Description

Technical Field

[0001] The utility model relates to the technical field of shaft template construction, in particular to an embedded box fixing structure suitable for claw arm positioning installation. Background Art

[0002] During the construction of the elevator shaft, the shaft wall needs to be poured from bottom to top in the shaft. When pouring the upper layer, a positioning box needs to be reserved on the shaft template. In this way, after the pouring of the shaft wall is completed, installation holes can be left on the completed shaft wall. In this way, when in use, the claw arm on the climbing machine hoisted into the elevator shaft can be stuck in the positioning box reserved in the shaft wall for pouring construction. When the pouring of this layer is completed, the formwork is removed, and then the self-climbing system at the construction site is used to lift the formwork system. During the self-climbing process, the claw arm is stuck in the pre-buried positioning box to achieve support and positioning of the claw arm, thereby facilitating the start of pouring construction on the upper layer.

[0003] In the prior art, when the positioning box is embedded, the positioning box needs to be fixed on the template. During the fixing process, the box is usually not firmly fixed and becomes loose, which affects the installation accuracy of the positioning box. Utility Model Content

[0004] The utility model provides a pre-embedded box fixing structure suitable for the positioning installation of a claw arm, aiming to improve the installation fastness of the positioning box, thereby improving the installation accuracy of the positioning box.

[0005] The utility model is achieved through the following technical scheme: an embedded box fixing structure suitable for claw arm positioning installation, including an inner template of a rectangular structure, both ends of the inner template are connected to positioning boxes, the inner side of the positioning box is threadedly connected to a screw rod, the end of the screw rod away from the positioning box passes through the inner template, and the side of the screw rod away from the positioning box is threadedly connected to a nut, a fixing block is sleeved on the screw rod, the fixing block is located between the nut and the inner template, and tightening the nut can make the fixing block press against the inner template and fix the positioning box on the inner template.

[0006] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0007] After the screw rod in the utility model connects the positioning box, the screw rod is inserted into the inner template and finally tightened and fixed by the nut, so that the positioning box is fixed on the inner template, which is convenient for forming a hole for supporting the claw arm after pouring concrete in the later stage. The operation is convenient and simple. In the utility model, a fixing block is also added, and the fixing block is sleeved on the screw rod, so that the fixing block plays the role of a cushion block. When the nut is tightened, pressure can be applied to the fixing block to make the fastening between the nut and the inner template stronger, thereby further enhancing the installation fastening and firmness of the positioning box, thereby improving the installation accuracy of the positioning box.

[0008] Furthermore, one end of the fixing block in contact with the inner template is an inclined surface.

[0009] Beneficial effect: In this solution, the end face of the fixed block is designed to be an inclined end, in order to form an inlay between the inner wall steel mold of the well climbing machine and the position of the transition joint, so that the screw rod always remains vertical to the inner template during the tightening process. After being firmly reinforced, it is not easy for the screw rod to loosen due to external force, so that the fixing plate of the positioning box fits more closely on the inner template. It ensures that the positioning box will not deviate during the pouring of concrete, and can better ensure accurate positioning.

[0010] Furthermore, the inner side of the positioning box is connected to a limiting cylinder, and the screw rod is threadedly connected to the limiting cylinder.

[0011] Beneficial effect: Such arrangement facilitates quick connection and cooperation between the screw rod and the positioning box, and facilitates the separation of the positioning box and the inner template by twisting the screw rod out of the limiting cylinder during later demoulding.

[0012] Furthermore, the limiting cylinder is located at the upper part of the positioning box.

[0013] Beneficial effect: Such a setting can avoid obstacles to the claw arm when inserting the claw arm later, so that the claw arm can be inserted into the reserved positioning box more smoothly and flatly later, thereby improving the installation accuracy of the claw arm.

[0014] Furthermore, it also includes a fixing plate, which is connected to the inner template, the positioning box cover is on the fixing plate, and one end of the screw rod can pass through the fixing plate.

[0015] Beneficial effect: The setting of the fixed plate in this solution can facilitate the demoulding of the positioning box at a later stage, making demoulding easier, and can further protect the interior of the positioning box, reducing or avoiding the poured concrete from entering the positioning box.

[0016] Furthermore, positioning plates are symmetrically connected to both sides of the fixing plate, and both sides of the positioning box are extended outward to form positioning edges, and the positioning edges on both sides of the positioning box can be inserted between the positioning plates on both sides of the fixing plate.

[0017] Beneficial effect: The setting of the positioning plate in this solution can limit the lateral displacement of the positioning box, improve the installation accuracy of the positioning box, and avoid the rotational offset of the positioning box, so that the position of the hole formed later meets the requirements of the claw arm installation, making the claw arm installation position more accurate.

[0018] Furthermore, a limiting member for supporting the positioning box is provided at the bottom of the positioning plate, and the limiting member is threadably matched with the inner template.

[0019] Beneficial effect: The limit piece can limit the positioning box, so when installing the positioning box, since the limit piece can support the positioning box, it is more convenient to operate when installing and fixing the positioning box, and since the limit piece cooperates with the inner template thread, after the positioning box is installed, the length of the limit piece extending out of the inner template can be reduced by rotating the limit piece, thereby avoiding affecting the embedded space position of the positioning box.

[0020] Furthermore, the limiting member includes a supporting portion and a threaded portion, one end of the threaded portion is connected to one end of the supporting portion, the other end of the threaded portion is connected to a handle, a thread is provided on the outer side of the threaded portion, and the supporting portion is in the shape of a rectangular parallelepiped.

