Description

Technical Field

[0001] The invention relates to the field of photovoltaic construction, and in particular to a construction structure for installing photovoltaic components. Background Art

[0002] Before installing photovoltaic modules, foundation piles need to be set up first. The existing foundation pile construction requires first digging an installation pit on the ground, then placing cast-in-place piles in the pit, and then pouring concrete to form foundation piles. The cast-in-place piles are composed of a pile barrel and a steel cage. The pile barrel is used to connect the installation bracket of the photovoltaic module. When manually placing the cast-in-place piles in the installation pit, the cast-in-place piles need to be changed from horizontal to vertical and placed in the installation pit. The cast-in-place piles have a certain length as a whole. When workers change the horizontal cast-in-place piles to a vertical state and place them in the installation pit, two people are required to cooperate to lift and align the long cast-in-place piles. Before installing photovoltaic modules, a large number of cast-in-place piles need to be arranged. In this way, workers need to repeatedly operate to place the cast-in-place piles in the installation pit. The workers have high labor intensity and low arrangement efficiency.

[0003] In addition, when workers transform the horizontal cast-in-place piles into a vertical state and place them into the installation pit, the cast-in-place piles contact the edge of the entrance of the installation pit, which can easily cause the entrance of the installation pit to collapse and a large amount of soil to fall into the installation pit. Especially when the soil around the installation pit is soft, the collapse is more serious and more soil falls into the installation pit. The soil falling into the installation pit will cause the bottom of the installation pit to be uneven. After the bottom of the steel cage contacts the uneven bottom of the installation pit, the cast-in-place piles in the installation pit are in a tilted state, affecting the formation of the foundation piles. Summary of the invention

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings. Example 1

[0030] like Figure 1-Figure 8 As shown, a construction structure for installing photovoltaic modules includes a pile tube 1 and a steel cage 2; the lower side of the pile tube 1 is connected to the steel cage 2;

[0031] It also includes a protective cover 3, a connecting block 4, a locking rod 5 and a swivel 6; two gripping rods 11 are threadedly connected to the upper side of the pile barrel 1; the steel cage 2 is composed of a connecting barrel 21, a plurality of steel bars 22 welded to the outer circumference of the connecting barrel 21, and a steel ring 23 welded from top to bottom on the outside of all the steel bars 22; the pile barrel 1 is sleeved with the connecting barrel 21, and the outer diameter of the pile barrel 1 except the bottom is the same as the inner diameter of the connecting barrel 21; the bottom of the pile barrel 1 is in the shape of a truncated cone, and the maximum outer diameter of the truncated cone is larger than the inner diameter of the connecting barrel 21; a protective cover 3 is movably connected to the bottom of the steel cage 2; the protective cover 3 is composed of a hollow disc and a hollow circular sleeve, and the hollow disc is a protective cover. The horizontal side of the shield 3 and the hollow circular sleeve are the vertical sides of the shield 3; four avoidance grooves 31 are provided on the shield 3; four connecting blocks 4 are fixedly connected to the shield 3; four locking rods 5 are connected to the shield 3 through torsion springs, and the connection between the locking rods 5 and the shield 3 is located directly above the corresponding avoidance grooves 31; a swivel 6 is slidably connected to all the connecting blocks 4; all the rotating columns 51 are in contact with the bottom surface of the swivel 6; four unlocking grooves 61 are provided on the swivel 6, and the unlocking grooves 61 are staggered with the locking rods 5; four slide grooves 62 are provided on the bottom surface of the swivel 6; each connecting block 4 is located in a slide groove 62; a handle 63 is welded on the swivel 6.

[0032] It also includes an insertion rod 7; three connecting frames 32 are installed in a circular shape on the horizontal side of the protective cover 3; each connecting frame 32 is slidably connected to a insertion rod 7; the bottom of the insertion rod 7 is conical, and the insertion rod 7 passes through the protective cover 3.

[0033] A rotating column 51 is rotatably connected to one side of each locking rod 5 away from the center of the protective cover 3 , and is used to reduce the friction force of contact with the bottom surface of the rotating ring 6 , so as to facilitate the rotation of the rotating ring 6 .

