[0002] Steel truss floor deck is a composite floor system that combines prefabricated steel trusses with a base plate or concrete bottom formwork, and has the dual functions of a construction formwork and a load-bearing structure. Its core feature is that it achieves rapid construction through factory-prefabricated truss structures, while improving the mechanical properties and construction efficiency of traditional cast-in-place floor slabs.

[0003] In a Chinese patent (application number: CN202010659288.9), a steel bar floor slab and aluminum formwork connection structure and its construction process are disclosed, including a steel bar truss and an aluminum formwork connected to the lower end of the steel bar truss, the steel bar truss is connected with a connection mechanism that detachably connects it to the aluminum formwork, the connection mechanism includes a fixing member fixed to the steel bar truss and a connecting member that limits the position of the aluminum formwork, a connecting groove is provided at the lower end of the fixing member, a fixing groove is provided on the top surface of the connecting groove, a connecting block is fixed at the upper end of the connecting member, the connecting block passes through the aluminum formwork and the connecting groove and is placed in the fixing groove, the connecting block rotates along the axis of the connecting member in the fixing groove, the bottom surface of the connecting block abuts against the bottom surface of the fixing groove, and an abutting block is fixed at the lower end of the connecting member, and the upper end of the abutting block abuts against the bottom surface of the aluminum formwork. By detachably connecting the steel bar truss and the aluminum formwork, the aluminum formwork will not be subjected to the tensile force applied by the steel bar when the aluminum formwork is separated from the solidified concrete, so that the aluminum formwork is not easily damaged when it is separated.

[0004] This patent and the prior art have the following technical problems in actual use: 1. The patented connection mechanism connects and separates the steel truss and the aluminum formwork through the connection block, connection groove and fixing groove. Although this part can ensure that the aluminum formwork is not subjected to excessive tension, in actual construction, it is necessary to adjust the height between the steel truss and the aluminum formwork. When adjusting the height, certain operations are required to loosen or tighten the connectors, which may increase the complexity of the construction operation. In addition, when the height needs to be adjusted, the steel truss needs to be hoisted with the help of external hoisting equipment, which is time-consuming and labor-intensive, affecting work efficiency.

[0005] 2. In this patent, after the concrete is poured on the base plate, it is usually necessary to vibrate the poured concrete in order to remove bubbles and air in the concrete and make the concrete denser. The patent itself does not have a corresponding vibration structure, so it is necessary to use the vibration equipment in the existing products. In this process, the use cost is increased and the work efficiency is also affected. Summary of the invention

[0009] Furthermore, a fixing block is fixedly connected to the outer wall of the steel bar truss, a second mounting groove is arranged on the outer wall of the fixing block, and the locking tongue assembly is arranged between the first mounting groove and the second mounting groove.

[0010] Further, the locking tongue assembly comprises two symmetrical parts, and the two symmetrical parts respectively comprise a semicircular arc plate, a semicircular tongue block, a tension spring, a first connecting rod and a second connecting rod; The two symmetrical parts are respectively installed on the inner walls of the first installation groove and the second installation groove. When the connecting frame and the steel bar truss are butt-jointed, the two symmetrical parts are locked and connected with each other.

[0011] Further, the two semicircular arc plates are respectively mounted on the inner walls of the first mounting groove and the second mounting groove, and the two second connecting rods are respectively connected to the inner walls of the first mounting groove and the second mounting groove; The two semicircular tongue blocks are rotatably connected to the inner walls of the first mounting groove and the second mounting groove respectively, and move along the inner wall of the semicircular arc plate; The first connecting rod is connected to the semicircular tongue block, and the two ends of the tension spring are rotatably connected to the outer walls of the first connecting rod and the second connecting rod respectively.

[0012] Furthermore, the airflow channel includes a cylindrical cavity and a pipe, the cylindrical cavity is installed on the inner wall of the long groove, the pipe is connected to the outer wall of the cylindrical cavity, the pipe faces the airbag, the needle is connected to one end of the pipe close to the airbag, and the exhaust port diameter of the needle is smaller than that of the pipe.

