Description

Technical Field

[0001] The invention relates to the technical field of pole installation, in particular to a construction mould for erecting fence poles. Background Art

[0002] The fence includes poles and fence nets. During the construction process of the poles, the pole foundation for fixing the poles is usually formed by pouring concrete. When the above method is used for construction, concrete is usually poured in the excavated foundation pit first, and the poles are inserted when the concrete is not completely solidified. In this process, since the lower end of the pole usually does not directly penetrate the incompletely solidified concrete, when the pole remains in the incompletely solidified concrete, it will slowly slide down due to its own gravity. This slide will directly cause the elevation of the erected pole to fail to meet the engineering requirements. In addition, since the concrete will settle during the solidification process, the error in the elevation of the erected pole is further aggravated. Summary of the invention

[0044] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0045] Example 1

[0046] like Figure 1-18As shown, this embodiment provides a construction mold for erecting fence poles, which includes a mold body 100, and the mold body 100 includes two installation components; the installation component includes a baffle assembly, and a clamping plate assembly is provided above the baffle assembly; the baffle assemblies at the two installation components are used to jointly constitute a pouring groove 250 for pouring concrete, and the clamping plate assemblies at the two installation components are used to jointly constitute a limiting groove 810 for clamping the corresponding part of the pole; the baffle assembly has an L-shaped baffle 130, and the clamping plate assembly includes an L-shaped clamping plate 150; the baffle 130 is arranged parallel to the corresponding sides of the clamping plate 150, and a support assembly is arranged between the corresponding sides.

[0047] Through the arrangement of the mold body 100, the baffle plate 130, the support plate 120, the pouring groove 250, the clamping plate 150, the support assembly and the limiting groove 810 in this embodiment, when pouring the fence pier, the workers first dig a foundation pit on the ground, then splice the two baffle plates 130 to form the mold body 100 and put it into the foundation pit, then pass the vertical pole through the limiting groove 810, extend it into the limiting groove 810, clamp the vertical pole with two clamping plates 150, and then inject concrete into the pouring groove 250. Concrete fills the pouring groove 250 and wraps around one end of the vertical pole extending into the limiting groove 810. Since the center of the limiting groove 810 and the center of the pouring groove 250 are located on the same axis, the fence pole is always located at the center of the fence pier; when the staff injects concrete into the pouring groove 250, the vertical pole is fixed by the clamping plate 150, thereby better preventing the vertical pole from shifting; since the vertical pole is clamped by the clamping plate 150, it is prevented from sliding down due to gravity, thereby affecting the elevation of the vertical pole.

[0048] In this embodiment, support plates 120 matching the shape of the baffle 130 are provided at the upper and lower side walls of the baffle 130 , and the support assembly is provided between the support plate 120 and the baffle 130 .

[0049] By disposing the baffle 130 in this embodiment, one end of the support assembly is connected to the baffle 130 and the other end is connected to the support plate 120, thereby facilitating the installation of the support assembly by the staff.

[0050] In this embodiment, a plurality of fixing plates 240 are provided along the height direction between the support plates 120 located at the upper and lower ends of the baffle 130, and the plurality of fixing plates 240 are distributed at the side walls at both ends and the center of the side walls of the baffle 130; a first connecting plate 230 is provided at the side wall at one end of the baffle 130 to be in contact with the fixing plate 240 at the side wall of the other baffle 130, a first through hole 220 is provided at the center of the first connecting plate 230, and second through holes 310 corresponding to the first through holes 220 are provided on the fixing plates 240 located at both ends of the baffle 130.

[0051] By setting the fixing plate 240, the first connecting plate 230, the first through hole 220 and the second through hole 310 in this embodiment, the two ends of the fixing plate 240 are respectively welded to the end faces of the two support plates 120, thereby better improving the structural strength of the support plates 120 and preventing the support plates 120 from being bent by the support components; when splicing the baffle plates 130, the staff will pass the bolts through the first through hole 220 and the second through hole 310 to connect the two baffle plates 130, which better facilitates the staff to splice the baffle plates 130.

