced with square wood or welded and fixed with square steel pipes to form a card. However, due to the rough workmanship of the steel positioning card, it is impossible to achieve horizontal layout, which affects the verticality of the steel insertion, and it is also impossible to ensure the precise positioning of the steel, which results in the spacing of the steel failing to meet the construction requirements and the work quality is not high.

[0041] like Figure 1-Figure 6As shown, this embodiment provides a steel section positioning device for SMW construction method piles, which includes a transverse frame 1, a support mechanism 2, a longitudinal frame 3, a locking member 4 and a claw mechanism 5. The transverse frame 1 extends along a first direction and is provided with a scale line 11 along the first direction. The support mechanism 2 includes a support driver 21, and the support driver 21 can adjust the horizontality of the transverse frame 1. The longitudinal frame 3 is slidably arranged on the transverse frame 1 along the first direction. The locking member 4 can lock the longitudinal frame 3 on the transverse frame 1. The claw mechanism 5 is arranged on the longitudinal frame 3 for positioning the steel section.

[0042] In this embodiment, the transverse frame 1 extends along the first direction and is provided with a scale line 11 along the first direction. The longitudinal frame 3 is slidably arranged on the transverse frame 1 along the first direction, so that the construction personnel can quickly and accurately adjust the position of the longitudinal frame 3 according to actual needs, thereby realizing the precise positioning of the steel section. The support mechanism 2 includes a support driver 21, which can adjust the horizontality of the transverse frame 1 to ensure that the positioning device can maintain horizontal stability under different terrains and construction environments, thereby improving the accuracy of the positioning of the steel section. The locking member 4 can lock the longitudinal frame 3 on the transverse frame 1, ensuring the stability of the longitudinal frame 3 after locking, preventing it from shifting its position during the construction process, thereby affecting the positioning of the steel section. The claw mechanism 5 is arranged on the longitudinal frame 3, which is used to position the steel section, further improving the accuracy of the positioning of the steel section, and ensuring the stability and verticality of the steel section during the insertion process. Through the above-mentioned arrangement, the steel section positioning device for SMW construction method piles in this embodiment can realize the precise positioning of the steel section, and ensure the operation quality of the steel section being inserted into the SMW construction method pile.

[0043] Specifically, Figure 1 As shown, the support mechanism 2 also includes a bearing seat 22, and a plurality of support drivers 21 are provided. The plurality of support drivers 21 are arranged on the bearing seat 22 at intervals along the first direction. The output end of the support driver 21 is connected to the transverse frame 1, and can drive the transverse frame 1 to move in the vertical direction. By providing the bearing seat 22, not only can the stable operation of the support driver 21 be ensured, but also the weight from the transverse frame 1 and the steel section can be dispersed and borne, thereby improving the bearing capacity and stability of the entire positioning device. By arranging the plurality of support drivers 21 at intervals along the first direction, the supporting capacity and stability of the positioning device are further enhanced. By driving the transverse frame 1 to move in the vertical direction through the support driver 21, the transverse frame 1 can maintain a horizontal state, ensuring the verticality of the steel section when being inserted, and improving the operation quality.

[0044] Specifically, Figure 1-Figure 4As shown, a groove 12 is provided on the transverse frame 1, and the groove 12 is arranged through along the first direction. The output end of the support driver 21 extends into the groove 12 and is detachably connected to the transverse frame 1, which can ensure that when the support driver 21 drives the transverse frame 1 to move in the vertical direction, the connection between the two is stable and reliable, and is not prone to loosening or falling off. At the same time, the through setting of the groove 12 also facilitates the installation and removal of the support driver 21, thereby improving the construction efficiency.

[0045] More specifically, if Figure 4 As shown, a protrusion 121 is provided on the inner wall of the groove 12, and the output end of the support driver 21 is snapped into the protrusion 121. By providing the protrusion 121, an additional support and fixing point is provided for the installation of the support driver 21, and the connection stability and reliability between the support driver 21 and the transverse frame 1 are further enhanced, which can effectively prevent the loosening or falling off of the components due to external force or vibration during the construction process. In this embodiment, the protrusion 121 includes two protrusions, and the two protrusions are respectively arranged on the inner side wall of the groove 12 facing each other to ensure the connection effect of each component. In other embodiments, the protrusion 121 includes a clamping strip, which is arranged in the groove 12 along the first direction and is snapped with the output end of the support driver 21, that is, the specific structure of the protrusion 121 is not limited, as long as the above-mentioned functional role can be achieved.

[0046] It should be noted that the support driver 21 of the present embodiment may adopt other specific structures such as a cylinder or a hydraulic cylinder, as long as it is convenient for adjusting the horizontality of the transverse frame 1, and no excessive limitation is made here.

[0047] Specifically, Figure 1-Figure 3 As shown, the transverse frame 1 includes two first frames 13 that are parallel to each other and spaced apart, thereby forming a stable support structure that can effectively bear the weight of the steel section and the longitudinal frame 3. A slide groove 131 is provided on the first frame 13, and the longitudinal frame 3 is arranged between the two first frames 13 and connected to the slide groove 131 in a sliding manner along a first direction. By providing the slide groove 131, the sliding of the longitudinal frame 3 is made more stable to avoid deviation or shaking. At the same time, it is also convenient for operators to adjust the position of the longitudinal frame 3 relative to the transverse frame 1 to meet the positioning requirements of the steel section.

