Description

Technical Field

[0001] The present invention relates to the technical field of building component tests, and particularly relates to a horizontal combustion furnace for building components. Background Art

[0002] With the development of society, the material wealth and population density are continuously increasing, and the frequency of fires and the resulting hazards are becoming more and more serious. Among them, the flammability of building materials is one of the important factors of fire risk. Therefore, using materials with higher fire resistance has become a key strategy to reduce fire hazards. Moreover, before building materials are put into use, their fire resistance must be tested first.

[0003] The fire resistance of building components is usually verified by a test combustion furnace. In the fire test, according to the temperature and pressure conditions in the standard, a fire environment is simulated in the test furnace, and indicators such as the integrity and heat insulation of the building components are analyzed to evaluate their fire resistance. The test specimens are generally horizontal components or vertical components. Among them, horizontal components are mostly suspended during actual building use, and their horizontal length is relatively long. Therefore, the fire resistance of the middle part under pressure is related to the safety of the entire building.

[0004] The existing test combustion furnaces generally have the following problems when conducting horizontal component tests: (1) Since the horizontal component specimens are long strips, their positions and angles during the falling process and after falling into the furnace body are relatively random, and they cannot be effectively adjusted, placed, and fixed. Moreover, during the test process, the pressure-bearing environment during actual use of the horizontal components cannot be accurately simulated, resulting in inaccurate test results; (2) After the test is completed, the temperature in the furnace body is still relatively high. Therefore, the remains of the horizontal component specimens in the furnace cannot be cleaned up in a timely, rapid, and effective manner, so continuous tests cannot be carried out, resulting in high test energy consumption. Summary of the Invention

[0005] The purpose of the present invention is to provide a horizontal combustion furnace for building components, which solves the problems that the existing combustion furnaces for horizontal component specimens cannot effectively adjust, place, and fix horizontal components, cannot accurately simulate the pressure-bearing environment during actual use of horizontal components, and cannot clean up the test remains in a timely, rapid, and effective manner.

The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0033] Please refer to Figures 1 to 10 , an embodiment of the present invention provides a horizontal combustion furnace for building components, including: a furnace body 1, the top of the furnace body 1 is open, and a plurality of burners 2 and a plurality of infrared thermometers (not shown in the figure) are provided on the side wall of the furnace body 1. A loading platform 10 is horizontally arranged in the furnace body 1; secondly, a loading plate 20, the loading plate 20 is detachably laid on the loading platform 10, the loading plate 20 is used for loading component specimens, and the loading plate 20 is tightly spliced by a plurality of single plates 201. Adjacent two of the single plates 201 are hinged by a hinge shaft 202 so that the loading plate 20 can be bent into an arc-shaped plate. Two of the loading plates 20 located at the edge are respectively provided with lifting lugs 21; thirdly, a transfer mechanism, the transfer mechanism includes a translation frame 70, a longitudinal movement frame 71 and a crane 72. The translation frame 70 is slidably connected to the ground so that the translation frame 70 can move above the furnace body 1 along the X-axis direction. The longitudinal movement frame 71 is arranged on the translation frame 70, and the crane 72 is slidably connected to the longitudinal movement frame 71 so that the crane 72 can move along the Y-axis direction. The hook of the crane 72 can be lifted and lowered along the Z-axis direction. The X-axis, Y-axis, and Z-axis are perpendicular to each other in pairs. The transfer mechanism is used to transfer component specimens to the loading plate 20, and the crane 72 can be detachably hooked with the lifting lug 21; fourthly, a clamping mechanism, the clamping mechanism includes two pairs of clamping seats 30 and a driving component. The clamping seats 30 are slidably arranged along the Y-axis direction so that each pair of the clamping seats 30 can approach or move away from each other along the Y-axis direction. The two pairs of clamping seats 30 are symmetrically arranged on both sides of the loading platform 10 in the X-axis direction. The clamping seats 30 are used to clamp the ends of the component specimens in the width direction, and the driving component can make the clamping seats 30 slide directionally; fifthly, a pressing mechanism, the pressing mechanism includes a pressing beam 40 and a plurality of hydraulic telescopic columns 60. The pressing beam 40 is horizontally arranged above the furnace body 1 along the X-axis direction and is slidably connected to the furnace body 1 along the Y-axis direction. All the hydraulic telescopic columns 60 are vertically arranged at equal intervals at the bottom of the pressing beam 40. The hydraulic telescopic columns 60 are used to press down the component specimens.

