Description

Technical Field

[0001] The present invention relates to the technical field of assembled thermal insulation flooring, and in particular to an assembled thermal insulation flooring structure and a construction method. Background Art

[0002] Prefabricated insulated flooring is a building floor system that is quickly assembled on site through prefabricated components in the factory. Its core function is to improve the thermal insulation performance, sound insulation effect and construction efficiency of the building. The floor system usually includes a composite sandwich panel with an insulation layer and a floor heating layer, a grid frame composed of a main keel and a secondary keel, and an adjustment seat for adjusting the level. When assembling the floor system, first fix the adjustment seat on the base layer, then lay the main keel, and then lay the secondary keel vertically on the main keel and connect the limit by means of snaps to form a grid frame, and then adjust the level by the adjustment seat, and then install the composite sandwich panels on the grid frame in turn, and fix them by the elastic connector on the composite sandwich panels and the card slot on the grid frame, and then seal the seams with sealant to finally form a complete floor system.

[0003] The current prefabricated insulation floor structure has the following problems: First, the main purlin and secondary purlin of the existing prefabricated insulation floor are snap-fitted together, which can limit the movement in the up and down directions, but does not form an effective constraint on the front and back degrees of freedom. The secondary purlin is prone to slide longitudinally along the main purlin under load or vibration, causing the frame to shift and dislocate, causing joint cracking and collapse of the composite sandwich panel; secondly, the composite sandwich panel is fixed to the grid frame by static snap-fitting, which is prone to local collapse or displacement under concentrated load, and the sound insulation and thermal insulation performance is subsequently attenuated; at the same time, the snap-fit ​​structure is prone to loose connections due to material fatigue or stress concentration after being stepped on or impacted for a long time, resulting in a decrease in the overall rigidity of the grid frame and a significant increase in the risk of deformation.

[0004] Therefore, the connection stability between the main purlin and the secondary purlin is insufficient, and the composite sandwich panel cannot dynamically strengthen the grid frame structure when under pressure, which affects the overall structural stability and functionality of the floor. This is a technical problem that needs to be solved by technical personnel in this field. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present invention provides an assembled thermal insulation floor structure and a construction method to solve the above-mentioned technical problems.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the present invention provides the following technical solutions: an assembled thermal insulation floor structure, comprising an adjustment seat, a composite sandwich panel and a main keel, wherein a secondary keel is vertically laid on the main keel, the main keel and the secondary keel form a grid frame, the lower end of the main keel and the position corresponding to the grid frame node are clamped with an adjustment seat, and the composite sandwich panel is evenly laid on the grid frame; the assembled thermal insulation floor structure also includes a limiting mechanism; the limiting mechanism includes a plurality of circular grooves corresponding to the grid frame nodes opened at the lower end of the composite sandwich panel, a fixed disk is provided in the circular groove, and four extrusion blocks are installed on the lower end of the fixed disk along its radial sliding direction, and adjacent extrusion blocks A driving plate is arranged between them, and the driving plate cooperates with the oblique groove on the extrusion block; when the composite sandwich panel is under pressure, the distance between the driving plate and the fixed plate decreases, and the driving plate cooperates with the oblique groove to drive the four extrusion blocks to move inward synchronously to apply centripetal clamping force to the outer corners of the grid frame nodes, and the centripetal clamping force increases with the increase of the pressure on the composite sandwich panel; a limiting groove cooperating with the secondary keel is provided on the main keel, and two pairs of clamping plates are arranged in the limiting groove, and the secondary keel is a hollow cylinder with an opening at the lower end, and the inner sides of the two horizontal sections at the lower part of the secondary keel are provided with arc-shaped elastic locking plates with clamping grooves, and the main keel and the secondary keel are quickly assembled and limited by the engagement of the clamping plates and the clamping grooves.

[0007] As a preferred solution, the extrusion block has an isosceles trapezoidal structure, and the inclined ends of the extrusion block are provided with inclined grooves inclined from top to bottom toward the center of the corresponding fixed disk. Guide columns that slide in conjunction with the corresponding inclined grooves are installed at both ends of the drive plate.