[0052] In this embodiment, the side walls at both ends of the clamping plate 150 are bent outward to form a second connecting plate 820 , and the side walls of the second connecting plate 820 are provided with connecting holes 830 for bolts to pass through.

[0053] By providing the second connecting plate 820 and the connecting hole 830 in this embodiment, the staff can fix the two clamping plates 150 by passing the bolts through the corresponding connecting holes 830 on the two clamping plates 150, thereby improving the clamping strength of the clamping plates 150 and preventing the vertical pole from shaking; at the same time, the vertical pole can also be suspended in the pouring groove 250 to prevent the vertical pole from contacting the ground.

[0054] In this embodiment, the support assembly includes a support rod 110, and the support rod 110 includes an arc-shaped rod 530. Adjustment mechanisms for adjusting the inclination angle of the clamping plate 150 are provided at both ends of the arc-shaped rod 530; the adjustment mechanism includes a threaded rod 410 arranged at one end of the arc-shaped rod 530 and perpendicular to the support plate 120; a third through hole 210 is provided at the support plate 120 for the threaded rod 410 to pass through, and the outer side wall of one end of the threaded rod 410 passing through the third through hole 210 expands outwardly along the circumferential direction to form a first flange 460; a first spring 450 is provided between the first flange 460 and the support plate 120 and is sleeved on the threaded rod 410; a nut 420 matching the threaded rod 410 is provided at one end of the support plate 120 away from the first spring 450;

[0055] A thin rod 520 perpendicular to the clamping plate 150 is provided at one end of the arc rod 530 away from the threaded rod 410, and a round ball 510 is provided at one end of the thin rod 520 away from the arc rod 530; a sleeve 930 for the round ball 510 and the thin rod 520 to extend into is provided on the side wall of the clamping plate 150.

[0056] By configuring the arc rod 530, the adjustment mechanism, the threaded rod 410, the third through hole 210, the first flange 460, the first spring 450, the nut 420, the thin rod 520, the ball 510 and the sleeve 930 in this embodiment, the staff can assemble the mold body 100 and put it into the excavated foundation pit. When the bottom surface of the foundation pit is inclined or there is sand and gravel, the mold body 100 will be tilted, thereby causing the vertical pole to tilt. At this time, the staff rotates the nut 420 on the support plate 120 to move the threaded rod 410 at the higher end downward. The downward movement of the threaded rod 410 drives the arc rod 530 downward, thereby driving the thin rod 520 and the ball 510 downward. The downward movement of the thin rod 520 and the ball 510 pushes the clamp 150 to rotate along the sleeve 930 at the adjacent side wall until the upper end surface of the clamp 150 is parallel to the ground, thereby ensuring that the vertical pole clamped by the clamp 150 is perpendicular to the ground, thereby better preventing the vertical pole from tilting.

[0057] In this embodiment, a first ring 430 is provided at the lower end of the nut 420 , a scale line is provided on the outer wall of the first ring 430 , and a first pointer mark 440 pointing to the scale line is provided on the side wall of the support plate 120 .

[0058] By setting the scale lines, the first ring 430 and the first pointer mark 440 in this embodiment, the staff can rotate the nut 420, thereby driving the first ring 430 to rotate together, so that the first pointer mark 440 points to different scales on the first ring 430. When it is necessary to adjust the threaded rod 410 used to a uniform height, it is only necessary to rotate different nuts 420 to make the first pointer mark 440 point to the same scale of the first ring 430, thereby making it more convenient for the staff to reset the support rod 110.

