Description

Technical Field

[0001] The invention relates to the technical field of building walls, and in particular to a combined screw-tightening type tension anchor bolt connector. Background Art

[0002] The insulation board body serves as the insulation layer of the building wall, which has the effect of heat preservation and sound insulation. The safety and fire protection standard field of the building places the insulation board body in the middle of the concrete layer to form a sandwich structure.

[0003] During the pouring process, the concrete poured at the bottom of the insulation board body is not poured at the same time. It is often the case that one side of the insulation board body is poured and then the other side. Moreover, the concrete is poured from the end with concrete into the end of the cavity. These will cause uneven force on the insulation board body, causing the insulation board body to shift, misalign or even break, thereby destroying the internal structure of the wall.

[0004] The multifunctional thermal insulation wall connector with application number 201320256407.1, the split sandwich thermal insulation wall connector with application number 201620392205.3, and the split sandwich thermal insulation wall combined connector with application number 201810328771.1, in the connectors disclosed in the above patents, the connector is inserted into the groove of the side wall of the thermal insulation board body, and then the thermal insulation board body with the connector inserted is laterally inserted. After the insertion is completed, the connector is fixed at both ends by steel bars, formwork, tension anchor bolts, etc., to fix the internal cavity. However, during assembly, the lateral insertion of the thermal insulation board body is the cooperation between the convex groove of the side wall of the thermal insulation board body and the corresponding groove. After the cooperation is completed, separation or gap may occur. The thermal insulation board body is not fixed in the up and down and left and right directions during insertion, and the convex groove and groove of the thermal insulation board body material are easy to break and damage, causing the thermal insulation structure to be damaged. Summary of the invention

[0005] The purpose of the present invention is to overcome the above problems and to propose a combined screw-on type tension anchor bolt connector.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The first connecting bridge is composed of three sections, the steel bars of the upper and lower sections are provided with threaded structures and are installed with tension nuts, the steel bars of the middle section are provided with threaded structures at both ends, the upper and lower sections are connected to the middle section through a connecting block, the connecting block is provided with a threaded structure inside, an injection molded shell A is provided on the steel bars of the middle section of the first connecting bridge, an injection molded plate A is provided at the upper end of the injection molded shell A, an injection molded plate B is provided at the lower end, a through hole A is provided on the injection molded plate A, the upper end connecting block is 160mm to 200mm away from the upper end of the injection molded shell A, and the lower end connecting block is 50 to 60mm away from the lower end of the injection molded shell A;

[0009] Support plates are provided at both ends of the steel bars of the second connecting bridge, and an injection molded shell B is provided on the steel bars. An injection molded plate C is provided at the upper end of the injection molded shell B, and an injection molded plate D is provided at the lower end. A through hole B is provided on the injection molded plate D. The upper support plate is 160 mm to 200 mm away from the upper end of the injection molded shell B, and the lower support plate is 50 to 60 mm away from the lower end of the injection molded shell B.

[0010] The injection molded shell A and the injection molded shell B are installed on the holes around the insulation board body, the second connecting bridge is inserted into the first connecting bridge, the through hole B passes through the lower end connecting block, the upper end support plate passes through the through hole A, the injection molded plate B is attached to the injection molded plate D, and the injection molded plate C is attached to the injection molded plate A;

[0011] The diameter of the steel bar is 8 mm, and the thicknesses of the injection molded plate A, the injection molded plate B, the injection molded plate and the injection molded plate D are 8 mm.

[0012] Furthermore, the connecting block can pass through the through hole B, while the injection molded plate B cannot pass through the through hole B.

[0013] Furthermore, the support plate can pass through the through hole A, but the injection molding plate C cannot pass through the through hole A.

[0014] Furthermore, the cross-section of the through hole A and the through hole B is a square with a side length of 40 mm or a circle with a radius of 20 mm.

[0015] Furthermore, the cross-section of the injection molded plate B and the injection molded plate C is a square with a side length of 60 mm or a circle with a radius of 30 mm.

[0016] Furthermore, the cross-section of the support plate and the connection block is a square with a side length of 40 mm or a circle with a radius of 30 mm.

[0017] Furthermore, the injection molded shell A is installed on the holes on the upper side and left side of the insulation board body, and the injection molded shell B is installed on the lower side and right side of the insulation board body, or the injection molded shell B is installed on the holes on the upper side and left side of the insulation board body, and the injection molded shell A is installed on the lower side and right side of the insulation board body.

[0018] Furthermore, the length of the injection molded shell A and the injection molded shell B is 1.5 mm smaller than the thickness of the insulation board body.

[0019] Furthermore, the thickness of the insulation board body is 80 mm to 100 mm.

