Description

Adjacent type multilayer gymnasium crossing pit

Technical Field

The utility model relates to the technical field of gymnasiums, in particular to an adjacent multi-layer gymnasium arranged across pits.

Background

Ice and snow sports and various recreational activities using ice and snow, such as skating/skiing, require low temperatures to maintain the presence of ice and snow. However, in most regions, the low temperature necessary for maintaining the presence of ice and snow cannot be stably obtained from the natural environment due to climate reasons, and therefore, it is necessary to supplement the ice and snow by artificial means. Artificial ice rinks are one of the facilities that have been created to meet this need.

However, the adjacent gym with the artificial ice rink inside has great difficulty in building. Because the artificial ice field needs to repeatedly make ice and melt ice (when the artificial ice field is not used, the artificial ice field needs to be heated to melt ice to avoid frost damage to a concrete foundation), the artificial ice field needs to have good drainage capacity and avoid water generated by melting ice from influencing other places. The current artificial ice rink is generally arranged on the ground (namely, a floor where people cannot live is arranged below the ice rink, so that water is prevented from leaking to the lower part), and is lower than the peripheral area (so that water is prevented from flowing outside), so that columns cannot be arranged in the range of the ice rink, and the use of the ice rink is prevented from being influenced. Meanwhile, due to the existence of the original building, the use of a plurality of construction instruments including a tower crane is greatly limited during construction. In addition to this, due to the nature of the game itself, the ice rink needs to be modified accordingly. For example, in the ice hockey game, due to the default rule of putting a shelf and the extremely high flying speed of the ice hockey, if the ice hockey flies to the auditorium, serious injury is caused to the unprotected audience. The ice rink must therefore be significantly below the perimeter area in order to avoid players from compromising the audience and reducing the likelihood of ice hockey flying to the auditorium.

In addition, gymnasiums with depressed areas also include various swimming/diving gymnasiums with pools several meters deep.

The applicant has found that the structure and the truss assembly of such a contiguous multi-storey stadium arranged across the pit are severely limited in construction. If the truss of the gymnasium is built in a mode of integrally lifting in place after ground assembly, the ground bearing capacity is insufficient on one hand, and the ground assembly jig frame cannot be installed on the other hand due to the obvious height difference between the sunken area and the periphery; if the truss is installed in a high-altitude sliding mode, the roof of the extended gymnasium is damaged in the sliding process because the extended gymnasium is adjacent to the original building; if the truss is built in a high-altitude in-situ assembly mode, a series of hoisting equipment including a tower crane is severely limited in use, and the unloading work after the truss is assembled is very difficult.

Detailed Description

1-2, an adjacent multi-story gym, arranged across a pit, for building a new multi-story gym adjacent to an existing building 8, the gym having a depressed area 1 in a first floor of the floor, the depressed area 1 comprising a swimming pool or an artificial ice rink; the outer wall of the original building 8 and the wall surface adjacent to the multi-layer gym are marked as leaning surfaces, the horizontal line parallel to the leaning surfaces is marked as a wall-following line, and the line vertical to the leaning surfaces is marked as a wall-hanging line; the gymnasium is divided into a plurality of construction sections which are arch-shaped and span the sunken area 1 along the wall line, and the construction sections are tightly spliced together;

each construction section comprises a plurality of layers of floors aligned up and down, a plane truss arranged between the adjacent floors and a main column 2 for supporting the floor at the bottommost layer; the floor includes many perpendicular to leaning on the face and along following the girder 3 that the wall line interval set up, and the girder 3 of each floor aligns from top to bottom, and the girder 3 of adjacent two-layer floor links as an organic whole and forms the plane truss through straight web member and oblique web member, and 3 both ends of girder of below erect on the ground outside sunken area 1 through principal post 2 respectively.

