Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of assembled floor, more particularly, to a keel system and installation method of assembled floor. BACKGROUND

[0002] Floor paving is one of the links in decoration. Traditional floor paving often uses wooden boards or ceramic tiles to be directly laid on the floor or floor slab, which has a long construction period, and the floor is closely attached to the floor or floor slab, so that indoor wiring can only be laid from the top of the floor, which is not only inconvenient but also not beautiful. Therefore, some assembled floor structures that are convenient to install and wire have appeared in the prior art, including floor boards and floor adjusting feet for supporting and connecting the floor boards, and some of the adjusting feet can not only provide bottom support for the floor boards but also control the installation height of the floor boards on the floor. For example, the leveling feet in the floor levelling device and laying method disclosed in the patent with the application number CN201910324406.8; and the network floor adjusting foot mounting structure disclosed in the patent with the application number CN202122969758.4.

[0003] Specifically, the network floor adjusting foot mounting structure includes a base member, a support member is mounted on the base member, and a floor member is connected and supported on the support member; the base member and the support member are connected through a threaded connection structure, and the installation height of the support member is adjusted by screwing the support member; a screwing part is provided on the support member and inserted into the mounting hole of the floor member, and the mounting hole is a through hole.

[0004] It should be noted that in the technical solution of the above patent, the adjusting feet (leveling feet) are independent components, and each adjusting foot directly supports and connects a plurality of floor members. During construction, the adjusting foot components need to be positioned on the laying base first, and then the floor members are connected to the adjusting foot components. If the adjusting feet are fixedly connected to the laying base through a screw structure, it is necessary to perform a punching operation on the laying base, which not only damages the original structure of the laying base but also greatly increases the construction difficulty and construction time. If the adjusting feet are simply placed on the laying base, the adjusting feet are prone to move or fall during installation, which increases the difficulty of installing the floor members. SUMMARY

[0005] The purpose of the present application is to overcome the shortcomings of the prior art, provide a keel system for assembled floor, change the positioning mode of the original adjusting feet, and connect and position the adjusting feet without damaging the laying base, which facilitates the subsequent installation of the floor members. And based on the system, an installation method of assembled floor is provided.

[0016] The position height of said support keels on said first support screw is changed by screwing said first support screw.

[0017] Further as a preferred solution, said connecting hole is a through hole, and a connecting nut is fixedly connected to said connecting plate at a position adapted to said connecting hole, and said first support screw is screwed to said connecting plate through said connecting nut.

[0018] Further as a preferred solution, said adjustable feet comprise:

[0019] A second support screw, with a support seat fixedly connected to a lower end and placed on an installation base surface through said support seat, and an upper end placed above said connecting plate through said connecting hole;

[0020] A support nut, screwed to said second support screw below said connecting plate and providing a bottom support to said connecting plate;

[0021] A position-limiting nut, screwed to said second support screw above said connecting plate and constituting a clamping structure acting on said connecting plate together with said support nut.

[0022] The support nut and the limiting nut are twisted to change the position height of the support joist on the second support screw.

[0023] Further preferably, two adjusting foot members are provided on the support joist at positions corresponding to each of the clamping joists, and the two adjusting foot members are symmetrically arranged on both sides of the clamping joist.

[0024] Further preferably, the support joist is provided with a mounting groove corresponding to the outer contour of the clamping joist, and the clamping joist is adapted to be embedded in the mounting groove through a clamping structure.

[0025] Further preferably, the clamping structure comprises:

[0026] a first guide channel provided on the side wall of the clamping joist;

[0027] a second guide channel provided on the side wall or the upper end surface of the clamping joist in communication with the first guide channel;

[0028] a clamping portion provided on the side wall of the mounting groove, and the clamping portion comprises a protruding portion, and a clamping groove is formed between the protruding portion and the side wall of the mounting groove;

[0029] The clamping portion is placed in the second guide channel under the guidance of the first guide channel and the second guide channel, and the side wall of the clamping joist is embedded in the clamping groove.

[0030] Further preferably, the lower end of the adjusting foot member is provided with a gasket member, and the adjusting foot member is placed on the installation base surface through the gasket member.

