Description

Technical Field

[0001] The invention relates to the field of building construction equipment, and in particular to a fast-assembly type building construction device. Background Art

[0002] Rapid assembly type building refers to the building obtained by directly splicing and assembling prefabricated building modules, which has the advantages of fast construction speed and low construction cost. In the construction process of rapid assembly type building, it is necessary to nail the support base for supporting the prefabricated building modules on the ground, such as the assembled building support base described in patent CN214883628U, which is mainly composed of support plates, cone nails and oblique nails built into the cone nails. After the building support base described in the patent is nailed to the ground, the oblique nails built into the cone nails are locked into the ground, and the fast assembly type building support base can be firmly installed.

[0003] During the installation and construction process of the building support base described in the above patent, due to the large size of the cone nails of the building support base, it is difficult to directly hammer them down on the hard ground, and it is also difficult to directly lock the oblique nails in the cone nails into the ground. It is necessary to drill anchor holes in the ground in advance before the cone nails can be successfully hammered into the anchor holes, and it is also necessary to drill oblique holes required for the oblique nails in the anchor holes. The overall operation steps are cumbersome, which is not conducive to the rapid installation of the building support base.

[0004] In addition, since the diameter of the drilled anchor hole needs to be smaller than the outer diameter of the cone nail, it is difficult to accurately control the adjustment of the drilling angle and the drilling height, as well as the control of the drilling size during the process of further drilling the inclined hole required for the corresponding position of the inclined nail in the anchor hole. As a result, the drilled inclined hole cannot perfectly fit the inclined nail built into the cone nail, thereby affecting the installation stability of the entire building support seat. Summary of the invention

[0005] In order to overcome the shortcomings that the overall installation steps of the building support seat are complicated and the drilling accuracy of the inclined holes during the installation of the building support seat is difficult to control, which affects the installation stability of the building support seat, the present invention provides a quick-assembly building construction device.

DETAILED DESCRIPTION

[0032] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0033] Example 1

[0034] A fast-assembly building construction device, such as Figure 1-Figure 10As shown, it includes a mounting frame 1, a supporting slider 21, a drill rod 31, a transverse slider 51, a lifting cylinder 61, a bushing 63, an insert block 64, a fourth spring 65 and an elastic punching piece; the upper end of the mounting frame 1 is bolted with a handle 11; the bottom of the mounting frame 1 is slidably connected to two supporting sliders 21; a first spring 22 is fixedly connected between the two supporting sliders 21 and the mounting frame 1; the lower side of the mounting frame 1 is rotatably connected to the drill rod 31; the internal bolts of the mounting frame 1 are connected to the motor 4 that drives the drill rod 31 to rotate; the mounting frame 1 is directly pressed down to push the drill rod 31 to drill anchor holes in the ground; the rear sides of the two supporting sliders 21 are slidably connected with a transverse slider 51; a second spring 52 is fixedly connected between the transverse slider 51 and the two supporting sliders 21; the middle part of the transverse slider 51 is slidably connected to the lifting cylinder 61; the lower side of the lifting cylinder 61 is provided with two elastic punching pieces, two The elastic punching members are all arranged in an inclined state with one end facing downward away from the center of the lifting cylinder 61; a third spring 62 is fixedly connected between the lifting cylinder 61 and the horizontal slider 51; a bushing 63 is rotatably connected to the upper side of the lifting cylinder 61; an insert block 64 is slidably connected to the inside of the bushing 63 through a spline; a plurality of impact strips 642 are welded to the lower side of the outer surface of the insert block 64, and the insert block 64 intermittently impacts the elastic punching member through the impact strips 642; a plurality of clamping strips 641 in a circumferential array are arranged inside the insert block 64; after the horizontal slider 51 is pushed to drive the insert block 64 to align below the drill rod 31, the drill rod 31 is clamped on the clamping strip 641 through the clamping groove 311 provided at the bottom, driving the insert block 64 and the bushing 63 connected thereto to rotate rapidly, and at the same time, the drill rod 31 pushes the insert block 64 to drive the impact strip 642 to continuously impact the elastic punching member; a fourth spring 65 is fixedly connected between the insert block 64 and the bushing 63.

[0035] like Figure 7 and Fig.10 As shown, the elastic punching member includes a punching column 71, a seventh spring 72, a collision block 73 and a buffer washer 74; the lower side of the lifting cylinder 61 is slidably connected with the punching column 71, and the punching column 71 is set to be in an inclined state downwardly away from the center of the lifting cylinder 61, and the upper end of the punching column 71 faces the plug block 64; the seventh spring 72 is fixed between the punching column 71 and the lifting cylinder 61; the upper end of the punching column 71 is slidably connected with the collision block 73, and the upper end of the collision block 73 is set to be semi-ellipsoidal; a circle of buffer washers 74 is sleeved between the collision block 73 and the punching column 71, and the buffer washers 7 4 is made of elastic rubber material. When the collision block 73 receives the rotational impact force from the impact bar 642, the impact force received by the collision block 73 is divided into a lateral impact force in the same direction as the rotation of the impact bar 642 and a longitudinal impact force in the movement of the collision block 73 along the punching column 71. In this process, the buffer gasket 74 absorbs part of the lateral impact force transmitted by the collision block 73 to the punching column 71, effectively providing a buffering protection for the punching column 71. The impact bars 642 are all set to be ellipses inclined in the up-down direction, and the impact bars 642 impact the collision block 73 through the arc surfaces on both sides.

