Description

Technical Field

[0001] The invention relates to the technical field of composite board installation construction equipment, and specifically proposes a quick leveling device for composite board installation. Background Art

[0002] Composite slabs, also known as combined slabs or precast composite slabs, are structural members formed on-site by combining precast components and cast-in-place concrete. They are usually used in the construction of floor and roof panels of buildings. Composite slabs combine the advantages of precast components and cast-in-place concrete. In addition, composite slabs have the function of formwork. The precast part of the composite slab can serve as the bottom formwork of cast-in-place concrete on the construction site, reducing the demand for traditional wooden or steel formworks. Therefore, while ensuring the good integrity and bearing capacity of the building structure, the construction efficiency is greatly improved.

[0003] As for the composite slabs used in the floor slabs of buildings, during the installation and construction of the composite slabs, the composite slabs need to be hoisted and placed on the crossbeams of the building concrete frame by means of hoists, in order to provide effective support for the subsequent on-site pouring of cast-in-place concrete based on the composite slabs, and at the same time to ensure that the composite slabs are placed horizontally so that the thickness of the cast-in-place concrete layer is uniform. Therefore, before hoisting and installing the composite slabs, it is necessary to pre-assemble support frames in the building room to support the composite slabs. The existing composite slab support frames are basically composed of support beams and support columns. Obviously, the support beams are used to horizontally support the composite slabs, and the support columns are used to fix the support beams, and most of the support columns are height-adjustable. Although the existing support frames basically meet the installation and construction of the composite slabs, they still have the following disadvantages.

[0004] 1) If the room sizes of the building are different, it is necessary to select a support beam of appropriate length, or it is necessary to splice and lengthen multiple shorter support beams, and the applicability of the support beam is not high.

[0005] 2) The support frame is generally composed of multiple groups of support beams, and each group of support beams is supported by multiple support columns. After assembly, it is necessary to ensure that the heights of all support beams are basically the same, so as to provide effective support for the composite board. When installing composite boards in rooms with specific room sizes, it is necessary to adjust the support beams to the corresponding heights. In this case, all support columns must be adjusted one by one, which requires a large amount of adjustment and has a low adjustment efficiency. In addition, after adjusting each support column one by one, it is necessary to ensure that the support heights of each support column are basically the same, which increases the difficulty of adjustment.

[0040] like Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, a reference beam 3 is horizontally installed at the top of the support seat 23, and the reference beam 3 includes a center beam 31 fixed to the top of the support seat 23 by bolts and two support beams 32 horizontally relatively slidably installed on the center beam 31; the two support beams 32 are staggered in a horizontal direction perpendicular to their sliding direction, and the top surfaces of the two support beams 32 are jointly used as support surfaces for supporting the composite board, and the sliding groove on the support beam 32 that cooperates with the center beam 31 is open at one end and closed at the other end, and the reference beam 3 constitutes a group of assembly modules. When not in use, the two support beams 32 can be stacked and retracted, and when in use, the two support beams 32 can be pulled out relatively far apart, so that the total length of the two support beams 32 after being pulled out is adapted to the width of the building room; In order to enable the two support beams 32 to be relatively locked, a locking screw 321 is threadedly installed on the closed end of the support beam 32, and a crimping lock head 3211 is welded on the end of the locking screw 321. The crimping lock head 3211 is a cylindrical plug structure with a pressure plate. In order to increase the resistance, the crimping lock head 3211 is wrapped with a rubber layer; a long hole 322 extending along the length direction of the support beam 32 is opened on the side wall of the support beam 32 facing the other support beam 32; the locking screw 321 is locked in the long hole 322 of the other support beam 32 by the crimping lock head 3211, and by twisting the locking screw 321, the crimping lock head 3211 is inserted into the long hole 322 and pressed against the side wall of the support beam 32, thereby achieving locking.