[0008] As a preferred solution, a pair of compression springs are installed between the driving plate and the fixed plate, and a pair of notches are opened at the lower end of the fixed plate and at positions corresponding to the driving plate, and the compression springs are located in the corresponding notches.

[0009] As a preferred solution, a limiting column is coaxially fixedly installed on the lower end of the fixed plate, and the limiting column slides through the grid frame node to the corresponding adjustment seat.

[0010] As a preferred solution, the card plate is in an inverted L-shaped structure, and the horizontal section of the card plate is provided with an inclined surface, and the horizontal section of the card plate is partially embedded in the card slot.

[0011] As a preferred solution, the lengths of two limiting columns corresponding to the same composite sandwich panel and in a diagonal relationship are greater than the lengths of the remaining limiting columns.

[0012] The present invention also provides a method for constructing an assembled thermal insulation floor, which is completed using an assembled thermal insulation floor structure and includes the following steps: S1, cleaning and leveling the base layer, and then laying a waterproof layer.

[0013] S2. Install the adjustment seat on the waterproof layer.

[0014] S3. Connect and fix the main keel and the adjustment seat.

[0015] S4. Lay the secondary keel vertically on the main keel, and quickly fix and limit the secondary keel through the clamping plate and clamping slot.

[0016] S5. Install the composite sandwich panel, and the four extrusion blocks at the lower end of the fixed plate synchronously clamp the outer corners of the grid frame nodes, and the clamping force increases as the pressure on the composite sandwich panel increases.

[0017] One or more of the above technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the present invention achieves simultaneous three-dimensional dynamic constraint and load adaptive adjustment through the linkage design of the limit mechanism and the grid frame nodes, which not only solves the problem of easy sliding and offset of the main and auxiliary keels after assembly, but also overcomes the defect of local collapse of the composite sandwich panel under pressure. The interlocking structure of the inverted L-shaped clamping plate and the elastic locking plate forms a multi-directional rigid limit, while the extrusion block converts the vertical load into a radial clamping force, constructing a complete constraint system from initial positioning to continuous reinforcement, significantly improving the deformation resistance and durability of the overall structure.

[0018] 2. The connection node between the main keel and the auxiliary keel of the present invention adopts a collaborative locking design of an inverted L-shaped card plate and an elastic locking plate. The horizontal section of the card plate is embedded in the card slot to form front, rear, upper and lower limits. Cooperating with the left and right constraints of the limit slot, all-round fixation in the three-dimensional direction is achieved. At the same time, the deformation reset characteristics of the elastic locking plate during assembly can not only ensure smooth installation, but also maintain connection stability through continuous elastic pre-tightening force, effectively preventing longitudinal sliding under vibration or load, and fundamentally avoiding the risk of frame dislocation.

[0019] 3. The limiting mechanism of the present invention converts the deadweight and external load of the composite sandwich panel into radial clamping force on the grid frame nodes in real time through the coordinated linkage mechanism of the extrusion block and the driving plate, forming a dynamic reinforcement effect in which the greater the pressure, the tighter the clamping; the centripetal movement of the four isosceles trapezoidal extrusion blocks makes the force on the nodes evenly dispersed, avoiding stress concentration and local collapse, thereby solving the problems of joint cracking and thermal insulation performance degradation.

DETAILED DESCRIPTION

[0029] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2 As shown, an assembled thermal insulation floor structure includes an adjustment seat 10, a composite sandwich panel 11 and a main keel 12; a secondary keel 13 is vertically laid on the main keel 12, and the main keel and 12 secondary keels 13 form a grid frame. The lower end of the main keel 12 and the position corresponding to the grid frame node are all clamped with an adjustment seat 10, the composite sandwich panel 11 is evenly laid on the upper end of the grid frame and a limiting mechanism 2 is provided at the lower end thereof. The adjustment seat 10 is an existing public technology, and the specific structure is not the innovation of the present invention, so it will not be described in detail here.