[0034] A horizontal combustion furnace for building components provided by the present invention is equipped with a furnace body 1, and a plurality of burners 2 and a plurality of infrared thermometers are arranged on its side wall to enable the combustion furnace to have basic experimental conditions. The top surface of the furnace body 1 is provided with an open mouth, and on this basis, a transfer mechanism is arranged, which includes a translation frame 70, a longitudinal movement frame 71 and a crane 72. The translation frame 70 is located directly above the top of the furnace body 1 and is slidably connected to the ground along the X-axis direction. The longitudinal movement frame 71 is installed on the translation frame 70 along the Y-axis direction, and the crane 72 is slidably connected to the longitudinal movement frame 71 along the Y-axis direction. As a result, the crane 72 can perform independent X-axis direction movement and Y-axis direction movement on the top of the furnace body 1. Combining the crane 72 that can move in the Z-axis direction by itself, the crane 72 is used to hoist the specimen so that the specimen can be transported from the outside of the furnace body 1 to the inside of the furnace body 1 and perform precise displacement inside the furnace body 1. On this basis, by arranging a bearing platform 10 and detachably laying a bearing plate 20 on the bearing platform 10 to bear the specimen hoisted into the furnace body 1 by the crane 72, so that the specimen horizontally falls on the bearing plate 20. The bearing plate 20 is composed of multiple single plates 201 axially hinged, and lifting lugs 21 are arranged on the two bearing plates 20 at the edge. After the test is completed, the hook of the crane 72 is detachably hooked and lifted with the lifting lug 21, so that the bearing plate 20 rises and gradually bends into an arc-shaped plate, so as to scoop up the specimen debris located on it until the bearing plate 20 is lifted out from the top of the furnace body 1. Then the bearing plate 20 is tilted, and the specimen debris it bears can be poured out. After that, the bearing plate 20 is reset, and a new specimen can be lifted in again for continuous testing, thus effectively saving energy. On this basis, by arranging a clamping mechanism, which includes two pairs of symmetrically arranged clamping seats 30 and a driving component, the driving component is used to drive the clamping seats 30 to move directionally, so that each pair of clamping seats 30 can approach or move away from each other, and the two pairs of clamping seats 30 move symmetrically and synchronously. The two pairs of clamping seats 30 are simultaneously close to each other to gradually push and clamp the specimen from both ends to fix it, so that the specimen can be effectively placed and fixed. By arranging a pressurizing mechanism, which includes a pressurizing beam 40 to provide structural support, and a plurality of hydraulic telescopic columns 60 are vertically arranged below the pressurizing beam 40, and the longitudinally pressed specimen is pressed by it to accurately simulate the pressure borne by the specimen during actual use. Through the mutual cooperation of the above various features, the horizontal combustion furnace for building components can solve the problems that the existing horizontal component specimen combustion furnace cannot effectively adjust, place and fix horizontal components, cannot accurately simulate the pressure-bearing environment during the actual use of horizontal components, and cannot clean the test debris in a timely, rapid and effective manner.

[0035] Please refer to Figures 7 to 10, To prevent the hydraulic telescopic column 60 from shifting or tilting due to specimen deformation during pressurization, a sleeve 50 is coaxially sleeved outside the hydraulic telescopic column 60. Adjacent sleeves 50 are fixedly connected by multiple synchronous beams 51. The two sleeves 50 on both sides are fixedly connected to the pressurizing beam 40 by multiple synchronous beams 51.