[0041] like Figure 4 , Fig. 9 and Fig.10As shown, the two support beams 32 are detachably mounted with auxiliary support columns 4 that support the reference beam 3 together with the main adjustment column 2. The auxiliary support column 4 includes a column guide tube 41, a telescopic column 42 vertically slidably mounted in the column guide tube 41, and a top block 43 welded to the top of the telescopic column 42; the telescopic column 42 is locked to the column guide tube 41 by a plurality of bolts, and an extension hole is provided on the column guide tube 41 to avoid the bolts. When the telescopic column 42 needs to be telescopically adjusted relative to the column guide tube 41, the bolts can be loosened. The top block 43 is provided with a plug-in portion 431, and the top block 43 is plugged and matched in the slide groove at the open end of the support beam 32 through the plug-in portion 431, and the upper end surface of the top block 43 is flush with the upper end surface of the support beam 32; the telescopic column 42 is also equipped with a latch assembly 44 that locks the top block 43 on the support beam 32; the telescopic column 42 is a round tube structure, and a waist-shaped hole 421 is horizontally opened on the telescopic column 42; the latch assembly 44 includes an inner end block 441 welded in the telescopic column 42, and a cylindrical The plug pin 443 is located above the inner end block 441, and a No. 1 compression spring 442 is welded between the plug pin 443 and the inner end block 441. A U-shaped pull rod 444 is welded on the plug pin 443 and its two ends pass through the waist-shaped hole 421; a vertical avoidance hole 432 is opened on the top block 43 for the plug pin 443 to pass through, and a positioning hole 323 is opened on the support beam 32 for the plug pin 443 to be vertically inserted. When the plug pin 443 is inserted into the positioning hole 323, the top block 43 is locked on the support beam 32.

[0042] like Figure 4 , Figure 5 , Fig. 9 and Fig.11As shown, in order to improve the correlation between the two auxiliary support columns 4 and the main adjustment column 2, and thus improve the overall support strength and stability, the reference support frame 1 also includes two double-headed telescopic rods 5 horizontally symmetrically connected between the main adjustment column 2 and the two auxiliary support columns 4; a socket 212 is horizontally penetrated by the internal threaded tube 21 and the inner guide sleeve 211; a double-ear sleeve 411 for inserting the telescopic ends of the two double-headed telescopic rods 5 on the same side is welded on the column guide tube 41; the telescopic ends on both sides of the double-headed telescopic rod 5 are horizontally inserted into the two double-ear sleeves 411 one by one, and an insertion rod 51 inserted into the socket 212 is welded in the center of the non-telescopic part of the double-headed telescopic rod 5. Under the guidance of the two double earmuffs 411, and the insertion rod 51 is inserted into the insertion hole 212, the non-telescopic part of the double-head telescopic rod 5 is relatively fixed on the internal threaded tube 21, and the two auxiliary support columns 4 and the main adjustment column 2 are horizontally connected in series to form a more stable and structurally enhanced support whole; it should be noted that when the double-head telescopic rod 5 is inserted into the double earmuffs 411, the bottom end of the column guide tube 41 is flush with the bottom end of the internal threaded tube 21, and can be placed on the ground at the same time. In addition, in order to improve the stability of the support with the ground, support feet can be installed on the column guide tube 41 and the internal threaded tube 21 to expand the support surface.

[0043] In the reference support frame 1, the main adjustment column 2 serves as a support adjustment module for adjusting the overall support height of the reference support frame 1, the two secondary support columns 4 serve as auxiliary support modules that cooperate with the main adjustment column 2 to form a common support, and the reference beam 3 serves as a support end face module for composite plate support. The modules are independent of each other and all adopt a detachable structure, which is easy to transport and carry before assembly and can be quickly assembled when used.