[0059] In this embodiment, a rectangular push plate 1101 is provided at the end of the splint 150 away from the sleeve 930, and guide rods 1401 passing through the support plate 120 are provided at the four corners of the rectangular push plate 1101, and a fourth through hole 850 for the guide rod 1401 to pass through is provided at the side wall of the support plate 120; the outer wall of the guide rod 1401 away from the end of the rectangular push plate 1101 expands outwardly along the circumferential direction to form a second flange 920, and a second spring 910 is provided between the second flange 920 and the support plate 120 and is sleeved on the guide rod 1401; a threaded through hole 840 is provided at the center of the side wall of the splint 150, and a bolt 1002 is provided at the threaded through hole 840 to push the rectangular push plate 1101.

[0060] Through the arrangement of the rectangular push plate 1101, the guide rod 1401, the fourth through hole 850, the second flange 920, the second spring 910, the threaded through hole 840 and the bolt 1002 in this embodiment, after the staff passes the vertical pole through the limiting groove 810, they rotate the bolt 1002 in the corresponding direction according to the inclination direction of the mold body 100, so that the bolt 1002 pushes the rectangular push plate 1101 to clamp the vertical pole; after the staff adjusts the vertical pole to be perpendicular to the ground, the staff adjusts the bolt 1002 in the corresponding direction, so that the bolt 1002 pushes the rectangular push plate 1101, and the rectangular push plate 1101 pushes the vertical pole to the center of the pouring groove 250, so that the erected vertical pole is in the same straight line, which is more convenient for the staff to install the fence net between adjacent vertical poles.

[0061] In this embodiment, a slide groove 1201 is provided along the length direction of the bolt 1002 at the outer wall of the bolt 1002; a second ring 1004 is also provided on the outer wall of the bolt 1002 and is sleeved on the bolt 1002, a sliding block 1301 is provided on the inner wall of the second ring 1004 and extends into the slide groove 1201, and a third spring 1003 is provided between the second ring 1004 and the nut and is sleeved on the bolt 1002; scale lines distributed along its circumference are provided on the end face of the second ring 1004, and a second pointer mark 1001 pointing to the scale lines on the second ring 1004 is provided on the side wall of the splint 150.

[0062] Through the arrangement of the slide groove 1201, the second ring 1004, the sliding block 1301, the third spring 1003, the scale line and the second pointer mark 1001 in this embodiment, when the staff rotates the bolt 1002 to extend into the threaded through hole 840, the sliding block 1301 on the third spring 1003 slides along the slide groove 1201 and drives the second ring 1004 and the bolt 1002 to move and rotate; when the bolt 1002 moves downward, the third spring 1003 always holds the second ring 100 4 is pressed against the side wall of the clamping plate 150, so that the second pointer mark 1001 is conveniently pointed to the scale on the second ring 1004, which is convenient for workers to read; when the rectangular push plate 1101 needs to be reset, the worker only needs to rotate the bolt 1002 to drive the second ring 1004 to rotate, so that the second pointer mark 1001 on the clamping plate 150 points to the same scale on the second ring 1004, which is convenient for workers to reset the clamping plate 150.

[0063] In this embodiment, the end of the arc rod 530 close to the thin rod 520 is provided with a mounting groove 610 for the thin rod 520 to extend into, the end of the guide rod 1401 away from the second flange 920 is provided with a threaded column 1601, and the rectangular push plate 1101 is provided with a threaded blind hole 1501 for the threaded column 1601 to extend into.

[0064] Through the arrangement of the mounting groove 610, the threaded column 1601 and the threaded blind hole 1501 in this embodiment, an interference fit is achieved between the thin rod 520 and the mounting groove 610, thereby making it easier for the installer to install the thin rod 520 on the arc rod 530; the threaded column 1601 extends into the threaded blind hole 1501, thereby making it easier for the installer to install the guide rod 1401.

[0065] In this embodiment, the axes of the sleeves 930 at all the splints 150 are located on the same horizontal plane, and the intersection of the axes of all the sleeves 930 is the center point of the limit groove 810; the bottom surface of the pouring groove 250 is located on another horizontal plane, and the intersection of the other horizontal plane and the vertical line passing through the center point of the limit groove 810 is the center point of the pouring groove 250; the distance between the center point of the limit groove 810 and the center point of the pouring groove 250 is S, and the vertical distance between the center point of the limit groove 810 and the axis of the threaded rod 410 is L; the pitch of the thread pair between the threaded rod 410 and the nut 420 is W1, and the pitch of the thread pair between the threaded through hole 840 and the bolt 1002 is W2, W1:W2=S:L.