[0013] Furthermore, an exhaust port for exhausting air is provided on the outer wall of the bottom of the cylindrical cavity.

[0014] Furthermore, four chambers are arranged inside the base plate, and the driving assembly includes an impeller and an elastic shaking structure. The impeller consists of blades and a rotating shaft. The blades are arranged in an arc shape, and several of the blades are installed at one end of the rotating shaft. Several of the blades are located on the inner side of the cylindrical cavity. The airflow flowing inside the airbag is used to drive the blades. The rotating shaft of the impeller passes through the base plate and extends to the inside of the chamber and is rotatably connected. Several of the elastic shaking structures are installed on the outer wall of the rotating shaft of the impeller and are located inside the chamber.

[0015] Furthermore, the elastic shaking structure comprises a spring and an elastic ball, wherein the spring is connected to the outer wall of the rotating shaft of the impeller, and the elastic ball is installed at an end of the spring away from the rotating shaft; The height of the chamber is smaller than the width of the chamber, and the length formed by the spring and the elastic ball is greater than half of the height of the chamber.

[0016] A construction process for a steel truss floor deck, comprising the following steps: Step 1: hoist the steel truss on the upper surface of the base plate, slowly move it downward, align the positions of the fixed block and the connecting block, and lock the base plate and the steel truss through the locking tongue assembly; Step 2: pouring concrete on the upper surface of the base plate; Step 3: Apply downward pressure to both ends of the steel truss at the same time. The steel truss pushes the connecting frame, and the connecting frame pushes the airbag. The airbag has a certain elastic force, which facilitates the lifting of the connecting frame and the steel truss. Step 4: Continue to press down the steel truss and the connecting frame, so that the needle pierces the airbag, and the airflow inside the airbag pushes the impeller through the needle hole, the pipe and the cylindrical cavity; Step 5: The impeller rotates, driving the spring and the elastic ball to rotate, thereby continuously knocking the chamber of the bottom plate, causing the bottom plate to continuously vibrate, and the vibration is transmitted to the concrete from bottom to top; Step six, when the threaded holes of the inner cavity and the slider are aligned, the slider is fixed by threading bolts through the two threaded holes, thereby fixing the height position of the connecting frame and the steel truss.

[0017] The beneficial effects of the present invention are as follows: 1. The airbag of the present invention is made of natural rubber, which has high elasticity. When both ends of the steel truss are simultaneously subjected to downward pressure, the connecting frame is driven to move. At this time, due to the elasticity of the airbag itself, there is a reaction force on the connecting frame. When the height of the steel truss needs to be adjusted, the steel truss is pressed down to reduce its height. The airbag is compressible, and the connecting frame pushes the airbag to a certain extent. With the gravity of the steel truss itself, it is more labor-saving to adjust the downward pressure. Secondly, the steel truss may need to be raised in height. Due to the elastic force of the airbag, the reaction force on the connecting frame and the steel truss can make the steel truss offset part of the gravity of the steel truss when it is adjusted upward, thereby achieving a labor-saving effect in the process of lifting the steel truss, so that the steel truss can be fine-tuned conveniently. After fine-tuning, the steel truss is adjusted to the appropriate height, the height between the bottom surface of the steel truss and the upper surface of the base plate, which is about 50 mm to 100 mm, leaving a certain gap to allow vibration to be better transmitted, thereby ensuring that the concrete can vibrate evenly.

[0018] 2. In the present invention, the airbag is pushed and squeezed and punctured by the needle, and the gas released from the airbag drives the impeller to rotate. When the impeller shaft rotates, the spring and the elastic ball connected to its outer wall make circular motion. Since the length formed by the spring and the elastic ball is greater than half of the height of the chamber, and the height of the chamber is less than the width of the chamber, the elastic shaking component and the chamber are intermittently collided and vibrated. During the rotation process, the elastic ball will collide with the top or bottom inner wall of the chamber. The spring allows the elastic ball to give a certain elastic potential energy, thereby extending the duration of the elastic ball's collision with the inner wall of the chamber, continuously knocking the chamber of the bottom plate, causing the bottom plate to continuously vibrate, and the vibration is transmitted to the concrete from bottom to top, thereby helping to remove bubbles and air in the concrete and making the concrete denser. The removal of bubbles can reduce the porosity of the concrete, thereby improving its density. Through shaking, the particles inside the concrete are more evenly distributed.

