Description

Technical Field

[0001] The invention relates to the technical field of floor construction, and in particular to a hollow floor BBF pipe positioning anti-floating device and a rapid construction tooling thereof. Background Art

[0002] In the construction of floor slabs, a technical solution for hollow floor slabs is gradually becoming popular. That is, before pouring the floor slab, a steel skeleton is laid in the formwork, and high-strength prefabricated parts are placed between the steel skeletons, generally lightweight and high-strength hollow parts, such as BBF pipes, BDF thin-walled pipes, GRF pipes, etc. By filling the prefabricated parts, the amount of concrete used can be reduced, and the weight of the floor slab can be reduced. At the same time, the amount of concrete used is reduced, and the overall pouring, curing and maintenance time is shortened, which can improve the efficiency of construction.

[0003] When the existing BBF pipe is fixed, steel bars are usually placed above and below it for clamping, and the two steel bars are connected by a Figure 7 First of all, the density of BBF pipe laying is high, so the connector is not easy to install. At the same time, the connector is tightly clamped by the steel bar, but it cannot completely limit the position of both sides of the BBF pipe. When the concrete is poured and compacted, if the BBF pipe is misplaced, it will affect the quality of the floor. Summary of the invention

[0004] To solve the above problems, the present invention discloses a hollow floor BBF pipe positioning and anti-floating device, which is a fastener, and the fastener is a rod bent into a V-shaped member. During construction, the fastener is fixed with an installation tool to position and fix the BBF pipe.

[0005] The fast construction tool is an installation tool, which includes a lower support and a pressure rod. The lower end of the lower support is slidably provided with an insertion rod, and the upper end of the insertion rod is provided with a bracket. The upper side wall of the front of the lower support is fixedly connected with a clamp, and the clamp is located above the bracket. When in use, the lower part of the clamp is placed in the bracket, and then the clamp is buckled in the upper steel bar at the upper end of the BBF pipe. At the same time, the two ends of the clamp are also bent so that it can be buckled on the upper steel bar.

[0006] The lower back of the lower support is fixedly connected with a support block, the end of the support block is rotatably connected to the lower part of the pressure rod, and the lower end of the pressure rod is rotatably connected to the end of the insertion rod. By rotating the pressure rod, the insertion rod is pushed from the back to the front, and then the lower end of the fastener is bent to hook the lower steel bar.

[0007] The lower end of the pressure rod is provided with a long hole, and the end of the insertion rod is penetrated with a first shaft pin, and the first shaft pin and the long hole are slidably matched. The long hole is provided to eliminate the displacement between the pressure rod and the insertion rod when the pressure rod rotates.

[0008] Preferably, a second axle pin is inserted through the rotation connection between the support block and the pressure rod to achieve the rotation connection between the support block and the pressure rod.

[0009] Preferably, the upper end of the lower support is fixedly connected with a handle, and the upper side wall of the handle is fixedly connected with a fixing rod, and the fixing rod fits in a through hole preset on the upper part of the pressure rod. The pressure rod is fixed by the fixing rod, and the fixing rod is fixed horizontally. Since the pressure rod is connected by rotation, its moving track is fan-shaped. When the fixing rod is inserted into the through hole, the side wall of the fixing rod and the through hole fit tightly, and the friction force generated can limit the natural movement of the pressure rod. When using the pressure rod, it only needs to be pushed backward with great force.

[0010] Preferably, a placement piece is fixedly connected to the front side wall of the lower supporting piece, and a slot is provided on the front of the placement piece. The placement piece is used to support the upper part of the buckle.

[0011] Preferably, a fixing ring is provided in the middle of the front side of the lower support, and a buckling piece is movably provided on the fixing ring. When the opening angle of the buckle needs to be precisely controlled, a cross bar is required to be added to the buckle, and both ends of the cross bar are provided with openings, and the openings clamp the upper part of the buckle. During the installation process, by pressing the buckling piece downward, the cross bar is pressed downward, thereby controlling the opening angle of the buckle, that is, controlling the distance between the BBF tubes.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The fasteners are designed to not only connect the upper and lower steel bars to clamp the BBF pipe, but its V-shaped structure can limit the horizontal position of the BBF pipe to achieve a complete positioning effect. That is, during the construction process, the device limits the floating of the BBF pipe and ensures the quality of construction.

[0014] 2. Installation tools are provided to facilitate the installation of fasteners, save manpower and improve construction efficiency.

[0015] 3. Add cross bars on the basis of fasteners to reduce the deformation of fasteners during pouring and compaction process and improve the quality of floor slabs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Embodiment 1

[0027] A hollow floor BBF pipe positioning anti-floating device, the device is a fastener 2, such as Figure 2 As shown, the fastener 2 is formed by bending a rod into a V-shaped member. Specifically, the fastener 2 is bent three times, the fastener 2 is bent from the middle to form a V-shape, and then the end of the fastener 2 is further bent into a hook shape.

[0028] This solution can be applied as Figure 4 As shown, during the construction, a BBF tube 4, a lower steel bar 5 and an upper steel bar 6 are used. The heights of the lower steel bar 5 and the upper steel bar 6 are restricted and fixed. The BBF tube 4 is clamped between the lower steel bar 5 and the upper steel bar 6, that is, the clamped BBF tube 4 cannot float up. Figure 7 As shown, the BBF tube 4 is fixed by using a connecting member 7, specifically a rod with hooks at both ends to hook the lower steel bar 5 and the upper steel bar 6. However, this method cannot limit the horizontal position of the BBF tube 4. In this solution, the rod is replaced by a fastener 2 to limit the horizontal displacement of the BBF tube 4.