The gymnasium is built in a high-altitude in-situ assembly mode and comprises the following steps:

the method comprises the following steps: building a main column 2;

step two: dividing the gymnasium into a plurality of construction sections which are constructed sequentially along a wall line, and recording the direction from the initial construction section to the final construction section as the construction direction; starting from a construction section at one end along a wall line, building temporary support columns 6 in the construction section, wherein the temporary support columns 6 are positioned in the sunken area 1, are used for supporting a main beam 3 to be installed and are arranged at intervals along the length direction of the main beam 3 to be installed; two rows of temporary support columns 6 positioned at the forefront in the construction direction among the temporary support columns 6 in the newly constructed construction section are marked as edge supporting columns;

in the edge supporting columns, the temporary supporting columns 6 in the first row which are positioned at the forefront in the construction direction are used in the next construction section, so that the edge supporting columns cannot be removed, the temporary supporting columns 6 in the second row which are positioned at the forefront in the construction direction are reserved, so that the dislocation of the joint of the two construction sections in the unloading process is avoided, and the condition that the joint of the construction sections cannot be smoothly spliced due to the downward deflection is found after stress analysis in the unloading process because the middle of the construction sections which are the same as the arch door is downwarped, and if the temporary supporting columns 6 in the second row are also removed;

step three: building each floor positioned in the current construction subsection layer by layer;

step four: and D, detaching all temporary support columns 6 except the side supporting columns in the step II, transferring to the next construction section, completing construction of each floor of the next construction section, and circularly reciprocating to complete construction of floors of all construction sections.

Step five: the swinging decoration column 51 is built on the floor slab at the top layer and the foundation at the vertical wall position passing through the left edge and the right edge of the leaning surface, the roof steel grating 5 is built on the swinging decoration column 51 to wrap the whole multilayer gymnasium, and the roof steel grating 5 is seamlessly connected with the roof of the original building 8. Since the newly constructed gym functions as a hockey game independent of the original building 8 and cannot be exactly the same in size as the original building 8, which causes serious incongruity in appearance, we choose to cover the newly constructed gym with a cover so that the two can smoothly transit in appearance and the appearance is a continuous and integrated roof. This cover has a small self-weight and is thus supported by the rocking ornament post 51. The swinging decoration post 51 is built on the foundation with the vertical wall position, so that two sides of the extended gymnasium can be aligned with two sides of the original building 8.

And step three and step four, building each floor by adopting the same method, wherein the step three is as follows:

step 3.1: the main beams 3 are installed on the temporary support columns 6 and the main columns 2,

step 3.2: the purlins 4 are connected with the main beams 3 to form a grid structure;

step 3.3: laying a floor bearing plate on the latticed structure and reserving avoidance openings on the floor bearing plate to enable the interfaces of the straight web members and the inclined web members to extend above the floor bearing plate;

step 3.4: the construction of the plane truss of the current floor is completed by taking the girder 3 of the current floor as a lower chord and the girder 3 of the upper floor as an upper chord and pressing the sequence of the lower chord, the straight web member, the upper chord member and the inclined web member;

the installation sequence is designed by considering the transmission of force, the straight web members are members for transmitting the self weight of the upper floor to the lower floor, so the straight web members are required to be immediately constructed after the lower chords are installed, then the upper chords are immediately installed, the upper chords are ensured to be effectively pressed to the straight web members, and then the inclined web members are installed;

step 3.5: and (3) circularly performing the steps 3.2-3.4 above the plane truss of the current floor to complete the construction of each floor of the current construction subsection.

The planar truss is divided into a plurality of sections in sequence along a vertical wall line from one end far away from the leaning surface for hoisting, the number of the sections of each planar truss is the same, and two ends of the sections with the same serial number in each planar truss section are aligned end to end; among three ground areas outside the gymnasium, the area opposite to the leaning surface is taken as a truck-mounted area 92, the other two areas are taken as tower crane areas 91, the section close to the truck-mounted area 92 in each plane truss section is taken as a truck-mounted section, and the other sections are taken as tower crane sections; and the truck crane section is hoisted through a truck crane arranged in a truck crane area 92, and the tower crane section is hoisted through a tower crane arranged in a tower crane area 91.