[0019] 3. The present invention sets a locking tongue assembly. In the initial state, when not connected, the semicircular tongue block is in the initial position under the tension of the tension spring, and the two ends of the tension spring are respectively connected to the first connecting rod (connected to the semicircular tongue block) and the second connecting rod (connected to the inner wall of the installation groove), so that the semicircular tongue block and the semicircular arc plate have a certain relative position relationship. When the connecting frame and the steel truss are docked, one of the semicircular tongue blocks pushes the other semicircular tongue block, and the semicircular tongue blocks of the two symmetrical parts move along the inner wall of the semicircular arc plate. The two tension springs are stretched or compressed respectively, so that the two symmetrical parts are locked and connected with each other, thereby firmly connecting the connecting frame and the steel truss, thereby reducing the installation steps and improving the installation efficiency.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] A steel truss floor deck structure and its construction process according to a preferred embodiment of the present invention will be described in detail below.

[0025] Embodiment 1 like Figure 1 - Fig.12 As shown, a steel truss floor deck structure and its construction process include a bottom plate 1 and a steel truss 3, two long grooves 101 are respectively provided on the outer walls of both sides of the bottom plate 1, a connecting frame 2 for connecting with the steel truss 3 is installed on the long groove 101, and a locking tongue assembly 5 for limiting and fixing is installed between the connecting frame 2 and the steel truss 3; An inner cavity is provided at both ends of the four long slots 101, and an airbag 4 is installed on the inner wall of the inner cavity of the long slot 101, and one end of the airbag 4 is fitted with the bottom of the connecting frame 2; Four chambers 102 are arranged inside the bottom plate 1, and an impeller 6 is installed inside the end of the air flow channel away from the needle 11; An airflow channel is installed on the inner wall of the cavity in the long groove 101, and one end of the airflow channel close to the airbag 4 is connected to a needle 11 for piercing the airbag 4, and a needle hole 1101 for airflow of the airbag 4 is opened on the outer wall of the needle 11; Several driving components are arranged inside the bottom plate 1. The airflow of the airbag 4 is discharged through the airflow channel to drive the driving components. When the driving components are running, the bottom plate 1 is vibrated. The purpose of the above arrangement is that the bottom plate 1 is connected to the connecting frame 2 through the long groove 101, and then the connecting frame 2 is fixed to the steel truss 3 through the locking tongue assembly 5. The airbag 4 is pre-installed in the cavity of the long groove 101 and fits with the bottom of the connecting frame 2. The airbag 4 is in an unpressurized closed state, and the needle 11 does not penetrate the airbag 4. The airbag 4 is made of natural rubber. Natural rubber has high elasticity and can be restored to its original state within a large deformation range. At the same time, the airbag 4 has strong resistance to friction and wear, and is suitable for mechanical parts that need to run for a long time. When both ends of the steel truss 3 are simultaneously subjected to downward pressure, the connecting frame 2 is driven to move. At this time, due to the elasticity of the airbag 4 itself, there is a reaction force on the connecting frame 2. When the height of the steel truss 3 needs to be adjusted, this height adjustment: First, the steel truss 3 is pressed down to lower its height. The airbag 4 can be compressed. At the same time, the connecting frame 2 will push the airbag 4 to a certain extent. With the gravity of the steel truss 3, it is easier to adjust the downward pressure. Secondly, the steel truss 3 may need to be raised in height. Due to the elastic force of the airbag 4, the reaction force on the connecting frame 2 and the steel truss 3 can offset part of the gravity of the steel truss 3 when the steel truss 3 is adjusted upward, thereby achieving a labor-saving effect in the process of lifting the steel truss 3.