[0036] like Figure 4 As shown, two vertical plates 53 are welded to the upper side of the transverse slider 51 ; a kick plate 54 is welded between the rear sides of the two vertical plates 53 , and the transverse slider 51 can be easily pushed toward the supporting slider 21 by simply kicking the kick plate 54 .

[0037] like Figure 8 and Fig. 9 As shown, the outer surface of the plug block 64 is provided with a plurality of hooking members in a circumferential array. After the plug block 64 knocks the elastic punching member into the ground, the elastic punching member is hooked upward by the hooking members to prevent the elastic punching member from being stuck in the ground and unable to rebound normally. The hooking members are composed of a spring piece 66 and a fifth spring 67; the outer surface of the plug block 64 is welded with a circumferential array of spring pieces 66, and the lower ends of the spring pieces 66 are all provided with inverted hooks; a fifth spring 67 is fixedly connected between the spring piece 66 and the plug block 64; the spring piece 66 is located between two adjacent impact bars 642, and the outward protrusion height of the spring piece 66 is lower than the outward protrusion height of the two impact bars 642 to prevent the rotating spring piece 66 from colliding with the elastic punching member.

[0038] The anchor hole setting work of this fast assembly type building construction device:

[0039] First, the operator holds the handle 11 to move the quick-assembled construction device to the top of the ground to be drilled, and the two support slide blocks 21 are both close to the ground. Then the operator turns on the motor 4, and the output shaft of the motor 4 drives the drill rod 31 to rotate. At the same time, the operator presses down the handle 11 to push the mounting frame 1 to move downward along the support slide block 21. The mounting frame 1 compresses the first spring 22 downward, allowing the mounting frame 1 to push the drill rod 31 to drill an anchor hole downward on the ground. The diameter of the drilled anchor hole is smaller than the outer diameter of the cone nail of the building support seat 8.

[0040] Afterwards, the operator lifts the handle 11, and the compressed first spring 22 pushes the mounting frame 1 to return upward along the supporting slide block 21, thereby completing the anchor hole drilling work.

[0041] The inclined hole setting work of this fast assembled building construction device:

[0042] like Fig.11 As shown, the conical nails at the bottom of the building support seat 8 are provided with oblique nails, and oblique holes corresponding to the oblique nails need to be drilled in the anchor holes.

[0043] After completing the anchor hole drilling work, the operator kicks the kick plate 54 to push the horizontal slider 51 and the vertical plate 53 forward, and the horizontal slider 51 pushes the second spring 52 to compress forward until the horizontal slider 51 drives the lifting cylinder 61, the bushing 63 and the plug block 64 to move to the bottom of the drill rod 31. At this time, the lifting cylinder 61 is aligned with the top of the drilled anchor hole. Then the operator presses down the handle 11 again to push the mounting frame 1 to move downward along the supporting slider 21. The mounting frame 1 pushes the drill rod 31 downward, so that the slot 311 of the drill rod 31 is stuck on the clamping strip 641 of the plug block 64, so that the lower end of the drill rod 31 is combined with the plug block 64 into a complete structure.

[0044] Then the operator continues to press down the handle 11 to push the mounting frame 1 to move downward along the supporting slider 21, and pushes the insert block 64 through the drill rod 31 to drive the lifting cylinder 61 to move downward along the transverse slider 51, so that the lifting cylinder 61 moves downward into the anchor hole, and the lifting cylinder 61 drives the third spring 62 to compress downward until the lifting cylinder 61 moving downward is blocked by the transverse slider 51, and the lifting cylinder 61 stops moving downward. At this time, the lower end of the drilling column 71 is aligned with the position where the inclined hole needs to be drilled in the anchor hole.

[0045] After that, the operator turns on the motor 4, and the output shaft of the motor 4 drives the drill rod 31 to rotate, and the drill rod 31 drives the plug block 64 and the bushing 63 connected thereto to rotate rapidly. At the same time, the operator slowly presses down the handle 11 to push the mounting frame 1 to continue to move downward along the supporting slider 21, and the drill rod 31 drives the plug block 64 to move downward along the bushing 63, and the plug block 64 drives the fourth spring 65 to compress downward, and at the same time, the plug block 64 drives the impact bar 642 to continuously knock the impact block 73 during the rotation process, and by knocking the impact block 73, the punching column 71 is pushed to move obliquely downward along the lifting cylinder 61, and the punching column 71 drives the seventh spring 72 to compress downward, so that the punching column 71 can drill the required oblique hole in the anchor hole under the impact force of the impact block 73, thereby completing the oblique hole drilling work.