[0034] A limiting ball 52 is welded on one side of each locking rod 5 facing the center of the protective cover 3 to prevent the steel bar ring 23 from being horizontally offset when the locking rod 5 restricts the steel bar ring 23 .

[0035] A cylindrical block larger than the diameter of the rod 7 is provided on the top of the rod 7 to prevent the rod 7 from falling off the protective cover 3. At the same time, the user can hammer the cylindrical block with a tool to hammer the rod 7 into the ground 1111 to fix it.

[0036] The surface of the grip 11 is provided with a rubber layer to improve the grip comfort and anti-slip performance.

[0037] The surface of the handle 63 is provided with an anti-skid structure to prevent the user from slipping when touching it.

[0038] The bored pile of the present invention is composed of a pile barrel 1, a steel cage 2 and a connecting barrel 21. The pile barrel 1 is movable through the connecting barrel 21, so that the pile barrel 1 can be initially retracted in the steel cage 2. Different from the existing ones, the length of the bored pile is shortened, so that the user can flip the bored pile from a horizontal state to a vertical state, saving physical strength. After the length of the bored pile is shortened, it is also convenient for a single user to operate the bored pile. It should be noted that the upper part of the pile barrel 1 is threadedly connected to the gripping rod 11, and the pile barrel 1 is restricted by the gripping rod 11 to prevent the pile barrel 1 from being separated from the connecting barrel 21.

[0039] When placing the bored pile, the pile barrel 1 is initially retracted in the steel cage 2 for placement. The user moves the bored pile to the installation pit 2222 and places the bottom of the steel cage 2 above the installation pit 2222. The user then stands the bored pile upright, and the bottom of the steel cage 2 enters the installation pit 2222, and simultaneously releases the bored pile, so that the bored pile freely falls into the installation pit 2222 until the bottom of the steel cage 2 contacts the bottom of the installation pit 2222. The bored pile is then placed in place. The user then reaches into the installation pit 2222, holds the grip 11, and lifts the pile barrel 1 upward. The pile barrel 1 moves upward relative to the steel cage 2, so that its upper part extends out of the installation pit 2222. The bottom of the pile barrel 1 is truncated cone-shaped, with the maximum truncated cone size. The outer diameter is larger than the inner diameter of the connecting tube 21. During the rising process of the pile tube 1, the bottom conical part is stuck in the bottom of the connecting tube 21, and then the pile tube 1 and the connecting tube 21 are stuck. As a result, the relative positions of the pile tube 1 and the connecting tube 21 are locked, and the pile tube 1 is completely extended from the steel cage 2. The bored pile is in a standard state, and the placement of the bored pile is completed. After that, the user can remove the gripping rod 11 threadedly connected to the pile tube 1 for the placement of the next batch of bored piles, saving costs; and then pour concrete into the installation pit 2222 through the pile tube 1 to fill the pile tube 1, the internal space of the steel cage 2 and the installation pit 2222. After the concrete is cured, the pile tube 1 and the steel cage 2 are fixed, and the bored pile is formed. The photovoltaic bracket can be connected to the bored pile through the pile tube 1.

[0040] When the cast-in-place pile changes from a horizontal state to a vertical state at the entrance of the installation pit 2222, the steel cage 2 contacts the edge of the entrance of the installation pit 2222, which may easily cause the entrance of the installation pit 2222 to collapse, and a large amount of soil falls into the installation pit 2222, resulting in an uneven bottom of the installation pit 2222. After the bottom of the steel cage 2 contacts the uneven bottom of the installation pit 2222, the pile barrel 1 and the steel cage 2 located in the installation pit 2222 are tilted as a whole, affecting the pouring and subsequent installation of the photovoltaic bracket; therefore, before placing the pile barrel 1 and the steel cage 2 into the installation pit 2222, the user first places the protective cover 3 at the entrance of the installation pit 2222. The protective cover The horizontal side of 3 covers the ground 1111 around the entrance of the installation pit 2222, and the vertical side will extend into the installation pit 2222, thereby fixing the soil at the entrance of the installation pit 2222 through the protective cover 3. When the pile tube 1 and the steel cage 2 are placed in the installation pit 2222, the steel cage 2 contacts the protective cover 3, and the protective cover 3 evenly distributes the pressure to the ground 1111 around the entrance of the installation pit 2222 to avoid the entrance from collapsing and the soil from falling into the installation pit 2222, resulting in an uneven bottom of the installation pit 2222. After the cast-in-place pile is installed, the protective cover 3 can be removed from the entrance of the installation pit 2222 for use in the next cast-in-place pile installation, saving costs.