[0048] More specifically, if Figure 1-Figure 3As shown, the locking member 4 is screwed to the longitudinal frame 3 and can abut against the inner wall of the slide slot 131, thereby effectively preventing the longitudinal frame 3 from moving in the slide slot 131. When the locking member 4 is tightened and abuts against the inner wall of the slide slot 131, the longitudinal frame 3 will be firmly locked in a predetermined position. Such a setting not only ensures the stability of the longitudinal frame 3 during the positioning process and improves the positioning effect of the steel section, but also avoids the position displacement of the longitudinal frame 3 caused by external force or vibration. Optionally, the locking member 4 can be other specific components such as screws and bolts, as long as it can achieve the above-mentioned functions, and no excessive restrictions are made here.

[0049] Specifically, Figure 1 and Figure 2 As shown, the longitudinal frame 3 includes two second frames 31 which are parallel to each other and spaced apart, and the claw mechanism 5 includes a plurality of claw heads 51 spaced apart, and each two claw heads 51 form a group, which are respectively disposed on two second frames 31 facing each other. The two second frames 31 move toward each other or away from each other, driving the claw heads 51 to move toward or away from each other to achieve the clamping and removal of the steel section. Through the above arrangement, the steel section can be firmly clamped to prevent the steel section from shaking or shifting during the insertion or positioning process. At the same time, the claw heads 51 disposed opposite to each other can also achieve bidirectional clamping of the steel section, improving the stability and reliability of the clamping. Moreover, the number and spacing of the claw heads 51 can be adjusted according to actual needs to adapt to steel sections of different specifications and sizes.

[0050] More specifically, the claw head 51 is slidably connected to the second frame body 31 to ensure that the claw head 51 can slide back and forth along the extension direction of the second frame body 31, thereby achieving the clamping and positioning of steel sections at different positions, making the operation more convenient. Figure 5 and Figure 6 As shown, a through hole is provided on the claw head 51, and a sliding rod is provided on one side of the second frame body 31. The sliding rod is slidably connected to the through hole, thereby realizing the sliding of the claw head 51 relative to the second frame body 31, making it easier for the claw head 51 to clamp the steel section.

[0051] Specifically, Figure 1-Figure 6 As shown, the claw mechanism 5 also includes an abutment 52. A through slot 511 extending vertically is provided on the claw head 51. The abutment 52 is telescopically arranged on the inner wall of the through slot 511 to abut against the steel section. During the positioning of the steel section, the abutment 52 can extend into the through slot 511, closely contact the surface of the steel section and apply a certain pressure, thereby ensuring that the steel section is firmly clamped in the claw mechanism 5. Such a setting can effectively prevent the steel section from shaking or shifting during the insertion or positioning process, thereby improving the accuracy and stability of positioning.

[0052] More specifically, if Figure 6As shown, a plurality of abutment members 52 are provided to increase the contact area with the steel section and improve the clamping effect. A plurality of abutment members 52 are arranged on the inner wall of the through slot 511 and are arranged on the inner walls of the through slot 511 on both sides facing each other. The claw mechanism 5 also includes an elastic member, and the two ends of the elastic member are respectively connected to the claw head 51 and the abutment member 52. The abutment member 52 has a tendency to move toward the through slot 511 under the support of the elastic member, so that the abutment members 52 on both sides of the inner wall of the through slot 511 have a tendency to move toward each other, so as to press against the steel section and realize the positioning of the steel section. Optionally, the elastic member adopts other specific components such as compression springs or tension springs.

[0053] Specifically, Figure 1 and Figure 2 As shown, the steel positioning device for SMW construction piles also includes an adjusting member 6, which is screwed to the two second frames 31 and can adjust the spacing between the two second frames 31, thereby adapting to the clamping and positioning of steel sections of different widths. In addition, the operator only needs to loosen or tighten the adjusting member 6 to change the spacing of the second frames 31, without the need for complicated disassembly and reinstallation, which not only improves the construction efficiency but also reduces the difficulty of operation. Moreover, by providing the adjusting member 6, the connection strength between the two second frames 31 is also improved to prevent deformation or loosening thereof. Optionally, the adjusting member 6 is made of bolts or screws to facilitate local materials, and the specific structure of the adjusting member 6 is not further limited herein.

[0054] Specifically, a level 7 is provided on both the transverse frame 1 and the longitudinal frame 3, and the operator can quickly and accurately adjust the horizontality of the transverse frame 1 and the longitudinal frame 3 according to the indication of the level 7, which is conducive to ensuring the verticality of the steel section when it is inserted. Optionally, the level 7 uses a bubble level or a digital level, which is not limited here.

[0055] The specific working process of this device is described below:

[0056] During the SMW pile construction process, the operator first measures the horizontality of the transverse frame 1 and the longitudinal frame 3 using a level meter 7. Based on the horizontal measurement result, the operator drives the transverse frame 1 to move in the vertical direction through the support driver 21, so that the transverse frame 1 and the longitudinal frame 3 can maintain a horizontal state, which is beneficial to ensure the verticality of the steel section when it is inserted. Then, the operator adjusts the spacing between the two second frames 31 according to the size of the steel used on site. First, the adjustment member 6 is screwed to separate the two second frames 31 from each other. At this time, the two second frames 31 can move independently relative to the transverse frame 1 to adjust the spacing between them. At this time, the steel is inserted between the claws 51 on the two second frames 31, and the abutment members 52 on both sides of the through groove 511 are used to tighten the steel so that the steel can be just clamped on the claws 51 to ensure the clamping effect of the claw mechanism 5 on the steel. At this time, the two second frames 31 are connected together by screwing the adjustment member 6 again, and the locking member 4 is abutted against the inner wall of the slide groove 131, thereby effectively preventing the second frame 31 from moving in the slide groove 131, avoiding the steel from being offset and affecting the positioning and insertion of the steel. Before inserting the steel each time, the operator adjusts the specific position of the longitudinal frame 3 relative to the transverse frame 1 according to the scale line 11 to ensure that the spacing between the steel after each insertion meets the construction requirements.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
