Description

TECHNICAL FIELD

[0001] The present application relates to a prefabricated pipeline and floor integrated modular assembly system and construction method. BACKGROUND

[0002] At present, the construction technology of integrated hoisting and assembly of combined vertical pipes in high-rise buildings in China has been initially formed, and has been verified to have certain feasibility, and the process principle is mainly factory prefabrication, that is, 2-3 floor height of various pipes are fixed by supports to form a stable pipe group system, and integrated hoisting operation is carried out.

[0003] In the construction process, it is found that in the past, when hoisting the vertical pipe group, a wall sleeve is generally set in advance at each layer through the floor, but this method has very high requirements for the position accuracy of each pipe group and the pipe group, otherwise, slight deviation will cause the pipe group to not pass through the sleeve, and the sleeve needs to be removed and re-buried, which is a large amount of work; if the wall sleeve is not set in advance at the floor or the pipe group is hoisted in the pipe well, the reserved hole of each layer needs to be supported and the concrete needs to be poured for plugging treatment after the pipe group is hoisted and assembled, which is also a large amount of work and has a certain influence on the construction period. Although some projects use the pipe group shared support as the plugging material of the floor reserved hole for integrated embedding, but this method needs to accurately grasp the related parameters such as the building height of each floor and the size of the reserved hole, otherwise, slight deviation will cause the position of the shared support and the size of the reserved hole to be inconsistent, affecting the stress strength and overall aesthetic coordination of the floor. At the same time, in the space-limited place, the support needs to be adjusted back and forth to ensure that it is flush with the floor, which is time-consuming and laborious to implement, and the safety of the operating personnel cannot be guaranteed.

[0054] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0055] As shown in Figures 1 to 9 The prefabricated pipeline and floor integrated assembly system 100 provided by the present application comprises:

[0056] The prefabricated floor component 110 is arranged in the pipe well reserved hole or the floor reserved hole 140, the sleeve 112 is arranged in the concrete 114 of the prefabricated floor component 110, the through-floor vertical pipe group is arranged in the sleeve 112, the first reinforcing steel 111 is arranged on both sides of the prefabricated floor component 110, the lifting lug 113 is arranged on the prefabricated floor component 110, and the first reinforcing steel 111 arranged on both sides of the prefabricated floor component 110 is connected with the second reinforcing steel 141 arranged on the side of the pipe well reserved hole or the floor reserved hole 140;

[0057] Here, each component of the prefabricated floor component can be prefabricated by a related mold in a factory;

[0058] The anti-collision protection frame 120 for the pipe joint interface installed on the upper part of the precast floor slab component includes: a square steel pipe frame 121, a first clamp 122, a double-ended bolt 125, a lifting sling 126, and a turnbuckle 127. The first clamp 122 is connected to the space enclosed by the square steel pipe frame 121 through the double-ended bolt 125. The first clamp 122 covers the interface of the vertical pipe group passing through the floor slab. The lifting sling 126 is installed on the square steel pipe frame 121 and is connected to the lifting lug 113 through the turnbuckle 127.

[0059] The combined riser bracket 130, which is installed on the upper part of the anti-collision protection frame 120 of the pipe group interface, includes: bracket fixing plate 131, common bracket 132 and second clamp 133, wherein the second clamp fixes the riser group through the floor slab to the common bracket, and the common bracket is fixed to the wall above the reserved hole of the pipe well or floor slab 200 through the bracket fixing plate.

[0060] Here, the vertical pipe assembly that passes through the floor slab fixes a single pipe to a common support by a second clamp, and the common support is fixed to the wall above the reserved hole in the pipe well or the reserved hole in the floor slab by a support fixing plate.

[0061] Specifically, the dimensions of pipe shafts or reserved holes on each floor are generally not very large. During hoisting, riser assemblies penetrating the floor slab are prone to colliding with walls, floors, or other obstacles, causing the assemblies to become misaligned. In particular, external forces at the pipe joints can affect the service life and subsequent assembly accuracy. Furthermore, if a section of the pipe assembly encounters an obstacle during hoisting and is not detected in time, continued hoisting may damage the building or the pipe assembly, and in severe cases, may even lead to a safety accident, endangering the lives of relevant personnel.

[0062] In addition, the traditional on-site enclosed concrete floor slab pouring is easily constrained by the environment, technology, construction space, tools, etc., which may lead to quality problems such as floor slab cracking and poor compaction.