[0031] A mounting method of a prefabricated floor, comprising the steps of:

[0032] S1: determining the number of support joists and the placement position on the installation base surface according to the construction design requirements;

[0033] S2: placing the support joist provided with an adjusting foot member on the installation base surface according to the position, and using the adjusting foot member as the bottom support structure of the support joist;

[0034] S3: clamping the clamping joist on the support joist to complete the limiting connection of the support joist;

[0035] S4: adjusting the adjusting foot member according to the level meter to make the upper part of the clamping joist at the same level;

[0036] S5: install the floor piece on the clamping keel, and complete the laying.

[0037] The main beneficial effects of the above technical solutions are:

[0038] 1. The installation mode of the adjusting foot piece is optimized. The adjusting foot piece is connected to the support keel, and the support keel is connected with the clamping keel, so that the adjusting foot piece is positioned on the keel system formed by the support keel and the clamping keel to provide support for the floor piece. In this way, stable positioning of the adjusting foot piece can be provided without damaging the installation base surface, and the adjusting foot piece is prevented from tilting during installation of the floor piece.

[0039] 2. The support mode for the floor piece is optimized. Compared with the original multi-point installation mode in which the floor piece needs to be installed on independent and separate adjusting foot pieces, the formation of the overall keel system and the installation of the floor piece on the keel system can provide a larger and more stable installation surface for the floor piece, facilitate installation of the floor piece, and also provide more stable support.

[0040] 3. The leveling mode is optimized. Compared with the original mode in which the floor piece is directly installed on the adjusting foot piece and thus needs to be leveled for each floor piece, the present application only needs to level the clamping keel to keep the clamping keel providing horizontal installation support for the floor piece, greatly improving the leveling efficiency and shortening the construction period.

[0041] 4. The protection structure formed by the protection wall can provide lateral protection for the adjusting foot piece, reducing the possibility of direct impact of external objects on the adjusting foot piece, so that the adjusting foot piece can always provide stable support for the keel system.

[0042] 5. The adjusting foot piece structure can be selected according to the needs. The upper end of the first support screw rod inserted through the connecting hole and placed above the connecting plate is provided with a screwing part adapted to engage a screwing tool, which facilitates direct screwing of the first support screw rod from above the support keel to change the position height of the support keel on the first support screw rod, and facilitates subsequent leveling operation.

[0043] 6. The first support screw rod is screwed to the connecting plate through the connecting nut, which can more conveniently adjust the connection position of the first support screw rod on the support keel according to the needs of the construction site.

[0044] 7. The adjusting foot piece is symmetrically arranged on both sides of each clamping keel, which can provide stable support for each clamping keel, and thus keep the overall keel system stable.

[0045] 8、The clamping position keel is clamped on the supporting keel, without screw fixing, high installation efficiency; meanwhile, it is convenient for subsequent disassembly to recycle the keel system. Meanwhile, the clamping position keel is adapted to the structure embedded in the installation groove through the clamping position structure, which can improve the connection stability between the clamping position keel and the supporting keel, and further improve the overall connection stability of the keel system.

[0046] 9、The adjusting foot piece is placed on the installation base surface through the gasket piece, which can protect the lower end of the adjusting foot piece and slow down the friction damage of the adjusting foot piece. Meanwhile, the gasket piece adopts a high-friction coefficient rubber pad structure as described below, which can increase the friction between the installation base surface to improve the stability of the keel system on the installation base surface.

[0047] Further or more detailed beneficial effects will be described in the specific embodiments in the specific embodiments. BRIEF DESCRIPTION OF DRAWINGS

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0060] As an embodiment of the present application:

[0061] A keel system of an assembly type floor, referring to the drawings Figure 1 to the drawings Figure 7 , mainly comprises a support keel 1, an adjusting foot member 2 and a locking keel 3, wherein, as shown in the drawings Figure 7 , a plurality of transverse support keels 1 and a plurality of longitudinal locking keels 3 connected to the support keels 1 together constitute a keel frame structure, the adjusting foot member 2 is positioned and arranged on the keel frame, and the floor member 4 is laid above the keel frame to form an assembly type floor structure. In this way, the keel frame, on the one hand, connects a plurality of adjusting foot members 2 in a keel system, provides a position for positioning and mounting the adjusting foot member 2, and also provides transverse support to prevent the adjusting foot member 2 from falling; on the other hand, compared with the original multi-point mounting mode in which the floor member 4 needs to be mounted on a separate adjusting foot, the keel frame provides a larger and more stable mounting surface for supporting and connecting the floor member 4, facilitates the mounting of the floor member 4, and also provides more stable support.

