Description

Technical Field

[0001] The utility model belongs to the technical field of building construction and relates to a side support system based on a beam template. Background Art

[0002] The steel truss floor deck is a composite structural system formed by processing the main load-bearing steel bars in the floor slab into steel trusses using special equipment in the factory, and then welding the steel trusses and galvanized steel plates into one. During the construction stage of the structural floor slab, the steel truss floor deck replaces the construction formwork with galvanized steel plates, and the truss structure formed by welding the steel bars in the structure bears the dead weight of the floor slab concrete and the construction load together; after pouring the concrete, the steel truss concrete floor slab is formed to bear the use load during the use stage. The steel truss floor deck is economical, convenient, safe and reliable. It is currently widely used in multi-story factories, multi-story, high-rise, high-rise steel structure buildings, various irregular floors, various prefabricated panels, high-speed railways and other structural and construction fields.

[0003] In the actual construction process of steel truss floor decking, the following problems often exist:

[0004] 1. During the pouring process, the steel truss floor decking leaks seriously, especially at the intersection of the steel truss floor decking and the beam-column. Usually, double-sided tape is pasted on the uneven lower side of the truss floor decking to fix it on the side formwork of the beam formwork, but the iron sheet of the floor decking fails to be tightly spliced ​​with the beam formwork, and there is a gap in the inner corner.

[0005] 2. During the construction process, in order to ensure the quality of the finished floor slab and avoid safety accidents, the existing steel truss floor decking construction often still uses traditional full-floor scaffolding support, sets up traditional formwork within 60cm of the slab extension, and then sticks double-sided tape on the outer edge of the uneven bottom of the truss floor decking to simply fix the truss floor decking on the formwork. This construction method makes it impossible to give full play to the integrity and support-free advantages of the steel truss floor decking, and the cost of measures is no different from that of traditional cast-in-place concrete slabs. As a prefabricated structure, the efficiency of installation and construction of the steel truss floor decking is not fully utilized, but it takes longer time than cast-in-place slabs.

[0006] In order to solve the above problems, it is necessary to improve the existing support form to solve the problems of serious slurry leakage, cumbersome support and low construction efficiency in traditional support structures. Utility Model Content

[0007] In view of this, the utility model provides a side support system based on the beam formwork. Relying on the beam formwork, a side support system is set up to replace the traditional full-floor scaffolding, which provides effective end support for the laying of steel truss floor decking, reduces the engineering workload and construction cost of support operations, eliminates the gap between the steel truss floor decking and the beam, and effectively solves the problem of leakage caused by the gap between the steel truss floor decking and the beam.

[0009] Furthermore, the support plate also includes a long web, and the support plate is a rectangular structure. The support plate has a long side and a short side. The long web is vertically arranged at the position of the long side of the support plate and is located on the bottom surface of the support plate. The support plate is arranged in a manner that the long web is in contact with the outer wall surface of the beam formwork.

[0010] Furthermore, the support plate also includes a short web, which is vertically arranged at the position of the short side of the support plate and located on the bottom surface of the support plate; there are two short webs, and the two short webs are respectively arranged at the positions of the two short sides of the support plate, and the two ends of the long web in the length direction are respectively connected to the two short webs.

[0011] Furthermore, two short webs at adjacent positions corresponding to any two adjacent support plates are attached to each other and detachably connected.

[0012] Furthermore, the long sides corresponding to the long webs extend outwardly along the width direction of the support plate to form overlapping flanges; the bottom surface of the overlapping flanges overlaps the top surface of the side formwork portion of the beam formwork.

[0013] Furthermore, the outer end surface of the lap flange is flush with the inner wall surface of the beam template. The outer end surface here refers to the end surface of the lap flange facing the beam template, and the inner wall surface of the beam template refers to the inner wall surface of the side template corresponding to the side of the beam overlapped with the lap flange (the side facing the concrete pouring cavity).

[0014] Furthermore, it also includes an adjusting rod and an outer rod. The bottom surface of any support plate is fixedly provided with an adjusting rod, the outer rod is vertically arranged, and an adjusting channel is arranged along the central axis of the outer rod. The entrance of the adjusting channel is located on the top surface of the outer rod, and the adjusting rod is inserted and installed in the adjusting channel in a manner that it can be moved along the adjusting channel in a limited manner.

[0015] Furthermore, it also includes an adjusting disc, which is sleeved on the adjusting rod, and the bottom surface of the adjusting disc is against the entrance of the adjusting channel, so that the adjusting rod is limited in the axial direction; the adjusting rod is connected to the adjusting disc by threaded cooperation, and the adjusting disc can be driven to rotate, so that the adjusting rod is driven to move axially.