[0031] like Figure 2 、 Figure 3 and Figure 4As shown, the limiting mechanism 2 includes several circular grooves corresponding to the grid frame nodes opened at the lower end of the composite sandwich panel 11; nine circular grooves are opened at the lower end of the composite sandwich panel 11 (the number of circular grooves at the lower end of the composite sandwich panel 11 is determined according to the number of corresponding grid frame node positions corresponding to the composite sandwich panel 11), and a fixed disk 20 is detachably installed in the circular groove. Four extrusion blocks 21 are radially slidably installed at the lower end of the fixed disk 20, and a driving plate 22 is provided between adjacent extrusion blocks 21, and the driving plate 22 cooperates with the inclined groove 210 opened on the extrusion block 21.

[0032] like Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the main keel 12 is provided with a limiting groove that cooperates with the secondary keel 13, and two pairs of clamping plates 3 are arranged in the limiting groove. The secondary keel 13 is a hollow cylinder with an open lower end. The inner sides of the two horizontal sections at the lower part of the secondary keel 13 are provided with arc-shaped elastic locking plates 30 with clamping grooves 300. The main keel 12 and the secondary keel 13 are quickly assembled and limited by the engagement of the clamping plates 3 and the clamping grooves 300.

[0033] like Figure 2 、 Figure 3 and Figure 4 As shown, a limiting column 200 is coaxially fixedly installed on the lower end of the fixed plate 20 , and the limiting column 200 slides through the grid frame node to the corresponding adjustment seat 10 .

[0034] like Figure 5 and Figure 6 As shown, the card plate 3 is in an inverted L-shaped structure, and the horizontal section of the card plate 3 is provided with an inclined surface, and the horizontal section of the card plate 3 is partially embedded in the card slot 300 .

[0035] like Figures 1 to 6As shown, during the specific work, first clean the ground base, then repair the cracks and level it, ensure that there are no protrusions or loose particles on the surface, and then lay a waterproof layer to reduce moisture penetration, and then arrange the adjustment seat 10 according to the preset spacing, and fix the adjustment seat 10 on the waterproof layer through expansion bolts, then adjust the height of the adjustment seat 10, and use a level to calibrate to ensure that the top surfaces of all adjustment seats 10 are in the same plane, and then clamp the main keel 12 and the adjustment seat 10. After the main keel 12 is installed, the secondary keel 13 is vertically installed on the main keel 12 to make the inclined surface of the card plate 3 It interferes with the elastic locking plate 30 to push the elastic locking plate 30 to undergo elastic deformation, so that the secondary keel 13 can enter the limiting groove, and then the secondary keel 13 is moved forward and backward to ensure that the card plate 3 is accurately aligned with the card slot 300. Once the card plate 3 and the card slot 300 are aligned, the elastic locking plate 30 is not squeezed by the card plate 3 and returns to its original state. The card plate 3 is located in the corresponding card slot 300. At this time, the secondary keel 13 cannot move forward and backward, thereby limiting the forward and backward and up and down movement of the secondary keel 13. The left and right movement of the secondary keel 13 is limited by the limiting groove to significantly reduce the risk of overall deformation of the grid frame.

[0036] Next, the composite sandwich panel 11 is installed on the grid frame. The limiting column 200 on the fixed plate 20 passes through the corresponding main keel 12 and the auxiliary keel 13 to the adjustment seat 10. At the same time, the corresponding driving plate 22 below the fixed plate 20 contacts the upper end of the grid frame. The corresponding four extrusion blocks 21 are synchronously gathered toward the center of the fixed plate 20, applying centripetal clamping force to the four outer corners of the grid frame node (such as Figure 3 As shown), the squeezing force of the extrusion block 21 on the grid frame can change with the pressure force of the composite sandwich panel 11, thereby continuously ensuring the overall strength of the grid frame and ensuring that the position of the composite sandwich panel 11 remains unchanged, thereby avoiding damage to the sealant at the subsequent joint position due to movement. After the composite sandwich panel 11 is installed, the joint is filled with sealant to seal.

[0037] like Figure 3 and Figure 4 As shown, the extrusion block 21 has an isosceles trapezoidal structure, and the inclined surfaces of the extrusion block 21 are provided with inclined grooves 210 inclined from top to bottom toward the center of the corresponding fixed disk 20, and both ends of the driving plate 22 are equipped with guide columns 221 that slide with the corresponding inclined grooves 210.