[0066] By setting the pitch ratio of the thread pair between the threaded rod 410 and the nut 420 in this embodiment, it is better to ensure that the nut 420 and the bolt 1002 maintain the same angle of rotation, thereby achieving both leveling and centering.

[0067] When the construction mold of this embodiment is actually used, it can be carried out according to the following steps:

[0068] S1. Laying out the lines means marking the location of the foundation pit to be dug. When laying out the lines, it is necessary to ensure that the area to be laid out is large enough to accommodate the mold, and the center of the area to be laid out is the center of the pole to be set up;

[0069] It is understandable that for the vertical poles cast directly on the ground, it is also necessary to mark at least the center of the vertical pole by laying out the lines;

[0070] S2. Excavation of foundation pit: excavation can be carried out along the layout area;

[0071] S3, placing the installation mold in the excavated foundation pit, and ensuring that the center point of the pouring groove 250 is located at the center of the layout area;

[0072] S4, installing the vertical pole, that is, fixing the vertical pole at the limiting groove 810;

[0073] S5, pouring, i.e. pouring concrete into the pouring tank 250;

[0074] S6. Remove the formwork. When the poured concrete is completely solidified or initially solidified, remove the construction formwork.

[0075] In the above process, the following effects can be achieved by using the construction mold of this embodiment:

[0076] 1. Due to the clamping of the limiting groove 810, the relative position of the vertical pole and the mold body 100 can remain unchanged, so the change of the vertical pole elevation caused by the downward movement of the vertical pole and the settlement of concrete can be avoided;

[0077] 2. Since the limiting groove 810 cooperates with the vertical pole from front to back and left to right, the verticality of the vertical pole can be better guaranteed and can be better adjusted through the corresponding mechanism;

[0078] 3. Since the center of the limiting groove 810 corresponds to the center of the pouring groove 250, the centering of the erected pole can be better ensured and can be better adjusted through the corresponding mechanism.

[0079] However, in reality, the bottom surface of the excavated foundation pit will be uncontrollably tilted, and this tilt will inevitably lead to a deviation angle and deviation distance between the vertical pole and the center line required for centering. At the same time, considering that the tilt is in space, that is, the deviation angle and deviation distance of the vertical pole will be distributed on a plane. In this embodiment: by forming an orthogonal adjustment mechanism between the four connecting lines in the front, back, left and right directions, the spatial adjustment of the deviation angle of the vertical pole can be better achieved; by forming an orthogonal rectangular push plate 1101 between the four connecting lines in the front, back, left and right directions, the spatial adjustment of the deviation distance of the vertical pole can be better achieved.

[0080] It is understandable that the above adjustment process can be performed after step S4 and before step S5. Specifically, among the above four adjustment mechanisms or four orthogonal rectangular push plates 1101, two opposite ones each form a group, and each group of adjustment mechanisms or rectangular push plates 1101 can provide adjustment of the deviation angle or deviation distance in an orthogonal direction.

[0081] However, there is actually a problem that, during the above adjustment process, the deviation angle can be adjusted to achieve leveling by placing a level ruler above the mounting mold; but when adjusting the deviation distance, it can only rely on naked eye observation, so it is difficult to ensure accuracy.