[0036] By arranging the sleeve 50 to be coaxially sleeved outside the hydraulic telescopic column 60, and fixedly connecting adjacent sleeves 50 by multiple synchronous beams 51, and fixedly connecting the sleeves 50 on both sides to the pressurizing beam 40 by synchronous beams 51, the structure of the sleeves 50 on both sides is fixed by the pressurizing beam 40 and the synchronous beams 51, and the structure of adjacent sleeves 50 is fixed by the synchronous beams 51, so that all the sleeves 50 are fixed as a whole and fixed to the pressurizing beam 40 as a whole, and thus all the hydraulic telescopic columns 60 are fixed as a whole. When one of the hydraulic telescopic columns 60 is offset due to specimen deformation and is about to tilt, its sleeve 50 will be pulled by the sleeves 50 on both sides through the synchronous beam 51, thereby restricting its tilting.

[0037] To facilitate the fixed connection between the synchronous beam 51 and the sleeve 50, a plurality of holding rings 52 are coaxially and detachably sleeved outside the sleeve 50; the end of the synchronous beam 51 is fixedly connected to the holding ring 52.

[0038] During installation, the holding ring 52 is sleeved outside the sleeve 50 by sleeving, and the synchronous beam 51 fixedly connected to the holding ring 52 can be fixedly connected to the sleeve 50.

[0039] To prevent the holding ring 52 from rotating relative to the sleeve 50, resulting in uneven force or incorrect force angle on the synchronous beam 51, a plurality of limiting grooves 503 are opened on the outer wall of the sleeve 50 along the vertical direction. The top of the limiting groove 503 is penetrated and the bottom is closed; a plurality of limiting blocks 521 are radially protruded from the inner wall of the holding ring 52, and the limiting blocks 521 correspond to the limiting grooves 503 one by one and are in sliding fit.

[0040] To optimize the arrangement of the synchronous beam 51 to optimize the force, 3 holding rings 52 are coaxially and equidistantly sleeved outside each sleeve 50, and one synchronous beam 51 is connected to each of the opposite sides of each holding ring 52; the synchronous beams 51 connected to the holding rings 52 above and below are tangent to the outer wall of the holding ring 52; the synchronous beam 51 connected to the middle holding ring 52 extends along the radial direction of the holding ring 52; the vertical projection intersection of the 3 synchronous beams 51 stacked in the vertical direction is penetrated by a vertically arranged pin shaft 53.

[0041] Please refer to Figure 3 , Figure 4 and Figure 6, To further explain the specific structure of the driving component, the driving component includes a motor 31, a double-headed screw 32, and a pair of moving beams 33; the thread directions at both ends of the double-headed screw 32 are opposite, the double-headed screw 32 is horizontally rotatably arranged on the bearing platform 10 along the Y-axis direction, one end of the double-headed screw 32 is in transmission connection with the motor 31, and the motor 31 is fixedly connected to the bearing platform 10; both of the two moving beams 33 are horizontally arranged along the X-axis direction, and are respectively slidably connected to the bearing platform 10 along the Y-axis direction, and the two moving beams 33 are respectively screwed to both ends of the double-headed screw 32; a clamping seat 30 is fixedly connected to each end of each moving beam 33, and each pair of clamping seats 30 are respectively located at the same-direction ends of the two moving beams 33.

[0042] With the above arrangement, the motor 31 drives the double-headed screw 32 to rotate, thereby driving the two moving beams 33 to move synchronously and approach each other, thereby driving the two pairs of clamping seats 30 to move synchronously and approach each other, so as to respectively push, straighten and clamp the two ends of the specimen.

[0043] Please refer to Figure 3 and Figure 4 , To limit the position of the bearing plate 20, the top surface of the bearing platform 10 includes a support area 11 in the middle and a mounting area 12 at the edge. Both the support area 11 and the mounting area 12 are set as horizontal planes, and the set height of the support area 11 is lower than that of the mounting area 12, so as to form a limit groove directly above the support area. The bearing plate 20 is detachably laid in the limit groove, so that the top surface of the bearing plate 20 is flush with the mounting area 12; the clamping seat 30 is slidably arranged in the mounting area 12.

