Description

TECHNICAL FIELD

[0001] The utility model relates to building construction equipment technical field, concretely relates to a positioning device for embedded screw rod installation. BACKGROUND

[0002] The traditional embedded screw rod method is roughly divided into two categories, the first category is straight buried type, that is, before pouring concrete, the embedded screw rod is fixed and positioned by welding and reinforcing with the steel bars in the concrete structure, which puts forward relatively high requirements for the stability of the steel bars of the main structure, and is mostly suitable for the main steel bars that have been poured into the first-stage concrete and have high stability, the second category is two-stage embedding method, that is, pouring concrete in priority, and embedding a sleeve or a wooden box in the position where the embedded screw rod is needed before pouring concrete, and after the concrete reaches a certain strength, the sleeve or the wooden box is removed, the embedded screw rod is inserted into the hole, and then high-strength non-shrinkage grouting material or fine stone concrete is used for filling and fixing. Although this method can control the precision of the embedded part, it takes a long time and the cost of the material used for grouting is relatively high, which is not economical.

[0029] Figures 1 to 4This invention illustrates an embodiment of a positioning device for installing pre-embedded screws. The positioning device for installing pre-embedded screws in this embodiment includes a square template 1 and a positioning plate 2. The two sides of the positioning plate 2 are respectively supported on the top of the two sides of the square template 1, and the two sides of the positioning plate 2 are respectively fixed to the corresponding sides of the square template 1 by means of a fixing structure 3, which can be adjusted to move longitudinally and laterally. The positioning plate 2 is provided with positioning holes 5 for the pre-embedded screw 4 to pass through.

[0030] Usage process, such as Figure 3 and Figure 4 As shown: First, excavate the hole to be poured at the construction site; then, fix the square template 1 at the opening of the hole; next, adjust the horizontal and vertical positions of the positioning plate 2 so that the positioning hole 5 is aligned with the pre-embedded position of the pre-embedded screw 4; then, insert the pre-embedded screw 4 into the hole through the positioning hole 5, and fix the top of the pre-embedded screw 4 to the positioning plate 2 with a nut; next, pour concrete into the hole until the concrete is flush with the bottom surface of the positioning plate 2; after the concrete has solidified, remove the positioning device. On the one hand, moving the positioning plate 2 allows adjustment of the positioning position of the positioning hole 5, making it easy to adjust to the accurate position and improving construction efficiency; on the other hand, pouring concrete into the square template 1 up to the bottom surface of the positioning plate 2 reduces the amount of the top of the pre-embedded screw 4 protruding, increasing the pre-embedded length and strength of the pre-embedded screw 4.

[0031] Furthermore, in this embodiment, the fixing structure 3 includes a locking member 31, a longitudinal groove 32 on the square template 1, and a transverse groove 33 on the positioning plate 2. The locking member 31 passes through the corresponding longitudinal groove 32 and transverse groove 33, locking the square template 1 and the positioning plate 2. The longitudinal groove 32 is arranged longitudinally, and the transverse groove 33 is arranged transversely. After the locking member 31 is released, the positioning plate 2 can adjust its position relative to the square template 1 longitudinally and laterally, thereby adjusting the positioning position of the positioning hole 5. The structure is simple and the adjustment is convenient.

[0032] In this embodiment, the vertical direction is the width direction of the square template 1, and the horizontal direction is the length direction of the square template 1.

[0033] Furthermore, in this embodiment, the locking element 31 is a locking bolt.

[0034] Furthermore, in this embodiment, the transverse groove 33 extends to the corresponding side of the positioning plate 2. The transverse grooves 33 on both sides of the positioning plate 2 respectively extend to the side surface of their respective positioning plate 2 sides, for example, as... Figure 2 As shown, the horizontal groove 33 on the left side of the positioning plate 2 extends to the left side of the positioning plate 2, and the horizontal groove 33 on the right side of the positioning plate 2 extends to the right side of the positioning plate 2. In this way, the positioning plate 2 can be removed by simply removing one side of the locking piece 31. At the same time, one or both sides of the locking piece 31 can be installed first, and then the positioning plate 2 can be installed. This improves the convenience of installing and removing the positioning plate 2.

[0035] Further, in the embodiment, as shown in Figure 1 and Figure 2 , the longitudinal groove 32 is a waist-shaped groove.

[0036] Further, in the embodiment, the positioning plate 2 is provided with pouring openings 6 on both sides. It is convenient to pour concrete into the to-be-poured hole.

The pouring opening 6 penetrates to the corresponding side of the positioning plate 2, as shown in Figure 1 and Figure 2 , the pouring opening 6 on the left side of the positioning plate 2 penetrates to the left side of the positioning plate 2, and the pouring opening 6 on the right side of the positioning plate 2 penetrates to the right side of the positioning plate 2, which is convenient for pouring and reduces the weight of the positioning plate 2. The positioning plate 2 on both sides of the pouring opening 6 is fixed on the square formwork 1 through the fixing structure 3, specifically, the side walls on both sides of the opening of the pouring opening 6 are fixed on the corresponding side of the square formwork 1 through the fixing structure 3. That is to say, the side walls on both sides of the opening of the pouring opening 6 are provided with transverse grooves 33, the square formwork 1 is provided with longitudinal grooves 32 at the corresponding positions of the transverse grooves 33, and locking pieces 31 are arranged in the transverse grooves 33 and the longitudinal grooves 32 which are connected in a top-to-bottom manner. It can be understood that the positioning plate 2 is fixed at the four corners through the fixing structure 3, and the stability is good.

[0038] Further, in the embodiment, the positioning plate 2 is provided with a through opening 7 at the middle part, and the positioning holes 5 are arranged in multiple numbers and are arranged at intervals around the center of the through opening 7.

[0039] Further, in the embodiment, as shown in Figure 1 and Figure 4 , each adjacent side of the square formwork 1 is fixedly connected through a fixing screw 8. It is convenient for the manufacturing of the square formwork 1.

[0040] Further, in the embodiment, as shown in Figure 3 and Figure 4 , each side of the square formwork 1 is in a U shape with the opening outward, and the square formwork 1 is provided with a heightening die 9 on the top surface, and the positioning plate 2 is supported on the top surface of the heightening die 9.
