[0002] In the field of building construction, steel pipe web truss prestressed composite floor is widely used in various construction projects due to its good structural performance and high construction efficiency. However, there are many problems in transporting steel pipe web truss prestressed composite floor.

[0003] The prestressed composite floor is usually composed of a prestressed bottom plate, an upper chord rib and a hollow steel pipe web truss fixed between them, and a plurality of prestressed steel bars are inserted and fixed on the surface of the prestressed bottom plate. During transportation, a plurality of prestressed composite floors need to be stacked to improve transportation efficiency and reduce transportation cost. However, the existing transportation method lacks effective auxiliary structure, resulting in many problems during stacking and transportation.

[0004] On the one hand, the stacked prestressed composite floor is prone to swing forward and backward, and lacks effective limiting and supporting devices, which not only increases the safety hazards during transportation, but also may cause damage to the floor and affect the engineering quality. On the other hand, during stacking, the lower prestressed composite floor lacks reliable installation and reinforcement measures, and the impact force generated when the upper floor is placed and the jolt during transportation can easily cause the connection part of the lower floor to loosen, even causing the auxiliary structure to fall off, further affecting the transportation safety and floor quality. In addition, the stacked auxiliary structures are also prone to misalignment and jolt, and lack effective fixing methods, which also brings inconvenience to transportation. Moreover, during hoisting, additional hoisting hangers are needed, increasing the construction cost and operation complexity; after transportation is completed, the disassembled auxiliary structures are stacked randomly, which is not convenient for management and reuse.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme of the present application clear and complete, and the advantages more clear and obvious, the embodiments of the present application are further described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present application, rather than all the embodiments, and are only used to explain the embodiments of the present application, and do not limit the embodiments of the present application, and all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1 to 7This invention provides a technical solution: an auxiliary structure for transporting prestressed composite floor slabs with steel pipe web trusses, comprising a pad 1, which overlaps a prestressed base slab 2. Multiple upper chord ribs 202 are provided above the prestressed base slab 2. Hollow steel pipe web trusses 203 are fixed between the upper chord ribs 202 and the prestressed base slab 2. Multiple prestressed steel bars 201 are inserted and fixed to the surface of the prestressed base slab 2. A reserved groove 101 is formed on the surface of the pad 1, and the reserved groove 101 is fitted onto the upper chord ribs 203. On the top surface of the pad 1, an overlap groove 102 is provided. When two prestressed base plates 2 are stacked, one prestressed base plate 2 is inserted into the overlap groove 102 of the pad 1 on top of the other prestressed base plate 2. The reserved groove 101 is a "T" shaped groove. The reserved groove 101 corresponds one-to-one with the upper chord rib 202. Both sides of the pad 1 are provided with installation grooves 105. A connecting screw 5 is screwed into the inside of the installation groove 105. One end of the connecting screw 5 extends into the reserved groove 101 and is screwed onto the surface of the upper chord rib 202.

[0033] The purpose of installing the pad 1 on the prestressed base plate 2 is to support the prestressed base plate 2 stacked on top and to limit the prestressed base plate 2 in the corresponding overlap groove 102, so as to prevent the prestressed base plate 2 from swinging back and forth. When installing the pad 1, align the reserved groove 101 on the surface of the pad 1 with the corresponding upper chord rib 202, push the pad 1 a certain distance towards the middle of the prestressed base plate 2, and then tighten the connecting screw 5 to clamp the side wall of the upper chord rib 202, or directly screw the connecting screw 5 onto the side wall of the upper chord rib 202 to brake the pad 1 onto the upper chord rib 202. Similarly, install the pad 1 at the other end of the prestressed base plate 2. It should be noted that when multiple prestressed base plates 2 are stacked, a wooden pad is added to the bottom of the bottommost prestressed base plate 2, or a pad 1 without the splicing insert 6 is added.

[0034] In order to achieve the installation and reinforcement of the lower prestressed base slab 2 while stacking the upper prestressed base slab 2, the following method is proposed:

[0035] The top surface of the reserved groove 101 is provided with a notch 104, and the top surface of the notch 104 is provided with a through opening 103. The opening size of the through opening 103 is smaller than the top surface size of the notch 104. A rubber sheet 3 is fixed between two parallel sidewalls of the notch 104. A clamping block 4 is inserted into the through opening 103. The height of the clamping block 4 is greater than the depth of the through opening 103. The bottom surface of the clamping block 4 is fixed to the top surface of the rubber sheet 3. When the rubber sheet 3 is in the initial state, the rubber sheet 3 supports the clamping block 4, and the top of the clamping block 4 extends out of the through opening 103. After the prestressed base plate 2 is inserted into the corresponding reserved groove 101, the prestressed base plate 2 pushes the clamping block 4 downward, and the clamping block 4 retracts into the through opening 103. The clamping block 4 clamps the rubber sheet 3 between the upper chord rib 202 and the clamping block 4 to produce elastic deformation.

[0036] After the cushion plate 1 is placed on the prestressed bottom plate 2 of the bottom, when the prestressed bottom plate 2 of the upper part is hoisted and falls into the lap joint groove 102 on the top surface of the bottom cushion plate 1, due to the self weight of the prestressed bottom plate 2, the prestressed bottom plate 2 is pressed downward to the clamping block 4 to retract into the through hole 103, and the clamping block 4 presses the rubber sheet 3 to adhere to the surface of the upper chord rib 202 of the bottom, so that the upper chord rib 202 of the bottom is connected to the cushion plate 1 of the bottom, and even if the connecting screw 1 5 is loose, the phenomenon that the cushion plate 1 falls off the prestressed bottom plate 2 will not occur.