[0021] Beneficial effect: In this solution, the threaded portion is used to cooperate with the column thread, which is convenient for adjusting the extended length of the support portion, and the support portion is in the shape of a rectangular parallelepiped, so that the supporting surface of the positioning box is flatter and the supporting effect is better.

[0022] Furthermore, a boss is provided at one end of the fixing plate away from the inner template, and the positioning box can be covered on the boss.

[0023] Beneficial effect: This solution adopts another method of limiting the support of the positioning box. In this solution, a boss is set on the fixed plate so that the boss and the inner side of the positioning box can cooperate with each other to achieve the limitation and positioning of the positioning box. This structure can quickly position the positioning box, and it is more convenient to operate when fixing the positioning box in the later stage.

[0024] Furthermore, the boss is clearance-matched with the inner side of the positioning box, and the contour shape of the boss matches the inner contour shape of the positioning box.

[0025] Beneficial effect: The clearance between the boss and the positioning box of this solution can ensure that the positioning box is smoothly covered on the boss. At the same time, the contour shape of the boss matches the internal contour shape of the positioning box, which can limit the positioning box on all sides and effectively improve the limiting effect of the positioning box.

Figure 2 As shown, the side formwork 3 and four columns 2 enclose an inner formwork of a rectangular structure, and the structure enclosed by the side formwork 3 and the columns 2 is a formwork structure used when pouring the shaft wall.

[0038] The number of the positioning boxes 1 in this embodiment needs to be consistent with the actual number of claw arms. In this embodiment, four positioning boxes 1 are provided, and the four positioning boxes 1 are respectively located on four columns 2 .

[0039] A screw rod 7 is threadedly connected to the inner side of the positioning box 1. The end of the screw rod 7 away from the positioning box 1 passes through the column 2 of the inner template. The side of the screw rod 7 away from the positioning box 1 is threadedly connected to a nut 9. A fixing block 8 is sleeved on the screw rod 7, and the fixing block 8 is located between the nut 9 and the column 2 of the inner template. Tightening the nut 9 can make the fixing block 8 press against the column 2 of the inner template and achieve the purpose of fixing the positioning box 1 on the inner template. Specifically: in this embodiment, the end of the fixing block 8 in contact with the column 2 is an inclined surface, which can form an inlay effect between the fixing block 8 and the inner wall steel mold of the climbing machine hoisted into the well and the position at the transition seam, so that the screw rod always remains in a state of vertical inner template during the tightening process. After reinforcement, it is not easy to cause the screw rod to loosen due to external force, so that the fixing plate can fit more closely on the column of the inner template, ensuring that the positioning box will not deviate during the concrete pouring process, and further ensuring the accurate positioning of the positioning box.

[0040] The inner side of the positioning box 1 is connected to a limiting cylinder 6, which is located at the upper part of the positioning box 1 to avoid obstruction to the installation of the claw arm in the later stage. In this embodiment, the positioning box 1 and the limiting cylinder 6 are both made of plastic material, and the positioning box 1 and the limiting cylinder 6 are integrally formed, and the screw rod 7 is threadedly connected to the limiting cylinder 6, thereby realizing the connection between the screw rod 7 and the positioning box 1.

[0041] In this embodiment, a pre-embedded box fixing structure suitable for claw arm positioning installation also includes a fixing plate 4, which is connected to the column 2. The positioning box 1 is covered on the fixing plate 4, and one end of the screw rod 7 can pass through the fixing plate 4. In this embodiment, a through hole for the screw rod 7 to pass through is opened on the fixing plate 4 and the column 2.

[0042] The specific implementation process is as follows:

[0043] When installing the positioning box 1, first fix the fixing plate 4 on the column 2 by fixing screws 5, and then place the positioning box 1 on the fixing plate 4, and then pass the screw rod 7 through the column 2 and the fixing plate 4 and threadedly cooperate with the limiting tube 6 on the positioning box 1 to achieve preliminary connection, and then coaxially sleeve the fixing block 8 on the screw rod 7, and make the end of the fixing block 8 with the inclined surface face the side of the column 2, and finally tighten the nut 9 on the screw rod 7. In the process of tightening the nut 9, the fixing block 8 will be gradually squeezed until the positioning box 1 is completely fixed on the column 2.

[0044] Example 2

[0045] like Figure 3 and Figure 4 As shown, a pre-embedded box fixing structure suitable for claw arm positioning installation, the difference between this embodiment and embodiment 1 is that: positioning plates 202 are symmetrically connected to the two sides of the fixing plate 4, the positioning plates 202 and the fixing plate 4 are connected by screws or integrally formed or other methods, and the two sides of the positioning box 1 are extended outward to form positioning edges 101, and the positioning edges 101 on both sides of the positioning box 1 can be inserted between the positioning plates 202 on both sides of the fixing plate 4, and the positioning plates 202 on both sides can limit the horizontal displacement of the positioning box 1, so as to avoid the positioning box 1 from being skewed and rotated after being fixed on the column 2, thereby affecting the accurate installation of the positioning box 1.

[0046] Example 3

[0047] like Figure 5 As shown, a pre-embedded box fixing structure suitable for claw arm positioning installation, the difference between this embodiment and embodiment 2 is that: a limiting member for supporting the positioning box 1 is provided at the bottom of the positioning plate 202, and the limiting member is threadedly matched with the column 2.