[0026] Embodiment 2, based on the above embodiment, provides a connecting frame 2 structure; like Figure 6 - Figure 8 As shown, the connecting frame 2 includes a connecting block 201, a rotating rod 202 and a slider 203, the two sliders 203 are respectively slidably connected to the inner wall of the long groove 101, the bottom ends of the two rotating rods 202 are respectively rotatably connected to the outer walls of the two sliders 203, the top ends of the two rotating rods 202 are respectively rotatably connected to the connecting block 201, the bottom ends of the rotating rods 202 are inclined toward the slider 203, and the first mounting groove 2010 is provided on one side of the connecting block 201 close to the steel bar truss 3; The inner cavity and the slider 203 are penetrated by threaded holes, and the diameters of the two threaded holes correspond to each other; The purpose of the above-mentioned arrangement is that when the connecting frame 2 is pushed downward, the bottom end of the rotating rod 202 is tilted toward the slider 203 to form a certain tilt angle, so that it is convenient for the connecting block 201 to push the rotating rod 202. The rotating rod 202 rotates and deflects after being subjected to force, thereby pushing the slider 203. The slider 203 moves along the inner wall of the long groove 101. When the threaded hole of the slider 203 corresponds to the threaded hole of the inner cavity, before this, the airbag 4 has been punctured by the needle 11 to release gas and collapse, thereby facilitating the adjustment of the position of the slider 203.

[0027] Embodiment 3, based on the above embodiment, provides a structure of a steel bar truss 3; like Figure 3 - Figure 5 As shown, a fixing block 301 is fixedly connected to the outer wall of the steel truss 3, a second mounting groove 3010 is arranged on the outer wall of the fixing block 301, and the locking tongue assembly 5 is arranged between the first mounting groove 2010 and the second mounting groove 3010; The purpose of the above arrangement is that the locking tongue assembly 5 is arranged between the first installation groove 2010 and the second installation groove 3010 to fix the steel bar truss 3 and the connecting frame 2.

[0028] Embodiment 4, based on the above embodiment, provides a structure of a locking tongue assembly 5; like Figure 3 - Figure 5 As shown, the locking tongue assembly 5 includes two symmetrical parts, which respectively include a semicircular arc plate 501, a semicircular tongue block 502, a tension spring 503, a first connecting rod 504 and a second connecting rod 505; The two symmetrical parts are respectively installed on the inner walls of the first installation groove 2010 and the second installation groove 3010. When the connecting frame 2 and the steel bar truss 3 are butt-jointed, the two symmetrical parts are locked and connected with each other. The purpose of the above arrangement is to provide a convenient fixing method for the structural composition of the locking tongue assembly 5 and the connecting frame 2 and the steel truss 3.

[0029] The two semicircular arc plates 501 are respectively installed on the inner walls of the first installation groove 2010 and the second installation groove 3010, and the two second connecting rods 505 are respectively connected to the inner walls of the first installation groove 2010 and the second installation groove 3010; The two semicircular tongue blocks 502 are rotatably connected to the inner walls of the first mounting groove 2010 and the second mounting groove 3010, respectively, and move along the inner wall of the semicircular arc plate 501; The first connecting rod 504 is connected to the semicircular tongue block 502, and the two ends of the tension spring 503 are rotatably connected to the outer walls of the first connecting rod 504 and the second connecting rod 505 respectively; The purpose of the above arrangement is that in the initial state, when not connected, the semicircular tongue block 502 is in the initial position under the tension of the tension spring 503, and the two ends of the tension spring 503 are respectively connected to the first connecting rod 504 (connected to the semicircular tongue block 502) and the second connecting rod 505 (connected to the inner wall of the mounting groove), so that the semicircular tongue block 502 and the semicircular arc plate 501 have a certain relative position relationship. When the connecting frame 2 and the steel truss 3 are docked, one of the semicircular tongue blocks 502 pushes the other semicircular tongue block 502, and the semicircular tongue blocks 502 of the two symmetrical parts move along the inner wall of the semicircular arc plate 501, and the two tension springs 503 are respectively stretched or compressed, so that the two symmetrical parts are locked and connected with each other, thereby firmly connecting the connecting frame 2 and the steel truss 3 together.