The ideal condition of truss member hoisting is that the hoisting is carried out by using a truck crane, and the hoisting capacity of the truck crane is far stronger than that of a tower crane, so that heavier members can be hoisted at one time. However, due to the existence of the artificial ice field lower than the surrounding area, the truck crane cannot be driven into the artificial ice field, so that only the components at the edge of the stadium can be hoisted by the truck crane. Most of the components still need to be hoisted by a tower crane. But because of the existence of the original building 8, the tower crane has great limitation when in use. The original building 8 is a gymnasium with a large amount of glass used in the shell, decoration is already finished, and if the lifting rope and the lifting hook of the tower crane collide with the original building 8, the damage can be caused to the original building 8. Therefore, the boom of the tower crane should not rotate greatly, and preferably should not be located above the original building 8, and preferably should be parallel to the leaning surface, so as to avoid the lifting rope and the lifting hook from hitting the original building 8 to the maximum extent.

The tower crane has two using modes, if the suspension arm of the tower crane is long enough, the tower crane segments with the same serial number can correspond to one tower crane, and when the suspension arm of the tower crane is in a position parallel to a downwall line, the downward projection of the suspension arm is intersected with each corresponding tower crane segment. Therefore, the tower crane can be hoisted on the premise that the suspension arm is parallel to the leaning surface and does not rotate basically, a component to be hoisted can be placed in the tower crane area 91, and the component can be horizontally moved to the installation position along the direction of the wall line after being hoisted. Not only can the damage caused by the collision of the lifting rope and the lifting hook to the original building 8 be avoided, but also the lifting of the double machines is facilitated. The tower cranes corresponding to the two adjacent tower crane segments are distributed in different tower crane areas 91, because the maximum hoisting weight at the tail end of the boom of the tower crane is far smaller than the root of the boom, if the tower cranes are placed in the same tower crane area 91, the situation that the maximum hoisting weight is insufficient in the construction segment close to the tail end of the boom can be caused.

If the suspension arm of the tower crane is not long enough, the downward projection of the suspension arm parallel to the wall line is intersected with each corresponding tower crane section, each plane truss can also be divided into three sections, and each plane truss comprises two tower crane sections with the same length and a truck-mounted section with the length larger than that of each tower crane section; two tower cranes corresponding to the tower crane segments are arranged in two different tower crane areas 91. In this way, the suspension arms of the two tower cranes can finish hoisting only by sweeping a sector with a small angle. The longer section of the truck crane is that the maximum hoisting weight of the truck crane is larger, so that the section of the truck crane is lengthened, the section of the tower crane is shorter and less, and the amplitude of rotation required by the tower crane is reduced.

The basement used as a machine room and a garage is further arranged below the sunken area 1, the main column 2 is arranged outside the range of a basement top plate, and a construction supporting system of the basement top plate is reserved to be dismantled after the construction of the gymnasium is completed. Because subside area 1 needs a large amount of refrigeration and heating equipment, and these machines can not set up in the venue, otherwise can influence the match and go on, so we put these equipment through setting up the basement again below subside area 1, but set up the basement, temporary support post 6 can press the roof of basement in the construction, transmits the dead weight of gymnasium to basement roof part, can surpass the bearing capacity of basement roof. Therefore, in the process of building the part above the ground of the gymnasium, the construction supporting system of the basement needs to be reserved until the construction of the gymnasium is completed, and then the basement can be dismantled.

The straight web members in the plane truss of each layer are aligned up and down, the straight web members at two ends of the plane truss are coaxially arranged with the main column 2, and the rest straight web members are coaxially arranged with the temporary support columns 6. Therefore, the transmission of the force in the truss is simple and efficient, and the stress analysis can be further simplified.