[0044] During specific assembly, first fix the support seat 23 on the central beam 31 by bolts to complete the assembly between the reference beam 3 and the main adjustment column 2; then, dock and install the two auxiliary support columns 4 on the two support beams 32 in turn; when docking, first pull the pull rod 444 downward to make the plug pin 443 shrink into the telescopic column 42, and then make the plug pin 443 avoid the support beam 32, and then plug the top block 43 into the slide groove of the support beam 32, move it to the position where the avoidance hole 432 is aligned with the positioning hole 323, release the pull rod 444, and the plug pin 443 is engaged with the elastic force of the No. 1 compression spring 442 The top block 43 is automatically inserted into the positioning hole 323, so that the top block 43 is locked in the support beam 32, thereby completing the rapid assembly between the auxiliary support column 4 and the support beam 32; after completing the docking assembly of the two auxiliary support columns 4 in turn, the two support beams 32 are slid and pulled apart in the opposite direction, so that the overall support length formed by the two support beams 32 is adapted to the width of the building room, and then the relative locking between the two support beams 32 is completed by the locking screw 321; then, the bolts between the telescopic columns 42 and the column guide tube 41 in the two auxiliary support columns 4 are loosened, so that the column guide tube 41 naturally stands on the ground; Then, the two double-headed telescopic rods 5 are inserted into the sockets 212 through the insertion rods 51, and the two telescopic ends of the double-headed telescopic rods 5 are correspondingly inserted into the double ear sleeves 411 in the two auxiliary supporting columns 4, and the two double-headed telescopic rods 5 are horizontally inserted and docked, so that the two column guide tubes 41 and the internal threaded tube 21 are relatively fixed; then, the supporting height of the reference beam 3 is adjusted by the main adjustment column 2, and the adjusting column 22 is manually rotated The wheel 223 makes the adjustment column 22 rise as a whole relative to the internal threaded tube 21, and then the reference beam 3 is driven to rise synchronously through the support seat 23, so that the reference beam 3 rises to the corresponding support When the composite plate is placed at the height of the reference beam 3, the composite plate can be overlapped on the crossbeam of the concrete frame at the same time. During the rising adjustment process, on the one hand, under the series connection of the double-headed telescopic rod 5, the positions of the column guide tube 41 and the internal threaded tube 21 are relatively fixed. On the other hand, the support beam 32 drives the telescopic column 42 to rise synchronously through the top block 43, so that during the adjustment of the main adjustment column 2, the support heights of the two auxiliary support columns 4 are synchronously adjusted. After the height adjustment is completed, the bolts between the telescopic column 42 and the column guide tube 41 in the two auxiliary support columns 4 are tightened in turn. According to the above assembly adjustment process, the assembly adjustment of the two reference support frames 1 is completed in turn, and the support heights of the two reference support frames 1 are made equal.

[0045] like Figure 1 , Fig.12 and Fig.13As shown, the transition beam 6 includes a horizontally arranged guide beam 61 and two sliding beams 62 installed horizontally and relatively slidingly on the guide beam 61; the sliding beam 62 includes two symmetrically arranged main beam parts 621 and a bridging part 622 welded between the ends of the same side of the two main beam parts 621, and the guide beam 61 is slidably installed between the two main beam parts 621; a base 611 is welded in the center of the bottom of the guide beam 61, and a telescopic pull rod 63 is hinged between the base 611 and the bottom ends of the bridging parts 622 of the two sliding beams 62. The two telescopic pull rods 63 are connected so that the two sliding beams 62 and the guide beam 61 form a module as a whole. At the same time, the telescopic pull rod 63 enhances the overall supporting strength of the transition beam 6. When not in use, the transition beam 6 can be folded up for easy transportation and handling. When in use, the transition beam 6 can be synchronously unfolded with the unfolding amplitude of the reference beam 3.

[0046] like Figure 1 , Figure 5 , Fig.10 , Fig.12 and Fig.13 As shown, in the reference support frame 1 and the adjacent transition beam 6, the two sliding beams 62 are matched with the two auxiliary support columns 4 in a one-to-one manner, and a series beam 7 is detachably installed between the bridging portion 622 of the sliding beam 62 and the top block 43 in the corresponding auxiliary support column 4, and a series beam 7 is detachably installed between the support seat 23 and the base 611; in two adjacent transition beams 6, a series beam 7 is detachably installed between the two bases 611, and a series beam 7 is detachably installed between the bridging portions 622 of two sliding beams 62 in relative positions.