[0062] Specifically, as shown in the drawings Figure 2 , the support keel 1 in the embodiment comprises a connecting plate 101 and a protective wall 102, wherein the connecting plate 101 is provided with a plurality of connecting holes 1011 for positioning and connecting the adjusting foot member 2, and the protective wall 102 is arranged on both sides of the connecting plate 101, and the two protective walls 102 together constitute a protective structure for the adjusting foot member 2.

[0063] As attached Figure 1 As shown, several adjustable feet 2 are positioned and connected to the supporting keel 1, forming a bottom support structure that acts on the supporting keel 1. The height of the supporting keel 1 can be changed by adjusting the adjustable feet 2. Depending on the adjustment method, there are two main types of adjustable feet 2.

[0064] Structure 1: As attached Figure 2 As shown, the adjusting foot 2 includes a first support screw a201, which is screwed onto the connecting plate 101. Its lower end is rotatably connected to a support member a202, preferably made of PVC material, so that the first support screw a201 is placed on the mounting base (the support surface for the keel system, generally the ground or floor) via the support member a202. Its upper end passes through the connecting hole 1011 and is positioned above the connecting plate 101, and is provided with a turning part a2011 adapted to engage a tightening tool. Specifically, the turning part a2011 is a flathead notch adapted to a flathead screwdriver, a Phillips head notch adapted to a Phillips head screwdriver, or an external hexagonal structure adapted to a hex wrench, etc. The position and height of the supporting keel 1 on the first support screw a201 can be changed by tightening the first support screw a201 using a tightening tool.

[0065] Of course, the connecting hole 1011 can be set as a threaded hole to accommodate the screwed first support screw a201. However, in actual construction, it is sometimes necessary to change the installation position of the adjusting foot 2 on the connecting plate 101 according to construction requirements, and it is difficult to drill holes and apply threads to the connecting plate 101 on site. Therefore, in this embodiment, the connecting hole 1011 is a through hole, and a connecting nut a203 is fixedly connected to the connecting plate 101 at the position of the connecting hole 1011. The first support screw a201 is screwed to the connecting plate 101 through the connecting nut a203. In this way, it is only necessary to drill a hole in the connecting plate 101 according to the required installation position of the adjusting foot 2, and fix the connecting nut a203 to the connecting plate 101 vertically aligned with the hole. Specifically, the connecting nut a203 can be as shown in the attached figure. Figure 2 The first support screw a201 is welded to the connecting plate 101 as shown, or is fixedly embedded in the connecting plate 101. The upper end of the first support screw a201 passes through the connecting nut a203 that is adapted for screwing and is positioned above the connecting plate 101 through the connecting hole 1011. The position and height of the support keel 1 on the first support screw a201 can be changed by turning the first support screw a201.

[0066] Structure 2: As attached Figure 3 As shown, the adjusting foot 2 includes a second support screw b201, a support nut b203, and a limit nut b204.

[0067] Specifically, the lower end of the second support screw b201 is fixed to a support base b202 and rests on the mounting base surface via the support base b202. The upper end of the second support screw b201 passes through the connecting hole 1011 and rests above the connecting plate 101. The support nut b203 is screwed onto the second support screw b201 below the connecting plate 101 and provides bottom support for the connecting plate 101. The limiting nut b204 is screwed onto the second support screw b201 above the connecting plate 101 and together with the support nut b203, forms a clamping structure acting on the connecting plate 101. By rotating the support nut b203 and the limiting nut b204, the position and height of the support keel 1 on the second support screw b201 can be changed.