[0063] like Figure 4 As shown, in one embodiment of the prefabricated pipeline and floor slab integrated modular assembly system of the present invention, the square steel pipe frame includes multiple square steel pipes, which enclose a rectangular space. Two square steel pipes are connected by angle steel 123 and single-headed bolts 124 passing through the square steel pipe and angle steel 123.

[0064] Here, the main body of the anti-collision protection frame for the pipe assembly interface is composed of four rectangular steel pipes with a cross-sectional size of 80mm×50mm. Adjacent steel pipes are assembled into a rectangular frame by special angle steel components and single-headed bolts. The size of the frame is set according to the actual size of the riser assembly.

[0065] like Figure 7 and8 As shown, in one embodiment of the prefabricated pipeline and floor slab integrated modular assembly system of the present invention, it further includes: a floor slab gap template 150 disposed in each component for the surrounding gap between the prefabricated floor slab component 110 and the reserved hole in the pipe well or the reserved hole in the floor slab 140. The floor slab gap template 150 includes: a plywood panel 151, a lifting eye bolt 152, a nut 153 and a wire rope sleeve 154. The wire rope sleeve 154 is suspended at the reserved reinforcing bar of the prefabricated floor slab component 110. The lifting eye bolt 152 is connected to the wire rope sleeve 154. The plywood panel 151 is connected to the lifting eye bolt 152 through the nut 153.

[0066] Here, the floor slab gap formwork is used to provide formwork support for pouring concrete in the surrounding gaps between the precast floor slab components and the reserved holes in the manholes or the reserved holes in the floor slab.

[0067] The precast floor slab component is slightly smaller than the reserved holes in the pipe shaft or the reserved holes in the floor slab, with a gap of about 5cm on each side. The component is filled with crisscrossing steel bars. The specifications and arrangement of the steel bars are set according to the structural strength of the building floor slab. The riser assembly that passes through the floor slab is fixed to the steel bars by the steel wire winding method. After the binding is completed, concrete is poured on the mold to precast the structure.

[0068] In one embodiment of the prefabricated pipeline and floor slab integrated modular assembly system of the present invention, the floor slab gap template 150 is a rectangular hollow structure.

[0069] Here, the floor slab gap template is a rectangular hollow structure made of 18mm thick plywood panels. The template can be suspended from the pre-reserved steel bars in the floor slab by steel wire ropes.

[0070] like Figure 6 As shown, in one embodiment of the prefabricated pipeline and floor slab integrated modular assembly system of the present invention, one end of the second reinforcing bar on the side of the reserved hole in the pipe well or the reserved hole in the floor slab 140 is inserted into the reinforcing bar sleeve 142, and the first reinforcing bar 111 is inserted into the reinforcing bar sleeve 142 and connected to the second reinforcing bar 141.

[0071] Here, the steel bar sleeve can connect and fix the first steel bar of the precast floor slab component to the second steel bar on the side of the reserved hole in the manhole or the reserved hole in the floor slab.

[0072] The reserved holes in the manhole or floor slab are slightly wider than the dimensions of the precast floor slab components. Reinforcing bars matching the positions of the precast floor slab components are reserved on both sides, and can be connected to the precast floor slab components through reinforcing bar sleeves.

[0073] like Figure 1As shown, the prefabricated pipeline and floor integrated modular assembly system embodiment of the present application further comprises: a smart weight display limiter 160 connected to the top of the combined vertical pipe support 130.

[0074] Here, the smart weight display limiter is used to monitor the weight of the hoisted prefabricated pipeline and floor integrated modular assembly system and provide overload protection during the hoisting process of the prefabricated pipeline and floor integrated modular assembly system.

[0075] The smart weight display limiter can be installed on the crane hook and is mainly used to monitor the weight of the hoisted object and provide overload protection during the hoisting process.

[0076] In the prefabricated pipeline and floor integrated modular assembly system embodiment of the present application, the three horizontal first steels at the upper, middle and lower positions of the prefabricated floor component extend 5 cm out of the surface of the prefabricated floor component.

[0077] Here, the three horizontal first steels at the upper, middle and lower positions of the prefabricated floor component extend 5 cm out of the surface of the prefabricated floor component, and the steels at the remaining positions of the prefabricated floor component are arranged inside the prefabricated floor component.