[0047] like Figure 1 and Fig.14As shown, the serial beam 7 includes a main beam tube 71 and a locking assembly 72 installed in the main beam tube 71; when the main beam tube 71 is inserted between the transition beam 6 and the reference support frame 1 or between two adjacent transition beams 6, the two plug-in ends of the main beam tube 71 are locked with the inserted end by the locking assembly 72. The main beam tube 71 is square, and square plug connectors 711 are centrally arranged at both ends of the main beam tube 71. The plug connector 711 has a step surface relative to the end of the main beam tube 71, and the step surface can be used as a positioning surface for the insertion depth. The support seat 23, the top block 43, the base 611 and the bridge portion 622 of the sliding beam 62 are all horizontally penetrated with square holes that cooperate with the plug connector 711; the locking assembly 72 includes a U-shaped gripping rod 721, and the two ends of the gripping rod 721 slide into the tube of the main beam tube 71, and an inner threading strip 723 is arranged along the tube of the main beam tube 71, and the inner threading strip 723 is welded to the two ends of the gripping rod 721. During assembly, the welding between the grip rod 721 and the inner strip 723 can be achieved through the window opened on the main beam tube 71; two No. 2 compression springs 722 are sleeved on the grip rod 721, and the two ends of the No. 2 compression spring 722 are welded to the outer wall of the main beam tube 71 and the grip rod 721; both ends of the inner strip 723 are welded with locking pins 724 arranged perpendicularly to the axial direction of the main beam tube 71, and the two locking pins 724 pass through the two plug connectors 711 in a one-to-one manner; the support seat 23, the top block 43, the base 611 and the bridging portion 622 of the sliding beam 62 are all provided with two pin holes for inserting the locking pins 724 relative to the square hole.

[0048] Before the actual assembly, the corresponding number of transition beams 6 can be selected and assembled according to the length of the room in the building. When multiple transition beams 6 are connected and fixed between two reference support frames 1 through the series beam 7, they can be assembled by multiple people. During assembly, one of the reference support frames 1 is selected as the connection object, and multiple transition beams 6 are assembled in series in sequence, and the last assembled transition beam 6 is connected to another reference support frame 1 through the series beam 7; during assembly, the gripping rod 721 is held tightly, so that the second compression spring 722 is compressed, and the locking pin 724 is retracted into the plug connector 711, and then the locking pins 724 at both ends are inserted into the square hole together with the plug connector 711, and inserted until the step surface end of the main beam tube 71 is close to the side wall of the square hole port. At this time, the locking pin 724 is aligned with the pin hole at the corresponding position, and the gripping rod 721 is released. Under the elastic force of the second compression spring 722, the locking pin 724 is aligned with the inserted pin hole to complete self-locking, thereby completing the serial docking and locking assembly of the series beam 7. When multiple transition beams 6 are sequentially connected between two reference support frames 1 through the series beam 7 as a series member, the assembly of the device of the present invention is completed, and the top support surfaces of the guide beam 61, the sliding beam 62 and the support beam 32 are flush, together forming a horizontal support surface for the placement support of the composite plate. The three series beams 7 are locked and connected between the transition beam 6 and the reference support frame 1 or between two adjacent transition beams 6, and the three series beams 7 are non-collinearly distributed, which can effectively disperse the support load and maintain the support strength.

[0049] After the assembly is completed, the composite plate construction is carried out. The composite plates can be laid flat on the top of the device support surface in sequence by a crane. When the cast-in-place concrete pouring is completed and the pouring layer is solidified, the device can be quickly disassembled one by one.

[0050] The present invention provides a quick leveling device for installing a composite plate, which is used for supporting the bottom end of the installed composite plate horizontally. The device is composed of a plurality of module components, including a reference support frame 1, a transition beam 6 and a series beam 7. The reference support frame 1 is further composed of a plurality of sub-module components, including a main adjustment column 2, a reference beam 3, a secondary support column 4 and a double-head telescopic rod 5. The module components are connected by a quick-disassembly assembly connection structure design, which can be quickly assembled on site and is also convenient for subsequent quick disassembly and transportation. The support height of the device is determined by two reference support frames 1, and a plurality of transition beams 6 are connected to the two reference support frames through the series beam 7. The assembly design between the support frames 1 makes the support end face of the transition beam 6 consistent with the support end face of the reference support frame 1 in height, and a large number of support column structures are omitted below the transition beam 6, which simplifies the number of components of the device and increases the construction activity space in the room at the same time; in addition, the reference support frame 1 only uses the main adjustment column 2 for rapid height adjustment, that is, only two height adjustments need to be completed in a single support system, which solves the problem of requiring large-scale synchronous adjustment of the height of the support columns in the existing support frames, can achieve rapid height adjustment and leveling, and better ensure the overall level of the support end face. The reference beam 3 and the transition beam 6 in the reference support frame 1 both adopt a deployable and foldable structure, which is convenient for folding and transportation, and can also be quickly unfolded and extended according to the width of the room during assembly, enhancing the flexibility and applicability of the device.