[0029] like Figure 5As shown, a quick construction tool is an installation tool 1, which includes a lower support 13 and a pressure rod 110. The lower end of the lower support 13 is slidably provided with an insertion rod 12, that is, the insertion rod 12 has the ability to slide forward and backward. A bracket 11 is provided at the upper end of one end of the insertion rod 12. The lower wall of the bracket 11 is arc-shaped, which just fits with the lower part of the fastener 2 to improve the stability of the fastener 2 during installation. The upper side wall of the front side of the lower support 13 is fixedly connected with a clamp 15, and the clamp 15 is located above the bracket 11. When the installation tool 1 is used, the fastener 2 is fixed thereon in advance, and then the opening provided on the front side of the clamp 15 clamps the upper steel bar 6, and the upper end of the fastener 2 is bent to just hook the upper steel bar 6, and subsequent operations can be performed.

[0030] like Figure 6 As shown, a support block 114 is fixedly connected to the lower back of the lower support member 13, and the end of the support block 114 is rotatably connected to the lower part of the pressure rod 110, that is, the pressure rod 110 can rotate around the end of the support block 114, and the lower end of the pressure rod 110 is rotatably connected to the end of the insertion rod 12. During the process of the upper part of the pressure rod 110 rotating backward, the lower part of the pressure rod 110 is pushed forward, that is, the insertion rod 12 moves forward, and pushes the lower part of the fastener 2 to move forward, but under the obstruction of the lower steel bar 5, the lower end of the fastener 2 is bent, as shown in FIG. Figure 1 As shown, the lower steel bar 5 is embraced, and the fastener 2 locks the lower steel bar 5 and the upper steel bar 6 in the up and down directions. At the same time, due to the V-shaped structure of the fastener 2, the middle part of the fastener 2 abuts against the side wall of the BBF tube 4, limiting the horizontal displacement of the BBF tube 4.

[0031] like Figure 6 As shown, a long hole 111 is provided at the lower end of the pressure rod 110, and a first axial pin 112 is penetrated through the end of the insertion rod 12. The first axial pin 112 and the long hole 111 are slidably matched. During the rotation of the pressure rod 110, the position of the matching point between the end of the insertion rod 12 and the pressure rod 110 will change. The structure of the long hole 111 is used to prevent the pressure rod 110 from being stuck during rotation.

[0032] A second shaft pin 113 is inserted through the rotation connection between the support block 114 and the pressure rod 110 , and the rotation connection between the support block 114 and the pressure rod 110 is achieved through the shaft pin 113 .

[0033] like Figure 5As shown, the upper end of the lower supporting member 13 is fixedly connected with a handle 18, which is a cylindrical pipe and has a grip on the upper end. The upper side wall of the handle 18 is fixedly connected with a fixing rod 19, which is fixed in a horizontal form. The fixing rod 19 fits in a through hole preset in the upper part of the pressure rod 110, and a grip is also provided on the upper side wall of the pressure rod 110. Since the moving trajectory of the pressure rod 110 is a fan-shaped structure, that is, the moving trajectory of the through hole is an arc, when the fixing rod 19 is inserted into the through hole, it is bound to cause the side wall of the fixing rod 19 and the inner wall of the through hole to fit closely, and the friction force generated also prevents the pressure rod from shaking at will. When the pressure rod 110 is used, it only needs to be pushed backward vigorously.

[0034] The front side wall of the lower support 13 is fixedly connected with a placement piece 14, and a slot is provided on the front of the placement piece 14. Two placement pieces 14 are provided and are axially symmetrically arranged. When the lower end of the fastener 2 is placed in the bracket 11, the upper part of the fastener 2 is placed in the slot, that is, the fastener 2 is fixed in the installation tool 1 for use. After the installation of the fastener 2 is completed, the installation tool 1 can be withdrawn backwards. Embodiment 2

[0035] Based on the above embodiment, this embodiment has the following differences:

[0036] Although the fastener 2 can play the role of horizontal limit of the BBF pipe 4 in the above description, the V-opening size of the fastener 2 will not be uniform during the production, transportation and installation of the fastener 2. At the same time, during the subsequent pouring and tamping construction, when the fastener 2 is deformed by force, the horizontal position of the BBF pipe will also change. Therefore, a cross bar 3 is added to the fastener 2, such as Figure 3 , and openings are provided at both ends of the cross bar 3, and the openings clamp the middle part of the fastener 2.

[0037] Correspondingly, the following structure is provided in the installation tool 1, a fixing ring 16 is provided in the middle of the front side of the lower support 13, the fixing ring 16 is provided with multiple rings, a buckling piece 17 is movably provided on the fixing ring 16, the middle part of the buckling piece 17 is a sliding rod, and pressure plates are provided at both ends of the sliding rod. When the lower end of the fastener 2 is bent and fixed, the buckling piece 17 is pressed down, and the cross bar 3 is pressed and moved downward, thereby expanding the fastener 2. It is more convenient to step on the buckling piece 17 with the foot.

[0038] In the above two embodiments, the fastener 2, the crossbar 3, the lower reinforcement 5 and the upper reinforcement 6 are all made of threaded steel bars, and during installation, the threaded surface is in contact, which has an anti-slip effect and ensures the stability of the fastener 2.

[0039] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