The main column 2 is an H-shaped stiff steel rib column, the bottom of the main column 2 is provided with a friction pendulum shock insulation support, and the friction pendulum shock insulation support is provided with a damper; girder 3 is the box girder steel, and straight web member, oblique web member and purlin 4 are H shaped steel, and the floor carrier plate is the profiled sheet that has the reinforced concrete layer of having spread to the top, and latticed structure makes up into the floor with the floor carrier plate. That is to say, the truss members with larger sizes are adopted in the application, so that the number of the truss members needing to be hoisted can be reduced as much as possible, and the workload of high-altitude splicing is reduced.

In the purlins 4, be close to the leaning surface and be provided with oblique web member between the upper and lower adjacent purlins 4, keep away from leaning surface and be provided with oblique web member between the upper and lower adjacent purlins 4. The diagonal web members of this section are primarily intended to facilitate the installation of the wall panel.

The seam crossing welding between each segmentation of girder 3 and the seam crossing between girder 3 and the oblique web member has down-warping prevention cardboard 7, prevents the seam at the vertical setting of face and the perpendicular to place of down-warping cardboard 7, and offers on the face to be used for pulling up each component in order to avoid the hanging hole of seam crossing down-warping. Under the general condition, the truss member relies on the temporarily fixed otic placode to come the temporary connection, and every set of temporarily fixed otic placode includes two parallel arrangement and through the steel sheet of a row of bolt that arranges along member length direction even as an organic whole in order to increase rigidity to avoid seam crossing stagger or downwarping, but the size of the truss member that adopts in this embodiment is very big, and the dead weight is also big, leans on the temporarily fixed otic placode to avoid downwarping completely.

Of the two truss members at the joint, the truss member installed first is referred to as the first installed member, and the truss member installed later is referred to as the second installed member. The contact surface of the anti-downwarping chuck plate 7 and the rear mounting component is larger than the contact surface of the anti-downwarping chuck plate 7 and the front mounting component. The hanging hole is opened at a position where the downwarping preventing catch plate 7 is located above the rear mount member. The attachment members are already connected to the truss and therefore have less of a requirement for the pull-up force, whereas the attachment members are not yet connected to the truss and therefore have a higher requirement for the pull-up force, where the position adjustment of the anti-downdraft catch 7 is made to more effectively pull up the attachment members.

The bottom of the anti-downwarping clamping plate 7 is provided with a position avoiding opening used for avoiding the seam so as to avoid influencing the welding of the seam.

Two anti-downwarping clamping plates 7 are oppositely arranged at each joint position so as to facilitate hoisting.

Temporary support post 6 is formed by the coincide of a plurality of tower crane standard festival, and 6 tops of temporary support post are provided with adjustable steel shotcrete, and adjustable steel shotcrete has made things convenient for the uninstallation of truss, and the tower crane standard festival has made things convenient for building and dismantling of temporary support post 6. And a base used for avoiding crushing the subsidence area 1 by the vertical rod of the standard knot of the tower crane is arranged at the bottom of the temporary support column 6.

The temporary support columns 6 are assembled and disassembled by means of a truck crane and a tower crane, wherein the truck crane can be used for a truck crane and can not be used for a tower crane. Because the construction segment of this kind of arched door formula in this application leads to all interim support columns 6 not far away from the construction segment border that has been under construction and accomplished after the construction segment is accomplished, once dismantling adjustable steel shotcrete, just can directly make down tower crane standard festival one by one directly with tower crane or mobile crane and transfer to new position simultaneously, do not need the secondary to transport. Note that in this process, the motion trail of the tower crane standard knot can be the same as a pendulum, so the tower crane standard knot is pulled by a rope along a wall line, the tower crane standard knot does not need to swing freely but slowly rotates downwards from a constructed construction section, and the tower crane standard knot at the bottommost needs to be pulled upwards simultaneously when rotating outwards so as to avoid colliding with the ground.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