[0068] Of course, in both Structure 1 and Structure 2, to avoid excessive frictional wear between the adjusting foot 2 and the mounting base, a shim 5 is provided at the lower end of the adjusting foot 2. The adjusting foot 2 is placed on the mounting base via the shim 5. Furthermore, the shim 5 is preferably a rubber pad structure with a high coefficient of friction, which can increase the friction between it and the mounting base to improve the stability of the keel system on the mounting base.

[0069] As attached Figure 7 As shown, to prevent the supporting keel 1 equipped with adjusting feet 2 from tipping over, several spaced supporting keels 1 are simultaneously connected to the same locking keel 3 to form a limiting connection structure acting on the supporting keel 1. Meanwhile, the floor piece 4 can be as shown in the attached diagram. Figure 7 As shown, the floor pieces are installed on the mounting brackets 3, and each mounting bracket 3 provides installation support for several floor pieces 4; the floor pieces 4 can also be installed on the supporting brackets 1. In this embodiment, the mounting brackets 3 have an inverted triangular structure, which can provide stable support. The floor pieces 4 are installed on the upper surface of the mounting brackets 3, that is, the upper surface of the mounting brackets 3 constitutes the above-mentioned mounting surface for supporting and connecting the floor pieces 4.

[0070] The locking keel 3 can be connected to the supporting keel 1 via a threaded structure or a pin structure. To improve installation efficiency and avoid using screws and pins, in this embodiment, the locking keel 3 is snapped onto the supporting keel 1. Specifically, the supporting keel 1 is provided with a mounting groove 103 that adapts to the outer contour of the locking keel 3, and the locking keel 3 is fitted into the mounting groove 103 through a locking structure.

[0071] Specifically, the steps for engaging the locking keel 3 with the supporting keel 1 are as follows: Figure 5 To be continued Figure 6As shown. In this embodiment, a first guide channel 301 is provided on the side wall of the locking keel 3, and a second guide channel 302 communicating with the first guide channel 301 is provided on the upper surface of the locking keel 3. Of course, the second guide channel 302 can also be provided on the side wall of the locking keel 3. A locking part 1031 is provided on the side wall of the mounting groove 103 to fit the position of the second guide channel 302, and the locking part 1031 includes a protrusion 1031a, and a locking groove 1031b is formed between the protrusion 1031a and the side wall of the mounting groove 103. In actual installation, the locking part 1031 enters and is placed in the second guide channel 302 under the sequential guidance of the first guide channel 301 and the second guide channel 302, so that the side wall of the locking keel 3 is embedded in the locking groove 1031b.

[0072] Furthermore, as shown in the appendix Figure 4 As shown in this embodiment, on the supporting keel 1, two adjusting feet 2 are provided at intervals at positions that adapt to each locking keel 3, and the two adjusting feet 2 are symmetrically distributed on both sides of the locking keel 3. In this way, on a supporting keel 1, for each locking keel 3 connected to the supporting keel 1, there are two adjusting feet 2 symmetrically distributed on both sides of the locking keel 3 with the locking keel 3 as the center of symmetry, to provide balanced support for the locking keel 3 and improve the overall support stability.

[0073] As a second embodiment of the present invention:

[0074] A method for installing prefabricated flooring, comprising the following steps:

[0075] S1: Determine the number of supporting keels 1 and their placement on the installation base according to the construction design requirements;

[0076] S2: Place the support keel 1 with the adjusting feet 2 on the mounting base according to the position, and make the adjusting feet 2 serve as the bottom support structure of the support keel 1.

[0077] S3: Attach the locking keel 3 to the supporting keel 1 to complete the limiting connection of the supporting keel 1;

[0078] S4: According to the level, the level is placed on the locking keel 3. Following the level's indication, the height of the support keel 1 on the adjusting foot 2 is adjusted by turning the first support screw a201, or by turning the support nut b203 and the limiting nut b204, thereby adjusting the height of the portion of the locking keel 3 connected to the support keel 1 to level the keel 3. This action is repeated to level each locking keel 3, ensuring that the upper heights of several locking keels 3, for example, in this embodiment, are at the same level.

[0079] S5: Install the floor member 4 on the clamping keel 3 to complete the laying.

[0080] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined by the claims and their equivalents.