[0016] Beneficial effects of the utility model:

[0017] The utility model provides a side support system based on beam formwork. With the beam formwork as support, the side support system is set up to replace the traditional full-floor scaffolding, reducing the engineering workload and construction cost of the support operation.

[0029] As shown in the figure, this embodiment will further illustrate the utility model in combination with a cast-in-place floor construction method based on a steel truss floor deck.

[0030] The aforementioned cast-in-place floor construction method based on steel truss floor deck specifically includes the following steps:

[0031] S1, support the beam formwork 2, and set up the side support system 1; before step S1, preparation work is still required. Before construction, the initial position of the support system should be determined according to the axis and the frame plan layout according to the construction drawing, and the frame arrangement and the module of the steel truss floor slab support platform should be verified and arranged. Then, according to the design drawings, the specific position and elevation of the floor should be determined, and the main control line should be placed using the theodolite, and then the total station and ink fountain should be used for measurement and layout; the wall column steel bars at the construction site should be tied according to the design drawings, and the wall column steel bars should be concealed after the tying is completed. After the acceptance is qualified, the wall column should be closed; after the preparation is completed, the beam formwork 2 and the supporting structure at the bottom of the beam should be erected according to the design drawings, and it should be ensured that the beam formwork 2 is erected flat and stable.

[0032] In this embodiment, the side support system 1 includes a plurality of support plates 3, which are arranged in a lockable manner to move in the vertical direction; the plurality of support plates 3 are arranged on the outer side of the beam formwork 2 along the circumference of the beam formwork 2, and any two adjacent support plates 3 fit each other. As shown in the figure, the support plates 3 are arranged along the periphery of the beam formwork 2, that is, the plurality of support plates 3 are installed and arranged along the supporting structure of the beam formwork 2, so that support plates 3 are arranged on both sides of the beam formwork 2 in the area where the steel truss floor decking needs to be laid, and the plurality of support plates 3 are arranged as shown in the figure, forming a reliable support platform structure on the outer side of the beam formwork 2, which provides an effective support foundation for the laying of the steel truss floor decking, and also provides a working platform for the workers during construction. The support plate 3 in this embodiment also includes a long web 4 and a short web 5. As shown in the figure, the support plate 3 is a rectangular structure. The support plate 3 has two long sides and two short sides. The long web 4 is vertically arranged at the position of the long side of the support plate 3 and is located on the bottom surface of the support plate 3; the short web 5 is vertically arranged at the position of the short side of the support plate 3 and is located on the bottom surface of the support plate 3; that is, the long web 4 is arranged along the long side, and the short web 5 is arranged along the short side. When the support plate 3 is installed, the support plate 3 is arranged in a way that the long web 4 is in contact with the outer wall surface of the beam formwork 2. The side support system 1 in this embodiment also includes an adjusting rod 6, an outer rod 8 and an adjusting disc 7. The bottom surface of each support plate 3 is fixedly provided with an adjusting rod 6, and the outer rod 8 is also provided one-to-one with the adjusting rod 6; the outer rod 8 is vertically arranged, and the outer rod 8 is provided with an adjusting channel along the central axis, and the entrance of the adjusting channel is located on the top surface of the outer rod 8, the adjusting rod 6 is installed in the adjusting channel in a plug-in manner, the adjusting disc is sleeved on the adjusting rod 6, and the bottom surface of the adjusting disc 7 is against the entrance of the adjusting channel, so that the adjusting rod 6 is limited in the axial direction; as shown in the figure, the adjusting rod 6 is provided with an external thread, and the adjusting disc 7 is provided with a threaded through hole, the adjusting rod 6 is connected to the adjusting disc by threaded matching, the adjusting disc can be driven to rotate, so that the adjusting rod 6 is driven to move axially, and the adjusting disc 7 drives the adjusting rod 6 to move up and down through the thread, thereby realizing the function of moving the support plate 3 in the vertical direction. In this embodiment, when erecting the side support system 1, the outer rod 8 is first erected, and the diagonal rod is pulled according to the requirements of the construction plan, and the support plates 3 are plugged and installed on the outer rod 8 one by one through the adjustment rod 6 according to the modules arranged before construction, and are realized by adjusting the disc buckle 7. When the outer rod 8 is erected, it can also be connected to the supporting structure of the beam template 2 to ensure the stability of the side support system 1 after the completion of the construction.

[0033] S2, tie the beam reinforcement and reinforce the side formwork of the beam formwork 2; tie the beam reinforcement according to the design, set the beam side wall reinforcement protective layer pad, check the beam reinforcement to ensure the correct position and firm fixation. After the beam reinforcement is tied, close the side formwork and reinforce it according to the beam formwork 2 reinforcement construction plan. How to reinforce the beam formwork 2 is a conventional technical means in this technical field and will not be elaborated here.