[0037] In order to realize the fixation of the stacked cushion plate 1, the following is proposed:

[0038] The top surface of the cushion plate 1 is provided with an edge groove 107 and an abutting insertion groove 109 at both ends, and the bottom surface of the cushion plate 1 is fixed with a splicing insertion plate 6. After two cushion plates 1 are stacked, the splicing insertion plate 6 at the bottom of one cushion plate 1 is inserted into the abutting insertion groove 109 on the top surface of the other cushion plate 1, and the edge groove 107 is screwed with a connecting screw 2 7, and the connecting screw 2 7 penetrates the splicing insertion plate 6. The width of the abutting insertion groove 109 is equal to the thickness of the splicing insertion plate 6, and screw holes 1 10 are formed on the two parallel side walls of the abutting insertion groove 109, and screw holes 2 601 are formed on the surface of the splicing insertion plate 6. After two cushion plates 1 are stacked, the splicing insertion plate 6 is inserted into the corresponding abutting insertion groove 109, the screw holes 1 10 and the screw holes 2 601 are corresponded, and the connecting screw 2 7 penetrates the two screw holes 1 10 and the screw holes 2 601.

[0039] After two prestressed bottom plates 2 provided with the cushion plate 1 are stacked, the upper prestressed bottom plate 2 is pressed between the two cushion plates 1, at this time the splicing insertion plate 6 is inserted into the corresponding abutting insertion groove 109, and the connecting screw 2 7 penetrates the screw holes 1 10 and the screw holes 2 601, so as to fix the splicing insertion plate 6 in the abutting insertion groove 109, thereby avoiding the misalignment and jolt between the stacked cushion plates 1.

[0040] In order to realize the use of the cushion plate 1 as a hoisting sling, the following is proposed:

[0041] The two ends of the cushion plate 1 are provided with hoisting through holes 106; the hoisting through holes 106 are long circular openings, and the top surface of the edge groove 107 is provided with two accommodation grooves 108 which are communicated with the hoisting through holes 106; after the hoisting rope is passed through the hoisting through holes 106 and lapped, the rope body of the hoisting rope is pulled upward, at this time the rope body at the node of the hoisting rope is in the accommodation groove 108.

[0042] In order to realize the neat stacking of the disassembled cushion plate 1, the following is proposed:

[0043] A plurality of cushion plates 1 are stacked and connected and then placed on the ground, and a plurality of groups of stacked and fixed cushion plates 1 are placed on the ground; or a plurality of stacked and connected cushion plates 1 are vertically placed against a wall.

[0044] Auxiliary structure for transporting steel pipe web truss prestressed composite floor

[0045] Align the "T" shaped reserved slot 101 on the surface of the base plate 1 with the corresponding top chord rib 202 on the prestressed bottom plate 2. Push the base plate 1 towards the middle of the prestressed bottom plate 2 for a distance. Screw the connecting screw one 5 inside the installation slot 105 on both sides of the base plate 1, so that one end of the connecting screw one 5 extends into the reserved slot 101 and is screwed on the surface of the top chord rib 202, or directly screw the connecting screw one 5 on the side wall of the top chord rib 202, to realize the braking of the base plate 1 on the top chord rib 202. Install the base plate 1 on the other end of the prestressed bottom plate 2 in the same way. When multiple prestressed bottom plates 2 are stacked, add a base plate 1 without the installation of the splicing plug-in plate 6 at the bottom of the lowest prestressed bottom plate 2. When stacking the upper prestressed bottom plate 2, reinforce the installation of the lower prestressed bottom plate 2: hoist the upper prestressed bottom plate 2 and drop it into the lap joint slot 102 on the top surface of the bottom base plate 1. Because the self weight of the prestressed bottom plate 2 is large, it extrudes and clamps the block 4, so that the block 4 is retracted into the through hole 103, and at the same time the block 4 extrudes the rubber sheet 3 to adhere to the surface of the bottom top chord rib 202, and the rubber sheet 3 deforms elastically, realizing the reinforcement and connection of the bottom top chord rib 202 on the bottom base plate 1. Even if the connecting screw one 5 is loose, the base plate 1 will not fall off from the prestressed bottom plate 2.

[0046] Stack two prestressed bottom plates 2 with base plates 1 installed, and press the upper prestressed bottom plate 2 between the two base plates 1. At this time, the splicing plug-in plate 6 at the bottom of one base plate 1 is inserted into the butt joint slot 109 on the top surface of the other base plate 1. Pass the connecting screw two 7 through the edge slot 107 and through the splicing plug-in plate 6. Because the two parallel distributed side walls of the butt joint slot 109 are both provided with screw holes one 110, and the surface of the splicing plug-in plate 6 is provided with screw holes two 601, after the two base plates 1 are stacked, the screw holes one 110 and the screw holes two 601 correspond, the connecting screw two 7 penetrates the two screw holes one 110 and the screw holes two 601, realizing the fixation of the splicing plug-in plate 6 in the butt joint slot 109, avoiding the misalignment and jolt between the stacked base plates 1.

[0047] When the base plate 1 is used as a hoisting sling, the hoisting rope is lapped after passing through the hoisting through hole 106 at both ends of the base plate 1. Pull the rope body of the hoisting rope upwards, and at this time the rope body at the node of the hoisting rope is in the gap slot 108 on the top surface of the edge slot 107.

[0048] Stacking of the disassembled base plate 1: multiple stacked and connected base plates 1 can be placed flat on the ground. Multiple stacked and connected base plates 1 can also be placed vertically against the wall.

[0049] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