[0078] In the prefabricated pipeline and floor integrated modular assembly system embodiment of the present application, the inner side of the first hoop is provided with a rubber soft pad.

[0079] Here, the size and number of the first hoop inside the pipe group interface anti-collision protection frame are set according to the requirements of the vertical pipe group, the two sides of the hoop are connected with the protection frame through double-headed bolts, and the inner side of the first hoop is provided with a rubber soft pad.

[0080] The prefabricated pipeline and floor integrated assembly construction method of the present application is further described in detail below in combination with the drawings and specific embodiments.

[0081] Step one: according to the size of the building pipe reserved hole well or the floor reserved hole and the number and specification of the vertical pipes in the vertical pipe group, a prefabricated floor component process flow is formulated and related molds are made, and second steels connected with the first steels of the prefabricated floor component 110 are reserved on the side of the building pipe reserved hole well or the floor reserved hole;

[0082] Step two: according to the process flow, the first steel 111, lifting lug 113 and sleeve 112 in the prefabricated floor component 110 are bound and arranged in the corresponding mold, after the position is confirmed to be correct, the concrete is poured, and the prefabricated floor component 110 is maintained under the same conditions according to the design requirements, the load capacity experiment of the lifting hook is carried out after the strength meets the requirements, and the prefabricated floor component 110 is stored in batches after meeting the requirements;

[0083] Step 3: Based on the number and size of the pipes in the vertical pipe assembly that penetrates the floor slab, make the corresponding anti-collision protection frame 120 for the pipe assembly interface. The size and position of the clamps 122 inside the anti-collision protection frame 120 should correspond one-to-one with each vertical pipe in the vertical pipe assembly that penetrates the floor slab. Make the corresponding number of anti-collision protection frames for the pipe assembly interface according to the actual number of sections of the vertical pipe assembly that need to be lifted.

[0084] Step 4: When assembling the modular riser support 130 in the prefabrication site, simultaneously place the prefabricated floor slab components at the corresponding positions of each riser in the floor slab riser assembly. After the modular riser support 130 and the prefabricated floor slab components are assembled, transport them together to the hoisting site.

[0085] Step 5: After the assembled modular riser support 130 and precast floor slab components are transported to the site, install the anti-collision protection frame 120 for the pipe joints. Install the first clamp of the anti-collision protection frame 120 above the interface (clamp, flange, weld) of each riser in the floor slab. At the same time, adjust the length of the wire rope of the lifting sling according to the height of each floor (generally, the positions of each pipe joint interface in each floor are at the same horizontal height, within the range of 1.2m to 1.5m from the ground). After the wire rope of the lifting sling is adjusted, connect the lifting sling 126 on the anti-collision protection frame 120 to the lifting lug 113 on the precast floor slab component 110 through turnbuckles to complete the assembly of the modular riser support 130, the precast floor slab component, and the anti-collision protection frame for the pipe joints.

[0086] Step Six: Before lifting the assembled modular riser support 130, precast floor slab components, and anti-collision protection frame for pipe interfaces, first install an intelligent weight limiter on the crane hook, then connect the intelligent weight limiter to the top of the modular riser support 130, and then slowly lift the assembled modular riser support 130, precast floor slab components, and anti-collision protection frame for pipe interfaces. At the same time, record the total weight of the lifted objects and monitor the weight changes of the lifted objects in real time in the control room.

[0087] During hoisting, dedicated personnel should be stationed at each floor shaft or reserved floor slab opening where the pipe assembly passes through to monitor and protect the area. In particular, when precast floor slab components pass through the floor slab, the hoisting speed should be slowed down to avoid collisions between the pipe assembly / components and the walls.

[0088] like Figure 10As shown, preferably, when the intelligent weight limiter monitors that the lifting weight changes to 90% of the hoisted object weight, the intelligent weight limiter flashes yellow light, and the buzzer emits intermittent pre-warning sound; when the intelligent weight limiter monitors that the lifting weight changes to 100% of the hoisted object weight, the intelligent weight limiter flashes red light, and the buzzer emits continuous alarm sound; when the intelligent weight limiter monitors that the lifting weight changes to 105% of the hoisted object weight, the intelligent weight limiter emits continuous alarm sound and the red indicator light is always on, and simultaneously the crane contactor power supply is automatically cut off.

[0089] In the case of any of the above situations, the relevant personnel should report the hoisting situation of each floor in time and eliminate the operation risk in time to ensure the smooth progress of subsequent operation.