[0038] like Figure 3 and Figure 4 As shown, a pair of compression springs 220 are installed between the driving plate 22 and the fixed plate 20. A pair of slots are opened at the lower end of the fixed plate 20 and at positions corresponding to the driving plate 22, and the compression springs 220 are located in the corresponding slots.

[0039] like Figure 3As shown, the lengths of two limiting columns 200 corresponding to the same composite sandwich panel 11 and in a diagonal relationship are greater than the lengths of the remaining limiting columns 200.

[0040] like Figures 1 to 6 As shown, during the specific work, during the installation of the composite sandwich panel 11, the longest limit column 200 will preferentially contact the grid frame node when installing the composite sandwich panel 11, forming a preliminary positioning reference, helping the operator to quickly align the position of the composite sandwich panel 11, and avoiding installation deviation due to multi-directional alignment. Then the corresponding driving plate 22 below the fixed plate 20 first contacts the upper end of the grid frame, and under the deadweight of the composite sandwich panel 11, the composite sandwich panel 11 continues to move downward until it fits with the grid frame. During this process, the driving plate 22 contacting the upper end of the grid frame compresses the compression spring 220, and the distance between the driving plate 22 and the lower end surface of the fixed plate 20 gradually decreases. The driving plate 22 drives the corresponding extrusion blocks 21 to synchronously converge toward the center through the cooperation of the guide column 221 and the inclined groove 210, and the four extrusion blocks 21 at the lower end of the fixed plate 20 are synchronously aligned with the grid frame node. The outer corners of the points fit tightly together, and one extrusion block 21 corresponds to one outer corner, but at this time the compression spring 220 is not in a fully contracted state; when the composite sandwich panel 11 is pressed and sinks, the driving plate 22 further moves and compresses the compression spring 220, and the distance between the driving plate 22 and the lower end surface of the fixed plate 20 is further reduced, thereby causing the four extrusion blocks 21 at the lower end of the fixed plate 20 to further clamp the outer corners of the grid frame nodes, so that the vertical load is decomposed into a lateral extrusion force, offsetting the instantaneous sinking trend of the composite sandwich panel 11, and limiting the displacement within a controllable range. The additional pressure generated by the extrusion blocks 21 forms a rigid reinforcement layer, which reduces the displacement of the composite sandwich panel 11 and the grid frame, avoids local collapse or dislocation, and the extrusion blocks 21 disperse the concentrated load to multiple nodes, avoiding stress concentration at the joints due to local overload, thereby reducing the risk of cracking in the joints.

[0041] like Figures 1 to 6 As shown, in addition, the present invention also provides a method for constructing an assembled thermal insulation floor, which is completed with an assembled thermal insulation floor structure and includes the following steps: S1, first cleaning the base layer and then leveling it, and then laying a waterproof layer on the base layer.

[0042] S2. Place the adjustment seat 10 at the corresponding position according to the designed spacing, and then fix it on the waterproof layer with expansion bolts.

[0043] S3. Fix the main keels 12 to the corresponding adjustment seats 10 in sequence.

[0044] S4. Install the secondary keel 13 vertically on the main keel 12 and press the secondary keel 13 so that the clamping plate 3 squeezes the elastic locking plate 30 and deforms until the secondary keel 13 enters the limiting groove. Then move the secondary keel 13 back and forth. At the moment when the clamping plate 3 is aligned with the locking groove 300, the elastic locking plate 30 quickly returns to its original shape so that the clamping plate 3 is located in the locking groove 300, thereby limiting the movement of the secondary keel 13.

[0045] S5. Make the limiting column 200 pass through the main keel 12 and the secondary keel 13, and install the composite sandwich panel 11 on the grid frame. At this time, the corresponding driving plate 22 presses the upper end of the grid frame and compresses the corresponding compression spring 220. At the same time, the four extrusion blocks 21 at the lower end of the fixed plate 20 clamp the outer corners of the grid frame nodes. When the composite sandwich panel 11 is pressed downward, the four extrusion blocks 21 will further clamp the outer corners of the grid frame nodes, and the greater the pressure, the greater the force of the extrusion blocks 21 on the grid frame.