[0030] Embodiment 5, based on the above embodiment, provides a structure of an air flow channel; like Fig.10 - Fig.12 As shown, the air flow channel includes a cylindrical cavity 9 and a pipe 10, the cylindrical cavity 9 is installed on the inner wall of the long groove 101, the pipe 10 is connected to the outer wall of the cylindrical cavity 9, the pipe 10 faces the airbag 4, the needle 11 is connected to one end of the pipe 10 close to the airbag 4, and the exhaust port diameter of the needle 11 is smaller than the pipe 10; The purpose of the above arrangement is that after the airbag 4 is pressurized, the gas enters the pipe 10 through the needle 11 and then flows into the cylindrical cavity 9. Since the exhaust port diameter of the needle 11 is smaller than the pipe 10, the gas will have a certain pressure change when entering the pipe 10.

[0031] Embodiment 6, based on the above embodiment, provides a structure of an exhaust port 901; like Fig.12 As shown, an exhaust port 901 for exhausting air is provided on the bottom outer wall of the cylindrical cavity 9; The purpose of the above arrangement is to allow the gas to push the blades and then be discharged from the exhaust port 901 along the arc-shaped inner wall of the cylindrical cavity 9, so that the airflow forms gas kinetic energy, which is converted into mechanical energy when pushing the blades.

[0032] Embodiment 7, based on the above embodiment, provides a driving assembly; like Fig.10 As shown, four chambers 102 are arranged inside the bottom plate 1, and the driving assembly includes an impeller 6 and an elastic shaking structure. The impeller 6 is composed of blades and a rotating shaft. The blades are arranged in an arc shape, and a plurality of blades are installed at one end of the rotating shaft. A plurality of blades are located inside the cylindrical cavity 9. The airflow flowing inside the airbag 4 is used to drive the blades. The rotating shaft of the impeller 6 passes through the bottom plate 1 and extends to the inside of the chamber 102 and is rotatably connected. A plurality of elastic shaking structures are installed on the outer wall of the rotating shaft of the impeller 6 and are located inside the chamber 102. The purpose of the above arrangement is that when both ends of the steel truss 3 are simultaneously subjected to downward pressure, the connecting frame 2 is driven to move, squeezing the bottom airbag 4, and the airbag 4 contacts the needle 11 after being compressed, and the needle 11 penetrates the airbag 4, and the compressed gas enters the airflow channel through the needle hole 1101, forming a directional airflow; When the gas flows in the cylindrical cavity 9, it will impact the blades of the impeller 6. The blades are set in an arc shape, so that the force points of the airflow are more concentrated, thereby pushing the blades faster, converting the kinetic energy of the gas into mechanical energy, driving the shaft of the impeller 6 to rotate rapidly, and at the same time driving the elastic shaking structure to perform circular motion. During this process, the elastic shaking structure collides and cooperates with the chamber 102, thereby causing the bottom plate 1 to vibrate.