[0090] Step seven: after the combined vertical pipe support is hoisted into place, the combined vertical pipe support is fixed on the wall above the pipe well reserved hole or the floor reserved hole, then the precast floor member 110 is adjusted to the same horizontal height with the pipe well reserved hole or the floor reserved hole position through the flower basket bolt on the hoisting cable of the up and down adjustable pipe group interface anti-collision protection frame, the first steel bars extending from both sides of the precast floor member are connected with the second steel bars on the side of the pipe well reserved hole or the floor reserved hole through the steel sleeve and are spot welded.

[0091] Here, if the leaked transverse steel bars at both ends of the precast floor member are aligned with the reserved steel bars at the floor, the two ends are connected together through the steel sleeve, and the contact length of each end with the steel sleeve is not less than 3 cm, and the connection is firmly welded with a welding gun; if one or more steel bars cannot be completely aligned with the transverse steel bars of the precast floor member, the two steel bars connected with each other are pulled to the same radial position for alignment by using a wrench, and then the above operation is repeated.

[0092] Step eight: after the precast floor member is installed in place, the main hoist point is loosened, and then slowly withdrawn; then the floor gap formwork is hung at the corresponding position of the precast floor member (a plurality of layers can also be poured at the end), the gap panel is pre-coated with a release agent, then one end of the floor gap formwork is hung on the reserved steel bar of the precast floor member through the wire rope sleeve, the other end of the floor gap formwork is fixed on the hoisting ring bolt, and the position of the floor gap formwork is adjusted to ensure that the floor gap formwork is flush with the top surface of the lower layer, and after confirmation, the same strength grade concrete is poured on the gap panel, and the sleeve and the through-floor vertical pipe group are sealed with fireproof material;

[0093] Step nine: after the concrete on the gap panel is cured and reaches a certain strength grade, the nut is loosened to remove the floor gap formwork;

[0094] If the exposed hanger bolt screw rod at the bottom surface of the floor does not affect the appearance or use, it can not be treated, otherwise it can be cut off by a cutting machine or other tools;

[0095] Step ten: after a group of floor penetrating riser groups and corresponding multiple prefabricated floor components are installed, subsequent pipe group hoisting operations can be carried out, without waiting for the floor pouring and curing to be completed before construction; during hoisting, the above steps six to eight can be repeated for subsequent construction, and finally, after checking that there is no error, fireproof plugging is carried out in the riser.

[0096] Compared with the previous combined riser group hoisting, the device has the following advantages:

[0097] (1) The reserved hole plugging of each floor is carried out by using a prefabricated concrete floor component, the component is internally provided with a floor penetrating riser group, batch prefabrication can be carried out in a factory, professional tools and professional maintenance are not restricted by site technology and environment, the forming effect is good, and the construction period is saved;

[0098] (2) The position of the prefabricated floor component can be adjusted up and down after the pipe group is assembled, so that the floor surface can be ensured to be flush, and the practicability and operability are stronger;

[0099] (3) The interface position of the floor penetrating riser group is provided with a detachable protection frame, which can reduce the inclination of the pipe group caused by collision during hoisting, has higher safety, can be recycled, has high turnover rate, and has good economy;

[0100] (4) The concrete pouring at the gap position around the floor can be carried out through the floor gap formwork, without the need to set the formwork at the lower layer, and the operation is convenient and material saving;

[0101] (5) The weight monitoring instrument is arranged on the crane rope, which can monitor the overall weight change of the riser group and the prefabricated floor during hoisting at any time, and further ensure the operation safety during hoisting.

[0102] In addition, the device also has the advantages of simple structure, convenient operation, high production efficiency and good economy.

[0103] In the specification, each embodiment is described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts of each embodiment can be referred to each other.

Thus, if these modifications and variations of the application fall within the scope of the claims of the application and their equivalents, the application also intends to include these modifications and variations.