[0044] By setting the support area 11 and the mounting area 12, the support area 11 is located in the middle and the mounting area 12 is located at the edge. The two ends of the specimen are placed on the mounting area 12, and the middle part is located in the support area 11, and different environmental conditions are given respectively to simulate the environment in actual buildings where the two ends of the horizontal specimen are fixedly connected and the middle part bears pressure and load; by setting the height difference between the support area 11 and the mounting area 12 to form a limit groove, the bearing plate 20 can be detachably laid in the limit groove to limit the position of the bearing plate 20 and prevent it from slipping unnecessarily.

[0045] In order to reduce the weight of the bearing platform 10 while ensuring its structural performance, a groove is dug in the support area 11 in the vertical direction. A plurality of transverse plates 112 and longitudinal plates 113 are vertically inserted into the groove. The transverse plates 112 and the longitudinal plates 113 are perpendicularly inserted to divide the groove into a plurality of cuboid weight-reducing grooves 111. The top surface of the transverse plate 112 or the longitudinal plate 113 is flush with the support area 11. A hydraulic telescopic rod 13 is vertically inserted into the weight-reducing groove 111. When the hydraulic telescopic rod 13 is in the natural state, the top end of the hydraulic telescopic rod 13 is flush with the support area 11.

[0046] Through the above settings, while forming uniformly arrayed weight-reducing grooves 111, the structural performance inside the platform base 10 is effectively guaranteed to prevent the support area 11 from being compressed and collapsing. By setting the hydraulic telescopic rod 13, elastic support is provided to the bearing plate 20 to a certain extent.

[0047] In order to further position-limit the limiting plate 20, a plurality of first limiting piles 203 protrude vertically from the bottom surface of the two single plates 201 located at the edge. The first limiting piles 203 are used to be inserted into the weight-reducing grooves 111. A plurality of second limiting piles 205 are provided below the single plate 201. The second limiting piles 205 correspond to the hydraulic telescopic rods 13 one by one. When the second limiting piles 205 are inserted into the corresponding weight-reducing grooves 111, the corresponding hydraulic telescopic rods 13 are in a compressed state. A sealing strip 204 is provided at the joint of the bottom surface of the single plate 201. The sealing strip 204 is connected to the edge of the single plate 201. When the bearing plate 20 is an arc-shaped plate, the gap between the bottoms of two adjacent single plates 201 is sealed by the sealing strip 204.

[0048] By setting the first limiting piles 203 and the second limiting piles 205, the two sides of the laid bearing plate 20 are positioned and limited to further prevent it from slipping during use. By setting the sealing strip 204, it is prevented that the sample debris leaks from the hinge joint when the bearing plate 20 bends.

[0049] Please refer to Figure 1 and Figure 2, in order to further explain the specific structures of the translation frame 70 and the longitudinal movement frame 71, the translation frame 70 includes a translation beam 701 and four legs 702; the translation beam 701 is horizontally arranged directly above the specimen combustion furnace along the Y-axis direction, the length of the translation beam 701 matches the furnace width of the furnace body 1 along the Y-axis direction, the four legs 702 are respectively fixedly connected to the four corners of the translation beam 701, and the bottom ends of the legs 702 are slidably connected to the ground along the X-axis direction; the legs 702 are inclined so that a trapezoidal surface can be formed by enclosing the translation beam 701 and any two of the legs 702; the longitudinal movement frame 71 includes a longitudinal movement beam 711 and a longitudinal movement slide 712, the longitudinal movement beam 711 is horizontally arranged along the Y-axis direction and is inserted into the translation beam 701 in a cross shape; the longitudinal movement slide 712 is slidably connected to the bottom of the longitudinal movement beam 711, and the crane 72 is fixedly connected to the longitudinal movement slide 712.

[0050] Through the above settings, the translation beam 701 can be horizontally spanned above the furnace body 1, the four legs 702 can effectively support the translation beam 701 without hindering the furnace body 1, and the translation beam 701 can be moved outside the furnace body 1 to hoist the specimen located outside the furnace body 1, and hoist the bearing plate 20 outside the furnace body 1 to pour the specimen debris thereon.