[0082] In order to further improve the accuracy of adjusting the deviation distance, in this embodiment, the axes of the sleeves 930 at all the clamps 150 are located at the same horizontal plane, and the intersection of the axes of all the sleeves 930 is the center point of the limit groove 810; the bottom surface of the injection groove 250 is located at another horizontal plane, and the intersection of the vertical line passing through the center point of the limit groove 810 at the other horizontal plane is the center point of the injection groove 250; the distance between the center point of the limit groove 810 and the center point of the injection groove 250 is S, and the vertical distance between the center point of the limit groove 810 and the axis of the threaded rod 410 is L; the pitch of the thread pair between the threaded rod 410 and the nut 420 is W1, and the pitch of the thread pair between the threaded through hole 840 and the bolt 1002 is W2, W1:W2=S:L. Among them, the dimensions S and L can be completed during production.

[0083] Through the above arrangement, during the adjustment process, the deviation angle and deviation distance can be adjusted in two orthogonal directions in steps; when adjusting the first orthogonal direction, a level ruler can be set in the orthogonal direction first, and then the nut 420 at the adjustment mechanism of the corresponding group can be adjusted to achieve leveling; in this process, the rotation angle of the nut 420 is recorded; and then the bolt 1002 is also adjusted according to the rotation angle, so that the deviation distance in the first orthogonal direction can be adjusted and the centering can be achieved preferably. When adjusting the second orthogonal direction, the above can be followed.

[0084] It is understandable that when the threaded rod 410 is adjusted outward by the nut 420, the corresponding rectangular push plate 1101 should be adjusted inward by the bolt 1002; and vice versa. Considering this, in this embodiment, the spiral direction of the threaded through hole 840 and the threaded pair of the bolt 1002 can be set to be consistent, so that the rotation direction of the nut 420 can be recorded and the bolt 1002 on the corresponding side can be adjusted in this rotation direction.

[0085] At the same time, this embodiment also analyzes the principle of this kind, as follows.

[0086] See Fig.18 , is a schematic diagram of the mathematical model of the construction mold of this embodiment in the first orthogonal direction under the tilted working condition. In this figure:

[0087] Plane AC is a horizontal plane flush with the ground, that is, theoretically the bottom surface of the excavated foundation pit should be a horizontal plane;

[0088] Plane AB is the actual ground surface of the foundation pit, that is, the bottom surface of the excavated foundation pit will have a certain slope;

[0089] Straight line L2 is the center line of the excavated foundation pit, that is, the line to which the erected poles should be centered;

[0090] The straight line L1 is the line connecting the center point of the limit groove 810 and the center point of the pouring groove 250, that is, the center axis of the vertical pole at the construction template;

[0091] Point P is the point where the sleeve 930 is located, and straight line L3 is a horizontal line passing through point P;

[0092] Point S is a point passing through the threaded rod 410, direction ST is the moving direction of the threaded rod 410, and line segment TQ is an extension line of line segment ST;

[0093] Among them, the distance OP is S, and the distance TP is L.

[0094] It can be known from the structure of the construction template of this embodiment that when there is a slope on the bottom surface of the excavated foundation pit, the vertical pole will deviate from the vertical direction by an angle and distance. Assuming that the angle of deviation in the first orthogonal direction is α, ∠BAC=∠ROP=∠QPT=α. Therefore, it can be known that the deviation distance can be adjusted by adjusting the rectangular push plate 1101 by the distance RP, and the deviation angle can be adjusted by adjusting the threaded rod 410 by the distance TQ. It can be known that the relationship between the distance RP and the distance TQ and the angle α is: RP=S·sinα; TQ=L·tanα. The relationship between the distance RP and the distance TQ and the pitch W1 and W2 is: RP= W1·β1; TQ= W2·β2. Therefore, the following relationship exists: W1·β1: W2·β2= S·sinα: L·tanα= S·cosα: L. Since the angle α is small, cosα can be regarded as 1, and at this time W1·β1:W2·β2= S:L exists. Among them, β1 and β2 are the theoretical rotation angles of the nut 420 and the bolt 1002, respectively. Therefore, in this embodiment, by controlling W1:W2=S:L, it can be better ensured that the nut 420 and the bolt 1002 maintain the same angle of rotation, so that leveling and centering can be achieved at the same time.

[0095] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