[0034] S3, adjust the height of the side support system 1; in this embodiment, the long side corresponding to the long web 4 extends outward along the width direction of the support plate 3 to form an overlap flange 9; the short web 5 is provided with two, and the two short webs 5 are respectively provided at the positions of the two short sides of the support plate 3, and the two ends of the length direction of the long web 4 are respectively connected to the two short webs 5; the two short webs 5 at the adjacent positions corresponding to any two adjacent support plates 3 are arranged to fit each other. In step S3, adjusting the height of the side support system 1 is to adjust the height of the support plate 3 until the bottom surface of the overlap flange 9 overlaps the top surface of the side mold part of the beam template 2. As shown in the figure, in this embodiment, the adjacent support plates 3 are mutually fitted and connected by the two short webs 5 at the corresponding adjacent positions. For example, when the current support plate 3 is connected to the adjacent right support plate 3, the short web 5 on the right side of the current support plate 3 fits each other with the short web 5 on the left side of the adjacent right support plate 3, and the two can be detachably connected by means such as bolt connection to ensure the overall stability of the side support system 1. When setting up the side support system, if you encounter a beam with a corner structure as shown in the figure, the support plate 3 at the corner position needs to be provided with an overlap flange 9 not only at the position of the long side, but also at the position of the short side that fits the corner, to ensure that after the side support system 1 is set up, the top surface of the side form of all beam formworks 2 is overlapped with the support plate 3. After the overlap is completed, the outer wall surface of the overlap flange 9 is flush with the inner wall surface of the side form of the beam formwork 2. This arrangement makes the floor slab and the beam column more integrated after the concrete is poured, and there is no gap. It also prevents leakage during the concrete pouring process, effectively improving the construction quality.

[0035] S4, correcting the male buckles and female buckles of the steel truss floor deck to be laid before installation by using the correction and resetting device;

[0036] S5, laying steel truss floor decks, any steel truss floor deck is connected in a manner that its own male buckle or female buckle is corresponding to the female buckle or male buckle of the adjacent steel truss floor deck; after the buckling is completed, the male buckle and female buckle that are buckled with each other are corrected and reset by a correction and reset device so that the male buckle and female buckle are in contact with each other;

[0037] The correction and resetting device in this embodiment includes a correction head 10, a resetting head 11 and a holding handle 12. The correction head 10 and the resetting head 11 are installed at both ends of the holding handle 12. The longitudinal section of the correction head 10 is a semi-teardrop-shaped structure, and the longitudinal section of the resetting head 11 is a teardrop-shaped structure. The longitudinal section refers to the surface formed by cutting along the vertical direction shown in the accompanying drawings. The correction head 10 is used to correct the male and female buckles of the steel truss floor deck before installation in step S4, and the resetting head 11 is used to correct and reset the male and female buckles that are interlocked in step S5. As shown in the figure, the correction head 10 is a semi-teardrop-shaped structure, which has a horizontal plane. The function of the correction head 10 is to correct the buckle edge (i.e., male and female buckles) of the floor deck body before laying. The buckle edge of the floor deck body is very easy to cause deformation during transportation, hoisting, etc., which affects normal installation. Using the correction head 10 to correct it before installation can facilitate the construction. When in use, the correction head 10 is placed in a horizontal plane and pressed against one end of the male and female buckles in the manner of being attached to the floor deck body. The worker then holds the gripping handle 12 and slides it to the other side along the opening direction of the buckle edge (i.e. the direction of the buckle edge) to correct the deformed buckle edge. When resetting the buckle edge after paving, it is necessary to make the male buckle and the female buckle fit as closely as possible. Therefore, the reset head 11 is designed as a complete teardrop-shaped structure. The tip angle of the teardrop-shaped reset head 11 is larger, and the semi-teardrop-shaped correction head 10 only needs to correct the buckle edge so that it can be normally buckled and connected. Therefore, the semi-teardrop-shaped correction head 10 is selected to ensure the effect while simplifying the structure. After the steel truss floor slab is installed, the reset head 11 is inserted into the groove at one end of the buckle edge of the floor deck body. When the reset head 11 is tightly attached to the buckle edge and slides to the other end, the buckle edges of the two floor deck bodies can be combined more tightly, which reduces or even avoids the occurrence of slurry leakage.