[0041] When installing cast-in-place piles, users usually wear gloves to avoid hurting their hands. When users support the steel cage 2 to erect it, the gloves are easily stuck in the gap between the steel bar 22 and the steel ring 23. When the user lets go of the steel cage 2 and allows it to fall freely into the installation pit 2222, the gloves are stuck on the steel cage 2. The free-falling steel cage 2 will pull the user to fall towards it, posing a safety hazard. For this reason, a locking rod 5 is provided on the protective cover 3. After the user places the protective cover 3 at the entrance of the installation pit 2222, as shown in FIG. Fig. 9 As shown, the locking rod 5 is in a horizontal state, and the rotating column 51 thereon contacts the bottom surface of the rotating ring 6, restricting the locking rod 5 from turning downward. Then, the user moves the cast-in-place pile to the protective cover 3, so that it changes from a horizontal state to a vertical state, as shown in FIG. Figure 8 As shown, the bottom of the steel ring 23 at the lowermost side of the steel cage 2 will contact all the locking rods 5, and the locking rods 5 will support and limit the pile barrel 1 and the steel cage 2, so that the pile barrel 1 and the steel cage 2 cannot fall downward into the installation pit 2222, thereby making the pile barrel 1 and the steel cage 2 in a vertical state stand above the installation pit 2222. Then the user releases the pile barrel 1 and the steel cage 2, and touches the handle 63 with his hand or foot to drive the swivel 6 to rotate relative to the protective cover 3. During the rotation of the swivel 6, the connecting block 4 slides relative to the slide groove 62 until the swivel 6 is in the state of being rotated. After the ring 6 rotates to align the unlocking groove 61 with the locking rod 5, the rotating column 51 will lose the restriction of the rotating ring 6, and then the locking rod 5 will flip downward under the pressure of the weight of the pile barrel 1 and the steel cage 2. At the same time, the pile barrel 1 and the steel cage 2 freely fall into the installation pit 2222. Therefore, when the pile barrel 1 and the steel cage 2 freely fall, the user's gloved hands will not contact the steel cage 2, avoiding the gloves from being stuck in the gap at the connection between the steel bar 22 and the steel ring 23, and pulling the user when the pile barrel 1 and the steel cage 2 freely fall, causing safety problems.

[0042] When the pile barrel 1 and the steel cage 2 fall freely into the installation pit 2222, the gripping rod 11 will contact the upper surface of the protective cover 3, thereby limiting the top of the pile barrel 1 from falling into the installation pit 2222. At the same time, the steel cage 2 continues to move downward relative to the pile barrel 1 until the steel cage 2 contacts the bottom surface of the installation pit 2222. Then, the user can hold the gripping rod 11 to lift the pile barrel 1, so that the pile barrel 1 extends out of the installation pit 2222, and rotate the pile barrel 1 to lock it with the steel cage 2, thus completing the arrangement work. In this way, the pile barrel 1 is restricted at the entrance of the installation pit 2222 by the gripping rod 11. Compared with the aforementioned steps, the user does not need to bend down and reach into the installation pit 2222 to grab the gripping rod 11 to lift the pile tube 1, which is convenient for operation; then the user removes the protective cover 3 and the parts thereon from the entrance of the installation pit 2222 and reuses them; when the protective cover 3 passes upward through the placed cast-in-place piles, the locking rod 5 contacts the outer surface of the connecting tube 21 and keeps flipping downward. After the protective cover 3 is removed, the locking rod 5 will return to a horizontal state under the action of the torsion spring, and then the user turns the swivel 6 again to limit the locking rod 5.