[0020] Furthermore, the injection molding plate A and the injection molding plate C, and the injection molding plate D and the injection molding plate B are fixed by means of snap fasteners.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This connector is pushed in and installed on the side wall of the insulation board body. After the insulation board is matched, the connector effectively limits the front and rear movement of the insulation board body, thereby ensuring the spatial structure of the concrete protective layer cavity, the insulation board body layer and the concrete shear wall cavity.

[0023] 1. The first connecting bridge is a three-section structure, so that after the insulation board is assembled and poured and solidified, the tension anchor bolts at the upper and lower ends can be removed, so that the tension anchor bolts can be reused, saving resources, and the length of the steel bar is equal to the length of the second connecting bridge, which improves uniformity and facilitates the production of steel bars of this length.

[0024] 2. The support plate and the connecting block exert an outward force on the formwork along the steel bars. After tightening, the tension anchor bolts inserted into the iron pipe exert an inward force on the formwork along the steel bars, ensuring that the formwork will not move outward during concrete pouring and will not move inward when external force pushes on the formwork.

[0025] 3. The connecting blocks are installed at both ends of the steel bars, which plays the role of supporting the formwork. The threaded structure inside can connect the tension anchor bolts.

[0026] 4. The through hole A on the injection molding card A can allow the support plate to pass through, but not the injection molding plate C. The through hole B on the injection molding card B can allow the connection block to pass through, but not the injection molding plate C. This structure can prevent the connector from further displacement after the matching is completed, so that the steel bars of the first connecting bridge and the second connecting bridge are aligned, and the end faces of the connection block and the support plate are aligned. The whole after matching is from the upper end face of the steel bar to the injection molding plate D as a part, which corresponds to the concrete shear wall, the injection molding plate D to the injection molding plate A as a part, which corresponds to the insulation board body, and the injection molding plate A to the lower end face of the steel bar as a part, which corresponds to the concrete protective layer.

[0027] 5. The length of the injection-molded shell A and the injection-molded shell B is 1.5 mm smaller than the thickness of the insulation board body, so that the connector can be clamped on the hole of the insulation board body during installation.

[0028] 6. The upper connection block is 160mm~200mm away from the upper end of the injection molded shell A, the lower connection block is 50mm away from the lower end of the injection molded shell A, the upper support plate is 160mm~200mm away from the upper end of the injection molded shell B, and the lower support plate is 50mm away from the lower end of the injection molded shell B. The distance setting corresponds to the structural wall structure corresponding to the connecting piece. The setting of 160mm~200mm corresponds to the thickness of the concrete shear wall, and the thickness of 50~60mm corresponds to the concrete protective layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] After the connector 2 is pushed into place, Fig.12 The arrow direction below is the push-in direction of the insulation board body 1. After the mating is completed, the push-in direction is limited, but the opposite direction of the push-in direction can still be moved, and can be further fixed by snapping, such as Figure 4 The injection molding plate A212 and the injection molding plate C222, and the injection molding plate D223 and the injection molding plate B213 shown can be fixed by snapping together, for example Figure 4 shown.

[0061] Reference Figure 6-12 A dovetail groove 14 is provided on the surface of the insulation board body 1, and a dovetail mortise structure is provided around the insulation board body 1. The dovetail mortise structure has a convex dovetail 11 and a concave dovetail 12. The convex dovetail 11 and the concave dovetail 12 are alternately distributed around the insulation board body, and the convex dovetail 11 and the concave dovetail 12 are provided with holes 13.

[0062] The height of the insulation board body 1 is 2.5-3m, the width is 0.9-1.2m, the weight of the insulation board body 1 is equivalent to 3-4 times of the current weight. When pouring concrete, the weight of the insulation board body 1 is greater than the buoyancy generated by the concrete. A plurality of dovetail mortise structures are evenly spaced on the four side walls of the insulation board body 1. A convex dovetail 11 corresponding to the concave dovetail 12 is provided on the four side walls of the insulation board body 1. According to the setting of the height and length of the insulation board body 1, the length of the trapezoidal lower bottom 121 of the convex dovetail 11 is 30cm, the length of the trapezoidal upper bottom 122 is 15cm, and the length of the convex dovetail 11 corresponds to the shape and size of the concave dovetail 12. When the insulation board body 1 After the connection, the left and right forces will be offset, so that the insulation board body 1 is firmly connected without displacement, thereby ensuring the quality during use. The number of concave dovetails 12 and convex dovetails 11 needs to be set according to the height and width of the insulation board body 1. Dovetail grooves 14 are provided on both sides of the insulation board body 1. The dovetail grooves 14 provided on the surface of the insulation board body 1 will increase the bite of concrete and the insulation board, and the flat-push installation construction will be easier to operate. After the insulation board body 1 or the insulation board body 1 is installed, when there is still a little distance to the wall, according to the length of the insulation board body 1 from one side of the wall, one side is cut as shown in Figure 9, and then the dovetail mortise and tenon structure is connected without any gaps.