2. A construction method for a prefabricated pipeline and floor slab integrated modular assembly system as described in claim 1, characterized in that, The method includes: Step 1: Based on the dimensions of the reserved holes in the building pipe well or the reserved holes in the floor slab, as well as the number and specifications of the risers in the riser group passing through the floor slab, formulate the process flow for prefabricated floor slab components and make relevant molds. At the same time, reserve a second steel bar on the side of the reserved holes in the building pipe well or the reserved holes in the floor slab to connect with the first steel bar of the prefabricated floor slab component. Step 2: According to the process flow, tie and arrange the first steel bar, lifting lug and sleeve in the corresponding mold of the precast floor slab component. After confirming that the position is correct, pour concrete and cure the precast floor slab component under the same conditions as the design. After the strength reaches the standard, conduct a load-bearing capacity test on the lifting hook. After meeting the requirements, store the precast floor slab components in batches. Step 3: Based on the number and size of the pipes in the vertical pipe assembly that penetrates the floor slab, make the corresponding anti-collision protection frame for the pipe assembly interface. The size and position of the clamps in the anti-collision protection frame for the pipe assembly interface should correspond one-to-one with each vertical pipe in the vertical pipe assembly that penetrates the floor slab. Make the corresponding number of anti-collision protection frames for the pipe assembly interface according to the actual number of sections of the vertical pipe assembly that need to be lifted. Step 4: When assembling the modular riser support in the prefabrication site, simultaneously place the prefabricated floor slab components at the corresponding positions of each riser in the floor slab riser assembly. After the modular riser support and prefabricated floor slab components are assembled, transport them together to the hoisting site. Step 5: After the assembled modular riser support and precast floor slab components are transported to the site, install the anti-collision protection frame for the pipe joints. Install the first clamp of the anti-collision protection frame for the pipe joints above the joint of each riser in the floor slab assembly. At the same time, adjust the length of the wire rope of the lifting sling according to the height of each floor. After the wire rope of the lifting sling is adjusted, connect the lifting sling on the anti-collision protection frame for the pipe joints to the lifting lug on the precast floor slab component through turnbuckles to complete the assembly of the modular riser support, precast floor slab component and anti-collision protection frame for the pipe joints. Step Six: Before lifting the assembled modular riser support, precast floor slab components, and anti-collision protection frame for pipe interfaces, first install an intelligent weight limiter on the crane hook, then connect the intelligent weight limiter to the top of the modular riser support, and then slowly lift the assembled modular riser support, precast floor slab components, and anti-collision protection frame for pipe interfaces. At the same time, record the total weight of the lifted objects through the intelligent weight limiter and monitor the weight changes of the lifted objects in real time in the control room. Step 7: After the combined riser support is hoisted into place, fix the combined riser support to the wall above the reserved hole in the pipe well or the reserved hole in the floor slab. Then, adjust the position of the precast floor slab component and the reserved hole in the pipe well or the reserved hole in the floor slab to the same horizontal level by adjusting the turnbuckle on the lifting sling of the anti-collision protection frame of the pipe assembly interface. Connect the first steel bars extending from both sides of the precast floor slab component to the second steel bars on the side of the reserved hole in the pipe well or the reserved hole in the floor slab through steel bar sleeves and spot weld them. Step 8: After the precast floor slab components are installed in place, release the main crane's lifting points and then slowly withdraw it; then suspend the floor slab gap template at the corresponding position of the precast floor slab components. Apply release agent to the adhesive panel of the floor slab gap template beforehand, and then suspend one end of the floor slab gap template at the reserved reinforcement of the precast floor slab components through the wire rope loop. Fix the other end of the floor slab gap template to the lifting eye bolt. At the same time, adjust the position of the floor slab gap template to ensure that the floor slab gap template is flush with the top surface of the lower layer. After confirming that there are no errors, pour concrete of the same strength grade on the adhesive panel, and seal the sleeves and the riser assembly that penetrates the floor slab with fireproof material. Step 9: After the concrete on the plywood panel has cured and reached a certain strength level, loosen the nuts and remove the formwork for the floor slab gaps; The total weight of the suspended object is recorded by an intelligent weight limiter, and changes in the weight of the suspended object are monitored in real time in the control room, including: When the intelligent weight limiter detects that the change in the lifting weight reaches 90% of the weight of the object being lifted, the intelligent weight limiter's yellow light flashes and the buzzer emits an intermittent warning sound. When the intelligent weight limiter detects that the change in the lifting weight reaches 100% of the weight of the object being lifted, the red light on the intelligent weight limiter will flash and the buzzer will emit a continuous alarm sound. When the intelligent weight limiter detects that the change in the lifting weight reaches 105% of the weight of the lifted object, the intelligent weight limiter will emit a continuous alarm sound and the red indicator light will remain on, while automatically cutting off the power supply to the crane contactor.