[0033] Embodiment 8, based on the above embodiment, provides an elastic shaking structure; like Fig.10 As shown, the elastic shaking structure includes a spring 7 and an elastic ball 8, the spring 7 is connected to the outer wall of the rotating shaft of the impeller 6, and the elastic ball 8 is installed at one end of the spring 7 away from the rotating shaft; The height of the chamber 102 is smaller than the width of the chamber 102 , and the length formed by the spring 7 and the elastic ball 8 is greater than half of the height of the chamber 102 ; The purpose of the above arrangement is that when the impeller 6 shaft rotates, the spring 7 and the elastic ball 8 connected to its outer wall make a circular motion. Since the length formed by the spring 7 and the elastic ball 8 is greater than half of the height of the chamber 102, and the height of the chamber 102 is less than the width of the chamber 102, the elastic ball 8 and the chamber 102 are intermittently collided and vibrated, and the vibration frequency is positively correlated with the rotation speed of the impeller 6. During the rotation process, the elastic ball 8 will collide with the top or bottom inner wall of the chamber 102. The spring 7 allows the elastic ball 8 to give a certain elastic potential energy, thereby extending the duration of the collision of the elastic ball 8 with the inner wall of the chamber 102, and continuously knocking the chamber 102 of the bottom plate 1 causes the bottom plate 1 to vibrate. The vibration is transmitted to the concrete from bottom to top, which can help remove bubbles and air in the concrete and make the concrete more dense. The removal of bubbles can reduce the porosity of the concrete, thereby improving its density. Through shaking, the particles inside the concrete are more evenly distributed.

[0034] When in use, the steel truss 3 is hoisted on the upper surface of the bottom plate 1 and slowly moved downward, and the positions of the fixing block 301 and the connecting block 201 are aligned. When the steel truss 3 is docked with the connecting frame 2, the fixing block 301 and the second mounting groove 3010 on the steel truss 3 correspond to the connecting block 201 and the first mounting groove 2010 on the connecting frame 2. When the two are docked, the connection and fixation are achieved through the locking tongue assembly 5; In the initial state, when not connected, the semicircular tongue block 502 is in the initial position under the tension of the tension spring 503, and the two ends of the tension spring 503 are respectively connected to the first connecting rod 504 (connected to the semicircular tongue block 502) and the second connecting rod 505 (connected to the inner wall of the installation groove), so that the semicircular tongue block 502 and the semicircular arc plate 501 have a certain relative position relationship. When the connecting frame 2 and the steel truss 3 are docked, one of the semicircular tongue blocks 502 pushes the other semicircular tongue block 502, and the semicircular tongue blocks 502 of the two symmetrical parts move along the inner wall of the semicircular arc plate 501, and the two tension springs 503 are respectively stretched or compressed, so that the two symmetrical parts are locked and connected with each other, thereby firmly connecting the connecting frame 2 and the steel truss 3 together; The slider 203 of the connecting frame 2 can slide in the long groove 101. When the connecting block 201 moves downward, the connecting block 201 pushes the slider 203 to slide in the long groove 101 through the rotating rod 202, squeezing the airbag 4. The airbag 4 has a certain elastic force, and it is convenient to lift the connecting frame 2 and the steel truss 3 again. After the airbag 4 is pressurized, the gas enters the pipe 10 through the needle 11, and then flows into the cylindrical cavity 9. Since the exhaust port diameter of the needle 11 is smaller than the pipe 10, the gas will have a certain pressure change when entering the pipe 10. The cylindrical cavity 9 is outside a plurality of blades. When the gas flows in the cylindrical cavity 9, it will impact the blades of the impeller 6. The blades are arranged in an arc shape, so that the airflow force point is more concentrated, so that the blades can be pushed faster, and the kinetic energy of the gas is converted into mechanical energy, driving the rotating shaft of the impeller 6 to rotate rapidly; When the impeller 6 shaft rotates, the spring 7 and the elastic ball 8 connected to its outer wall make a circular motion. Since the length formed by the spring 7 and the elastic ball 8 is greater than half of the height of the chamber 102, and the height of the chamber 102 is less than the width of the chamber 102, the elastic ball 8 will collide with the top or bottom inner wall of the chamber 102 during the rotation. The spring 7 allows the elastic ball 8 to give a certain elastic potential energy, thereby extending the duration of the collision of the elastic ball 8 with the inner wall of the chamber 102, and continuously knocking the chamber 102 of the bottom plate 1 causes the bottom plate 1 to continuously vibrate. The vibration is transmitted to the concrete from bottom to top, which can help remove bubbles and air in the concrete and make the concrete more dense. The removal of bubbles can reduce the porosity of the concrete, thereby improving its density. Through shaking, the particles inside the concrete are more evenly distributed.