[0063] Move the convex dovetail 11 into the concave dovetail 12 on the insulation board body 1, and install them in sequence. When the insulation board body 1 is installed or the insulation board body is installed, when there is still a little distance to the wall, cut one side according to the insulation board body 1, such as Figure 5 As shown, the convex dovetail 11 and the concave dovetail 12 are made to correspond to each other. After the remaining steps are installed, concrete is poured. Since the weight of the insulation board body 1 is greater than that of an ordinary small insulation board body 1, the insulation board body 1 will not float upward during pouring. At the same time, due to the effects of the concave dovetail 12 and the convex dovetail 11, there will be no separation when subjected to forces from the left and right sides.

[0064] The right-angle insulation board is used for installation in the corner. When installing in the corner, it is not cut on one side and then connected with the dovetail structure. Instead, it is directly manufactured like Fig.13 The simplified top view of the right-angle insulation board shown in the figure does not show the dovetail groove 14 on the surface of the insulation board body 1, and the two sides of the right angle are 600mm.

[0065] A connecting piece 2 is installed on the hole 13 of the dovetail mortise structure, and the connecting piece 2 can prevent the front-to-back movement of the insulation board body 1 after installation.

[0066] like Fig.12As shown, the insulation board body 1 is assembled from right to left. First, the excess part of the insulation board body 1 is sawed off, and the sawed off part is the A part shown in the figure. The hole 13 at the dovetail mortise structure of the left wall of the A part cooperates with the injection molded shell B221 of the second connecting bridge 22, and the hole 13 of the dovetail mortise structure of the right wall of the insulation board body 1 of the B part cooperates with the injection molded shell A211 of the first connecting bridge 21. The insulation board body 1 of the B part is pushed in, and the dovetail mortise structure and the connecting bridge are cooperated with the insulation board body 1 of the A part. Similarly, The hole 13 at the dovetail mortise structure of the left side wall of part B is matched with the injection molded shell B221 of the second connecting bridge 22, and the hole 13 at the dovetail mortise structure of the right side wall of the insulation board body 1 of part C is matched with the injection molded shell A211 of the first connecting bridge 21, and the insulation board body 1 of part C is pushed in, and the dovetail mortise structure and the connecting bridge are matched with the insulation board body 1 of part B until the insulation board body 1 is assembled to the designated position, and the excess dovetail mortise structure is sawed off. If the designated position is a corner, put in a right-angle insulation board for assembly;

[0067] Similarly, the insulation board body 1 can also be assembled from left to right, then the second connecting bridge 22 is installed on the right wall of the insulation board body 1 on the far left, that is, the injection molded shell B221 is installed on the hole 13 of the dovetail mortise structure of the right wall, and the injection molded shell A211 is installed on the dovetail mortise structure on the left side of the inserted wall, the first connecting bridge 21 cooperates with the second connecting bridge 22, the concave dovetail 11 cooperates with the convex dovetail 12, and they are installed from left to right in sequence until the insulation board body 1 is assembled to the designated position, and the redundant dovetail mortise structure is sawed off. If the designated position is a corner, put in a right-angle insulation board for assembly;

[0068] For example, after the insulation board body 1 of part A is assembled with the insulation board body 1 of part B, a steel mesh 6 is reinforced in the cavity of the concrete shear wall 3 on one side of the insulation board body 1, templates 5 are placed at both ends of the connector 2, the threaded structure 241 on the tension anchor 242 passes through the through hole C51 on the template 5 and is screwed into the connection block, a square tube is placed between the tension anchor and the template, and the tension nut is tightened, as shown in FIG. Fig.14 As shown in the figure, in the tightened frame, the upper and lower ends of the connecting block and the supporting plate have an outward force along the steel bars on the inner surface of the template, and the tension anchor bolts at the upper and lower ends are pre-tightened and act on the iron pipe, which has an inward force along the steel bars on the surface of the template; Fig.11 The heat preservation board body 1 shown, after being plugged in, the dovetail mortise structure can limit the displacement up and down and left and right.

[0069] like Fig.15 As shown, concrete is poured into the cavity of the concrete protective layer 4 and the cavity of the concrete shear wall 3 until it solidifies.

[0070] like Fig.16As shown, loosen the tension nut, remove the steel pipe, unscrew the tension anchor bolt from the connection block, and remove the templates on both sides. The above removed parts can be reused;

[0071] like Fig.16 As shown, the holes at the connecting blocks are filled with foaming agent, and a plaster layer is applied at both ends of the concrete layer.

[0072] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