[0046] During the process of the impact bar 642 striking the impact block 73, the impact thrust generated by the rotating impact bar 642 on the impact block 73 is divided into a lateral impact force in the same direction as the rotation direction of the impact bar 642, and a longitudinal impact force in the same direction as the movement of the impact block 73 along the punching column 71. After the impact block 73 is subjected to the impact force from the impact bar 642, the impact block 73 transmits the impact force to the punching column 71. In the process, part of the lateral impact force which is different from the punching movement direction of the punching column 71 is absorbed by the buffer gasket 74, thereby preventing the punching column 71 from being bent and damaged due to long-term lateral impact force.

[0047] Even if a plurality of oblique nails are arranged inside the conical nails of the building support seat 8, as long as the same number of elastic punching members as the oblique nails are arranged inside the lifting cylinder 61, the punching work of the plurality of oblique holes can be completed synchronously with high precision.

[0048] After completing the drilling of the inclined hole, the operator turns off the motor and lifts the handle 11. The compressed first spring 22 pushes the mounting frame 1 to return upward along the supporting slide block 21. At the same time, the compressed fourth spring 65 pushes the plug block 64 to return upward. When the plug block 64 leaves the punching column 71, the compressed seventh spring 72 pushes the punching column 71 to pop out of the inclined hole. If the punching column 71 cannot be ejected from the inclined hole smoothly, the operator presses down the handle 11 and pushes the plug block 64 downward through the drill rod 31. When the plug block 64 drives the spring piece 66 downward to pass through the collision block 73, the spring piece 66 is blocked by the collision block 73 and drives the fifth spring 67 to stretch upward. The spring piece 66 flips up and is smoothly moved downward to the collision block 73. At the bottom, the stretched fifth spring 67 flips the spring piece 66 downward and resets it, and then the operator lifts the handle 11 upward again. During this process, the insert block 64 applies an upward pulling force to the collision block 73 through the inverted hook of the spring piece 66, so that the punching column 71 clamped in the inclined hole is loosened under the action of the upward lifting force. After that, since the punching column 71 cannot move directly vertically upward under the pulling force of the spring piece 66, the upward moving spring piece 6 will be blocked by the punching column 71, so that the upward moving spring piece 66 is blocked by the collision block 73 and drives the fifth spring 67 to compress again, so that the spring piece 66 can smoothly leave the collision block 73 upward, and at the same time, the compressed third spring 62 pushes the lifting cylinder 61 to reset upward.

[0049] Finally, the operator releases the kick plate 54, and the compressed second spring 52 pushes the transverse slider 51 and the vertical plate 53 to pop back and reset.

[0050] Example 2

[0051] This embodiment is a further optimization based on embodiment 1. Figure 7 As shown, it also includes a block 68 and a sixth spring 69; a plurality of blocks 68 arranged up and down are slidably connected to the left and right sides of the bushing 63; a sixth spring 69 is fixedly connected between each block 68 and the bushing 63; a plurality of grooves 643 adapted to the block 68 are provided on the upper side of the outer surface of the insert block 64, and when the insert block 64 passes through the block 68, the insert block 64 will be subjected to elastic resistance from the sixth spring 69.

[0052] As the operator continues to press down on the handle 11 to push the mounting frame 1 to move downward along the support slide block 21, the drill rod 31 pushes the plug block 64 to move downward along the bushing 63. Every time the plug block 64 passes a block 68, it pushes the block 68 to drive the sixth spring 69 to be compressed into the bushing 63, forming a resistance to the operator when pressing down on the handle 11. After the block 68 aligns with the groove 643 of the plug block 64, the compressed sixth spring 69 pushes the block 68 to pop outward and sink into the corresponding groove 643. The resistance to the operator pressing down on the handle 11 suddenly decreases. As the operator presses down on the handle 11 to allow the plug block 64 to pass more blocks 68 downward, the number of blocks 68 and the number of compressed sixth springs 69 pushed by the plug block 64 at the same time also increases. The greater the resistance the operator encounters when pushing the handle 11 downward, the greater the resistance the operator encounters. Subsequently, when each block 68 is aligned with the corresponding groove 643 of the plug block 64, the multiple sixth springs 69 respectively drive the block 68 to pop out into each groove 643, and the magnitude of the sudden decrease in resistance encountered by the operator when pressing down the handle 11 also increases. In the process of continuously pressing down the handle 11, the operator can clearly sense each time the plug block 64 passes through the block 68 downward through the feedback of the gradient-increasing resistance change, thereby helping the operator to judge the current pressing depth of the plug block 64 and facilitating the operator to adjust the pressing speed of the plug block 64, thereby preventing the operator from pressing down the plug block 64 too quickly, causing the impact bar 642 to hit the impact block 73 with excessive force, thereby causing severe wear thereof.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