[0038] In this embodiment, a connecting rod 13 is also included, and the correction head 10 and the reset head 11 are both installed on the holding handle 12 through the connecting rod 13. The connecting rod 13 has a first connecting portion 15 and a second connecting portion 14. The first connecting portion 15 is connected to the end of the holding handle 12, and the second connecting portion 14 is connected to the correction head 10 or the reset head 11. The first connecting portion 15 and the second connecting portion 14 are bent in opposite directions respectively, so that the first connecting portion 15 and the second connecting portion 14 are both in an arc structure. In this embodiment, the holding handle 12 is arc-shaped, and the extension lines of the central axes of the two connecting rods 13 intersect at the arc center of the holding handle 12. Because the floor decking body is placed on the ground or fixed on the top during correction or reset work, construction workers need to bend over or look up to operate. If the connecting rod 13 and the holding handle 12 are both coaxial straight rods, the operation is more laborious. The connecting rod 13 is designed as an "S"-shaped structure as a whole. After being installed on the holding handle 12, the whole structure becomes a continuously curved serpentine structure. In addition, the extension line of the central axis of the connecting rod 13 intersects with the arc center of the holding handle 12, making the entire correction device more labor-saving when used and convenient for workers to operate.

[0039] S6, installing the reserved opening forming assembly at the set position of the steel truss floor deck, and pouring concrete;

[0040] The reserved hole forming assembly includes an inner base 17, an outer base 16 and an embedded pipe 18. The rib truss floor deck has a floor deck body 22 and a steel truss installed on the floor deck body 22. The inner base 17 is arranged on the top surface of the floor deck body 22. The top surface of the outer base 16 is provided with a plug connector 19. The plug connector 19 of the outer base 16 is detachably connected to the inner base 17 after passing through the floor deck body 22 from the lower part of the floor deck body 22. The top surface is attached to the bottom surface of the floor deck body 22, and the bottom surface of the inner base 17 is attached to the top surface of the floor deck body 22; the embedded pipe 18 is vertically installed on the top of the inner base 17; the inner base 17 has a vertical installation channel 20, the plug connector 19 and the embedded pipe 18 are respectively plugged into the two ends of the installation channel 20 in the vertical direction, and the embedded pipe 18 is provided with a through middle channel 21 along the vertical direction, and the middle channel 21 is connected to the installation channel 20. As shown in the figure, the inner base 17 and the outer base 16 are both trumpet-shaped structures, the inner base 17 is disc-shaped, and the top surface thereof is integrally formed with the plug connector 19, and the inner surface of the plug connector 19 is provided with an external thread, and the top surface of the inner base 17 is also provided with a sealing gasket, so that after fixing, the top surface of the inner base 17 is tightly attached to the bottom surface of the floor deck body 22, and there will be no leakage of mortar. The top of the inner base 17 extends radially outward to form a trumpet-shaped flange. The inner base 17 is also vertically arranged, and an installation channel 20 is opened along the axial direction. Both ends of the installation channel 20 are provided with internal threads. The plug connector 19 is threadedly connected to the bottom of the installation channel 20, and the embedded pipe 18 is installed on the top of the installation channel 20 in a threaded connection manner, and the middle channel 21 of the embedded pipe 18 is connected to the installation channel 20 and is coaxial. After the pouring is completed, the inner base 17 and the embedded pipe 18 will form the reserved holes we need in the concrete 23, which can be used as wire holes or wire openings of the embedded pipe 18. It should be noted that after the pouring is completed, the top of the embedded pipe 18 should extend outside the concrete 23, that is, the upper part as shown in the figure. This design can protect the floor slab while also protecting the subsequent threading. After the installation is completed, the inner base 17 and the outer base 16 will form a clamping structure on the floor deck body 22. Since the plug connector 19 passes through the floor deck body 22, and the diameter of the inner base 17 is larger than the plug connector 19, and the top surface of the outer base 16 is tightly attached to the floor deck body 22, it is only necessary to open a hole in the floor deck according to the size of the plug connector 19. After the inner base 17 and the outer base 16 are installed, the clamping of the two will completely block the hole, thus avoiding leakage of slurry.

[0041] S7, after pouring, the concrete is cured and the support system is removed. Before pouring, the beam and slab steel bars need to be inspected in a hidden way, and the types, specifications, quantity, and position of the longitudinal force-bearing steel bars, the connection methods, joint positions, number of joints, percentage of joint area, etc. of the steel bars, the types, specifications, quantity, and spacing of the stirrups and transverse steel bars, and the specifications, quantity, and position of the embedded parts are checked. After the hidden acceptance of the beam and slab steel bars and the reserved embedded parts is completed, when pouring the concrete casting formwork, the pouring cannot be concentrated. During the process of impacting the template casting, the vibration time should make the slurry appear on the concrete surface, without bubbles and sinking. After the concrete pouring is completed, the concrete surface is polished and then covered with plastic film for curing and watering. After the concrete reaches the required strength, the support system is removed. The support system here includes the side support system 1, the beam template 2 and its support system, and other auxiliary support and protection systems that will be set up in actual construction but not mentioned in this embodiment, etc., which can be understood by technicians in this technical field and will not be repeated here.