[0043] Furthermore, when the pile cylinder 1 and the steel reinforcement cage 2 are changed from a horizontal state to a vertical state on the protective cover 3, when the posture of the steel reinforcement cage 2 changes, it will squeeze the protective cover 3, causing the protective cover 3 to deviate from the center of the installation pit 2222. After the pile cylinder 1 and the steel reinforcement cage 2 stand vertically above the protective cover 3, the pile cylinder 1 and the steel reinforcement cage 2 are offset and misaligned with the center of the installation pit 2222, resulting in the pile cylinder 1 and the steel reinforcement cage 2 rubbing against the side wall of the installation pit 2222 or even the bottom of the steel reinforcement cage 2 being inserted into the side wall of the installation pit 2222 when they free fall, and the pile cylinder 1 and the steel reinforcement cage 2 cannot smoothly fall into the installation pit 2222, which requires workers to spend extra time and effort to adjust; furthermore, by setting the insertion rods 7 on the horizontal side of the protective cover 3, after the protective cover 3 is placed at the entrance of the installation pit 2222, the user inserts the insertion rods 7 downward into the soil around the installation pit 2222 to fix the current position of the protective cover 3. When the posture of the steel reinforcement cage 2 changes, it prevents the protective cover 3 from deviating, avoiding the pile cylinder 1 and the steel reinforcement cage 2 standing vertically on the protective cover 3 from being offset and misaligned with the center of the installation pit 2222, and the pile cylinder 1 and the steel reinforcement cage 2 cannot smoothly fall into the installation pit 2222. Embodiment 2

[0044] On the basis of Embodiment 1, as Figure 1 、 Fig. 9 and Fig.10 shown, it further includes an anti-tipping component, and the anti-tipping component includes a sliding block 101 and a limiting ring 102; a sliding block 101 is slidably connected to each insertion rod 7; all the sliding blocks 101 are fixedly connected to form a limiting ring 102 together; the inner diameter of the limiting ring 102 is larger than the outer diameter of the steel reinforcement cage 2; a plurality of insertion holes 701 are vertically arranged on each insertion rod 7; a plug pin 702 is inserted into each insertion rod 7, and the plug pin 702 is the same size as the insertion hole 701; the plug pin 702 is used to lock the sliding block 101.

[0045] The insertion end of the plug pin 702 is conical; it is convenient to insert into the insertion hole 701.

[0046] A pull ring is welded on the plug pin 702; it is convenient for the user to pull the plug pin 702.

[0047] When the pile cylinder 1 is inside the steel reinforcement cage 2 and the overall length is shortened, the total length of the pile cylinder 1 and the steel reinforcement cage 2 is still about two-thirds of the user's height. At this time, the protective cover 3 and related parts only support the steel reinforcement cage 2 at the bottom. After the user releases the hand, the pile cylinder 1 and the steel reinforcement cage 2 standing on the protective cover 3 have no support. When the steel reinforcement cage 2 is released through the locking rod 5 and the rotating ring 6, the pile cylinder 1 and the steel reinforcement cage 2 are prone to tipping when falling into the installation pit 2222.

[0048] Therefore, the limiting ring 102 is provided. In the initial state, as Figure 1As shown, the limiting ring 102 is close to the top of the protective cover 3. The user places the pile barrel 1 and the steel cage 2 on the protective cover 3. When supported by the locking rod 5, the lower side of the steel cage 2 is located in the limiting ring 102. Then the user pulls out the latch 702, pulls the limiting ring 102 to drive the sliding block 101 to slide upward on the insertion rod 7, away from the protective cover 3. According to the height of the pile barrel 1 and the steel cage 2, the insertion hole 701 corresponding to a position more than one-third of their height is selected, so that the lower side of the sliding block 101 is located above the insertion hole 701. Then, the pin 702 is inserted into the socket 701 to fix the height of the sliding block 101 and the limit ring 102, so that the parts on the protective cover 3 and the limit ring 102 cooperate to form a limiting support for the lower half of the pile barrel 1 and the steel cage 2, thereby increasing the limit on the height of the pile barrel 1 and the steel cage 2. When the locking rod 5 is unlocked and the pile barrel 1 and the steel cage 2 fall into the installation pit 2222, the limit ring 102 limits the pile barrel 1 and the steel cage 2 to prevent the pile barrel 1 and the steel cage 2 from tipping over when they are placed in the installation pit 2222.
